Description

Technical Field

[0001] The present invention relates to the technical field of cable tensioners, and in particular to an intelligent cable tensioner and a cable tensioning method thereof. Background Art

[0002] The tensioner terminal is an important tool used to tighten and fix wires and cables in power line construction. It is usually designed for the end of the power line or a position that needs special fixation to ensure that the wires and cables remain stable in the tightened state and prevent them from loosening or falling off due to external forces.

[0003] The structure of the tensioner terminal usually includes a metal frame to provide sufficient strength and stability; and one or more locking mechanisms to firmly fix the wires and cables to the frame. In addition, in order to ensure the insulation performance of the wires and cables, the parts of the tensioner terminal that contact the wires and cables are usually injection-molded with insulating materials.

[0004] For example, a Chinese patent document with the announcement number CN210927024U discloses a terminal tensioner, including: a first tensioning assembly and a second tensioning assembly, the second tensioning assembly is clamped on the first tensioning assembly; the first tensioning assembly includes a first tensioning piece and a first tensioning shell, the first tensioning shell is sleeved on the first tensioning piece; wherein the first tensioning piece, the first tensioning shell and the second tensioning assembly together constitute a tensioning area. By using the first tensioning assembly and the second tensioning assembly in coordination, the terminal cable is placed in the tensioning area composed of the first tensioning piece, the first tensioning shell and the second tensioning assembly for fixing, which not only solves the problem of high work intensity of the traditional bundling method, reduces manual operation fatigue, but also improves work efficiency.

[0005] Although the technical solution described in the above patent solves the problem of high work intensity of the traditional bundling method, it still has the following shortcomings in actual use:

[0006] Since the tensioner terminal is usually used to tie and fix the terminal of the wire and cable, after the terminal of the wire and cable is tied, since the middle part of the wire and cable is in a suspended state, its own gravity will generate a pulling force on the tensioner. Under normal circumstances, since the friction between the tensioner and the wire and cable is greater than the above-mentioned pulling force, there will be no relative sliding between the tensioner and the wire and cable, and the tensioner maintains the binding and fixing effect on the wire and cable. However, with the passage of time, the tensioner itself will age or corrode. At this time, the friction between the tensioner and the wire and cable may gradually decrease. Once the friction between the tensioner and the wire and cable is reduced to less than the above-mentioned pulling force, the tensioner and the wire and cable will slide relative to each other under the action of the pulling force, causing the tensioner to lose its binding and fixing effect on the wire and cable terminal, and the wire and cable terminal will slip off the tensioner, which may easily lead to safety accidents. Summary of the invention

[0015] Preferably, the front end of one of the clamping blocks and the rear end of the other clamping block are both fixedly connected to a limiting rod, and the limiting rod has an intermediate rod body, and both ends of the intermediate rod body are in contact with the intermediate block.

[0016] Preferably, the limiting rod further comprises end rod bodies extending outward from both ends of the intermediate rod body, and an empty groove is formed between the end rod bodies and the intermediate block;

[0017] Two force-bearing plates are fixed on a side of the cover plate away from the main body, and two clearance grooves are provided on the cover plate;

[0018] The end rod body extends to the inside of the clearance groove, and a gap is left between the end of the end rod body and the inner wall of the clearance groove;

[0019] The end rod body is located between the force-bearing plate and the main body.

[0020] Preferably, a slide groove is provided on the side of the second shell, and a sliding block corresponding to the slide groove is fixed on the force-bearing plate, and the sliding block is slidably inserted in the slide groove in an interference fit manner.

[0023] Preferably, connection blocks are fixed on both sides of the middle block, and the U-shaped ribs pass through the circular holes opened on the connection blocks.

[0024] A line tightening method, based on the above-mentioned intelligent line tightening device, comprises the following steps:

[0025] S1. Remove the second housing and the middle component, and make the terminal end of the wire pass through the U-shaped rib;

[0026] S2, using the middle component to push down the terminal end of the wire so that the terminal end of the wire is pressed onto the first housing by the clamping block at the bottom of the middle component, and then bending the wire so that the middle part of the wire and the terminal end of the wire are roughly parallel, and the middle part of the wire contacts the clamping block at the top of the middle component;

