[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] like Figures 1-10 As shown, the present invention provides a floating body conveying device, comprising at least two conveying units 100, which are used to convey a floating body unit 200. The two ends of the floating body unit 200 are respectively located on the two conveying units 100. The floating body unit 200 includes two cylindrical floating bodies arranged in parallel and two rectangular floating bodies located at both ends of the cylindrical floating body. The floating body conveying unit 100 conveys the rectangular floating body, so the floating body conveying device needs to be configured to include at least two conveying units 100. In the case of conveying multiple columns of floating body units 200 at the same time, two adjacent columns of floating bodies can share one conveying unit 100, for details, see Figure 1-Figure 2 As shown, this embodiment takes the case of simultaneously transporting two floating bodies as an example. Accordingly, three transport units 100 are provided to simultaneously transport two rows of floating body units 200. In other embodiments, more rows of floating body units 200 can also be transported simultaneously, and the number of transport units 100 can be increased accordingly. The details will not be repeated here. The transport unit 100 includes a bracket 1, a plurality of transport rollers 2, and a drive assembly 3. Please refer to Figure 3-Figure 7 As shown, the bracket 1 includes a frame structure consisting of two longitudinal beams 11 and two transverse beams 12 and a plurality of legs 13. The two longitudinal beams 11 are arranged in parallel along the conveying direction of the floating unit 200. The two ends of the transverse beam 12 are fixedly connected to the two longitudinal beams 11 respectively. The two transverse beams 12 are arranged at intervals along the length direction of the longitudinal beams 11. The plurality of legs 13 are fixedly connected to the two longitudinal beams 11 respectively and are used to support the bracket 1. By setting the length of each leg 13, it is ensured that the upper surface of the bracket 1 remains horizontal. The plurality of conveying rollers 2 are arranged at intervals along the length direction of the longitudinal beams 11. The two ends of the conveying rollers 2 are connected to the two longitudinal beams 11 respectively. The conveying rollers 2 are used to support and convey the floating unit 200. The transverse beam 12 is located below the longitudinal beam 11, so as to avoid the transverse beam 12 occupying the installation space of the conveying roller 2. The driving assembly 3 includes a driving member 31 and a push plate 33. The driving member 31 is installed on the bracket 1, specifically, it is installed on one of the longitudinal beams 11. As shown Figures 1-4 As shown, in the case where two floating units 200 need to be carried and transported, two driving members 31 are provided, and the two driving members 31 are respectively installed on the two longitudinal beams 11. Figure 1 , and combined with Figure 9-10As shown, the output end of the driving member 31 is connected to a push plate 33. The driving member 31 can drive the push plate 33 to be pushed out or retracted along the conveying direction of the floating unit 200. The push plate 33 is used to propel the floating unit 200 forward. When the driving member 31 drives the push plate 33 to be pushed out, the push plate 33 abuts against the output end of the driving member 31 and propels the cylindrical floating body in front of the floating unit 200 forward. When the driving member 31 drives the push plate 33 to be retracted, the push plate 33 and the floating unit 200 can rotate relative to the driving member 31. When the push plate 33 contacts the cylindrical floating body behind the floating unit 200, the push plate 33 rotates to avoid the floating unit 200. When the driving member 31 drives the push plate 33 to be pushed out again, the push plate 33 contacts the cylindrical floating body behind the floating unit 200 and continues to propel it forward. That is, during the entire conveying process, the driving member 31 drives the push plate 33 to push out, then retract and push out again, and the corresponding floating unit 200 is conveyed through two pushes of the push plate 33. For floating units 200 with other structures, such as those with three cylindrical floats, the push plate 33 can be pushed out three times in this embodiment to complete the conveying of the floating unit 200. The specific movement process is not detailed here.

[0039] The floating conveying device in this embodiment utilizes a driver 31 to drive a push plate 33 to propel the floating unit 200 forward. The power for conveying the floating unit 200 is no longer provided by the conveying roller 2, so even slippage will not affect the conveying process. Furthermore, the push plate 33 can rotate relative to the driver 31 during retraction, thereby avoiding the floating unit 200 during retraction, achieving one-way conveyance of the floating unit 200. The power transmission path is directly from the driver 31 to the push plate 33, resulting in a shorter path, better adapting to the conveying environment of the floating unit 200 and meeting the user's needs.

[0040] Further, if Figure 4 、 Figure 9 and Figure 10As shown, the drive assembly 3 also includes a fixed plate 32, which is fixedly connected to the output end of the drive member 31. A push plate 33 is hingedly connected to the side of the fixed plate 32 facing away from the drive member 31, and the push plate 33 partially overlaps with the fixed plate 32. When the drive member 31 drives the push plate 33 forward, the push plate 33 contacts the cylindrical float located in front of the floating unit 200. Since the fixed plate 32 partially overlaps with it, the push plate 33 can push the floating unit 200 forward without rotating, and always remains in contact with the fixed plate 32 during this process. In addition, an elastic member 34 is provided between the push plate 33 and the fixed plate 32. The two ends of the elastic member 34 are respectively connected to the push plate 33 and the fixed plate 32. The elastic member 34 is used to keep the push plate 33 in contact with the fixed plate 32. That is, when the push plate 33 is not in contact with the floating unit 200, it always remains in contact with the fixed plate 32 under the action of the elastic member 34. Specifically, when the driving member 31 drives the push plate 33 to retract, the push plate 33 contacts the cylindrical floating body behind the floating unit 200. As the driving member 31 further moves, the push plate 33 overcomes the elastic force of the elastic member 34 and rotates in a direction away from the fixed plate 32, thereby avoiding the floating unit 200 during the retraction process. When the push plate 33 is retracted to the rear of the cylindrical floating body behind the floating unit 200, the push plate 33 disengages from it and, under the elastic force of the elastic member 34, returns to its original position and re-engages the fixed plate 32. The driving member 31 then drives the push plate 33 out again, pushing the cylindrical floating body behind the floating unit 200 to continue forward, ultimately completing the transportation of the floating unit 200.

