In rod cavity；Piston rod one end is connect with piston, and thimble is arranged in the piston rod other end；Hydraulic cylinder, which is connected through a screw thread, to be arranged hydraulic
In cylinder sleeve, hydraulic cylinder is connect with limiting platform by jackscrew jaw song neck, and limiting platform is equipped with screw hole；Screw hole and top
Needle is located on same center line, and internal diameter and the thimble outer diameter of screw hole match.
Fuel feeding valve is additionally provided on the hydraulic cylinder, the lower section of hydraulic oiling handle, fuel feeding valve and hydraulic note is arranged in fuel feeding valve
Oily handle matches.
The hydraulic cylinder is tubulose, and thimble is stretched out from hydraulic cylinder.
The thimble is cylindric thimble or sleeve shaped thimble.
The bolt outer diameter of parallel groove clamp and the internal diameter of screw hole match.
The hydraulic cylinder and parallel groove clamp etc. are common equipment known in this field, there is sale on the market.
In use, hydraulic clamp handle is held, parallel groove clamp is placed on limiting platform, makes thimble alignment and ditch line
The bolt corroded on folder repeatedly extrudes fuel feeding valve by the hydraulic oiling handle on hydraulic cylinder and carries out oiling pressurization, makes in-oil cylinder
Piston moves forward, and thimble ejects bolt, and the parallel groove clamp on conducting wire is removed；After the completion of work, hydraulic oiling handle is unclamped,
Hydraulic in-cylinder pressure reduces, and piston returns to origin-location by return spring.
The beneficial effects of the utility model are: serious spiral shell will quickly can be corroded on parallel groove clamp in high altitude operation
Bolt ejection, is a kind of micro hydraulic tool, easy to carry, and hammering can not vacantly be applied by solving conducting wire, and chisel shovel is removed and ditch line
The difficulty of folder, significantly improves efficiency, reduces labor intensity, and eliminates safe hidden trouble.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model section schematic diagram；
In figure: hydraulic clamp handle 1, hydraulic oiling handle 2, hydraulic cylinder 3, hydraulic cylinder 4, screw hole 5, thimble 6, jackscrew jaw are bent
Neck 7, fuel feeding valve 8, hydraulic fluid chamber 9, piston 10, return spring 11, bolt 12, parallel groove clamp 13, conducting wire 14, limiting platform 15,
Piston rod 16.
Specific embodiment
Below in conjunction with attached drawing, the utility model is further described by embodiment.
It is a kind of for dismantle parallel groove clamp bolt hydraulic jackscrew clamp, include hydraulic gun, hydraulic jackscrew jaw and thimble 6,
The hydraulic gun includes hydraulic clamp handle 1, hydraulic oiling handle 2 and hydraulic cylinder 3, and hydraulic jackscrew jaw includes hydraulic cylinder 4, screw hole
5, jackscrew jaw song neck 7 and limiting platform 15, the hydraulic clamp handle 1 and hydraulic cylinder 3 connect, and hydraulic oiling is arranged on hydraulic cylinder 3
Handle 2, hydraulic cylinder 3 is interior to be equipped with piston 10, and piston 10 will be divided into hydraulic fluid chamber 9 and rod end chamber, cover on piston rod 16 in hydraulic cylinder 3
Return spring 11 is filled, is collectively disposed in rod end chamber；16 one end of piston rod is connect with piston 10,16 other end of piston rod setting top
Needle 6；Hydraulic cylinder 3, which is connected through a screw thread, to be arranged in hydraulic cylinder 4, and hydraulic cylinder 4 and limiting platform 15 are bent by jackscrew jaw
