Abstract
The utility model discloses a tong-type ground-wire-connecting device including a small round plate, a large round plate and a round plate connecting rod arranged between the small round plate and the large round plate. A plurality of contact fingers are arranged on the peripheries of the small round plate and the large round plate uniformly. One ends of the touch fingers are fixed on the small round plates through fixing holes. Middle-rear ends of the touch fingers are supported by a contact finger groove of the large round plate and are then distributed in a 145-degree curved manner. Tail ends of the contact fingers are connected together fixedly through connection springs. Centers of the small round plate and the large round plate are on the same straight line. The round plate connecting rod arranged between the small round plate and the large round plate is provided with a connecting rod spring. The large round plate can move front and back along the round plate connecting rod. When the large round plate is moving towards the small round plate, all the touch fingers are stretchered outward in a radial pattern at the same time. One end of the round plate connecting rod is threaded in a connecting rod hole of the small round plate while the other end is threaded with a nut after penetrating through a connecting rod hole of the large round plate. By using the tong-type ground-wire-connecting device provided by the utility model, a problem that personal safety of maintenance workers is threatened and safety procedure is violated severely since maintenance technical measures cannot be performed when maintaining a built-in switch cabinet.
Description
Technical field:
The utility model relates to a kind of grounding wire device, particularly relates to a kind of handgrip type grounding wire device that is vertically mounted in cylindrical sleeve.
Background technology:
at present domestic 6kV～35kV central switch cabinet, restriction due to its structure and space, be connected with bus to be connected by original isolating switch and change into the moving contact connection that fixing fixed contact is connected with dolly, its phase spacing is nearer, reduce to 115mm by the ordinary tap cabinet greater than 270mm, so just, have the following disadvantages: 1. due to spatial limitation, phase spacing is less, and before dynamic/static contact contact or the moment after separating can produce electric arc, in order to cut off electric arc, the place has installed an insulating sleeve additional at each contact, parallel shape is vertical to be fixed on panel and insulating sleeve is with contact, contact is installed on insulating sleeve inside, 2. parallel shape is vertical to be fixed on panel because insulating sleeve and contact are, and the insulating sleeve internal diameter is 107mm only, and the gap between insulating sleeve and contact only has 26mm, and its inner space is narrow and small, conventional earthing device can't be connected with contact, 3. because conventional earthing device can't be connected with contact, cause the repair apparatus safety measure to complete, cause power equipment can not complete the technical measures of maintenance when maintenance, serious breach of security technical regulation and the personal safety that threatens the maintainer, potential safety hazard is larger.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, simple in structure, easy to operate, functional and can complete power equipment at the handgrip type grounding wire device of when maintenance technical measures.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of handgrip type grounding wire device, contain roundel, big disk and the disk connecting rod between them, described roundel and big disk surrounding evenly are provided with several fingertips, described fingertip one end is fixed on roundel by the fingertip fixing hole, in fingertip, the rear end is 145 ° of bendings distributions after the fingertip recess supports of big disk, and described fingertip end is fixed together by linking springs; The center of described roundel and big disk point-blank, be provided with rod spring on disk connecting rod between described roundel and big disk, described big disk can move forward and backward along the disk connecting rod, when big disk moved to the roundel direction, described several fingertips were radial and outwards open simultaneously.
Described disk connecting rod one end spiral is arranged in the roundel tie rod holes, and the other end passes after the big disk tie rod holes together with nut is screwed in.
Described roundel is provided with the roundel link with respect to the other end of big disk direction.
Described roundel, big disk and fingertip are made by metal material.
Under certain External Force Acting, described big disk is to described roundel direction along traveling priority, but when external force disappears big disk self-resetting under the elastic force effect of rod spring, thereby reach firmly and contact combining closely of object.
The beneficial effects of the utility model are as follows:
The utility model solved 6kV～35kV central switch cabinet when electric power apparatus examination because not completing the serious breach of security technical regulation of service technique measure and threatening the problem of maintainer's personal safety, the technical measures loss of outage that causes not in place, equipment loss, personnel's injury etc. when having avoided because of overhaul of the equipments, economic benefit and social benefit are obvious.
The utility model is simple in structure, and is reasonable in design, and the scope of application is wider, contained all central switch cabinets in 6kV～35kV scope.
The utility model is easy to operate, and is functional, and good looking appearance is cheap, tight with the combination that contacts object.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the Facad structure schematic diagram of fingertip in Fig. 1;
Fig. 4 is the Facad structure schematic diagram of roundel in Fig. 1;
Fig. 5 is the Facad structure schematic diagram of big disk in Fig. 1.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1～Fig. 5, in figure, 1-roundel link, 2-roundel, 3-fingertip, 4-big disk, 5-disk connecting rod, 6-fingertip linking springs, 7-roundel fingertip hole, the fixing hole of 8-fingertip in roundel, 9-big disk groove, 10-roundel tie rod holes, 11-big disk tie rod holes, 12-rod spring.
Embodiment: a kind of handgrip type grounding wire device, contain roundel 2, big disk 4 and the disk connecting rod 5 between them, evenly be provided with several fingertips 3 at roundel 2 and big disk 4 surroundings, fingertip 3 one ends are fixed on roundel 2 by fingertip fixing hole 12, in fingertip 3, the rear end is 145 ° of bendings distributions after the fingertip groove 9 of big disk 4 supports, and fingertip 3 ends are fixed together by fingertip linking springs 6; The center of described roundel 2 and big disk 4 point-blank, be provided with rod spring 12 on the disk connecting rod 5 between roundel 2 and big disk 4, described big disk 4 can move forward and backward along disk connecting rod 5, when big disk 4 moved to roundel 2 directions, all fingertips 3 all were radial and outwards open simultaneously; Disk connecting rod 5 one end spirals are arranged in roundel tie rod holes 10, it is rear together with nut is screwed in that the other end passes big disk tie rod holes 11, be provided with roundel link 1 at roundel 2 with respect to the other end of big disk 4 directions, wherein: roundel 2, big disk 4 and fingertip 3 are made by metal material.
