Therefore, this tool is easy to load and unload heavy objects and has good portability.

[0056] The following is combined with Figures 1 to 8 The present application will be described in detail with reference to specific embodiments. Figure 1 A structural schematic diagram from one perspective of the portable heavy object loading and unloading tool provided in an embodiment of this application; Figure 2 A structural schematic diagram from another perspective of the portable heavy object loading and unloading tool provided in the embodiments of this application; Figure 3 for Figure 2 Schematic diagram of the structure of the adjustment extension component; Figure 4 for Figure 2 Schematic diagram of the structure of the medium-width gear set; Figure 5 for Figure 4 Schematic diagram of the middle plate; Figure 6 for Figure 1 A schematic diagram of the folding structure of a portable heavy-duty loading and unloading tool; Figure 7 for Figure 6 Rear view of the folded portable heavy-duty loading and unloading tool; Figure 8 for Figure 1 Rear view of a portable heavy-duty loading and unloading tool; Figure 9 for Figure 1 A magnified view of part A in the middle.

[0057] This application provides a portable heavy-duty loading and unloading tool, including: a base mounting frame 100, a lifting assembly 200, a loading assembly 300, and a moving assembly 400; the base mounting frame 100 includes a mounting frame 110, an extension frame 120, and an extension drive member 130, the extension frame 120 being slidably connected to the mounting frame 110, one end of the extension drive member 130 being connected to the extension frame 120, and the other end being connected to the mounting frame 110, the extension drive member 130 driving the extension frame 120 to move up and down relative to the mounting frame 110; the lifting assembly 200... It includes at least two rotating members 210, a moving member 220, and a driving member 230. The moving member 220 is sleeved on the rotating member 210. One end of the rotating member 210 is connected to the extension frame 120, and the other end is connected to the mounting frame 110. The moving member 220 is hinged to the load assembly 300. The driving member 230 is used to drive the rotating member 210 to rotate, so that the moving member 220 drives the load assembly 300 to rise and fall along the extension direction of the rotating member 210. The moving assembly 400 is hinged to the mounting frame 110 and is away from the load assembly 300.

[0058] In a specific implementation, one end of the extension drive component 130 is connected to the extension frame 120, and the other end is connected to the mounting frame 110. Both ends of the extension frame 120 are inserted into the mounting frame 110, and the extension frame 120 and the mounting frame 110 are slidably connected. The extension drive component 130 drives the extension frame 120 to rise and fall relative to the mounting frame 110. For example, combined with... Figure 1 and Figure 2 The mounting frame 110 includes a horizontal bar and at least two vertical bars, with the vertical bars spaced apart on the horizontal bar. The two ends of the extension frame 120 are correspondingly inserted into the vertical bars. One end of the rotating member 210 is connected to the extension frame 120, and the other end is connected to the horizontal bar.

[0059] To facilitate the lifting or lowering of heavy objects, the tool also includes a lifting assembly 200. The lifting assembly 200 includes at least two rotating members 210, a moving member 220, and a driving member 230. The moving member 220 is sleeved on the rotating member 210 and rises or falls along the rotating member 210. For example, the moving member 220 is threadedly connected to the rotating member 210, and the driving member 230 drives the rotating member 210 to rotate, causing the moving member 220 to rise or fall along the helical direction of the rotating member 210.

[0060] One end of the rotating member 210 is connected to the extension frame 120, and the other end is connected to the mounting frame 110. The moving member 220 is hinged to the load assembly 300. For example, in combination... Figure 1 and Figure 2In use, rotate the load-bearing assembly 300 so that it moves away from the mounting frame 110. The extension direction of the load-bearing assembly 300 is perpendicular to the extension direction of the mounting frame 110. The load-bearing assembly 300 is used to support heavy objects. For folding and storage, combine... Figure 1 , Figure 2 and Figure 6 The load assembly 300 is rotated so that it moves closer to the mounting frame 110, with the extension direction of the load assembly 300 parallel to the extension direction of the mounting frame 110. The drive member 230 drives the rotating member 210 to rotate, so that the moving member 220 moves the load assembly 300 up and down along the extension direction of the rotating member 210.

[0061] To facilitate the movement and transport of heavy objects or the tool itself, the tool also includes a movable component 400, which is hinged to the mounting frame 110 and positioned away from the load-bearing component 300. In use, the movable component 400 is rotated to move away from the mounting frame 110, with its extension direction perpendicular to the extension direction of the mounting frame 110. For folding and storage, the movable component 400 is rotated to move closer to the mounting frame 110, with its extension direction parallel to the extension direction of the mounting frame 110.

