Description

Technical Field

[0001] The present invention relates to the technical field of wire twisting devices, in particular to a wire twisting device for producing fireproof electric wires. Background Art

[0002] Fire-resistant wires are mainly used to maintain power supply and signal transmission in environments such as fire or high temperature. In the preparation process of fire-resistant wires, twisting is one of the key links. The twisting process twists multiple single wires together according to certain rules to form a conductor structure with certain flexibility and mechanical strength. This process not only determines the electrical properties of the fire-resistant wires (such as resistance and current carrying capacity), but also directly affects its mechanical properties (such as tensile strength and bending performance). Twisting equipment, as the core tool for realizing the twisting process, ensures that the final conductor meets the design requirements by controlling the tension, twisting angle and speed of the single wires.

[0003] Patent application number 202510126227.9 provides a cable tension control stranding device, comprising a base, a stranding motor fixedly mounted on the upper end of the base, rotatable racks fixedly mounted on both sides of the upper end of the base, the stranding motor output end connected to the stranding shaft via a transmission belt, the stranding shaft rotatably mounted within the rotatable rack, one end of the stranding shaft fixedly connected to a winding drum, the winding drum fixedly connected to a first tensioning drum via circumferentially evenly distributed winding shafts, each winding shaft rotatably mounted with a winding roller, the first tensioning drum fixedly connected to the second tensioning drum via a boss, the boss being provided with a tensioning assembly. The present invention achieves tension control and adjustment during the cable conveying process by varying the spacing of the tensioning pulleys.

[0004] During use, the above structure adjusts the tension of the cable by changing the spacing of the tensioning wheel. However, it can be seen from the patent that the cable will pass through multiple bending points. These bending points will cause the single wire to bend repeatedly, thereby causing the metal material to gradually fatigue. Metal fatigue will reduce the mechanical strength of the single wire and increase the risk of wire breakage, thereby affecting the quality of the stranded wire and subsequent single wire performance.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention. Example

[0020] A stranding device for producing fireproof wires, such as Figures 1-6 As shown, it includes a support platform 1, the support platform 1 is fixed with several fixed frames 2, and a rotating member 3 is rotatably connected between the several fixed frames 2. The support platform 1 is provided with a first driving member 4 for driving the rotating member 3 to rotate. The first driving member 4 is a driving motor. In this device, the driving shaft of the first driving member 4 is connected to the rotating member 3 through a pulley belt. In actual use, the driving shaft of the first driving member 4 can be connected to the rotating member 3 through other power elements, such as a gear box. A guide frame 5 is provided on the side of the support platform 1 away from the first driving member 4. The guide frame 5 is used to merge multiple single lines. The rotating member 3 is fixed with a circular array distributed on the side facing the guide frame 5. The connecting frame 6 and the circular array distribution connecting frame 6 are fixed with arc-shaped elastic plates 7 on the opposite sides. The arc-shaped elastic plate 7 is fixed with guides 8 evenly distributed along its edge line. All the guides 8 on the same arc-shaped elastic plate 7 are used to guide the single line and control the tension of the single line. The guide 8 is composed of a limit frame and two guide wheels. In the process of transmitting the single line, the single line is located between the two guide wheels. The single line is guided by the arc-shaped elastic plate 7 and all the guides 8 thereon, so that the tension control of the single line can be completed in a smooth transition, which effectively alleviates the metal fatigue problem caused by frequent bending. The connecting frame 6 is provided with a control component for controlling the deformation state of adjacent arc-shaped elastic plates 7.

[0021] like Figure 6 As shown, the control assembly includes a second driving member 9 fixed to the connecting frame 6. The second driving member 9 can be an electric push rod or a hydraulic push rod. The telescopic end of the second driving member 9 is fixed with a sliding plate 10. The sliding plate 10 is hinged to two hinged rods 11. The two hinged rods 11 are respectively hinged to the two ends of the adjacent arc-shaped elastic plate 7. The sliding plate 10 pulls the two ends of the arc-shaped elastic plate 7 through the two hinged rods 11 to control the bending degree of the arc-shaped elastic plate 7.

