Description

Technical Field

[0001] This invention belongs to the field of main cable wrapping tape technology, specifically relating to a DC electric self-rotating wrapping device. Background Technology

[0002] Wrapping the main cables of suspension bridges with protective tape is one of the protective construction methods for the main cables. The wrapping tape is a special polymer material designed for corrosion protection of the main cables of suspension bridges. It can be combined with a dry air dehumidification system to form a comprehensive dehumidification solution for the main cables, providing more effective corrosion prevention and protection for the suspension bridge cable system. Specialized wrapping equipment is used to spirally wind the tape material around the outer layer of the bridge's main cable. Then, a specialized heating device is used to heat-melt and vulcanize the superimposed wrapping tape into a single unit, thus forming a closed protective barrier on the outermost layer of the main cable.

[0003] In existing technologies, manual wrapping of the cable is commonly used, which is inefficient and prone to quality problems. When using machines for processing, the stability of the equipment operation must be ensured. For example, Chinese patent application number 202322398468.8 discloses an automatic wrapping machine for externally wrapping the main cable of a suspension bridge, including a main frame one, a main frame two, a rotating shaft, and a traveling wrapping device. The main frames one and two are symmetrical structures and can be symmetrically assembled into a whole structure through connectors. The middle of the assembled main frames one and two is provided with a through channel structure for the main cable to pass through. A rotating shaft is rotatably installed in the middle of the main frames one and two, and wrapping tape is installed on the rotating shaft. At least one set of traveling wrapping devices is fixedly installed on the main frames one and two. This device saves labor, eliminating the need for four people to work together on the wrapping. It also ensures a tighter fit between the wrapping tape and the main cable, guaranteeing the uniformity of the wrapping tape and meeting the design requirements for uniform tension. This enhances the sealing ability of the wrapping tape and makes it suitable for main cables of different sizes.

[0004] The above-mentioned solution revealed that the overall weight of the equipment is relatively large, and its rotating wheels are small and concentrated, resulting in insufficient contact area with the main cable. This compromises the stability of the equipment's movement, posing a safety hazard. The equipment uses multiple motors, resulting in a complex transmission structure, high manufacturing and maintenance costs, high power consumption, and a short operating time, requiring frequent charging or battery replacements, impacting project schedules and hindering processing efficiency. Furthermore, the wrapping tape is located inside the main frame, making replacement inconvenient and hindering usability.

[0005] Therefore, it is necessary to research and develop an improved DC electric self-rotating wrapping device to solve the above problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a DC-electric self-rotating wrapping device. By improving the rotating frame and its external drive mechanism, a rotating shaft and belt transmission mechanism are constructed, widening the rollers and distributing them over a large span. This facilitates adjustment of the roller positions and inclinations, ensuring they are tangent to the outer wall of the main cable of the suspension bridge. Through frictional transmission, only one set of dual-shaft drive motors is needed to effectively transmit the rollers at different angles, thus solving the technical problems raised in the prior art.

[0007] The present invention provides the following technical solution: A DC-powered self-rotating wrapping device includes a rotating frame movably sleeved on the outside of the main cable of a suspension bridge. A wrapping tape roll positioning mechanism is installed on the outside of the rotating frame for installing wrapping tape rolls to release the wrapping tape and wrap around the surface of the main cable of the suspension bridge. At least three sets of drive mechanisms are installed on the outside of the rotating frame, and multiple sets of drive mechanisms are arranged in a ring array on the outside of the closed rotating frame. Each drive mechanism has inclined rollers at both ends, and the rollers are tangent to the outer wall of the main cable of the suspension bridge. The rollers in the inclined state cooperate with the main cable of the suspension bridge through frictional transmission, so that the rotating frame rotates around its axis and moves along the central axis of the main cable of the suspension bridge. The drive mechanism includes a mounting frame plate installed on the outside of the rotating frame. A dual-axis drive motor is fixedly connected to the outer side of the rotating frame. The two output shafts of the dual-axis drive motor are synchronously connected to two rotating shafts. Triangular wheel frames are provided on both sides of the bottom of the mounting frame plate. Rollers are rotatably connected to the bottom of the inner side of the triangular wheel frames. Driven drive wheels are coaxially distributed at the center of the roller shaft. A drive wheel is fixedly connected to the end of each of the two rotating shafts away from the dual-axis drive motor. A synchronous drive component is sleeved between the outer sides of adjacent drive wheels and driven drive wheels, and the drive wheels and driven drive wheels are driven and engaged through the synchronous drive component.

