[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] The preferred embodiment of the buffer pile for elevator provided by the present utility model is as Figures 1 to 5 shown: A buffer pile for elevator includes a bottom plate 1. An installation groove 2 is opened at the top of the bottom plate 1. A vertical pipe 3 is fixedly connected to the top of the bottom plate 1. A buffer groove 4 is opened on the outer wall of the vertical pipe 3. A shock absorber 5 is fixedly connected to the inner wall of the vertical pipe 3. A shock-absorbing spring 6 is movably connected to the outer wall of the shock absorber 5.

[0028] One end of the shock absorber 5 is fixedly connected with a connecting block 7. The outer wall of the connecting block 7 is fixedly connected with a connecting frame 8. One end of the connecting frame 8 is fixedly connected with a movable ring 9. The top of the bottom plate 1 is fixedly connected with a force dividing column 10. The outer wall of the force dividing column 10 is movably connected with a lower spring 11 and an upper spring 12 respectively. It can bear most of the pressure through the cooperation of the shock absorber 5 and the shock absorption spring 6 during buffering. And the connecting frame 8 arranged outside the connecting block 7 will make the movable ring 9 move outside the force dividing column 10 when being squeezed downward, and squeeze the lower spring 11, so as to disperse the main pressure and bear the buffering pressure, reduce the stress degree of the shock absorber 5, and thus improve the use effect of the buffer column.

[0029] In this embodiment, the top of the connecting block 7 is movably connected with an adjusting tube 13. The inner wall of the adjusting tube 13 is movably connected with an adjusting rod 14. One end of the adjusting tube 13 is fixedly connected with a contact plate 15. Before the buffer column buffers the pressure, the adjusting tube 13 can be rotated according to the support height used, so that it rotates and moves outside the adjusting rod 14, thereby adjusting the lengths of the adjusting tube 13 and the adjusting rod 14, and enabling the contact plate 15 to be adjusted to a suitable height, effectively improving the functionality of use and meeting different use requirements.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, the preferred embodiment of the elevator buffer pile provided by the present utility model is as Figures 1 to 5 shown: The top of the contact plate 15 is fixedly connected with a protective pad 16, and the protective pad 16 is a thickened rubber protective pad. When buffering, the protective pad 16 arranged on the contact plate 15 can start to receive the pressure from the top to achieve the effect of impact pressure.

[0032] In this embodiment, one end of the lower spring 11 and one end of the upper spring 12 are both fixedly connected with the movable ring 9. The inner wall of the movable ring 9 is movably connected with the outer wall of the force dividing column 10. The movable ring 9 will move outside the force dividing column 10 when the adjusting rod 14 buffers downward, and squeeze and deform the lower spring 11, so that it can dissolve a part of the pressure.

[0033] Furthermore, threads are provided on the inner wall of the adjusting tube 13 and the outer wall of the adjusting rod 14, and the adjusting tube 13 is threadedly connected with the adjusting rod 14, which is convenient for adjusting the support height of the contact plate 15 and disassembling and assembling it, so as to meet different use requirements.

[0034] Furthermore, the vertical tube 3 is movably connected with the connecting frame 8 through a buffer groove 4, and the diameter of the buffer groove 4 is larger than the diameter of the connecting frame 8. The number of the connecting frames 8 is three, and the three connecting frames 8 are arranged in a ring on the outer wall of the connecting block 7. When the connecting frame 8 buffers the pressure downward, it can enter the buffer groove 4, so that the movable ring 9 can move outside the force dividing column 10 and buffer a part of the pressure.

[0035] In addition, mounting blocks are provided at both ends of the force-sharing column 10, and the two mounting blocks are fixedly connected to the upper spring 12 and the lower spring 11 respectively, which can position and install the upper and lower springs, so that they can be used to buffer pressure normally.

[0036] When in use, during buffering, the protective pad 16 provided on the contact plate 15 can start to receive the pressure from the top, and then transfer it to the adjusting pipe 13 and the adjusting rod 14 to compress and deform the shock absorber 5 and the shock-absorbing spring 6, so as to dissolve most of the pressure. At the same time, the connecting frame 8 and the movable ring 9 provided outside the connecting block 7 will move outside the force-sharing column 10 while the adjusting rod 14 moves downward for buffering, and extrude and deform the lower spring 11, so that it can dissolve a part of the pressure. In this way, the shock absorber 5 and the force-sharing column 10 can dissolve all the pressure. At the same time, rotating the adjusting pipe 13 can adjust the support height of the contact plate 15, so that the buffering distance from the ground can be adjusted during buffering, and it is convenient to disassemble and repair the contact plate 15, so as to meet different usage requirements.

[0037] In summary, for this elevator buffer pile, during buffering, most of the pressure can be borne through the cooperation of the shock absorber 5 and the shock-absorbing spring 6. And when the connecting frame 8 provided outside the connecting block 7 is squeezed downward, the movable ring 9 will move outside the force-sharing column 10 and extrude the lower spring 11, so that the main pressure can be dispersed and the buffering pressure can be borne, reducing the stress on the shock absorber 5. At the same time, before the buffer column buffers the pressure, the adjusting pipe 13 can be rotated according to the required support height, so that it rotates and moves outside the adjusting rod 14, thereby adjusting the lengths of the adjusting pipe 13 and the adjusting rod 14, and enabling the contact plate 15 to be adjusted to a suitable height, effectively improving the functionality of the use.
