[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present 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 only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, a flexible rolling stage with multi-stage drive in parallel is provided, including a sub-stage 1, a driving mechanism 2 and a joint mechanism 3; a plurality of sub-stages 1 are arranged in sequence and spaced apart in the horizontal direction; a plurality of joint mechanisms 3 and a plurality of driving mechanisms 2 are rotatably connected between two adjacent sub-stages 1 in the front and rear directions; at least one sub-stage 1 is rolled upward around the corresponding joint mechanism 3 under the drive of the corresponding driving device, so that the flexible rolling stage is in the rolling position; each of the sub-stages 1 is rolled downward and flattened around the corresponding joint mechanism 3 under the drive of the corresponding driving device in turn, so that the flexible rolling 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 actual requirements. Different flipping stations enable different numbers of sub-stages 1 to be rolled up, that is, the area of ​​the flexible rolling stage is different, and the rolling angle and height are different. In actual use, they can be set according to actual needs. When the flexible rolling stage is in the unfolding position, it can be used as a normal stage. When the flexible rolling stage is in the rolling position, it presents an upward arc shape to meet the needs of special performances. The sub-stage 1 uses a sealed profile to make it more stress-resistant.

[0026] In this embodiment, a plurality of joint mechanisms 3 are sequentially arranged at intervals along the length direction between two adjacent front and rear sub-stages 1, and the two ends of the joint mechanisms 3 are rotatably connected to the rear end of the sub-stage 1 located in the front and the front end of the sub-stage 1 located in the rear, respectively; a plurality of driving devices are sequentially installed at intervals along the length direction in the sub-stage 1 located in the rear, and 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 sub-stage 1 located in the front.

[0027] In this embodiment, 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 respectively rotatably connected to a driving connecting seat 2.1, and the two driving connecting seats 2.1 are respectively rotatably connected to the sub-stages 1 located in the front and the rear.

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

[0029] See attached 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 into between the two self-lubricating bearings 2.1.2, and 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 driving mechanism 2 adopts a multi-stage parallel driving method, which makes the force of the flexible rolling stage more reasonable and the operation more stable.

[0031] In this embodiment, Figure 5 As shown, the joint mechanism 3 includes a joint bearing seat 3.1, a joint shaft 3.3, a joint connection seat 3.4, a joint bearing 3.5, and a joint fastener 3.6. The joint bearing seat 3.1 is mounted with the joint bearing 3.5, and the joint connection seat 3.4 is provided with a joint connection hole. One end of the joint shaft 3.3 passes through the joint connection hole and the joint bearing 3.5 in sequence and is fixedly connected to the joint fastener 3.6. The joint bearing seat 3.1 and the joint connection seat 3.4 are respectively fixedly connected to the corresponding sub-stage 1. The end of the joint bearing 3.5 is provided with a sealing cover 3.2, which is used to prevent leakage of the lubricating medium and intrusion of external contaminants, ensuring the normal working state of the joint bearing 3.5.

[0032] See attached Figure 4 The joint connection seat 3.4 includes an end plate and two fixed plates vertically 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 holes 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 driving mechanism 2 is driven by an underwater oil cylinder, and the joint mechanism 3 is made of stainless steel, thereby ensuring that the flexible rolling stage can be used in normal environments and underwater environments.

[0034] In this embodiment, the flexible rolling stage further includes a limiting connection block 4. A plurality of limiting connection blocks 4 are sequentially arranged between two adjacent sub-stages 1 along their length direction to limit the rolling 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 sub-stage 1 located in the front, the connecting plate 4.4 is horizontally arranged and one end is fixedly connected to the sub-stage 1 located in the rear, the connecting frame 4.3 and the connecting plate 4.4 are provided with arc-shaped strip holes of the same shape, the connecting frame 4.3 and the connecting plate 4.4 are arranged parallel to each other, and the limiting shaft 4.5 passes through the arc-shaped strip holes 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 sub-stage 1 is flipped, the connecting plate 4.4 will move relative to the connecting frame 4.3, and the moving distance will not exceed the length of the arc-shaped strip hole, thereby limiting the flipping angle of the sub-stage 1.

[0037] The position-limiting connection block 4 further includes a welding plate 4.1, an adjustment pad 4.2, and an adjustment bolt. The two welding plates 4.1 are arranged in parallel and are fixedly connected to the sub-stage 1 and the connecting frame 4.3 located in the front, respectively. The adjustment pad 4.2 is arranged between the two welding plates 4.1. Threaded holes are provided at corresponding positions on the welding plates 4.1 and the adjustment pad 4.2. The adjustment bolt engages with the threaded holes on the welding plates 4.1 and the adjustment pad 4.2 to securely connect the welding plates 4.1 and the adjustment pad 4.2. The adjustment pad 4.2 can be replaced. Adjustment pads 4.2 of different thicknesses can be selected according to actual conditions, thereby changing the connection position between the connecting frame 4.3 and the connecting plate 4.4, thereby changing the flip angle limit of the sub-stage 1.

[0038] In this embodiment, multiple elastic buffers are spaced along the length of two adjacent sub-stages 1. The two ends of these elastic buffers are fixed to the rear end of the front sub-stage 1 and the front end of the rear sub-stage 1, respectively. These elastic buffers cushion the impact between the sub-stages 1 when they move from the folding position to the unfolding position, and also ensure a smoother transition from the unfolding position to the folding position.

[0039] By adopting the above technical solution disclosed in the present invention, the following beneficial effects are obtained:

[0040] This invention provides a flexible, multi-stage, parallel-driven roll-up mechanism that can flexibly adjust the stage shape and position according to actual needs, achieving flexible and diverse stage presentations. When deployed, the stage lies flat, suitable for normal use; when rolled up, it tilts upward, meeting the needs of specialized performances. It is suitable for use in both normal and underwater environments.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be considered within the scope of protection of the present invention.
