Description

Technical Field

[0001] This application relates to the field of lifting device technology, and in particular to a steamer lid lifting device. Background Technology

[0002] As is well known, baijiu is a typical representative of traditional Chinese distilled spirits. Its brewing process integrates microbiology, biochemistry, fermentation engineering, and traditional techniques, forming a unique flavor system and cultural connotation. Furthermore, the baijiu brewing process is extremely complex, consisting of multiple steps, each requiring different equipment. Among these, the still-steaming process, as the core of distillation, directly affects the yield and quality of the spirit. The lifting of the still lid during this process is a crucial operation.

[0003] Traditionally, fixed-point fulcrums or temporary supports are used to lift the still lid. However, these methods have several problems: 1) Fixed-point fulcrums cannot freely adjust the fulcrum position, resulting in insufficient process adaptability. Different cycles require different frequencies of use, and repeated use over a long period can lead to safety hazards for operators; 2) Fixed-point fulcrums have ergonomic design flaws. During long-term operation, operators must frequently adopt abnormal postures, which not only exacerbates operator fatigue but also easily leads to process deviations such as still lid tilting and steam leakage, potentially causing steam leakage around the still and resulting in base liquor loss; 3) Temporary supports pose operational safety hazards. Insufficient structural rigidity of temporary components may lead to load imbalance, and non-standardized operation processes can disrupt the original balance, causing the fulcrum to swing unexpectedly under dynamic loads, leading to the risk of collision.

[0004] Therefore, there is an urgent need for a device to solve the technical problems mentioned above. Utility Model Content

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0044] The structures, proportions, sizes, etc., shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this application. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0045] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "lateral," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the purpose of simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In related technologies, fixed-point fulcrum booms or temporary supports are used to lift the still lid. However, these methods have several problems: 1) Fixed-point fulcrum booms cannot freely adjust the fulcrum position, resulting in insufficient process adaptability. Different cycles require different boom usage frequencies, and repeated use over a long period can lead to safety hazards for operators; 2) Fixed-point fulcrum booms have ergonomic design flaws. With a fixed boom height, operators must frequently adopt abnormal postures during long-term operation. This forced posture adjustment not only exacerbates operator fatigue but also easily leads to process deviations such as still lid tilting and steam leakage, potentially causing steam leakage around the still and resulting in base liquor loss; 3) Temporary supports pose operational safety hazards. Insufficient structural rigidity of temporary components can lead to load imbalance, and non-standardized operation processes can disrupt the original balance, causing the boom to swing unexpectedly under dynamic loads, leading to a risk of collision. Therefore, this application provides a steamer lid lifting device, which is achieved through the cooperation of positioning mechanism 2, lifting mechanism 2 and fulcrum mechanism 3. It can realize the positioning of the steamer lid lifting device and the height adjustment of fulcrum mechanism 3, making it more flexible and versatile in different rounds of use and avoiding the occurrence of safety hazards. At the same time, it can be adapted to operators of different heights, reducing a series of problems caused by height. It can also avoid the risk of collision and achieve the effect of improving operational safety.

[0047] The following is a detailed description of a steamer lid lifting device provided in this embodiment, with reference to the accompanying drawings. Figures 1-2 As shown, it includes: a positioning mechanism 1, which is used to position the still lid lifting device; the positioning mechanism 1 is equipped with a lifting mechanism 2 and a fulcrum mechanism 3; the lifting mechanism 2 is used to lift the still lid at the top of the still; the fulcrum mechanism 3 is used to provide fulcrum support for the lifting mechanism 2, including an adjustment component 31 disposed on the lifting mechanism 2, and a fixing component 32 and a fulcrum component 33 disposed on the adjustment component 31; the adjustment component 31 is used to adjust the position of the fulcrum mechanism 3; the fixing component 32 is used to fix the position of the adjustment component 31; the fulcrum component 33 is used to provide fulcrum support for the lifting mechanism 2.

[0048] Specifically, the positioning mechanism 1 positions the entire still lid lifting device. The positioning mechanism 1 includes a lifting mechanism 2 and a fulcrum mechanism 3. Since the still lid and the still are interlocked, the lifting mechanism 2 can lift the still lid upwards when they are not interlocked. The fulcrum mechanism 3 includes an adjusting component 31 on the lifting mechanism 2, a fixing component 32 on the adjusting component 31, and a fulcrum component 33. The adjusting component 31 can adjust the position of the fulcrum mechanism 3 according to the operator's height, facilitating the operator to press down on the lifting mechanism 2. The fixing component 32 can fix the position of the adjusting component 31 after it has been adjusted to a suitable position. The fulcrum component 33 provides a suitable fulcrum support for the lifting mechanism 2 when the operator presses down on it.