[0022] like Figure 6-Figure 8 As shown, a limiting plate 12 is fixed to the side of the arc-shaped elastic plate 7 close to the adjacent sliding plate 10, which is a mirror image and evenly distributed along the edge line of the arc-shaped elastic plate 7. The limiting plate 12 is not in contact with the arc-shaped elastic plate 7 on the side away from the side fixed to the arc-shaped elastic plate 7. When the arc-shaped elastic plate 7 is bent to a straight state, the limiting plate 12 contacts the limiting plate 12 adjacent to and close to the middle of the arc-shaped elastic plate 7. The limiting plate 12 is in contact with the arc-shaped elastic plate 7 on the side away from the side fixed to the arc-shaped elastic plate 7. The limiting plate 12 is used to support the arc-shaped elastic plate 7 so that the arc-shaped elastic plate 7 gradually changes from a bent state to a straight state.

[0023] Working principle: When it is necessary to produce fire-resistant wires, the staff first passes a single wire through all the guides 8 on the corresponding arc-shaped elastic plate 7 (from left to right), then passes all the single wires through the guide frame 5, and then connects the right side of all the single wires to the external traction equipment, thereby completing the preparation work before twisting the fire-resistant wires.

[0024] After completing the preparations for twisting the fireproof wires, the staff starts the first driving member 4 and the external traction device through the control terminal. The traction device pulls all the single wires to the right, so that the single wires are gathered into one after passing through the guide frame 5 (this operation process is consistent with the existing twisting process). The first driving member 4 drives the rotating member 3 to rotate synchronously to complete the twisting of the single wires. During the rotation of the rotating member 3, it drives the parts on it to rotate synchronously.

[0025] As the external traction equipment pulls the single wire, the single wire gradually passes through all the guide members 8 on the same arc-shaped elastic plate 7, and is guided by the two guide wheels in the guide members 8. By guiding the single wire by all the guide members 8 on the same arc-shaped elastic plate 7, the bending amplitude of the bending point is reduced, effectively alleviating the metal fatigue problem caused by frequent bending.

[0026] When the staff needs to adjust the tension of the single line according to the finished product (whether the tension of the single line is reduced or increased later, Figure 6 (Based on the state of the parts in the figure), take reducing the tension of a single wire as an example: The control terminal controls the telescopic portion of the second driving member 9 to extend toward the side away from the adjacent connecting frame 6. During the extension process, the telescopic portion of the second driving member 9 drives the adjacent sliding plate 10 to move synchronously. During the movement process, the sliding plate 10 pulls the left and right ends of the adjacent arc-shaped elastic plate 7 through the two hinged rods 11 (the two hinged rods 11 pull the adjacent arc-shaped elastic plate 7 and the adjacent sliding plate 10 to generate relative rotation). The left and right ends of the arc-shaped elastic plate 7 are deformed toward the side close to the adjacent connecting frame 6. During the deformation process of the left and right ends of the arc-shaped elastic plate 7, the limit plate 12 is moved synchronously. When the limit plate 12 is in contact with the limit plate 12 and the arc elastic plate 7 adjacent to and close to the middle of the arc elastic plate 7, the outer side of the arc elastic plate 7 is close to a straight state. As the arc elastic plate 7 continues to bend and cooperates with the support of the arc elastic plate 7 by the limit plate 12, the arc elastic plate 7 gradually changes from the bent state to a straight state. Through the above operation, the effect of reducing the single-line tension is achieved. After the arc elastic plate 7 becomes straight, the telescopic part of the second driving member 9 is controlled by the control terminal to stop moving. When it is necessary to reset the arc elastic plate 7, the telescopic part of the second driving member 9 is controlled to retract by the control terminal. During the retraction process of the telescopic part of the second driving member 9, the arc elastic plate 7 is no longer pulled by the sliding plate 10 and the two adjacent hinged rods 11. At this time, the arc elastic plate 7 is reset by relying on its own elasticity, and the limit plate 12 is reset synchronously with the arc elastic plate 7 and no longer in contact with the arc elastic plate 7. Now take increasing the tension of a single line as an example: the control terminal controls the telescopic part of the second driving member 9 to retract inward, and the telescopic part of the second driving member 9 drives the adjacent sliding plates 10 to move synchronously during the retraction process. During the movement, the sliding plate 10 squeezes the left and right ends of the adjacent arc-shaped elastic plates 7 through the two hinged rods 11, so that the arc-shaped elastic plate 7 drives all the guide members 8 thereon to deform inward, thereby increasing the tension of the single line (after the tension of the single line meets the working requirements, the telescopic part of the second driving member 9 stops moving. When it needs to be reset, the telescopic part of the second driving member 9 extends and pulls the arc-shaped elastic plate 7 to reset through the sliding plate 10 and the two adjacent hinged rods 11). Through the above method combined with the back-and-forth deformation of the arc-shaped elastic plate 7, the single line can complete tension control in a smooth transition, effectively alleviating the metal fatigue problem caused by frequent bending.

