Problems solved by technology

[0004] Although the structure of the above-mentioned screw jack is simple and easy to operate, the load-bearing ejector rod has a limited bearing capacity because it is thinner and longer. At the same time, the screw jack takes up a large space in the vertical direction. For those with small maintenance space in the vertical direction Very inconvenient to use for heavy equipment

Abstract

The invention discloses a wedge block type jack. The wedge block type jack comprises a bottom block, a top block arranged above the bottom block, a connecting device connecting the top block with thebottom block and a wedge block located between the top block and bottom block, wherein the top block can do reciprocating motion relative to the bottom block in the vertical direction, the wedge blockis provided with a wedge-shaped face coordinating with the top block, and the wedge block can drive the top block to do reciprocating motion in the vertical direction. The wedge block type jack is simple in structure and relatively large in bearing force, especially, less space is occupied in the vertical direction, and maintaining or replacing of parts with relatively small intervals in the vertical direction is facilitated.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a wedge type jack. Background technique [0002] For the daily maintenance and adjustment of equipment, especially for equipment with relatively small maintenance space, the commonly used tool is the jack. The overall disassembly of the equipment is very convenient to operate. [0003] Common jacks include mechanical jacks, hydraulic jacks, electric jacks, etc. Among them, mechanical jacks are less expensive to use, more convenient to carry, and more flexible to operate. The screw jack is the most common mechanical jack. The screw jack usually includes a base and a push rod. There are threaded holes on the base, and a threaded push rod is installed on the upper part. By twisting the push rod to raise it, the upper part is pushed to facilitate the maintenance or replacement of the lower parts. After the maintenance or replacement is completed, the mandrel is rotated to make it...
