Description

Technical Field

[0001] The utility model belongs to the technical field of pipe clamps, and in particular relates to a pipe clamp for a high-pressure pipeline of a main pump of an excavator. Background Art

[0002] Excavators are a common type of construction machinery. They are widely used in water conservancy projects, transportation, power engineering, mining and other construction projects due to their multifunctionality, strong adaptability and high efficiency. The hydraulic system is the core component of the excavator, and the main pump is one of the main components of the hydraulic system. It is an energy conversion device that converts the mechanical energy output by the engine into hydraulic energy. The high-pressure pipeline on the main pump is used to transport high-pressure hydraulic oil. Under normal working conditions, the high-pressure pipeline has high pressure and strong vibration. If it is not fixed, it will cause the high-pressure pipeline to loosen, which will cause the excavator to malfunction, affecting the construction progress and increasing the maintenance cost of the excavator.

[0003] At present, the high-pressure pipeline of the excavator main pump is fixed with a sheet-like butterfly pipe clamp, but the overall mechanical strength of this pipe clamp is weak, and the fastening structure is set in the middle of the sheet-like butterfly pipe clamp. Under the strong pressure and vibration of the main pump high-pressure pipeline, it is easy to crack, which increases the replacement and maintenance costs and is difficult to meet the fixing needs of the high-pressure pipeline.

[0004] Meanwhile, the existing pipe clamps of other structures are directly welded to the fixing plate or the excavator body, and the installation position and direction of the pipe clamp cannot be adjusted according to the actual direction of the high-pressure pipeline. Utility Model Content

[0005] The utility model aims to provide a pipe clamp for the high-pressure pipeline of the main pump of an excavator. The high-pressure pipeline is fixed by a square pipe clamp with high mechanical strength, which greatly reduces the risk of cracking of the pipe clamp. At the same time, an arc groove is opened on the fixing plate, and the square pipe clamp is fixed to the fixing plate by fasteners, so that the installation position and direction of the square pipe clamp can be adjusted according to the actual direction of the high-pressure pipeline.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] The embodiment of the utility model provides a pipe clamp for the high-pressure pipeline of the main pump of an excavator, comprising a square pipe clamp, a fixing plate, and a fastener. The square pipe clamp is composed of a cover plate and a bottom plate, the cover plate and the bottom plate are arranged opposite to each other, and threaded holes are respectively arranged at both ends of the cover plate and the bottom plate; a semicircular through groove is arranged on the opposite surface of the cover plate and the bottom plate, and the semicircular through groove is used to fix the high-pressure pipeline of the main pump of the excavator;

[0008] The top and bottom ends of the fixing plate are respectively provided with arc grooves, and the fasteners penetrate through the threaded holes and the arc grooves to fix the square pipe clamp on the fixing plate.

[0009] As a further technical solution, the distance between the arc grooves is the same as the length of the square pipe clamp, so that the square pipe clamp can be rotatably installed on the fixed plate along the arc groove.

[0010] As a further technical solution, threaded holes are respectively arranged at corresponding positions of the top end and the bottom end of the cover plate and the top end and the bottom end of the base plate.

[0011] As a further technical solution, the threaded holes are arranged in pairs, which is beneficial to enhancing the fixing strength of the square pipe clamp and the fixing plate.

[0012] As a further technical solution, the semicircular through grooves are arranged in pairs, so as to fix the oil outlet pipe and the oil inlet pipe in the high-pressure pipeline of the excavator main pump at one time.

[0013] As a further technical solution, the semicircular through groove is provided with a shock-absorbing protective sleeve to reduce the vibration of the high-pressure pipeline of the excavator main pump and enhance the stability of the square pipe clamp fixing the high-pressure pipeline of the excavator main pump.

[0014] As a further technical solution, the fixing plate is arranged on the excavator body, and the fixing plate is an L-shaped plate, and the bottom end of the L-shaped plate is fixed to the excavator body by bolts.

[0015] As a further technical solution, the threaded hole and the arc-shaped groove have the same aperture.

[0016] As a further technical solution, the fasteners penetrate the threaded holes provided on the cover plate, the threaded holes provided on the bottom plate and the arc grooves to fix the square pipe clamp to the fixing plate.

[0017] As a further technical solution, the fasteners are bolts and nuts.

[0018] The beneficial effects of the above-mentioned embodiments of the utility model are as follows:

[0019] (1) The high-pressure pipeline is fixed with a square pipe clamp with high mechanical strength, which greatly reduces the risk of cracking of the pipe clamp.

[0020] (2) The top and bottom ends of the fixing plate are respectively provided with arc grooves, and the square pipe clamp can be rotated along the upper and lower arc grooves of the fixing plate, and after the rotation, the square pipe clamp can be fixed to the fixing plate by fasteners, so as to adjust the installation position and direction of the square pipe clamp according to the actual direction of the high-pressure pipeline.

[0021] (3) The fixing plates and square pipe clamps can be prefabricated in advance to adapt to various types of main pump high-pressure pipelines and connected and fixed by fasteners, avoiding the problems of the traditional method of welding the square pipe clamps, which causes the installation angle to be unadjustable, the difficulty of maintenance or replacement, and the low installation efficiency.
