[0031] The utility model principle:

[0032] In the construction process, first, the top pull drill machine 1 is installed and debugged, and it is ensured that the laser emitter 7, the electromagnetic guide instrument 13, the synchronous display 8 and the synchronous display two 14 are in the normal working state.

[0033] The top pull drill machine 1 is started, the power box main shaft drives the rotary joint assembly 2 to rotate, power is transmitted to the double-wall drill pipe 4 through the transition joint 3, and then the guide drill bit 5 is driven to rotate and drill.

[0034] When drilling at close range, mainly rely on laser guide to control trajectory. The laser beam emitted by the laser emitter 7 passes through the through hole of the top pull drill machine 1 main shaft and the rotary joint assembly 2, focuses on the center of the laser target 6 in the target seat 51 of the guide drill bit 5, and the focused image is transmitted to the synchronous display 8. The operator observes the synchronous display 8 in real time, and when the focused light spot on the laser target 6 is found to deviate, the guide drill bit 5 is rotated by controlling the power head, and the direction of the reversing slope 53 of the drill bit 52 is adjusted.

The operator holding the guide instrument feeds back the relevant information to the construction personnel through the communication equipment, and the construction personnel adjusts the drilling trajectory in time according to the display data, so as to ensure that the drilling is along the predetermined path.

[0036] During the drilling process, the cooling water enters through the water injection hole 21 of the rotary joint assembly 2, passes through the water passing hole 22, the water passing hole of the transition joint 3, the water passing channel 45 of the double-wall drill pipe 4, the water passing hole 511 of the target seat 51, the water passing hole two 111 of the electromagnetic guide shaft 11, and finally sprays out from the water injection hole 521 of the drill bit 52, the sprayed water cools the drill bit 52 and scatters the slag produced by the drilling at the same time. Through the above operation, the utility model can effectively improve the guiding accuracy and working efficiency of the top pull drill 1; through the combination of the laser guiding and the electromagnetic guiding, the utility model makes up for the deficiency of the single guiding technology, realizes the high-precision control of the drilling track, improves the construction efficiency and engineering quality, and can realize the water injection cooling at the same time.
