Description
Technical field
The present invention relates to high-voltage discharging rod technical field, particularly a kind of push-and-pull connecting-rod mechanism type safety high-pressure discharging rod.
Background technology
Along with the development of High-Voltage Technology, high-voltage discharging rod can carry out safety, stable electric discharge with it under high-pressure situations, becomes a kind of important managing security tools and instruments.In the inspection and maintenance process of high pressure equipment for power transmission and distribution, high-voltage discharging rod can carry out ground connection electric discharge to the transmission and distribution line cable that may there is dump energy, thus guarantee after power failure and overhaul affected before personal safety, the electric shock that to avoid residual charge is hurted sb.'s feelings event.General high-voltage discharging rod can stable discharging when low pressure, and electric wire can be ejected at any time when high pressure, cannot stable discharging, even affects personal safety.At present, there is not yet the discharging rod innovative design the be perfectly safe invention that a kind of structure is simple, be convenient to processing, low production cost.
Summary of the invention
The object of this invention is to provide a kind of push-and-pull connecting-rod mechanism type safety high-pressure discharging rod, which overcome the deficiency of existing high-voltage discharging rod, structure is simple, be convenient to processing, low production cost, safe electric discharge can be carried out under high-pressure situations.
The present invention achieves the above object by the following technical programs: a kind of push-and-pull connecting-rod mechanism type safety high-pressure discharging rod, comprise metal contact part, folding push mechanism and insulation rod portion, described metal contact part from metal contact body, metal contact connector, first metal clips and the second metal clips composition, metal contact connector is connected with metal contact main body by the first hinge, first metal clips is connected with metal contact main body with the second nut with the first nut and the second bolt by the first bolt, second metal clips is connected with metal contact connector with the 4th nut with the 3rd nut and the 4th bolt by the 3rd bolt.
Described folding push mechanism is made up of insulating support rod, insulation slide block and insulated connecting rod, insulation slide block set is on insulating support rod, insulation slide block can move on insulating support rod, insulating support rod upper end is fixedly connected with metal contact main body lower end by screw thread, insulated connecting rod is connected with metal contact connector by the second hinge, and insulated connecting rod is connected with insulation slide block by the 3rd hinge.
Described insulation rod portion is by the outer bar of supports insulative, the outer bar of handle insulation, bar in supports insulative, bar in handle insulation, cushion block and cushion block baffle plate composition, in supports insulative, bar upper end is fixedly connected with insulating support rod lower end by screw thread, in supports insulative bar lower end by screw thread and handle insulate in bar upper end be fixedly connected with, the outer bar upper end of supports insulative is fixedly connected with insulation slide block by screw thread, the outer bar lower end of supports insulative is fixedly connected with by screw thread and handle outer bar upper end of insulating, cushion block is enclosed within the outer bar end chute of handle insulation, cushion block can move on the outer bar end chute of handle insulation, cushion block baffle plate is fixed by the first screw and the second screw and the handle outer bar end chute that insulate, cushion block is wedge shape, the inclination angle on its inclined-plane is less than the angle of friction of its material therefor, promotion cushion block moves along chute and makes it to insert in the handle outer bar of insulation and the interior bar of handle insulation, moving downward of the restriction handle outer bar of insulation.
Push-and-pull connecting-rod mechanism type safety high-pressure discharging rod in use, inserts the earth connection plug prepared in the jack of metal contact main body, is connected by the other end of ground wire with the earth.Metal contact main body and metal contact connector are in released state, and namely metal contact part is in open mode.When push-and-pull connecting-rod mechanism type safety high-pressure discharging rod works, after electric wire enters metal contact part, in handle insulation, bar keeps fixing, the outer bar of driving handle insulation moves upward, then the outer bar of supports insulative and insulation slide block also move upward thereupon, insulation slide block promotes metal contact connector by insulated connecting rod and rotates to its and metal contact main body closing direction around the first hinge, thus realizes metal contact connector and metal contact main body is closed.Promotion cushion block moves along chute and makes it to insert in the handle outer bar of insulation and the interior bar of handle insulation, cushion block designs according to self-lock mechanism, the inclination angle, inclined-plane of cushion block is less than the angle of friction of its material therefor, no matter cushion block bears great vertical force, cushion block all can not eject, restriction handle insulation the moving downward of outer bar, thus realize fixing when metal contact connector and metal contact main body close.Now, push-and-pull connecting-rod mechanism type safety high-pressure discharging rod starts electric discharge.After electric discharge terminates, promote cushion block to move make it insulate with handle outer bar and the handle interior bar that insulate along chute and be separated, in handle insulation, bar keeps fixing, the outer bar of handle insulation is pulled to move downward, then the outer bar of supports insulative and insulation slide block also move downward thereupon, insulation slide block pulls metal contact connector to rotate to itself and metal contact main body detaching direction around the first hinge by insulated connecting rod, thus realize metal contact connector and metal contact body portion from, release electric wire, complete the whole course of work to electric wire electric discharge.
Outstanding advantages of the present invention is:
1, cushion block designs according to self-lock mechanism, cushion block is wedge shape, the inclination angle on its inclined-plane is less than the angle of friction of its material therefor, promotion cushion block moves along chute and makes it to insert in the handle outer bar of insulation and the interior bar of handle insulation, no matter cushion block bears great vertical force, cushion block all can not eject, moving downward of the restriction handle outer bar of insulation, thus realize fixing when metal contact connector and metal contact main body close, therefore, electric wire can not because of overtension automatic spring, effectively solve the problem that electric wire constantly ejects when electrion, improve stability and the fail safe of electric discharge, only need very little horizontal thrust, cushion block just can shift out from bar in the handle bar of insulation and handle insulation, is conducive to electric wire and easily puts into and release.First metal clips and the second metal clips all adopt elastic metallic material, are conducive to being engaged electric wire, are not easy to cut electric wire.
2, structure of the present invention simple, be convenient to processing, low production cost.In the design of folding push mechanism, have employed the folding that push-and-pull linkage common in theory of mechanisms realizes metal contact part, easy to use.
