[0090] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0091] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, the term "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0092] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0093] If an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0094] like Figures 1 to 23 As shown, this embodiment provides a winch, which includes a drum mechanism 1, a traction rope mechanism 2, a rope guiding mechanism, and a frame mechanism 4;

[0095] The traction rope mechanism 2 includes a traction rope 21;

[0096] The traction rope 21 is wound around the reel mechanism 1. The rope guiding mechanism is adjacent to the reel mechanism 2, and the rope guiding mechanism includes a traction rope guiding part. The traction rope can pass through the traction rope guiding part. The traction rope guiding part guides the rope body 212 of the traction rope 21 when the reel mechanism 1 winds up and unwinds the traction rope 21.

[0097] Both the reel mechanism 1 and the rope guiding mechanism are mounted on the frame mechanism 4.

[0098] In this embodiment, the roller mechanism 1 includes a roller 11, and the outer wall of the roller 11 is provided with spirally distributed traction rope limiting grooves 1111;

[0099] The rope guiding mechanism includes a guide block 31. The guide block 31 has a protruding slider 311 on its outside and a vertically arranged and penetrating traction rope guide groove 312 inside the guide block 31. The entrance end of the traction rope guide groove 312 faces the traction rope limiting groove 1111. The traction rope guide groove constitutes the traction rope guiding part. In some embodiments, the traction rope guiding part does not necessarily need to be a hole 3 structure. It can also be a semi-enclosed groove structure or other shapes, which only need to perform the function of limiting and guiding the traction rope 21.

[0100] A sliding space 5 is provided between the frame mechanism 4 and the reel drum mechanism 1. The guide block 31 is located in the sliding space 5, and the slider 311 is located in the traction rope limiting groove 1111. The slider 311 can drive the guide block 31 to move linearly in the sliding space 5 as the reel drum 11 rotates. A traction rope clearance area is also provided in the frame mechanism 4 at a position adjacent to the outlet end of the traction rope guide groove 312.

[0101] This structural design effectively guides the traction rope, ensuring it remains vertical under the guidance of the guide block 31 during both retraction and extension, preventing oblique pulling. Simultaneously, the sliding space 5 ensures the guide block 31 can move laterally while also limiting its movement to within this space, preventing it from tipping over due to tension and ensuring the stability of the mechanism.

[0102] In this embodiment, the reel mechanism 1 further includes a rope end fixing member 12 and an elastic connector;

[0103] The rope end fixing member 12 is rotatably mounted on the reel drum. The elastic connecting member is connected to both the reel drum and the rope end fixing member 12. The elastic connecting member provides a restoring force for the relative movement of the rope end fixing member 12 and the reel drum 11. The traction rope end 211 of the traction rope 21 is fixed to the rope end fixing member 12.

[0104] This structural design allows the rope end fixing member 12 to provide a certain amount of retraction space for the traction rope 21 through relative rotation with the drum 11, preventing the traction rope 21 from detaching from the drum 11 due to excessive rotation. At the same time, the elastic connector provides a restoring force to the rope end fixing member 12 to assist in resetting the rope end fixing member 12 relative to the drum 11, ensuring that the traction rope 21 is better wound around the drum 11.

[0105] Meanwhile, the elastic connector provides a certain amount of buffering force, which helps to cushion the situation when the traction rope fixed to the rope end fixing member 12 is subjected to a large tension, causing the rope end fixing member 12 and the drum to rotate relative to each other. This helps to prevent the traction rope from immediately becoming fully taut or rotating in the opposite direction after exceeding the critical state, reducing the problem of easy damage to the rope end and effectively extending the service life of the traction rope.

[0106] In this embodiment, the reel includes a traction rope winding portion 111, a drive mechanism docking portion 112, and a connecting plate 113. The traction rope winding portion 111 is coaxially disposed on the outside of the drive mechanism docking portion 112, and the traction rope winding portion 111 is connected to the drive mechanism docking portion 112 through the connecting plate 113 to form a rope end fixing placement area 14 between the traction rope winding portion 111 and the drive mechanism docking portion 112. The traction rope limiting groove 1111 is located on the outer wall of the traction rope winding portion 111.

