[0006] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The end of the cable is passed through the follower cable laying mechanism (3) and installed on the diameter-changing assembly; when the cable is wound up and unwound, the winding and unwound assembly will control the diameter-changing assembly to rotate in a clockwise or counterclockwise direction, and the winding and unwound assembly will also control the follower cable laying mechanism (3) to move back and forth along the front and back direction of the control base (1) during the cable winding and unwound process, so as to continuously guide the cable; in addition, the follower cable laying mechanism (3) will also control the transverse pressure component to move back and forth along the front and back direction of the control base (1) together with the follower cable laying mechanism (3) through the linkage component and continuously provide leftward pressure to the cable, so that the outer ring cable is close to the inner ring cable or the outer end of the diameter-changing assembly; 2. When the device performs cable winding operations, after the inner coil of cable on the reducing assembly is wound, the transverse pressing assembly will automatically retract a distance to the right, the retraction distance being the same as the outer diameter of the cable. This allows the inner coil of cable to be repositioned and the outer coil of cable to be pressed. This enables the device to automatically change the position of the transverse pressing assembly according to the number of cable winding turns, thus providing continuous pressure on the cable during winding. Similarly, when the device performs cable unwinding operations, the transverse pressing assembly will automatically move to the left according to the number of cable unwinding turns, allowing the device to also provide continuous pressure on the cable during unwinding. During the winding process, a continuous clamping force is provided to the cable. In this way, the probability of loosening during cable winding and unwinding is reduced, thereby improving the quality of cable winding and unwinding. Furthermore, during the cable winding and unwinding process, the tension control component also controls the outward expansion of the diameter reducing component according to the number of turns of the cable winding and unwinding, providing outward expansion tension to the inner ring of the cable on the diameter reducing component, ensuring that the inner ring of the cable is tightly attached to the outer ring of the cable, avoiding insufficient cable tension during winding and unwinding, which could cause the inner ring of the cable to slip. In conjunction with the transverse pressing component, a clamping force is provided to both the inner and outer rings of the cable roll, further improving the quality of cable winding and unwinding. 3. When the take-up and unwinding assembly controls the diameter-changing assembly to take up and unwind the cable, the bidirectional check mechanism (5) can automatically adjust the connection relationship with the take-up and unwinding assembly according to the take-up and unwinding status of the device, and block the take-up and unwinding assembly from rotating. This prevents the cable from falling or sliding down on its own when the cable itself, the external traction load, or the take-up and unwinding assembly fails. This achieves automatic braking during the cable take-up and unwinding process and improves the safety during the take-up and unwinding process. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9A self-buffered braking cable winch includes a control base 1, and also includes a tension adaptive adjustment take-up and unwinding mechanism 2, a follow-up wire laying mechanism 3, a follow-up wire pressing mechanism 4, and a bidirectional check mechanism 5. The tension adaptive adjustment take-up and unwind mechanism 2, which provides tension to the inner coil of the cable during the take-up and unwinding process, is installed on the front and rear sides of the control base 1. The tension adaptive adjustment take-up and release mechanism 2 includes a take-up and release assembly, a diameter adjustment assembly, and a tension control assembly; the take-up and release assembly is installed on the front and rear sides of the control base 1; the diameter adjustment assembly is connected to the front and rear take-up and release assemblies; the tension control assembly is installed on the rear side of the diameter adjustment assembly. The follow-up cable laying mechanism 3, which provides limit guidance for the cable, is connected to the control base 1 and the cable take-up and unwinding assembly. The follow-up wire pressing mechanism 4, used to continuously press the cable to achieve tight wire winding, is installed on the right side of the control base 1 and connected to the follow-up wire laying mechanism 3. The follow-up wire pressing mechanism 4 includes a linkage component and a transverse wire pressing component; the linkage component is connected to the control base 1 and the follow-up wire laying mechanism 3; the transverse wire pressing component is connected to the linkage component; A bidirectional anti-reverse mechanism 5, used to prevent the take-up or unwinding assembly from reversing during take-up or unwinding, is installed on the front and rear sides of the control base 1 and connected to the take-up or unwinding assembly. In this invention, the end of the cable is passed through the follower cable laying mechanism 3 and installed on the diameter-changing assembly. When the cable is wound up or unwound, the