[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0029] like Figures 1-6As shown, this utility model provides a handling device for a smoke machine, including a base plate 1, a turntable 2, a steering wheel assembly, and a traveling wheel assembly. The base plate 1 is provided with a first mounting seat 11, a second mounting seat 12, and a third mounting seat 13, with the first mounting seat 11 located between the second mounting seat 12 and the third mounting seat 13. A support shaft 21 is provided on the turntable 2, which is rotatably connected to the first mounting seat 11, and its axis is vertical. The turntable 2 is located above and parallel to the base plate 1. The turntable 2 is used to bear heavy objects and rotates relative to the base plate 1 via the support shaft 21. The turntable 2 is spaced apart from the base plate 1 to avoid friction between the turntable 2 and the base plate 1 during rotation. The steering wheel assembly and the traveling wheel assembly are respectively installed at the front and rear ends of the base plate 1. The steering wheel assembly is used for both travel and steering, while the traveling wheel assembly is only used for travel, thus ensuring stable travel and accurate steering. Specifically, the steering wheel assembly includes a steering wheel 3 and a bogie 4. The steering wheel 3 is rotatably connected to the bogie 4, and the bogie 4 is rotatably connected to the second mounting base 12. The rotation axes of the bogie 4 and the second mounting base 12 are also in the vertical direction. The traveling wheel assembly is rotatably connected to the third mounting base 13. Due to the large size and weight of the tobacco hood equipment, multiple tobacco hood equipment handling devices can be used in concert during handling. The multiple support positions of the tobacco hood equipment are placed one-to-one on the turntables 2 of the multiple tobacco hood equipment handling devices. Thus, during the handling process, when one or more tobacco hood equipment handling devices turn, their turntables 2 rotate relative to the base plate 1, ensuring the stability of the tobacco hood equipment and preventing slippage during handling.
[0030] Furthermore, such as Figures 3-6 As shown, the first mounting base 11 extends downward toward the base plate 1. The first mounting base 11 has a first mounting hole 111, the axis of which is set vertically. The support shaft 21 is rotatably connected to the first mounting hole 111 through the first bearing assembly 22. By setting the first mounting base 11 to extend downward toward the base plate 1, the rotational table 2 is supported while the space occupied above the base plate 1 is reduced, thereby reducing the height of the rotational table 2, lowering the center of gravity during transportation, and making the posture more stable during transportation.
[0031] Specifically, please refer to Figure 4 and Figure 6As shown, the first bearing assembly 22 includes tapered roller bearings and deep groove ball bearings. A first limiting protrusion 112 protrudes from the wall of the first mounting hole 111. The tapered roller bearing and the deep groove ball bearing are respectively disposed on both sides of the first limiting protrusion 112, with the tapered roller bearing located on the side closer to the rotary table 2. By using a combination of tapered roller bearings and deep groove ball bearings, reliable axial support can be provided to the rotary table 2, preventing axial displacement of the rotary table 2 due to large loads during handling. In other embodiments, the first bearing assembly 22 can also be configured as a combination of two angular contact bearings, with the orientation of the two angular contact bearings set according to the actual scenario.
[0032] Please refer to Figure 4 As shown, the first limiting protrusion 112 is used to limit the tapered roller bearing and the deep groove ball bearing. A stepped structure is provided at the end of the support shaft 21 near the rotary table 2 to stop the tapered roller bearing. A first locking member 23 is connected to the end of the support shaft 21 away from the rotary table 2. The first locking member 23 is used to prevent the deep groove ball bearing from dislodging from the first mounting hole 111, thereby achieving reliable support for the tapered roller bearing and the deep groove ball bearing. The first locking member 23 can be a retaining ring or a locking nut. In this embodiment, the first locking member 23 is preferably a locking nut, which is threaded to the support shaft 21. A bearing retaining ring is also provided between the locking nut and the deep groove ball bearing, thereby stopping the deep groove ball bearing.
[0033] Alternatively, please refer to Figure 4 As shown, a thrust bearing 24 is also provided between the base plate 1 of the rotary table 2. The thrust bearing 24 is used to provide axial support for the rotary table 2 to increase the axial structural strength of the rotary table 2.
