Safety protection device for elevator in intelligent community

Abstract

The invention relates to a safety protection device for an elevator in an intelligent community. The safety protection device comprises an elevator cage, an elevator shaft, a connecting frame plate, adriven wheel, a dragging steel wire rope, a dragging wheel, a counter weight and a bearing transverse plate. The bearing transverse plate is fixedly arranged in the elevator shaft. The elevator cageis arranged in the elevator shaft. The two ends of the dragging steel wire rope are connected to the lower end face of the bearing transverse plate and the upper end face of the counter weight correspondingly. The dragging steel wire rope is sequentially wound around the driven wheel and the dragging wheel. According to the safety protection device, an existing car platform sill elevator is improved, protecting assemblies are arranged on the top, the bottom and the side portion of a car platform sill, in this way, after the dragging steel wire rope breaks, falling of the car platform sill canbe avoided, safety risks can be avoided effectively, therefore, by means of improvement, in the using process of the elevator of the intelligent community, safety is improved greatly, and thus the device meets the market requirement better.

Description

technical field [0001] The invention relates to the technical field of smart community equipment, in particular to a safety protection device for elevators in a smart community. Background technique [0002] With the rapid development of the economy and the continuous deepening of the urbanization process, the number of high-rise buildings in my country has increased year by year, and elevators have become an essential tool for carrying people and goods in high-rise buildings. The basic principle of the car elevator is traction drive, the car and the counterweight are connected by a traction wire rope, the traction wire rope is hung on the traction wheel, and the traction wheel is dragged by the traction motor, so that The traction wire rope moves under the action of friction, and then drives the car up and down. In order to ensure that the elevator can level the floor accurately and stop reliably, the elevator is also equipped with a brake system, which makes the car stop ...

AI Technical Summary

Problems solved by technology

After the elevator has been used for a long time, due to mechanical wear and other reasons, the traction wire rope and traction sheave will wear to varying degrees, resulting in weakened traction force, and the wear between the brake shoe and the hub will lead to a decrease in braking force

In actual use, as the wear of the traction wire rope intensifies and the load is too heavy, it is easy to break the traction wire rope when the car is lifted up, so that the car will also fall