winding and unwound assembly controls the diameter-changing assembly to rotate in a clockwise or counterclockwise direction. The operation of the winding and unwound assembly also controls the follower cable laying mechanism 3 to move back and forth along the front and back direction of the control base 1 during the cable winding and unwound process, so as to achieve continuous guidance of the cable. Furthermore, the follow-up cable laying mechanism 3 will also control the transverse pressing component to move back and forth along the control base 1 together with the follow-up cable laying mechanism 3 through the linkage component, and continuously apply leftward pressure to the cable, so that the outer ring cable is tightly attached to the inner ring cable or the outer end of the diameter changing component. When the device performs cable winding operation, after the inner ring of cable on the reducing assembly is wound up, the transverse pressing assembly will automatically retract a distance to the right, and the retraction distance is the same as the outer diameter of the cable. This allows the inner ring of cable to be moved aside and the outer ring of cable to be pressed. This enables the device to automatically change the position of the transverse pressing assembly according to the number of cable winding turns, thereby enabling the device to provide continuous pressing force on the cable during the cable winding process. Similarly, when the device is unwinding the cable, the transverse pressing assembly will automatically move to the left according to the number of unwinding turns of the cable, so that the device can also provide continuous pressing force on the cable during the unwinding process. By using the above methods, the probability of loosening during cable winding and unwinding is reduced, thereby improving the quality of cable winding and unwinding. Furthermore, during the cable winding and unwinding process, the tension control component will also control the expansion of the diameter reducing component outward according to the number of turns of the cable winding and unwinding, providing outward expansion tension to the inner coil of the cable on the diameter reducing component, ensuring that the inner coil of the cable is tightly attached to the outer coil of the cable, avoiding insufficient cable tension during the winding and unwinding process, which could cause the inner coil of the cable to slip. In conjunction with the transverse pressing component, it provides pressing force to both the inner and outer coils of the cable roll, further improving the quality of cable winding and unwinding. When the take-up and unwinding assembly controls the diameter-changing assembly to take up and unwind the cable, the bidirectional check mechanism 5 can automatically adjust its connection with the take-up and unwinding assembly according to the take-up and unwinding status of the device, and prevent the take-up and unwinding assembly from rotating. This prevents the cable from falling or sliding rapidly due to the cable's own weight, external traction load, or failure of the take-up and unwinding assembly, thus achieving automatic braking during the cable take-up and unwinding process and improving safety during the take-up and unwinding process.
[0020] Example 2: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, the take-up and unwinding assembly includes a first control motor 21, a drive shaft 22, a driven shaft 23, a conductive slip ring 24, and a separator box 215; the separator box 215 is symmetrically fixedly installed on the front and rear sides of the control base 1; the first control motor 21 is fixedly installed at the front end of the front separator box 215; The drive shaft 22 and the driven shaft 23 are symmetrically rotated and mounted at the front and rear ends of the control base 1; The stator of the conductive slip ring 24 is fixedly installed on the rear inner wall of the control base 1; the mover of the conductive slip ring 24 is fixedly connected to the driven shaft 23. The variable diameter assembly is connected to the drive shaft 22 and the driven shaft 23; The drive shaft 22 is also connected to the follow-up cable laying mechanism 3; The variable diameter assembly includes a limiting baffle 25, a fixed disc 26, a drive gear disc 28, a telescopic support plate 29, a driven roller 213, and an inner support plate 214; the limiting baffle 25 is symmetrically fixedly installed at one end of the drive shaft 22 and the driven shaft 23 that are close to each other; The fixed plate 26 is symmetrically fixedly installed at one end of the front and rear limit baffles 25 that are close to each other; The fixed plate 26 is provided with multiple limiting grooves 27 at equal intervals around its circumference; the telescopic support plate 29 is slidably connected to the limiting grooves 27 for limiting. An inner support plate 214 is fixedly installed between the front and rear limit slides 27; The drive gear 28 is rotatably mounted on the front end of the rear fixed plate 26; the drive gear 28 has multiple drive arc-shaped grooves 210 evenly spaced around its circumference; The distance from one outer end of the driving arc groove 210 to the center point of the driving gear disk 28 is greater than the distance from one inner end of the driving arc groove 210 to the center point of the driving gear disk 28. Driven roller 213 is rotatably mounted at the front end of the rear drive arc groove 210; and driven roller 213 is slidably connected to the inner wall of drive arc groove 210. The tension control assembly is connected to the rear fixing plate 