[0062] The portable heavy-load loading and unloading tool in this embodiment provides a supporting base for loading and unloading heavy objects through the base mounting frame 100. The movable component 400 facilitates the movement and transportation of heavy objects or the movement of the tool itself. The lifting component 200 drives the heavy object to rise or fall. The tool uses an extension drive component 130 to drive the extension frame 120 to rise relative to the mounting frame 110 for easy unfolding and use. The drive component 230 drives the rotating component 210 to rotate, causing the movable component 220 to drive the load component 300 to rise or fall along the extension direction of the rotating component 210, thus realizing the raising or lowering of heavy objects for easy loading and unloading. The movable component 400 facilitates the movement and transportation of heavy objects or the movement of the tool itself. After use, the extension drive component 130 drives the extension frame 120 to fall relative to the mounting frame 110, causing the rotating component 210 to be stored inside the mounting frame 110. The rotating load component 300 and the movable component 400 are then rotated closer to the mounting frame 110, achieving folding and storage of the tool, reducing its size and making it easy to carry. Therefore, this tool is convenient for loading and unloading heavy objects and has good portability.

[0063] In some possible implementations, the portable heavy object loading and unloading tool provided in this application includes a rotating component 210 comprising a drive threaded rod 211 and a telescopic threaded tube 212. The drive threaded rod 211 is connected to the extension frame 120, and the telescopic threaded tube 212 is provided with a receiving groove 213. The drive threaded rod 211 is slidably connected to the receiving groove 213, and the moving component 220 is sleeved on the telescopic threaded tube 212.

[0064] In practice, the telescopic threaded tube 212 has the same outer diameter as the driving threaded rod 211. The telescopic threaded tube 212 is provided with a receiving groove 213, and the driving threaded rod 211 is slidably connected to the receiving groove 213. The moving part 220 is sleeved on the telescopic threaded tube 212 and is threadedly connected to the telescopic threaded tube 212. The thread parameters of the telescopic threaded tube 212 and the driving threaded rod 211 are the same.

[0065] For example, in combination Figure 1 , Figure 2 and Figure 9 The threaded portions on the telescopic threaded tube 212 and the drive threaded rod 211 are staggered. The telescopic threaded tube 212 is provided with a receiving groove 213, which is spaced apart from the threaded portion on the telescopic threaded tube 212; correspondingly, the drive threaded rod 211 is provided with a telescopic groove 214, which is spaced apart from the threaded portion on the drive threaded rod 211. The receiving groove 213 is slidably connected to the drive threaded rod 211, and the telescopic threaded tube 212 is slidably connected to the telescopic groove 214.

[0066] In use, the drive member 230 drives the threaded rod 211 and the telescopic threaded tube 212 to rotate, so that the moving member 220 rises along the telescopic threaded tube 212 or the drive threaded rod 211; or, the drive member 230 drives the threaded rod 211 and the telescopic threaded tube 212 to rotate in opposite directions, so that the moving member 220 descends along the telescopic threaded tube 212 or the drive threaded rod 211.

[0067] In some embodiments, the drive threaded rod 211 has a cross-shaped cross section. The rotating member 210 in this embodiment is easily retracted or extended via the drive threaded rod 211 and the telescopic threaded tube 212.

[0068] In some other embodiments, the portable heavy object loading and unloading tool provided in this application includes a drive component 230 comprising at least two sprockets 231, a chain 232, and a motor 233. Each sprocket 231 is correspondingly sleeved on the rotating component 210. The output shaft of the motor 233 is connected to any sprocket 231. The chain 232 meshes with the sprocket 231. The motor 233 drives the rotating component 210 to rotate through the sprockets 231 and the chain 232.

[0069] In practice, each sprocket 231 is fitted onto the rotating component 210, the output shaft of the motor 233 is connected to any sprocket 231, and the chain 232 meshes with the sprocket 231. In this embodiment, the driving component 230 drives any sprocket 231 to rotate via the motor 233, and drives another sprocket 231 to rotate via the chain 232, thus facilitating the driving of the rotating component 210 by the corresponding sprocket 231.

[0070] In some embodiments, the portable heavy-load loading and unloading tool provided in this application includes a loading assembly 300 comprising a connecting portion 310, a width-adjusting gear set 320, and at least two clamping plates 330. The connecting portion 310 is hinged to a rotating member 210. The width-adjusting gear set 320 includes at least two adjusting gear racks 321, a width-adjusting gear 322, and a width-adjusting drive member 323. The width-adjusting drive member 323 is provided with a width-adjusting gear 322. Each adjusting gear rack 321 meshes with a width-adjusting gear 322. The adjusting gear racks 321 are respectively connected to the connecting portion 310. The clamping plates 330 are correspondingly provided with the adjusting gear racks 321. The width-adjusting gear 322 is provided on the connecting portion 310. The width-adjusting drive member 323 drives the width-adjusting gear 322 to rotate, so that the two clamping plates 330 are relatively closer or relatively farther apart.

