Technical Field
[0001] The utility model relates to a crane pipe, in particular to a disassembly device which is convenient for replacing the crane pipe when loading it onto a vehicle. Background Art
[0002] Hoist pipes, also known as liquid loading arms, are specialized equipment used in the petrochemical industry for liquid loading and unloading. These flexible devices utilize rotating joints, connected to rigid pipes and elbows, to transfer liquids between trains, tank trucks, and trestle storage and transportation pipelines. These devices replace conventional hose connections and offer high safety, flexibility, and a long service life. Hoist pipes primarily consist of fixed, rotating, operating, and balancing mechanisms, as well as oil piping.
[0003] During long-term use, the sealing surface and bearing parts between the column and the rotary joint will gradually wear out, especially under high load and high frequency use, which will accelerate the wear of the sealing surface and bearing parts. The wear of the sealing surface may cause the leakage of hazardous chemicals, causing fire, explosion or poisoning accidents. The wear of the bearing parts may cause sudden failure of the equipment, causing mechanical accidents and endangering the safety of the operator. The rotary joint is often fixed on the column, which makes it impossible to quickly remove the rotary joint from the column, thereby affecting the replacement efficiency of the crane pipe.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0011] Furthermore, in order to facilitate the movement of the moving block, one end of the moving block extends outside the disassembly box and is fixedly connected to the moving plate.
[0012] Furthermore, in order to increase the sealing between the column and the rotary joint, a protruding piece is fixedly connected to the top end of the column, and a groove is provided on the bottom end of the rotary joint, and the groove matches the protruding piece.
[0013] Furthermore, in order to increase the sealing performance between the groove and the protruding piece, a sealing ring is provided between the protruding piece and the groove, and the sealing ring is fixedly connected in the groove.
