Description

Technical Field

[0001] This invention relates to the technical field of wire tensioners, and more particularly to an insulating wire tensioner and a fastening device. Background Technology

[0002] Commonly used tools in fields such as construction and installation, these wire rope tensioners are mainly used to tighten cables, wire ropes, or to bind and fix objects. Existing insulated wire rope tensioners typically consist of a tensioning box, a winding post, and a hook. The wire rope is wound and tightened by manually turning the handle or lever to rotate the winding reel.

[0003] In actual operation, traditional manual control wire tensioners have obvious defects. Due to the huge tension of the cable, the operator needs to expend a lot of physical strength when winding the cable, and relies entirely on manual feel to control the winding speed and force. It is very easy for the wire rope to jump off the winding post, get stuck or even break due to excessive force or uneven speed, which poses a safety hazard.

[0004] When tightening or maintaining a taut state after tightening, existing locking structures often rely solely on simple fixing structures and manual anti-reverse measures. However, under high tension or vibration conditions, slippage or insecure locking can easily occur, leading to accidental loosening of the wire rope, which affects construction progress and installation quality. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above-mentioned insulation tensioners and fastening devices, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to provide an insulating wire tensioner and fastening device, which aims to: mechanize wire winding, lock control, prevent wire harness lock reversal, assist in cooling, and provide insulation protection.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wire harness mechanism, comprising a tensioning box, wherein a shaft plate is fixedly connected to the right side of the inner wall of the tensioning box, two shaft plates are provided and respectively fixed to the front end and back end of the inner wall of the tensioning box, a winding post is fixedly connected to the inner side of the shaft plate, a steel wire rope is provided on the surface of the winding post, the steel wire rope is wound around the surface of the winding post, and hooks are fixedly connected to both ends of the steel wire rope; characterized in that:

[0009] A take-up mechanism includes a take-up reel, which is disposed inside a tensioning box. There are two take-up reels. A take-up post is fixedly connected to the inner side of the take-up reel.

[0018] In a preferred embodiment of the insulating wire tensioner and fastening device of the present invention, a smooth inclined surface is provided on the left side of the movable block and the right side of the control block, and a sliding inclined surface is provided on the left side of the locking block and the right side of the trapezoidal block.

[0019] In a preferred embodiment of the insulating wire tensioner and fastening device of the present invention, an auxiliary wrench is fixedly connected to the front end of the locking block, and the front end of the auxiliary wrench passes through the front end of the wire tensioning box.

[0020] In a preferred embodiment of the insulating wire tensioner and fastening device of the present invention, the front end and back end of the tensioning box are provided with sliding grooves corresponding to the position of the auxiliary wrench. The surface of the auxiliary wrench is slidably connected to the sliding grooves provided on the surface of the tensioning box.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention sets up a take-up mechanism and a control mechanism. The control mechanism drives the control block on the take-up reel, thereby realizing the control of the take-up speed of the wire rope and the balance of the take-up force. This solves the problems of laborious operation and unstable take-up of traditional manual wire tensioners, and improves the stability and efficiency of operation.

[0025] 2. By setting up a locking mechanism and an anti-loosening mechanism, the present invention locks the take-up reel immediately after the control mechanism completes the take-up action, which avoids the wire rope from being unable to be fully tightened by the force of the control mechanism under high tension. It also prevents the control cylinder in the control mechanism from loosening or reversing during the return stroke. At the same time, the piston movement generates cold air to assist in cooling, which cools the key parts and indirectly assists in the anti-loosening effect, thus improving the reliability and safety of locking.

[0026] 3. By providing an auxiliary wrench, the operator can manually control the lifting of the locking block from outside the tensioning box, thereby quickly releasing the locking state of the locking mechanism, facilitating the release of the wire rope tension, and unwinding the wire rope tightening, greatly improving the convenience of operation.

[0027] 4. This invention ensures safe operation in live environments by making the surfaces of the tensioning box and auxiliary wrench in insulating material and by setting a sliding rod to guide the direction of the wire rope. It also avoids entanglement or friction damage to the wire rope during the winding and unwinding process, thereby enhancing safety and ease of operation. Attached Figure Description

[0042] Example 1

[0043] The wire harness mechanism 100 includes a wire tensioning box 101. A shaft plate 102 is fixedly connected to the right side of the inner wall of the wire tensioning box 101. Two shaft plates 102 are provided and fixed to the front end and back end of the inner wall of the wire tensioning box 101, respectively. A wire winding post 103 is fixedly connected to the inner side of the shaft plate 102. A wire rope 104 is provided on the surface of the wire winding post 103. The wire rope 104 is wound on the surface of the wire winding post 103. Both ends of the wire rope 104 are fixedly connected to hooks 105.

