[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a movable steel inclined ladder for ship section construction, including: an inclined ladder frame 1 and a construction frame 5; the construction frame 5 is set on one side of the inclined ladder frame 1, and the construction frame 5 and the inclined ladder frame 1 are fixedly connected; pulleys 14 are set on the four corners of the bottom of the inclined ladder frame 1; crossbars 15 are set on both sides of the inclined ladder frame 1, and push handles 16 are set on the crossbars 15; several steel treads 3 are set on the inclined ladder frame 1; fixing blocks 2 are set on the bottom side of the inclined ladder frame 1; and an inclined ladder base plate 4 is set on the bottom side of the inclined ladder frame 1.

[0023] The inclined ladder frame 1 has a structural inclined plate 11 on its side, a crossbar 15 connected in the middle of the structural inclined plate 11, and a bottom structural bar 12 at the bottom of the inclined ladder frame 1.

[0024] The overall strength of the inclined ladder frame 1 is enhanced by the structural inclined plate 11 and the bottom structural rod 12.

[0025] The fixed block 2 has a rotating screw groove in the middle, and a screw 21 is provided inside the rotating screw groove. The bottom of the screw 21 extends out of the bottom of the fixed block 2. A base is provided at the bottom of the screw 21, and a friction layer is provided at the bottom of the base. A rotating head 22 is provided on the top of the screw 21.

[0026] Once the device is moved to a suitable position, the rotating head 22 can be rotated to make the base contact the ground, thereby fixing the device in place. The friction layer increases friction with the ground to prevent slippage.

[0027] The steel pedal 3 is provided with a number of anti-slip strips 31, and a number of drainage holes 32 are evenly arranged between the anti-slip strips 31.

[0028] The anti-slip strip 31 prevents slipping when the steel pedal 3 is wet, and the drainage hole 32 allows water to flow down the steel pedal 3, preventing water from accumulating on the steel pedal 3.

[0029] The inclined ladder base plate 4 has a bottom groove, and a counterweight 41 is installed inside the bottom groove.

[0030] The counterweight 41 is designed to prevent the overall center of gravity of the device from shifting when personnel are on the construction platform 51, thus playing a role in balancing the center of gravity.

[0031] The construction frame 5 is provided with a construction platform 51 on the top, and a platform side rod 52 is provided on the side of the construction frame 5. The platform side rod 52 is fixed to the inclined ladder frame 1. The construction frame 5 is provided with a platform inclined plate 53.

[0032] Construction workers move to the construction platform 51 via the steel step 3 and carry out construction operations on the construction platform 51. The construction platform 51 is unobstructed, making it convenient for personnel to carry out construction operations.

[0033] The inclined ladder frame 1 is equipped with a handrail 13.

[0034] The working principle and usage process of this utility model are as follows: The device is moved to a suitable position by the pulley 14, and the rotating head 22 can be rotated to make the base contact the ground, thereby fixing the device. The friction layer increases the friction with the ground to prevent slipping. Construction personnel move to the construction platform 51 through the steel pedal 3 and carry out construction operations through the construction platform 51. There are no obstacles on the construction platform 51, which facilitates the construction operations. The counterweight 41 prevents the overall center of gravity of the device from shifting when personnel are on the construction platform 51, and plays a role in balancing the center of gravity. The anti-slip strip 31 on the steel pedal 3 prevents slipping when the steel pedal 3 is wet. The drain hole 32 allows water on the steel pedal 3 to flow down and prevents water from accumulating on the steel pedal 3.
