Description

Technical Field

[0001] This application relates to the field of surface operation technology, and more particularly to a winch and surface cleaning system. Background Technology

[0002] Winches, as a common hoisting device, are widely used in many fields such as shipbuilding, engineering machinery, exploration, and rescue, for the winding, pulling, and storage of cables, wires, or hoses.

[0003] In surface operations such as wind turbine tower cleaning, ship sidewall maintenance, and large storage tank inspection, the work equipment (such as cleaning machines and wall-climbing robots) typically requires a continuous supply of water or electricity. Therefore, winches used for deploying and managing water pipes, cables (power / signal cables), or ropes become critical equipment.

[0004] Existing winches generally only allow for the deployment and retrieval of a single cable, failing to meet the synchronous deployment and retrieval requirements of multiple cables in complex operating systems. Therefore, existing winch technologies are unsuitable for complex operational scenarios such as wind turbine tower cleaning. Consequently, providing a solution for the synchronous deployment and retrieval of multiple cables in complex operating systems is a pressing technical problem that needs to be addressed. Utility Model Content

[0005] This application provides a winch and surface cleaning system to solve one or more of the technical problems mentioned above in the prior art.

[0006] According to one aspect of this application, a winch is disclosed, including a base;

[0007] A drive component is mounted on the base;

[0008] A roller is rotatably supported on the base and is connected to the output shaft of the drive component. The roller has cable passage holes on its wall.

[0009] The first cable guide component and the second cable guide component are respectively disposed at both ends of the roller, and each cable guide component has a cable inlet and a cable outlet. The first cable guide component and the second cable guide component extend from the first end end and the second end end of the roller to the shaft hole of the roller, and each cable outlet is connected to the cable through hole.

[0010] In some embodiments of this application, the winch includes a cable support pulley, which is disposed on one side of the drum and is movable along the axial direction of the drum.

[0011] In some embodiments of this application, the projection of the cable support pulley on the horizontal plane does not at least partially coincide with the projection of the roller on the horizontal plane.

[0012] In some embodiments of this application, the number of cable support pulleys is two, and the two cable support pulleys are arranged in parallel along a direction perpendicular to the axis of the drum.

[0013] In some embodiments of this application, the winch includes a linear displacement assembly and a guide assembly, both of which are disposed on the base. The linear displacement assembly includes a lead screw and a nut, and the guide assembly includes a guide rail and a slider. The lead screw is parallel to and spaced apart from the guide rail, and the slider is connected to the nut. The at least two cable support pulleys are fixed to the side of the slider away from the nut, and the lead screw is connected to the output end of the drive component.

[0014] In some embodiments of this application, the lead screw is a crescent-pin reciprocating lead screw; and / or,

[0015] The guide assembly includes two spaced and parallel support plates, the support plates being located on the side of the slider away from the nut, the end of the support plate closer to the slider being connected to the slider, and the two ends of the axle of each cable support pulley being respectively disposed on the two support plates.

[0016] In some embodiments of this application, the linear displacement assembly includes a belt drive mechanism, wherein the driving pulley and the driven pulley of the belt drive mechanism are respectively connected to the output shaft of the drive component and the lead screw.

[0017] In some embodiments of this application, the roller is provided with a first rotating shaft and a second rotating shaft at both ends. The first rotating shaft and the second rotating shaft are fixedly connected to the roller. The first rotating shaft is connected to the output shaft of the drive component. The first rotating shaft and the second rotating shaft are respectively sleeved on the outside of the first cable guide component and the second cable guide component, and the first rotating shaft and the second rotating shaft are rotatable relative to the first cable guide component and the second cable guide component, respectively.

[0018] In some embodiments of this application, the axis of the cable inlet is perpendicular to the axis of the cable outlet.

[0019] According to another aspect of this application, a surface cleaning system is also disclosed, the surface cleaning system comprising a working device, water pipes, cables and a winch as described in any of the above embodiments, wherein the water pipes and cables are wound on the drum and one end of the water pipes and cables is connected to the working device.

