Description

Technical Field

[0001] The invention relates to the technical field of power transmission equipment, and in particular to a tension regulating wire clamp for overhead transmission lines. Background Art

[0002] During the construction and operation of overhead transmission lines, the tension control of transmission lines is extremely important. Reasonable tension can ensure that the cables remain stable under different environmental conditions (such as temperature changes, wind force, line span differences, etc.), ensuring safe and reliable transmission of electricity. At the same time, the effective clamping of cables by wire clamps is not only related to the stability of transmission lines, but also involves safety issues such as preventing cables from slipping. Many existing wire clamp structures are relatively simple in design and lack an effective buffering mechanism. When encountering windy weather that causes cables to shake violently, or when the cable expands and contracts due to seasonal changes and causes a sharp change in tension, the wire clamp cannot buffer and absorb these instantaneous impact forces, which makes the impact force act directly on the cable and the wire clamp itself, which is easy to cause wear on the cable surface. Long-term accumulation may also cause damage to the internal structure of the cable, affecting Affecting its conductive performance and service life, some traditional wire clamps have problems of uneven clamping force or insufficient clamping stability when clamping cables. The clamping structure design of some wire clamps fails to fully consider the round appearance characteristics of the cable, and the contact area with the cable is limited, so that the clamping force is concentrated in a local area, which not only easily forms indentations on the cable surface and affects the cable strength, but also some existing wire clamps have limitations in the tension adjustment function. On the one hand, its adjustment range is narrow, and it is difficult to adapt to the changes in tension requirements of cables of different spans and specifications and in complex environments. When faced with sudden abnormal tension conditions, it is difficult to adjust in a timely and effective manner, resulting in the cable being in an unreasonable tension state for a long time, increasing the risk of cable failure and affecting the normal operation of the entire transmission system. Therefore, we introduce a tension adjustment wire clamp for overhead transmission lines. Summary of the invention

[0003] The main purpose of the present invention is to provide an overhead transmission line tension adjustment clamp, which can effectively solve the problems in the background technology.

[0004] To achieve the above object, the technical solution adopted by the present invention is: An overhead transmission line tension adjustment clamp comprises a bent long plate, one end of the bent long plate is fixedly connected to a fixed block, the other end of the fixed block is fixedly connected to an iron rope loop, a No. 1 rotating shaft is inserted and fixedly connected to the middle of the upper end of the bent long plate, the upper and lower parts of the outer surface of the No. 1 rotating shaft are both movably connected to a rear plate through bearings, and the upper front part and the lower front part of the bent long plate are movably connected to a tension device.

[0005] As a further improvement of the above scheme, the tension device includes a left rotating shaft rod, the upper outer surface and the lower outer surface of the left rotating shaft rod are fixedly connected with triangular plates, the middle upper ends and the middle lower ends of the two triangular plates are commonly movably connected with a movable component, the upper right ends and the lower right ends of the two triangular plates are commonly movably connected with a No. 3 rotating shaft, the upper ends and lower ends of the two No. 3 rotating shafts are commonly fixedly connected with a right plate, the upper rear end of the right plate is fixedly connected with a No. 2 rotating shaft, the front end and the rear end of the right plate are both provided with a No. 1 slide groove, the left end of the right plate is provided with a right outlet groove, the movable component and the right plate are fixedly connected with a buffer component, and the left rotating shaft rod is movably connected to the upper front end of the bent long plate.

[0006] By adopting the above technical solution: a relatively flexible and stable tension adjustment infrastructure is constructed by utilizing the connection relationship between the left-turn shaft rod, the triangle plate, the right plate and other components. The movable connection between the left-turn shaft rod and the bent long plate enables the entire tension device to rely on the connection point, and can flexibly rotate and deform when subjected to external forces, etc., providing a movable prerequisite for subsequent tension adjustment and related operations on the cable, and the connection and coordination between the components can better transmit and disperse the force, ensuring the reliability of the overall device under different tension states.

[0007] As a further improvement of the above scheme, the movable component includes a left plate, a left outlet groove is opened at the right end of the left plate, the middle part of the upper end and the middle part of the lower end of the left plate are fixedly connected with a No. 4 rotating shaft, the front end and the rear end of the left plate are opened with a No. 2 sliding groove, and the left plate is movably connected between the middle part of the upper end and the middle part of the lower end of the two triangular plates through two No. 4 rotating shafts.

