[0029] Please refer to Figures 1-4 , the present utility model provides a lifting device for a steaming tank, which includes at least two lifting components 3. The two lifting components 3 are respectively arranged at opposite ends of the steaming tank along the length direction of the steaming tank; the lifting component 3 includes a bracket 30, a rotating shaft 31, a driving unit 32, and at least two towing ropes 33. The bracket 30 is arranged on the tank body 1 of the steaming tank, the rotating shaft 31 is rotatably arranged on the bracket 30, the rotating shaft 31 is horizontally arranged, the extending direction of the rotating shaft 31 is perpendicular to the length direction of the steaming tank, and the rotating shaft 31 is located above the steaming tank; the driving unit 32 is arranged on the bracket 30, the driving unit 32 is a driving motor, the driving unit 32 is drivingly connected to the rotating shaft 31 for driving the rotating shaft 31 to rotate; the towing ropes 33 extend in the vertical direction, the first ends of at least two towing ropes 33 are respectively connected to opposite ends of the rotating shaft 31, and the second ends of at least two towing ropes 33 are respectively connected to opposite sides of the steaming tank cover 2.

[0030] In the present utility model, two sets of lifting components 3 are respectively arranged at opposite ends of the steaming tank along the length direction of the steaming tank. At least two traction ropes 33 of each set of lifting components 3 are respectively connected to opposite sides in the width direction of the steaming tank cover 2. Driven synchronously by the driving units 32 of the two sets of lifting components 3, the rotating shafts 31 of the two sets of lifting components 3 rotate synchronously, so that the traction ropes 33 of the two sets of lifting components 3 drive the steaming tank cover 2 to rise or fall synchronously. That is, the present utility model uses the four-corner balance to stably drive the steaming tank cover 2 to rise or fall, with high precision, stability and reliability. At the same time, the use of a transmission chain drive is avoided, effectively solving the problem that the transmission chain of the existing lifting device for the steaming tank needs to use lubricating oil for a long time, resulting in inconvenient use of the lifting device for the steaming tank.

[0031] In addition, the lifting component 3 further includes at least two wire wheels 310. Each wire wheel 310 corresponds to each traction rope 33 one by one. The wire wheel 310 is sleeved on the rotating shaft 31, and the traction rope 33 is wound around the wire wheel 310. Compared with the traction rope 33 directly wound on the rotating shaft 31, since the outer diameter of the wire wheel 310 is larger than the outer diameter of the rotating shaft 31, when the wire wheel 310 rotates one circle around the rotating shaft 31, the traction rope 33 can drive the steaming tank cover 2 to rise a large distance, playing a role in magnifying the rising distance of the steaming tank cover 2.

[0032] In this embodiment, the traction rope 33 is selected as a steel wire rope, which can improve the safety of using the steaming tank cover 2. The traction rope 33 of this embodiment is connected to the steaming tank cover 2 through a rope locking device 4, so as to facilitate the connection between the traction rope 33 and the steaming tank cover 2.

[0033] In one embodiment, the bracket 30 includes a connecting plate 302 and two support plates 301. The two support plates 301 are respectively arranged on opposite sides in the width direction of the tank body 1, and the support plates 301 can be fixed to the tank body 1 by bolts; wherein, the support plates 301 extend in the vertical direction, the connecting plate 302 is arranged above the steaming tank cover 2, the connecting plate 302 connects the two support plates 301, and the rotating shaft 31 is rotatably arranged on the connecting plate 302 through a pedestal bearing 5. It can be seen that the installation of the rotating shaft 31 can be facilitated through such a bracket 30 structure. In order to improve the stability of the up and down movement of the steaming tank cover 2, a guiding structure is arranged between the support plate 301 and the steaming tank, and the steaming tank cover 2 is guided to rise or fall through the guiding structure.

