Description

Technical Field

[0001] This invention belongs to the field of container machinery technology, specifically relating to a winch device for a container machinery and a container machinery. Background Technology

[0002] As a timber collection and transportation device, the timber winch is characterized by its large transport capacity and load-bearing capacity. Therefore, it requires sufficient traction, especially when operating on slopes. To address the issue of insufficient traction, a winch device needs to be installed on the winch. The timber loading area is located on the upper surface of the rear frame. To achieve a compact overall structural layout, the winch device can be placed on the rear frame, ensuring that its overall structure is compatible with the rear frame structure. Simultaneously, the winch device's arrangement must ensure that the wire rope is evenly and tightly distributed on the drum during winding and that it is discharged in a reasonable and orderly manner during unwinding, avoiding tangled, detached, or climbing ropes. Furthermore, both during unwinding and winding, the tension of the wire rope must be kept within permissible limits to guarantee the safety of the entire machine operation. There are many existing winch device structures used in different types of complete machines, but no winch device suitable for container transport machines has been found so far. Moreover, most existing winch rope arrangers adopt a purely mechanical structure, which has problems such as poor adaptability to wire rope diameter, poor reliability and severe wear. Due to the lack of an electrical control system, it is impossible to avoid wire rope tangling and maintain constant wire rope tension. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a winch device for a collection and transport machine and a collection and transport machine in general. The winch device is arranged on the rear frame of the collection and transport machine and can perfectly adapt to the structure of the rear frame. At the same time, when the rope is wound up, the wire rope can be evenly and tightly distributed on the drum body. When the rope is unwound, the wire rope can be discharged in a reasonable and orderly manner, which can avoid the phenomena of rope tangling, rope slippage or rope climbing.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, a winch device for a container transport machine is provided, comprising: a drum module for winding a wire rope, mounted on the rear frame of the container transport machine and arranged in series along the longitudinal direction of the rear frame of the container transport machine; a rope guide module for guiding the wire rope to be neatly arranged during the winding process of the drum module; and a tensioning module for providing tension to the wire rope during the winding process of the drum module.

[0006] The above technical solution arranges the drum module, rope arranger module, and tensioning module in series along the longitudinal direction of the rear frame of the container transport machine within the winch frame cavity. This allows the winch device to be placed on the rear frame and perfectly adapts to the structure of the rear frame of the container transport machine. At the same time, during rope winding, the wire rope can be evenly and tightly arranged on the drum body, and during rope unwinding, the wire rope can be discharged in a reasonable and orderly manner, avoiding phenomena such as rope tangling, rope slippage, or rope climbing.

[0007] Furthermore, the drum module includes: a drum body for winding the wire rope; a motor reducer assembly for driving the drum body to rotate, the motor reducer assembly being mounted on the winch frame, the output end of the motor reducer assembly being connected to one end of the drum body; and the other end of the drum body being mounted on the winch frame via a drum mounting shaft assembly.

[0008] The above technical solution provides power to the drum body to wind the wire rope through the motor reducer assembly. When winding the rope, the wire rope can be evenly and tightly arranged on the drum. When exiting the drum, the wire rope can be discharged in a reasonable and orderly manner, which can avoid the phenomena of rope tangling, rope slippage or rope climbing.

[0009] Furthermore, the rope guide module includes: a rope guide frame hinged to the winch frame via a hinge shaft assembly; a guide pulley 1 and a guide pulley 2 installed within the rope guide frame for guiding the direction of the wire rope; and a swing cylinder for driving the rope guide frame to reciprocate around the axis of the hinge shaft assembly; one end of the swing cylinder is hinged to a swing cylinder hinge assembly 1 on the winch frame, and the other end is hinged to a swing cylinder hinge assembly 2 on the rope guide frame.

[0010] The above technical solution achieves a uniform and tight arrangement of the wire rope on the drum body by driving the rope guide frame to reciprocate around the axis of the hinge shaft assembly through a swing cylinder. This perfectly solves the problem that the cavity of the winch frame is limited in space due to its adaptation to the rear frame structure of the transport vehicle, making it unsuitable for large-amplitude movements. At the same time, by setting guide pulleys to change the direction of the wire rope, the cavity space of the winch frame is further adapted, allowing the wire rope to enter and exit the winch frame cavity in an orderly manner. Thus, when the rope is wound up, the wire rope can be evenly and tightly arranged on the drum body, and when the rope is unwound, the wire rope can be discharged in a reasonable and orderly manner, avoiding the phenomena of tangled rope, rope slippage, or rope climbing.

