Description
Technical Field
[0001] The utility model relates to the technical field of power transmission and transformation lines, in particular to a power transmission and transformation line tightener. Background Art
[0002] During the installation and maintenance of power transmission and transformation lines, line tightening operation is a vital task. Power transmission and transformation lines need to maintain appropriate tension to ensure their stable operation and safe and reliable power transmission. Traditional line tightening methods and tools often have some shortcomings. Some line tighteners may not be able to accurately control the tightening force during operation, which can easily cause the line to be too tight or too loose. Overtightening may cause the line to bear excessive tension, affecting its service life and even causing the line to break. Overloosening cannot guarantee the stability of the line and may cause it to shake under external forces such as wind, affecting the quality of power transmission and posing a safety hazard. In addition, existing line tighteners may lack effective anti-slip measures when in contact with the line. Therefore, we have introduced a new line tightener for power transmission and transformation lines. Utility Model Content
[0003] The main purpose of the utility model is to provide a power transmission and transformation line tensioner, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A power transmission and transformation line tensioner, comprising a fixed plate, a connection block fixedly connected to the left front end of the fixed plate, a movable device movably connected to the left end of the connection block, a pressing device fixedly connected to the rear end of the movable device, a pressing groove formed on the right side of the lower plate wall of the fixed plate, and an anti-slip layer fixedly connected to the pressing groove;
[0006] The movable device includes a sliding rod, the left end of the sliding rod is fixedly connected to the limiting block, the left end of the limiting block is fixedly connected to a ring, the left part of the outer surface of the sliding rod is sleeved with a buffer spring, and the sliding rod is movably connected to the left end of the connecting block.
[0007] Preferably, the clamping device includes a connecting plate, the upper front end of the connecting plate is fixedly connected to a No. 1 connecting shaft, the right front end of the connecting plate is inserted and connected to a No. 2 connecting shaft, the lower end of the connecting plate is fixedly connected to a compression block, the lower outer surface of the compression block is fixedly connected to a number of compression tooth blocks, and the connecting plate is located on the front side of the fixed plate.
[0008] By adopting the above technical solution: the compression block is used to directly contact and compress the line, and the compression tooth block at its lower part can increase the friction between the line and the line, so that the tensioner can clamp the line more firmly, thereby effectively performing the tensioning operation.
[0009] Preferably, the rear end of the No. 2 connecting shaft is movably connected to the front right part of the fixed plate through a bearing, and the front end of the No. 1 connecting shaft is fixedly connected to the rear part of the outer surface of the sliding rod.
[0010] By adopting the above technical solution: the No. 2 connecting shaft is connected to the fixed plate through a bearing, so that the connecting plate can flexibly rotate around the No. 2 connecting shaft. This design ensures that the clamping device can make precise angle adjustments according to the movement of the sliding rod, so that the clamping block and the clamping tooth block on it can accurately approach and clamp the line, ensuring the accuracy and effectiveness of the line tightening operation.
[0011] Preferably, the plurality of pressing teeth are arranged in an arc shape and are equidistant from one another.
[0012] By adopting the above technical solution: the arc-shaped compression teeth can better fit the shape of the transmission and transformation line. Since the transmission and transformation line is usually circular or approximately circular, the arc-shaped arrangement can make the compression teeth have a larger contact area with the line surface, thereby increasing friction.
[0013] Preferably, the compression block has a semicircular structure.
[0014] By adopting the above technical solution: during the line tightening process, it can more effectively utilize its own structural advantages to stably fix the line between the compression block and the fixing plate, further enhancing the clamping effect of the tensioner on the line, reducing the shaking and sliding of the line during the tightening process, and improving the stability of the tightening.
[0015] Preferably, the buffer spring is located on the left side of the connecting block.
[0016] By adopting the above technical solution: the buffer spring located on the left side of the connecting block can effectively play a buffering role. During the tightening operation, there may be a momentary large pulling force or pushing force. The buffer spring can absorb the energy generated by these external forces and reduce the impact of the external force on the device through its own elastic deformation.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. In the utility model, through the ingenious connection between the movable device and the clamping device, the movement of the sliding rod drives the clamping device to move, so that the line tightening operation can be precisely controlled. When the sliding rod is forced to move, the connecting plate is driven to rotate through the connecting shaft, so that the clamping tooth block and the pressing groove are accurately matched to clamp the line, avoiding the problem of the traditional tensioner's difficulty in accurately controlling the tightening force, preventing the line from being damaged by being too tight or too loose, and ensuring the stable operation of the transmission and transformation line and the quality of power transmission.
[0019] 2. In the utility model, a sleeve is used to connect the external structure to achieve preliminary and accurate positioning of the tensioner. The limit block prevents the sliding rod from excessive displacement, ensuring that the sliding rod moves stably within a certain range, thereby improving the overall reliability and safety of the device. The buffer spring undergoes elastic deformation under the action of external force, effectively buffering the impact of external force, which not only makes the tensioning operation process smoother, reduces line damage or device damage caused by instantaneous large force, but also extends the service life of the device. The semi-circular structure of the compression block and the arc-shaped compression tooth block can better fit the transmission and transformation line, increase the contact area, and improve the clamping effect and stability. The compression tooth blocks are arranged in an arc with equal distances, so that the line is evenly stressed, preventing local excessive pressure from causing damage to the line.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0028] See also Figure 1-4 , the utility model provides a technical solution:
[0029] A power transmission and transformation line tensioner includes a fixed plate 1, a connecting block 4 is fixedly connected to the left front end of the fixed plate 1, a movable device 3 is movably connected to the left end of the connecting block 4, a clamping device 7 is fixedly connected to the rear end of the movable device 3, a pressing groove 5 is opened on the right side of the lower plate wall of the fixed plate 1, and an anti-slip layer 6 is fixedly connected in the pressing groove 5.
