Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric power engineering, in particular to a wire clamp for electric power engineering. Background Art
[0002] In the power engineering industry, wire clamps are an important part of line connection. The stable connection of cables is the basis for ensuring the stable operation of power engineering. Wire clamps are iron or aluminum metal accessories that can be fixed on the wires. Most of them need to withstand large tensile forces during operation. Wire clamps are mainly divided into: equipment wire clamps, fuse clamps, wire holding clamps, terminal wire clamps, piercing grounding wire clamps, tightening wire clamps, insulation piercing wire clamps, double-headed wire clamps, lead-in wire clamps, etc. Among them, tension clamps are a commonly used device for fixing wires in power lines. This type of wire clamp uses bolts and pressure blocks to fix the wires by using the tightening force of the bolts and the friction generated by the wavy structure of the pressure block. Bolt-type tension clamps have been widely used in power line construction due to their advantages such as easy installation and reusability.
[0003] During long-term operation, due to factors such as wind, temperature changes or vibration, the pulling force of the wire on the wire clamp becomes larger. Under long-term action, the bolts clamping the wire may gradually loosen, affecting the fastening effect of the wire clamp. At the same time, the long-term force of the clamping block on the wire may cause wear to the wire, and wear will reduce the strength and toughness of the wire. Especially under the condition of long-term wear, the wire is more likely to break or fall off at the worn part. In the prior art, when the wire breaks, the method of locking and limiting the wire is too single. During the subsequent maintenance process, the locking and limiting function of the wire is easily caused by accidental touch and other factors, resulting in the wire directly detaching from the wire clamp. The subsequent re-installation requires the wire to be reinserted into the wire clamp, and the convenience of the overall maintenance process is poor. Therefore, the existing wire clamp device is still inconvenient in actual use, and there is room for improvement in improving the convenience of maintenance. Summary of the invention
[0004] The purpose of the present invention is to solve the problem of poor portability of the overall maintenance process in the prior art, and to propose a wire clamp for power engineering.

[0006] Furthermore, the buffer mechanism includes a first limiting rod, and the outer wall of the first limiting rod is slidably connected to a tooth plate, the end of the tooth plate away from the first limiting rod is fixedly connected to a push plate, the end of the push plate away from the tooth plate is fixedly connected to a first spring, the side wall of the tooth plate is provided with a second tooth groove, and the inner wall of the second tooth groove is matched and meshed with a gear, and the center of the gear is rotatably connected to a fixed rod.
[0007] Furthermore, one end of the first limiting rod away from the tooth plate is fixedly connected to the inner wall of the upper locking body, one end of the first spring away from the abutment plate is fixedly connected to the inner wall of the upper locking body, and one end of the fixing rod away from the gear is fixedly connected to the inner wall of the upper locking body.
[0008] Furthermore, a first tooth groove is formed on the side wall of the lower clamping block, and the inner wall of the first tooth groove matches and meshes with the inner wall of the gear teeth of the gear.
[0009] Further, the self-locking mechanism includes a mounting frame, and the inner wall of the mounting frame is fixedly connected to a second limit rod, the side wall of the mounting frame is slidably connected with a push rod, and the outer wall of the push rod is fixedly connected to a fixing ring, the side wall of the fixing ring is fixedly connected to a second spring, and the end of the second spring away from the fixing ring is fixedly connected to the side wall of the mounting frame, the outer wall of the push rod is provided with a first slot, and the inner wall of the first slot is rotatably connected to a rotating plate, the end of the rotating plate away from the first slot is fixedly connected to a first sleeve, and the inner wall of the first sleeve is slidably connected to the second sleeve, the inner wall of the second sleeve is slidably connected to a third sleeve, and the inner wall of the first slot is provided with a second slot.
[0010] Further, the end of the third sleeve away from the second sleeve is rotatably connected to the inner wall of the second slot, the end of the second sleeve away from the third sleeve is fixedly connected to a third spring, and the end of the third spring away from the second sleeve is fixedly connected to the inner wall of the first sleeve, the end of the third sleeve close to the second sleeve is fixedly connected to a fourth spring, and the end of the fourth spring away from the third sleeve is fixedly connected to the inner wall of the second sleeve, the side wall of the mounting frame is slidably connected to a sliding block, and one end of the sliding block is fixedly connected to a self-locking clamping block, the side wall of the sliding block is provided with an oblique groove, and the inner wall of the oblique groove is provided with a through groove.
