TECHNICAL FIELD

[0001] The present application relates to the technical field of power grid safety, in particular to a steel wire rope breakage holding device for power line stringing traction. BACKGROUND

[0002] In power line stringing construction, steel wire rope as the core traction component undertakes the traction operation of conductor and ground wire, and its running stability directly determines the construction safety and efficiency. However, due to multiple factors, the risk of steel wire rope breakage accident always exists: first, stringing operation often involves large span and high tension working conditions, and steel wire rope is subjected to alternating load for a long time, which is easy to cause fatigue damage; second, the construction environment in the wild is complex, and steel wire rope is easy to be eroded by rain and dust, resulting in corrosion and wear, which weakens the mechanical strength; third, if the traction equipment suddenly fails, it may cause instantaneous overload and breakage of the steel wire rope.

[0003] The existing device has the following disadvantages: it cannot clamp and fix the steel wire rope in time and effectively when the steel wire rope breaks, and some devices can only be fixed by manual operation after the breakage, which is slow in response and cannot meet the demand of quickly and safely handling the breakage problem in actual operation.

[0004] Therefore, the present application proposes a steel wire rope breakage holding device for power line stringing traction to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide a steel wire rope breakage holding device for power line stringing traction to solve the problem that it cannot clamp and fix the steel wire rope in time and effectively when the steel wire rope breaks, and some devices can only be fixed by manual operation after the breakage, which is slow in response and cannot meet the demand of quickly and safely handling the breakage problem in actual operation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11 The present invention provides a technical solution: a wire rope breakage clamping device for power transmission line traction, comprising a fixed frame 1 fixed on the tower, and further comprising: a support unit 3, adjustablely mounted on the fixed frame 1 for supporting the wire rope 5; a first guide wheel 2, mounted on the fixed frame 1 and symmetrically arranged about the support unit 3 for supporting and guiding the wire rope 5; and a clamping unit 4, mounted on the fixed frame 1 for clamping and fixing the wire rope 5 when it breaks.

[0021] It should be noted that during operation, the fixing frame 1 is installed on the tower, and then the steel wire rope 5 is passed through the bottom of the first guide wheel 2 and then through the top of the support unit 3. The steel wire rope 5 exerts a downward pressure on the support unit 3, causing the entire support device to provide rolling support for the steel wire rope 5. Then, the clamping unit 4 is fixed on the fixing frame 1, and the steel wire rope 5 is clamped inside the clamping unit 4. When the steel wire rope 5 breaks, the support unit 3 will move upward. At this time, the linkage device on the support unit 3 will drive the internal components of the clamping unit 4 to move, thereby clamping and fixing the steel wire rope 5 placed inside the clamping unit 4. This process does not require manual intervention and can be automatically triggered at the moment of wire breakage, greatly shortening the response time and effectively preventing personnel injury and equipment damage caused by the inertial splashing of the broken steel wire rope 5, significantly improving the safety of construction.

[0022] In an embodiment, the fixing frame 1 comprises a base frame 11 fixed on the tower for mounting the embracing device, side frames 12 fixed at the upper end of the base frame 11 in intervals for mounting the first guide wheel 2, and a fixing plate 13 fixed on one side of the side frame 12 for fixing the embracing unit 4.

[0023] In this way, the base frame 11 is stably fixed on the tower, thereby providing a solid and reliable mounting basis for the entire embracing device and effectively ensuring that the device can maintain a stable posture in a complex power line stringing environment. Figures 1-5 The side frames 12 are fixed at the upper end of the base frame 11 in intervals, which not only reasonably utilizes the space but also provides an accurate mounting position for the first guide wheel 2, so that the first guide wheel 2 can accurately support and guide the steel wire rope 5, ensuring smooth running of the steel wire rope 5 during traction and reducing friction and wear of the steel wire rope 5, thereby prolonging the service life of the steel wire rope 5.

[0024] In an embodiment, the supporting unit 3 comprises an extension rod 31 fixed at the upper end of the base frame 11, a lifting block 33 fixed at the upper end of the extension rod 31, a third guide wheel 34 fixed at the upper end of the lifting block 33 for rolling support of the steel wire rope 5, and a first elastic member 32 sleeved on the extension rod 31 and located between the base frame 11 and the lifting block 33.

