Embodiment
As shown in figure 1, drilling rod drive device is mainly made up of tap 1, hydraulic motor 4, connecting rod 2 and gearbox 5.Two
The two ends of connecting rod 2 are provided with left-right rotary screw thread, and its one end is threadedly coupled with tap 1, and the other end is carried out with gearbox 5
Threaded connection, is mainly used in the position relationship between adjustable tap central tube 3 and output shaft of gear-box 502, to ensure the fire hose
The axiality of head central tube 3 and output shaft of gear-box 502.Hydraulic motor 4 is fixedly connected on transmission input shaft 501, speed change
Case output shaft 502 is slender rectangular tube, and it is provided at both ends with tubing round thread, and one end carries out tubing round thread company with swivel stem 3
Connect, the other end carries out tubing round thread with drilling rod 6 and is connected.
As shown in Fig. 2 transmission input shaft 501, output shaft of gear-box 502, jackshaft I 514, jackshaft II 524 are solid
Surely it is connected on casing 503.Driving gear I 511 is fixedly connected on transmission input shaft 501, is provided with jackshaft I 514
Hydraulic clutch I 513, driven gear I 512 is fixedly connected on hydraulic clutch I 513, and low-grade input gear 515 is fixedly connected
On jackshaft I 514, low-grade output gear 516 is fixedly connected on output shaft of gear-box 502；Driving gear II 521, which is fixed, to be connected
