A lightning arrester live-line test jointing clamp, includes inner tube, outer tube, jaw device, Self-unlocking device, and outer tube sleeve is loaded on outside inner tube, and Self-unlocking device is built in the inner chamber of inner tube,
Described Self-unlocking device includes unlock key, mechanism rack, tooth bar, release ratchet and pull bar, described unlock key is embedded in mechanism rack, unlock key is sleeved on tooth bar and the motion of lead agency support, unlock key one end is connected with a pull bar, the other end of unlock key is provided with inclined-plane, described release ratchet is for having flexible ratchet, one end of release ratchet is connected on pull bar, the other end is stuck in the middle of the sawtooth of tooth bar, and release ratchet is positioned at the place, inclined-plane of unlock key, on one end of mechanism rack, be provided with energy-stored spring, energy-stored spring is connected with the wire rope in jaw device,
Described jaw device includes slideway, upper jaw, lower jaw, travelling block, fixed pulley and return wheel, upper jaw is arranged on fixed pulley, lower jaw is arranged on travelling block, in return wheel, be provided with disc type energy-stored spring, fixed pulley, travelling block and return wheel are all arranged on slideway, return wheel and fixed pulley are fixed on the top and the bottom of slideway, travelling block is movably arranged in the slideway between return wheel and fixed pulley, between return wheel and lower jaw, by pulling-on piece or stay cord, be connected, also include wire rope, fixed pulley is fixed in described wire rope one end, the other end is walked around travelling block, after fixed pulley, form a pulley blocks, upper jaw and lower jaw when normality in open configuration,
Described slideway is connected with inner tube, and outer tube one end is set with on inner pipe, and the other end of outer tube is connected with extension rod, and the pull bar of Self-unlocking device is connected with extension rod;
On slideway, be also provided with binding post, described binding post and upper jaw conduct.
Lightning arrester live-line test jointing clamp of the present utility model, when needs are used, toward drop-down connecting link, connecting link drives outer tube motion, outer tube drives again coupled pull bar motion, the pull bar of motion moves by unlock key lead agency support, thereby drive the motion of the wire rope being connected with energy-stored spring on mechanism rack, after wire rope motion, what drive coupled travelling block does moving near fixed pulley along slideway, thereby realize, drive the lower jaw being arranged on travelling block to do the movement near upper jaw, to realize the clamping of bit, when loosen outer tube and on while pushing away, effect due to the pulling-on piece between travelling block and return wheel and the disc type energy-stored spring on return wheel, to drive lower jaw along slideway return, thereby realize opening of bit.
In sum, the utility model following advantage compared to existing technology:
Lightning arrester live-line test jointing clamp of the present utility model, can improve lightning arrester live-line test work efficiency, realizes the stable Leakage Current that obtains the arrester ground lead-in wire of flowing through, and improves lightning arrester live-line test data accuracy, owing to having added Self-unlocking device in jointing clamp, when connecting link drives outer tube drop-down, outer tube drives pull bar to move downward, the pull bar of motion drives unlock key to move down, the inclined-plane of unlock key front end and the angle of release ratchet are diminished, when outer tube pulls down while putting in place, angle between unlock key and release ratchet is 0 degree, thereby make release ratchet extend in tooth bar completely, thereby stuck tooth bar clamps bit firmly, when up pushing away outer tube, pull bar drives unlock key to move upward, the now inclined-plane lifting of unlock key, make release ratchet depart from tooth bar, realize release.
