Problems solved by technology

As a tool for hanging heavy objects, the sling is conducive to the lifting and lowering of the heavy objects and increases the transportation speed. However, it brings some problems: acceleration, deceleration and external interference will cause the heavy objects to swing, which may cause problems during transportation. Heavy objects collide with other equipment, causing unnecessary losses
[0004] There are still many imperfections in the traditional crane control system: it is difficult to run multiple transportation directions at the same time, which greatly increases the transportation time; Swing

Embodiment Construction

[0014] In the actual working environment, the target position of the heavy object cannot be accurately obtained. After reaching the set target position, manual fine-tuning is required to reach the actual target position. In addition, in order to prevent dangerous situations, the participation of the operator is required in the control process, which is called It is a semi-automatic control system. While the operator participates, the controller automatically detects the position, height and swing angle of the weight through the configured position sensor and angle sensor to generate a control signal.

[0015] 1. One-dimensional manual control

[0016] Similar to the traditional crane control, use "forward" to make the crane transport forward, but the difference is that after pressing this button, the control algorithm in the controller will make the crane perform anti-swing control while starting, when the crane motor reaches Stop the heavy object from swinging at the rated t...

Abstract

A semi-automatic control system for crane is composed of control panel, driver, crane system, controller for controlling the movement of crane and eliminating the swinging of weight, the weight height sensor for measuring the height of weight and its lifting speed, position sensor for measuring the position and speed of crane, and angle measuring unit for measuring 2D swinging angle and angle speed.

Description

technical field [0001] The invention relates to a semi-automatic control system of a crane, especially an automatic control system including an all-round heavy object transportation. Background technique [0002] As a heavy transport tool, cranes have been widely used in workshops, docks, warehouses, construction sites and other places. As a tool for hanging heavy objects, the sling is conducive to the lifting and lowering of the heavy objects and increases the transportation speed. However, it brings some problems: acceleration, deceleration and external interference will cause the heavy objects to swing, which may cause problems during transportation. Heavy objects collide with other equipment, causing unnecessary losses. This requires the operator to have quite skilled work experience to reduce the swing of the heavy object during transportation, and at the same time, there must be a worker at the target position to artificially eliminate the swing and place the heavy ob...
