Description

Technical Field

[0001] This utility model relates to the field of wire tensioner technology, and in particular to a wire tensioner for power transmission and transformation lines. Background Technology

[0002] A tensioner, also called a wire tensioner, is a device used in the construction and maintenance of power transmission lines to tighten them. The main function of a tensioner is to ensure that the power transmission lines are properly tensioned during the construction process, thereby maintaining the stability and safety of the lines.

[0003] Existing technologies, such as the utility model patent with publication number CN220122481U, disclose a power transmission line tensioner. This patent includes a fixed frame, with a rotating shaft rotatably connected to the inner wall of the fixed frame. Two ratchet wheels and a clamping frame are fixedly connected to the outer surface of the rotating shaft. Each ratchet wheel has a pawl engaged on its outer surface. A fixed seat is fixedly connected to the inner bottom wall of the fixed frame, and a retractable frame is fixedly connected to the upper surface of the fixed seat. A rotating frame is slidably connected to the outer surface of the retractable frame, and several identical sliding plates are slidably connected inside the retractable frame. This power transmission line tensioner, by setting up a fixed seat, rotating frame, retractable frame, sliding plates, a triangular plate, a sliding plate, and a locking post, can clamp wires of different thicknesses, further improving the efficiency of the device. Under the support of the fixed seat, the rotating frame rotates, causing the locking post to slide along the inside of the rotating frame. The sliding of the locking post causes the triangular plate and the sliding plate to slide along the inside of the retractable frame.

[0004] In daily use, it has been found that power transmission and transformation lines are a key component of the power system, responsible for the transmission and conversion of electricity, ensuring the supply and distribution of electricity from power plants to users. Wire tensioners for power transmission and transformation lines are devices used to tighten conductors during the construction and maintenance of power transmission lines. Typically, two wire tensioners are placed at each end of the power transmission and transformation line, and the line is stretched towards both ends by the wire tensioners to complete the tightening operation. However, tightening a single power transmission and transformation line requires the use of two wire tensioners, which leads to excessively long tightening time and a cumbersome process of tightening two wire tensioners. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, fastening a single power transmission line requires the use of two wire tensioners, which leads to excessively long fastening time for a single power transmission line and cumbersome steps of tightening two wire tensioners. Therefore, a power transmission line tensioner is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a power transmission and transformation line body, with an adjustment device on one side of the power transmission and transformation line body. The adjustment device includes two fixed clamps, both of which are slidably connected to one side of the power transmission and transformation line body. An adjustment block is fixedly connected to one side of each fixed clamp. A connecting rod rotatably passes through the inner wall of the adjustment block. The same adjustment clamp is fixedly connected to both ends of the arc surface of the connecting rod. Two connecting rods slidably pass through the inner wall of the adjustment clamp. The connecting rods slidably pass through the inner wall of the fixed clamp. A connecting ring is threadedly connected to the arc surface of the connecting rod. A connecting block is fixedly connected to one side of the adjustment clamp. A single bidirectional screw is threaded through the inner walls of the two connecting blocks. A force-applying rod is fixedly connected to the arc surface of the bidirectional screw.

[0007] The aforementioned components achieve the following effects: The transmission and transformation line itself is a crucial component of the power system, responsible for power transmission and conversion, ensuring the supply and distribution of power from power plants to users. The tensioners on the transmission and transformation line itself are devices used to tighten conductors during the construction and maintenance of transmission lines. Typically, two tensioners are placed at each end of the transmission and transformation line, stretching the line towards both ends to complete the tightening operation. However, tightening a single transmission and transformation line requires two tensioners, leading to excessively long tightening times and cumbersome steps. In this case, an adjusting device can replace the original tensioners to tighten the transmission and transformation line, improving both the tightening effect and speed, thereby reducing the workload for workers.

[0008] Preferably, the arc surface of the force-adding rod is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the arc surface of the force-adding rod.

[0009] The effect achieved by the above components is that when the double screw is rotated by the force-adding rod, the anti-slip groove on the force-adding rod can increase the friction on the surface of the force-adding rod, thereby improving the stability when using the force-adding rod.

[0010] Preferably, a guide block is fixedly connected to one end of the arc surface of the connecting rod, and the guide block is funnel-shaped.

