Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, specifically relating to an anti-sway lifting device. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope (traction rope) or chain to lift or pull objects. Winches can lift objects vertically, and pull them horizontally or at an angle. For example, they can be used to pull transport vehicles or objects horizontally or at an angle, and to lift or suspend objects vertically.

[0003] However, the steel wire ropes or chains used are generally "soft," meaning they can bend and swing. When used horizontally or at an angle, the friction between the object and the ground or other surfaces limits the tautness of the steel wire ropes or chains, preventing them from causing the object to swing. However, when lifting an object vertically (in the height direction), because the drum is cylindrical, the steel wire rope or chain naturally droops due to its own weight, remaining vertical. At this point, the steel wire rope or chain is tangential to the drum surface. When an object is suspended below the steel wire rope or chain, airflow can disrupt the object's center of gravity, causing it to swing in the air. Furthermore, when moving the suspended object horizontally, it will also swing in the air due to inertia. This swinging can cause the steel wire rope or chain to break due to excessive force, and it can also cause the connection between the steel wire rope or chain and the object to break due to excessive force during the swinging process. It can even lead to collisions with other objects during the swinging process, easily causing the object to fall and be damaged, posing a safety hazard. Summary of the Invention

[0004] Based on this, this application provides an anti-sway lifting device to solve the technical problem that when using traction ropes or chains for suspension and lifting, the device is prone to swaying in the air, posing a safety hazard.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows: An anti-sway lifting device, comprising: The outer casing is open at its lower end; A rotating assembly is rotatably disposed within the housing and is capable of rotating along its own axis; the rotating assembly is provided with a turntable portion. A suspension assembly, wherein multiple suspension assemblies are sequentially hinged end to end, and one of the suspension assemblies located at the end is disposed on the turntable portion, and the turntable portion is capable of driving multiple suspension assemblies to wrap around the turntable portion; The suspension assembly is provided with a limiting part, which can block one side of the rotation direction of two adjacent suspension assemblies, so that the two adjacent suspension assemblies stop rotating when they are on the same straight line. A clamping assembly is disposed on the outer shell and can cooperate with the turntable to clamp the suspension assembly into a vertical state.

[0006] Preferably, the housing is provided with a driving part, which is used to drive the rotating assembly to rotate.

[0007] Preferably, the rotating assembly includes a rotating roller rotatably connected inside the housing, and two bearings disposed at both ends of the rotating roller. The two bearings are respectively connected to the side wall of the housing, and the turntable is connected to the rotating roller.

[0008] Preferably, the turntable includes a winding disc and guard plates disposed on both sides of the winding disc. The winding disc is connected to the rotating assembly and located inside the housing. A plurality of the suspension assemblies can be wound around the side of the winding disc and are located between the two guard plates.

[0009] Preferably, the winding disc is a regular polygonal winding disc.

[0010] Preferably, the drive unit includes a motor connected to the housing, and the output shaft of the motor is connected to the rotating roller.

[0011] Preferably, the suspension assembly includes a link, a plurality of links are sequentially hinged end to end, and one of the links at the end is connected to the turntable portion, and the limiting portion is disposed at the end of the link.

[0012] Preferably, the limiting portion includes a stop edge disposed at the end of the connecting rod, wherein the surface of the stop edge near the connecting rod is flush with the surface of the connecting rod.

[0013] Preferably, the pressing assembly includes a telescopic rod connected to the housing, the movable end of the telescopic rod being able to extend into the housing and contact the suspension assembly, and is provided with a fitting portion.

[0014] Preferably, the bonding portion includes a bonding plate, which is parallel to the direction in which the suspension assembly extends out of the housing.

