Detailed Implementation

[0028] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0029] Example 1:

[0030] An assembled safety ladder is suitable for projects such as water diversion tunnels, deep foundation pit excavation, valve well installation, and sand and gravel aggregate processing system construction. Figure 1 It includes a fixed section 1, a ladder section 2 and a support section 3 that can be connected in sequence. The number of ladder sections 2 can be set in any number of groups, and the number of ladder sections 2 can be set freely according to site requirements.

[0031] The fixed section 1, the ladder body section 2 and the support section 3 each include a tread 4, a frame 5, a handrail 6 and a connecting section 7. The tread 4 and the handrail 6 are both installed on the frame 5.

[0032] Specifically, the frame 5 consists of six galvanized square steel bars, including an upper rod 52 and a lower rod 51 located on both sides of the pedal 4. The upper rod 52 consists of one galvanized square steel bar, and the lower rod 51 consists of two galvanized square steel bars, making the width of the lower rod 51 greater than that of the upper rod 52, which facilitates the connection of the handrail support rod 61. Both ends of the pedal 4 are connected to the upper rod 52 and the lower rod 51 by bolts or welding, making the double-layer rod structure more stable. The handrail 6 is connected to the lower rod 51 by the handrail support rod 62 through connectors or welding.

[0033] Connecting segment 7 is formed by removing material from frame 5. Adjacent segments of connecting segment 7 are assembled and connected using connectors, such as... Figure 7 The connecting segment 7 is formed by cutting off half the width of the end positions of the upper rod 52 and the lower rod 51. When splicing, the two sets of connecting segments 7 form a complete square rod. The connectors include bolt assemblies 8, and 8 sets of connectors are provided at each connecting segment 7.

[0034] like Figure 2 One end of the fixed section 1 is provided with an extension section connecting part 11, and the other end is provided with a connecting section 7. Preferably, several bolt holes are provided at the position of the extension section connecting part 11, and the extension section is detachably connected by bolts. The extension section connecting part 11 is located on the lower rod body 51, and the extension section connecting part 11 is connected to the extension section with M10*50 bolts.

[0035] The extended section is used to connect the top of the ladder with the ground, such as... Figure 5 , Figure 6 The extended section can be either a hook-type extended section 12 or a straight-lay extended section 13. The hook-type extended section 12 can be fastened to the steel pipe, while the straight-lay extended section 13 can be laid on a flat surface. Install the appropriate extended section according to the site requirements to meet the fixing requirements.

[0036] A horizontal section 61 is provided at the top of the handrail 6 of the fixed section 1 to improve safety.

[0037] Both ends of the ladder section 2 are provided with connecting sections 7; one end of the support section 3 is provided with connecting section 7, and the other end is equipped with support foot 31. The support foot 31 is preferably made of round steel pipe, which is low in cost, and is connected to the frame 5 by welding.

[0038] When using it, first measure the height on site and determine the clamping method of the extended section and how many sections of the ladder body are needed. Then assemble the fixed section, ladder body section and support section on flat ground. If the height is very small, the fixed end and support end can be assembled directly. Optionally, the handrails between adjacent sections can be connected with bolts, and corresponding bolt holes are set on the handrails.

[0039] Example 2:

[0040] Based on Example 1, such as Figure 8 Pedal 4 is an adjustable pedal, whose length can be adjusted according to usage needs to further improve flexibility.

[0041] Specifically, the pedal 4 includes an outer sleeve 41, an inner insert 42 that can move within the outer sleeve 41, and bolt holes 43 provided on both the outer sleeve 41 and the inner insert 42. The bolt holes 43 are arranged in two rows of four groups, which can have two length states. More length states can be adjusted by setting more bolt holes. The length adjustment effect is achieved by adjusting the corresponding bolt hole docking and connecting with bolts.

[0042] The preferred material for pedal 4 is galvanized square steel with inner and outer layers.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
