DETAILED DESCRIPTION

[0023] The embodiment of the present application provides a movable operating platform, which solves the problem that during the construction process, construction workers must remove the protective guardrail on one side of the frame before they can move the operating platform up and down, thereby reducing the potential safety hazard of falling from a height during the process of moving the operating platform up and down. The embodiment is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 , 2As shown, a movable operating platform disclosed in an embodiment of the present application includes a portal frame 1, a cross support 2, a fixed scaffolding board 3, an openable scaffolding board 4, a protective guardrail 5 and a universal wheel 6. The cross support 2 is arranged on the portal frame 1, and the upper part of the portal frame 1 is supported and installed with the fixed scaffolding board 3 and the openable scaffolding board 4. The two portal frames 1 are provided with a protective guardrail 5; two portal frames 1 are provided, and the two portal frames 1 are set up in parallel, and each includes two vertical poles 10, a cross arm 11, two simple ladders 12 and a reinforcement part 13; screws 101 are welded on the vertical poles 10, and the screws 101 are locked by nuts; the top ends of the two vertical poles 10 are connected to the cross arm 11 by welding to form a portal frame body.

[0025] Two simple ladders 12 are arranged oppositely on the main body of the portal frame and are welded and connected by a reinforcement part 13. The simple ladder 12 includes a plurality of step beams 121 and a handrail 122. One end of the handrail 122 is connected to the vertical pole 10 and the other end is connected to the cross arm 11. The step beam 121 is horizontally welded between the vertical pole 10 and the handrail 122.

[0026] The reinforcement part 13 includes a crossbeam 131 and a plurality of connecting columns 132. The connecting columns 132 are evenly and vertically welded to the crossbeam 131. The crossbeam 131 is fixedly connected between the handrails of the two simple ladders 12. The connecting columns 132 are welded to the crossarm 11, which can stabilize the platform body and increase the load-bearing capacity.

[0027] The cross support 2 includes two tie rods 20, which are connected at the intersection by rivets. Both ends of the tie rods 20 are flat and have through holes. The diameter of the through holes at both ends of the tie rods 20 is larger than the outer diameter of the screw 101. The screw 101 passes through the through holes at both ends of the tie rods 20. The cross support 2 is arranged between the two vertical poles 10 of the two portal frame 1 bodies, thereby increasing the rationality and stability of the overall structure of the mobile operating platform.

[0028] The protective guardrail 5 includes four horizontal columns 50 and four vertical columns 51. The four vertical columns are respectively fixedly connected to a vertical pole 10 and are coaxially arranged with the vertical pole 10. A horizontal column 50 is vertically connected between the tops of two adjacent vertical columns 51, which can reduce the risk of construction workers falling when working on the platform.

[0029] like Figure 3 , 4 As shown in Figure 5, the fixed scaffolding board 3 and the retractable scaffolding board 4 are rectangular structures and hooks 30 are welded at both ends. The fixed scaffolding board 3 and the retractable scaffolding board 4 are connected to the crossbeam 11 of the main body of the portal frame 1 through the hooks 30, and the upper surfaces of the fixed scaffolding board 3 and the retractable scaffolding board 4 are covered with steel mesh panels 31.

[0030] The retractable scaffolding board 4 includes an outer square tube 40, an openable part 41, a fixed part 42, a connecting steel sheet 43 and a hinge 44. The openable part 41 and the fixed part 42 are both rectangular structures; the openable part 41 is rotatably connected to the fixed part 42 through the connecting steel sheet 43 and the hinge 44. The openable part 41 can be opened and closed at an angle of 0°-180°; a hook 410 is provided on the openable part 41, and the hook 410 is movably connected to the outer square tube 40. The construction personnel opens the hook 410 on the outer square tube 40, pushes the retractable part 41 upward from the inside of the platform, and then realizes the open state, and then climbs onto the mobile operating platform through the simple ladder 12; after the construction personnel climb onto the mobile operating platform, the retractable part can be closed by re-placing the hook 410 on the outer square tube 40.

[0031] A universal wheel 6 is disposed at the bottom end of each upright pole 10 , and a locking mechanism is disposed on the universal wheel 6 , which facilitates the movement and use of the operating platform while preventing the platform from being unstable due to the sliding of the universal wheel 6 .

[0032] The implementation principle of this embodiment is: a scaffolding board is set as a structure with one part being openable and the other part being fixed. Construction workers complete the operation of going up and down the platform by opening the openable part of the scaffolding board from the inside of the platform, so as to solve the problem of having to remove the protective guardrail on one side of the frame when moving the operating platform up and down, thereby reducing the safety hazard of falling from a height during the process of moving the operating platform up and down.
