Abstract
The utility model discloses secondary miniature bus cutting tongs, which comprise a movable cutting head and a fixed cutting head. A cutting edge of the fixed cutting head is backwards arranged in an open groove at the front end of a fixed handle. A movable cutting head opposite to the cutting edge of the fixed cutting head is arranged in a groove of the fixed handle in a sliding way. A striker opposite to the tail end face of the movable cutting head is arranged in the fixed handle at the rear end of the movable cutting head. The rear end of the striker is connected to a contact terminal of a miniature hydraulic cylinder which is fixed in a cavity on the middle section of the fixed handle. A pressure reduction button is arranged on the hydraulic cylinder. A power arm is vertically led out of the hydraulic cylinder towards the outside of the fixed handle. The upper end of the power arm is connected to a movable handle through a shaft. The inner end of the movable handle is connected to a bracket through a shaft, and the bracket is fixed together with the fixed handle. A layer of insulating sheath is fixed on the outer wall of each of the fixed handle and the movable handle. The hydraulic cutting tongs have the advantages of simple structure, convenience for carrying and operation and high safety performance.
Description
Technical field:
The utility model relates to a kind of tools for live working, the excising forceps of the little bus of particularly a kind of can be under charged situation safe and reliable cut-out transformer station's screen top secondary.
Background technology:
Transform in transformer station, in the extension project, run into the work of changing or increasing protection screen, wherein should how to cut off the little bus of screen top secondary safely and reliably through regular meeting, guarantee simultaneously powered operation equipment unaffected be to need the problem that solves.Owing to limit by field condition, cut-out work must be carried out under electriferous state, the little Bus cutting device of existing secondary, and because of its cutter head part is big, and insulation property are poor, so can't be used under electriferous state, cutting off the little bus of secondary.
Summary of the invention:
The purpose of the utility model provides a kind of can the pincers by little Bus cutting at the secondary of safe and reliable operation under the electriferous state.
The technical scheme of the utility model is accomplished as follows; It includes a dynamic cutter head and stationary knife head, it is characterized in that: the blade of stationary knife head is installed in the open recess of deciding the handle front end backward, in deciding the groove of handle, is slidingly fitted with a dynamic cutter head relatively with the blade of stationary knife head; Decide to align in the handle dynamic cutter head breech face in the rear end of dynamic cutter head a striker is installed; The rear end of striker is connected on the contact of a micro hydraulic cylinder, and hydraulic cylinder is fixed in the stage casing cavity of stationary knife handle, on hydraulic cylinder, is provided with the decompression button; Outside deciding handle, vertically leading to power arm on the hydraulic cylinder; The upper shaft of power arm is connected on the fixed handle, the fixed handle inner end be coupling one with decide to decide to be fixed with one deck insulating sleeve respectively on handle and the fixed handle outer wall on the support that handle fixes.This fluid pressure type excising forceps, have simple in structure, be convenient for carrying and operation, advantage that security performance is good.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Embodiment:
Describe embodiment in detail in conjunction with accompanying drawing.This excising forceps are that the blade 1 with the stationary knife head is installed in the open recess of deciding handle 6 front ends backward; In the groove of deciding handle 2, be slidingly fitted with a dynamic cutter head 11 relatively with the stationary knife sword; Decide to align in the handle dynamic cutter head breech face in the rear end of dynamic cutter head a striker 3 is installed; The rear end of striker is connected on the contact of a micro hydraulic cylinder 4, and hydraulic cylinder is fixedly mounted in the cavity in stationary knife handle stage casing, on hydraulic cylinder, is provided with a decompression button 5; Outside deciding handle, vertically leading to a power arm 9 on the hydraulic cylinder; The upper shaft of power arm is connected on the fixed handle 8, the inner end of fixed handle be coupling one with decide to decide to be fixed with one deck insulating sleeve 7 respectively on handle and the fixed handle outer wall on the support 10 that handle fixes.During work; Earlier the little bus of secondary is placed in the slot opening of deciding the handle front end; With holding tight fixed handle and deciding the handle afterbody, power arm will make the oil pressure in the hydraulic cylinder increase again, promotes dynamic cutter head with striker and closes up to the blade of stationary knife head, safely the little bus copper rod of secondary is cut off.