[0011] Furthermore, the steel wire rope wound on the drum body passes through guide pulley one and guide pulley two in sequence, and is led out from the tangential direction of guide pulley two, which coincides with the axis of hinge shaft assembly one.

[0012] The above technical solution, by setting the wire rope to pass through guide pulley one and guide pulley two in sequence, and then leading out from the tangential direction of guide pulley two, with the tangential direction of guide pulley two coinciding with the axis of hinge shaft assembly one, can adapt to the cavity space of the winch frame on the one hand, and ensure that the position and direction of the wire rope exiting the rope on the rope arranger module are constant no matter where the rope arranger module swings, thereby avoiding the phenomena of rope tangling, rope slippage or rope climbing.

[0013] Furthermore, the rope feeder frame is also hinged to the winch frame via a second hinge shaft assembly, the axis of which coincides with that of the first hinge shaft assembly.

[0014] The above technical solution, by setting the second hinge shaft assembly in conjunction with the first hinge shaft assembly, achieves multi-point support for the rope arranger frame, reduces swaying during swinging, and thus improves the stability of the rope arranger module during swinging. The stable swinging of the rope arranger can avoid the phenomena of rope tangling, rope slippage, or rope climbing.

[0015] Furthermore, the second hinge shaft assembly is a hollow shaft, and the steel wire rope is led out from the tangential direction of the second guide pulley and passes through the hollow shaft.

[0016] The above technical solution, by setting the second hinge shaft assembly as a hollow shaft, allows the wire rope to be led out from the tangential direction of the second guide pulley and pass through the hollow shaft. This achieves multi-point support for the rope guide frame, ensuring stable swing, while perfectly adapting to the internal space of the winch frame. It also ensures the stability of the rope output position and direction, avoiding unnecessary wear caused by axial deviation between the wire rope and the second hinge shaft assembly, and preventing rope tangling, detachment, or climbing.

[0017] Furthermore, the second guide pulley is mounted on the rope arranger frame via a pin force sensor assembly for detecting the tension of the wire rope.

[0018] The above technical solution, by setting up a pin-shaft force sensor assembly and installing a guide pulley two on the rope guide frame via the pin-shaft force sensor assembly, on the one hand, makes full use of the internal space of the winch frame to detect the tension of the wire rope; on the other hand, by detecting the tension of the wire rope, it achieves precise control of the wire rope, thereby avoiding phenomena such as rope tangling, rope slippage, or rope climbing.

[0019] Furthermore, the rope arranger module also includes: a control rod hinged to the rope arranger frame for monitoring the direction of the wire rope arrangement, the control rod having an elongated hole for the wire rope to pass through; a proximity switch mounted on the rope arranger frame for monitoring the movement state of the control rod, the rope arranger frame having an elongated hole for mounting the proximity switch; and a control valve for controlling the extension or retraction of the swing cylinder based on the detection result of the proximity switch.

[0020] The above technical solution, by setting up a control rod, proximity switch, and control valve, can automatically control the rope arranger module to move in the direction of the wire rope's arrangement based on the detected swing of the wire rope. This avoids rope tangling, rope slippage, or rope climbing, and the control is flexible and accurate. An elongated hole for the wire rope to pass through is provided on the control rod, and the proximity switch is mounted on the rope arranger frame through the elongated hole, accommodating wire ropes of different diameters and improving the applicability of the wire rope. By adjusting the initial distance between the proximity switch and the control rod, the detection accuracy can be improved, thereby preventing rope tangling, rope slippage, or rope climbing.

[0021] Furthermore, the tensioning module includes: a roller mounted on the winch frame; a cycloidal motor for driving the roller to rotate in the direction of the wire rope's exit; a rope-pressing wheel for pressing the wire rope onto the roller; a tensioning frame for mounting the rope-pressing wheel; and an adjusting bolt for adjusting the distance between the rope-pressing wheel and the roller, wherein the adjusting bolt passes sequentially through the pressure sleeve, the spring, and the tensioning frame before being connected to the winch frame.

