[0009] By adopting the above technical solution, when the seat frame is slid, the seat frame is controlled by the hydraulic cylinder to slide along the length direction of the guide rail.

[0010] Preferably, longitudinal limit plates are provided at both the front and rear ends of the guide rail, and the longitudinal limit plates are used to longitudinally limit the guide rail.

[0011] By adopting the above technical solution, the longitudinal limit plate can effectively prevent the guide rail from shaking due to the influence of sea breeze, and the longitudinal limit plate can effectively ensure the stability of the guide rail during offshore operation, thereby effectively ensuring the stability of the seat frame during sliding on the guide rail. When floating objects at sea are recovered to the seat frame, the seat frame will not shake randomly, thereby effectively ensuring the recovery and fixation of floating objects at sea after salvage at sea and the rescue operation of opening the cabin under high sea conditions.

The rubber pads have a certain elasticity. When the floating objects at sea fall between the rubber pads, the rubber pads will tightly clamp the floating objects at sea in the middle, thereby effectively ensuring the stability of the floating objects at sea after being recovered on the frame. At the same time, the rubber pads are soft in texture, and the floating objects at sea will not be damaged when they are recovered between the rubber pads.

[0036] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0037] Example:

[0038] The present application discloses a frame and operating platform for recovering floating objects at sea. Figure 1 and Figure 2 , including a salvage platform 1, a recovery seat 2 and an operating platform 3. The recovery seat 2 and the operating platform 3 are both installed on the main deck at the rear of the salvage platform 1. The recovery seat 2 is slidably installed on the salvage platform 1, which allows the position of the recovery seat 2 on the salvage platform 1 to be flexibly adjusted. After the salvage of floating objects at sea is completed, the installation position of the recovery seat 2 can be adaptively adjusted according to the specific recovery situation of floating objects at sea. A lifting gantry 18 is installed at the end of the salvage platform 1. The lifting gantry 18 is provided with corresponding equipment for lifting floating objects at sea. The floating objects at sea that fall on the sea are lifted and recovered through these equipment and the lifting gantry 18.

[0039] In this arrangement, the recovery seat 2 is slidably installed on the salvage platform 1. The specific position of the recovery seat 2 can be adaptively adjusted according to the specific recovery situation of the floating objects at sea. This design can effectively improve the convenience of the staff in recovering floating objects at sea, and can effectively avoid the problem of unstable recovery caused by various factors that are easily affected when recovering floating objects at sea, which is conducive to improving the efficiency of recovering floating objects at sea, and can effectively ensure the recovery, fixation and cabin opening rescue operations of floating objects at sea after salvage at sea under high sea conditions.

[0040] Specifically, refer to Figure 2 , Figure 3 as well as Figure 4 The recovery seat 2 includes a guide rail 21 and a seat frame 22. There are two guide rails 21. The two guide rails 21 are installed in parallel on the main deck of the salvage platform 1. The two guide rails 21 are connected together by multiple I-beams to form an integral structure. The seat frame 22 is rectangular in shape. Rollers 4 are installed between the bottom of the left and right sides of the seat frame 22 and the guide rails 21. The seat frame 22 is connected to the guide rails 21 by the rollers 4, and the seat frame 22 is slidable on the guide rails 21 by the rollers 4.

[0041] Specifically, refer to Figure 2 and Figure 3 A hydraulic cylinder 5 is installed along one side of the ship below the seat frame 22, one end of the hydraulic cylinder 5 is connected to one side of the seat frame 22, and the other end of the hydraulic cylinder 5 is connected to a fixed seat 6 on the guide rail 21. The fixed seat 6 is in a rectangular shape as a whole and is welded to the guide rail 21. Specifically, when the seat frame 22 is slid, the seat frame 22 is controlled by the hydraulic cylinder 5 to slide along the length direction of the guide rail 21.

