Abstract

The invention discloses a hydraulic control device of a road guardrail breakdown van, and belongs to road guardrail breakdown van. The hydraulic control device comprises a swivel joint, an operation controller, a drilling controller, a supporting leg controller and an oil pump assembly; the oil pump assembly outputs to the supporting leg controller, and the supporting leg controller outputs to the swivel joint and outputs to the operation controller and the drilling controller; and a pile driver is driven and controlled to work. The hydraulic control device has the advantages that the structure is simple, the size is small, one hydraulic controller can control hydraulic components of the whole vehicle, normal operation of road repair is effectively controlled and driven, control is convenient, particularly, one hydraulic controller comprises a piling hydraulic control device and a drilling machine hydraulic control device, multiple functions of piling, pile pulling and drilling can be achieved through one device, and the labor intensity of workers is greatly reduced.

Description

technical field [0001] The invention relates to a road guardrail emergency repair vehicle, in particular to a hydraulic control device for a highway guardrail emergency repair vehicle. Background technique [0002] At present, people use highway guardrail rush repair vehicle to carry out piling or maintenance, rush repair construction to highway guardrail pile. The existing highway guardrail emergency repair vehicle can adjust the verticality of the column in the pitch direction by adjusting the pitch direction of the column, but cannot adjust the verticality of the left and right directions of the column. When using the existing highway guardrail emergency repair vehicle to carry out drilling or piling, the air motor or pneumatic impactor is used. Therefore, it is necessary to be equipped with a large air compressor installed on a special trailer to meet the working requirements of the pneumatic impactor. The guardrail emergency repair vehicle is bulky, the product is heav...