[0015] Compared with the prior art, this application has at least the following advantages: This application provides an anti-sway lifting device. The rotating component drives the turntable to rotate, causing multiple suspension components wound around it to unfold, forming a "suspension chain" for suspending the object. When two adjacent suspension components rotate to the same straight line, the limiting part can limit the two adjacent suspension components, preventing them from continuing to rotate and keeping them in a straight line. The object is suspended on the lowest suspension component, and the center of gravity of the object is located on the side away from the limiting part. Then, the turntable rotates in the opposite direction to lift the object. After the object is suspended, the pressing component approaches the last vertical suspension component on the turntable from the side and presses it. The pressing component and the turntable work together to clamp the suspension components from both sides to keep them vertical. Thus, when the entire device lifts the object and moves it horizontally (the direction of movement is from the suspension component to the side without the limiting part), the "suspension chain" of the "straight rod structure" composed of multiple suspension components and limiting parts will move the object synchronously without swaying. Not only can it prevent objects from swinging in the air when they are suspended, but it can also make the suspended object move synchronously with the entire device when moving horizontally, without shaking or swaying, thus improving the stability of the object during suspension.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please refer to Figures 1 to 10 In one specific embodiment of this application, An anti-sway lifting device, comprising: The outer casing 201 has an open lower end; A rotating assembly is rotatably disposed within the housing 201 and is capable of rotating along its own axis. The rotating assembly is provided with a turntable portion. A suspension assembly, wherein multiple suspension assemblies are sequentially hinged end to end, and one of the suspension assemblies located at the end is disposed on the turntable portion, and the turntable portion is capable of driving multiple suspension assemblies to wrap around the turntable portion; The suspension assembly is provided with a limiting part, which can block one side of the rotation direction of two adjacent suspension assemblies, so that the two adjacent suspension assemblies stop rotating when they are on the same straight line. A clamping assembly is disposed on the housing 201 and can cooperate with the turntable to clamp the suspension assembly into a vertical state.

[0022] The rotating component can be a drum, winch, or other rotatable device or facility. The turntable can be a coil, roller, or other device or facility capable of winding multiple suspension components. The suspension component can be a metal rod, traction rod, or other device or facility capable of suspending objects. The limiting component can be a stop plate, limiter, or other device or facility capable of limiting the rotatable connection between two adjacent suspension components. The clamping component can be a clamping plate, clamping piece, or other device or facility capable of contacting the suspension component from multiple points on the side.

[0023] In use: Initially, multiple suspension components are sequentially connected end-to-end and wound around the turntable. That is, at this time, the turntable drives the multiple suspension components in a "winding-up" state. When lifting or suspending an object, the rotating component drives the turntable to rotate, causing the multiple suspension components wound around it to unfold, forming a "suspension chain" for suspending the object. Because the multiple suspension components are hinged, they rotate relative to each other due to their own weight after unfolding. The multiple suspension components are arranged in a direction perpendicular to the horizontal plane. When two adjacent suspension components rotate to the same straight line, the limiting part can limit the adjacent two suspension components, preventing them from continuing to rotate and keeping them in a straight line until the lowermost suspension component connects to the object, suspending the object on the lowermost suspension component, and ensuring that the object's center of gravity is on the side away from the limiting part. The turntable rotates in the opposite direction to lift the object, causing multiple unfolded suspension components to rotate to a vertical position. A clamping component approaches and presses down on the last vertical suspension component on the turntable from the side. The clamping component and the turntable work together to clamp the suspension components from both sides, keeping them vertical. With the help of the limiting component, multiple suspension components are kept in a vertical straight line, allowing only unidirectional rotation—rotation towards the side away from the limiting component. However, because the object's center of gravity is located away from the limiting component, its swaying tendency remains towards the limiting component. But due to the blocking effect of the limiting component, the multiple suspension components cannot rotate, thus remaining in a straight line. Therefore, when the entire device lifts the object and moves it horizontally (from the suspension components towards the side without the limiting component), the "suspension chain" of the "straight rod-like structure" composed of multiple suspension components and the limiting component will move the object synchronously, preventing swaying.