[0107] The rope end fixing component 12 includes a reel drum docking part 121 and a rope end fixing part 122. The rope end fixing part 122 is disposed on the reel drum docking part 121, and the annular reel drum docking part 121 is nested within the rope end fixing component placement area 14.

[0108] In specific implementation, the reel drum docking portion 121 has a first protrusion 1221 and a second protrusion 1222 on the side away from the connecting plate 113. The first protrusion 1221 and the second protrusion 1222 are spaced apart by a predetermined distance, and a rope head clearance area matching the size and shape of the rope head end of the traction rope is provided between the first protrusion 1221 and the second protrusion 1222 to form the rope head fixing portion 122. At the same time, a rope body guide area 123 matching the diameter of the traction rope is also provided between the first protrusion 1221 and the second protrusion 1222. The rope body guide area 123 is adjacent to the rope head clearance area. The specific shape and size of the rope head clearance area and the rope body guide area 123 are matched with the size and shape of the traction rope used by the winch, and are not limited to the illustrated example.

[0109] like Figure 16 As shown, in a preferred embodiment, the first protrusion 1221 is located at the center of the reel drum docking portion 121, and the second protrusion 1222 is located at the edge of the reel drum docking portion 121, with its outer edge being arc-shaped. The length of the outer edge of the second protrusion 1222 is less than one-third of the length of the outer edge of the reel drum docking portion 121. Except for the position facing the second protrusion 1222, the first protrusion 1221 is arc-shaped, so that the first protrusion 1221 and the second protrusion 1222 can guide the part of the traction rope near the rope head to a certain extent.

[0110] In specific implementation, the traction rope winding part 111 in the reel drum is cylindrical, and the outer wall of the traction rope winding part 111 is provided with spirally distributed traction rope limiting grooves 1111 to form a traction rope winding area; at the same time, the traction rope winding part 111 is provided with a notch on the side near the rope head fixing member 12, and the notch forms a traction rope inlet 1112, so that the traction rope can enter the traction rope limiting groove 1111 from the rope head fixing member 12 through the traction rope inlet 1112 and be wound around the reel drum along the traction rope limiting groove 1111.

[0111] This structural design allows the traction rope to move relative to the reel drum without interference when the reel drum and the rope head fixing member 12 rotate relative to each other.

[0112] Other embodiments may employ other structures to achieve the corresponding technical effects. For example, the rope end fixing member 12 may be designed to protrude slightly beyond the traction rope winding part 111, so that when the spool and the rope end fixing member 12 rotate relative to each other, the traction rope can move relative to the spool without interference, and is not limited to the example shown in this figure.

[0113] In this embodiment, the elastic connector is composed of a return spring 13, and both ends of the return spring 13 are respectively connected to the connecting plate 113 and the reel drum docking portion 121. In this embodiment, one end of the return spring 13 is disposed in the first spring fixing hole 1131 in the connecting plate 113, and the other end of the return spring 13 is disposed in the second spring fixing hole 1211 in the reel drum docking portion 121, so as to realize the relative connection between the three.

[0114] In this embodiment, a rotation limiting mechanism is also provided between the spool and the rope end fixing member 12 to limit the relative rotation angle between the spool and the rope end fixing member 12.

[0115] In this embodiment, the rotation limiting mechanism includes a guide pin 15, a pin fixing hole 1132, and a guide groove 1212;

[0116] The pin fixing hole 1132 and the guide groove 1212 are respectively provided on the connecting plate 113 and the roller drum docking part 121;

[0117] One end of the guide pin 15 is fixed in the pin fixing hole 1132, and the other end of the guide pin 15 can slide in the guide groove 1212. The guide groove 1212 is an arc-shaped groove with a preset arc length and concentrically arranged with the traction rope winding part 111, so as to limit the relative rotation angle between the reel and the rope head fixing member 12.

[0118] The design of the rotation limiting mechanism can limit the relative rotation angle between the reel drum and the rope head fixing member 12 to a certain range, thereby avoiding excessive relative rotation between the two and damaging the elastic connector. At the same time, it can also ensure that the traction rope can be wound in one direction and then enter the traction rope limiting groove 1111 through the traction rope inlet 1112, without bending due to excessive relative rotation.

[0119] The specific arc length of the guide groove 1212 can be designed according to the user's actual application needs, and is not limited to the example shown in the figure.

