Technical Field

[0001] The utility model belongs to the technical field of power line clamps, and in particular relates to a power engineering line clamp. Background Art

[0002] Wire clamps in power engineering are important components used to connect wires or cables to form electrical connections. They are usually used to fix, connect and protect power lines to ensure the reliability and safety of power transmission. Wire clamps ensure the firmness and conductivity of electrical connections by clamping wires or cables.

[0003] During the power transmission process, the tension and extrusion forces borne by the wire clamp will cause deformation of the wire clamp material, especially under harsh environmental conditions, such as high temperature, humidity or frequent mechanical vibration. The metal material of the wire clamp is prone to plastic deformation, resulting in deformation and bending of the clamping part. This deformation may reduce the connection reliability of the wire clamp and even affect the stability and safety of power transmission. In addition, traditional wire clamps are usually locked and fixed with multiple bolts, but this method adds cumbersome installation and disassembly steps, resulting in low work efficiency.

When the sliding block 2 drives the two clamping blocks 21 to slide out from the bottom of the protective support cover 1, the two clamping blocks 21 are driven by the torsion spring to expand to both sides, so that the two clamping blocks 21 are A gap is created between the clamping blocks 21, which is convenient for disassembling and installing wires and cables. When the wires and cables are placed between the two sliding blocks 2, by pushing the two clamping blocks 21 to slide upward, the two clamping blocks 21 push the sliding block 2 to slide deeper into the protective support cover 1, and the clamping blocks 21 are affected by the bottom opening of the protective support cover 1 and begin to merge and close, so that the two sliding blocks 2 can clamp and fix the wires and cables through the arc groove 211 and the arc clamping plate 22. When the clamping block 21 completely enters the protective support cover 1, the sliding block 2 drives the two clamping blocks 3 to reach the two limit The two engaging blocks 3 slide into the corresponding limiting slots 12, so that the protective support cover 1 can limit the two engaging blocks 3 through the two limiting slots 12, and the two engaging blocks 3 drive the sliding block 2 and the components thereon to be limited inside the protective support cover 1, so that the side of the clamping block 21 can be completely wrapped by the protective support cover 1. At this time, the protective support cover 1 can support the clamping block 21 from the rear when clamping and supporting the wires and cables, thereby improving the stability of the clamping block 21 when in use. When the pulling factor produces deformation, the protective support cover 1 can perform secondary limit on the clamping block 21, thereby improving the deformation resistance of the clamping block 21, thereby improving the reliability of the support and fixation of the wires and cables, and then improving the stability and safety of power transmission. When installing the wires and cables, it is only necessary to control the sliding block 2 to drive the clamping block 21 to move downward and unfold, and then place the wires or cables in the snap-in position between the two clamping blocks 21, and push the clamping block 21 upward to complete the locking. There is no need for cumbersome multiple bolt connections, which reduces the installation and disassembly steps, thereby improving work efficiency.

The arc-shaped clamping plate 22 uses the first spring 221 to realize elastic clamping of telecommunications or cables, thereby reducing the possibility that the outer skin of the cable or the cable is easily damaged by the extrusion stress under hard clamping.

[0021] The arc-shaped inner walls of the two arc-shaped clamping plates 22 are fixedly connected with anti-skid pads 223, and the corresponding ends of the two anti-skid pads 223 are in contact; the arc-shaped clamping plates 22 are in contact with the wires and cables through the anti-skid pads 223, increasing the friction resistance between the wires and cables, thereby improving the limiting effect on the wires or cables.

A traction rope 32 is fixedly connected between the two locking blocks 3, and the second spring 31 and the traction rope 32 exert force on the locking block 3 in opposite directions; the second spring 31 pushes the locking block 3, and when the locking block 3 is limited by the inner wall of the protective support cover 1, the locking block 3 squeezes the second spring 31, and when the clamping block 21 pushes the sliding block 2 to lift upward, the sliding block 2 drives the two locking blocks 3 to reach the position of the limiting slot 12, so that the locking block 3 can automatically complete the locking with the limiting slot 12 under the push of the second spring 31, and the traction rope 32 connects the two locking blocks 3, and by controlling the traction rope 32, the two locking blocks 3 can be pulled at the same time, so that the two locking blocks 3 can synchronously complete the disengagement action from the corresponding limiting slot 12.

Touch pressure sensors 42 corresponding to the side panels 4 are installed on both sides of the protective support cover 1, and the extrusion plates 41 are in contact with one end of the corresponding touch pressure sensors 42; the protective support cover 1 supports the two side panels 4, and the torsion springs drive the side panels 4 to fit against the side walls of the protective support cover 1. When the clamping block 21 squeezes the protective support cover 1 to cause the lower side wall of the protective support cover 1 to bend and deform, the protective support cover 1 can squeeze and push the side panels 4, thereby enabling the side panels 4 to drive the extrusion plates 41 to approach the protective support cover 1, and the extrusion plates 41 squeeze the touch pressure sensors 42, so that the touch pressure sensors 42 can trigger induction to send out an alarm to the power department, so as to carry out timely maintenance and replacement, and avoid continuous deformation affecting the limiting effect of wires and cables.

[0025] The working principle and use process of the utility model are as follows: when installing the wires or cables, the wires or cables are placed between the two clamping blocks 21, and then the clamping blocks 21 are pushed to slide upwards, and the two clamping blocks 21 push the sliding block 2 to slide deeper into the protective support cover 1. The clamping blocks 21 are affected by the bottom opening of the protective support cover 1 and begin to merge and close together, so that the two sliding blocks 2 can clamp and fix the wires and cables through the arc groove 211 and the arc clamping plate 22. When the clamping blocks 21 completely enter the protective support cover 1, the sliding block 2 drives the two clamping blocks 3 to reach the positions of the two limit slots 12, and the two second springs 31 respectively push the corresponding clamping blocks 3 to slide into the limit slots 12, so that the protective support cover 1 can limit the two clamping blocks 3 through the two limit slots 12, and the two clamping blocks 3 drive the sliding block 2 and the components thereon to be limited inside the protective support cover 1, completing the installation, and the sides of the clamping blocks 21 can be affected by the protective support cover 1 Completely wrapped, at this time, the protective support cover 1 can provide secondary support to the rear of the clamping block 21 when clamping and supporting the wires and cables, ensuring the stability of the clamping block 21 during use. When the clamping block 21 is deformed by environmental factors and wire pulling factors after long-term use, the protective support cover 1 can perform secondary positioning of the clamping block 21 to improve the deformation resistance of the clamping block 21, thereby improving the reliability of supporting and fixing the wires and cables, and further improving the stability and safety of power transmission. When the clamping block 21 squeezes the protective support cover 1 to cause the side wall below the protective support cover 1 to bend and deform, the protective support cover 1 can form an extrusion push on the side panel 4, so that the side panel 4 can drive the extrusion plate 41 to approach the protective support cover 1, and the extrusion plate 41 squeezes the touch pressure sensor 42, so that the touch pressure sensor 42 can trigger the induction to send an alarm to the power department, so as to carry out timely maintenance and replacement, and avoid continuous deformation affecting the limiting effect of the wires and cables.
