[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] according to Figure 1 , Figure 2 As shown, an embodiment of the present application proposes a safe ladder device for beam construction in a beam yard, comprising a support frame 1, a moving wheel assembly 2 is provided at the lower end of the support frame 1, an inclined step ladder assembly is provided at the upper end of the support frame 1, and safety guardrails 4 are provided on both sides of the support frame 1 relative to the length direction of the step ladder assembly. The step ladder assembly comprises an integrated folding ladder 3 detachably connected to the support frame 1, and a working platform 5 connected to the support frame 1 is provided at the upper end of the integrated folding ladder 3. During the actual installation process, the prefabricated integrated folding ladder 3 can be directly stretched after the support frame 1 is installed and formed through the telescopic function, so that the integrated folding ladder 3 is stably installed on the support frame 1, and the integrated folding ladder 3 after installation cannot be telescoped or deformed, thereby ensuring stability.

[0025] It should be noted that the provision of the integrated folding ladder 3 enables the prefabricated integrated ladder to be directly transported to the designated installation site during the ladder transportation process, and then the space occupied during transportation can be reduced by folding and telescoping, thereby improving transportation efficiency. In the actual installation process, the prefabricated integrated ladder can be stretched and fixed at the designated position of the support frame 1, thereby ensuring the integrity after installation, and improving safety and stability. The provision of the working platform 5 makes it convenient for the operator to stand stably on the working platform 5 for construction when using the utility model, thereby improving safety.

[0026] The moving wheel assembly 2 comprises four universal wheels evenly spaced at the bottom end of the support frame 1. The universal wheels are provided with a manual brake device. The specific structure may refer to the existing brake universal wheels.

[0027] A push handle 6 is provided at one end of the support frame 1 away from the integrated folding ladder 3, so that the operator can apply force to the structure when the whole structure is moved, thereby improving operability.

[0028] The above-mentioned integrated folding ladder 3 can be an existing segmented hinged folding ladder, and the folding part is provided with a fastening mechanism, which is convenient for bending the ladder into a ladder of a shorter length, and is convenient for transportation and installation.

[0029] like Figure 3 As shown, specifically, the integrated folding ladder 3 includes two telescopic beams arranged in parallel, and a plurality of horizontal pedals 8 are evenly spaced between the two telescopic beams. The telescopic beams are simultaneously extended and retracted to achieve the effect of occupying less space and facilitating transportation.

[0030] Moreover, the telescopic beam includes a plurality of telescopic parts 7 whose sizes gradually decrease from bottom to top, and two adjacent telescopic parts 7 are movably connected, and the plurality of horizontal pedals 8 are connected to the plurality of telescopic parts 7 in a one-to-one correspondence. That is to say, the plurality of telescopic parts 7 can be slid and telescoped in turn. When the limit block is snapped, the telescopic beam is telescoped to the longest state, and at this time the telescopic beam can be accurately and stably fixedly installed with the support frame 1 to ensure the overall stability.

[0031] Regarding the detachable structure between the telescopic beam and the support frame 1, specifically, the telescopic beam is provided with a first positioning column at both ends, and the support frame 1 is provided with a first positioning groove that is snap-fitted with the first positioning column, and the snap-fit ​​connection is achieved by plugging, and in order to further improve the support stability of the middle part of the telescopic beam and prevent shaking or offset, the two sides of the telescopic beams that are far away from each other are provided with a second positioning column, and the support frame 1 is provided with a second positioning groove that is snap-fitted with the second positioning column. The first positioning column cooperates with the first positioning groove to ensure that the telescopic beam is in the longest extension state, and the telescopic beam is stably fixed on the support frame 1, ensuring that the horizontal pedal 8 remains in a horizontal state, and the stability is high.

[0032] In order to further improve stability and safety, an anti-skid layer is provided on the upper end of the horizontal pedal 8 to prevent the operator from slipping when stepping on the horizontal pedal 8.

[0033] The circumferential edges of the working platform 5 that are not adjacent to the integrated folding ladder 3 are all provided with the safety guardrails 4 to ensure that there is no risk of falling when the operator steps on the working platform 5, thereby improving the safety of the structure.

[0034] Moreover, the above-mentioned safety guardrail 4 includes a retractable guardrail that is detachably connected to the above-mentioned support frame 1. The specific structure of the safety guardrail 4 is a plurality of plug-in posts arranged at intervals, and a flexible connecting chain or connecting belt is provided between the plurality of plug-in posts. The corresponding positions of the support frame 1 and the working platform 5 are provided with connecting holes that cooperate with the above-mentioned plug-in posts, so that the entire safety guardrail is easy to install and transport, thereby improving efficiency.

After the processing is completed, the on-site pre-assembly, inspection and correction are carried out; the bottom longitudinal and transverse main frame structure is installed, and the elevation is in the same horizontal plane. The relative positions are adjusted, and the lengths of the two diagonals are equal; the reserved holes are screwed and fixed; the vertical and oblique frames are installed on the lower longitudinal beams, and then the upper longitudinal beams and oblique braces of the vertical frame are installed to complete the overall assembly of the support frame 1. The working platform 5 is installed at the upper end of the support frame 1 by means of bolt fixing; the prefabricated integrated folding ladder 3 is installed to the support frame 1, and is clamped between the first positioning column, the first positioning hole, the second positioning column and the second positioning hole, and other positions are fixed by means of a bolt structure to ensure that the integrated folding ladder 3 is stably installed on the support frame 1; the moving assembly is installed at the bottom frame, and the relative positions are adjusted; the safety guardrails 4 on both sides of the ladder are respectively installed at the oblique frame beside the pedal and at the edge of the working platform 5, and the installation method is to lock the socket with a reserved socket; finally, a hand push handle 6 is added to the support frame 1.
