[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0032] This embodiment of a non-slip cable conveyor relates to the field of cable conveying technology. A transmission belt 210 simultaneously drives two sets of roller units 110, allowing both roller units 110 to drive the cable at the same speed. A ratchet transmission unit 220 is provided between the transmission belt 210 and the roller units 110. When the cable's moving speed exceeds the drive speed of the roller units 110, the ratchet transmission unit 220 rotates relative to the roller units 110, preventing the roller units 110 from slipping relative to the cable.

[0033] See also Figures 1 to 7 In this embodiment, an anti-slip cable conveyor includes: a conveying component 100 and a transmission component 200. The conveying component 100 includes a roller unit 110 and a conveying box 120. The two roller units 110 are arranged in the conveying box 120. A driving space for conveying cables can be formed between the two roller units 110. The roller units 110 can drive the cables to move relative to each other through friction. The two roller units 110 can drive the cables to move at the same speed to avoid a speed difference between the two roller units 110 and the cables, which causes the cables to slip and cause damage to the cables.

[0034] The transmission assembly 200 includes a transmission belt 210 and two ratchet transmission units 220. The two ratchet transmission units 220 are respectively connected to the input ends of the two roller units 110. The transmission belt 210 is sleeved on the two ratchet transmission units 220. The transmission belt 210 can drive the roller units 110 to rotate through the ratchet transmission units 220, thereby driving the cable to feed. The transmission belt 210 has a transmission state and a slip state relative to the input end of the roller units 110. When the moving speed of the cable is less than the driving speed of the roller units 110, it is in the transmission state. The transmission belt 210 can drive the roller units 110 to rotate with the help of the ratchet transmission units 220, so that the rotation speed of the ratchet transmission units 220 is consistent with the rotation speed of the transmission belt 210, thereby driving the cable to move. When the moving speed of the cable is greater than the driving speed of the roller unit 110, it is in a slipping state. The cable can drive the roller unit 110 to rotate relative to each other, so that the input end of the roller unit 110 can rotate relative to the transmission belt 210 with the help of the ratchet transmission unit 220, thereby preventing slippage between the roller and the cable.

[0035] In some embodiments, see Figures 4 to 7 The ratchet drive unit 220 includes an outer ring 221, an inner ring 222, and a ratchet drive member 223. The outer ring 221 is sleeved on the inner ring 222 and is relatively coaxially arranged. The inner ring 222 is connected to the outer ring 221 via the ratchet drive member 223. The ratchet drive member 223 realizes one-way transmission between the outer ring 221 and the inner ring 222. Rotation of the outer ring 221 in one direction can effectively drive the inner ring 222. This same-direction rotation ensures reliable power transmission. In the other direction, the outer ring 221 can rotate freely without applying any resistance to the inner ring 222, avoiding energy waste and unnecessary friction.

[0036] In some embodiments, see Figures 5 to 7 The ratchet transmission element 223 includes a resilient pawl 223a and ratchet teeth 223b. The pawl 223a is disposed on the outside of the inner ring 222 and is rotationally connected to the inner ring 222. The ratchet teeth 223b are disposed on the inside of the outer ring 221 and are fixedly connected to the outer ring 221. The combination of the pawl 223a and the ratchet teeth 223b enables one-way transmission between the two. When the outer ring 221 rotates in the forward direction, the pawl 223a engages the ratchet teeth 223b, thereby driving the inner ring 222 to rotate. When the outer ring 221 rotates in the reverse direction, the pawl 223a can rebound relative to the ratchet teeth 223b, releasing the lock between the pawl 223a and the ratchet teeth 223b.

[0037] During use, when the cable speed exceeds the driving speed of the roller unit 110, the pawl 223a can flexibly disengage from the ratchet 223b, allowing the outer ring 221 to rotate freely relative to the inner ring 222, avoiding slipping and improving stability.

[0038] In some embodiments, see Figure 6 An annular groove 222a is provided on the outer side of the inner ring 222. A pawl 223a is disposed within the annular groove 222a and is rotatably connected to both sides of the inner portion of the annular groove 222a. The structure of the annular groove 222a provides a stable positioning space for the pawl 223a, ensuring that the pawl 223a remains within the predetermined track during rotation, reducing deviation and swing of the pawl 223a and improving transmission accuracy. The rotational connection of the pawl 223a within the annular groove 222a allows for flexible movement during power transmission, enabling the pawl 223a to effectively engage and disengage with the ratchet teeth 223b, ensuring smooth one-way transmission.

[0039] It should be noted that: a rotating shaft is provided on opposite sides of the pawl 223a, the rotating shaft is connected to the annular groove body 222a through a torsion spring, and the two ends of the torsion spring are respectively connected to the pawl 223a and the annular groove body 222a, thereby driving the pawl 223a to rebound relatively.

[0040] In some embodiments, see Figure 5 Multiple ratchet teeth 223b are provided and are equidistantly spaced around the central axis of the outer ring 221. Multiple pawls 223a are provided and are equidistantly spaced around the central axis of the inner ring 222. A pawl 223a is positioned between two adjacent ratchet teeth 223b. The equidistant arrangement of multiple ratchet teeth 223b and pawl 223a ensures more uniform power transmission, avoids localized overload and wear, and improves the efficiency and reliability of the entire system. The pawl 223a is positioned between two adjacent ratchet teeth 223b, allowing the pawl 223a to engage and disengage with the ratchet teeth 223b promptly and effectively, reducing vibration and impact during the engagement process and improving transmission smoothness.

