Description

Technical Field

[0001] The invention relates to the technical field of wire clamp devices, and in particular to a live working parallel groove wire clamp installation structure. Background Art

[0002] The parallel groove wire clamp is used for connecting aluminum stranded wire or steel core aluminum stranded wire of small and medium cross-section and steel stranded wire of overhead lightning arrester at the position where it does not bear tension, and is also used for jumper connection of non-linear pole tower. The power engineering material connecting wires is mainly used for power line engineering. The current conduction path between conductors: First, under the action of external pressure, the active aluminum oxide (Al2O3) layer on the aluminum-aluminum interface of the two conductors is squeezed or rubbed to cause it to partially rupture, so that the aluminum electrons flow freely between the peaks on the surface, forming a certain conductivity. The greater the pressure, the more peak-to-peak points of contact, and the smaller the contact resistance. In the installation and construction process of the wire clamp, it is required to apply conductive grease containing copper and silver ions on the surface of the conductor to prevent re-oxidation of the rupture points of the oxide layer. Second, the conductivity of the active Al2O3 itself makes the undamaged area also have a certain conductivity.

[0003] From the characteristics of metal materials, we know that under stress, the conductor will inevitably produce a certain amount of creep, which is more serious inside the parallel groove clamp where the local pressure is greater, causing the conductor to become slightly thinner and the diameter to decrease. If there is no proper compensation function, the grip of the parallel groove clamp on the conductor will decrease, resulting in stress relaxation.

[0004] For example, the Chinese invention patent with the announcement number CN110224239B provides a parallel groove wire clamp, which can better protect the stranded wire by adjusting the opening arc of the first upper clamp body and the second upper clamp body, and clamp the stranded wire by buckling the lower clamp body with the corresponding first upper clamp body and the second upper clamp body. However, after working for a long time, the stranded wire will become thinner after creeping, and the gripping force of the parallel groove wire clamp on the stranded wire will decrease, resulting in stress relaxation. At the same time, when the parallel groove wire clamp is used in the air, the length of the wire is very long. When it is blown by the wind, the wire swings with the wind, and the large-scale irregular swing will also affect the connection effect. Summary of the invention

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 8As shown, a live working parallel trench wire clamp installation structure provided by an embodiment of the present invention is used to connect two conductors installed horizontally between two adjacent distribution poles, including an outer cylinder 303 and a wire clamping mechanism, the conductor is arranged in the outer cylinder 303, the outer cylinder 303 is arranged along the axial direction of the conductor, the two ends of the outer cylinder 303 are the first end and the second end, the two distribution poles are the first distribution pole 100 and the second distribution pole, and the distance between the outer cylinder 303 and the first distribution pole 100 is smaller than the distance between the outer cylinder 303 and the second distribution pole. The second end of the outer cylinder 303 is located on the side closer to the first distribution pole 100 than the first end of the outer cylinder 303. The wire clamping mechanism includes an adjustment component, a threaded cylinder 302 and two clamps 201. The clamping body 201 is slidably disposed in the outer cylinder 303. The two clamping bodies 201 interlock with each other and clamp two wires. The two wires are the first wire 203 and the second wire 204. The length of the first wire 203 is greater than that of the second wire 204. The first wire 203 connects the adjacent first distribution pole 100 and the second distribution pole. One end of the second wire 204 is connected to the first distribution pole 100. The two clamping bodies 201 interlock with each other and clamp the other end of the second wire 204 and the first wire 203. The first wire 203 between the outer cylinder 303 and the second distribution pole sags due to gravity and drives the clamping body 201 to move toward the first end of the outer cylinder 303. A first arc groove is provided on one side of the clamping body 201 close to the second end of the outer cylinder 303. The two first arc grooves interlock with each other to form a first installation groove 311.

[0033] The adjustment assembly includes a turntable 310, a ratchet 305, a torsion spring 308, a first telescopic rod 307, a limiting unit and a plurality of second telescopic rods 304. The turntable 310 is rotatably disposed in the first mounting slot 311, and two connecting ropes 312 are fixedly disposed on the turntable 310, and the two connecting ropes 312 are respectively connected to the two clamps 201. The threaded cylinder 302 is disposed in the outer cylinder 303, and the threaded cylinder 302 and the outer cylinder 303 are threadedly matched, and the clamp 201 is disposed in the threaded cylinder 302, and the threaded cylinder 302 can rotate relative to the clamp 201, and the threaded cylinder 302 can drive the clamp 201 to move synchronously.

