Cement stabilized soil paver and its improvement method

Abstract

The invention discloses a cement stabilized soil paver, comprising a rack, a hopper, a thrusting beam, a wheel seat and a thrusting roll. Specifically, the hopper is arranged on the rack, one end of the thrusting beam is hinged to the rack, the thrusting roll is positioned on the wheel seat that is disposed at the other end of the thrusting beam. The paver is characterized in that: section steel with thickness of 20cm is arranged between the thrusting beam and the wheel seat, and the distance between the thrusting roll and the thrusting beam is increased from original 35cm to 55cm; the lengthof the hopper is increased to 200cm and the volume of the hopper is 3.5cm<3>. As the length and volume of the hopper are increased correspondingly, a mixture unloaded from a dump truck cannot be unloaded into an engine room any more. Meanwhile, the paving efficiency is improved. A buffer spring is mounted between the rack and the thrusting beam so as to solve the problem of a rigid collision between the two ends of the thrusting beam and the rack during reversing and unloading of the dump truck, and the impact force of the dump truck on the paver can be buffered and abated, thus reducing the paver change and greatly improving paving quality.

Description

technical field [0001] The invention relates to a cement-stabilized soil paver, in particular to an improvement to the cement-stabilized soil paver. Background technique [0002] Most of our company's XCMG WTU75 cement-stabilized soil paver was purchased between 1999 and 2000, and it has been nearly ten years. The length of the hopper of the paver is 1.8 meters, and the volume of the hopper is about 3 cubic meters. Since there were few large-tonnage dump trucks at that time, they were not yet popularized, so the extension length of the push rollers of this machine was relatively short to meet the work needs. But now, all the transport vehicles are large-tonnage dump trucks of more than 20 tons. When paving, the dump truck often unloads the mixture into the engine compartment of the paver, thus affecting the engine work. For this reason, it is very necessary to carry out technical improvement on the push roller of WTU75 cement-stabilized soil paver to adapt to the current la...

Problems solved by technology

[0003] The hopper of WTU75 Water Stabilized Paver is 180cm long, 290cm wide, the side plate is 60cm high (the lowest point), and the engine compartment baffle is 130cm high. According to calculations, the volume of the hopper of the machine is about 3.1 m3, and the volume and length of the hopper cannot meet the needs of daily work, which has affected the progress of the construction; in addition, because the WTU75 paver push beam The connection with the frame is through the hinge connection in the middle, and the two ends of the push beam and the frame will have a rigid collision when the dump truck reverses and unloads, thus affecting the paving quality
