Anti-twisting device for crane luffing steel wire rope

Abstract

The invention discloses an anti-kinking device for a luffing wire rope of a crane and the crane. The anti-kinking device comprises a base. The top end of the base is provided with a sliding rail. Thesliding rail is slidably connected with a sliding seat. One side of the surface of the sliding seat is connected with a first mounting seat through a first electric telescopic rod. The other side of the surface of the sliding seat is connected with a second mounting seat through the first electric telescopic rod. According to the anti-kinking device for the luffing wire rope of the crane and the crane, an infrared transmitter emits an infrared signal and then receives, the infrared transmitter sends received data to a PLC controller, after the PLC controller processes data information, and thedata information is contrasted and analyzed with initial collected information data; when the degree of approximation of initial information and contrast information is less than eighty percent, thePLC controller makes an alarming device work, thus a user is reminded, and the user can overhaul as soon as possible, thus the safety of operation is ensured.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to an anti-twisting device for luffing wire ropes of a crane. Background technique [0002] Today's large luffing jib tower cranes represent contemporary heavy-duty construction cranes with high lifting capacity, high lifting height and high lifting speed. The design of the boom of the large-scale boom tower crane adopts the "rod" structure, which has better stability than the "beam" structure of the flat-arm tower crane. The boom structure accounts for a smaller proportion of the whole machine structure, and the maximum lifting capacity is larger. When the luffing steel wire rope of the boom tower crane uses a new steel wire rope, due to the large self-torque in the steel wire rope, it is easy to twist after being put into use. , belonging to the technical field of construction machinery. The device part mainly includes a connecting arm. Both ends of the connecting arm...

AI Technical Summary

Problems solved by technology

The device part mainly includes a connecting arm. Both ends of the connecting arm are fixedly connected to a steel pipe, and the end of the steel pipe not connected to the connecting arm is fixedly connected to the upper steel plate. The upper steel plate is fixedly connected to the lower steel plate through fasteners. Although it can be twisted However, it is impossible to effectively prevent the occurrence of twisting. Most of the twisting occurs because the steel wire rope itself is relatively loose when retracting and unwinding the steel wire rope during use, which makes the retracted steel wire rope more messy and easily causes However, there is currently no device on the market that can prevent the wire rope from being twisted, which has caused great inconvenience to people's use.
