[0026] Example 1

[0027] As shown in Figures 1-6, a portable railing for the movable deck of a roll-on / roll-off (Ro-Ro) ship is installed on the car deck 5 of the Ro-Ro ship. The movable deck 5 has lashing holes 51. The railing includes a post 1, a base plate 2, a movable plate 3, and a pin 4. A slot 11 is formed on the side of the bottom end of the post 1. The bottom end of the post 1 is inserted into the lashing hole 51, and the slot 11 engages with the edge of the lashing hole 51. The slot 11 is used to clamp the edge of the lashing hole 51 on the upper, lower, and one side of the post 1, preventing the post 1, or the entire railing, from jumping. The base plate 2 is fixed to the bottom end of the post 1 and to one side above the slot 11. The base plate 2 is located above the movable deck 5, and the two are in contact and fit together. The base plate 2 has a limiting hole 21, the length of which is slightly larger than the length of the slot 11. This allows the pin 4 to be inserted into the limiting hole 21 while simultaneously restricting the railing from moving horizontally to the other side. The movable plate 3 is provided with a movable hole 31. The movable plate 3 is sleeved on the column 1 through the movable hole 31, and the movable plate 3 can be raised and lowered relative to the column 1. The movable plate 3 is located above the base plate 2. The pin 4 is vertically fixed to the bottom end of the movable plate 3. The pin 4 is inserted into the limiting hole 21 and the binding hole 51 in sequence. The bottom side of the pin 4 is close to the edge of the binding hole 51, thereby restricting the entire railing from moving to the other side of the movable deck 5 (or the other side of the slot 11).

[0028] In this embodiment, the movable plate 3 is also provided with a fixing hole 32, and the pin 4 is fixed in the fixing hole 32. Preferably, the fixing hole 32 can be a round hole, and the pin 4 can be a cylindrical pin, with the top of the pin 4 welded into the fixing hole 32, thus making the structure more stable. Alternatively, the fixing hole 32 can also be a countersunk threaded hole, and the pin 4 can be a bolt or stud, with the top of the pin 4 threadedly connected and fixed in the fixing hole 32. Although this solution is feasible to a certain extent, the structural stability is weaker compared to the previous solution. In this way, it is convenient to fix the movable plate 3 and the pin 4 into a whole. The diameter of the fixing hole 32 is 10mm; the diameter of the pin 4 is 8mm, the length is 46mm, and the material is Q235A. The movable plate 3 is ear-shaped, or in other words, it is a combination of a semi-circular plate and a square plate; its length is 79mm, its width is 60mm, and its thickness is 10mm. The movable hole 31 is a round hole, or a hole composed of a round hole and a square hole. The radius of the round hole is 18mm, and the distance between the center of the round hole and the center of the fixed hole 32 is 40mm.

[0029] In this embodiment, the base plate 2 is welded to the bottom end of the column 1. The base plate 2 has an opening 22, into which the bottom end of the column 1 is inserted. The welding of the base plate 2 and the column 1 at the opening 22 requires beveling, and the weld should be ground smooth after welding to avoid excessively high weld beads that could affect performance. The radius of the opening 22 is 17.5 mm, and the opening 22 communicates with the limiting hole 21. The limiting hole 21 is a strip-shaped hole or a waist-shaped hole, with a diameter or width of 11 mm. The distance between the center of its leftmost arc contour and the center of the opening 22 is 58 mm. The base plate 2 is a circular plate with a diameter of 135 mm and a thickness of 6 mm, made of Q235A material. The distance between the bottom surface of the base plate 2 and the bottom surface of the column 1 is 33 mm.

[0030] In this embodiment, the binding hole 51 is circular. The column 1 is cylindrical, with a height of 1021.5 mm between its bottom and top surfaces; its diameter is φ33.5 x 3.25 mm, and its material is Q235A. The slot 11 is 17 mm long and 8 mm high; the shape of the slot 11 matches the shape of the binding hole 51.

[0031] In practical applications, roll-on / roll-off ships, movable decks 5, and lashing holes 51 are existing technologies and will not be described in detail.

[0032] The principle of this embodiment is as follows: Before the railing is inserted into the binding hole 51 of the movable deck 5, the movable plate 3 and the pin 4 are lifted up a certain distance, and then the column 1 with the base plate 2 fixed is inserted into the binding hole 51. Then the entire railing is moved a certain distance along the direction of the slot 11, so that the edge of the binding hole 51 of the movable deck 5 is inserted into the slot 11 of the column 1, thereby restricting the railing from jumping up and down on the movable deck 5. Then the movable plate 3 and the pin 4 are lowered, so that the pin 4 is inserted into the limiting hole 21 of the base plate 2 and the binding hole 51 of the movable deck 5 in sequence, thereby restricting the railing from moving horizontally to the other side of the movable deck 5. In this way, the entire railing can be fixed to the movable deck 5, and vice versa.

[0033] The beneficial effects of this embodiment are as follows: This product can be easily and quickly installed and disassembled on the movable deck 5 of a roll-on / roll-off ship, it is plug-and-play and easy to operate; at the same time, since this product does not have the conventional deck protrusion railing base structure, it does not affect vehicle passage and improves loading and unloading efficiency. This utility model makes full use of the lashing holes 51 on the movable deck 5 of the vehicle for installing railings, which can effectively classify, isolate and guide the movable deck 5. Since this product does not require the use of a large number of bolts for fixing, it improves the efficiency of installation and disassembly, saves costs, and makes installation and disassembly simpler. The overall structure of this product is simple, easy to manufacture and process, low in cost, and has a wide range of applications.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that this embodiment provides a method for installing a portable railing for the movable deck of a roll-on / roll-off ship, the steps of which are as follows:

[0036] Step 1: Move the railing directly above the lashing hole 51 of the movable deck 5 so that the two are aligned, and lift the movable plate 3 and the pin 4 upwards along the post 1 a short distance.

[0037] Step 2: Insert the column 1 with the base plate 2 fixed to it into the binding hole 51 so that the bottom surface of the base plate 2 is in contact with and fits against the surface of the movable deck 5;

[0038] Step 3: Move the entire railing a certain distance along the direction of the slot 11 so that the edge of the binding hole 51 of the movable deck 5 (or the edge of the movable deck 5) is inserted into the slot 11 of the post 1.

[0039] Step 4: Lower the movable plate 3 and the pin 4 so that the pin 4 is inserted into the limiting hole 21 of the base plate 2 and the binding hole 51 of the movable deck 5 in sequence. At this time, the bottom side of the pin 4 is close to the edge of the binding hole 51.

[0040] The beneficial effects of this embodiment are as follows: through the above method and steps, the railing can be quickly installed on the movable deck 5 of the roll-on / roll-off ship, and disassembly is also very convenient.

[0041] Example 3

Simply pull out the fixing pin and rotate the upper post relative to the lower post to fold the railing. In normal operation, the operation is reversed: the upper post is rotated to the correct position relative to the lower post, and the fixing pin is reinserted into the locking hole for fixation. This further expands the application range of this product, making it more versatile. The railing does not need to be removed during use, saving time and effort, conserving railing storage space, and avoiding damage caused by disassembly and movement.