[0022] The above technical solution, by setting rollers and pressure rollers to clamp the wire rope, and simultaneously driving the rollers to rotate along the wire rope's exit direction with a cycloidal motor, ensures that the wire rope always maintains a certain tension, thereby preventing rope tangling, slippage, or climbing. By installing pressure rollers on the tensioning frame, and connecting the adjusting bolts to the winch frame after passing through the pressure sleeve, spring, and tensioning frame in sequence, wire ropes of different diameters can be pressed onto the rollers, improving the adaptability of the wire rope. At the same time, it ensures that wire ropes of different diameters receive sufficient tension, thus preventing rope tangling, slippage, or climbing. Furthermore, the tensioning module ensures that the wire rope's exit position and direction are constant.

[0023] In a second aspect, a container machine is provided, the container machine being equipped with the winch device for container machines described in the first aspect.

[0024] The above technical solution, by setting the winch device described in the first aspect on the container, realizes that the winch device is arranged in the cavity of the rear frame. At the same time, when the rope is wound up, the wire rope can be evenly and tightly arranged on the drum, and when the rope is unwound, the wire rope can be discharged in a reasonable and orderly manner, which can avoid the phenomenon of rope tangling, rope slippage or rope climbing; thus, the container has sufficient traction force.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0026] (1) The present invention arranges the drum module, the rope arranger module, and the tensioning module in series along the longitudinal direction of the rear frame of the transport machine in the winch frame cavity. The drum module is used to wind up the wire rope; the rope arranger module is used to guide the wire rope to be neatly arranged on the drum body during the winding process of the drum module; the tensioning module is used to provide tension to the wire rope during the winding process of the drum module. This realizes that the winch device can be arranged on the rear frame of the transport machine and can perfectly adapt to the structure of the rear frame of the transport machine. At the same time, the wire rope can be evenly and tightly arranged on the drum during winding, and the wire rope can be discharged in a reasonable and orderly manner during discharge, which can avoid the phenomena of tangled rope, rope slippage or rope climbing. The cavity space of the rear frame is fully utilized, the space utilization rate is high, and the overall structure is compact.

[0027] (2) The rope arrangement control process of the present invention is precise and efficient, so that the wire rope is evenly and tightly arranged on the drum. The wire rope is relatively stable during the reversal process, reducing the probability of rope tangling, rope slippage or rope climbing.

[0028] (3) The present invention maintains constant tension by measuring the tension of the wire rope in real time and adjusting it through the automatic synchronous hydraulic system of the winch, thus ensuring the safety of the whole machine operation;

[0029] (4) The proximity switch of the present invention has an adjustable installation position and strong adaptability to different working conditions and wire ropes of different diameters;

[0030] (5) The present invention can keep the wire rope under a certain tension at all times, and avoid the wire rope from becoming tangled due to slack. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0042] Example 1

[0043] like Figures 1-9 As shown, a winch device for a container transport machine includes: a drum module 1 for winding a wire rope 12, which is installed on the rear frame of the container transport machine and arranged in series along the longitudinal direction of the rear frame of the container transport machine within the cavity of the winch frame 4; a rope guide module 2 for guiding the wire rope 12 to be neatly arranged during the winding process of the drum module; and a tensioning module for providing tension to the wire rope 12 during the winding process of the drum module.

[0044] The drum module 1 is mounted on the winch frame 4 at both ends, including a drum body 102 for winding the wire rope 12 and a motor reducer assembly 101 for driving the drum body 102 to rotate. The motor reducer assembly 101 is mounted on the winch frame 4 via a motor reducer mounting point 402, and its output end is connected to one end of the drum body 102. The other end of the drum body 102 is mounted on the winch frame 4 via a drum mounting shaft assembly 103 at the drum mounting shaft assembly mounting point 401. The drum body 102 rotates under the driving force of the motor reducer assembly 101, and the wire rope 12 is evenly and tightly arranged on the drum body 102. The motor reducer assembly 101 is mounted on the left side of the winch frame 4 and is installed with the drum body 102 through a shaft hole. The drum mounting shaft assembly 103 is mounted on the right side of the winch frame 4 and is installed with the drum body 102 through a shaft hole, and includes a shaft, bearings, sealing rings, lock nuts, etc.