[0120] In some embodiments, the drive mechanism docking part 112 may also be provided with an anti-detachment limiting module. The reel drum docking part 121 is sleeved on the drive mechanism docking part 112, and the reel drum docking part 121 is located between the connecting plate 113 and the anti-detachment limiting module to prevent the rope end fixing member 12 from falling off when it rotates relative to the reel drum 11. In specific implementation, the anti-detachment limiting module may be composed of a first cover plate 17 and a second cover plate 18. In other embodiments, other methods may also be used, such as a mechanism that can be fixed on the drive mechanism docking part 112 to form the anti-detachment limiting module to prevent the rope end fixing member 12 from falling off. Since the specific structure of the anti-detachment limiting module is not the focus of this solution, it can be composed of a mechanism in the prior art. Therefore, it will not be described in detail in this application.

[0121] In this application, the anti-detachment limiting module design can effectively fix the rope end fixing member 12 to the drum without interfering with the relative rotation between the rope end fixing member 12 and the drum.

[0122] In this embodiment, the traction rope winding part 111 is provided with a notch on the side near the rope head fixing member 12, and the notch forms the traction rope inlet 1112.

[0123] In this embodiment, the winch further includes a drive mechanism 6, which is mounted on the frame mechanism 4 and is coaxially connected to the drive mechanism docking part 112 by the output shaft of the drive mechanism 6 to drive the drum to rotate.

[0124] In this embodiment, the winch further includes a main control mechanism, which is mounted on the frame mechanism 4;

[0125] Furthermore, the main control mechanism is also connected to the drive mechanism to send drive signals to the drive mechanism.

[0126] In this embodiment, the main control mechanism includes a limit switch module and a controller;

[0127] The limit switch module includes a first limit switch 81 and a second limit switch 82, both of which are mounted on the frame mechanism 4 and connected to the controller. The guide block 31 can slide between the first limit switch 81 and the second limit switch 82. The first limit switch 81 and the second limit switch 82 effectively limit the movement of the guide block, preventing excessive movement of the guide block and thus preventing excessive winding or unwinding of the traction rope.

[0128] In this embodiment, the main control mechanism further includes a control switch module;

[0129] The control switch module includes a first button 83 and a second button 84, which are respectively connected to the controller. The operator can control the forward and reverse rotation of the drive mechanism using the first button 83 and the second button 84.

[0130] The connection between each switch in the limit switch module and the controller in this application can be either wired or wireless.

[0131] The controller can be composed of existing PLC equipment, microcontrollers or other devices with control functions. Since the controller itself is not a key design feature of this application, it will not be described in detail here.

[0132] In this embodiment, the first limit switch 81 and the second limit switch 82 are used to detect whether the guide block 31 has moved to the extreme positions at both ends. If the guide block 31 moves to any extreme position, the corresponding limit switch can provide a signal to the drive mechanism to control the drive mechanism to stop running, thereby avoiding over-winding and over-unwinding of the traction rope and improving safety.

[0133] In practice, the first limit switch 81, the second limit switch 82, the first button 83, the second button 84, and the controller can all be mounted on the main control component mounting bracket. For specific installation details, please refer to [reference needed]. Figure 5 As shown in the figure, the controller is not illustrated. In actual implementation, the first limit switch 81, the second limit switch 82, the first button 83, and the second button 84 can be connected to the controller via either wired or wireless connections. The design can be customized to meet specific user needs.

[0134] In a specific implementation, the first limit switch 81 and the second limit switch 82 can be constructed using existing touch switches, and the guide block 31 can be provided with a trapezoidal protrusion structure for triggering the touch switch. The touch switch works in conjunction with the guide block 31. When the traction rope extends or retracts, the traction rope will move axially. When it reaches the user-preset limit position, the trapezoidal protrusion on the top of the guide block 31 can contact the touch switch. After contact, the touch switch will send a signal to stop the motor from driving the reel drum to rotate. In a specific implementation, the structure of the guide block 31 is not limited to this.

[0135] In this embodiment, the frame mechanism 4 includes a base 41, a first side plate 42, a sliding space cover 44, a main control mechanism mounting frame 43, and a base plate 45; the drive mechanism 6 includes a mounting base 61, a driver 62, and a drive shaft 63.

