Lifting appliance with levelling function

Abstract

The invention discloses a lifting appliance with a levelling function. The lifting appliance comprises a lifting appliance body, wherein a square inserting groove is formed in the bottom of the lifting appliance body, a positioning groove is formed in the rear side of the inner wall of the square inserting groove, a fixing mechanism is arranged inside the front side of the lifting appliance body, and a square inserting block is inserted into the square inserting groove. According to the lifting appliance, the lifting appliance body, the square inserting groove, the positioning groove, the fixing mechanism, a threaded rod, a rotating handle, an extrusion block, the square inserting block, an automatic levelling instrument, an auxiliary positioning mechanism, an annular block, positioning columns, a circular groove, a cooperating groove, a storage groove, a positioning mechanism, a pushing rod, a pushing handle, a positioning rod, a positioning block, an extrusion spring, a signal receiver, a positioning hole, a circular cooperating hole, a square through hole, a limiting groove and a limiting block are arranged and used cooperatively, and therefore the problem that the existing levelling effect is poor is solved, and the lifting appliance with the levelling function has the advantage of good levelling effect.

Description

technical field [0001] The invention belongs to the technical field of slings, in particular to a sling with a leveling function. Background technique [0002] Spreader refers to the device for lifting heavy objects in hoisting machinery. The most commonly used spreaders for lifting items are hooks and slings. Others include lifting rings, lifting suction cups, clamps and forks, etc., which are widely used Used in the lifting industry. [0003] In order to meet the market demand, the spreader is generally optimized in terms of how to lift better and how to make it more convenient for users to use, often ignoring whether it can be well leveled, the spreader has a better lifting effect and It is more convenient for users to use these benefits, but there are certain limitations. In normal use, the internal leveling effect is often poor, and it is easy to cause a lot of shaking during the lifting process. The existing technology exists The problem is: the leveling effect is po...