[0024] Through the above process, not only can the object be prevented from swinging in the air when it is suspended, but also the suspended object can be moved synchronously with the entire device when moving horizontally, without shaking or swaying, thus improving the stability of the object during the suspension process.

[0025] Furthermore, a driving unit is provided on the outer casing 201, which is used to drive the rotating assembly to rotate.

[0026] The drive unit can be a geared motor, a rack and pinion, or other devices and facilities capable of driving the rotating assembly to rotate. In other words, during use, the drive unit enables the rotating assembly to rotate along a horizontal axis, thereby causing the turntable to reciprocate as the rotating assembly rotates in both directions, achieving the process of "winding up" or "unwinding up" multiple suspension components.

[0027] In a preferred embodiment, the drive unit includes a motor 204 connected to the housing 201, and the output shaft of the motor 204 is connected to the roller 203.

[0028] In other words, by opening and closing the motor 204, the output shaft of the motor 204 rotates in both directions, driving the rotating roller 203 to rotate reciprocally. This achieves the process of "winding up" or "unwinding" multiple suspension components by driving the turntable to rotate reciprocally. The motor 204 can be a servo motor, controlling the rotation angle of the output shaft of the motor 204. Thus, when cooperating with the rotation of the regular polygonal winding disc 208 (described below), each rotation of a corresponding angle will cause one side of the winding disc 208 to rotate to the side and maintain a vertical state, allowing the suspension components to abut against that side. Furthermore, a protective cover 211 is provided on the outer casing 201. The protective cover 211 is detachably connected to the outer casing 201 and can cover and protect the motor 204 for protection during daily use.

[0029] Specifically, an embodiment of the rotating component in the above process is provided: The rotating assembly includes a rotating roller 203 rotatably connected inside the housing 201, and two bearings 207 disposed at both ends of the rotating roller 203. The two bearings 207 are respectively connected to the side wall of the housing 201, and the turntable is connected to the rotating roller 203.

[0030] One side of the outer casing 201 is open and detachably connected to a cover 210, which facilitates opening the outer casing 201 during use and allows for maintenance and replacement of internal components such as the rotating roller 203 and suspension components. The two sides of the rotating roller 203 are respectively mounted on the cover 210 and the outer casing 201 via bearings 207. When the power unit (motor 204 mentioned above) drives the rotating roller 203 to rotate along its own axis, the rotating roller 203 can drive the turntable connected to it to rotate together, so that multiple suspension components connected end to end are wound around the turntable. When the turntable rotates in the opposite direction, the multiple suspension components can be unwound from the rotating roller 203.

[0031] Specifically, an embodiment of the turntable section in the above process is provided: The turntable includes a winding disc 208 and guard plates 209 disposed on both sides of the winding disc 208. The winding disc 208 is connected to the rotating assembly and is located inside the housing 201. A plurality of the suspension assemblies can be wound around the side of the winding disc 208 and are located between the two guard plates 209.

[0032] In other words, the winding disc 208 is located in the middle of the rotating assembly (the roller 203 mentioned above), and both sides of the winding disc 208 are detachably connected to guard plates 209. This means that the two guard plates 209 form a space within which the winding disc 208 is located. When multiple suspension components are wound around the winding disc 208, the two guard plates 209 restrict the suspension components (connecting rods 301 mentioned below) from both sides, preventing the suspension components from shifting or swaying, i.e., preventing the suspension components from shifting or swaying along the axis of the roller 203. Furthermore, regardless of whether the suspension components are "winding up" or unwinding, they remain between the two guard plates 209, improving the stability of the suspended object. In other words, in conjunction with the vertical restriction of the limiting part, for example... Figure 3 For example, the limiting part prevents the suspension assembly from swinging forward, and the two guard plates 209 prevent the limiting assembly from swinging left and right. Together, they restrict the unfolded suspension assembly in three directions, making the "suspension chain" formed by the multiple unfolded suspension assemblies more stable and preventing it from shaking or swaying in these three directions.