[0136] The drive mechanism 6 is connected to the base 41 via the mounting base 61. The mounting base 61 is used to support the driver 62. The output end of the driver 62 is connected to the drive shaft 63. The drive shaft 63 forms the output shaft and is coaxially connected to the reel drum 11.

[0137] The main control mechanism mounting bracket 43 is used to mount the main control mechanism;

[0138] The base 41 includes a roller drum mechanism docking part 411 and a rope guide mechanism bearing part 412;

[0139] The docking part of the roller drum mechanism is located in the base 41 facing the roller drum mechanism 1;

[0140] The rope guide mechanism bearing part is adjacent to the reel drum mechanism docking part, and the rope guide mechanism bearing part is provided with a clearance groove 413 of a preset length, which constitutes the traction rope clearance area.

[0141] The first side plate 42 is connected to the rope guide mechanism bearing part, and the first side plate 42 is spaced apart from the reel mechanism docking part by a preset distance. The main control component is mounted on the first side plate 42, and the main control component mounting frame is spaced apart from the rope guide mechanism bearing part by a preset distance.

[0142] The sliding space 5 is formed by the space enclosed by the reel, the rope guide mechanism support, the first side plate 42, and the main control component mounting frame.

[0143] In specific implementation, the reel is coaxially connected to the output shaft formed by the drive shaft 63 using a key connection. For example... Figure 5As shown, the reel drum has a through hole in the middle that connects to the output shaft formed by the drive shaft 63, and a keyway 1122 is provided in the through hole on the reel drum. In actual implementation, the drive shaft 63 is provided with a corresponding key for connecting with the keyway 1122 (the key is formed by a protrusion in the output shaft whose size and shape match the keyway 1122, and it is located on the back of the drive shaft 63 shown in the figure. Since the relevant structure is a structure known in the art, no additional view is shown in this application). This ensures that the drive shaft 63 can effectively drive the reel drum to rotate. In specific implementation, the driver 62 can be a motor, and the drive shaft 63 can be the output shaft of the motor or a transmission shaft connected to the output shaft of the motor, so as to realize the control of the start and stop of the rotation and the forward and reverse rotation of the reel drum. At the same time, it should be noted that the drive mechanism 6 in the figure is only used to show the relative positional relationship between the relevant components and other components, and is not used to show the specific shape of the mechanism. It can also be composed of other drive mechanisms 6 in the prior art. Since the specific composition of the drive mechanism 6 is not the design point of this application, its specific composition will not be described in detail in this application.

[0144] The drive mechanism is located in the base 41 at the first end of the sliding space 5;

[0145] The sliding space cover plate 44 is connected to the first side plate 42, and the sliding space cover plate 44 covers the second end of the sliding space.

[0146] The base plate 45 is located below the base 41 and below the rope guide assembly bearing part. The base plate 45 also has an opening with a shape and size that matches the relief groove 413 for the traction rope to pass through.

[0147] In this embodiment, the traction rope assembly includes a traction rope. The groove spacing of the traction rope limiting groove 1111 matches the diameter of the traction rope. The traction rope can be wound around the reel along the traction rope limiting groove 1111, and the fixed end of the traction rope is fixed to the reel assembly. The load-carrying end 213 of the traction rope can pass through the traction rope guide groove 312, the traction rope clearance area, and the opening on the base plate 45 in sequence, thereby ensuring that the rope will not be interfered with during the movement of the guide block 31.

[0148] In this embodiment, the dimensions and shape of the cross-section of the sliding space match the dimensions and shape of the cross-section of the outer contour of the guide block 31. Through the design of this structure, the stability of the guide can be better guaranteed.

[0149] like Figures 6 to 8As shown, in this embodiment, the guide block 31 has an arc surface concentric with the reel cylinder on the side facing the cylinder, and the related slider 311 also has an arc corresponding to the traction rope limiting groove 1111, thereby ensuring smoother winding and unwinding of the traction rope. Simultaneously, the slider 311 includes two parallel arc-shaped protrusions, one long and one short, which surround the traction rope guide groove 312, thus better guiding the traction rope.

[0150] In this embodiment, the design of the sliding space cover plate 44 can further prevent the guide block 31 from leaving the sliding space, and also serves as a dustproof function.

