Bridge hoisting machine

Abstract

The invention discloses a bridge hoisting machine. The bridge hoisting machine includes a rope receiving base body composed of a first base body and a second base body. An inner cavity extending leftand right is formed in the first base body, a first sliding-connecting groove is formed in the right side of the inner cavity, and a sliding-connecting block is arranged in the first sliding-connecting groove in a sliding fit connection mode. A pin shaft sleeve is arranged at the position, located in the inner cavity, on the left side surface of the sliding-connecting block, a pushing-connecting rod extending to the left side is arranged in the pin shaft sleeve in a rotating connection mode, and a pin shaft sleeve is arranged at the tail end of the left side of the pushing-connecting rod. A curved pin shaft is arranged in the pin shaft sleeve, the front side of the curved pin shaft is rotatably connected with the inner wall of the front side of the inner cavity, the rear side of the curvedpin shaft is connected with a rope receiving electricity transferring machine, and the rope receiving transferring machine is arranged in the inner wall of the rear side of the inner cavity and is fixedly connected with the inner cavity. A second sliding-connecting groove extending front and back is formed in the left side surface of the second base body, and a second sliding-connecting block isarranged in the second sliding-connecting groove. The bridge hoisting machine is simple in structure, fast installation and disassembly can be achieved, the replacement speed of a rope winding drum isimproved, and even rope receiving work is achieved.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge hoisting machine. Background technique [0002] In the process of bridge construction, it is often necessary to hoist materials such as silt concrete, steel pipe fittings, etc. from a low place to the bridge through hoisting equipment. Traditional man-made cable hoisting is time-consuming, labor-intensive, poor in stability, and slow in speed; large-scale cranes are bulky and unsuitable in many occasions where space is insufficient; some automatic rope-retracting equipment uses a turntable to retract the rope when retracting the rope, but these devices often There will be uneven distribution of the suspension rope on the rope reel, which greatly affects the stability of the rope collection, and it is very troublesome to replace the rope shaft. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bridge hoisting machine, ...