[0011] Furthermore, the side wall of the mounting frame is fixedly connected to the outer wall of the upper locking body, the inner wall of the self-locking clamp corresponds to the outer wall of the wire, the outer wall of the second limit rod passes through and is slidably connected to the interior of the self-locking clamp, and the end of the support rod slides in contact with the inner wall of the inclined groove.

[0013] Furthermore, a fastening block is fixedly connected to the outer wall of the upper locking body, and a wire pulling rod is fixedly connected to the inner wall of the fastening block.
[0014] Compared with the prior art, the above solution has the following beneficial effects: 1. When the wire generates unstable tension, the lower clamping block slides and drives the gear to rotate, and then the tooth plate drives the abutment plate to move, so that the first spring is stretched. When the tension of the wire becomes smaller, the force of the first spring being stretched is greater than the tension generated by the wire, so that the lower clamping block is reset and slid through the tooth plate transmission, so that when the tension of the wire is unstable, the strong tension suddenly generated by the wire can be partially buffered. By buffering the tension, the damage and failure rate of the wire clamp caused by excessive tension can be reduced, thereby reducing the workload and maintenance costs of maintenance personnel.
[0015] 2. When the tension generated by the wire is too large and breaks, the first spring is used to reset and hit the support rod, so that the end of the support rod slides along the inclined groove to the inner wall of the through groove, thereby limiting the sliding block. The self-locking clamping blocks on both sides slide relative to each other, so that the wire between them can be clamped. When the wire breaks at the clamping point of the lower clamping block, the wire can be tightened and limited instantly to prevent the wire from falling off the wire clamp and accidentally falling onto the ground or water, thereby causing serious power accidents and possibly causing damage to the surrounding natural environment.
[0016] 3. When it is necessary to continue to inspect and repair the wire, the rotating plate on either side can be pressed to make the fixed ring lose the limit of the sliding hole. In this state, the maintenance personnel manually maintain the elastic state of overcoming the third spring, the fourth spring and the second spring. In this state, the two still maintain the locking state of the wire. At this time, the maintenance personnel can operate according to actual work needs, that is, if other required operations occur, the pressure on the rotating plate can be released at this time, and the locking limit of the wire can still be maintained. Compared with the traditional method of partial one-button reset, this method provides a certain operation buffer period for the maintenance personnel and is more suitable for actual maintenance conditions. During this process, the maintenance personnel can press either side with one hand and operate the wire with the other hand to achieve the maintenance purpose. Through the symmetrical structural setting, on the one hand, the locking strength is improved, and on the other hand, the convenience of maintenance is further improved.

In addition, the terms "first" and "second" are only used to distinguish an entity or operation from another entity or operation, and do not require or imply any actual relationship, order or relative importance between these entities or operations.
[0021] For example, see Figure 1-3 , a wire clamp for electric power engineering, comprising a lower locking body 1, the top of the lower locking body 1 is connected to an upper locking body 2 by bolts, and a limiting groove 3 is provided on the inner wall of the upper locking body 2, a lower clamping block 4 is slidably connected to the inner wall of the limiting groove 3, and an upper clamping block 5 is connected to the top of the lower clamping block 4 by bolts, a conductor 6 is fixedly installed between the lower clamping block 4 and the upper clamping block 5, a fastening block 11 is fixedly connected to the outer wall of the upper locking body 2, and a wire pulling rod 12 is fixedly connected to the inner wall of the fastening block 11; When installing the wire clamp, first install the wire 6 into the top installation groove of the lower clamping block 4 according to the routing direction of the wire 6, then align the bottom of the upper clamping block 5 with the top of the lower clamping block 4 and fit them together, and then lock and fix the lower clamping block 4 and the upper clamping block 5 by bolts, so that the wire 6 can be clamped and fixed by the installation of the lower clamping block 4 and the upper clamping block 5, then align the bottom of the lower locking body 1 with the top of the upper locking body 2 and fit them together, and then install the lower locking body 1 and the upper locking body 2 together by bolts, and then install it to the installation area on the pole through the wire pull rod 12 to complete the installation of the wire clamp.
