Abstract
The utility model relates to a lower hinged light-weight hydraulic watertight door for a ro-ro ship, consisting of a door body, a hinge, a support, sealing rubber strips, a hydrocylinder, a locking device and a hydrocylinder support, wherein the watertight door is matched with a vehicle slope ramp, the end of the slope ramp is arranged adjacent to the wall of a watertight chamber, and the hinge is arranged at the lower part of the door; when the door is opened, the door body is arranged on and integrated with a slope ramp so that vehicles can conveniently pass through; the door is opened or closed by utilizing the hydrocylinder, and the sealing rubber strips are arranged at the periphery of the door; and after being closed, the door is tightly locked by utilizing the locking device so as to ensure the watertightness. According to the gradient of the ramp and the hinge installation space, the distance from the wall of the watertight chamber to the end of the slope ramp is selected; the part of the slope ramp, which is adjacent to the wall of the watertight chamber, is partially downwards sunk, the sinking depth is equal to the thickness of the door body, and the length of the sunk range is equal to the length of the door body; and when the watertight door is opened, the door body can be smoothly arranged on and integrated with the slope ramp so that the vehicles can conveniently pass through.
Description
Technical field
The present invention relates to a kind of following hinge type light hydraulic watertight door that is used for roll-on-roll-off ship,, can make things convenient for vehicle to pass through, and guarantee that the water tightness of bulkhead meets the demands by this watertight door.
Background technology
Roll-on-roll-off ship vehicle hold watertight bulkhead is provided with watertight door, and when door was opened, vehicle can pass through thus, and when door was closed, this bulkhead was one watertight bulkhead, satisfies " standard " requirement for the cabin leakproofness.Watertight door commonly used at present has three kinds of forms: the upper hinge formula, limit hinge type and lateral slip formula, in actual use, the watertight door of these three kinds of forms all exists tangible deficiency: the water tightness requirement when closing in order to satisfy, upper hinge formula and limit hinge type all must be provided with threshold, hinder vehicle and pass through, and the watertight door of these two kinds of forms all occupies bigger space; Though it is less that lateral slip formula watertight door takes up space, must be provided with guide rail the upper and lower of door, lower guideway is equivalent to threshold, and in order to satisfy the requirement of water tightness, the size of aperture of door is restricted, and can not satisfy the demand that vehicle passes through sometimes.
Summary of the invention
In order to overcome the deficiency that existing watertight door exists on the roll-on-roll-off ship vehicle hold watertight bulkhead, the invention provides a kind of hinge type light hydraulic watertight door down, this door need not to be provided with threshold and guide rail, hull structure is not damaged, it is less to take up space, during unlatching, vehicle can pass through smoothly, when closing, can satisfy the requirement of water tightness, and the size of aperture of door can be chosen as required.
The technical solution adopted for the present invention to solve the technical problems is: watertight door and vehicle ramp road are equipped with, the end of ramp is arranged near the watertight bulkhead, hinge is arranged at the below of door, the door body was held on the ramp when door was opened, and form an integral body with it, make things convenient for vehicle to pass through; Utilize hydraulic ram to carry out the open and close of door, be provided with sealing rubber strip around the door, utilize latching device that it is locked after door is closed, guarantee its water tightness.
The technical program need adopt following 2 measures when implementing: one, and the end in vehicle ramp road is arranged near the watertight bulkhead, and the distance of itself and watertight bulkhead is chosen according to the gradient and the hinge installing space in ramp; Two, ramp is local recessed near the watertight bulkhead part, the recessed degree of depth equals the thickness of a body, and the length of recessed scope equals the length of a body, when watertight door is opened, this physical efficiency of door entirely is held on the ramp, and form an integral body with ramp, by above 2 measures, when guaranteeing to open, ramp is a smooth integral body, makes things convenient for vehicle pass-through.
The invention has the beneficial effects as follows: do not have threshold and guide rail, vehicle can pass through easily during unlatching, can guarantee watertight effectively when closing; Simultaneously, this mechanism takes up space less, hull structure is not damaged during installation.
Description of drawings
The present invention is further described below in conjunction with drawings and embodiments.
Fig. 1 is the lateral plan under the hinge type light hydraulic watertight door opening under the roll-on-roll-off ship.
Fig. 2 is the lateral plan under the hinge type light hydraulic watertight door closed condition under the roll-on-roll-off ship.
Fig. 3 is the front elevation under the hinge type light hydraulic watertight door closed condition under the roll-on-roll-off ship.
Among the figure: 1. a body, 2. hinge and bearing, 3. sealing rubber strip, 4. hydraulic ram, 5. latching device, 6. cylinder support, 7. deck, 8. ramp, 9. watertight bulkhead, 10. ramp recessed area
The specific embodiment
In Fig. 1, under opening, door body (1) is held on the ramp, hinge and bearing (2) are arranged in the below of door, sealing rubber strip (3) be installed on aperture of door on the bulkhead around, hydraulic ram (4) moves to range, makes a body (1) complete opening.The distance of watertight bulkhead and ramp end (diagram L) is chosen according to the gradient in ramp and the installing space of hinge and bearing (2), ramp is local recessed near the watertight bulkhead part, the recessed degree of depth equals the thickness of a body, the length of recessed scope equals the length of a body, when guaranteeing that a body (1) is held on the ramp and ramp form an integral body, make things convenient for vehicle pass-through.
Fig. 2 and shown in Figure 3 in, this door in off position down, hydraulic ram (4) shrinks, a door body (1) keeps airtight by sealing rubber strip (3) and latching device (5) with bulkhead.
