Description

Technical Field

[0001] The utility model belongs to the technical field of railings, and particularly relates to a roll-on railing for a launch ship. Background Art

[0002] When a launch ship is traveling at high speed or encountering a dangerous situation, crew members and passengers are easily injured or even fall into the water by accident. Therefore, railings are provided around the launch ship to provide a safe standing and walking area for the crew, prevent people from falling from the ship's side, and ensure personnel safety. Patent No.: CN215155446U proposes a ship railing lengthening device, which includes a lengthened railing. A fixing member is connected to the end of the lengthened railing. The fixing member includes a fixing plate fixed to the ship's railing. A vertical plate is perpendicularly fixed to the surface of the fixing plate. A rotating shaft parallel to the fixing plate is perpendicularly fixed in the middle of the vertical plate. The rotating shaft passes through the end of the lengthened railing and is rotatably connected to the lengthened railing. The lengthened railing can be turned 180° away from the fixing plate around the rotating shaft. A positioning groove is recessed downward at the top of the vertical plate. A positioning pin embedded in the positioning groove is fixed on the lengthened railing. A longitudinal sliding hole for the rotating shaft to slide is provided on the side wall of the lengthened railing. The lengthened railing realizes the separation of the positioning pin and the positioning groove through the longitudinal sliding hole. The ship railing lengthening device of the utility model can be selected and installed at places where the height of the guardrail needs to be increased according to actual needs. The railing lengthening device has a simple structure, convenient height adjustment operation, and is firmly fixed to the original guardrail after fixing, with high safety.

[0003] However, there are some problems in the prior art: In the prior art, the railing on the large open deck is welded to the deck by means of a backing plate, and then the rod is welded to the backing plate to achieve the function of personnel protection. For traditional ships, this installation method has no problem, but for the large open deck of a large ship, due to the wide application of SPMT now, when transporting large ship parts, SPMT is directly used to roll them onto the ship. As a result, before each ship loading, the welded railings on the ship's deck need to be cut off, which not only involves huge workload, repeated cutting and welding resetting, but also causes damage to the ship's base material and ship painting, wasting labor, effort and money. Therefore, we propose a roll-on railing for a launch ship. Summary of the Utility Model

Detailed Description of the Embodiments

[0025] To further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0026] As Figures 1 to 6 shown, a roll-on / roll-off railing for a launch ship provided by an embodiment of the present utility model includes a bottom plate 1. The bottom plate 1 is rectangular and made of stainless steel. The main function of the bottom plate 1 is to connect the base 2 and fix the base 2 on the main deck of the ship.

[0027] The base 2 is fixedly connected to the bottom plate 1. The base 2 is connected to the bottom plate 1 by welding. The base 2 can be directly welded to the bottom of the main deck through the bottom plate 1, or directly embedded into the main deck, so that the base 2 will not form an obstacle to the roll-on / roll-off operation on the deck surface.

[0028] A fixing rod 3 is detachably connected to the base 2. The fixing rod 3 is a cylindrical long rod made of stainless steel. The upper end of the base 2 is open. The base 2 is cylindrical, and the opening is also cylindrical and matches the size and shape of the fixing rod 3. The fixing rod 3 can be inserted into the base 2. A hole is opened on the inner wall of the base 2, and a bolt 9 is arranged in the hole. A through hole is opened at the lower end of the fixing rod 3, and the bolt 9 is arranged through the through hole.

[0029] When installing the fixing rod 3, insert the fixing rod 3 into the base 2, then pass the bolt 9 through the hole on the base 2 and the through hole on the fixing rod 3, and then tighten the bolt 9 to fix the fixing rod 3 in the base 2. When the fixing rod 3 needs to be disassembled, remove the bolt 9 and then pull out the fixing rod 3.

[0030] A first cross bar 4 is fixedly connected to the fixed rod 3. The first cross bar 4 is cylindrical and made of stainless steel. The first cross bar 4 has the function of blocking and intercepting. A movable rod 5 is slidably connected to the fixed rod 3. A sliding groove is provided in the fixed rod 3. The movable rod 5 is slidably connected in the sliding groove. A hexagonal hole is provided on the inner wall of the sliding groove of the fixed rod 3. A latch 10 is inserted in the hexagonal hole. An avoidance hole is provided on the movable rod 5, and the latch 10 passes through the avoidance hole.