A first positioning nut is threaded on the outside of the push rod and at the positions on both sides of the crossbeam and the adjusting pile.

[0011] Preferably, the upright plate has a strip groove, and the outer wall of the upright plate has a scale line corresponding to the position of the strip groove. A pointer is movably mounted on the push rod, and the end of the pointer is slidably fitted inside the strip groove. A second positioning nut is threaded onto the outside of the push rod and located on both sides of the pointer.

[0012] Preferably, a first shaft and a second shaft are rotatably connected on the inner side of the rotating frame and at a position corresponding to the lower part of the mounting frame plate. The end of the mounting frame plate is detachably connected to the first shaft by bolts. An adjusting screw is installed on the second shaft. A first spring is sleeved on the outer side of the adjusting screw and between the second shaft and the mounting frame plate. An adjusting groove is opened on the surface of the mounting frame plate to slide with the adjusting screw. A second locking nut is threaded on the outer side of the adjusting screw and at a position above the mounting frame plate.

[0013] Preferably, the packaging tape roll positioning mechanism includes a shelf rod and a side stop located outside the shelf rod. Fixed bases are installed on both sides of the rotating frame. A first card seat and a second card seat are respectively installed at the output ends of the two fixed bases. One end of the shelf rod is hinged to the first card seat, and the other end of the shelf rod is embedded in the U-shaped groove of the second card seat. A through hole is provided on the side of the second card seat, and a plug for locking the shelf rod is inserted into the through hole.

[0014] Preferably, the shelf rod is provided with a clamping assembly, which includes a clamping plate, a second spring member and a third locking nut. The clamping plate, the second spring member and the third locking nut are arranged sequentially end to end along the axial direction of the shelf rod.

[0015] Preferably, the shelf rod is provided with an inner expansion assembly, which includes a roller. The roller is rotatably connected to the outside of the shelf rod, and the surface of the roller has multiple strip holes arranged in a ring array.

[0017] Preferably, multiple ribs are fixedly connected to the inner sides of both the first and second semi-ring frames, and the connection end of the dual-shaft drive motor is electrically connected to a battery. The multiple batteries are arranged in a ring array on the closed rotating frame and are detachably installed with the ribs.

[0018] Compared with the prior art, the present invention has the following advantages: By improving the rotating frame and its external drive mechanism, and constructing rotating shafts and belt or chain transmission mechanisms, the rollers are widened and distributed over a large span, facilitating the adjustment of roller position and inclination to ensure tangency with the outer wall of the suspension bridge's main cable. Through frictional transmission, a single set of dual-shaft drive motors can effectively transmit power to the rollers at different angles without affecting angle adjustment. This allows the rollers to rotate on the outside of the main cable, while the rotating frame rotates around its axis and moves along the central axis of the main cable. The wrapping tape mechanism releases the wrapping tape and winds it around the outside of the main cable, forming a protective wrapping layer. Compared to existing technologies, this method transmits power more effectively, saves energy and is environmentally friendly, frees up manual labor, and provides more stable, uniform, and controllable wrapping and overlapping. The wrapping tension is also more stable, improving the equipment's adaptability to complex environments and ensuring stable operation under various conditions.

[0019] Driven by a set of dual-axis drive motors and powered by DC, the dual-axis drive motors provide more stable operating power. The number of motors is reduced, and the battery and rotating frame are designed to be thinner and lighter, which reduces the overall weight of the equipment. This not only reduces manufacturing and maintenance costs, but also reduces energy consumption, significantly improving the equipment's battery life and further enhancing its processing efficiency.

