Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically, to a novel structure for hoisting a wine still. Background Technology

[0002] Currently, in the liquor brewing industry, the swing arm rotation mechanism of the old-style still plays a crucial role in the production process. However, its structural design has obvious defects. Existing swing arm rotation mechanisms mostly use tapered bearings or copper bushings as core components. During long-term operation, due to the need to continuously withstand large eccentric forces, the contact parts of the tapered bearings or copper bushings wear at an extremely fast rate. When the wear reaches a certain level, the tapered bearings or copper bushings are prone to deformation, which seriously affects the normal operation of the bearings, and in turn causes the still arm to jam or even seize up.

[0003] To address the aforementioned issues, existing technologies typically employ the method of periodically replacing tapered bearings or copper bushings to maintain equipment operation. However, this approach requires significant manpower for disassembly, installation, and other maintenance tasks. The maintenance process is complex, demands high technical skills from maintenance personnel, and is difficult to maintain, resulting in lengthy maintenance times. Furthermore, the frequent replacement of parts significantly increases material costs, severely impacting the company's economic benefits. More seriously, if equipment malfunctions and cannot be repaired promptly, it could lead to the shutdown of the entire liquor brewing production line, causing substantial economic losses to the company. In addition, the large number of worn parts removed are difficult to recycle, resulting in resource waste and environmental pressure. Moreover, existing technologies fail to fundamentally solve the wear problem caused by eccentric forces, thus failing to achieve a substantial improvement in the performance of the still arm's rotating mechanism. Utility Model Content

[0004] The present invention aims to provide a novel hoisting structure for wine stills to solve the problems in the prior art, such as rapid wear and deformation of core components, easy jamming and jamming, need for regular replacement of core components, large amount of maintenance work, high difficulty, long operation time, and potential production stoppage in severe cases.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model embodiment provides a novel still hoisting structure, which includes a still arm;

[0007] The top end of the aforementioned steamer arm is provided with an L-shaped rotating arm, and the short side end of the aforementioned L-shaped rotating arm is rotatably connected to the top end of the aforementioned steamer arm.

[0008] The short side of the L-shaped rotary arm is provided with a support hole, and a force-bearing support is installed in the support hole. The force-bearing support, the steamer arm and the short side of the L-shaped rotary arm are coaxial with each other.

[0009] The aforementioned load-bearing support column is provided with a lifting eye tie rod, an open-body tie rod, and a lifting eye bolt at the angle between the long side of the aforementioned L-shaped rotating arm;

[0010] The end of the aforementioned eyelet rod closest to the aforementioned support column is hinged to the top of the aforementioned support column, the end of the aforementioned eyelet rod furthest from the aforementioned support column is movably connected to one end of the aforementioned open-body rod, the other end of the aforementioned open-body rod is threaded to the aforementioned eyelet bolt, and the end of the aforementioned eyelet bolt furthest from the aforementioned open-body rod is fixedly connected to the long side of the aforementioned L-shaped swivel arm.

[0011] In use, first, push the L-shaped rotating arm on the steamer arm to rotate it so that the L-shaped rotating arm is above the steamer cover. Then, hang the hanging rope on the steamer cover on the bottom surface of the L-shaped rotating arm. By rotating the open-body pull rod, the lifting ring bolt can be tightened or loosened, thereby adjusting the tension between the L-shaped rotating arm and the load-bearing support, and thus balancing the gravity generated by the L-shaped rotating arm and the steamer cover. Finally, by pushing or pulling the L-shaped rotating arm to rotate, the steamer cover can be moved.

[0012] The novel still-lifting structure disclosed in this embodiment features a load-bearing support column at the top of the still arm. Between the load-bearing support column and the L-shaped rotating arm, a lifting ring rod, an open-body rod, and a lifting ring bolt are installed. By rotating the open-body rod, the lifting ring bolt can be tightened or loosened, thereby adjusting the tension between the L-shaped rotating arm and the load-bearing support column. This facilitates the offsetting of most of the eccentric force borne by the tapered bearing, reducing wear on the tapered bearing and extending its service life. Consequently, this novel still-lifting structure offers the following advantages: core components are less prone to wear and deformation, less prone to jamming, low maintenance costs, minimal maintenance workload, short operation time, high production efficiency, long service life, effective prevention of L-shaped rotating arm falls, improved safety, and convenient maintenance.

