Slip mode cement concrete pavers from quangongzi's blog

Sliding mode cement concrete paver When laying concrete pavement, the general construction process is: spiral feeder to cement concrete in the width of the wide spread out, adjustable height of the hydraulic scraper to the concrete scraped to the pre-shop height, the hydraulic drive Of the frequency of the vibration into the vibration of the vibrator, so that the concrete to achieve the desired compact effect; and then pound on the board, under the tamping, and further solidified at the same time the surface of coarse aggregate pressure into the cement concrete, forming a thick layer of mortar Layer; and then by the wiping plate and lateral sliding template to squeeze each other to form concrete pavement concrete. Sliding mode cement concrete pavers are usually composed of power transmission system, main frame system, walking system, automatic control system, operating device, auxiliary system and other components. The advantages of the rail paver are simple structure, low price, good reliability, easy maintenance, easy operation, relatively low requirements for the mix; but its construction requires a lot of rails and templates, labor intensity, construction speed And construction quality are relatively low.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery

Cement concrete pavers often appear in the following common faults: cement concrete paver spiral feeder failure spiral feeder in the course of the use of high oil pressure, do not turn the phenomenon, the reason may be from the 4 Aspects. Spiral feeder ends are damaged. Generally due to the bearing outside the oil seal and dust jacket caused by damage. The concrete mortar enters into it to cause the screw feeder to stuck or the resistance is too large, causing serious damage to the bearing. At this point only need to replace the bearings, oil seals and dust cover, add a new lubricant can be. The chain is too long. When the chain is stretched to a certain extent, the sprockets will be stuck in the box box shell, this time to be renewed and filling the oil. Planetary gear reducer. Remove the helical feeder and the sprocket cover, turn the active sprocket, if not turn, just remove the drive wheel to observe the damage to the planetary gear unit. The cause of the damage is generally due to individual gears, ring gear processing caused by poor quality, need to replace the assembly. Hydraulic pump, hydraulic motor failure. If the hydraulic pump is damaged, the indication value of the hydraulic pressure gauge is low; if the hydraulic motor is damaged, the indication value of the hydraulic pressure gauge is also low, and the damaged side has no action. In the event of any of the above, the assembly must be replaced.
