The roadside machine belongs to the category of road equipment in construction machinery. It is widely used in high -level highways, railway, airport runways, dams, stadiums and other large engineering projects to compact and compact operations.Road base stable soil and asphalt concrete road layer.Lets take a look at how to operate safely on the road press?What should I do if there is a fault in the road?
Safety operation
It is determined that the diesel engine and the throttle handle is the medium speed position (re -re -renewed to the high speed after the pressure of the road machine starts).Step the clutch pedal to cut off.Push or pull down the handle in the direction of walking.Determine the driving speed of the road press, pull the transmission rod to the need for the gear, the first gear is the work efficiency, the second gear and the transportation speed, the three -gear is the transportation speed, and only allows driving on a good flat road surface.Best the wrench.Release the clutch pedal.The following explanations are the precautions for operating the road press.
Precautions for operating the rollers
The roller is walking forward or backwards. At this time, you should first try whether the foot brake is sensitive.Note: Dont be too hard when you step on your feet. Dont forget to step on the clutch first.Try the steering wheel in place, whether the hydraulic steer is effective and reliable.The rear engine accelerator handle makes the engine reach full speed.
Note: When the gear transmission or when the direction is changed, the engine speed should be reduced first, which reduces the speed of the roller. Before the transmission may be transformed, you must step on the main clutch, otherwise the gear will occur early wear or break.Then push a light or light transmission or pour the handle, and the lower to the gear is completely mesh.When manipulating the downhill handle, the movement should be smooth and fast, and do not excessively force.Put it in the middle position for a while (about 10 seconds) to reduce the inertia of the roller forward or backward, and then pull the pouring handle and make it in place to ensure that the gear is completely messed.When the uphill and downhill, the speed of the transmission should be used, and the transmission should be carried out before the uphill or downhill (it is strictly forbidden to change the gear on the slope) uphill.Emergency braking: Step the clutch pedal.When using the foot brake, dont be too hard. In emergency situations, you can tighten your hand brake at the same time.Try to avoid emergency braking at high speeds of the roadside machine, otherwise it will reduce the service life of the braking system.
Precautions for operating the rollers -the steering of the roller press
Turn on the left turn or turn the right turn light switch to light up the corresponding to the light.
When the roller is driving at a high gear (three gears), the manipulation of the throttle should be manipulated to reduce the speed of the presidential route.
Turn the steering wheel to the left (or right) to change the roller.
Note: Be cautious to the steering operation to prevent the road base from the back of the pressure on the road or the road to the road.
Precautions for operating road press -parking
Wall the accelerator handle to the medium speed position to reduce the speed of driving for the pressure.Step on the clutch pedal, place the pouring handle in the middle position, place the gear rod in the empty gear, and release the clutch pedal.Pull up the hand brake.Gradually reduce the engine speed and run at idle speed for 3-5 minutes to reduce the engine temperature.Then pull up the flame door and close the engine.Start the ignition switch to the original position in the right time, and cut off the circuit.Turn off the power switch.
Router maintenance
1. Transmission maintenance
The gearbox is cleaned at least once a season. When washing, first, the parking stuffed oil stuffed on the side of the gearbox was unscrewed in the heat.Diesel engine, make the gearbox run at low speed for 2-3 minutes, stop the kerosene, clean the oil and twist it to the gearbox.Then add new lubricating oil to the marked line of oil surface to the oil ruler.
The gearbox uses No. 20 gear oil.
It is necessary to check and adjust the positioning device of the transmission manipulation mechanism and the replacement mechanism to keep the gear in an appropriate position to avoid causing a starting accident.
Pay attention to check the leakage of each seal of the gearbox. If the sealing part is damaged, it should be replaced in time.
It is necessary to check the gearbox and the rack connection bolts frequently, and tighten it if necessary. Do not loosen and fall off.
Second, hydraulic system maintenance
Check whether the installation bolts of the filter, valve, motor, oil pump, oil cylinder, etc. are loose and whether the joints are leaked at each connector.
Observe the fuel level on the side of the fuel tank. When the hydraulic oil is too small, the same number of hydraulic oil should be filtered.
The hydraulic fuel tank is cleaned once in half a year and changed the oil. When adding or changing oil, be careful not to mix impurities into the fuel tank. The new oil added or replaced must be filtered in advance.
Hydraulic oil is No. 68 anti -abrasion hydraulic oil.
The hydraulic oil filter is cleaned or replaced with the filter element after 500 hours of use.
Third, vibration wheel maintenance
The vibration wheel is replaced with lubricating oil every 1000 hours.Check at any time if the vibration wheel lubricating oil is leaked; when checking the oil level, the refueling port should be turned to the front of the oil level, and the oil is opened to make the oil leak out of the leakage or less leakage.
Replace the vibration wheel lubricant during maintenance, and pay attention to cleaning when changing oil.
Lubricant oil No. 30 CD -class Chai Machine Oil.
The lubrication and maintenance of the bearing should be used to add sufficient calcium base lubrication to the corresponding oil cup position after the entire machine is used for an average of 20 days.
Fourth, main clutch maintenance
In addition to adjusting its manipulation agency at any time, the main clutch should also pay attention to checking and adjusting the end of the three separation rods in the same plane, and keep it from the separation bearings (0.4 to 0.7 mm).
When the main clutch coexistence and departure should be smooth and relaxed, they must not be too hard. When the clutch is junction, the clutch pedal must be returned to the original position, so that the clutch is fully connected.Open, when manipulating, it is necessary to prevent the clutch from being in a semi -clutch and semi -junction state, so as not to burn the clutch.
