Description

Technical Field

[0001] This invention relates to the field of power fittings technology, specifically to a high-strength safety backup clamp for power fittings. Background Technology

[0002] In patent application CN114498508A, a fixing plate, a cable harness sleeve, and a connecting sleeve are included. The cable harness sleeve is located on one side of the fixing plate, and the connecting sleeve is located above the cable harness sleeve. A fixing guide rail is provided on one side of the fixing plate surface. The advantages are: Through the arrangement of the fixing guide rail, the first fixing buckle, the stop screw, and the fastening nut, the fixing plate can achieve a good fixing effect. The combination of the fixing guide rail, the first fixing buckle, the stop screw, and the fastening nut uses a sliding fixing method, which allows for fine adjustment of the fixing position of the first fixing buckle, thereby improving the applicability of the cable clamp. The combination of the stop screw and the fastening nut uses a threaded connection fixing method, which provides a good fixing effect and facilitates quick assembly and disassembly. The combination of the positioning screw and the first fixing buckle allows for quick connection to the cable.

[0003] In the aforementioned patents or prior art, the backup cable clamp already bears a certain amount of tension during installation. When the main rope is affected by crosswinds or other conditions, the backup rope cannot adjust its tension independently to offset the additional tension borne by the main rope when it swings. Since the secondary rope is a rigid connection, if the main rope breaks, it will generate an extremely strong tension on the secondary rope in an instant, which places high demands on the locking force of the secondary rope. If it is in a windy environment for a long time and the rope swings frequently, it will affect the locking effect and may loosen, thus affecting the locking effect. Summary of the Invention

[0004] The problem this invention aims to solve is that the secondary rope lacks an independent tension adjustment function, and the backup clamp may loosen over long-term use, potentially affecting the locking effect.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a high-strength safety backup clamp for power fittings, including a main rope, a secondary rope at the top of the main rope, an upper clamp fixedly connected to one end of the secondary rope, a lower clamp at the bottom of the upper clamp, and the lower clamp and the upper clamp being fixedly connected by bolts.

[0006] Preferably, the inner arc surfaces of the upper and lower clamps are in contact with the outer arc surface of one end of the main rope. The inner arc surface of the lower clamp is provided with a plurality of locking wheels in an array. The outer arc surface of the locking wheels is provided with locking teeth. The two sides of the locking wheels are provided with rotating shafts. All of the locking wheels are adapted to the inner arc surface of the lower clamp.

[0007] Preferably, the other end of the auxiliary rope is provided with a wheel, and the outer arc surface of the wheel is provided with a fixing buckle, and the other end of the auxiliary rope is fixedly connected to the fixing buckle.

[0008] Preferably, the inner arc surface of the wheel is provided with an inner wheel, the outer arc surface of the inner wheel is provided with a sloping stop, and the outer arc surface of the inner wheel is rotatably connected to the inner arc surface of the wheel.

[0009] Preferably, a plurality of teeth are provided on one side of the wheel, and sliders are provided on both the front and rear sides of the teeth.

[0010] Preferably, the locking teeth and the slider are both adapted to the wheel, and one side of the locking teeth is adapted to the inclined surface of the inclined block.

[0011] Preferably, a ring is provided on one side of the wheel, and one side of the ring is fixedly connected to the inner arc surface of the inner wheel.

[0012] Preferably, a connecting plate is provided at the other end of the main rope, and one side of the connecting plate is rotatably connected to the other end of the main rope.

[0013] Preferably, a traction rope is provided on the other side of the connecting plate, and one end of the traction rope is rotatably connected to the other side of the connecting plate.