[0045] Rope arranger module 2 includes: a rope arranger frame 205 hinged to the winch frame 4 via a hinge shaft assembly 3; guide pulleys 203 and 206 installed within the rope arranger frame 205 for guiding the wire rope 12; a swing cylinder 10 for driving the rope arranger frame 205 to reciprocate around the axis of the hinge shaft assembly 3; one end of the swing cylinder 10 is hinged to a swing cylinder hinge assembly 7 on the winch frame 4, and the other end is hinged to a swing cylinder hinge assembly 11 on the rope arranger frame 205; and The rope guide frame 205 is hinged to a control rod 201 for monitoring the arrangement direction of the wire rope 12. The control rod 201 has an elongated hole for the wire rope 12 to pass through. A proximity switch is installed on the rope guide frame 205 to monitor the movement state of the control rod 201. The proximity switch is used to detect whether the control rod enters a preset operating distance range. The rope guide frame 205 has an elongated hole for installing the proximity switch. A control valve is used to control the extension or retraction of the swing cylinder 10 according to the detection result of the proximity switch.

[0046] The hinge shaft assembly 3 is fitted with the hinge shaft assembly mounting point 403 on the winch frame 4. Under the driving force of the swing cylinder 10, it swings around the hinge shaft assembly 3. The control rod 201 is fitted onto the control rod hinge assembly 202 via a shaft hole. The wire rope 12 passes through the elongated hole on the control rod 201, allowing the control rod 201 to rotate around the control rod hinge assembly 202 under the action of the wire rope 12. The control rod hinge assembly 202 is fitted onto the circular hole of the rope guide frame 205 via a shaft hole and is fixed to the rope guide frame 205 with fasteners. The control rod hinge assembly 202 and the rope guide frame 205 will not rotate relative to each other. The guide pulley 203 is mounted on the guide pulley shaft assembly 204 and guides the wire rope 12. The guide pulley shaft assembly 204 is mounted on the rope guide frame 205 at both ends through shaft holes and is fixed to the rope guide frame 205 with fasteners. The guide pulley shaft assembly 204 and the rope guide frame 205 will not rotate relative to each other. It includes a pin, bushing, bearing, retaining ring, and fasteners. The second guide pulley 206 is mounted on the pin force sensor assembly 207 and guides the wire rope 12. The pin force sensor assembly 207 is mounted on the rope guide frame 205 at both ends through shaft holes and is fixed to the rope guide frame 205 with fasteners. The pin force sensor assembly 207 and the rope guide frame 205 will not rotate relative to each other. It includes a pin force sensor, bushing, bearing, retaining ring, and fasteners. The pin force sensor measures the tension of the wire rope 12 in real time. The tension of the wire rope is maintained within a safe range through adjustment by the winch's automatic synchronous hydraulic system, ensuring the safety of the entire machine operation.

[0047] The hinge shaft assembly 3 connects the rope guide module 2 to the winch frame 4 and is fixed to the winch frame 4 by fasteners. The hinge shaft assembly 3 and the winch frame 4 will not rotate relative to each other. The rope guide module 2 swings left and right around the hinge shaft assembly 3. It consists of a pin, bearings and mounting fasteners.

[0048] The rear frame of the container truck is the load-bearing component of the entire winch device. In this invention, the winch device is installed at the rear of the rear frame of the container truck, and timber is loaded on the upper surface of the rear frame of the container truck.

[0049] The wire rope 12, wound on the drum body 102, passes through guide pulley 1 203 and guide pulley 206 in sequence, and is led out from the tangential direction of guide pulley 206. The tangential direction of guide pulley 206 coincides with the axis of hinge shaft assembly 3. This ensures that no matter where the rope guide module swings, the position and direction of the wire rope exiting the rope guide module are constant, thus avoiding the phenomena of rope tangling, rope slippage, or rope climbing.

[0050] In this invention, the rope guide module 2 is also hinged to the winch frame 4 via a second hinge shaft assembly 6. The rope guide module 2 swings left and right around the second hinge shaft assembly 6 and consists of a bearing, a sealing ring, and a locking nut. The second hinge shaft assembly 6 coincides with the axis of the first hinge shaft assembly 3, achieving multi-point support for the rope guide frame, reducing swaying during swinging, thereby improving the stability of the rope guide module during swinging and preventing rope tangling, rope slippage, or rope climbing. In this invention, the second hinge shaft assembly 6 is located in the rope-out direction of the second guide pulley 206 and cooperates with the second hinge shaft assembly mounting point 405 on the winch frame 4. Therefore, the second hinge shaft assembly 6 adopts a hollow shaft. After the wire rope 12 is led out from the tangential direction of the second guide pulley 206, it passes through the hollow shaft. While realizing multi-point support and stable swing of the rope guide frame, it perfectly adapts to the internal space of the winch frame, and at the same time ensures the stability of the rope-out position and direction. It can avoid unnecessary wear caused by axial deviation between the wire rope and the second hinge shaft assembly, and can also avoid the phenomena of rope tangling, rope slippage or rope climbing.