[0031] A threaded hole is provided at one end of the latch 10, in which a locking screw 11 is arranged. The locking screw 11 is used to fix the latch 10 to ensure that after the movable rod 5 is inserted into the fixed rod 3, when the hull shakes violently, the latch 10 will not be detached from the movable rod 5 and the fixed rod 3, causing the railing to tip over or fall off, causing cargo or crew members to fall into the water, causing losses and personal injuries.

[0032] When installing the movable rod 5, insert the movable rod 5 into the sliding groove of the fixed rod 3, then align the avoidance hole on the movable rod 5 with the hexagonal hole on the fixed rod 3, then pass the pin 10 through the avoidance hole on the movable rod 5 and the hexagonal hole on the fixed rod 3, and then screw the locking screw 11 into the threaded hole on the pin 10. When the movable rod 5 needs to be removed, unscrew the locking screw 11, and then take out the pin 10, and the movable rod 5 can be pulled out from the sliding groove of the fixed rod 3.

[0033] The movable rod 5 is detachably connected to a second cross bar 6 , which has the same function as the first cross bar 4 , namely, blocking and intercepting. Slideways are provided on both sides of the second cross bar 6 , in which a connecting rod 12 is slidably connected, and the connecting rod 12 is used to connect the movable rod 5 .

[0034] One end of the connecting rod 12 is fixedly connected with a limiting plate 13. The limiting plate 13 is used to limit the sliding of the connecting rod 12, so that the connecting rod 12 will not break away from the second cross bar 6 and cause the loss of the connecting rod 12. The other end of the connecting rod 12 is threadedly connected to the movable rod 5, which is convenient for removing the second cross bar 6, so that the movable rod 5 can be retracted into the fixed rod 3.

[0035] Rotating the connecting rod 12 can make the connecting rod 12 disengage from the movable rod 5, and then make the second cross bar 6 disengage from the movable rod 5. After that, unscrew the locking screw 11 and then pull out the bolt 10, the movable rod 5 can be retracted into the chute of the fixed rod 3. Then insert the bolt 10 again to fix the movable rod 5 on the fixed rod 3, and the height of the railing can be adjusted. When handling some goods, it is not necessary to disassemble all the railings, saving manpower and time.

[0036] The upper end of the base 2 is rotatably connected with a cylinder cover 7. The upper end of the base 2 is fixedly connected with a fixing block 14. The fixing block 14 is fixedly connected with a rotating shaft 15. One side of the cylinder cover 7 is fixedly connected with a connecting block 16. The connecting block 16 is rotatably connected to the rotating shaft 15.

[0037] After the railing is disassembled from the base 2, by rotating the cylinder cover 7, the connecting block 16 can be driven to rotate on the rotating shaft 15, so that the cylinder cover 7 can rotate relative to the base 2, and then the cylinder cover 7 can block the opening above the base 2, so as to avoid sundries falling into the base 2 during cargo handling, causing the channel in the base 2 to be blocked, making it impossible to install the railing subsequently, and it is necessary to consume manpower and time to clean the base 2. When the railing needs to be installed, just remove the cylinder cover 7.

[0038] A drain port 8 is opened at the lower end of the base 2. The drain port 8 is at the bottommost end of the base 2. The drain port 8 is semi-circular. Its main function is to drain the seawater entering the base 2 to avoid the base 2 being immersed in seawater for a long time, causing rust and corrosion of the base 2, affecting its use and even causing safety accidents.

[0039] A fixing column 17 is fixedly connected to the middle of the bottom end of the bottom plate 1. The fixing column 17 is cylindrical and made of stainless steel material. The fixing column 17 extends into the deck, thus firmly fixing the base 2 on the deck to avoid the railing from tipping over.

[0040] The working principle of the present utility model is as follows:

[0041] In the present utility model, the railing is divided into two parts. One part is the detachable part, which includes a fixed rod 3, a movable rod 5, a second cross bar 6, etc. It can be detached from the base 2 to avoid hindering the handling of goods on the deck.
