Description

Technical Field

[0001] The invention relates to the technical field of ship cranes provided with auxiliary stabilizing components, in particular to a ship crane provided with auxiliary stabilizing components. Background Art

[0002] Marine cranes, also known as ship cranes, are a type of lifting machinery used specifically on various ships for operations such as cargo handling, equipment installation, and hull repair. Usually, these cranes are installed above the deck of the ship.

[0003] There are many types of ship cranes, including deck cranes, mast cranes, cable cranes, rotatable cranes, etc. They each have their own characteristics. For example, deck cranes are flexible to operate and highly efficient; mast cranes are ship cranes that combine deck cranes and bulk cranes; cable cranes are suitable for lifting larger cargoes, such as steel cables, components and other items; rotatable cranes can rotate in horizontal and vertical directions to achieve multi-directional lifting and unloading.

[0004] However, the existing ship cranes have complex structures and are inconvenient to operate. During use, they have poor stability, and the booms and hooks are usually of fixed lengths and cannot be adjusted according to the position of the cargo. Therefore, we provide a ship crane with an auxiliary stabilization component to solve the above problems. Summary of the invention

The second hinge axis provided at the bottom of the arm body is hinged to the rear end of the angle control cylinder. The second hinge axis provided at the middle of the bottom of the first telescopic groove is hinged to the front end of the push rod of the angle control cylinder. The angle control cylinder can drive the push rod to lift the boom and change the angle between the boom and the arm body.

[0010] Preferably, one end of the auxiliary stabilizing rod is hinged on the third hinge shaft on both sides of the bottom of the arm body, the other end of the auxiliary stabilizing rod is provided with a second telescopic groove, the telescopic auxiliary stabilizing rod is inserted in the second telescopic groove, and the other end of the telescopic auxiliary stabilizing rod is hinged to the third hinge shaft arranged on the outside of the moving block.

Then the winding assembly controls the winding drum to rotate, unwinds the steel wire rope wound on the winding drum, so that the steel wire rope drives the hook to descend, so that the hook hooks the cargo, and then the winding assembly controls the winding drum to reverse, so that the steel wire rope lifts the cargo through the hook, and then the middle part of the bottom of the arm body and the middle part of the bottom of the boom are hinged through the second hinge shaft to control the angle of the cylinder, which pushes the first telescopic slot through the push rod to lift the first telescopic slot, change the angle between the first telescopic slot and the arm body, and Lifting, the first telescopic slot simultaneously lifts the cargo hooked by the hook at the bottom front end of the telescopic boom, and the first telescopic slot simultaneously lifts, the telescopic auxiliary stabilizing bar synchronously slides in the second telescopic slot opened in the middle of the auxiliary stabilizing bar when the first telescopic slot is lifted. When the first telescopic slot is fixed, the electric push rod arranged on the inner side of the support plate moves by pushing the tooth plate to make the teeth arranged on the inner side of the tooth plate insert into the tooth groove arranged on one side of the telescopic auxiliary stabilizing bar, thereby limiting the telescopic auxiliary stabilizing bar and preventing the telescopic auxiliary stabilizing bar from sliding. At this time, the auxiliary stabilizing bar and the telescopic auxiliary stabilizing bar begin to provide auxiliary stabilizing support to the first telescopic slot and prevent the first telescopic slot from being lifted unstable; further, the limit plates on both sides of the telescopic auxiliary stabilizing bar are inserted into the limit grooves opened on both sides of the second telescopic slot of the auxiliary stabilizing bar to limit the telescopic auxiliary stabilizing bar and prevent the telescopic auxiliary stabilizing bar from rotating in the second telescopic slot, resulting in the inability to align the tooth groove and the tooth plate.
