Description

Technical Field

[0001] The invention relates to the technical field of electric power fittings, in particular to a double suspension wire clamp. Background Art

[0002] The suspension clamp is a hardware that suspends the conductor (ground) wire to the suspension insulator string (group) or hardware string (group). In order to improve the reliability of cable suspension, a variety of double vertical clamps have been proposed in the prior art, such as a pre-twisted double suspension clamp proposed in the Chinese invention patent with publication number CN117353230B. The double vertical clamp uses spring 2 to squeeze the arc-shaped clamp plate against the fixed rod, and then through the opening of the clamping slot, there is a certain gap. In this gap, the squeezing force disappears, and the elastic potential energy of spring 1 is released, so that the clamp block is clamped into the clamping slot, and the horizontal section of the clamp block is set at a right angle to effectively increase the contact area with the clamping slot, and then firmly fix the fixed rod, so as to complete the installation work between the various mechanisms. By directly installing and fixing the pre-installed clamp through the "T"-shaped mounting block, it can effectively avoid the situation of multiple accessories being installed at the same time, and the pressure can effectively prevent it from loosening and the connection from being loose; the spacing between the two installation and fixing components can be adjusted according to the actual use situation by adjusting the component, effectively meeting different use requirements.

[0003] In actual situations, after the cable is clamped by the two vertical clamps, the two ends of the cable will naturally bend and sag, thereby driving the two vertical clamps to be arranged in an A shape, so that the cable between the two vertical clamps is lifted up. When the cable is subjected to external force and fluctuates, the cable end on one side of the two vertical clamps will rise while the cable end on the other side will fall, thus causing the inner end of one vertical clamp to tilt downward and the inner end of the other vertical clamp to tilt upward. At this time, the ends of the cable between the two vertical clamps will be twisted and bent in opposite directions, resulting in greater bending damage to both ends of the cable between the two vertical clamps. Therefore, it is practical to propose a double suspension clamp in which the two vertical clamps are synchronously tilted relative to each other to reduce local bending damage to the cable. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a double vertical line clamp which always maintains an eight-shaped relative arrangement, reduces cable bending damage when the cable is subjected to unbalanced force, and has good practicality.

[0005] A double suspension wire clamp of the present invention comprises a suspension plate and a hanger, wherein the lower end of the hanger is rotatably connected to the middle part of the suspension plate; further comprising two wire clamp assemblies, two rotating shafts, a swing arm 1, a swing arm 2 and a pull rod, wherein the two wire clamp assemblies are used to clamp cables, the middle parts of the two wire clamp assemblies are both equipped with rotating shafts, and the two wire clamp assemblies are rotatably installed on the left and right ends of the suspension plate through the two rotating shafts, the upper end of the swing arm 1 is fixedly connected to the rotating shaft on the wire clamp assembly at the left end, the lower end of the swing arm 2 is fixedly connected to the rotating shaft on the wire clamp assembly at the right end, and the swing arm 1 and the swing arm 2 are respectively connected to the two The wire clamp assembly is vertically arranged, the left end of the pull rod is rotatably connected to the lower end of the swing arm 1, and the right end of the pull rod is rotatably connected to the upper end of the swing arm 2; the hanger is connected to the power tower pole, so that the two hanging plates and the two wire clamp assemblies are suspended below the tower pole, the cables are clamped on the two wire clamp assemblies, and the cables are hung up.

When the cables are subjected to fluctuations or the cables on both sides of the two wire clamp assemblies are subjected to uneven tension, the cables on both sides of the two wire clamp assemblies will be curved. The cable clamp assembly on the right side is changed and has different heights. When the cable on the outside of the cable clamp assembly on the right side is higher than the cable on the outside of the cable clamp assembly on the left side, the cable pulling force on the cable clamp assembly on the right side is reduced, so that the inner end of the right cable clamp assembly tends to fall and drives the swing arm 2 thereon to swing inward. At the same time, the cable pulling force on the cable clamp assembly on the left side is increased, so that the inner end of the left cable clamp assembly tends to rise and drives the swing arm 1 thereon to swing inward. Since the cable pulling force on the right cable clamp assembly is smaller than that on the left cable clamp assembly, Therefore, at this time, the force applied by swing arm one to the pull rod is greater than the force applied by swing arm two to the pull rod, so that swing arm one pushes swing arm two to swing outward through the pull rod, thereby causing the inner end of the wire clamp assembly located on the higher side of the cable to rise as well.

