Description

Technical Field

[0001] This invention relates to the field of winch technology, and in particular to a winch device. Background Technology

[0002] The bidirectional spiral screw rope winding device is a commonly used mechanism in winches to achieve orderly winding of wire rope. This device transmits the rotational motion of the drum to the bidirectional spiral screw synchronously via chain drive, driving the shuttle seat to reciprocate along the axis of the drum, so that the wire rope is neatly arranged layer by layer, turn by turn.

[0003] However, the aforementioned automatic rope-laying device is essentially an open-loop mechanical synchronization system. Its transmission ratio is designed based on the nominal diameter of the wire rope, which cannot adapt to the cumulative errors caused by actual rope diameter tolerances and changes in coil diameter. As the number of rotations increases, a phase drift occurs between the theoretical position of the shuttle seat and the actual landing point of the wire rope. When the deviation exceeds a threshold, rope tangling and rope climbing phenomena occur. In existing technology, the bidirectional helical screw and the drum are rigidly fixedly connected. Once assembled, the rope-laying phase cannot be adjusted. After accumulated errors occur, the machine must be stopped, disassembled, and readjusted. It lacks a convenient phase fine-tuning function, which seriously affects the quality of rope laying and the continuity of operation. Summary of the Invention

[0004] The purpose of this invention is to provide a winch device that solves the problems existing in the prior art, has a simple structure, is easy to operate, and can improve the quality of rope laying.

[0005] To achieve the above objectives, the present invention provides the following solution: This invention provides a winch device, including a frame, a drum assembly, a rope arrangement device, and a transmission device. The drum assembly, rope arrangement device, and transmission device are all mounted on the frame. The drum assembly is rotatable about its own axis. The rope arrangement device guides the rope to move axially along the drum assembly, causing the rope to be arranged tightly and wound layer by layer along the axial direction on the surface of the drum assembly as it rotates. The transmission device has a connected state and a disconnected state. When the transmission device is connected, the rotation of the drum assembly is transmitted to the rope arrangement device. When the transmission device is disconnected, the drum assembly is disconnected from the rope arrangement device, and the position of the rope led out by the rope arrangement device can be adjusted axially along the drum assembly.

[0006] In some embodiments, the rope-laying device includes a wire cutter and a lead screw, the axis of which is parallel to the axis of the drum device. The wire cutter is movably connected to the frame along the axis of the drum device and threaded to the lead screw. The transmission device includes a transmission mechanism and an adjustment mechanism. The input component of the transmission mechanism is fixedly connected to the drum device, and the adjustment mechanism is circumferentially fixedly connected to the lead screw. The adjustment mechanism is movable along the axis of the lead screw to connect or disconnect with the output component of the transmission mechanism, so that the transmission device switches between the connected state and the disconnected state. When the transmission device is in the disconnected state, the axial position of the wire cutter relative to the drum device can be adjusted to adjust the position of the rope led out by the rope-laying device.

[0007] In some embodiments, the adjusting mechanism includes a transmission flange, a first connecting member, an adjusting seat, and an elastic member. The adjusting seat is circumferentially fixedly connected to one end of the lead screw. The first connecting member is fixedly disposed on the output component of the transmission mechanism, and the adjusting seat is movable along the axial direction of the lead screw. The axial direction of the lead screw is parallel to the axial direction of the winding device. A limiting member is fixedly disposed on the lead screw. The elastic member is disposed between the limiting member and the adjusting seat. Under the elastic force of the elastic member, the adjusting seat remains connected to the first connecting member to keep the transmission device in the connected state. Axially pulling the adjusting seat separates the adjusting seat from the first connecting member to keep the transmission device in the disconnected state. When the transmission device is in the disconnected state, rotating the adjusting seat can drive the lead screw to rotate, thereby adjusting the axial position of the wiring device relative to the winding device.