[0013] Optionally: A first lifting ring is fixedly installed on the top surface of the long side of the L-shaped swing arm. The first lifting ring is installed away from the load-bearing support. A second lifting ring is provided at the end of the lifting ring bolt away from the open tie rod. The second lifting ring on the lifting ring bolt is interlocked with the first lifting ring on the L-shaped swing arm.

[0014] With this configuration, the second lifting ring is interlocked with the first lifting ring, allowing the end of the lifting ring bolt away from the open-body tie rod to be connected to the top surface of the long side of the L-shaped rotating arm, facilitating the lifting of the long side of the L-shaped rotating arm.

[0015] Optionally: the end of the aforementioned eye bolt away from the aforementioned second eye has a threaded rod, and the end of the aforementioned open-body tie rod near the aforementioned threaded rod has a connecting nut, and the aforementioned threaded rod is threaded onto the aforementioned connecting nut.

[0016] With this configuration, the lifting eye bolt can be tightened or loosened by rotating the open-body tie rod, thereby adjusting the tension between the L-shaped rotating arm and the load-bearing support, balancing the gravity generated by the L-shaped rotating arm and the steamer cover, and offsetting most of the eccentric force borne by the connection between the steamer arm and the L-shaped rotating arm, thus preventing damage to the connection between the steamer arm and the L-shaped rotating arm.

[0017] Optionally: the end of the open-body tie rod away from the eye bolt has a through hole, the end of the eye bolt near the open-body tie rod rotatably passes through the through hole, and the end of the eye bolt inside the open-body tie rod has an enlarged end that abuts against the end of the through hole near the eye bolt.

[0018] This configuration allows the open-body tie rod to rotate relative to the lifting ring tie rod, facilitating the rotation of the open-body tie rod and enabling the tightening or loosening of the lifting ring bolt. This facilitates the adjustment of the tension between the L-shaped rotating arm and the load-bearing support.

[0019] Optionally: A double bearing seat is installed at the top of the above-mentioned load-bearing support, and a rotating shaft is provided at the top of the double bearing seat. The end of the rotating shaft near the double bearing seat is fixedly connected to the inner ring of the double bearing inside the double bearing seat, and the end of the lifting ring rod near the load-bearing support is hinged to the top of the rotating shaft.

[0020] With this configuration, when the L-shaped rotating arm rotates, the support column remains stationary. The double bearing seat allows the rotating shaft to rotate freely relative to the double bearing seat. At the same time, the hinged connection between the lifting ring rod and the rotating shaft increases the flexibility of the connection between the lifting ring rod and the rotating shaft, significantly reducing the possibility of jamming during the rotation of the L-shaped rotating arm. This results in less resistance to the L-shaped rotating arm during rotation, making the rotation smoother and less strenuous, and effectively improving the working performance of the still arm.

[0021] Optionally: A connecting groove is provided on the outer wall of the rotating shaft, the depth of the connecting groove is less than the diameter of the rotating shaft, and the length of the connecting groove is greater than the diameter of the rotating shaft;

[0022] Bolt holes are symmetrically provided on both sides of the connecting groove. A bolt rod is provided in the bolt hole. The bolt rod passes through the bolt hole and the connecting groove and is threaded with a self-locking nut. The end of the lifting ring rod near the load-bearing support is hinged to the bolt rod in the connecting groove.

[0023] This design facilitates the hinged connection, and allows workers to remove the lifting ring rod by removing the bolt rod on the rotating shaft, thus easily disassembling other components for convenient maintenance or replacement.

[0024] Optionally, a tapered bearing is installed at the top of the aforementioned steamer arm, and the bottom of the short side of the aforementioned L-shaped rotating arm is rotatably connected to the aforementioned tapered bearing.

[0025] With this configuration, the tapered bearing can easily rotate the L-shaped swing arm. By properly adjusting the tightness of the lifting ring rod, the open-body rod, and the lifting ring bolt, force balance can be achieved. This not only improves the service life of the tapered bearing but also reduces the eccentric force and gravity acting on it.

[0026] Optionally, the bottom end of the aforementioned support column passes through the aforementioned support hole and the inner ring of the aforementioned tapered bearing in sequence and is fixedly connected to the inside of the aforementioned steamer arm. The diameter of the aforementioned support column is smaller than the inner ring diameter of the aforementioned tapered bearing.

[0027] With this configuration, the supporting pillar and the inner ring of the tapered bearing do not come into contact with each other, which greatly reduces the jamming phenomenon of the L-shaped rotating arm during rotation. This makes the L-shaped rotating arm experience less resistance during rotation, resulting in smoother and more effortless rotation, and effectively improving the working performance of the still arm.