[0044] One embodiment of this example is as follows: a take-up mechanism 200, which includes a take-up reel 201, which is disposed inside a tensioning box 101. There are two take-up reels 201. A take-up post 202 is fixedly connected to the inner side of the take-up reel 201. The surface of the take-up post 202 is in contact with the wire rope 104. The wire rope 104 is wound around the surface of the take-up post 202. A control block 203 is slidably connected to the surface of the take-up reel 201. Several control blocks 203 are provided and are evenly distributed. The top of the control block 203 penetrates the top of the take-up reel 201.

[0045] By setting up the take-up mechanism 200, the wire harness mechanism 100 can be assisted in tightening the wire rope 104, which solves the problem that the take-up force is difficult to control accurately due to manual rotation of the take-up reel 201, and that the wire rope 104 is prone to jamming or uneven winding due to sudden tension changes during the take-up process of the wire rope 104 because the unidirectional winding is carried out by the winding column 103.

[0046] A take-up spring 203a is fixedly connected to the bottom of the control block 203, and the bottom of the take-up spring 203a is fixedly connected to the inner cavity of the take-up reel 201.

[0047] By setting the take-up spring 203a, an automatic reset force can be provided to the control block 203, so that the control block 203 can quickly return to the initial position after being pushed and compressed by the movable block 307, keeping the top always in a ready-to-push state. This solves the problem that the control block 203 cannot automatically reset when the movable block 307 retracts, causing it to lose contact with the movable block 307 and thus be unable to push again. This ensures that the control mechanism 300 can continuously and stably drive the take-up reel 201 to rotate.

[0048] A sliding rod 101b is fixedly connected to the right side of the tension box 101 and at the position corresponding to the steel wire rope 104. The top of the sliding rod 101b is in contact with the bottom of the steel wire rope 104.

[0049] By setting the sliding rod 101b, the wire rope 104 can be assisted to slide during the winding and unwinding process, avoiding the wire rope 104 from swaying left and right or jumping up and down between the winding post 103 and the take-up post 202, thus solving the problem of damage caused by friction between the wire rope 104 and the edge of the tension box 101 due to the shaking of the wire rope 104.

[0050] Example 2

[0051] Based on Embodiment 1, this embodiment considers that although the winding mechanism 200 can achieve the winding of the wire rope 104, in actual operation it still relies on manual pushing or rotating for tightening, which is not only laborious but also difficult to maintain efficiency, and is prone to problems such as uneven winding force causing the wire rope 104 to shake or even jam. Therefore, this embodiment sets up a control mechanism 300, which includes two fixing rods 301. The bottom of the fixing rod 301 is fixedly connected to the top of the tensioning box 101, and the top of the fixing rod 301 is fixedly connected to... A fixed plate 302 is fixedly connected to the bottom of the fixed plate 302. A fixed column 304 is fixedly connected to the left side of the control cylinder 303. The back end of the fixed column 304 is fixedly connected to the back end of the inner wall of the tension box 101. A support plate 305 is fixedly connected to the inner side of the fixed column 304. A sliding plate 306 is slidably connected to the bottom of the fixed column 304 through a sliding groove. The top right side of the sliding plate 306 is fixedly connected to the right side of the bottom of the control cylinder 303. A movable block 307 is fixedly connected to the bottom left side of the sliding plate 306. The right side of the movable block 307 contacts the right side of the control block 203.

[0052] By setting up a control mechanism 300, the take-up reel 201 is automatically driven. The reciprocating motion of the control cylinder 303 drives the slide plate 306 and the movable block 307 to slide, so that the movable block 307 repeatedly pushes the control blocks 203 evenly distributed on the surface of the take-up reel 201, converting the linear motion of the control cylinder 303 into the intermittent rotational motion of the take-up reel 201, which assists the wire rope 104 in taking up the wire, balances the take-up force and controls the take-up speed, and solves the problem of laborious and inefficient manual operation.

[0053] A rectangular plate 307a is fixedly connected to the left side of the movable block 307, and a synchronization plate 307b is fixedly connected to the inner side of the rectangular plate 307a.

[0054] By setting up rectangular plate 307a and synchronization plate 307b, the movable block 307 can synchronously push multiple control blocks 203, so that the thrust can be evenly distributed to multiple force points of the take-up reel 201, solving the problem of uneven force when the movable blocks 307 on both sides come into contact, and improving the stability of the take-up process.

