[0001] The utility model relates to the technical field of shock absorbing mechanisms, in particular to a universal shock absorbing mechanism. Background Art

[0002] A variety of mechanical equipment are used in many engineering construction projects. Many mechanical equipment produce large vibrations when working. In order to improve the working efficiency of the equipment and the quality of the project, many equipment need to meet the requirements of simultaneous shock absorption in the horizontal and vertical directions. For example, the tamping machine in railway maintenance machinery is one of them. Its main function is to tamp the ballast, improve the density of the ballast in the roadbed, and increase the stability of the track.

[0003] When the tamping machine is working, it will generate vibration by rotating the centrifugal shaft, which makes it easier for the tamping rod of the tamping machine to be inserted into the interior of the road and then tamp the road. However, when the tamping rod vibrates, the vibration will be transmitted to the entire device, affecting the operation of the entire device. In this way, a shock-absorbing mechanism is needed to reduce the vibration of the tamping rod and reduce the transmission of the vibration of the tamping rod to the entire device.

[0004] The existing shock absorbing mechanisms all use springs for shock absorption, and their shock absorption directions are only for vertical shock absorption, and lack horizontal shock absorption. Summary of the invention

[0012] The utility model provides a universal shock absorbing mechanism. Compared with the prior art, it has the following beneficial effects:

[0013] 1. The universal shock-absorbing mechanism is provided with a first anti-collision mechanism and a second anti-collision mechanism, and the magnetic plates repel each other, so that the movable frame can be always located in the middle of the fixed frame, preventing the movable frame from horizontally moving and colliding with the fixed frame. When vibration occurs, the movable frame moves inside the fixed frame, reducing the influence of horizontal vibration on the movable block. If a violent collision occurs, the rubber block contacts the movable frame, preventing the two magnetic plates from colliding and contacting and causing the magnetic plates to break.

[0014] 2. The universal shock-absorbing mechanism, by setting a second shock-absorbing mechanism and a second anti-collision mechanism, causes the magnetic blocks to repel each other, thus making the round block away from the second fixed cylinder. When vibration occurs, the round block moves up and down, reducing the influence of the up and down vibration on the moving block. If a violent collision occurs, the fixed ring will contact the second fixed cylinder to prevent the two magnetic blocks from contacting and colliding and causing damage.
