Description
Technical field
The invention belongs to hard rock driving technology field, particularly relate to a kind of drilling equipment and the hard rock driving method that are installed in hard rock mole.
Background technology
Hard rock tunnels, and popular saying is exactly the excavation to hard-rock tunnel, and in order to better realize this object, person skilled just have devised special equipment, hard rock mole.Hard rock mole is a kind of large-scale heading equipment having gathered the technology such as hydraulic pressure, control, electromechanics, is widely used in roadway construction and the construction of various hard rock geology.And existing hard rock mole cannot, in the face of whole hard rock geology, once run into rock mass really up to the mark, will cause cutting efficiency low, the pick serious wear in cutterhead causes shorten its application life.
Summary of the invention
For prior art Problems existing, the invention provides a kind of drilling equipment and the hard rock driving method that are installed in hard rock mole, the present invention not only increases the cutting efficiency of hard rock mole, and extends the application life of pick in cutterhead.
To achieve these goals, the present invention adopts following technical scheme: a kind of drilling equipment being installed in hard rock mole, comprise backplate, Connection Block, telescoping cylinder, drive motors and drill bit, described drill bit is connected with the output of drive motors, described drive motors is connected with one end of telescoping cylinder, the other end of described telescoping cylinder is fixed in Connection Block, and described drive motors is matched by track with Connection Block; Described backplate is arranged on the top of telescoping cylinder, drive motors and drill bit.
A kind of hard rock driving method being installed in the drilling equipment of hard rock mole described in employing, the cutterhead of described drilling equipment and hard rock mole with the use of, comprise the following steps:
Step one: effectively cannot tunnel if cutterhead runs into solid rock, then make cutterhead quit work;
Step 2: start drilling equipment, under the driving of telescoping cylinder, drive motors and drill bit start to protract, until touching rock mass, now telescoping cylinder stops driving;
Step 3: drive motors starts, and drives drill bit rotational, and when the stabilization of speed of drill bit, telescoping cylinder drives again, impels drive motors and drill bit to continue to protract, and now drill bit starts to carry out bore operation to rock mass;
Step 4: after drilling depth reaches desired depth, telescoping cylinder carries out reverse drive, and drive motors and drill bit are return simultaneously, until initial position, simultaneous retractable cylinder stops driving;
Step 5: adjustment hard rock mole cutting arm, makes drilling equipment carry out bore operation at the diverse location of rock mass, until complete scheduled plan, and get back to initial position, now drilling equipment completes drill tasks and quits work simultaneously;
Step 6: cutterhead recovers to start, and carries out reaming cut one by one to the hole of having bored.
Beneficial effect of the present invention:
Hard rock mole and the hard rock driving method thereof of drilling equipment of the present invention are installed, overcome existing hard rock mole weak point technically, for hard rock mole provides a kind of novel tunneling method integrating boring, tunnel, high efficiency, high-quality excavation operation can be realized to high rigidity rock mass, extend the application life of pick in cutterhead simultaneously, greatly reduce tunneling construction cost.

In figure, 1-backplate, 2-Connection Block, 3-telescoping cylinder, 4-drive motors, 5-drill bit, 6-taper cutterhead.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of drilling equipment being installed in hard rock mole, comprise backplate 1, Connection Block 2, telescoping cylinder 3, drive motors 4 and drill bit 5, described drill bit 5 is connected with the output of drive motors 4, described drive motors 4 is connected with one end of telescoping cylinder 3, the other end of described telescoping cylinder 3 is fixed in Connection Block 2, and drive motors 4 is matched by track with Connection Block 2; Described backplate 1 is arranged on the top of telescoping cylinder 3, drive motors 4 and drill bit 5, and with Connection Block 2 Joint.
As shown in Figure 2, before using, first drilling equipment of the present invention is fixed on the top of hard rock mole cutting units by Connection Block 2, the cutting units of hard rock mole adopts taper cutterhead 6.The control end of described drive motors 4 and telescoping cylinder 3 is arranged in the control room of hard rock mole.When running into hard rock mass in hard rock mole tunneling process, if now still utilize taper cutterhead 6 to carry out headwork by force, not only drivage efficiency can reduce greatly, also can badly damaged taper cutterhead 6 and interior pick thereof, so now just need drilling equipment and taper cutterhead 6 with the use of, to have continued headwork below.
A kind of hard rock driving method being installed in the drilling equipment of hard rock mole described in employing, the taper cutterhead 6 of described drilling equipment and hard rock mole with the use of, comprise the following steps:
Step one: cannot effectively tunnel if taper cutterhead 6 runs into solid rock, then make taper cutterhead 6 quit work;
Step 2: start drilling equipment, under the driving of telescoping cylinder 3, drive motors 4 and drill bit 5 start to protract, until touching rock mass, now telescoping cylinder 3 stops driving;
Step 3: drive motors 4 starts, and drive drill bit 5 to rotate, when the stabilization of speed of drill bit 5, telescoping cylinder 3 drives again, impels drive motors 4 and drill bit 5 to continue to protract, and now drill bit 5 starts to carry out bore operation to rock mass;
Step 4: after drilling depth reaches desired depth, telescoping cylinder 3 carries out reverse drive, and drive motors 4 and drill bit 5 are return simultaneously, until initial position, simultaneous retractable cylinder 3 stops driving;
Step 5: adjustment hard rock mole cutting arm, makes drilling equipment carry out bore operation at the diverse location of rock mass, until complete scheduled plan, and get back to initial position, now drilling equipment completes drill tasks and quits work simultaneously;
Step 6: taper cutterhead 6 is resumed work, and one by one reaming cut is carried out to the hole of having bored.