[0049] The above operation, through the setting of positioning mechanism 1, can effectively solve the problem of safety hazards caused by the use of temporary supports in related technologies; it can prevent the occurrence of load imbalance, unexpected swinging, and collision risks; the coordinated setting of lifting mechanism 2 and fulcrum mechanism 3 can effectively solve the problem of poor human-machine compatibility and large operational safety hazards caused by the use of fixed fulcrums in related technologies, thereby enhancing the comfort of operators and improving the stability, operational efficiency, and operational safety of the steaming process.

[0050] Preferred, refer to Figure 1 , Figure 3 As shown, the adjustment component 31 includes a first adjustment piece 311 and a second adjustment piece 312 that are hinged together; the first adjustment piece 311 and the second adjustment piece 312 form an openable clamping structure to be sleeved on the positioning mechanism 1 and move up and down along the height direction of the positioning mechanism 1.

[0051] Specifically, the adjustment component 31 includes a first adjustment piece 311 and a second adjustment piece 312. The first adjustment piece 311 and the second adjustment piece 312 are hinged together by a three-section hinge 313. The first adjustment piece 311 and the second adjustment piece 312 form an openable clamping structure to be fitted onto the positioning mechanism 1, and can move up and down along the height direction of the positioning mechanism 1 to realize the position adjustment of the fulcrum mechanism 3.

[0052] It should be noted that the unfolded length of the three-section hinge 313 can be set to 80mm so that the opening angle of the first adjusting plate 311 and the second adjusting plate 312 is appropriate, and the positioning mechanism 1 can be quickly clamped or released. This can ensure sufficient clamping force while avoiding the problem of structural loosening caused by excessively long hinge 313, thereby further ensuring the stability and reliability during lifting.

[0053] In one feasible approach, refer to Figure 1 , Figure 3 As shown, the first adjusting plate 311 and the second adjusting plate 312 are both arranged in a semi-circular shape, and the diameter of the first adjusting plate 311 and the second adjusting plate 312 is set to 68mm.

[0054] Specifically, the first adjusting plate 311 and the second adjusting plate 312 are both arranged in a semi-circular shape, and the diameter of the first adjusting plate 311 and the second adjusting plate 312 can both be set to 68mm. Therefore, when the first adjusting plate 311 and the second adjusting plate 312 are connected, they can form a circle with a diameter of 68mm to match the positioning mechanism 1. They can then be fitted onto the positioning mechanism 1 to achieve the effect of large contact area, strong friction, and difficulty in slipping during hoisting after the first adjusting plate 311 and the second adjusting plate 312 are connected and clamped.

[0055] The above operation, by setting the adjustment component 31, can precisely control the position of the fulcrum so as to adapt to the height of the operator, thereby improving the operator's comfort and enhancing the safety of operation.

[0056] Preferred, refer to Figure 1 , Figure 3 As shown, the fixing component 32 includes a first fixing plate 321 disposed on the first adjusting plate 311, a second fixing plate 322 disposed on the second adjusting plate 312, a fastening bolt 323 disposed between the first fixing plate 321 and the second fixing plate 322, and a fastening nut 324 disposed on the fastening bolt 323; both the first fixing plate 321 and the second fixing plate 322 are provided with threaded holes, and the fastening nut 324 is threadedly connected to the end of the fastening bolt 323 after passing through the threaded hole, so as to fix the adjusting component 31.

[0057] Specifically, the fixing assembly 32 includes a first fixing plate 321, a second fixing plate 322, fastening bolts 323, and fastening nuts 324. The first fixing plate 321 and the first adjusting piece 311 are fixedly connected by full welding, and the second fixing plate 322 and the second adjusting piece 312 are fixedly connected by full welding; when the first adjusting piece 311 and the second adjusting piece 312 are aligned, the first fixing plate 321 and the second fixing plate 322 are in contact with each other. Both the first fixing plate 321 and the second fixing plate 322 have threaded holes, and the fastening bolts 323 are sequentially inserted into the threaded holes of the first fixing plate 321 and the second fixing plate 322, and the fastening nuts 324 are threadedly connected to the end of the fastening bolts 323 after they pass through the threaded holes, thereby achieving the fixing of the adjusting assembly 31.

