Description

Technical Field

[0001] The present invention relates to the technical field of wire tighteners, and particularly to an intelligent wire tightener and a wire tightening method thereof. Background Art

[0002] The terminal of a wire tightener is an important tool for tightening and fixing electric wires and cables during the construction of power lines. It is usually designed for the end of a power line or a position that requires special fixation to ensure that the electric wires and cables remain stable under the tightened state and prevent loosening or falling off due to external forces.

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

[0004] For example, the Chinese patent document with the publication number CN210927024U discloses a terminal wire tightener, which includes: a first wire tightening component and a second wire tightening component, and the second wire tightening component is clamped on the first wire tightening component; the first wire tightening component includes a first wire tightening piece and a first wire tightening outer shell, and the first wire tightening outer shell is sleeved on the first wire tightening piece; wherein, the first wire tightening piece, the first wire tightening outer shell and the second wire tightening component jointly form a wire tightening area. By the combined use of the first wire tightening component and the second wire tightening component, the terminal cable is placed in the wire tightening area composed of the first wire tightening piece, the first wire tightening outer shell and the second wire tightening component for fixation, which not only solves the problem of high working intensity of the traditional bundling method, reduces the operation fatigue of the manual labor, but also improves the work efficiency.

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

[0006] Since the terminal of a wire tightener is usually used to tightly bind and fix the terminal of an electric wire or cable, after binding and fixing the terminal of the electric wire or cable, since the middle part of the electric wire or cable is in a suspended state, its own gravity will generate a pulling force on the wire tightener. Generally, since the frictional force between the wire tightener and the electric wire or cable is greater than the above-mentioned pulling force, the wire tightener and the electric wire or cable will not slide relative to each other, and the wire tightener maintains the binding and fixing effect on the electric wire or cable. However, over time, the wire tightener itself may age or corrode, etc. At this time, the frictional force between the wire tightener and the electric wire or cable may gradually decrease. Once the frictional force between the wire tightener and the electric wire or cable decreases to be less than the above-mentioned pulling force, the wire tightener and the electric wire or cable will slide relative to each other under the action of this pulling force, resulting in the wire tightener losing the binding and fixing effect on the terminal of the electric wire or cable, and the terminal of the electric wire or cable will slip off the wire tightener, which is likely to cause safety accidents. Summary of the Invention

[0007] The object of the present invention is to provide an intelligent wire tightener and its wire tightening method to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An intelligent wire tightener includes a main body. An intermediate component is arranged in the wire tightening area between the first outer shell and the second outer shell of the main body. The upper and lower ends of the intermediate component respectively press the middle part of the wire and the terminal part of the wire against the first outer shell and the second outer shell to fix the middle part of the wire and the terminal part of the wire.

[0010] The intermediate component is slidably connected to the U-shaped rib of the main body. It includes an intermediate block, clamping blocks respectively arranged at the upper and lower ends of the intermediate block, and an inclined plate arranged inside the intermediate block and between the two clamping blocks. Among them, a vertically penetrating communication chamber is formed inside the intermediate block. The inclined plate is arranged inside the communication chamber, and a horizontally arranged intermediate shaft is fixed inside the communication chamber. The inclined plate can rotate around the axis of the intermediate shaft, and the upper and lower ends of the inclined plate are respectively hinged to the two clamping blocks.

[0011] Preferably, grooves recessed towards the middle of the intermediate block are formed on the upper and lower end faces of the intermediate block. The two ends of the communication chamber are respectively communicated with the two grooves, and the two clamping blocks are respectively arranged inside the two grooves in an interference fit manner.

[0012] Preferably, the wire tightener further includes a warning component for emitting an alarm when the clamping block moves relative to the intermediate block.

[0013] The warning component includes second reflective members fixed on the front and rear end faces of the first outer shell, first reflective members fixed on the front and rear end faces of the second outer shell, and cover plates arranged at the front and rear ends of the main body and used to respectively cover and block the corresponding first reflective members and second reflective members.

[0014] The cover plate is connected to the main body, and when the clamping block moves a predetermined distance relative to the intermediate block, the cover plate is squeezed by the clamping block and falls off from the main body.