[0041] The arrangement of multiple pawls 223a and ratchet teeth 223b provides a certain degree of redundancy. When a pawl 223a or ratchet tooth 223b is worn or fails, the other pawls 223a can still work normally, thereby ensuring the continuity and reliability of the system.

[0042] In some embodiments, see Figure 4 and Figure 5 The outer side of the outer ring 221 is provided with a tooth groove 221a that cooperates with the transmission belt 210. Multiple tooth grooves 221a are arranged equidistantly around the central axis of the outer ring 221. The cooperation between the tooth groove 221a and the transmission belt 210 can form a tighter engagement, reduce the energy loss during the transmission process, and improve the overall transmission efficiency.

[0043] The tooth grooves 221 a increase the contact area between the transmission belt 210 and the outer ring 221 , thereby enhancing friction, reducing the risk of slipping, and ensuring stable power transmission.

[0044] The equidistantly arranged tooth grooves 221a allow the system to maintain good responsiveness under different speed and load conditions, can effectively adapt to changes in cable speed, and avoid cable wear.

[0045] In practice, the rectangular cross-section design provides a larger contact area, better distributing the pressure applied to the tooth groove 221a, improving load-bearing capacity and adapting to higher load conditions. Compared to other shapes (such as circular or triangular), the rectangular cross-section is less likely to deform under load, helping to maintain the shape stability of the tooth groove 221a, thereby improving the reliability of the entire transmission system.

[0046] A portion of the transmission belt 210 is also sleeved on the servo motor, and the servo motor can drive the transmission belt 210 to rotate through the transmission wheel 112 to provide power for the operation of the cable conveyor.

[0047] In some embodiments, see Figure 1 and Figure 2 The conveying assembly 100 also includes a lifting unit 130. One roller unit 110 is fixedly connected to the conveying box 120, and the other roller unit 110 is connected to the conveying box 120 via the lifting unit 130. The lifting unit 130 can adjust the distance between the two roller units 110. This allows for adjustments based on different cable specifications or different construction requirements, ensuring that the conveying device can adapt to various cable types and diameters, improving applicability.

[0048] By adjusting the distance between the rollers through the lifting unit 130, it is possible to ensure that the cable is supported more evenly during transportation, avoid uneven force on the cable due to improper spacing between the rollers, and thus reduce the risk of cable damage during transportation.

[0049] In some embodiments, see Figure 2 The lifting unit 130 includes a screw 131 and a connecting block 132. The connecting block 132 is connected to the roller unit 110. The screw 131 passes through the conveying box 120 and is threadedly connected to the connecting block 132. The relative rotation of the screw 131 can drive the connecting block 132 to move the roller unit 110. The screw 131 can push the connecting block 132 to move relative to each other and maintain self-locking. The two roller units 110 can move relative to each other, changing the distance between the two rollers, so that the roller assembly can better fit the cable and drive the cable to move.

[0050] In some embodiments, please refer to Figure 2The roller unit 110 includes a connecting frame 111, a plurality of transmission wheels 112 rotatably connected to the connecting frame 111, and a crawler belt 113. The arrangement of the plurality of transmission wheels 112 can achieve more efficient cable feeding. The close fit between the crawler belt 113 and the transmission wheel 112 provides a larger contact area, thereby improving the driving efficiency and the stability of power transmission, and ensuring the smooth advancement of the cable during transportation. The arrangement of the plurality of transmission wheels 112 makes the pressure applied to the cable more uniform, avoiding local damage or wear of the cable due to excessive pressure on a single point, helping to extend the service life of the cable and reducing wear problems caused by friction. The flexible arrangement of the crawler belt 113 can adapt to cables of different diameters and materials, thereby improving the adaptability of the roller unit 110.

[0051] The plurality of transmission wheels 112 are connected to the ratchet transmission unit 220 via a rotating shaft, ensuring effective transmission of power, so that the crawler belt 113 can smoothly drive the cable to feed, thereby improving the working efficiency of the conveying system.

[0052] Workflow: Pass the cable through the driving space between the two roller units 110, and rotate the screw 131 so that the roller unit 110 moves relative to the other roller unit 110 and presses the cable. Start the servo motor to drive the transmission belt 210 to drive the roller unit 110 to rotate. When the moving speed of the cable is less than the driving speed of the roller unit 110, the transmission belt 210 can drive the roller unit 110 to rotate with the help of the ratchet transmission unit 220, so that the rotation speed of the ratchet transmission unit 220 is consistent with the rotation speed of the transmission belt 210, driving the cable to move. When the moving speed of the cable is greater than the driving speed of the roller unit 110, the cable can drive the roller unit 110 to rotate relative to it, so that the input end of the roller unit 110 can rotate relative to the transmission belt 210 with the help of the ratchet transmission unit 220, thereby preventing slippage between the roller and the cable.

[0053] The above description is only a preferred specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the present invention.
