[0014] A construction method for a water intake tunnel construction device for a water conservancy project, the construction method comprising the following steps: S1: After the water drill is rotated to drill a hole, the moving assembly is controlled to move the water drill backward, the pull rope on the winding shaft is released, and then the winding shaft pulls the slider A to slide through the pull rope, thereby moving the coring mechanism; S2: When the top end of the guide rod moves to the corner of the guide rod, the compression spring A is released, thereby inserting the clamping plate and the crowbar into the gap between the rock column and the hole wall; S3: The impact block hits the knocking rod to make the crowbar pry the rock column, and the smashing block hits the clamping plate to make the clamping plate clamp the rock column, and the whole device is moved backward to remove the rock column.

[0015] The present invention has the following advantages: 1. The present invention adopts a design of a driving mechanism. After the water drill completes drilling, the water drill moves backward and the switching frame moves leftward at the same time, thus saving a large number of steps. The design of the clamping plate and the pry bar allows the front ends of the two clamping plates and the pry bar to be inserted into the gap between the rock column and the hole wall.

As the mounting frame moves forward rapidly, the positioning plate can be freed from the restriction of the blocking plate, thereby striking the crowbar. Through the design of the smashing block, when the guide rod moves to the front corner of the triangular groove, the two smashing blocks can strike the clamping plate due to inertia, thereby clamping the rock column.

[0020] Example 1, a water conservancy project water intake tunnel construction device, such as Figure 1-Figure 3 As shown, it includes a bracket 1 and a driving motor 201 slidably installed on the lower side of the bracket 1. A water drill 202 is fixedly installed on the output shaft of the driving motor 201. A driving mechanism is provided on the bracket 1. The driving mechanism includes a switching frame 203 slidably sleeved on the bracket 1 along the left and right directions. A sliding pillar 204 is slidably installed in the switching frame 203 along the front and back directions. A compression spring A is provided between the rear side of the sliding pillar 204 and the switching frame 203. A mounting frame 205 is fixedly installed on the front side of the sliding pillar 204. A coring mechanism for removing the rock column is provided on the mounting frame 205. The coring mechanism includes a clamping plate 206 symmetrically elastically hinged to the front side of the mounting frame 205 in the upper and lower directions. A crowbar 207 elastically hinged to the mounting frame 205 is provided between the two clamping plates 206.

[0021] like Figure 3 and Figure 4As shown, the driving mechanism also includes a moving component 301 installed on the top of the bracket 1, and the moving component 301 consists of a servo motor, a screw and a connecting frame, wherein the servo motor is installed on the top of the bracket 1, one end of the screw is fixedly installed on the output shaft of the servo motor, and the other end is rotatably installed on the top of the bracket 1, and the connecting frame is rotatably sleeved on the output shaft of the drive motor 201 and is threadedly connected to the screw, and a movable frame 302 is slidably installed in the bracket 1 along the front and rear directions, and the output shaft of the drive motor 201 movably passes through the movable frame 302, and a winding shaft 303 is rotatably installed in the movable frame 302, a winding spring is provided between the top of the winding shaft 303 and the inner wall of the movable frame 302, and a pull rope is wound around the winding shaft 303, and a slider A304 is slidably installed in the bracket 1 along the front and rear directions, and the end of the pull rope is fixedly installed on the rear side of the slider A304, and the slider A304 and the top of the switching frame 203 are jointly hinged with a connecting rod 305.

[0022] like Figure 5 As shown, the driving mechanism also includes a slider B401 slidably installed on the bracket 1 along the front and rear directions, a guide column 402 is slidably installed on the slider B401, the right end of the guide column 402 is fixedly connected to the sliding pillar 204, and a compression spring B is arranged between the slider B401 and the sliding pillar 204, and the compression spring B is sleeved on the outer wall of the guide column 402.

[0023] like Figure 6 and Figure 7 As shown, a vertical slot is provided at the top of the sliding support 204 , a guide rod 501 is elastically and slidably installed in the vertical slot, and a triangular slot 502 matching the guide rod 501 is provided on the bracket 1 .

[0024] like Figure 6 and Figure 7 As shown, a switching groove 601 communicating with the triangular groove 502 is provided on the bracket 1 , and a transition surface is provided at the connection between the switching groove 601 and the triangular groove 502 .