[0015] Preferably, a limiting rod is fixedly connected to the front end of one of the clamping blocks and the rear end of the other clamping block. 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 has end rod bodies extending outward from both ends of the middle rod body, and an empty groove is formed between the end rod bodies and the middle block;

[0017] Two stress plates are fixed on the side of the cover plate away from the main body, and two relief grooves are formed in the cover plate;

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

[0019] The end rod body is located between the stress plate and the main body.

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

[0021] Preferably, arc-shaped grooves are formed on both sides of the two clamping blocks where they are separated from each other. A receiving groove is formed on the inner arc surface of the arc-shaped groove. The top of the inclined plate is hinged to a second fixing block through an end shaft. The second fixing block is fixedly connected to the clamping block through a bolt. The head of the bolt is located inside the receiving groove, and a sealing plate is hermetically arranged inside the receiving groove.

[0022] Preferably, first fixing blocks are fixed at both ends of the intermediate shaft, and the first fixing blocks are fixedly installed inside the communication chamber.

[0023] Preferably, connection blocks are fixed on both sides of the middle block, and the U-shaped rib passes through a circular hole formed in the connection block.

[0024] A wire tightening method, the wire tightening method is based on the above intelligent wire tightener, and includes the following steps:

[0025] S1. Remove the second outer shell and the intermediate component, and pass the terminal part of the wire through the U-shaped rib;

[0026] S2. Use the intermediate component to push down the terminal part of the wire, so that the terminal part of the wire is pressed against the first outer shell by the clamping block located at the bottom of the intermediate component. Then bend the wire so that the middle part of the wire and the terminal part of the wire are substantially parallel, and make the middle part of the wire contact the clamping block located at the top of the intermediate component;

[0027] S3. Use the second outer shell to press the middle part of the wire against the clamping block located at the top of the intermediate component;

[0028] S4. Tighten the nut on the U-shaped rib and install the insulating cover;

[0029] S5. Fix the first reflector and the second reflector at the predetermined positions of the main body;

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

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. In the present invention, an intermediate member is provided in the wire tightening area, and the intermediate member is used 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 two clamping blocks. After the main body cooperates with the intermediate member 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 at the top of the intermediate member 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 shaft, and the upper and lower ends of the inclined plate are respectively hinged to the two clamping blocks, once the clamping block at the top of the intermediate member moves forward or the clamping block at the bottom of the intermediate member moves backward, it will drive the top of the inclined plate to flip forward, increasing the distance between the two clamping blocks, that is, increasing the extrusion force of the two clamping blocks on the middle part of the wire and the terminal part of the wire. In this structure, even when the main body ages and the second housing becomes loose, it can ensure that the middle part of the wire and the terminal part of the wire remain tightly 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, thus ensuring safety.

[0033] 2. The cover plate of the present invention is used to block the first reflector and the second reflector. When the displacement of the clamping block does not exceed the predetermined value, both the first reflector and the second reflector will be covered and blocked by the cover plate. At this time, since the first reflector and the second reflector are covered and blocked by the cover plate, they will not generate reflection. However, once the displacement of the clamping block exceeds the predetermined value, the cover plate will be squeezed by the clamping block and fall off from 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 tightening and fixing effect of the main body on the middle part of the wire and the terminal part of the wire is about to fail, and the staff needs to replace the main body in time to prevent dangerous situations from occurring.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figures 1-12, the present invention provides a technical solution:

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

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

[0051] In the above solution, by arranging the intermediate member 2 in the wire tightening area 13 and using the intermediate member 2 to support between the middle part 41 of the wire and the terminal part 42 of the wire, the middle part 41 of the wire and the terminal part 42 of the wire are respectively in contact with the two clamping blocks 22. After the main body 1 cooperates with the intermediate member 2 to clamp the middle part 41 of the wire and the terminal part 42 of the wire, the middle part 41 of the wire will cause the clamping block 22 at the top of the intermediate member 2 to have a tendency to move forward due to its own gravity. However, since the present invention also provides 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 intermediate member 2 moves forward or the clamping block 22 at the bottom of the intermediate member 2 moves backward, it will drive the top of the inclined plate 23 to flip forward, increasing the distance between the two clamping blocks 22, that is, increasing the extrusion force of the two clamping blocks 22 on the middle part 41 of the wire and the terminal part 42 of the wire. In this structure, even when the main body 1 ages or other situations cause the second housing 12 to become loose, it can ensure that the middle part 41 of the wire and the terminal part 42 of the wire remain tightly fixed by the main body 1, and the middle part 41 of the wire and the terminal part 42 of the wire will not slip off the main body 1, and the safety is guaranteed.

