Description

Technical Field

[0001] The utility model relates to the technical field of crane pipes, in particular to a special loading and unloading crane pipe. Background Art

[0002] Train unloading cranes have been widely used in major oil depots and chemical plants. They have developed from the earliest ordinary single manual unloading cranes to various forms of unloading cranes with superimposed drive devices. That is, the drive device drives the inner arm to make horizontal rotational movement relative to the column, drives the outer arm to make horizontal rotational movement relative to the inner arm, drives the outer arm to swing up and down relative to the inner arm, and drives the sealing cap to rise and fall. Common types of drive actuators include oil cylinders, oil motors, air cylinders and air motors. The three-dimensional movement function of the crane is realized by driving the drive actuators to meet the requirements of changing loading positions of tank trucks of different heights when they are randomly docked.

[0003] The on-site working conditions of the train unloading crane pipe are much larger in spatial dimensions than those of the automobile closed loading and unloading crane pipe, especially in terms of height distance. The root cause is that the external dimensions of the train are much larger than those of the automobile tank truck, and therefore the corresponding crane pipe structure dimensions of the train are also much larger. This means that when planning and arranging the closed crane pipe unloading of the train, if there is a rain shelter or other building structure above the tank truck, sufficient height space must be left. However, in some oil depots and chemical plants, there is not enough space left, and it is difficult to insert the pump head on the crane pipe into the tank mouth of the train tank truck. Therefore, this application proposes a special loading and unloading crane pipe to solve the above-mentioned problem that the crane pipe pump head is difficult to insert into the tank mouth of the train tank truck.
