Description

Technical Field

[0001] The invention relates to the technical field of elevator linkage of large ships or other three-dimensional transfer systems, in particular to a sliding watertight door flap linkage mechanism. Background Art

[0002] Watertight doors are installed at the hatches of each floor station of the elevator. When they are fully closed, they play the role of isolation and watertightness, and have a barrier and protective function in the event of accidents such as fire and flooding. When they are fully opened, they can open up the hatch space to facilitate the transfer of equipment and materials.

[0003] The existing design and use mode at home and abroad is that the watertight door is driven and controlled by hydraulic equipment or motors, which has the following main shortcomings:

[0004] 1. The existing watertight doors designed and used are all small-sized or low-water-pressure watertight doors. When the watertight door structure is larger or the water pressure is higher, the structure of the conventional frameless watertight door often cannot meet the watertight requirements:

[0005] 2. In order to meet the tightness requirements, a watertight door structure with a sealing strip installed on the door frame is required, so grooves need to be cut on the deck. In order to ensure the passability of vehicles, flaps need to be used to cover the grooves on the deck.

[0006] 3. To ensure the overall operating efficiency, the opening and closing time of the watertight door is short. The existing driving and control of the flap adopts hydraulic cylinders or motors, which are driven by travel switches. This method will increase costs and affect the system reliability index, and even affect the system operating efficiency;

[0007] In order to ensure the overall operating efficiency, the opening and closing time of the watertight door is relatively short. Under the existing design mode, the opening and closing action of the watertight door usually does not have a deceleration process. It is easy to have a large impact when closing or opening to the full extent, which is not conducive to the normal operation of the equipment. Summary of the invention

[0008] In view of the above-mentioned problems existing in the prior art, an embodiment of the present invention provides a sliding watertight door flap linkage mechanism, which can reduce costs, improve equipment reliability and operating efficiency while meeting existing usage functions, and has the characteristics of simple structure, high reliability and efficient operation.

[0009] The embodiment of the present invention provides a sliding watertight door flap linkage mechanism, comprising:

[0010] The watertight door is installed in the cabin and moves in the guide rail through the drive of the driving cylinder to realize the opening and closing of the landing door;

[0011] A gear rack mechanism, comprising a gear and a rack that are meshed with each other, wherein the rack is mounted on the upper portion of the door body of the watertight door;

[0012] A reversing device, which is fixed on the top of the cabin, and the gear is arranged on the input shaft of the reversing device;

[0013] A sprocket mechanism, one end of which is drivingly connected to the output shaft of the reversing device;

[0014] A flap, on which a rotating shaft is provided, and the rotating shaft is drivingly connected to the other end of the sprocket mechanism;

[0015] The flap is linked with the opening and closing of the watertight door. After the watertight door is opened, the flap is laid flat and covers the deck groove corresponding to the door body. After the watertight door is closed, the flap is lifted and set at a set angle with the door body.

[0016] In some embodiments of the present invention, when the watertight door is opened by the drive cylinder, the door body drives the gear to rotate through the rack, and the gear drives the input shaft of the reversing device to rotate. After the reversing of the reversing device, the reversing device drives the sprocket mechanism through the output shaft, and the sprocket mechanism drives the rotating shaft of the flap to rotate, thereby driving the flap to flip and fall. After the watertight door is fully opened, the flap is flatly covered on the deck groove corresponding to the door body to make the deck flat and easy to pass.

[0017] In some embodiments of the present invention, when the watertight door is closed by the drive cylinder, the door body drives the gear to rotate through the rack, and the gear drives the input shaft of the reversing device to rotate. After the reversing of the reversing device, the reversing device drives the sprocket mechanism through the output shaft, and drives the rotating shaft of the flap to rotate through the sprocket mechanism, thereby driving the flap to flip and lift. After the watertight door is completely closed, the flap is lifted, and the plane where the flap body is located is set at a set angle with the plane where the door body is located, and the set angle is in the range of 0 degrees to 10 degrees.

[0018] In some embodiments of the present invention, the watertight door comprises a door body, a door frame, a sealing ring, and a locking mechanism, wherein:

[0019] The door frame is welded to the hull structure, the sealing ring is installed on the door frame, and the driving cylinder drives the door body to move along the guide rail direction;

[0020] The locking assembly is installed on the door frame and the door body. When the watertight door is closed, the door body squeezes the sealing strip to ensure the watertight performance of the watertight door.

[0021] In some embodiments of the present invention, the reversing device is fixed to the inner top of the cabin by structural welding, and the reversing device is provided with bevel gears that are meshed with each other to achieve the change of transmission direction, thereby achieving the transmission of the force of the input shaft of the reversing device through the gears to the sprocket mechanism through the output shaft.

[0022] In some embodiments of the present invention, the flap mechanism is fixed to the cabin deck via a mounting seat, one end of the flap's rotating shaft connected to the sprocket mechanism is provided with a connecting gear meshing with the sprocket mechanism, and the flap's plate body is fixedly connected to the rotating shaft via a bracket.

[0023] In some embodiments of the present invention, when the watertight door is closed, the plate body of the flap is vertically arranged.

[0024] Compared with the prior art, the beneficial effects of the sliding watertight door flap linkage mechanism provided by the embodiment of the present invention are: it adopts a structural scheme consisting of a door frame, a sealing strip, a door body, a driving cylinder, a guide rail, a gear rack mechanism, a reversing device, a sprocket mechanism and a flap, and compared with the traditional watertight door, it has the characteristics of simple equipment structure, good watertightness, low manufacturing and maintenance costs, and high reliability; further, it can also realize the linkage between the horizontal sliding watertight door and the hatch flap, that is, the sliding opening and closing of the watertight door and the flipping of the flap are carried out simultaneously, thereby improving the overall operating efficiency of the elevator.