[0030] In this embodiment, the movable device 3 includes a sliding rod 34, the left end of the sliding rod 34 is fixedly connected to the limiting block 32, the left end of the limiting block 32 is fixedly connected to the ring 31, the left part of the outer surface of the sliding rod 34 is sleeved with a buffer spring 33, the sliding rod 34 is movably connected to the left end of the connecting block 4, and the buffer spring 33 is located on the left side of the connecting block 4.
[0031] When the cam 33 is in the state of being moved, the stop block 32 at the left end prevents the cam 33 from being excessively displaced, thereby playing a limiting role. At the same time, when the cam 33 moves, it will drive the No. 1 connecting shaft 72 connected to the rear of its outer surface to move, and the buffer spring 33 sleeved on the left part of its outer surface will undergo elastic deformation under the action of external force, thereby playing a role in buffering external force and reducing the impact of instantaneous impact force on the entire device, making the device run more smoothly. The cooperation between the cam 33 and the stop block 32 ensures that the cam 33 can move stably within a certain range, thereby improving the reliability and safety of the device. The setting of the buffer spring 33 effectively buffers the impact of external force and prolongs the service life of the device. At the same time, it makes the line tightening operation process smoother and reduces the line damage or device damage caused by instantaneous large force.
[0032] In this embodiment, the clamping device 7 includes a connecting plate 71, the upper front end of the connecting plate 71 is fixedly connected to the No. 1 connecting shaft 72, the right front end of the connecting plate 71 is inserted and connected with the No. 2 connecting shaft 74, the lower end of the connecting plate 71 is fixedly connected to the compression block 75, and the lower outer surface of the compression block 75 is fixedly connected to a plurality of compression tooth blocks 73. The connecting plate 71 is located on the front side of the fixed plate 1, the rear end of the No. 2 connecting shaft 74 is movably connected to the right front end of the fixed plate 1 through a bearing, and the front end of the No. 1 connecting shaft 72 is fixedly connected to the rear outer surface of the sliding rod 34. The plurality of compression tooth blocks 73 are arranged one by one in an arc shape and at equal distances, and the compression block 75 has a semicircular structure.
[0033] With the above solution, the No. 1 connecting shaft 72 moves with the movement of the sliding rod 34. Since the rear end of the No. 2 connecting shaft 74 is movably connected to the right part of the front end of the fixed plate 1 through a bearing, the connecting plate 71 rotates with the No. 2 connecting shaft 74 as a fulcrum. The pressing block 75 at the lower end of the connecting plate 71 is a semicircular structure, and the plurality of pressing teeth 73 at the lower part of its outer surface are arranged in an arc with equal distances. When the connecting plate 71 rotates, the pressing teeth 73 approach the pressing groove 5 on the right part of the lower wall of the fixed plate 1, and finally cooperate with the pressing groove 5 to clamp. The power transmission and transformation lines, the semicircular structure of the compression block 75 and the arc-shaped compression tooth block 73 can better fit the power transmission and transformation lines, increase the contact area, and improve the clamping effect and stability. The arrangement of the compression tooth block 73 makes the line evenly stressed, preventing damage to the line caused by excessive local pressure. At the same time, the cooperation with the pressure groove 5 and the effect of the anti-slip layer 6 in the pressure groove 5 further enhance the clamping force and anti-slip performance of the line, ensuring that the line will not slide or loosen during the tightening process, thereby ensuring the effectiveness and safety of the tightening operation.
[0034] It should be noted that the present invention is a power transmission and transformation line tightener. During use, first, the tightener is initially fixed in a suitable position by the collar 31. When the line needs to be tightened, an external force acts on the sliding rod 34. Since the sliding rod 34 is movably connected to the left end of the connecting block 4, the limit block 32 and the collar 31 at its left end play the role of limiting and connecting to the outside. When the sliding rod 34 is forced to move, the buffer spring 33 sleeved on the left part of its outer surface is located on the left side of the connecting block 4, which will play a buffering role and reduce the impact of instantaneous impact force on the device. As the sliding rod 34 moves, it drives the No. 1 connecting shaft rod 72 fixedly connected to the rear of its outer surface to move, and the No. 1 connecting shaft rod 72 drives the connecting plate 71 to move. The rear end of the connecting shaft rod 74 is movably connected to the front right part of the fixed plate 1 through a bearing, so the connecting plate 71 will rotate at a certain angle with the No. 2 connecting shaft rod 74 as the fulcrum, and the semicircular compression block 75 fixedly connected to the lower end of the connecting plate 71 will move accordingly. A number of arc-shaped compression tooth blocks 73 fixedly connected to the lower part of the outer surface of the compression block 75 and arranged one by one at equal distances approach the compression groove 5 opened on the right part of the lower plate wall of the fixed plate 1. The compression groove 5 is fixedly connected with an anti-skid layer 6. When the compression tooth block 73 cooperates with the compression groove 5, it can tightly clamp the power transmission and transformation line. In this way, the line tightening operation of the power transmission and transformation line is realized. The cooperation between the compression tooth block 73 and the compression groove 5 and the effect of the anti-skid layer 6 are used to ensure the stability and safety of the line during the tightening process.
