Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described:

[0019] Such as Figure 1-3 As shown, a fixed-distance millimeter-level precise positioning system for the hoisting mechanism of a tower crane includes components such as a programmable controller, a frequency converter, a touch screen, an encoder, a control handle, and a control switch. The programmable controller is respectively connected to the control system, frequency converter, comparative analysis encoder and control switch, the frequency converter is connected to the hoisting mechanism of the tower crane, the programmable controller collects the instructions set by the touch screen and the control handle, and comparative analysis of the encoder The transmitted moving distance signal controls the operation and stop of the frequency converter, and realizes the millimeter-level precise positioning operation of the tower crane hoisting mechanism. The control system inc...

Abstract

The invention relates to a millimeter level precisely positioning system for the distance ranging of the hoisting mechanism of a tower crane. The system is characterized by comprising a programmable controller, which is connected to a control system, a frequency converter, a contrastive analysis encoder, and a control switch. The frequency converter is connected to the hoisting mechanism of a tower crane. The control system comprises a multi-section millimeter level range-fixed moving mode. The programmable controller collets commands, which are set by the control system, controls the operation and stopping of the frequency converter based on moving distance signals from the contrastive analysis encoder, and realizes millimeter level precise positioned operation of the hoisting mechanism of the tower crane. The precision is high, the operation is simple, time and labor are saved, and the operation difficulty is reduced. The problems that the positioning is difficult because the movingdistance is short, and the workpiece is damaged are solved.

Description

technical field [0001] The invention relates to a millimeter-level precise positioning system for a tower crane hoisting mechanism. Background technique [0002] At present, when the tower crane is used to assemble the PC (prefabricated building) components, the tower crane often needs to move a small distance to realize the reinforcement hole. The operating speed of existing mechanisms generally exceeds 80m / min, and the operating speed of the first gear is 4.8m / min, which is 80mm / s per second. Existing methods are based on the experience and feeling of the driver to jog the tower crane to the first gear, but the moving distance of each operation is different, the reaction is faster and the movement is 20mm, the reaction is slower and the movement is 50mm, and it all depends on the driver. The staff is familiar with the tower crane and the operation proficiency. [0003] Due to the different operating habits and levels of each driver, it is necessary for the driver to adap...
