Description

Technical Field

[0001] The utility model relates to the technical field of steering systems for mining vehicles, in particular to a suspension pipeline supporting device for a mining dump truck. Background Art

[0002] A mining dump truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short travel distance and heavy load. It is usually loaded with a large electric shovel or hydraulic shovel, and travels back and forth between the mining point and the unloading point.

[0003] The power steering oil pipe is an important part of the steering system of mining vehicles. Its main function is to provide power steering oil to the steering gear, thereby reducing the steering resistance. The function of the steering pipe bracket is to fix the oil pipe during the actual working process and absorb the vibration caused by the hydraulic fluctuation in the oil pipe.

[0004] The current structure of the steering pipe bracket for mining vehicles is relatively simple, and there are insufficient fixed points around the gearbox, making it impossible to fix and support multiple oil pipes at the same time. If the bracket structure cannot meet the requirements for fixing the oil pipes, it is easy to cause the steering oil pipe to vibrate and deform, or collide with surrounding parts and cause scratches and leakage, and the power-assisting fluid cannot be smoothly delivered to the steering machine, all of which make the steering heavy. Utility Model Content

[0005] The present application provides a suspension pipeline support device for a mining dump truck, thereby solving the problem in the prior art that the steering pipeline support structure of a mining vehicle is single and multiple oil pipes cannot be fixed at the same time. It realizes effective completion of various forms of fixed support for steering pipelines when there is insufficient space and fewer fixing points, thereby reducing oil pipe vibration and the noise generated by it, maintaining the lightness of steering while avoiding interference and wear between the oil pipe itself and other systems.

[0006] The embodiment of the present application provides a suspension pipeline support device for a mining dump truck, comprising:

[0007] A pipe bending bracket, the pipe bending bracket is arched, a mounting hole is provided in the middle of the pipe bending bracket, and both ends of the pipe bending bracket are connected to the powertrain suspension;

[0008] A transverse plate bracket is a long strip of plate, the transverse plate bracket is provided with a plurality of assembly holes, the transverse plate bracket is arranged in the middle of the pipeline bending bracket, and the transverse plate bracket is used to fix the steering pipeline.

[0009] The beneficial effects of the above-mentioned embodiment are as follows: the support device is fixed by using the holes of the suspension system to support and fix the steering pipeline, and the oil pipe is fixed to the cross plate bracket by a pipe clamp, which effectively reduces the vibration of the oil pipe and the noise generated by it, and maintains the lightness of the steering; through the cross plate bracket, multiple power steering oil pipes can be laid in a limited space, saving layout space, simple structure, and easy installation.

[0010] Based on the above embodiments, the present application can be further improved as follows:

[0011] In one embodiment of the present application, three mounting holes are respectively provided at both ends of the pipe bending bracket in a triangular hole position. The pipe bending bracket is connected to the powertrain suspension through bolts and nuts. The arched design of the pipe bending bracket makes it evenly stressed, and is fixed with the triangular hole position to improve the overall strength and rigidity, and effectively increase the stability of the steering pipeline.

[0012] In one of the embodiments of the present application, the assembly clearance of the mounting hole is 2-3 mm.

The aspect ratio of this support device is reasonably designed, and a large distance is left between it and other surrounding systems, which can prevent the wear of the pipeline during the operation of the vehicle, and effectively avoid the problem of collision, scratching and leakage with surrounding components.

[0014] In one embodiment of the present application, the assembly holes in the middle of the pipe bending bracket are arranged in multiple rows at equal intervals, and the number of assembly holes provided by the transverse plate bracket is greater than the number of assembly holes in a single row of the pipe bending bracket. The support device adopts a multi-hole cooperative installation method of the pipe bending bracket and the transverse plate bracket, which can adapt to the changes of various pipelines to the greatest extent and effectively fix them, and has no impact on other systems.

[0015] In one embodiment of the present application, the assembly holes of the pipeline bending bracket are arranged in four rows, two assembly holes are arranged in a single row, and seven assembly holes are arranged at equal intervals on the cross plate bracket. The support device performs real-time front, back, left, and right position adjustment during the actual installation and fixing of the steering pipeline, which is conducive to flexibly adapting to the layout of various pipeline changes, and at the same time facilitates the arrangement of the pipeline and is clear and organized.

[0016] In one embodiment of the present application, two transverse plate brackets are provided, and the two transverse plate brackets are arranged in parallel and spaced apart. The steering pipeline is fixed in two sections, which is more stable.

[0017] In one embodiment of the present application, the pipe bending bracket and the cross plate bracket have a thickness of 7-9 mm. The support device reduces its own weight while ensuring strength.
