[0031] Please refer to Figures 1-3 , this embodiment provides a manhole protection structure 100 for a ship, which is installed on the manhole 210 of the upper deck 200 of the ship. The manhole protection structure 100 includes a handrail 10 and a base 20. The handrail 10 includes a crossbar 11 and vertical bars 12 connected to both sides of the crossbar 11.
[0032] The base 20 is installed on the manhole 210 on the deck 200. The base 20 includes a first clamping plate 21, a second clamping plate 23 and a connecting plate 22. The first clamping plate 21 and the second clamping plate 23 are arranged at intervals and are both fixedly connected to the connecting plate 22. The first clamping plate 21 is provided with a mounting hole 211 and a fixing hole 212. The mounting hole 211 is arranged close to the connecting plate 22. The fixing hole 212 is arranged far from the connecting plate 22. The vertical bar 12 is used to be inserted into the mounting hole 211 to fix the handrail 10. The fixing hole 212 is used to pass through a fixing screw 24 to install the base 20 on the deck 200.
[0033] It can be understood that the base 20 in this embodiment is a fixed fixture. Specifically, the base 20 is used to clamp the edge of the manhole 210 of the deck 200. That is to say, the edge position of the manhole 210 of the deck 200 is located between the first clamping plate 21 and the second clamping plate 23. In this embodiment, the distance between the first clamping plate 21 and the second clamping plate 23 is fixed. A manhole ring 220 is provided at the position of the manhole 210 of the deck 200. The manhole ring 220 protrudes from the surface of the deck 200. The distance between the first clamping plate 21 and the second clamping plate 23 is greater than the sum of the thicknesses of the deck 200 and the manhole ring 220, so that the base 20 can be completely clamped into the edge of the manhole 210 of the deck 200. After the base 20 is clamped into the edge of the manhole 210 of the deck 200, the fixing screw 24 is passed through the fixing hole 212 to abut against the surface of the deck 200, thereby fixing the base 20 on the deck 200.
[0034] When the deck 200 is in daily use, the armrest 10 can be pulled out of the base 20 so that there are no obstacles above the plane of the deck 200, avoiding the armrest 10 protruding from the plane of the deck 200 and blocking walking. When it is necessary to pass through the manhole 210, the armrest 10 can be inserted into the base 20. When personnel pass through the manhole 210, they can hold the armrest 10 to prevent falling. It should be noted that the manhole 210 of the deck 200 in this embodiment is opened only when it is necessary to pass through, and is closed by the manhole cover during normal use. When the manhole 210 is opened, an armrest 10 needs to be installed above, which can not only prompt personnel above to take a detour, but also prevent personnel entering and leaving the manhole 210 from slipping and falling, improving safety performance.
[0035] Furthermore, a limit block is provided on the vertical rod 12. The limit block is used to abut against the first clamping plate 21. It can be understood that when the armrest 10 is inserted into the base 20, the setting of the limit block facilitates prompting that the installation is in place.
[0036] Specifically, the limit block includes a first limit ring 121 and a second limit ring 122. The distance between the first limit ring 121 and the second limit ring 122 is equal to the thickness of the first clamping plate 21. It can be understood that the first limit ring 121 and the second limit ring 122 have a certain elasticity. When the armrest 10 is gradually inserted downward into the base 20, the second limit ring 122 is squeezed into the installation hole 211 of the first clamping plate 21. When the second limit ring 122 pops out of the installation hole 211, the first limit ring 121 and the second limit ring 122 are respectively located on both sides of the first clamping plate 21, thereby fixing the vertical rod 12 on the base 20.
[0037] Still further, a limit hole 231 is provided on the side of the second clamping plate 23 facing the first clamping plate 21. The limit hole 231 is used to cooperate with the vertical rod 12. It can be understood that after the vertical rod 12 is inserted between the first clamping plate 21 and the second clamping plate 23, it is then inserted into the limit hole 231 of the second clamping plate 23 to further fix the position of the armrest 10.
[0038] In this embodiment, the height of the first limiting ring 121 is greater than that of the second limiting ring 122. It can be understood that it is more difficult for the first limiting ring 121 to be squeezed into the mounting hole 211 relative to the second limiting ring 122. When the second limiting ring 122 moves downward and pops out of the mounting hole 211, the pressure of pressing the armrest 10 downward is not sufficient to cause the first limiting ring 121 to be squeezed into the mounting hole 211, thereby indicating that the armrest 10 is installed in place and preventing relative movement between the armrest 10 and the base 20.
