DETAILED DESCRIPTION

[0022] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.

[0023] This embodiment proposes a double-layer steel wire rope shock absorber, the structure of which is as follows: Figures 1 to 3 As shown, it mainly includes a fixing seat 1, a steel wire rope 3, a top plate 4, a cover plate 5, a bidirectional threaded rod 7, a fixing assembly 9, a supporting assembly 10 and a flexible pad 11.

[0024] A top plate 4 is provided above the fixing seat 1, and the top of the top plate 4 is connected to the cover plate 5 by bolts 6 to facilitate separation of the cover plate 5 from the top plate 4. A plurality of corresponding through-wire rope holes 2 are processed on the side walls of the fixing seat 1 and the top plate 4, and a plurality of steel wire ropes 3 arranged side by side pass through the steel wire rope holes 2 on the fixing seat 1 and the top plate 4 in a circular form. The interior of the fixing seat 1 is processed with a plurality of groups of movable grooves 8 corresponding to the plurality of steel wire ropes 3, and each group of movable grooves 8 includes two symmetrically distributed fixing component mounting grooves, and a fixing component 9 is provided inside each fixing component mounting groove. The interior of the fixing seat 1 is rotatably connected to a bidirectional threaded rod 7, and the bidirectional threaded portion of the bidirectional threaded rod 7 is connected to each fixing component 9 for adjusting the distance between the two relatively arranged fixing components 9. The rear end of the bidirectional threaded rod 7 extends to the outside of the fixing seat 1 and is connected to the handle to facilitate the rotation of the bidirectional threaded rod 7.

[0025] During operation, the device is installed at the bottom of the equipment, supported by the top plate 4 and the cover plate 5, and cushioned and shock-absorbing by the wire rope 3. The distance between the symmetrically arranged fixing components 9 is adjusted by rotating the bidirectional threaded rod 7 to fix the wire rope 3, so that the fixing seat 1 can adapt to different models of wire ropes 3.

[0026] Each fixing assembly 9 comprises a movable plate 901, a connecting rod 902, and a plurality of fixing spikes 903. The movable plate 901 is slidably connected within the fixing assembly mounting slot, with its threads engaging the bidirectional threads of the bidirectionally threaded rod 7. The connecting rod 902 is fixedly attached to the top of the movable plate 901, and each connecting rod 902 is equipped with a plurality of evenly distributed fixing spikes 903, which are used to compress and secure the wire rope 3.

[0027] During operation, it is only necessary to rotate the bidirectional threaded rod 7 to drive the corresponding two movable plates 901 to move toward each other, thereby driving the connecting rod 902 to move slowly, and then driving the fixed barb 903 to move to fix the wire rope 3.

[0028] A support assembly 10 is installed between the mounting base 1 and the top plate 4 to enhance the device's support and shock absorption. This assembly comprises a middle plate 1001, a first damping spring 1002, an upper plate 1003, and a second damping spring 1004. The bottom of the middle plate 1001 is mounted above the mounting base 1 via multiple first damping springs 1002, while the upper plate 1003 is mounted above the middle plate 1001 via multiple second damping springs 1004.

[0029] During operation, the first damping spring 1002 elastically supports the middle plate 1001, and the second damping spring 1004 elastically supports the upper plate 1003 on the middle plate 1001. The double-layer elastic support method can increase the shock absorption effect. The support of the upper plate 1003 can increase the support of the top plate 4, making the support effect of this device better.

[0030] A flexible pad 11 is fixedly connected to the top of the upper plate 1003 to prevent the upper plate 1003 from making rigid contact with the top plate 4, thereby increasing the service life of the top plate 4 and the upper plate 1003, and the flexible pad 11 also has a shock-absorbing effect.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
