Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a tension clamp with an anti-slip structure. Background Technology

[0002] In modern society, electricity is an indispensable form of energy for the normal operation of various fields. The power system transmits electrical energy from power plants to various users through a wide range of transmission lines. Transmission lines need to operate stably under different geographical environments and climatic conditions to ensure the continuity of power supply. Tension clamps are important electrical fittings used to fix conductors to withstand conductor tension. They play a key role at the connection between the tower and the conductor in the transmission line, and can transfer the conductor tension to the tower and other supporting structures to ensure the stability of the line under normal operation and external forces.

[0003] Traditional tension clamps may slip out. For example, when the conductor is subjected to a large wind load or the line gallops, the connection between the conductor and the tension clamp may loosen. This is because the clamping structure of traditional clamps may gradually lose its effective clamping force on the conductor under long-term dynamic load. Slippage of the tension clamp will lead to uneven tension distribution on the conductor, which may cause line faults. Excessive local tension may cause the conductor to break strands or even break, affecting the normal operation of power transmission. Moreover, once the tension clamp slips out, it may also trigger a chain reaction, such as uneven stress on adjacent towers, which may threaten the structural stability of the entire transmission line. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tension clamp with an anti-slip structure.

[0005] This utility model is achieved using the following technical solution: a tension clamp with an anti-slip structure, comprising a clamp body, an expansion plate fixedly connected to both sides of the outer surface of the clamp body, a guide groove formed on the surface of the expansion plate, a mounting plate one slidably connected inside the guide groove, a mounting plate two slidably connected inside the guide groove, an assembly base fixedly connected to the upper surface of the mounting plate one, a main sleeve fixedly connected to the surface of the assembly base, a spring one fixedly connected to the inner wall of the main sleeve, a secondary sleeve fixedly connected to the surface of the spring one, grooves formed on both sides of the secondary sleeve, a spring two fixedly connected to the inner wall of the grooves, a reset pin fixedly connected to the surface of the spring two, a positioning seat fixedly connected to the upper surface of the mounting plate two, a locking groove formed inside the positioning seat, and friction blocks fixedly connected to the surfaces of both the mounting plate one and the mounting plate two.

[0006] The above technical solution can effectively prevent the conductor from slipping out of the tension clamp. Through a multi-step fixing method, the conductor is first initially clamped by the friction block, and then the position of the friction block is fixed by the snap-fit ​​structure, which improves the reliability of the conductor fixing. The guide grooves are respectively opened on the surface of the two expansion plates. One expansion plate is slidably connected to the surface of the first mounting plate, and the other expansion plate is slidably connected to the surface of the second mounting plate.

[0007] As a further improvement to the above solution, the secondary sleeve is inserted into the interior of the positioning seat.

[0008] As a further improvement to the above solution, the reset spring pin is adapted to the locking groove.

[0009] The above technical solutions improve the accuracy and stability of the snap-fit ​​structure, ensuring that the reset spring pin can accurately snap into the locking groove under various working environments, avoiding the failure of the anti-slip function due to structural mismatch, and enhancing the reliability of the tension clamp.

[0010] As a further improvement to the above solution, both mounting plate one and mounting plate two are fixedly connected to sliders, which are slidably connected to the inside of the guide groove.

[0011] The above technical solution improves the movement accuracy of mounting plate one and mounting plate two, enabling the friction block to better clamp the wire, reducing the situation where the wire clamping is not firm due to the unstable movement of the mounting plate, and helping to improve the anti-slip performance of the tension clamp.

[0012] As a further improvement to the above solution, the friction block is made of rubber.

[0013] Through the above technical solution, the rubber friction block can provide greater friction, effectively enhancing the clamping force on the conductor and further improving the anti-slip capability of the tension clamp. At the same time, the rubber material is relatively soft and will not damage the surface of the conductor.

[0014] As a further improvement to the above solution, two friction blocks are provided, located on both sides of the clamp body respectively.

[0015] The above technical solution improves the stability of wire fixation by using a double-sided clamping structure.

