Full-function trolley electrical control system and control method based on lifting trolley

Abstract

The invention discloses a full-function trolley electrical control system based on a lifting trolley. The full-function trolley electrical control system comprises a lifting tool body, and further comprises a pair of reel hoisting mechanisms symmetrically arranged above the two ends of the lifting tool body, four sets of three-in-one auxiliary anti-swing reel mechanisms arranged above the four corners of the lifting tool body and an electronic control mechanism used for controlling the reel hoisting mechanisms and the four sets of the three-in-one auxiliary anti-swing reel mechanisms, whereineach reel hoisting mechanism comprises a hoisting rope and a main reel; each three-in-one auxiliary anti-swing reel mechanism comprises an auxiliary rope, an auxiliary reel and an auxiliary three-in-one mechanism; and the electronic control mechanism comprises a rectification unit, a brake unit, a hoisting mechanism frequency converter, an auxiliary three-in-one mechanism frequency converter, a main PLC and a driver control unit. The invention further discloses a full-function trolley electrical control method based on a lifting trolley. According to the full-function trolley electrical control system based on the lifting trolley and the full-function trolley electrical control method based on the lifting trolley, the dual hoisting synchronized operation of a crane is realized, and the anti-swing performance index of a lifting tool of the crane is improved.

Description

technical field [0001] The present invention relates to a crane, and more specifically, relates to a full-function trolley electrical control system and its control method based on a trolley, which can be applied to a tire crane, a rail crane and various cranes equipped with a trolley for hoisting. . Background technique [0002] At present, the crane products of various manufacturers in the world have realized the functions of the spreader through their own unique technical means, including: the plane rotation of the spreader, the left and right tilt of the spreader, the forward and backward translation of the spreader, and the left and right translation of the spreader. part or all of the control. At the same time, efforts must be made to improve the anti-sway performance index of the spreader to facilitate the driver's operation. [0003] When the crane is in the handling operation, the large and small vehicles will generate acceleration and braking acceleration, which ...

AI Technical Summary

Problems solved by technology

[0003] When the crane is in the handling operation, the large and small vehicles will generate acceleration and braking acceleration, causing the goods under the suspension point to shake, and the driver cannot immediately pick up and unload the goods, thus prolonging the working cycle and reducing production efficiency

However, at present, in this regard, domestic manufacturers still have no method to fully realize the above-mentioned spreader operating functions, and at the same time, the anti-sway performance index of the spreader cannot be further improved.