[0151] In this embodiment, the winch further includes a traction rope detection mechanism 7, which includes a sleeve assembly 71, an elastic clamping assembly 72, and a detection assembly 73.

[0152] The sleeve assembly 71 includes a sleeve 711, which has a semi-open structure;

[0153] At least one end of the sleeve 711 is an elastic connection end, and the elastic connection end is elastically connected to the frame mechanism 4 through the elastic clamping assembly 72, so that the elastic connection end of the sleeve 711 can move away from the frame mechanism 4 under the action of external force.

[0154] The detection component 73 is located in the frame mechanism 4 and can detect the distance between the elastic connection end and the frame mechanism 4.

[0155] In this embodiment, the elastic connection end includes at least one first through hole 7113;

[0156] The elastic clamping assembly 72 includes at least one set of elastic clamping members, the number of which matches the number of the first through holes 7113, and the elastic clamping members include bolts 721 and elastic elements;

[0157] The bolt 721 passes through the corresponding first through hole 7113 and is connected to the frame mechanism 4. The elastic element is sleeved on the bolt 721 and supports the end of the bolt 721 between the elastic connection end and the elastic connection end, so that the elastic connection end is elastically connected to the frame mechanism 4.

[0158] In this embodiment, the detection component 73 includes a position detection switch 731 and a controller;

[0159] The position detection switch 731 is located between the elastic connection end and the frame assembly, and the position detection switch 731 is connected to the controller.

[0160] In this embodiment, the sleeve assembly 71 further includes a buffer pad 712, which is disposed in the sleeve on the side facing the frame mechanism 4, and the buffer pad 712 is made of a flexible material.

[0161] In this embodiment, the two ends of the sleeve are spaced apart by a preset distance to form a clearance area between the two ends of the sleeve; the two ends of the buffer pad 712 extend from the two ends of the sleeve to the clearance area.

[0162] In practice, the sleeve and the buffer pad 712 can be connected by connecting parts such as pins and bolts 721, or by other connection methods. This application does not specifically limit the connection method between the two.

[0163] In this embodiment, the size and shape of the sleeve match the size and shape of the drum in the winch in which it is located, and the sleeve covers the outside of the traction rope in the winch and wound around the drum.

[0164] In practice, the sleeve cover is located on the outside of the reel drum, and both ends of the sleeve are fixed to the frame mechanism 4, allowing the reel drum to rotate relative to the sleeve. The first cover plate 17 and the second cover plate 18 are both located on the side of the reel drum; their positions can be found in [reference needed]. Figures 1 to 3 As shown.

[0165] In this embodiment, the sleeve may be made of steel, and the sleeve includes a sleeve body portion 7111 located in the middle of the sleeve and sleeve connecting portions 7112 located at both ends of the sleeve, such as... Figure 18 and Figure 19 As shown, in this embodiment, the main body 7111 of the sleeve is arc-shaped, and the sleeve connecting part 7112 is composed of a flat plate structure with both ends of the main body 7111 folded outward. The two ends of the sleeve are spaced apart by a preset distance to form a clearance area between the two ends of the sleeve for the frame assembly to be installed.

[0166] In this embodiment, the sleeve connecting portion 7112 located at the first end of the sleeve constitutes an elastic connecting end, and the sleeve connecting portion 7112 located at the second end of the sleeve constitutes a rigid connecting end, such as... Figure 1 As shown, the elastic connection end of the first end of the sleeve is elastically connected to the main control mechanism mounting bracket 43 in the frame assembly through the elastic clamping component 72, while the sleeve connection part 7112 of the second end of the sleeve can be fixedly connected to the base 41 in the frame mechanism 4. The second end of the sleeve and the frame mechanism 4 can be fixedly connected by bolts 721 or other means (it should be noted that the fixed connection mentioned here means that there will be no relative displacement between the rigid connection end and the frame mechanism 4 during the operation of the winch, and does not mean that the rigid connection end of the sleeve cannot be removed from the frame assembly).

[0167] Since the height of the traction rope when it is stacked is significantly different from the height of the traction rope under normal circumstances, the structural design in this application can push up the elastic connection end of the sleeve when the traction rope is misaligned and protrudes, triggering the detection component 73, thereby avoiding more problems caused by the operator's inability to detect whether the traction rope is misaligned in time.

