technical field

The invention relates to the field of a piston body of a piston type oxygen compressor, in particular to a disassembling device for a piston body of a piston type oxygen compressor.

Background technique

At present, most of the 4M12 piston oxygen compressor piston body removal tools used on site are disassembled by rotating the piston rod on the piston body with a pipe wrench or a long rod wrench without fixed support, which has the following shortcomings in use: Turning the piston rod on the piston body with the pliers will scratch its surface. When the piston moves, the oil scraper ring and the scratched surface of the piston rod are not tightly combined and easy to leak oil, causing oil to enter the cylinder and easily explode, which is likely to cause safety accidents; Dismantling the piston body with a four-claw long rod wrench without fixed support requires at least three people, which is not conducive to improving the efficiency of maintenance work during work, and is time-consuming and labor-intensive.

Invention content:

The present invention adopts following technical scheme to realize the object of the invention:

A piston body dismounting device for a piston type oxygen compressor, including a four-claw long rod wrench, characterized in that: one end of the four claw long rod wrench is installed on the piston body of a piston type oxygen compressor, and the other end is connected to the sleeve The four-claw long rod wrench cooperates with the sleeve rod to generate a rotating torque, and the four-claw long rod wrench passes through the support plate, and the support plate is fixed to the end surface of the cylinder of the piston oxygen compressor.

As a further limitation of the technical solution, the four-claw long rod wrench is connected to the sleeve rod through a joint.

As a further limitation to the technical solution, the joint is an outer circle inner square joint.

As a further limitation of the technical solution, the four-claw long rod wrench is connected to the piston body of the piston oxygen compressor through a set of protrusions.

As a further limitation to the technical solution, the protrusions include four cylindrical protrusions.

As a further limitation to the technical solution, the support plate is a rectangular steel plate with a circular hole processed in the center and slot-shaped holes processed at both ends.

As a further limitation to this technical solution, the piston body of the piston oxygen compressor includes a piston and a piston rod, the front end of the piston rod is connected to the crosshead and the back cap, and the front end of the crosshead is connected to the back cap to connect the crosshead.

As a further limitation to the technical solution, the front end of the crosshead is connected to the connecting rod of the crankshaft.

Compared with the prior art, the advantages and positive effects of the present invention are: the present invention can be quickly positioned by installing a four-claw long rod wrench in the center of the support plate, and only one person needs to forcefully act on the sleeve rod to make the piston oxygen compressor The rotation of the piston body makes it easy to quickly install and disassemble, which not only reduces labor intensity, but also improves maintenance work efficiency. When disassembling and installing equipment, there is no damage to equipment parts. The structure is simple, easy to operate, convenient to manufacture, and low in cost.