[0052] Further, concave grooves 211 that are recessed toward the middle of the intermediate block 21 are formed on the upper and lower end surfaces of the intermediate block 21. Both ends of the communication chamber 212 are respectively communicated with the two concave grooves 211. The two clamping blocks 22 are respectively arranged inside the two concave grooves 211 in an interference fit manner; specifically, the purpose of arranging the clamping blocks 22 inside the two concave grooves 211 in an interference fit manner is to fix the position of the clamping blocks 22 by using the frictional force between the clamping blocks 22 and the inner wall surfaces of the concave grooves 211, so that the clamping blocks 22 can remain inside the concave grooves 211 in the state where the clamping blocks 22 do not clamp the cable.

[0053] Limit rods 24 are fixedly connected to the front end of one of the clamping blocks 22 (that is, the clamping block 22 at the top of the intermediate member 2) and the rear end of the other clamping block 22 (that is, the clamping block 22 at the bottom of the intermediate member 2). The limit rods 24 have intermediate rod bodies 241. Both ends of the intermediate rod bodies 241 are in contact with the intermediate block 21. Since both ends of the intermediate rod bodies 241 are in contact with the intermediate block 21, as Figure 6 shown, therefore, the intermediate rod bodies 241 have the function of limiting the position of the clamping blocks 22. For example, the clamping block 22 at the top of the intermediate member 2 cannot move backward under the limitation of the intermediate rod body 241, and the clamping block 22 at the bottom of the intermediate member 2 cannot move forward under the limitation of the intermediate rod body 241.

[0054] Both sides of the two clamping blocks 22 that are separated are provided with arc grooves 221. The setting of the arc grooves 221 is beneficial to increasing the contact area between the clamping blocks 22 and the middle part 41 of the wire and the terminal part 42 of the wire. A storage groove 222 is provided on the inner arc surface of the arc groove 221. The setting of the storage groove 222 increases the roughness of the inner arc surface of the arc groove 221, thereby increasing the friction between the clamping blocks 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 fixing block 234 through an end shaft 233. The second fixing block 234 is fixedly connected with the clamping block 22 through a bolt 235. The head of the bolt 235 is located inside the storage groove 222, and a sealing plate 223 is hermetically arranged inside the storage groove 222. The sealing plate 223 is used to prevent rainwater and the like from entering the inside of the storage groove 222, thereby being beneficial to avoiding the oxidation and rust of the bolt 235 by rainwater.

[0055] Both ends of the intermediate shaft 231 are fixed with first fixing blocks 232, and the first fixing blocks 232 are fixedly installed inside the communication chamber 212.

[0056] Both sides of the intermediate block 21 are fixed with connecting blocks 25. The U-shaped rib 14 passes through the round holes 251 provided on the connecting blocks 25, so that the intermediate block 21 can slide on the U-shaped rib 14.

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

[0058] The wire tightener further includes a warning component 3, which is used to issue an alarm when the clamping block 22 moves relative to the intermediate block 21. Since the movement of the clamping block 22 relative to the intermediate block 21 necessarily means that the middle part 41 of the wire and the terminal part 42 of the wire are displaced after being clamped, therefore, the warning component 3 is used to monitor whether the middle part 41 of the wire and the terminal part 42 of the wire are displaced after being clamped.