[0055] Example 3

[0056] Based on Embodiment 2, this embodiment considers that the control mechanism 300 in Embodiment 2 can achieve mechanized driving of the take-up reel 201 to rotate, solving the problem of laborious manual operation. However, some problems still exist. The control mechanism 300 adopts an intermittent pushing method. During the interval when the movable block 307 completes one push and retracts, the take-up reel 201 only relies on friction to maintain its position. When the wire rope 104 is under large tension, it is very easy to reverse or loosen, causing the tightened wire rope 104 to loosen, affecting the construction quality and work efficiency. Therefore, this embodiment sets up a locking mechanism 400. The locking mechanism 400 includes a retaining ring 401. The back end of the retaining ring 401 is fixedly connected to the front end of the take-up reel 201. The front end of the retaining ring 401 is connected to the front end of the inner wall of the tensioning box 101. A spring-loaded spring 402 is provided on the contact surface between the retaining ring 401 and the tensioning box 101 via a rotating shaft. The spring-loaded spring 402 rotates in cooperation with the retaining ring 401 and the tensioning box 101. A trapezoidal block 403 is fixedly connected to the surface of the retaining ring 401. Several trapezoidal blocks 403 are provided and are evenly distributed. A metal plate 404 is fixedly connected to the front end and back end of the inner wall of the tensioning box 101 and to the top of the retaining ring 401. A hollow block 405 is fixedly connected to the back end of the metal plate 404. A retaining plate 406 is slidably connected to the inner cavity of the hollow block 405. A spring assembly 407 is fixedly connected to the top of the retaining plate 406. The top of the spring assembly 407 is fixedly connected to the inner cavity of the hollow block 405. A retaining block 408 is fixedly connected to the bottom of the retaining plate 406. The right side of the retaining block 408 contacts the left side of the trapezoidal block 403.

[0057] By setting up a locking mechanism 400, the rotation direction of the take-up reel 201 is instantly locked. When the control mechanism 300 pushes the take-up reel 201 to rotate and tighten the wire rope 104, the retaining ring 401 rotates synchronously with the take-up reel 201, and the trapezoidal block 403 slides under the retaining block 408 in sequence. When the take-up reel 201 has a tendency to reverse, the retaining block 408 immediately engages with the gap of the trapezoidal block 403 under the elastic force of the spring group 407, preventing reverse reversal. At the same time, the tension of the spring 402 ensures that the retaining ring 401 is locked in time and that the tightening and rebound force of the take-up column 202 are maintained. This achieves anti-reverse protection during the lull of the control mechanism 300's tightening, ensuring that the wire rope 104 is always in a taut state, improving the reliability of take-up and the efficiency of operation.

[0058] Smooth inclined surfaces 307c are provided on the left side of the movable block 307 and the right side of the control block 203, and sliding inclined surfaces 307d are provided on the left side of the locking block 408 and the right side of the trapezoidal block 403.

[0059] By setting a smooth inclined surface 307c and a sliding inclined surface 307d, the two can gradually fit together when pushed, reducing hard impact and instantaneous resistance, achieving smooth transmission of thrust, and avoiding wear caused by right-angle contact. The sliding inclined surface 307d opened on the contact surface between the locking block 408 and the trapezoidal block 403 allows the locking block 408 to slide smoothly along the inclined surface when it falls into the gap of the trapezoidal block 403, ensuring that it is locked in place.

[0060] An auxiliary wrench 408a is fixedly connected to the front end of the locking block 408, and the front end of the auxiliary wrench 408a passes through the front end of the tightening box 101.

[0061] By setting an auxiliary wrench 408a, the function of manually releasing the locking state can be realized. When it is necessary to release the tension of the wire rope 104, the operator can move the auxiliary wrench 408a to lift the locking block 408 upward, so that the locking block 408 is disengaged from the trapezoidal block 403, thereby releasing the locking mechanism 400 from locking the take-up reel 201. This solves the problem that the wire rope 104 cannot be released quickly in the locked state, improves the flexibility of operation, and facilitates disassembly and adjustment after take-up.

[0062] The front and back ends of the wire tensioning box 101 are provided with sliding grooves 101a at positions corresponding to the auxiliary wrench 408a. The surface of the auxiliary wrench 408a is slidably connected to the sliding grooves 101a provided on the surface of the wire tensioning box 101.

[0063] By setting the sliding groove 101a, the movement trajectory of the auxiliary wrench 408a is guided and limited. Under the constraint of the sliding groove 101a, the auxiliary wrench 408a can only move in a predetermined direction, ensuring that the locking block 408 is raised or lowered. This solves the problem of the auxiliary wrench 408a not engaging properly due to deviation or shaking during operation, and improves the smoothness of the unlocking action.

