Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment for ship unloading, in particular to a hoisting equipment for ship unloading. Background Art

[0002] Ship is a general term for various vessels. Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements. Ships are a man-made means of transportation that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that utilizes external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials.

[0003] A lifting device for ship unloading disclosed in the Chinese utility model patent application disclosure CN 215666727 U is useful for adjusting the lifting height. However, when applying lubricating oil to the lifting screw, due to the influence of friction when the lifting screw is running under heavy load, high pressure will be generated on the surface of the threaded rod, thereby accelerating the wear of parts. Therefore, lubricating oil needs to be applied to the lifting screw every period of time, and the device does not have the function of lubricating the lifting screw, resulting in the need to lubricate the lifting screw manually, which in turn affects the work efficiency. Therefore, there is a problem that the manual lubrication efficiency of the lifting screw is too slow, and when buffering the slide plate, although the device can buffer the slide plate through the buffer spring and the baffle, it is impossible to turn off the second motor after the slide plate hits the baffle to prevent the slide plate from continuing to move and causing damage to the buffer plate. Therefore, there is a problem that the second motor cannot be turned off after the slide plate hits the baffle. In summary, the utility model has the problems of too slow manual lubrication efficiency of the lifting screw and the inability to turn off the second motor after the slide plate hits the baffle.
