Abstract

A tightening clamp used for the traction of an aluminum stranded conductor with a carbon fiber composite core comprises an upper clamp, a lower clamp and a fastening device, wherein the upper clamp is positioned on the upper part of an amour rod, the lower clamp is positioned on the lower part of the amour rod, the upper clamp and the lower clamp circles the amour rod, the upper clamp is fixedly connected with the fastening device, and the fastening device is fixedly connected with the lower clamp. The tightening clamp used for the traction of the aluminum stranded conductor can effectively prevent the amour rod from sliding and achieve accurate positioning.

Description

Carbon fiber complex core aluminium stranded conductor traction comb-along

Technical field

The utility model belongs to the power circuit supporting apparatus, relates in particular to a kind of wire clamp.

Background technology

On the carbon fiber complex core aluminium stranded conductor, install and draw when using strain clamp; all to be installed on the lead protecting lines earlier; the traction strain clamp is installed again; play the effect of guardwire; but often in installation process, during the lead traction, lead is with protect between the lines can the generation sliding phenomenon; protect lines and just be difficult in the effect of playing guardwire on the accurate position, the defective of existence is: protect the easy slippage of lines, location difficulty.

Summary of the invention

In order to overcome existing carbon fiber complex core aluminium stranded conductor protects the easy slippage of lines, location difficulty when strain clamp is installed deficiency, the utility model provides a kind of and effectively prevents to protect the lines slippage, accurately the carbon fiber complex core aluminium stranded conductor of location draws and uses comb-along.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of carbon fiber complex core aluminium stranded conductor traction comb-along, comprise wire clamp, drop wire clip and fastener, the described wire clamp of going up is positioned at the top of protecting lines, described drop wire clip is positioned at the bottom of protecting lines, described upward wire clamp and drop wire clip surround the described lines that protect, the described wire clamp of going up is fixedlyed connected with fastener, and described fastener is fixedlyed connected with drop wire clip.

Further, described fastener comprises two U-bolts and four nuts, the described left and right sides of going up wire clamp is provided with bolt slot, the left and right sides of described drop wire clip is provided with bolt hole, described two U-bolts tightly are enclosed within respectively on two bolt slots of wire clamp, and passing two bolts hole of drop wire clip, spiro cap is contained in the bottom of U-bolt.

Further again, the junction of described nut and drop wire clip is provided with spring shim.

The beneficial effects of the utility model mainly show: before strain clamp is installed; to draw earlier with the comb-along clamping and protect lines; guarantee that thus aluminium stranded conductor aluminium stranded conductor can not take place and protects slippage between the lines in distraction procedure; protecting lines can accurately locate; play protection, improve safety of construction aluminium stranded conductor.

Description of drawings

Fig. 1 is the structure chart of carbon fiber complex core aluminium stranded conductor traction with comb-along.

Fig. 2 is the end view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

With reference to Fig. 1, Fig. 2, a kind of carbon fiber complex core aluminium stranded conductor traction comb-along, comprise wire clamp 1, drop wire clip 2 and fastener, the described wire clamp 1 of going up is positioned at the top of protecting lines, described drop wire clip is positioned at the bottom of protecting lines 2, described upward wire clamp 1 and drop wire clip 2 surround the described lines that protect, and the described wire clamp 1 of going up is fixedlyed connected with fastener, and described fastener is fixedlyed connected with drop wire clip 2.

Described fastener comprises two U-bolts 3 and four nuts 4, the described left and right sides of going up wire clamp 1 is provided with bolt slot 5, the left and right sides of described drop wire clip 2 is provided with bolt hole 6, described two U-bolts 3 tightly are enclosed within respectively on two bolt slots of wire clamp 1, and passing two bolts hole of drop wire clip 2, nut 4 is sleeved on the bottom of U-bolt 3.Described nut 4 is provided with spring shim 7 with the junction of drop wire clip 2.

In Fig. 1, do not draw and protect lines, to protect lines and be positioned at aluminium stranded conductor 8 outsides, the center of aluminium stranded conductor is a carbon fiber complex core 9.Before strain clamp is installed; elder generation is with the traction comb-along of present embodiment; promptly go up wire clamp 1, drop wire clip 2 and fastener clamping and protect lines; guarantee that thus the aluminium stranded conductor line aluminium stranded conductor can not take place and protects slippage between the lines in distraction procedure; protecting lines can accurately locate; play protection, improve safety of construction aluminium stranded conductor.
