[0002] The line tightener for power construction is used in power construction, which is mainly used for tightening, fixing and adjusting power cables during power line construction and maintenance, so that the cables reach appropriate tension and sag, ensure that the cables maintain a safe distance and correct form between the towers, prevent the cables from swinging, touching other objects or breaking due to excessive tension, and ensure the safe and stable operation of the power line, while improving the construction efficiency and facilitating the cable erection, connection and other operations of the construction personnel.

[0003] For example, the prior art with the application number CN202220532979.7 discloses a cable line tightener for power construction, which includes a lower clamp block, a lower protective pad fixedly connected to the lower clamp block, a cable in contact with the lower protective pad, a fixed rod fixedly connected to the lower clamp block, an upper clamp block slidably connected to the outer side of the fixed rod, the upper clamp block in contact with the lower clamp block, a limiting rod slidably connected to the inside of the upper clamp block, the limiting rod slidably connected to the fixed rod, a first spring provided on the outer side of the limiting rod, a limiting block fixedly connected to the limiting rod, and the limiting block in contact with the upper clamp block.

[0004] The above-mentioned prior art is known through actual use, which mainly clamps the cable through a single clamp plate. When the single clamp plate clamps the cable, the force point is relatively single. When the cable is subjected to tension, it is easy to cause uneven stress, resulting in cable shaking, deviation or even damage. Therefore, we improve the above-mentioned prior art according to the actual use. UTILITY MODEL CONTENTS

[0005] In view of the above problems, the utility model aims to provide a line tightener for power construction.

[0006] To achieve the technical purpose, the utility model provides a line tightener for power construction, which includes a support, a take-up roller rotatably arranged between the front and rear inner walls of the support, a steel rope peripherally arranged around the take-up roller, and a joint arranged at one end of the steel rope. The joint includes a square block and a clamp plate. One end of the square block is fixedly connected to the steel rope. A through slot is formed in the square block, and two movable clamp plates are arranged in the through slot. A bidirectional screw rod is rotatably arranged at one end of the square block to control the movement of the two clamp plates.

A connecting frame is fixed to the front side of the bracket by bolts, and a self-locking motor is fixed to the inner wall of the connecting frame. The output end of the self-locking motor is fixed to one end of the take-up roller via a connecting shaft to drive the take-up roller to rotate.

[0012] Beneficial effects:

[0013] 1. When using this device, one end of the cable is passed through the through slot in the connector, with the other end positioned between the two clamping plates. By turning the bidirectional screw, the two clamping plates can simultaneously clamp the cable. The simultaneous clamping of the cable by the two clamping plates applies force evenly from two directions, stably fixing the cable in the circular through slot, reducing cable swaying and displacement. Especially during cable pulling, it can better maintain the straightness and positional accuracy of the cable, providing stable clamping. At the same time, the two clamping plates move up and down simultaneously by turning the bidirectional screw, ensuring that the pressure on the circumference of the cable is more even during clamping, preventing damage to the cable's insulation layer or internal structure due to excessive local force.

[0014] 2. The two clamps are operated synchronously by a bidirectional screw. By turning the bidirectional screw once, the lifting and lowering of the two clamps can be controlled at the same time, so as to quickly clamp or loosen the cable, which greatly improves the operating efficiency and saves time and labor costs.

[0015] 3. When dealing with cables of different diameters and materials, the two-plate device can be adjusted more flexibly by precisely adjusting the clamping distance and force through the bidirectional screw to meet the clamping needs of various cable specifications. Attached Figure Description

[0021] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0022] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] like Figures 1 to 4 As shown, this embodiment of the invention provides a wire tensioner for power construction, including a bracket 1. A take-up roller 2 is rotatably arranged between the front and rear inner walls of the bracket 1, and a steel rope 3 is arranged around the take-up roller 2. One end of the steel rope 3 is fixed by casting or rope clamping, mainly used to fix the steel rope 3 to the take-up roller 2. A connecting member 4 is provided at one end of the steel rope 3. The connecting member 4 includes a square block 41 and a clamping plate 44. One end of the square block 41 is fixed to the steel rope 3. A through groove 42 is opened in the square block 41, and two movable clamping plates 44 are arranged in the through groove 42. A bidirectional screw 43 is rotatably arranged at one end of the square block 41 to control the movement of the two clamping plates 44.

