Description

Technical Field

[0001] This invention relates to the field of pre-splitting hole drilling technology, and in particular to a pre-splitting hole angle control device. Background Technology

[0002] Pre-splitting holes are a core element of pre-splitting blasting technology. They refer to a set of parallel blast holes drilled along the excavation outline before the main blasting zone. Precise blasting creates a smooth pre-splitting surface to protect and preserve the stability of the rock mass or slope. Pre-splitting blasting technology is widely used in slope and tunnel engineering. The angular accuracy of the pre-splitting holes directly affects the pre-splitting effect. When drilling pre-splitting holes, an angle control device is usually required to control the drilling angle of the drilling rig.

[0003] Existing drilling rig angle control devices typically adjust the drilling rig angle using cylinders. However, the high-frequency, high-energy, and impactful vibrations generated during drilling can easily cause the cylinders to loosen or become damaged, leading to a deviation in the drilling rig angle. Furthermore, the vibrations can easily cause the device itself to move, resulting in a shift in the drilling rig's position and affecting drilling accuracy.

[0004] Therefore, a pre-splitting hole angle control device has now been developed that can lock the drilling angle and position during drilling to avoid vibration affecting drilling accuracy. Summary of the Invention

[0005] To overcome the shortcomings of existing drilling rig angle control devices, which generate high-frequency, high-energy, and impactful vibrations during drilling, easily causing cylinder loosening or damage, leading to drilling angle deviation, and causing the device body to move, resulting in drilling position deviation and affecting drilling accuracy, this invention provides a pre-splitting hole angle control device that can lock the drilling angle and position during drilling to avoid vibration affecting drilling accuracy.

[0006] Technical solution:

[0007] A pre-splitting hole angle control device includes a vehicle body, an adjusting frame, a first docking frame, a moving frame, a first connecting rod, a cylinder, a drilling component, a locking component, and a stabilizing component. The adjusting frame is rotatably connected to the upper right side of the vehicle body, and the first docking frame is connected to the upper side of the adjusting frame. The moving frame is slidably connected to the upper part of the vehicle body. Two first connecting rods are rotatably connected between the moving frame and the adjusting frame. Cylinders are connected to both the front and rear sides of the upper part of the vehicle body, and the telescopic ends of the cylinders are connected to the moving frame. The first docking frame is equipped with a drilling component capable of drilling pre-splitting holes. The moving frame is equipped with a locking component capable of automatically locking its position. The adjusting frame is equipped with a stabilizing component capable of locking the position of the vehicle body.

[0008] Furthermore, it is particularly preferred that the drilling assembly includes a propulsion device, a second docking frame, a drilling rig, a drill rod, and fixing screws. The second docking frame is detachably connected to the upper side of the first docking frame via multiple fixing screws. The propulsion device is connected to the upper side of the second docking frame. The drilling rig is mounted on the propulsion device, and a drill rod is mounted on the left side of the drilling rig. When the cylinder is activated, the moving frame is moved to the left, and the adjusting frame is rotated upward through the first connecting rod, thereby driving the drilling rig to rotate. The angle of the drilling rig is adjusted according to the drilling requirements of the pre-splitting hole. After adjustment, the drilling rig is moved to the left by the propulsion device, so that the drill rod drills into the construction area to create a pre-splitting hole.

[0009] Furthermore, it is particularly preferred that the device also includes an auxiliary frame, with the left side of the propulsion device connected to the auxiliary frame, through which the drill rod passes.

[0010] Furthermore, preferably, the locking assembly includes a first locking frame, a torsion spring, a motor, a bidirectional lead screw, and a limiting frame. The first locking frames are rotatably connected to both the front and rear sides of the moving frame. Multiple torsion springs connect the first locking frames to the moving frame. A motor is connected to the upper right front side of the vehicle body. A bidirectional lead screw is connected to the output shaft of the motor. The bidirectional lead screw is rotatably connected to the vehicle body. Limiting frames are threadedly connected to both the front and rear ends of the bidirectional lead screw. The limiting frames are slidably connected to the vehicle body. Each limiting frame engages with an adjacent first locking frame. When the moving frame moves, it drives the first locking frames to move. When the moving frame reaches the designated position, the motor is started, driving the bidirectional lead screw to rotate, causing the limiting frames to move closer together. Under the force of the torsion springs, the first locking frames engage with the limiting frames, preventing the first locking frames from moving to the right, thus locking the first locking frames in one direction.

