Special electrical control box with security monitoring function for lifting equipment

Abstract

The invention relates to a special electrical control box with security monitoring function for lifting equipment, which is formed by connecting an electrical control box and a handle control box; the electrical control box of the special electrical control box is connected with a security monitoring device; the circuit of the special electrical control box is composed of a CPU, a data acquisition module, a driver module, a relay switch and a stabilized voltage supply module; a power supply input port of the CPU is connected with an output port of the stabilized voltage supply module; the CPUis connected with an output port of the data acquisition module by an I / O port and is connected with an input port of the driver module by an output port; an output port of the driver module is connected with the relay switch; and the relay switch is connected with the electrical control box. The invention can effectively monitor the operation status of the lifting equipment, thus improving the operation security of the lifting equipment, reducing the maintenance cost and prolonging the service life of the lifting equipment, thereby being a special electrical control box with high reliabilityand security monitoring function for the lifting equipment.

Description

technical field [0001] The invention belongs to the field of hoisting equipment, in particular to a special electrical control box for hoisting equipment with a safety monitoring function. Background technique [0002] Lifting equipment is widely used, and the safety of its use cannot be ignored, because the general task of lifting equipment is to carry or load and unload goods with large weight and volume. If an accident occurs, it will cause large economic losses. and casualties. Lifting equipment cannot work within the specified voltage and current range, or excessively frequent brakes, or work under severe overload conditions, which may shorten the service life of the lifting equipment, or cause serious accidents. Therefore, the factors that may cause lifting equipment accidents or affect the service life of lifting equipment are detected and controlled, for example, 1. Operating voltage; 2. Motor current when running up, down, left, right, forward and backward; 3. The...