[0025] In this way, the extension rod 31 is fixed at the upper end of the base frame 11, so that the lifting block 33 and the third guide wheel 34 fixed thereon can be adjusted in height. Figures 3-5 In actual power line stringing operations, different sections and different specifications of projects have different requirements for the tension and height of the steel wire rope 5. By adjusting the extension rod 31, the height of the third guide wheel 34 can be easily changed to adapt to various complex working conditions, ensuring that the steel wire rope 5 is always in the best traction state and effectively avoiding problems such as wear and derailment of the steel wire rope 5 due to inappropriate height, thereby improving the stability and reliability of the traction operation.

[0026] In an embodiment, the holding unit 4 comprises: a mounting base 41 fixed on the fixed plate 13 to provide a mounting space for the holding unit 4; a lower clamping plate 42 fixed on the mounting base 41; an upper clamping plate 43 reversibly arranged on one side of the lower clamping plate 42 to clamp the steel wire rope 5 together with the lower clamping plate 42; and a fixing bolt 44 arranged on the upper clamping plate 43 to fix the upper clamping plate 43 and the lower clamping plate 42.

[0027] In this way, as shown in Figures 1-6 , the mounting base 41 is fixed on the fixed plate 13 to provide a solid and reliable mounting space for the holding unit 4, and the lower clamping plate 42 is fixed on the mounting base 41. The upper clamping plate 43 is reversibly arranged on one side of the lower clamping plate 42. When the holding unit 4 is connected to the steel wire rope 5, the steel wire rope 5 is placed inside the lower clamping plate 42, and then the upper clamping plate 43 is flipped to clamp the steel wire rope 5 together with the lower clamping plate 42. Then the fixing bolt 44 is used to fix the upper clamping plate 43 and the lower clamping plate 42. When the steel wire rope 5 is broken, the upper clamping plate 43 and the lower clamping plate 42 can clamp the steel wire rope 5, effectively preventing the broken steel wire rope 5 from further sliding and swinging, and ensuring the safety of the construction site.

[0028] In an embodiment, the holding unit 4 further comprises: a fastening mechanism 45 arranged on the lower clamping plate 42 and connected to the lifting block 33 through the traction rope 6, used to clamp the steel wire rope 5 when it is broken; and a second guide wheel 14 arranged on the fixed plate 13 to guide the traction rope 6.

[0029] In this way, as shown in Figures 1-8 , the fastening mechanism 45 is arranged on the lower clamping plate 42 and connected to the lifting block 33 through the traction rope 6. This structure design realizes the coordinated linkage of the holding unit 4 and the supporting unit 3. When the steel wire rope 5 is broken, the lifting block 33 will displace upward due to the force change caused by the breakage, and this displacement signal will be quickly transmitted to the fastening mechanism 45 through the traction rope 6. The second guide wheel 14 guides the traction rope 6. This coordinated linkage mechanism enables the fastening mechanism 45 to respond quickly at the moment of breakage and clamp the steel wire rope 5 in time, greatly shortening the response time and improving the response ability of the device in emergency situations.

[0030] In an embodiment, the fastening mechanism 45 comprises: a clamping plate 451 arranged obliquely upward towards the side of the side frame 12 and slidingly connected to the mounting base 41. The clamping plate 451 is fixedly connected to the traction rope 6 and moves towards the side of the side frame 12 under the drive of the traction rope 6 to clamp and fix the steel wire rope 5 between the lower clamping plate 42 and the upper clamping plate 43; and a guide rail 411 obliquely arranged and fixed on the mounting base 41 to support the clamping plate 451. The clamping plate 451 is provided with a sliding groove 45101 slidingly connected to the guide rail 411 at the position corresponding to the guide rail 411.

[0031] Thus designed, referring to Figures 5-8 , the clamping plate 451 is arranged upwardly inclined to the side close to the side frame 12 and is slidingly connected to the mounting base 41 and fixedly connected to the traction rope 6. This ingenious structural design cleverly utilizes the inclined angle and the sliding connection mode. When the steel wire rope 5 is broken, the clamping plate 451 is driven by the traction rope 6 to move upwardly while moving to the side close to the side frame 12, so that the steel wire rope 5 between the upper and lower clamping plates is clamped and fixed, reducing the energy loss and action delay of the intermediate links and improving the overall reaction speed of the device. The guide rail 411 is arranged inclinedly and fixedly on the mounting base 41, providing stable support and precise guidance for the clamping plate 451. The sliding groove 45101 arranged at the position corresponding to the guide rail 411 on the clamping plate 451 is slidingly connected to the guide rail 411. This matching mode ensures that the clamping plate 451 always moves along the predetermined track during the movement process and cannot deviate or shake, improving the reliability and stability of the action.

