Description

Technical Field

[0001] The utility model relates to the technical field of shaft construction equipment, in particular to a double-layer support shoe supporting device for a shaft expansion boring machine. Background Art

[0002] When the shaft shield machine is drilling for rock breaking, it needs to apply a certain pressure to the drill bit, that is, the rock breaking drilling pressure, and at the same time drive the drill bit to rotate with a certain torque. The two work together to transfer the rock breaking energy to the rock breaking roller to achieve efficient rock breaking and finally form the required well wall. The shaft shield machine power head relies on the thrust provided by the support propulsion system to apply drilling pressure and torque to the drill bit. At the same time, the support structure provides counter-torque to keep the shaft shield running stably; and after the shaft shield machine completes the excavation and support of the well, the step-by-step lifting device lifts the shaft shield machine to the wellhead. At present, the support shoe structure mainly relies on the friction force generated by the support shoe against the surface of the shaft to stabilize the shaft drilling rig vertically. The support shoe needs to provide a large radial support force, so the support requirements for the support shoe structure are high. At the same time, the support may be unstable and the shaft drilling rig may shake. Utility Model Content