[0034] The ratchet 305 is slidably disposed in the outer cylinder 303. The ratchet 305 and the outer cylinder 303 are coaxially disposed. The ratchet 305 is disposed on one side of the threaded cylinder 302 close to the second end of the outer cylinder 303. The ratchet 305 can rotate around its own axis, and the limit unit allows the ratchet 305 to rotate in one direction. The first telescopic rod 307 and the second telescopic rod 304 are both disposed along the axial direction of the outer cylinder 303, and the first telescopic rod 307 and the second telescopic rod 304 are both telescopic. The first telescopic rod 307 is fixedly disposed on the ratchet 305, and the torsion spring 308 connects the rotating disk 310 and the first telescopic rod 307. A plurality of second telescopic rods 304 are distributed along the circumference of the outer cylinder 303, and the second telescopic rods 304 connect the ratchet 305 and the threaded cylinder 302.

[0035] During installation, the second wire 204 and the first wire 203 are tightened, the two clamps 201 are interlocked and clamp the second wire 204 and the first wire 203, and then the two clamps 201 are placed in the outer tube 303. In the initial state, the clamp 201 is close to the second end of the outer tube 303, and the first telescopic rod 307 is in a retracted state.

[0036] After installation, the first conductor 203 is relatively long. After a period of time, under the action of gravity, the first conductor 203 between the outer cylinder 303 and the second distribution pole sags due to gravity, and the second conductor 204 and the first conductor 203 continue to creep due to pressure, resulting in size changes. During the gradual sagging of the first conductor 203, the two clamps 201 and the threaded cylinder 302 are driven to move toward the first end of the outer cylinder 303. The threaded cylinder 302 rotates forward while moving. The threaded cylinder 302 first drives the second telescopic rod 304 to extend, and drives the ratchet 305 to rotate forward through the second telescopic rod 304. The ratchet 305 drives the turntable 310 to rotate forward through the first telescopic rod 307 and the torsion spring 308. The turntable 310 rotates to tighten the two connecting ropes 312 and further clamp the two clamps 201 to adapt to the creep of the second conductor 204 and the first conductor 203. After that, the turntable 310 stops rotating, and the first telescopic rod 307 continues to rotate, so that the torsion spring 308 accumulates force.

[0037] When the external wind force is strong, the drooping first conductor 203 will be tightened by the wind and swing, and the first conductor 203 drives the clamping body 201 and the threaded cylinder 302 to further move toward the first end of the outer cylinder 303, and the second telescopic rod 304 is stretched to the limit. The movement of the threaded cylinder 302 drives the ratchet 305 to move synchronously. At this time, the limit unit no longer restricts the rotation of the ratchet 305. Under the action of the torsion spring 308, the ratchet 305 reverses, and the ratchet 305 drives the threaded cylinder 302 to reverse through the second telescopic rod 304, thereby making the clamping body 201 and the threaded cylinder 302 move toward the second end of the outer cylinder 303, and pulling the first conductor 203 back and tightening it to reduce the shaking amplitude of the first conductor 203 and prevent the shaking amplitude from being too large to affect the connection effect of the first conductor 203 and the second conductor 204.

[0038] In this embodiment, the limiting unit includes a pawl 306 and a spring. One end of the pawl 306 is rotatably disposed on the outer cylinder 303 , and the other end of the pawl 306 is engaged with the ratchet teeth of the ratchet wheel 305 . The spring connects the pawl 306 and the outer cylinder 303 .

[0039] In this embodiment, the clamping mechanism further includes a fixing assembly, which includes two filling fixing blocks 301, which are interlocked and arranged in the threaded barrel 302. A first stopper 350 is fixedly arranged on one side of each filling fixing block 301 close to the first end of the outer barrel 303, and the first stopper 350 is used to abut against one end of the threaded barrel 302. A detachable second stopper is arranged on one side of each filling fixing block 301 close to the second end of the outer barrel 303, and the second stopper is used to abut against the other end of the threaded barrel 302.

