The fixed guardrail 401 is not foldable, and the overturning guardrail 402 is foldable.
Further, the method comprises the following steps: the fixed guard rail 401 vertically surrounds the frame assembly 2 on three sides by means of vertical frames and panel assemblies. Namely, the vertical frame and panel assembly comprises a vertical frame and a panel; the vertical frame is as the braced frame of vertical panel, the panel is as vertical guard plate, the panel is used for preventing that the instrument from falling from the high altitude and smashing injury ground personnel.
The bottom end of the fixed guardrail 401 is connected with the framework component 2 in a fastening mode, so that the detachable installation of the fixed guardrail is realized, and the fixed guardrail is convenient to manufacture and assemble.
(fig. 9) the top end of the frame of the fixed guardrail 401 is hinged to the bottom end of the overturning guardrail 402; the hinge mode is as follows: the inward 90-degree overturning function of the overturning guardrail 402 can be realized.