[0020] The winch in the above embodiments of this application adopts a unique double-end guide structure design, which allows the winch to simultaneously introduce different media pipelines from both ends of the drum (e.g., a water pipe from one end and a power cable from the other end). This provides great wiring flexibility for complex operating systems that require multiple media supplies, meets the needs of different application scenarios, and enables the synchronous winding and unwinding of multiple pipelines in complex operating scenarios such as wind turbine tower cleaning.

[0021] Furthermore, the cable outlets of the first and second cable guide components of the winch in this application are connected to the cable through holes on the drum wall. This structure provides a smooth passage path for the cable, effectively avoiding severe friction and compression between the cable and the drum end flange during the winding and unwinding process. It significantly reduces the bending stress and surface wear of the cable, thereby greatly extending the service life of the cable and reducing maintenance and replacement costs.

[0022] In addition to the above, the cable guide component of the winch of this application extends into the shaft hole of the drum, so that the critical guide and transition parts are accommodated in the internal space of the drum. This structure not only optimizes the overall structural layout of the winch, making it more compact, but also provides physical protection for the cable in the most wear-prone transition area, avoiding accidental interference and collision with the outside world, reducing system failure downtime caused by pipeline rupture, leakage or short circuit, and improving the operational reliability and safety of the system.

The objectives and other advantages of this application can be realized and obtained by means of the structures specifically pointed out in the specification and drawings.

[0047] The winch provided in this application embodiment can be applied to the fields of ship hulls, oil tanks, water tanks, bridges, high towers, wind turbines, etc., such as surface cleaning devices or systems for operation scenarios such as wind turbine tower cleaning, ship sidewall cleaning, and large storage tank cleaning, for the winding, pulling, and storage of cables, wires, or hoses.

[0048] Figure 1 This is a schematic diagram of the structure of a winch according to an embodiment of this application. Figure 2 for Figure 1 The diagram shows another angle of the cable car's structure, as shown below. Figure 1 and Figure 2 As shown, the winch includes at least a base 100, a drive component 200, a drum 300, a first cable guide component 410, and a second cable guide component 420.

[0049] A drive component 200 is mounted on the base 100; a roller 300 is rotatably supported on the base 100 and is connected to the output shaft of the drive component 200. The roller 300 has a cable passage hole 310 on its cylindrical wall; a first cable guide component 410 and a second cable guide component 420 are respectively mounted on both ends of the roller 300, and each cable guide component has a cable inlet 431 and a cable outlet 432. The first cable guide component 410 and the second cable guide component 420 extend from the first end and the second end of the roller 300 into the shaft hole of the roller 300, respectively, and each cable outlet 432 communicates with the cable passage hole 310.

[0050] The drive component 200, roller 300, first cable guide component 410, and second cable guide component 420 are all supported on the base 100. During operation, the base 100 can be supported on a horizontal surface. The drive component 200 can be exemplarily a drive motor, which can be fixed to the base 100 by screws or bolts. The drive motor is used to drive the roller 300 to rotate, and completes the winding and unwinding of the cable during the rotation of the roller 300. The first cable guide component 410 and the second cable guide component 420 are used to guide the first cable and the second cable, respectively. The first cable and the second cable enter from the cable inlet 431 of the first cable guide component 410 and the cable inlet 431 of the second cable guide component 420, respectively, and extend from the cable outlet 432 of the first cable guide component 410 and the cable outlet 432 of the second cable guide component 420 into the shaft hole of the roller 300. Then, the first cable and the second cable extend from the cable through hole 310 on the roller 300 to the outside of the roller 300 and are wound around the outer wall of the roller 300.

[0051] refer to Figure 1 and Figure 2 Specifically, the roller 300 may include a roller body and baffles disposed at both ends of the roller body. The baffles extend outward from the outer wall of the roller body in a direction perpendicular to the axis of the roller 300. The baffles are used to limit the pipes and cables wound on the outer wall of the roller 300 in the axial direction of the roller 300 so that the pipes and cables are all wound on the roller body.