[0030] S6. Align the slider and insert it into the slide slot to complete the installation of the cover plate.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention provides an intermediate component in the wire tightening area, and uses the intermediate component to support between the middle part of the wire and the terminal part of the wire, so that the middle part of the wire and the terminal part of the wire are respectively in contact with the two clamping blocks. After the main body cooperates with the intermediate component to clamp the middle part of the wire and the terminal part of the wire, the middle part of the wire will cause the clamping block located at the top of the intermediate component to have a tendency to move forward due to its own gravity. However, since the present invention also provides an inclined plate that can rotate around the intermediate axis, and the upper and lower ends of the inclined plate are respectively hinged to the two clamping blocks, once the clamping block located at the top of the intermediate component moves forward or the clamping block located at the bottom of the intermediate component moves backward, the top of the inclined plate will be driven to flip forward, so that the distance between the two clamping blocks is increased, that is, the squeezing force of the two clamping blocks on the middle part of the wire and the terminal part of the wire is increased. Under this structure, even if the main body is aged and the second shell is loosened, it can ensure that the middle part of the wire and the terminal part of the wire remain in a state of being tied and fixed by the main body, and the middle part of the wire and the terminal part of the wire will not slip off the main body, thereby ensuring safety.

[0033] 2. The cover plate of the present invention is used to shield the first reflector and the second reflector, so that when the displacement of the clamping block does not exceed a predetermined value, the first reflector and the second reflector will be covered and shielded by the cover plate. At this time, the first reflector and the second reflector will not generate any reflection because they are covered and shielded by the cover plate. However, once the displacement of the clamping block exceeds a predetermined value, the cover plate will be squeezed by the clamping block and fall off the main body. At this time, the first reflector and the second reflector are exposed to the external environment and can reflect the light in the external environment. If the maintenance personnel can observe the light reflected by the first reflector and the second reflector, it indicates that the displacement of the clamping block exceeds the predetermined value, that is, the binding and fixing effect of the main body on the middle part and the terminal part of the wire is about to fail, and the staff needs to replace the main body immediately to prevent a dangerous situation from occurring.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0048] See also Figure 1-Figure 12, the present invention provides a technical solution:

[0049] An intelligent tensioner includes a main body 1. The main body 1 and a first shell 11, a second shell 12, a tensioning area 13 and a U-shaped rib 14 arranged thereon are all prior arts and will not be described in detail herein. Different from the prior art, an intermediate component 2 is provided in the tightening area 13 between the first shell 11 and the second shell 12 of the main body 1, and the upper and lower ends of the intermediate component 2 press the wire middle part 41 and the wire terminal part 42 against the first shell 11 and the second shell 12 respectively to fix the wire middle part 41 and the wire terminal part 42, wherein the wire middle part 41 and the wire terminal part 42 are different parts on the same wire and cable. Specifically, in this embodiment, the end of the same wire and cable is defined as the wire terminal part 42, and the part of the same wire and cable excluding the wire terminal part 42 is defined as the wire middle part 41. In actual use, the intermediate component 2 is supported between the wire middle part 41 and the wire terminal part 42, and monitors whether the wire middle part 41 and the wire terminal part 42 are displaced after being clamped. The specific monitoring principle is described in detail below.

[0050] The intermediate component 2 is slidably connected to the U-shaped rib 14 of the main body 1, and includes an intermediate block 21, clamping blocks 22 respectively arranged at the upper and lower ends of the intermediate block 21, and an inclined plate 23 arranged inside the intermediate block 21 and between the two clamping blocks 22, wherein the intermediate block 21 and the clamping block 22 are both made of insulating materials (for example, the same material as the first shell 11 and the second shell 12), and a vertically penetrating communication chamber 212 is formed inside the intermediate block 21, such as Figure 8 and Fig. 9 As shown, the inclined plate 23 is arranged inside the connecting chamber 212, and a horizontally arranged intermediate shaft 231 is fixed inside the connecting chamber 212. The inclined plate 23 can rotate around the axis of the intermediate shaft 231, and the upper and lower ends of the inclined plate 23 are respectively hinged to the two clamping blocks 22.

