Description

Technical Field

[0001] The utility model relates to the technical field of ship cranes, in particular to a ship hydraulic crane. Background Art

[0002] Marine hydraulic cranes are important equipment on ships. They are fully hydraulically driven and are specifically used for lifting and moving cargo. The main components of marine hydraulic cranes include the boom, tower and movement. The movement provides power, and the tower can rotate 360 degrees on the large base plate. The lifting and lowering of the boom is controlled by the contraction of the wire rope connected to the tower and the boom, thereby achieving the lifting and moving of cargo. This design allows the hydraulic crane to accurately locate the target position and ensure the safe lifting of cargo.

[0003] After searching, a maintenance device for ship locks was proposed according to the Chinese utility model application number CN202322157508.X. The invention content records that "the utility model solves the problem that when hoisting objects, the existing hoisting equipment uses bolts and nuts to lock the objects on the hooks to prevent the objects from being suspended in the air and shaking, causing the objects to fall off the hooks of the hoisting equipment. However, the bolts and nuts will wear out after long-term use, resulting in slippage and loose connections. At the same time, the bolts and nuts are time-consuming and inconvenient to operate to lock the objects, which will affect the staff."

[0004] Among them, the inspection device for the ship lock requires one hand to hold the handle and push the connecting rod backward when hanging an item on the hook, so that the fixing rod is disengaged from the inside of the fixing groove and remains stationary, and then use the other hand to hang the item on the hook. After hanging, the handle is released to insert the fixing rod into the inside of the fixing groove. When hanging heavy items, it is time-consuming and laborious to hang the items on the hook with only one hand, which affects the use. Therefore, a ship hydraulic crane is proposed to solve the above problems. Utility Model Content

[0007] The locking mechanism includes a spring, which is fixedly connected to the inner wall of the warehouse body, and a moving block is fixedly installed on the side of the spring away from the inner wall of the warehouse body, and a locking rod is fixedly installed on the side of the moving block away from the spring, and the side of the locking rod away from the moving block passes through the warehouse body and extends to the interior of the hook, and a moving rod is fixedly installed on the moving block that passes through and extends to the outside of the warehouse body, and a moving hole matching the moving rod is opened inside the warehouse body, and a limiting hole is opened inside the warehouse body, and the limiting hole is connected to the moving hole, and a moving plate is provided on the moving rod.

[0008] Furthermore, a rotating shaft is rotatably mounted on the hydraulic crane body via a bearing, and the connecting column is fixedly connected to the inside of the rotating shaft.

[0009] Furthermore, a through hole is opened inside the warehouse body, and the through hole matches the locking rod.

[0010] Furthermore, a locking groove is provided inside the hook, and the locking groove matches the locking rod.

[0011] Furthermore, the cross section of the locking rod is rectangular, and the cross section of the limiting hole is hook-shaped.

[0012] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0013] The marine hydraulic crane is provided with a locking mechanism, which not only locks the hook, but also allows the user to hang heavier objects on the hook with both hands, thus saving time and effort and making it convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