[0022] For example 2, please refer to Figure 2-3On the basis of the first embodiment, in this embodiment, a buffer mechanism 7 is provided on the inner wall of the upper locking body 2. When the tension generated by the wire 6 is unstable, the tension generated by the wire 6 can be buffered during use. The buffer mechanism 7 includes a first limiting rod 701, and the outer wall of the first limiting rod 701 is slidably connected with a tooth plate 702, and the end of the tooth plate 702 away from the first limiting rod 701 is fixedly connected with a plate 703, and the end of the plate 703 away from the tooth plate 702 is fixedly connected with a first elastic member. Spring 704, the side wall of the tooth plate 702 is provided with a second tooth groove 705, and the inner wall of the second tooth groove 705 is matched and meshed with a gear 706, the center of the gear 706 is rotatably connected to a fixing rod 707, the end of the first limiting rod 701 away from the tooth plate 702 is fixedly connected to the inner wall of the upper locking body 2, the end of the first spring 704 away from the abutment plate 703 is fixedly connected to the inner wall of the upper locking body 2, and the end of the fixing rod 707 away from the gear 706 is fixedly connected to the inner wall of the upper locking body 2; During long-term operation, when the wire 6 is subjected to external forces such as strong winds and ice, a large pulling force will be generated, which can cause the connection between the wire 6 and the wire clamp to become more tense, increase instability during use and potential safety risks, and pose a potential threat to the stable operation of the power system. In order to ensure the safe and stable operation of the power system, when the wire 6 generates unstable pulling force, it will drive the lower clamping block 4 to slide along the inner wall of the limiting groove 3. The side wall of the lower clamping block 4 is provided with a first tooth groove 8, and the inner wall of the first tooth groove 8 matches and meshes with the inner wall of the gear teeth of the gear 706. Therefore, the lower clamping block 4 will drive the gear 706 to rotate during the sliding process, and at the same time, the gear 706 will drive the tooth plate 702 to move through the second tooth groove 705, so that the tooth plate 702 slides along the outer wall of the first limiting rod 701. By setting the first limit rod 701, the tooth plate 702 will not deviate during the sliding process. When the tooth plate 702 slides, it will drive the abutment plate 703 to move. At the same time, the abutment plate 703 will drive one end of the first spring 704 to move, so that the first spring 704 is stretched. Then the force generated by the stretching of the first spring 704 generates resistance to the sliding process of the tooth plate 702. When the tension of the wire 6 becomes smaller, the stretched force of the first spring 704 is greater than the tension generated by the wire 6. The lower clamping block 4 is reset and slid through the transmission of the tooth plate 702, so that when the tension of the wire 6 is unstable, a part of the strong tension suddenly generated by the wire 6 can be buffered. Therefore, by buffering the tension, the damage and failure rate of the wire clamp caused by excessive tension can be reduced, thereby reducing the workload and maintenance cost of the maintenance personnel.
[0023] For example 3, please refer to Figure 3-6On the basis of the second embodiment, in this embodiment, the outer wall of the upper locking body 2 is provided with a self-locking mechanism 9, so that when the wire 6 is broken, the wire 6 can be automatically locked and limited. The self-locking mechanism 9 includes a mounting frame 901, and the inner wall of the mounting frame 901 is fixedly connected with a second limiting rod 902, and the side wall of the mounting frame 901 is slidably connected with a push rod 903, and the outer wall of the push rod 903 is fixedly connected with a fixing ring 904, and the side wall of the fixing ring 904 is fixedly connected with a second spring 905, and the end of the second spring 905 away from the fixing ring 904 is fixedly connected to the side wall of the mounting frame 901, and the outer wall of the push rod 903 is provided with a first slot 906, and the inner wall of the first slot 906 is rotatably connected with a rotating plate 907, and the end of the rotating plate 907 away from the first slot 906 is fixedly connected with a first sleeve 908, and the inner wall of the first sleeve 908 is slidably connected with a second sleeve 909, and the second sleeve The inner wall of 909 is slidably connected with a third sleeve 910, the inner wall of the first slot 906 is provided with a second slot 911, the end of the third sleeve 910 away from the second sleeve 909 is rotatably connected to the inner wall of the second slot 911, the end of the second sleeve 909 away from the third sleeve 910 is fixedly connected with a third spring 912, and the end of the third spring 912 away from the second sleeve 909 is fixedly connected to the inner wall of the first sleeve 908, the end of the third sleeve 910 close to the second sleeve 909 is fixedly connected with a fourth spring 913, and the end of the fourth spring 913 away from the third sleeve 910 is fixedly connected to the inner wall of the second sleeve 909, the side wall of the mounting frame 901 is slidably connected with a sliding block 914, and one end of the sliding block 914 is fixedly connected with a self-locking clamping block 915, the side wall of the sliding block 914 