[0051] In the above scheme, by arranging the intermediate component 2 in the tightening area 13, and using the intermediate component 2 to support between the wire middle part 41 and the wire terminal part 42, the wire middle part 41 and the wire terminal part 42 are respectively in contact with the two clamping blocks 22. After the main body 1 cooperates with the intermediate component 2 to clamp the wire middle part 41 and the wire terminal part 42, the wire middle part 41 will cause the clamping block 22 located at the top of the intermediate component 2 to move forward due to its own gravity. However, since the present invention is also provided with an inclined plate 23 that can rotate around the intermediate shaft 231, and the upper and lower ends of the inclined plate 23 are respectively hinged to the two clamping blocks 22, Once the clamping block 22 at the top of the middle component 2 moves forward or the clamping block 22 at the bottom of the middle component 2 moves backward, the top of the inclined plate 23 will be driven to flip forward, so that the distance between the two clamping blocks 22 increases, that is, the squeezing force of the two clamping blocks 22 on the middle portion 41 of the wire and the terminal portion 42 of the wire increases. Under this structure, even if the main body 1 ages or other conditions cause the second shell 12 to loosen, it can ensure that the middle portion 41 of the wire and the terminal portion 42 of the wire remain tightly fixed by the main body 1, and the middle portion 41 of the wire and the terminal portion 42 of the wire will not slip off the main body 1, thereby ensuring safety.

[0052] Furthermore, grooves 211 recessed toward the middle of the middle block 21 are provided on both upper and lower end surfaces of the middle block 21, and both ends of the connecting chamber 212 are respectively connected to the two grooves 211, and the two clamping blocks 22 are respectively arranged inside the two grooves 211 in an interference fit manner; specifically, the purpose of the clamping blocks 22 being arranged inside the two grooves 211 in an interference fit manner is to utilize the friction force between the clamping blocks 22 and the inner wall surface of the grooves 211 to fix the position of the clamping blocks 22, so that the clamping blocks 22 can be kept inside the grooves 211 when the cables are not clamped.

[0053] The front end of one clamping block 22 (i.e., the clamping block 22 located at the top of the middle component 2) and the rear end of the other clamping block 22 (i.e., the clamping block 22 located at the bottom of the middle component 2) are fixedly connected to the limit rod 24, and the limit rod 24 has an intermediate rod body 241, and both ends of the intermediate rod body 241 are in contact with the middle block 21. Figure 6 As shown, therefore, the intermediate rod body 241 has the function of limiting the position of the clamping block 22. For example, the clamping block 22 located at the top of the intermediate component 2 cannot move backward due to the limitation of the intermediate rod body 241, and the clamping block 22 located at the bottom of the intermediate component 2 cannot move forward due to the limitation of the intermediate rod body 241.

[0054] The two sides where the two clamping blocks 22 are separated are both provided with arc grooves 221. The setting of the arc grooves 221 is beneficial to increasing the contact area between the clamping block 22 and the middle part 41 of the wire and the terminal part 42 of the wire. A receiving groove 222 is provided on the inner arc surface of the arc groove 221. The setting of the receiving groove 222 increases the roughness of the inner arc surface of the arc groove 221, thereby increasing the friction between the clamping block 22 and the middle part 41 of the wire and the terminal part 42 of the wire. The top of the inclined plate 23 is hinged with a second fixed block 234 through an end shaft 233. The second fixed block 234 is fixedly connected to the clamping block 22 through a bolt 235. The head of the bolt 235 is located inside the receiving groove 222, and the internal sealing of the receiving groove 222 is provided with a sealing plate 223. The sealing plate 223 is used to prevent rainwater and the like from entering the interior of the receiving groove 222, thereby helping to prevent the bolt 235 from being oxidized and rusted by rainwater.

[0055] First fixing blocks 232 are fixed to both ends of the intermediate shaft 231 , and the first fixing blocks 232 are fixedly installed inside the communicating chamber 212 .

[0056] Connecting blocks 25 are fixed on both sides of the middle block 21 , and the U-shaped ribs 14 pass through the circular holes 251 provided on the connecting blocks 25 , so that the middle block 21 can slide on the U-shaped ribs 14 .

[0057] The principle of monitoring whether the wire intermediate portion 41 and the wire terminal portion 42 are displaced after being clamped is as follows.

[0058] The wire tensioner also includes a warning component 3, which is used to issue an alarm when the clamping block 22 moves relative to the middle block 21. Since the movement of the clamping block 22 relative to the middle block 21 necessarily represents that the middle portion 41 of the wire and the terminal portion 42 of the wire have been displaced after being clamped, the warning component 3 is used to monitor whether the middle portion 41 of the wire and the terminal portion 42 of the wire have been displaced after being clamped.

