Description

Technical Field

[0001] The invention belongs to the technical field of cranes, and in particular relates to a guide rail structure of a ship crane. Background Art

[0002] Ship crane is an important mechanical equipment installed on ships for loading, unloading and handling cargo. It is mainly used for cargo transportation and transfer between ships. The guide rail of the crane is a series of products specially used for the running track of the crane. It is mainly made of high-strength steel. This kind of guide rail has the characteristics of high precision, high rigidity and high durability, and can withstand various loads and stresses during the operation of the crane. However, when actually lifting the cargo, the lifting point and the landing point of the cargo will not be the center of the crane. Therefore, when the mobile component is running on the crane, the gravity levels on both ends of the guide frame are not the same, especially when the ship is sailing. At this time, the crane base is not completely in a horizontal state, and the offset force is more obvious. The traditional guide rail structure adopts hard connection, and the connection strength on both sides of the horizontal position cannot be adjusted.
