Problems solved by technology

[0002] The loader has a hydraulic oil delivery pipe, which is a pipe connecting the oil cylinder and the fuel tank. In the prior art, the hydraulic oil delivery pipe is a rubber pipe. In order to enhance the strength of the delivery pipe, some delivery pipes have steel wire mesh inside, but such The outside of the conveying pipe is still rubber. During the use of the loader, the conveying pipe will be worn with the machine, which will affect the service life of the conveying pipe

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown: the loader hydraulic oil delivery pipe, including the pipe body 1, the pipe body 1 is made of rubber, and there is a steel wire mesh in the middle of the pipe body, and the feature is: the pipe body 1 is also wrapped with steel wires 2.

[0012] Further, the steel wires are double-layered, and the coiling directions of the double-layer steel wires are opposite to each other, that is, the inner layer steel wires 21 and the outer layer steel wires 22 .

[0013] Furthermore, the steel wire section is a rectangular structure, and the length of the rectangle is close to the outside of the pipe body.

[0014] During production, the steel wire can also be made into the shape of a spring first, and then the pipe body can be threaded inside. Such a pipe is more wear-resistant and has a longer service life when installed on the loader.

Abstract

The invention relates to the field of building machinery, and relates to a loader. The hydraulic oil delivery pipe for a loader comprises a pipeline body which is made from rubber, and a steel wire mesh is arranged in the middle inside the pipeline body. The hydraulic oil delivery pipe for the loader is characterized in that the exterior of the pipeline body is wound by steel wires, the steel wires are arranged in a double-layer mode, the winding directions of the double-layer steel wires are opposite, the sections of the steel wires are of rectangular structures, and the rectangular length is attached to the outer side of the pipeline body. The hydraulic oil delivery pipe for the loader has the advantages of being durable in use and not prone to wearing. The steel wires are arranged in the double-layer mode, and the winding directions of the double-layer steel wires are opposite, so that the steel wires can be prevented from hanging on objects with edges by the delivery pipe; the sections of the steel wires are of rectangular structures, and the rectangular length is attached to the outer side of the pipeline body, so that the hydraulic oil delivery pipe for the loader has the advantages that the steel wire layers are not too thick, and the use is convenient.

Description

technical field [0001] The invention relates to a construction machine and a loader, in particular to a loader hydraulic oil delivery pipe. Background technique [0002] The loader has a hydraulic oil delivery pipe, which is a pipe connecting the oil cylinder and the fuel tank. In the prior art, the hydraulic oil delivery pipe is a rubber pipe. In order to enhance the strength of the delivery pipe, some delivery pipes have steel wire mesh inside, but such The outside of the conveying pipe is still rubber. During the use of the loader, the conveying pipe will be worn with the machine, which will affect the service life of the conveying pipe. Contents of the invention [0003] The object of the present invention is to provide a durable and wear-resistant loader hydraulic oil delivery pipe for the above-mentioned shortcomings. [0004] The technical solution of the present invention is realized as follows: the loader hydraulic oil delivery pipe includes a pipe body, the pipe...
