Description

Technical Field

[0001] This utility model relates to the field of power fittings for power transmission lines, and in particular to a suspension clamp with balance adjustment. Background Technology

[0002] Suspension clamps, also known as hanging clamps, are common hardware products installed on high-voltage power line towers. They are primarily used for overhead cables to secure them, maintaining their height and protecting the conductors from wear and damage during long-term operation. In the installation of low-voltage power cables and fiber optic cables, various sizes of suspension clamps are generally used to fix the cables in a suspended manner. However, current suspension clamps only serve a fixing function and cannot balance the tension at both ends. Uneven tension at both ends of a high-voltage power line tower can cause the tower to tilt or even collapse, resulting in significant losses. Utility Model Content

[0003] The purpose of this invention is to provide a suspension clamp with balance adjustment. This invention can maintain tension balance at both ends and prevent high-voltage power towers from tilting or even falling down, thus preventing huge losses.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a suspension cable clamp with balance adjustment, comprising a bracket, a hull, and a pressure plate. The hull is connected to the bottom of the bracket and has a positioning groove for positioning the cable. The pressure plate is connected to the hull via two sets of locking components. Adjusting the locking components can cause the pressure plate to press the cable firmly onto the positioning groove of the hull. It also includes a balance adjustment component, comprising a sliding plate, a support plate, and two limiting blocks. The sliding plate is slidably disposed at the bottom of the pressure plate. A sliding hole is provided through the center of the pressure plate, extending laterally. A connecting rod passes through the sliding hole on the pressure plate. The support plate is slidably disposed at the upper part of the pressure plate and is connected to the connecting rod. Multiple ball bearings are slidably disposed at the bottom of the support plate, and these ball bearings roll in cooperation with the upper part of the pressure plate. The two limiting blocks are respectively installed on the left and right sides of the pressure plate corresponding to the support plate, for limiting the travel of the support plate.

[0005] By adopting the above technical solution, when the cable tension on both sides of the suspension clamp is uneven, if the tension on one end is too large, the cable at that end will cause the sliding plate to slide in a small range (overcoming the friction between the cable and the hull and the friction between the sliding plate and the pressure plate). The limiting block limits the support plate, realizing the stroke control of the cable's own sliding. The small range of cable sliding can balance the tension on both sides and prevent the high-voltage power tower from tilting or even falling down, causing huge losses.

[0006] The present invention is further configured such that a screw is provided at the upper end of the connecting rod, and a first nut and a second nut are threadedly connected to the screw. The first nut and the second nut abut against each other. When the first nut is tightened, the first nut restricts the support plate to the upper end of the pressure plate.

[0007] By adopting the above technical solution, tightening the first nut can realize the linkage connection between the support plate and the slide plate, so that the two can slide synchronously. The second nut is set to abut against the first nut to prevent the first nut from loosening and improve the reliability of the structure.

[0008] The present invention is further provided that a washer is sandwiched between the first nut and the support plate.

[0009] By adopting the above technical solution, the contact area is increased by using a gasket, which disperses the stress of the first nut and improves the stability of the support plate connection structure.

[0010] The present invention is further configured such that the upper end of the pressure plate is provided with a guide groove along the horizontal direction, the lower end of the support plate is provided with a limiting sleeve corresponding to the position above the guide groove, the lower half of the ball is rotatably disposed on the guide groove, and the upper half of the ball is rotatably disposed inside the limiting sleeve.

[0011] By adopting the above technical solution, the ball can be stably positioned, allowing it to roll within the limiting sleeve on the support plate and along a specific path (guide groove), thus improving the stability of the support plate's sliding process.

[0012] The present invention is further configured such that the limiting block is connected to the pressure plate by an adjusting screw, the limiting block has a through hole, the upper end of the pressure plate has a screw hole, the screw of the adjusting screw passes through the through hole and is threaded into the screw hole, and the screw head of the adjusting screw abuts against the upper end of the limiting block.

[0013] By adopting the above technical solution, the position of the limit block is adjustable. The position of the limit block can be adjusted according to the actual design needs, thereby realizing the adjustment of the slide travel and thus the adjustment of the maximum sliding travel of the cable.

[0014] The present invention is further provided that the upper end of the pressure plate is provided with guide ribs corresponding to the positions on both sides of each limiting block, and the guide ribs extend laterally.

[0015] By adopting the above technical solution, guide ribs are set to guide the limiting block, enabling it to slide in a specific direction, making adjustment more convenient and accurate.

[0016] The present invention is further provided that the bottom of the skateboard is evenly provided with a plurality of resistance-increasing ribs.

[0017] By adopting the above technical solution, the friction between the slide plate and the cable can be increased. The slide plate uses the friction-increasing ribs to grip the cable. When the tension at both ends is balanced, the clamping effect on the cable can be improved. When the tension is unbalanced, the cable and the slide plate can slide synchronously.

[0018] The present invention is further configured such that the bracket includes a hanging block connected to the high-voltage power line tower and two hanging plates rotatably connected to the hanging block by screws, and the bottom ends of the two hanging plates are rotatably connected to the hull by screws.

