[0094] like Figures 1 to 23As shown, this embodiment provides a winch, which includes a reel drum mechanism 1, a traction rope mechanism 2, a rope guide mechanism and a frame mechanism 4;
[0095] The traction rope mechanism 2 includes a traction rope 21;
[0096] The traction rope 21 is wound on the reel drum mechanism 1, and the rope guide mechanism is used to guide the rope body 212 of the traction rope 21 when the reel drum mechanism 1 retracts and releases the traction rope 21;
[0097] The reel drum mechanism 1 and the rope guide mechanism are both arranged on the frame mechanism 4 .
[0098] In this embodiment, the reel drum mechanism 1 comprises a reel drum 11, and the outer wall of the reel drum 11 is provided with a traction rope limiting groove 1111 distributed in a spiral shape;
[0099] The rope guide mechanism includes a guide block 31, a convex slider 311 is provided on the outside of the guide block 31, a traction rope guide groove 312 is vertically arranged and runs through the guide block 31, and the entrance end of the traction rope guide groove 312 is arranged toward the traction rope limiting groove 1111;
[0100] A sliding space 5 is provided between the frame mechanism 4 and the reel drum mechanism 1, the guide block 31 is provided in the sliding space 5, and the slider 311 is located in the traction rope limiting groove 1111, and 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 yielding area is also provided at a position adjacent to the exit end of the traction rope guide groove 312 in the frame mechanism 4.
[0101] This structural design can effectively guide the traction rope, ensuring that the traction rope can be in a vertical state under the guidance of the guide block 31 during the process of retracting and releasing, avoiding the occurrence of oblique pulling. At the same time, the setting of the sliding space 5 can ensure that the guide block 31 can move horizontally, and the guide block 31 is also limited so that it can only move within the sliding space 5, avoiding the guide block 31 from tipping over due to the tension, and ensuring the stability of the mechanism operation.
[0102] In this embodiment, the reel drum mechanism 1 further includes a rope end fixing member 12 and an elastic connecting member;
[0103] The rope end fixing member 12 is rotatably arranged on the reel drum, and the elastic connecting member is respectively connected to the reel drum and the rope end fixing member 12, and the elastic connecting member is used to provide a restoring force for the relative movement between the rope end fixing member 12 and the reel drum 11. The traction rope end 211 of the traction rope 21 is fixed on the rope end fixing member 12.
[0104] Through this structural design, the rope end fixing part 12 can provide a certain retreat space for the traction rope 21 through relative rotation with the reel drum 11, thereby preventing the traction rope 21 from detaching from the reel drum due to excessive rotation of the reel drum 11. At the same time, the elastic connecting part provides a reset force for the rope end fixing part 12 to assist in driving the rope end fixing part 12 to reset relative to the reel drum 11, thereby ensuring that the traction rope 21 is better wound around the reel drum 11.
[0105] At the same time, the elastic connector can provide a certain buffer force, so that when the traction rope fixed on the rope end fixing member 12 is subjected to a large pulling force, the rope end fixing member 12 and the reel drum are driven to produce a certain relative rotation, and a certain buffer is provided. This can avoid the traction rope from being completely tightened or rotating in the opposite direction immediately after exceeding the critical state, reduce the problem of the rope end end of the traction rope being easily damaged, and effectively extend the service life of the traction rope.
[0106] In this embodiment, the reel drum includes a traction rope winding portion 111, a driving mechanism docking portion 112 and a connecting plate 113. The traction rope winding portion 111 is coaxially arranged on the outside of the driving mechanism docking portion 112, and the traction rope winding portion 111 is connected to the driving mechanism docking portion 112 through the connecting plate 113 to form a rope end fixing member placement area 14 between the traction rope winding portion 111 and the driving 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 member 12 includes a reel barrel docking portion 121 and a rope end fixing portion 122 . The rope end fixing portion 122 is disposed on the reel barrel docking portion 121 . The reel barrel docking portion 121 in an annular shape is nested in the rope end fixing member placement area 14 .
[0108] In a specific implementation, a first protrusion 1221 and a second protrusion 1222 are provided on one side of the reel barrel docking portion 121 away from the connecting plate 113, the first protrusion 1221 and the second protrusion 1222 are spaced apart by a preset 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, and at the same time, a rope body guide area 123 matching the diameter of the traction rope is provided between the first protrusion 1221 and the second protrusion 1222, and the rope body guide area 123 is adjacent to the rope head clearance area. The specific shapes and sizes of the rope head clearance area and the rope body guide area 123 match the size and shape of the traction rope used by the winch, and are not limited to the illustrated examples.