[0008] In some embodiments, the lead screw is provided with a first helical groove and a second helical groove with opposite directions of rotation, and the wiring device is provided with a boss that can be embedded in the helical grooves of the first and second helical grooves. The two ends of the lead screw are provided with transition grooves that are respectively connected to the first and second helical grooves. The transition grooves are used to switch the boss from the helical groove of the first helical groove to the helical groove of the second helical groove, or from the helical groove of the second helical groove to the helical groove of the first helical groove, when the boss reaches the end of its stroke.

[0009] In some embodiments, the rope-laying device further includes a guide rod, the axis of which is parallel to the axis of the lead screw, the guide rod is fixedly connected to the frame, and the rope-laying device is slidably connected to the guide rod along an axis parallel to the drum device.

[0010] In some embodiments, the cable maker includes a base and a guide assembly and a pressing wheel disposed on the base. The guide assembly includes two guide wheels with their rotation axes perpendicular to the axial direction of the winding device. The rotation axis of the pressing wheel is parallel to the axial direction of the winding device. The guide rod is located on the side of the lead screw away from the winding device. The rotation axes of the two guide wheels are spaced apart in an axis parallel to the axial direction of the winding device. The rope passes sequentially through the space between the two guide wheels and the space between the pressing wheel and the base before being wound onto the winding device.

[0011] In some embodiments, the rotation axes of the two guide wheels are also spaced apart in a direction perpendicular to the axial direction of the drum assembly.

[0012] In some embodiments, the transmission mechanism includes a first sprocket, a second sprocket, and a chain. The first sprocket is rotatably mounted on the frame and connected to the transmission flange. The second sprocket is fixedly connected to one end of the drum assembly. The first sprocket and the second sprocket are connected by the chain drive. The frame is also provided with a tensioning device that abuts against the chain to adjust the tension of the chain.

[0013] In some embodiments, the frame includes a first frame and a second frame, the first sprocket, the rope feeding device, and the adjusting mechanism are fixedly mounted on the first frame, and the second sprocket and the drum device are fixedly mounted on the second frame, and the first frame is rotatable relative to the second frame.

[0014] In some embodiments, a drive device is also included, the output of which is connected to the drum assembly for driving the drum assembly to rotate.

[0015] The present invention achieves the following technical effects compared to the prior art: The winch device provided by this invention has a transmission device with a connected state and a disconnected state. This allows the rope-laying device to operate synchronously with the drum device during normal rope winding and unwinding operations, ensuring the rope is tightly and evenly arranged on the drum. This avoids rope tangling, overlapping, and entrapment caused by asynchronous rope laying, thereby reducing mutual compression and wear of the ropes, extending the service life of the ropes and the drum device 2, and reducing safety risks such as rope breakage and slippage. When it is necessary to adjust the rope laying position, switching to the disconnected state cuts off the power transmission between the drum device and the rope-laying device, allowing the operator to... The position of the rope-laying device can be independently and freely adjusted axially on the drum device, precisely adjusting the rope index exit point to ensure that the rope exit angle always meets the specifications. This avoids problems such as rope deviation, derailment, and abnormal wear caused by excessive rope exit angle. At the same time, this design can complete the fine adjustment of the rope position without stopping the machine for disassembly or using additional tools, which greatly reduces the labor intensity and operation difficulty of manual intervention, improves the convenience and accuracy of rope adjustment, and effectively solves the technical problems of fixed rope position, poor adaptability, time-consuming and laborious manual adjustment, and easy rope disorder in traditional winch devices.

