Description

Technical Field

[0001] This utility model relates to the field of hoisting machinery, and more particularly to a reel drum mechanism and a winch. Background Technology

[0002] As a convenient and high-performance traction and hoisting device, winches are widely used in industrial production and other fields. They generally have components such as a drive mechanism, a drum mechanism, and a traction rope assembly. The traction rope assembly is wound around the drum mechanism, while the drive mechanism is used to support and drive the drum mechanism to rotate, thereby controlling the winding and unwinding of the traction rope.

[0003] However, in the existing technology, the traction rope assembly is directly fixed to the drum by the rope end. This structure can cause the traction rope to be in a state of no load or negative tension. This may result in the traction rope detaching from the drum after rotating to the bottom, making it difficult for the traction rope to return to its original position, which in turn can easily damage the winch. Utility Model Content

[0004] In order to solve at least one of the problems existing in the prior art as described above, this utility model proposes a reel drum mechanism and winch that can have a certain rotational margin, minimize the risk of the traction rope detaching from the reel drum, have good performance, and have a long service life.

[0005] To achieve the above objectives, the reel drum mechanism and winch of this utility model have the following configuration:

[0006] The main feature of this reel mechanism is that it includes a reel, a rope end fixing member, and an elastic connecting member.

[0007] The rope end fixing member is rotatably mounted on the reel drum, and the elastic connecting member is connected to both the reel drum and the rope end fixing member. The elastic connecting member is used to provide a restoring force for the relative movement of the rope end fixing member and the reel drum.

[0008] In the aforementioned reel mechanism, the rope end fixing member is coaxially nested and connected to the reel, so that the rope end fixing member is rotatably mounted on the reel.

[0009] The aforementioned reel mechanism includes a traction rope winding section, a drive mechanism docking section, and a connecting plate. The traction rope winding section is coaxially disposed on the outside of the drive mechanism docking section, and the traction rope winding section is connected to the drive mechanism docking section through the connecting plate to form a rope end fixing area between the traction rope winding section and the drive mechanism docking section.

[0010] The rope end fixing component includes a reel drum docking part and a rope end fixing part. The rope end fixing part is disposed on the reel drum docking part and is in the form of a ring, which is nested within the rope end fixing component placement area.

[0011] In the aforementioned reel mechanism, both ends of the elastic connector are respectively connected to the connecting plate on the reel and the reel docking portion in the rope end fixing member.

[0012] In the aforementioned reel mechanism, the elastic connecting member is composed of a return spring, and the two ends of the return spring are respectively connected to the connecting plate and the reel docking part.

[0013] In the aforementioned reel mechanism, a rotation limiting mechanism is further provided between the reel and the rope end fixing member to limit the relative rotation angle between the reel and the rope end fixing member.

[0014] The aforementioned reel mechanism, wherein the rotation limiting mechanism includes a guide pin, a pin fixing hole, and a guide groove;

[0015] The pin fixing hole and the guide groove are respectively provided on the connecting plate and the roller drum docking part;

[0016] One end of the guide pin is fixed in the pin fixing hole, and the other end of the guide pin can slide in the guide groove. The guide groove is an arc-shaped groove with a preset arc length and is concentric with the traction rope winding part to limit the relative rotation angle between the reel and the rope head fixing member.

[0017] In the aforementioned reel mechanism, the drive mechanism docking part is provided with an anti-detachment limiting module, the reel docking part is sleeved on the drive mechanism docking part, and the reel docking part is located between the connecting plate and the anti-detachment limiting module.

[0018] In the aforementioned reel drum mechanism, a first protrusion and a second protrusion are provided on the side of the reel drum docking portion away from the connecting plate. The first protrusion and the second protrusion 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 and the second protrusion to form the rope head fixing portion.

[0019] In the aforementioned reel mechanism, a rope guide area matching the diameter of the traction rope is provided between the first protrusion and the second protrusion, and the rope guide area is adjacent to the rope head clearance area.

[0020] In the aforementioned reel mechanism, the traction rope winding portion of the reel is cylindrical, and the outer wall of the traction rope winding portion is provided with spirally distributed traction rope limiting grooves to form a traction rope winding area.

[0021] In the aforementioned reel mechanism, the traction rope winding portion has a notch on the side near the rope head fixing member, and the notch forms the traction rope inlet.