[0041] Optionally, the elastic member 34 in this embodiment is configured as a coil spring or a torsion spring. When the elastic member 34 is configured as a coil spring, one end of the coil spring is connected to the side of the fixed plate 32 facing the drive member 31, and the other end is connected to the push plate 33, thereby ensuring that the push plate 33 can be pressed against the fixed plate 32 under the elastic force of the coil spring. When the elastic member 34 is configured as a torsion spring, the torsion spring is mounted on the hinge axis between the fixed plate 32 and the push plate 33, with one torsion arm of the torsion spring resting on the side of the fixed plate 32 facing away from the drive member 31, and the other torsion arm resting on the side of the push plate 33 facing away from the fixed plate 32. This similarly ensures that the push plate 33 is pressed against the fixed plate 32 under the elastic force of the torsion spring. Simultaneously, the coil spring or torsion spring is configured with a relatively low elastic coefficient, thereby reducing the elastic force acting on the push plate 33, ensuring that the push plate 33 can rotate normally to avoid retraction during retraction, thereby preventing the floating unit 200 from being pulled back. In this embodiment, the elastic member 34 is preferably a coil spring, and two coil springs are provided. The two coil springs are respectively located on both sides of the fixing plate 32 to ensure a smooth reset action of the push plate 33 .

[0042] For details, please refer to Figure 10As shown, both the push plate 33 and the fixed plate 32 are connected to hinges 35. The hinge 35 on the fixed plate 32 is connected to the side of the fixed plate 32 facing away from the driving member 31, and the hinge 35 on the push plate 33 is connected to the lower end of the push plate 33. The hinge 35 on the fixed plate 32 is rotatably connected to the hinge 35 on the push plate 33. The hinge 35 is configured as a sleeve structure and is connected to the fixed plate 32 or the push plate 33 by welding, and the rotational connection is achieved via a rotating shaft.

[0043] Alternatively, see Figure 9 As shown, because the hinge 35 is configured as a sleeve structure, a gap inevitably exists between the push plate 33 and the fixed plate 32. After the push plate 33 abuts the fixed plate 32, it tilts backward, resulting in a force component tangential to the floating unit 200 when pushing the floating unit 200. Therefore, a limiter 36 is threadedly connected to the fixed plate 32. The limiter 36 is disposed between the fixed plate 32 and the push plate 33 and above the hinge 35. The push plate 33 can abut against the end of the limiter 36. By adjusting the depth of the limiter 36 screwed into the fixed plate 32, the push plate 33 can remain upright after abutting, and the entire thrust during the pushing process can only act on the floating unit 200.

[0044] Optionally, the driving member 31 in this embodiment is a reciprocating linear motion driving member 31, for example, it can be in the form of an integral device, such as an electric push rod. It can also be in the form of a combined device, such as a motor-threaded screw structure, or a motor-crank slider structure. In this embodiment, the driving member 31 is preferably an electric push rod to reduce the structural complexity of the device.

[0045] Furthermore, if Figure 8 As shown, the conveying roller 2 includes a roller 21 and bearing seats 22 located at both ends of the roller 21. Figure 4-Figure 7 As shown, two bearing blocks 22 are fixedly connected to the longitudinal beam 11, and the roller 21 is rotatably connected to the bearing blocks 22 via bearings. The bracket 1 also includes a shield 15, which is fixedly connected to the longitudinal beam 11 and positioned above the bearing blocks 22. Shield 15 has multiple mounting holes 151 spaced along its length. The roller 21 is rotatably connected to the bearing blocks 22 through one of these mounting holes 151. The shield 15 prevents mud and sand from splashing into the bearing blocks 22, which could cause wear or damage to the bearings.

[0046] Specifically, the roller 21 is provided with a V-shaped section 212 and two straight sections 211. The two straight sections 211 are located at both ends of the V-shaped section 212. The V-shaped section 212 can guide the floating unit 200, thereby ensuring that the conveying direction is parallel to the longitudinal beam 11 during the conveying process of the floating unit 200. The V-shaped section 212 has an hourglass-shaped structure, and its two large ends are respectively connected to the two straight sections 211. The straight sections 211 are used to support the floating unit 200. When the floating unit 200 is conveyed forward, the two rectangular floats at its two ends are respectively on the rollers 21 of the two conveying units 100. The V-shaped sections 212 of the rollers 21 of the two conveying units 100 have a component force on the floating unit 200 along the length direction of the rollers 21, and the forces are in opposite directions. When the force components acting on the floating unit 200 do not reach a force balance, the floating unit 200 deflects or twists along the length direction of the roller 21 until the force components reach a force balance, thereby straightening the floating unit 200.

[0047] Alternatively, as Figure 4-Figure 7 As shown, the support 1 further includes two guard plates 14, one at each end of the support 1. The ends of the guard plates 14 are fixedly connected to the two longitudinal beams 11. The plurality of conveyor rollers 2 are arranged parallel to the guard plates 14 and located between the two guard plates 14. The guard plates 14 protect the conveyor rollers 2, preventing damage to the conveyor rollers 2 caused by direct impact from the front or rear end of the support 1.

[0048] It should be noted that when transporting the floating unit 200, the floating transport device can be configured as a multi-row structure according to site requirements, with multiple transport units 100 arranged in each row. Multiple rows of transport units 100 are connected end to end, thereby achieving long-distance transport of the floating unit 200. During the transport process, the two drive assemblies 3 corresponding to the same floating unit 200 operate synchronously to ensure smooth forward transport of the floating unit 200.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
