Beam body hoisting device convenient to operate

Abstract

The beam body hoisting device convenient to operate comprises a steel wire rope, an upper beam body and a steel box beam, a damping mechanism is installed on the upper beam body and used for damping when the steel wire rope violently shakes in the hoisting process, a lower beam body is installed at the lower end of the upper beam body, and the upper beam body and the lower beam body are arranged in parallel; and the plane rotation angle and the vertical plane rotation angle of the lower beam body can be adjusted relative to the upper beam body. The damping mechanism is arranged for damping when the steel wire rope violently shakes in the hoisting process, the plane rotation angle and the vertical plane rotation angle of the lower beam body can be adjusted relative to the upper beam body, the adjusting driving mechanism is arranged on the upper beam body, and the adjusting driving mechanism can choose to adjust the damping mechanism or adjust the plane rotation angle of the lower beam body. In this way, large potential safety hazards in a complex environment are avoided. The horizontal position and the inclination angle of the steel box girder do not need to be adjusted by pulling of people, accurate positioning of the steel box girder is guaranteed, and high quality of bridge erection is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to a beam body hoisting device with convenient operation. Background technique [0002] With the rapid economic development of the times, the requirements for the convenience of road traffic are getting higher and higher. The construction of bridges is undoubtedly one of the most important undertakings to improve the convenience of road traffic. The construction of bridges is usually carried out through multiple prefabricated The steel box girders are spliced ​​together. During the construction process, the prefabricated steel box girders need to be hoisted to the construction point by hoisting equipment. During the hoisting operation, the precise positioning of the steel box girders is directly related to the quality of the bridge erection. The box girder and the hoist are directly connected by steel wire ropes. The flexibility of the steel wire rope causes the steel box g...

Problems solved by technology

[0002] With the rapid development of the economy of the times, the requirements for the convenience of road traffic are also getting higher and higher. The construction of bridges is undoubtedly one of the most important undertakings to improve the convenience of road traffic. The construction of bridges is usually done through multiple prefabricated The steel box girder is spliced ​​together. During the construction process, the prefabricated steel box girder needs to be hoisted to the construction point by hoisting equipment. During the hoisting operation, the precise positioning of the steel box girder is directly related to the quality of the bridge erection. The existing hoisting equipment will The box girder is directly connected to the hoist through a wire rope. The flexibility of the wire rope causes the steel box girder to shake seriously during hoisting, especially in complex environments such as the sea, which poses a greater safety hazard; other existing hoisting equipment only It is possible to hoist the steel box girder to a location close to the construction, and then adjust the horizontal position and inclination angle of the steel box girder by pulling it manually. The precise positioning of the steel box girder cannot be guaranteed, which will lead to a decrease in the quality of the bridge erection. In view of this, we propose a Easy-to-operate beam body lifting device
