Description

Technical Field

[0001] The utility model relates to the technical field of power pole towers, and more specifically, to a wire clamp for a power pole tower. Background Art

[0002] Power poles and towers are used to support transmission lines in overhead transmission lines. Power poles and towers are mostly made of steel or reinforced concrete and are the main supporting structures of overhead transmission lines.

[0003] When operators are erecting power poles, they usually use steel strands to fix them, where one end of the steel strand is usually fixed to the ground and the other end is fixed to the power pole. In this process, operators often use wire clamps to achieve force balance on the power pole by stretching the steel strands, thereby ensuring the safe operation of the power line. Existing wire clamps are often fixedly connected to the steel strands by bolts. Although this connection method can achieve a good fixing effect, it requires operators to manually tighten multiple bolts. When too many wire clamps need to be installed, it will cause a lot of repetitive work for operators, reduce the work efficiency of operators, and bring inconvenience to operators' operations. Therefore, it needs to be improved. Utility Model Content

[0032] like Figures 1 to 6 As shown, the utility model provides a wire clamp for a power pole tower, comprising:

[0033] The arc-shaped plate 1 has limit grooves 2 on both sides of the top of the arc-shaped plate 1, and first teeth 3 are fixedly installed on both sides of the inside of the arc-shaped plate 1;

[0034] A pushing mechanism, which is arranged on the front side of the arc-shaped plate 1;

[0035] A clamping mechanism, which is arranged inside the arc-shaped plate 1;

[0036] Among them, the clamping mechanism includes a moving plate 4, the number of which is two, the outer surfaces of the two moving plates 4 are both movably connected to the inside of the arc plate 1, the second teeth 5 are fixedly installed on the opposite sides of the two moving plates 4, and the tops of the two moving plates 4 are fixedly installed with moving blocks 6, the tops of the moving blocks 6 extend to the top of the top of the arc plate 1 through the limiting groove 2, the outer surfaces of the moving blocks 6 are movably connected to the inside of the limiting groove 2, and an extrusion block 7 is movably connected between the two moving plates 4, and the outer surfaces of the top and bottom ends of the extrusion block 7 are both movably connected to the inside of the arc plate 1.

[0037] Due to the design of the shape of the extrusion block 7, when the extrusion block 7 moves backward, it will squeeze and push the two moving plates 4. Due to the limiting effect of the two limiting grooves 2 on the two movable blocks 6, the two moving plates 4 will drive the two movable blocks 6 and the two second teeth 5 to move away from each other.

[0038] The driving agencies include:

[0039] A first fixed block 8, the back of which is fixedly connected to the front of the arc-shaped plate 1, and the interior of the first fixed block 8 is movably connected to the outer surface of the extrusion block 7;

[0041] Since the outer surface of the threaded rod 9 is sleeved with the internal thread of the first fixed block 8, the threaded rod 9 will move backward when it rotates. At the same time, the round shaft 23 will rotate and move backward driven by the threaded rod 9, and then the extrusion block 7 will move backward driven by the round shaft 23.

[0042] Among them, arc blocks 11 are fixedly installed on the left and right sides of the top of the arc plate 1. There are two arc blocks 11. Round rods 12 are fixedly installed on the facing sides of the two arc blocks 11. The outer surface of the other end of the round rod 12 is movably connected to the inner part of the movable block 6.

[0045] When the two movable blocks 6 move toward each other, the two springs 13 will be in a compressed state. Due to the elastic force of the two springs 13, a good restoring effect will be provided for the overall movement of the two movable blocks 6.

[0046] The bottom end of the arc-shaped plate 1 is fixedly mounted with an inclined block 14 , and the interior of the inclined block 14 is movably sleeved with a square rod 15 .

[0047] Due to the design of the square rod 15, the inclined block 14 as a whole can move forward and backward along its outer surface.

[0048] A lead screw 16 is fixedly mounted on the back of the square rod 15 , a round block 17 is threadedly sleeved on the outer surface of the lead screw 16 , and the front side of the round block 17 is movably connected to the back side of the square rod 15 .

[0049] Since the outer surface of the lead screw 16 is sleeved with the inner thread of the round block 17, the round block 17 will move backward along its outer surface when it rotates.

[0050] A handle 18 is fixedly mounted on the outer surface of the round block 17 , and a movable plate 19 is movably sleeved inside the front of the outer surface of the round block 17 .

[0051] Since the interior of the movable plate 19 is movably connected to the interior in front of the outer surface of the round block 17 , when the round block 17 moves backward, the movable plate 19 will move backward driven by the round block 17 .

[0052] A pull rod 20 is fixedly mounted on the front of the movable plate 19 , and the front of the pull rod 20 is fixedly connected to the back of the curved plate 1 .

[0053] When the movable plate 19 moves backward, the movable plate 19 will drive the entire arc plate 1 to move backward through the pull rod 20 .

[0054] A second fixing block 21 is fixedly mounted on the back of the lead screw 16 , and a nut 22 is sleeved on the internal thread of the second fixing block 21 .

[0055] Due to the design of the second fixing block 21 and the nut 22, the entire lead screw 16 can be conveniently fixed on the ground.

[0056] The first teeth 3 and the second teeth 5 are both in a pointed cone shape, and the first teeth 3 and the second teeth 5 are both made of metal.

[0057] Due to the appearance design of the two first teeth 3 and the two second teeth 5, the steel strands can be well clamped and fixed.

[0058] The working principle and use process of this utility model:

[0059] First, the operator places the steel strand inside the arc plate 1. At this time, the outer surfaces of the two moving plates 4 will fit with the outer surfaces of the steel strand. At this time, the operator drives the threaded rod 9 to rotate through the square block 10. Since the inner part of the front side of the first fixed block 8 is threadedly sleeved with the outer surface of the threaded rod 9, the threaded rod 9 will move backward while rotating. At the same time, the round shaft 23 will rotate and move backward while driven by the threaded rod 9. Since the outer surface of the round shaft 23 is movably sleeved with the inner part of the extrusion block 7, the extrusion block 7 will move backward under the drive of the round shaft 23. Due to the design of the shape of the extrusion block 7, when the extrusion block 7 moves backward, it will squeeze and push the two moving plates 4 at the same time, so that the two The moving plate 4 moves, and the two movable blocks 6 will move driven by the two moving plates 4. Due to the design inside the two limit grooves 2, the movement of the two movable blocks 6 will be limited so that they can only move left and right. At this time, the two moving plates 4 will drive the two movable blocks 6 to move away from each other under the limitation of the two limit grooves 2. During this process, the two springs 13 will be in a compressed state. At the same time, the two moving plates 4 will drive the two second teeth 5 to move away from each other. Due to the appearance design of the two first teeth 3 and the two second teeth 5, the two second teeth 5 will cooperate with the two first teeth 3 in the opposite movement to clamp and fix the steel strands, thereby realizing the function of quickly clamping and fixing the steel strands.

[0060] Then the operator uses the four handles 18 to rotate the round block 17 along the outer surface of the lead screw 16. Since the inside of the round block 17 is threadedly sleeved with the outer surface of the lead screw 16, the round block 17 will move backward along the outer surface of the lead screw 16 while rotating. Since the inside of the movable plate 19 is movably sleeved with the outer surface of the round block 17, the movable plate 19 will move backward driven by the round block 17, and then the movable plate 19 will drive the pull rod 20 to move backward, and then the pull rod 20 will drive the inclined block 14 to move backward along the outer surface of the square rod 15 through the arc plate 1, thereby realizing the function of quickly and conveniently adjusting the tightness between the steel strand and the power pole tower.
