Description

Technical Field

[0001] The utility model relates to a hydraulic pipe clamp device and a multifunctional bracket, belonging to the technical field of mining dump trucks. Background Art

[0002] The articulated dump truck is mainly composed of power system, electrical system, hydraulic system, cab, safety protection, frame, cargo compartment, suspension system, cover, transmission system, etc. Each system is located on the frame, and the frame is connected to the drive axle in the transmission system through the suspension system. The frame consists of a front frame, an articulated body, and a rear frame. The front and rear frames can achieve 45° left and right twisting and 360° rotation along the central axis through the articulated body. The left and right steering is achieved by controlling the movement of the steering cylinder. The articulated dump truck has the functions of driving, steering, braking, lifting, etc. There are many hydraulic pipes and wiring harnesses between the front and rear frames. Due to space limitations, it is difficult to install and fix. When fixing the hydraulic pipeline, a cable tie or clamp is generally used to fix it on a bracket or threaded seat nearby. Due to the poor road conditions of the articulated dump truck, the cable tie or clamp is prone to loosening after running for a period of time. The hydraulic pipe harness is easily damaged after falling off, resulting in vehicle operation failure and immeasurable economic losses. In order to prevent the hydraulic pipeline from loosening, a hydraulic pipe fixing bracket with low manufacturing cost, easy operation, safety and reliability is needed. Summary of the invention