DETAILED DESCRIPTION

[0027] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. Example 1

[0028] like Figures 1 to 4As shown, a double suspension wire clamp comprises a suspension plate 1 and a hanger 2, wherein the lower end of the hanger 2 is rotatably connected to the middle of the suspension plate 1; further comprising two wire clamp assemblies 3, two rotating shafts 4, a swing arm 1 5, a swing arm 2 6 and a pull rod 7, wherein the two wire clamp assemblies 3 are used to clamp cables, the middle parts of the two wire clamp assemblies 3 are both equipped with a rotating shaft 4, and the two wire clamp assemblies 3 are rotatably installed on the left and right ends of the suspension plate 1 through the two rotating shafts 4, the upper end of the swing arm 1 5 is fixedly connected to the rotating shaft 4 on the wire clamp assembly 3 at the left end, and the lower end of the swing arm 2 6 is fixedly connected to the rotating shaft 4 on the wire clamp assembly 3 at the right end The swing arm 1 5 and the swing arm 2 6 are respectively vertically arranged with the two wire clamp assemblies 3, the left end of the pull rod 7 is rotatably connected to the lower end of the swing arm 1 5, and the right end of the pull rod 7 is rotatably connected to the upper end of the swing arm 2 6; it also includes two slides 23, an upper roller 24 and a lower roller 25, vertical slide grooves are arranged on both sides of the middle part of the suspension plate 1, the two slides 23 are respectively slidably installed in the two vertical slide grooves of the suspension plate 1, the upper roller 24 is rotatably installed at the upper part between the two slides 23, and the lower roller 25 is rotatably installed at the lower part between the two slides 23, and the cable passes between the upper roller 24 and the lower roller 25.

[0029] The hanger 2 is connected to the power tower so that the two hanging plates 1 and the two wire clamp assemblies 3 are suspended under the tower, and the cables are clamped on the two wire clamp assemblies 3 to hang the cables. In a natural state, the cables on the outside of the two wire clamp assemblies 3 are bent downward into an arc shape, and the two wire clamp assemblies 3 are arranged relative to each other in an eight-shaped shape. When the cables are subjected to fluctuations or the cables on both sides of the two wire clamp assemblies 3 are subjected to unbalanced tension, the arc shapes of the cables on both sides of the two wire clamp assemblies 3 will change and their heights will be different. When the cables on the outside of the right wire clamp assembly 3 are higher than the cables on the outside of the left wire clamp assembly 3, the pulling force of the cables on the right wire clamp assembly 3 is reduced, so that the inner end of the right wire clamp assembly 3 tends to descend and drives the swing arm 2 6 thereon to swing inward. At the same time, the pulling force of the cables on the left wire clamp assembly 3 is increased, so that the inner end of the left wire clamp assembly 3 tends to rise. And it drives the swing arm 1 5 on it to have an inward tendency. Since the cable pulling force on the right wire clamp assembly 3 is smaller than the cable pulling force on the left wire clamp assembly 3, the force applied by the swing arm 1 5 to the pull rod 7 is greater than the force applied by the swing arm 2 6 to the pull rod 7, so that the swing arm 1 5 pushes the swing arm 2 6 to swing outward through the pull rod 7, so that the inner end of the wire clamp assembly 3 located on the higher side of the cable also rises, so that the two wire clamp assemblies 3 still maintain an eight-shaped relative arrangement when the cable is subjected to fluctuating or unbalanced tension, but the relative angle of the two wire clamp assemblies 3 changes, thereby preventing the two ends of the cable between the two wire clamp assemblies 3 from being twisted and bent in opposite directions. The upper roller 24 and the lower roller 25 roll and guide the cable between the two wire supporting seats 8, avoiding the cable between the two wire supporting seats 8 from swinging back and forth, and reducing the bending damage of the two ends of the cable between the two wire clamp assemblies 3.