[0109] like Fig.16As shown, in a preferred embodiment, the first protrusion 1221 is located at the center of the reel drum docking portion 121, the second protrusion 1222 is located at the edge of the reel drum docking portion 121, and the outer edge is arc-shaped, the outer edge length of the second protrusion 1222 is less than one-third of the outer edge of the reel drum docking portion 121, and the first protrusion 1221 except the position facing the second protrusion 1222 is arc-shaped, so that the first protrusion 1221 and the second protrusion 1222 can better guide the part of the rope body of the traction rope close to the rope head end to a certain extent.
[0110] During specific implementation, the traction rope winding portion 111 in the reel drum is cylindrical, and the outer wall of the traction rope winding portion 111 is provided with a spirally distributed traction rope limiting groove 1111 to form a traction rope winding area; at the same time, the traction rope winding portion 111 is provided with a notch on the side close to the rope head fixing piece 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 piece 12 through the traction rope inlet 1112, and be wound around the reel drum along the traction rope limiting groove 1111.
[0111] Such a structural design allows the traction rope to move relative to the reel drum without interference when the reel drum and the rope end fixing member 12 rotate relative to each other.
[0112] Other structures may also be used in other embodiments to achieve corresponding technical effects. For example, the rope end fixing piece 12 may be designed to slightly protrude from the traction rope winding portion 111, so that when the reel drum and the rope end fixing piece 12 rotate relative to each other, the traction rope can move relative to the reel drum without interference, and the present invention is not limited to this illustrated example.
[0113] In this embodiment, the elastic connection member is composed of a return spring 13, and the two ends of the return spring 13 are respectively connected to the connection plate 113 and the reel barrel docking portion 121. In this embodiment, one end of the return spring 13 is arranged in a first spring fixing hole 1131 in the connection plate 113, and the other end of the return spring 13 is arranged in a second spring fixing hole 1211 in the reel barrel docking portion 121, so as to achieve relative connection between the three.
[0114] In this embodiment, a rotation limiting mechanism is further provided between the reel drum and the rope end fixing member 12 to limit the relative rotation angle between the reel drum 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; the pin fixing hole 1132 and the guide groove 1212 are respectively provided on the connecting plate 113 and the reel barrel docking portion 121;
[0116] 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 is concentrically arranged with the traction rope winding part 111 to limit the relative rotation angle between the reel drum and the rope end fixing member 12.
[0117] Through the design of the rotation limiting mechanism, the relative rotation angle between the reel drum and the rope end fixing part 12 can be limited within a certain range, thereby preventing the two from excessive relative rotation and damaging the elastic connecting part. 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.
[0118] The specific arc length of the guide groove 1212 can be designed according to the actual application needs of the user and is not limited to the illustrated example.
[0119] In some of these embodiments, an anti-slip limit module may be further provided on the drive mechanism docking portion 112, and the reel drum docking portion 121 is sleeved on the drive mechanism docking portion 112, and the reel drum docking portion 121 is located between the connecting plate 113 and the anti-slip limit module to prevent the rope end fixing part 12 from falling off when the rope end fixing part 12 and the reel drum 11 rotate relative to each other. In specific implementation, the anti-slip limit 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 portion 112 to form an anti-slip limit module to prevent the rope end fixing part 12 from falling off. Since the specific structure of the anti-slip limit module is not the design focus of this solution, it can be composed of a mechanism in the prior art, and therefore, it will not be described in detail in this application.
[0120] In the present application, the anti-slip limit module is designed to effectively fix the rope end fixing member 12 on the reel drum without interfering with the relative rotation between the rope end fixing member 12 and the reel drum.
[0121] In this embodiment, a notch is provided on one side of the traction rope winding portion 111 close to the rope end fixing piece 12 , and a traction rope inlet 1112 is formed by the notch.
[0122] In this embodiment, the winch further includes a driving mechanism 6, which is disposed on the frame mechanism 4, and an output shaft of the driving mechanism 6 is coaxially connected to the driving mechanism docking portion 112 to drive the reel drum to rotate.
[0123] In this embodiment, the hoist further includes a main control mechanism, and the main control mechanism is arranged on the frame mechanism 4;
[0124] And the main control mechanism is also connected to the driving mechanism to send a driving signal to the driving mechanism.