[0020] By optimizing the tape roll material positioning mechanism and setting it to an external type, the tape roll is sleeved outside the storage rack rod. Further, in conjunction with the side stops and clamping components, the tape roll is axially locked, enabling rapid tape roll replacement and improved operational stability. The entire process is convenient and quick, unaffected by the rotating frame, limiting axial sliding of the tape roll, improving stability during winding, and enhancing wrapping quality. Furthermore, the height adjustment mechanism of the drive mechanism allows for position and angle adjustment of multiple rollers, making operation convenient, greatly improving practicality, and facilitating widespread application.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can refer to a detachable connection: it can be a mechanical connection; it can also be an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] like Figures 1-9 The diagram illustrates a DC-electric self-rotating wrapping device. This device includes a rotating frame 2 movably sleeved on the outside of the main cable 1 of a suspension bridge. A wrapping tape roll positioning mechanism 3 is installed on the outside of the rotating frame 2 for mounting the wrapping tape roll to release the wrapping tape and wrap it around the surface of the main cable 1. At least three sets of drive mechanisms are installed on the outside of the rotating frame 2, arranged in a circular array on the outside of the closed rotating frame 2. Each drive mechanism has adjustable rollers 4 at both ends, and the rollers 4 are tangential to the outer wall of the main cable 1. In an inclined state, the rollers 4, through frictional transmission, work with the main cable 1 to cause the rotating frame 2 to rotate around its axis while moving along the central axis of the main cable 1. The rollers 4 use widened tires, a design that further enhances the stability of the device, increasing the contact surface for more effective power transmission. This not only improves the adaptability of the device in complex environments but also ensures stable operation under different ground conditions.

[0040] The drive mechanism includes a mounting frame plate 5 installed on the outside of the rotating frame 2. A dual-axis drive motor 6 is fixedly connected to the outer side of the rotating frame 2. The two output shafts of the dual-axis drive motor 6 are synchronously connected to two rotatable rotating shafts 7. Triangular wheel frames 8 are provided on both sides of the bottom of the mounting frame plate 5. Rollers 4 are rotatably connected to the bottom inner side of the triangular wheel frames 8. Driven drive wheels 9 are coaxially distributed at the center of the roller 4. The ends of the two rotating shafts 7 away from the dual-axis drive motor 6 are fixedly connected to active drive wheels 10. A synchronous drive component 11 is sleeved between the outer sides of adjacent active drive wheels 10 and driven drive wheels 9, and the active drive wheels 10 and driven drive wheels 9 are driven by the synchronous drive component 11. Optionally, the dual-axis drive motor 6 is a high-quality brushless geared motor with a power of 250W. This type of motor has the advantages of high efficiency, energy saving, and low noise, and can provide stable power output for the equipment. In the embodiment provided in this application, the number of drive mechanisms is two sets. The equipment adopts a three-point positioning and adjustment drive method, which can ensure the stability and accuracy of the equipment during operation. By adjusting the three positioning points, the direction and speed of the equipment can be better controlled, reducing operational deviations and thus improving the quality and precision of product processing.

[0041] In this application, the synchronous drive component 11 adopts a belt or a chain. When a belt drive is adopted, both the driving drive wheel 10 and the driven drive wheel 9 adopt transmission wheels that are matched with the belt; when a chain is adopted, both the driving drive wheel 10 and the driven drive wheel 9 adopt sprockets that are matched with the chain.

[0042] The equipment is installed on the outside of the main cable 1 of the suspension bridge. As needed, a certain number of wrapping tape reel positions 3 are installed. Wrapping tape reels are installed on the wrapping tape reel positions 3. The position and inclination of the rollers 4 are adjusted so that they are tangent to the outer wall of the main cable 1 of the suspension bridge. They are connected by friction transmission. The dual-shaft drive motor 6 is controlled to work. The two output shafts are synchronously connected to two rotatable rotating shafts 7. This transmission structure can meet the effective transmission of the rollers 4 at different angles without affecting the flexible adjustment of the rollers 4. The widened and spaced rollers 4 rotate on the outside of the main cable 1 of the suspension bridge, so that the rotating frame 2 rotates around the axis and moves along the central axis of the main cable 1 of the suspension bridge. At the same time, the end of the wrapping tape is connected to the main cable 1 of the suspension bridge. As the equipment moves on the main cable 1 of the suspension bridge, the wrapping tape is continuously released and wound around the outside of the main cable 1 of the suspension bridge to form a protective wrapping layer.

