Description
Technical Field
The utility model relates to an elevator car's buffering protection device that falls.
Background
In recent years, along with the continuous occurrence of elevator accidents, people pay more attention to safety protection devices of elevators. Especially high-rise elevator, when the car moves to higher floor, if the steel cable that pulls the car breaks, the protector that the car falls in-process generally is safety tongs, but the condition that has car guide rail fracture or safety tongs malfunctioning takes place, then the car will fall to elevator well pit with higher speed always, will lead to falling the ladder and cause serious accident. The existing elevator safety protection means are not many, so a falling buffer protection device of an elevator car needs to be designed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an elevator car's buffering protection device that falls, its is rational in infrastructure, can effectually cushion the protection to elevator car to improve the interior personnel's of elevator car security.
In order to achieve the purpose, the technical scheme of the utility model is to design a falling buffer protection device of an elevator car, which comprises an elevator shaft and the elevator car arranged in the elevator shaft; the elevator shaft is characterized in that a bearing plate is arranged at the bottom in the elevator shaft, a reinforcing plate is arranged at the bottom of the bearing plate, four spring mounting holes which are arranged in a rectangular shape are formed in the bottom wall of the elevator shaft, a first buffer spring is fixed in each spring mounting hole, and the upper end of each first buffer spring extends to the position above the corresponding spring mounting hole and is fixedly connected with the reinforcing plate; all be equipped with vertical spout in two relative lateral walls of elevartor shaft, the lower extreme of vertical spout extends to the diapire of elevartor shaft, the both ends of bearing plate are equipped with the connecting block respectively, the connecting block runs through the lateral wall of elevartor shaft and extends to in the vertical spout, be equipped with the bar hole that supplies the connecting block to run through on the lateral wall of elevartor shaft, and the lower extreme in bar hole extends to the diapire of elevartor shaft, slidable is connected with vertical slider in the vertical spout, vertical slider and connecting block fixed connection, and be connected with second buffer spring between the diapire of vertical slider and elevartor shaft.
Preferably, the bottom wall of the elevator shaft is provided with an elastic part, and the upper end of the elastic part is abutted against the center of the reinforcing plate.
Preferably, the elastic member is of an inverted U-shaped structure, and an opening of the elastic member faces downward.
Preferably, the bottom of the elevator car is provided with a supporting plate.
Preferably, the outer part of the supporting plate is covered with a rubber sleeve.
The utility model has the advantages and the beneficial effects that: the utility model provides a buffering protection device that falls of elevator car, its is rational in infrastructure, can effectually cushion the protection to elevator car to improve the interior personnel's of elevator car security.
When elevator car takes place to fall, by the cladding at the outside rubber sleeve contact bearing plate of layer board, later drive the bearing plate down, make the bearing plate drive reinforcing plate and vertical slider down to compress first buffer spring and second buffer spring, absorb the impact force that personnel received in the elevator car jointly by first buffer spring and second buffer spring, with the security that improves personnel in the elevator car. And, through setting up the elastic component, at the in-process of compressing first buffer spring, the interval between reinforcing plate and the diapire of elevartor shaft will reduce for the elastic component takes place to warp, thereby further absorbs the impact force.

Fig. 1 is a schematic diagram of the present invention.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The utility model discloses the technical scheme who specifically implements is:
as shown in fig. 1, a fall buffering protection device for an elevator car comprises an elevator shaft 1, and an elevator car 2 disposed in the elevator shaft 1; the elevator shaft is characterized in that a bearing plate 3 is arranged at the bottom in the elevator shaft 1, a reinforcing plate 4 is arranged at the bottom of the bearing plate 3, four spring mounting holes 5 which are arranged in a rectangular shape are formed in the bottom wall of the elevator shaft 1, a first buffer spring 6 is fixed in each spring mounting hole 5, and the upper end of each first buffer spring 6 extends to the position above the corresponding spring mounting hole 5 and is fixedly connected with the reinforcing plate 4; all be equipped with vertical spout 7 in two relative lateral walls of elevartor shaft 1, the lower extreme of vertical spout 7 extends to the diapire of elevartor shaft 1, the both ends of bearing plate 3 are equipped with connecting block 8 respectively, connecting block 8 runs through the lateral wall of elevartor shaft 1 and extends to in the vertical spout 7, be equipped with the bar hole 9 that supplies connecting block 8 to run through on the lateral wall of elevartor shaft 1, and the lower extreme in bar hole 9 extends to the diapire of elevartor shaft 1, slidable is connected with vertical slider 10 in the vertical spout 7, vertical slider 10 and connecting block fixed connection, and be connected with second buffering bullet 11 between the diapire of vertical slider 10 and elevartor shaft 1.
The bottom wall of the elevator shaft 1 is provided with an elastic member 12, and the upper end of the elastic member 12 abuts against the center of the reinforcing plate 4.
The elastic member 12 has an inverted U-shaped structure, and the opening of the elastic member 12 faces downward.
