[0024] Further, if Figure 1 As shown, a fixed ring is provided in the middle of the bridge ladder frame 1, and the end of the safety cable 16 away from the first winch 13 is connected to the fixed ring; a rotating shaft is provided at the end of the bridge ladder frame 1 close to the tower frame 11, and when the traction cable 15 lowers the bridge ladder frame 1, the bridge ladder frame 1 is lowered along the rotating shaft; when the traction cable 15 retracts the bridge ladder frame 1, the bridge ladder frame 1 is pulled up along the rotating shaft; a plurality of steps 2 are hinged on the bridge ladder frame 1, and the steps 2 always remain horizontal as the lowering angle of the bridge ladder frame 1 changes.

[0025] In this embodiment, a fixing ring is welded in the middle of the main structure of the bridge ladder frame 1, and the end of the safety cable 16 away from the first winch 13 is hinged on the fixing ring. As the bridge ladder frame 1 rises or falls, the safety cable 16 always keeps the bridge ladder frame 1 taut to prevent the bridge body from suddenly falling after the traction cable 15 is disconnected, causing casualties.

[0026] Preferably, one end of the bridge ladder frame 1 is fixedly connected to the tower frame 11 and is perpendicular to the tower frame 11. A rotating shaft is provided on the side of the bridge ladder frame 1 close to the tower frame 11, and the raising or lowering of the bridge ladder frame 1 is realized by the rotating shaft; a plurality of steps 2 are hinged at intervals on the bridge ladder frame 1, and the control steps 2 do not change with the horizontal angle of the bridge ladder frame 1, and the plurality of steps 2 always remain horizontal to facilitate construction workers to board.

[0027] Further, if Figure 1 and Figure 2 As shown, a first guardrail 3 is arranged along the length direction of the bridge ladder frame 1, and a safety door 4 is arranged at the end of the bridge ladder frame 1 away from the tower frame, and the safety door 4 is opened unidirectionally from the outside to the inside; a first straight ladder 6 is arranged along the length direction of the base frame 5, and an inclined support 7 is fixedly connected to the end of the base frame 5 away from the first straight ladder 6, and a rubber gasket is laid on the upper surface of the inclined support 7, and fixed clamping plates 8 are connected to both sides of the inclined support 7; an electric slip ring 9 is fixedly connected to the top of the base frame 5, and the end of the electric slip ring 9 away from the base frame 5 is vertically connected to the tower frame 11, and the bridge ladder frame 1 is fixedly connected to the tower frame 11, so that the electric slip ring 9 drives the bridge ladder frame 1 to rotate.

[0028] In this embodiment, preferably, a plurality of first guardrails are fixedly installed on the bridge ladder, the plurality of first guardrails are arranged continuously end to end, and a safety door is provided at one end of the bridge ladder away from the tower frame, and the safety door opens unidirectionally from outside to inside.

[0029] The bridge ladder frame 1 is a channel steel frame structure, which ensures the stability and strength of the entire bridge body and provides sufficient installation space for the steps. The first guardrail 3 and the safety door 4 are used to ensure the safety of passengers.

[0030] A first straight ladder 6 is fixedly installed along the length direction of the base frame 5, and an inclined support 7 is welded to the base frame 5 away from the arrangement direction of the first straight ladder 6. A rubber gasket is laid on the upper surface of the inclined support 7, and fixed clamps 8 are connected to both sides of the end of the inclined support 7. When the bridge ladder frame 1 is below the bridge ladder frame 1, the bridge ladder frame 1 abuts against the inclined support 7 and is clamped with the fixed clamp 8.

[0031] Preferably, an electric slip ring 9 is fixedly provided on the top of the base frame 5, and a tower frame 11 is connected to the electric slip ring 9. The tower frame 11 and the base frame 5 are both arranged in the vertical direction. The electric slip ring 9 drives the tower frame 11 to rotate, thereby driving the bridge ladder frame 1 to rotate.

[0032] The base frame 5 is mainly composed of I-beams. According to stress analysis, the bottom connected to the platform can be equipped with an elbow plate or the toe end can be enlarged and rounded to make the stress distributed along the free edge and reduce the stress concentration. An inclined support is set on the lowering side to lock the lowering angle of the bridge body. The angle can be determined in advance according to the design requirements. Rubber gaskets are arranged on the upper surface of the inclined support 7 as a buffer to prevent the bridge body from rigidly contacting it. Fixed clamps 8 are set on both sides to limit the horizontal movement of the bridge body. The first straight ladder is used as a boarding passage for people to pass.

[0033] By sending instructions at the remote control end, the electric slip ring 9 cooperates with the first winch 13 and the second winch 14 to accurately control the rotation and lifting action of the bridge ladder frame 1, allowing personnel to board the platform from a distance, solving the problem that it is inconvenient for maintenance ships to contact and dock.

[0035] In this embodiment, preferably, a second straight ladder 12 is fixedly installed along the length direction of the tower frame 11, a second winch 12 is arranged at the top of the tower frame 11, and a second guardrail 18 is installed around the second winch 12. The traction cable 15 is led out from the first winch 13 and then connected to the end of the bridge ladder frame 1 after passing through the second winch 14. The second winch 14 provides auxiliary power. The main power of the traction cable 15 comes from the first winch 13. The first winch 13 is arranged on the small platform 10 of the bridge ladder frame.

[0036] Preferably, the tower frame 11 is also composed of I-beams, and the overall reinforcement method of frame plus diagonal bracing is adopted, which needs to meet the structural strength of the normal operation of the winch group; the small platform 10 serves as an extension of the bridge channel and a support for the winch base; the second straight ladder 12 and the second guardrail 18 ensure the safety of the passengers during maintenance.

[0037] Preferably, the traction cable 15 and the safety cable 16 play a double protective role. Even if the traction cable 15 fails, it can be restored to a recovered state through the safety cable 16, and it will not hover for a long time to cause uncontrollable risks, thereby ensuring the safe operation of the bridge body; a placement frame is set within the rotation radius of the bridge body on the top of the platform, which serves as a support for the cantilever structure of the bridge body when the trestle is in the recovered state. It is spliced ​​by angle steels, and rubber gaskets or sleepers are arranged on the top surface to avoid rigid contact with the bridge body.

[0038] The working steps of the unmanned platform remote control trestle device of this application are as follows: When the bridge ladder 1 is in the retracted state, the bridge ladder 1 abuts against the placement frame 17, the end of the bridge ladder 1 is connected to the traction cable 151, and the middle is connected to the safety cable 16. At this time, the bridge ladder 1 does not abut against the inclined support 7 on the base frame 5; When the bridge ladder 1 is in operation, the electric slip ring 9 drives the tower frame 11 to rotate, thereby driving the bridge ladder 1 to rotate, releasing the traction cable 15, causing the bridge ladder 1 to rotate downward, and placing the bridge ladder 1 against the fixed card plate of the inclined support 7, and the personnel open the safety door 4 to complete boarding.

[0039] The remote control trestle device based on the unmanned platform solves the risks of collision between the operation and maintenance ship and the platform and the ups and downs of the ship by setting up the bridge ladder 1. The safety of boarding operations is improved through structural design and the setting of safety equipment, and the range of options for operation and maintenance ships is increased, expanding its business scope. This application simplifies the construction and installation process. The trestle adopts a reasonable lightweight design, which is conducive to the selection of a smaller power winch group and reduces costs; in working state, it can meet the requirements of 3 people boarding at the same time and the displacement deformation range of the lowest end is controllable, which improves the applicability and stability of the remote control trestle device in complex sea conditions.