26; The tension control assembly includes a second control motor 211 and a drive gear 212; the second control motor 211 is fixedly mounted on the front end of the rear fixed plate 26; the drive gear 212 is rotatably mounted on the front end of the rear fixed plate 26; the output end of the second control motor 211 is fixedly connected to the drive gear 212; the drive gear 212 is meshed with the drive gear plate 28. The follow-up cable laying mechanism 3 includes a first synchronous transmission assembly 31, a first reciprocating lead screw 32, a first transverse guide rod 33, a cable laying plate 34, and a limiting guide wheel 35; the first synchronous transmission assembly 31 is mounted on the control base 1 and connected to the drive shaft 22; The first synchronous transmission assembly 31 may be a synchronous chain and synchronous sprocket transmission assembly; one synchronous sprocket in the first synchronous transmission assembly 31 is fixedly connected to the drive shaft 22; the other synchronous sprocket in the first synchronous transmission assembly 31 is fixedly connected to the first reciprocating lead screw 32; The first synchronous transmission assembly 31 enables the drive shaft 22 to be connected to the first reciprocating lead screw 32. The front and rear ends of the first reciprocating lead screw 32 are rotatably connected to the front and rear sides of the control base 1; The front and rear sides of the first transverse guide rod 33 are fixedly connected to the front and rear sides of the control base 1. The inner wall of the cable board 34 is slidably connected to the threaded groove on the first reciprocating lead screw 32 via a rotatably connected slider. Furthermore, the ribbon cable board 34 is slidably connected to the first transverse guide rod 33; Two limiting guide wheels 35 are rotatably mounted on the upper side of the cable tray 34; and the two limiting guide wheels 35 are staggered vertically; the limiting guide wheels 35 are provided with grooves for limiting the cable. In this invention, the end of the cable is passed through the staggered limiting guide wheels 35 and installed on the inner support plate 214; when the cable is wound up or unwound, the first control motor 21 controls the drive shaft 22 to rotate, and the drive shaft 22 drives the front limiting baffle 25 to rotate. At this time, the front limiting baffle 25 will drive the rear limiting baffle 25 and the driven shaft 23 to rotate synchronously with the front limiting baffle 25 in a clockwise or counterclockwise direction through multiple inner support plates 214. Furthermore, the rotation of the drive shaft 22 will also drive the first reciprocating screw 32 to rotate through the first synchronous transmission assembly 31, so that the cable tray 34 drives the limit guide wheel 35 to move back and forth along the first transverse guide rod 33, thereby achieving continuous guidance during the cable winding and unwinding process. Furthermore, during the cable winding and unwinding process, the second control motor 211 controls the drive gear 212 to rotate, which in turn drives the drive gear disc 28 to rotate. At this time, the driven roller 213 slides along the drive arc groove 210, causing the telescopic support plate 29 to move outward along the limit slide groove 27 away from the center of the limit baffle 25. This causes the inner support plate 214 to expand outward and provides outward tension to the cable in the inner ring of the inner support plate 214, ensuring that the inner ring cable and the outer ring cable are tightly attached. This avoids insufficient cable tension during winding and unwinding, which could cause the inner ring cable to slip. In conjunction with the transverse pressure assembly, it provides pressure to both the inner and outer rings of the cable roll, further improving the quality of cable winding and unwinding.
[0021] The linkage assembly includes a second synchronous transmission assembly 41, a second reciprocating lead screw 42, a second transverse guide rod 43, and a pressure plate 44; the second synchronous transmission assembly 41 is installed on the rear inner wall of the control base 1 and connected to the first reciprocating lead screw 32. The second synchronous transmission assembly 41 may also be a synchronous chain and synchronous sprocket transmission assembly; one synchronous sprocket in the second synchronous transmission assembly 41 is fixedly connected to the first reciprocating lead screw 32; the other synchronous sprocket in the second synchronous transmission assembly 41 is fixedly connected to the second reciprocating lead screw 42; The first reciprocating lead screw 32 and the second reciprocating lead screw 42 are connected by the second synchronous transmission assembly 41. The front and rear ends of the second reciprocating lead screw 42 are rotatably mounted on the front and rear sides of the control base 1; the front and rear ends of the second transverse guide rod 43 are fixedly mounted on the front and rear sides of the control base 1. The inner wall of the pressure plate 44 is slidably connected to the threaded groove on the second reciprocating screw 42 via a rotatably connected slider. The pressure plate 44 is slidably connected to the second transverse guide rod 43; The transverse pressure wire assembly is connected to the pressure wire plate 44; The transverse pressing assembly includes a servo electric push cylinder 45, a mounting plate 46, and a pressing roller 47; the servo electric push cylinder 45 is fixedly installed on the upper end of the pressing plate 44; the mounting plate 46 is fixedly connected to the