[0002] With the development of the national economy and the continuous improvement of industrial modernization, the safety and smooth operation of industrial production lines directly affect the production costs of enterprises, thereby impacting their market competitiveness. Winches, as a convenient traction and hoisting device, are widely used in various fields. Their basic principle is to use human or mechanical power to drive a drum, wind a traction rope, and perform traction work to pull heavy objects. However, existing winches have the following problems:

[0003] When the angle of the extended traction rope is too large, the traction rope is prone to deviating from the expected extension or retraction path. When the traction rope deviates from the expected track on the drum and continues to extend or retract, the stacked or misaligned traction ropes are prone to damaging the drum or the traction rope itself, thereby affecting the life of the winch.

[0007] The sleeve assembly includes a sleeve, which has a semi-open structure;

[0008] The frame assembly is used to support at least the sleeve assembly and the detection assembly;

[0009] At least one end of the sleeve is an elastic connection end, and the elastic connection end is elastically connected to the frame assembly through the elastic clamping component, so that the elastic connection end of the sleeve can move away from the frame assembly under the action of external force.

[0010] The detection component is located in the frame assembly and can detect the position of the distance between the elastic connection end and the frame assembly.

[0011] In the aforementioned winch detection mechanism, the elastic connecting end includes at least one first through hole;

[0012] The elastic clamping assembly includes at least one set of elastic clamping members, the number of which matches the number of the first through holes, and the elastic clamping members include bolts and elastic elements;

[0013] The bolt passes through the corresponding first through hole and is connected to the frame assembly. The elastic element is sleeved on the bolt 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.

[0014] In the aforementioned winch detection mechanism, the elastic element is composed of a spring.

[0015] The aforementioned winch detection mechanism, wherein the detection component includes a position detection switch and a controller;

[0016] The position detection switch is located between the elastic connection end and the frame assembly, and the position detection switch is connected to the controller.

[0017] In the aforementioned winch detection mechanism, the sleeve assembly further includes a buffer pad, which is disposed in the sleeve on the side facing the frame assembly, and the buffer pad is made of a flexible material.

[0018] In the aforementioned winch detection mechanism, the two ends of the sleeve are spaced at a preset distance to form a clearance zone between the two ends of the sleeve.

[0019] In the aforementioned winch detection mechanism, the two ends of the buffer pad extend from the two ends of the sleeve to the clearance area.

[0020] In the aforementioned winch detection mechanism, the first end of the sleeve is an elastic connection end, the second end of the sleeve is a rigid connection end, the first end of the sleeve is elastically connected to the frame assembly through the elastic clamping component, and the second end of the sleeve is fixedly connected to the frame assembly.

[0021] In the aforementioned winch detection mechanism, 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 wrapped around the drum in the winch.

[0022] In the aforementioned winch detection mechanism, the outer wall of the winch drum is provided with spirally distributed traction rope limiting grooves for the traction rope to be wound.

[0023] This utility model also provides a winch, the main feature of which is that the winch includes any of the above-mentioned winch detection mechanisms.

[0024] The aforementioned winch further includes a drum, a traction rope, and a drive mechanism.

This allows the detection assembly to promptly detect changes in the relative position of the sleeve's elastic connection end and the frame assembly caused by the thrust exerted on the sleeve assembly due to changes in the traction rope's height when the rope on the winch drum becomes stacked or misaligned. This prevents the traction rope from continuing to extend or retract after deviating from its intended path on the drum, reducing the risk of damage to the drum or the rope itself due to stacked or misaligned ropes, and extending the equipment's lifespan. Winches equipped with this detection mechanism offer advantages such as high safety and long service life. Attached Figure Description

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] The following will combine Figures 1 to 9 The present application provides further details regarding the winch testing organization and the winch itself.

[0055] like Figure 1 and Figure 2 As shown, this embodiment provides a winch detection mechanism, including a sleeve assembly 1, a frame assembly 3, an elastic clamping assembly 2, and a detection assembly 4;

[0056] The sleeve assembly 1 includes a sleeve 11 and a buffer pad 12. The sleeve 11 has a semi-open structure, and the two ends of the sleeve 11 are spaced apart by a preset distance to form a clearance area between the two ends of the sleeve 11. The buffer pad 12 is disposed in the sleeve 11 on the side facing the frame assembly 3, and the buffer pad 12 is made of a flexible material. The two ends of the buffer pad 12 extend from the two ends of the sleeve 11 to the clearance area.

