Abstract

The utility model discloses a novel lift vibration attenuation cushion and relates to the field of vibration attenuation cushions. The lift vibration attenuation cushion is good in deflection performance and resistant to wearing. The lift vibration attenuation cushion comprises an upper cushion plate, a lower cushion plate and a vibration attenuation layer arranged between the upper cushion plate and the lower cushion plate. The lift vibration attenuation cushion is characterized in that the vibration attenuation layer is made of a thermoplastic polyurethane elastic body. At least one annular groove is formed in a side wall of the vibration attenuation layer. The lift vibration attenuation cushion has the advantages that the vibration attenuation layer is made of the thermoplastic polyurethane elastic body and is good in the vibration attenuation effect; the wearing-resistant performance of the vibration attenuation layer is obviously enhanced; at least one annular groove is formed in the side wall of the vibration attenuation layer, so that space of materials is enlarged when the vibration attenuation layer is pressed, tearing caused by extruding is avoided, stress concentration is eliminated and the deflection performance is good.

Description

Novel elevator cushion blocking

Technical field

The utility model relates to cushion blocking field, is specifically related to a kind of elevator shock-absorbing pad.

Background technology

In recent years, the big or middle urban development of China was rapid, and the high building of various places is rised sheer from level ground, and when building high building throughout the country, the elevator industry of China is flourish, and elevator output increases substantially.When elevator industry is flourish, elevator shock-absorbing field also progressively grows up, and wherein most typical is elevator shock-absorbing pad.Existing elevator shock-absorbing pad is comprised of rubber block and the backing plate that is connected in rubber block two ends, and rubber block generally adopts natural rubber, during use, meets the damping load bearing requirements of different size elevator by the quantity of increase and decrease cushion blocking.The flexibility of material of this kind of elevator shock-absorbing pad own is bad, not wear-resisting, lancinating is poor and cause the life-span shorter.Most of elevator shock-absorbing pads are because standing not lifted load impacts, and rubber is torn while being impacted under crunch, also have plenty of serious aging be full of cracks after use, so need improve at the material of elevator shock-absorbing pad and the configuration aspects of cushion blocking.

Summary of the invention

The novel elevator cushion blocking that provides a kind of flexibility good, wear-resisting is provided the purpose of this utility model.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A novel elevator cushion blocking, comprises upper padding plate, lower bolster, the buffer layer between upper padding plate and lower bolster, it is characterized in that: buffer layer is made by TPUE, offers at least one annular groove on the sidewall of buffer layer.

Further, be provided with at least two through holes in buffer layer, be provided with damping hydraulic cylinder, be arranged on the damping piston in damping hydraulic cylinder in through hole, damping hydraulic cylinder is fixedly connected with lower bolster.

Further, in buffer layer, evenly embed at least two damping springs.

Further, the outer rim of buffer layer and through hole are fillet structure.

The beneficial effects of the utility model are:

1, buffer layer adopts TPUE to make, and its resistance to abrasion significantly strengthens, good damping effect; On the sidewall of buffer layer, offer at least one annular groove, buffer layer material self space when pressurized is increased, avoid, because of tearing that extruding causes, eliminating stress concentrated, flexibility is better.

2, in buffer layer, be provided with at least two through holes, in through hole, be provided with damping hydraulic cylinder and damping piston, during damping, damping piston moves back and forth in damping hydraulic cylinder, and the vibration energy that dissipates rapidly has good buffer action, alleviated vibrations, so good damping effect.

3, in buffer layer, evenly embed and have at least two damping springs, form compounded rubber spring shock-absorbing pad, in the situation that not increasing buffer layer volume and not improving buffer layer hardness, effectively increase the rigidity of cushion blocking, noise is little, and damping effect is good.

4, the outer rim of buffer layer and through hole are made as to fillet structure, have improved the antifatigue physical property of cushion blocking, improve damping capaicty and the damping effect of cushion blocking.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Wherein Reference numeral is: 1-upper padding plate, 2-buffer layer, 3-lower bolster, 4-annular groove, 5-through hole, 6-damping hydraulic cylinder, 7-damping piston, 8-damping spring, 9-fillet structure.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, a kind of novel elevator cushion blocking, comprises three-decker, upper and lower two-layer upper padding plate 1 and the lower bolster 3 of being respectively, and this upper padding plate 1 and lower bolster 3 can be made by corrosion-resistant steel or zincing steel sheet, between upper padding plate 1 and lower bolster 3, it is buffer layer 2, buffer layer 2 is made by TPUE, this TPUE is by '-diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macromolecular polyol, the High molecular material that the common reactive polymeric of chain extender forms, during its molecular structure by '-diphenylmethane diisocyanate (MDI), hard block and '-diphenylmethane diisocyanate (MDI) that toluene diisocyanate (TDI) and chain extender reaction obtain, the soft segment that toluene diisocyanate (TDI) and macromolecular polyol reaction obtain alternately forms, it is high that it has intensity, good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, the characteristics such as weather.

Buffer layer 2 is embedded in damping spring 8, TPUE forms compounded rubber spring shock-absorbing pad together with damping spring 8, in the situation that not increasing buffer layer 2 volumes and not improving buffer layer 2 hardness, effectively increase the rigidity of cushion blocking, damping effect is good.In buffer layer 2, be provided with at least two through holes 5, described through hole 5 is distributed in buffer layer 2, in the through hole 5 of buffer layer 2, be placed with damping hydraulic cylinder 6 and damping piston 7, in damping hydraulic cylinder 6, be filled with damping liquid, damping hydraulic cylinder 6 is fixedly connected with lower bolster 3, damping piston 7 is movably arranged in damping hydraulic cylinder 6, and damping piston 7 can be at the interior back and forth movement of damping hydraulic cylinder 6.During damping, damping piston 7 moves back and forth in damping hydraulic cylinder 6, and the vibration energy that dissipates rapidly has good buffer action, has alleviated vibrations, so good damping effect.

The outer rim of buffer layer 2 and through hole 5 are made as fillet structure 9, and its object has been to improve the antifatigue physical property of cushion blocking, improve damping capaicty and the damping effect of cushion blocking.On the sidewall of buffer layer 2, offer at least one annular groove 4, by annular groove 4, can make buffer layer 2 material self space when pressurized increase, avoid, because of tearing that extruding causes, eliminating stress concentrated, flexibility is better.

Certainly, the above is only better embodiment of the present utility model, and all equivalences of doing according to structure, feature and principle described in the utility model application range change or modify, and are included in the utility model patent claim.