Detailed Implementation

[0019] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] This invention provides a hoisting device, such as... Figure 1-6As shown, the device includes a frame, a drum assembly 2, a rope arrangement device, and a transmission device. The drum assembly 2, rope arrangement device, and transmission device are all mounted on the frame. The drum assembly 2 can rotate around its own axis. The rope arrangement device guides the rope to move axially along the drum assembly 2 and arranges the rope tightly and layer by layer on the surface of the drum assembly 2 as it rotates. The transmission device has a connected state and a disconnected state. When the transmission device is connected, the rotation of the drum assembly 2 can be transmitted to the rope arrangement device through the transmission device. When the transmission device is disconnected, the drum assembly 2 is disconnected from the rope arrangement device, and the position of the rope led out by the rope arrangement device can be adjusted axially along the drum assembly 2. In this embodiment, the transmission device in the winch has a connected state and a disconnected state, so that the rope arrangement device operates synchronously with the drum assembly 2 during normal rope winding and unwinding operations, ensuring that the rope is tightly and evenly arranged on the drum assembly 2. This design avoids rope tangling, overlapping, and entrapment caused by asynchronous rope laying, thereby reducing mutual compression and wear of the ropes, extending the service life of the ropes and drum device 2, and reducing safety risks such as rope breakage and slippage. When it is necessary to adjust the rope laying position, the power transmission between the drum device and the rope laying device is cut off by switching to the disconnected state. The operator can independently adjust the position of the rope laying device axially on the drum device, accurately adjust the rope index exit point, and ensure that the rope exit angle always meets the specifications. This avoids problems such as rope deviation, derailment, and abnormal wear caused by excessive rope exit angle. At the same time, this design can complete the fine adjustment of the rope laying position without stopping the machine for disassembly or using additional tools, which greatly reduces the labor intensity and operation difficulty of manual intervention, improves the convenience and accuracy of rope laying adjustment, and effectively solves the technical problems of fixed rope laying position, poor adaptability, time-consuming and laborious manual adjustment, and easy rope laying disorder of traditional winch devices.

[0022] In some embodiments of this example, the rope-laying device includes a rope connector 12 and a lead screw 14. The axial direction of the lead screw 14 is parallel to the axial direction of the drum device 2. The rope connector 12 is movably connected to the frame along the axial direction of the drum device 2 and threadedly connected to the lead screw 14. The transmission device includes a transmission mechanism and an adjustment mechanism. The input component of the transmission mechanism is fixedly connected to the drum device 2, and the adjustment mechanism is circumferentially fixedly connected to the lead screw 14. The adjustment mechanism can move along the axial direction of the lead screw 14 to connect or disconnect with the output component of the transmission mechanism, so that the transmission device can switch between a connected state and a disconnected state. When the transmission device is in the disconnected state, the axial position of the rope connector 12 relative to the drum device 2 can be adjusted to adjust the position of the rope led out by the rope-laying device. The rope connector 12 is movably connected to the frame along the axial direction of the drum device 2. It has an internal thread structure (such as a threaded hole or threaded sleeve) that mates with the external thread of the lead screw 14, so that the rope connector 12 is sleeved on the lead screw 14 through the thread pair. When the drum device 2 rotates, its rotational power is transmitted through the input component of the transmission mechanism. The power is transmitted to the output component. In the connected state, the output component drives the adjustment mechanism, which is circumferentially fixed to the lead screw 14, to rotate synchronously. This drives the lead screw 14 to rotate, and the rotational motion of the lead screw 14 is converted into the linear reciprocating motion of the cable 12 along the axis of the drum device 2 through the threaded pair. This ensures that the displacement speed of the cable 12 matches the rotational speed and rope diameter of the drum device 2, thereby ensuring that the rope is evenly and orderly arranged layer by layer on the drum device 2, effectively avoiding rope tangling and overlapping. At the same time, the adjustment mechanism is circumferentially fixed to the lead screw 14 and has the function of moving axially to connect or disconnect the output component of the transmission mechanism. During normal winch operation, the connection state is switched to realize the linkage between the rope arrangement action and the winch winding action. When it is necessary to adjust the position of the rope index exit point, deal with rope jamming, or perform equipment maintenance, the connection state is switched to the disconnect state to quickly and conveniently cut off the power transmission, allowing the cable 12 to be freed from the driving constraint of the lead screw 14. This provides a great degree of operational freedom and safety guarantee for manually fine-tuning the rope position, dealing with rope jamming, or performing equipment maintenance.

