Abstract

The invention provides a self-tightening lifting appliance comprising a cross beam, four chains and an X-shaped snap gauge which is formed by crossing and overlapping two battens, wherein the crossing and overlapping part of the X-shaped snap gauge is movably connected by an articulated shaft; the cross beam is arranged above the X-shaped snap gauge; the two ends of each batten and one end of one of the four chains are fixed respectively, the other ends of the chains on the different battens are connected in pairs to form a first connection point and a second connection point, and the first connection point and the second connection point are respectively fixed on the two ends of the cross beam. The self-tightening lifting appliance is simple and reasonable in structure, solves various problems in the prior art, and is capable of lifting a scrapper safely, rapidly, easily, conveniently and effectively.

Description

technical field [0001] The invention relates to a lifting tool, in particular to a self-tightening spreader. Background technique [0002] With the popularization and use of fully-mechanized mining equipment, the disassembly and assembly business volume of fully-mechanized mining equipment is also increasing. At present, the installation and dismantling of scraper machines in underground coal mine construction generally use manual hoisting. see figure 1 , the commonly used scraper machine has the chute structure shown in the figure, and the cross-section of the scraper machine chute is usually a U-shaped trough with a reduced opening; the existing scraper machine hoisting method is: hang the anchor chain bolt in the scraper machine chute The appropriate position (such as the through hole on the side wall of the chute), and then lift. However, the existing manual operation is time-consuming, labor-intensive, and inefficient, and it is easy to cause safety hazards in hoistin...