[0043] Specifically, in the embodiments provided in this application, the rotating speed of the equipment is 3 m / min. This speed determines the processing rhythm of the products on the equipment and has a direct impact on production efficiency. In actual production, this speed needs to be adjusted reasonably according to the overall production rhythm to ensure the efficient operation of the entire production process. At the same time, better processing results can be achieved by adjusting the tilt angle of roller 4. The tilt angle of roller 4 can be adjusted according to the processing requirements of different products to adapt to diverse production processes.

[0044] Furthermore, in the above scheme, the rotating shaft 7 includes a long shaft 701, a short shaft 702, and a universal joint 703. The long shaft 701 and the short shaft 702 are connected and driven by the universal joint 703. A first bracket 704 and a second bracket 705 are mounted on the mounting frame 5, and the first bracket 704 and the second bracket 705 are respectively sleeved on the outside of the long shaft 701 and the short shaft 702. The long shaft 701 and the first bracket 704 are rotatably connected by a rolling bearing, and the short shaft 702 and the second bracket 705 are movably connected by a fisheye bearing. While the long shaft 701 and the short shaft 702 are effectively driven by the universal joint 703, the short shaft 702 can flexibly turn. Specifically, the cooperation between the first bracket 704 and the rolling bearing enables the long shaft 701 to rotate stably around its central axis; the cooperation between the second bracket 705 and the fisheye bearing enables the short shaft 702 to rotate around its central axis, while the angle can be adjusted within the second bracket 705 to adapt to the tilt angle of the roller 4.

[0045] Furthermore, in the above scheme, a positioning shaft bolt 12 is movably connected between the top center of the triangular wheel frame 8 and the mounting frame plate 5. A limit adjustment bolt 13 is movably provided at one end of the triangular wheel frame 8, and an adjustment post 14 is provided at the other end. The top of the triangular wheel frame 8 is in contact with the lower surface of the mounting frame plate 5 and is rotatably engaged by the positioning shaft bolt 12. An arc-shaped limit groove 15 is provided on the surface of the mounting frame plate 5, and the limit bolt 13 slides within the arc-shaped limit groove 15. With the engagement of the arc-shaped limit groove 15, the tilt angle adjustment range of the roller 4 is 0 to ±10°. A first locking nut 16 is threaded onto the outside of the limit bolt 13 and located above the mounting frame plate 5. Screwing the first locking nut 16 in and pressing it against the surface of the mounting frame plate 5 can improve the stability of the roller 4 during operation.

[0046] A push rod 17 connects two opposing adjusting piles 14. The combination of the adjusting piles 14 and the push rod 17 allows them to move parallel to the mounting frame 5. Adjusting the limiting bolts 13 adjusts the tilt direction of the rollers 4, ensuring that the rollers 4 at both ends of the same drive mechanism are parallel and that the tilt angles of multiple rollers 4 are equal to those of the rotating frame 2. This changes the direction of rotation of the wrapping machine (adjusting the travel speed).

[0047] Furthermore, in the above scheme, a vertical plate 18 is integrally provided on the top of the side of the mounting frame 5 near the push rod 17, and a crossbeam frame 19 is fixedly connected to one side of the vertical plate 18. The push rod 17 passes through the crossbeam frame 19 and the adjusting piles 14 on both sides, and slides with the through hole. The through hole on the crossbeam frame 19 is set in a long strip shape. First positioning nuts 20 are threadedly sleeved on the outside of the push rod 17 and on both sides of the crossbeam frame 19 and the adjusting piles 14. Since the through hole on the crossbeam frame 19 is set in a long strip shape, and the adjusting piles 14 and the ends of the triangular wheel frame 8 are movably set (such as rotatably connected), the triangular wheel frames 8 on both sides can move synchronously when the push rod 17 moves, changing the tilt angle of the triangular wheel frame 8 and its internal rollers 4.