[0025] Initially, the gap between the front ends of the two clamping plates 206 is slightly larger than the inner diameter of the water-grinding drill 202 and smaller than the outer diameter of the water-grinding drill 202. The connecting frame in the moving component 301 fits in with the front side of the movable frame 302. First, the output shaft of the servo motor in the moving component 301 is controlled to rotate. The output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the drive motor 201 to move forward through the connecting frame. The drive motor 201 drives the water-grinding drill 202 to move forward. At the same time, the output shaft of the drive motor 201 is controlled to rotate. The output shaft of the drive motor 201 drives the water-grinding drill 202 to rotate and punch. After the punching is completed, the output shaft of the servo motor is controlled to drive the lead screw to reverse, thereby making the drive motor 201 and the water-grinding drill 202 move backward. At the same time, the drive motor 201 is controlled to rotate. The output shaft of 01 no longer rotates, and the output shaft of the drive motor 201 no longer drives the water-grinding drill 202 to rotate, until the water-grinding drill 202 moves to the initial position, and the connecting frame fits the front side of the movable frame 302 again, and the output shaft of the servo motor continues to drive the lead screw to reverse, thereby causing the connecting frame, the drive motor 201 and the water-grinding drill 202 to continue to move backward. At the same time, the connecting frame squeezes the movable frame 302, and the movable frame 302 is forced to move backward. It is worth noting that the elastic force of the coil spring is less than the elastic force of the compression spring B, and the movable frame 302 cannot pull the slider A304 through the coil spring and the pull rope on the winding shaft 303. At this time, the winding shaft 303 rotates and releases the pull rope on it, the coil spring is forced to shrink, and the distance between the movable frame 302 and the slider A304 increases. Until the pull rope is completely released, the winding shaft 303 no longer rotates, the water-grinding drill 202 has moved backward a sufficient distance, and the movable frame 302 continues to move backward, so that the winding shaft 303 pulls the slider A304 through the pull rope, and the slider A304 pulls the switching frame 203 through the connecting rod 305. The switching frame 203 slides to the left under the force, and drives the mounting frame 205 and the guide column 402 to move to the left through the sliding support 204. The guide column 402 slides along the slider B401, and the compression spring B is forced to shrink. The mounting frame 205 drives the two clamping plates 206 to move to the left, and drives the crowbar 207 to move to the left, and drives the guide rod 501 to slide to the left along the switching slot 601. Then the top of the guide rod 501 is aligned with the switching slot 601 and the triangular slot 50 2, the guide rod 501 is squeezed and elastically contracts and slides until the top of the guide rod 501 passes the transition surface and contacts the inner wall of the triangular groove 502, and the guide rod 501 continues to slide to the left along the triangular groove 502. Since the water-grinding drill 202 has moved backward in advance, the sliding pillar 204 will not collide with the water-grinding drill 202 when sliding to the left, until the mounting frame 205 slides to the corner of the triangular groove 502, the compression spring A is released to drive the sliding pillar 204 to slide forward rapidly, and the sliding pillar 204 drives the mounting frame 205 and the guide pillar 402 to move forward rapidly, and the mounting frame 205 drives the two clamping plates 206 and the crowbar 207 to move forward rapidly, and the guide pillar 402 drives the slider B401 to slide forward rapidly.Until the guide rod 501 moves to the front corner of the triangular groove 502, the sliding support 204 stops moving, and the two clamping plates 206 and the crowbar 207 stop moving. At this time, the front ends of the two clamping plates 206 and the crowbar 207 are inserted into the gap between the rock column and the hole wall, so as to facilitate the subsequent knocking and removal of the rock column.

[0026] Example 2, as Figure 8 As shown, the coring mechanism also includes an impact block 701 that is slidably installed in the mounting frame 205 along the left and right directions, and a return 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 that slides through the mounting frame 205, and a positioning plate 703 is elastically hinged on the vertical plate 702. A blocking plate 704 used in conjunction with the positioning plate 703 is fixedly installed on the right side of the bracket 1. When the positioning plate 703 contacts the blocking plate 704, the impact block 701 can be limited. A knocking rod 705 used in conjunction with the crowbar 207 and the impact block 701 is elastically hinged on the right side of the mounting frame 205.

[0027] like Figure 8 As shown, a locking assembly is also included, which includes a flip rod 801 that is symmetrically and elastically hinged to the front side of the mounting frame 205. A smashing block 802 used in conjunction with the clamping plate 206 is fixedly installed on the flip rod 801. The smashing block 802 can enable the two clamping plates 206 to clamp the rock column.

[0028] like Figures 8-10 As shown, it also includes a sliding frame 901 that slides along the front and rear directions and penetrates the mounting frame 205. The front side of the sliding frame 901 is elastically hinged with a pawl 902 symmetrically in the upper and lower parts. A ratchet that engages with the pawl 902 is fixedly installed on the clamping plate 206. The pawl 902 cooperates with the ratchet to limit the clamping plate 206.

[0029] like Figures 9-11 As shown, it also includes a limit rod 903 that is slidably installed on the sliding frame 901 along the up and down directions. The top of the mounting frame 205 is provided with a through groove that matches the limit rod 903. The limit rod 903 can slide along the through groove. The limit pin 904 is symmetrically fixed on the limit rod 903, and the top of the mounting frame 205 is symmetrically provided with a limit hole that matches the limit pin 904.