[0034] In one embodiment, an upper travel switch (not shown) and a lower travel switch (not shown) are also fixedly arranged on the support plate 301 at intervals in the vertical direction. The upper travel switch is used to control the ascending travel of the steaming tank cover 2, and the lower travel switch is used to control the descending travel of the steaming tank cover 2. Specifically, both the upper travel switch and the lower travel switch are electrically connected to the driving unit 32. When the steaming tank cover 2 rises to a preset ascending position under the drive of the driving unit 32, the upper travel switch feeds back the detected result to the driving unit 32, and at this time, the driving unit 32 stops driving; when the steaming tank cover 2 descends to a preset descending position under the drive of the driving unit 32, the lower travel switch feeds back the detected result to the driving unit 32, and at this time, the driving unit 32 stops driving.

[0035] In one embodiment, the guiding structure includes a guiding groove 34 and a guiding slider 35. A guiding groove 34 extending in the vertical direction is arranged on the side wall of the support plate 301 facing the steaming tank, and the guiding slider 35 is fixed on the steaming tank cover 2 and is slidably connected with the guiding groove 34. Specifically, it can be understood that the driving unit 32 drives the rotating shaft 31 to rotate, drives the wire wheel 310 to rotate, thereby driving the traction rope 33 to drive the steaming tank cover 2 to move along the guiding groove 34, and further improving the stability of the movement of the steaming tank cover 2.

[0036] In other embodiments, the guiding structure may also include a guiding slider 35 and a guiding rod. The guiding rod extends in the vertical direction, and the guiding slider 35 is slidably connected with the guiding rod along the extending direction of the guiding rod. In this way, the steaming tank cover 2 can also move up and down stably along the guiding groove 34. Therefore, for those skilled in the art, by reasonably changing the guiding structure, it should also fall within the protection scope of the present invention.

[0037] On the basis of the above structure, the lifting component 3 further includes a limiting mechanism, which is used to limit the downward movement of the steaming tank cover 2. In this way, after the steaming tank cover 2 moves to a preset height, the steaming tank cover 2 can be supported by the limiting mechanism, which can reduce the pulling force of the traction rope 33 on the steaming tank cover 2, avoid the falling of the steaming tank cover 2 caused by the breakage of the traction rope 33, and improve the safety of using the steaming tank cover 2. Specifically, the limiting mechanism includes a telescopic mechanism 36 and a fixed seat. The telescopic mechanism 36 and the fixed seat are arranged on each support plate 301. The fixed seat is arranged opposite to the telescopic rod 360. The telescopic rod 360 of the telescopic mechanism 36 extends and retracts in the horizontal direction, and the extending and retracting direction of the telescopic rod 360 is the same as the length direction of the steaming tank. The telescopic rod 360 of the telescopic mechanism 36 can slide through the fixed seat and limit the downward movement of the guiding slider 35. That is to say, it can be understood that when the steaming tank cover 2 is driven by the driving unit 32 and rises to a preset position, the telescopic rod 360 of the telescopic mechanism 36 starts to extend and slide through the fixed seat. The fixed seat can enhance the supporting performance of the telescopic rod 360 on the guiding slider 35. The guiding slider 35 of the steaming tank cover 2 can be supported by the telescopic rod 360, and the downward movement of the guiding slider 35 can be limited, so as to avoid the risk of the steaming tank cover 2 falling caused by the breakage of the traction rope 33; when the steaming tank cover 2 needs to be lowered to seal with the tank body 1, the telescopic rod 360 of the telescopic mechanism 36 retracts to avoid interfering with the downward movement of the steaming tank cover 2.

[0038] In this embodiment, there are two telescopic mechanisms 36. The two telescopic mechanisms 36 are respectively arranged on the two support plates 301. The telescopic rods 360 of the two telescopic mechanisms 36 are respectively used to limit the downward movement of the guiding sliders 35 on the relatively two sides in the width direction of the steaming tank cover 2, further improving the safety of using the steaming tank cover 2.

[0039] In one embodiment, the telescopic mechanism 36 of this embodiment is configured as a cylinder; in other embodiments, the telescopic mechanism 36 can also be configured as an electric push rod or a hydraulic push rod.

[0040] In one embodiment, a receiving groove 3101 is formed on the outer peripheral wall surface of the wire wheel 310. The receiving groove 3101 is arranged along the circumferential direction of the wire wheel 310. The traction rope 33 is wound in the receiving groove 3101, improving the convenience of connecting the traction rope 33 with the wire wheel 310.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
