Description

Technical Field

[0001] The invention relates to the technical field of hoisting, and in particular to cargo hoisting, lifting and unloading equipment for ships. Background Art

[0002] The ship will be equipped with a lifting device for lifting cargo. The lifting device is equipped with a lifting arm, which is generally composed of a main lifting arm and multiple auxiliary lifting arms. The lifting arm can be extended and retracted to change the length of the entire lifting arm, which is convenient for lifting cargo. When the length of the entire lifting arm becomes longer, its entire force center of gravity is on the main lifting arm. The existing lifting equipment has a too simple supporting mechanism for the main lifting arm, and it is not possible to achieve multi-point support for it, which is not conducive to the long-term and stable use of the lifting equipment. In particular, when lifting work is carried out on board, the working environment is more complicated, and the lifting arm cannot retract the supporting mechanism in the non-working state to reduce the space occupied by the lifting equipment. Furthermore, in order to lift safely, weights are generally added to the rear end of the main lifting arm for balance, which is more troublesome to operate and there is a risk of the weight falling off.

[0014] Compared with the prior art, the invention has the following advantages: 1. A retractable auxiliary support mechanism is provided on the hoisting machine. When the hoisting machine is in a non-working state, the retractable auxiliary support mechanism is in a retracted state, reducing the space occupied by the entire hoisting equipment. When the hoisting machine is in a working state, it can be unfolded, thereby providing multi-point support for the main boom on the hoisting machine, fully ensuring the stability of the main boom during the hoisting process, enhancing its own strength, and facilitating its long-term and stable use.

[0015] 2. When the main boom is working, the hydraulic rod drives the bearing movable platform to move. As the bearing movable platform moves, it will drive the driving connecting plate to move upward, and then under the action of the driving connecting plate, it will drive the movable support platform to move upward. As the movable support platform moves upward, the driving matching plate will contact with the main boom. In this way, as the movable support platform moves upward, under the restriction of the main boom, the distance between the driving matching plate and the movable support platform will become smaller, and then the first auxiliary support plate and the second auxiliary support plate will be driven to move away from the movable support platform. At the same time, the first auxiliary support plate and the second auxiliary support plate will contact with the main boom to provide auxiliary support to it and ensure its stability during work.

[0016] 3. In addition, when the bearing movable platform is moving, the connecting plate frame will be driven downward by the driving connecting rod. As the distance between the closed piston plate and the movable plug plate increases, a larger negative pressure will be formed in the negative pressure inner cavity, and then the negative pressure will generate a downward suction force on the closed piston plate, and then generate a larger downward suction force on the main boom, so that it can maintain a balanced state during the lifting process, without the need to load it, which is very convenient.

[0038] When the hoisting machine 1 is working, the hydraulic rod 15 is extended to drive the bearing movable platform 2 to move toward the outside of the inner groove 14. As the bearing movable platform 2 moves, the movable support hinge rod 251 will push the driving connecting plate 3 upward to make it move upward. As the driving connecting plate 3 moves upward, it will drive the movable support platform 4 to move upward as well. The upward movement of the movable support platform 4 will make the driving matching plate 5 contact with the main boom 11.

In addition, while the bearing movable platform 2 is moving, it will also drive the connecting frame 27 to move in the direction of the hoisting machine platform 1, and then, under the action of the driving connecting rod 29, it will push the connecting plate frame 8 downward. As the connecting plate frame 8 moves downward, it will drive the movable plug plate 82 to move downward, so that the distance between the movable plug plate 82 and the closed piston plate 112 becomes larger, and then negative pressure can be generated in the negative pressure inner cavity 19. In this way, under the action of the negative pressure, a downward suction force is generated on the main boom 11, and under the action of the suction force, the balance of the main boom 11 during the hoisting process can be guaranteed to ensure its safe work, and counterweight operation is required.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