[0057] In practice, the sleeve 11 and the buffer pad 12 can be connected by connecting parts such as pins and bolts, or by other connection methods. This application does not specifically limit the connection method between the two.

[0058] The frame assembly 3 is at least used to support the sleeve assembly 1 and the detection assembly 4;

[0059] At least one end of the sleeve 11 is an elastic connection end, and the elastic connection end is elastically connected to the frame assembly 3 through the elastic clamping component 2, so that the elastic connection end of the sleeve 11 can move away from the frame assembly 3 under the action of external force.

[0060] The detection component 4 is located in the frame assembly 3 and is able to detect the distance between the elastic connection end and the frame assembly 3.

[0061] In this embodiment, the sleeve 11 may be made of steel, and the sleeve 11 includes a main body portion located in the middle of the sleeve 11 and sleeve connecting portions 112 located at both ends of the sleeve 11, such as... Figure 2 As shown, in this embodiment, the main body 111 of the sleeve is arc-shaped, and the sleeve connecting part 112 is composed of a flat plate structure with both ends of the main body 111 folded outward. The two ends of the sleeve 11 are spaced apart by a preset distance to form a clearance area between the two ends of the sleeve 11 for the frame assembly 3 to be installed.

[0062] In this embodiment, the sleeve connecting portion 112 located at the first end of the sleeve 11 constitutes an elastic connecting end, and the sleeve connecting portion 112 located at the second end of the sleeve 11 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 component mounting bracket 33 in the frame assembly 3 through the elastic clamping assembly 2. Figure 3 and Figure 4 The sleeve connecting part 112 at the second end of the sleeve shown can be fixedly connected to the base 31 in the frame assembly 3. The second end of the sleeve 11 and the frame assembly 3 can be fixedly connected by bolts 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 assembly 3 during the operation of the winch, rather than that the rigid connection end of the sleeve cannot be removed from the frame assembly).

[0063] 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 4, thereby avoiding more problems caused by the operator's inability to detect whether the traction rope is misaligned in time.

[0064] The design of the buffer pad 12 provides a certain amount of cushioning force, preventing the sleeve 11 from being affected by minor changes during the deployment and retraction of the traction rope. Furthermore, because the buffer pad 12 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 11 on its deployment and retraction. In practice, the buffer pad 12 can be made of plastic, which possesses a certain degree of wear resistance.

[0065] Meanwhile, the design of the sleeve assembly 1 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.

[0066] In this embodiment, the elastic connecting end includes two first through holes 113;

[0067] The elastic clamping assembly 2 includes two sets of elastic clamping components, each of which includes a bolt 21 and an elastic element.

[0068] Each of the bolts 21 passes through the corresponding first through hole 113 and is connected to the frame assembly 3. The elastic element is sleeved on the bolt 21 and supports the end of the bolt 21 between the elastic connection end and the elastic connection end, so that the elastic connection end is elastically connected to the frame assembly 3.

[0069] In this embodiment, a corresponding screw hole can be provided on the frame assembly 3 so that the bolt 21 can be connected to the frame assembly 3. In some embodiments, a nut can also be provided on the side of the frame assembly 3 away from the sleeve assembly 1, so that the bolt 21 can pass through the through hole on the frame assembly 3 and be connected to the nut, thereby realizing the connection between the sleeve assembly 1 and the frame assembly 3. At the same time, an elastic element is provided between the end of the bolt 21 and the elastic connection end. Therefore, it can be ensured that the sleeve assembly 1 can be well fixed to the frame assembly 3 during the normal winding and unwinding of the traction rope. At the same time, when the traction rope overlaps or misaligns, the sleeve assembly 1 can be lifted up to trigger the detection component 4.

[0070] In this embodiment, the elastic element is composed of a spring 22. In other embodiments, the elastic element may be composed of other structures and placed on the bolt 21 to realize the elastic connection between the elastic connection end and the frame assembly 3.

[0071] That is, the relevant elastic clamping components can be constructed using spring bolts, which are already in use in the technology.

[0072] In practice, the size and shape of the sleeve assembly 1 can be matched with the size and shape of the drum 51 of the corresponding winch.

[0073] In this embodiment, the detection component 4 includes a position detection switch 41 and a controller;

[0074] The position detection switch 41 is located between the elastic connection end and the frame assembly 3, and the position detection switch 41 is connected to the controller. The controller can be connected to the drive mechanism in the winch.

