Description

Technical Field

[0001] This application relates to the technical field of equipment for processing and producing baijiu (Chinese liquor), and in particular to a device for hoisting the lid of a steamer. Background Technology

[0002] The distillation of baijiu (Chinese liquor) involves high temperatures, requiring tools to lift the still lid. Currently, most tools for lifting the still lid are simple lever-support structures. When removing the still, the steam pipe is first lifted manually, and then the lid is pried up using a support arm and moved horizontally to its designated position. This method has the following drawbacks and limitations:

[0003] (1) Due to the high temperature of the still, manual operation poses a significant risk of burns and safety hazards. In addition, manual operation is cumbersome, unstable, and inconvenient.

[0004] (2) The steamer lid and the steam pipe need to be transferred in steps, which is inefficient and poses certain safety hazards. For example, when the steam pipe is opened, the air pressure inside the steamer is greater than the external air pressure, and the steam will rush out instantly, which can easily burn the staff. When the steam pipe is transferred, it is easy to collide with the nearby structure. Utility Model Content

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Currently, the removal of the still lid is mostly done manually. However, due to the high temperature of the still, manual operation poses a significant risk of burns and safety hazards. In addition, manual operation is also cumbersome, unstable, and inconvenient.

[0043] Based on this, this application provides a steamer lid hoisting device, which includes:

[0044] Fixed column;

[0045] A rotary mechanism, comprising a rotary column rotatably mounted on a fixed column and a drive assembly for driving the rotary column to rotate;

[0046] The hoisting mechanism includes:

[0047] The first boom is fixed to the slewing column;

[0048] The second boom is rotatably mounted at one end on the slewing column and is driven to rotate by a drive component;

[0049] The hoisting assembly includes a first hoisting rope, a second hoisting rope, and a rope winding structure for winding or unwinding the first and second hoisting ropes, wherein the free end of the first hoisting rope passes through the end of the first boom away from the slewing column, and the free end of the second hoisting rope passes through the end of the second boom away from the slewing column.

[0050] The steamer lid lifting device provided in the above embodiments of this utility model, in use, firstly drives the rotating column to rotate via the drive assembly, moving the first lifting rope on the first lifting arm to directly above the steamer lid. Then, drives the second lifting arm to rotate via the drive component, moving the second lifting rope to directly above the steamer lid's vent pipe. Next, the winding and unwinding structure is activated, simultaneously unwinding the first and second lifting ropes, causing their lower ends to descend to the steamer lid and vent pipe. The first lifting rope connects to the steamer lid, and the second lifting rope connects to the vent pipe. Then, the winding and unwinding structure simultaneously winds up the first and second lifting ropes, thus lifting the steamer lid and vent pipe. Finally, the drive assembly and drive component drive the rotating column and second lifting arm to rotate, placing the steamer lid and vent pipe in the designated position.

[0051] The steamer lid hoisting device in this embodiment can automatically raise and lower the steamer lid and the vent pipe through a rope winding structure, a first hoisting rope, and a second hoisting rope, reducing the labor intensity of workers and improving the efficiency of opening and closing the steamer lid. By driving the rotation of the first and second hoisting arms through a rotary mechanism, the steamer lid and the vent pipe can be moved horizontally as a whole, resulting in higher transfer efficiency and avoiding the problem of steam rushing out due to the separation of the vent pipe and the steamer lid. Furthermore, by fine-tuning the position of the second hoisting arm through a driving component, the position of the vent pipe can be fine-tuned, so that the vent pipe is placed at a specified angle, avoiding interference between the vent pipe and other structures during the transfer of the steamer lid.

[0052] The steamer lid hoisting device provided in at least one embodiment of the present invention will be described below with reference to the accompanying drawings.

[0053] like Figure 1As shown, the steamer lid hoisting device provided in this embodiment includes a fixed column 1, a rotating column 2, a first boom 3, a second boom 4, and a hoisting assembly.

[0054] In this embodiment, the fixed column 1 is a support member used to provide support for components such as the rotating column 2, the first boom 3, and the second boom 4. For example, the fixed column 1 can be as follows: Figure 1 The design shown is a rectangular column supported on the ground, and the fixed column 1 is a hollow column with an internal structure, which can be used to install hoisting components, etc.

[0055] Of course, in other embodiments, the cross-sectional shape of the fixed column 1 can also be circular, elliptical, or other regular or irregular shapes.

