[0001] The present application relates to the technical field of tensioning clamps, in particular to a wire end tensioning self-locking clamp. BACKGROUND

[0002] In the process of power construction, especially when setting up power transmission towers, erecting scaffolds or installing equipment on high supports, in order to increase the safety and stability of the erected power transmission towers, scaffolds or support frames, some building design specifications require the installation of a cable wind rope to ensure safety and stability.

[0003] The existing cable wind rope generally uses a steel wire rope, one end of which is fixed to a high power transmission tower, a construction scaffold or a high support, and the other end is installed on a hardened base through a mounting seat and at least one U-shaped fastener. The existing U-shaped fastener requires auxiliary tools to clamp and tension the steel wire rope during installation, and then the U-shaped fastener can be installed. It does not have the function of adjusting the tension of the steel wire rope, and at the same time, due to the influence of external factors such as rain in the outdoor environment, the installed U-shaped fastener is prone to bolt corrosion and steel wire rope sliding .

[0004] Based on the above problems, the present application provides a wire end tensioning self-locking clamp. SUMMARY

[0005] In view of the problems in the above technical background, the present application aims to provide a wire end tensioning self-locking clamp, which can adjust the tension of the cable steel wire rope during installation and maintenance, and can stably lock the installed steel wire rope after adjustment, solving the problem that the existing U-shaped fastener cannot adjust the tension of the cable steel wire rope during installation and is prone to bolt corrosion and steel wire rope sliding due to external factors.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] A wire end tensioning self-locking clamp, comprising a wire passing seat, a height-adjustable sliding frame is installed on the wire passing seat, a wire winding part is rotatably installed on the sliding frame, and the wire winding block included in the wire winding part is in the shape of an elliptic cylinder.

[0008] The adjustable height blocking piece is installed in the threading seat, the winding block is located between the blocking piece and the inner bottom of the threading seat, the reverse damping parts are installed on both sides of the winding block, one of the reverse damping parts is fixedly installed on the inner bottom of the threading seat, and the other reverse damping part is slidingly installed in the threading seat by a sliding frame; when the winding block rotates counterclockwise to collect the wire, the two reverse damping parts are pushed to shrink; when the winding block rotates clockwise, the two reverse damping parts are inserted into the winding block and the blocking piece and the winding block and the inner bottom of the threading seat, respectively, to lock the reverse rotation of the winding block.

[0009] In the above technical scheme, the winding block is installed in an elliptical cylindrical shape between the blocking piece and the inner bottom surface of the threading seat, the cable is wound on the winding block, the total width of the cable wound on the large diameter and both ends of the large diameter is less than or equal to the distance between the blocking piece and the inner bottom surface of the threading seat, and then the reverse damping parts are installed between the winding block and the blocking piece and between the winding block and the inner bottom surface of the threading seat at the entrances in the wire laying direction of the winding block. When the wire is laid in reverse, that is, the winding block rotates clockwise in reverse, the two reverse damping parts are inserted into the winding block and the blocking piece and the winding block and the inner bottom surface of the threading seat, respectively, to lock the reverse rotation of the winding block, and the greater the tension, the greater the reverse locking force. When it is necessary to increase the tension of the cable, the winding block is controlled to rotate counterclockwise in the forward direction, the steel wire rope is wound into the winding block during rotation, and the end is laid out in a spiral. Since the reverse damping parts are inserted into the winding block and the blocking piece and the winding block and the inner bottom surface of the threading seat on the reverse rotation side, the two reverse damping parts shrink under the action of the cable during forward rotation, that is, counterclockwise rotation, so the reverse damping parts do not lock the rotation of the winding block.

This installation method is simple in structure, has two reverse damping parts less than the above-mentioned installation structure which can be adjusted at any time, and can stably install the steel wire rope by using the tension of the steel wire rope after installation.

[0042] Design principle:

[0043] By rotating the winding block 410 between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210, the cable is wound on the winding block 410, the total width of the winding cable at the large diameter and both ends is less than or equal to the spacing between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210, and then the reverse damping part 600 is installed between the winding block 410 and the blocking piece 500 and between the winding block 410 and the inner bottom surface of the U-shaped seat 210 at the entrance, when the cable is wound and rotated, that is, the winding block 410 is counterclockwise reversed, the cable is squeezed and the reverse damping part 600 is elastically stretched, so that the two reverse damping parts 600 are respectively inserted into the winding block 410 and the blocking piece 500, the winding block 410 and the inner bottom surface of the U-shaped seat 210, and the reverse is locked, the greater the tension, the greater the reverse locking force; when the cable tension needs to be increased, the winding block 410 is controlled to rotate clockwise, the steel wire rope is wound into the winding block 410 in the rotating process, and the end is wound and released, because the reverse damping part 600 is inserted into the winding block 410 and the blocking piece 500, the winding block 410 and the inner bottom surface of the U-shaped seat 210 along the reverse rotating side, during the forward rotation, that is, counterclockwise rotation, the two reverse damping parts 600 are contracted under the action of cable extrusion, so the reverse damping part 600 cannot lock the rotation of the winding block 410, this structure can meet the needs of tightening the steel wire rope at any time by controlling the rotation of the winding block 410, without additional adjustment and cooperation, the function of controlling the steel wire rope tension by winding can be easily realized;

[0044] Meanwhile, the above structure also provides an installation mode, i.e. removing the two reverse damping parts 600, in places where some cable ropes are installed without the need for adjustment, the total width of the large diameter and the large diameter end of the winding block 410 is less than or equal to the distance between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210 before installation, and the tight line work is carried out, at this time the tight line strength is greater than the design requirement, and the pay-off after the winding block 90-degree reverse still meets the design requirement strength, i.e. after meeting the tension, the winding block 410 is continuously controlled to rotate so that the small diameter of the winding block 410 is between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210, then the blocking piece 500 is controlled to move towards the inner bottom surface of the U-shaped seat 210, so that the distance between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210 is less than the total width of the large diameter and the large diameter end of the winding cable, when the winding block 410 is rotated, the distance between the blocking piece 500 and the inner bottom surface of the U-shaped seat 210 is insufficient to provide a rotating space for the total width of the large diameter and the large diameter upper and lower outer sides of the steel wire rope, thereby the blocking piece 500 and the inner bottom surface of the U-shaped seat 210 clamp and rotate the steel wire rope and the winding block 410 to lock, this installation mode is simple in structure, but the installation and adjustment steps are relatively more, compared with the above installation structure which can be adjusted at any time, two reverse damping parts 600 are saved, the function of stable installation of the steel wire rope after installation can be realized by using the tension of the steel wire rope itself, and the user can select according to the use demand, i.e. tension adjustment frequency.
