Abstract
The utility model relates to hydraulic shears, which comprise a hydraulic device consisting of a hydraulic jack and a shear frame arranged on a jack cylinder cover (11). The hydraulic device comprises a pedestal (1) and an outer cylinder (12). The inside of the outer cylinder (12) is provided with a big hydraulic cylinder (3) and a big piston (5). The pedestal (1) is also provided with a small hydraulic cylinder, a small piston (14) and a compression rod (13) connected with the small piston. The big hydraulic cylinder (3) takes a shape of cylinder. An upper part of the big hydraulic cylinder is in threaded connection with the cylinder cover (11). The middle part of the cylinder cover (11) is provided with a convex edge. The convex edge fixes the outer cylinder (12) on the pedestal (1). The big piston (5) is sleeved with a return spring (4). The shear frame is fixed on the cylinder cover (11) and is divided into two upper and lower parts. The upper and lower parts are connected with each other by a movable pin roll. The hydraulic shears of the utility model have the characteristics of simple structure, labor saving and durability, can be applied to horizontal and vertical positions, and have more efficient and convenient use.
Description
Technical field
The utility model relates to hydraulic pressure to be cut, and belongs to the power line construction facility.
Technical background
Lead hydraulic pressure in the construction of existing power transmission and transformation line is cut, and is made up of hydraulic means and scissors, and the problem that its hydraulic means exists is easy leakage of oil, unreasonable structure, machining accuracy is not enough, cause use a period of time after, will overhaul.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, saves time with laborsaving, durable, and the hydraulic pressure that quality is high is cut.
The purpose of this utility model is finished like this, a kind of hydraulic pressure is cut, form by existing hydraulic jack hydraulic means that constitutes and the knife rest that is arranged on the jack cylinder cap 11, hydraulic means comprises base 1, urceolus 12, big hydraulic cylinder 3 and big piston 5 are set in the urceolus 12, between urceolus 12 and big hydraulic cylinder 3, form hydraulic fluid chamber.The depression bar 13 that also is provided with small cylinder and valve piston 14 on the base 1 and is connected with valve piston, oil pipe and check valve UNICOM by being provided with on the base between small cylinder and the big hydraulic cylinder 3, check valve is separately positioned on the bottom of small cylinder and big hydraulic cylinder, form by steel ball and pressing plate, also be provided with back-moving spring on the pressing plate.Can also be provided with drop handle on urceolus 12 outer walls, be convenient for carrying.
Big hydraulic cylinder 3 is a cylindrical shape, and the bottom is fixed on the base 1, and top is threaded with cylinder cap 11, cylinder cap 11 middle parts are provided with the convex edge, and the convex edge is fixed on urceolus 12 on the base 1, establish big piston 5 in the big hydraulic cylinder 3, big piston 5 bottoms are provided with sealing ring 2, are with back-moving spring 4 on the big piston 5.Bottom at the barrel of big hydraulic cylinder 3 can be provided with 1-5 spacing hole 15, and when the sealing ring 2 of big piston 5 rose to spacing hole 15, hydraulic oil will be discharged in the oil pocket, prevents the big piston 5 damage knife rest that rises too high.
Knife rest is fixed on the cylinder cap 11, and knife rest is divided into two parts up and down, and two parts are to be connected by active pin shaft up and down, and cutter is fixed on knife rest top, and bottom knife 6 is the top of big piston 5 fixedly, and moves up and down with big piston 5, and knife rest top also can be provided with stationary magazine creel 8.
The utility model hydraulic pressure is cut, be on the basis of the hydraulic means of existing hydraulic jack, to improve, its hydraulic means has simple in structure, laborsaving, durable characteristics, and on big piston 5, being with back-moving spring 4, convenient construction is because the check valve of the bottom of small cylinder and big hydraulic cylinder is provided with back-moving spring, the utility model hydraulic pressure is cut can construct horizontal, vertical position, uses more efficient convenience.
Description of drawings
Accompanying drawing is the utility model structural representation.