[0023] In some embodiments of this example, the adjusting mechanism includes a transmission flange 10, a first connecting member 9, an adjusting seat 8, and an elastic member 6. The adjusting seat 8 is circumferentially fixedly connected to one end of the lead screw 14. The first connecting member 9 is fixedly mounted on the output component of the transmission mechanism, and the adjusting seat 8 can move along the axial direction of the lead screw 14. The axial direction of the lead screw 14 is parallel to the axial direction of the drum device 2. A limiting member 7 is fixedly mounted on the lead screw 14. The elastic member 6 is disposed between the limiting member 7 and the adjusting seat 8. Under the elastic force of the elastic member 6, the adjusting seat 8 and the first connecting member 9 remain connected so that the transmission device is in a connected state. Axially pulling the adjusting seat 8 separates the adjusting seat 8 from the first connecting member 9 so that the transmission device is in a disconnected state. When the transmission device is in a disconnected state, rotating the adjusting seat 8 can drive the lead screw 14 to rotate, thereby adjusting the axial position of the wiring harness 12 relative to the drum device 2. During normal hoisting operation, the elastic member 6... The elastic component 6 is in a pre-compressed state and provides continuous axial elastic force. This elastic force acts between the limiting component 7 and the adjusting seat 8, continuously pushing the adjusting seat 8 along the axial direction of the lead screw 14 towards the first connecting component 9. This makes the end face of the adjusting seat 8 tightly fit with the corresponding mating surface of the first connecting component 9, which is fixed on the output component of the transmission mechanism. A circumferential lock is formed by the friction between the two mating surfaces or the geometric meshing structure such as the teeth / keyways on the end faces, ensuring that the adjusting seat 8 and the first connecting component 9 will not rotate relative to each other or move axially during the transmission of torque. This achieves continuous and reliable transmission of the rotational power of the drum device 2 through the output component of the transmission mechanism → the first connecting component 9 → the adjusting seat 8 → the lead screw 14. Moreover, this elastic compression connection does not require additional bolts, pins or other locking devices, which can effectively prevent accidental disengagement caused by vibration, impact or alternating load during the winch process, ensuring the stability and safety of power transmission.

[0024] When the rope position needs to be adjusted, the adjusting seat 8 can be pulled axially by overcoming the elastic force of the elastic element 6 to quickly and smoothly disconnect the power. After being released, the elastic element 6 automatically drives the adjusting seat 8 to reset and re-engage. There is no need for manual alignment or secondary locking, which greatly simplifies the operation process. At the same time, the overall structure is compact, with fewer parts and easy assembly, which significantly reduces manufacturing costs and maintenance difficulty.

[0025] An outer cover 19 is provided on the outside of the lead screw 14. The outer cover 19 covers the outside of the lead screw 14. The two ends of the outer cover 19 are equipped with sealing structures to prevent external contaminants such as dust, oil, and water stains from entering the threaded pair between the lead screw 14 and the wiring device 12. This prevents impurities from getting stuck, which could cause the lead screw 14 to rotate poorly or the threads to wear. It also prevents internal grease from leaking out to maintain good lubrication. In addition, the outer cover 19 completely seals the rotating lead screw 14, effectively preventing operators from accidentally coming into contact with the rotating parts during equipment operation or maintenance, and avoiding safety accidents such as pinching or entanglement. During normal hoisting operation, the outer cover 19 is fixed. The screw 14 is stationary and rotated internally by a transmission mechanism. When the position of the wiring device 12 needs to be adjusted, the operator can manually remove the outer cover 19 and manually rotate the adjusting seat 8 to rotate the screw 14 to achieve fine adjustment of the axial position of the wiring device 12. If the screw 14 needs to be cleaned, lubricated or replaced, the outer cover 19 can be removed to expose the screw 14 body for easy maintenance. After maintenance, the outer cover 19 can be reinstalled to restore the protective function, thereby effectively extending the service life of the screw 14 and the wiring device 12, and improving the operational stability, operational safety and maintenance convenience of the entire rope laying device.

