Abstract
A strain clamp. The invention relates to an electric power fitting. The device is used for connecting a first lead and a second lead which form a certain included angle with each other, and comprises a tubular body used for connecting the first lead, a steel anchor and a drainage tube used for connecting the second lead; the steel anchor is fixedly arranged at one end of the tubular body and is used for connecting a first lead; the cross section of the drainage plate is I-shaped, and a first connecting hole is formed in the surface of the drainage plate; the upper end of the drainage tube is provided with a plate-shaped fork opening, the distance between the plate-shaped fork openings is matched with the thickness of the plate surface of the drainage plate, a connecting hole II is formed in the plate surface of the plate-shaped fork opening corresponding to a connecting hole I in the drainage plate, and the connecting hole I and the connecting hole II are connected through bolts. The invention is beneficial to the drainage of the strain tower sections in large-span areas, air ports and vibration frequent areas, is convenient and simple to assemble in high-altitude operation construction, has good contact area, and ensures the stability of large-current transmission.
Description
Technical field
The present invention relates to a kind of electric armour clamp, relate in particular to a kind of strain clamp.
Background technology
Strain clamp is widely used in defeated, power transformation line construction, is used for changing the direction of cable transmission.Known wire clamp mainly adopts two kinds of connected modes, and split connects with whole and is connected.In the prior art, the whole connection is that drainage tube is weldingly fixed on the wire clamp main pipeline, and this connected mode complex structure is operated very inconveniently, especially can bring a lot of troubles to the workmen when work high above the ground.It mainly is on the online clip main body pipeline drainage plate to be set that split connects, the drainage tube utilization is bolted on the drainage plate, this structure installs very loaded down with trivial details, and drainage plate adopts rigidity flat board, intensity difference mostly, dislike under the situation slightly at weather, may cause the fracture of drainage tube and wire clamp, cause accident, and the poorly conductive of dull and stereotyped drainage plate, the electric power transfer that is unfavorable for high-tension line causes unnecessary waste.
Summary of the invention
The present invention provides a kind of drainage tube and drainage plate to be connected firmly in order to overcome above defective, and the structural strength height conducts electricity very well, and can save the strain clamp of material simultaneously again.Help the big drainage that the strain tower section is often sent out in area, air port and vibration regional of crossing over, its work high above the ground construction is easy to assembly, simple, has the excellent contact area, guarantees the stability of big current delivery.
Technical scheme of the present invention is: a kind of strain clamp, be used to connect lead one and lead two in a certain angle mutually, and comprise tubular body, the steel anchor that is used to connect lead one, the drainage tube that is used to connect lead two; The steel anchoring is arranged on an end of tubular body surely, is used to connect lead one; It also comprises and is fixedly connected on the drainage plate of tubular body towards steel anchor one end, and the cross section of drainage plate is I-shaped, and drainage plate plate face is provided with the circular hole that can allow tubular body pass, and also is provided with connecting hole one on the drainage plate plate face; The drainage tube upper end is provided with tabular prong, and the spacing of tabular prong and drainage plate plate face thickness are suitable, and the connecting hole one on the plate face of tabular prong on the corresponding drainage plate offers connecting hole two, and connecting hole one, connecting hole two connect by bolt.
The width of spacing and drainage tube prong plate is suitable between described I-shaped drainage plate two floors.
The prong section of described drainage tube and drainage tube body coaxial line.
The prong section axis of described drainage tube and drainage tube body axis are 10～70 ° of angles.
Described bifurcated clamping plate rear end is provided with an elastic device.
Advantage of the present invention is: drainage plate can utilize welding or directly cast and form the double-sided belt reinforcement of one combination, and structural strength height, bifurcated clamping plate and drainage plate are connected firmly, and contacts more fully, conducts electricity very well, and the while can be saved material again.Help the big drainage that the strain tower section is often sent out in area, air port and vibration regional of crossing over, its work high above the ground construction is easy to assembly, simple, has the excellent contact area, guarantees the stability of big current delivery.
