And only set up damping device in the bottom of car, when the actual operation, the vibration problem of the horizontal direction's that leads to the vibrations process of car upper and lower direction and the tilt and sway can't obtain solving, leads to the sedan-chair level to rock acutely, and the shock attenuation stationarity is relatively poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an elevator car damping device to solve the poor, the unable stable problem of level rocking of elevator car shock attenuation effect among the prior art.
In order to solve the problem, the utility model relates to an elevator car damping device adopts following technical scheme:
an elevator car damping device comprises a car and a car frame arranged outside the car, wherein a bottom damping structure is arranged between the bottom side of the car and the car frame, a top damping structure is arranged between the top side of the car and the car frame, a side damping structure is arranged between the side wall of the car and the car frame, the bottom damping structure and the top damping structure both comprise a supporting cylinder movably assembled on the inner side wall of the car frame, the elevator car damping device also comprises a guide rod arranged on the car frame and used for being matched with the supporting cylinder in an inserting way, and a damping spring sleeved on the guide rod is also arranged between the opposite end surfaces of the car frame and the car in a jacking way; the side shock-absorbing structure includes along the upper and lower direction assembly supporting shaft on the medial surface of car frame, be equipped with two movable sleeves along upper and lower direction spacer sleeve on the supporting shaft, the top is equipped with the side spring between movable sleeve and the supporting shaft approach to the end, and two movable sleeves all articulate there is the connecting rod, two connecting rods all with the car is articulated to be connected.
Furthermore, guide rails extending in the left-right direction are uniformly arranged on the top side and the bottom side of the car frame, and the support cylinders are assembled on the guide rails in a guiding mode.
Furthermore, the top shock absorption structure and the bottom shock absorption structure are provided with at least two groups.
Furthermore, two connecting rods in the same side damping structure are hinged to each other and then connected to the car.
The utility model has the advantages as follows: compared with the prior art, the utility model relates to an elevator car damping device, when the operation of reality, top shock-absorbing structure and end shock-absorbing structure combined action all have certain buffering space upwards and downwards to the car, have reduced the uncomfortable sense that sudden stop brought, and the shock attenuation effect is better moreover. Further, set up side shock-absorbing structure, with a supporting barrel swing joint on the car frame, except that the shock attenuation range of the upper and lower direction of car is strengthened through connecting rod and side spring, simultaneously can also be reasonable realize the damping effect of horizontal side direction car frame to the car, if car level beat, then receive side shock-absorbing structure's effect, the beat range reduces by a wide margin, has also improved the stability of buffering simultaneously, simple structure, and the actual experience effect is better moreover.

Detailed Description
In order to make the technical purpose, technical solution and advantageous effects of the present invention clearer, the technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
The utility model relates to an elevator car damping device's concrete embodiment, as shown in fig. 1, elevator car damping device includes car 1 and sets up the car frame 2 in the car 1 outside, and wherein the structure of car frame 2 and car 1 is unanimous basically with the structure of car frame 2 among the prior art and car 1, does not do the detailed description.
A bottom damping structure 3 is arranged between the bottom side of the cage 1 and the cage frame 2, a top damping structure 4 is arranged between the top side of the cage 1 and the cage frame 2, a side damping structure 5 is arranged between the side wall of the cage 1 and the cage frame 2,
wherein, to end shock-absorbing structure 3 and top shock-absorbing structure 4, the two structures are unanimous, and each other are the mirror image to arrange to end shock-absorbing structure 3 is the example, and end shock-absorbing structure 3 includes a supporting barrel 6 of movable assembly on the inside wall of car frame 2, still including setting up being used for on car frame 2 with supporting barrel 6 plug bush complex guide bar 7, still the top is equipped with the cover and is established damping spring 8 on guide bar 7 between the relative terminal surface of car frame 2 and car 1. Specifically, the guide rails 9 extending in the left-right direction are arranged on the bottom side of the car frame 2, and the support cylinder 6 is assembled on the guide rails 9 in a guiding manner, so that the movable assembly of the support cylinder 6 on the car frame 2 is realized, and the arrangement mode can meet the damping effect of the car 1 in the up-down direction.
Furthermore, the bottom damping structure 3 and the top damping structure 4 are respectively provided with two groups, and are respectively and uniformly distributed between the car frame 2 and the car 1 at intervals along the left-right direction.
For side shock-absorbing structure 5, side shock-absorbing structure 5 includes along upper and lower direction assembly support shaft 10 on the medial surface of car frame 2, be equipped with two movable sleeves 11 along upper and lower direction spacer sleeve on the support shaft 10, the top is equipped with side spring 12 between the end that movable sleeve 11 and support shaft 10 are close to, all articulates on two movable sleeves 11 has connecting rod 13, two connecting rods 13 all with car 1 is articulated to be connected.
Wherein, two connecting rods 13 in the same side damping structure 5 are hinged with each other and then connected to the car 1.
In actual operation, when the elevator car 1 stops running, the top damping structure 4 and the bottom damping structure 3 ensure a certain buffer space between the car 1 and the car frame 2 through the cooperation of the damping spring 8 and the guide rod 7. Meanwhile, the shaking caused by sudden stop of the car 1 is absorbed by the damping effect of the side damping structure 5, so that the transverse deflection of the car 1 is greatly relieved, and meanwhile, the side damping structure 5 can further enhance the buffering in the vertical direction.
Of course, in other embodiments, the support tube 6 may also be directly placed in a groove formed in the sidewall of the car frame 2, and the movable assembly is achieved by limiting to prevent the support tube 6 from being removed.
Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating but not limiting the technical solution of the present invention, and any equivalent replacement and modification or partial replacement which do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
