Unmanned grab bucket travelling crane steel wire rope deviation rectifying device

Abstract

The invention discloses an unmanned grab bucket travelling crane steel wire rope deviation rectifying device. The unmanned grab bucket travelling crane steel wire rope deviation rectifying device comprises a detection device, an intermediate relay, a digital input device, a CPU device, a communication device and a frequency converter. The detection device is connected with a steel wire rope rollerand used for generating a signal when making contact with a steel wire rope. The intermediate relay is connected with the detection device and used for collecting the signal of the detection device.The digital input device is connected with the intermediate relay and used for receiving a signal of the intermediate relay. The CPU device is connected with the digital value input device and used for receiving the signal and transmitting a command. The communication device is connected with the CPU device and used for receiving and outputting the command. The frequency converter receives the command transmitted by the communication device and controls a crane to move. Through the unmanned grab bucket travelling crane steel wire rope deviation rectifying device, the technical problems that asteel wire rope is inclined to come out from a roller and be wound and the working efficiency is reduced due to the fact that a grab bucket of an unmanned grab bucket travelling crane is often inclined left and right are solved.

Description

technical field [0001] The invention relates to the technical field of unmanned grab driving, in particular to a wire rope deviation correcting device for unmanned grab driving. Background technique [0002] As a new product in the field of informationization and intelligence, unmanned grab driving has been widely used in metallurgical enterprises, but usually the material level is uncertain, and the detection method is to indirectly judge the material pool through the weighing system of the grab The amount of material, this method is too extensive, it is impossible to judge the shape and slope of the material surface, and when the grab bucket is placed on the material surface, the grab bucket often tilts left and right, causing the steel wire rope to tilt out of the groove from the drum, and it is easy to cause the grab bucket to rotate several times and the wire rope to be entangled Fracture will seriously affect the safety of equipment, increase maintenance workload and r...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a steel wire rope deflection correction device for unmanned grab driving, which solves the technical problem that the grab bucket tilts left and right, which often occurs in unmanned grab driving in the prior art, causing the steel wire rope to wind from the drum out of the groove and reduce work efficiency.