Check the main clutch frequently to avoid staining oil from the surface of friction pieces and plates.
Five, side transmission maintenance
Due to the low speed, large load, large load, and susceptible to dust and mud, you should often pay attention to checking its lubrication, regularly remove the dirt on the mud, sand, and fine stone dandruff on the gear, and apply a new layer of calcium base lubrication to lubricate.Lipids to avoid damage.
6. Battery maintenance
The battery is used for a long time. If it is improper and maintained at the time, the proportion of common electric hydraulics is low, the voltage is particularly high during charging, and the voltage is very low during discharge."Salt", causing it to be unable to apply. The battery that is salted by acid can be used to recover normal with smaller currents after 1-2 charging.
Check the load and electricity of the battery pack with the proportion of acid to see if the battery is sufficiently loaded. The proportion of the electrolyte should be 1.28 (15OC) when sufficient loads.Charge.
Under normal conditions, the generator of the diesel engine is enough to fully charged the battery, but in winter, the battery pack should pay attention to keeping full state to avoid frozen.
In order to avoid the hardening of the battery electrode and produce sulfuric acid, the battery is in the state of discharge for more than 24 hours. If it is not used for a while, it should be charged once a week until the battery is fully emitted.
The surface of the battery must be kept clean often. If there is dust or electrolyte flowing out, it is best to use a rag with ammonium chloride alcohol or 10%ammonium sulfate liquid.
Seven, maintenance of diesel engines
The maintenance of diesel engines is carried out according to the maintenance manual of diesel engines.
The lubrication of the roller
The lubrication of the roller is removed at the hinge and the ends of the steering oil cylinder uses a lithium -resistant lubricant, and the rest uses ordinary lubricants.

Follow -up repair
1. Following the fuel pipeline air exclusion method
During the use of the diesel engine, the roller was turned off due to the lack of diesel in the fuel tank.Although the diesel engine is turned off, although the oil tank is added with diesel, at this time, the air has entered the air in the diesel pipeline, and the use of a hand oil pump can no longer be restored to oil supply.
In order to eliminate the air in the diesel pipeline and make the diesel engine start smoothly, we adopt the following methods: First, find a small pot and make a certain amount of diesel and place it in a slightly higher position than the diesel pump; second, bring the fuel tank to the fuel tankRemove the diesel pipe connected to the hand oil pump, ** in the small pot of diesel; again, send diesel with the hand oil pump to remove the air in the low pressure oil road clean; finally, the oil tank is loaded with the diesel pipe of the hand oil pump after reinstallingThe test machine, the diesel engine starts normally.
2. Method of damage to the solenoid valve
If the diesel engine is difficult to start, it takes a long time to start the diesel engine to barely start.We initially believe that the injector is caused by poorly worn atomization, but it is good to check the injector and the fuel injection pump.When checking the motor valve again, it is found that its electromagnet is not attractive.
When we launch the solenoid valve to remove it, and take the oil valve stem connected to the solenoid valve by hand, the diesel engine can be started smoothly, which shows that the solenoid valve has been damaged.Since the new solenoid valve cannot be purchased temporarily on the nearby market, we use fine copper wire to bundle the fuel jet pump oil valve stems to prevent them from returning, and thicken the solenoid valve padOil outlet.After the above treatment, the solenoid valve was installed and the road was put into use.After purchasing the newly start -up solenoid valve, replace it.
3. Deformation repair method of the front wheel support
When the static pressure roller was unable to start a failure, at the time, in order to start the roadside machine, the loader was used to start the on -site push.The road press cannot be used.
Generally, the failure of this fault requires disassembling the front wheel box, the vertical shaft and the front fork, but the repair cost is time -effective.To this end, we adopted the following simple recovery method: first, adjust the front wheels to the front direction; second, the front wheels, front wheel frames and front forks beam are cushioned to make it before the turning steering wheel.The wheel does not generate rotation; again, rotate the steering wheel, remember to turn the total number of rotating circles, turn to the extreme position and then return to half of the total number of circles., Remove the 14 fixed bolts on both sides of the front wheel box, and push up about 400mm with the jack to leave the front wheel axis; finally, use the electric welding to weld the vertical shaft sleeve firmly, loosen the pound, and fall before falling.The fork reinstates the front wheel box and the front axis.Only one person can be adjusted to adjust the front wheel frame.
4. Poor repair method
The positioning of the velocity rod of the static light wheel pressure rod is easy to fall or cut off, causing the transmission rod cannot be positioned.This positioning sales diameter is 4mm, which is used to prevent transmission rods from rotating.
In order to solve this problem, we adopt the following methods: First, the diameter of the transmission rod sales holes is expanded to 5mm, and the inner thread of the M6 ??is attacked; second, the width of the transmission groove is 6mm; finally, the M6 ??screw and 1 M6 screw and 1 are configured.Only M6 nuts, twist the screw into the seat holes, and lock the nut after returning half a circle.
5. Sealing ring oil leakage solution
The vibration valve leakage of the vibration roller was replaced after the Y -shaped tight ring was replaced.The inspection found that after the vibration valve was used for a long time, the valve core cover was severely worn between the cap and the valve core.
To solve this problem, we adopt the method of adding an O -shaped or flat sealing ring, and the O -shaped or flat sealing ring is installed in the groove of the Y -shaped seal.There is no oil leakage after the vibration valve is installed and sealing, which proves that the method has achieved better results.
