Description

Semi-automatic lifting appliance equipment for narrow space Technical Field The utility model relates to lifting appliance equipment, in particular to semi-automatic lifting appliance equipment for a narrow space. Background At present, when a pipeline is hoisted in a narrow space, a magnetic force crane can only be generally adopted, and due to structural limitation, once the hooking angle or the lamination is problematic, the condition that the pipeline falls easily occurs in the running process, the pipeline falls easily, so that a certain safety risk is caused for an operator, other personnel and equipment on a pipeline hoisting route are also in a high-risk area, serious safety accidents can occur, the hoisting operation of the pipeline is influenced, and the magnetic force crane is inconvenient, so that a semi-automatic hoisting device for the narrow space is needed. Disclosure of utility model Aiming at the defects and defects in the prior art, the utility model provides the semi-automatic lifting appliance equipment for the narrow space, which not only increases the lifting safety and reduces the working risk of lifting in the narrow space and the manufacturing cost and the later maintenance cost, but also can be widely applied to the lifting operation in the narrow space, but also can be widely applied to the lifting operation in the areas without power supply outside a factory building and the field, compared with other lifting appliances used for lifting pipelines, has the operation of not manually pulling lifting hooks on two sides, can reduce the labor intensity of workers, save the cost and improve the lifting efficiency. The semi-automatic lifting appliance equipment for the narrow space comprises a cross beam, lifting lugs are welded in the middle of the upper end of the cross beam, pull rope pulley blocks are arranged on two sides of the upper end of the cross beam, longitudinal beams are welded on two sides of the lower end of the cross beam, hook blocks are rotated in shaft holes below the two longitudinal beams, balancing weights are arranged on two ends of the cross beam, pull ropes are arranged between the balancing weights and the hook blocks, and the pull ropes are connected to the pull rope pulley blocks in a sliding mode. Further, a vertical limiting block is welded above the outer side of the longitudinal beam, and a horizontal limiting block is welded below the inner side of the longitudinal beam. Further, a bayonet lock is arranged on the balancing weight, and one end of the bayonet lock is abutted against the cross beam. Further, the four end corners of the hook block are rounded corners. Further, a shaft column mounting hole for mounting a shaft column, a stay rope mounting hole for connecting a stay rope and a bayonet lock through hole for plugging a bayonet lock are formed in the balancing weight, the shaft column mounting hole is formed in the top end of one side of the balancing weight, and the stay rope mounting hole is located above the shaft column mounting hole.