[0064] Example 4

[0065] Based on Embodiment 3, this embodiment considers that the locking mechanism 400 in Embodiment 3 can achieve the anti-loosening and anti-derailment function of the wire rope 104. However, problems still exist. After the locking block 408 and the trapezoidal block 403 are engaged and locked, there is an unavoidable fit gap in the structure. When the wire rope 104 is subjected to tension fluctuations, the take-up reel 201 will still experience microscopic reverse swaying. This micro-movement not only leads to insufficient locking stability, but also increases the wear of the meshing surfaces of the locking block 408 and the trapezoidal block 403, causing the fit gap to gradually increase over time. At the same time, the frictional heat generated during operation and in key parts cannot be dissipated in time, resulting in excessive local temperature rise. This causes the metal to expand thermally, changing the preset fit gap. On the other hand, it accelerates the spring assembly The thermal fatigue of 407 ultimately affects the lifespan of the locking mechanism 400. Therefore, in this embodiment, an anti-loosening mechanism 500 is provided. The anti-loosening mechanism 500 includes an anti-loosening plate 501. The top of the anti-loosening plate 501 is fixedly connected to the bottom of the metal plate 404. An anti-loosening block 502 is movably connected to the bottom of the anti-loosening plate 501 through a rotating shaft. A hollow rod 503 is fixedly connected to the bottom of the anti-loosening block 502. An anti-loosening spring 504 is fixedly connected to the inner cavity of the hollow rod 503. A solid rod 505 is fixedly connected to the bottom of the anti-loosening spring 504. The surface of the solid rod 505 is slidably connected to the inner cavity of the hollow rod 503. The bottom of the solid rod 505 is movably connected to the top of the locking block 408 through a rotating shaft. A vent hole 506 is provided on the surface of the anti-loosening block 502.

[0066] By setting the anti-loosening mechanism 500, the solid rod 505 applies a continuous downward elastic force to the locking block 408. When the locking block 408 falls into the tooth groove of the trapezoidal block 403 under the action of the spring assembly 407, the additional thrust of the anti-loosening spring 504 makes the locking block 408 keep in close contact with the force-bearing surface of the trapezoidal block 403 in real time, actively compensating for the fit gap. Even if the wire rope 104 is subjected to tension fluctuations and the take-up reel 201 has a microscopic reversal tendency, the locking block 408 can maintain contact with the trapezoidal block under the action of elastic force, reducing the micro-movement phenomenon from the root and significantly improving the stability and reliability of locking. At the same time, the heat generated by friction is blown from the gap between the hollow rod 503 and the solid rod 505 to the locking block 408 and the trapezoidal block 403 in time, preventing the metal thermal expansion deformation caused by excessive local temperature rise, ensuring that the preset fit gap remains stable during operation, reducing the thermal load of the spring assembly 407, and extending the overall service life of the locking mechanism 400.

[0067] Example 5

[0068] Based on Embodiment 1, this embodiment takes into account that the wire harness mechanism 100 and the take-up mechanism 200 in Embodiment 1 can achieve basic tightening of the wire rope 104. However, in the construction environment, the tightening box 101 and the exposed operating parts are all made of metal. During operation, they are electrified and are very likely to cause electric shock accidents, which poses a serious safety hazard. Therefore, this embodiment is equipped with insulating material. The surfaces of the tightening box 101 and the auxiliary wrench 408a are all equipped with insulating material.

[0069] By incorporating insulating materials, the device achieves isolation and protection between operators and high-voltage electricity. By covering the surface of the tension box 101 and the auxiliary wrench 408a with an insulating layer, the entire device has reliable insulation performance in a live environment, solving the problem of poor safety and achieving the protective effect of ensuring the personal safety of operators.

[0070] In summary, the operator uses hooks 105, which are fixedly connected to both ends of the wire rope 104, to hang the device on the anchor points that need to be tensioned. At this time, the wire rope 104 is pre-wound around the surface of the winding post 103. The winding post 103 is fixedly installed on the right side of the inner wall of the tension box 101 through the shaft plate 102. The two shaft plates 102 are fixed to the front end and the back end of the inner wall of the tension box 101, respectively, to ensure the stable support of the winding post 103.

[0071] After the connection is completed, the wire rope 104 is in a slack state, and the wire rope 104 contacts the surface of the take-up post 202 and is wound around the surface of the take-up post 202. The take-up post 202 is fixedly connected to the inside of two take-up reels 201. The two take-up reels 201 are set in the tension box 101. Their rotation will directly drive the take-up post 202 to wind up the wire rope 104.