[0125] In this embodiment, the main control mechanism includes a limit switch module and a controller;
[0126] The limit switch module includes a first limit switch 81 and a second limit switch 82, both of which are arranged on the frame mechanism 4, and the first limit switch 81 and the second limit switch 82 are also connected to the controller, and the guide block 31 can slide between the first limit switch 81 and the second limit switch 82. Through the arrangement of the first limit switch 81 and the second limit switch 82, the limit function can be effectively played to avoid excessive movement of the guide block, resulting in excessive retraction and release of the traction rope.
[0127] In this embodiment, the main control mechanism further includes a control switch module;
[0128] The control switch module includes a first button 83 and a second button 84, and the first button 83 and the second button 84 are connected to the controller respectively. The operator can control the forward and reverse rotation of the driving mechanism through the first button 83 and the second button 84.
[0129] The controller can be composed of a PLC device, a single-chip microcomputer or other device with control functions in the prior art. Since the controller itself does not belong to the design points of this application, it will not be described in detail here.
[0130] In this embodiment, the first limit switch 81 and the second limit switch 82 are used to detect whether the guide block 31 moves 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-retraction and over-release of the traction rope and improving safety.
[0131] In a specific implementation, the first limit switch 81, the second limit switch 82, the first button 83, the second button 84 and the controller can be arranged on the main control component mounting frame. Figure 5 As shown, the controller is not drawn in the figure. 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 by wired connection or wireless connection. It can be designed according to user needs.
[0132] In specific implementation, the first limit switch 81 and the second limit switch 82 can be formed by touch switches in the prior art, and a trapezoidal protrusion structure for triggering the touch switch can be provided on the guide block 31. The touch switch works in conjunction with the guide block 31. When the traction rope is extended or retracted, the traction rope will translate along the axial direction. When it reaches the limit position preset by the user, the trapezoidal protrusion above 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 specific implementation, the structure of the guide block 31 is not limited to this.
[0133] In this embodiment, the frame mechanism 4 includes a base 41, a first side plate 42, a sliding space cover plate 44, a main control mechanism mounting frame 43 and a bottom plate 45; the driving mechanism 6 includes a mounting seat 61, a driver 62 and a driving shaft 63;
[0134] The driving mechanism 6 is connected to the base 41 through the mounting seat 61, and the mounting seat 61 is used to carry the driver 62. The output end of the driver 62 is connected to the driving shaft 63. The output shaft formed by the driving shaft 63 is coaxially connected to the reel drum 11.
[0135] The main control mechanism mounting frame 43 is used to mount the main control mechanism;
[0136] The base 41 includes a reel drum mechanism docking portion 411 and a rope guide mechanism bearing portion 412;
[0137] The reel drum mechanism docking portion is located in the base 41 at a position facing the reel drum mechanism 1;
[0138] The rope guide mechanism bearing part is adjacent to the reel drum mechanism docking part, and a yielding groove 413 of a preset length is provided on the rope guide mechanism bearing part, and the yielding groove 413 constitutes the traction rope yielding area;
[0139] The first side plate 42 is connected to the bearing part of the rope guide mechanism, and the first side plate 42 is spaced apart from the docking part of the reel drum mechanism by a preset distance, the main control assembly mounting frame is mounted on the first side plate 42, and the main control assembly mounting frame is spaced apart from the bearing part of the rope guide mechanism by a preset distance;
[0140] The sliding space 5 is formed by the space enclosed by the reel drum, the rope guide mechanism bearing portion, the first side plate 42 and the main control component mounting frame.
[0141] In a specific implementation, the reel is coaxially connected to the output shaft formed by the drive shaft 63 by a key connection. Figure 5As shown, the middle of the reel drum is provided with a through hole for matching and connecting with the output shaft formed by the drive shaft 63, and a keyway 1122 is provided in the through hole on the reel drum. When actually implemented, the drive shaft 63 is provided with a corresponding key for matching and connecting with the keyway 1122 (the key is composed of a convex block whose size and shape match the keyway 1122 in the output shaft, which is on the back of the illustrated drive shaft 63. Because the relevant structure belongs to a structure known in the art, therefore, no additional views are drawn in this application to embody it), so as to ensure that the drive shaft 63 can effectively drive the reel drum to rotate. When specifically implemented, the driver 62 can be composed of a motor, and the drive shaft 63 can be composed of the output shaft of the motor or the transmission shaft connected to the output shaft of the motor, so as to realize the control of the start and stop and 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 to embody the relative position relationship between the relevant components and other components, and is not used to embody the specific shape of the mechanism. It can also be composed of a drive mechanism 6 of other structures in the prior art. Since the specific composition structure of the drive mechanism 6 is not the design point of this application, therefore, this application does not repeat its specific composition.