[0016] This invention pushes mounting plate one and mounting plate two along the guide groove, causing the friction blocks on both sides to move closer together, clamping the wire passing through the clamp body on both sides, so that the wire is subjected to uniform clamping force in the horizontal direction, thus providing an initial fixing effect for the wire. Then, by stretching the secondary sleeve to disengage it from the main sleeve and stretching spring one, the secondary sleeve is inserted into the positioning seat, and the reset pin is pressed to compress spring two before being inserted into the locking groove, thus fixing the positions of mounting plate one and mounting plate two, and thus fixing the positions of the two friction blocks. This effectively prevents the wire from slipping out of the clamp, avoiding potential safety hazards caused by wire slippage. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Please combine Figures 1-4This embodiment of a tension clamp with an anti-slip structure includes a clamp body 1. Expansion plates 2 are fixedly connected to both sides of the outer surface of the clamp body 1. Guide grooves 3 are formed on the surface of the expansion plates 2. Mounting plate 4 is slidably connected inside the guide grooves 3. Mounting plate 5 is slidably connected inside the guide grooves 3. An assembly base 6 is fixedly connected to the upper surface of mounting plate 4. A main sleeve 7 is fixedly connected to the surface of the assembly base 6. A spring 8 is fixedly connected to the inner wall of the main sleeve 7. A secondary sleeve 9 is fixedly connected to the surface of spring 8. Grooves are formed on both sides of the secondary sleeve 9. A spring 10 is fixedly connected to the inner wall of the grooves. A reset pin 11 is fixedly connected to the surface of spring 10. A positioning seat 12 is fixedly connected to the upper surface of mounting plate 5. A locking groove 13 is formed inside the positioning seat 12. Friction blocks are fixedly connected to the surfaces of mounting plate 4 and mounting plate 5. 14. First, the wire is initially fixed using the clamp body 1. Then, the mounting plate 4 and mounting plate 5 are pushed, and they slide along the guide groove 3 and move closer to each other. During this process, the friction blocks 14 on the surfaces of the mounting plate 4 and mounting plate 5 also move closer to each other, thereby clamping the wire passing through the clamp body 1. Next, the secondary sleeve 9 is stretched to disengage from the main sleeve 7 and the spring 8 is stretched. When the secondary sleeve 9 is inserted into the positioning seat 12, the reset spring pin 11 is pressed to compress the spring 10 and retract into the groove. When the secondary sleeve 9 is fully inserted into the positioning seat 12, the reset spring pin 11 coincides with the locking groove 13. The spring 10 resets and drives the reset spring pin 11 to insert into the locking groove 13 to form a snap-fit ​​structure, fixing the position of the mounting plate 4 and mounting plate 5, and then fixing the position of the friction block 14, thereby achieving further positioning and fixing of the wire and preventing loosening and detachment.

[0025] The secondary sleeve 9 is inserted into the interior of the positioning seat 12.

[0026] The reset spring pin 11 is adapted to the locking groove 13. When the secondary sleeve 9 is inserted into the positioning seat 12 to the appropriate position, the reset spring pin 11 can be accurately inserted into the locking groove 13 because it is adapted to the locking groove 13, thereby fixing the position of the secondary sleeve 9, and then fixing the positions of the mounting plate 1 4 and the mounting plate 2 5, so as to achieve a stable clamping of the wire.

[0027] Both mounting plate 4 and mounting plate 5 have sliders fixedly connected to their surfaces. These sliders are slidably connected to the inside of the guide groove 3. This allows mounting plates 4 and 5 to slide smoothly along a predetermined direction. When mounting plates 4 and 5 are pushed closer or further apart, the cooperation between the sliders and the guide groove 3 ensures the accuracy and straightness of their movement, thereby ensuring that the friction block 14 can accurately clamp the wire.

[0028] The friction block 14 is made of rubber. When the mounting plate 1 4 and the mounting plate 2 5 approach each other, the rubber friction block 14 clamps the wire and uses the friction between the rubber and the surface of the wire to fix the wire and prevent the wire from slipping during normal operation.

[0029] There are two friction blocks 14, located on both sides of the clamp body 1. The double-sided clamping method can apply pressure to the wire from two directions, so that the wire is subjected to uniform clamping force in the horizontal direction, thereby fixing the wire more firmly.

[0030] The implementation principle of the anti-slip structure tension clamp in this embodiment is as follows: The operator first uses the clamp body 1 to initially fix the wire. Then, the operator pushes the mounting plate 4 and mounting plate 5 in the guide grooves 3 on both sides of the clamp body 1. Since both mounting plate 4 and mounting plate 5 have fixed sliders, the sliders slide in the guide grooves 3, allowing mounting plate 4 and mounting plate 5 to smoothly approach each other in a predetermined direction. During this process, the friction blocks 14 fixedly connected to the upper surfaces of mounting plate 4 and mounting plate 5 also approach each other, initially clamping the wire passing through the clamp body 1 from both sides. Because the rubber friction blocks 14 have a large frictional force with the wire surface, they can prevent the wire from slipping during the initial operation. The operator then pulls the secondary sleeve 9 connected by spring 8 inside the main sleeve 7, causing the secondary sleeve 9 to detach from the main sleeve. The tube 7 is stretched by the spring 8, and then the secondary sleeve 9 is inserted into the positioning seat 12 fixed on the upper surface of the mounting plate 2 5. Before inserting the secondary sleeve 9 into the positioning seat 12, the operator presses the reset spring pin 11 connected by the spring 2 10 in the grooves on both sides of the secondary sleeve 9, so that the reset spring pin 11 compresses the spring 2 10 and retracts into the groove. When the secondary sleeve 9 is fully inserted into the positioning seat 12, since the reset spring pin 11 is adapted to the locking groove 13 opened inside the positioning seat 12, the reset spring pin 11 and the locking groove 13 coincide. The spring 2 10 resets and drives the reset spring pin 11 to insert into the locking groove 13, forming a snap-fit ​​structure, fixing the position of the mounting plate 1 4 and the mounting plate 2 5, and thus fixing the position of the friction block 14 on the surface of the mounting plate 1 4 and the mounting plate 2 5, so as to further fix the positioning of the wire and prevent the wire from loosening and detaching in subsequent work.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
