[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See attached document Figures 1-5 The foldable power construction aerial work platform safety fence device of this embodiment includes a work platform 1, a foldable guardrail 2, a side guardrail 3, and a safety gate 4.

[0029] See attached document Figure 4 Multiple No. 1 plug holes 11 are equally spaced on both sides of the work platform 1. The No. 1 plug holes 11 on both sides are arranged along the length direction of the work platform 1. A first through hole 12 is opened on both sides of the work platform 1. The first through hole 12 on both sides passes through the multiple No. 1 plug holes 11 on both sides respectively.

[0030] See attached document Figure 3 and Figure 4 Two sets of folding guardrails 2 are provided on both sides of the work platform 1, including a lower guardrail 21 and an upper guardrail 22. The lower guardrail 21 and the upper guardrail 22 are hinged together. A plug block 23 that matches the first plug hole 11 is fixedly installed at the bottom of the lower guardrail 21. A second through hole 24 is provided on the plug block 23. A first connecting rod 5 is inserted into the first through hole 12 and the second through hole 24. The first connecting rod 5 is fixed with a nut.

[0031] See attached document Figure 3 and Figure 4 The upper guardrail 22 and the lower guardrail 21 are each provided with a connecting groove 25 on one side. The connecting groove 25 is a trapezoidal structure. The side guardrail 3 is set between the two sets of folding guardrails 2 and is located on one side of the work platform 1. Connecting blocks 31 are fixedly installed on both sides of the side guardrail 3. The connecting blocks 31 are trapezoidal structures and are adapted to the connecting groove 25.

[0032] See attached document Figure 4 The top of the side guardrail 3 is provided with a No. 3 insertion hole 32, and one side of the top of the two upper guardrails 22 is provided with a No. 4 insertion hole 27. A No. 2 connecting rod 6 is inserted into the No. 3 insertion hole 32 and the No. 4 insertion hole 27, and the No. 2 connecting rod 6 is fixed with a nut.

[0033] See attached document Figure 2 and Figure 5 The safety door 4 is hinged to the other side of the work platform 1, and a handle 41 is fixedly installed on the outer end of the top of the safety door 4. A first rectangular hole 42 is provided on both sides of the top of the safety door 4, and a second rectangular hole 26 is provided on the other side of the top of the two upper guardrails 22. The first rectangular hole 42 and the second rectangular hole 26 are compatible. A connector 7 is provided in the first rectangular hole 42 and the second rectangular hole 26 on the same side. The connector 7 includes a rod 71, which is compatible with the first rectangular hole 42 and the second rectangular hole 26. An installation hole 72 is provided on the rod 71, and a spring 73 is fixedly installed in the installation hole 72. A snap-fit ​​block 74 is connected to the outer end of the spring 73.

[0034] During the assembly of the safety railing device for the foldable power construction aerial work platform 1, the safety gate 4 is first moved to make it parallel to the work platform 1. At this time, the handle 41 is in contact with the ground to support the safety gate 4. Then, the plug-in blocks 23 at the bottom of the two sets of lower guardrails 21 are inserted into the first plug-in holes 11 on both sides of the work platform 1, so that the first through hole 12 on the work platform 1 and the second through hole 24 on the plug-in block 23 are aligned on the same axis. Then, the first connecting rod 5 is respectively... Insert the folding guardrail 2 into the first through hole 12 and the second through hole 24 on both sides, and fix it with nuts to achieve the connection between the folding guardrail 2 and the working platform 1. Then, move the upper guardrail 22. Since the upper guardrail 22 and the lower guardrail 21 are hinged, the upper guardrail 22 can rotate around the lower guardrail 21. Move the upper guardrail 22 so that the upper guardrail 22 and the lower guardrail 21 are in the same vertical plane. At this time, the connecting grooves 25 on the upper guardrail 22 and the lower guardrail 21 on the same side are coaxial. At this time, the side Align the connecting blocks 31 on both sides of the side guardrail 3 with the connecting slots 25 on the upper guardrail 22 and lower guardrail 21 on both sides, and insert them until the third insertion hole 32 on the side guardrail 3 is coaxially aligned with the fourth insertion hole 27 on the upper guardrail 22 on both sides. At this time, insert the second connecting rod 6 into the third insertion hole 32 and the fourth insertion hole 27, and fix it with nuts to achieve the connection between the side guardrail 3 and the two sets of folding guardrails 2. Then, move the safety door 4 so that the safety door 4 is perpendicular to the working platform 1, and press... The locking block 74 is retracted into the mounting hole 72. At this time, the spring 73 is in a compressed state. Then, the insertion rod 71 is inserted into the first rectangular hole 42 on the safety door 4 and the second rectangular hole 26 on the upper guardrail 22. During the insertion process, the inner walls of the first rectangular hole 42 and the second rectangular hole 26 obstruct the locking block 74, preventing it from popping out. Under the elastic action of the spring 73, when the locking block 74 pops out from the mounting hole 72, the connection between the safety door 4 and the two sets of folding guardrails 2 is realized.

[0035] In this embodiment, a folding design is adopted. The lower guardrail 21 is connected to the working platform 1 through the plug-in block 23 and the first plug-in hole 11, and is fixed by the first connecting rod 5 and the nut. The upper guardrail 22 is hinged to the lower guardrail 21 and can be flexibly rotated to the same vertical plane. Then, through the connection block 31 of the side guardrail 3 and the connection groove 25, as well as the fixation of the second connecting rod 6 and the nut, the overall structure can be quickly assembled and disassembled, which greatly improves construction efficiency and saves time and labor costs. The safety door 4 is hinged to the working platform 1 and supported by the handle 41. It is connected to the folding guardrail 2 through the connector 7 with the spring 73 and the snap-fit ​​block 74, which ensures the safety of the workers when working at height and effectively prevents accidental falls.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
