DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0023] like Figures 1 to 4 As shown, a preferred embodiment of the utility model provides a marine lifting device, which includes a support frame, a rotating handle 2, a rotating shaft 3, a rotating sleeve 4 and a spring 5, wherein the rotating handle 2, the rotating shaft 3, the rotating sleeve 4 and the spring 5 are all arranged on the support frame, the rotating handle 2 is connected to the rotating sleeve 4 through the rotating shaft 3 and is used to drive the rotating sleeve 4 to rotate, one end of the spring 5 is fixedly connected to the support frame, the other end of the spring 5 is fixedly connected to the rotating sleeve 4 and is used to drive the rotating sleeve 4 to rotate and reset, and a rope for hanging objects is wound around the outer periphery of the rotating sleeve 4.

[0024] When it is necessary to transport small workpieces, the support frame is fixed on the marine equipment, the workpiece is hung on the rope wrapped around the rotating sleeve 4, and the rotating shaft 3 is driven to rotate by turning the handle 2, so as to realize the lifting and lowering action of the workpiece. The operation is simple, and there is no need to use large-scale lifting equipment, which saves costs; and the support frame can be fixed at any place on the ship, and the use scene is not restricted, which is convenient to use and saves manpower and material resources; in addition, when the device is used to descend an object, the rotation of the rotating sleeve 4 drives the outer ring of the spring 5 to rotate, so that part of the kinetic energy of the object during the descent is converted into the potential energy of the spring 5. When the object is lowered into place and disengaged from the lifting device, the potential energy of the spring 5 is released, driving the rotating sleeve 4 to rotate in the opposite direction, so that the rope on the rotating sleeve 4 is automatically recovered, which is simple and convenient; by adopting the utility model, small workpieces can be transported at any position on the ship, which is not restricted by the scene and is convenient to use.

[0025] It is understandable that when the device is used to raise an object, the clockwork spring 5 can be removed to avoid interference with the rising action of the object.

[0026] Exemplarily, the support frame includes a left support frame 11 and a right support frame 12, the left support frame 11 is provided with an adjustment block 13, the adjustment block 13 is laterally adjustable on the left support frame 11, one end of the clockwork 5 is fixedly connected to the left support frame 11, the rotating shaft 3 is rotatably connected to the right support frame 12, and the rotating handle 2 is arranged on one end of the right support frame 12 away from the left support frame 11. Therefore, when in use, the distance between the left support frame 11 and the right support frame 12 can be adjusted according to actual needs, thereby expanding the scope of application of the device and facilitating use.

[0027] Exemplarily, a first bearing 14 is provided on the adjusting block 13, the inner ring of the first bearing 14 is fixedly connected to the adjusting block 13, the outer ring of the first bearing 14 is fixedly connected to the rotating sleeve 4, one end of the mainspring 5 is fixedly connected to the inner ring of the first bearing 14, and the other end of the mainspring 5 is fixedly connected to the outer ring of the first bearing 14.

[0029] It should also be noted that in order to prevent the rotating sleeve 4 from rotating too fast, an anti-falling device can be provided inside the rotating sleeve 4. The structure of the anti-falling device is the same as the inertial locking wheel structure in the automobile seat belt in the prior art, such as the Chinese patent application, publication number: CN107323411B; when the rotating sleeve 4 rotates too fast in a certain direction, due to the centrifugal effect, the internal gears of the anti-falling device will engage and lock, causing the rotating sleeve 4 to stop rotating, thereby preventing the object from falling rapidly and accidentally.

[0030] Exemplarily, in order to facilitate the fixation of the support frame, the lower ends of the left support frame 11 and the right support frame 12 are provided with a clamping assembly 6, and the clamping assembly 6 includes a connecting member 61, an adjusting bolt 62 and a gasket 63. The connecting member 61 is fixed to the left support frame 11 or the right support frame 12, and a threaded hole is provided on the connecting member 61. The adjusting bolt 62 passes through the threaded hole and is connected to the gasket 63.

[0031] Exemplarily, the rotating handle 2 is provided with a handle 21. When the lifting device performs an object lowering operation, a rope can be connected to the outside of the handle 21, and the speed of the object lowering can be controlled by pulling and releasing the rope.

[0032] Exemplarily, the rotating handle 2 is provided with a crank 22. When the lifting device performs an object lifting operation, the handle 21 is rotated by using the crank 22, which is convenient and labor-saving.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
