Abstract
The utility model relates to an incontrollably bottoming damping device for an electric elevator, which comprises a circle casing which is fixed on an upper cover of a steel board which is arranged at the bottom end of an electric elevator box, the steel board circle casing is filled up with rubber balls as a container of hollow rubber balls; circle holes are arranged at the bottom end of the circle casing, and convex blocks in a bottom pit are inserted in circle holes; the bottom part in the steel board circle casing is also provided with a base which can move up and down; the base can block hollow rubber balls from scattering, when safety system of the electric elevator has a fault, the box falls down, the base can crash with convex blocks in the bottom pit to creep hollow rubber balls and obtain soft landing of the box. The utility model has the advantages of simple structure, high reliability, and convenient installation. The utility model can be used when matching with an original mechanical buffer.
Description
The utility model relates to a kind of elevator car safety, particularly elevator pier bottom buffering device.
Along with the fast development of China's skyscraper, elevator more and more is widely used as the actv. means of delivery.But the elevator safety accident happened occasionally in the last few years; its major cause is that existing elevator end of a year or month shock absorber design is unreasonable; existing elevator end of a year or month shock absorber is arranged on the mechanical damping device of pit; in case elevator safety system is malfunctioning; cab just falls at a high speed and energy disperser forms mechanical collision; the cushioning effect of this energy disperser is very limited, can not play the effect of actv. safety guard-safeguard.
The purpose of this utility model provides a kind of elevator pier bottom buffering device, and it can make cab form soft landing when elevator safety system is malfunctioning, prevents the generation of bump accident.
The purpose of this utility model is to realize like this, fix a round shell of steel plate at the steel plate loam cake of elevator bridge case bottom, the round shell of this steel plate fills up the hollow rubber ball as container in it, its bottom has a circular hole that can insert the pit projection, bottom in the round shell of steel plate also is provided with a mobile base, so as when contact pit projection the extruded hollow rubber sphere.The utility model utilizes the buffer action of hollow rubber ball, realizes the soft landing of cab, avoids the generation of bump accident.
The utility model is simple in structure, good damping result, simple installation, can with the supporting use of the energy disperser of former elevator, can improve the safety performance of elevator greatly.
Fig. 1 is a structural representation of the present utility model.
The utility model will be further described below in conjunction with accompanying drawing.
The utility model comprises a round shell of fixing at the steel plate loam cake 2 of elevator cage bottom 4 of steel plate, the round shell 4 of this steel plate is as the container of hollow rubber ball 3, fill up hollow rubber ball 3 within it, have circular hole 6 in its bottom, this circular hole 6 can insert the projection 7 of pit, the center of the center of circular hole 6 and projection 7 is in same line of centers, but the bottom in the round shell 4 of steel plate also is provided with the base 5 of a up-and-down movement, block hollow rubber ball 3 makes its unlikely being scattered to this base 5 on the one hand, when falling, the malfunctioning cab of elevator safety system collides with extruded hollow rubber sphere 3 on the other hand with the projection 7 of pit, elastic reaction buffering collision of closed by rubber sphere makes the cab soft landing.The projection 7 of pit can be the projection of former mechanical damping device, and the upper end of the round shell 4 of steel plate is fixing with steel plate loam cake 2 by bolt 1.