[0034] Furthermore, please refer to Figures 1-6As shown, the second mounting base 12 extends upward toward the base plate 1. The second mounting base 12 has a second mounting hole 121, the axis of which is vertically oriented. A steering shaft 41 is mounted on the bogie 4, and the steering shaft 41 is rotatably connected to the second mounting hole 121 via a second bearing assembly 42. The axle of the steering wheel 3 is rotatably connected to the bogie 4, and the axis of the second mounting hole 121 is perpendicular to the axis of the steering wheel 3. By setting the second mounting base 12 to extend upward toward the base plate 1, the space requirement below the base plate 1 is reduced without affecting the space above it, while still providing support for the bogie 4. This lowers the height of the base plate 1, thereby lowering the center of gravity during transport and making the posture more stable. When turning is required, the base plate 1 rotates, causing the traveling wheel assembly to change its direction of travel. The base plate 1 rotates relative to the rotating shaft, and the direction of travel of the steering wheel 3 is at a certain angle to the direction of travel of the traveling wheel assembly; this angle is the angle at which the base plate 1 rotates. After the base plate 1 stops rotating, the steering wheel 3, under the reverse force of the ground, drives the bogie 4 to rotate in the opposite direction, causing the steering shaft 41 to rotate in the opposite direction relative to the base plate 1, until the direction of travel of the steering wheel 3 is consistent with the direction of travel of the traveling wheel assembly, thus completing the steering. When the orientation of the transported tobacco hood needs to be changed, it is only necessary to move one or more of the tobacco hood's transport devices to the corresponding position. During this process, the turntable 2 of each transport device involved in transporting the tobacco hood rotates to different degrees relative to the base plate 1, completing the orientation change of the transported tobacco hood while preventing the transported tobacco hood from sliding on the transport device.
[0035] Specifically, please refer to Figure 4 and Figure 6 As shown, the second bearing assembly 42 includes tapered roller bearings and deep groove ball bearings. A second limiting protrusion 122 protrudes from the wall of the second mounting hole 121. The tapered roller bearing and the deep groove ball bearing are respectively disposed on both sides of the second limiting protrusion 122, with the tapered roller bearing located on the side closer to the bogie 4. By using a combination of tapered roller bearings and deep groove ball bearings, reliable axial support can be provided to the bogie 4, preventing tilting of the base plate 1 caused by axial displacement of the bogie 4 due to large loads during handling. In other embodiments, the second bearing assembly 42 can also be configured as a combination of two angular contact bearings, with the orientation of the two angular contact bearings set according to the actual scenario.
[0036] Please refer to Figure 4As shown, the second limiting protrusion 122 is used to limit the tapered roller bearing and the deep groove ball bearing. A stepped structure is provided at the end of the steering shaft 41 near the bogie 4 to stop the tapered roller bearing. A second locking member 43 is connected to the end of the steering shaft 41 away from the turntable 2. The second locking member 43 is used to prevent the deep groove ball bearing from disengaging from the second mounting hole 121, thereby achieving reliable support for the tapered roller bearing and the deep groove ball bearing. The second locking member 43 can be a retaining ring or a locking nut. In this embodiment, the second locking member 43 is preferably a locking nut, which is threaded to the steering shaft 41. A bearing retaining ring is also provided between the locking nut and the deep groove ball bearing, thereby stopping the deep groove ball bearing.
[0037] Alternatively, please refer to Figure 3 As shown, the steering wheel 3 is a shuttle-shaped wheel, which facilitates the steering of the conveying device of the tobacco machine and reduces the resistance during the steering process.
[0038] Optionally, the traveling wheel assembly includes multiple traveling wheels 5, and multiple third mounting seats 13 are provided on the base plate 1. The multiple traveling wheels 5 correspond one-to-one with the multiple third mounting seats 13, and the axles of the traveling wheels 5 are rotatably connected to the third mounting seats 13. By setting multiple traveling wheels 5, the load borne by the conveying device of the smoke machine is borne by the steering wheels 3 and the multiple traveling wheels 5, reducing the load borne by a single traveling wheel 5.
[0039] Alternatively, please refer to Figure 1 and combined Figure 6 As shown, the base plate 1 is also provided with a fourth mounting seat 14. The fourth mounting seat 14 is located on the side of the second mounting seat 12 away from the first mounting seat 11 and extends outward from the edge of the base plate 1. A handle 6 is rotatably connected to the fourth mounting seat 14, which enables the pushing and pulling of the conveying device of the range hood and the turning of the conveying device. The fourth mounting seat 14 facilitates the operator's pushing, pulling, and turning operations of the conveying device of the range hood, and avoids occupying too much space on the base plate 1, thus reducing the volume occupied by the conveying device of the range hood.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
