DETAILED DESCRIPTION

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] In this technical solution, a tensioning device for electric power construction includes a fixed frame 1, which is cross-shaped. Fixed shafts 2 are installed on both sides of the fixed frame 1. A slide groove 3 is opened in the middle of the fixed frame 1. A sliding shaft 4 is slidably installed in the slide groove 3. Guide wheels 5 are rotatably installed on the outer sides of the fixed shaft 2 and the sliding shaft 4. The guide wheels 5 can fit the side walls of the external wires.

[0024] The guide wheel 5 includes a main side plate 51, a rotating sleeve 52, a threaded hole 53, a bolt 54, and a secondary side plate 55. The main side plate 51 is sleeved on the outside of the fixed shaft 2. The rotating sleeve 52 is rotatably mounted on the side wall of the main side plate 51. The side wall of the fixed shaft 2 is provided with a threaded hole 53. The bolt 54 is rotatably mounted in the threaded hole 53. The secondary side plate 55 is mounted on the outside of the bolt 54. The secondary side plate 55 can slide on the outside of the rotating sleeve 52.

[0025] The main side plate 51 and the secondary side plate 55 can clamp external wires;

[0026] In this technical solution, the wires are arranged above the two outer guide wheels 5 and below the middle guide wheel 5, and then the position of the sliding shaft 4 is adjusted to tighten the wires;

[0027] In order to make the device applicable to wires of various diameters, the auxiliary side plate 55 on the guide wheel 5 for clamping the wires is set to a sliding state. The position of the auxiliary side plate 55 can be adjusted by rotating the bolt 54, so that the auxiliary side plate 55 can limit the wires and prevent them from falling out.

[0028] In some technical solutions, a screw 6 is rotatably installed in the slide groove 3, a screw sleeve 7 is slidably installed on the outside of the screw 6, the sliding shaft 4 is installed on the side wall of the screw sleeve 7, and a motor 8 is installed in the inner cavity of the fixed frame 1. The motor 8 is electrically connected to the external power supply, and the output end of the motor 8 is inserted and installed in the slide groove 3 and connected to the screw 6.

[0029] In this technical solution, when tightening the wire, the motor 8 can be controlled to start, so that it drives the screw 6 to rotate, and the screw sleeve 7 starts to slide downward, thereby driving the guide wheel 5 outside the sliding shaft 4 to move downward, so that it presses down on the wire, thereby achieving the purpose of tightening the wire.

[0030] In some technical solutions, the bolt 54 includes a bolt body 541, a protective cover 542 and a connecting rod 543. The protective cover 542 is installed on the outside of the bolt head of the bolt body 541. The protective cover 542 can be inserted into the rotating sleeve 52. One end of the connecting rod 543 is installed on the side wall of the protective cover 542, and the other end of the connecting rod 543 is installed on the side wall of the secondary side plate 55.

[0031] In this technical solution, by providing a protective cover 542 on the outside of the bolt body 541, the bolt body 541 can be protected to prevent external dust or rainwater from coming into contact with the bolt body 541, thereby preventing the bolt body 541 from rusting and affecting the fit between the bolt body 541 and the threaded hole 53.

[0032] In some technical solutions, a cover cylinder 9 is further included. There are three cover cylinders 9 in total. The three cover cylinders 9 are respectively connected to the outer sides of the three guide wheels 5.

[0033] In this technical solution, the end of the bolt 54 in the guide wheel 5 is covered by the cover tube 9, which can further protect the bolt 54 and increase the aesthetics of the device.

[0034] In some technical solutions, a sealing ring 10 is installed on the side wall of the rotating sleeve 52 , and the sealing ring 10 can fit with the side wall of the protective sleeve 542 .

[0035] In this technical solution, the provision of the sealing ring 10 can improve the sealing performance of the connection between the protective sleeve 542 and the rotating sleeve 52, thereby preventing the entry of external dust or rainwater.

[0036] In some technical solutions, both the left and right inner walls of the slide groove 3 are fitted with shielding curtains 11, which are made of rubber.

[0037] In this technical solution, the function of the shielding curtain 11 is also to prevent the entry of external dust and rainwater and to prevent the screw 6 from rusting. The two shielding curtains 11 in this device are in contact with each other and can be in contact with the side walls of the sliding shaft 4. At the same time, the setting of the shielding curtain 11 does not affect the movement of the sliding shaft 4.

[0038] Working principle: When using this device to tighten external wires, first hang this device on the external wires, and make the wires above the two outer guide wheels 5 and below the middle guide wheel 5. Then, by starting the motor 8, it drives the screw 6 to rotate, causing the screw sleeve 7 to start sliding downward, thereby driving the guide wheel 5 outside the sliding shaft 4 to move downward, so that it presses down on the wires, thereby achieving the purpose of tightening the wires;

[0039] When the diameter of the wire to be tightened is large, the staff can remove the cover tube 9 and then adjust the position of the secondary side plate 55 by rotating the bolt body 541 to change the distance between the secondary side plate 55 and the main side plate 51 to make it slightly larger than the diameter of the wire to be tightened, thereby avoiding the wire from falling off the device during the process of tightening the wire by the device.