[0027] When there is no need to produce fireproof wires anymore or after the production of fireproof wires is completed, the staff can simply turn off all electrical components through the control terminal.

[0028] Example 2: Based on Example 1, Figure 9 and Figure 10As shown, it also includes an emergency treatment component distributed in a ring array and the same number as the arc-shaped elastic plate 7. The emergency treatment components distributed in the ring array are respectively arranged on the corresponding arc-shaped elastic plate 7. The emergency treatment component is used to perform emergency buckling on the single line. The emergency treatment component includes a fixed frame 13, which is arranged on one of the guide members 8 of the corresponding arc-shaped elastic plate 7 (the fixed frame 13 can be installed on any guide member 8 on the arc-shaped elastic plate 7, but in this device, the fixed frame 13 is installed on the guide member 8 located in the middle of the arc-shaped elastic plate 7). The fixed frame 13 is limited to slide and rotate with a sliding ring 14, and a shrinkage ring is fixed between the fixed frame 13 and the sliding ring 14. Part 15, a torsion spring wound around the outside of the contraction part 15 is fixed between the fixed frame 13 and the sliding ring 14, the contraction part 15 can be cotton cloth, the contraction part 15 is loose when it does not wrap the single wire tightly, and the torsion spring on its outside is in a stretched and torsional storage state at this time, the contraction part 15 is in a twisted and contracted state when it wraps the single wire tightly, and the torsion spring on its outside is not in a stretched and torsional storage state at this time, the fixed frame 13 is fixed with an F-shaped frame 16, the sliding ring 14 is provided with limiting holes distributed in a ring array, the F-shaped frame 16 is slidably connected to a spring pin 17 that passes through the fixed frame 13 and is slidably connected thereto, and when the spring pin 17 is inserted into the adjacent limiting hole on the sliding ring 14, the sliding ring 14 is limited.

[0029] like Figure 9 and Figure 11-13 As shown, it also includes a tension monitoring assembly distributed in a ring array and the same number as the arc-shaped elastic plates 7. The tension monitoring assemblies distributed in the ring array are respectively arranged on the corresponding arc-shaped elastic plates 7. The tension monitoring assembly is used to monitor the tension of the single line. The tension monitoring assembly includes an L-shaped frame 18. The L-shaped frame 18 is arranged on the side of the adjacent arc-shaped elastic plate 7 away from the rotating member 3. The L-shaped frame 18 is fixedly connected to a liquid housing 19. Hydraulic oil is stored in the liquid housing 19. The liquid housing 19 consists of two shells and the two are sealed by a sealing gasket. The liquid housing 19 is sealed and slidably connected to a sliding member 20 for guiding the single line. The liquid housing 19 is fixedly connected to the sliding member 20. A first tension spring is fixed to the liquid holding shell 19, and a spring distance sensor 21 is fixed to the liquid holding shell 19. The telescopic end of the spring distance sensor 21 is fixed to the sliding member 20. A driving assembly for controlling the corresponding spring pin 17 is provided on the liquid holding shell 19. When the single line is in a taut state, the sliding member 20 stretches the first tension spring in the liquid holding shell 19. The sliding member 20 is located on the side outside the liquid holding shell 19 and is also provided with two guide wheels for guiding the single line. During the movement, the sliding member 20 drives the telescopic part of the spring distance sensor 21 to move synchronously, so that the spring distance sensor 21 can know the position of the sliding member 20 in time, and reflect the tension of the single line through the position of the sliding member 20.

