Abstract
The invention discloses a quick puller for a temporary ground bar, and relates to a pullout device for a temporary ground bar. The lower portion of a sleeve pipe (12) is connected with the upper end of an upright (2) in a hinged mode through a shaft (3), the middle of a pressing rod (4) is arranged in the sleeve pipe in a penetrating mode, a handle is formed at one end of the pressing rod, a C-shaped support (13) is arranged at the other end of the pressing rod, M-shaped limiting protrusions (9) are arranged on the upper portions of the two sides of the C-shaped support respectively, and protruding rods (5) on the two sides of a lock ring are placed on the M-shaped limiting protrusions; the lock ring is formed by two semicircular locking plates (8) in a butt joint mode, side plates (6) are arranged on the two butt joint sides of the two semicircular locking plates and the side plates on the two semicircular locking plates are connected through screws (7). According to the quick puller, the two semicircular locking plates are used for clamping the ground bar, the ground bar can be pulled out quickly according to the lever principle of the pressing rod, and therefore the construction progress is quickened.
Description
[technical field]
The present invention relates to a kind of extracting apparatus of temporary grounding rod, especially relate to a kind of quick extractor of temporary grounding rod.
[background technology]
Known, transmission facility in electric power system, converting equipment, in the maintenance of wire or other power equipment, live line working is comparatively common, the said equipment in maintenance due to equipment or wire charged, must be provided with earthing device electric current is caused to the earth, to prevent that workmen from electric shock accidents occurring, the equipment that this process need is used is exactly earth rod, namely by dark being as far as possible driven underground of earth rod, the earth connection that connects earth rod is connected with repair apparatus or wire, form electric current and discharge path, yet after construction, the earth rod of being driven underground being taken out is a difficult problem, by rocking earth rod, make earth rod slack time very long and easily by earth rod bending, affecting secondary uses.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of quick extractor of temporary grounding rod, the present invention, by two semicircle jam plate clamping earth rods, just can extract earth rod fast by the lever principle of depression bar, and construction schedule is accelerated.
In order to realize described goal of the invention, the present invention adopts following technical scheme:
A kind of quick extractor of temporary grounding rod, comprise vertical rod, depression bar, sleeve pipe, the holder of C shape, lock ring and screw, the bottom of sleeve pipe is by the be articulated and connected upper end of vertical rod of axle, depression bar middle part is through in sleeve pipe, described depression bar one end forms handle, the other end of depression bar is provided with the holder of C shape, and two upper lateral parts of described C shape holder are respectively equipped with M shape spacing preiection, and the abutting stem of lock ring both sides is placed on M shape spacing preiection; Described lock ring is formed by two semicircle jam plate docking, in the docking both sides of two semicircle jam plates, is respectively equipped with side plate, and the side plate on two semicircle jam plates connects by screw.
The quick extractor of described temporary grounding rod, is provided with inner toothed surface on the trepanning forming at the inner face of two semicircle jam plates.
The quick extractor of described temporary grounding rod, is provided with the base of hole enlargement in the lower end of vertical rod.
Owing to having adopted technique scheme, the present invention has following beneficial effect:
The quick extractor of temporary grounding rod of the present invention, the present invention is fixed on earth rod in the lock ring of two semicircle jam plates formation by two semicircle jam plates and screw, by the C shape jacking on depression bar, live abutting stem, press moulded rod one end, under the principle of lever, just can extract fast earth rod, construction schedule is accelerated; Depression bar of the present invention also can be adjusted in sleeve pipe, during use, can to the complexity of extracting of earth rod, adjust depression bar according to soil property, has facilitated that workmen's extract earth rod fast.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the semicircle jam plate A of Fig. 1 is to view.
In figure: 1, base; 2, vertical rod; 3, axle; 4, depression bar; 5, abutting stem; 6, side plate; 7, screw; 8, semicircle jam plate; 9, M shape spacing preiection; 10, inner toothed surface; 11, trepanning; 12, sleeve pipe; 13, C shape holder.
[embodiment]
