Description
Technical Field
The utility model relates to an electric power fitting field, concretely relates to adjustable tensioning clamp.
Background
The overhead transmission line is the most important mode for installing the transmission line, and in the overhead transmission line, a tensioning wire clamp for connecting the transmission line and a tower pole plays an important role and is a connecting hardware fitting for a line corner, a connection and a terminal. In recent years, along with the coming of the policy of environmental protection and the protection war of the blue sky, the NUT series of the original adjustable stay wire clamps adopt the production process of malleable cast iron, and the surface needs to be subjected to the anti-corrosion treatment by the hot galvanizing process, so that the pollution and the energy consumption are high, and the installation needs to be circularly rotated around the semi-circle of the wedge block. At present, the pull wire clamp NUT often causes inconvenient installation and is really hard because of the pulling force of the transmission line in the installation process.
SUMMERY OF THE UTILITY MODEL
The utility model provides an above problem, provide an installation laborsaving, save trouble, convenient and reliable's adjustable fastener.
The technical scheme of the utility model is that: including aluminum alloy main part and U type adjusting bolt, the both ends of aluminum alloy main part are equipped with the perforation respectively, in the perforation was located respectively to adjusting bolt's both ends, still include the clamp, a pair of voussoir and aluminum alloy seal end ball, the centre of aluminum alloy main part is equipped with the connecting hole, the clamp is established in the connecting hole, the clamp has and is conical jack, and a pair of voussoir sets up relatively, and connects in the jack, is equipped with the holding hole that is used for placing steel strand wires between a pair of voussoir, aluminum alloy seal end ball is used for sealing the end that steel strand wires are located adjusting bolt.
The section of the clamp body is frustum-shaped.
The section of the clamp body is rectangular.
And anti-skid teeth are arranged on the inner wall of the wedge block.
The utility model comprises an aluminum alloy main body, a U-shaped adjusting bolt, a clamp body, a pair of wedge blocks with anti-skid teeth and an aluminum alloy end sealing ball, wherein the aluminum alloy main body is provided with a pair of through holes, two ends of the U-shaped adjusting bolt are positioned in the pair of through holes, and the total length is adjusted by a nut; the clamp body is arranged in the connecting hole of the aluminum alloy main body, the pair of wedge blocks are arranged in the conical insertion holes of the clamp body, the steel strand is inserted into the accommodating hole between the pair of wedge blocks, the end of the steel strand is sealed and injected by the aluminum alloy sealing end, the end face of the steel strand is prevented from rusting, the steel strand is pulled back to enable the wedge blocks to bear force, and therefore the wire pulling on the power transmission line tower is tensioned.
The utility model discloses convenient processing, the operation is reliable.

Detailed Description
The utility model discloses as shown in fig. 1-5, including aluminum alloy main part 1 and U type adjusting bolt 2, the both ends of aluminum alloy main part are equipped with perforation 11 respectively, in the perforation was located respectively at adjusting bolt's both ends, still include clamp 3, a pair of voussoir 4 and aluminum alloy seal end ball 5, the centre of aluminum alloy main part 1 is equipped with connecting hole 12, clamp 3 is established in the connecting hole, the clamp has and is conical jack 30, and a pair of voussoir sets up relatively, and connects in the jack, is equipped with the holding hole 40 that is used for placing steel strand wires 6 between a pair of voussoir, aluminum alloy seal end ball is used for sealing the end that steel strand wires are located adjusting bolt.
In the work, the aluminum alloy main body is provided with a pair of through holes, two ends of the U-shaped adjusting bolt are positioned in the pair of through holes, and the total length is adjusted through the nut; the clamp body is arranged in the connecting hole of the aluminum alloy main body, the pair of wedge blocks are arranged in the conical insertion holes of the clamp body, the steel strand is inserted into the accommodating hole between the pair of wedge blocks, the end of the steel strand is sealed and injected by the aluminum alloy sealing end, the end face of the steel strand is prevented from rusting, the steel strand is pulled back to enable the wedge blocks to bear force, and therefore the wire pulling on the power transmission line tower is tensioned.
As shown in fig. 2, the cross section of the clip body 3 is frustum-shaped. Thus, the clamp body is detachably connected in the connecting hole.
As shown in fig. 1, the clip body 3 has a rectangular cross section. Therefore, the clamp body needs to be fixedly connected in the connecting hole and can be welded and connected.
And the inner wall of the wedge block is provided with anti-skid teeth 7. The anti-slip teeth are inverted teeth arranged on the hole surface. The aluminum alloy main body and the clamp body adopt a high-strength aluminum alloy low-pressure casting process, the strength of the product main body is higher through solution aging treatment, and the joint degree of the inner wall and the wedge block is better.
The wedge block is made of stainless steel through a tight hot forging process, the semi-circular arc-shaped surface for clamping the steel strand is provided with the anti-slip teeth with the barbs, the tooth-following wedge block is easy to enter when the steel strand is inserted, and the wedge block is pulled back to be clamped immediately after being in place, so that the installation is trouble-saving and convenient, and the effect of clamping the steel strand is firmer.
