Description
Technical Field
[0001] The invention relates to the technical field of anchor cable drilling positioning, and in particular to an NPR anchor cable construction drilling directional controller. Background Art
[0002] Anchor cable refers to the process of anchoring the main cable in the side hole of a suspension bridge. The main cable is divided into many steel bundles and anchored in anchor ingots respectively. These steel bundles are called anchor cables. The anchor cable is fixed to the slope surface with the outer end and anchored in the stable rock mass within the sliding surface at the other end. The prestressed steel strand that passes through the sliding surface of the slope directly produces anti-slip resistance on the sliding surface, increases anti-slip friction resistance, and puts the structural surface in a compressed state to improve the integrity of the slope rock mass, thereby fundamentally improving the mechanical properties of the rock mass, effectively controlling the displacement of the rock mass, and promoting its stability, so as to achieve the purpose of regulating the bedding, landslides, dangerous rocks and stones. Drilling is a key process for controlling the construction period in anchor cable construction.

A through opening 30 located above the slide opening 15 is provided on one side of the mounting seat 4. A sliding rod 22 is symmetrically provided on the top of the accommodating chamber 5. A slide plate 20 sliding on the inner wall of the accommodating chamber 5 is provided above the spherical seat 6. One end of the slide plate 20 passes through the through opening 30 and extends to the outside of the accommodating chamber 5. A bevel 25 is provided at one end of the slide plate 20 close to the accommodating chamber 5. A pushing unit connected to the bevel 25 is fixedly provided on the inner wall of the through opening 30. A through hole 24 is provided which is slidably sleeved on the outside of the slide rod 22, a spring 23 connected to the top of the slide plate 20 is sleeved on the outside of the slide rod 22, a clamping rod 21 extending to the inside of the clamping groove 19 is fixedly connected to the middle position of the bottom end of the slide plate 20, the pushing unit includes a slide seat 26 fixedly connected to the bottom end of the through hole 30, a screw rod 27 is rotatably installed on the inner wall of the slide seat 26, a threaded seat 29 is sleeved on the screw rod 27, the screw rod 27 is threadedly connected to the threaded seat 29, the threaded seat 29 is in sliding contact with the bottom end of the slide seat 26, a slider 28 is fixedly connected to the top of the threaded seat 29, the slider 28 is a trapezoidal structure, and the side wall of the slider 28 is in sliding contact with the hypotenuse 25, the angle detection part includes a dial 12 installed on one side of the mounting seat 4, one end of the mounting shaft 11 passes through the middle position of the dial 12, one end of the mounting shaft 11 is fixedly connected to a ferrule 13, and the outer wall of the ferrule 13 is fixedly connected to a pointer 14 located on one side of the dial 12;
[0038] When the angle of the limit cylinder 8 needs to be adjusted, the screw rod 27 is first rotated. Through the threaded connection relationship between the screw rod 27 and the threaded seat 29 and the sliding connection relationship between the threaded seat 29 and the sliding seat 26, the slider 28 is moved laterally. Through the sliding of the slider 28 and the bevel 25 and the squeezing of one end of the slide plate 20, the through hole 24 on the slide plate 20 is moved upward on the outside of the slide rod 22 to achieve the squeezing of the spring 23.

The worm wheel 18 will drive the installation shaft 11 to rotate, and the installation shaft 11 will drive the spherical seat 6, the connecting rod 7, the limit cylinder 8, the rotating plate 9 and the laser light 10 to swing synchronously, so as to achieve the angle adjustment of the limit cylinder 8, and the installation shaft 11 The rotation will drive the ring 13 to rotate, and the ring 13 will drive the pointer 14 to swing synchronously on one side of the dial 12, so that the inclination angle of the limit cylinder 8 can be intuitively known according to the position of the pointer 14 on the dial 12, so as to effectively and accurately adjust the inclination angle of the limit cylinder 8 and realize precise directional control of the drilling of the NPR anchor cable construction. When the inclination angle of the limit cylinder 8 is consistent with the required drilling angle of the NPR anchor cable construction, the motor 16 is stopped, and then the screw rod 27 is rotated in the reverse direction to make the slider 28 move in the reverse direction. Through the sliding contact relationship between the slider 28 and the hypotenuse 25 and the reverse force of the spring 23, the slide plate 20 drives the clamping rod 21 to move downward, so that the clamping rod 21 is inserted into the clamping groove 19, and the spherical seat 6 is locked again, and the inclination direction of the limit cylinder 8 is effectively fixed, thereby effectively performing directional operation for the drill rod drilling, thereby ensuring the directional drilling quality of the drill rod.