[0011] The effect achieved by the above components is that when the connecting rod contacts the inner wall of the connecting ring, the guide block installed on the connecting rod can reduce the angle required for the two to contact, thereby increasing the speed at which the two contact.

[0012] Preferably, auxiliary rings are fixedly connected to both ends of the arc surface of the bidirectional screw.

[0013] The effect achieved by the above components is that when the bidirectional screw drives the connecting block to move, the auxiliary ring installed on the bidirectional screw can prevent the connecting block from directly contacting the bidirectional screw, thereby preventing wear caused by direct contact between the two.

[0014] Preferably, an auxiliary device is provided on one side of the fixed clamp. The auxiliary device includes a side plate, which is fixedly connected to the fixed clamp. A rotating rod is threaded through one inner wall of the side plate. A stop block is rotatably connected to one end of the arc surface of the rotating rod, and a rotating block is fixedly connected to the other end of the arc surface of the rotating rod. A plurality of auxiliary grooves are formed on the arc surface of the rotating block. Guide rods are fixedly connected to both ends of the stop block near the rotating rod. Both guide rods slide through the other inner wall of the side plate.

[0015] The effect achieved by the above-mentioned components is that when the fixed clamp and the adjusting clamp are fixed to the main body of the transmission and transformation line, the fixing effect of the fixed clamp and the adjusting clamp can be strengthened by the auxiliary device, thereby improving the stability of the connection between the fixed clamp and the adjusting clamp and the main body of the transmission and transformation line.

[0016] Preferably, a contact pad is fixedly connected to the side of the abutment block away from the rotating rod, and the cross-sectional dimensions of the contact pad are the same as those of the abutment block.

[0017] The effect achieved by the above-mentioned components is that when the abutment block comes into contact with the power transmission and transformation line body, the contact pad installed on the abutment block can increase the friction force when the abutment block and the power transmission and transformation line body come into contact, thereby improving the stability of the contact between the two.

[0018] Preferably, the guide rod is a titanium alloy rod.

[0019] The effect achieved by the above components is that the guide rod made of titanium alloy is less prone to deformation, and the guide rod that is not easily deformed will perform better under long-term use.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by operating the adjustment device, when it is necessary to tighten the transmission and transformation lines, the tightening work can be completed through the adjustment device. The adjustment device can reduce the time spent tightening the transmission and transformation lines and increase the speed of the tightening work.

[0022] In this invention, by operating the auxiliary device, when the fixed clamp and the adjusting clamp are connected to the transmission and transformation line, the connection stability between the fixed clamp and the adjusting clamp and the transmission and transformation line can be improved by the auxiliary device, thereby further improving the fixing effect of the fixed clamp and the adjusting clamp on the transmission and transformation line.

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0029] Reference Figures 1-4 As shown, this utility model provides a technical solution: a power transmission and transformation line tensioner, including a power transmission and transformation line body 1, an adjustment device 2 on one side of the power transmission and transformation line body 1, and an auxiliary device 3 on one side of the fixing clamp 201.

