The device includes a support platform 1, with a first sliding groove 2 on the top of the support platform 1. A sliding column 3 is movably fitted inside the first sliding groove 2. A lifting frame 4 is movably fitted on the top of the sliding column 3. A lifting platform 5 is movably fitted on the top of the lifting frame 4. A first motor 6 is fixedly installed on the side of the support platform 1, with a bidirectional threaded column 7 fixedly connected to the output shaft of the first motor 6. A second motor 8 is installed on the side of the lifting platform 5, with a threaded rod 9 fixedly connected to the output shaft of the second motor 8.

A positioning post 12 is fixedly fitted to the top of the sliding block 11. A rotary table 13 is movably fitted to the top of the positioning post 12. A drive motor 14 is fixedly installed on the side of the rotary table 13. A drill bit 15 is fixedly installed on the output shaft of the drive motor 14.

A sliding ball 18 is movably fitted to the bottom of the inner cavity of the second sliding groove 10. A limit post 19 is fixedly connected to the bottom of the inner cavity of the first sliding groove 2. A moving mechanism 20 is provided at the bottom of the support table 1.

[0026] The No. 3 motor 17 is located directly above the rotary table 13, and the output shaft of the No. 3 motor 17 is fixedly sleeved on the top of the rotary table 13. By setting the No. 3 motor 17, when drilling various hole diameters, the No. 3 motor 17 is started, so that the No. 3 motor 17 drives the rotary table 13 to rotate, that is, drives the drive motor 14 to rotate, so that the drive motor 14 drives the drill bit 15 to rotate and move to the side of the rock platform. At this time, the sliding block 11 is moved, so that the sliding block 11 drives the drill bit 15 to press against the surface of the rock platform, thereby achieving the rotation adjustment effect of the drill bit 15, thus bringing convenience to drilling different hole diameters, that is, improving the practicality of the drilling device.

[0027] The threaded rod 9 is threaded inside the sliding block 11, and the threaded rod 9 is parallel to the lifting platform 5. By setting the threaded rod 9, when drilling on the rock platform, the second motor 8 is started, so that the second motor 8 can drive the sliding block 11 to move horizontally through the threaded rod 9, that is, drive the rotary table 13 to move horizontally, thereby achieving the horizontal movement effect of the drill bit 15, and thus achieving the drilling effect of rock platform drilling.

[0028] The number of sliding balls 18 is several, and the several sliding balls 18 are uniformly distributed at the bottom of the inner cavity of the second sliding groove 10. By arranging the sliding ball 18, when the threaded rod 9 drives the sliding block 11 to move horizontally, the sliding ball 18 can support and limit the horizontally moving sliding block 11, so as to avoid the problem of friction between the sliding block 11 and the bottom of the inner cavity of the second sliding groove 10 when the sliding block 11 moves horizontally, thereby improving the smoothness of the horizontal movement of the sliding block 11, that is, improving the smoothness of the horizontal movement of the drill bit 15.

[0029] The bidirectional threaded column 7 is threadedly sleeved in the inside of the sliding column 3, and the bidirectional threaded column 7 and the sliding column 3 are perpendicular to each other.

[0030] The sliding column 3 is matched with the first sliding groove 2, and the number of the sliding column 3 is two. By arranging the sliding column 3, when the bidirectional threaded column 7 drives the sliding column 3 to move horizontally, the first sliding groove 2 can limit the two horizontally moving sliding columns 3, so as to avoid the problem of inclination and deviation of the sliding column 3 when the sliding column 3 moves horizontally, thereby improving the smoothness of the horizontal movement of the sliding column 3, that is, improving the stability of the upward and downward extension of the lifting frame 4.

[0031] The material of the limiting column 19 is rubber material, and the number of the limiting column 19 is four. By arranging the limiting column 19, when the height of the lifting platform 5 is adjusted, the limiting column 19 can support and limit the descending lifting platform 5, so as to avoid the problem of impact between the top of the lifting platform 5 and the top of the supporting table 1 when the lifting platform 5 descends to the top of the supporting table 1, thereby improving the stability of the lifting platform 5.

[0032] The positioning column 12 is located directly below the rotating table 13, and the positioning column 12 and the sliding block 11 are perpendicular to each other. By arranging the positioning column 12, when the rotating table 13 is adjusted in rotation, the positioning column 12 can position the rotating table 13, so as to avoid the problem of inclination and deviation of the rotating table 13 when the rotating table 13 rotates, thereby improving the stability of the rotating table 13 when the rotating table 13 rotates.