[0056] In some embodiments, the lower end of the fixing column 1 is further provided with an embedded part 28, for example, see [reference needed]. Figure 1 The embedded part 28 can be a steel frame structure welded from multiple steel bars. During installation, the steel frame structure is embedded in the ground building structure so that it can provide reliable support and fixation for the fixed column 1, thereby improving safety and durability.

[0057] In this embodiment, the rotating column 2 is rotatably mounted on the upper end of the fixed column 1 and is driven to rotate by a drive assembly disposed on the fixed column 1.

[0058] For details, see Figure 2 A column mounting plate is fixedly installed on the upper end of the fixed column 1. A first swivel support 7 is provided on the column mounting plate. The first swivel support 7 has an inner ring and an outer ring that can rotate relative to each other. The inner ring of the first swivel support 7 is fixedly connected to the column mounting plate, and the outer ring is rotatably located on the column mounting plate. The lower end of the swivel column 2 is fixedly connected to the outer ring of the first swivel support 7. Thus, the swivel setting of the swivel column 2 can be realized by setting the first swivel support 7 between the fixed column 1 and the swivel column 2.

[0059] See Figure 2 In this embodiment, the drive assembly includes a first motor, a first reducer, and a first gear 8. Both the first motor and the first reducer are fixed to the outside of the fixed column 1, and the output shaft of the first motor is connected to the input shaft of the first reducer. The first gear 8 is fixedly mounted on the output shaft of the first reducer. The outer ring of the first slewing support 7 has teeth on its circumferential surface, and the first gear 8 meshes with the teeth of the outer ring of the first slewing support 7. Thus, in use, the first motor outputs torque to the first reducer, which changes the direction of the torque and reduces the speed, thereby driving the first gear 8 to rotate at a low speed. The first gear 8 then transmits the torque to the outer ring of the first slewing support 7, and the rotation of the outer ring of the first slewing support 7 drives the slewing column 2 to rotate, achieving automated control of the slewing column 2 and making operation simpler and more convenient.

[0060] See Figure 2 In some embodiments, a first handwheel 21 is also provided on the first reducer. The first handwheel 21 can directly control the action of the first reducer. In this way, the first handwheel 21 can be used to manually fine-tune the rotation angle of the rotary column 2, making the control simpler and more convenient.

[0061] In this embodiment, a circumferential limiting component is also provided between the rotating column 2 and the fixed column 1. The circumferential limiting component may include a sensing bracket 9 and a first sensing element 10 and a second sensing element 11 that can sense the sensing bracket 9.

[0062] For details, see Figure 2 The sensing bracket 9 is fixedly connected to the outer side of the rotating column 2, allowing it to move circumferentially around the fixed column 1 with the rotating column 2, exhibiting an arc-shaped motion trajectory. In this embodiment, the sensing bracket 9 can... Figure 2 The design shown is an "L" shaped bracket. Of course, in other embodiments, the shape of the sensing bracket 9 can also be other.

[0063] See Figure 2 A photoelectric bracket 12 is fixedly installed on the outer side of the top of the fixed column 1. The photoelectric bracket 12 is arc-shaped and located directly below the sensing bracket 9. The first sensing element 10 and the second sensing element 11 are respectively fixed at both ends of the photoelectric bracket 12. The first sensing element 10 and the second sensing element 11 are both located directly below the arc-shaped trajectory of the sensing bracket 9 as it rotates with the rotating column 2. Thus, when the sensing bracket 9 rotates with the rotating column 2, it will pass by the first sensing element 10 and the second sensing element 11, so that the first sensing element 10 and the second sensing element 11 can sense the sensing bracket 9 and thus determine the rotation position of the rotating column 2.

[0064] In a specific example, the first sensing element 10 and the second sensing element 11 can be limit switches that are in direct contact with the sensing bracket 9, or proximity sensors that are photoelectrically sensed by the sensing bracket 9.

[0065] Based on the above-described circumferential limiting component, the rotation limit position of the rotating column 2 can be set by the sensing bracket 9, the first sensing element 10, and the second sensing element 11 during use. This rotation limit position can correspond to the position of the still and the position of the still lid. For example, when the sensing bracket 9 rotates to the first sensing element 10, it stops rotating. At this time, the first lifting arm 3 is just above the still, which is convenient for lifting or closing the still lid. When the sensing bracket 9 rotates to the second sensing element 11, it stops rotating. At this time, the first lifting arm 3 is just above the position of the still lid, which is convenient for placing the still lid. In this way, by setting two rotation limit positions, the rotation control of the rotating column 2 becomes simpler and more convenient.