[0022] The aforementioned reel mechanism further includes a first cover plate and a second cover plate. The first cover plate covers the docking portion of the drive mechanism, and the second cover plate covers the rope end fixing area. The rope end fixing is located between the second cover plate and the connecting plate.

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

[0024] The beneficial effects of the reel drum mechanism and winch of this utility model are as follows:

[0025] The reel mechanism in this design includes a reel, a rope end fixing component, and an elastic connector. The rope end fixing component can rotate relative to the reel. The elastic connector is located between the reel and the rope end fixing component. This prevents the traction rope, fixed to the rope end fixing component, from continuously rotating with the reel when subjected to a certain thrust, thus avoiding the problem of it detaching from the reel. Simultaneously, it ensures that after the thrust is removed, the rope end fixing component can rotate back to its original position relative to the reel with the assistance of the elastic connector. This allows the traction rope to be wound more effectively around the reel as needed, ensuring that the traction rope can be retracted and extended as required, thereby preventing winch malfunctions caused by the traction rope detaching from the reel. Winches equipped with this reel mechanism feature more stable performance, longer service life, ease of production, and better adaptability. 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] See Figures 1 to 9 As shown, this embodiment provides a reel mechanism, which includes a reel 1, a rope end fixing member 2, and an elastic connector;

[0055] The rope end fixing member 2 is rotatably mounted on the spool drum 1. The elastic connector is connected to both the spool drum 1 and the rope end fixing member 2. The elastic connector provides a restoring force for the relative movement of the rope end fixing member and the spool drum, so that the rope end fixing member 2 can provide a certain amount of backlash space for the traction rope 5 through relative rotation with the spool drum 1, preventing the traction rope 5 from detaching from the spool drum 1 due to excessive rotation. At the same time, the elastic connector provides a restoring force for the rope end fixing member to assist in restoring the rope end fixing member relative to the spool drum 1, ensuring that the traction rope 5 is better wound around the spool drum 1.

[0056] Meanwhile, the elastic connector also provides a certain amount of buffering force, so that when the traction rope fixed to the rope end fixing member 2 is subjected to a large tension, causing the rope end fixing member 2 and the drum 1 to rotate relative to each other, a certain buffering effect is provided. This avoids 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.

[0057] In this embodiment, the rope end fixing member 2 is coaxially nested and connected with the roller drum 1, so that the rope end fixing member 2 is rotatably disposed on the roller drum 1.

[0058] The reel drum 1 includes a traction rope winding part 11, a drive mechanism docking part 12, and a connecting plate 13. The traction rope winding part 11 is coaxially disposed on the outside of the drive mechanism docking part 12, and the traction rope winding part 11 is connected to the drive mechanism docking part 12 through the connecting plate 13 to form a rope end fixing part placement area 14 between the traction rope winding part 11 and the drive mechanism docking part 12.

[0059] The rope end fixing component 2 includes a spool drum docking part 21 and a rope end fixing part 22. The rope end fixing part 22 is disposed on the spool drum docking part 21, and the annular spool drum docking part 21 is nested within the rope end fixing component placement area 14.

[0060] In some embodiments, the drive mechanism docking part 12 may also be provided with an anti-detachment limiting module. The reel drum docking part 21 is sleeved on the drive mechanism docking part 12, and the reel drum docking part 21 is located between the connecting plate 13 and the anti-detachment limiting module, thereby limiting the rope end fixing member 2 laterally and preventing the rope end fixing member 2 from detaching from the reel drum 1 when rotating relative to the reel drum 1. The anti-detachment limiting module can be composed of a component with a size larger than the inner diameter of the reel drum docking part 21 in the prior art, to limit the rope end fixing member 2. Its specific structure is not a design focus of this application; therefore, its specific composition is not described in this solution. Since the first cover plate 61 and the second cover plate 62 are provided in this application, they can also serve a limiting function. Therefore, in practical applications, the first cover plate 61 and the second cover plate can directly constitute the limiting component without the need for other anti-detachment limiting modules.

[0061] The anti-detachment limiting module design effectively fixes the rope end fixing part 2 to the drum 1 without interfering with the relative rotation between the rope end fixing part 2 and the drum 1.

