Tower holding device for wind power overhaul crane

Abstract

The invention discloses a tower holding device for a wind power overhaul crane. The tower holding device comprises a main arm, wherein a left secondary arm is arranged at the left end of the main arm;a rotating shaft I is arranged between the main arm and the left secondary arm; a rotating shaft II is arranged at the left end of the left secondary arm; a groove I is formed in the right side of the rotating shaft II; a limiting belt is arranged on the rotating shaft II; a left limiting block is arranged at the left end of the limiting belt; a motor is arranged at the front end of the rotatingshaft II; a left fixing block is arranged at the left end of the left limiting block; a T-shaped groove is formed in the upper end of the left fixing block; a fixing shaft is arranged on the left sideof the T-shaped groove; a limiting plate is arranged on the fixing shaft; and a bolt is arranged at the right end of the limiting plate. The tower holding device disclosed by the invention is small in occupied space and convenient to transport and store; the tower holding device is stable in connection, the safety of the tower holding device is improved, and the tower holding device can be tightly mounted on the surfaces of tower columns of different sizes and is prevented from sliding off during operation.

Description

technical field [0001] The invention belongs to the field of cranes, in particular to a tower holding device used for wind power maintenance cranes. Background technique [0002] Cranes refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range, also known as cranes, aerial cranes, and cranes; some work characteristics of lifting equipment are intermittent movements, that is, in a working cycle The corresponding mechanisms for the actions of retrieving, transporting and unloading work alternately, and the development and use of cranes in the market are becoming more and more extensive; due to the lack of outriggers for hoisting and hoisting, accidents often occur, and the driving speed is also relatively fast. The crawler crane is fast; the operation is stable, the lifting capacity is large, and it can lift and walk within a specific range, but it must ensure that the road is flat and solid, the tire pressu...

AI Technical Summary

Problems solved by technology

[0006] 2) By setting the T-shaped block and the T-shaped groove, the T-shaped block is rotated to the inside of the T-shaped groove, and then fixed on the upper end of the left fixed block by bolts, which can prevent the T-shaped block from falling from the T-shaped groove. It falls in the groove, which solves the technical problem that the connection of the existing tower holding device is not stable enough;

[0007] 3) The restricting belt with one end connected to the second rotating shaft is wound on the second surface of the rotating shaft through the motor, and the left restricting block and the left secondary arm will be close to each other, so that the tower holding device can be installed more closely on the surface of the tower column, which solves the problem of existing The technical problem of not being able to clamp tower columns of different sizes well
