Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Embodiment one
As shown in Figure 1, a kind of immersed tube tunnel stern of the utility model end protector, comprise main frame 1, the top of described main frame 1 is provided with the hanger 3 for connecting crane gear, conveniently this immersed tube tunnel stern end protector is sling or is put down.Be connected with some connecting rods between the frame of described main frame 1, connecting rod comprise the montant that vertically arranges and be symmetricly set on these montant both sides, be obliquely installed brace, make primary frame 1 supporting & stablizing, structure is firm.The frame and connecting rod of described main frame 1 are interval with some elastic components 2, and all elastic components 2 are all arranged on the same side of main frame 1.
Be connected with starting device by main frame 1 by hanger 3 during use, starting device is installed aboard ship, main frame 1 is down to immersed tube tube coupling stern end, makes elastic component 2 relative with tube coupling stern end, simultaneously with starting device tension, makes main frame 1 keep standing.At shallow water area, main frame 1 top is exposed, and can play warning function, avoids dredging operation ship near tube coupling stern end; Even if operation ship distance tube coupling stern end is comparatively near, encounter main frame 1; Due to the existence of elastic component 2, main frame 1 and the collision of tube coupling stern end can be cushioned, protect tube coupling to seal up a door and steel end housing.
Preferably, main frame 1 is provided with some inlet openings, and current can freely be flow to by inlet opening or flow out, and the setting of inlet opening reduces main frame and slinging and entering the resistance of water process, and convenient operation, ensures the stability of this protector in water simultaneously.
Embodiment two
As shown in Figure 2, the present embodiment is substantially identical with embodiment one, and difference is, is connected with auxiliary frame 4 in one end of main frame 1, and auxiliary frame 4 is vertical with main frame 1 to be arranged, and auxiliary frame 4 and described elastic component 2 are connected to the same side of described main frame 1; Auxiliary frame 4 is similar to main frame 1 structure, and the side of auxiliary frame 4 is also connected with elastic component 2, and described elastic component 2 is positioned at inside the angle of auxiliary frame 4 and main frame 1, and elastic component 2 is preferably D type rubber fender.
Because main frame 1 and auxiliary frame 4 form a L-type structure, after this protector is placed into seabed, can stand voluntarily, can fix without the need to boom hoisting is auxiliary.Auxiliary frame 4 can also prevent boats and ships or desilting equipment from meeting with tube coupling stern end from the side, and protected effect is better.Auxiliary frame 4 is also provided with hanger 3, and after lifting, this protector is more stable, can not swing voluntarily, just with lifting and place.For strengthening main frame 1 and the bonding strength of auxiliary frame 4, be connected to bracing piece 5 between.Preferably, bracing piece 5 is arranged on the side that auxiliary frame 4 does not arrange elastic component 2, avoids bracing piece 5 to encounter tube coupling stern end.
Preferably, main frame 1 and/or auxiliary frame 4 are provided with some inlet openings, and current can freely be flow to by inlet opening or flow out, and the setting of inlet opening reduces this protector and slinging and entering the resistance of water process, convenient operation, ensures the stability of this protector in water simultaneously.
Embodiment three
As shown in Figure 3, the present embodiment is substantially identical with embodiment two, difference is, an auxiliary frame 4 has been symmetrical arranged at the other end of main frame 1, two auxiliary frames 4 are all positioned at the side that main frame 1 arranges elastic component 2, and the elastic component 2 of three frameworks is all arranged on the inner side of " spectacle " structure that three surrounds.This structure is stood stable; hanger 3 is evenly distributed; Hoisting Security, convenience; general protection can be carried out from three directions to tube coupling stern end simultaneously; even if collide; D type rubber also can play cushioning effect, thoroughly gets rid of the possibility that tube coupling stern end is sealed up a door or steel end housing is broken by boats and ships or desilting equipment.
As can be seen from the above embodiments, the utility model by arranging a framework at tube coupling stern end, and arranges the mode of elastic component 2 on framework, achieves and to seal up a door to tube coupling stern end or the protection of steel end housing, avoid it to be broken by dredging operation boats and ships or desilting equipment; The setting of auxiliary frame 4, makes this protector more easily keep standing, assists without the need to boom hoisting; Bracing piece 5 is arranged on outside auxiliary frame 4, while playing booster action, it also avoid the possibility that bracing piece 5 collides with tube coupling stern end; Main frame 1 and auxiliary frame 4 arrange inlet opening, facilitates seawater to pass in and out, this protector can be reduced and putting into water or the resistance from water taking-up process, reduce seawater to its active force, ensure the stability of structure, also reduce operation resistance simultaneously.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
