Description

Assembled strain clamp low stress drainage device

Technical field

The utility model relates to power system transmission line technical fields, and it is low to specifically provide a kind of assembled strain clamp Stress drainage device.

Background technique

In transmission line construction, frequently encounter across high-speed railway, electric railway, important power circuit etc. it is important across More, property right unit is shorter and shorter across time requirement to transmission line of electricity, and conventional stringing technical matters process is more, and the duration is long, It is influenced by ambient weather, is unfavorable for the promotion of power grid construction ability.Assembled strain clamp, can be by tensioner, before unwrapping wire Crimping, conductor compression jointing time are not take up the unwrapping wire time, reduce unwrapping wire to the time of anchor support hanging wire, reduce across the time, Improve security reliability.Assembled strain clamp is different from common strain clamp structural shape, drainage device and strain clamp Main body is plug-in type installation, and existing drainage device not can guarantee its coming into full contact with strain clamp main body guide face, in turn The ducting capacity that not can guarantee electric current influences the security reliability of operation of power networks.

Therefore, how the improvement in structure is carried out to existing assembled strain clamp drainage device, to guarantee assembled The close contact of strain clamp drainage device guide face and strain clamp main body guide face, to guarantee assembled strain clamp Electric property becomes people's urgent problem to be solved.

Utility model content

In consideration of it, the purpose of this utility model is to provide a kind of assembled strain clamp low stress drainage device, with solution Certainly existing assembled strain clamp drainage device not can guarantee the close contact of its guide face and strain clamp main body guide face Problem.

Technical solution provided by the utility model is: a kind of assembled strain clamp low stress drainage device, comprising: drainage Wire clamp, wherein the conduction wire clamp is the board-like U-shaped wire clamp of duplex, is correspondingly arranged on the drainage plate of the conduction wire clamp two sides Drainage plate bolt hole corresponding with the limiting slot in strain clamp main body, the interior bottom of the conduction wire clamp is along its length It is provided with and subtracts power slot, for reducing the mount stress of conduction wire clamp.

It is preferred that the assembled strain clamp low stress drainage device further include be installed in the drainage plate outside plus Strong plate, is provided with stiffening plate bolt hole corresponding with drainage plate bolt hole in the stiffening plate, the drainage plate and reinforces Plate is bolted connection.

Further preferably, the drainage plate periphery is provided with edge, and the stiffening plate limit is set to the edge and surrounds Space in.

Further preferably, the drainage plate bolt hole is arranged at equal intervals.

Assembled strain clamp low stress drainage device provided by the utility model subtracts in the setting of the interior bottom of conduction wire clamp Power slot can reduce the mount stress of the drainage plate of conduction wire clamp two sides, make conduction wire clamp by subtracting the miniature deformation of power slot Guide face and the guide face of strain clamp main body come into full contact with, and increase water conservancy diversion area, ensure that current capacity.

Assembled strain clamp low stress drainage device provided by the utility model can effectively enhance the peace of operation of power networks Full reliability, reasonable in design, stable and reliable working performance are suitble to widely popularize in the industry.

Detailed description of the invention

With reference to the accompanying drawing and embodiment is described in further detail the utility model:

Fig. 1 is the assembling schematic diagram of assembled strain clamp low stress drainage device provided by the utility model；

Fig. 2 is the main view of conduction wire clamp；

Fig. 3 is the side view of conduction wire clamp.

Specific embodiment

The utility model is further explained below in conjunction with specific embodiment, but limitation is not originally practical It is novel.

As shown in Figure 1 to Figure 3, the utility model provides a kind of assembled strain clamp low stress drainage device, comprising: Conduction wire clamp 1, wherein the conduction wire clamp 1 is the board-like U-shaped wire clamp of duplex, right on the drainage plate 11 of 1 two sides of conduction wire clamp Drainage plate bolt hole 12 corresponding with the limiting slot in strain clamp main body 3, the drainage plate bolt hole 12 should be provided with Preferably it is arranged at equal intervals, the interior bottom of the conduction wire clamp 1 is provided with along its length subtracts power slot 13, for reducing drainage The mount stress of wire clamp 1.

The assembly method of the assembled strain clamp low stress drainage device is as follows: conduction wire clamp is plugged on strain clamp On the guide face of main body, using bolt after the limiting slot of the stiffening plate of two sides, drainage plate and strain clamp main body, nut is used It is fastenedly connected, conduction wire clamp guide face may be implemented by the fastening pressure of bolt and connect with the close of strain clamp main body guide face Touching, ensure that water conservancy diversion area and current capacity, enhances the security reliability of operation of power networks.

As the improvement of technical solution, which further includes being installed in the drainage The stiffening plate 2 in the outside of plate 11 is provided with stiffening plate bolt hole corresponding with drainage plate bolt hole 12 in the stiffening plate 2 (not shown), the stiffening plate can disperse the concentration compression for connecting bolt, make the concentration compression point for connecting bolt It dissipates in entire stiffening plate, keeps compression more uniform, meanwhile, the stiffening plate can also make the drainage panel stiffness of conduction wire clamp two sides It is strengthened.

As the improvement of technical solution, 11 periphery of drainage plate is provided with edge, and the limit of stiffening plate 2 is set to institute It states in the space that edge surrounds.

Specific embodiment of the present utility model is write according to progressive mode, and each embodiment party is highlighted The difference of case, similar portion can be with cross-reference.
