Description

Technical Field

[0001] The invention relates to the technical field of cable clamps, in particular to a tension tower wedge-type cable clamp structure. Background Art

[0002] The wedge-type cable clamp is a power cable wiring accessory, which is mainly used for fixing and supporting wires and cables, and enhancing their tensile strength. The Chinese utility model patent with the prior art publication number CN211958710U proposes a split wedge-shaped tension clamp, which includes a clamp body, a wedge-shaped through hole for accommodating a wedge core, a wire groove on the side wall of the wedge core, and side panels detachably fixed to the clamp body on both sides. The head end of the side panel is provided with a fastener fixedly connected to an external connection structure; during the construction process, the construction personnel need to first route the steel strand along the wedge core wire groove and fix the end of the steel strand; then fix the side panel, and finally use the fastener to fix the side panel to the external connection structure, and the installation of the entire clamp is completed.

[0003] When the above-mentioned wedge-shaped tension clamp is in use, the steel strands and cables are routed along both sides of the wire groove of the wedge core, and the splitting force of the wedge core is used to clamp the cables in the clamping space. Since the end of the cable facing the outside of the tension tower is subjected to a large tensile force, while the end of the cable facing the inside of the tension tower is subjected to a smaller tensile force, the tension of the cable on the wedge core is not balanced. As a result, when the cable is subjected to excessive tension and the wedge core and the wedge-shaped shell move, one side of the wedge core is subjected to the tension of the cable and moves toward the outer end of the wedge-shaped shell, while the other side of the wedge core is subjected to the tension of the cable and moves toward the inner end of the wedge-shaped shell. The wedge core is subjected to frictional tension in opposite directions, resulting in failure of the self-tightening clamping of the cable and reduced reliability. Summary of the invention

A plurality of pattern grooves 13; also includes two upper wire grooves 14, the upper ends of the right wedge core 2 and the upper ends of the left wedge core 4 are both provided with the upper wire grooves 14, the two upper wire grooves 14 are arranged opposite to each other, and the two upper wire grooves 14 are respectively connected with the slot 1 of the right wedge core 2 and the slot 2 of the left wedge core 4; also includes two ear plates 20, two connecting rods 21 and a hanging ring 22, the two ear plates 20 are respectively mounted on the left and right side walls of the upper end of the shell 1, the lower ends of the two connecting rods 21 are respectively rotatably connected with the two ear plates 20, and the upper ends of the two connecting rods 21 are rotatably connected with the lower ends of the hanging rings 22.

[0027] The upper end of the lifting ring 22 is connected to the tension tower through a hardware. The lifting ring 22 is movably connected to the shell 1 through two connecting rods 21 and two ear plates 20, so that the shell 1 can move within a certain range. The end of the cable passes between the slot 1 of the right wedge core 2 and the arc-shaped wire groove 1 of the shell 1, and then passes between the slot 2 of the left wedge core 4 and the arc-shaped wire groove 2 of the shell 1. The two upper wire grooves 14 support and guide the cables between the right wedge core 2 and the left wedge core 4 to reduce cable bending damage. The bidirectional threaded rod 6 is rotated so that The positive and negative threads of the bidirectional threaded rod 6 cooperate with the positive and negative threaded holes of the right screw hole block 3 and the left screw hole block 5 respectively to push the right wedge core 2 toward the lower end of the shell 1, and at the same time push the left wedge core 4 toward the upper end of the shell 1, so that the card slot 1 of the right wedge core 2 clamps the outer end of the cable on the arc-shaped wire groove 1 of the shell 1, and at the same time, the card slot 2 of the left wedge core 4 clamps the inner end of the cable on the arc-shaped wire groove 2 of the shell 1.

At the same time, the inner end of the cable rubs against the clamping groove 2 of the left wedge core 4, thereby pulling the left wedge core 4 upward, so that the left wedge core 4 is closer to the arc-shaped wire groove 2 of the shell 1, thereby clamping the inner end of the cable more tightly. When the right wedge core 2 and the left wedge core 4 are subjected to cable tension, the cable is clamped more tightly, thereby increasing the clamping force of the cable, thereby ensuring the self-tightening clamping ability and reliability of the cable. Example 2

[0028] like Figure 4 and Figure 5 As shown, on the basis of Example 1, it also includes two slide grooves 8 and two slide bars 9, the left part of the right wedge core 2 and the right part of the left wedge core 4 are both provided with slide grooves 8, the left part of the right screw hole block 3 and the right part of the left screw hole block 5 are both provided with slide bars 9, the slide bar 9 on the right screw hole block 3 is slidably connected with the slide groove 8 on the left wedge core 4, and the slide bar 9 on the left screw hole block 5 is slidably connected with the slide groove 8 on the right wedge core 2; it also includes four slide grooves 2 10 and four slide bars 2 11, the front and rear end surfaces of the right wedge core 2 and the front and rear end surfaces of the left wedge core 4 are both provided with slide grooves 2 10, the four slide grooves 2 10 are parallel to the bidirectional threaded rod 6, two slide bars 2 11 are provided on the inner wall of the shell 1, and the inner walls of the arc-shaped wire groove 1 and the arc-shaped wire groove 2 of the shell 1 are both provided with slide bars 2 11, and the four slide bars 2 11 are respectively slidably connected with the four slide grooves 2 10.