[0008] By adopting the above technical solution: the left plate is movably connected to the triangle plate through the fourth rotating shaft, so that the movable component has flexible movement ability, so that it can make corresponding position changes relative to the triangle plate according to tension changes and other conditions. This movable connection method cooperates with other components of the entire tension device, so that when the cable tension changes, the movable component can adaptively adjust the state, thereby assisting in realizing effective clamping, buffering and other operations of the cable, ensuring that the entire wire clamp can better cope with different tension conditions and maintain stable operation.

[0009] As a further improvement of the above scheme, the buffer assembly includes a connecting plate, and a plurality of grooves are opened at the upper end and the lower end of the connecting plate, and a movable shaft rod is connected with a common bearing between the front groove wall and the rear groove wall of the plurality of grooves, and rollers are sleeved on the outer surfaces of the plurality of movable shaft rods, and the front end and the rear end of the connecting plate are fixedly connected with sliders, and the left end of the connecting plate is fixedly connected with a plurality of buffer springs, and the middle parts of the left ends of the plurality of buffer springs are interspersed with guide limit columns, and the right end of the connecting plate is fixedly connected with a safety component, and the connecting plate on the left side is located in the left plate on the left side.

[0010] By adopting the above technical solution: the connecting plate in the buffer assembly is provided with grooves, movable shafts, rollers and other components, which can make the relative movement between the components smoother and reduce friction and jamming, and the buffer spring and guide limit column can play a role in buffering and energy absorption when subjected to external force impact or tension changes, effectively reducing the instantaneous impact of tension changes on the entire device and the clamped cables, and avoiding problems such as damage to the device or loosening of the cables due to excessive impact force.

[0011] As a further improvement of the above solution, the safety component includes an insulating plate, a clamping groove is opened at the right end of the insulating plate, an anti-slip twill layer is fixedly connected in the clamping groove, and the insulating plate on the left side is fixedly connected to the right end of the connecting plate.

[0012] By adopting the above technical solution: the insulating board as a safety component, on the one hand, plays an insulating role, which can avoid safety hazards such as leakage in the environment of overhead transmission lines and ensure the safety of the device; on the other hand, the clamping groove and the fixed anti-slip twill layer can increase the friction between the cable, so that the cable can be clamped more firmly after the cable tension is adjusted, preventing the cable from slipping, etc., thereby ensuring the fixing effect of the cable.

[0013] As a further improvement of the above solution, the position and size of the insulating plate on the left side correspond to the position and size of the left outlet slot, and the position and size of the insulating plate on the right side correspond to the position and size of the right outlet slot.

[0014] By adopting the above technical solution: this corresponding relationship can ensure the position accuracy and adaptability of the insulating plate in the entire device structure.

[0015] As a further improvement of the above scheme, the two sliders on the left are respectively slidably connected in the two No. 2 slide grooves, and the two sliders on the right are respectively slidably connected in the two No. 1 slide grooves, the left ends of several guide limit columns on the left are fixedly connected to the left plate wall of the connecting plate, and the right ends of several guide limit columns on the right are fixedly connected to the right plate wall of the right plate.

[0016] By adopting the above technical solution: the sliding connection method between the slider and the slide groove limits the trajectory of relative movement between the components, ensuring that the buffer component can move and perform buffering actions smoothly in a predetermined direction when the cable tension changes, avoiding problems such as component deflection and misalignment.

[0017] As a further improvement of the above solution, the other ends of the plurality of guide limit posts are not in contact with the plurality of rollers, and the outer surfaces of the plurality of rollers are in contact with the upper plate wall and the lower plate wall of the left plate respectively.

[0018] By adopting the above technical solution: the contact between the roller and the upper and lower walls of the left plate, the rolling characteristics of the roller can be utilized when the buffer component moves relative to the left plate, which greatly reduces the friction and makes the movement of the buffer component smoother, helping to respond to tension changes more sensitively and efficiently, and realize buffering and corresponding adjustment functions.

[0019] As a further improvement of the above solution, the inner side of the insulating plate is an arc-shaped structure, and the insulating plate on the left has the same structure as the insulating plate on the right and is symmetrically distributed.

[0020] By adopting the above technical solution: the inner side of the arc-shaped insulating plate can better fit the round appearance of the cable, increase the contact area with the cable, so that the clamping force can be more evenly distributed on the cable surface, and cooperate with the anti-slip twill layer to further enhance the fixing effect of the cable.

[0021] As a further improvement of the above solution, the upper ends and lower ends of the two No. 2 rotating shafts are movably connected to the upper right parts and lower right parts of the two rear plates respectively.

[0022] By adopting the above technical solution: the movable connection between the No. 2 rotating shaft and the rear plate establishes a movable connection between the right plate and the rear plate. When the entire tension device is activated due to changes in cable tension, the right plate can perform appropriate rotation and other activities with the No. 2 rotating shaft as the axis, cooperate with the movement of other components in the device, and coordinate the change of the relative position and force state of each component, which helps to more flexibly and accurately adjust the tension and firmly clamp the cable, ensuring that the device can function normally under different working conditions.

