Abstract
The utility model provides an equalizing ring, comprising a metal cover and reinforcing ribs on the surface of the metal cover. The metal cover comprises two parts and the structure of the two parts is formed by integrating a sector plane and a semicircular plane. The top end of the semicircular plane is provided with a semicircular hole; the corner of the semicircular plane bends upwards and vertically; the corner bending upwards is provided with a hole; and one end part of the sector plane is fixedly connected with a convex U-shaped agraffe, and the other end is fixedly connected with a concave U-shaped agraffe. The equalizing ring is mounted by fixing the holes of the two parts correspondingly by a bolt and fixing the two U-shaped agraffes correspondingly. The two parts of the equalizing ring can be detached independently. The installation and the maintenance are convenient and the cost is saved.
Description
Technical field
The utility model relates to a kind of sub-assembly of power cable, a kind of annex that matches and use with power equipments such as post insulator, sleeve pipe, lightning arresters with circuit suspension type synthetic insulator and electric substation in the especially power transmission and transformation technical field.
Background technology
At present, general grading ring is the ring body of a closure, is installing, when changing, line need passed annular distance and install.In some occasions that need install additional or change, so just circuit need be cut off, install grading ring after, again circuit is connected, workload is very big, also needs other auxiliary gold utensils, the installation and maintenance inconvenience, cost increases; And grading ring all needs integral body is changed if fraction has bad phenomenon such as some are aging to produce slightly.
The utility model content
The utility model provides a kind of and can dismantle separately, installation and maintenance convenient, the grading ring of anti-bird pest.
In order to solve above technical problem, a kind of grading ring of the present utility model, the reinforcement that comprises metal cap, metal cap surface, its innovative point is: described metal cap divides two parts, its this two-part structure constitutes the open semicircle shape hole, top on described semicircle plane by sector and semicircle integral plane moulding.
The corner on described semicircle plane turns down vertically upward.
Have the hole on the corner of described upwards turnover.
Described sector one end end is fixedly connected with protruding U-shaped hasp, and the other end is fixedly connected with recessed U-shaped hasp.
Grading ring of the present utility model is made of after fixing the identical two parts butt joint of shape, structure, and need not during installation increases other standing finish in addition, has saved material; This grading ring can shirk separately simultaneously, and installation and maintenance are convenient, saved cost.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
As shown in Figure 1, 2,1 fen two parts of metal cap, these two parts constitute by sector 2 and semicircle plane 3 global formations.Semi-circular hole 4 is all left on described two halves circular flat 3 tops, and the corner of two halves circular flat 3 turns down vertically upward simultaneously, and symmetry has hole 5 on the corner of described upwards turnover; Described two sectors 2 one end ends are fixedly connected with protruding U-shaped hasp 6, and the other end is fixedly connected with recessed U-shaped hasp 7, and U-shaped shape center position all has hole 8.
When installing on the spot, two parts butt joint with metal cap 1, the circular hole that two semi-circular hole 4 form can be placed on the tubular part, and is fixing with the hole 8 of bolt with hole 5 and in the hasp 6,7 after cooperating respectively again, thereby the two-part sector 2 and the semicircle plane 3 of metal cap 1 is fastening.
Claims (4)
1, a kind of grading ring comprises the reinforcement on metal cap, metal cap surface, and it is characterized in that: described metal cap divides two parts, and its this two-part structure constitutes the open semicircle shape hole, top on described semicircle plane by sector and semicircle integral plane moulding.
2, a kind of grading ring according to claim 1, it is characterized in that: the corner on described semicircle plane turns down vertically upward.