[0042] Further, refer to Figure 3 The front and rear ends of the guide rail 21 are provided with longitudinal limit plates 7, which can limit the longitudinal position of the guide rail 21, thereby effectively preventing the guide rail 21 from shaking due to the influence of the sea breeze. The longitudinal limit plates 7 can effectively ensure the stability of the guide rail 21 during the offshore operation, thereby effectively ensuring the stability of the seat frame 22 during the sliding process on the guide rail 21. When the floating objects at sea are recovered on the seat frame 22, the seat frame 22 will not shake randomly, thereby effectively ensuring the recovery and fixation of the floating objects at sea after salvage at sea and the rescue operation of the cabin opening under high sea conditions.

[0043] Specifically, refer to Figure 3, the longitudinal limiting plate 7 includes a first plate body 71 and a second plate body 72. Both the first plate body 71 and the second plate body 72 are in the shape of a cuboid. The first plate body 71 is arranged vertically, the second plate body 72 is arranged horizontally, and the first plate body 71 and the second plate body 72 are welded together, and the whole is in an "L" - shaped structure. The first plate body 71 is welded to the end of the guide rail 21, and the second plate body 72 is welded to the mounting seat at the bottom of the guide rail 21. At the same time, a pull rod 8 is obliquely arranged between the first plate body 71 and the second plate body 72, and the two ends of the pull rod 8 are respectively welded to the first plate body 71 and the second plate body 72. The first plate body 71 and the second plate body 72 are used to effectively strengthen the tightness of the connection between the guide rail 21 and the mounting seat, which is beneficial to enhancing the connection strength between the guide rail 21 and the mounting seat, further ensuring the stability of the installation of the guide rail 21. When the seat frame 22 slides on the guide rail 21, the seat frame 22 is not prone to jumping. At the same time, the pull rod 8 can effectively strengthen the stability of the connection between the first plate body 71 and the second plate body 72, and then make the effect of the first plate body 71 and the second plate body 72 in strengthening the connection strength between the guide rail 21 and the mounting seat better.

[0044] Furthermore, referring to Figure 3 and Figure 4 , in order to enable the seat frame 22 to stay and stop as it moves on the guide rail 21 and effectively ensure the stability of the locking of the seat frame 22 on the guide rail 21, a locking mechanism 9 is arranged between the seat frame 22 and the guide rail 21. When the position of the seat frame 22 on the guide rail 21 reaches the designated position, the locking mechanism 9 is used to lock the bottom of the seat frame 22 on the guide rail 21, thereby ensuring the stability of the seat frame 22 during the stopping process on the guide rail 21, so that the marine floating object can accurately fall onto the seat frame 22 for recovery.

[0045] Specifically, referring to Figure 3 and Figure 4 , the locking mechanism 9 includes a locking seat 91, a threaded sleeve 92, a screw rod 93 and a magnetic plate 94. There are four locking seats 91 in total. The four locking seats 91 are distributed in pairs on the left and right sides of the bottom of the seat frame 22, and the two locking seats 91 on the same side of the seat frame 22 are distributed at the front and rear ends of the seat frame 22. The locking seat 91 is in an inverted "U" - shaped structure as a whole. The locking seat 91 is buckled on the guide rail 21, and the top of the locking seat 91 is connected to the bottom of the seat frame 22 through a corresponding connecting seat. The threaded sleeve 92 is integrally formed on the side wall of the locking seat 91 in the horizontal direction. A circular screw hole is penetrated through the threaded sleeve 92. The screw rod 93 is inserted vertically into the screw hole, and the upper and lower ends of the screw rod 93 respectively extend out of the threaded sleeve 92. The magnetic plate 94 is welded to the top of the screw rod 93 in the horizontal direction.

[0046] Since the guide rail 21 is made of metal, when the seat frame 22 needs to be locked on the guide rail 21, the screw 93 is screwed to make the screw 93 rise until the magnetic plate 94 on the top of the screw 93 is magnetically attracted to the guide rail 21. In this state, the seat frame 22 and the guide rail 21 are locked by the magnetic attraction between the magnetic plate 94 and the guide rail 21. When the lock between the seat frame 22 and the guide rail 21 needs to be released, the screw 93 is screwed downward to make the magnetic plate 94 detach from the guide rail 21.

