Scissor type lifting tool for plate stacking

Abstract

The invention relates to a scissor type lifting tool for plate stacking. The scissor type lifting tool comprises a scissor type lever mechanism, a main frame, a locking device and a lifting rod, wherein the scissor type lever mechanism comprises two bilaterally symmetrical connecting rod mechanisms, the main frame comprises a fork-shaped bottom plate, a machine body connected onto the fork-shaped bottom plate as well as machine body crosspieces and push-pull handles which are arranged on the machine body, the locking device comprises bottom locking rods, short locking connecting rods, locking rods, a steel unlocking cable and an unlocking pull ring which are connected onto the upper side of the machine body, and the lifting rod is arranged at the top of the machine body. Compared with the prior art, the scissor type lifting tool has the advantages that the lifting tool is safe and reliable, the working efficiency is improved, the quality of semi-finished products is guaranteed and the like.

Description

technical field [0001] The invention relates to a sling, in particular to a scissor sling used for plate stacking. Background technique [0002] At present, when lifting the stacks of plates (steel, plastic, plastic steel, glass, rubber, metal, wood, cardboard, fiber, etc.), the commonly used spreader is a sling; the stacks of plates need to be firmly bound before lifting , to prevent random stacking during the lifting process; during the lifting process of the sling, it is necessary to try the lifting many times to find the position of the center of gravity and a reasonable lifting point, and the lifting efficiency is low; in addition, the plate stacking is located between the two lifting points The part is concave due to the action of gravity, and it is easy to slip off the sling to cause a safety accident. Therefore, there is a limit to the thickness of the stack, and it cannot be lifted too much at one time; and for the semi-finished products that have been cut, it is ea...

[0002] At present, when lifting the stacks of plates (steel, plastic, plastic steel, glass, rubber, metal, wood, cardboard, fiber, etc.), the commonly used spreader is a sling; the stacks of plates need to be firmly bound before lifting , to prevent random stacking during the lifting process; during the lifting process of the sling, it is necessary to try the lifting many times to find the position of the center of gravity and a reasonable lifting point, and the lifting efficiency is low; in addition, the plate stacking is located between the two lifting points The part is concave due to the action of gravity, and it is easy to slip off the sling to cause a safety accident. Therefore, there is a limit to the thickness of the stack, and it cannot be lifted too much at one time; and for the semi-finished products that have been cut, it is easy to cause deformation and surface damage due to multiple clamping

[0003] Chinese patent CN203269320U discloses a scissor spreader, including a suspension ring, a first handle, a second handle, a first chain, a second chain and a self-locking device, the first chain and the second chain are connected to the suspension ring, the first The end of the handle is connected to the first chain, the end of the second handle is connected to the second chain, the middle part of the first handle and the second handle are hinged together to form a scissors structure, and the front ends of the first handle and the second handle are both There is a clamping part for clamping hole-type workpieces, and the self-locking device includes a lock hook installed on the second handle and a sawtooth on the first handle, so that by clamping the first handle and the front end of the second handle The part is inserted into the hole for lifting the workpiece to realize the lifting of the workpiece, but there are still some defects when lifting the stacked plates
