DETAILED DESCRIPTION
[0029] In order to have a clearer understanding of the technical features, objects and effects of the present application, the specific embodiments of the present application will be described in detail with reference to the drawings.
[0030] As Figures 1-6As shown, the working ladder for construction workers in areas with frequent water level changes of the present invention includes a platform 10, steel piles 6, and a floating pontoon 1. Multiple steel piles 6 are installed on the water-facing side of the platform 10. The floating pontoon 1 is moored on the water-facing side of the platform 10. Energy-dissipating tires 5 are installed on the outer side of the floating pontoon 1, and a support frame 2 is fixedly installed on the inner side of the floating pontoon 1. A first roller 4 and a neodymium magnet 3 are installed on the support frame 2. The first roller 4 abuts against the steel piles 6, and the neodymium magnet 3 maintains a 1-3 mm gap from the surface of the steel pile 6. A pedestrian ladder 7 is installed on the upper part of the floating pontoon 1, and the pedestrian ladder 7 is connected to the platform 10 via an adjustable horizontal step inclined ladder 8.
[0031] The first roller 4 can roll up and down along the surface of the steel pile 6, which limits the distance between the floating pontoon 1 and the steel pile 5, keeping the distance between the neodymium magnet 3 and the surface of the steel pile 6 between 1 and 3 mm, and the attraction force of the neodymium magnet 3 on the steel pile 6 is not less than 300 kg. The walkway 7 is a segmented structure, with each segment being 3 m high, and adjacent walkway segments are connected by mortise and tenon joints. The adjustable horizontal step inclined ladder 8 is a variable slope inclined ladder. The adjustable horizontal step inclined ladder 8 includes a lower support rod 801, an upper support rod 802, a main beam 803, an auxiliary beam 804, steps 805, axle rods 806, and a railing 807. The main beam 803 is set between the lower support rod 801 and the upper support rod 802. The railing 807 is set on the upper part of the main beam 803. The main beam 803 and the auxiliary beam 804 are connected by hinges through the steps 805, the upper support rod 802, and the lower support rod 801. The lower end of the lower support rod 801 is provided with a second roller 9, which can roll on the platform 10. The upper support rod 802 is fixed on the walkway 7. The adjustable horizontal step inclined ladder 8 can automatically change its slope as the walkway 7 moves up and down, while the steps 805 remain horizontal.
[0032] The installation principle and usage method of this invention are as follows:
[0033] The floating platform 1 serves as the supporting foundation, with a walkway 7 placed on it. An adjustable horizontal step ladder 8 connects the platform 10 and the walkway 7. The floating platform 1 is attached to the steel piles 6 of the platform 10 by the attraction of neodymium magnets 3 and the first rollers 4, allowing it to move up and down along the steel piles 6. This integrated structure ensures the safe movement of personnel between the platform 10 and the ship. The floating platform 1 has a displacement of approximately 60 tons. Energy-dissipating tires 5 are installed on the outer side (the side closest to the ship) of the floating platform 1. A support frame 2 is welded to the inner side of the floating platform 1 at the position corresponding to the steel piles 6. The support frame 2 is connected to the first rollers 4 and the neodymium magnets 3. The first rollers 4 are directly supported on the steel piles 6. The neodymium magnets 3 are positioned approximately 1-3 mm away from the surface of the steel piles 6, and the attraction force of the neodymium magnets 3 on the steel piles 6 should be no less than 300 kg.
[0034] The walkway 7 is a segmented structure, with each segment approximately 3 meters high. The upper and lower segments of the walkway 7 are connected by mortise and tenon joints and pins. When the height of the walkway 7 cannot accommodate the height difference with the platform 10, it can be adjusted by adding or removing segments. The adjustable horizontal step inclined ladder 8 is a variable slope inclined ladder, including a lower support rod 801, an upper support rod 802, a main beam 803, an auxiliary beam 804, steps 805, axles 806, and railings 807. The lower support rod 801 is equipped with a second roller 9, which can roll on the platform 10. The upper support rod 802 is fixed to the walkway 7. The main beam 803 and the auxiliary beam 804 are connected by hinges through the steps 805, the upper support rod 802, and the lower support rod 801. The adjustable horizontal step inclined ladder 8 can automatically change its slope as the walkway 7 moves up and down, while the steps 805 remain horizontal.
[0035] This invention also provides a method for installing and using a ladder for workers to ascend and descend in construction work on water structures in areas with frequent water level changes, comprising the following steps:
[0036] S1. Measure the spacing of the steel piles 6, connect the support frame 2 to the pontoon body on one side of the floating pontoon 1 according to the measured spacing, install the first roller 4 and the neodymium magnet 3, and then place the floating pontoon 1 against the side of the steel piles 6.
[0037] S2. Place the walkway 7 on the floating platform 1 and fix it so that the total height of the walkway 7 is greater than the height of the platform 10. When the height of the walkway 7 is too high or too low, it is necessary to disassemble or add ladder sections to adapt to the changes.
[0038] S3. Fix the upper support rod 802 of the finished adjustable horizontal step inclined ladder 8 to the walking ladder 7, and place the lower support rod 801 on the platform 10.
[0039] S4. When dismantling, first remove the adjustable horizontal step ladder 8, then remove the walkway ladder 7, and then move the floating platform 1 to the next working point and adjust the position of the support.
