Abstract
The invention discloses a novel conducting wire end ground clip, which comprises a wire clip main body, an auxiliary wire clip, a control lever and a driving mechanism. By combining and using the control lever, a crank link mechanism and a scissors mechanism, the chuck stroke of the wire clip is amplified to fulfill the aim of reducing the spiral circles and reducing the labor intensity. A chuck can be opened and closed by only rotating the control lever so that clamping and loosening actions of a high-voltage cable are quickly finished. With the innovation, the problem of overmany rotating circles of a wire clip of the conventional pure screw rod mechanism is solved, so that construction operation is simpler and more convenient, and the workload of detection personnel can be effectively reduced. Besides, the novel conducting wire end ground clip meats the requirement of adjustable angle between the wire clip and the control level by using an angle adjustment positioning bolt and an arc limiting slot of a sector plate.
Description
Technical field
The present invention relates to the high-voltage conducting wires testing tool, especially a kind of Novel conducting wire end ground clip.
Background technology
Wire end earthing clamp is a kind of safety appliance of the transmission pressure temporary short-circuit ground connection for having a power failure, and its effect is to the high voltage electricity transmission conductive wire interruption maintenance time, prevents that unexpected incoming call or contiguous high voltage alive equipment from producing induced voltage to the harm of human body.The wire clamp of each grid company use mainly contains double tongue type, flat, impacting type and spiral at present.Yet for the 500kV circuit, front 3 kinds of cable clamp structures are not too reasonable, and very easily coming off makes the working point lose protection.Although spirally can guarantee reliable ground, use that its labour intensity is large, efficient is low, operation is difficult, easily cause the workmen sometimes not according to the safety standard operation, there is 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 Novel conducting wire end ground clip.
Adopt following technical scheme for solving the problems of the technologies described above the present invention: Novel conducting wire end ground clip, comprise wire clamp main body, by-pass folder, joystick and transmission mechanism, wire clamp main body one end is fanning strip, the other end is the main line chuck, middle by the connection of folder body, have the circular arc stopper slot on fanning strip, folder body top is installed with chute vertically, and folder body bottom is provided with earth connection point; The by-pass folder comprises by-pass chuck, push rod slide block and length adjustment screw rod, and the by-pass chuck is connected with length adjustment screw rod one end by revolute, and the length adjustment screw rod other end is connected with the push rod slide block by screw thread, and push rod slide block and chute are slidably matched; Transmission mechanism comprises scissors mechanism and toggle, scissors mechanism one end is connected by bearing pin with the push rod slide block, the scissors mechanism other end is fixedly connected with the crank end of toggle by the mandrel that is arranged on wire clamp main body through hole, and the connecting-rod head of toggle is connected by bearing pin with joystick; Be fixed wtih the angle adjustment bolt by the lock-nut activity in the circular arc stopper slot, angle adjustment bolt and joystick are threaded connection.
The angle adjustment bolt comprises connecting rod and screwed hole, and connecting rod passes the circular arc stopper slot and can move along the circular arc stopper slot, and screwed hole is fixedly connected with connecting rod and coordinates with the screw portion of joystick, and lock-nut coordinates with the screw portion of connecting rod.
5 degrees of freedom of chute restriction push rod slide block.
For the problem that traditional wire clamp exists, the present invention is reliable to contact, guarantee safety as starting point, the Novel conducting wire end ground clip of having used spiral self-locking and Designing Linkages.In the situation that guarantee self-locking, the present invention is in conjunction with also utilizing joystick, toggle and scissors mechanism, realizes that the wire clamp jaw travel amplifies to reach to reduce the purpose that the spiral number of turns reduces labour intensity.As long as rotating joystick is expansible, closed chuck, thus complete fast high-voltage line clamping, unclamp action.So innovation has overcome the too much problem of traditional pure silk linkage wire clamp rotation number of turns, makes constructing operation easier, can effectively reduce testing staff's workload.In addition, the present invention also utilizes the circular arc stopper slot of angle adjustment bolt and fanning strip to satisfy the adjustable requirement of angle between wire clamp and joystick.
