The hook of ceases to be busy hanging groove, the relative position in trolley line hanging groove lower section is provided with slide opening, movable fixture along the vertical direction on holding clamp
Bottom be movable fixture that the slide bar slided up and down in slide opening, the upper end of slide bar are provided between slide opening and hook
Head, movable fixture head be provided with upwards with holding clamp on trolley line hanging groove relative engagement trolley line clamping slot, active card
Tool head is provided with the draw ring that is engaged with action bars pull bar with linking up with the outside of mated position, be provided with slide opening and be sleeved on slide bar
Stage clip one, the upper end of stage clip one is engaged with slide bar, lower end is engaged with holding clamp and forms upper elasticity to movable fixture, Gu
Determine fixture lower section and be provided with the lower end of upper end and holding clamp to be fixedly linked and adapter sleeve of the slip cap outside slide bar, fixing card
Several steel ball holes are enclosed circumferentially arranged with one on adapter sleeve side wall below tool, a diameter is separately installed with each steel ball hole big
In the steel ball of adapter sleeve sidewall thickness, a circle is provided with the slide bar outer wall that the position that is arranged with steel ball hole is slidingly fitted is connected
The annular steel bead groove being engaged with each steel ball, is provided with control set of the slip cap outside adapter sleeve, control below holding clamp
The upper end endoporus for making set is that the large diameter hole one that is engaged with each steel ball, the lower section of large diameter hole one are and adapter sleeve outer wall is slided
The dynamic small diameter bore for coordinating, the set inwall that controls between large diameter hole one and small diameter bore is the up big and down small guiding conical surface, small
It is large diameter hole two of the internal diameter more than small diameter bore that controlling below diametric hole covers endoporus, and the company of being sleeved on is provided with large diameter hole two
Stage clip two outside female connector, the bottom of adapter sleeve is provided with outer wall and is slidingly fitted with the large diameter hole two of control set and fixed peace
End set outside adapter sleeve lower end, the upper end of stage clip two and the control of the top of large diameter hole two cover inner face be engaged, under
Hold and be engaged with the upper surface of end set.
The solution have the advantages that：Can ensure to contact reliable between grounding wire clamp apparatus and trolley line using it, dislodging connects
Convenient ground wire is quick, is conducive to shortening the interruption maintenance time and improves operating speed, does not interfere with normal power supply.It is operated with
Convenient, service speed is fast, and operating method is simple, only needed to after being suspended on trolley line pull joystick will its hold tightly securely
On trolley line, contact solid and reliable between trolley line, swing will not be produced on trolley line again and slided, be conducive to reliability
Ground connection.Only need to pull grounding wire clamp apparatus to be opened on trolley line with action bars when being taken from trolley line, it is possible to easily