output end of the servo electric push cylinder 45; the pressing roller 47 is rotatably installed on the left end of the mounting plate 46. A pressure sensor (not shown in the figure) is fixedly installed on the pressure roller 47. A central control unit (not shown in the figure) is fixedly installed on the control base 1; the central control unit is communicatively connected to the pressure sensor; the central control unit is electrically connected to the servo electric push cylinder 45. In this invention, while the drive shaft 22 drives the first reciprocating screw 32 to rotate through the first synchronous transmission assembly 31, the first reciprocating screw 32 also drives the second reciprocating screw 42 to rotate synchronously through the second synchronous transmission assembly 41. This causes the pressure plate 44 to drive the pressure roller 47 to move back and forth along the control base 1 together with the limit guide roller 35 and continuously provide leftward pressure to the cable, preventing the cable from moving to the right, thereby making the outer ring cable close to the inner ring cable or the outer end of the inner support plate 214. Because the pressure roller 47 is equipped with a pressure sensor, when the reading of the pressure sensor is within the set range, the pressure roller 47 maintains its current position. When the inner coil of cable is wound up and the outer coil of cable begins to be wound up, the reading of the pressure sensor exceeds the set range. At this time, the pressure sensor will transmit a signal to the central control unit, which will then control the servo electric push cylinder 45 to work. The servo electric push cylinder 45 pulls the pressure roller 47 back a certain distance to the right until the reading of the pressure sensor returns to the set range and the back distance is the same as the outer diameter of the cable. Then the servo electric push cylinder 45 stops working, thereby relocking the position of the pressure roller 47, thus making way for the inner coil of cable and pressing the outer coil of cable. This allows the device to automatically change the position of the pressure roller 47 according to the number of cable winding turns, thereby enabling the device to provide continuous clamping force to the cable during the cable winding process.
[0022] Example 3: In some embodiments, such as Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, the bidirectional check mechanism 5 includes a follower ratchet 51, a check pawl 52, a mounting shaft 53, a reset torsion spring 54, a separation shaft 55, and a third control motor 56; the follower ratchet 51 is symmetrically rotated and mounted on the front and rear sides of the control base 1; and the front and rear follower ratchet 51 are respectively fixedly connected to the drive shaft 22 and the driven shaft 23. The teeth of the two follower ratchet 51 are in opposite directions; The separation shaft 55 is obliquely symmetrically mounted on the front and rear sides of the control base 1; the mounting shaft 53 is rotatably mounted on the ends of the front and rear separation shafts 55 that are far apart; a reset torsion spring 54 is wound around the outer end of the mounting shaft 53; one end of the reset torsion spring 54 is fixedly connected to the mounting shaft 53; the other end of the reset torsion spring 54 is fixedly connected to the separation shaft 55. By using the reset torsion spring 54, the mounting shaft 53 always tends to rotate downwards. The anti-return pawl 52 is fixedly installed on the outer end of the mounting shaft 53; the anti-return pawl 52 is engaged with the follower ratchet 51. The third control motor 56 is obliquely and symmetrically fixedly installed on the front and rear sides of the control base 1; the output end of the third control motor 56 is fixedly connected to the separation shaft 55; In this invention, when the first control motor 21 controls the inner support plate 214 to perform a cable winding operation, the front third control motor 56 controls the separation shaft 55 to rotate, causing the front anti-return pawl 52 to separate from the front follower ratchet 51. At this time, when the drive shaft 22 and the driven shaft 23 rotate synchronously in the clockwise direction, they will control the rear follower ratchet 51 to rotate synchronously. The rotation of the follower ratchet 51 will continuously raise the rear anti-return pawl 52 and compress the rear reset torsion spring 54. Whenever the follower ratchet 51 rotates a certain angle, the reset torsion spring 54 returns to its original position, causing the anti-return pawl 52 to reset, so that the anti-return pawl 52 re-engages with the follower ratchet 51, preventing the driven shaft 23 and the drive shaft 22 from rotating in the counterclockwise direction. Similarly, when the first control motor 21 controls the inner support plate 214 to unwind the cable, the drive shaft 22 and the driven shaft 23 rotate synchronously in the counterclockwise direction, and the rear third control motor 56 controls the separation shaft 55 to rotate, so that the rear anti-return pawl 52 separates from the rear follower ratchet 51. At this time, the front follower ratchet 51 and the anti-return pawl 52 cooperate to prevent the driven shaft 23 and the drive shaft 22 from rotating in the clockwise direction. This avoids the cable from falling or slipping rapidly due to the cable's own weight, external traction load, or failure of the first control motor 21, thus achieving automatic braking during the cable winding and unwinding process and improving the safety of the winding and unwinding process.