[0028] Optionally, the bottom surface of the front end of the L-shaped swing arm is equipped with a lifting device for lifting the still, and the still lid is attached to the lifting device.

[0029] With this configuration, the lifting device is more flexible, making it easy to adjust the angle for lifting the still lid. The still lid is conveniently and quickly hooked onto the lifting device, effectively improving the working performance of the still lifting structure and increasing production efficiency.

[0030] Optionally, the bottom end of the steamer arm is provided with a base, the base is welded to the bottom end of the steamer arm, and the cross-sectional area of ​​the base is larger than the cross-sectional area of ​​the steamer arm.

[0031] With this configuration, the base is designed to allow the still arm to be fixed to the ground or workstation, ensuring that the still hoisting structure has sufficient load-bearing points and is easy to use.

[0032] In summary, the novel wine steamer hoisting structure disclosed in this utility model has the following advantages: core components are not easily worn or deformed, not easily jammed or stuck, maintenance costs are low, maintenance workload is small, operation time is short, production efficiency is high, service life is long, it effectively prevents the L-shaped swing arm from falling, and improves safety and ease of maintenance.

The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example

[0039] See Figure 1 This embodiment proposes a novel still hoisting structure, including a still arm 1;

[0040] The top end of the steamer arm 1 is provided with an L-shaped rotating arm 2, and the short side end of the L-shaped rotating arm 2 is rotatably connected to the top end of the steamer arm 1.

[0041] The short side of the L-shaped rotary arm 2 is provided with a support hole 3, and a force-bearing support 4 is installed in the support hole 3. The force-bearing support 4, the steamer arm 1 and the short side of the L-shaped rotary arm 2 are coaxial with each other.

[0042] The angle between the load-bearing support column 4 and the long side of the L-shaped swing arm 2 is provided with a lifting ring rod 5, an open-body rod 6 and a lifting ring bolt 7;

[0043] The end of the eye ring rod 5 closest to the support column 4 is hinged to the top of the support column 4, and the end of the eye ring rod 5 furthest from the support column 4 is movably connected to one end of the open-body rod 6. The other end of the open-body rod 6 is threaded to the eye ring bolt 7, and the end of the eye ring bolt 7 furthest from the open-body rod 6 is fixedly connected to the long side of the L-shaped rotating arm 2.

[0044] In use, first, push the L-shaped rotating arm 2 on the steamer arm 1 to rotate it so that the L-shaped rotating arm 2 is above the steamer cover 20. Then, hang the hanging rope on the steamer cover 20 on the bottom surface of the L-shaped rotating arm 2. By rotating the open-body pull rod 6, the lifting ring bolt 7 can be tightened or loosened, thereby adjusting the tension between the L-shaped rotating arm 2 and the load-bearing support 4, and thus balancing the gravity generated by the L-shaped rotating arm 2 and the steamer cover 20. Finally, by pushing or pulling the L-shaped rotating arm 2 to rotate, the steamer cover 20 can be moved.

[0045] The novel still hoisting structure disclosed in this embodiment features a support column 4 at the top of the still arm 1, and a lifting ring rod 5, an open-body rod 6, and a lifting ring bolt 7 between the support column 4 and the L-shaped rotating arm 2. By rotating the open-body rod 6, the lifting ring bolt 7 can be tightened or loosened, thereby adjusting the tension between the L-shaped rotating arm 2 and the support column 4. This facilitates the offsetting of most of the eccentric force borne by the tapered bearing 18, reduces the wear of the tapered bearing 18, and extends its service life. Consequently, this novel still hoisting structure offers the following advantages: core components are not easily worn or deformed; jamming is less likely; maintenance costs are low; maintenance workload is small; operation time is short; production efficiency is high; service life is long; the L-shaped rotating arm 2 is effectively prevented from falling; and safety and maintenance are improved.

[0046] Optionally: A first lifting ring 8 is fixedly installed on the top surface of the long side of the L-shaped swing arm 2. The first lifting ring 8 is installed away from the load-bearing support 4. The end of the lifting ring bolt 7 away from the external tie rod 6 has a second lifting ring 9. The second lifting ring 9 on the lifting ring bolt 7 is interlocked with the first lifting ring 8 on the L-shaped swing arm 2.

