Control system and control method of tower crane lifting hook and tower crane

Abstract

The disclosure relates to a control system and control method of a tower crane lifting hook and a tower crane. The control system of the tower crane lifting hook comprises an amplitude-changing trolley and the lifting hook, wherein the amplitude-changing trolley is arranged on a cargo boom of the tower crane, and the lifting hook is connected with the amplitude-changing trolley through steel wire ropes. A first position sensor used for collecting a first position of the amplitude-changing trolley is arranged on the amplitude-changing trolley, and a power unit used for moving the lifting hook, a second position sensor used for collecting a second position of the lifting hook and a controller are arranged on the lifting hook; and the controller is connected with the first position sensor and the second position sensor, and the controller controls the power unit to move the lifting hook from the second position to the first position.

Description

technical field [0001] The present disclosure relates to the field of construction, in particular to a tower crane hook control system, a control method thereof, and a tower crane. Background technique [0002] Cranes are important lifting equipment in the construction industry, and tower cranes are one of the essential lifting equipment. Tower cranes, also known as "tower cranes", are used to lift construction materials such as cement soil, steel bars, corrugated wood, and steel pipes. like figure 1 As shown, the tower crane mainly includes a tower crane base 101 fixed on the ground, a control room 102, a boom 103, a luffing trolley 104 arranged on the boom 103, and a crane connected to the luffing trolley 104 through a wire rope 105. Hook 106. During the construction process of the tower crane, by controlling the movement of the luffing trolley along the boom and adjusting the position of the hook, it is possible to realize lifting or lowering at different positions and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this disclosure is to provide a tower crane hook control system and its control method and tower crane, which can solve the problem of the hook swinging back and forth because the luffing trolley and the tower crane hook are not on the same vertical line, and at the same time improve the efficiency of the tower crane during operation. Accuracy and rapidity of lifting and lowering operations
