Hydraulic control system for paver and paver

Abstract

The invention relates to a hydraulic control system for a paver and a paver, wherein the hydraulic control system for the paver comprises a left end telescopic device, a right end telescopic device and a mechanical synchronous transmission mechanism which is provided with two output ends; the two output ends are respectively arranged on oil supply paths of the left end telescopic device and the right end telescopic device; the mechanical synchronous transmission mechanism can enable the two output ends to synchronously move so that the flows of hydraulic oils, which pass through the two outputends and flow to the left end telescopic device and the right end telescopic device are as same as each other; therefore, the operation consistency of the left end telescopic device and the right endtelescopic device is guaranteed and the molding quality of road surface laid by the paver is improved.

Description

technical field [0001] The invention relates to the technical field of paver, in particular to a hydraulic control system of a paver and a paver. Background technique [0002] In the road construction and maintenance construction, the paver is a kind of construction equipment mainly used for the paving of various materials on the base and surface of the road. The screed is the main working device of the paver. According to the different lengthening methods of the screed, the screed can be divided into two structural forms: mechanical assembled screed and hydraulic telescopic screed. Mechanically assembled screeds are widely used in the paving construction of large-width and large-thickness roads due to their good structural rigidity. In the construction of most highways, according to the special needs at both ends of the road, such as the reservation of the drainage outlet, the preset of the emergency lane, etc., the two ends of the mechanically assembled screed are require...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the mechanically assembled screeds on the market are equipped with endless expansion and contraction. Even if the expansion and expansion configuration is added, due to the influence of the hydraulic control circuit of the vibrating motor of the screed, the speed of the transmission shaft at both ends of the expansion section is inconsistent or the rotation speed of the transmission shaft at both ends of the expansion section is different from that of the screed. The speed of the drive shaft in the base section is inconsistent, or the telescopic vibrating motors at both ends cannot be independently controlled, which will affect the forming quality of the road surface and cause waste of hydraulic energy.
