Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of strain clamp, in particular to a strain clamp capable of preventing abrasion. BACKGROUND

[0002] As an indispensable hardware for power transmission line, the core function of strain clamp is to stably connect the conductor or lightning conductor to the strain insulator string of non-straight tower, which not only bears the anchoring function but also takes the conductive task. In the ultra-high voltage power transmission line, the strain clamp and the compression technology of the connecting pipe are the cornerstone to ensure uninterrupted power transmission over long distances. However, with the rapid development of power grid and the continuous rise of voltage level, the power transmission line is increasingly dense, and the performance problems of a large number of strain clamps gradually become prominent after a long time of operation, which becomes a key factor threatening the safe and stable operation of the power grid. During the long-time operation of the strain clamp, the repeated movement and friction of the conductor will cause abrasion between the conductor and the clamping area, thereby reducing the clamping effect of the clamping area on the conductor, and in severe cases, the outer layer of the conductor will be damaged, and the conductor will be exposed to the risk of electric leakage and short circuit. SUMMARY

[0003] The purpose of the present application is to solve the problem of abrasion of the clamping area of the traditional strain clamp caused by the movement of the conductor, which causes damage to the outer layer of the conductor and leads to potential safety hazards such as electric leakage and short circuit, and to provide a strain clamp capable of preventing abrasion.

[0004] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A strain clamp capable of preventing abrasion, comprising an integrated lifting part and a clamping part, wherein the outer part of the clamping part is provided with a U-shaped lock, the lower end of the U-shaped lock is movably connected with a clamping block, and the clamping part is internally provided with a force relief assembly for reducing the abrasion degree of the conductor. The force relief assembly comprises an inner lining movably connected to the inside of the clamping part, and the two sides of the inner lining are fixedly connected with first sliding blocks, the two side inner walls of the clamping part are provided with first sliding grooves matched with the first sliding blocks, the upper end of the clamping block is fixedly connected with a second sliding block, and the lower end of the U-shaped lock is provided with a second sliding groove matched with the second sliding block, and the side edge of the clamping block is rounded.

[0005] Further description of the above-mentioned technical scheme: The first sliding groove extends upward from the middle to form an inverted T shape, an auxiliary installation assembly is arranged between the first sliding block and the first sliding groove, the auxiliary installation assembly comprises a telescopic block movably connected to the lower end of the first sliding block, and a spring is fixedly connected between the telescopic block and the first sliding block, and the inner lining is a U-shaped elastic piece.

[0006] Further description of the above-mentioned technical scheme: The spring has a spring force greater than the resistance of the first sliding block when sliding up and down inside the first sliding groove, and the first sliding block has a trapezoidal cross section.

[0007] As a further description of the above technical solution: The inner liner and the clamping block are provided with a anti-falling assembly, the anti-falling assembly comprises first clamping blocks fixedly connected to the bottom of the front and rear ends of the clamping block, the inner walls on both sides of the inner liner are fixedly connected with second clamping blocks, and the lower end of the second clamping block and the upper end of the first clamping block are fixedly connected with clamping hooks, and the inside of the first sliding groove is fixedly connected with a movable shaft penetrating the telescopic block.

[0008] As a further description of the above technical solution: The lower end of the first clamping block and the upper end of the second clamping block are rounded, and the first clamping block and the second clamping block are provided with a plurality of groups.

[0009] As a further description of the above technical solution: The inside of the clamping part is provided with a drainage assembly, the drainage assembly comprises a water-absorbing sponge movably connected to the inside of the first sliding groove, and the bottom of the first sliding groove is provided with a drainage hole penetrating to the bottom end of the clamping part, and the water-absorbing sponge is movably sleeved on the outside of the movable shaft.

[0010] As a further description of the above technical solution: The inner side wall of the clamping part is provided with a water guide groove, and the water guide groove is inclined downward along the direction of the first sliding groove and is communicated with the first sliding groove.