[0030] like Figure 9 and Figure 11-13As shown, the drive assembly includes a fixed plate 22, which is fixed to the side of the liquid housing 19 away from the spring distance sensor 21. A wire sleeve 23 is fixed between the fixed plate 22 and the adjacent F-shaped frame 16. A wire core 24 is slidably connected in the wire sleeve 23. One end of the wire core 24 is fixed to the spring pin 17. The liquid housing 19 is fixed to the side close to the fixed plate 22 and is connected to a fixed shell 25. The fixed shell 25 consists of two shells and is sealed by a sealing gasket. The inner limit of the fixed shell 25 The sliding frame 26 is connected to the fixed shell 25 in a sealing and sliding manner. One side of the sliding frame 26 is located in the fixed shell 25 and is sealed and slidably connected thereto. The sliding frame 26 is fixedly connected to the other end of the wire core 24. A second tension spring is fixedly connected between the sliding frame 26 and the fixed shell 25. During the movement of the sliding frame 26, the wire core 24 is pulled by the wire core 24, and the wire core 24 pulls the spring pin 17 so that the spring pin 17 no longer limits the sliding ring 14. The inner diameter of the fixed shell 25 is smaller than the inner diameter of the liquid holding shell 19, which is used to amplify the moving stroke of the sliding frame 26.

[0031] like Figure 13 and Figure 14 As shown, the sliding member 20 is located in the liquid holding shell 19 and is slidably connected to a uniformly distributed connecting column 28 on one side. The sliding member 20 is located in the liquid holding shell 19 and is provided with a uniformly distributed liquid through hole on one side. The uniformly distributed connecting column 28 is fixedly connected with a shielding ring 27. The outer diameter of the shielding ring 27 is smaller than the diameter of the side of the sliding member 20 located in the liquid holding shell 19. The shielding ring 27 is used to shield all the liquid through holes on the sliding member 20. A spring is fixed between the shielding ring 27 and the sliding member 20. The liquid holding shell 19 is away from the fixed shell 25. An elastic tympanic membrane 29 is provided on the side. During the normal installation of the single line, the single line will be tightened during the process. Drive the sliding part 20 to move in the liquid storage shell 19. At that time, the hydraulic oil in the liquid storage shell 19 will flow through the liquid hole of the sliding part 20. During this process, the elastic eardrum 29 will not be deformed, and the sliding frame 26 will not move at will under the action of the second tension spring. The shielding ring 27 is provided with a pit, and the second tension spring between the shielding ring 27 and the sliding part 20 is located in the pit of the shielding ring 27. When the shielding ring 27 is in contact with the sliding part 20, the shielding ring 27 blocks the liquid hole of the sliding part 20. The second tension spring between the shielding ring 27 and the sliding part 20 can be located in the pit of the shielding ring 27, which is used to make the shielding ring 27 and the sliding part 20 fit together.

[0032] Working principle: In the process of threading a single wire, the single wire passes through the retractor 15, the middle part of the sliding member 20 away from the adjacent sliding plate 10 (that is, between the two guide wheels), and then passes through the guide frame 5 and is connected to the external traction device. When the external traction device pulls all the single wires, the single wire gradually tightens and drives the sliding member 20 to move toward the side close to the adjacent sliding plate 10. During the movement of the sliding member 20, the first tension spring is pulled, and during the movement of the sliding member 20, the hydraulic oil in the liquid storage shell 19 flows through the liquid hole on the sliding member 20. At this time, since the sliding member 20 is driven and moved by the single wire, the pressure in the liquid storage shell 19 is kept stable through the deformation of the elastic tympanic membrane 29. When the single wire is tightened, the sliding member 20 stops moving.