[0051] One end of the swing cylinder 10 is connected to the swing cylinder hinge assembly 7, which is connected to the fixed end mounting point 404 of the swing cylinder, thus achieving the hinge connection between the swing cylinder 10 and the winch frame 4. This assembly consists of a pin and fasteners. The other end of the swing cylinder 10 is hinged to the rope guide frame 205 via the swing cylinder hinge assembly 11, which also consists of a pin and fasteners, enabling the rope guide module 2 to swing left and right.

[0052] In this invention, the proximity switch includes a first proximity switch 8 and a second proximity switch 9. The first proximity switch 8 is installed in the elongated hole on the left side of the rope winding frame 205. When the wire rope 12 is wound around the drum body 102 from left to right, it detects the signal from the control rod 201. The installation position of the first proximity switch 8 can be adjusted by setting the elongated hole, thereby adjusting the distance between the first proximity switch 8 and the control rod 201, and achieving a uniform and tight arrangement of wire ropes of different diameters.

[0053] The second proximity switch 9 is installed in the elongated hole on the right side of the rope winding frame 205. When the wire rope 12 is wound around the drum body 102 from right to left, it detects the signal from the control rod 201. The installation position of the second proximity switch 9 can be adjusted by setting the elongated hole, thereby adjusting the distance between the second proximity switch 9 and the control rod 201, and achieving a uniform and tight arrangement of wire ropes of different diameters.

[0054] The tensioning module includes: a roller 14 mounted on the winch frame 4; a cycloidal motor 13 for driving the roller 14 to rotate in the direction of the wire rope 12; a pressing wheel 16 for pressing the wire rope 12 onto the roller 14; a tensioning frame 504 for mounting the pressing wheel 16; and an adjusting bolt 503 for adjusting the distance between the pressing wheel 16 and the roller 14. The adjusting bolt 503 passes through the pressure sleeve 502, the spring 501, and the tensioning frame 504 in sequence before being connected to the winch frame 4.

[0055] The winch frame 4 is provided with a tensioning mechanism mounting point 406 and a roller shaft assembly mounting point 407. The roller 14 is mounted on the roller shaft assembly 15 and rotates under the drive of the cycloidal motor 13. The roller shaft assembly 15 is mounted on the winch frame 4 via the roller shaft assembly mounting point 407 and includes a shaft, bearing, bushing, retaining ring, and sealing ring. The rope pressing wheel 16 is mounted on the rope pressing wheel shaft assembly 17. Both ends of the rope pressing wheel shaft assembly 17 are mounted on the tensioning frame 504 through shaft holes and fixed to the tensioning frame 504 by fasteners. The rope pressing wheel shaft assembly 17 and the tensioning frame 504 will not rotate relative to each other. It includes a pin, bearing, retaining ring, and fasteners. Under the spring force of the spring 501, the rope pressing wheel 16 always presses the wire rope 12, thus providing a certain tension to the wire rope 12. Spring 501 passes through adjusting bolt 503 and is clamped between pressure sleeve 502 and tensioning frame 504, providing tension force for tensioning mechanism 5. Pressure sleeve 502 is located between adjusting bolt 503 and spring 501, providing a support surface for spring 501 and adjusting bolt 503. One end of adjusting bolt 503 is fixed to winch frame 4 by threaded connection, and the other end is connected to tensioning frame 504 through spring 501 and pressure sleeve 502. By adjusting adjusting bolt 503, the installation position of rope pressing wheel 16 is changed, thereby changing the distance between rope pressing wheel 16 and roller 14.

[0056] When the wire rope 12 exits, it passes sequentially through the drum body 102, the elongated hole of the control rod 201, the first guide pulley 203, the second guide pulley 206, the hollow shaft of the second hinge shaft assembly 6, and the gap formed by the roller 14 and the pressure wheel 16. When the rope is wound up, the direction is reversed. The wire rope 12 automatically exits or retracts under the rotation of the drum module 1. The first guide pulley 203 and the second guide pulley 206 guide the wire rope 12. The roller 14 and the pressure wheel 16 clamp the wire rope 12. At the same time, the roller 14 rotates in the exit direction of the wire rope 12, thereby providing a certain tension to the wire rope 12.