[0142] The driving mechanism is disposed in the base 41 at a position at the first end of the sliding space 5;
[0143] 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.
[0144] The bottom plate 45 is disposed below the base 41 . The bottom plate 45 is located below the load-bearing portion of the rope guide assembly. The bottom plate 45 is also provided with an opening whose shape and size match the clearance groove 413 for the traction rope to pass through.
[0145] In this embodiment, the traction rope assembly includes a traction rope, the groove pitch of the traction rope limiting groove 1111 matches the diameter of the traction rope, the traction rope can be wound around the reel drum along the traction rope limiting groove 1111, and the fixed end of the traction rope is fixed to the reel drum assembly, and the load-bearing end 213 of the traction rope can pass through the traction rope guide groove 312, the traction rope yielding area and the opening on the bottom plate 45 in sequence, thereby ensuring that the rope will not be interfered with during the movement of the guide block 31.
[0146] In this embodiment, the size and shape of the cross section of the sliding space match the size and shape of the cross section of the outer contour of the guide block 31. Through the design of the relevant structure, the stability of the guide can be better guaranteed.
[0147] like Figures 6 to 8As shown, the guide block 31 in this embodiment has an arc surface facing the reel drum, which is concentric with the reel drum, and the related slider 311 also has an arc corresponding to the traction rope limiting groove 1111, so as to ensure that the traction rope can be retracted and released more smoothly. At the same time, the slider 311 includes two arc-shaped protrusions, one long and one short, arranged in parallel, wherein the two arc-shaped protrusions surround the traction rope guide groove 312, so as to better guide the traction rope.
[0148] 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 plays a dust-proof function.
[0149] In this embodiment, the hoist further includes a traction rope detection mechanism 7, and the traction rope detection mechanism 7 includes a sleeve assembly 71, an elastic pressing assembly 72 and a detection assembly 73;
[0150] The sleeve assembly 71 includes a sleeve 711, and the sleeve 711 is in a semi-open structure;
[0151] 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 pressing assembly 72, so that the elastic connection end of the sleeve 711 can move in a direction away from the frame mechanism 4 under the action of an external force;
[0152] The detection component 73 is disposed in the frame mechanism 4 at a position capable of detecting the distance between the elastic connection end and the frame mechanism 4 .
[0153] In this embodiment, the elastic connection end includes at least one first through hole 7113;
[0154] The elastic pressing assembly 72 includes at least one group of elastic pressing members, the number of which matches the number of the first through holes 7113, and the elastic pressing members include bolts 721 and elastic elements;
[0155] The bolt 721 passes through the corresponding first through hole 7113 to be connected to the frame mechanism 4, the elastic element is sleeved on the bolt 721, and the elastic element is supported between the end of the bolt 721 and the elastic connecting end, so that the elastic connecting end is elastically connected to the frame mechanism 4.
[0156] In this embodiment, the detection component 73 includes a position detection switch 731 and a controller;
[0157] The position detection switch 731 is disposed between the elastic connection end and the frame assembly, and the position detection switch 731 is connected to the controller.
[0158] In this embodiment, the sleeve assembly 71 further includes a buffer pad 712 . The buffer pad 712 is disposed on a side of the sleeve facing the frame mechanism 4 . The buffer pad 712 is made of a flexible material.
[0159] In this embodiment, the two ends of the sleeve are spaced apart by a preset distance to form a clearance zone 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 zone respectively.
[0160] In specific implementation, the sleeve and the buffer pad 712 can be connected by connecting parts such as pins and bolts 721, or by other connecting methods. The present application does not specifically limit the connection method between the two.
[0161] In this embodiment, the size and shape of the sleeve match the size and shape of the reel drum in the winch where it is located, and the sleeve is wrapped around the outer side of the traction rope in the winch and wound around the reel drum.
[0162] In specific implementation, the sleeve cover is arranged on the outside of the reel drum, and the two ends of the sleeve are fixed on the frame mechanism 4, and the reel drum can rotate relative to the sleeve. The first cover plate 17 and the second cover plate 18 are both arranged on the side of the reel drum. The relevant positions can be referred to Figures 1 to 3 shown.
