Description

Technical field:

[0002] As a key component, the tension clamp is mainly used to fix or connect the conductors and bear the tension of the conductors or lightning conductors to ensure the stable operation of the power lines at corners, joints and terminal connections. The power fittings used for the tension clamps are an indispensable key component in the power system. As metal parts used in conjunction with the tension clamps, such as U-bolts, nuts, pressure plates, etc., they jointly undertake the important tasks of fixing, connecting and protecting the conductors. These power fittings are precisely designed and manufactured to ensure that the conductors can be firmly fixed on the tension clamps, effectively bear and disperse the tension from the conductors, thereby ensuring the safe and stable operation of the power lines.

[0003] The tension clamp requires electrical maintenance when the clamp becomes hot, the bolts become loose, the contact surface becomes oxidized and corroded, or the hardware is damaged.

[0004] However, during the power maintenance process, since the maintenance process is usually carried out at high altitudes, when replacing or repairing the tension clamp lock on the tension clamp, sometimes there is a problem that the tension clamp lock leaves the power environment directly after disassembly, and thus falls to the ground, which causes it to be damaged or difficult to find. If the tension clamp lock is in a long-term and vibrating power environment, there is still a possibility of loosening, which affects the safety and stability of the power fittings in the power environment, and there are still hidden dangers in whether the power system can operate reliably.

Specific implementation method:

[0028] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] For example, see Figures 1 to 9The present invention provides a technical solution: an electric power fitting for a tension clamp, comprising a U-shaped rod 1, two threaded components 2 and a mounting component 3, wherein the outer wall of the threaded component 2 is threadedly connected with a tension clamp lock 45, and the inner wall of the tension clamp lock 45 is in a sliding connection relationship with the mounting component 3, and the two ends of the U-shaped rod 1 are respectively fixedly connected with the two threaded components 2, and the bottom end of the threaded component 2 is fixedly connected with the mounting component 3. The above components are regarded as a whole, and the whole is installed on the tension clamp body 4, and an anti-drop component and a safety mechanism are arranged inside the mounting component 3, and the anti-drop component includes an anti-drop block 30, an impact block 8 and a threaded block 6, and the threaded block 6 is formed with the inside of the mounting component 3. Threaded connection relationship, the top of the threaded block 6 is movably connected with a transfer rod 7, and the transfer rod 7 is fixedly connected to the bottom end of the impact block 8. The impact block 8 is movably connected to the anti-fall block 30 and can deflect the anti-fall block 30 under certain circumstances. The safety mechanism includes a trapezoidal block 15, a trapezoidal block 22 and a built-in block 23. A side groove 21 is provided at the bottom end of the mounting component 3. The trapezoidal block 15 is slidably connected to the inside of the side groove 21. The trapezoidal block 15 and the trapezoidal block 22 are in a movably connected relationship. The contact ends of the trapezoidal block 15 and the trapezoidal block 22 are both inclined at 45°. One end of the trapezoidal block 22 is fixedly connected to the built-in block 23, and the built-in block 23 can be displaced into the interior of the mounting component 3. With the help of a tool, the threaded block 6 is screwed, and through the anti-drop assembly and safety mechanism, the impact block 8 will collide with the anti-drop blocks 30 at both ends during the upward movement. When the threaded block 6 is moved to the end of the threaded groove 5, the anti-drop block 30 is flipped to the maximum angle and is located in the outer cavity of the mounting component 3. The disassembled tension clamp lock 45 will not fall directly off from the high altitude, and the stability and safety of the power line are improved. Under normal use scenarios of power fittings, the two L-shaped blocks 37 pass through the transverse groove 36 and limit the bottom end of the tension clamp lock 45, which effectively prevents the tension clamp lock 45 from accidentally loosening due to vibration in the power environment, thereby ensuring the safety and stability of the power connection point again, and providing a solid guarantee for the reliable operation of the power system.

[0030] For example 2, please refer to Figures 1 to 9On the basis of the first embodiment, the interior of the mounting component 3 is hollow, and a threaded groove 5 is provided on the inner wall of the mounting component 3. The built-in block 23 can be moved to the inside of the threaded groove 5 after change. The threaded block 6 is threadedly connected to the inside of the threaded groove 5. A cross groove is provided at the bottom end of the threaded block 6. The impact block 1 8 is located inside the mounting component 3. The outer walls on both sides of the impact block 1 8 are fixedly connected to the limit block 2 34. The cross section of the limit block 2 34 is convex. The interior of the mounting component 3 is provided with two vertical grooves 33 that are far away from each other and symmetrically distributed. The limit block 2 34 is slidably connected to the inside of the vertical groove 33. The interior of the mounting component 3 is provided with two through grooves 28 that are far away from each other and symmetrically distributed. The through groove 28 is in a through shape as a whole. The anti-drop block 30 is rotatably connected between the inner walls on both sides of the through groove 28. The anti-drop block 30 is integrally connected to the The cross-section of the body is fan-shaped, and an arc spring 32 is fixedly connected between one end of the anti-fall block 30 and the bottom end of the inner wall of the through groove 28, and the other end of the anti-fall block 30 is fixedly connected to a limit block 31. Two limit grooves 29 that are far away from each other and symmetrically distributed are provided on the outer wall of the mounting component 3, and the limit block 31 is slidably connected to the inside of the limit groove 29. The rotation point of the anti-fall block 30 is at a point close to the center of the circle, and the overall deflection process of the anti-fall block 30 will not contact the inside of the through groove 28. Both ends of the impact block 8 are set at an inclination of 45°, and a plurality of circular grooves 9 are provided inside the impact block 8. The inner cavity of the circular groove 9 is rotatably connected to a roller block, and the radius of the roller block is smaller than the radius of the circular groove 9. The outer wall of the circular groove 9 is fixedly connected to a plurality of rubber pads 10 that are equidistant and rotationally symmetrically distributed about the axis of the roller block.

