Description

Technical Field

[0001] The utility model relates to the technical field of hoists, and particularly relates to a heavy-duty hoist. Background Art

[0002] Tonne bins have a large capacity and are widely used in industries such as powder making and pharmaceutical manufacturing. They are mainly used for filling materials such as powders. During the use of tonne bins, they need to be switched between different processes. Therefore, a hoist is required to lift and lower the tonne bins to facilitate switching between different processes.

[0003] For the transfer and switching link of tonne bins between different processes, currently used hoists such as electric hoists have problems of low automation level and low lifting efficiency of tonne bins.

[0004] Later, some heavy-duty hoists also appeared. For example, the utility model patent with the publication number CN219279368U discloses a hoist that realizes the insertion, lifting of goods through a frame, a driving mechanism, and a load-carrying mechanism. Although this structure can improve efficiency, in actual use, the tonne bin cannot be firmly fixed, and there is a problem that the tonne bin may fall off during lifting.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The heavy-duty hoist in the embodiment of the present invention realizes the automatic and rapid lifting and transfer of the tonneau through the cooperation of the frame, the lifting frame, the driving device, the fork and the tonneau clamping mechanism.

[0024] As Figure 1 - Figure 5 shown, the heavy-duty hoist includes a frame 1, a lifting frame 2, a driving device 3, a fork 4 and a tonneau clamping mechanism 5. The lifting frame 2 is arranged in the up and down direction of the frame 1 and is slidably connected to the frame 1. The driving device 3 is arranged on the frame 1. The driving device 3 is connected to the lifting frame 2 and can drive the lifting frame 2 to move up and down along the frame 1. The fork 4 is installed on the lifting frame 2. By telescoping the fork 4, it can be inserted into the tonneau, and after clamping the tonneau 6 through the clamping mechanism to fix the tonneau 6, the tonneau 6 can be transferred.

[0025] As Figure 2 - Figure 4 shown, the tonneau clamping mechanism 5 includes a support plate 51 and a clamping assembly. The support plate 51 is connected to the fork 4. There are two clamping assemblies, and the two clamping assemblies are arranged opposite to each other on the support plate 51. The clamping assembly includes a first cylinder 52, a mounting plate 53 and a clamping plate 54. The mounting plate 53 is arranged on the lower side of the support plate 51. A slide rail 55 is arranged on the mounting plate 53. The clamping plate 54 is slidably arranged on the mounting plate 53 through the slide rail 55. The first cylinder 52 is arranged on the mounting plate 53 and is connected to the clamping plate 54. The clamping plate 54 can be driven to move through the first cylinder 52, so as to clamp the tonneau and ensure the safety of the transfer process.

[0026] In some embodiments, the clamping plate 54 is L-shaped, and a wear-resistant pad 56 is arranged on the clamping plate 54, so as to protect the tonneau and avoid damage to the tonneau caused by the clamping plate 54 hitting or knocking.

[0027] In some embodiments, the driving device 3 includes a driving motor 31, a driving shaft 32, a driving chain 33, a first sprocket 34, and a second sprocket 35. The driving motor 31 is disposed on the top of the frame 1. The driving shaft 32 is in transmission connection with the driving motor 31. The first sprockets 34 are disposed at both ends of the driving shaft 32. The second sprockets 35 are spaced apart from the first sprockets 34. The driving chain 33 is wound around the first sprockets 34 and the second sprockets 35. One end of the driving chain 33 is connected to the lifting frame 2, and the other end is provided with a counterweight 36. During actual operation, the driving motor 31 rotates to drive the driving chain 33 to move, thereby causing the lifting frame 2 to move up and down.

[0028] In some embodiments, a first guide rail 11 and a second guide rail 12 are disposed on the side of the frame 1. The first guide rail 11 and the second guide rail 12 are spaced apart. Corresponding first guide wheels 21 and second guide wheels 22 are disposed on the side surface of the lifting frame 2. The first guide wheel 21 is in sliding abutment with the first guide rail 11, and the second guide wheel 22 is in sliding abutment with the second guide rail 12. Through the first guide rail 11 and the second guide rail 12, positioning during the lifting process of the lifting frame 2 is achieved to maintain the stability of lifting.

[0029] In other embodiments, a third guide rail 13 is disposed at the rear of the lifting frame 2. The counterweight 36 is slidably disposed on the third guide rail 13, thereby realizing the guiding of the counterweight 36 and keeping the counterweight 36 stable during the lifting process.

[0030] Working principle:

[0031] During actual use, after the forklift forks 4 extend out, the ton barrel 6 is lifted. At this time, the first cylinder 52 acts to drive the clamping plate 54 to move. After the two clamping plates 54 move relative to each other, the ton barrel 6 can be clamped. Then, the driving motor 31 is used to drive the lifting frame 2 and the forklift forks 4 to lift, thereby lifting the ton barrel 6.

[0032] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention fall within the protection scope of the present invention.
