Abstract
A single hydraulic prop three-purpose valve disassembling device comprises a sleeve, a fixed pipe fitting, an iron chain and a special penetrating pin. One end of the sleeve is sleeved into the rotating shaft end, and the other end of the sleeve is welded with the fixed pipe fitting. The fixed pipe fitting is a steel pipe with the diameter of 25mm, one end of the fixed pipe fitting is welded with the sleeve, and a hole penetrating through the fixed pipe fitting is drilled at the position 20mm away from the end part of the fixed pipe fitting at the other end of the fixed pipe fitting. One end of the iron chain is fixed on the sleeve, and the other end of the iron chain is connected with the special penetrating pin. The special through pin is an iron rod which is used for penetrating through the fixed pipe fitting and being fastened. The utility model has simple manufacturing process, firm manufacturing, higher strength, smaller volume and convenient carrying; the disassembly speed can be improved, and the working efficiency is improved; greatly saving manpower, material resources and financial resources.
Description
Technical Field
The utility model relates to a mining equipment field especially relates to a special ware of tearing open of hydraulic prop three way valve.
Background
The single hydraulic prop is largely used in advance support or gob-side entry retaining of a coal face, but the advance support for a long time always generates single-prop dead columns, liquid discharge and the like, so that personnel are required to replace three valves of the single prop during maintenance, and the traditional replacement mode adopts a long-rod drill rod to penetrate into three valve holes for manual disassembly.
Disclosure of Invention
The utility model discloses a main aim at provides a ware is torn open to hydraulic prop three way valve can effectively solve the problem among the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a single hydraulic prop three-purpose valve disassembling device comprises a sleeve, a fixed pipe fitting, an iron chain and a special penetrating pin.
One end of the sleeve is sleeved into the rotating shaft end, and the other end of the sleeve is welded with the fixed pipe fitting.
The fixed pipe fitting is a steel pipe with the diameter of 25mm, one end of the fixed pipe fitting is welded with the sleeve, and a hole penetrating through the fixed pipe fitting is drilled at the position 20mm away from the end part of the fixed pipe fitting at the other end of the fixed pipe fitting.
One end of the iron chain is fixed on the sleeve, and the other end of the iron chain is connected with the special penetrating pin.
The special through pin is an iron rod which is used for penetrating through the fixed pipe fitting and being fastened.
Compared with the prior art, the utility model has simple manufacturing process, firm manufacturing, higher strength, less damage after long-term use, smaller volume and convenient carrying; when in use, the manual disassembly is not needed, and the unnecessary labor consumption can be solved; the disassembly speed can be improved, and the working efficiency is improved; mechanical kinetic energy (pneumatic) is utilized for disassembly, and manual operation is not needed; greatly saving manpower, material resources and financial resources.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
An embodiment of the invention is further described below with reference to the accompanying drawings:
a single hydraulic prop three-purpose valve disassembling device comprises a sleeve 1, a fixed pipe fitting 2, an iron chain 3 and a special penetrating pin 4.
One end of the sleeve 1 is sleeved into the rotating shaft end, and the other end of the sleeve is welded with the fixed pipe fitting 2.
The fixed pipe fitting 2 is a steel pipe with the diameter of 25mm, one end of the fixed pipe fitting is welded with the sleeve 1, and a hole penetrating through the fixed pipe fitting is drilled at the position 20mm away from the end part of the fixed pipe fitting at the other end of the fixed pipe fitting.
One end of the iron chain 3 is fixed on the sleeve 1, and the other end is connected with the special penetrating pin 4.
The special through pin 4 is an iron rod which is used for penetrating through the fixed pipe fitting 2 and being fastened.
Use the utility model discloses during the device, only need embolia the pivot end with 1 one end of sleeve, will wear round pin 4 to alternate with sleeve welded diameter 25 mm's fixed pipe fitting 2 through the special use that iron chain 3 links to each other with sleeve 1, then wear round pin 4 both ends fastening can utilize the rotatory moment of torsion of pnematic spanner with the special use three valves of monomer post of pegging graft, not only convenient but also swift, the labour's of unnecessary when having solved the manual work and disassembling consumption.