[0075] like Figure 9 As shown, the drive mechanism 6 in this embodiment includes a mounting base 61, a driver 62, and a drive shaft 63. It should be noted that the figure only indicates the relative positional relationship of the relevant components and is not a limitation on the specific structure and shape. In actual applications, the shape and structure of each component are not limited to the structure shown in the figure. The drive mechanism 6 can also be composed of other drive mechanisms in the prior art.

[0076] In this embodiment, the drive mechanism 6 is connected to the base 31 in the frame assembly 3 via the mounting base 61. The mounting base 61 is used to support the driver 62. The output end (i.e., the power 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 51. The driver 62 can receive drive signals from the controller to control the rotation, stop, forward and reverse rotation of the drive shaft. That is, when the position detection switch 41 sends a trigger signal, the driver 62 can control the drive shaft connected to it to stop rotating, reducing the occurrence of the traction rope 7 continuing to be wound and unwound even after it has become misaligned.

[0077] In practical implementation, when the position detection switch 41 is triggered, the drive mechanism can be stopped, or the controller can be connected to an alarm mechanism to provide a timely alarm when the position detection switch 41 is triggered, so that the operator can shut down the winch in time. The position detection switch 41 is a position-triggered switch, which can be constructed using existing switches. When the relative positions of two components change, it can be triggered to switch between open and closed states. This application does not limit its specific model or type. Figure 3 , 7As shown, the position detection switch 41 can be located between the two elastic clamping members, and simultaneously between the sleeve connection part 112 and the main control component mounting bracket 33, so that when the relative position of the sleeve connection part 112 and the main control component mounting bracket 33 changes, the position detection switch 41 can be triggered in time to control the driver 62 in the drive mechanism 6 to stop running.

[0078] In this embodiment, the size and shape of the sleeve assembly 1 match the size and shape of the drum 51 in the winch in which it is located, and the sleeve 11 covers the outside of the traction rope in the winch and wound on the drum 51.

[0079] The outer wall of the reel 51 is provided with spirally distributed traction rope limiting grooves 511 for the traction rope to be wound. Because the outer wall of the reel 51 is provided with spirally distributed traction rope limiting grooves 511, even when the traction ropes are not overlapping but tilted to the side where there are no traction ropes, they will still change in height due to pressing on the traction rope limiting grooves 511, thereby triggering the detection component 4.

[0080] The winch detection mechanism in this embodiment can effectively detect whether the traction rope is stacked or misaligned, avoiding the problem of the traction rope being extended or retracted even when it deviates from the expected trajectory on the drum 51. This reduces the risk of the traction rope being easily damaged by the drum 51 or the traction rope itself due to misalignment, and improves the safety and service life of the equipment.

[0081] like Figures 3 to 8 As shown, this utility model also provides a winch, including the winch detection mechanism, the drum 51, the traction rope, the rope guide assembly and the drive mechanism; in this embodiment, the frame assembly 3 of the winch, in addition to the main control assembly mounting frame 33, also includes a base 31, a first side plate 32, a sliding space cover plate 34 and a bottom plate 35.

[0082] The drive mechanism is mounted on the base 31 of the frame assembly 3, and the drive mechanism is connected to the detection assembly 4;

[0083] The output shaft of the drive mechanism is coaxially connected to the reel drum 51, and the drive mechanism drives the reel drum 51 to rotate through the output shaft;

[0084] The traction rope is wound around the reel drum 51;

[0085] The sleeve assembly 1 is connected to the frame assembly 3 through both ends of the sleeve 11. One end of the sleeve 11 is connected to the main control component mounting bracket 33 of the frame assembly 3, and the other end of the sleeve 11 is connected to the base 31. The reel drum 51 is located in the space formed by the sleeve assembly 1 and the frame assembly 3, and the sleeve assembly 1 is in contact with the traction rope located on the reel drum 51.

[0086] In specific implementation, the base 31 includes a roller assembly docking part and a rope guide assembly bearing part, and the base plate 35 can be located below the rope guide assembly bearing part. Both the bottom of the rope guide assembly bearing part and the bottom of the base plate 35 are provided with clearance grooves 313.

