[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In this embodiment:

[0028] A marine hydraulic lifting work platform, such as Figures 1-4 As shown, the system includes a stable base 1, a lifting platform 2, a standing platform 3, two sets of guardrails 5, and several sets of first ladders 9. A rotating handle 6 is rotatably provided on one side of the guardrail 5. Both ends of the rotating handle 6 are fixed with take-up rollers 7, and steel cables 8 are wound around the take-up rollers 7. Two sets of first sliders 10 are fixed on the side of the several sets of first ladders 9 near the guardrail 5. The several sets of first ladders 9 are engaged and slid with the first sliders 10 respectively, and are arranged at equal intervals. A second ladder 11 is provided on the side of the first ladder 9 away from the guardrail 5, and two sets of second sliders 12 are fixed on the side of the second ladder 11 near the first ladder 9, and are engaged and slid with the first ladder 9.

[0029] The structure includes a rotating handle 6, a take-up roller 7, and a steel cable 8. Rotating the handle 6 causes the take-up rollers 7 at both ends to rotate synchronously, thereby enabling the steel cable 8 to be wound up and down. This allows the steel cable 8 to be easily wound up and down the second ladder 11. Several sets of first ladders 9 are engaged and slid together by first sliders 10 and are set at equal intervals. The second ladder 11 is engaged and slid together with the first ladders 9 by second sliders 12. This structural design ensures flexible connection and relative sliding between several sets of first ladders 9 and second ladders 11.

[0030] See Figure 1 , Figure 2 and Figure 3 A lifting platform 2 is provided on one side of the top of the stable base 1, and a standing platform 3 is fixed on the top of the lifting platform 2. Protective railings 5 ​​are fixed on both sides of the top of the standing platform 3.

[0031] The lifting platform 2 is arranged on one side of the top of the stable base 1, and the standing platform 3 is fixed on the top of the lifting platform 2. The structure design makes the whole working platform have clear layering and function division. In the relatively complex and possible shaking working environment of the ship, the protection bar 5 can effectively prevent the construction personnel from falling due to accidents, greatly reduce the safety risk in the construction process, protect the personal safety of the construction personnel, and make the whole marine hydraulic lifting working platform have the height adjustment function and perfect safety protection performance.

[0032] Referring to Figure 1 , Figure 2 and Figure 4 , the bottom of the second ladder 11 is fixed with a support plate 13, and the top of the support plate 13 is fixed with a hanging rod 14 on both sides;

[0033] In the use process of the ladder, especially when the construction personnel climbs or descends, the support plate 13 can bear a certain pressure and weight, preventing the bottom of the second ladder 11 from deforming or being damaged due to uneven force, thereby prolonging the service life of the ladder and improving the reliability of its use. When the second ladder 11 needs to be lowered, the lifting of the hanging rod 14 can be conveniently controlled by the winding of the wire rope 8 by the take-up roller 7, thereby driving the second ladder 11 to descend synchronously.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the top of the two groups of hanging rods 14 is fixed with a ring structure and is respectively tied and fastened with the two groups of wire ropes 8;

[0035] In the use process of the marine hydraulic lifting working platform, especially during the ladder lowering operation, the wire rope 8 needs to bear the weight and tension of the hanging rod 14 and the second ladder 11 and other components. The tying and fastening mode of the ring structure and the wire rope 8 can ensure that the wire rope 8 will not easily fall off the hanging rod 14, avoiding safety accidents caused by loose connection and ensuring the stability and safety of the whole lowering process.

[0036] Referring to Figure 1 and Figure 2 , the top of the stable base 1 is fixed with a pressing plate 4 away from the lifting platform 2, and the pressing plate 4 is arranged in correspondence with the support plate 13;

[0037] The abutting structure provides a stable support point for the second ladder 11, prevents the second ladder 11 from continuing to shake or be unstable after descending, ensures the safety of the ladder during use, and enables the construction personnel to more safely pass through the ladder for up and down work. Through the corresponding relationship, the second ladder 11 can be more easily ensured to descend to an accurate position, improving the accuracy of installation and the convenience of operation.

[0038] Referring to Figure 4 The cross sections of the two groups of second sliding blocks 12 and the plurality of groups of first sliding blocks 10 are in a “T” shaped structure.

[0039] During use of the ladder, whether it is relative sliding between the first ladders 9 or sliding between the second ladder 11 and the first ladders 9, the “T” shaped structure can effectively prevent the sliding blocks from derailing in the sliding rails, greatly improving the stability and reliability of the ladder sliding, and ensuring the safety of the construction personnel when using the ladder.

[0040] The implementation principle of the embodiment is as follows: first, the stable base 1 is stably placed on a designated position, and then the external control center is started to start the lifting platform 2, so that the lifting platform 2 drives the standing platform 3 at the top thereof to rise. When the construction personnel stand on the top of the standing platform 3, the protection bars 5 on both sides and the plurality of groups of first ladders 9 and second ladders 11 provide a protection function for the construction personnel. Then, when part of the construction personnel need to fall, and another part of the construction personnel are performing maintenance, the rotating handle 6 can be rotated to drive the wire winding rollers 7 at both ends thereof to rotate, so that the wire winding rollers 7 bundle and release the steel cables 8 sleeved outside thereof, and then the steel cables 8 synchronously release the hanging rods 14 bundled therewith. Since the steel cables 8 provide traction to the support plates 13 at the bottom of the second ladders 11 through the hanging rods 14, when the steel cables 8 are released, the second ladders 11 are synchronously lowered. The second ladders 11 are connected to the first ladders 9 away from the protection bars 5 through the second sliding blocks 12, the plurality of groups of first ladders 9 are connected to each other through the first sliding blocks 10, and the first ladders 9 close to the protection bars 5 are connected to the two groups of protection bars 5 through the first sliding blocks 10. Thus, the plurality of groups of first ladders 9 and the second ladders 11 are slowly lowered. When the second ladders 11 are lowered to the bottom end, the support plates 13 at the bottom thereof abut against the abutting plates 4, thereby providing stable support for the second ladders 11 and the plurality of groups of first ladders 9. Finally, part of the construction personnel can perform down-to-earth work through the ladder group composed of the plurality of groups of first ladders 9 and the second ladders 11.