[0040] When the inclination angle of the limit cylinder 8 is adjusted to be in the same direction as the NPR anchor cable construction angle, the position of the laser lamp 10 is adjusted so that the laser emitted by the laser lamp 10 coincides with the marked NPR anchor cable construction position. The staff puts the drill rod in the limit cylinder 8 and starts the motor 2 41. The motor 2 41 drives the gear 2 42 to rotate. Through the meshing connection between the gear 2 42 and the gear ring 40, the gear ring 40 drives the socket 39 to rotate. The socket 39 drives the arc groove 44 to rotate. Through the movement of the moving rod 45 and the arc groove 44 and the strip groove 43, the drill rod 41 is rotated. The sliding connection relationship will cause the moving rod 45 to slide in the arc groove 44 and the strip groove 43, and the moving rod 45 will drive the clamping plates 46 to approach each other through the mounting rod, so that the four clamping plates 46 are close to the outer wall of the drill pipe, which is convenient for the four clamping plates 46 to clamp the outer wall of the drill pipe.

[0041] The implementation principle of an NPR anchor cable construction drilling directional controller in the embodiment of the present application is as follows: when it is necessary to adjust the angle of the limit cylinder 8, the screw rod 27 is first rotated, and the slider 28 is moved laterally through the threaded connection relationship between the screw rod 27 and the threaded seat 29 and the sliding connection relationship between the threaded seat 29 and the sliding seat 26. The sliding of the slider 28 and the bevel 25 and the squeezing of one end of the slide plate 20 facilitate the upward movement of the through hole 24 on the slide plate 20 on the outside of the slide rod 22 to achieve the squeezing of the spring 23. At the same time, the slide plate 20 drives the clamping rod 21 to disengage from the clamping groove 19 and disconnect the lock on the spherical seat 6. Then, the motor 16 is started, and the motor 16 realizes the rotation of the worm 17. The meshing connection relationship between the worm 17 and the worm wheel 18 makes the worm wheel 18 rotate, and the worm wheel 18 drives the installation shaft 11 to rotate. The installation shaft 11 drives the spherical seat 6, the connecting rod 7, the limit cylinder 8, the rotating plate 9 and the laser lamp 10 to swing synchronously to achieve the limit The angle of the limit cylinder 8 is adjusted, and the rotation of the mounting shaft 11 will drive the ring 13 to rotate, and the ring 13 will drive the pointer 14 to swing synchronously on one side of the dial 12, so that the inclination angle of the limit cylinder 8 can be intuitively known according to the position of the pointer 14 on the dial 12, so as to effectively and accurately adjust the inclination angle of the limit cylinder 8 and realize accurate directional control of the drilling of the NPR anchor cable construction. When the inclination angle of the limit cylinder 8 is consistent with the required drilling angle of the NPR anchor cable construction, the motor 16 stops working, and then the screw rod 27 is rotated in the reverse direction, which will cause the slider 28 to move in the reverse direction. Through the sliding contact relationship between the slider 28 and the bevel 25 and the reverse force of the spring 23, the slide plate 20 drives the clamping rod 21 to move downward, so that the clamping rod 21 is inserted into the clamping groove 19, and the spherical seat 6 is locked again, and the inclination direction of the limit cylinder 8 is effectively fixed, thereby effectively performing directional operation for the drill rod drilling, thereby ensuring the directional drilling quality of the drill rod;