[0026] In some embodiments of this example, the lead screw 14 is provided with a first spiral groove and a second spiral groove with opposite directions of rotation, and the wiring device 12 is provided with a boss that can be embedded in the spiral grooves of the first and second spiral grooves. The two ends of the lead screw 14 are provided with transition grooves, which are respectively connected to the first and second spiral grooves. The transition grooves are used to switch the boss from the spiral groove of the first spiral groove to the spiral groove of the second spiral groove, or from the spiral groove of the second spiral groove to the spiral groove of the first spiral groove, when the boss reaches the end of its stroke. The lead screw 14 is provided with a first spiral groove and a second spiral groove with opposite directions of rotation. When the wiring device 12 rotates with the lead screw 14, it can automatically and smoothly switch directions when it reaches the end of its stroke by relying on the two opposite first and second spiral grooves without relying on any external reversing mechanism. This purely mechanical design not only achieves rigid synchronization between the rope-laying action and the winding action of the drum device 2, ensuring that the rope is evenly and tightly arranged layer by layer on the drum device 2 and completely eliminating rope tangling, but also greatly simplifies the overall transmission structure, reduces equipment failure rate and maintenance costs, and improves the stability and reliability of the winch device in continuous operation. When the cable handler 12 reaches the end of its stroke, the geometric contour of the transition groove can guide the boss to smoothly slide from one spiral groove into another spiral groove with the opposite direction of rotation, avoiding hard jamming or violent collision, ensuring the continuity and smoothness of the rope-laying reversing action, effectively preventing mechanical wear and uneven rope arrangement caused by reversing impact, eliminating the need for a complex external reversing control mechanism, and enabling the entire rope-laying system to achieve reliable automatic reciprocating motion entirely through a purely mechanical structure, greatly improving the service life and reliability of the equipment.

[0027] In some embodiments of this example, the rope-laying device further includes a guide rod, the axis of which is parallel to the axis of the lead screw 14. The guide rod is fixedly connected to the frame, and the cable slidably connected to the guide rod along an axis parallel to the drum device 2. The parallel guide rods provide stable support and precise linear guidance for the reciprocating motion of the cable 12. This design effectively withstands the lateral force and gravity experienced by the cable 12 during rope laying, preventing the cable 12 from tilting or swaying due to uneven force, thereby ensuring the stability of the rope entry angle and the neatness of the arrangement. At the same time, the guide rod shares the radial load of the lead screw 14, preventing the lead screw 14 from deforming due to bending stress, significantly reducing the frictional resistance between the lead screw 14 and the cable 12, making the rope laying action smoother and more stable, and greatly extending the service life of the lead screw 14 and the entire rope-laying device.

[0028] In some embodiments of this example, the wiring device includes a base 13 and a guide assembly and a rope pressing wheel 15 disposed on the base 13. The guide assembly includes two guide wheels 16, the rotation axis of which is perpendicular to the axial direction of the drum device 2, and the rotation axis of the rope pressing wheel 15 is parallel to the axial direction of the drum device 2. The guide rod is located on the side of the lead screw 14 away from the drum device 2. The rotation axes of the two guide wheels 16 are spaced apart in an axis parallel to the axial direction of the drum device 2. The rope passes sequentially through the space between the two guide wheels 16 and the space between the rope pressing wheel 15 and the base. The space between 13 is then wound onto the drum device 2. By setting guide wheels 16 and pressure wheels 15 on the base 13, the guide wheels 16 can effectively change the direction of the rope, accurately and smoothly introducing the rope into the rope layer of the drum device 2, avoiding direct friction and scraping between the rope and the frame; the pressure wheels 15 can apply downward pressure to the rope before it is wound into the drum device 2, ensuring that the rope is tightly and flatly attached to the surface of the drum device 2 or the previous layer of rope, effectively preventing arching, skipping, or overlapping of the rope during the arrangement process. The two work together to further improve the neatness and safety of multi-layer winding, and significantly reduce rope wear and fatigue damage.

