Abstract
The utility model relates to an electrification operation hydraulic shear which belongs to the technical field of design and manufacture of hydraulic shear for shearing high voltage power transmission line conductors. The upper part of an insulating rod is provided with a hydraulic shear head on which a transmission rod is arranged; and the transmission rod is provided with an insulating pull rope. The using method of the electrification operation hydraulic shear is as follows: an operator stands on the ground, lifts the insulating rod with hands, arranges a sheared conductor into a shear opening in a sheathing way, and then pulls the insulating pull rope with hands; the pull rope drives the transmission rod to enable a pressure column to add pressure to a hydraulic rod hole repeatedly, therefore, a lower shear edge of a hydraulic shear head slowly rises to be closed together with an upper shear edge, thus shearing the conductor; and after the operation is finished, a relief nut is opened, and the hydraulic shear opening restores to the normal state. Due to the arrangement of the insulating rod and the insulating pull rope, the electrification operation hydraulic shear can be operated without the application of power failure and can guarantee the normal power supply of the area of an upper construction part; and, due to the arrangement of the hydraulic shear head, shearing conductors is time-saving and labor-saving, and the working efficiency is improved.
Description
Technical field
The utility model belongs to the high voltage transmission-line line conductor and shears the design and the manufacturing technology field of cutting with hydraulic pressure.
Background technology
At present on high voltage circuit, be used for cutting off the operation of lead or wire jumper, cut with armstrong's patent usually or adopt the parallelogram transmission of insulating material manufacturing to cut.Must first to file have a power failure before adopting armstrong's patent to cut operation.Operating personnel carry mechanical shear must upward will need cut-off parts to cut off to lead.Adopt the parallelogram transmission to cut and then must not apply for having a power failure.Operating personnel must stand in ground or climb up shaft tower, and scissors are reached the enterprising line operate of lead.Because the volume of these two kinds of instruments is bigger, complex structure is operated and carries very inconvenient.No matter use which kind of tool operation, operating personnel will pay very big strength, greatly consume one's strength inefficiency.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of easy to operate lead hydraulic pressure and cuts, to solve the variety of issue that existing instrument brings.
Structure of the present utility model is as shown in drawings: a hydraulic pressure haircut is arranged on the top of insulating bar.One drive link is arranged on the hydraulic pressure haircut.One extension spring is arranged between hydraulic pressure haircut and drive link.On drive link, have the insulation stay cord.One compression leg is arranged on the lower end of drive link, and compression leg embeds in the hydraulic stem hole of hydraulic pressure haircut.Have the pressure release nut in the bottom of hydraulic pressure haircut.Using method of the present utility model is: operating personnel stand on the ground, hand is lifted insulating bar and will be inserted in the clip by the incisal guide line, then with pulling moving insulation stay cord, stay cord drives drive link makes compression leg exert pressure again and again to the hydraulic stem hole, the lower scissor blade of hydraulic pressure haircut is slowly risen and the upper scissor blade closure, lead is cut off.Open the pressure release nut behind the end of operation, the hydraulic pressure clip returns to normal.The utility model must not applied for when making operation having a power failure owing to have insulating bar and the insulation stay cord.Guaranteed the normal electricity consumption in construction epimere zone.In addition, because have the hydraulic pressure haircut, make that shearing lead becomes time saving and energy saving.Improved efficiency.