[0042] When the inclination angle of the control limit cylinder 8 is the same as the drilling inclination angle required for the NPR anchor cable construction, the laser lamp 10 is activated and the laser lamp 10 irradiates the surrounding rock with laser light. According to the drilling position of the NPR anchor cable construction marked on the surrounding rock by the staff, the electric push rod 2 is started, and the electric push rod 2 drives the fixed plate 3, the mounting seat 4, the spherical seat 6, the connecting rod 7, the limit cylinder 8, the rotating plate 9 and the laser lamp 10 to move horizontally synchronously, which makes the gear 1 33 move on one side of the tooth plate 1 31. Through the meshing connection relationship between the gear 1 33 and the tooth plate 1 31, the gear 1 33 is rotated, and the gear 1 33 drives the rotating rod 32 The thread block 34 rotates, and through the threaded connection relationship between the thread block 34 and the internal thread groove 35 and the sliding connection relationship between the stabilizing groove 37 and the stabilizing rod 36, the mounting seat 4 will stably move downward outside the rotating rod 32, and the mounting seat 4 will drive the mounting shaft 11, the spherical seat 6, the connecting rod 7, the limit cylinder 8, the rotating plate 9 and the laser lamp 10 to move downward synchronously, so that the limit cylinder 8, the rotating plate 9 and the laser lamp 10 move downward in the process of lateral movement, so that the laser projected by the laser lamp 10 moves on the surrounding rock. When the laser projected by the laser lamp 10 coincides with the drilling position of the NPR anchor cable construction marked on the surrounding rock, the electric push rod 2 stops working;
[0043] When the inclination angle of the limit cylinder 8 is adjusted to be in the same direction as the NPR anchor cable construction angle, the position of the laser lamp 10 is adjusted so that the laser emitted by the laser lamp 10 coincides with the marked NPR anchor cable construction position. The staff places the drill rod in the limit cylinder 8 and starts the motor 2 41. The motor 2 41 drives the gear 2 42 to rotate. Through the meshing connection between the gear 2 42 and the gear ring 40, the gear ring 40 drives the socket 39 to rotate. The socket 39 drives the arc groove 44 to rotate. Through the sliding connection between the moving rod 45 and the arc groove 44 and the strip groove 43, the moving rod 45 slides in the arc groove 44 and the strip groove 43, and the moving rod 45 passes through the groove. The mounting rod drives the clamping plates 46 to approach each other, so that the four clamping plates 46 are close to the outer wall of the drill pipe, which is convenient for the four clamping plates 46 to clamp the outer wall of the drill pipe, and the function of the ball provides convenience for the rotation and movement of the drill pipe, and effectively realizes the directional drilling of the drill pipe. As the drill pipe rotates and moves, the flip opening and closing mechanism will be activated to open one end of the limit cylinder 8, which is convenient for the drill pipe to extend to the outside of the limit cylinder 8 and drill into the marked drilling position for NPR anchor cable construction, which solves the problem of the drill pipe shaking easily during drilling and causing drilling angle deviation, realizes directional drilling of the drill pipe on the surrounding rock, effectively improves the drilling quality, and provides convenience for NPR anchor cable construction.

[0047] Combination Figure 7 and Figure 8 The difference between this embodiment and the first embodiment is that when the drilling machine drives the drill rod to move and rotate inside the limit tube 8, the movement direction of the drill rod will be consistent with the tilt direction of the limit tube 8. When one end of the drill rod contacts the side wall of the rotating plate 9 and continues to move, it will push the rotating plate 9 to move, so that the rotating plate 9 drives the telescopic groove 50 to slide outside the rotating shaft 49, and the sliding groove 52 will slide on the sliding block 51. At the same time, the rotating plate 9 will pull the tooth plate 2 58 to move through the connecting block 59 during the sliding process.

Through the clamping action of the sliding block 51 and the sliding groove 52, the rotating plate 9 is driven to rotate, which is convenient for the rotating plate 9 to disconnect the obstruction of one side of the limit cylinder 8, and it is convenient for one end of the drill rod to move out of the limit cylinder 8 and move to the marked position of the NPR anchor cable construction. With the continued movement and drilling of the drill rod, the directional drilling operation is effectively carried out on the surrounding rock, so that the design improves the drilling quality and provides convenience for the later construction of the NPR anchor cable.
