[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0041] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0042] In the embodiments of this application, 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 indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0043] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0044] See Figures 1 to 5 As shown, this utility model discloses a telescopic lifting device, which is mainly used for transporting heavy brewing auxiliary equipment such as fermentation tanks and stills. The lifting device includes a lifting frame 1, an adjusting mechanism 2, a flipping frame 3, two first clamping components 4 and multiple second clamping components 5.

[0045] Specifically, such as Figure 1 As shown, the hanger 1 is a frame structure, which is usually made of square steel welded together to ensure that its structural strength meets the hoisting requirements. The hanger 1 is equipped with pulleys and / or scissor lift seats (not marked) on both sides and / or at the four corners to achieve a smooth connection with hoisting equipment such as a drum crane, and thereby control the lifting and lowering of the hanger 1.

[0046] In addition, the two sides of the hanger 1, such as the left and right sides, are respectively provided with a first and a second outer frame 11 and 12. The first and second outer frames 11 and 12 are used to connect the two sides of the tilting frame 3, and the two can move closer or further away from each other under the drive of external force, thereby driving the tilting frame 3 to stretch or contract, so as to be compatible with target transfer containers of different sizes, such as pots / fermentation tanks.

[0047] Figure 2As can be seen, the adjusting mechanism 2 is mounted on the hanger 1. This mechanism connects the first and second outer frames 11 and 12 and can drive them to move closer or further apart, thereby achieving an automated adjusting function. In this application, the adjusting mechanism 2 includes a lead screw 21, first and second threaded blocks 22 and 23, and a drive motor 24. The lead screw 21 is arranged along the length of the hanger 1, and its two ends are connected to the hanger 1 through bearing seats 25. The lead screw 21 has two threaded sections (not shown) with opposite thread directions, that is, each of the two threaded sections extends from the middle of the lead screw 21 toward the end. The first and second threaded blocks 22 and 23 are respectively mounted on the corresponding threaded sections and are connected to the first and second outer frames 11 and 12 respectively. The drive motor 24 is mounted on the hanger 1 and is connected to the lead screw 21 for transmission.

[0048] During adjustment, the drive motor 24 is started, and the rotation direction of the lead screw 21 can be selected to control the first and second threaded blocks 22 and 23 to move closer or further apart, thereby driving the first and second outer frames 11 and 12 to move synchronously. For example, the adjustment mechanism 2 can be set as follows: when the drive motor 24 rotates forward, the corresponding first and second outer frames 11 and 12 move closer together, which is the retracted state; when the drive motor 24 rotates in reverse, the corresponding first and second outer frames 11 and 12 move further apart, which is the extended state.

[0049] It is understood that the lead screw 21 of the adjusting mechanism 2 can also have only one thread and be equipped with only one threaded block to control the movement of one of the outer frames 11 and 12, thus achieving the adjusting function. In addition, in some other embodiments, the adjusting mechanism 2 can also be adapted by using linear movement mechanisms such as hydraulic cylinders, electric push rods, and gear rack structures, which are not limited here.

[0050] See Figure 3 As shown, the tilting frame 3 is disposed between the first and second outer frames 11 and 12, and includes first and second telescopic parts 31 and 32 that are slidably connected. The first and second telescopic parts 31 and 32 are both U-shaped components and are arranged opposite each other. Under the drive of the first and second outer frames 11 and 12, they can move closer or further apart along the length of the hanger 1, thereby meeting the fixing requirements of transfer containers of different sizes. In this application, the first telescopic part 31 includes a first swing arm 312 and telescopic beams 311 disposed at both ends of the first swing arm 312; the second telescopic part 32 includes a second swing arm 322 and telescopic sleeves 321 disposed at both ends of the second swing arm 322; wherein, the telescopic sleeves 321 are slidably connected to the telescopic beams 311, thereby forming a telescopic frame structure that can flexibly adjust its own size.