[0048] Furthermore, in the above scheme, a strip groove 21 is provided on the upright plate 18, and a scale line is provided on the outer wall of the upright plate 18 at the position corresponding to the strip groove 21. A pointer 22 is movably provided on the push rod 17, and the end of the pointer 22 is slidably fitted inside the strip groove 21. A second positioning nut 23 is threadedly sleeved on the outside of the push rod 17 at the position on both sides of the pointer 22.

[0049] Furthermore, in the above scheme, a first shaft 24 and a second shaft 25 are rotatably connected to the inner side of the rotating frame 2 and at the position corresponding to the lower part of the mounting frame plate 5. The end of the mounting frame plate 5 is detachably connected to the first shaft 24 by bolts. An adjusting screw 26 is installed on the second shaft 25. A first spring 27 is sleeved on the outer side of the adjusting screw 26 and located between the second shaft 25 and the mounting frame plate 5. An adjusting groove 28 is opened on the surface of the mounting frame plate 5 to slide with the adjusting screw 26. A second locking nut 29 is threaded on the outer side of the adjusting screw 26 and located above the mounting frame plate 5. The adjusting groove 28 is set in a long strip shape, so that the mounting frame plate 5 can change its tilt angle. That is, the mounting frame plate 5 can be rotated and adjusted at a certain angle along the direction perpendicular to the main cable, which further changes the distance between the multiple rollers 4 and the axis of the rotating frame 2, thereby changing the cable gripping diameter of the winding machine.

[0050] Furthermore, in the above scheme, the tape roll material position mechanism 3 includes a shelf rod 301 and a side stop 302 located outside the shelf rod 301; both sides of the rotating frame 2 are equipped with fixed bases 30, and the output ends of the two fixed bases 30 are respectively equipped with a first card seat 31 and a second card seat 32, wherein one end of the shelf rod 301 is hinged to the first card seat 31, the other end of the shelf rod 301 is embedded in the U-shaped groove of the second card seat 32, and the side of the second card seat 32 has a through hole 33, and a plug for locking the shelf rod 301 is inserted into the through hole 33. Pull the shelf rod 301 out of the U-shaped groove and rotate it to make the shelf rod 301 stand up. Then, put the tape roll on the outside of the shelf rod 301. Further cooperate with the side stop 302 and the clamping component 303 to lock the tape roll axially. Finally, reset the shelf rod 301 and use the plug to lock the shelf rod 301 to realize the quick replacement of the tape roll. The whole process is convenient and quick and is not affected by the rotating frame.

[0051] As an optional embodiment of the tape roll material positioning mechanism 3 in this application, embodiment one is designed. For example... Figure 12 and Figure 13 As shown, the tape roll positioning mechanism 3 includes a shelf rod 301 for mounting the tape roll. A side stop 302 is rotatably connected to the end of the shelf rod 301. A clamping assembly 303 is movably connected to the outside of the shelf rod 301. The clamping assembly 303 includes a clamping plate 3031, a second spring 3032, and a third locking nut 3033. The clamping plate 3031 is slidably sleeved on the outside of the shelf rod 301, and the third locking nut 3033 is threaded onto the outside of the shelf rod 301. The second spring 3032 is located between the clamping plate 3031 and the third locking nut 3033. When the tape roll is mounted on the outside of the shelf rod 301, one side of the roll is in contact with the side stop 302, and the other side is in contact with the clamping plate 3031. With the cooperation of the third locking nut 3033 and the second spring 3032, the roll is stably positioned, allowing it to rotate around its axis and thus releasing the tape winding. At the same time, it restricts axial slippage of the roll, improves stability during the winding process, and enhances the wrapping quality.

