DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the present utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 3 As shown, the utility model discloses a landing craft hanging door safety protection device, including a handrail device 1 welded on the hanging door 2, and the handrail device 1 is symmetrically arranged with two. Specifically, the handrail device 1 includes an L-shaped round tube guardrail mechanism and a connecting piece connected between the round tube guardrail mechanism and the hanging door 2. The handrail device 1 is firmly connected to the hanging door 2 through the round tube guardrail mechanism and the connecting piece structure. The structure is stable, ensuring the safety and reliability of long-term use. It should also be noted that the handrail device 1 is close to the end of the hanging door 2 for contacting the island and reef. Because the crew is prone to violent ups and downs and front and back shaking due to the impact of waves and the uneven ground at the moment of landing on the island and reef, the hanging door 2 is prone to cause the crew to fall. Therefore, the handrail device 1 is arranged at this position, which can protect the personnel when going up and down the hanging door 2. The personnel can rely on the handrail device 1 to buffer the up and down waves and the front and back impacts, thereby enhancing the safety of the operation, especially when carrying heavy objects (such as batteries, lamps). The effect is obvious. In addition, the handrail device 1 forms a unified style with the upper deck of the hull, and does not affect the overall beauty of the ship.

[0024] In addition, further, the round tube guardrail mechanism is retractably arranged on the connecting piece, and a fixing mechanism for fixing the round tube guardrail mechanism and the connecting piece is provided on the round tube guardrail mechanism, so that the height of the round tube guardrail mechanism can be adjusted at any time according to needs, and it can be fixed by the fixing mechanism after the adjustment is completed. For example, when transporting relatively large objects, the round tube guardrail mechanism can be slightly lowered, so that it will not cause obstruction while providing necessary support. In normal use, it can be adjusted according to the general height of the crew, preferably about 1.2 meters, flush with the human waist, so as to provide a gripping point and support for personnel when going up and down the hanging door 2.

[0025] Specifically, the circular tube guardrail mechanism includes a middle branch pipe 3, a longitudinal round rod 4 fixed on the upper side of the side wall of the middle branch pipe 3, a transverse round rod 5 fixed on the upper side of the side wall of the middle branch pipe 3 and perpendicular to the longitudinal round rod 4, a first branch pipe 6 fixed on the longitudinal round rod 4, and a second branch pipe 7 fixed on the transverse round rod 5, wherein the transverse round rod 5 is close to one end of the hanging door 2 for contacting the island reef, and a passage for people to pass through is formed between the longitudinal round rods 4 of the two handrail devices 1. Then, the connecting part specifically includes a connecting circular tube 8 welded to the hanging door 2, and one connecting circular tube 8 is correspondingly arranged on the lower side of the middle branch pipe 3, the first branch pipe 6 and the second branch pipe 7. The middle branch pipe 3, the first branch pipe 6 and the second branch pipe 7 are respectively slidably sleeved on the corresponding connecting circular tubes 8, so that the up and down height can be adjusted.

[0026] like Figure 3 As shown, the fixing mechanism includes a screw rod 9 located inside the middle branch pipe 3, and the screw rod 9 is rotatably connected to the upper end of the middle branch pipe 3. The upper end of the screw rod 9 penetrates the middle branch pipe 3 and is provided with a prismatic socket 10. The prismatic socket 10 can be used for the insertion of a hand wheel or a handle, so as to facilitate the rotation of the screw rod 9. The upper side of the inner part of the connecting circular tube 8 located on the lower side of the middle branch pipe 3 is fixedly connected with a nut seat 11, and the screw rod 9 is threadedly engaged with the nut seat 11. Therefore, when the screw rod 9 is rotated, the middle branch pipe 3 can be driven to move up and down, that is, the circular tube guardrail mechanism can be moved up and down. It should be noted that the circular tube guardrail mechanism is preferably made of a light but sufficiently strong and corrosion-resistant material, such as aluminum alloy, so that the screw rod 9 can easily drive the entire circular tube guardrail mechanism.

[0027] In addition, the fixing mechanism also includes a clamping screw 12, which is threadedly engaged with one on the side walls of the first branch pipe 6 and the second branch pipe 7. The clamping screw 12 is used to clamp on the connecting circular tube 8 on the inner side of the first branch pipe 6 and the second branch pipe 7. When adjusting the height of the circular tube guardrail mechanism, the clamping screw 12 is loosened.

[0028] In the utility model, the circular tube guardrail mechanism also includes a first round rod 13 fixedly connected between the first branch pipe 6 and the middle branch pipe 3, and a second round rod 14 fixedly connected between the second branch pipe 7 and the middle branch pipe 3. The first round rod 13 and the second round rod 14 can further enhance the protection effect and strengthen the structure of the circular tube guardrail mechanism. In addition, the end of the longitudinal round rod 4 away from the middle branch pipe 3 is integrally formed with a bent support rod 15 that is bent in an arc and fixedly connected to the first branch pipe 6. The arc-shaped structure of the bent support rod 15 can enhance the safety performance of the utility model.

[0029] In the present invention, the longitudinal round rod 4 and the transverse round rod 5 are both covered with an elastic sheath 16, which can provide a comfortable grip, prevent scratches or damage to the goods when carrying them, and reduce the risk of hard collisions.

[0030] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