[0023] As a further improvement of the above solution, the structure of the movable component is the same as that of the right plate and is symmetrically distributed left and right.

[0024] By adopting the above technical solution: this symmetrical and identical structural design enables the device to respond to tension changes in a balanced manner on the left and right sides. When clamping, buffering and adjusting the tension of the cable, the two sides can work synchronously and coordinately to ensure that the entire device is evenly stressed, avoiding problems such as uneven force, local excessive wear or functional imbalance caused by structural differences on both sides, thereby improving the overall stability, reliability of the device and the effectiveness of cable processing.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the buffer component plays a key role by arranging a groove on the connecting plate, connecting the movable shaft rod with a bearing and sleeved with a roller, so that the friction force is reduced when the connecting plate moves relative to the left plate or the right plate, the movement is smoother, and it can respond more sensitively to the tension change and quickly perform a buffering action. At the same time, the buffer spring is combined with the guide limit column. When impacted by external force, the buffer spring can use its own elasticity to absorb and buffer the impact force. The guide limit column limits the excessive deformation of the buffer spring and limits the moving range of the connecting plate. It can effectively buffer the impact force caused by sudden changes in cable tension and the like, avoid the impact force directly acting on the device and the cable, protect the cable surface from wear, prevent its internal structure from being damaged, maintain the cable's good conductivity and service life, and also reduce the fatigue damage of the wire clamp components due to frequent impacts, extend the service life of the wire clamp as a whole, and ensure the stable operation of the entire overhead transmission line system.

[0026] 2. In the present invention, by setting a safety component, the inner side of the insulating plate is in an arc-shaped structure and is symmetrically distributed on the left and right, which can fit the circular appearance of the cable well, so that the clamping force is evenly distributed on the circumference of the cable, avoiding damage to the cable due to excessive local force, and extending the service life of the cable. At the same time, the anti-slip twill layer fixedly connected in the clamping groove significantly enhances the clamping friction of the cable, ensuring that the cable will not easily slip off under tension, ensuring the firmness of the cable fixation, maintaining the stability of power transmission, and thus improving the stability of the entire transmission line, reducing the risk of safety accidents such as power transmission interruption caused by cable slippage, and ensuring the continuity of power supply.

[0027] 3. In the present invention, the tension device uses the left rotating shaft rod, the second rotating shaft, etc. as the rotating fulcrum, and the various components rotate and move relative to each other, driving the movable components to move in coordination, and the movable components are symmetrical and identical to the right plate structure, which can ensure that the forces on both sides are uniform and the movements are coordinated during the adjustment process, so that the entire tension adjustment process proceeds smoothly. At the same time, the structure can adapt to different tension conditions, effectively cope with the dynamic changes in the tension of the cable in actual use, ensure the normal operation of the entire transmission system, and improve the adaptability and operation efficiency of the overhead transmission line system to different working conditions.

[0035] Through the above scheme: the tension device 6 uses the left rotating shaft rod 61 as the movable connection point with the front part of the upper end of the bent long plate 3, the upper and lower parts of the left rotating shaft rod 61 are fixedly connected to the triangular plate 62, the triangular plate 62 is connected to the right plate 63 through the No. 3 rotating shaft 66, and the right plate 63 is movably connected to the rear plate 5 through the No. 2 rotating shaft 64. When subjected to external force such as cable tension changes, the left rotating shaft rod 61, the No. 2 rotating shaft 64, etc. are used as rotation fulcrums, and the various components rotate and move relative to each other, driving the movable component 65 to cooperate with each other to achieve the adjustment of the tension and cooperate with other components to perform corresponding operations on the cable. At the same time, since the movable component 65 and the right plate 63 have a left-right symmetrical and identical structure, it can ensure that the two sides are evenly stressed and coordinated during the adjustment process, so that the entire tension adjustment process is carried out smoothly. The left plate 651 is movably connected between the upper middle part and the lower middle part of the two triangular plates 62 through two No. 4 rotating shafts 652, and No. 2 slide grooves 653 are opened at the front and rear ends. A left slot 654 is provided at the end.

The active connection method between the components enables the device to adapt to different tension conditions, effectively cope with the dynamic changes in the tension of the cable in actual use, and ensure that the cable tension is within a reasonable range during power transmission. Its structural correspondence and coordination with the right plate 63 help to maintain the balance and stability of the entire device during operation, making the cooperation between the components closer and more orderly, thereby improving the overall performance of the device.