[0062] In this embodiment, the elastic connector is composed of a return spring 3, whose two ends are respectively connected to the connecting plate 13 on the reel drum and the reel drum docking part 21 in the rope head fixing member 2. In this embodiment, one end of the return spring 3 is disposed in the first spring fixing hole 131 in the connecting plate 13, and the other end of the return spring 3 is disposed in the second spring fixing hole 211 in the reel drum docking part 21, so as to realize the relative connection between the three.

[0063] In specific implementation, the reel drum docking portion 21 has a first protrusion 221 and a second protrusion 222 on the side away from the connecting plate 13. The first protrusion 221 and the second protrusion 222 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 221 and the second protrusion 222 to form the rope head fixing portion 22. At the same time, a rope body guide area 23 matching the diameter of the traction rope is also provided between the first protrusion 221 and the second protrusion 222. The rope body guide area 23 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 23 are matched with the size and shape of the traction rope used by the winch, and are not limited to the illustrated example.

[0064] like Figure 7 and Figure 8 As shown, in a preferred embodiment, the first protrusion 221 is located at the center of the reel-tube docking portion 21, and the second protrusion 222 is located at the edge of the reel-tube docking portion 21, with its outer edge being arc-shaped, as shown. Figure 7 and Figure 8As shown, the length of the outer edge of the second protrusion 222 is less than one-third of the length of the outer edge of the reel drum docking part 21. Except for the position facing the second protrusion 222, the first protrusion 221 is arc-shaped, so that the part of the rope body near the end of the rope can be better wrapped around the second protrusion 222.

[0065] like Figure 4 As shown, in a specific implementation, the traction rope winding part 11 in the reel drum 1 is cylindrical, and the outer wall of the traction rope winding part 11 is provided with spirally distributed traction rope limiting grooves 111 to form a traction rope winding area; at the same time, the traction rope winding part 11 is provided with a notch on the side near the rope head fixing member 2, and the notch forms a traction rope inlet 112, so that the traction rope can enter the traction rope limiting groove 111 from the rope head fixing member 2 through the traction rope inlet 112, and wind around the reel drum along the traction rope limiting groove 111.

[0066] 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 part 2 rotate relative to each other.

[0067] Other embodiments may employ other structures to achieve the corresponding technical effects. For example, the rope end fixing member 2 may protrude slightly beyond the design of the traction rope winding part, so that when the reel and the rope end fixing member 2 rotate relative to each other, the traction rope can move relative to the reel without interference. This is not limited to the example shown in the figure.

[0068] In this embodiment, a rotation limiting mechanism is also provided between the spool and the rope end fixing member 2 to limit the relative rotation angle between the spool and the rope end fixing member 2. This ensures that the rope end fixing member 2 can provide a certain amount of retraction space for the traction rope through relative rotation with the spool, so as to prevent the traction rope from detaching from the spool due to excessive rotation. At the same time, the retraction angle can be controlled to prevent excessive retraction and further improve safety.

[0069] In specific implementation, the rotation limiting mechanism includes a guide pin 4, a pin fixing hole 132, and a guide groove 212;

[0070] The pin fixing hole 132 and the guide groove 212 are respectively provided on the connecting plate 13 and the roller drum docking part 21;

[0071] One end of the guide pin 4 is fixed in the pin fixing hole 132, and the other end of the guide pin 4 can slide in the guide groove 212. The guide groove 212 is an arc-shaped groove with a preset arc length, concentrically arranged with the traction rope winding part 11, to limit the relative rotation angle between the reel and the rope end fixing member 2. The design of the rotation limiting mechanism can limit the relative rotation angle between the reel and the rope end fixing member 2 within a certain range, thereby avoiding excessive relative rotation that could damage 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 111 through the traction rope inlet 112 without bending due to excessive relative rotation.

[0072] The specific arc length of the guide groove 212 can be designed according to the user's actual application needs, and is not limited to the example shown in the figure.

[0073] The reel mechanism further includes a first cover plate 61 and a second cover plate 62. The first cover plate 61 covers the drive mechanism docking portion 12, thereby better securing the rope end fixing member 2 to the reel. The second cover plate 62 covers the rope end fixing member placement area 14, with the rope end fixing member 2 located between the second cover plate 62 and the connecting plate 13. The second cover plate 62 further limits the movement of the traction rope. The design of the first cover plate 61 and the second cover plate 62 also provides a dustproof effect.

[0074] like Figures 10 to 12 As shown, the reel mechanism in this embodiment is adaptable, easy to use, and effectively extends the service life of the traction rope wound on it.

