Lifting appliance for lifting reinforcement cage and hoisting machine

Abstract

The invention provides a lifting appliance for lifting a reinforcement cage and a hoisting machine. M rows and n columns of lifting chain groups are arranged at the bottom of a truss, then multi-point lifting of the reinforcement cage on the same plane can be realized, each lifting chain group comprises k bearing chains with the lengths sequentially increased, and then multi-point lifting of the reinforcement cage on the same vertical line can be realized. A plurality of bearing rods are horizontally inserted into the reinforcement cage in a layered mode, lifting hooks are directly connected with the bearing rods, and the bearing rods make contact with all framework pieces and steel bars of the layer where the bearing rods are located. According to the lifting appliance for lifting the reinforcement cage and the hoisting machine, the lifting tension borne by the reinforcement cage is uniformly distributed at a plurality of point positions of a three-dimensional space of the reinforcement cage, so that the lifting tension borne by each point position is effectively reduced, then the problem of fracture possibly caused by large tension borne by the framework pieces or the steel bars is avoided, deformation of the reinforcement cage is also prevented, and meanwhile, the reinforcement cage can be kept balanced during lifting through multi-point lifting.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hoist and hoisting machinery for hoisting a reinforcement cage. Background technique [0002] The urban comprehensive utility gallery has the advantages of ensuring the safety of municipal pipelines, improving the utilization rate of underground space, beautifying the urban environment, and avoiding repeated excavation of the road surface. It is the need for the development of new urbanization. With the popularization of the prefabricated assembly construction technology of pipe gallery in urban comprehensive pipe gallery, the construction of pipe gallery is gradually moving towards standardization, modularization and factoryization. [0003] In the large-scale production of the overall prefabrication of the pipe gallery, the steel cage needs to be hoisted as a whole and transported to the formwork for pouring. However, in the prior art, the hoisting equipment is on...

Problems solved by technology

[0004] The invention provides a sling and a lifting machine for hoisting a reinforcement cage, which is used to solve the problem in the prior art that the sling is only connected to the skeleton piece or reinforcement at the top of the reinforcement cage, which causes deformation or damage to the reinforcement cage during hoisting. Defects, to achieve at least simultaneous hoisting of the top and bottom of the steel cage, and at the same time distribute the hoisting force to each skeleton piece through the load-bearing rod
