Abstract
Disclosed is a connecting rod type thread self-locking wire end ground clamp. One end of a main clamp body of the ground clamp and one end of an auxiliary clamp body of the ground clamp are fixedly connected with a main clamp head and an auxiliary clamp head, the middle of the main clamp body and the middle of the auxiliary clamp body are hinged through a hinge, the other end of the main clamp body and the other end of the auxiliary clamp body are hinged to an auxiliary connecting rod and a main connecting rod, and the main connecting rod and the auxiliary connecting rod are hinged together through a hinge. A thread control rod limiting block is hinged to the auxiliary connecting rod through a fifth hinge, a thread guide locking block is hinged to the main connecting rod through a hinge, and the thread control rod is matched with the thread guide locking block through a spiral pair. According to the ground clamp, the problems that a traditional clamp mechanism is complex in structure and unfirm in clamping are solved, construction and operation are easier, more convenient and safer, workloads of detection personnel can be effectively reduced, and working efficiency is improved.
Description
Technical field
The present invention relates to high-voltage conducting wires service kit, especially link-type screw thread self-locking wire end earthing clamp.
Background technology
Wire end earthing clamp is a kind of for by the safety appliance of transmission pressure temporary short-circuit ground connection having a power failure, and its effect is when to high voltage electricity transmission conductive wire interruption maintenance, prevents that suddenly incoming call or contiguous high voltage alive equipment produce the harm of induced voltage to human body.The wire clamp that current each grid company is used mainly contains double tongue type, flat, impacting type and spiral.But for 500kV circuit, front 3 kinds of cable clamp structures are not too reasonable, very easily come off and make working point lose protection.Can ensure reliable ground although spiral, use that its labour intensity is large, efficiency is low, operation is difficult, easily cause workmen sometimes not according to safety standard operation, have certain security risk.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of rational in infrastructure, ground connection is reliable, simple to operate, labour intensity is less link-type screw thread self-locking wire end earthing clamp.
Adopt following technical scheme for solving the problems of the technologies described above the present invention: a kind of link-type screw thread self-locking wire end earthing clamp, comprises wire clamp main body, linkage, screw thread joystick guide vane end stop, screw thread guide lock stops and screw thread joystick.Described wire clamp main body is made up of main line chuck, main line folder body, by-pass chuck and by-pass folder body, main line folder body, by-pass folder body one end are fixedly connected with main line chuck, by-pass chuck, centre is hinged by the 4th hinge, and the other end passes through the first hinge, the 3rd hinge and slave connecting rod respectively, master connecting-rod is hinged; Master connecting-rod, slave connecting rod are hinged by the second hinge; Screw thread joystick guide vane end stop is hinged on slave connecting rod by the 5th hinge, and screw thread guide lock stops is hinged on master connecting-rod by the 6th hinge; Screw thread joystick and screw thread guide lock stops coordinate by screw pair.Top and screw thread joystick guide vane end stop are by revolute pair matched in clearance.Power transmission line is: screw thread joystick-screw thread guide lock stops, screw thread joystick guide vane end stop-major and minor connecting rod-by-pass folder body, main line folder body-by-pass chuck, main line chuck-high-voltage conducting wires, turn screw thread joystick can be realized the quick opening and closing of wire clamp, and screw thread also has stable self-locking action simultaneously.
Described master connecting-rod bottom is provided with earth connection point.
Outstanding advantages of the present invention is:
Reliable to contact, ensure that safety is as starting point, in the situation that ensureing self-locking, in conjunction with and utilize screw thread joystick, linkage and folder body scissors-type leverage, just can reach wire clamp jaw travel and amplify, reduce the object of the spiral number of turns with reduction labour intensity.As long as turn joystick is expansible, closed chuck, thus complete fast high-voltage line clamping, unclamp action.Overcome traditional pure silk linkage wire clamp and rotated the number of turns too much or clamp not strongly solid problem, made more handy and safe of constructing operation, can effectively reduce testing staff's workload.