[0047] With this configuration, the second lifting ring 9 is interlocked with the first lifting ring 8, allowing the end of the lifting ring bolt 7 that is far from the body tie rod 6 to be connected to the top surface of the long side of the L-shaped rotating arm 2, making it easier to lift the long side of the L-shaped rotating arm 2.

[0048] Optionally: the end of the eye bolt 7 away from the second eye 9 has a screw 10, and the end of the open-body tie rod 6 near the screw 10 has a connecting nut 11, with the screw 10 threaded onto the connecting nut 11.

[0049] With this configuration, the lifting eye bolt 7 can be tightened or loosened by rotating the open-body pull rod 6, thereby adjusting the tension between the L-shaped rotating arm 2 and the load-bearing support 4, thus balancing the gravity generated by the L-shaped rotating arm 2 and the steamer cover 20, offsetting most of the eccentric force borne at the connection between the steamer arm 1 and the L-shaped rotating arm 2, and preventing damage to the connection between the steamer arm 1 and the L-shaped rotating arm 2.

[0050] Optionally: the open-body tie rod 6 has a through hole 12 at the end away from the eye bolt 7, the eye bolt 5 has a rotatable through hole 12 at the end near the open-body tie rod 6, and the end of the eye bolt 5 on the inner side of the open-body tie rod 6 has an enlarged end (not shown in the figure), which abuts against the end of the through hole 12 near the eye bolt 7.

[0051] This configuration allows the open-body tie rod 6 to rotate relative to the lifting eye bolt 5, facilitating the rotation of the open-body tie rod 6 and enabling the tightening or loosening of the lifting eye bolt 7. This facilitates the adjustment of the tension between the L-shaped rotating arm 2 and the load-bearing support 4.

[0052] Optionally: A double bearing seat 13 is installed at the top of the support column 4, and a rotating shaft 14 is provided at the top of the double bearing seat 13. The end of the rotating shaft 14 near the double bearing seat 13 is fixedly connected to the inner ring of the double bearing inside the double bearing seat 13, and the end of the lifting ring rod 5 near the support column 4 is hinged to the top of the rotating shaft 14.

[0053] With this configuration, when the L-shaped rotating arm 2 rotates, the force-bearing support 4 remains stationary. The double bearing seat 13 allows the rotating shaft 14 to rotate freely relative to the double bearing seat 13. At the same time, the hinged connection between the lifting ring rod 5 and the rotating shaft 14 improves the flexibility of the connection between the lifting ring rod 5 and the rotating shaft 14, greatly reducing the phenomenon of jamming during the rotation of the L-shaped rotating arm 2. This results in less resistance to the L-shaped rotating arm 2 during rotation, making the rotation smoother and more labor-saving, and effectively improving the working performance of the still arm 1.

[0054] Optionally: A connecting groove 15 is provided on the outer wall of the rotating shaft 14, the depth of the connecting groove 15 is less than the diameter of the rotating shaft 14, and the length of the connecting groove 15 is greater than the diameter of the rotating shaft 14;

[0055] Bolt holes 16 are symmetrically provided on both sides of the connecting groove 15. Bolt rods 17 are provided in the bolt holes 16. The bolt rods 17 pass through the bolt holes 16 and the connecting groove 15 and are threaded with self-locking nuts (not shown in the figure). The end of the lifting ring rod 5 near the force-bearing support 4 is hinged to the bolt rods 17 in the connecting groove 15.

[0056] This design facilitates the hinged connection, and allows workers to remove the lifting ring rod 5 by removing the bolt rod 17 on the rotating shaft 14, thereby easily disassembling other components for convenient maintenance or replacement.

[0057] Optionally, a tapered bearing 18 is mounted on the top of the steamer arm 1, and the bottom of the short side of the L-shaped rotating arm 2 is rotatably connected to the tapered bearing 18.

[0058] With this configuration, the tapered bearing 18 can easily rotate the L-shaped swivel arm 2. By properly adjusting the tightness of the lifting ring rod 5, the open-body rod 6, and the lifting ring bolt 7, a force balance can be achieved. This not only improves the service life of the tapered bearing 18, but also reduces the eccentric force and gravity acting on the tapered bearing 18.

[0059] Optionally, the bottom end of the support column 4 passes through the support hole 3 and the inner ring of the tapered bearing 18 in sequence and is fixedly connected to the inside of the steamer arm 1. The diameter of the support column 4 is smaller than the inner ring diameter of the tapered bearing 18.