[0066] See Figure 1In this embodiment, the first boom 3 and the second boom 4 are both installed on the upper part of the rotating column 2, so that they can rotate circumferentially with the rotating column 2 around the fixed column 1 as the axis, so as to realize the overall adjustment of the horizontal position of the first boom 3 and the second boom 4.

[0067] For details, see Figure 1 In this embodiment, the first boom 3 is fixedly connected to the rotating column 2, while the second boom 4 is rotatably connected to the rotating column 2 and driven to rotate by the drive member 13. This allows the horizontal position of the second boom 4 to be finely adjusted by the drive member 13, thereby finely adjusting the position of the air pipe and placing the air pipe at a specified angle to avoid interference between the air pipe and other structures during the transfer of the steamer cover.

[0068] For example, see Figure 1 and Figure 4 A support base is fixedly installed at the upper end of the slewing column 2. A second slewing bearing (not shown in the figure) is provided on the support base. The second slewing bearing has an inner ring and an outer ring that can rotate relative to each other. The outer ring of the second slewing bearing is fixed on the support base, and the inner ring is rotatably located on the support base. The end of the second boom 4 is fixedly connected to the inner ring of the second slewing bearing. In this way, by providing a second slewing bearing between the slewing column 2 and the second boom 4, the second boom 4 can be rotatably configured.

[0069] In this embodiment, the drive unit 13 includes an electric cylinder, which is hinged between the adjacent side walls of the first boom 3 and the second boom 4, for example, see... Figure 1 A first mounting base 14 is fixedly installed on the side wall of the first boom 3 near the second boom 4. The tail end of the electric cylinder is hinged to the first mounting base 14 via a pin. A second mounting base 15 is fixedly installed on the side wall of the second boom 4 near the first boom 3. The end of the electric cylinder's output rod is hinged to the second mounting base 15 via a pin. Thus, when the electric cylinder drives the output rod to extend or retract, it can drive the second boom 4 to rotate around the rotary column 2. Of course, in other embodiments, the electric cylinder can also be replaced by a drive component 13 such as an electric push rod or a pneumatic cylinder.

[0070] In this embodiment, the hoisting assembly includes a first hoisting rope 5, a second hoisting rope 6, and a rope winding structure. See also Figure 3The rope winding structure includes a first wheel 16 and a second wheel 17. A rotating shaft is rotatably mounted inside the fixed column 1. Both the first wheel 16 and the second wheel 17 are fixedly mounted on this rotating shaft. One end of the first lifting rope 5 is wound around the first wheel 16, and the other end passes through the fixed column 1, the rotating column 2, and the first boom 3 in sequence, exiting from the end of the first boom 3. One end of the second lifting rope 6 is wound around the second wheel 17, and the other end passes through the fixed column 1, the rotating column 2, and the second boom 4 in sequence, exiting from the end of the second boom 4. Thus, rotating the rotating shaft allows the first lifting rope 5 and the second lifting rope 6 to be wound and unwound via the first wheel 16 and the second wheel 17.

[0071] It should be noted that, in this embodiment, in order to facilitate the passage of the first lifting rope 5 and the second lifting rope 6, the fixed column 1, the rotating column 2, the first boom 3 and the second boom 4 are all hollow structures, and the interconnected parts are all provided with through holes for the first lifting rope 5 and the second lifting rope 6 to pass through.

[0072] See Figure 1 In some embodiments, the end of the first lifting rope 5 that passes through the first lifting arm 3 and the end of the second lifting rope 6 that passes through the second lifting arm 4 are both provided with lifting rings or hooks to facilitate the lifting of the steamer cover and the air pipe by the first lifting rope 5 and the second lifting rope 6.