[0014] Preferably, a grounding rope is provided at the bottom of the main rope, and one end of the grounding rope is fixedly connected to the bottom of the main rope.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: This device employs a dual-safety structure consisting of a wheel and a locking wheel, creating a highly reliable backup protection system through a precise mechanical linkage design. When the main rope unexpectedly breaks due to fatigue or impact, the locking mechanism responds instantly, allowing the auxiliary rope to smoothly bear the entire load. Through a multi-point stress distribution design, the auxiliary rope maintains structural integrity even under extreme stress conditions, preventing slippage or detachment. Structurally, this solution pursues a highly integrated and modular layout, incorporating complex locking logic into a compact structure, significantly simplifying on-site installation and commissioning processes. Operators can quickly complete deployment without specialized tools, effectively improving construction efficiency. The device's innovative wheel structure design demonstrates superior dynamic response capabilities when dealing with crosswind interference in daily use. When crosswinds cause the rope to swing violently, resulting in instantaneous fluctuations in tension, the wheel mechanism automatically activates the locking wheel thanks to its unique mechanical properties, putting the auxiliary rope into an adaptive locking state. This process requires no manual intervention and is completed entirely through the structure's own mechanical feedback, achieving instant supplementation of the auxiliary rope's tension. This effectively shares the additional dynamic load borne by the main rope during swinging. Through this mechanism, the structural strength of the main rope under normal working conditions is fully preserved, avoiding the accumulation of fatigue damage caused by long-term alternating stress and significantly extending the main rope's service life. Simultaneously, this active tension-sharing design reduces the need for frequent replacements due to rope wear or performance degradation, lowering equipment maintenance costs and downtime losses from a life-cycle perspective. While ensuring operational safety, this structural innovation effectively achieves the engineering goal of cost reduction and efficiency improvement by enhancing the durability and reliability of key consumables.

[0021] The inner arc surfaces of the upper clamp 6 and the lower clamp 7 are in contact with the outer arc surface of one end of the main rope 1. The inner arc surface of the lower clamp 7 is provided with a number of locking wheels 14 in an array. The outer arc surface of the locking wheels 14 is provided with locking teeth 15. The two sides of the locking wheels 14 are provided with rotating shafts 16. The locking wheels 14 are all adapted to the inner arc surface of the lower clamp 7.

[0022] The other end of the auxiliary rope 2 is provided with a wheel 5, and the outer arc surface of the wheel 5 is provided with a fixing buckle 13. The other end of the auxiliary rope 2 is fixedly connected to the fixing buckle 13.

[0023] The inner arc surface of the wheel 5 is provided with an inner wheel 9, and the outer arc surface of the inner wheel 9 is provided with a sloping stop block 10. The outer arc surface of the inner wheel 9 is rotatably connected to the inner arc surface of the wheel 5.

[0024] A number of locking teeth 11 are provided on one side of the wheel 5, and sliders 12 are provided on the front and rear sides of the locking teeth 11.

[0025] Both the tooth 11 and the slider 12 are adapted to the wheel 5, and one side of the tooth 11 is adapted to the inclined surface of the inclined block 10.

[0026] A ring 4 is provided on one side of the wheel 5, and one side of the ring 4 is fixedly connected to the inner arc surface of the inner wheel 9.

[0027] A connecting plate 17 is provided at the other end of the main rope 1, and one side of the connecting plate 17 is rotatably connected to the other end of the main rope 1.

[0028] A traction rope 8 is provided on the other side of the connecting plate 17, and one end of the traction rope 8 is rotatably connected to the other side of the connecting plate 17.

[0029] A grounding rope 3 is provided at the bottom of the main rope 1, and one end of the grounding rope 3 is fixedly connected to the bottom of the main rope 1.

[0030] The working principle and usage process of this invention: When installing the cable, the worker first fixes the pulley 5 at one end of the auxiliary rope 2 to the top of the tower with the ring buckle 4. At the same time, the upper clamp 6 and lower clamp 7 at the other end are wrapped around the main rope 1 and then locked with bolts to ensure that the auxiliary rope 2 can bear part of the tension of the main rope 1 after being fully stretched and locked. After installation and put into use, if a large crosswind causes the main rope 1 to swing laterally, the auxiliary rope 2 will be stretched to a certain extent. When the stretching occurs, the auxiliary rope 2 will drive the pulley 5 to rotate clockwise. Since the inner pulley 9 is fixedly connected to the ring buckle 4, there will be a speed difference between the pulley 5 and the inner pulley 9. The locking teeth 11 set inside the pulley 5 move along the inclined surface of the inclined block 10 on the outer arc surface of the inner pulley 9 under the limiting action of the sliders 12 on both sides, so that the top of the locking teeth protrudes outward until it abuts against the outer arc surface of the auxiliary rope 2 to achieve the locking effect, so that the auxiliary rope 2 can bear more tension and ensure that the structural strength of the main rope 1 is not damaged. In extreme cases, if the main rope 1 breaks, the auxiliary rope 2 will bear all the tension instantly. If the locking effect of the backup clamp is insufficient, the main rope 1 will slip. Several locking wheels 14 installed on the inner arc surface of the lower clamp 7 will rotate clockwise under the drive of the main rope 1, so that the locking teeth 15 will gradually produce an additional locking effect on the main rope 1, ensuring that the main rope 1 is completely locked and will not fall off.