[0039] In order to prevent the fixing screw 24 from contacting and wearing the deck 200, in this embodiment, the base 20 further includes an anti-wear pad 25. The anti-wear pad 25 is arranged between the fixing screw 24 and the deck 200. It can be understood that the anti-wear pad 25 avoids direct contact between the fixing screw 24 and the deck 200, and at the same time increases the friction between the fixing screw 24 and the deck 200, preventing relative movement between the fixing screw 24 and the deck 200 and preventing wear.
[0040] It can be understood that in this embodiment, the number of bases 20 is two, which are respectively connected to the two vertical rods 12 of the armrest 10. The base 20 is fixed to the deck 200 by fixing screws 24. The position of the base 20 can loosen the fixing screws 24, thereby adjusting the relative position between the base 20 and the deck 200, and thus adjusting the relative position between the armrest 10 and the manhole 210.
[0041] In order to prevent the vertical rod 12 and the mounting hole 211 from being misaligned due to the position error of the base 20 when the armrest 10 is installed on the base 20, in this embodiment, the cross bar 11 is a telescopic rod. It can be understood that setting the cross bar 11 as a telescopic structure enables the vertical rods 12 at both ends to be installed in the mounting holes 211 at any position, improving the adaptability of the armrest 10. It can be understood that the cross bar 11 in this embodiment is a straight bar.
[0042] Furthermore, the vertical rod 12 in this embodiment is cylindrical, and the mounting hole 211 is a circular hole. It can be understood that when the angle of the base 20 in the plane of the deck 200 changes, the vertical rod 12 can also be inserted into the mounting hole 211.
[0043] In order to adjust the height of the armrest 10, in this embodiment, the vertical rod 12 is also a telescopic rod. An adjusting screw is further arranged on the vertical rod 12 for fixing the length of the vertical rod 12. In addition, setting the vertical rod 12 as a telescopic rod can shorten the vertical rod 12 when the armrest 10 does not need to be installed, reducing the space occupied by the armrest 10.
[0044] Furthermore, a first positioning member is also provided on the base 20. A second positioning member cooperating with the first positioning member is also provided on the deck 200. It can be understood that the first positioning member and the second positioning member are used to position the depth of the base 20 inserted into the edge of the manhole 210 of the deck 200.
[0045] Specifically, in this embodiment, the first positioning member is a positioning post 232. The positioning post 232 is provided on the second clamping plate 23 and faces the first clamping plate 21. The second positioning member is a positioning groove. The positioning groove is opened below the deck 200. It can be understood that the shape of the positioning groove is the same as that of the manhole 210, and the distance between the positioning groove and the edge of the manhole 210 is equal everywhere.
[0046] The beneficial effects of the manhole protection structure 100 of the ship in this embodiment are:
[0047] The manhole protection structure 100 of the present utility model includes a handrail 10 and a base 20. The handrail 10 includes a cross bar 11 and vertical bars 12 connected to both sides of the cross bar 11. The base 20 is installed on the manhole 210 of the deck 200. The base 20 includes a first clamping plate 21, a second clamping plate 23 and a connecting plate 22. The first clamping plate 21 and the second clamping plate 23 are arranged at intervals and are both fixedly connected to the connecting plate 22. The first clamping plate 21 is provided with a mounting hole 211 and a fixing hole 212. The mounting hole 211 is arranged close to the connecting plate 22. The fixing hole 212 is arranged away from the connecting plate 22. The vertical bar 12 is used to be inserted into the mounting hole 211 to fix the handrail 10. The fixing hole 212 is used to pass through a fixing screw 24 to install the base 20 on the deck 200. The manhole protection structure 100 fixes the base 20 on the edge of the manhole 210 of the deck 200 and installs the handrail 10 on the base 20 in an inserted manner. When the deck 200 is in daily use, the handrail 10 can be pulled out of the base 20 to avoid the handrail 10 protruding from the plane of the deck 200 and blocking walking. When it is necessary to pass through the manhole 210, the handrail 10 can be inserted into the base 20. When personnel pass through the manhole 210, they can hold the handrail 10 to prevent falling. The manhole protection structure 100 of the present utility model can realize the quick disassembly of the handrail 10 and the manhole 210 of the deck 200, remove the handrail 10 during the daily use of the deck 200 to avoid obstruction, and install the handrail 10 when it is necessary to pass through the manhole 210 to prevent personnel from falling, improving the safety performance.
[0048] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
