DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0033] The embodiments of the present application will be described below in combination with Figures 1 to 3 .

[0034] According to the embodiment of the present application, in one aspect, a floating device is provided, which is suitable for fixing the driving device 16 on the frame 17, and the floating device comprises a first plate body 1, a guide rail 5, a connecting assembly and a rolling body 11. The first plate body 1 is suitable for being connected with the frame 17. The side wall parallel to the length direction of the guide rail 5 is connected with the first plate body 1, which can increase the connection area between the guide rail 5 and the first plate body 1 and improve the connection strength therebetween. The connecting assembly is suitable for being connected with the driving device 16, and the connecting assembly can slide along the length direction of the guide rail 5 between a first position and a second position. The rolling body 11 is connected with the connecting assembly, and the rolling body 11 is in rolling cooperation with the guide rail 5.

[0035] It can be understood that, when assembling, the guide rail 5 and the connecting assembly are assembled on the first plate body 1 first, the connecting assembly is suitable for connecting the driving device 16, and the driving device 16 is integrally arranged on the first plate body 1 through the connecting assembly, so that when being assembled with the frame 17, the first plate body 1 can be directly assembled on the frame 17, and quick installation can be realized. The rolling body 11 can be fixedly connected with the connecting assembly, and the rolling body 11 itself needs to meet the condition of being self-transmissible, so as to realize the rolling cooperation between the rolling body 11 and the guide rail 5, or the rolling body 11 can be rotatably connected with the connecting assembly, so as to realize the rolling cooperation between the rolling body 11 and the guide rail 5.

[0036] It should be noted that the floating effect is realized by the relative movement between the driving device 16 and the guide rail 5 through the rolling body 11, so that the whole can bear a larger axial force, and the occurrence of faults is reduced.

[0037] In the embodiment, the floating device is simple and practical, the driving device 16 is slidably connected with the guide rail 5 through the connecting assembly, and the rolling cooperation between the rolling body 11 and the guide rail 5 is realized, so as to realize the floating function of the driving device 16 relative to the frame 17. This design not only improves the stability and safety of the carrier in complex environment, but also effectively reduces the friction and stress concentration between the moving mechanisms, reduces the occurrence of faults, and prolongs the service life of the equipment.

[0038] In one embodiment, the guide rail 5 is provided in a pair, and the pair of guide rails 5 are parallel to each other, the connecting assembly is arranged between the pair of guide rails 5, and the connecting assembly is provided with a plurality of rolling bodies 11 along the two sides perpendicular to the length direction of the guide rail 5.

[0039] It should be noted that the pair of guide rails 5 are arranged in parallel, which can realize the rolling cooperation with the rolling body 11, and at the same time, the connecting assembly can be limited between the two guide rails 5, so as to ensure that the connecting assembly carrying the driving device 16 can stably float along the length direction of the guide rail 5.

[0040] Optionally, the guide rail 5 can be provided with one, and the rolling body 11 and the guide rail 5 are not only rollingly matched, but also the guide rail 5 and the rolling body 11 are limited, so that the guide rail 5 and the connecting assembly are prevented from being separated, thereby ensuring the stable displacement of the connecting assembly.

[0041] Optionally, the guide rail 5 can be provided with three or more, and the rolling body 11 and the guide rail 5 are rollingly matched, so that the connecting assembly is further limited, thereby ensuring the stability of the connecting assembly during displacement.

[0042] Optionally, the guide rail 5 is welded on the first plate body 1, so that the two are stably connected.

[0043] In the embodiment, a pair of parallel guide rails 5 are provided, and a plurality of rolling bodies 11 are provided on both sides of the connecting assembly, thereby further enhancing the stability and carrying capacity of the floating device. The pair of guide rails 5 make the connecting assembly slide more stably on the guide rails 5, thereby reducing the risk of failure caused by shaking or tilting.

[0044] In one embodiment, the connecting assembly includes a pair of second plate bodies 12, a connecting piece and a third plate body 7. The pair of second plate bodies 12 are parallel to each other in the length direction of the guide rail 5, and a plurality of rolling bodies 11 are rotatably connected to one side of the second plate body 12. The connecting piece is arranged between the pair of second plate bodies 12, and the pair of second plate bodies 12 are connected to the connecting piece. The third plate body 7 is connected to the first end of the pair of second plate bodies 12 in the length direction of the guide rail 5, and the third plate body 7 is adapted to be connected to the driving device 16.

[0045] It should be noted that the second plate body 12 and the third plate body 7 are welded, so that the two are stably connected. The connecting piece connects the two second plate bodies 12, so that they become a whole and complete the whole displacement action with the driving device 16. At the same time, the whole structure of the two second plate bodies 12, in combination with the arrangement of the rolling body 11, can further improve the stability during floating.

[0046] Optionally, the length direction of the second plate body 12 is consistent with the length direction of the guide rail 5, and the plurality of rolling bodies 11 are arranged on the second plate body 12 in the length direction.

[0047] Optionally, the number of the second plate body 12 corresponds to the number of the guide rail 5, and the plurality of second plate bodies 12 and the guide rail 5 are arranged one by one.

[0048] Optionally, as shown in Figure 2 The third plate body 7 is provided with a loading area for assembling the driving device 16, specifically including two through holes, and a plurality of threaded holes are arranged on the inner wall of the through hole, and the two through holes are adapted to connect the motor and the speed reducer of the driving device 16, and are connected by bolts inserted into the threaded holes.

