Special lifting appliance of large volume van vehicle carriage assembly

Abstract

The invention provides a special lifting appliance of a large volume van vehicle carriage assembly, which comprises a pear-shaped lifting ring, D-shaped shackles, flat lifting belts with two end buckles, pin shafts, cotter pins, lifting hook assemblies, a supporting plate, a rear plate, and a magnetic bar; the D-shaped shackles can be fixedly arranged at the outer end of the pear-shaped lifting ring through a buckle structure correspondingly, and the flat lifting belts with the two end buckles are fixedly fixed to the bottoms of the D-shaped shackles through lock catches; the pin shafts are fixedly arranged at the bottoms of the flat lifting belts with the two end buckles through lock catches, and the lifting hook assemblies are movably arranged at the outer ends of the pin shafts throughthe cotter pins matched with spacers; arrangement of the supporting plate and the rear plate provides convenience for the assembly, the supporting plate and the rear plate form a whole by welding, overall stiffness and load capacity are substantially provided, structural safety of the lifting appliance is improved, lifting hooks and the lifting ring are connected together through the lifting belts, a profile modeling lifting hook structure is fully used, it is convenient to hang and fix a carriage, operation is simple, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of car box lifting, and more specifically relates to a special spreader for a large-capacity van car box assembly. Background technique [0002] The spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used spreaders for lifting the finished items are hooks and slings. Others include lifting rings, lifting suction cups, clamps and forks. When it is used through the cooperation of multiple sets of parts, the box of the van is assembled in the workshop, and after assembly, the spreader is set on the crane equipment to carry the box. [0003] Based on the above, the generally used hoisting tools use wire rope hoisting. During the hoisting process, it is easy to cause surface bumps and scratches to affect the service life of the workpiece, and the work efficiency is low, it is inconvenient to disassemble and use, and it is not conducive to production. There is no ...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a special spreader for the large-volume van box assembly, to solve the problem that the generally used spreader proposed in the above background technology adopts a wire rope hoist, and it is easy to cause bumps and scratches on the surface during the hoisting process. It affects the service life of the workpiece, and the work efficiency is low, it is inconvenient to disassemble and assemble, it is inconvenient to use, and it is not conducive to production. Moreover, there is no anti-skid structure in the wire rope crane, and it may fall off, which has certain safety hazards.