[0033] Specifically, an embodiment of the suspension assembly in the above process is provided: The suspension assembly includes a link 301, and multiple links 301 are sequentially hinged end to end, with one of the links 301 at the end connected to the turntable portion, and the limiting portion is disposed at the end of the link 301.

[0034] Multiple connecting rods 301 are sequentially hinged end to end to form a "suspension chain". Adjacent connecting rods 301 rotate relative to each other. The first connecting rod 301 at the end is connected to the turntable (winding disc 208 mentioned above). When the rotating roller 203 rotates, it can drive the "suspension chain" to wind around the winding disc 208. When the rotating roller 203 rotates in the opposite direction, the "suspension chain" can unfold from the winding disc 208. The limiting part is set at one end of the connecting rod 301. When two adjacent connecting rods 301 rotate outward to the same straight line, the limiting part will restrict the connecting rod 301 from continuing to rotate, so that the two adjacent connecting rods 301 remain in the same straight line to form a "rod" shape. This keeps the multiple unfolded connecting rods 301 unchanged in the vertical direction. Thus, when the entire device moves the suspended object, the "suspension chain" composed of multiple connecting rods 301 can move synchronously, thereby avoiding swaying. In other words, by using the limiting part, the two hinged connecting rods 301 can only rotate in the direction without the limiting part. So, during winding, the limiting part is located on the side of the connecting rod 301 away from the winding disc 208. The connecting rod 301 can rotate and wind around the winding disc 208 with the adjacent connecting rod 301 in the direction of the rotating roller 203. When the connecting rod 301 unfolds, when the connecting rod 301 rotates to be on the same straight line as the adjacent connecting rod 301, it will be blocked by the limiting part and cannot continue to rotate. At this time, the two adjacent connecting rods 301 are kept on the same straight line. So, when the whole device moves the object in the direction in which the connecting rod 301 can rotate, the limiting part can push the connecting rods 301 that are kept on the same straight line to move, avoiding the situation where the connecting rod 301 rotates and swings in the direction of forward movement due to inertia.

[0035] Specifically, an embodiment of the limiting part in the above process is provided: The limiting part includes a stop 302 disposed at the end of the connecting rod 301, and the surface of the stop 302 near the connecting rod 301 is flush with the surface of the connecting rod 301.

[0036] Reference Figures 8 to 10 The multiple connecting rods 301 are connected end to end and can rotate relative to each other through hinges, while the flange 302 is provided at one end of the connecting rod 301. Figure 10 In the middle, the right end of the left connecting rod 301 is provided with a stop 302, and the left end of the right connecting rod 301 is hinged to the right end of the left connecting rod 301. At this time, the connecting rods 301 are in a state of rotating to the same straight line. At this time, the lower end face of the right connecting rod 301 is in contact with the stop 302 and cannot continue to rotate downward. That is to say, the two adjacent connecting rods 301 can only rotate relative to each other upward. So, in practical applications, Figure 10The connecting rod 301 rotates 90 degrees clockwise, and the rotating roller 203 is located to the right of the uppermost connecting rod 301. The upper end of the uppermost connecting rod 301 is connected to the rotating roller 203. When the rotating roller 203 rotates clockwise, it will drive multiple connecting rods 301 to wrap around the rotating roller 203. Because the connecting rods 301 can rotate relative to the adjacent connecting rods 301 to the right at this time, the counterclockwise rotation of the rotating roller 203 can be used to make multiple connecting rods 301 unfold in sequence, so that multiple unfolded connecting rods 301 are kept in the same straight line. At this time, the forward direction of the entire device is to the right. That is to say, the stop 302 is located to the left of the connecting rod 301. So when moving to the right, the stop 302 pushes the adjacent connecting rods 301 from the left to move, so that multiple unfolded connecting rods 301 keep in a vertical straight line and move to the right without swaying. Thus, when moving to the right, the object remains in a stable state and moves synchronously, making the object more stable when moving to the right.