[0057] The cycloidal motor 13 is mounted on the winch frame 4 by fasteners. The output shaft of the cycloidal motor 13 is connected to the roller shaft assembly 15, which can drive the roller shaft assembly 15 to rotate, thereby causing the roller 14 to rotate in the direction of the wire rope 12.

[0058] The working principle of the winch device for the container transport machine described in this invention is as follows:

[0059] The pin force sensor assembly 207 can measure the actual tension of the wire rope 12 during operation in real time. The purpose is to keep the tension of the wire rope 12 within the allowable safe range. When the measured tension of the wire rope 12 exceeds the allowable range, the tension of the wire rope 12 can be adjusted through the winch automatic synchronous hydraulic system to keep the tension of the wire rope 12 within the set safe range and ensure the safety of the whole machine operation.

[0060] The winch's automatic synchronous hydraulic system adjusts the wire rope tension in two ways: during rope winding and during rope unwinding. During winding, if the measured wire rope tension exceeds the maximum allowable value, a corresponding signal is transmitted to the drum solenoid valve. The solenoid valve controls the drum motor's displacement, thus reducing the drum's rotational speed and slowing the wire rope winding, thereby reducing the tension. If the measured tension is below the minimum allowable value, the drum's rotational speed is increased. During unwinding, if the measured wire rope tension exceeds the maximum allowable value, a corresponding signal is transmitted to the drum solenoid valve, increasing the drum motor's displacement and increasing the drum's rotational speed, thus speeding up the wire rope unwinding and reducing the tension. If the measured tension is below the minimum allowable value, the drum's rotational speed is decreased.

[0061] Under the premise that the tension of the wire rope 12 is maintained within a constant range, when the wire rope 12 is wound, as the wire rope 12 winds from the left side to the right side of the drum body 102, the swing cylinder 10 shortens to its limit position, and the rope guide module 2 is located on the left side of the drum body 102. Under the action of the tensioning mechanism 5, the wire rope 12 is pressed between the roller 14 and the rope pressing wheel 16. The roller 14 rotates in the direction of rope output under the drive of the cycloidal motor 13, and drives the rope pressing wheel 16 to rotate, providing a certain tension force for the wire rope 12. After being guided by the guide pulley 1 203 and the guide pulley 206, it is wound on the drum body 102.

[0062] When the wire rope 12 completes its first turn and begins the next turn, it automatically moves to the right along the rope groove guide. At this time, the rope guide module 2 remains in its original position, and the angle between the wire rope 12 and the rope guide module 2 increases. Because the wire rope 12 passes through the elongated hole on the control rod 201, the control rod 201 rotates around the control rod hinge assembly 202 under the lateral force of the wire rope 12. The distance between the control rod 201 and the first proximity switch 8 decreases. When the first proximity switch 8 detects the control rod 201, it transmits an electrical signal to the solenoid valve (control valve). The control cylinder 10 extends, and the rope guide module 2 swings around the hinge shaft assembly 3 and the hinge shaft assembly 6. At this time, the angle between the wire rope 12 and the rope guide module 2 decreases, and the distance between the control rod 201 and the first proximity switch 8 increases. When the first proximity switch 8 can no longer detect the control rod 201, the electrical signal disappears, the solenoid valve is de-energized, and the swing cylinder 10 stops extending. When the wire rope 12 completes the current winding and begins the next winding, the above actions are repeated until the wire rope 12 moves to the rightmost side of the drum body 102. At this time, the swing cylinder 10 extends to its limit position.

[0063] When the wire rope 12 moves to the rightmost side of the drum body 102, it automatically falls into the rope loop gap and begins the next layer of winding to the left. At this time, the control rod 201 on the rope guide module 2 is still in its original position. Since the wire rope 12 passes through the elongated hole on the control rod 201, the control rod 201 rotates around the control rod hinge assembly 202 under the action of the lateral force of the wire rope 12. The distance between the control rod 201 and the second proximity switch 9 decreases. When the second proximity switch 9 detects the control rod 201, it transmits an electrical signal to the solenoid valve. The solenoid valve controls the swing cylinder 10 to shorten. At this time, the angle between the wire rope 12 and the control rod 201 decreases, and the distance between the control rod 201 and the second proximity switch 9 increases until the second proximity switch 9 can no longer detect the control rod 201. Then the electrical signal disappears, the solenoid valve is de-energized, and the swing cylinder 10 stops moving. When the wire rope 12 completes the current winding and begins the next winding, the above actions are repeated until the wire rope 12 moves to the leftmost side of the drum body 102. At this time, the swing cylinder 10 shortens to its limit position.

