[0001] This utility model relates to the technical field of pilot ladder railing gates, specifically, to a pilot ladder railing gate. Background Technology

[0002] According to IMOA.1045(27), ships of 500 gross tonnage and above that can employ pilots during navigation should be equipped with pilot boarding and disembarking devices. The most commonly used boarding and disembarking device is the pilot ladder. To ensure the safe, convenient and unobstructed boarding and disembarking of pilots, the boarding and disembarking passage between the pilot ladder and the ship's deck should be equipped with handrails for pilot use. The height of the handrails should be higher than the height of the railings to meet the regulatory requirements. At the same time, there should be eye plates to fix the ladder and safety ropes. In order to reduce the friction damage of the pilot ladder at the edge of the deck, the boarding and disembarking passage should be equipped with appropriate anti-abrasion devices. Finally, a qualified boarding and disembarking passage should also be equipped with appropriate handrail rope positioning devices to reduce the entanglement or swinging of handrail ropes caused by excessive wind and waves.

[0003] In the existing technology, the railings and boarding / disembarking passages on both sides of a ship require the combined use of various equipment, which is complex in structure and inconvenient to operate. Therefore, this utility model proposes a pilot ladder railing gate. Utility Model Content

[0004] This utility model proposes a pilot ladder railing gate, which solves the problem in related technologies that the railings on both sides of the ship and the boarding and disembarking passages require the use of various equipment in combination, resulting in complex structures and inconvenient operation.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figures 1-4 As shown, this embodiment proposes a pilot ladder railing gate, including a regular railing 1, a railing gate 2, a pilot ladder 5, a handrail rope 51, and a handrail base 6. Two sleeves 3 are installed on the regular railing 1. One side of the railing gate 2 is movably installed on one side of the sleeve 3 via a hinge 21, and the other side is fixed to the other side of the sleeve 3 via a pin 22. Handrail steel pipes 4 are slidably connected inside the sleeves 3. The bottom end of each handrail steel pipe 4 is slidably provided with an extension tube 61. The extension tubes 61 are fixedly installed in the handrail base 6. The extension tubes 61 are also provided with a pre-positioning locking piece 7 for positioning and locking the handrail steel pipes 4.

[0033] The pre-positioning locking component 7 includes a locking outer cylinder 71, which is fixedly installed on the extension outer tube 61. A pin positioning tube 72 is slidably connected inside the locking outer cylinder 71. A latch 73 is fixedly sleeved at one end of the pin positioning tube 72 inside the locking outer cylinder 71. A recessed groove 74 is provided on the handrail steel pipe 4. A spring 75 is fixedly connected between the inner wall of the locking outer cylinder 71 and the latch 73. A pin hole 62 is provided on the side wall of the recessed groove 74, extending to the inner walls of the handrail steel pipe 4 and the extension outer tube 61. The design of the pin positioning tube 72 not only prevents the pin 22 from accidentally being inserted after the railing gate 2 is opened. The latch 73 is missing, and can be used with the pin 22 to secure the connection between the handrail steel pipe 4 and the extension outer pipe 61; the end of the latch 73 facing the concave groove 74 is a curved structure, and the inner wall of the concave groove 74 is an arc-shaped curved structure. After use, when the railing gate 2 is reset and the height of the handrail steel pipe 4 is hidden, the pin 22 is first pulled out from the pin positioning tube 72. The handrail steel pipe 4 can be rotated 180 degrees in the opposite direction, and the latch 73 can be pushed out by the inside of the concave groove 74. The latch 73 can be separated from the handrail steel pipe 4, and the handrail steel pipe 4 can be pressed down to be basically level with the height of the surrounding ordinary railing 1.

[0034] In this embodiment, when not in use, the bottom end of the handrail steel pipe 4 is inserted into the interior of the extended outer pipe 61 and hidden in the handrail base 6. The height of the handrail steel pipe 4 is basically the same as the height of the ordinary railing 1. The railing gate 2 can be used with the ordinary railing 1 to form an ordinary railing 1 without occupying deck space.

[0035] In use, remove the pin 22 on one side of the railing gate 2 to open the railing gate 2, opening the pilot passage established on the side of the deck facing the pilot ladder 5. At the same time, rotate the handrail steel pipe 4 180 degrees and lift it up. The top of the handrail steel pipe 4 is lifted out of the sleeve 3. During the lifting of the handrail steel pipe 4, after the concave groove 74 and the latch 73 are aligned, the spring 75 in the stored state can push the latch 73 into the concave groove 74, limiting the height of the handrail steel pipe 4, and making the handrail steel pipe 4 establish a locking relationship with the extension outer tube 61 through the pre-positioning locking member 7. Then, insert the pin 22 into the pin positioning tube 72 and pass through the pin hole 62 to further fix the height of the handrail steel pipe 4, so that it can be used as a handrail for the pilot.

[0036] Example 2

[0037] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the ordinary railing 1 is a square structure formed by three horizontal bars and two posts. The horizontal bars and posts are ordinary steel pipes, and the steel pipe model is consistent with that of the handrail steel pipe 4. The distance between the horizontal bars meets the standard requirements for the distance between the railing horizontal bars. The top of each handrail steel pipe 4 is fixed with a ring 41 for threading the handrail rope 51, which is used to fix the handrail rope 51. When put into use, the two handrail ropes 51 provided with the pilot ladder 5 are threaded through the ring 41 and hung on the outer plate, which can effectively reduce the swaying and entanglement of the handrail rope 51 caused by wind and waves. An eye ring 24 is fixed to the railing gate 2, and an eye ring 24 is fixed to the ordinary railing 1. 4. The matching fixing hook 23 can be inserted into the eye ring 24 to fix the railing gate 2 after it is opened, preventing the railing gate 2 from swinging uncontrollably. The wear-resistant pipe 8 is fixed between the two handrail bases 6. When in use, the pilot ladder 5 is laid on the wear-resistant pipe 8. The height of the steel pipe is 150mm from the deck. This wear-resistant pipe 8 can be regarded as part of the railing gate 2, so that the bottom horizontal bar of the railing gate is no more than 230mm from the deck surface, which meets the requirements of the regulations for marine railings. More importantly, the wear-resistant pipe 8 can be used as a wear-resistant material for the pilot ladder 5. When the pilot ladder 5 is on the outer plate, it can be placed on the wear-resistant pipe 8 to avoid the pilot ladder 5 being damaged by friction at the edge of the outer plate.

[0038] As described above, the pilot ladder railing gate of this utility model integrates the pilot's handrail, safety rope positioning device, and abrasion-resistant material into one unit, making it simple to manufacture and easy to operate. When not in use, the pilot ladder railing gate can be regarded as an ordinary railing and does not occupy deck space. When put into use, simply remove the fixing pin on one side of the railing gate, rotate the two handrail steel pipes with eyelets at the top 180 degrees, and then lift them. During the lifting process, the latches will automatically engage with the handrail steel pipes. The removed fixing pin can be inserted into the latches to connect and fix the handrail steel pipes and the extended outer pipe, thus becoming a convenient and safe pilot boarding and disembarking passage.

[0039] 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.