[0037] In a preferred embodiment: the winding disc is a regular polygonal winding disc. The first connecting rod 301 can be fixed to the winding disc 208, with their surfaces in contact, and the retaining edge 302 located on the side away from the winding disc 208, so as to... Figure 10 For example: Figure 10 The connecting rod 301 rotates 90 degrees clockwise. The rotating roller 203 and the winding disc 208 are located to the right of the uppermost connecting rod 301. When the rotating roller 203 rotates clockwise, the winding disc 208 will drive multiple connecting rods 301 to wind around the winding disc 208. At this time, as the connecting rods 301 wind, they enter the space formed by the two guard plates 209. The width of this space is slightly larger than the width of the connecting rods 301, so that after the connecting rods 301 enter this space, they will not shift in the front-to-back direction, but will wind in a spiral shape. Of course, during winding, they are wound around the winding disc 208. The length of the first coil of connecting rod 301 is less than the length of the second coil of connecting rod 301 wound from the outside onto the first coil of connecting rod 301. Its length can be adjusted according to actual needs, so that multiple connecting rods 301 can be smoothly wound in a spiral shape on the winding disc 208. The polygonal winding disc 208 allows the connecting rods 301 to make surface contact with each other when they are wound together. Compared with direct contact with the roller 203, because the roller 203 is a curved surface and has point contact with the connecting rod 301, the connecting rod 301 is prone to bending. The polygonal winding disc 208 is used to prevent the connecting rod 301 from bending.

[0038] Specifically, an embodiment of the pressing and fixing component in the above process is provided: The pressing assembly includes a telescopic rod 205 connected to the housing 201. The movable end of the telescopic rod 205 can extend into the housing 201 to contact the suspension assembly, and is provided with a fitting part.

[0039] The fitting part can be a clamp, or other device or facility that can contact the side of the connecting rod 301 at multiple points in the vertical direction. A telescopic rod 205 is fixed to the outside of the housing 201. When the movable end of the telescopic rod 205 moves the fitting part closer to the suspension assembly (connecting rod 301), see... Figure 2 In the figure, when the rotating roller 203 rotates clockwise, it can unfold the multiple connecting rods 301 wound on the winding disc 208. The connecting rods 301 hang down by their own weight. When the connecting rod 301 closest to the winding disc 208, that is, the uppermost connecting rod 301, is in a vertical state in the unfolded state, the movable end of the telescopic rod 205 drives the fitting part to contact the side of the connecting rod 301 from the right side and apply pressure to clamp the connecting rod 301 on the winding disc 208. The clamping is completed by the restriction of the winding disc 208 from the left side, so that the connecting rod 301 is kept in a vertical state. Figure 2 In this design, the winding disc 208 is a regular hexagon. This means that every time the winding disc 208 rotates 60 degrees, a connecting rod 301 can be rotated to a vertical position. After each 60-degree rotation, the mating part will press the connecting rod 301 tightly from the right side, while the left side of the connecting rod 301 is also in surface contact with the winding disc 208. By clamping the two surfaces, the connecting rod 301 is kept in a vertical position without changing. The winding disc 208 can be any other regular polygon, which can also meet the requirements.

[0040] In a preferred embodiment, the bonding portion includes a bonding plate 206, which is parallel to the direction in which the suspension assembly extends out of the housing 201.

[0041] The bonding plate 206 is connected to the movable end of the telescopic rod 205. When the rotating roller 203 rotates, the movable end of the telescopic rod 205 retracts, causing the bonding plate 206 to move away from the connecting rod 301, thereby avoiding interference with the rotation of the winding disc 208 and the movement of the connecting rod 301. When the object is lifted and suspended, the movable end extends, causing the bonding plate 206 to contact the side of the connecting rod 301 from the right side to complete the clamping, so that the connecting rod 301 remains in a vertical state and does not swing.

[0042] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