[0011] As a further description of the above technical solution: The lower end of the lifting part is fixedly connected with a hook, the lower end of the clamping part is fixedly connected with a connecting seat, the lower end of the U-shaped lock penetrates through the connecting seat, the outside of the U-shaped lock is threadedly connected with a nut at the lower end of the connecting seat, the joint of the lifting part and the clamping part movably penetrates a bolt, and the rear end of the bolt movably penetrates a lock pin.

[0012] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are: The provision of a force unloading component can reduce the possibility of wear when the wire swings. When the wire swings, due to the close contact between the wire and the lining, and the outer layer of the wire is made of rubber material with toughness, and the lining and the clamping part are in rigid contact, and the inner wall of the clamping part is provided with a first slide groove, the contact area between the clamping part and the lining is also smaller than the contact area between the wire and the lining. Therefore, the friction between the wire and the lining is greater than the friction between the lining and the clamping part, so that when the wire swings, under the action of the swinging pulling force, the lining slides in the first slide groove through the first slider and first undergoes relative displacement with the clamping part, until the first slider slides to the end of the first slide groove, and then a pulling force greater than the friction between the two is generated between the wire and the lining. Since the swing of the wire is generally instantaneous and repeated, it rarely moves in a long direction. A continuous pulling force is generated in one direction, so when the conductor fluctuates, wear occurs between the lining and the clamping part in most cases, thereby reducing the possibility of wear between the conductor and the lining. At the same time, when the conductor swings and force is applied to the clamping block, the clamping block will slide in an arc trajectory inside the second slide groove through the second slider, thereby converting the original horizontal friction into circumferential rolling friction. At the same time, as the clamping block rotates, the distance between the clamping block and the conductor will be reduced, so that the clamping effect of the clamping block is improved, and the possibility of loosening when the conductor swings is reduced. The side edges of the clamping block are chamfered, so that the clamping block is in arc surface contact with the conductor when rotating and squeezing, which further reduces the possibility of wear on the conductor compared to the right-angled edges of the traditional clamping block, and improves the protective effect of the conductor when the tension clamp is used.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0016] like Figures 1-8 As shown, the present invention provides an anti-wear and tension-resistant wire clamp: it includes an integrally formed supporting part 10 and a clamping part 11, the outside of the clamping part 11 is provided with a U-shaped lock 15, and the lower end of the U-shaped lock 15 is movably connected to a clamping block 16, the lower end of the supporting part 10 is fixedly connected to a hook 12, the lower end of the clamping part 11 is fixedly connected to a connecting seat 17, the lower end of the U-shaped lock 15 passes through the connecting seat 17, the outside of the U-shaped lock 15 is threadedly connected to a nut 18 at the lower end of the connecting seat 17, a bolt 13 movably passes through the junction of the supporting part 10 and the clamping part 11, and a lock pin 14 movably passes through the rear end of the bolt 13, and also includes a force unloading component 20 arranged inside the clamping part 11 for reducing the degree of wear of the wire.

[0017] The force unloading assembly 20 includes an inner lining 21 movably connected to the inside of the clamping part 11, and a first slider 22 is fixedly connected to both sides of the inner lining 21. The inner walls on both sides of the clamping part 11 are provided with a first slide groove 23 adapted to the first slider 22. The upper end of the clamping block 16 is fixedly connected to the second slider 24, and the lower end of the U-shaped lock 15 is provided with a second slide groove 25 matching the second slider 24. The side edges of the clamping block 16 are chamfered.

[0018] Specifically, first, the strain clamp is connected with the insulator by the hook 12 and the bolt 13, and the connection is ensured to be stable, then the bolt 13 is fixed by the locking pin 14, then the strain conductor is inserted into the strain clamp, and the lifting part 10 lifts the conductor and the conductor is wrapped by the clamping part 11, then the U-shaped lock 15 is inserted from above the clamping part 11 through the connecting seat 17 and is fixed by the nut 18, when the nut 18 is tightened, the U-shaped lock 15 will press the clamping block 16 downward, so that the clamping block 16 cooperates with the clamping part 11 to clamp and fix the conductor.