[0031] The wire supporting trough tube 11 is slidably installed in the wire supporting seat 8 through a plurality of rollers 17, the wire supporting trough tube 11 supports the bottom of the cable, the wire pressing trough tube 12 is buckled on the top of the cable, and the wire pressing trough tube 12 is slid toward the wire supporting trough tube 11, so that the two insertion strips 15 are respectively slidably inserted into the two slots 16, and the guiding effect of the insertion strips 15 and the slots 16 on the wire supporting trough tube 11 and the wire pressing trough tube 12 facilitates the rapid alignment of the wire supporting trough tube 11 and the wire pressing trough tube 12. When the wire supporting trough tube 11 and the wire pressing trough tube 12 are aligned, the wire supporting trough tube 11 and the wire pressing trough tube 12 are screwed and fastened by a plurality of bolts 13, so that the two insertion strips 15 are respectively moved in the movable margin of the two slots 16, so that the wire supporting trough tube 11 and the wire pressing trough tube 12 are relatively close to the distance of the movable margin, thereby tightening the cable, and the cover plate 10 is installed The opening of the wire supporting seat 8 allows the wire supporting seat 8 to bear the wire clamp assembly 9, and the wire supporting seat 8 and the cover plate 10 protect the wire clamp assembly 9, so that when the angles of the two wire supporting seats 8 change relatively, a plurality of limiting bosses 14 limit the sliding of the two wire supporting trough tubes 11 on the two wire supporting seats 8 to prevent the wire clamps formed by the two wire supporting trough tubes 11 and the two pressing wire trough tubes 12 from sliding too much on the two wire supporting seats 8 and causing derailment. The curvature and length of the cable between the two wire supporting seats 8 can be adaptively changed, thereby further reducing the bending of the ends of the cables between the two wire supporting seats 8. By setting a plurality of rollers 17, the friction and wear of the two wire supporting seats 8 and the two wire supporting trough tubes 11 are reduced. By setting a plurality of water flow holes 18, rainwater in the two wire supporting seats 8 can be easily discharged, thereby reducing rainwater residue and rust. Example 3

[0032] like Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, on the basis of Example 1, it also includes two sliders 19 and two limiting slide grooves 26, the limiting slide grooves 26 are arranged on the top of the outer wall of the two wire pressing groove tubes 12, the sliders 19 are installed in the middle of the lower end surfaces of the two cover plates 10, and the lower ends of the two sliders 19 are respectively slidably connected with the two limiting slide grooves 26; it also includes four shock-absorbing springs 20, four open end blocks 21 and four bayonet pins 22, the inner ends of the two shock-absorbing springs 20 are respectively rotatably connected with the two ends of the two sliders 19, the outer ends of the two shock-absorbing springs 20 are installed with open end blocks 21, and the two ends of the outer wall tops of the two wire pressing groove tubes 12 are installed with bayonet pins 22, and the four bayonet pins 22 are respectively matched and aligned with the two open end blocks 21.

[0033] When installing the cover plate 10 onto the opening of the wire supporting seat 8, first clamp the two open end blocks 21 onto the two bayonet pins 22 respectively. When the cover plate 10 is fastened to the wire supporting seat 8, the two shock-absorbing springs 20 are compressed and laid flat, so that the slider 19 supports the wire pressing trough tube 12 through the elastic force of the two shock-absorbing springs 20, and then the wire clamp composed of the wire supporting trough tube 11 and the wire pressing trough tube 12 elastically supports the cable, and buffers the cable part between the two wire supporting seats 8. The two sliders 19 are slidably connected with the two limiting slide grooves 26, so as to guide and limit the wire clamp composed of the two wire supporting trough tubes 11 and the two wire pressing trough tubes 12, so as to prevent the wire clamp from rotating and improve stability.

