Description

Technical Field

[0001] The present application relates to the technical field of shock absorbing structures, and in particular to a shock absorbing structure for a bulldozer. Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] The existing bulldozer shock absorption structure is to install a shock absorption bracket under the floor frame, such as Figure 1 As shown, the shock-absorbing bracket and the floor frame are connected by a shock-absorbing seat and a shock-absorbing block. During the installation of the shock-absorbing seat, in order to ensure the stability and shock-absorbing effect of the shock-absorbing seat, the shock-absorbing seat and the thickened pad need to be placed in the shock-absorbing seat in advance, and then the shock-absorbing seat is welded and fixed on the shock-absorbing bracket. If the position deviates during the process of welding and installing the shock-absorbing seat, the mounting holes of the shock-absorbing block, the thickened pad and the shock-absorbing seat cannot be aligned, affecting the thread processing of the mounting holes, and the subsequent bolts passing through the outer shock-absorbing block, the mounting holes of the shock-absorbing seat, and the tightening installation of the shock-absorbing block and the thickened pad cannot be aligned with the mounting holes, requiring repeated corrections, increasing the workload and installation time. Therefore, a bulldozer shock-absorbing structure that does not require welding installation is needed to improve installation efficiency. Utility Model Content

The first shock-absorbing block is used to absorb the impact or vibration between the floor frame and the shock-absorbing bracket, and the bolts are tightened through the threaded holes of the second shock-absorbing block, thereby eliminating the process of welding the shock-absorbing seat, reducing the difficulty of assembly, improving the assembly efficiency, and saving the assembly cost.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0019] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1

[0020] A bulldozer shock absorbing structure, such as Figure 1As shown, it includes: a shock-absorbing bracket 2, a pressure plate 4, a shock-absorbing block, a bolt 3, and a nut 8. The shock-absorbing bracket 2 is located below the floor frame 1. Two mounting holes 6 are provided on the shock-absorbing bracket 2. A first shock-absorbing block 5 is provided between the shock-absorbing bracket 2 and the floor frame 1. A pressure plate 4 is provided between the first shock-absorbing block 5 and the bottom frame. A second shock-absorbing block 7 is provided at the end of the shock-absorbing bracket 2 away from the floor frame 1. The bolt 3 passes through the floor frame 1, the pressure plate 4, the first shock-absorbing block 5, the mounting hole 6, the second shock-absorbing block 7 in sequence, and finally the bolt 3 is fixed by the nut 8. In this way, the shock-absorbing bracket 2 can be fixed on the floor frame 1 by opening the mounting hole 6 on the shock-absorbing bracket 2, without any welding operation, thereby improving the installation efficiency. At the same time, the vibration on the floor frame 1 is damped by the first shock-absorbing block 5 and the second shock-absorbing block 7 to ensure the shock-absorbing effect.

[0021] A through hole is provided in the middle of the first damping block 5. Figure 2 As shown, a threaded hole is provided in the middle of the second shock-absorbing block 7, and the bolt 3 passes through the through hole of the first shock-absorbing block 5. The first shock-absorbing block 5 can alleviate the impact of the base frame to the shock-absorbing bracket 2, and the bolt 3 passes through the threaded hole of the second shock-absorbing block 7 to be tightened and fixed, thereby dispersing the vibration of the nut 8 on the bolt 3, and preventing the nut 8 from falling off due to the impact, which affects the fixation of the bolt 3.

[0022] A gasket 9 is provided between the shock absorbing bracket 2 and the first shock absorbing block 5 . A mounting hole 6 is provided at the center of the gasket 9 . The diameter of the gasket 9 is greater than the diameter of the first shock absorbing block 5 .

[0023] The mounting hole 6 is a threaded through hole, which is convenient for tightening and installing the bolt 3 and increases the tightening and fixing of the bolt 3 .

[0024] A pressure plate 4 is provided between the nut 8 and the second damping block 7, and the pressure plate 4 acts as a buffer between the nut 8 and the second damping block 7 to prevent the second damping block 7 from directly acting on the nut 8 and causing the nut 8 to fall off.

[0025] The first shock absorbing block 5 is a cylindrical rubber shock absorbing block, and a surface of the first shock absorbing block 5 close to the pressure plate 4 is in a truncated cone shape, so that the impact on the floor frame 1 can be buffered by the cylindrical rubber shock absorbing block.

[0026] The pressing plate 4 is a circular metal pressing plate, which can fix the first shock absorbing block 5 and the second shock absorbing block 7 on the shock absorbing bracket 2 to compress the contraction degree of the two shock absorbing blocks.

[0027] In the technical solution of the present application, the structure of the shock-absorbing seat 10 is reduced to avoid the step of welding during the installation process. In this way, there is no need to worry about the alignment of the mounting holes 6 of the shock-absorbing blocks and thick gaskets 9 in the shock-absorbing seat 10 with the mounting holes 6 of the shock-absorbing seat 10. By opening the mounting holes 6 on the shock-absorbing bracket 2, the first shock-absorbing block 5 and the second shock-absorbing block 7 are directly installed on both sides of the mounting holes 6 of the shock-absorbing bracket 2, and the two shock-absorbing blocks are fixed by bolts 3 and nuts 8. In this way, the first shock-absorbing block 5 is used to absorb the impact or vibration between the floor frame 1 and the shock-absorbing bracket 2, and the shock-absorbing bracket 2 is used as a whole to absorb the shock. The bolt 3 is tightened through the threaded hole of the second shock-absorbing block 7, and the protective nut 8 is further detached from the bolt 3, thereby improving the installation and tightening effect. In this process, since the welding process is omitted, the assembly difficulty is reduced, the assembly efficiency is improved, and the assembly cost is saved.

[0028] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