[0040] A second arc groove is provided on the filling and fixing block 301, and the second arc groove is arranged along the axial direction of the outer cylinder 303. The two second arc grooves are interlocked and combined to form a second installation groove 320, and the two clamps 201 are arranged in the second installation groove 320. When the first wire 203 drives the two clamps 201 to move toward the first end of the outer cylinder 303, the clamps 201 drive the filling and fixing block 301 and the threaded cylinder 302 to move synchronously, and the first telescopic rod 307 and the second telescopic rod 304 gradually extend, and the ratchet 305 does not move at this time. In addition, due to the threaded matching between the threaded cylinder 302 and the outer cylinder 303, the threaded cylinder 302 rotates forward when moving toward the first end of the outer cylinder 303, and the threaded cylinder 302 drives the ratchet 305 to rotate forward through the second telescopic rod 304.

[0041] When the external wind force is strong, the first wire 203 drives the two clamps 201 and the threaded tube 302 to move further toward the first end of the outer tube 303. However, since the first telescopic rod 307 and the second telescopic rod 304 are extended to the extreme position, the further movement of the threaded tube 302 will drive the ratchet 305 to move, causing the ratchet 305 and the pawl 306 to disengage.

[0042] In this embodiment, two third arc grooves are formed on each clamp body 201, and the two third arc grooves are distributed along the circumference of the outer tube 303. The third arc grooves are arranged along the axial direction of the outer tube 303. A third arc groove on each clamp body 201 and a third arc groove on another clamp body 201 are buckled together to form a third installation groove 321, and each wire is arranged in a third installation groove 321.

[0043] In this embodiment, the clamping mechanism further includes a reset unit, which includes a first connection disk 330 and a plurality of tension springs 309. The first connection disk 330 is rotatably disposed at the second end of the outer cylinder 303, and the first connection disk 330 and the outer cylinder 303 are coaxially disposed. The first connection disk 330 is disposed on a side of the ratchet 305 away from the threaded cylinder 302. The plurality of tension springs 309 are distributed along the circumference of the first connection disk 330, and the tension springs 309 connect the first connection disk 330 and the ratchet 305.

[0044] When the ratchet 305 reverses and moves toward the first end of the outer tube 303, the ratchet 305 and the pawl 306 are disengaged. After the ratchet 305 stops rotating, the ratchet 305 moves toward the second end of the outer tube 303 under the action of the tension spring 309, and re-engages with the pawl 306 after resetting.

[0045] In this embodiment, the outer cylinder 303 includes two half cylinders 3031 that are interlocked with each other. Each half cylinder 3031 is provided with a fourth arc groove. The two fourth arc grooves are interlocked with each other. The first connecting plate 330 is rotatably disposed in the two fourth arc grooves.

[0046] In this embodiment, the two filling fixing blocks 301 are connected by first bolts, the two clamping bodies 201 are connected by a plurality of second bolts 205 , and the two half-tubes 3031 are connected by third bolts.

[0047] In this embodiment, the first telescopic rod 307 is arranged along the axial direction of the outer tube 303. The first telescopic rod 307 includes a connecting rod and a sleeve. The connecting rod is slidably arranged in the sleeve, and the connecting rod and the sleeve are spline-matched so that the connecting rod and the sleeve can move relative to each other and rotate synchronously.

[0048] In this embodiment, a connecting shaft is fixedly provided on one side of the rotating disk 310 close to the clamping body 201, and a second connecting disk 340 is fixedly provided on the connecting shaft. The rotating disk 310, the connecting shaft and the second connecting disk 340 are coaxially arranged. The clamping body 201 is also provided with a fifth arc groove and a sixth arc groove. The first arc groove, the fifth arc groove and the sixth arc groove are sequentially distributed along the direction from the second end to the first end of the outer cylinder 303, and the first arc groove, the fifth arc groove and the sixth arc groove are connected. The two fifth arc grooves are interlocked with each other, the two sixth arc grooves are interlocked with each other, the connecting shaft is arranged in the fifth arc groove, and the second connecting disk 340 is rotatably arranged in the sixth arc groove, so that the rotating disk 310 can rotate relative to the clamping body 201 and can move synchronously with the clamping body 201.

