[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, a multi-level driven parallel flexible roll-up stage is provided, including sub-stages 1, drive mechanisms 2, and joint mechanisms 3; multiple sub-stages 1 are arranged sequentially at intervals along the horizontal direction; multiple joint mechanisms 3 and multiple drive mechanisms 2 are rotatably connected between two adjacent sub-stages 1; at least one sub-stage 1 rolls upward around the corresponding joint mechanism 3 under the drive of the corresponding drive device, so that the flexible roll-up stage is in the roll-up position; each sub-stage 1 rolls downward and flattens out around the corresponding joint mechanism 3 under the drive of the corresponding drive device, so that the flexible roll-up stage is in the unfolding position.

[0025] The number of sub-stages 1, drive mechanisms 2, and joint mechanisms 3 can be specifically set according to actual needs to better meet practical requirements. Different flipping positions result in different numbers of sub-stages 1, meaning different areas, flipping angles, and heights of the flexible flipping stage. These can be set according to actual needs during use. When in the unfolded position, the flexible flipping stage can be used as a normal stage. When in the flipping position, it presents an upward-curving arc shape to meet the needs of special performances. The sub-stages 1 use sealed profiles for enhanced strength.

[0026] In this embodiment, multiple joint mechanisms 3 are sequentially spaced along the length of two adjacent sub-stages 1. The two ends of the joint mechanism 3 are rotatably connected to the rear end of the front sub-stage 1 and the front end of the rear sub-stage 1, respectively. Multiple driving devices are sequentially spaced along the length of the rear sub-stage 1. The non-driving end of the driving device is rotatably connected to the rear end of the sub-stage 1, and the driving end of the driving device is rotatably connected to the rear end of the front sub-stage 1.

[0027] In this embodiment, as Figure 3 As shown, the driving mechanism 2 includes a driving part 2.2 and a driving connecting seat 2.1. The non-driving end and the driving end of the driving part 2.2 are rotatably connected to a driving connecting seat 2.1, and the two driving connecting seats 2.1 are rotatably connected to the sub-stage 1 located in front and behind, respectively.

[0028] like Figure 4 As shown, the drive connector 2.1 includes a connector body 2.1.1, a self-lubricating bearing 2.1.2, a connecting shaft 2.1.3, and a drive fastener 2.1.4. The self-lubricating bearing 2.1.2 is mounted on the connector body 2.1.1. Both the non-drive end and the drive end of the drive part 2.2 are provided with drive connection holes. One end of the connecting shaft 2.1.3 passes through the self-lubricating bearing 2.1.2 and the corresponding drive connection hole in sequence and is then fixedly connected to the drive fastener 2.1.4. The connector body 2.1.1 is fixedly connected to the corresponding sub-stage 1.

[0029] See appendix Figure 4 Two self-lubricating bearings 2.1.2 are spaced apart on the connecting seat body 2.1.1. One end of the driving part 2.2 extends between the two self-lubricating bearings 2.1.2. One end of the connecting shaft 2.1.3 passes through the two self-lubricating bearings 2.1.2 and one end of the driving part 2.2 and is fixedly connected to the driving fastener 2.1.4.

[0030] The drive mechanism 2 adopts a multi-stage parallel drive method, which makes the force on the flexible roll-up stage more reasonable and the operation more stable.

[0031] In this embodiment, as Figure 5 As shown, the joint mechanism 3 includes a joint bearing seat 3.1, a joint shaft 3.3, a joint connecting seat 3.4, a joint bearing 3.5, and a joint fastener 3.6. The joint bearing seat 3.1 is fitted with the joint bearing 3.5. The joint connecting seat 3.4 has a joint connecting hole. One end of the joint shaft 3.3 passes through the joint connecting hole and the joint bearing 3.5 sequentially before being fixedly connected to the joint fastener 3.6. The joint bearing seat 3.1 and the joint connecting seat 3.4 are respectively fixedly connected to the corresponding sub-stage 1. A sealing cap 3.2 is provided at the end of the joint bearing 3.5. The sealing cap 3.2 is used to prevent leakage of lubricating medium and intrusion of external contaminants, ensuring the normal working condition of the joint bearing 3.5.