[0029] The right wedge core 2 and the left wedge core 4 are slidingly connected via two slide grooves 8 and two slide bars 9, so that the right wedge core 2 and the left wedge core 4 are connected as a whole, thereby improving the connection reliability of the right wedge core 2 and the left wedge core 4. The right wedge core 2 and the left wedge core 4 are slidingly connected to the shell 1 via four slide grooves 10 and four slide bars 11, thereby improving the connection reliability of the right wedge core 2 and the left wedge core 4 and the shell 1. Example 3

[0030] like Figure 1 , Figure 2 and Figure 8 As shown, on the basis of Example 1, it also includes a support rod 15, a rotating shaft 16, two cross bars 17 and two wire hoops 18, the upper end of the support rod 15 is connected to the lower end of the shell 1, the rotating shaft 16 is installed at the lower end of the support rod 15, the inner ends of the two cross bars 17 are respectively connected to the rotating shaft 16, and the outer ends of the two cross bars 17 are provided with wire hoops 18, and the two wire hoops 18 are used to clamp the two ends of the cable; it also includes a torsion spring 19, the inner ends of the two cross bars 17 are rotatably connected to the rotating shaft 16, the torsion spring 19 is installed on the rotating shaft 16, and the two ends of the torsion spring 19 are respectively connected to the two cross bars 17.

[0031] The support rod 15 and the rotating shaft 16 support the two cross bars 17. After the cable is clamped and fixed, the two wire clamps 18 clamp the two ends of the cable respectively. The torsion spring 19 elastically supports the two cross bars 17, so that the two wire clamps 18 elastically guide and support the two ends of the cable. When the two ends of the cable swing, the elastic force of the torsion spring 19 buffers the swing of the cable, reduces the bending degree of the cable, and reduces cable damage.

[0032] like Figures 1 to 8As shown, a wedge-type cable clamp structure for a tension tower of the present invention, when working, first the upper end of the lifting ring 22 is connected to the tension tower through the hardware, and the end of the cable passes between the slot 1 of the right wedge core 2 and the arc-shaped wire groove 1 of the shell 1, and then passes between the slot 2 of the left wedge core 4 and the arc-shaped wire groove 2 of the shell 1, and then the bidirectional threaded rod 6 is rotated so that the positive and negative threads of the bidirectional threaded rod 6 respectively cooperate with the positive and negative threaded holes of the right screw hole block 3 and the left screw hole block 5 to push the right wedge core 2 toward the lower end of the shell 1, and at the same time push the left wedge core 4 toward the upper end of the shell 1, so that the slot 1 of the right wedge core 2 clamps the outer end of the cable and presses it on the arc-shaped wire groove 1 of the shell 1, and at the same time the slot 2 of the left wedge core 4 clamps the inner end of the cable and presses it on the arc-shaped wire groove 2 of the shell 1, and then the two filling strips 12 are compressed and deformed, and the deformed two filling strips 12 fill in multiple pattern gaps between the cable and the shell 1 In the groove 13, the two locking screws 7 are rotated and tightened so that the two locking screws 7 respectively lock the right screw hole block 3 and the left screw hole block 5 on the bidirectional threaded rod 6, and the two wire clamps 18 respectively clamp the two ends of the cable to guide and support the two ends of the cable. When the outer end of the cable is subjected to a small pulling force, the elastic force of the torsion spring 19 buffers the swing of the cable and reduces the bending degree of the cable. Finally, when the outer end of the cable is subjected to a large pulling force, the outer end of the cable rubs against the slot 1 of the right wedge core 2, thereby pulling the right wedge core 2 downward, so that the right wedge core 2 is closer to the arc-shaped wire groove 1 of the shell 1, thereby clamping the outer end of the cable more tightly. At the same time, the inner end of the cable rubs against the slot 2 of the left wedge core 4, thereby pulling the left wedge core 4 upward, so that the left wedge core 4 is closer to the arc-shaped wire groove 2 of the shell 1, thereby clamping the inner end of the cable more tightly, thereby achieving self-locking clamping of both ends of the cable.

[0033] The main functions achieved by the present invention are:

[0034] 1. The two ends of the cable are clamped by split and oppositely moving wedge cores, which increases the clamping force of the cable, ensures the self-tightening clamping ability of the cable, and has good reliability;
