Description

Traction Type Assembled Tension Clamp

technical field

The utility model relates to an electric device for anchoring conductors and ground wires in a power transmission line project, in particular to a traction-type assembled tension clamp.

Background technique

At present, the main method of laying out the transmission line construction is that the pulling end of the stranded wire is held by a net sleeve or a special pulling head tube, and after passing through multiple sets of pay-off tackles, after reaching the terminal of the tension section, the net sleeve or traction is removed. tube, and then replace the crimped strain relief. During these processes, the stranded wire falls to the ground many times, causing quality problems such as surface damage and burrs of the stranded wire are more common. The high-altitude operation of crimping tension clamps on the tower has a great safety risk. On the construction site, marking, cutting, and stranded wires have a large loss.

Contents of the invention

The technical problem to be solved by the utility model is to provide a traction-assembled strain clamp for the deficiencies of the above-mentioned prior art.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A traction-type assembled strain clamp, including a crimping tube, a steel anchor and a drainage clamp, one end of the crimping tube is connected to a stranded wire, and the other end of the crimping tube is connected to the steel anchor. The crimping tube is provided with a current contact surface, and the drain clamp is detachably connected to the crimping tube.

The crimping tube is also sheathed with a protective steel armor, the protective steel armor is in the shape of two semicircles, one end clamps the steel anchor, and the other end clamps the stranded wire through a pad.

The drainage clamp and the crimping pipe are detachably connected by fastening bolts.

The traction-assembled strain clamp of the present invention, the crimping tube and the drainage clamp can be detachably connected, the aluminum tube and the steel anchor clamp the stranded wire together, and a protective steel armor is set on the crimping tube, and the protective steel armor is two semicircular, One end clamps the steel anchor, the other end clamps the stranded wire through a pad, directly pulls the stranded wire through multiple sets of pay-off tackles, removes the protective steel armor, pads, etc., and then clamps the drainage wire with fastening bolts, gaskets, etc. Cooperate with the corresponding current contact surface of the aluminum tube and assemble into one body to meet its electrical performance requirements and complete the transmission of current.

Compared with the prior art, the utility model has the following advantages:

1. One-time crimping and traction construction of tension clamps reduces high-altitude operations and enhances personnel safety.

2. There is no need to re-break, strip, and crimp the wires, which reduces labor intensity.

3. Reduce the number of twisted wires falling to the ground and protect the surface of the twisted wires.

4. The loss of twisted wire is reduced.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail:

As shown in Figure 1, Figure 2, and Figure 3, the crimped aluminum tube 1 and the steel anchor 2 clamp the stranded wire together, and have the function of pulling the stranded wire, pulling the assembled tension clamp, and the steel pipe crimping position of the steel anchor 2 It can be at the steel anchor head; the aluminum tube 1 has a current contact surface, and its surface is matched with the drain clamp 3; a protective steel armor 6 is sleeved on the crimped aluminum tube 1, and one end of the protective steel armor 6 is embedded The pad 7 and the protective steel armor 6 are two semicircular shapes, one end clamps the steel anchor 2 and the other end clamps the pad 7 and the stranded wire to protect the aluminum tube 1 and the tension clamp composed of the steel anchor 2 is safe to pass the pulley without deformation; The aluminum pipe 1 has a current contact surface, and its surface is matched with the drain wire clamp 3 to connect.

When in use, the crimped aluminum tube 1 and the steel anchor 2 clamp the stranded wire 8 together, and a protective steel armor is set on it. Clamp the stranded wire, directly pull the stranded wire through multiple sets of pay-off tackles, remove the protective steel armor, pads, etc., and then use the fastening bolt 4, gasket 5, etc. to connect the drain wire clip 3 with the corresponding current contact of the crimped aluminum tube 1 The surface is matched and assembled into one body to meet its electrical performance requirements and complete the transmission of current.