[0032] See appendix Figure 4 The joint connector 3.4 includes an end plate and two fixed plates perpendicularly connected to the end plate. The joint bearing 3.5 extends between the two fixed plates. The joint shaft 3.3 passes through the joint connection hole on the two fixed plates and the joint bearing 3.5 and is fixedly connected to the joint fastener 3.6.

[0033] In this embodiment, the drive mechanism 2 is driven by an underwater hydraulic cylinder, and the joint mechanism 3 is made of stainless steel, thereby ensuring that the flexible roll-up stage can be used in both normal and underwater environments.

[0034] In this embodiment, the flexible roll-up stage also includes limiting connecting blocks 4. Multiple limiting connecting blocks 4 are arranged sequentially at intervals along the length direction between two adjacent sub-stages 1 to limit the roll-up angle of the sub-stages 1.

[0035] like Figure 6 As shown, the limiting connecting block 4 includes a connecting frame 4.3, a connecting plate 4.4, a limiting shaft 4.5, and a limiting fastener 4.6. The connecting frame 4.3 is horizontally arranged and one end is fixedly connected to the front sub-stage 1. The connecting plate 4.4 is horizontally arranged and one end is fixedly connected to the rear sub-stage 1. The connecting frame 4.3 and the connecting plate 4.4 are provided with arc-shaped slots of the same shape. The connecting frame 4.3 and the connecting plate 4.4 are arranged parallel to each other. The limiting shaft 4.5 passes through the arc-shaped slots on the connecting frame 4.3 and the connecting plate 4.4 and is fixedly connected to the limiting fastener 4.6.

[0036] When the stage 1 is flipped, the connecting plate 4.4 will move relative to the connecting frame 4.3, but the moving distance will not exceed the length of the arc-shaped strip hole, thus limiting the flipping angle of the stage 1.

[0037] The limiting connecting block 4 also includes a welding plate 4.1, an adjusting pad 4.2, and an adjusting bolt. The two welding plates 4.1 are arranged in parallel and fixedly connected to the front-mounted sub-stage 1 and the connecting frame 4.3, respectively. The adjusting pad 4.2 is positioned between the two welding plates 4.1. Threaded holes are provided at corresponding positions on both the welding plates 4.1 and the adjusting pad 4.2. The adjusting bolt engages with the threaded holes on the welding plates 4.1 and the adjusting pad 4.2 to fix the welding plates 4.1 and the adjusting pad 4.2. The adjusting pad 4.2 is replaceable; different thicknesses of adjusting pads 4.2 can be selected according to actual conditions to change the connection position between the connecting frame 4.3 and the connecting plate 4.4, thereby changing the rotation angle limitation of the sub-stage 1.

[0038] In this embodiment, multiple elastic buffers are sequentially spaced along the length of two adjacent sub-stages 1. The two ends of the elastic buffers are respectively in contact with and fixed to the rear end of the front sub-stage 1 and the front end of the rear sub-stage 1. The elastic buffers can buffer the impact between the sub-stages 1 when moving from the roll-up station to the unfolding station, and can also make the movement of the sub-stages 1 from the unfolding station to the roll-up station smoother.

[0039] By adopting the above-disclosed technical solution of this invention, the following beneficial effects are obtained:

[0040] This invention provides a multi-stage, parallel-driven, flexible rolling device that can flexibly adjust the shape and state of the stage according to actual needs, achieving diverse and flexible stage presentations. When unfolded, the stage is flat and can be used as a normal stage; when rolled up, the stage is in an upward-curving state to meet special performance requirements. It is suitable for use in both normal and underwater environments.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