[0163] In this embodiment, the sleeve can 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. Fig.18 and Fig.19 As shown, the sleeve body 7111 in this embodiment is in an arc shape, and the sleeve connecting portion 7112 is composed of a flat plate structure with both ends of the sleeve body 7111 folded outward, and 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 set.
[0164] 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. Figure 1 As shown, the elastic connection end of the first end of the sleeve is elastically connected to the main control mechanism mounting frame 43 in the frame assembly through the elastic clamping assembly 72, and the sleeve connecting portion 7112 at the second end of the sleeve can be fixedly connected to the base 41 in the frame mechanism 4, and the second end of the sleeve and the frame mechanism 4 can be fixedly connected by bolts 721 or other methods (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, rather than that the rigid connection end of the sleeve cannot be removed from the frame assembly).
[0165] Since when the traction ropes are stacked, the height thereof is significantly different from the height of the traction ropes under normal circumstances, the structural design in the present application enables the elastic connection end of the sleeve to be lifted up when the traction ropes are misplaced and bulge out, thereby triggering the detection component 73, thereby avoiding more problems caused by the operator's inability to promptly detect whether the traction ropes are misplaced.
[0166] At the same time, when the winch is running, if the traction rope 21 is affected by the negative tension and produces a bulge relative to the reel drum, it will also trigger the elastic connection end of the jacking sleeve and trigger the detection component 73, thereby further avoiding the problem of excessive retreat of the traction rope 21 from the reel drum.
[0167] The design of the buffer pad 712 can provide a certain buffer force, so that the sleeve will not be affected by the slight changes in the process of retracting and releasing the traction rope. At the same time, since the buffer pad 712 is a flexible material, the traction rope can be retracted and released more smoothly, reducing the impact of the pressure brought by the sleeve on its retraction and release. In specific implementation, the buffer pad can be made of plastic material, which has a certain wear resistance.
[0168] At the same time, the design of the sleeve assembly 71 can also provide a certain pressure to the traction rope, thereby guiding the traction rope to a certain extent and reducing the occurrence of misalignment.
[0169] In this embodiment, the elastic connection end includes two first through holes 7113;
[0170] The elastic clamping assembly 72 includes two sets of elastic clamping members, and the elastic clamping members include bolts 721 and elastic elements;
[0171] Each of the bolts 721 passes through the corresponding first through hole 7113 to be connected to the frame assembly, the elastic element is sleeved on the bolt 721, and the elastic element is supported between the end of the bolt and the elastic connecting end, so that the elastic connecting end is elastically connected to the frame assembly.
[0172] Among them, corresponding screw holes can be set on the frame assembly so that the bolts 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 connect with 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 connecting end. Therefore, it can be ensured that the sleeve assembly 71 can be well fixed to the frame mechanism 4 during the normal retraction and release of the traction rope. At the same time, when the traction rope is overlapped and misaligned, the sleeve assembly 71 can be lifted up to trigger the detection assembly 73.
[0173] In this embodiment, the elastic element is composed of a spring 722. In other embodiments, an elastic element composed of other structures can also be arranged on the bolt to achieve an elastic connection between the elastic connection end and the frame mechanism 4.
[0174] That is, the relevant elastic pressing assembly 72 can be formed by a spring bolt in the prior art.
[0175] During specific implementation, the size and shape of the sleeve assembly 71 can be matched according to the size and shape of the reel drum of the corresponding winch.
[0176] In this embodiment, the detection component 73 constituted by the position detection switch 731 is arranged between the elastic connection end and the frame mechanism 4, and the position detection switch 731 is connected to the controller. The relevant controller can be connected to the driving mechanism in the winch, and when the position detection switch 731 is triggered, the driving mechanism can be controlled to stop running, or the controller can be connected to an alarm mechanism, so that when the position detection switch 731 is triggered, an alarm prompt can be given in time, so that the operator can shut down the winch in time. The position detection switch 731 is a position switch, which can be composed of a winch in the prior art, and its specific model and type are not limited in this application. Fig.18 As shown, the position detection switch 731 can be arranged between two elastic pressing members.
[0177] Since the outer wall of the reel drum is provided with a spirally distributed traction rope limiting groove 1111, even when the traction rope is not overlapped but tilted to the side where the traction rope is not provided, a height change will occur due to the pressure on the traction rope limiting groove 1111, thereby triggering the detection component 73.
[0178] In this embodiment, the size and shape of the cross section of the sliding space match the size and shape of the cross section of the outer contour of the guide block.
[0179] During specific implementation, the traction rope can be made of a steel wire rope.
