Bridge hoisting equipment

Abstract

The invention discloses bridge hoisting equipment. The bridge hoisting equipment comprises a rope take-up base body composed of a first base body and a second base body. An inner cavity arranged in a left-and-right extending manner is formed in the first base body. A first slip groove is formed in the right side of the inner cavity. A slip block connected in a slip fit manner is arranged in the first slip groove. A pin shaft sleeve is arranged on the left side face of the slip block in the inner cavity. A pushing rod arranged in a leftward extending manner is rotationally connected in the pin shaft sleeve. A pin shaft sleeve is arranged at the tail of the left side of the pushing rod and is internally provided with a curved pin shaft. The front side of the curved pin shaft is rotationally connected with the inner wall of the front side of the inner cavity. The rear side of the curved pin shaft is connected with a rope take-up electric rotating machine in a matched manner. The rope take-up electric rotating machine is arranged in the inner wall of the rear side of the inner cavity and is fixedly connected. A second slip groove arranged in a front-and-back extending manner is formed in the left side face of the second base body. A second slip block is arranged in the second slip groove. The bridge hoisting equipment is simple in structure, fast mounting and demounting can be achieved, the replacement speed of a rope winding drum can be increased, and uniform rope take-up work can be achieved.

Description

technical field [0001] The invention relates to the field of bridges, in particular to bridge hoisting equipment. 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 device, w...