[0049] In this embodiment, a pulling rod 206 is fixedly provided on one side of each clamping body 201 close to the second end of the outer tube 303 , and the pulling rope is fixedly connected to the pulling rod 206 .

[0050] The working process of a live working parallel groove wire clamp installation structure: during installation, the second wire 204 and the first wire 203 are tightened, the two clamp bodies 201 are buckled together, each wire is in a third installation groove 321, and then the two filling fixing blocks 301 are buckled together on the outside of the two clamp bodies 201, and the threaded cylinder 302 is sleeved on the outside of the two filling fixing blocks 301, and finally the two half cylinders 3031 are buckled together on the outside of the threaded cylinder 302. In the initial state, the clamp body 201 is close to the second end of the outer cylinder 303, the first telescopic rod 307 and the second telescopic rod 304 are in a retracted state, and the pawl 306 and the ratchet 305 are in ratchet cooperation.

[0051] After installation, since the first conductor 203 is relatively long, after a period of time, under the action of gravity, the first conductor 203 between the outer tube 303 and the second distribution pole sags due to gravity, and at the same time, the second conductor 204 and the first conductor 203 continue to creep due to pressure, resulting in changes in size.

[0052] As the first conductor 203 gradually droops, the two clamps 201 are driven to move toward the first end of the outer cylinder 303. The clamps 201 drive the filling fixed block 301 and the threaded cylinder 302 to move synchronously. The first telescopic rod 307 and the second telescopic rod 304 gradually extend. At this time, the ratchet 305 does not move. In addition, due to the threaded fit between the threaded cylinder 302 and the outer cylinder 303, the threaded cylinder 302 rotates forward when moving toward the first end of the outer cylinder 303. The threaded cylinder 302 drives the ratchet 305 to rotate forward through the second telescopic rod 304. The ratchet 305 drives the rotating disk 310 to rotate forward through the first telescopic rod 307 and the torsion spring 308. The rotating disk 310 rotates to tighten the two connecting ropes 312 and further clamp the two clamps 201 to adapt to the creep of the second conductor 204 and the first conductor 203. After that, the rotating disk 310 stops rotating, and the first telescopic rod 307 continues to rotate, so that the torsion spring 308 accumulates force, and because the pawl 306 restricts the one-way rotation of the ratchet 305, the ratchet 305 will not reverse and reset under the action of the torsion spring 308.

[0053] When the external wind is strong, the drooping first conductor 203 will be tightened by the wind and swing, and the first conductor 203 drives the two clamps 201 and the threaded tube 302 to move further toward the first end of the outer tube 303. However, since the first telescopic rod 307 and the second telescopic rod 304 are extended to the extreme position, the further movement of the threaded tube 302 will drive the ratchet 305 to move, so that the ratchet 305 and the pawl 306 are disengaged.

[0054] At this time, the torsion spring 308 is reset, and the torsion spring 308 drives the rotating disk 310 and the ratchet 305 to rotate in the opposite direction. The rotating disk 310 rotates in the opposite direction until the connecting rope 312 is tightened again, and then stops rotating. The ratchet 305 rotates in the opposite direction, and drives the threaded cylinder 302 to rotate in the opposite direction through the second telescopic rod 304. When the threaded cylinder 302 rotates in the opposite direction, it moves toward the second end of the outer cylinder 303. The threaded cylinder 302 drives the two clamps 201 to move synchronously, and pulls the first wire 203 back and tightens it, so as to reduce the shaking amplitude of the first wire 203, and prevent the shaking amplitude from being too large to affect the connection effect between the first wire 203 and the second wire 204.

[0055] When the ratchet wheel 305 stops rotating, the ratchet wheel 305 moves under the action of the tension spring 309, and is re-matched with the pawl 306 after being reset. When the wind force decreases, the first wire 203 accumulates force in the torsion spring 308 again due to its own weight.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