[0059] Specifically, the warning component 3 includes a second reflector 33 fixed to the front and rear end surfaces of the first shell 11, a first reflector 32 fixed to the front and rear end surfaces of the second shell 12, and a cover plate 31 arranged at the front and rear ends of the main body 1 and used to cover and shield the corresponding first reflector 32 and second reflector 33 respectively, wherein the first reflector 32 and the second reflector 33 can adopt a reflective film and then be fixed to the main body 1 by pasting; the cover plate 31 is connected to the main body 1, and when the clamping block 22 moves a predetermined distance relative to the middle block 21, the cover plate 31 is squeezed by the clamping block 22 and falls off the main body 1; the cover plate 31 is used to shield the first reflector 32 and the second reflector 33, so that when the displacement of the clamping block 22 does not exceed a predetermined value, the first reflector Both the first reflector 32 and the second reflector 33 will be covered and blocked by the cover plate 31. At this time, the first reflector 32 and the second reflector 33 will not produce any reflection because they are covered and blocked by the cover plate 31. However, once the displacement of the clamping block 22 exceeds the predetermined value, the cover plate 31 will be squeezed by the clamping block 22 and fall off the main body 1. At this time, the first reflector 32 and the second reflector 33 are exposed to the external environment and can reflect the light in the external environment. If the maintenance personnel can observe the light reflected by the first reflector 32 and the second reflector 33, it indicates that the displacement of the clamping block 22 exceeds the predetermined value, that is, the binding and fixing effect of the main body 1 on the wire middle portion 41 and the wire terminal portion 42 is about to fail, and the staff is required to replace the main body 1 immediately to prevent a dangerous situation from occurring.

[0060] The limiting rod 24 also has end rods 242 extending outward from both ends of the middle rod 241, and an empty slot 243 is formed between the end rod 242 and the middle block 21. The function of the empty slot 243 is that when the cover plate 31 is squeezed by the clamping block 22 and falls off the main body 1, due to the existence of the empty slot 243, the free fall movement of the cover plate 31 will not be blocked by the limiting rod 24, ensuring that the cover plate 31 can smoothly fall off the main body 1 and fall to the ground, so that the first reflector 32 and the second reflector 33 can be completely exposed to the external environment; two force plates 34 are fixed on the side of the cover plate 31 away from the main body 1, and the end rod 242 can follow the clamping block 22 The end rod 242 moves together, so that the movement of the clamping block 22 can be transmitted to the force-bearing plate 34 by means of the end rod 242, so that it is convenient to drive the cover plate 31 to move through the force-bearing plate 34, and two clearance grooves 311 are provided on the cover plate 31; the end rod 242 extends to the inside of the clearance groove 311, and a gap 312 is left between the end of the end rod 242 and the inner wall of the clearance groove 311, that is, the end rod 242 does not contact the cover plate 31. This arrangement makes it convenient for the staff to install and fix the cover plate 31 to the main body 1, ensuring that the end rod 242 will not cause obstruction to the cover plate 31 during the installation process; the end rod 242 is located between the force-bearing plate 34 and the main body 1.

[0061] A slide groove 35 is provided on the side of the second shell 12, and a slider 36 corresponding to the slide groove 35 is fixed on the force-bearing plate 34. The slider 36 is slidably inserted in the slide groove 35 in an interference fit manner. The cover plate 31 is mainly fixedly connected to the main body 1 by the friction force between the slider 36 and the slide groove 35.

[0062] The clamping block 22 in the present invention can be used as a key to open the cover plate 31. Only when the displacement of the clamping block 22 exceeds a predetermined value, the cover plate 31 will fall off the main body 1, exposing the first reflector 32 and the second reflector 33 blocked by the cover plate 31, which is beneficial for the staff to check the main body 1 that is about to be damaged, and uses the mechanical structure to achieve a relatively intelligent warning effect, thereby improving the overall safety.

[0063] A line tightening method, based on the above-mentioned intelligent line tightening device, comprises the following steps:

[0064] S1, remove the second housing 12 and the intermediate component 2, and allow the wire terminal 42 to pass through the U-shaped rib 14;

[0065] S2, using the middle component 2 to push down the wire terminal portion 42, so that the wire terminal portion 42 is pressed onto the first housing 11 by the clamping block 22 located at the bottom of the middle component 2, and then the wire is bent so that the wire middle portion 41 and the wire terminal portion 42 are roughly parallel, and the wire middle portion 41 contacts the clamping block 22 located at the top of the middle component 2;

[0066] S3, using the second housing 12 to press the wire middle portion 41 onto the clamping block 22 located at the top of the middle component 2;

[0067] S4. Tighten the nut onto the U-shaped rib 14 and install the insulating cover;

[0068] S5, fixing the first reflector 32 and the second reflector 33 to predetermined positions of the main body 1;

[0069] S6, aligning and inserting the slider 36 into the slide groove 35, and completing the installation of the cover plate 31.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