[0030] The specific settings and functions of its adjustment device 2 and auxiliary device 3 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting device 2 includes two fixed clamps 201, both of which are slidably connected to one side of the transmission line body 1. An adjusting block 202 is fixedly connected to one side of the fixed clamp 201. A connecting rod 203 rotatably passes through the inner wall of the adjusting block 202. The same adjusting clamp 204 is fixedly connected to both ends of the arc surface of the connecting rod 203. Two connecting rods 206 slide through the inner wall of the adjusting clamp 204. The connecting rods 206 slide through the inner wall of the fixed clamp 201. A connecting ring 207 is threadedly connected to the arc surface of the connecting rod 206. A connecting block 205 is fixedly connected to one side of the adjusting clamp 204. The inner walls of the two connecting blocks 205 are threaded... A single bidirectional screw 211 runs through the entire structure, and a force-applying rod 208 is fixedly connected to the arc surface of the bidirectional screw 211. The transmission and transformation line body 1 is a key component of the power system, responsible for the transmission and conversion of electricity, ensuring the supply and distribution of electricity from power plants to users. The tensioner of the transmission and transformation line body 1 is a device used to tighten the conductors during the construction and maintenance of transmission lines. Typically, two tensioners are placed at both ends of the transmission and transformation line body 1, and the tensioners pull the transmission and transformation line body 1 towards both ends, thus completing the tightening operation. However, tightening a single transmission and transformation line body 1 requires the use of two tensioners, which also leads to… The time required to tighten a single transmission line body 1 is too long, and the process of tightening two wire tensioners is cumbersome. In this case, the adjusting device 2 can replace the original wire tensioners to tighten the transmission line body 1, improving both the tightening effect and speed, thereby reducing the workload of workers. The arc surface of the force-adjusting rod 208 is provided with several anti-slip grooves 209, evenly distributed on the arc surface. When the force-adjusting rod 208 drives the bidirectional screw 211 to rotate, the anti-slip grooves 209 on the force-adjusting rod 208 increase the friction on its surface, thus improving stability when using the force-adjusting rod 208. The connecting rod 206 has a funnel-shaped guide block 210 fixedly connected to one end of its arc surface. When the connecting rod 206 contacts the inner wall of the connecting ring 207, the guide block 210 on the connecting rod 206 reduces the angle required for contact between the two, thereby increasing the contact speed. Both ends of the arc surface of the bidirectional screw 211 are fixedly connected to auxiliary rings 212. When the bidirectional screw 211 drives the connecting block 205 to move, the auxiliary rings 212 on the bidirectional screw 211 prevent the connecting block 205 from directly contacting the bidirectional screw 211, thus preventing wear caused by direct contact.

[0032] Reference Figure 4As shown in this embodiment: the auxiliary device 3 includes a side plate 31, which is fixedly connected to the fixing clamp 201. A rotating rod 32 is threaded through one of the inner walls of the side plate 31. A contact block 34 is rotatably connected to one end of the arc surface of the rotating rod 32, and a rotating block 35 is fixedly connected to the other end of the arc surface of the rotating rod 32. Several auxiliary grooves 36 are provided on the arc surface of the rotating block 35. Guide rods 33 are fixedly connected to both ends of the contact block 34 near the rotating rod 32. Both guide rods 33 slide through the other inner wall of the side plate 31. When the fixing clamp 201 and the adjusting clamp 204 are fixed to the power transmission line body 1, the auxiliary device 3 can be used to raise the fixing clamp 201 and the adjusting clamp 204. The fixing effect of 04 is reinforced, thereby improving the stability of the connection between the fixing clamp 201 and the adjusting clamp 204 and the power transmission line body 1 through the auxiliary device 3. A contact pad 37 is fixedly connected to the side of the abutment block 34 away from the rotating rod 32. The cross-sectional dimensions of the contact pad 37 are the same as those of the abutment block 34. When the abutment block 34 comes into contact with the power transmission line body 1, the contact pad 37 installed on the abutment block 34 can increase the friction when the abutment block 34 and the power transmission line body 1 come into contact, thereby improving the stability of the contact between the two. The guide rod 33 is a titanium alloy rod. The guide rod 33 made of titanium alloy is less prone to deformation. Under long-term use, the guide rod 33, which is not prone to deformation, has a better performance.

[0033] Detailed Instructions for Use: Connect the fixing clamp 201 to one side of the transmission line body 1. Then, within the adjusting block 202, rotate the adjusting clamp 204 via the connecting rod 203. The adjusting clamp 204 will then contact the transmission line body 1. Insert the connecting rod 206 from the adjusting clamp 204 into the fixing clamp 201. Then, rotate the connecting ring 207 on the connecting rod 206. The movement of the connecting ring 207 will fix the fixing clamp 201 and the adjusting clamp 204 onto the transmission line body 1. Then, rotate the bidirectional screw 211 within the connecting block 205. The movement of the bidirectional screw 211 will cause the two connecting blocks 205 to move towards each other. Thus, the connecting blocks 205 can drive the fixing clamp 201 and the adjusting clamp 204 to move, thereby securing the transmission line body 1.

[0034] The rotating rod 32 is rotated by the rotating block 35 on the side plate 31. The movement of the rotating rod 32 will drive the abutment block 34 to move. The movement of the abutment block 34 will make contact with the power transmission and transformation line body 1 along the direction of the guide rod 33. Thus, the stability of the contact between the entire regulating device 2 and the power transmission and transformation line body 1 can be improved by the contact between the abutment block 34 and the power transmission and transformation line body 1.