[0075] This utility model also provides a winch, which includes a drum assembly, a rope guide assembly, a frame assembly 8 and a drive assembly 9;

[0076] The roller assembly includes the roller mechanism and sleeve 63 in the above embodiments;

[0077] The rope guiding assembly includes a guide block 71, the outside of which is provided with a protruding slider, and the inside of which is provided with a vertically arranged and penetrating traction rope guide groove 711, the inlet end of which is arranged toward the traction rope limiting groove 111.

[0078] The frame assembly 8 is used to support the reel assembly. A sliding space is provided between the frame assembly 8 and the reel assembly. The guide block 71 is disposed in the sliding space, and the slider is located in the traction rope limiting groove 111. The slider can drive the guide block 71 to move linearly in the sliding space as the reel rotates. A traction rope clearance area is also provided in the frame assembly 8 at a position adjacent to the outlet end of the traction rope guide groove 711.

[0079] Both ends of the sleeve 63 are fixed to the frame assembly 8, such as Figure 11 As shown, the sleeve 63 can be connected to the frame assembly 8 through the fixing mechanism 64, and is sleeved on the outside of the traction rope wound on the reel drum;

[0080] like Figure 13 As shown, in this embodiment, the drive assembly 9 includes a mounting base 91, a driver 92, and a drive shaft 93. It should be noted that... Figure 13 This is merely a schematic diagram showing the relative positions of the relevant components, and is not intended to limit the specific shape and structure of the drive assembly 9. Furthermore, the specific composition and operation of the drive assembly 9 are not the design focus of this application. It can also be constructed using drive mechanisms with other compositions in the prior art. Therefore, this application does not impose specific limitations on the relevant structures.

[0081] In this embodiment, the drive assembly 9 is connected to the base 81 in the frame assembly 8 via the mounting base 91. The mounting base 91 is used to support the driver 92. The output end (i.e., the power output end) of the driver 92 is connected to the drive shaft 93. The drive shaft 93 forms the output shaft in the drive assembly 9 and is coaxially connected to the reel drum 1. The driver 92 is used to receive drive signals to control the forward and reverse rotation, as well as the start and stop of the drive shaft 53.

[0082] In a specific implementation, a keyway 122 can be provided on the inner side wall of the drive mechanism docking part 12, and a corresponding key can be provided on the drive shaft 93 of the drive assembly 9, so that the two are connected by a key.

[0083] In this embodiment, the rack assembly 8 includes a base 81, a first side plate 83, a main control component mounting bracket 83, a sliding space cover plate 84, and a bottom plate 85;

[0084] The reel is mounted on the base 81 via the drive assembly 9;

[0085] The main control component mounting bracket 83 is used to mount the main control component;

[0086] The base 81 includes a reel assembly docking part and a rope guide assembly bearing part;

[0087] The docking part of the roller assembly is located in the base 81 facing the roller assembly;

[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 clearance groove 811 of a preset length, which constitutes the traction rope clearance area.

[0089] The first side plate 83 is connected to the rope guide assembly bearing part, and the first side plate 83 is spaced apart from the reel assembly docking part by a preset distance. The main control component mounting bracket 83 is disposed on the first side plate 83, and the main control component mounting bracket 83 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 reel, the rope guide assembly support, the first side plate 83, and the main control assembly mounting bracket 83.

[0091] The drive component 9 is positioned in the base 81 at the first end of the sliding space;

[0092] The sliding space cover plate 84 is connected to the first side plate 83, and the sliding space cover plate 84 covers the second end of the sliding space;

[0093] The base plate 85 is located below the base 81.

[0094] The traction rope 5 is mounted on the reel drum mechanism. The traction rope head 51 on the traction rope 5 is fixed to the rope head fixing member. The rope body 52 in the traction rope is wound around the reel drum. In specific implementation, the rope body 52 in the traction rope can be made of steel wire rope.

[0095] Because of the aforementioned drum mechanism, the winch with this structure has the characteristics of more stable performance, longer service life, easier production, and better adaptability.

[0096] In the present invention's reel drum mechanism and winch technical solution, each functional module and module unit can correspond to a specific hardware circuit in an integrated circuit structure. Therefore, it only involves improvements to the specific hardware circuit. The hardware part is not merely a carrier for executing control software or computer programs. Thus, 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, the present invention 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.

[0097] 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.

[0098] 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.
