Abstract
The utility model discloses a two enlargers that drive, including the enlarger body, the mud of enlarger body pierces the end and is equipped with the connecting rod of being connected with the drilling rod, hydraulic pressure mud motor of play thick liquid end installation of enlarger body, hydraulic pressure mud motor is equipped with the pressure source entry towards the one end of enlarger body, and the pressure source entry accesss to the blade of hydraulic pressure mud motor, and the output shaft and the pivot of enlarger body of hydraulic pressure mud motor are connected, enlarger body, connecting rod, hydraulic pressure mud motor coaxial arrangement, at hydraulic pressure mud motor of play thick liquid end installation of enlarger, messenger's enlarger power is sufficient, when the reaming, the success of reaming once only, the reduction of erection time, saved the energy, reduced engineering cost.
Description
Technical field
This utility model relates to rig, drives reamer particularly to a kind of pair.
Background technology
When general Underground Crossing directional hole construction, after drill bit punches ground, need to change drill bit, connect reamer and carry out reverse drawing reaming, but due to reamer jointed rod after, drilling rod drive reamer to rotate, power is limited, reaming cannot directly diffuse into target aperture, it is necessary to reaming step by step, the most not only wastes resource but also delay the duration.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pair and drives reamer, this reamer is using hydraulic cement slurry motor and drilling rod as driving power, increase the dynamical system of reamer, enable reamer across level reaming, disposably boring is diffused into target aperture.
For achieving the above object, this utility model provides following technical scheme: a kind of pair is driven reamer, including reamer body, the mud of described reamer body pierces end and is provided with the connecting rod being connected with drilling rod, the slurry output end of described reamer body installs a hydraulic cement slurry motor, hydraulic cement slurry motor is provided with pressure source inlet towards one end of reamer body, pressure source inlet leads to the blade of hydraulic cement slurry motor, the output shaft of hydraulic cement slurry motor is connected with the rotating shaft of reamer body, and described reamer body, connecting rod, hydraulic cement slurry motors are installed.
Preferably, the pressure source inlet of hydraulic cement slurry motor installs bypass valve.
Using technique scheme, the slurry output end at reamer installs a hydraulic cement slurry motor, makes reamer power sufficient, when reaming, it is possible to disposable reaming success, reduction of erection time, and reamer is operationally, the mud that slush pump pumps into, under the pressure effect of slush pump, enters in hydraulic cement slurry motor from the slurry output end of reamer, drives rotor to rotate around axis stator, hydraulic cement slurry motor produces moment of torsion and rotating speed, pass to reamer, thus save the energy, decrease engineering cost.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is utility model works environment schematic；
Detailed description of the invention
Below in conjunction with the accompanying drawings, by the description to embodiment, this utility model is described further:
As shown in Figure 1, a kind of pair of this utility model drives reamer, including reamer body 1, the mud of reamer body 1 pierces end and is provided with the connecting rod 2 being connected with drilling rod, the slurry output end of reamer body 1 installs a hydraulic cement slurry motor 3, hydraulic cement slurry motor 3 is provided with pressure source inlet towards one end of reamer body 1, the pressure source inlet of hydraulic cement slurry motor 3 installs bypass valve, bypass valve leads to the blade of hydraulic cement slurry motor 3, the output shaft of hydraulic cement slurry motor 3 is connected with the rotating shaft of reamer body 1, reamer body 1, connecting rod 2, hydraulic cement slurry motor 3 is co-axially mounted.
This utility model installs a hydraulic cement slurry motor at the slurry output end of reamer, makes reamer power sufficient, when reaming, it is possible to disposable reaming success, reduction of erection time.
As shown in Figure 2, as a example by Chuan He hole, when drilling through river course 4 and get through boring, drill bit 5 is changed, install this utility model to be pulled back to carry out reaming, the mud that slush pump 6 pumps into from mud pit 7, under the pressure effect of slush pump 6, enters in hydraulic cement slurry motor 3 from the slurry output end of reamer, drives rotor to rotate around axis stator, hydraulic cement slurry motor 3 produces moment of torsion and rotating speed, pass to reamer, thus save the energy, decrease engineering cost.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