[0052] Figure 8 This is a schematic diagram of the structure of the base 100 according to an embodiment of this application, as shown below. Figure 8 As shown, the base 100 has rollers at its bottom, which are used to move the base 100 on the support surface to adjust the position of the winch. Specifically, the base 100 may include end supports respectively disposed on the outer sides of both ends of the drum 300 and multiple transverse connecting rods for connecting the two end supports. It can be understood that the base 100 serves to achieve rotational support of the drum 300 and movement of the winch, and its specific structure can be set based on actual needs.

[0053] Specifically, the drive component 200 can be detachably connected to the end bracket of the base 100 via screws or bolts, while the first cable guide component 410 and the second cable guide component 420 can both be mounted on the end bracket of the base 100. The roller 300 can be rotatably supported on the base 100 via bearings and a rotating shaft. (Reference) Figure 4 and Figure 5 The winch may further include a power module 900 for supplying power to the drive unit 200. Similarly, the power module 900 may also be fixed to the end bracket of the base 100.

[0054] In some embodiments of this application, the winch includes a cable support pulley 500, which is disposed on one side of the drum 300 and is movable along the axial direction of the drum 300.

[0055] The axial direction of roller 300 is specifically as follows: Figure 3 In the transverse direction of the winch shown, the cable support pulley 500 supports the first and second cables, allowing the cables to move in a predetermined direction during winding and unwinding. The cable support pulley 500 can also be mounted on the base 100, specifically at the top of the base 100. For example, the projection of the cable support pulley 500 onto the horizontal plane does not at least partially coincide with the projection of the roller 300 onto the horizontal plane (see reference). Figure 5 );like Figure 4 As shown, the cable support pulley 500 can be located on the upper side of the drum body. When the cable is released from the drum 300, it enters the cable support pulley 500 in a smooth and natural tangential direction. When the cable enters the drum 300, it also enters in a smooth and natural tangential direction. This ensures that the cable's entry angle when approaching the drum 300 or its exit angle when leaving the drum 300 are controlled to be very small. This guarantees that the cable can be tightly and neatly wound on the drum 300, avoiding the "tangled" phenomenon of the cable jumping, crossing, or embedding into the lower layer of cable during winding. Furthermore, the cable forms a natural "S"-shaped bend between the cable support pulley 500 and the drum 300. Gravity acting on this bend helps increase the wrap angle between the cable and the pulley / drum 300, thereby increasing the static friction between the cable and the pulley / drum 300 and preventing the cable from slipping on the pulley / drum 300.

[0056] The axially movable cable support pulley 500 can precisely track the winding position of the cable on the drum 300. The moving speed of the cable support pulley 500 can be matched with the rotational speed of the drum 300, so that the cable can be evenly distributed on the drum 300 when it is wound, avoiding inconsistent heights of the cable in the radial direction of the drum 300 on different cross sections. The winch with this structure can automatically complete the precise winding from empty drum to full drum and from one layer to multiple layers without manual intervention in the cable winding process.

[0057] Furthermore, the axially movable cable support pulley 500 can always be kept directly in front of the point closest to the cable winding point, reducing lateral friction and scratching between the cable and the side of the roller 300 or adjacent cables.

[0058] In some embodiments of this application, there are two cable support pulleys 500, which are arranged in parallel along a direction perpendicular to the axis of the roller 300.

[0059] The direction perpendicular to the axis of the roller 300 can be, for example, Figure 4 The lateral direction in the side view of the winch shown is... Figure 4 In the illustrated embodiment, there are two cable support pulleys 500. At this time, the two cable support pulleys 500 move along... Figure 4 The cables are arranged in parallel horizontal directions, and both cable support pulleys 500 are located in... Figure 4 The winch shown is positioned to the upper right of drum 300. In this embodiment, when the winch is used to wind up and unwind the first and second cables, the first and second cables can pass through the gap between the two cable support pulleys 500. The cables are then provided with rolling support by the pulleys on both sides, thereby converting potential sliding friction into rolling friction. This arrangement allows the two cable support pulleys 500 to provide effective support to the cables from both sides, thus preventing cable wear during windup and unwinding.

[0060] It is understood that the method of setting two cable support fixed pulleys 500 as described in the above embodiments is only a preferred method. In some other embodiments, only one cable support fixed pulley 500 may be set.

