At present grounding head mainly contains three kinds: the spiral and dual spring compression type of plain end screw type, round mouth.These three kinds of grounding heads exist following shortcoming:
Plain end screw type is screwing in process, puts forth effort gradually during along with spiral compression due to contact position place, and wire is easily shifted, and causes clamping place poor reliability; Dual spring compression type and spiral in the time blocking wire, all exist and cannot compress wire, easily cause contact-making surface inadequate, short circuit current is not up to standard, flicker easily occurs because the direction of grounding head is fixed, and can not operate by any direction, cannot meet the multidirectional operational requirements of switch cubicle, in practice process, often occurring because operator orientation of living in is not in vertical position with electric wire, think stablely while catching on electric wire when hand-held 2 meters of long earthing device, is part difficult work extremely; Because changing, direction of operating cause effective insulation distance inadequate; 220kv and above supertension line ground connection are installed especially difficulty, and potential safety hazard is very serious.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of easy to use, connect reliable Portable power construction grounding device.
The object of the present invention is achieved like this: a kind of Portable power construction grounding device, described device includes insulating bar, described insulating bar top is connected with shank (11) by universal joint, described shank top cross is provided with a top rail, on described shank, slide and be provided with a movable crosspiece, this movable transverse gear is in top rail below, and top rail parallels setting with movable crosspiece, have a vertical oil cylinder arranging to be fixed on shank, and the piston rod of oil cylinder is connected in the bottom of movable crosspiece.
A kind of Portable power construction grounding device of the present invention, described insulating bar is fixed with a ballhead, and described shank bottom is provided with a hemisphere draw-in groove embedding for ballhead, thereby has realized the universal hinging of insulating bar and shank.
A kind of Portable power construction grounding device of the present invention, described shank is vertically provided with rectilinear orbit, is provided with the slide block inserting in rectilinear orbit on described movable crosspiece.
A kind of Portable power construction grounding device of the present invention, the bottom of described top rail and the top of movable crosspiece all have the bayonet socket of curved setting, and the opening surface opposite of two bayonet sockets arranges.
A kind of Portable power construction grounding device of the present invention, is coated with the holding piece of a curved setting, and is connected with flexible member between bayonet socket and holding piece on described bayonet socket.
A kind of Portable power construction grounding device of the present invention, described flexible member is spring, and this spring one end is connected with the bottom of flexible member, and the other end is connected with the inwall of bayonet socket.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is by the design of universal joint, make angular adjustment convenient, thereby can make better laminating top rail of the present invention and movable crosspiece of cable, and by the bayonet socket design of top rail and movable crosspiece, further improve laminating contact effect, meanwhile, the holding piece covering on bayonet socket and flexible member make laminating more tight, increase the reliability connecting, improved security performance of the present invention.