[0087] The rope guiding assembly includes a guide block 8, which is used to vertically guide the winding and unwinding of the traction rope 7. The guide block 8 is located within the sliding space formed between the frame assembly 3 and the reel drum 51. Figure 8 As shown, the guide block 8 has a raised slider 811 on its outside and a vertically arranged traction rope guide groove 812 that runs through it inside the guide block 8. The entrance end of the traction rope guide groove 812 is set towards the traction rope limiting groove 511.

[0088] The rope guide assembly bearing part is adjacent to the reel assembly docking part, and the rope guide assembly bearing part is provided with a preset length of clearance groove 313, which constitutes the traction rope clearance area for the traction rope to pass through.

[0089] like Figure 3 As shown, the first side plate 32 is connected to the rope guide assembly bearing part, and the first side plate 32 is spaced apart from the reel assembly docking part by a preset distance. The main control component mounting bracket 33 is disposed on the first side plate 32, and the main control component mounting bracket 33 is spaced apart from the rope guide assembly bearing part by a preset distance.

[0090] The sliding space is formed by the space enclosed by the spool 51, the rope guide assembly bearing part, the first side plate 32 and the main control assembly mounting frame 33, allowing the guide block in the rope guide assembly to slide within it and guide the traction rope.

[0091] Since the specific operating principle of guide block 8 is not the design focus of this solution, its specific design and operating principle will not be described in detail in this application.

[0092] The main control component mounting bracket 33 is used to install the main control component. In addition to the detection component 4 in the winch detection mechanism, the main control component also includes a limit switch module and a control switch module.

[0093] The base 31 includes a reel assembly docking part and a rope guide assembly bearing part;

[0094] The coupling portion of the roller assembly is located in the base 31 facing the roller assembly 5; for example Figure 3 As shown, in a specific implementation, the reel assembly may also be provided with a first cover plate 512 and a second cover plate 513. The first cover plate 512 and the second cover plate 513 can respectively cover the reel 51, thereby providing protection, dust prevention and preventing the reel from moving axially relative to the output shaft.

[0095] The limit switch module includes a first limit switch and a second limit switch, both of which are mounted on the frame assembly 3 and connected to the controller. The guide block can slide between the first and second limit switches. The design of the first and second limit switches allows for the detection of the guide block's position and prevents it from moving beyond its limit positions.

[0096] The control switch module includes a first button and a second button, which are respectively connected to the controller. The user can control the start and stop of the drive mechanism using the first and second buttons, thereby controlling the rotation of the reel drum.

[0097] In specific implementation, the driver 62 can be composed of existing driving devices such as motors, and the output shaft of the drive shaft 63 can be composed of the output shaft of a motor or a transmission shaft connected to the output shaft of a motor, so as to realize the control of the rotation start and stop and forward and reverse rotation of the reel drum 51. The reel drum is also provided with a keyway 5112 in the middle, which can cooperate with the key provided on the drive shaft 63 in the drive mechanism to achieve key connection between the two.

[0098] In practical implementation, the first limit switch, the second limit switch, the first button, and the second button are all connected to the driver 62.

[0099] A winch equipped with the aforementioned winch testing mechanism can also reduce the risk of damage to the drum or the winch itself caused by misalignment of the traction rope, thereby improving the safety and service life of the equipment.

[0100] The beneficial effects of this utility model's winch detection mechanism and the winch itself are as follows:

[0101] This winch detection mechanism comprises a sleeve assembly, a frame assembly, an elastic clamping assembly, and a detection assembly. The sleeve, with its semi-open structure, connects to the frame assembly, and the detection assembly is positioned between the elastic connection end, fixed by the elastic clamping assembly, and the frame assembly. This allows the detection assembly to promptly detect changes in the relative position of the sleeve's elastic connection end and the frame assembly caused by the thrust exerted on the sleeve assembly due to changes in the traction rope's height when the traction rope on the drum becomes stacked or misaligned. This prevents the traction rope from continuing to extend or retract after detaching from its intended trajectory on the drum, reducing the risk of damage to the drum or the traction rope itself caused by stacked or misaligned ropes. It effectively monitors the traction rope's trajectory on the drum, extending the equipment's lifespan. Winches equipped with this detection mechanism can effectively monitor traction rope detachment, promptly detecting traction rope detachment from the drum under certain conditions, stopping the equipment immediately to prevent further damage and safety issues. It boasts advantages such as high safety and long service life.

[0102] 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.

[0103] In the winch detection mechanism and winch technical solution of this utility model, each functional module and module unit can correspond to a specific hardware circuit in an 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 simply by improving 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.

[0104] 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.