[0019] In use, the conductor is prone to swing due to factors such as air flow, and after the conductor swings, it will rub against the contact area of the clamping part 11 and the clamping block 16, thereby causing the outer skin of the conductor to be abraded. Therefore, the force relieving assembly 20 is arranged to reduce the abrasion possibility when the conductor swings. When the conductor swings, due to the close contact between the conductor and the inner lining 21, and the toughness of the rubber material of the outer layer of the conductor, the contact between the inner lining 21 and the clamping part 11 is rigid, and the first sliding groove 23 is arranged on the inner side wall of the clamping part 11, so that the contact area between the clamping part 11 and the inner lining 21 is smaller than the contact area between the conductor and the inner lining 21. Therefore, the friction between the conductor and the inner lining 21 is greater than the friction between the inner lining 21 and the clamping part 11, so that when the conductor swings, under the action of the swing pulling force, the inner lining 21 first relatively displaces with the clamping part 11 by the first sliding block 22 sliding in the first sliding groove 23, until the first sliding block 22 slides to the end of the first sliding groove 23, and then the pulling force greater than the friction between the conductor and the inner lining 21 is generated between the conductor and the inner lining 21. Since the swing of the conductor is generally instantaneous and repeated, it is rarely continuous in one direction for a long time. Therefore, when the conductor swings, the inner lining 21 and the clamping part 11 are abraded in most cases, thereby reducing the abrasion possibility between the conductor and the inner lining 21. When the conductor swings and exerts a force on the clamping block 16, the clamping block 16 will slide in an arc trajectory in the second sliding groove 25 by the second sliding block 24, thereby converting the original horizontal friction into circumferential rolling friction. At the same time, the distance between the clamping block 16 and the conductor is reduced by the rotation of the clamping block 16, so that the clamping effect of the clamping block 16 is improved, the loosening possibility of the conductor when the conductor swings is reduced, and the side edge of the clamping block 16 is rounded, so that the clamping block 16 is in arc surface contact with the conductor when it rotates and presses, thereby further reducing the abrasion possibility of the conductor compared with the straight edge of the traditional clamping block 16, and improving the protection effect of the strain clamp on the conductor in use.

[0020] As Figure 4 With Figure 6As shown, the first sliding groove 23 extends upward from the middle to form an inverted T shape, and an auxiliary mounting assembly 30 is arranged between the first sliding block 22 and the first sliding groove 23. The auxiliary mounting assembly 30 includes an expansion block 31 movably connected to the lower end of the first sliding block 22, and a spring 32 fixedly connected between the expansion block 31 and the first sliding block 22. The inner liner 21 is a U-shaped elastic member.

[0021] The elastic force of the spring 32 is greater than the resistance that the first sliding block 22 suffers when sliding up and down inside the first sliding groove 23. The cross section of the first sliding block 22 is in the shape of a trapezoid with a wide upper part and a narrow lower part.

[0022] Specifically, in order to improve the stability of the fixed conductor, the opening width of the clamping part 11 is generally smaller than the diameter of the conductor. During installation, the conductor is squeezed into the inside of the clamping part 11 by taking advantage of the deformation characteristics of the outer layer of the conductor, and then the conductor is fixed by the U-shaped lock 15 and the clamping block 16. This installation method increases the operational burden of the workers in installing the strain clamp and the conductor, and forcibly pressing the conductor into the inside of the clamping part 11 also easily causes wear and tear to the conductor.

[0023] Therefore, the U-shaped inner liner 21 with elasticity is adopted. In the initial state, the expansion block 31 is pushed out of the outside of the first sliding block 22 by the spring 32, causing the first sliding block 22 to slide upward along the first sliding groove 23, so that the upper region of the inner liner 21 moves out of the outside of the clamping part 11 along with the first sliding block 22. The region of the inner liner 21 that extends out of the clamping part 11 expands to a flared state because it is not constrained by the clamping part 11. Therefore, when installing the conductor, the conductor can be first clamped into the inside of the inner liner 21. Since the inner liner 21 is in a flared state, the conductor can be smoothly clamped into its inside. Then the conductor is clamped by the U-shaped lock 15 and the clamping block 16, and the conductor and the inner liner 21 are pushed downward synchronously. When the inner liner 21 moves downward, the trapezoidal structure of the first sliding block 22 will play a role, causing the first sliding block 22 to press the inner liner 21 in the direction of the conductor when sliding inside the first sliding groove 23, and then causing the inner liner 21 to tightly wrap around the conductor and be squeezed into the inside of the clamping part 11 along with the conductor. On the one hand, there is no need to manually squeeze the conductor into the clamping part 11 in advance, which saves installation steps and installation strength. On the other hand, the conductor is protected by the inner liner 21 during the process of entering the inside of the clamping part 11, which reduces the possibility of wear and tear of the conductor.