[0052] As another optional embodiment of the tape roll material positioning mechanism 3 in this application, embodiment two is designed. For example... Figure 14 As shown, an inner expansion assembly 304 is provided on the shelf rod 301. The inner expansion assembly 304 includes a roller cylinder 3041, which is rotatably connected to the outside of the shelf rod 301. The surface of the roller cylinder 3041 has multiple annularly arrayed strip holes, within which inner expansion blocks 3042 are embedded. A telescopic top column is installed inside the roller cylinder 3041, and the output end of the telescopic top column is drively connected to the inner expansion block 3042. The outer wall of the inner expansion block 3042 has a friction surface, which, through the principle of shaft expansion, fixes the paper tube in the middle of the roller.

[0053] The strip roll is fitted onto the outside of the strip roll cylinder 3041. After installation, one side of the strip roll is in contact with the side stop 302. At this time, the telescopic top column inside the strip roll cylinder 3041 is activated synchronously, that is, its output end outputs simultaneously, pushing multiple inner expansion blocks 3042 outward through the strip holes and into contact with the inner wall of the strip roll, stabilizing it. The strip roll can then rotate synchronously with the strip roll cylinder 3041, thereby releasing the wrapped strip. Furthermore, this structure not only restricts axial sliding and radial vibration of the strip roll, but also makes it suitable for use with strip rolls of different inner diameters.

[0054] Furthermore, in the above scheme, such as Figure 10 and Figure 11 As shown, the rotating frame 2 includes a first semi-ring frame 201 and a second semi-ring frame 202. The end of the first semi-ring frame 201 is embedded inside the second semi-ring frame 202, and one end of the first semi-ring frame 201 and the second semi-ring frame 202 are hinged together by a rotating shaft 203. The other end of the first semi-ring frame 201 and the second semi-ring frame 202 are detachably locked by a locking member 204. In the locked state, the cross-sectional shape of the rotating frame 2 is a standard circular ring. In this application, the locking member 204 serves as an opening and closing mechanism and can be a quick-locking mechanism.

[0055] Furthermore, in the above scheme, multiple ribs 205 are fixedly connected to the inner sides of both the first semi-ring frame 201 and the second semi-ring frame 202. The connection end of the dual-axis drive motor 6 is electrically connected to a battery 34. Multiple batteries 34 are arranged in a ring array on the closed rotating frame 2 and are detachably installed with the ribs 205. The equipment can be equipped with high-quality LIFPO4 batteries, with a specification of 20AH*3 sets, providing a total range of approximately 3 hours. This type of battery features high energy density, long cycle life, and good safety performance, providing long-lasting and stable power support for the equipment. The approximately 3-hour range can meet the continuous working requirements for a certain period. In actual use, charging time should be reasonably arranged according to the required working time to ensure the continuous normal operation of the equipment. If the working time is long, solutions such as backup batteries can be considered. The rotating frame 2 is made of aluminum alloy, and both the drive mechanism and the battery 34 adopt a compact structure, making it relatively lightweight.

[0056] As a specific embodiment provided in this application, the rotating frame 2 of the equipment has a structure with a diameter of approximately 1400*720mm, which defines the overall shape of the equipment. The maximum product that can pass through is a suspension bridge main cable with a diameter of 922-1040mm, as shown in the attached figure, which is a suspension bridge main cable with a diameter of 982mm.

[0057] In use, the device is installed on the outside of the main cable 1 of the suspension bridge. A wrapping tape roll is installed on the wrapping tape roll position mechanism 3. The position and inclination of the roller 4 are adjusted so that it is tangent to the outer wall of the main cable 1 of the suspension bridge. Through frictional transmission, the device is controlled to work by a dual-shaft drive motor 6. The two output shafts synchronously drive two rotating shafts 7. This transmission structure can meet the effective transmission of the roller 4 at different angles without affecting the flexible adjustment of the roller 4. The widened and spaced rollers 4 rotate on the outside of the main cable 1 of the suspension bridge, causing the rotating frame 2 to rotate around its axis and move along the central axis of the main cable 1 of the suspension bridge. At the same time, the end of the wrapping tape is connected to the main cable 1 of the suspension bridge. As the device moves on the main cable 1 of the suspension bridge, the wrapping tape is continuously released and wound around the outside of the main cable 1 of the suspension bridge, forming a protective wrapping layer.

[0058] The above are merely specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
