Lifting equipment and engineering machinery vehicle closing method

Abstract

The invention relates to the field of engineering machinery production and manufacturing equipment, and discloses hoisting equipment and an engineering machinery vehicle closing method.The hoisting equipment comprises a winding plant, a hoisting device, a hoisting device, a hoisting device, a hoisting device, a hoisting device and a hoisting device, and the hoisting device can wind or release a sling (11); a hanger assembly (3) arranged to be able to be locked relative to a workpiece, the free end of said sling (11) being able to be connected to the hanger assembly or to the workpiece locked relative to the hanger assembly, and by winding or releasing the sling, the hanger assembly being rigidly fixed relative to the winding device or flexibly suspended by said sling, and therefore, shaking of the hanging bracket assembly and the workpiece can be selectively limited or allowed. According to the lifting equipment, shaking of the lifting frame assembly and the workpiece hung on the lifting frame assembly can be limited through rigid lifting in the lifting process, the workpiece can be quickly and safely lifted to the preset position, and the requirement for flexible adjustment can be met through flexible hanging in the hole assembling process; and the assembling efficiency and the operation safety in the vehicle closing process can be effectively improved.

Description

technical field [0001] The invention relates to construction machinery production and manufacturing equipment, in particular to a hoisting equipment. In addition, the present invention also relates to a method for combining vehicles of construction machinery using the hoisting equipment. Background technique [0002] In the manufacturing process of construction machinery such as excavators, cranes, etc., it is usually necessary to use flexible spreaders (slings) to hoist the upper frame, and lift it to the top of the lower frame by, for example, a crane, and manually operate the crane to lift, Translation, supplemented by manual adjustment, aligns the mounting holes of the upper frame and the lower frame, thereby completing the assembly operation of the upper frame and the lower frame. Similarly, before processing a large workpiece, the workpiece to be processed needs to be hoisted to a positioning position on the machine tool for precise processing, and manual adjustment i...

Problems solved by technology

[0005] The object of the present invention is to overcome the problem in the prior art that the workpiece being lifted is prone to shaking during the manufacturing process of construction machinery, and to provide a lifting device that can timely limit the lifting of the workpiece during the process of lifting the workpiece. The shaking of the frame assembly and the workpiece suspended on it is suitable for improving assembly efficiency and operation safety in the assembly of construction machinery and other assembly and workpiece processing.
