Description
Technical field
The utility model relates to power overhead network technical field.
Background technology
Power circuit set up with maintenance process in, the connection between wire is inevitably, the processing mode connecting for same model wire, traditional way is to use hydraulic pressure splicing sleeve to connect it; And for the situation that occurs in track remodelling that both sides wire type is different, owing to can only using a kind of splicing sleeve to carry out the connection between wire, therefore can cause a side wire stable connection poor, for example carry out section transformation for 110kV circuit, newly-built line conductor model is LGJ-185/30, old line conductor model is LGJ-120/30, the wire of two kinds of different models can only use the splicing sleeve of 185/30 model to connect, therefore cause the connective stability of wire one side of LGJ-120/30 inadequate, can leave hidden danger to the safe operation of whole circuit.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of power overhead network reinforcement by connection device; simple in structure, connect fastening, easy to operate, install laborsaving, length is adjustable; reinforcement protection effect is played in terminal position, and then reduce the failure rate of whole circuit.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of power overhead network reinforcement by connection device, comprise the first arc plate and the second arc plate, the extrados middle part of the first arc plate and the second arc plate is fixed with respectively the first couple who is parallel to each other and is connected plate and is connected plate with second pair, first pair connects plate is connected plate with second pair all vertical with the axis of cambered surface, and first pair of connection plate is connected plate with second pair to be fixed with bolt after mutually pegging graft; First pair connects plate and second pair and connects between plate respectively through a preformed armor rods, and walks around respectively the first arc plate and be connected with left and right two parts of wire respectively with the second arc plate.
Described the second couple connects plate and inserts between first pair of connection plate.
On described the first couple connection plate or second pair of connection plate, be equipped with 2 above connecting holes, one of them is provided with 3 above connecting holes.
The beneficial effect that adopts technique scheme to produce is: in the utility model, preformed armor rods is walked around with the arc plate of cambered surface and is connected with wire, and preformed armor rods is played a very good protection, and avoids the wear and rupture of preformed armor rods, has increased the fail safe of power circuit; The utility model left and right two parts can regulate according to the length that connects terminal, strong adaptability.The utility model is simple and practical, length is adjustable, connect fastening reliable, simple to operation, install time saving and energy saving, make easily; the wire burn into bad connection that can prevent terminal position from connecting not firm, prolongation in time and to cause and the generation of the broken string that causes; reinforcement protection is played in terminal position; and then reduce the failure rate of whole circuit; and to reducing operating personnel's labour intensity, the safety that improves whole power circuit all has active influence, and has certain economic benefit.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 3, the utility model comprises the first arc plate 2 and the second arc plate 6, the extrados middle part of the first arc plate 2 and the second arc plate 6 is fixed with respectively the first couple who is parallel to each other and is connected plate 3 and is connected plate 5 with second pair, first pair connects plate 3 is connected plate 5 with second pair all vertical with the axis of cambered surface, first pair connect plate 3 is connected with second pair plate 5 mutually the rear bolt 8 of using of grafting fixes; First pair connects plate 3 and second pair and connects between plate 5 respectively through a preformed armor rods 1, and walks around respectively the first arc plate 2 and be connected with left and right two parts of wire 9 respectively with the second arc plate 6; Described the second couple connects plate 5 and inserts between first pair of connection plate 3; On described the first couple connection plate 3 or second pair of connection plate 5, be equipped with 2 above connecting holes 4, one of them is provided with 3 above connecting holes 4.
In the utility model, can also metallic channel be all set at the circumferencial direction of the extrados of the first arc plate 2 and the second arc plate 6, preformed armor rods 1 is walked around metallic channel and is connected, and the upper-lower position of preformed armor rods 1 is limited.
Preformed armor rods 1 is simple in structure, is easy to install, easy to use, stable performance, still can normally move running into extremely rugged environment, grip never discharges, without harmful stress concentration point, it can reduce dynamic stress, prevent that preformed armor rods 1 itself has certain anti-vibration functions, can improve the resistance to ability of shaking of wire 9 because disconnected burst phenomenon occurs fatigue of materials, preformed armor rods 1 itself can not produce to be concentrated the hurtful stress of wire 9, and practicality and connection are reliable.
In the utility model, to contact junction with the first arc plate 2 with the second arc plate 6 be cambered surface to preformed armor rods 1, cambered surface can not cause wearing and tearing to preformed armor rods 1, first pair connects plate 3 and is provided with 3 connecting holes 4, second pair connects plate 5 and is provided with 2 connecting holes 4, can be according to the length of terminal 7, adjust, reduce the pulling force that bear at terminal 7 positions, simple and practical, connect fastening reliable, simple to operation, it is time saving and energy saving to install, make easily, can prevent that terminal 7 positions from connecting not firm, prolongation in time and the wire corrosion that causes, bad connection and the generation of the broken string that causes, reinforcement protection is played in terminal 7 positions, and then reduce the failure rate of whole circuit, and to reducing operating personnel's labour intensity, the safety that improves whole power circuit all has active influence, and there is certain economic benefit.