[0071] In practice, the connecting part 310 is hinged to the rotating member 210. When loading or unloading heavy objects, the connecting part 310 is rotated so that it moves the clamping plate 330 away from the rotating member 210, with the extension direction of the connecting part 310 perpendicular to the extension direction of the rotating member 210. When folding and storing, the connecting part 310 is rotated so that it moves the clamping plate 330 closer to the rotating member 210, with the extension direction of the connecting part 310 parallel to the extension direction of the rotating member 210. The clamping plate 330 is used to support heavy objects.

[0072] To facilitate adjustment of the distance between the two clamping plates 330 to accommodate heavy objects of different sizes, a width-adjusting gear set 320 is provided on the connecting part 310. The width-adjusting gear set 320 includes at least two adjusting gear racks 321, a width-adjusting gear 322, and a width-adjusting drive member 323. The width-adjusting gear 322 is provided on the width-adjusting drive member 323, and each adjusting gear rack 321 meshes with the width-adjusting gear 322. The adjusting gear racks 321 are respectively connected to the connecting part 310, and the clamping plates 330 are correspondingly arranged with the adjusting gear racks 321. The width-adjusting gear 322 is provided on the connecting part 310, and the width-adjusting drive member 323 drives the width-adjusting gear 322 to rotate, so that the two clamping plates 330 are relatively closer or relatively farther apart.

[0073] In some possible implementations, the portable heavy-duty loading and unloading tool provided in this application has auxiliary wheels 331 at the bottom of the clamping plate 330. It should be noted that there can be multiple auxiliary wheels 331, which are spaced apart along the extension direction of the clamping plate.

[0074] In some possible implementations, the portable heavy-duty loading and unloading tool provided in this application includes an extension drive unit 130 comprising at least two extension threaded rods 131, at least two linkage sprockets 132, a linkage chain 133, at least two bevel gears, and an extension drive unit 136. The extension threaded rods 131 are spaced apart on the mounting frame 110 and connected to the extension frame 120. The linkage sprockets 132 are correspondingly sleeved on the extension threaded rods 131, and the linkage chain 133 meshes with the linkage sprockets 132. The extension drive unit 136 is connected to the bevel gears, and the bevel gears are correspondingly arranged with the linkage sprockets 132. The extension drive unit 136 drives the bevel gears to cause the linkage sprockets 132 and the linkage chain 133 to rotate the extension threaded rods 131, thereby causing the extension frame 120 to rise or fall.

[0075] In a specific implementation, one end of the extension threaded rod 131 is connected to the mounting frame 110, and the other end is connected to the extension frame 120. Correspondingly, each of the linkage sprockets 132 is fitted onto the extension threaded rod 131. For example, the linkage sprocket 132 is located at the bottom of the extension threaded rod 131, the linkage chain 133 meshes with the linkage sprocket 132, and a bevel gear is correspondingly positioned with the linkage sprocket 132.

[0076] The output shaft of the extension drive unit 136 is connected to a bevel gear. The extension drive unit 136 drives the bevel gear to rotate the extension threaded rod 131. The extension threaded rod 131 drives the linkage sprocket 132 to rotate. The linkage sprocket 132 drives another extension threaded rod 131 to rotate via the linkage chain 133. Since the extension frame 120 is connected to the extension threaded rod 131, the extension frame 120 can rise or fall. This extension drive unit 130 only needs one extension drive unit 136 to drive two extension threaded rods 131 to rotate, thus realizing the rise or fall of the extension frame 120.

[0077] Furthermore, the portable heavy load handling tool provided in this application includes a first bevel gear 134 and a second bevel gear 135. The first bevel gear 134 is sleeved on the extension threaded rod 131, the second bevel gear 135 meshes with the first bevel gear 134, and the extension drive part 136 is connected to the second bevel gear 135.

[0078] In a specific implementation, the first bevel gear 134 and the second bevel gear 135 mesh with each other. The number of teeth and the inclination angle of the first bevel gear 134 and the second bevel gear 135 can be set according to actual conditions, and this application does not impose any restrictions on this. It should be noted that the first bevel gear 134 is sleeved on the extension threaded rod 131, and the output shaft of the extension drive unit 136 is connected to the second bevel gear 135.

[0079] In some embodiments, the extended drive unit 136 may be a motor, but this application does not limit this.
