Abstract
The invention provides a hydraulic valve pulling device which is capable of saving labor, efficient and capable of improving the work efficiency. The hydraulic valve pulling device is provided with a trapezoidal screw rod. The lower end of the trapezoidal screw rod is connected with a hanging body through a back nut. The hanging body is connected with a hook body through a pin. An oil cylinder base and an oil cylinder are arranged in the middle of the trapezoidal screw rod. A nut is screwed on the oil cylinder and on the upper portion of the trapezoidal screw rod in a sleeved mode. A plane thrust bearing is arranged in the nut. A handle is fixed to the outer side of the nut. The hydraulic valve pulling device has the advantages that trapezoidal threads are adopted, so that torque is increased, the plane thrust bearing is additionally arranged in the middle of the nut, force is exerted easily, and rotation is flexible.
Description
Technical field
The invention belongs to instrument manufacturing technology field, particularly a kind of valve and dismantle hydraulic draw valve device used.
Background technology
Valve is because for a long time in corrosive environment, the often bad dismounting of corrosion, and hydraulic draw valve device is the most frequently used instrument.The current valve device jacking system that pulls out adopts regular screw threads, and moment of torsion is less, and the valve serious for corrosion cannot unplug, and adopts plain nut rotation underaction, Comparision effort simultaneously.
Summary of the invention
The present invention seeks to design a kind of hydraulic draw valve device of Labor-saving high-efficiency, to increase work efficiency.
Hydraulic draw valve device, it has a trapezoidal screw, and trapezoidal screw lower end is connected with hanging body by carrying on the back mother, on hanging body, with pin, is connected with coupler body; Trapezoidal screw middle part is provided with oil cylinder seat and oil cylinder, and plain thrust bearing is equipped with on trapezoidal screw top and be positioned at rotation set on oil cylinder and have nut in nut, and nut is fixed with handle outward.
Advantage of the present invention is to adopt trapezoidal thread, has increased moment of torsion, increases plain thrust bearing in the middle of nut simultaneously, and firmly easily, rotation flexibly.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention (profile).
Fig. 2 is structural representation of the present invention (cutaway view).
Fig. 3 is Fig. 1 top view.
The specific embodiment
As Fig. 1-3 have provided the specific embodiment of the invention.Hydraulic draw valve device, it has a trapezoidal screw 3, and trapezoidal screw 3 lower ends are connected with hanging body 2 by carrying on the back female 8, on hanging body 2, with pin 7, are connected with coupler body 1; Trapezoidal screw 3 middle parts are provided with oil cylinder seat 4 and oil cylinder 5, and plain thrust bearing 10 is equipped with, the outer handle 9 that is fixed with of nut 6 in trapezoidal screw 3 tops and be positioned at rotation set on oil cylinder 5 and have nut 6 in nut 6.
During work, catch on valve body cylinder sleeve, connecting fluid cylinder pressure, pressurization is in oil cylinder piston, and jack-up also promotes, and can pull up valve body and cylinder sleeve.
