Description

TECHNICAL FIELD

[0001] The utility model belongs to shipbuilding technical field, especially relate to a buried type detachable handrail for engine room opening. BACKGROUND

[0002] There is an opening in the engine room of a ship, which is usually present on the passageway around the main engine. According to the conventional design, a designer will add a detachable ornamental steel plate at the opening, and a handrail is surrounded around it. These handrails mainly isolate the outside world when the opening is opened, and play a good protective role for the workers. Because the opening is located on the passageway of the engine room, the ship owner often requires these handrails to be detachable to ensure that the passageway has sufficient space for people to walk. The detachable handrails need to be burned on the deck, and the handrail body is fastened by bolts. When the opening is closed, the handrail body can be simply removed. However, there are two problems according to this method. The legs of the handrail burned on the deck still hinder walking. The ship is shaking when sailing, which can easily cause unnecessary harm. When the opening needs to be opened or closed tightly, the workers need to constantly fasten or remove the handrail body, which increases the workload of the crew and reduces the loading and unloading efficiency.

[0021] The utility model is further described below in combination with the drawings and specific embodiments.

[0022] As Figures 1-6 shown, a kind of embedded detachable rail for cabin opening, including multiple rail body 1 and multiple fixed components, multiple the fixed components are distributed on the lower end surface of deck 7 at the cabin opening 6 side, deck opening is set at the deck 7 located directly above the fixed component, and one end of multiple the rail body 1 is inserted into deck opening and is connected with fixed component.

[0023] It can be understood that the fixed component is arranged on the lower end surface of deck 7, and the rail body 1 is connected with the fixed component by extending from the deck 7 to the lower end surface of deck 7, thereby forming the embedded structure design of the rail, which avoids forming the protrusion on the upper end surface of deck 7 that hinders passing.

[0024] Further, the fixed component is a pre-buried clamping groove 2, which is a cylindrical structure with a closed end and an open end, the open end is arranged opposite to the deck opening, and one end of the rail body 1 extends to the bottom of the pre-buried clamping groove 2.

[0025] It can be understood that the fixed end of the rail body 1 can be directly inserted into the pre-buried clamping groove 2, so that the fixing and dismounting operation of the rail body 1 is simple.

[0026] The pre-buried clamping groove 2 can be provided with only one layer of sleeve pipe, or two layers of sleeve pipes, or one layer of sleeve pipe and one double-wall pipe. In order to ensure the connection stability of the rail body 1 and the connection stability of the pre-buried clamping groove 2 at the same time, in some embodiments, the pre-buried clamping groove 2 includes a bottom plate 21, a double-wall pipe 22 and a sleeve pipe 23 are fixedly arranged on the bottom plate 21 along the same center axis, the sleeve pipe 23 is sleeved outside the double-wall pipe 22, one end of the double-wall pipe 22 and the sleeve pipe 23 away from the bottom plate 21 is fixedly connected with the lower end surface of the deck 7, the rail body 1 is a hollow pipe, and one end of the rail body 1 is inserted between the two layers of pipe walls of the double-wall pipe 22.

[0027] It can be understood that the pre-buried clamping groove 2 is provided with the sleeve pipe 23 and the double-wall pipe 22 at the same time, the diameter of the annular cavity in the double-wall pipe 22 is relatively small compared with the inner diameter of the rail body 1, which ensures the stability of the rail body 1 in use, and the sleeve pipe 23 with larger diameter ensures the stability of the connection between the pre-buried clamping groove 2 and the deck 7, so that the pre-buried clamping groove 2 will not be separated from the deck 7 due to the shaking of the rail body 1.

[0028] Further, the sleeve pipe 23 is a seamless steel pipe.

[0029] Further, the longitudinal section of the railing body 1 is in inverted U shape, the free ends of the two side arms of the railing body 1 are inserted between the two layers of the pipe wall of the double-wall pipe 22; the guard chain lock 4 is arranged oppositely on the two side arms of the railing body 1, and the two railing bodies 1 arranged oppositely are connected by the guard chain 5 connected to the guard chain lock 4.

[0030] Since oil and water may drip during the loading of the ship, the holes in the deck 7 are prone to cause accumulation and erosion of the parts, and the water-blocking part added on the side arm of the railing can avoid such problems as much as possible. In some embodiments, to solve the technical problem, the deck opening water-blocking part is arranged at the free end of the two side walls of the railing body 1, so as to prevent oil or water from entering the embedded clamping groove 2 during hoisting to cause corrosion and pollution.

[0031] In some embodiments, the deck opening water-blocking part is a water-blocking cap 3, the water-blocking cap 3 comprises a top plate 31, a seat sleeve 32 arranged with the same center axis is fixed on the lower end surface of the top plate 31, a through hole arranged with the same center axis is formed on the top plate 31, and the two side arms of the railing body 1 are respectively provided with a water-blocking cap 3 and are fixedly connected with the water-blocking cap 3. The height of the water-blocking cap 3 is determined by the embedded depth of the two side walls of the railing body 1, and the stability of the railing body 1 during use can be ensured.

[0032] It can be understood that the water-blocking assembly is arranged in the form of a water-blocking cap 3 and is sleeved on the side arm of the railing, which can prevent oil or water from entering the embedded clamping groove 2 during hoisting to cause corrosion and pollution, and on the other hand, it can increase the stable support of the railing body 1 and reduce the obvious shaking of the railing body 1.

[0033] It can be understood that the water-blocking assembly is arranged in the form of a water-blocking cap 3 and is sleeved on the side arm of the railing, which can prevent oil or water from entering the embedded clamping groove 2 during hoisting to cause corrosion and pollution, and on the other hand, it can increase the stable support of the railing body 1 and reduce the obvious shaking of the railing body 1.
