A bridge hoisting device

Abstract

The invention discloses bridge hoisting equipment which comprises a base plate. A winding reel is arranged at the top of the base plate, a strip-type protruding plate is arranged on the inner wall ofthe winding reel, a first rotating barrel and a second rotating barrel are arranged inside the winding reel, strip-shaped sliding grooves are formed in the exteriors of the first rotating barrel and the second rotating barrel, baffles are arranged at the ends of the first rotating barrel and the second rotating barrel, a first rotating shaft is arranged inside the first rotating barrel, and a bossis arranged at one end of the first rotating shaft. According to the bridge hoisting equipment, the first rotating barrel and the second rotating barrel are driven by a first lead screw to move leftand right, strip-shaped protruding plates and the strip-shaped sliding grooves are movably clamped and connected, mounting and demount of the winding reel are facilitated, and the winding reel can bedriven by the first rotating barrel and the second rotating barrel to rotate for winding; and rollers are arranged at the bottoms of the first lead screw, a second lead screw and the baffles, the demounting and mounting stability of the winding reel is improved, the stability of even winding of ropes driven by a wire clamping groove is improved, a second rotating shaft and a first rotating shaft are clamped and connected, the first rotating shaft is driven by the second rotating shaft to rotate, the structure is simple, and energy consumption and cost are reduced.

Description

technical field [0001] The invention relates to the field of bridge hoisting equipment, 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. The traditional man-made cable hoisting is time-consuming, labor-intensive, poor in stability and slow in speed; large cranes are bulky and unsuitable in many occasions with insufficient space; some automatic rope-retracting devices use the turntable to reel in the rope when retrieving 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. [0003] Therefore, it is necessary to invent a kind of bridge hoisting equipment to solve the above problems. Contents of the...