[0024] As shown in the drawings, Figures 6-8 A prevent falling assembly 40 is arranged between the inner liner 21 and the clamping block 16. The prevent falling assembly 40 includes first clamping blocks 41 fixedly connected to the bottom of the front and rear ends of the clamping block 16. The inner walls on both sides of the inner liner 21 are fixedly connected with second clamping blocks 42, and the lower end of the second clamping block 42 and the upper end of the first clamping block 41 are fixedly connected with clamping hooks 43. The inside of the first sliding groove 23 is fixedly connected with a movable shaft 44 that penetrates the expansion block 31.

[0025] As a further description of the above technical solutions: The lower end of the first clamping block 41 and the upper end of the second clamping block 42 are both chamfered, and the first clamping block 41 and the second clamping block 42 are both provided with multiple groups.

[0026] Specifically, due to the swing of the conductor caused by air flow and other factors, the U-shaped lock 15 and the nut 18 will be loosened under the action of the conductor swing, so that the clamping block 16 cannot continue to clamp the conductor, and the conductor is easy to fall off from the strain clamp. In order to avoid such events, self-locking and other methods are generally used to limit the loosening of the nut 18. However, in addition to the loosening of the nut 18 caused by vibration, the U-shaped lock 15 is exposed to the air for a long time and is easily eroded by rainwater, which can also cause the U-shaped lock 15 to break, thereby causing the clamping effect of the clamping block 16 on the conductor to fail. Therefore, the effect of preventing the conductor from falling off by only preventing the loosening of the nut 18 is very limited.

[0027] Therefore, when the clamping block 16 is extruded, it will move towards the inner liner 21. As the clamping block 16 approaches the inner liner 21, the first clamping block 41 on the clamping block 16 will contact the second clamping block 42 on the inner liner 21. Under the action of the chamfered contact surface, the first clamping block 41 and the second clamping block 42 are extruded after contact, so that the first clamping block 41 and the second clamping block 42 are mutually overlapped, and the clamping hooks 43 on the first clamping block 41 and the second clamping block 42 are firmly hooked with each other, thereby locking the clamping block 16 and the inner liner 21. When the nut 18 is loosened or the U-shaped lock 15 is broken, the inner liner 21 is not limited by the U-shaped lock 15 and will extend outside the clamping portion 11. At this time, the first sliding block 22 moves upward along the first sliding groove 23, and the telescopic block 31 extends outside the first sliding block 22. However, since the bottom of the telescopic block 31 is sleeved outside the movable shaft 44, and the movable shaft 44 is fixedly connected with the first sliding groove 23, the movement range of the first sliding block 22 is limited, so that the inner liner 21 cannot completely separate from the clamping portion 11. Only the inner liner 21 that has partially separated from the clamping portion 11 will expand to both sides under the elastic action. The more the inner liner 21 expands, the more the clamping hooks 43 on the second clamping block 42 pull the clamping hooks 43 on the first clamping block 41, thereby preventing the clamping block 16 from separating from the conductor, so as to avoid the conductor from separating from the strain clamp when the nut 18 is loosened or the U-shaped lock 15 is broken. It should be noted that in common telescopic structures, the telescopic portion is limited and cannot completely extend and separate from the main body portion. Therefore, the telescopic block 31 in the present application also cannot completely extend outside the first sliding block 22, so as to ensure the limitation of the inner liner 21 to prevent it from separating from the clamping portion 11.

