11st, since situ of drilling well is there are flammable explosive gas, make situ of drilling well safer using hydraulic motor.With fluid cylinder
Using identical power, without increasing other power sources newly, equipment is easy for installation.Torque Performance of Hydraulic Motor is big, is without increase retarder
It can obtain high torque so that equipment is simple.Meanwhile hydraulic motor is also cooled down constantly by hydraulic oil in the running, does not deposit
In overheat risk.
12nd, while hydraulic motor drives drive shaft turns, driving key is with drive shaft turns, while driving key drives spiral shell
Column rotates, and stud can advance or retreat in screw hole during rotation, and stud is during advance or retrogressing, transmission
Key slides in the groove I in stud axis hole, is keeping the position of drive shaft and driving key relative to the static feelings of locking system
Under condition, stud is set to advance or retreat.The driving force of drive shaft is passed to by stud by driving key, can allow the position of hydraulic motor
Put and remain unchanged, at the same do not allow yet hydraulic motor drive shaft directly and Stud connection, prevent that the drive shaft of hydraulic motor is direct
The axial force of stud is born, while locking system locking effect is ensured, avoids stud from being damaged to hydraulic motor.
13rd, when the utility model is used, first pulling out sliding part along sliding slot, dead card component II is opened along hinge joint,
Dead card component I and dead card component II are sleeved on drilling rod, close dead card component I and dead card component II, sliding part is pushed away along sliding slot
Enter.Hydraulic oil is passed through into fluid cylinder, the piston allowed in fluid cylinder compresses dead card component II, is then existed again by fluid motor-driven stud
Rotation, the dead card component I of locking and dead card component II in screw hole, after stud completes locking, the hydraulic pressure in fluid cylinder is released.Work as needs
When removing dead card, hydraulic oil is first passed through into fluid cylinder, the piston allowed in fluid cylinder compresses dead card component II, then passes through hydraulic pressure horse again
Reversely rotated up to driving stud in screw hole, cancel the locking to dead card component I and dead card component II, treat that stud has reversely rotated
Cheng Hou, the hydraulic pressure in fluid cylinder is released.By being passed through hydraulic oil, hydraulic motor is reduced in driving stud in locking and the mistake opened
The power provided is provided in journey, reduces the power of hydraulic motor, saves the energy.Also make the locking of stud at the same time and open more square
Just.