[0060] With this configuration, the support column 4 and the inner ring of the tapered bearing 18 do not come into contact with each other, which greatly reduces the jamming phenomenon of the L-shaped rotating arm 2 during rotation. This makes the L-shaped rotating arm 2 experience less resistance during rotation, and the rotation is smoother and less strenuous, effectively improving the working performance of the still arm 1.

[0061] Optionally, the bottom surface of the front end of the L-shaped swing arm 2 is equipped with a lifting device 19 for lifting the still, and the still cover 20 is attached to the lifting device 19.

[0062] With this configuration, the lifting device 19 is more flexible and easy to adjust the angle to lift the still lid 20. The still lid 20 is conveniently and quickly hooked onto the lifting device 19, which effectively improves the working performance of the still lifting structure and increases production efficiency.

[0063] Optionally, a base 21 is provided at the bottom end of the steamer arm 1. The base 21 is welded to the bottom end of the steamer arm 1, and the cross-sectional area of ​​the base 21 is larger than the cross-sectional area of ​​the steamer arm 1.

[0064] With this configuration, the base 21 is designed to allow the still arm 1 to be fixed on the ground or workstation, ensuring that the still hoisting structure has sufficient load-bearing points and is easy to use.

[0065] In this embodiment, the novel still hoisting structure can significantly extend the service life of the tapered bearing 18, reduce equipment maintenance time, save manpower and material costs, and ensure stable equipment operation. At the same time, the structure is simple in design and can be applied to hoisting different types of still lids 20.

[0066] The specific connection principle of the novel still hoisting structure in this embodiment:

[0067] By opening a support hole 3 on the short side of the L-shaped rotating arm 2, the load-bearing support 4 passes through the support hole 3 and the inner ring of the tapered bearing 18 and is securely installed and fixed inside the steamer arm 1. The diameter of the load-bearing support 4 is smaller than the inner ring diameter of the tapered bearing 18, and the two do not contact each other. A double bearing seat 13 is installed at the top of the load-bearing support 4. There is a bearing at the top and bottom of the double bearing seat 13. The rotating shaft 14 passes through the inner rings of the two bearings inside the double bearing seat 13, so that the rotating shaft 14 can rotate freely relative to the double bearing seat 13. It should be noted that the center of the load-bearing support 4, the center of the tapered bearing 18, and the center of the double bearings in the double bearing seat 13 are on the same straight line. A connecting groove 15 is opened on the rotating shaft 14. The depth of the connecting groove 15 is slightly less than the diameter of the rotating shaft 14, and the length of the connecting groove 15 is greater than 1.5 times the diameter of the rotating shaft 14. A bolt hole 16 is drilled, and a bolt rod 17 passes through the bolt hole 16. The bolt rod 17 passes through the connecting groove 15 in the middle, and the other end of the bolt rod 17 is locked with a self-locking nut. The lifting ring of the lifting ring rod 5 is passed through the bolt rod 17 in the connecting groove 15. The other end of the lifting ring rod 5 is movably connected to the open-body rod 6, so that the open-body rod 6 can rotate relative to the lifting ring rod 5. The other end of the open-body rod 6 is threadedly connected to the lifting ring bolt 7. The second lifting ring 9 of the lifting ring bolt 7 is engaged with the first lifting ring 8 on the rotating arm. By rotating the open-body rod 6, the lifting ring bolt 7 can be tightened or loosened, thereby adjusting the tension between the L-shaped rotating arm 2 and the load-bearing support 4, thereby balancing the gravity generated by the L-shaped rotating arm 2 and the steamer cover 20, offsetting most of the eccentric force borne by the tapered bearing 18, reducing the wear of the tapered bearing 18, and extending its working life.

[0068] In this embodiment, the structure can reasonably adjust the tension of the pull rod to achieve force balance according to the actual use. This not only improves the service life of the tapered bearing 18, but also reduces the eccentric force and gravity on the tapered bearing 18, greatly reducing the jamming phenomenon of the L-shaped rotating arm 2 during rotation. This makes the L-shaped rotating arm 2 experience less resistance during rotation, making the rotation smoother and more labor-saving, and effectively improving the working performance of the wine steamer hoisting structure.

[0069] In this embodiment, the L-shaped swing arm 2 may fall due to welding process problems or aging of connectors. In this case, the support column 4 can prevent the L-shaped swing arm 2 from falling, which is equivalent to a protective mechanism to ensure the safety of employees.

[0070] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