[0049] In the embodiment, the specific structure of the connecting assembly makes the floating device more flexible and reliable. Through the rolling connection of the pair of second plate bodies 12 with the guide rails 5 and the arrangement of the connecting piece and the third plate body 7, the effective connection between the driving device 16 and the frame 17 is achieved. Not only the assembly process is simplified, but also the overall strength and durability of the floating device are improved.

[0050] In one embodiment, the fourth plate body 4, the driving piece 3 and the elastic piece 2 are further included. The fourth plate body 4 is connected with the second ends of the pair of guide rails 5 along the length direction. The driving piece 3 is connected with the fourth plate body 4. The first end of the elastic piece 2 is connected with the driving end of the driving piece 3, and the second end is connected with the third plate body 7. The elastic piece 2 acts on the third plate body 7 to make the third plate body 7 have a tendency to move from the first position to the second position.

[0051] It should be noted that the driving piece 3 can drive the elastic piece 2 to compress or stretch, thereby realizing the pressure adjustment of the driving device 16. The fourth plate body 4 is welded with the guide rail 5, thereby realizing the fixation of the relative position of the driving piece 3 and the guide rail 5, and realizing the adjustment of the compression amount of the elastic piece 2 by the driving piece 3. Since the position of the third plate body 7 is relatively fixed at the first position, when the driving piece 3 is driven, the spacing between the third plate body 7 and the driving end of the driving piece 3 can be reduced, thereby achieving the effect of compressing the elastic piece 2, and finally increasing the pressure on the driving device 16, so as to prevent the slipping from happening.

[0052] Optionally, the elastic piece 2 can be a spring.

[0053] Optionally, the driving piece 3 can be a booster cylinder, and the booster cylinder is connected with a pump station.

[0054] In the embodiment, the fourth plate body 4, the driving piece 3 and the elastic piece 2 are added in the floating device, so that the connecting assembly can automatically adjust the position within a certain range, thereby improving the adaptability and stability of the carrier under different road conditions. The arrangement of the elastic piece 2 can also play a buffering role, reducing the damage to the driving device 16 and the frame 17 caused by impact or vibration. At the same time, the driving piece 3 can boost the elastic piece 2, thereby increasing the positive pressure of the driving wheel in the driving device 16, and the phenomenon of slipping can be avoided.

[0055] In one embodiment, the connecting piece includes a cylinder body 10 and a pair of first connecting plates 8. The cylinder body 10 is sleeved outside the elastic piece 2. The pair of first connecting plates 8 are respectively arranged on both sides of the cylinder body 10 and are respectively connected with the pair of second plate bodies 12.

[0056] It should be noted that the cylinder 10 as the core component connecting the two second plate bodies 12 is sleeved outside the elastic member 2, which can play a reinforcing effect while reducing the space occupation. At the same time, it can also guide the elastic member 2 to ensure that the elastic member 2 can be directional compression or release, avoiding bending away from the axial direction.

[0057] In this embodiment, the specific structure design of the connecting piece enables the elastic member 2 to stably act on the third plate body 7 while maintaining the overall strength and stability of the connecting assembly. The arrangement of the cylinder 10 and the first connecting plate 8 not only simplifies the assembly process, but also improves the reliability and service life of the floating device.

[0058] In one embodiment, it also includes a limiting bolt 15 connected with the first plate body 1. In the first position, the third plate body 7 abuts against the limiting bolt 15. In the second position, the third plate body 7 is separated from the limiting bolt 15.

[0059] It should be noted that the first plate body 1 is provided with a threaded hole, and the limiting bolt 15 is assembled with the threaded hole, which can limit the third plate body 7 below. The fourth plate body 4 arranged above can limit the second plate body 12. The two cooperate to limit the connecting assembly along the length direction of the guide rail 5, avoiding the rolling body 11 from falling off the guide rail 5.

[0060] In this embodiment, by arranging the limiting bolt 15, the sliding range of the connecting assembly on the guide rail 5 is limited, thereby avoiding failure or damage caused by excessive sliding. This design not only improves the safety of the floating device, but also ensures the stability and accuracy of the trolley during driving. The fourth plate body 4 arranged can play the effect of upper limiting.

[0061] In one embodiment, the guide rail 5 is provided with a through slot, the length direction of the through slot is consistent with the length direction of the guide rail 5, and the rolling body 11 is at least partially arranged in the through slot and rolls with the inner side wall of the through slot.

[0062] Optionally, the guide rail 5 can be arranged as a C channel steel, and the C channel arranged is the through slot.

[0063] Optionally, the rolling body 11 can be arranged as a roller.

[0064] In this embodiment, the guide rail 5 is provided with a through slot, so that the rolling body 11 can be partially or entirely arranged in the through slot and roll with the inner side wall of the through slot, improving the stability and durability of the rolling body 11.

[0065] In one embodiment, it also includes a second connecting plate 14, the first end of which is connected with the first plate body 1, and the second end is connected with the guide rail 5.

[0066] It should be noted that the second connecting plate 14 serves as a reinforcing structure, which can enhance the connection strength between the guide rail 5 and the first plate body 1.

[0067] Optionally, the second connecting plate 14, the guide rail 5 and the first plate body 1 are welded with each other.

[0068] Optionally, the second connecting plate 14 can be provided as a triangular plate, and two adjacent sides of the second connecting plate 14 are connected with the guide rail 5 and the first plate body 1 respectively.

[0070] In one embodiment, the mounting bolt 13 is further provided on the first plate body 1, and the first plate body 1 is adapted to be connected with the vehicle frame 17 through the mounting bolt 13.

[0071] In the embodiment, the mounting bolt 13 is provided to facilitate the installation and disassembly of the floating device, improving the maintainability and flexibility of the trolley.