[0058] In one feasible approach, refer to Figure 1 , Figure 3As shown, the length of the first fixing plate 321 and the width of the second fixing plate 322 are both set to 80mm and 40mm respectively; the diameter of the fastening bolt 323 is set to 18mm and the length is set to 60mm.

[0059] Specifically, both the first fixing plate 321 and the second fixing plate 322 are steel plates, and their lengths can be set to 80mm and their widths can be set to 40mm; the diameter of the fastening bolt 323 can be set to 18mm and its length can be set to 60mm.

[0060] Here, the combination of 80mm and 60mm allows the fastening bolt 323 to be adjusted up to 60mm, thus meeting the fulcrum height requirements of operators of different heights (1.6-1.9m). The 40mm setting enhances the bending resistance of the fulcrum structure and ensures smooth adjustment. The combination of 18mm and 60mm further enhances the strength of the fastening bolt 323, stably supporting the weight of the still lid and avoiding the risk of breakage. The 60mm length is suitable for one-handed operation, with the fulcrum height changing by approximately 2mm per rotation, achieving quick and precise adjustment. Simultaneously, the threaded hole length can be set to 20mm and the width to 12mm, making the movement direction of the fastening bolt 323 controllable and preventing misalignment and jamming.

[0061] The above operation, through the coordinated arrangement of the first fixing plate 321, the second fixing plate 322, the fastening bolt 323 and the fastening nut 324, can achieve the limiting and fixing of the adjusting component 31, thus achieving the effect of simple structure, easy operation and quick installation.

[0062] Preferred, refer to Figure 1 , Figure 3 As shown, the fulcrum assembly 33 includes a connecting vertical rod 331 disposed on the first adjusting plate, a supporting horizontal rod 332 disposed on the connecting vertical rod 331, and a supporting vertical rod 333 disposed on the supporting horizontal rod 332. The connecting vertical rod 331, the supporting horizontal rod 332, and the supporting vertical rod 333 form an S-shaped arrangement to achieve fulcrum support for the lifting mechanism 2.

[0063] Specifically, the fulcrum assembly 33 includes a connecting vertical rod 331, a supporting horizontal rod 332, and a supporting vertical rod 333. The connecting vertical rod 331 and the first adjusting plate 311 are fixedly connected by full welding, with a full welding length of 80mm, to ensure the connection strength between them. This, in turn, ensures the connection strength of the fixing assembly 32, the adjusting assembly 31, and the fulcrum assembly 33, achieving a long-term crack-resistant effect. Here, the connecting vertical rod 331, the supporting horizontal rod 332, and the supporting vertical rod 333 can be fixedly connected by full welding or integrally formed. The connecting vertical rod 331, the supporting horizontal rod 332, and the supporting vertical rod 333 can form an S-shaped arrangement with a length of 380mm and a diameter of 15mm, which, while providing fulcrum support for the lifting mechanism 2, also disperses the stress, avoids local stress concentration, and extends the service life.

[0064] The above operation, the setting of the fulcrum component 33, can provide fulcrum support for the lifting mechanism 2 when the operator presses down on it, so as to reduce the force on the operator and save the operator time and effort.

[0066] Specifically, the positioning mechanism 1 includes a positioning rod 11 and a positioning assembly 12. The positioning rod 11 is vertically arranged, and its lower end is fixed to the ground.

[0067] The positioning assembly 12 includes a positioning frame 121 and a connecting rotating part 122. The positioning frame 121 includes a vertical support rod 1211, a horizontal support rod 1212 fixedly connected to the upper end of the vertical support rod 1211, and an inclined rod 1213 fixedly connected to the horizontal support rod 1211 and the vertical support rod 1212 at both ends, respectively. The vertical support rod 1211, the horizontal support rod 1212, and the inclined rod 1213 form a triangular arrangement to enhance the stability of the overall positioning mechanism 1. Furthermore, the openable clamping structure formed by the first adjusting plate and the second adjusting plate is sleeved on the vertical support rod 1211, thereby allowing it to move along the length direction of the vertical support rod 1211 to adjust the fulcrum position of the fulcrum mechanism 3.

[0068] In one feasible approach, refer to Figure 1As shown, the connecting rotating part 122 includes an upper connecting block 1221 and a lower connecting block 1222; the upper connecting block 1221 is used to realize the rotational connection between the positioning rod 11 and the upper end of the positioning frame 121; the lower connecting block 1222 is used to realize the rotational connection between the positioning rod 11 and the lower end of the positioning frame 121; and the lower connecting block 1222 is provided with a limit rod 1231; the limit rod 1231 is used to limit the lifting mechanism 2 after the lifting mechanism 2 has completed the downward pressing.