[0024] refer to Figure 1A take-up roller 2 is rotatably mounted between the front and rear inner walls of the bracket 1 via bearings. A connecting frame 7 is fixed to the front side of the bracket 1 by bolts, and a self-locking motor 8 is fixed to the inner wall of the connecting frame 7. The output end of the self-locking motor 8 is fixed to one end of the take-up roller 2 via a connecting shaft to drive the take-up roller 2 to rotate. Two baffles 9 are integrally arranged in front and behind the take-up roller 2 to block the steel rope 3 and prevent the steel rope 3 from deviating during the winding process. A fixing rod 5 is rotatably mounted at one end of the bracket 1 via a pin. The fixing rod 5 is arc-shaped and can be used to be sleeved on the outside of the cable rack. The device is locked by a screw 6 inserted through one end of the two fixing rods 5.

[0025] refer to Figure 2 A U-shaped frame 47 is integrally provided at one end of the square block 41. The U-shaped frame 47 is fixed to the steel rope 3 by a pull ring. The outer surface of the pull ring is welded to the steel rope 3. The pull ring can be sleeved on the cylinder between the U-shaped frames 47. A bidirectional screw 43 is rotatably provided between the upper and lower walls of the U-shaped frame 47 through a bearing. The bidirectional screw 43 is threaded to the clamping plate 44. The two clamping plates 44 are positioned vertically opposite each other. The two sides of the clamping plates 44 are slidably provided with the through groove 42 through sliders. The opposing surfaces of the two clamping plates 44 are provided with arc-shaped grooves 45. The inner wall of the arc-shaped groove 45 is integrally provided with a protrusion 46. The protrusion 46 is hemispherical and is used to increase the friction with the cable and prevent the cable from slipping during the tightening process.

[0026] Working principle: When using this device, one end of the cable is passed through the through groove 42 in the connector 4, and one end of the cable is between the two clamping plates 44. Then, by turning the bidirectional screw 43, the two clamping plates 44 can clamp the cable at the same time. The two clamping plates 44 clamp the cable at the same time, which can apply force evenly from two directions, so that the cable is stably fixed in the circular through groove 42, reducing the shaking and displacement of the cable. Especially when pulling the cable, it can better maintain the straightness and positional accuracy of the cable and stably clamp the cable.

[0027] At the same time, the two clamping plates 44 are simultaneously moved up and down by the double-acting screw 43, which can ensure that the pressure on the cable circumference is more uniform during the clamping process, and will not damage the cable insulation layer or internal structure due to excessive local force.

[0028] The two clamping plates 44 are operated synchronously via a bidirectional screw 43. A single turn of the bidirectional screw 43 controls the simultaneous raising and lowering of both clamping plates 44, enabling rapid clamping or releasing of cables. This significantly improves operational efficiency and saves time and labor costs. For example, in scenarios requiring frequent cable replacement or adjustment, such as during equipment maintenance, this device can quickly complete cable clamping and releasing operations, improving maintenance efficiency.

[0029] When dealing with cables of different diameters and materials, the two clamping plates 44 can be precisely adjusted via the bidirectional screw 43 to flexibly adjust the clamping spacing and force, adapting to the clamping needs of various cable specifications. For example, in structured cabling projects, network cables and power cables of different thicknesses may be involved, and this device can better meet such diverse needs.

[0030] Finally, by starting the self-locking motor 8, the take-up roller 2 is rotated to wind up the steel rope 3, which in turn moves the square block 41 to pull the cable and complete the tensioning work.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
