[0001] The utility model relates to the technical field of hose fixing, in particular to a hose fixing assembly. Background Art

[0002] During the operation of mining dump trucks, hoses play a crucial role, such as transporting hydraulic oil, coolant, etc. However, due to the harsh working environment of mining dump trucks, they often face severe vibrations, bumps, and various complex working conditions. Traditional hose fixing methods often have the following problems:

[0003] On the one hand, some simple tying or clamping fixing methods are not firm enough. Under the long-term operation of mining dump trucks and harsh road conditions, the hoses are prone to loosening or even falling off.

[0028] As Figures 1 to 3 shown, a preferred embodiment of the present utility model provides a hose fixing assembly, which includes a fixing bracket 1 for fixing on a mining dump truck, a U-shaped bolt 4 for cooperating with the fixing bracket 1 to fix the hose, and a nut assembly 2 for fixing the U-shaped bolt 4 on the fixing bracket 1; at least two bolt fixing holes 102 are provided on the fixing bracket 1, and both ends of the U-shaped bolt 4 pass through a bolt fixing hole 102 respectively, so that the fixing bracket 1 and the U-shaped bolt 4 enclose a loop structure for sleeving outside the hose to fix the hose. Through the cooperation of the fixing bracket 1, the U-shaped bolt 4 and the nut assembly 2, a stable loop structure is formed, providing reliable fixation for the hose, reducing the shaking and displacement of the hose, ensuring the stability of the hose during the working process, contributing to maintaining the normal operation of systems such as the hydraulic system of the mining dump truck, with a simple structure, convenient and fast installation, reducing the installation time and labor cost.

[0029] Specifically, the fixing bracket 1, the U-shaped bolt 4 and the nut assembly 2 are usually made of strong and durable materials, which can adapt to the harsh working environment of the mining dump truck, have high durability, high fixing strength and strong seismic performance.

[0030] Specifically, the fixing bracket 1 includes two bracket plates 103 with parallel lengths, arranged in two mutually perpendicular planes respectively, and their sides are connected to each other. Each bracket plate 103 is provided with a bracket mounting hole 101 and a bolt fixing hole 102. The design of connecting the sides to each other further enhances the strength of the overall structure, enabling it to better withstand the pressure from the rubber hose and external forces such as vibrations and bumps; and the hole positions on different bracket plates 103 can adapt to the fixing requirements of rubber hoses of different specifications, improving the versatility of the fixing bracket 1. In other embodiments, the fixing bracket 1 can also be made non-planar to better fit the surface of the rubber hose, or the fixing bracket 1 can be welded and installed at the relevant fixed position instead of bolt installation.

[0031] In this embodiment, the nut assembly 2 includes an inner adjusting nut 201 and an outer adjusting nut 202. The inner adjusting nut 201 and the outer adjusting nut 202 are sleeved on the same end of the U-shaped bolt 4, and the fixing bracket 1 is clamped between the inner adjusting nut 201 and the outer adjusting nut 202. This enhances the stability and reliability of the rubber hose fixing, and at the same time provides a flexible adjustment function.

[0032] Specifically, the tightening directions of the inner adjusting nut 201 and the outer adjusting nut 202 are opposite. This enhances the clamping stability of the nut assembly 2 on the fixing bracket 1, prevents loosening, and improves the reliability of the rubber hose fixing.

[0033] Specifically, the spacing distance between the fixing bracket 1 and the rubber hose is greater than the height of the inner adjusting nut 201. The end of the U-shaped bolt 4 is formed with a threaded area for cooperating with the nut assembly 2, and the length of the threaded area is greater than the spacing distance between the fixing bracket 1 and the rubber hose and the height of the inner adjusting nut 201.

[0034] In this embodiment, the nut assembly 2 includes two pairs of outer adjusting nuts 202 and one pair of inner adjusting nuts 201. One of each pair of outer adjusting nuts 202 and one of the inner adjusting nuts 201 are sleeved on the same end of the U-shaped bolt 4, and two of the outer adjusting nuts 202 are arranged on one side of the fixing bracket 1, and the inner adjusting nut 201 is arranged on the other side of the fixing bracket 1.

[0035] Specifically, the tightening directions of the two outer adjusting nuts 202 sleeved on the same end of the U-shaped bolt 4 are the same. In this embodiment, the nut assembly 2 adopts a combination of two pairs of outer adjusting nuts 202 and one pair of inner adjusting nuts 201, and the specific arrangement forms a stable clamping structure on both sides of the fixing bracket 1. At the same time, the same tightening direction of the two outer adjusting nuts 202 on the same end further enhances the stability and reliability of the rubber hose fixing and facilitates installation and adjustment.

[0036] In this embodiment, the hose fixing structure further includes a gasket assembly 3 clamped between the nut assembly 2 and the fixing bracket 1. The gasket assembly 3 includes an inner adjusting gasket 302 sleeved on the U-shaped bolt 4 and arranged between the inner adjusting nut 201 and the fixing bracket 1, and an outer adjusting gasket 301 sleeved on the U-shaped bolt 4 and arranged between the outer adjusting nut 202 and the fixing bracket 1.

[0037] Specifically, the gasket assembly 3 includes an inner adjusting gasket 302 and an outer adjusting gasket 301, which are respectively arranged at corresponding positions, can effectively disperse the pressure between the nut assembly 2 and the fixing bracket 1, reduce wear, enhance the stability and reliability of hose fixing, and extend the service life of the fixing structure.

[0038] In this embodiment, the fixing bracket 1 is also provided with a bracket mounting hole 101 for fixing the fixing bracket 1 on the mining dump truck.

[0039] Specifically, the number of the bracket mounting holes 101 is at least two, which are respectively opened in the areas near both ends of the fixing bracket 1, and the at least two bracket mounting holes 101 and the at least two bolt fixing holes 102 are arranged in a straight line. The at least two bracket mounting holes 101 opened on the fixing bracket 1 and arranged in a straight line with the bolt fixing holes 102 can, on the one hand, facilitate the firm installation of the fixing bracket 1 on the mining dump truck, and the multiple mounting holes improve the installation stability; on the other hand, this layout design makes the force on the fixing bracket 1 more uniform, helps to enhance the overall reliability of the hose fixing assembly, and is convenient for installation operation, thus improving the installation efficiency.

[0040] A hose fixing assembly provided by the present application forms a stable loop structure through the cooperation of the fixing bracket 1, the U-shaped bolt and the nut assembly 2, firmly fixes the hose on the mining dump truck, effectively prevents the hose from loosening and falling off due to vibration, bumping, etc. during the vehicle operation, reduces the safety risks caused by hose failures, and improves the operation safety and stability of the mining dump truck.

[0041] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