[0036] In this embodiment, the buffer assembly 69 includes a connecting plate 691, and a plurality of grooves 693 are formed at the upper and lower ends of the connecting plate 691. A movable shaft 694 is connected to the front and rear groove walls of the plurality of grooves 693 by a common bearing, and rollers 695 are sleeved on the outer surfaces of the plurality of movable shafts 694. The front and rear ends of the connecting plate 691 are fixedly connected to a slider 692. The left end of the connecting plate 691 is fixedly connected to a plurality of buffer springs 698. The middle parts of the left ends of the plurality of buffer springs 698 are interspersed with guide limit columns 697. The right end of the connecting plate 691 is fixedly connected to a safety component 696. The connecting plate 691 on the left is located in the left plate 651 on the left, the two sliders 692 on the left are respectively slidably connected in the two No. 2 slide grooves 653, and the two sliders 692 on the right are respectively slidably connected in the two No. 1 slide grooves 68. The left ends of the several guide limit columns 697 on the left are fixedly connected to the left plate wall of the connecting plate 691, and the right ends of the several guide limit columns 697 on the right are fixedly connected to the right plate wall of the right plate 63. The other ends of the several guide limit columns 697 do not contact the several rollers 695, and the outer surfaces of the several rollers 695 are respectively in contact with the upper plate wall and the lower plate wall of the left plate 651.

[0037] Through the above scheme: in the several grooves 693 opened at the upper end and the lower end of the connecting plate 691, the movable shaft rod 694 is connected through the bearing, and the outer surface of the movable shaft rod 694 is sleeved with the roller 695, so that when the connecting plate 691 moves relative to the left plate 651 or the right plate 63, the roller 695 can roll along the upper plate wall and the lower plate wall of the left plate 651, reducing the friction force and making the movement smoother. At the same time, the several buffer springs 698 connected to the left end of the connecting plate 691 will be compressed or stretched when subjected to external forces such as the impact force caused by the sudden change of tension, and use their own elasticity to absorb and buffer the impact force, and the guide limit column 697 inserted in the buffer spring 698 plays a role in limiting the excessive deformation of the buffer spring 698. The sliders 692 at the front and rear ends slide in the corresponding grooves to ensure the accuracy of the moving direction. The setting of the roller 695 effectively reduces the friction between the components in relative motion, so that the buffer assembly 69 can respond to the tension change more sensitively and quickly make a buffering action to ensure the efficiency of the tension adjustment of the device. The buffer spring 698 combined with the guide limit column 697 can effectively buffer the impact force caused by sudden changes in cable tension, avoid the impact force directly acting on the device and the cable, protect the various components of the device from damage, and prevent the cable from loosening, wearing and other problems due to excessive force at the moment, thereby improving the safety and stability of the entire wire clamp device and the cable system.

The inner side of the insulating plate 6961 is an arc-shaped structure, and the structure of the insulating plate 6961 on the left is the same as that of the insulating plate 6961 on the right and they are symmetrically distributed on the left and right.

[0039] According to the above scheme: the insulating plate 6961 is fixedly connected to the right end of the connecting plate 691, and a clamping groove 6962 is opened at the right end. The anti-skid twill layer 6963 is fixedly connected in the clamping groove 6962. When the device fixes the cable, the insulating plate 6961, under the coordinated action of relevant components, wraps the cable through the clamping groove 6962, and uses the anti-skid twill layer 6963 to increase the friction with the cable surface. At the same time, due to its inner arc structure and symmetrical distribution on the left and right, it can fit the circular appearance of the cable well, so that the clamping force is evenly distributed on the circumference of the cable, thereby firmly fixing the cable and insulating it. The edge plate 6961 itself acts as an insulator to avoid safety hazards such as cable leakage. The anti-slip twill layer 6963 significantly enhances the clamping friction of the cable, ensuring that the cable will not easily slip off under tension, ensuring the firmness of the cable fixation, and maintaining stable power transmission. The arc structure and symmetrical distribution ensure that the cable is evenly stressed, preventing cable damage due to excessive local stress and extending the service life of the cable. The insulation performance effectively eliminates the safety risks caused by cable leakage and improves the safety of the entire overhead transmission line system during use. It is especially suitable for environments such as high-voltage overhead power transmission.

When the tension needs to be adjusted, the iron rope sleeve 2 is pulled backward, and under the action of force Under the action of the tension device 6, the left plate 651 and the right plate 63 will be pulled forward relative to each other. Since the movable component 65 and the right plate 63 are fixedly connected with the buffer component 69, the buffer component 69 includes components such as a connecting plate 691.
