Description
Technical field
The present invention relates to a kind of earthing clamp, especially relate to a kind of gravity self-locking formula Anti-dropping earthing clip.
Background technology
At present, known earthing clamp be " n " type and " C " type.Be divided into and on the wire of high-tension apparatus place, use and on bus bar, use two kinds.But these two kinds of earthing clamps all do not possess anti-drop function, in actual use, the dangerous and unstable potential safety hazard of installing.
Summary of the invention
In order to overcome the deficiency of existing earthing clamp, the invention provides a kind of gravity self-locking formula Anti-dropping earthing clip, this earthing clamp not only simple to operate, can be attached at any angle on wire or bus bar, and can prevent from coming off, guarantee that earth connection installs firmly.
The technical solution adopted for the present invention to solve the technical problems is:
Gravity self-locking formula Anti-dropping earthing clip, include: the two tongue fixing clampers of single hook, slide rail, movable locker, wire, insulation pull bar urceolus, insulation pull bar inner core, described slide rail internal upper part and bottom are respectively provided with a fast pulley, the upper end of the two tongue fixing clampers of single hook and earth connection is bolted the top at slide rail, the fast pulley of slide rail bottom is connected with U-shaped connector by knuckle screw, U-shaped connector is connected with insulation pull bar inner core, movable slider is embedded on slide rail in the slideway between two fast pulleys, on movable slider, be provided with castor, movable slider is connected with movable locker, insulation pull bar urceolus is sleeved on insulation pull bar inner core, the below that is positioned at insulation pull bar inner core in insulation pull bar urceolus is provided with insulated tube inner sealed board, the lower surface of insulated tube inner sealed board is provided with adjustment bolt, one end of wire is fixed on the upper end of slide rail, the other end of wire is connected on adjustment bolt after walking around successively castor and two fast pulleys, the bottom of insulation pull bar urceolus is provided with action bars interface.
On insulation pull bar urceolus, be provided with jig.
Advantage and effect that the present invention has are:
Wire clamp of the present invention is single two tongue tension-types employing cast aluminiums making that hooks, wire clamp is fixed on slide rail, two fixedly steamboats are installed on slide rail, movable locker is arranged on slide block, slide block is embedded in slide rail, on slide block, be provided with castor, wire one end is fixed on slide rail top, the other end is connected on the adjustment bolt of insulation pull bar after walking around castor and two fast pulleys, rely on elongation insulation pull bar length to make slide block drive activity locker increase, tightly by wire or bus-bar between earthing clamp and movable locker, earth connection installs, after insulating bar is removed, the weight of earth connection self can make movable locker pin wire or bus bar.While arranging site safety measure when high-tension apparatus has a power failure, use, can guarantee that earthing clamp is installed at any angle on wire or bus bar securely, can utilize the weight of earth connection self that earthing clamp is pinned, there is locking and anti-drop function, can only use insulating bar to remove, other any external force, wind-force and vibrations etc. all cannot cause earthing clamp to come off, and easy to operate, save time, can also guarantee the complete of operation field safety measure.And make earthing clamp can change setting angle by the employing of U-shaped connector.Solved the problem of earthing clamp single operation angle in the past.Guaranteed the firmly installing fast of operation field earth connection, unless used insulating bar to remove, any external force and vibration all cannot make earth connection come off, and have realized anti-drop function.Solved that known earthing clamp easily comes off, the problem of single operation direction, can guarantee the firmly installing fast of operation field earth connection, guaranteed operating personnel's safety.Omnirange operation, is used simply, safe and reliable, does not need to prepare in addition the earthing clamp of other models.