[0069] Specifically, the connecting rotating part 122 includes an upper connecting block 1221 and a lower connecting block 1222. One end of the upper connecting block 1221 has an upper rotating hole. The upper connecting block 1221 is sleeved on the upper end of the positioning rod 11 at the position of the upper rotating hole and is rotatably connected to the positioning rod 11. The lower surface of the other end of the upper connecting block 1221 is fixedly connected to the upper end of the vertical connecting rod 121, thereby realizing the relative rotatable connection between the positioning rod 11 and the upper end of the positioning frame 121.

[0070] One end of the lower connecting block 1222 has a lower rotating hole, and the lower connecting block 1222 is sleeved on the lower end of the positioning rod 11 at the position of the lower rotating hole and is rotatably connected to the positioning rod 11. The other end of the lower connecting block 1222 has a fixing hole, and the lower connecting block 1222 is sleeved on the lower end of the vertical support rod 1211 at the position of the fixing hole and is fixedly connected to the vertical support rod 1211. This allows for a relative rotatable connection between the positioning rod 11 and the lower end of the positioning frame 121.

[0071] Here, the lower connecting block 1222 is fixedly connected to the side of the vertical support rod 1211 with a limit rod 12111. The limit rod 12111 is set in a figure-7 shape, so that the lifting mechanism 2 can be limited after the lifting mechanism 2 has finished pressing down.

[0072] The above operation, through the setting of positioning mechanism 1, can prevent the occurrence of load imbalance, unexpected swaying and collision risks; the relative rotation of positioning rod 11 and positioning frame 121 can facilitate the adjustment of the position of positioning frame 121, so as to facilitate the lifting operation of the steamer cover located in different positions.

[0074] In one possible implementation, the connecting part 21 includes a support frame 211 disposed on the positioning frame 121, a connecting rod 212 disposed on the support frame 211, and a connecting frame 213 disposed on the connecting rod 212; the connecting frame 213 and the lifting rod 22 are rotatably connected for downward pressing by the operator; the lifting assembly 23 includes a lifting frame 231 disposed on the lifting rod 22 and a lifting part 232 disposed on the lifting frame 231; the lifting frame 231 is used to connect the lifting rod 22 and the lifting part 232; the lifting part 232 is used to pull the steamer cover up and lift it, and the lower end of the lifting part 232 is provided with a steamer hook 23221; the steamer hook 23221 is used to hook the steamer cover and lift the steamer cover.

[0075] Specifically, the connecting part 21 includes a support frame 211, a connecting rod 212, and a connecting frame 213.

The rotating shaft 4 passes through the lifting rod 22, and the lifting rod 22 is rotatably connected to the connecting frame 213 at the position of the rotating shaft 4.

[0076] The lifting assembly 23 includes a lifting frame 231 and a lifting part 232; the end of the lifting rod 22 away from the operator passes through the lifting frame 231 and is fixedly connected to the lifting frame 231. The lower end of the lifting frame 231 is fixedly connected to the upper pull rod 5. The lower end of the upper pull rod 5 is provided with three sets of lifting parts 232. Each set of lifting parts 232 includes three lifting rings 2321 and two lifting connecting rods 2322. Two lifting rings 2321 are respectively sleeved with another lifting ring 2321 and are fixedly connected to the upper ends of the two lifting connecting rods 2322 respectively.

[0077] The above operation, by setting up lifting mechanism 2, can realize the lifting operation of the steamer lid, and the overall lifting structure has strong stability and is convenient to operate.

[0078] The implementation principle of this embodiment is as follows: In use, firstly, according to the position of the still lid, the positioning frame 121 rotates relative to the positioning rod 11 so that the lifting part 232 is located directly above the still lid. At the same time, the still hook 23221 hooks the still ring on the still lid to facilitate later lifting. Next, according to the height of the operator, the positions of the first adjusting plate 311 and the second adjusting plate 312 are adjusted. After the adjustment is completed, the positions of the first adjusting plate 311 and the second adjusting plate 312 are fixed by fastening bolts 323 and fastening nuts 324. Then, the lower end face of the lifting rod 22 is attached to the position of the fulcrum assembly 33 to support the fulcrum of the lifting rod 22. Finally, the operator presses down on the lifting rod 22, and the lifting rod 22 rotates relative to the connecting frame 213. At the same time, the lifting rod 22 drives the lifting frame 231 to lift upward, and the lifting frame 231 drives the lifting part 232 to pull upward, thereby realizing the lifting operation of the still lid.