[0061] In addition, when the first and second conduits are water pipes and cables respectively, the water pipes and cables enter through the cable inlets of the two cable guide components and extend through the cable outlets of the two cable guide components, respectively. They then extend from the cable through-holes 310 on the roller 300 to the outer peripheral wall of the roller 300 and wrap around the roller 300. In actual operation, the cables in the two cable guide components extend simultaneously from the cable through-holes 310 and are bundled together and wrapped around the roller 300. To protect the cables during dragging, in actual operation, the two cables are bundled together with an additional rope fixed to the roller 300. The cables are moved indirectly by pulling the rope, thus avoiding damage caused by direct dragging. The method of fixing the rope to the roller 300 is not limited, as long as it ensures that the rope does not loosen from the roller 300 when dragging.

[0062] In some embodiments, the winch includes a linear displacement assembly 600 and a guide assembly 700, both of which are disposed on the base 100. The linear displacement assembly 600 includes a lead screw 610 and a nut 620, and the guide assembly 700 includes a guide rail 710 and a slider 720. The lead screw 610 is parallel to and spaced apart from the guide rail 710, and the slider 720 is connected to the nut 620. At least two cable support pulleys 500 are fixed to the side of the slider 720 away from the nut 620. The lead screw 610 is connected to the output end of the drive component 200.

[0063] The linear displacement assembly 600 is used to achieve linear displacement of the cable support pulley 500 along the axial direction of the roller 300, and the guide assembly 700 guides the cable support pulley 500 as it moves. (Reference) Figure 5 Both the linear displacement component 600 and the guide component 700 can be mounted on the base 100, specifically located at the top of the base 100. The two ends of the linear displacement component 600 and the two ends of the guide component 700 are respectively connected to the top ends of the two end supports of the base 100 via a detachable connection.

[0064] like Figure 6 As shown, the linear movement of the cable support pulley 500 along the axial direction of the drum 300 can be achieved through a screw and nut mechanism, and the cable support pulley 500 can be guided during linear movement through a guide rail and slider mechanism. The screw 610 is also driven to rotate by the drive component 200, that is, at this time, the drive component 200 drives both the drum 300 and the screw 610 to rotate.

[0065] The two ends of the lead screw 610 are rotatably supported on the top of the two end supports of the base 100 via bearings and bearing seats. Under the driving action of the drive component 200, the lead screw 610 rotates, and the nut 620 on the lead screw 610 moves linearly. The slider 720 is further connected to the nut 620, and the cable support pulley 500 is fixed to the slider 720. At this time, the slider 720 and the nut 620 move synchronously, so that under the rotation of the lead screw 610, the cable support pulley 500, the slider 720, and the nut 620 move synchronously.

[0066] In some embodiments, the lead screw 610 may be a crescent-shaped reciprocating lead screw, which can convert the unidirectional rotational motion of the lead screw 610 into the reciprocating movement of the nut 620, that is, the lead screw 610 completes the reversal of the nut 620 without changing its rotation direction. Figure 7 This is a schematic diagram of the structure of a lead screw 610 according to an embodiment of this application, as shown below. Figure 7 As shown, the lead screw 610 has a specific pattern of intersecting and closing spiral grooves. At both ends of the stroke, the spiral grooves intersect to guide the crescent pin to smoothly switch from the "outgoing" track to the "return" track.

[0067] In this embodiment, the lead screw 610 is a crescent-shaped reciprocating lead screw, which allows the roller 300 and the lead screw 610 to be driven by the same drive component 200. For example, when the drive component 200 drives the roller 300 to rotate continuously clockwise, the lead screw 610 also rotates continuously clockwise under the drive of the drive component 200; as the lead screw 610 rotates continuously, the nut 620 automatically reverses direction during linear movement based on the crescent-shaped pin structure.

