Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1 to Figure 4 As shown, a unilaterally driven horizontal hinged non-threshold watertight landing door, including top double-ear hinge 4, hydraulic latch 2, landing door body 1, bottom pressing wedge 9, support block 8, guide block 6, watertight rubber 3. Driving oil cylinder 7, beading 5, etc.

[0017] The watertight rubber 3 is arranged on the inner side of the top of the landing door body 1, the bead 5 is arranged on the bulkhead, and the bottom pressing wedge seat 9) is arranged on the bottom plate.

[0018] The landing door adopts the top two-ear hinge 4-opening type. The landing door body 1 is floatingly connected with the bulkhead through the top double-ear hinge 4, and forms an upward-opening landing door. The landing door body 1 is connected with the bulkhead through the driving cylinder 7 arranged on one side, and is u...

Abstract

The invention relates to a unilaterally driven horizontal hinge type non-threshold watertight landing gate. The unilaterally driven horizontal hinge type non-threshold watertight landing gate comprises a landing gate body, a top two-lug hinge, a drive oil cylinder, watertight rubber arranged on the inner side of the top of the landing gate body, a batten arranged on the bin wall, a bottom pressing wedge base arranged on a bin bottom board. The landing gate body is connected with the bin wall in a floating mode through the top two-lug hinge, and an upturned landing gate is formed. The landing gate body is connected with the bin wall through the drive oil cylinder arranged on the single side so that the landing gate can be opened. Sealing of the top of the landing gate is achieved through linkage of two connecting points on hinge bodies on the two sides of the top two-lug hinge, and the landing gate is opened or closed stably through rigid connection between the hinge bodies on the two sides of the top two-lug hinge. The unilaterally driven horizontal hinge type non-threshold watertight landing gate can be applied to watertight landing gates for ship lifters, and can improve the airtightness and safety of a whole passageway and a whole bin.

Description

technical field [0001] The invention relates to a horizontally moving landing door for a ship lift, in particular to a watertight landing door without a threshold. Background technique [0002] At present, the vertical transfer of goods in the cabins of ships on the water surface is mainly realized by marine elevators and lifting platforms, and at the same time, forklifts are allowed to enter; one or two horizontally moving landing doors with their own door frames are installed on each deck, mainly for forklifts. Cargo loading and unloading, protection of the lifting passage, and prevention of personnel falling; however, some ships require that the landing door be directly arranged on the watertight bulkhead of the internal compartment below the main deck, and there is no need to set a supporting door frame at all, and it is required to withstand no less than 10.5 Meters of watertight load to ensure the watertight state of the channel; at the same time, in order to facilitat...