[0033] The mobile mechanism 20 comprises a supporting column 201 fixedly connected to the bottom of the supporting table 1, and a sliding wheel 202 is installed at the bottom of the supporting column 201; when the drilling device is moved and conveyed, the supporting table 1 is pushed, so that the sliding wheel 202 drives the supporting table 1 to move horizontally, i.e. the lifting table 5 is driven to move horizontally, thereby achieving the effect of moving and conveying the drilling device, and further facilitating the adjustment of the working position of the drilling device.

[0034] The working principle of the water power station anchor beam rock table excavation drilling device is as follows:

[0035] Firstly, when drilling holes of various diameters, the third motor 17 is started, so that the third motor 17 drives the rotating table 13 to rotate, i.e. the driving motor 14 is driven to rotate, so that the driving motor 14 drives the drill bit 15 to rotate and move to the side surface of the rock table; at this time, the sliding block 11 is moved, so that the sliding block 11 drives the drill bit 15 to be pressed on the surface of the rock table, thereby achieving the effect of adjusting the rotation of the drill bit 15, thereby facilitating drilling holes of different diameters, i.e. improving the practicability of the drilling device; when drilling the rock table, the second motor 8 is started, so that the second motor 8 drives the sliding block 11 to move horizontally through the threaded rod 9, i.e. the rotating table 13 is driven to move horizontally, thereby achieving the effect of horizontal movement of the drill bit 15, and further achieving the drilling effect of the rock table; when the threaded rod 9 drives the sliding block 11 to move horizontally, the sliding ball 18 supports and limits the horizontally moving sliding block 11, so that the problem of friction between the sliding block 11 and the bottom of the inner cavity of the second sliding groove 10 is avoided, thereby improving the smoothness of the horizontal movement of the sliding block 11, i.e. improving the smoothness of the horizontal movement of the drill bit 15; when it is necessary to lift the lifting table 5, the first motor 6 is started, so that the first motor 6 drives the two sliding columns 3 to move horizontally through the bidirectional threaded column 7, so that the sliding column 3 drives the lifting frame 4 to extend, i.e. the lifting table 5 is driven to move up and down, thereby achieving the effect of adjusting the height of the rotating table 13, thereby facilitating drilling holes of different heights and diameters;

[0036] Second step: when the two-way threaded column 7 drives the sliding column 3 to move horizontally, the first sliding groove 2 can limit the two horizontally moving sliding columns 3, so that the problem of tilting deviation of the sliding column 3 when moving horizontally is avoided, thereby improving the smoothness of the sliding column 3 when moving horizontally, that is, improving the stability of the lifting frame 4 when extending up and down, when adjusting the height of the lifting platform 5, the limiting column 19 can support and limit the descending lifting platform 5, so that the problem of the lifting platform 5 colliding with the top of the support table 1 when descending to the top of the support table 1 is avoided, thereby improving the stability of the lifting platform 5, when the rotating table 13 is adjusted, the positioning column 12 can position the rotating table 13, so that the problem of tilting deviation of the rotating table 13 when rotating is avoided, thereby improving the stability of the rotating table 13 when rotating, when the drilling device is moved and conveyed, the support table 1 is pushed, so that the sliding wheel 202 can drive the support table 1 to move horizontally through the support table 1, that is, drive the lifting platform 5 to move horizontally, thereby achieving the effect of moving and conveying the drilling device, and further facilitating the work position adjustment of the drilling device.

[0037] Compared with the related art, the water power station anchor beam rock table excavation drilling device has the following beneficial effects:

[0038] By setting the third motor 17, when drilling various hole diameters, the third motor 17 is started, so that the third motor 17 drives the rotating table 13 to rotate, that is, drives the driving motor 14 to rotate, so that the driving motor 14 drives the drill bit 15 to rotate and move to the side surface of the rock table. At this time, the sliding block 11 is moved, so that the sliding block 11 drives the drill bit 15 to be pressed on the surface of the rock table, thereby achieving the effect of adjusting the type of rotation of the drill bit 15, thereby facilitating drilling of different hole diameters, that is, improving the practicality of the drilling device.