[0072] To ensure that the wire rope 104 maintains a stable direction during winding and unwinding and to avoid friction or jamming with the edge of the tension box 101, a sliding rod 101b is fixedly connected to the right side of the tension box 101 corresponding to the position of the wire rope 104, providing smooth guiding support for the wire rope 104.

[0073] When the control mechanism 300 is activated, the control cylinder 303 of the control mechanism 300 begins to reciprocate and extend. The control cylinder 303 is securely mounted on the top of the tension box 101 via the fixing plate 302 and two fixing rods 301. The left side of the control cylinder 303 is fixedly connected to the back end of the inner wall of the tension box 101 via the fixing column 304. The support plate 305 fixedly connected to the inner side of the fixing column 304 further enhances the rigidity of the overall structure, ensuring that the control cylinder 303 operates stably without shaking.

[0074] The telescopic rod of the control cylinder 303 pushes the slide plate 306 to slide precisely left and right in the groove at the bottom of the fixed column 304. When the slide plate 306 slides to the left, the movable block 307 fixedly connected to the bottom of its left side moves to the left at the same time. The right side of the movable block 307 contacts the right side of the control block 203 slidably connected to the surface of the take-up reel 201 and applies a thrust. Both the left side of the movable block 307 and the right side of the control block 203 are provided with smooth inclined surfaces 307c, which smoothly transmit the thrust to the control block 203, avoiding jamming and wear caused by hard impact. Under the action of the thrust, the control block 203 drives the take-up reel 201 to rotate at a certain angle, which drives the take-up column 202 to wind up a section of wire rope 104, completing the take-up action.

[0075] When the control cylinder 303 drives the slide plate 306 to retract to the right, in order to ensure that the control block 203 can automatically reset to prepare for the next push, a take-up spring 203a is fixedly connected to the bottom of the control block 203. When the movable block 307 retracts, the spring force causes the control block 203 to quickly spring back to the initial through state.

[0076] While the control mechanism 300 pushes the take-up reel 201 to rotate and tighten, the locking mechanism 400 locks simultaneously to prevent reverse rotation during the lull in the winding process. The back end of the locking ring 401 of the locking mechanism 400 is fixedly connected to the front end of the take-up reel 201, so the locking ring 401 and the take-up reel 201 rotate synchronously. The front end of the locking ring 401 is movably connected to the front end of the inner wall of the tension box 101 through a rotating shaft. The spring 402 provides tension to ensure that the locking ring 401 and the take-up reel 201 complete the winding and unwinding actions. When the control mechanism 300 and the locking structure no longer provide force, the elastic force provided by the spring 402 can release the wound wire rope 104.

[0077] When the control mechanism 300 completes one push and retraction, the huge tension of the wire rope 104 will attempt to cause the take-up reel 201 to rotate in reverse. At this time, the left side of the locking block 408 will immediately lock into the right side gap of the trapezoidal block 403, forming a one-way lock and effectively preventing reverse rotation.

[0078] The top of the anti-loosening plate 501 is fixedly connected to the bottom of the metal plate 404. The bottom of the plate is movably connected to the anti-loosening block 502 via a pivot. When the locking block 408 completes one action by pressing against the trapezoidal block 403, the solid rod 505 simultaneously completes one piston movement in the inner cavity of the hollow rod 503. At this time, the anti-loosening spring 504 rebounds quickly, assisting the locking block 408 to press against the trapezoidal block 403 to the right, ensuring timely locking action and further eliminating gaps during locking. At the same time, when the solid rod 505 performs one piston movement in the inner cavity of the hollow rod 503, it pushes the airflow into the inner cavity of the solid rod 505 and releases it through the vent 506, forming an intermittent airflow that blows cold air to the pipe fitting for cooling, which is used for local cooling and cooling of critical parts, indirectly assisting the anti-loosening effect.

[0079] When the tightening operation is completed and the device needs to be disassembled, the operator can manually release the locking state of the locking mechanism 400. The front end of the locking block 408 is fixedly connected to an auxiliary wrench 408a, the front end of which passes through the front end of the tensioning box 101. The operator only needs to push the auxiliary wrench 408a upward to drive the locking block 408 to overcome the elastic force of the spring group 407 and lift it upward, so that the locking block 408 is disengaged from the trapezoidal block 403, thereby releasing the locking mechanism 400, pulling the wire rope 104, releasing the tension, and disassembling the device.

[0080] Throughout the operation, the surfaces of the tightening box 101 and the auxiliary wrench 408a are covered with insulating material to isolate high voltage electricity and ensure the safety of operators in a live environment.
