Construction machinery house Dingsheng WTD7500 paver support wheel

In recent years, with the rise of road construction, road machinery has also been widely applied. Paver is the most common road construction of a road machinery, on paver, construction machinery home with a number of high-quality accessories, today, Xiaobian introduced to you is one of the heyday of WTD7500 paver support wheel.

There are many kinds of paver wheel in construction machinery house:

WTD7500 paver roller, WTD7511 paver roller, WTL7511 paver roller, WTD9000 paver roller, WTD9001A paver roller, WTL9011 paver roller, WTL9012 paver roller, WTD9500 paver roller. WTD9501A paver roller, WTD9512 paver roller, WTL9522 paver roller, WTD12012 paver roller, WTL4500 crawler paver.

The support wheel is prone to problems

A and wheel wear. The reason for this is that the steel used is not qualified, or the hardness of the material is lower than that of the heat treatment, and the wear resistance is insufficient;

B, oil leakage. The supporting wheel shaft is always rotating through the axle sleeve, and the inner part of the wheel needs oiling to lubricate, but if the sealing ring is not good, the oil leakage phenomenon is easy to occur, so that the shaft and the shaft sleeve are easy to be worn without lubrication, and the product can not be used.

There are several reasons for the oil leak:

1 floating oil seal is not qualified

2. the roundness of product bushing is not enough

3. axis glossiness is not enough

4. gear oil not up to standard

5. the machining dimension tolerance and so on will result in the oil leakage of the support wheel.

Operation procedures of maintenance stage after paver operation

1. after finishing the paving work, routine maintenance work should be carried out according to the routine maintenance (daily maintenance) regulations.

2. the working device and moving mechanism of paver which has direct contact with asphalt mixture, after operation, spray with diesel oil and then run for a period of time, remove the residual asphalt on it, make it run freely and flexibly. It is forbidden to spray the diesel fuel to the electronic control system and the spiral line, so as to prevent the fire from burning when the power is switched on.

3. paving two lime soil operation, washed with water, white material washed, washed with the use of waste hydraulic oil lubrication scraper conveyor chain parts, piston rod coated antirust oil. Be careful not to wash water into electrical and bearing parts to prevent short circuit and foreign matter from entering the bearing.

4. wipe the surface of the hydraulic telescopic ironing guide sleeve and the surface of the telescopic sleeve. For a period of time unused, it should be coated with anti rust oil and then retracted into the cylinder; if it can not be retracted, it should be wrapped with newspaper coated with grease.

5. clean and check the longitudinal slope instrument adjustment device, lubricating grease lubrication of the screw. Grease the float arm rail. Grease points at each injection point until the seams overflow. The spreading machine with oiling cup should observe the consumption and fill it at any time.

6. paver cleaning work should be carried out in the work place, need to do the cleaning work in work field, to have paved asphalt pavement covered with a layer of plastic cloth, so the residual flow in the cleaning process of asphalt and waste diesel oil flow to the plastic cloth after clean, no residue of logistics to diesel asphalt paved road, to prevent the corrosion of asphalt pavement.

7. the driver should leave the driving platform and stop the paver. The brake must be reliable. Both sides of the hopper are put down. The iron plate is placed on the ground or hanging with a hook. Pull out the starting key, cover the protective cover, lock the central control box, turn off the power switch.

8. before the work, the captain should organize the longitudinal slope instrument, horizontal slope instrument, spiral, manual cross slope setting device and the total control box and other packing back to the station, special personnel custody, to prevent loss. Second days to work and then shipped back to the site, installation, commissioning, continue to work.

9. paver parked in the vicinity of the traffic lane, must be set around the obvious safety signs, to avoid other vehicles hit the paver, night warning red light signal and send someone to guard.
