Description

Technical Field

[0001] The invention relates to the technical field of electric power communication, in particular to a tension clamp capable of rapid positioning and installation. Background Art

[0002] Strain clamps refer to the hardware used to fix the conductors to bear the conductor tension and hang the conductors on the tension string group or pole tower. Strain clamps can be roughly divided into two categories according to the different structures and installation conditions. The first category: the tension clamps must bear the full tensile force of the conductors or lightning conductors, and the clamp gripping force is not less than 90% of the rated tensile force of the installed conductors or lightning conductors, but they are not conductors. This type of clamp can be removed after the conductors are installed and used separately. This type of clamps includes bolt-type tension clamps and wedge-type tension clamps. The second category: in addition to bearing the full tensile force of the conductors or lightning conductors, the tension clamps also serve as conductors. Therefore, once installed, this type of clamp cannot be removed again. It is also called a dead wire clamp. Since it is a conductor, the installation of the clamp must comply with the provisions of the relevant installation operating procedures and be carried out carefully;

[0003] Most existing transmission lines are usually installed with tension clamps, and the existing tension clamps have a simple structure, usually composed of a U-shaped sleeve and bolts that cooperate with each other to clamp and limit the cable body, and the bolts need to be tightened in turn;

[0004] When installing cables, existing tension clamps usually require the cables to be inserted into the tension clamps, and then the cables are clamped and installed by tightening bolts. When the tension clamps are in a harsh environment, the cable body is made of iron, which causes metal fatigue, resulting in corrosion and loosening of the cables. Therefore, some cables need to be inspected and maintained regularly by humans, which greatly increases manpower consumption. In addition, since the existing tension clamps have a relatively simple structure, most of the cables are exposed to the external environment, and the existing anti-corrosion method usually uses a protective cover, and the installation method of the protective cover is usually cumbersome. The wrong installation method greatly reduces the anti-corrosion effect, which has certain limitations. Summary of the invention

[0018] The beneficial effects of the present invention are:

[0019] When the tension clamp of the present invention is in a relatively harsh environment, the cable body inside the tension clamp is stretched due to environmental factors. Since a part of the cable body is wound around the outer wall of the reeling column, and the other end is limited between the first lower pressure plate and the clamping seat, the cable body between the reeling column and the clamping seat is straightened, and the reeling column can slide, and then the reeling column can be driven to rotate with the cooperation of the inner tube, the protrusion and the arc-shaped slide groove, so that the cable body can be reeled, which can effectively avoid metal fatigue caused by repeated stretching of the cable body and greatly extend its service life.

[0020] The present invention provides a sealing component. When the cable body is in a stretched state, the inner slide plate can slide with the cooperation of the contraction component. Then, with the cooperation of the piston rod, the piston body and the piston cylinder, the air inside the piston cylinder can enter the airbag body through the air guide tube, and the inside of the airbag can be inflated to fill the gap between the cable and the tension clamp. In addition, because the cable in a stretched state is usually in a relatively harsh environment, the expansion of the airbag body can effectively prevent the entry of external rainwater for corrosion. When the stretching is completed, the inner slide plate is reset under the action of the reset spring, and the airbag body is contracted. The external environment wind can dry the inside of the airbag, which can greatly delay the service life of the cable body and avoid the manpower consumption caused by frequent maintenance by the staff.

[0021] When installing the tension clamp of the present invention, the cable body can be wound around the outer wall of the reeling column, and then the other end of the cable body can be placed on the top of the clamping seat. At this time, the pull ring can be pushed. At this time, with the cooperation of the installation component and the limit component, the first lower pressure plate and the second lower pressure plate can be lowered at the same time, and their ends can be tightly attached to the outer wall of the cable body. When the threaded part is located at the bottom end of the threaded sleeve, the pull ring can be rotated to make the first lower pressure plate and the bottom end of the arc-shaped slide plate tightly attached to the outer wall of the cable body, thereby achieving the effect of installation limitation. At the same time, with the cooperation of the installation component, the protective cover can be driven to rotate, and the port part of the tension clamp can be closed. Most of the external corrosive substances can be isolated, and the corrosion of the cable body can be avoided, thereby achieving the effect of delaying its service life.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0045] A bottom slide groove matching the inner slide 404 is provided at the bottom end of the inner wall of the tension clamp 1, a rotating groove matching the port disk 403 is provided inside the inner slide 404, a winding rod 405 is located on one side of the inner slide 404, a plurality of groups of arc-shaped slide grooves 406-A are equidistantly distributed on the top of the lower fixed seat 406, two groups of protrusions 402-A are distributed in a circular array on the outer wall of the inner connecting tube 402, a winding groove matching the cable body 101 is provided on the outer wall of the winding column 401, a reset rod 4041 is fixed on one side of the outer wall of the inner slide 404, a fixed block 4042 is sleeved on the outer wall of the reset rod 4041, and a reset spring 4043 is fixed between the fixed block 4042 and the reset rod 4041.

[0046] Principle of this embodiment: When the tension clamp 1 is in a relatively harsh environment, the cable body 101 inside the tension clamp 1 is stretched due to environmental factors. Since a part of the cable body 101 is wound around the outer wall of the reeling column 401, and the other end is limited to between the first lower pressure plate 3021 and the clamping seat 301, the cable body 101 between the reeling column 401 and the clamping seat 301 is stretched straight, and the reeling column 401 can slide inside the tension clamp 1 under the pulling action of the cable body 101. When the inner connecting tube 402 fixedly connected to the reeling column 401 is in a sliding state relative to the lower fixed seat 406, the protrusion 402-A can slide in the arc-shaped slide groove 406-A opened at the top of the lower fixed seat 406, which can drive the reeling column 401 to rotate, and the stretched cable body 101 can be reeled in, thereby preventing multiple groups of cable bodies 101 from being entangled and knotted, avoiding metal fatigue caused by traditional fixing methods, and effectively avoiding metal fatigue caused by repeated stretching of the cable body 101, and at the same time greatly extending its service life.
