Abstract
The invention provides an impact mole steering mechanism, comprising a mechanism outer shell body25. An end cover is arranged on the front end of the mechanism outer shell body25 and a mechanism tailstock28 is arranged on the tail end of the mechanism outer shell body25. A transfer core2 is installed in the head cover and a hollow wimble 1is installed on the transfer core2. A swing cylidner12 and a rotary push cylinder25 are arranged in the mechanism outer shell body25. The front end of the swing cylidner12 is hinged with a pull rod through a cylinder connecting pin9 and the pull rod; and the tail end is hinged with a rotary sleeve16. The other end of the pull rod is hinged with the transfer core2; the other end of the rotary sleeve16 is connected with the rotary push cylinder25, the other end of which is connected with the mechanism tailstock28. Installed at the head of the impact mole, the steering mechanism is improved in motion flexibility. Meanwhile, the turning of the steering mechanism is realized through a revolving gear, thus dispensing with a drill pipe, a gas tube or a flexible bar commonly used both home and abroad to transfer torque from the ground to an aiguille. Therefore, the impact mole steering mechanism is simple in structure and convenient to operate.

Steering mechanism of the present invention is mounted in the impact pike head, by the steering angle of control head, controls the direction that impact pike advances, and the motive force of its entire equipment and rotatory force all result from the body of impact pike, has improved the flexibility of motion.Simultaneously it rotates by rotating mechanism and realizes, saved the existing need that generally adopt both at home and abroad with moment of torsion by the drilling rod, wireway or the flexibility bar that are passed to drill bit on the ground, thereby, simple in structure, easy to operate.
During straight line boring, keep initial position motionless by the cylinder (or oil cylinder) in the control system control steering mechanism, start simultaneously to beater mechanism air feed (or fuel feeding), produce ballistic motion, the hole track of formation is a straight line;
During curve boring, when track is advanced in the needs adjustment, by cylinder (or oil cylinder) action in the control system control steering mechanism, make tapered head produce different azimuths, like this, robot will advance along the direction of taper bit deflection, also just realize curvilinear motion.
The present invention is that the 200510010118.3 pluses and minuses contrasts of comparing are as follows with application number:
| Steering mechanism originally | Steering mechanism of the present invention | |
| 1, degree of freedom, flexibility | 1, flexibility is relatively poor | 2, flexibility is good |
| 2, straight ahead | Near linear is because of its head cusp is a helix | |
| 3, curve | Be fixedly corner, constant bearing angle | Be angle adjustable, direction-adjustable angle |
