Description

An elevator shaft with fall protection

technical field

The utility model relates to the technical field of elevator safety devices, in particular to an elevator shaft with fall protection.

Background technique

With the increase of high-rise buildings, the use of elevators increases thereupon. In order to ensure the safety of elevator operation, an elevator anti-fall protection device must be assembled. Nowadays, elevator fall prevention is mainly realized by devices such as speed governor, safety gear and buffer spring at the bottom of the hoistway. When the running speed of the elevator reaches or exceeds the set limit value, the speed limiter stops running, and lifts the connecting rod mechanism installed on the car beam with the help of the friction force in the sheave or the rope clamping mechanism, and through mechanical action Send a signal, cut off the control circuit, and force the safety gear to act at the same time, so that the car is forced to stop on the guide rail. Only when all safety switches are reset and the car is lifted upwards, the safety gear can be released. When the safety gear does not return to the normal state , the elevator cannot be used. The buffer spring device at the bottom of the hoistway can reduce the impact force of the elevator hitting the ground when it falls, but the effect is limited. Although the elevator is equipped with the above two anti-fall protection devices, it still cannot completely avoid the occurrence of elevator falling accidents. There are three reasons: 1. The elevator is overloaded; 3. The elevator wire rope falls off or breaks. For this purpose, we propose an elevator shaft with fall protection.

Utility model content

The purpose of the utility model is to solve the above defects and provide an elevator shaft with fall protection, which can effectively solve the problems in the background technology.

The purpose of this utility model is achieved in the following ways:

An elevator shaft with fall protection, comprising a shaft, the inner lower end of the shaft is provided with a pit, the interior of the shaft is provided with a buffer protection pad, there is a gap between the shaft and the buffer protection pad, and the buffer protection pad The lower end is provided with a telescopic support column, and the surface of the telescopic support column is provided with a buffer spring. The inner wall of the well is provided with a deceleration rack. An elevator main body is provided, a speed sensor is provided on the surface of the elevator main body, a ratchet is provided at the upper and lower ends of the elevator main body, and a deceleration shaft is provided inside the ratchet.

In the above description, as a preferred solution, the buffer protection pad is fixedly connected to the telescopic support column.

In the above description, as a preferred solution, the elevator body and the ratchet are fixedly connected through a deceleration shaft.

In the above description, as a preferred solution, the buffer protection pad is made of rubber.

The beneficial effects produced by the utility model: compared with the prior art, this kind of elevator shaft with fall protection senses the falling speed of the car through the speed sensor provided, and sends the deceleration information to the deceleration shaft and deceleration shaft when a failure occurs. The ratchet decelerates on the fixed rack on the elevator shaft track through the ratchet, and then locks the car on the elevator shaft track to avoid accidents, thereby achieving the role of safety protection. When the car reaches the bottom, it passes through the buffer provided. The protective pad and buffer spring provide multiple buffers to avoid casualties caused by excessive impact.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

In this embodiment, referring to Figures 1 to 3, an elevator shaft with fall protection in this solution includes a shaft 1, a pit 3 is provided at the lower end of the shaft 1, and a buffer protection is provided inside the shaft 3. Pad 4, there is a gap between the shaft 1 and the buffer protection pad 4, the lower end of the buffer protection pad 4 is provided with a telescopic support column 5, the surface of the telescopic support column 5 is provided with a buffer spring 6, and the inner wall of the shaft 1 A deceleration rack 9 is provided, and the deceleration racks 9 are provided with several, and are evenly distributed on the inner wall of the hoistway 1. The inside of the hoistway 1 is provided with an elevator main body 2, and the surface of the elevator main body 2 is provided with a speed sensor 8. The upper and lower ends of the elevator main body 2 are provided with a ratchet 7, and the ratchet 7 is provided with a decelerating shaft 10 inside.

This embodiment senses the falling speed of the car through the speed sensor provided, and sends the deceleration information to the deceleration shaft and the deceleration ratchet when a failure occurs, and the ratchet decelerates on the fixed rack provided on the elevator shaft track, and then the car is decelerated. It is locked on the track of the elevator shaft to avoid accidents and thus achieve the function of safety protection. When the car reaches the bottom, the buffer protection pad and buffer spring are provided for multiple buffers to avoid casualties caused by excessive impact.

In addition, the buffer protection pad 4 is fixedly connected with the telescopic support column 5 . The main body 2 of the elevator is fixedly connected with the ratchet 7 through a reduction shaft 10 . The buffer protection pad 4 is made of rubber.

It should be noted that the utility model is an elevator shaft with fall protection. When working, when the elevator fails and falls, the speed sensor 8 senses the falling speed of the car, and then sends the deceleration information to the deceleration shaft 10 and the ratchet 7 , decelerate on the deceleration rack 9 that is provided with on the track of elevator shaft inner side wall by ratchet 7, and then elevator main body 2 is locked on the elevator shaft track. If drop to the bottom, the car can also be cushioned and shock-absorbed by the buffering protective pad 4 and the buffer spring 6, so as to reach the safety of protecting the personnel inside the car.

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions.