[0168] Meanwhile, when the winch is running, if the traction rope 21 is subjected to negative tension and protrudes relative to the drum, it will also trigger the elastic connection end of the lifting sleeve and trigger the detection component 73, thereby further preventing the problem of the traction rope 21 retracting excessively and detaching from the drum.

[0169] The design of the buffer pad 712 provides a certain amount of cushioning force, preventing the sleeve from being affected by minor changes during the deployment and retraction of the traction rope. Furthermore, because the buffer pad 712 is made of a flexible material, it allows for smoother deployment and retraction of the traction rope, reducing the impact of pressure from the sleeve on its operation. In practice, the buffer pad can be made of plastic, which possesses a certain degree of wear resistance.

[0170] Meanwhile, the sleeve assembly 71 is designed to provide a certain amount of pressure to the traction rope, which can guide the traction rope to a certain extent and reduce the occurrence of misalignment.

[0171] In this embodiment, the elastic connecting end includes two first through holes 7113;

[0172] The elastic clamping assembly 72 includes two sets of elastic clamping components, each of which includes a bolt 721 and an elastic element.

[0173] Each of the bolts 721 passes through the corresponding first through hole 7113 and is connected to the frame assembly. The elastic element is sleeved on the bolt 721 and supports the end of the bolt and the elastic connection end, so that the elastic connection end is elastically connected to the frame assembly.

[0174] The frame assembly can be provided with corresponding screw holes so that the bolt can be connected to the frame assembly. In some embodiments, a nut can also be provided on the side of the frame assembly away from the sleeve assembly 71, so that the bolt can pass through the through hole on the frame assembly and be connected to the nut, thereby realizing the connection between the sleeve assembly 71 and the frame mechanism 4. At the same time, an elastic element is provided between the end of the bolt and the elastic connection end. Therefore, it can be ensured that the sleeve assembly 71 can be well fixed to the frame mechanism 4 during the normal winding and unwinding of the traction rope. At the same time, when the traction rope overlaps or misaligns, the sleeve assembly 71 can be lifted up to trigger the detection component 73.

[0175] In this embodiment, the elastic element is composed of a spring 722. In other embodiments, the elastic element may be composed of other structures and placed on the bolt to realize the elastic connection between the elastic connection end and the frame mechanism 4.

[0176] That is, the relevant elastic clamping component 72 can be constructed using spring bolts in the prior art.

[0177] In practice, the size and shape of the sleeve assembly 71 can be matched with the size and shape of the drum of the corresponding winch.

[0178] In this embodiment, the detection component 73, formed by the position detection switch 731, is located between the elastic connection end and the frame mechanism 4, and the position detection switch 731 is connected to the controller. The controller can be connected to the drive mechanism in the winch, and when the position detection switch 731 is triggered, it can control the drive mechanism to stop running. Alternatively, the controller can be connected to an alarm mechanism, so that when the position detection switch 731 is triggered, an alarm can be promptly triggered, allowing the operator to shut down the winch in time. The position detection switch 731 is a position switch, which can be formed using a winch mechanism in the prior art; this application does not limit its specific model or type. Figure 18 As shown, the position detection switch 731 can be positioned between the two elastic clamping members.

[0179] Because the outer wall of the reel drum is provided with spirally distributed traction rope limiting grooves 1111, even when the traction ropes are not overlapping but tilted to the side without traction ropes, they will change in height due to pressing on the traction rope limiting grooves 1111, thereby triggering the detection component 73.

[0180] In this embodiment, the dimensions and shape of the cross-section of the sliding space match the dimensions and shape of the cross-section of the outer contour of the guide block.

[0181] In practice, the traction rope can be made of steel wire rope.