[0033] During the movement of the sliding member 20 toward the side close to the adjacent sliding plate 10, the telescopic part of the spring distance sensor 21 is squeezed, so that the spring distance sensor 21 monitors the position of the sliding member 20. In the subsequent process of conveying the single line, when the tension of the single line increases, the sliding member 20 squeezes the telescopic part of the spring distance sensor 21. When the tension of the single line decreases, the sliding member 20 pulls the telescopic part of the spring distance sensor 21. Through the above process, the tension of the single line is obtained.

[0034] When the tension of the single line disappears instantaneously (the instantaneous disappearance of the single line tension proves that the single line is broken), the first tension spring in the sliding part 20 pulls the liquid shell 19, causing the sliding part 20 to slide to the side away from the sliding frame 26. During this process, the movement speed of the sliding part 20 is faster than the speed at which the sliding part 20 is driven by the single line during the above-mentioned tension adjustment process. After the blocking ring 27 is blocked by the hydraulic oil in the sliding part 20, the blocking ring 27 and the connecting column 28 are relatively displaced with the sliding part 20 during the movement of the sliding part 20. During the displacement of the blocking ring 27, the spring is squeezed and the liquid hole of the sliding part 20 is blocked.

[0035] After the liquid hole of the slider 20 is blocked, under the action of the first tension spring in the liquid holding shell 19, the slider 20 drives the blocking ring 27 to continue to move to the side away from the fixed shell 25 through the connecting column 28. At this time, the hydraulic oil in the liquid holding shell 19 away from the fixed shell 25 is compressed, causing the elastic tympanic membrane 29 to deform outward, giving the slider 20 an additional displacement stroke. After the slider 20 is displaced, the hydraulic oil in the liquid holding shell 19 close to the fixed shell 25 drives the sliding frame 26 to move to the side close to the slider 20. During the movement of the sliding frame 26, the wire core 24 is pulled and the adjacent second tension spring is pulled. After the wire core 24 is pulled, the spring pin 17 is driven to move upward, so that the spring pin 17 is out of contact with the adjacent limiting hole on the sliding ring 14, thereby releasing the limit of the sliding ring 14. Under the action of the adjacent torsion spring of the sliding ring 14, the sliding ring 14 is driven to move to the side away from the spring pin 17 and twisted and reset. During the reset process of the sliding ring 14, the shrinking part 15 is squeezed and twisted. After the shrinking part 15 is twisted, the single wire is wound and fixed, and the single wire is fixed in a flexible contact manner after the breakage of the single wire, thereby reducing the secondary damage caused by the dispersion of the single wire after the breakage, facilitating subsequent repairs and reducing safety hazards.

[0036] After the tension of the single line disappears instantly, the sliding member 20 drives the telescopic part of the adjacent spring distance sensor 21 to extend rapidly, and then transmits the electrical signal to the control terminal through the spring distance sensor 21, and then transmits it to the first driving member 4 by the control terminal, so that the first driving member 4 no longer drives the rotating member 3 to rotate.

[0037] When the rotating part 3 stops rotating, it is repaired by the staff. During the repair process, the parts on it need to be reset. The reset process is as follows: The staff pushes the sliding member 20 toward the side close to the sliding frame 26, so that the sliding member 20 actively breaks away from the contact with the shielding ring 27 during the movement, so that the shielding ring 27 no longer blocks the liquid hole on the sliding member 20. Under the action of the spring, the shielding ring 27 maintains a gap with the sliding member 20 again (the first tension spring of the sliding member 20 is stretched at this time). At this time, the elastic tympanic membrane 29 is reset, and the sliding frame 26 is reset under the action of the second tension spring and no longer pulls the wire core 24. After the wire core 24 is no longer dragged, the spring pin 17 is reset, and then the staff pulls and rotates the sliding ring 14 in the direction of the spring pin 17, so that the sliding ring 14 not only pulls the contraction member 15 during the movement, but also causes the contraction member 15 to twist, and the contraction member 15 is stretched and reset while twisting; During the movement of the sliding ring 14, the staff first pulls the spring pin 17 to the side away from the retracting part 15. When the sliding ring 14 moves to the point where the center axis of its upper limit hole coincides with the center axis of the spring pin 17, the staff releases the spring pin 17 and inserts the spring pin 17 into the sliding ring 14, thereby completing the resetting of the retracting part 15.
