For prefabricated pipeline construction, in order to ensure the installation accuracy on site, after the prefabrication of the inlet and outlet pipelines of the equipment is completed, it is necessary to perform pre-assembly in the workshop.
[0003] In order to achieve a high degree of restoration of the workshop and construction site scenarios, we have invented a flange simulation device for the inlet and outlet of large-scale equipment. The relative positions of the four flanges can be adjusted horizontally, vertically, front-back, and high-low to adapt to different types of equipment.
[0004] An automatic control system, a simulation avoidance mechanical method, and a moving track are organically combined to form a complete flange simulation device system. Through the PLC, the actions of each part are coordinated uniformly to realize the automatic adjustment, avoidance, and movement of the flange simulation device.
[0005] During the flange pre-assembly process, first, the flange is adjusted to the initial position through the automatic control system, then, according to the surrounding environment and the situation of obstacles, the simulation avoidance mechanism is started to make the flange simulation device avoid obstacles, and finally, the flange simulation device is moved to the position accurately docked with the inlet and outlet pipelines of the equipment through the moving track.
[0006] During the whole process, high-precision sensors and control algorithms are used to ensure the adjustment accuracy of the flange position and angle. At the same time, through the precise control of simulation avoidance and the moving track, the docking accuracy between the flange simulation device and the inlet and outlet pipelines of the equipment is improved to meet the requirements of actual operation.
