Abstract

The invention relates to the technical field of hoisting equipment, and discloses large box girder hoisting equipment. The large box girder hoisting equipment comprises supporting legs, a supporting frame is fixedly connected to the bottom end of a steel rope, a driving rod is slidably connected to the bottom end of the supporting frame, supporting blocks are fixedly mounted at the positions, on the two sides of the driving rod, of the bottom end of the supporting frame, first sliding rods are fixedly mounted on the inner walls of the supporting blocks and the supporting frame, first moving blocks are slidably connected to the first sliding rods, driving rods are fixedly mounted at the bottom ends of the first moving blocks, second sliding rods are fixedly mounted in first grooves, supporting plates are slidably connected to the second sliding rods, first contacts are fixedly mounted on the supporting plates, second contacts corresponding to the first contacts are fixedly mounted at the bottom ends of the first grooves, and an alarm is fixedly mounted on the outer side wall of the supporting frame. By arranging an alarm mechanism, an operator is reminded, hoisting operation is stopped in time, and therefore, larger hoisting accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a large box girder hoisting equipment. Background technique [0002] Box girders are divided into prefabricated box girders and cast-in-place box girders. The prefabricated box girder combined with the bridge erecting machine can be erected after the completion of the substructure, which can speed up the progress of the project and save the construction period; the cast-in-place box girder is mostly used for large continuous bridges. Commonly divided by materials, there are two main types, one is prestressed reinforced concrete box girder, and the other is steel box girder. [0003] The box girder needs to be moved and installed with large-scale hoisting equipment during installation. The size and weight of the box girder are relatively large, which makes the hoisting equipment have greater safety hazards during hoisting, and the hoisting weight is prone to exceed the...
