[0049] As shown in Figure 8 The core taking mechanism further comprises an impact block 701 slidingly installed in the mounting frame 205 in the left-right direction, a reset spring is arranged between the right side of the impact block 701 and the inner wall of the mounting frame 205, a vertical plate 702 is fixedly installed on the impact block 701 through a support rod slidingly penetrating the mounting frame 205, the vertical plate 702 is elastically hinged with a clamping plate 703, the right side of the bracket 1 is fixedly installed with a blocking plate 704 used in cooperation with the clamping plate 703, the clamping plate 703 can limit the impact block 701 when in contact with the blocking plate 704, and the right side of the mounting frame 205 is elastically hinged with a knocking rod 705 used in cooperation with the crowbar 207 and the impact block 701.

[0050] As shown in Figure 8 Further comprising a locking assembly, the locking assembly comprises a turnover rod 801 symmetrically and elastically hinged on the front side of the mounting frame 205, the turnover rod 801 is fixedly installed with a hammer block 802 used in cooperation with the clamping plate 206, and the two clamping plates 206 can clamp the rock column through the hammer block 802.

[0051] As shown in Figures 8-10 Further comprising a sliding frame 901 slidingly penetrating the mounting frame 205 in the front-rear direction, the front side of the sliding frame 901 is symmetrically and elastically hinged with a pawl 902, the clamping plate 206 is fixedly installed with a ratchet wheel engaged with the pawl 902, and the clamping plate 206 can be limited through cooperation of the pawl 902 and the ratchet wheel.

[0052] As shown in Figures 9-11 Further comprising a limiting rod 903 slidingly installed on the sliding frame 901 in the up-down direction, the top of the mounting frame 205 is provided with a penetrating slot matched with the limiting rod 903, the limiting rod 903 can slide along the penetrating slot, the limiting rod 903 is symmetrically fixedly installed with a limiting pin 904, and the top of the mounting frame 205 is symmetrically provided with a limiting hole matched with the limiting pin 904.

[0053] At the beginning, the reset spring is in the released state, and there is a gap between the clamping plate 703 and the blocking plate 704. When the mounting frame 205 moves to the left, the impact block 701 and the knocking rod 705 are driven to move to the left. The impact block 701 drives the clamping plate 703 to move to the left through the vertical plate 702 and the support rod. Then the clamping plate 703 contacts the right side of the blocking plate 704. The mounting frame 205 continues to move to the left, and the clamping plate 703 is limited by the blocking plate 704 to stop moving through the vertical plate 702 and the support rod. The reset spring is forced to contract until the mounting frame 205 slides forward rapidly. The mounting frame 205 drives the impact block 701 and the knocking rod 705 to move forward rapidly, and drives the clamping plate 703 to move forward rapidly through the vertical plate 702 and the support rod. The clamping plate 703 moves forward rapidly along the blocking plate 704 until the guide rod 501 moves to the front corner of the triangular groove 502. The clamping plate 703 passes over the blocking plate 704, and the clamping plate 703 is released from the limit. The reset spring drives the impact block 701 to slide to the left. When the impact block 701 slides to the initial position, the impact block 701 continues to slide to the left under the influence of inertia and hits the knocking rod 705. The knocking rod 705 is rapidly and elastically contracted under the force and rotates and hits the lever 207, causing the lever 207 to elastically contract and rotate. The lever 207 pries the rock column to make it fall off. Then the reset spring drives the impact block 701 to slide relative to the mounting frame 205 to reset. The lever 207 and the knocking rod 705 are elastically released and rotated to reset.

[0054] At the beginning, the two flip rods 801 are in a vertical state. When the mounting frame 205 drives the two clamping plates 206 and the lever 207 to move forward rapidly, it also drives the two flip rods 801 to move forward rapidly until the guide rod 501 moves to the front corner of the triangular groove 502. The mounting frame 205 stops moving, and the impact block 802 drives the flip rod 801 to elastically contract and rotate forward under the influence of inertia and hits the corresponding clamping plate 206. The two clamping plates 206 rotate and drive the ratchet to rotate under the force. The ratchet presses the pawl 902, and the pawl 902 is continuously elastically contracted and released under the force. The two clamping plates 206 hold the rock column until the pawl 902 limits the clamping plate 206 through the ratchet to keep the two clamping plates 206 holding the rock column. Then the two flip rods 801 are elastically released and rotated to reset, and the impact block 802 is reset. Thus, the rock column is removed and clamped, and then the whole device is moved backward to take out the rock column.

[0055] After the rock column is taken out, the staff member lifts the limiting rod 903, the limiting rod 903 drives the two limiting pins 904 to lift upward, the two limiting pins 904 are separated from the limiting holes of the mounting frame 205, the limiting rod 903 is pushed backward, the limiting rod 903 drives the sliding frame 901 and the two limiting pins 904 to move backward, the sliding frame 901 drives the two pawls 902 to move backward, the pawls 902 no longer contact the ratchet wheel after moving, the ratchet wheel is separated from the limitation, the clamping plate 206 can move, the clamping plate 206 no longer clamps the rock column, after the rock column is taken out, the clamping plate 206 is elastically released to rotate and reset, then the limiting rod 903 is pushed forward, the sliding frame 901 and the two limiting pins 904 move forward, the sliding frame 901 drives the two pawls 902 to move forward, the pawls 902 contact the ratchet wheel again after moving, then the limiting rod 903 is pressed downward, the two limiting pins 904 are inserted into the limiting holes of the mounting frame 205, the output shaft of the servo motor in the moving assembly 301 is controlled to rotate, and then the connecting frame, the driving motor 201 and the water mill drill 202 move forward, the compression spring B is released to drive the sliding support 204 to move rightward, the sliding support 204 drives the guide rod 501 to move, the guide rod 501 is extruded by the inner wall of the triangular groove 502, the sliding support 204 moves rightward and rearward, the compression spring A is contracted under the force, then the clamping plate 703 contacts the left side of the blocking plate 704, the clamping plate 703 is extruded by the blocking plate 704 to elastically contract and rotate leftward, the sliding support 204 continues to move rightward and rearward, until the clamping plate 703 passes the blocking plate 704, the clamping plate 703 is elastically released to rotate and reset, then the guide rod 501 moves to the initial position, the guide rod 501 is elastically released to slide and clamped into the switching groove 601, at this time the switching frame 203 drives the sliding block A 304 to reset through the connecting rod 305, the movable frame 302 continues to move forward, the coil spring is released to drive the winding shaft 303 to rotate, the winding shaft 303 winds the pull rope, until the movable frame 302 resets, the coil spring is completely released, the servo motor in the moving assembly 301 is turned off, and thus the reset of the overall device is completed.

[0056] A construction method of a water conservancy project water intake tunnel construction device, comprising the following steps:

[0057] S1: after the water mill drill 202 is rotated to punch a hole, the moving assembly 301 is controlled to move the water mill drill 202 rearward, the pull rope on the winding shaft 303 is released, then the winding shaft 303 pulls the sliding block A 304 to slide through the pull rope, and then the coring mechanism moves;

[0058] S2: when the top end of the guide rod 501 moves to the corner of the guide rod 501, the compression spring A is released, and then the clamping plate 206 and the crowbar 207 are inserted into the gap between the rock column and the hole wall;

[0059] S3: knock the lever 705 by the impact block 701, make the lever 207 pry the rock column, knock the clamping plate 206 by the hammer block 802, make the clamping plate 206 clamp the rock column, move the whole device backward to take out the rock column.
