[0032] In actual use, by setting the buffer assembly and the damping assembly, the damping effect of the elevator can be effectively improved, the vibration generated during use is reduced, and the comfort of passengers is improved.

[0033] Specifically, the telescopic columns 2300 are arranged in an array and uniformly spaced between the first damping plate 2100 and the second damping plate 2200, and the telescopic column 2300 can be a hydraulic cylinder or a gas cylinder structure commonly used in the prior art, and the specific structure and principle will not be described here; the first damping plate 2100 and the second damping plate 2200 are both made of rubber material, and the top of the first damping plate 2100 has an anti-skid pattern (not shown in the figure). Specifically, by arranging two damping plates made of rubber material and a plurality of telescopic columns 2300 between the two damping plates, the outside of the telescopic column 2300 is connected with the first elastic member 2400, the telescopic column 2300 plays a main supporting and buffering role, and the first elastic member 2400 deforms along with the telescopic column 2300, thereby buffering and dispersing the impact force generated by the vibration to the rubber plate to reduce the impact force and play a buffering effect, effectively reducing the discomfort of passengers caused by vibration.

[0034] And the mounting head 4000 is connected with the traction machine, and when the traction machine starts and stops, the damping seat can absorb and reduce the vibration caused by the start and stop of the traction machine, thereby reducing the discomfort of passengers caused by vibration.

[0035] In some embodiments of the utility model, it can also have the following additional technical features: the damping seat comprises a fixed bottom plate 3200 connected to the bottom of the connecting column 3100, and a plurality of shock absorbers 3300 connected to the fixed bottom plate 3200, and the shock absorber 3300 is connected with the top inner wall of the partition layer 1100.

[0037] In some embodiments of the utility model, it can also have the following additional technical features: the shock absorber 3300 body further comprises a second buffer cavity 3340 of an annular structure, and the second buffer cavity 3340 is connected around the outer periphery of the first buffer cavity 3310 and communicates with the first buffer cavity 3310.

[0038] In some specific embodiments of the utility model, it can further have the following additional technical features: a plurality of through holes 3312 are sequentially arranged on the circumferential side wall of the first buffer cavity 3310 from top to bottom, and the hole diameter of the plurality of through holes 3312 gradually increases from the bottom of the first buffer cavity 3310 to the notch 3311 of the first buffer cavity 3310.

[0039] Specifically, through the above-mentioned setting of the hole diameter of the through hole 3312, when the support rod 3320 suddenly moves downward, the sealing piston 3321 will gradually block part of the through hole 3312, thereby gradually reducing the total flow of each through hole 3312, so that the buffer force generated during the movement of the support rod 3320 to the bottom of the first buffer cavity 3310 gradually increases, thereby effectively absorbing the instantaneous vibration during start and stop.

[0040] In some specific embodiments of the utility model, it can further have the following additional technical features: when the sealing piston 3321 is at the lowest point, the highest point of the sealing piston 3321 is higher than the uppermost through hole 3312.

[0041] In some specific embodiments of the utility model, it can further have the following additional technical features: the second buffer cavity 3340 is connected with an annular partition plate 3350, the annular partition plate 3350 and the top of the second buffer cavity 3340 are connected with a third elastic member 3360, and the annular partition plate 3350 and the top of the second buffer cavity 3340 are filled with a second buffer medium (not shown in the figure).

[0042] It should be noted that the first buffer medium and the second buffer medium can be the same buffer medium or different buffer media, which can be air or water or oil or a mixture of water and oil or other gelatinous mixtures, which are not limited here; the first elastic member 2400, the second elastic member 3330 and the third elastic member 3360 are all springs.

[0043] In some embodiments of the utility model, it can further have the following additional technical features: the annular partition plate 3350 is provided with a flow hole 33513312. At this time, the first buffer medium and the second buffer medium are the same buffer medium. Due to the existence of the annular partition plate 3350, the second buffer cavity 3340 is sequentially separated from top to bottom to form an upper buffer cavity (not shown in the figure) and a lower buffer cavity (not shown in the figure), and the third elastic member 3360 is located in the upper buffer cavity. By arranging the flow hole 33513312, when the sealing piston 3321 moves, the first buffer medium and the second buffer medium flow. When the sealing piston 3321 moves downward and extrudes the buffer medium, part of the buffer medium impacts on the annular partition plate 3350 and promotes the annular partition plate 3350 to move upward by the pressure acting on the bottom of the annular partition plate 3350, and part of the buffer medium passes through the flow hole 33513312 to reach the upper buffer cavity, thereby increasing the amount of buffer medium in the upper buffer cavity and improving the force resisting the movement of the annular partition plate 3350, so as to reduce the instantaneous impact force and make the overall change tend to be gentle. When the sealing piston 3321 moves upward and drives the buffer medium to move, correspondingly, the overall structure with the upper buffer medium will also generate a corresponding resistance to reduce the overall instantaneous impact force, thereby effectively reducing the shock.

[0044] In some embodiments of the utility model, it can further have the following additional technical features: the connecting column 3100 is movably sleeved with a disperser 3400 in the circumferential direction, and the top of the supporting rod 3320 is connected with the top inner wall of the partition layer 1100 through the disperser 3400.

[0045] In some embodiments of the utility model, it can further have the following additional technical features: the disperser 3400 comprises a first circular table 3410 and a second circular table 3420, one side of the first circular table 3410 with a larger diameter is provided with an opening and connected with the top inner wall of the partition layer 1100, the other side of the first circular table 3410 with a smaller diameter is connected with the top of the supporting rod 3320 of the plurality of shock absorbers 3300, the second circular table 3420 is connected in the first circular table 3410 through the opening, and one side of the second circular table 3420 with a larger diameter is connected with one side of the first circular table 3410 with a larger diameter, and the other side of the second circular table 3420 with a smaller diameter is connected with the top inner wall of the partition layer 1100.

[0046] The various circular tables of the disperser 3400 have inclined surface structures, so that the force transmission is not straight up and down, thereby being more effectively dispersed to the top plate of the entire partition layer 1100, and the overall durability is increased.

[0047] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