[0047] Further, refer to Figure 2 and Figure 3 , the seat frame 22 is provided with multiple groups of rubber pads 10, which are evenly distributed on the seat frame 22 at circumferential intervals. When the floating objects at sea are recovered on the seat frame 22, the floating objects at sea are supported and fixed by these rubber pads 10 after being salvaged and recovered. The rubber pads 10 have a certain elasticity. When the floating objects at sea fall between these rubber pads 10, these rubber pads 10 will tightly clamp the floating objects at sea in the middle, thereby effectively ensuring the stability of the floating objects at sea being recovered on the seat frame 22. At the same time, the rubber pads 10 are relatively soft in texture, and the floating objects at sea will not be damaged when they are recovered between these rubber pads 10.

[0048] Specifically, the rubber pads 10 are all fixed on the seat frame 22 via the support seat 11 , the support seat 11 is welded to the seat frame 22 , and the rubber pads 10 are fastened to the support seat 11 via fastening bolts.

[0049] Reference Figure 1 and Figure 2 The operating platform 3 includes a cabin top operating platform 12 and a cabin side operating platform 13. If the lifting and recovery posture of the floating objects at sea is good and the floating objects at sea are in a vertical state, the staff can open the cabin on the cabin side operating platform 3 to rescue the astronauts; if the floating objects at sea are tilted, which affects the side opening of the cabin, the staff can open the cabin on the cabin top operating platform 12. The use of the cabin top operating platform 12 and the cabin side operating platform 13 can further increase the convenience of the staff in the process of recovering floating objects at sea, which is conducive to further improving the efficiency of recovering floating objects at sea, and can effectively ensure the recovery, fixation and cabin opening rescue operations of floating objects at sea after salvage at sea under high sea conditions.

[0050] Specifically, refer to Figure 1 and Figure 2, spiral staircases 14 are installed on the left and right sides of the cabin top working platform 12, and a platform ladder 15 is installed on one side of the cabin side working platform 13. Workers can go up and down the cabin top working platform 12 and the cabin side working platform 13 through these spiral staircases 14 and platform ladders 15. The cabin side working platform 13 and the two spiral staircases 14 are connected by corresponding connecting rods, and the two connecting rods are used to connect the cabin top working platform 12 and the cabin side working platform 13 as a whole. At the same time, a circular manhole 16 is opened through the middle of the cabin top working platform 12, and the manhole 16 is used for workers to open the cabin on the top of the floating objects at sea. Guardrails 17 are also added around the cabin top working platform 12, and these guardrails 17 are used to provide safety protection for the workers on the cabin top working platform 12.

[0051] The implementation principle of a floating object salvage and recovery frame and operating platform in the present application embodiment is as follows:

[0052] The recovery seat 2 is slidably installed on the salvage platform 1. The specific position of the recovery seat 2 can be adaptively adjusted according to the specific recovery situation of the floating objects at sea. This design method can effectively improve the convenience of the staff when recovering floating objects at sea, and can effectively avoid the problem of unstable recovery caused by various factors when recovering floating objects at sea, which is conducive to improving the efficiency of recovering floating objects at sea, and can effectively ensure the recovery, fixation and cabin opening rescue operations of floating objects at sea after salvage at sea under high sea conditions. At the same time, the longitudinal limit plate 7 can effectively ensure the stability of the guide rail 21 during the offshore operation process, and can effectively ensure the stability of the frame 22 during the sliding process on the guide rail 21. When floating objects at sea are recovered on the frame 22, the frame 22 will not shake, and can effectively ensure the recovery, fixation and cabin opening rescue operations of floating objects at sea after salvage at sea under high sea conditions.

[0053] If the floating objects at sea are in a good posture for lifting and recovery, and the floating objects at sea are in a vertical state, the staff can open the cabin on the cabin side operating platform 3 to rescue the astronauts; if the floating objects at sea are tilted, which affects the side opening of the cabin, the staff can open the cabin on the cabin top operating platform 12. The use of the cabin top operating platform 12 and the cabin side operating platform 13 can further increase the convenience of the staff in the process of recovering floating objects at sea, which is conducive to further improving the efficiency of recovering floating objects at sea, and can effectively ensure the recovery, fixation and cabin opening rescue operations of floating objects at sea after salvage at sea in high sea conditions.