[0068] In some embodiments of this application, the drive component 200 and the lead screw 610 can be transmitted via a belt drive mechanism 800. In one specific embodiment, the linear displacement assembly 600 includes a belt drive mechanism 800, wherein the driving pulley 810 and the driven pulley 820 of the belt drive mechanism 800 are respectively connected to the output shaft of the drive component 200 and the lead screw 610. Figure 3 and Figure 4 As shown, the driving pulley 810 is mounted on the output shaft of the drive component 200 or the rotating shaft of the roller 300, while the driven pulley 820 is mounted on the lead screw 610. The transmission belt 830 is sleeved around the driving pulley 810 and the driven pulley 820. As the drive component 200 or the roller 300 rotates, the belt drive mechanism 800 drives the lead screw 610 to rotate synchronously. It is understood that the transmission between the lead screw 610 and the drive component 200 via the belt drive mechanism 800 is only one example. In other embodiments, the lead screw 610 and the drive component 200 may also be transmitted via other mechanisms, such as a chain drive mechanism.

[0069] In some embodiments, the guide assembly 700 includes two spaced and parallel support plates 721, the support plates 721 being located on the side of the slider 720 away from the nut 620, the end of the support plate 721 near the slider 720 being connected to the slider 720, and the two ends of the axle of each cable support pulley 500 being respectively disposed on the two support plates 721.

[0070] like Figure 6 As shown, the support plate 721 is specifically located at the end of the slider 720 away from the nut 620. At this time, the two support plates 721 are spaced apart and parallel. The ends of the two support plates 721 are fixedly connected to the slider 720. The two cable support pulleys 500 are located between the two support plates 721.

[0071] In one embodiment of this application, the roller 300 has a first rotating shaft 321 and a second rotating shaft 322 at both ends. The first rotating shaft 321 and the second rotating shaft 322 are fixedly connected to the roller 300. The first rotating shaft 321 is connected to the output shaft of the drive component 200. The first rotating shaft 321 and the second rotating shaft 322 are respectively sleeved on the outside of the first cable guide component 410 and the second cable guide component 420, and the first rotating shaft 321 and the second rotating shaft 322 are rotatable relative to the first cable guide component 410 and the second cable guide component 420, respectively.

[0072] In this embodiment, the roller 300 is rotatably supported on the base 100 via a first rotating shaft 321 and a second rotating shaft 322. The first rotating shaft 321 and the second rotating shaft 322 are located at the center positions of the ends of the roller 300, respectively, and both the first rotating shaft 321 and the second rotating shaft 322 are fixedly connected to the roller 300. Specifically, the first rotating shaft 321 is fixedly connected to the output shaft of the drive component 200. In this embodiment, the first rotating shaft 321 and the second rotating shaft 322 are rotatable relative to the base 100, and the first rotating shaft 321, the second rotating shaft 322, and the base 100 are specifically connected via bearings and bearing seats.

[0073] Alternatively, the first cable guide component 410 and the second cable guide component 420 can also be respectively disposed at the center position of the end of the roller 300, specifically located in the shaft holes of the first rotating shaft 321 and the second rotating shaft 322. In this embodiment, the first cable guide component 410 and the second cable guide component 420 are coaxially disposed with the first rotating shaft 321 and the second rotating shaft 322, respectively. The first rotating shaft 321 and the second rotating shaft 322 can rotate around the first cable guide component 410 and the second cable guide component 420, respectively. At this time, the first cable guide component 410 and the second cable guide component 420 can be fixed relative to the base 100.

[0074] For example, such as Figure 9 and Figure 10 As shown, the first rotating shaft 321 is connected to the output shaft of the drive component 200, and the first cable guide component 410 is located in the shaft hole of the first rotating shaft 321. At this time, the cable inlet 431 and the cable outlet 432 on the first cable guide component 410 can be located at both ends of the first cable guide component 410 respectively. In this embodiment, the cable inlet 431 and the cable outlet 432 on the cable guide component are coaxially arranged.

[0075] In some other embodiments, the axis of the cable inlet 431 may be perpendicular to the axis of the cable outlet 432. For example, the cable inlet 431 may be located at the end of the cable guide component, and the cable outlet 432 may be located on the side wall of the cable guide component.

[0076] Figure 11 This is a schematic diagram showing the layout of the second cable guide component 420 of a winch according to an embodiment of this application.