[0019] By adopting the above technical solution, the angle of the bracket can be adjusted. With the deflection angle as the control variable, it can also achieve the effect of adjusting the tension at both ends of the clamp within a small range. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: As attached Figures 1-5The suspended cable clamp shown includes a hanger 1, a hull 2, and a pressure plate 3. The hull 2 ​​is connected to the bottom of the hanger 1 and has a positioning groove 4 for positioning the cable. The pressure plate 3 is connected to the hull 2 ​​by two sets of locking components 5. Adjusting the locking components 5 causes the pressure plate 3 to press the cable into the positioning groove 4 of the hull 2. The locking components 5 consist of a U-shaped rod and a nut. The U-shaped rod passes through the hull 2 ​​and the pressure plate 3. Screwing the nut onto the U-shaped rod causes the pressure plate 3 to press the cable into the hull 2. The clamp also includes a balance adjustment component 6, which includes a sliding plate 7, a support plate 8, and two limiting blocks 9. The sliding plate 7 extends horizontally... A sliding hole 10 is provided in the middle of the pressure plate 3, which extends laterally. A connecting rod 11 is provided on the pressure plate 3, which passes through the sliding hole 10. The width of the connecting rod 11 is similar to the width of the sliding hole 10, but the length of the sliding hole 10 is much greater than the lateral length of the connecting rod 11. A support plate 8 is slidably provided on the upper part of the pressure plate 3, and the support plate 8 is connected to the connecting rod 11. Multiple balls 12 are rolled at the bottom of the support plate 8, and the balls 12 roll in cooperation with the upper part of the pressure plate 3. Two limiting blocks 9 are respectively installed on the left and right sides of the pressure plate 3 corresponding to the support plate 8, which are used to limit the stroke of the support plate 8. When the cable tension on both sides of the suspension clamp is uneven, if the tension on one end is too high, the cable at that end will cause the slide plate 7 to slide within a small range (overcoming the friction between the cable and the hull 2 ​​and the friction between the slide plate 7 and the pressure plate 3). The limit block 9 limits the support plate 8, thereby controlling the travel of the cable itself. The small-range sliding of the cable can balance the tension on both sides and prevent the high-voltage power tower from tilting or even falling down, causing huge losses.

[0028] As attached Figure 2 and attached Figure 3 As shown, the upper end of the connecting rod 11 is provided with a screw 13. The slide plate 7, connecting rod 11, and screw 13 can be an integral structure. A first nut 14 and a second nut 15 are threadedly connected to the screw 13. The first nut 14 and the second nut 15 abut against each other. When the first nut 14 is tightened, it restricts the support plate 8 to the upper end of the pressure plate 3. Tightening the first nut 14 enables the linkage connection between the support plate 8 and the slide plate 7, allowing them to slide synchronously. The second nut 15 abuts against the first nut 14 to prevent the first nut 14 from loosening, thus improving the reliability of the structure.

[0029] As attached Figure 3 As shown, a washer 16 is also sandwiched between the first nut 14 and the support plate 8. The washer 16 increases the contact area, which disperses the stress of the first nut 14 and improves the stability of the connection structure of the support plate 8.

[0030] As attached Figure 2 and attached Figure 3As shown, the upper end of the pressure plate 3 is provided with a guide groove 17 along the horizontal direction. The guide groove 17 can be a concave arc shape. The lower end of the support plate 8 is provided with a limiting sleeve 18 corresponding to the position above the guide groove 17. The limiting sleeve 18 can be welded to the support plate 8 or it can be an integral structure with the support plate 8. The lower half of the ball bearing 12 is rolled on the guide groove 17, and the upper half of the ball bearing 12 is rolled inside the limiting sleeve 18. This design can stably achieve the positioning of the ball bearing 12, making it roll within the limiting sleeve 18 on the support plate 8 and roll along a specific path (guide groove 17), thus improving the stability of the sliding process of the support plate 8.

[0031] As attached Figure 3 As shown, the limiting block 9 is connected to the pressure plate 3 via an adjusting screw 19. The screw head of the adjusting screw 19 has a built-in washer. An elongated hole 20 is provided through the limiting block 9, the length of which is much larger than the diameter of the adjusting screw 19. A screw hole 21 is provided at the upper end of the pressure plate 3. The screw 13 of the adjusting screw 19 passes through the elongated hole 20 and is threaded into the screw hole 21. The screw head of the adjusting screw 19 is pressed against the upper end of the limiting block 9. The position of the limiting block 9 is adjustable, and can be adjusted according to actual design needs to adjust the stroke of the slide plate 7, thereby adjusting the maximum sliding stroke of the cable. Furthermore, the limiting block 9 can be made of silicone material.

[0032] As attached Figure 4 As shown, guide ribs 22 are respectively provided on both sides of each limiting block 9 at the upper end of the pressure plate 3. The guide ribs 22 extend laterally, and the guide ribs 22 are in pairs, forming a guide channel between the two guide ribs 22. The guide ribs 22 guide the limiting block 9, so that it can slide in a specific direction, making the adjustment more convenient and accurate.

[0033] As attached Figure 5 As shown, the bottom of the slide plate 7 is also evenly provided with multiple friction-increasing ribs 23. This design can increase the friction between the slide plate 7 and the cable. The slide plate 7 uses the friction-increasing ribs 23 to grip the cable. When the tension at both ends is balanced, it can improve the clamping effect on the cable. When the tension is unbalanced, it can achieve synchronous sliding of the cable and the slide plate 7.

[0034] As attached Figure 1 As shown, the bracket 1 includes a hanging block 24 connected to the high-voltage power line tower and two hanging plates 25 rotatably connected to the hanging block 24 by screws. The bottom ends of the two hanging plates 25 are rotatably connected to the hull 2 ​​by screws. The angle of the bracket 1 is adjustable, with the deflection angle as the control variable, which can also achieve the effect of adjusting the tension at both ends of the clamp within a small range.
