Abstract
The utility model discloses a clamp for ground wire end, comprising a main clamping head and a vice clamp. The vice clamp can move back and forth opposite to the main clamping head. The middle part of the vice clamp is fixed with a double-threaded rod. A cooperating double-nut is arranged outside the double-threaded rod. The external of the double-nut is fitted with the thread on the base of the main clamping head. The external of the base of the main clamping head is provided with a movably fixed sleeve and the interior is fixed with a threaded rod bottom sleeve. The interior of the threaded rod bottom sleeve is provided with a cardan universal joint. A rotating head of the cardan universal joint is sheathed with a movable circle fixed on a ball bearing. The external of the ball bearing is provided with a steel sleeve. A round connection strap at the external of the steel sleeve is movably fixed with a connection strap fixed on the sleeve. A shake off base is arranged on the shaft of the ball bearing. When rotating the shake off base, the threaded rod bottom sleeve is driven to rotate. After the double-threaded rod rotates in the double-nut, the main clamping head and the vice clamp move relatively. The clamp can clamp cables in different directions and different angles. It is easy in use and the performance of clamping is good.
Description
Technical field
The utility model uses a kind of specific purpose tool, specifically a kind of grounding terminal wire clamp when relating to a kind of electric power system, transmission line and converting equipment interruption maintenance.
Background technology
The grounding terminal wire clamp uses when being a kind of electric power system, transmission line and converting equipment interruption maintenance a kind of being used for the earthy clamping device of power failure equipments temporary short-circuit.The general at present stationary structure that adopts, can only be used for the clamping of horizontal alignment, can not adapt to that current power transmission circuit and power transformation circuit tilt, the requirement of use when vertical, and chucking power can not be regulated, can not guarantee that the electric contact in junction is good, use very inconveniently, complex operation, labour intensity are big, can not adapt to the needs of existing equipment maintenance.
Summary of the invention
The utility model provides a kind of grounding terminal wire clamp, and this wire clamp can be with different directions, different angles clamping cable, and easy to use, gripping performance is good.
A kind of grounding terminal wire clamp comprises main folder head and auxiliary splint, and auxiliary splint main folder head relatively moves around; The auxiliary splint middle part is fixed with a twin-screw, and twin-screw is provided with the double nut that matches outward, and double nut is outside to be cooperated with a main folder whorl of base; A main folder base exterior is provided with movable fixing sleeve pipe, cover at the bottom of the internal fixation screw rod, and cover inside is provided with a universal joint at the bottom of the screw rod; The rotary head of universal joint and the active ring socket that is fixed on the ball bearing; The ball bearing outside is provided with steel sleeve, and it is movable fixing with the brace that is fixed on the sleeve pipe that the steel sleeve outside has round brace; Have on the axle of ball bearing and shirk base, rotate and shirk base, cover rotates at the bottom of the drive screw rod, makes main folder head and auxiliary splint do relative motion after twin-screw rotates in double nut.
A described sleeve pipe and main folder base is movable fixing by the butterfly screw.
Described round brace is movable fixing by the butterfly screw with the brace that is fixed on the sleeve pipe.
Have steel ball in the described round brace, steel ball can roll on brace.
The utility model is by twin-screw, a main folder base, sleeve structure, make the retained part of front end can be in sleeve pipe rotation direction arbitrarily; Cooperate the folding that solves folder mouthful by universal joint, ball bearing, twin-screw, and make the relative rear portion of retained part of front end shirk base can to regulate direction arbitrarily; Movable fixing by the butterfly screw, can rotate by hand and fix, easy to operate.Whatsoever can both flexibly use in use by equipment, different directions, different angles for the utility model, guarantee difference, equipment, different directions, when different angles articulate line the electric contact in junction good, and meeting short circuit electricity notes effect moving down, heat-staple requirement, result of use is pretty good.