[0029] In some embodiments of this example, the two guide wheels 16 have gaps in both the horizontal and axial directions to form a guide channel for the rope to pass through. In the horizontal direction, the gap width between the two guide wheels 16 is slightly larger than the rope diameter, allowing the two guide wheels 16 to clamp and constrain the left and right sides of the rope, effectively limiting the lateral swing and deviation of the rope in the horizontal direction, ensuring that the rope always runs stably along the predetermined path, and preventing the rope from coming out of the guide channel due to vibration of the winch device or changes in the rope exit angle. In the axial direction, the gap height between the two guide wheels 16 is also slightly larger than the rope diameter, allowing the rope to move freely axially between the two guide wheels 16, which can adapt to different winding layer diameters. The axial displacement of the rope caused by the change provides sufficient space for thicker ropes to pass through, preventing them from getting stuck due to insufficient clearance or from being worn down due to excessive tension. By splitting the guide assembly into two guide wheels 16 and reserving the aforementioned bilateral clearance, the rope can be provided with appropriate lateral and axial buffer space, effectively absorbing and adapting to rope vibration, skewness, and tension fluctuations caused by different winding layer diameters under complex working conditions. This prevents the rope from getting stuck or from being worn down due to excessive tension. At the same time, this gap-type guide structure can adapt to various rope specifications without the need for a complex adjustment mechanism, greatly improving the versatility and adaptability of the device.

[0030] In some embodiments of this example, the transmission mechanism includes a first sprocket 11, a second sprocket 4, and a chain 3. The first sprocket 11 is rotatably mounted on the frame and connected to the transmission flange 10. The second sprocket 4 is fixedly connected to one end of the drum device 2. The first sprocket 11 and the second sprocket 4 are connected by the chain 3. A tensioning device 5 is also provided on the frame, which abuts against the chain 3 to adjust the tension of the chain 3. The chain transmission mechanism transmits the power of the drum device 2 to the rope laying device, which has the advantages of smooth transmission, strong load-bearing capacity, and adaptability to transmission with a large center distance, ensuring the synchronization of the winch and rope laying actions. At the same time, by adding a tensioning device 5 abutting against the chain 3 on the frame, the appropriate tension of the chain 3 can be adjusted and maintained in real time, effectively avoiding tooth skipping, chain derailment, or transmission lag caused by the looseness of the chain 3, ensuring the accuracy and reliability of power transmission, and also helping to reduce abnormal wear of the chain 3 and sprocket, significantly improving the service life and operational stability of the entire transmission system.

[0031] In some embodiments of this example, the frame includes a first frame 17 and a second frame 18. A first sprocket 11, a rope feeding device, and an adjusting mechanism are fixedly mounted on the first frame 17, while a second sprocket 4 and a drum device 2 are fixedly mounted on the second frame 18. The first frame 17 is rotatable relative to the second frame 18. By designing the frame as a first frame 17 and a second frame 18 that can rotate relative to each other, the rope introduction angle can be adjusted. At the same time, this foldable / rotatable frame design also provides great space convenience for the installation, debugging, and daily maintenance of the equipment, significantly improving the overall adaptability and ease of operation of the winch device.

[0032] In some embodiments of this example, a drive device 1 is also included. The output end of the drive device 1 is connected to the drum device 2 and is used to drive the drum device 2 to rotate. This structural design allows the power output of the drive device to be directly applied to the drum device 2, enabling the drum device 2 to rotate smoothly and efficiently under the drive of the drive device. This, in turn, drives the rope wound on the drum device 2 to perform winding and unwinding operations, completing the lifting or traction of heavy objects. At the same time, the connection between the drive device and the drum device 2 simplifies the power transmission path, reduces energy loss and failure points in intermediate transmission links, and improves the overall transmission efficiency and operational reliability of the winch device. Furthermore, the drive device 1 can be selected from different power forms such as electric, hydraulic, or pneumatic according to actual working conditions, flexibly adapting to the winch requirements of different tonnages and different working environments. This provides a stable and controllable power source for the entire winch device, ensuring the continuity and safety of winch operations.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