[0059] Specifically, the warning component 3 includes a second reflective member 33 fixed to the front and rear end faces of the first housing 11, a first reflective member 32 fixed to the front and rear end faces of the second housing 12, and cover plates 31 disposed at the front and rear ends of the main body 1 and used to respectively cover and block the corresponding first reflective member 32 and second reflective member 33. Among them, the first reflective member 32 and the second reflective member 33 can adopt reflective films and are then fixed to the main body 1 by pasting; the cover plates 31 are connected to the main body 1, and when the clamping block 22 moves a predetermined distance relative to the intermediate block 21, the cover plates 31 are squeezed by the clamping block 22 and fall off from the main body 1; the cover plates 31 are used to block the first reflective member 32 and the second reflective member 33, so that when the displacement of the clamping block 22 does not exceed the predetermined value, both the first reflective member 32 and the second reflective member 33 will be covered and blocked by the cover plates 31. At this time, since the first reflective member 32 and the second reflective member 33 are covered and blocked by the cover plates 31, no reflection will occur. However, once the displacement of the clamping block 22 exceeds the predetermined value, the cover plates 31 will be squeezed by the clamping block 22 and fall off from the main body 1. At this time, the first reflective member 32 and the second reflective member 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 reflective member 32 and the second reflective member 33, it indicates that the displacement of the clamping block 22 exceeds the predetermined value, that is, the tightening and fixing effect of the main body 1 on the middle part 41 and the terminal part 42 of the wire is about to fail, and the staff needs to replace the main body 1 immediately to prevent dangerous situations from occurring.

[0060] The limiting rod 24 also has end rod bodies 242 extending outward from both ends of the middle rod body 241. An empty groove 243 is formed between the end rod bodies 242 and the intermediate block 21. The function of the empty groove 243 is that when the cover plate 31 is squeezed by the clamping block 22 and falls off from the main body 1, due to the existence of the empty groove 243, the free-fall motion of the cover plate 31 will not be blocked by the limiting rod 24, ensuring that the cover plate 31 can smoothly fall off from the main body 1 and fall to the ground, so that the first reflective member 32 and the second reflective member 33 can be completely exposed to the external environment; two stress plates 34 are fixed to the side surface of the cover plate 31 away from the main body 1. The end rod bodies 242 can move together with the clamping block 22, so that the movement of the clamping block 22 can be transmitted to the stress plates 34 through the end rod bodies 242, thereby facilitating the driving of the cover plate 31 to move through the stress plates 34, and two relief grooves 311 are formed on the cover plate 31; the end rod bodies 242 extend into the relief grooves 311, and a gap 312 is left between the ends of the end rod bodies 242 and the inner walls of the relief grooves 311, that is, the end rod bodies 242 do not contact the cover plate 31. Such a setting facilitates the staff to install and fix the cover plate 31 to the main body 1, ensuring that the end rod bodies 242 will not hinder the cover plate 31 during the installation process; the end rod bodies 242 are located between the stress plates 34 and the main body 1.

[0061] A chute 35 is provided on the side of the second housing 12. A slider 36 corresponding to the chute 35 is fixed on the force-bearing plate 34. The slider 36 is slidably inserted into the chute 35 in an interference fit manner. The cover plate 31 is mainly fixedly connected to the main body 1 through the frictional force between the slider 36 and the chute 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 from the main body 1, exposing the first reflector 32 and the second reflector 33 blocked by the cover plate 31, which is conducive to the inspection of the main body 1 that is about to be damaged by the staff, realizing a relatively intelligent warning function by using a mechanical structure, and improving the overall safety.

[0063] A wire tightening method, which is based on the above intelligent wire tightener, includes the following steps:

[0064] S1. Remove the second housing 12 and the intermediate member 2, and pass the wire terminal portion 42 through the U-shaped rib 14;

[0065] S2. Use the intermediate member 2 to push down the wire terminal portion 42, so that the wire terminal portion 42 is pressed against the first housing 11 by the clamping block 22 located at the bottom of the intermediate member 2, and then bend the wire so that the middle portion 41 of the wire and the wire terminal portion 42 are substantially parallel, and make the middle portion 41 of the wire contact the clamping block 22 located at the top of the intermediate member 2;

[0066] S3. Use the second housing 12 to press the middle portion 41 of the wire against the clamping block 22 located at the top of the intermediate member 2;

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

[0068] S5. Fix the first reflector 32 and the second reflector 33 at the predetermined positions of the main body 1;

[0069] S6. Align the slider 36 and insert it into the chute 35 to complete the installation of the cover plate 31.

[0070] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
