Propulsion control device of tunnel boring machine for 3D printing a tunnel

A propulsion control device of a 3D printing-based tunnel boring machine, comprising two propulsion control modules, which are connected front to back and each of which comprises tunnel support assemblies, a propulsion control assembly and a barrel body, wherein:

• each propulsion control assembly comprises a propulsion controller and a propulsion sliding sleeve, the propulsion sliding sleeves are arranged on outer surfaces of the barrel bodies, and a length of the propulsion sliding sleeves is less than that of the barrel bodies;
• each propulsion controller comprises a propulsion hydraulic cylinder and a propulsion hydraulic cylinder extending end, the propulsion hydraulic cylinders and the propulsion hydraulic cylinder extending ends are respectively connected to the barrel bodies and the propulsion sliding sleeves in a hinged manner, and the barrel bodies and the propulsion sliding sleeves relatively move with expansion and contraction of the propulsion hydraulic cylinder extending ends;
• and
• a plurality of tunnel support assemblies are arranged on an outer side of each propulsion sliding sleeve in a surrounding manner, and each tunnel support assembly, having a closed state, comprises a support arm hydraulic controller having two ends, steering regulators and support plates, the two ends of each support arm hydraulic controller are connected to the steering regulators;
• each steering regulator comprises a steering regulation slide bar, a steering regulation slide rail and a steering regulation support rod, the steering regulation slide bars are slidably connected to the steering regulation slide rails, the steering regulation slide bars are connected to the ends of the support arm hydraulic controllers, and the steering regulation support rods are connected to the support plates in a hinged manner;
• and when both ends of the support arm hydraulic controllers expand and contract, the steering regulation slide bars slide in the steering regulation slide rails, and the steering regulation support rods rotate to change a lifting state of the support plates.