is provided with an oblique groove 916, and the inner wall of the oblique groove 916 is penetrated with a through groove 917; During long-term use, the bolts used to clamp the wire 6 will gradually loosen due to continuous mechanical stress and environmental factors, which may affect the tightening effect of the wire clamp. At the same time, clamping the wire 6 for a long time will produce continuous contact pressure, which may cause significant wear on the surface of the wire 6, or cause the wire 6 to break or fall off when the tension is too large. When the contact position between the wire 6 and the lower clamping block 4 breaks, the lower clamping block 4 is no longer affected by the tension of the wire 6, so that the stretched first spring 704 is no longer subjected to tension. A sliding hole 10 is formed through the outer wall of the upper locking body 2, and the outer wall of the push rod 903 is slidably connected to the inner wall of the sliding hole 10. The side wall of the push plate 703 corresponds to the end of the push rod 903, so that The push plate 703 quickly hits the end of the push rod 903, causing the push rod 903 to slide outward along the outer wall of the sliding hole 10. During the process, the push rod 903 will compress the second spring 905 through the fixing ring 904. When the push rod 903 slides to a certain position, the multiple rotating plates 907 will contact the inner wall of the sliding hole 10 and be squeezed by it, and then one end of the multiple rotating plates 907 will rotate, and then the other end will shrink toward the inside of the second slot 911. During the process, the first sleeve 908 will slide along the outer wall of the second sleeve 909, and the second sleeve 909 will slide along the outer wall of the third sleeve 910. At the same time, the third spring 912 and the fourth spring 913 will be compressed. Then, when the end of the rotating plate 907 rotates to the second slot When the first spring 704 is reset, the plate 703 is separated from the contact with the push rod 903, and the second spring 905 is reset by elastic force to squeeze the fixing ring 904. At this time, the plurality of rotating plates 907 are stuck on the outer wall of the upper locking body 2, which stops the push rod 903 from sliding along the inner wall of the sliding hole 10. During the movement process, the side wall of the mounting frame 901 is fixedly connected to the outer wall of the upper locking body 2, the inner wall of the self-locking clamp 915 corresponds to the outer wall of the wire 6, the outer wall of the second limiting rod 902 passes through and is slidably connected to the inside of the self-locking clamp 915, and the end of the push rod 903 slides in contact with the inner wall of the inclined groove 916. During the process of the push rod 903 sliding outward, its end will slide along the inner wall of the inclined groove 916, so that the sliding block 914 will slide in contact with the mounting frame 901, and then the end of the push rod 903 will slide into the inside of the through groove 917, thereby completing the limitation of the sliding block 914. During the process of the inclined groove 916 being squeezed to cause the sliding block 914 to slide, the sliding block 914 will drive the self-locking clamp 915 to slide along the inner wall of the mounting frame 901.At the same time, the second limiting rod 902 penetrates the interior of the self-locking clamp 915, which can ensure that the self-locking clamp 915 is more stable during the sliding process. The self-locking clamps 915 on both sides slide relative to each other to clamp the wire 6 therebetween. The inner clamping surface of the self-locking clamp 915 is provided with thorn-shaped hard objects and high-strength, high-wear-resistant materials that increase friction, so that when the wire 6 breaks at the clamping position of the lower clamping block 4, the wire 6 can be tightened and limited instantly, so as to prevent the wire 6 from falling off the wire clamp and accidentally falling onto the ground or water, thereby causing serious power accidents and possibly damaging the surrounding natural environment. By adopting this device, when the wire 6 breaks, the fixing ring 904 will be stuck on the outside of the sliding hole 10, so that the wire clamp is in a locked state for the wire 6. At this time, if the maintenance personnel need to perform maintenance operations on the wire 6, they can press the rotating plate 907 on either side, so that the fixing ring 904 loses the limit of the sliding hole 10. In this state, the maintenance personnel manually maintain the elastic state of overcoming the third spring 912, the fourth spring 913 and the second spring 905. In this state, the two 915 still maintain the locking state of the wire 6. At this time, the maintenance personnel can operate according to actual work needs, that is, if other required operations occur, the pressing of the rotating plate 907 is released at this time, and the locking limit of the wire 6 can still be maintained. Compared with the traditional method of partial one-button reset, this method provides a certain operation buffer period for maintenance personnel, which is more suitable for actual maintenance conditions. At the same time, by adopting this method, the maintenance personnel can press 907 on either side with one hand and operate the wire 6 with the other hand to achieve the maintenance purpose. Through the symmetrical structural setting, on the one hand, the locking strength is improved, and on the other hand, the convenience of maintenance is further improved.
