Description

Technical Field

[0001] This utility model relates to the field of ladder technology, and in particular to a ladder for steel structure installation. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] Ladders are used during steel structure installation to assist operators in moving up and down, making it easier to carry out steel structure construction and installation at heights. However, existing ladders have certain inconveniences in use.

[0004] First, most existing ladders are fixed structures, which cannot adapt to the installation requirements of steel components with different cross-sectional dimensions. The ladders are not stable enough when working at heights, which poses a safety hazard. In addition, the existing adjustable ladders have complicated adjustment mechanisms and low on-site disassembly and assembly efficiency.

[0005] Therefore, we propose a ladder for steel structure installation. Utility Model Content

[0006] In view of the existing technology, most of the existing ladders are fixed structures, which cannot adapt to the installation requirements of steel components with different cross-sectional dimensions. The ladders are not stable enough during high-altitude operations, which poses safety hazards. In addition, the existing adjustable ladders have complicated adjustment mechanisms and low on-site disassembly and assembly efficiency. Therefore, this utility model provides a steel structure installation ladder.

[0007] The technical solution adopted by this utility model is as follows: a steel structure installation ladder, including a first handrail section, a second handrail section, and a connecting section. A horizontal step is provided on one outer surface of both the first and second handrail sections. A first connecting sleeve is provided between the first and second handrail sections. A fixing sleeve is provided on the upper outer surface of the second handrail section. An L-shaped section is provided on the upper outer surface of the fixing sleeve. An upper fixing section is provided in front of the L-shaped section, and a lower fixing section is provided below the upper fixing section. A second connecting sleeve is provided between the upper and lower fixing sections. A telescopic section is provided on one outer surface of both the upper and lower fixing sections.

[0008] Furthermore, a first connecting pin is provided on one side of the outer surface of the first connecting sleeve, and a first connecting hole is provided on both sides of the outer surface of the first handrail tube segment and the second handrail tube segment.

[0009] Furthermore, a connector is fixedly connected to one end of the outer surface of the fixed sleeve, a first fixing pin is provided on one side of the outer surface of the fixed sleeve, and a second fixing pin is provided on one side of the outer surface of the connector.

[0010] Furthermore, a second connecting pin is provided on one outer surface of the second connecting sleeve, and a second connecting hole is provided on both outer surfaces of the upper fixed pipe section and the lower fixed pipe section.

[0011] Furthermore, the telescopic tube section is movably connected to a built-in square tube in the middle, a limit pin is provided on one side of the outer surface of the telescopic tube section, and limit holes are provided on both sides of the outer surface of the built-in square tube.

[0012] Furthermore, both the first handrail section and the second handrail section are welded to the cross step, and the first handrail section is connected to the second handrail section through the first connecting sleeve.

[0013] Furthermore, the upper fixed pipe section is connected to the lower fixed pipe section through the second connecting sleeve.

[0014] The beneficial effects of this utility model are:

[0015] This invention allows for the initial connection and installation of a first handrail section and a second handrail section via a first connecting sleeve. A first connecting pin is then inserted into a first connecting hole to secure the first and second handrail sections. The telescopic section can then be adjusted according to the steel structure's cross-sectional dimensions to extend the internal square tube. A limiting pin is inserted into a limiting hole to secure the internal square tube. Furthermore, the telescopic section can extend outwards to create upper and lower fixing sections, which are then clamped to the upper and lower ends of the steel structure. Furthermore, the second connecting sleeve connects the upper and lower fixed pipe sections, and the second connecting pin is inserted into the second connecting hole to fix the upper and lower fixed pipe sections. During use, the telescopic pipe section on the lower fixed pipe section is connected to the plug pipe head through the connecting pipe section for fixation, and the telescopic pipe section on the upper fixed pipe section is fixed to one end of the L-shaped pipe section. The upper and lower fixed pipe sections are wrapped around and fixed to the steel structure, which has high stability and is relatively safe during use. When disassembling, the connecting sleeves can be removed one by one through the pin, which is convenient for disassembly, assembly and storage. Attached Figure Description
