Steps 7 are fixedly mounted at equal intervals on the inner end of the ladder body 1. A reinforcement plate 6 is fixedly mounted on the rear end of the ladder body 1, and the lower end of the reinforcement plate 6 is fixedly mounted on the rear end of the base plate 4; a mounting rod 9 is fixedly mounted on the inner end of the storage plate 2, and the mounting rod 9 is rotatably mounted on the inner end of the handrail 8, and a limit rod 12 is provided on the right side of the storage plate 2, so that workpieces and tools that need to be used can be temporarily placed on the upper part of the pushed-open storage plate 2, which is convenient for storing tools and is flexible and convenient to use;

[0028] The inner end of the base 3 is symmetrically provided with slots 13, the positions of the slots 13 corresponding to the positions of the universal wheels 5, the inner end of the base 3 is fixedly provided with a motor 14, the output end of the motor 14 is fixedly provided with a gear 15, the outer end of the gear 15 is meshedly connected with a rack 16, and the end of the rack 16 is fixedly provided with a support plate 17. The support plate 17 is arranged at the lower side of the slot 13, which is convenient for moving the ladder body 1 and can also provide a stable support when in use, thereby improving the safety of use.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, when the pressure vessel manufacturing ladder device is used, the base 3 is first placed at the position where the ladder is placed for manufacturing and processing pressure vessels, and then the staff pushes the ladder body 1 to rotate the universal wheel 5 at the lower end of the bottom plate 4, and pushes the universal wheel 5 to a position corresponding to the slot 13, and then pushes the ladder body 1 in the direction of the base 3, and the universal wheel 5 is pushed into the inside of the slot 13 along the slope of the front end of the base 3. After the front and rear four sets of universal wheels 5 are all pushed into the inside of the slot 13, the pushing can be stopped. At this time, the bottom plate 4 is in the On the upper side of the base 3, the motor 14 is started, and the output end of the motor 14 drives the gear 15 to rotate when rotating, and the gear 15 meshes with the rack 16 when rotating, driving the front and rear sets of racks 16 to move toward each other.
