[0019] like Figures 3 to 4 , Figure 7 As shown, the platform device 1 includes the following parts: Vertical enclosure frame 11: serves as the core skeleton of the platform and is used to connect other components; The platform frame 12, which is horizontally fixed to the bottom of the enclosure frame 11, forms the "base" of the platform; Platform plate 13, horizontally fixed to the top of platform frame 12: provides a working surface (material is anti-slip steel plate); The hanging plates 14 are fixedly connected to the top left and right sides of the bulkhead frame 11: The hanging plates 14 are used in conjunction with the guide rail web plate 5 at the top of the side rail 4 of the hatch bulkhead 3. The entire platform device 1 is fixedly installed on the guide rail web plate 5 at the top of the container side rail 4 through the hanging plates 14 (no welding is required to avoid the risk of loosening of the joints); the front and rear sides of the hanging plates 14 are respectively connected with reinforcing ribs 15: to improve the tensile strength of the hanging plates 14 and prevent the hanging plates 14 from deforming; The upper hinge plate 16, which is vertically fixed to the top of the enclosure frame 11, is used to hinge with the guardrail device 2. A kickboard 17, vertically fixed to the perimeter of the enclosure frame 11 and perpendicularly connected to the platform panel 13, prevents tools / debris from falling from the edge of the platform. The step bars 18 are horizontally connected to the rear side of the enclosure frame 11 and are distributed in a vertical linear array: to facilitate workers to climb up and down the platform; The longitudinal support 19, which is fixed to the rear side of the bulkhead frame 11 and abuts against the hatch bulkhead 3, enhances the stability of the platform device 1; wherein, the rear end of the longitudinal support 19 is wrapped with a rubber sleeve 110 to prevent scratching the surface of the hatch bulkhead 3.

[0020] like Figures 5 to 6 As shown, the guardrail device 2 includes the following parts: Vertically arranged edge guardrail frame 21: serves as the core skeleton of the guardrail and is used to connect other components; Longitudinal guardrail frames 22, which are fixed to the left and right sides of the edge guardrail frame 21, improve the safety of the platform device 1 from the side. The lower hinge plate 23, which is vertically fixed to the bottom of the edge guardrail frame 21 and hinged to the upper hinge plate 16, is used to hinge to the platform device 1. The work entrance / exit 24 is located in the middle of the edge guardrail frame 21: Workers enter the platform device 1 through the work entrance / exit 24; A horizontal interception chain 25 is placed at the work entrance / exit 24 and can be quickly disassembled at one end: to prevent personnel from falling accidentally; The protective chains 26, which are longitudinally inclined and installed on the left and right sides of the edge guardrail frame 21, further enhance the side protection; one end of the protective chain 26 is connected to the top of the edge guardrail frame 21, and the other end of the protective chain 26 is connected to the front top of the enclosure frame 11.

[0022] like Figure 6 , Figure 8 As shown, the bottom of the edge guardrail frame 21 is connected to a pin 210 near the lower hinge plate 23 via an anti-detachment chain 29. The lower hinge plate 23 has a socket 211 for use with the pin 210. When the pin 210 is inserted into the socket 211, the guardrail device 2 is in a vertical state. When the guardrail device 2 is flipped to the vertical state, the height of the edge guardrail frame 21 is the same as the height of the container ship guardrail 6.

[0023] The working principle of this utility model is as follows: like Figure 9As shown, the working platform is moved to the hatch bulkhead 3 where the positioning pin 7 is located by hoisting the hanging plate 14, and then the hanging plate 14 is fixedly installed on the guide rail web plate 5 at the top of the container side rail 4. Open the guardrail device 2 to the vertical edge protection state, insert the pin 210 into the pin 210 hole, and lock the guardrail device 2. The work entrance / exit 24 is blocked by the intercepting chain 25 to prevent personnel from falling accidentally. like Figure 10 As shown, when the positioning pin 7 is being repaired, the interception chain 25 is released, and the staff enters the platform device 1 from the work entrance / exit 24 and moves up and down using the step bar 18; like Figure 11 As shown, when the hatch needs to be closed for testing, the pin 210 needs to be pulled out and the guardrail device 2 needs to be stored in the platform device 1 to avoid interference with the hatch during testing. After testing, the guardrail device 2 can be opened to the vertical edge protection state.

[0024] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