[0032] In an embodiment, the fastening mechanism 45 further comprises a fixing member 452 arranged telescopically in the mounting base 41 and used for fixing the clamping plate 451 after the clamping plate 451 moves to the set position.

[0033] Thus designed, referring to Figure 8 , the telescopic property of the fixing member 452 enables it to accurately adapt to the state of the clamping plate 451 after the clamping plate 451 moves to the set position. When the clamping plate 451 completes the clamping action on the steel wire rope 5 under the drive of the traction rope 6 and reaches the set position, the fixing member 452 extends and firmly fixes the clamping plate 451, effectively avoiding displacement of the clamping plate 451 due to external force in the subsequent use process, thereby ensuring the stability of the structure of the entire fastening mechanism 45 and ensuring that the steel wire rope 5 can always be in a stable clamping state.

[0034] In an embodiment, the fixing member 452 comprises a lifting plate 4521 arranged inside the mounting base 41, the mounting base 41 being provided with a mounting hole 41102 for the movement of the lifting plate 4521; a fixing block 4522 arranged at the upper end of the lifting plate 4521 and upwardly penetrating the guide rail 411, used for clamping and fixing the clamping plate 451; and a second elastic member 4523 made of a spring with damping or an elastic pad, arranged at the lower end of the lifting plate 4521 and used for supporting the lifting plate 4521.

[0035] Thus designed, referring to Figures 9-11In normal use of the steel wire rope 5, the fixed block 4522 abuts against the lower end of the clamping plate 451, the lifting plate 4521 is arranged inside the mounting seat 41, and the mounting hole 41102 formed on the mounting seat 41 provides an accurate guide path for the movement of the lifting plate 4521, which ensures that the lifting plate 4521 can stably move in the vertical direction. The fixed block 4522 is arranged at the upper end of the lifting plate 4521 and penetrates the guide rail 411 upward. When the clamping plate 451 moves to the set position, the lifting plate 4521 drives the fixed block 4522 to rise, and the fixed block 4522 can be clamped and fixed with the corresponding structure on the clamping plate 451, thereby improving the structural reliability of the entire fastening mechanism 45 and ensuring that the steel wire rope 5 can always be in a stable clamping state. The second elastic member 4523 is arranged at the lower end of the lifting plate 4521 and provides elastic support for the lifting plate 4521. After the clamping plate 451 moves to the set position, the second elastic member 4523 drives the fixed block 4522 to move upward and be clamped and fixed with the clamping plate 451.

[0036] In an embodiment, the mounting seat 41 is provided with an empty groove 41101 for the movement of the fixed block 4522, and the lower end of the clamping plate 451 is provided with a fixing groove 45102 for fixing the fixed block 4522.

[0037] In this way, referring to Figures 9-11 , the empty groove 41101 provides an accurate guide path for the movement of the fixed block 4522, ensuring that the fixed block 4522 can only move within a set range. After the fixing groove 45102 at the lower end of the clamping plate 451 moves above the fixed block 4522, the second elastic member 4523 drives the lifting plate 4521 to move upward, the lifting plate 4521 drives the fixed block 4522 to rise, and the fixed block 4522 enters the fixing groove 45102 at the lower end of the clamping plate 451, so that the clamping plate 451 can stably and reliably clamp the steel wire rope 5, effectively preventing the steel wire rope 5 from slipping or loosening during use, thereby ensuring the safety and stability of the power line stringing operation.

[0038] In an embodiment, the upper end of the clamping plate 451 is fixed with an anti-skid tooth 4511.

[0039] In this way, referring to Figure 11 , the arrangement of the anti-skid tooth 4511 significantly increases the friction coefficient between the upper end of the clamping plate 451 and the steel wire rope 5. During clamping, the anti-skid tooth 4511 can penetrate the surface of the steel wire rope 5 to form multiple small contact points and friction force points.

[0040] In addition, if the description in the embodiments involves "first", "second", etc., the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.