[0051] Figure 4In this design, two first clamping components 4 are respectively disposed inside the first and second telescopic portions 31 and 32, and are respectively connected to the first and second swing arms 312 and 322. The first and second telescopic portions 31 and 32 are symmetrical to each other. This design is often used to fix transfer containers without connecting ears, such as rectangular fermentation tanks. In this application, the first clamping component 4 includes a connecting plate 41, a support block 42, and a limiting frame 43; wherein the support block 42 and the limiting frame 43 are respectively disposed at the bottom and top of the connecting plate 41. In use, the two first clamping components 4 are controlled to move closer to each other to clamp and fix the transfer container without connecting ears.

[0052] Multiple second clamping components 5 are partially disposed below the first telescopic part 31, such as connecting to the telescopic beam 311, and the remainder are disposed below the second telescopic part 32, such as connecting to the telescopic sleeve 321. These multiple second clamping components 5 are spaced apart. This design is often used to fix transfer containers with connecting lugs, such as circular steamers. In this application, the second clamping component 5 includes a clamping plate 51, a drive cylinder 52, and a fixing pin 53. Both sides of the clamping plate 51 have through holes 511. The drive cylinder 52 is located on the outer side of the clamping plate 51. The fixing pin 53 is connected to the piston rod of the drive cylinder 52 and can penetrate through the through holes 511 on both sides of the clamping plate 51 under the control of the drive cylinder 52. In use, the connecting lugs of the transfer container are inserted into the corresponding clamping plate 51. The drive cylinder 52 controls the fixing pin 53 to extend from the through hole 511 on one side of the clamping plate 51 to the through hole 511 on the other side, thereby locking and fixing the transfer container.

[0053] See Figures 1 to 5 As shown, when using the telescopic lifting device of this application, the first clamping assembly 4 / second clamping assembly 5 is selected according to the type of transport container (distinguished by whether or not it has connecting lugs), and the overall size of the lifting device is adjusted according to the size of the transport container. Specifically, the operator can control the first and second outer frames 11 and 12 to move towards each other through the adjusting mechanism 2, and with the help of the first and second telescopic parts 31 and 32 of the tilting frame 3, the first clamping assembly 4 / second clamping assembly 5 is moved closer or further away from each other, so that the first clamping assembly 4 / second clamping assembly 5 is adjusted into position to fix the transport container. Finally, the lifting equipment moves the lifting device together with the transport container to the work area.

[0054] See Figure 2 As shown, in a preferred embodiment, there are two lead screws 21 arranged side by side along the width direction of the hanger 1. This design facilitates uniform force distribution on the first and second outer frames 11 and 12, improving the stability and reliability of their relative movement. Furthermore, a gear synchronization chain 26 is provided between the two lead screws 21, which allows the power of the drive motor 24 to be synchronously transmitted to the two lead screws 21, saving power costs while ensuring synchronized movement on both sides of the first and second outer frames 11 and 12.

[0055] Furthermore, the hanger 1 is provided with a guide groove 13 along its length to guide the movement of the first and second outer frames 11 and 12. Specifically, the first and second outer frames 11 and 12 are respectively provided with first and second sliders 111 and 121 extending into the guide groove 13. The first and second sliders 111 and 121 can slide along the guide groove 13 and can serve as connecting parts and are respectively connected to the first and second threaded blocks 22 and 23.

[0056] Furthermore, the upper end of the guide groove 13 is provided with first and second limiting holes 131 and 132 for the first and second threaded blocks 22 and 23 to pass through, respectively. The first and second limiting holes 131 and 132 are used to limit the maximum expansion and minimum contraction size of the first and second outer frames 11 and 12 to prevent the lifting equipment components from falling off or colliding. In addition, the first and second limiting holes 131 and 132 are also used to guide the first and second threaded blocks 22 and 23, thereby improving the stability of movement.

[0057] See Figure 3 As shown, in a preferred embodiment, grooves 3111 are provided on both the inner and outer surfaces of the telescopic beam 311, and rollers 3211 are provided on both sides of the inner wall of the telescopic sleeve 321. The rollers 3211 and the grooves 3111 are connected in a rolling engagement. This design helps to reduce the friction between the telescopic beam 311 and the telescopic sleeve 321, and improves the smoothness of their sliding. On the other hand, the rollers 3211 and the grooves 3111 also constitute a guide structure, making the telescopic movement more stable.

[0058] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