[0180] In the winch in the above embodiment, the outer wall of the reel drum is provided with a spirally distributed traction rope limit groove 1111, which is used to guide the traction rope when it is extended or retracted according to the position and direction of the current traction rope on the reel drum, 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 detecting the traction rope in place, so as to avoid the traction rope from being excessively extended or retracted with the reel drum, thereby causing damage to related parts; and the traction rope detection mechanism 7 is used to realize the traction rope anti-falling detection function, so as to avoid the traction rope from being excessively extended or retracted with the reel drum, thereby preventing the traction rope from being excessively extended or retracted, thereby preventing the traction rope from being excessively extended or retracted with the reel drum ... The rope continues to run after it escapes from the track of the reel drum, causing damage to related parts; at the same time, the reel drum mechanism 1 at the fixed end of the traction rope is provided with a rotation margin design, and when the traction rope is at the extreme position of the reel drum, the traction rope is fixed by a rope end fixing member that can rotate relative to the reel drum, and a certain retreat space can be reserved by utilizing the relative rotation of the two to prevent the traction rope from excessively rotating with the rotation of the reel drum, causing it to escape from the reel drum. At the same time, through the setting of the reset spring, the resetting of the rope end fixing member can also be assisted, thereby assisting the traction rope to better wind around the reel drum.
[0181] When in use, the reel drum is wound with a wire rope, and the drive mechanism is rotated to realize the function of retracting and releasing the wire rope. 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 of the reel when it is retracted, and will not be excessively deviated due to external influences when it is released. A traction rope detection mechanism 7 is provided on the outside of the reel drum mechanism 1. The traction rope detection mechanism 7 includes a sleeve assembly 71, an elastic clamping assembly 72 and a detection assembly. The elastic connection end in the sleeve of the sleeve assembly 71 is elastically connected to the frame assembly by an elastic clamping assembly 72, so that the detection assembly can be used to monitor the distance between the elastic connection end and the frame assembly to determine whether the wire rope is out of the traction rope limit groove 1111, resulting in stacking or misalignment, etc., so as to realize the function of anti-detachment monitoring of the wire rope. The reel drum mechanism 1 includes a rope end fixing part 12 and a reel drum which are connected by an elastic connecting part and can rotate with each other. A rotation limiting mechanism is also provided to prevent the traction rope from separating from the reel drum due to negative pressure. That is, when the wire rope is in a no-load or fully retracted state, there can be a certain rotation margin, and through the setting of the reset spring, a certain buffer force can be provided to prevent the wire rope (i.e., the traction rope) from being fully tightened or rotating in the opposite direction immediately after exceeding the critical state, thereby better extending the service life of the traction rope.
[0182] The winch in this embodiment realizes the functions of guiding, in-position detection, and falling-off monitoring during the process of retracting and releasing the traction rope through the design of the mechanical structure and the application of sensors (including the position detection switch 731, the first limit switch 81, and the second limit switch 82). Among them, the traction rope guiding function enhances the stability of the traction rope retraction and release during the use of the device, and effectively prevents the traction rope from easily escaping from the retraction path of the reel drum when the inclination angle of the extended traction rope is too large, causing damage to the traction rope; the in-position detection function can avoid excessive entanglement or release of the wire rope and the reel, thereby avoiding damage to the traction rope and even the entire winch caused by excessive retraction and release; the anti-falling monitoring function of the traction rope reel realized by the traction rope detection mechanism 7 can timely detect the traction rope escaping from the reel drum under certain conditions, thereby stopping the equipment in time, and preventing the traction rope from escaping from the reel drum track and continuing to extend or retract. The stacked or misplaced traction rope will damage the reel drum or the traction rope itself, avoiding further damage and safety problems.
[0183] The winch of the present invention comprises a reel drum mechanism 1, a traction rope mechanism 2, a rope guiding mechanism and a frame mechanism; the traction rope mechanism comprises a traction rope; the traction rope is wound on the reel drum mechanism, and the rope guiding mechanism is used to guide the traction rope when the reel drum mechanism retracts and releases the traction rope; the reel drum mechanism and the rope guiding mechanism are both arranged on the frame mechanism. Through the design of the rope guiding mechanism, the traction rope can be retracted and released according to a predetermined trajectory when the winch retracts and releases the traction rope, avoiding the situation of oblique pulling of the traction rope, reducing the wear of the traction rope and the reel drum, improving the stability of the equipment, and extending the service life of the winch.
[0184] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, 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.
[0185] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