[0028] As Figure 3 With Figure 4As shown, the inside of the clamping part 11 is provided with a drainage assembly 50, which includes a water-absorbing sponge 51 movably connected to the inside of the first sliding groove 23, and the bottom of the first sliding groove 23 is provided with a drainage hole 52 penetrating to the bottom end of the clamping part 11, and the water-absorbing sponge 51 movably sleeves the outside of the movable shaft 44.

[0029] Further description of the above technical solutions: The inner side wall of the clamping part 11 is provided with a water guide groove 53, which is inclined downward along the direction of the first sliding groove 23 and communicates with the first sliding groove 23.

[0030] Specifically, after rainfall, part of the rainwater will seep into the clamping part 11 and the conductor through the fine gap, especially in winter, when rainwater seeps in, as the temperature decreases, the water will expand after freezing, which will squeeze the clamping part 11 from the inside, causing the strain clamp to expand in the local area, thereby reducing the firmness of the strain clamp to the conductor, and also prone to breakage.

[0031] Therefore, when rainwater seeps into the clamping part 11, the rainwater will flow into the first sliding groove 23 through the water guide groove 53, and then be absorbed by the water-absorbing sponge 51, and then the first sliding block 22 will slide transversely in the first sliding groove 23 due to the swinging of the conductor, thereby extruding the water-absorbing sponge 51, and then the water absorbed by the water-absorbing sponge 51 will be squeezed out and discharged outside the strain clamp through the drainage hole 52, preventing the rainwater from condensing and expanding in the clamping part 11, and ensuring the service life of the strain clamp.

[0032] Working principle: first, the strain clamp is connected with the insulator by using the hook 12 and the bolt 13, and the connection is ensured to be stable, then the bolt 13 is fixed by using the locking pin 14, then the strain conductor is inserted into the strain clamp, and the lifting part 10 lifts the conductor, and the clamping part 11 wraps the conductor, then the U-shaped lock 15 is inserted into the connecting seat 17 from above the clamping part 11 and is tightly fixed by using the nut 18, when the nut 18 is tightened, the U-shaped lock 15 will extrude the clamping block 16, so that the clamping block 16 cooperates with the clamping part 11 to clamp and fix the conductor.

[0033] When the conductor swings during use, due to the close contact between the conductor and the inner liner 21, and the toughness of the rubber material of the outer layer of the conductor, and the rigid contact between the inner liner 21 and the clamping portion 11, and the first sliding groove 23 formed in the inner side wall of the clamping portion 11, the contact area between the clamping portion 11 and the inner liner 21 is smaller than the contact area between the conductor and the inner liner 21, so the friction between the conductor and the inner liner 21 is greater than the friction between the inner liner 21 and the clamping portion 11, so that when the conductor swings, under the action of the swing pulling force, the inner liner 21 first relatively displaces with the clamping portion 11 by the first sliding block 22 sliding in the first sliding groove 23, and only after the first sliding block 22 slides to the end of the first sliding groove 23, the pulling force greater than the friction between the conductor and the inner liner 21 is generated between them. Since the conductor swing is generally instantaneous and repeated, it is rarely continuous in one direction for a long time, so when the conductor swings, most of the time, the inner liner 21 and the clamping portion 11 are abraded, thereby reducing the possibility of abrasion between the conductor and the inner liner 21. When the conductor swings and exerts force on the clamping block 16, the clamping block 16 will slide in an arc trajectory in the second sliding groove 25 by the second sliding block 24, thereby converting the original horizontal friction into circumferential rolling friction, and at the same time, the rotation of the clamping block 16 also reduces the distance between the clamping block 16 and the conductor, so that the clamping effect of the clamping block 16 is improved, and the possibility of loosening of the conductor when it swings is reduced. The side edges of the clamping block 16 are rounded, so that the clamping block 16 is in arc surface contact with the conductor when it rotates and extrudes, which further reduces the abrasion of the conductor compared to the straight edges of the traditional clamping block 16, and improves the protection effect of the strain clamp on the conductor during use.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
