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...
