AI Technical Summary

Technical Problem

The existing safety fence assembly and disassembly process of lifting operations consumes a lot of manpower and labor hours, has a high labor intensity, and reduces the efficiency of lifting operations.

Method used

A lifting operation safety protection device is designed including at least three monitoring stations placed on the ground. The monitoring station includes a detector, a warning and a controller. The adjacent detectors form an electromagnetic boundary to form a closed area. The lifting machinery is arranged in the closed area. When a person or an animal enters the closed area, the detector generates a signal and the controller triggers the alarm to issue a warning.

Benefits of technology

The layout and removal process of the monitoring station is fast, the labor intensity is low, and it can automatically alarm, which improves the safety and efficiency of lifting operations and avoids the occurrence of safety accidents.

Abstract

The utility model relates to a safety protection device for hoisting operation, and relates to the technical field of hoisting operation. The hoisting operation safety protection device comprises at least three monitoring stations placed on the ground, each monitoring station comprises a detector, a warning indicator and a controller, the detectors and the warning indicators are all connected with the controllers, the detectors on every two adjacent monitoring stations jointly form an electromagnetic boundary, and the detectors on every two adjacent monitoring stations form an electromagnetic boundary. All the monitoring stations are located at the vertexes of the same polygon so that the multiple electromagnetic boundaries can jointly define a closed area, and the hoisting machinery is arranged in the closed area. The detectors on the two adjacent monitoring stations jointly construct an electromagnetic boundary, a closed area for operation of the hoisting machinery can be formed only by placing at least three monitoring stations, when people or animals enter the closed area from the outside of the closed area, the people or animals pass through the electromagnetic boundary, the detectors generate corresponding signals, and the warning indicator gives out a warning immediately. Therefore, operators of the hoisting machinery can take measures in time, and safety accidents are avoided.