[0073] Furthermore, in this embodiment, the rope winding structure also includes a drive source, which can be a handwheel connected to the rotating shaft, or a power structure connected to the rotating shaft. For example, see... Figure 1 and Figure 3 The driving source includes a second motor 18 and a second reducer 19. Both the second motor 18 and the second reducer 19 are fixedly installed on the outside of the fixed column 1. The output shaft of the second motor 18 is connected to the input shaft of the second reducer 19, and the output shaft of the second reducer 19 is connected to the rotating shaft. In this way, the first wheel 16 and the second wheel 17 can be driven to rotate automatically by the second motor 18 and the second reducer 19, so as to realize the automatic winding and unwinding of the first lifting rope 5 and the second lifting rope 6.

[0074] See Figure 1 In some embodiments, the second reducer 19 is also provided with a second handwheel 20, which can directly control the action of the second reducer 19. In this way, the lifting height of the first lifting rope 5 and the second lifting rope 6 can be manually fine-tuned using the second handwheel 20, allowing for more precise control.

[0075] See Figure 2In this embodiment, a lifting block 22 is fixedly installed on the first lifting rope 5 and the second lifting rope 6. A third sensing element 26 and a fourth sensing element 25, capable of sensing the lifting block 22, are installed inside the rotating column 2. The third sensing element 26 and the fourth sensing element 25 are located on the path along which the lifting block 22 rises and falls with the first lifting rope 5 and the second lifting rope 6, with the third sensing element 26 directly above the fourth sensing element 25. This arrangement allows for the limitation of the lifting height of the first lifting rope 5 and the second lifting rope 6 by the third sensing element 26 and the fourth sensing element 25. For example, when the lifting block 22 rises to the third sensing element 26, the rope winding structure stops unwinding. At this time, the lifting rings or hooks at the ends of the first lifting rope 5 and the second lifting rope 6 can be connected to the steamer cover and the vent pipe. When the lifting block descends to the fourth sensing element 25, the rope winding structure stops rewinding. At this time, the first lifting rope 5 and the second lifting rope 6 can lift the steamer cover and the vent pipe to the specified height. At this height, the rotation of the first boom 3 and the second boom 4 can be directly controlled. The steamer cover and the vent pipe will not interfere with other structures, which can ensure the operational stability of the lifting device.

[0076] In this embodiment, the third sensing element 26 and the fourth sensing element 25 can be limit switches that are in direct contact with the lifting block 22, or proximity sensors that are photoelectrically sensed by the lifting block 22.

[0077] See Figure 2 In this embodiment, a guide assembly is also fixedly installed inside the rotary column 2. The guide assembly includes a first guide plate 23 and a second guide plate 24. The first guide plate 23 and the second guide plate 24 are respectively fixed on opposite inner walls of the rotary column 2 and located on both sides of the lifting block 22 in the axial direction. Keyways are provided at both ends of the lifting block 22, and the keyways at both ends of the lifting block 22 are respectively inserted into the first guide plate 23 and the second guide plate 24. In this way, the cooperation between the lifting block 22 and the guide plates can guide the lifting of the hoisting rope, preventing the first hoisting rope 5 and the second hoisting rope 6 from rotating and tangling inside the fixed column 1 and the rotary column 2, ensuring smooth operation.

[0078] In this embodiment, the steamer cover hoisting device also includes a pulley system, which includes a plurality of pulleys 27 disposed inside the fixed column 1, the rotating column 2, the first boom 3 and the second boom 4.

[0079] For example, see Figure 3 Inside the fixed column 1, two pulleys 27 are installed above the first wheel 16 and the second wheel 17. The first suspension rope 5 and the second suspension rope 6 extend upwards through the two pulleys 27 into the rotating column 2.

[0080] For example, see Figure 4The top of the interior of the slewing column 2 is provided with two pulleys 27. The first lifting rope 5 and the second lifting rope 6 pass around the two pulleys 27 and extend into the first boom 3 and the second boom 4 respectively.

[0081] For example, see Figure 5 A pulley 27 is provided at the end of the first boom 3, and the first lifting rope 5 passes around the pulley 27 and passes downward from the end of the first boom 3.

[0082] For example, see Figure 6 A pulley 27 is provided at the end of the second boom 4, and the second lifting rope 6 passes around the pulley 27 and passes downward from the end of the second boom 4.

[0083] Based on the above structural design, the first lifting rope 5 and the second lifting rope 6 are pulled by multiple pulleys 27, which can save effort and change the direction of the lifting ropes, making it easier to wind up and unwind the first lifting rope 5 and the second lifting rope 6.

[0084] 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.

[0085] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. 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.