[0182] In the winch of the above embodiment, the outer wall of the drum is provided with spirally distributed traction rope limiting grooves 1111 to determine the position and direction of the traction rope on the drum, achieving a guiding function when the traction rope extends or retracts, so that the traction rope can move along the correct trajectory; at the same time, a first limit switch 81 and a second limit switch 82 are provided to cooperate with the guide block to realize the function of traction rope positioning detection, preventing the traction rope from excessively extending or retracting with the drum, which could damage related components; and the traction rope detection mechanism 7 is used to realize the traction rope anti-derailment detection function to prevent traction If the rope continues to run after detaching from the reel's trajectory, it will damage related components. Meanwhile, the reel mechanism 1 at the end of the traction rope is designed with a rotation margin. When the traction rope is at the limit position of the reel, the traction rope is fixed by a rope end fixing member that can rotate relative to the reel. The relative rotation between the two can leave a certain amount of backlash space to prevent the traction rope from rotating excessively with the rotation of the reel, which would cause it to detach from the reel. At the same time, the setting of the return spring can also provide assistance for the return of the rope end fixing member, thereby helping the traction rope to better wind back onto the reel.

[0183] In application, the wire rope is wound around the reel drum, and the wire rope is wound and unwound by rotating the drive mechanism. The wire rope extends from the bottom of the reel drum, and a rope guide mechanism is set at the exit to ensure that the wire rope enters the correct position on the reel when it is wound up, and does not deviate excessively due to external influences when it is unwound. The reel drum mechanism 1 is equipped with a traction rope detection mechanism 7 on its exterior. The traction rope detection mechanism 7 includes a sleeve assembly 71, an elastic clamping assembly 72, and a detection component. The elastic connecting end of the sleeve in the sleeve assembly 71 is elastically connected to the frame assembly by the elastic clamping assembly 72. Thus, the detection component can monitor the distance between the elastic connecting end and the frame assembly to determine whether the wire rope has detached from the traction rope limiting groove 1111, causing problems such as stacking or misalignment, thereby realizing the function of wire rope anti-detachment monitoring. The reel mechanism 1 includes a rope end fixing member 12 and a reel drum that are rotatable and connected by elastic connectors. It also has a rotation limit mechanism to prevent the traction rope from coming off the reel drum due to negative pressure. That is, when the wire rope is unloaded or fully retracted, there is a certain rotation margin. In addition, the reset spring can provide a certain buffer force to prevent the wire rope (i.e., the traction rope) from becoming fully taut or rotating in the opposite direction immediately after exceeding the critical state, thereby better extending the service life of the traction rope.

[0184] In this embodiment, the winch, through its mechanical structure design and the application of sensors (including position detection switch 731, first limit switch 81, and second limit switch 82), achieves the functions of guiding, detecting, and monitoring the traction rope during its winding and unwinding processes. The traction rope guiding function enhances the stability of the traction rope during operation, effectively preventing it from easily detaching from the retraction path of the drum when the extended traction rope angle is too large, thus avoiding damage to the traction rope. The position detection function prevents excessive entanglement or unwinding of the wire rope from the drum, thereby avoiding damage to the traction rope and even the entire winch caused by excessive winding and unwinding. The traction rope detection mechanism 7's anti-detachment monitoring function for the traction rope drum can promptly detect traction rope detachment from the drum under certain conditions, thereby stopping the equipment in time. This prevents the traction rope from continuing to extend or retract off the drum track, which could lead to stacked or misaligned traction ropes damaging the drum or the traction rope itself, thus preventing further damage and safety issues.

[0185] The winch of this utility model includes a drum mechanism 1, a traction rope mechanism 2, a rope guiding mechanism, and a frame mechanism. The traction rope mechanism includes a traction rope, which is wound around the drum mechanism. The rope guiding mechanism guides the traction rope when the drum mechanism winds in and out. Both the drum mechanism and the rope guiding mechanism are mounted on the frame mechanism. The design of the rope guiding mechanism ensures that the traction rope is wound and unwound along a predetermined trajectory, preventing oblique pulling of the traction rope, reducing wear on the traction rope and drum, improving equipment stability, and extending the winch's service life.

[0186] In the winch technical solution of this utility model, each functional module and module unit can correspond to a specific hardware circuit in the integrated circuit structure. Therefore, it only involves the improvement of the specific hardware circuit. The hardware part is not merely a carrier for executing control software or computer programs. Therefore, solving the corresponding technical problem and obtaining the corresponding technical effect does not involve the application of any control software or computer programs. In other words, this utility model can solve the technical problem and obtain the corresponding technical effect by simply using the improvements in the hardware circuit structure involved in these modules and units, without the need for specific control software or computer programs to achieve the corresponding function.

[0187] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0188] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
