Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0026] Example 1

[0027] Please refer to Figure 1-Figure 5 shown.

[0028] The utility model provides a U-shaped tension wire rack, which mainly solves the problems that the tension wire rack 1 in the prior art has low stability when clamping and fixing the cable; and the clamping and fastening process is complicated, which is easy to cause damage to the cable after long-term use, affecting the service life of the cable; in order to solve the above problems, a steel plate is pressed into a U-shaped tension wire rack 1 by hydraulic equipment and a mold, and an insulating coating is sprayed on the surface of the tension wire rack 1 and the surface of the clamping plate 2; the insulation performance of the equipment is ensured; the clamping plate 2 is the same length as the tension wire rack 1, ensuring that the clamping plate 2 has sufficient clamping surface to clamp and fix the cable in the U-shaped area of ​​the tension wire rack 1; the locking component can buckle the clamping plate 2 in the U-shaped area of ​​the tension wire rack 1, avoiding the clamping plate 2 from being pried along the extension direction of the tension wire rack 1 and failing to provide effective clamping force for the cable, and a protective component for protecting the cable is provided between the clamping plate 2 and the tension wire rack 1, which can avoid hard contact between the cable and the clamping plate 2 or the tension wire rack 1, thereby protecting the cable.

[0029] In some technical solutions of the utility model, the number of the locking components is at least one group, so that different clamping forces can be provided to the cable according to the needs, thereby improving the clamping effect of the device on the cable.

[0030] In some technical schemes of the utility model, the locking assembly includes a clamp 4, and claws 11 are provided on both ends of the clamp 4; locking grooves are opened on the opposite side walls of the two vertical sections of the tensioning frame 1 in the vertical direction, and the bottom of the locking groove is provided with a plurality of locking teeth 9 that are mutually engaged with the claws 11 in the vertical direction; when the clamp 4 is embedded in the two locking grooves, the claws 11 are placed between any two adjacent locking teeth 9. The clamp 4 is a steel metal spring sheet with good elasticity and toughness; the claw 11 is integrally formed with the clamp 4; the claw 11 is the bent section of the clamp 4 bent outward on the bending device; and the angle between the bent end and the clamp 4 is an acute angle; the angle between the locking tooth 9 and the locking groove is an acute angle; the use process of setting the locking assembly is: first embed one end of the clamp 4 between any two adjacent locking teeth 9 located in any locking groove, and then press the other section of the clamp 4 to make the claw 11 embedded between the locking teeth 9 in the other locking groove; the clamp 4 set in this way continues the above operation and alternates the operation so that the two ends of the clamp 4 gradually move toward the inner bottom wall of the tensioning frame 1 until they contact the top of the clamping plate 2, and apply a holding force to the clamping plate 2, so as to better fix the cable in the clamping area formed by the clamping plate 2 and the tensioning frame 1. And after the clamp 4 moves into place, the two ends of the clamp 4 are flush, ensuring that the holding force applied by the clamp 4 to the two ends of the clamping plate 2 remains balanced.

[0031] Preferably, the number of locking components is two or three groups; the top holding force can be applied to the head, tail and middle of the clamping plate 2, so as to avoid the problem that the clamping plate 2 buckled in the U-shaped area of the wire tensioning frame 1 is pried by external factors (the fluctuation of the wire and cable) along the extension direction of the wire tensioning frame 1; thereby improving the clamping effect of the device on the wire and cable.

[0032] Furthermore, it further includes a frame body 3 erected on the wire tensioning frame 1. A limiting rod 6 threadedly connected thereto is penetrated through the middle of the frame body 3, and a part of the limiting rod 6 is embedded in a clamping groove 12 opened on the outer top wall of the clamp 4. The frame body 3 is in a "C" shape, and both ends of the frame body 3 are fixed on the outer wall of the wire tensioning frame 1 by screws. Then, an internal threaded hole is opened in the middle of the frame body 3. The limiting rod 6 is a screw rod, and the screw rod cooperates with the internal threaded hole. At this time, the screw rod gradually moves towards the direction of the clamp 4 under the cooperation of the internal threaded hole until it abuts against the outer top wall of the clamp 4, applying a top holding force to the clamp 4, and cooperating with the clamping claws 11 to fix the clamp 4 in the wire tensioning frame 1. And a part of the limiting rod 6 is embedded in the clamping groove 12 opened on the outer top wall of the clamp 4, which can limit and lock the clamp 4 to ensure the normal operation of the device.

[0033] In some technical solutions of the present invention, a limiting groove is opened on one side of the inner bottom wall of the clamping plate 2背离 the wire tensioning frame 1, and limiting blocks 5 embedded in the limiting groove are provided at both ends of the clamp 4. The provided limiting groove is arranged along the width direction of the clamping plate 2; thus, after the clamp 4 abuts against the clamping plate 2, the two limits on the clamp 4 will be embedded in the limiting groove, preventing the clamping plate 2 from moving along the extension direction of the wire tensioning frame 1, which can limit and lock the clamping plate 2 by the clamp 4 to ensure the normal operation of the device.

[0034] In some technical solutions of the present invention, the protection component includes two pairs of protection ring bodies arranged in pairs. One of the protection ring bodies is arranged on the side wall of the clamping plate 2 opposite to the inner bottom wall of the wire tensioning frame 1, and the other protection ring body is arranged on the inner bottom wall of the wire tensioning frame 1. The provided protection ring body is a semi-circular rubber plate. Rubber has wear resistance and flexibility, and the actual length of the protection ring body is greater than the length of the addition plate or the wire tensioning frame 1. In this way, the outer layer of the wire and cable can be protected. After the clamping force applied by the clamp 4 to the wire and cable is too large, the wire and cable will not be damaged. And when the wire and cable expands, the two protection rings can be compressed, thereby providing a shrinking space for the wire and cable.

[0035] In some technical solutions of the present invention, an arc-shaped through groove is opened on the side wall of the clamping plate 2 opposite to the inner bottom wall of the wire tensioning frame 1. In this way, the wire and cable can be better accommodated, and a certain protection effect is achieved on the wire and cable.

[0036] In some technical solutions of the utility model, one end of the tensioning frame 1 is fixed with a mounting frame 7 by welding, and a mounting port adapted to the two vertical sections of the U-shaped connecting ring 8 is provided on the side wall of the mounting frame 7, and the two vertical sections of the U-shaped connecting ring 8 are provided with external threads, so that the nut can be screwed with the two vertical sections of the U-shaped connecting ring 8 to fix it on the fixing frame. Such a setting can also fix the structure on the hardware on the tension string group or the pole tower to ensure the stability of the device when it is fixed.

[0037] In some technical solutions of the utility model, the side of the mounting frame 7 away from the tensioning frame 1 is concave in an arc shape toward the tensioning frame 1; the side of the mounting frame 7 away from the tensioning frame 1 is provided with a concave-convex scratch 13. Such a setting can make the mounting frame 7 cooperate with the hardware on the tension string group or the pole tower, increase the release area of ​​the two and increase the friction force, and prevent the tensioning frame 1 from being displaced on the above-mentioned device after being affected by external factors.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
