Description

Technical Field

[0001] The utility model relates to the technical field of crane pipes, in particular to a truss type crane pipe. Background Art

[0002] With the development of the domestic petrochemical industry, when loading and unloading various toxic and hazardous liquids, workers must climb onto the tank trucks to perform the docking operations of the crane pipes, which will inevitably cause harm to the workers' health. The truss crane pipe includes a crane pipe body, a lifting and moving component, a lateral moving component, a longitudinal moving component and a guide pipe. It realizes movement in different directions in an automated way to complete the loading task, reduce the labor intensity of on-site personnel, reduce the accident rate, and reduce the participation of personnel in the loading process.

[0003] For example, the utility model with application number 202121585056.X discloses a truss-type crane pipe. Due to the arrangement of the longitudinal walking trolley, the transverse walking trolley, the vertically arranged telescopic vertical pipe, the winch and the pull rope, the longitudinal walking trolley and the transverse walking trolley can be operated through the electric control cabinet, so that the telescopic vertical pipe can move to a suitable position in the horizontal plane, and its lower end and the sealing cap are directly opposite to the docking port opened on the top of the tank truck to be loaded and unloaded below. The winch can then be operated through the electric control cabinet to drive the telescopic vertical pipe to descend, so that the lower end of the telescopic vertical pipe extends from the docking port on the top of the tank truck into the tank truck, and the sealing cap is also sealed on the docking port on the top of the tank truck, thereby completing the docking and allowing loading and unloading.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of truss crane pipe docks with the tank truck by moving the crane pipe's position with longitudinal and transverse trolleys. However, the stability of this type of truss crane pipe is poor. Simply using transverse and longitudinal traveling trolleys to move on the truss may result in problems such as instability during movement, which increases the difficulty of docking the bottom crane pipe with the tank truck.

[0006] Therefore, a truss crane pipe is designed to optimize the above problems. Utility Model Content