[0030] After the cam 703 is in the closed position, the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate 703 is in the closed position, and the locking plate After the guide rod 501 has moved to the front corner of the triangular groove 502, the locking plate 703 passes over the blocking plate 704, and the locking plate 703 is out of the restriction. The return spring is released to drive 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 subjected to the force and rapidly elastically shrinks and rotates and knocks on the crowbar 207, causing the crowbar 207 to elastically shrink and rotate. The crowbar 207 pries the rock column to make the rock column fall off. Then the return spring shrinks and drives the impact block 701 to slide and reset relative to the mounting frame 205. The crowbar 207 and the knocking rod 705 are both elastically released and rotated to reset.

[0031] Initially, the two flip rods 801 are in a vertical state. When the mounting frame 205 drives the two clamping plates 206 and the crowbar 207 to move forward rapidly, the two flip rods 801 are driven 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 smashing block 802 is affected by inertia and drives the flip rod 801 to elastically contract and rotate rapidly forward, and knock on the corresponding clamping plate 206. The two clamping plates 206 are subjected to the same force. The two levers 801 are rotated and brought into rotation, and the ratchet wheels 802 are pressed against the pawls 902, which are elastically contracted and released to rotate until the two clamping plates 206 clamp the rock column. The pawls 902 limit the clamping plates 206 through the ratchet wheels, so that the two clamping plates 206 keep clamping the rock column. Then the two flip rods 801 are elastically released and rotated to reset, and drive the smashing block 802 to reset, thereby completing the shedding and clamping of the rock column, and then the whole device is moved backward to take out the rock column.

[0032] After the rock column is taken out, the staff will lift the limit rod 903, which drives the two limit pins 904 to lift upward, so that the two limit pins 904 are separated from the limit holes of the mounting frame 205. The limit rod 903 is then pushed backward, and the limit rod 903 drives the sliding frame 901 and the two limit pins 904 to move backward. The sliding frame 901 drives the two pawls 902 to move backward. After the pawls 902 move, they no longer contact the ratchet. The ratchet is separated from the restriction, allowing the clamping plate 206 to move, and the clamping plate 206 no longer contacts the ratchet. The rock column is clamped. After the rock column is removed, the clamping plate 206 is elastically released and rotated to reset. Then the limit rod 903 is pushed forward to make the sliding frame 901 and the two limit pins 904 move forward. The sliding frame 901 drives the two pawls 902 to move forward. After the pawls 902 move, they contact the ratchet again. Then the limit rod 903 is pressed down to make the two limit pins 904 insert into the limit holes of the mounting frame 205. Then the servo motor output shaft in the moving assembly 301 is controlled to rotate, thereby making the connecting frame and the drive motor 201 move forward. As the water drill 202 moves forward, the compression spring B is released to push the sliding pillar 204 to move to the right. The sliding pillar 204 drives the guide rod 501 to move. The guide rod 501 is squeezed by the inner wall of the triangular groove 502, causing the sliding pillar 204 to move to the right rear. The compression spring A is forced to shrink, and then the locking plate 703 contacts the left side of the blocking plate 704. The locking plate 703 is squeezed by the blocking plate 704 and elastically shrinks and rotates to the left. The sliding pillar 204 continues to move to the right rear until the locking plate 703 passes over the blocking plate. 704, the locking plate 703 is elastically released and rotated to reset, and then the guide rod 501 moves to the initial position, and the guide rod 501 is elastically released and slides into the switching slot 601. At this time, the switching frame 203 drives the slider A304 to reset through the connecting rod 305, and the movable frame 302 continues to move forward. The coil spring is released to drive the winding shaft 303 to rotate, and the winding shaft 303 rewinds the pull rope until the movable frame 302 is reset, the coil spring is completely released, and the servo motor in the moving component 301 is turned off, thereby completing the reset of the entire device.

[0033] A construction method for a water intake tunnel construction device for a water conservancy project comprises the following steps: S1: After the water drill 202 is rotated and drilled, the moving assembly 301 is controlled to move the water drill 202 backward, and the pull rope on the winding shaft 303 is released. Then, the winding shaft 303 pulls the slider A304 to slide through the pull rope, thereby moving the coring mechanism; 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, thereby allowing the clamping plate 206 and the crowbar 207 to be inserted into the gap between the rock column and the hole wall; S3: The impact block 701 strikes the striking rod 705 to make the crowbar 207 pry the rock column, and the smashing block 802 strikes the clamping plate 206 to make the clamping plate 206 clamp the rock column, and the entire device is moved backward to remove the rock column.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