[0034] like Figures 1 to 10As shown, a double suspension wire clamp of the present invention, when working, first connects the hanger 2 to the power tower pole, so that the two hanging plates 1 and the two wire clamp assemblies 3 are suspended below the tower pole, the wire supporting trough tube 11 supports the bottom of the cable, the wire pressing trough tube 12 is buckled on the top of the cable, and the wire pressing trough tube 12 is slid toward the wire supporting trough tube 11, so that the two insertion strips 15 are slidably inserted in the two slots 16 respectively, and the guiding effect of the insertion strips 15 and the slots 16 on the wire supporting trough tube 11 and the wire pressing trough tube 12 facilitates the rapid alignment of the wire supporting trough tube 11 and the wire pressing trough tube 12. When the wire supporting trough tube 11 and the wire pressing trough tube 12 are aligned, the wire supporting trough tube 11 and the wire pressing trough tube 12 are screwed and fastened by multiple bolts 13, so that the two insertion strips 15 are respectively in the two slots 16 The two open end blocks 21 are respectively mounted on the two bayonet pins 22. After the cover plate 10 is fastened to the wire supporting seat 8, the two damping springs 20 are compressed and laid flat, so that the slider 19 supports the wire pressing trough tube 12 through the elastic force of the two damping springs 20, thereby making the wire clamp formed by the wire supporting trough tube 11 and the wire pressing trough tube 12 elastically support the cable, buffer the cable part between the two wire supporting seats 8, suspend the cable, and then under the natural state, the cables outside the two wire supporting seats 8 are bent downward into an arc shape. The two wire supporting seats 8 are arranged relative to each other in an eight-shaped shape. When the cable is subjected to fluctuations or the two sides of the two wire supporting seats 8 When the pulling force on the cables is uneven, the arc shape of the cables on both sides of the two cable support seats 8 will change and the heights will be different. When the cable on the outside of the right cable support seat 8 is higher than the cable on the outside of the left cable support seat 8, the cable pulling force on the right cable support seat 8 is reduced, so that the inner end of the right cable support seat 8 tends to decline and drives the swing arm 2 6 thereon to swing inward. At the same time, the cable pulling force on the left cable support seat 8 increases, so that the inner end of the left cable support seat 8 tends to rise and drives the swing arm 1 5 thereon to tend inward. Since the cable pulling force on the right cable support seat 8 is smaller than that on the left cable support seat 8, the force applied by the swing arm 1 5 to the pull rod 7 is greater than the force applied by the swing arm 2 6 to the pull rod The force applied by the rod 7 causes the swing arm 1 5 to push the swing arm 2 6 to swing outward through the pull rod 7, so that the inner end of the wire support seat 8 located on the higher side of the cable also rises, so that the two wire support seats 8 still maintain an eight-shaped relative arrangement when the cable is subjected to fluctuating or unbalanced tension, and only the relative angle of the two wire clamp assemblies 3 changes, thereby preventing the two ends of the cable between the two wire clamp assemblies 3 from being twisted and bent in opposite directions. Finally, when the angles of the two wire support seats 8 change relatively, the two wire supporting trough tubes 11 slide along the two wire support seats 8 under the rolling support of multiple rollers 17, and the curvature and length of the cable between the two wire support seats 8 are adaptively changed, thereby reducing the bending damage to the two ends of the cable between the two wire support seats 8.

[0035] The main functions achieved by the present invention are:

[0036] 1. The double vertical cable clamps are always arranged in an eight-shaped relative arrangement to reduce cable bending damage when the cable is subjected to unbalanced force;

[0037] 2. The wire clamp structure improves the clamping reliability of the cable by cooperating with the slide bar and the slide groove with movable margin;
