Lifting equipment system and control method thereof

Abstract

The invention discloses a lifting equipment system and a control method thereof. The control method adopts a radar distance measuring mode to detect a motion distance of lifting equipment, corrects the motion distance, and controls the motion of the lifting equipment according to the corrected distance and a preset threshold. The lifting equipment system comprises a distance measuring sensor, a controller, an execution mechanism and input mechanism; the distance measuring sensor is used for measuring the motion of the lifting equipment; the controller calculates the motion distance for correction according to measured data, and outputs control signals; the execution mechanism is acted according to the control signals; and the input equipment is used for inputting parameters. The motion distance of the lifting equipment can be precisely measured to prevent mechanical collision, so that the damage of the lifting equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hoisting equipment system and a control method thereof. Background technique [0002] Lifting equipment is an extremely important equipment in the crane industry, and its performance is related to the safety of personnel and equipment. In actual use, the equipment needs reliable action at two positions, namely the pre-limit position and the limit position. The pre-limit position is to slow down the motor and switch from high speed to first gear; the limit position is to stop the motor. If the motor is stopped directly from the high-speed gear, the stopping distance is long due to the large inertia of the lifting equipment, and the brake pads wear quickly, so it is necessary to decelerate the motor to the first gear from the preset position (the first gear speed is generally 5 to 10 times the full speed. %), and then brake, so that the braking distance is short, and ...

AI Technical Summary

Problems solved by technology

[0004] Due to the harsh working environment of the lifting equipment and the huge dust, the life of the travel switch is short; the photoelectric switch is easily affected by the dust, and it is prone to misoperation, so the lifting equipment collides

[0005] In the prior art, in order to prevent collisions, buffers are installed on both sides of the lifting equipment. When a collision occurs, the buffers absorb energy. However, this mechanical protection method has poor protection effect and easily causes damage to the lifting equipment.
