6. The automatic entry and exit well device of claim 1,
the walking driving structure is connected with the host through a walking box, the driving walking gear is installed in the walking box, and partial gear teeth of the driving walking gear extend out of the walking box and are meshed with the guide rail.
7. The automatic entry and exit well device of claim 6,
the automatic well device of cominging in and going out still includes an at least driven running gear, at least one initiative running gear and at least one driven running gear follows the circumference interval of shaft is arranged, follow on the internal face of shaft the circumference interval of shaft is arranged two at least the guide rail, driven running gear includes driven running gear, install two at least on the host computer the walking case, driven running gear installs in another in the walking case, just the part teeth of a cogwheel of driven running gear stretch out from this walking case, and with another the guide rail meshing is connected, driven running gear can with initiative running gear synchronous rotation and roll along this guide rail.
8. The automatic entry and exit well device of claim 1,
the shaft is formed by assembling a plurality of sections of steel pipe sheets along the axial direction of the shaft, at least one guide rail section is arranged on the inner wall surface of each section of steel pipe sheet along the axial direction of the shaft, and at least one guide rail section on each section of steel pipe sheet is assembled along the axial direction of the shaft to form at least one guide rail.
9. A shaft boring machine comprising the main machine and an automatic shaft entry and exit apparatus as claimed in any one of claims 1 to 8.
10. A shaft construction method characterized by using the shaft heading machine of claim 9, comprising the steps of:
entering the equipment into a well: the walking driving structure drives the driving walking gear to roll downwards along the guide rail until the excavation end of the main machine is contacted with the soil body below the main machine;
and (3) shaft tunneling: the host machine tunnels downwards, and the shaft and the host machine sink synchronously until the excavation end of the host machine reaches a set depth;
and (3) equipment goes out of the well: when the host machine fails in the tunneling process or the construction of the vertical shaft is completed, the traveling driving structure drives the driving traveling gear to roll upwards along the guide rail until the host machine extends out of the vertical shaft.
11. A shaft construction method as claimed in claim 10, wherein the excavated end is formed to a predetermined depth to form a concave structure in a bottom of the shaft, and the shaft driving step further comprises the steps of:
the walking driving structure drives the driving walking gear to roll upwards along the guide rail until a space for swinging the excavation end is formed above the concave surface structure;
swinging the excavation end to a position on the concave structure higher than the set depth;
the main machine tunnels downwards, and the walking driving structure drives the driving walking gear to synchronously roll downwards along the guide rail along with the main machine;
and repeating the steps until the concave structure forms a well bottom plane of the vertical well, and the well bottom plane is flush with the set depth.
