Abstract
Description
Technical Field
[0001] The invention relates to the field of immersed tube transportation, and in particular to an immersed tube air-saving cushion suspension device and a control method thereof. Background Art
[0002] At present, the transportation of pipe sections in large-scale projects adopts the method of building multiple sets of trolleys for joint transportation and laying out rail transportation in the dry dock. The trolley transportation and rail transportation must be kept at the same level during the transportation process to prevent excessive pressure at a single point from damaging the foundation and causing overall collapse and equipment damage. However, the manual arrangement of the trolley system and the rail system is complicated, and the ground foundation firmware needs to be laid in advance. The fixed path leads to limited maneuverability and difficulty in moving in complex environments. The transmission of the gravity of the pipe section to the ground is 1:1, and the high pressure on the dry dock ground is easy to damage the ground, limiting the size and weight of the pipe section. In addition, the corresponding trolleys and tracks for larger pipe sections must also be more powerful, further compressing the transportation space. The trolley control system needs to consider many complex aspects, involving the trolley's motion control, position control, communication system and energy management. The processing of data after acquisition requires a higher level of training for operators and is more troublesome in terms of human-computer interaction. The friction resistance of trolley transportation and rail transportation is large, the difficulty of fine control is high, and ground vibration affects the integrity of the pipe section.
