Description

Technical Field

[0001] The invention relates to the technical field of releasing and guiding materials for a lifeboat and raft, in particular to a fast lifeboat and raft lifting and conveying mechanism. Background Art

[0002] A lifeboat / raft is a ship's lifesaving device. Depending on their structure, they can be categorized as rigid or inflatable. To facilitate rapid deployment in an emergency, significantly shortening deployment time and saving critical time for escape, a quick-release mechanism is required.

[0003] However, the lifeboat and raft releasing devices currently on the market adopt a fixed-position external structure design, which causes them to occupy a large external space and can only release and lift a single lifeboat and raft. In the later stage, it is also impossible to perform bottom loading while releasing, resulting in great limitations in use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the lifeboat and raft releasing devices currently on the market adopt a fixed-position external hanging structure design, which causes the external space to be very large and can only release and lift a single lifeboat and raft. In the later stage, it is also impossible to carry out bottom loading at the same time as the release, resulting in great limitations in use.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a fast lifeboat and raft lifting and feeding mechanism, including a bottom mounting seat fixedly mounted on the hull, an upper hanger movably mounted on the upper end of the bottom mounting seat, a lateral guide rail provided on the outer wall of the upper hanger, a movable lifting frame movably mounted inside the lateral guide rail, an electrically controlled lateral limit hanger movably mounted on the outer wall of the movable lifting frame, and a top crane for controlling the movable lifting frame mounted on the side wall of the upper hanger.

[0006] The lateral guide rail is designed as an embedded structure, and the opening position of the lateral guide rail is provided with an inwardly recessed shrinkage guide plate.

[0007] The movable lifting frame includes a split frame arranged inside the lateral guide rail, internal support guide wheels installed on both sides of the split frame, lateral connection frames installed at both ends of the split frame and an external assembly frame installed on the split frame.

[0008] The electrically controlled lateral limiting hanger comprises an arc-shaped installation frame movably installed on an external assembly frame and a lateral adjustment support rod for controlling the flipping of the arc-shaped installation frame.

[0009] An external thread tightening frame with telescopic notches on both sides is provided at the end of the lateral connection frame, and an internal thread tightening sleeve is sleeved on the outer side of the lateral connection frame.

[0010] An internal locking groove is provided on the inner wall of the external thread tightening frame.

[0011] The end portion of the hoisting cable of the top hoist is axially fixed with an end locking block that matches the internal locking groove.

[0012] The lateral connecting frame at one end of the split frame is locked and limited with the end locking block through the internal locking groove on the external thread tightening frame, and the other end of the split frame is locked and connected with the inner connecting steel cable through the external thread tightening frame.

[0013] A side guide groove matching the arc-shaped installation frame is provided on the outer side surface of the upper hanger.

[0014] An inner guide wheel set is movably installed inside the shrinking guide plate.

[0015] The beneficial effects of the present invention are:

[0016] (1) A fast lifeboat and raft lifting and feeding mechanism of the present invention is provided with a lateral guide rail on the outer wall of an upper hanger, and a movable lifting frame for lifting the lifeboat and raft is movably mounted inside the lateral guide rail. The top crane at the top of the upper hanger is used to control the movable lifting frame to rise and fall along the lateral guide rail, thereby achieving the purpose of fast material feeding;

[0017] (2) By using the lifting cable of the top crane to control the movable lifting frame, the movable lifting frame can be adjusted along irregular guide rails, which greatly improves its applicability;

[0018] (3) By using inner connecting steel cables to connect multiple movable lifting frames in series, the number of frames can be increased or decreased according to the size of the lifeboat and raft, which has a wider range of applications;

[0019] (4) The electrically controlled lateral limit bracket is assembled through the external assembly frame on the split frame, and the lifeboat and raft can be quickly assembled and released by flipping, which makes the operation more convenient;

[0020] (5) A side guide groove is provided on the upper hanger to match the arc-shaped installation frame, which can improve its limiting capacity and prevent the lifeboat and raft attached to the upper hanger from slipping during the lifting process, thus greatly improving safety;

[0021] (6) The external thread tightening frame at the end of the lateral connection frame is thread-locked by the internal thread tightening sleeve, thereby fixing the end of the top crane's cable and the inner connecting steel cable, making its loading and unloading more convenient and stable.

[0029] The lateral guide rail 3 is designed as an embedded structure, and the opening position of the lateral guide rail 3 is provided with an inwardly recessed shrinking guide plate 7.

[0030] The movable lifting frame 4 includes a split frame 41 arranged inside the lateral guide rail 3, internal support guide wheels 42 installed on both sides of the split frame 41, lateral connecting frames 43 installed at both ends of the split frame 41 and an external assembly frame 44 installed on the split frame 41.

[0031] The electrically controlled lateral limiting bracket 5 comprises an arc-shaped mounting frame 51 movably mounted on the external assembly frame 44 and a lateral adjustment strut 52 for controlling the flipping of the arc-shaped mounting frame 51 .

[0032] An external thread tightening frame 431 with telescopic notches on both sides is provided at the end of the lateral connection frame 43 , and an internal thread tightening sleeve 432 is sleeved on the outer side of the lateral connection frame 43 .

[0033] An internal locking groove 4311 is defined on the inner wall of the external thread tightening frame 431 .

[0034] The end of the hoisting cable 61 of the top hoist 6 is axially fixed with an end locking block 62 that matches the internal locking groove 4311.

[0035] In order to cooperate with the series connection and locking, the lateral connecting frame 43 at one end of the split frame 41 is locked and limited with the end locking block 62 through the internal locking groove 4311 on the external thread tightening frame 431, and the other end of the split frame 41 is locked and connected with the inner connecting steel cable 45 through the external thread tightening frame 431.
