AI Technical Summary
The existing pre-welded integrated ladders are inconvenient to disassemble the pin shaft at the connection of the outer jacket section and have poor mobility. Each coat section needs to be equipped with four ladders, resulting in waste of manpower and material resources and prolonged production cycle.
The removable jacket joint ladder structure is adopted, and the ladder is fixed by hooks, jaws, pin limits and cross beams to achieve flexible installation and disassembly of ladders.
This design allows the ladder to position the fixed points according to the operator's body shape, which facilitates the later breaking of the pin shaft, reduces production costs and material waste, and improves the universality of the ladder.

Abstract
Description
Technical Field
[0001] The utility model relates to a novel detachable outer shell section climbing ladder structure, belonging to the technical field of tower cranes. Background Art
[0002] The existing pre-welded integrated ladder is used for the later disassembly of the outer section and the standard section, which is convenient for construction workers to climb and smash the pins. Under the premise of ensuring safety first, construction machinery also needs to have the characteristics of high mobility and low difficulty of operation to ensure the completion of the project on schedule. At present, in order to solve the problem of inconvenient disassembly of the pins at the outer section connection, most of the integrated welded ladders are used on the market, that is, the outer section and the ladder are welded into one piece, and then hoisted to the construction site for on-site assembly. This will have the following problems. First, since the ladder and the segments are pre-welded, each person's body shape is different. If the welding position does not take into account the particularity, it will be unfavorable for later adjustment and poor mobility; second, the pre-welded integrated ladder only serves the current tower crane. When other tower cranes on the site use sleeves of similar size specifications but without welded ladders, they also encounter the inconvenience of disassembly of the pins and need to be manually smashed, which will be unfavorable for the advancement of later work; third, the pre-welded integrated ladder needs to be equipped with four ladders on each sleeve, which will cause a waste of manpower and material resources, and at the same time extend the production cycle, which is undoubtedly contrary to the engineering concept. Utility Model Content
[0003] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a novel detachable outer-section ladder structure, which adopts hooks, claws, pin shaft limiters and crossbeam fixation. Under the premise of preventing the hook from being unhooked and ensuring construction safety, it provides front-line construction personnel with space for adaptability and flexible construction.
[0004] The utility model is realized through the following technical scheme: a novel detachable outer sleeve section ladder structure, comprising a ladder hook, a baffle, a claw and a ladder, wherein a ladder hook is arranged at the top of the ladder, a claw is arranged at the bottom of the ladder, a baffle is arranged on the ladder hook, the baffle is fixed to the ladder hook through a pin shaft I and a bolt, the ladder hook is hung on the upper crossbeam of the outer sleeve section, and the claw at the bottom of the ladder is fixed to the lower crossbeam of the outer sleeve section.
[0005] The clamping claw is fixed by a pin shaft II, and an R-shaped pin is arranged on the pin shaft II to prevent the clamping claw from sliding out of the cross beam under the outer sleeve section.
[0006] Pull rings are arranged on the pin shaft I and the pin shaft II.
[0007] The clamping claw is welded to the bottom of the ladder through a backing plate.
[0008] The ladder hook and the clamping claw are wound with soft material.
[0009] The soft material is a cloth tape or an adhesive tape.
[0010] The beneficial effects of the utility model are as follows: the ladder can effectively locate the fixed point according to the subjective self-positioning of the operator, which is convenient for the later smashing and dismantling of the pin shaft. At the same time, because the ladder is detachable, the use of the ladder does not need to be equipped with each outer shell section like the original welded one-piece ladder, saving production costs and avoiding unnecessary material waste. In addition, the ladder can also be used on outer shell sections of similar specifications to dismantle the pin shaft, and has strong universality. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0019] like Figures 1 to 4 A novel detachable outer-section ladder structure is shown, comprising a ladder hook 1, a baffle 2, a claw 3 and a ladder 4. The ladder hook 1 is arranged on the top of the ladder 4, the claw 3 is arranged on the bottom of the ladder 4, the ladder hook 1 is provided with a baffle 2, the baffle 2 is fixed to the ladder hook 1 by a pin shaft Ⅰ 5 and a bolt 6, the ladder hook 1 is hung on the upper crossbeam 7 of the outer section, and the claw 6 at the bottom of the ladder 4 is fixed to the lower crossbeam 8 of the outer section.
[0020] The clamping claw 6 is fixed by a pin shaft II 9, and an R-shaped pin 10 is provided on the pin shaft II 9 to prevent the clamping claw 6 from sliding out of the cross beam 8 under the outer sleeve section.
[0021] Pull rings 11 are provided on the pin shaft I5 and the pin shaft II9.
[0022] The clamping claw 3 is welded to the bottom of the ladder 4 via a backing plate 12 .
[0023] The ladder hook 1 and the claw 3 are wound with soft material.
[0024] The soft material is a cloth tape or an adhesive tape.
[0025] The installation method of the new detachable external ladder applied to the outer jacket section is as follows:
[0026] First, hang the hook 1 on the upper crossbeam 7 of the assembled outer section on the ground, and simply fix the baffle 2 on the hook with bolts 6. The nut does not need to be completely screwed, so that it is easy to install it quickly during high-altitude operations. The four ladders are operated in this way. During high-altitude operations, the personnel determine the fixed position according to their own body characteristics so that the pin can be smashed and removed later. After the position is determined, the pin Ⅰ5 with a pull ring will completely fix the baffle 2 on the upper crossbeam 7 of the outer section, and insert the cotter pin to prevent the upper end from being unhooked. The lower end of the ladder is fixed to the lower crossbeam 8 of the outer section with a claw 3, and is also fixed with a pin Ⅱ9 with a ring. An R-shaped pin 10 is inserted to prevent the claw from slipping out of the beam. The remaining ladders are installed in this way. When disassembling the ladder, the upper fixed pin can be removed first, and then the lower fixed pin can be removed. The ladder is rotated around the ladder cross tube with the upper hook 1 as the center of rotation, leaving enough translation space for the lower end to ensure that the lower claw 3 can be smoothly withdrawn.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