[0031] By setting the limit block 2 34 and the vertical groove 33, the impact block 18 is connected with the inner wall of the installation component 3, which indirectly increases the contact area between the impact block 18 and the inner wall of the installation component 3, and at the same time limits the displacement process of the impact block 18, which can only stably move in the vertical direction. After being screwed by the tool, the thread block 6 will gradually move toward the inside of the thread groove 5, and the transmission rod 7 will be pushed by the thread block 6 to synchronously drive the impact block 18 to move upward, and the distance between the impact block 18 and the anti-drop block 30 will gradually shorten. After that, each rubber pad 10 will contact the inclined end of the anti-drop block 30, and each roller block will rotate. The rubber pad 10 climbs upward along the inclined end of the anti-drop block 30, and the anti-drop block 30 rotates accordingly, and the arc spring 32 After being stretched, the limit block 31 flips over and detaches from the limit groove 29, and then one end of the anti-fall block 30 slides along the side of the impact block 8, but the anti-fall block 30 will not produce an angle change afterwards. The two anti-fall blocks 30 exceed the inside of the through groove 28 and come to the outside. The disassembled tension clamp lock 45 will not fall directly to the ground, but will be received by the anti-fall block 30, which is beneficial to improving the maintenance efficiency. The roller block rotation replaces the direct friction contact mode, so that the anti-fall block 30 can flip more smoothly. The additional depth optimization configuration of each rubber pad 10 increases the friction force and is beneficial to the transmission of force. In short, the anti-fall block 30 can flip smoothly and stably through the set roller block and rubber pad 10.

[0032] For example 3, please refer to Figures 1 to 9 On the basis of the second embodiment, the outer walls of both sides of the trapezoidal block 15 are fixedly connected with protrusions 16, the inner walls of both sides of the side groove 21 are provided with rectangular grooves 17 and inner grooves 24, the protrusions 16 are slidably connected inside the rectangular grooves 17, the inner grooves 24 are slidably connected with connecting plates 25, the trapezoidal block 22 is fixedly connected between the two connecting plates 25, one end of the inner wall of the inner groove 24 is fixedly connected with an elastic member 26 and two elastic members 27, the elastic member 26 is located in the middle of the two elastic members 27, the elastic member 26 is flat and long as a whole, and its cross section is O-shaped, and the elastic member 27 is overall horizontally The cross-section is circular, and the built-in block 23 is a part of the threaded groove 5, but it can be displaced together with the trapezoidal block 22. The top of the trapezoidal block 15 is fixedly connected with two wave blocks 18 that are symmetrically distributed and far away from each other. There are multiple protrusions at both ends of the wave block 18 and are wavy. The top of the side groove 21 is provided with two fastening grooves 19 that are symmetrically distributed and far away from each other. The inner walls on both sides of the fastening groove 19 are fixedly connected with multiple elastic rubber parts 20 arranged at equal distances. The elastic rubber part 20 is elastic as a whole and a rough layer is adhered to its outer surface. The height of the side groove 21 is greater than the height of the trapezoidal block 15.

[0033] When the thread block 6 rotates to the end of the thread groove 5, that is, it is adjusted to a state where it cannot rotate anymore, the pressure trapezoidal block 15 is required. Since the contact ends of the trapezoidal block 15 and the trapezoidal block 22 are both inclined at 45 degrees, the displacement of the trapezoidal block 15 will synchronously push the trapezoidal block 22. The trapezoidal block 22 and the built-in block 23 are displaced together and enter the inner cavity of the thread groove 5. At this time, the top of the built-in block 23 just slides in contact with the bottom end of the thread block 6 to limit it, preventing the thread block 6 from gradually rotating in the opposite direction after being affected by vibration for a long time, thereby ensuring the supporting and limiting effect of the anti-drop block 30. When the trapezoidal block 22 is displaced, the two connections The plate 25 is displaced synchronously and first squeezes the elastic piece 1 26 and then squeezes the two elastic pieces 27. The elastic piece 1 26 and the two elastic pieces 27 are provided to automatically pull the built-in block 23 back to its original position during subsequent operations. During the above process, the trapezoidal block 15 will push the wave block 18 into the fastening groove 19, and each elastic rubber piece 20 will be stuck in the gap of the wave protrusion of the wave block 18. Due to the provision of the rough layer, the friction between the wave-shaped protrusion of the wave block 18 and each elastic rubber piece 20 is increased, reducing the possibility of its detachment due to long-term shaking, making the limiting effect of the built-in block 23 more stable.

