Description

Buffer device for shallow pit

Technical Field

The utility model relates to an elevator equipment technical field specifically is a buffer device for shallow pit.

Background

According to the national standard GB/T21739-2008 home elevator manufacturing and installation scope, under the condition that no mechanical stopping device is installed, the following requirements must be met: 1. the distance between the lowest part at the bottom of the lift car and the pit surface is not less than 0.1 m; 2. The vertical distance between the highest part in the vertical projection bottom range of the car and the lowest part (except the toe guard and the guide shoe) of the car is not less than 0.3 m. Generally, the pit size limiting component is the above point 2. At present, polyurethane buffers which are easy to age and unstable in performance are gradually eliminated, hydraulic buffers are widely used on villa ladders by virtue of high-efficiency and stable performance, but most of the buffers in the market are suitable for villa ladder buffers, the free height of each buffer is 0.3m, the height of each buffer is too high, and the buffers cannot be applied to elevators with low pits.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a to current buffer height among the prior art too high, can not be applied to the problem in the elevator of low pit, provide the buffer device that is used for shallow pit now, satisfying national standard's requirement under, can reduce the pit degree of depth to reduce use cost.

The utility model provides a buffer device for shallow pit, including sedan-chair frame, sedan-chair frame includes the underbeam, found the roof beam immediately, found the roof beam and fix the both ends at the underbeam immediately, wherein at least one found the curb girder side and is close to the fixed buffer board that is equipped with of underbeam, be equipped with the buffer of fixing at the pit under the buffer board, the buffer board lower extreme is less than buffer compression state's minimum height to the distance of underbeam.

Preferably, the buffer plate comprises a fixing plate, a bottom plate and a reinforcing plate, the fixing plate is fixedly connected with the vertical side beam through a fastener, the bottom plate is vertically arranged on the vertical side beam horizontally, the bottom plate is fixedly connected with the fixing plate through the reinforcing plate, and the reinforcing plate is perpendicular to the fixing plate and the bottom plate.

Preferably, the fixing plate, the bottom plate and the reinforcing plate are integrally formed or connected by fasteners or welded.

Preferably, the buffer is located directly below the bottom plate.

Preferably, the buffer is a hydraulic buffer.

The utility model has the advantages that: through this buffer device, required space when can reducing the installation elevator, can be with the height that reduces the pit to can reduce construction cost, buffer device simple structure, simple to operate.

Drawings

FIG. 1 is a schematic structural view of the installation of the buffer plate and the buffer according to the present invention;

the device comprises a lower beam 1, a lower beam 2, a vertical measuring beam 3, a buffer plate 31, a fixing plate 32, a reinforcing plate 33, a bottom plate 4 and a buffer.

Detailed Description

The technical solution of the present invention is described below, without limitation, with reference to the accompanying drawings, for the purpose of better understanding the technical contents by the public.

Examples

As shown in fig. 1, a buffer device for shallow pit comprises a car frame, wherein the car frame comprises a lower beam 1 and vertical measuring beams, the vertical measuring beams are fixed at two ends of the lower beam 1, a buffer plate 3 is fixedly arranged on the side surface of at least one vertical side beam 2 close to the lower beam 1, a buffer 4 fixed in the pit is arranged under the buffer plate 3, and the distance from the lowest end of the buffer plate 3 to the lower beam 1 is smaller than the minimum height of the buffer 4 in a compression state.

Wherein, buffer board 3 includes fixed plate 31, bottom plate 33, reinforcing plate 32, and fixed plate 31 passes through fastener and 2 fixed connection of standing the curb girder, and bottom plate 33 is stood upright survey roof beam level and is placed, through reinforcing plate 32 fixed connection between bottom plate 33 and the fixed plate 31, reinforcing plate 32 perpendicular to fixed plate 31 and bottom plate 33, and buffer 4 installs under bottom plate 33, can integrated into one piece or connect or weld through the fastener to fixed plate 31, bottom plate 33, reinforcing plate 32, in this embodiment, connect fixedly through the fastener between fixed plate 31, bottom plate 33 and the reinforcing plate 32, through bottom plate 33, mutual fixity between fixed plate 31 and the reinforcing plate 32 three, at the in-process of bottom plate 33 and the contact of buffer 4, reinforcing plate 32 can increase the atress degree of bottom plate 33, avoids buffer board 3 to take place to warp.

Specifically, in the descending process of the elevator, the lower beam 1 firstly reaches the position of the buffer 4, the buffer 4 is staggered with the lower beam 1, at the moment, the buffer 4 cannot be in contact with the lower beam 1, the elevator continues to move downwards until the bottom plate 33 of the buffer plate 3 fixed on the side face of the vertical side beam 2 is in contact with the buffer 4, at the moment, the bottom plate 33 continues to move downwards, under the action of the buffer 4, the speed of the car frame and the elevator can be reduced, the elevator car and the car frame are prevented from directly impacting a pit, and the safety of passengers and equipment is protected.

It should be understood that the above-mentioned description including the accompanying drawings is not intended to limit the technical solutions, and in fact, modifications to the technical solutions, including shapes of structures of various parts, dimensions, materials used, and equivalents of substantially the same functional structures, are within the technical solutions claimed in the present invention under the same or similar principles.
