Problems solved by technology

[0002] The hoisting height of a crane, such as a tower crane, increases with the height of the building, so only the front part of the wire rope is moving during the lifting operation for a long time, and the remaining wire rope wound on the crane drum is The building will only be used when it reaches a certain height. Therefore, when the tower crane is working at a low lifting height, only the front part of the s

Embodiment approach

[0039] see image 3 , according to the second embodiment of the present invention, the first reel body 3 can be power-connected with the drive shaft 2, the second reel body 4 is sleeved on the drive shaft 2, and the first reel body 3 and the second reel body Mounting holes for insertion of the insert 6 are respectively formed on the body 4, so that the first roll body 3 and the second roll body 4 can be connected when the insert piece 6 is inserted into the respective mounting holes of the first roll body 3 and the second roll body 4. The second reel body 4 is power connected. The insert 6 can be, for example, a pin shaft. In addition, the mounting holes can be formed at the ends of the first roll body 3 and the second roll body 4 facing each other, and along the first roll body 3 and the second roll body. A plurality of installation holes are distributed in the circumferential direction of 4, so that a plurality of inserts 6 can be adaptively used to improve the connection s...

Abstract

The invention discloses a reel device and a hoisting mechanism of a crane. The reel device comprises a work rope (1) and at least two reel bodies, wherein the work rope (1) is wound on the at least two reel bodies, so that the number of layers of the work rope (1) wound on each of the at least two reel bodies can be reduced. According to the reel device, the possibility of avoiding the occurrence of a rope clutterphenomenon is provided.

Description

technical field [0001] The invention relates to a reel device, in particular to a reel device and a lifting mechanism of a crane. Background technique [0002] The hoisting height of cranes, such as tower cranes, increases with the height of the building, so only the front part of the wire rope is moving during the lifting operation for a long time, and the remaining wire rope wound on the crane drum is The building will only be used when it reaches a certain height. Therefore, when the tower crane is working at a low lifting height, only the front part of the steel wire rope reciprocates on the drum, and the steel wire rope moving on the outer layer will temporarily move the inner layer. The non-moving steel wire rope produces extrusion force, and due to the large number of layers, it is easy to cause the phenomenon of disordered rope (that is, the phenomenon of uneven arrangement of the steel wire rope). The large impact seriously affects the performance of the tower cran...