[0064] Repeat the above actions until the specified length of wire rope 12 is evenly and tightly wound on the drum body 102. The above is the working principle when the wire rope 12 is being wound up. When the wire rope 12 is being unwound, the direction of movement of the wire rope is opposite, but the working principle is the same. However, whether the rope is being wound up or unwound, the rotation direction of the cycloidal motor 13 remains unchanged. That is, the cycloidal motor 13 always drives the roller 14 to rotate in the direction of unwound rope, providing tension to the wire rope.

[0065] When the wire rope 12 is wound, it is wound around the drum body 102 one turn at a time, and the diameter of the winding of the wire rope 12 becomes larger and larger. The winding position of the wire rope 12 on the drum body 102 is from top to bottom. Conversely, when the wire rope 12 is unwinding, the unwinding position of the wire rope 12 on the drum body 102 is from bottom to top. The control rod 201 is provided with elongated holes arranged vertically to accommodate the movement trajectory of the wire rope 12.

[0066] The first proximity switch 8 and the second proximity switch 9 are installed on the elongated holes of the rope arranger frame 205. The elongated holes on the rope arranger frame 205 are arranged left and right. By adjusting the installation positions of the first proximity switch 8 and the second proximity switch 9, the distance between the first proximity switch 8 and the second proximity switch 9 and the control rod 201 is changed, thereby changing the swing response time of the swing cylinder 10 to adapt to wire ropes 12 of different diameters. This ensures that when the diameter of the wire rope 12 changes, the wire rope is evenly and tightly arranged on the drum body 102 by adjusting the installation positions of the first proximity switch 8 and the second proximity switch 9.

[0067] The tensioning mechanism 5 can press the pressure wheel 16 onto the wire rope 12, so that the wire rope 12 always maintains a certain tension, avoiding the wire rope 12 from becoming tangled due to loosening. Moreover, the distance between the pressure wheel 16 and the roller 14 can be finely adjusted by rotating the adjusting bolt 503 to accommodate wire ropes 12 of different diameters.

[0068] The winch device for the container transport machine described in this invention is located at the rear of the container transport machine's rear frame. The drum module, rope arranger module, and tensioning module are generally arranged in a streamlined series. The swing cylinder is installed on one side of the rope arranger module. The width occupied by the drum module is consistent with the total width occupied by the rope arranger module and the swing cylinder. This fully utilizes the space along the length of the container transport machine's rear frame, resulting in a compact layout in both width and height without increasing the overall size of the machine or the space occupied by the equipment. It should be noted that when the winch frame is not required, the winch frame in this invention is itself part of the container transport machine's rear frame, bearing the basic functions of the rear frame. When the winch device needs to be installed, the winch frame itself is still part of the container transport machine's rear frame, and while bearing the basic functions of the rear frame, it also serves as the mounting frame for the drum module, rope arranger module, tensioning module, etc. The wire rope on the drum body passes sequentially through the gap formed by the hollow shaft of the drum body, control rod, guide pulley one, guide pulley two, hinge shaft assembly two, rollers, and rope pressing wheel, and finally extends out of the rear frame of the transport machine. During the winding or unwinding process, the wire rope on the drum body undergoes lateral displacement. Under the action of the lateral force of the wire rope, the control rod rotates around the control rod hinge assembly. After the proximity switches on both sides of the control rod detect the control rod, they transmit electrical signals to the solenoid valve, controlling the swing cylinder to extend or shorten. The rope guide module swings around hinge shaft assembly one and hinge shaft assembly two. As the angle between the wire rope and the control rod decreases, the distance between the control rod and the proximity switch increases until the proximity switch can no longer detect the control rod, the electrical signal transmitted to the solenoid valve disappears, and the swing cylinder stops swinging. When the wire rope winds or unwinds to the next turn, repeat the above actions until the wire rope reaches one edge of the drum body. At this time, the rope guide swings in the opposite direction under the action of the swing cylinder. When the wire rope reaches the other side of the drum body, the rope guide swings in the opposite direction again under the action of the swing cylinder. The rope guide swings back and forth until the specified length of wire rope is wound on the drum body or unwinds to the required length.