[0024] The working principle of the present invention is: when the wire clamp is used, when the wire 6 is subjected to external forces such as strong winds and ice, and thus the wire 6 generates unstable tension, it will drive the lower clamping block 4 to slide along the inner wall of the limiting groove 3, and the lower clamping block 4 will drive the gear 706 to rotate during the sliding process, and at the same time, the gear 706 will drive the tooth plate 702 to move through the second tooth groove 705, so that the tooth plate 702 slides along the outer wall of the first limiting rod 701. By setting the first limiting rod 701, the tooth plate 702 will not deviate during the sliding process, and when the tooth plate 702 slides, it will drive the abutment plate 703 to move. The first spring 704 is moved, and the abutment plate 703 drives one end of the first spring 704 to move, so that the first spring 704 is stretched, and then the force generated by the stretching of the first spring 704 generates resistance to the sliding process of the tooth plate 702. When the tension of the wire 6 becomes smaller, the force of the stretching of the first spring 704 is greater than the tension generated by the wire 6, so that the lower clamping block 4 is reset and slid through the transmission of the tooth plate 702, so that when the tension of the wire 6 is unstable, the strong tension suddenly generated by the wire 6 can be partially buffered, so that by buffering the tension, the damage and failure rate of the wire clamp caused by excessive tension can be reduced; During the long-term use of the wire clamp, the surface of the wire 6 may be significantly worn, or the wire 6 may be broken or fall off when the tension is too large. When the wire 6 breaks at the contact position with the lower clamping block 4, the lower clamping block 4 is no longer subjected to the tension of the wire 6, so that the stretched first spring 704 is no longer subjected to the tension, so that the abutment plate 703 quickly hits the end of the abutment rod 903, so that the abutment rod 903 slides outward along the outer wall of the slide hole 10. During the process, the abutment rod 903 compresses the second spring 905 through the fixing ring 904. When the abutment rod 903 slides to a certain position, then the multiple rotating plates 907 contact the inner wall of the slide hole 10 and are squeezed by it, and then the multiple rotating plates 907 are pressed. One end of the movable plate 907 rotates, and then the other end will shrink toward the inside of the second slot 911. During this process, the first sleeve 908 will slide along the outer wall of the second sleeve 909, and the second sleeve 909 will slide along the outer wall of the third sleeve 910. At the same time, the third spring 912 and the fourth spring 913 will be compressed. Then, when the end of the rotating plate 907 rotates to the inside of the second slot 911, the push rod 903 will drive the rotating plate 907 to slide along the inside of the sliding hole 10 away from the inside of the upper locking body 2. Then, when the rotating plate 907 is away from the inner wall of the sliding hole 10, the third spring 912 and the fourth spring 913 will reset, so that the distance between the first sleeve 908 and the third sleeve 910 reaches The maximum distance can make multiple rotating plates 907 rotate in the direction away from the second slot 911. Then, when the first spring 704 is reset, the push plate 703 will be out of contact with the push rod 903, and then the second spring 905 will perform elastic reset to squeeze the fixing ring 904. At this time, multiple rotating plates 907 will be stuck on the outer wall of the upper locking body 2, and the push rod 903 will stop sliding along the inside of the sliding hole 10. In the process of the push rod 903 sliding outward, its end will slide along the inner wall of the inclined groove 916, so that the sliding block 914 will slide against the mounting frame 901, and then the end of the push rod 903 will slide into the inside of the through groove 917, thereby completing the limitation of the sliding block 914. 6 is squeezed to make the sliding block 914 slide, the sliding block 914 will drive the self-locking clamp 915 to slide along the inner wall of the mounting frame 901, and at the same time, the second limiting rod 902 penetrates the interior of the self-locking clamp 915, which can ensure that the self-locking clamp 915 is more stable during the sliding process, and the self-locking clamps 915 on both sides slide relative to each other to clamp the wire 6 therebetween. The inner clamping surface of the self-locking clamp 915 is provided with thorn-shaped hard objects and high-strength and high-wear-resistant materials that increase friction, so that when the wire 6 breaks at the clamping position of the lower clamping block 4, the wire 6 can be tightened and limited instantly to prevent the wire 6 from falling off the wire clamp and accidentally falling onto the ground or water, thereby causing a serious power accident.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention.