[0034] Example 4, please refer to Figures 1 to 9 On the basis of the third embodiment, a cylindrical groove 35 is provided inside the threaded component 2, a through transverse groove 36 is provided on the outer wall of the threaded component 2, an L-shaped block 37 is slidably connected to the inner walls of the two transverse grooves 36, a circular groove 38 is provided at one end of the two L-shaped blocks 37 close to each other, a straight spring 1 39 is fixedly connected between the inner walls of the two circular grooves 38, the lower end of the L-shaped block 37 is inclined at 45 degrees, a plurality of equidistantly arranged elliptical grooves 42 are provided on the inner wall of the cylindrical groove 35, a straight spring 2 43 is fixedly connected to the bottom end of the inner wall of each elliptical groove 42, an impact block 2 40 is provided inside the cylindrical groove 35, two sliding rods 41 are penetrated and fixedly connected to the interior of the impact block 2 40, and the two ends of the sliding rod 41 are fixedly connected to the two ends of the sliding rod 41. The ends are fixedly connected to the tops of two straight springs 43 respectively, and the two ends of the impact block 40 are also inclined at 45°. The bottom end of the impact block 40 is fixedly connected to two vertical rods 44 that are far away from each other and symmetrically distributed. The top of the impact block 8 is fixedly connected to a vertical rod 11. The outer walls of both sides of the vertical rod 11 and the side where the two vertical rods 44 are close to each other are provided with concave vertical through grooves, and the interior of each vertical through groove is fixedly connected to a tooth plate 12. Two rotating shafts 13 that are far away from each other and symmetrically distributed are rotatably connected to the inner wall of the cylindrical groove 35. Hollow column gears 14 are fixedly connected to the outer walls of the two rotating shafts 13, and the hollow column gears 14 are in a meshing relationship with two adjacent tooth plates 12.

[0035] In the initial state, as shown in the instruction manual Fig. 9As shown, a part of the two L-shaped blocks 37 extends out of the transverse groove 36. It can be seen from the accompanying drawings in the specification that the L-shaped block 37 is located just below the clamp lock 45 to prevent it from being loosened due to long-term vibration and ensure safety. The vertical rod 11 moves upward synchronously with the impact block 8. Through the various tooth plates 12, rotating shafts 13 and hollow column gears 14, the upward movement of the vertical rod 11 results in the rotation of the hollow column gear 14, which makes the vertical rod 11 move upward. Rod 2 44 moves downward, and the two vertical rods 2 44 drive the impact block 2 40 to move downward together. The inclined end of the impact block 2 40 slides along the inclined end of the L-shaped block 37 again, and the two sliding rods 41 press down each straight spring 2 43 respectively. The distance between the two L-shaped blocks 37 is gradually shortened, and the external force on the straight spring 1 39 is increasingly reduced, and it will rebound. The L-shaped block 37 is completely displaced into the inside of the transverse groove 36. At this point, there is no obstruction on the outer wall of the threaded component 2, which is conducive to the removal of the clamping lock 45.

[0036] In actual use, through the tooth plates 12, rotating shafts 13 and hollow column gears 14, the upward movement of the vertical rod 11 results in the rotation of the hollow column gear 14, and the vertical rod 2 44 moves downward, and the two vertical rods 2 44 drive the impact block 2 40 to move downward together, and the inclined end of the impact block 2 40 slides along the inclined end of the L-shaped block 37 again, and the two sliding rods 41 press down each straight spring 2 43 respectively, and the distance between the two L-shaped blocks 37 gradually shortens, and the external force on the straight spring 1 39 is increasingly reduced, and it will rebound, and the L-shaped block 37 is completely displaced into the transverse groove 36. At this point, there is no obstruction on the outer wall of the threaded component 2, and the clamping lock 45 can be rotated and moved downward. The upward movement process of the vertical rod 11 is traced back to when the thread block 6 is screwed by a tool, it will gradually move toward the thread groove 5. Internal displacement, the transmission rod 7 is pushed by the threaded block 6 to synchronously drive the impact block 8 to move upward, and the distance between the impact block 8 and the anti-fall block 30 is gradually shortened, and then each rubber pad 10 will contact the inclined end of the anti-fall block 30, and each roller block will rotate. The rubber pad 10 climbs upward along the inclined end of the anti-fall block 30, and the anti-fall block 30 rotates accordingly, and the arc spring 32 is stretched, and the limit block 31 flips over and detaches from the inside of the limit groove 29, and then one end of the anti-fall block 30 will slide along the side of the impact block 8, but the anti-fall block 30 will not produce an angle change afterwards. The two anti-fall blocks 30 exceed the inside of the through groove 28 and come to the outside. The disassembled tension clamp lock 45 will not fall directly to the ground, but will be received by the anti-fall block 30, and the stability and safety of the power line are improved.
