Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 6, the portable platform for the close-up inspection in the ballast tank of the ship comprises a rectangular bottom platform 1, wherein the front side edge of the bottom platform 1 is rectangular and is hinged with a plurality of movable railing posts 2, and the movable railing posts 2 can rotate on a vertical plane on which the front side edge of the bottom platform 1 is positioned; a first bolt hole is formed in the front right part of the bottom platform 1, and a locking device 3 for detachably fixing the bottom platform 1 on a ship bottom plate penetrates through the first bolt hole; the left front part of the bottom platform 1 is provided with an eye ring;
each movable railing post 2 is provided with N guy rope passing openings;
when the movable railing post 2 is positioned in the horizontal direction, the eye ring is connected with one end of a stay cable 4, and the other end of the stay cable 4 is connected with a connecting piece fixed on the side wall of the cabin; the connecting piece is positioned at the upper right of the bottom platform 1;
when the movable railing posts 2 are positioned in the vertical direction, the eye loops are connected to N handrails 6, and the N handrails 6 respectively penetrate through N handrail through holes on each movable railing post 2 and then are connected to a cabin inner handrail 7 positioned at the right end of the bottom platform 1;
the hinged part of the movable railing post 2 is provided with a limiting device.
The number of the movable railing post 2 is 2.
N≥2。
The limiting device comprises at least one second bolt hole 9 formed in the side wall of the hinged position of the movable railing post 2 and a bolt 8 with a tongue penetrating through the second bolt hole 9; the left side surface of the hinged part of the movable railing post 2 is provided with a vertical angle steel 10 and a stop dog 11 which limit the rotation of the movable railing post 2.
The locking device 3 comprises a hook 15 formed by connecting a straight rod and a hook, wherein the top of the straight rod is provided with an external thread and is screwed into one wing-shaped nut 12 after penetrating through a bolt hole from bottom to top; the hook is limited below the cabin bottom plate.
A rubber sleeve 16 is embedded at the hook.
The invention can be used in the following scenarios: the space between a cabin balustrade 7 and another cabin (or another area within the same cabin) is inconvenient to stand, and thus the present invention is required to establish access. When the guardrail device is used, assuming that the standing area of the guardrail 7 is positioned at the right side, the stay cable 4 can be fixed on the wall of the right bulkhead, and then the bottom platform 1 is slowly put down by using the pulling force of the stay cable 4, so that the left end of the bottom platform 1 is supported in the left standing area. Utilize locking device 3 to fix bottom platform 1, then the manual work lifts up movable railing post 2 on the bottom platform 1 and up to vertical position, passes the rotation spacing fixed that has tongue bolt 8 with movable railing post 2 towards the right side in second bolt mouth 9 department, and angle steel 10 and dog 11 can restrict movable railing post 2 and rotate towards the left side. At this time, the guy 6 is inserted. The invention provides a guy rope 6 on one side only, which is suitable for the case that the other side has a bulkhead, and if the other side has no bulkhead, the guy rope 6 can be arranged on the other side. When the bottom platform 1 needs to be retracted, the bolt with the tongue 8 is pulled out, the wing-shaped nut 12 is rotated to release the locking device 3, the movable railing post 2 is put down, and the platform is lifted by using the stay cable 4. In addition, a second bolt opening 9 can be arranged, so that the movable railing post 2 can play a role of limiting the upward swing of the latch 8 when the latch 8 is inserted into the lower second bolt opening 9 under the condition of being laid down. The locking device 3 may further comprise a support bracket 13 and a guide sleeve 14, both the bracket 13 and the sleeve 14 being fixed to the cabin floor. The cushion 5 may be secured to the underside of the base platform 1 by bolts and nuts.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