[0011] Furthermore, it is particularly preferred that the stabilizing component includes a second link, a nail plate, and a sliding frame. The lower side of the middle of the adjusting frame is rotatably connected to two front and rear second links, both of which are movably connected to the vehicle body. The nail plate is slidably connected to the lower part of the vehicle body, and the upper sides of the nail plate are slidably connected to the front and rear sides of the nail plate. The sliding frames are rotatably connected to the adjacent second links. When the adjusting frame rotates upward, it pushes the sliding frames to move through the second links, causing the nail plate to move downward and insert into the ground, locking the position of the vehicle body.

[0012] In addition, it is particularly preferred that the device also includes a friction plate, with a friction plate connected to the middle of each limiting frame.

[0013] Furthermore, it is particularly preferred that the friction plates are provided with rubber on the side where they are close to each other.

[0014] In addition, it is particularly preferred that a warning component is included, which includes a pressure sensor and a pressure alarm. Multiple pressure sensors are connected to each limit frame, and pressure alarms are connected to the left side of each limit frame that is far apart from each other. When the drilling rig vibrates, the vibration is transmitted to the first clamping frame, and the pressure applied by the first clamping frame to the pressure sensor increases. When the pressure exceeds the specified range, the pressure alarm sounds an alarm.

[0015] Furthermore, it is particularly preferred that the vehicle body, cylinders, motors, pressure sensors, pressure alarms, propulsion devices, drilling rigs, and processors are electrically connected via a control module.

[0016] Furthermore, it is particularly preferred that the assembly also includes a locking component, which includes a second locking bracket, a spring, and a trigger plate. The second locking bracket is slidably connected to both the front and rear sides of the first docking bracket. Each second locking bracket engages with an adjacent fixing screw. Multiple springs connect the second locking bracket to the first docking bracket. Initially, the springs are in a compressed state. Trigger plates are connected to the upper sides of both the front and rear of the vehicle body. The trigger plates engage with the second locking brackets. When the adjusting bracket rotates upward, it drives the second locking brackets to move upward, causing the second locking brackets to disengage from the trigger plates. Subsequently, the springs rebound, causing the second locking brackets to move inward and engage with the fixing screws, thus locking the fixing screws.

[0017] Compared with the prior art, the present invention has the following advantages: 1. The present invention starts the motor and drives the bidirectional lead screw to rotate, so that the limit frames move closer to each other. Under the action of the torsion spring, the first locking frame and the limit frame are locked together, preventing the first locking frame from moving to the right and locking the first locking frame in one direction. In turn, the moving frame, the first connecting rod and the adjusting frame are locked, which achieves the effect of avoiding damage to the cylinder when the drilling machine vibrates and avoiding affecting the drilling accuracy.

[0018] 2. In this invention, when the adjusting frame rotates upward, the sliding frame is pushed to move through the second connecting rod, causing the nail plate to move downward and insert into the ground, locking the position of the vehicle body. This achieves the effect of preventing the vehicle body from moving due to the vibration of the drilling machine and ensuring drilling accuracy.

[0019] 3. The present invention, by bringing the limiting frames closer together, causes the friction plates to move closer together, so that the friction plates come into contact with the nail plates and restrict the nail plates, thereby achieving the effect of further improving the stability of the vehicle body.

[0020] 4. When the drilling rig vibrates, the vibration is transmitted to the first clamping frame, and the pressure applied by the first clamping frame to the pressure sensor increases. When the pressure exceeds the specified range, the pressure alarm sounds to remind the staff to make timely adjustments.

[0021] 5. When the adjusting frame rotates upward, it drives the second locking frame to move upward, causing the second locking frame to disengage from the trigger plate. Then, the spring rebounds, causing the second locking frame to move inward and engage with the fixing screw, thus locking the fixing screw. This achieves the effect of preventing the fixing screw from loosening due to vibration and ensuring the stability of the drilling rig installation. Attached Figure Description

[0030] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0031] A pre-cracked hole angle control device, such as Figures 1-7As shown, it includes a vehicle body 1, an adjusting frame 2, a first docking frame 3, a moving frame 4, a first connecting rod 5, a cylinder 6, a drilling component, a locking component, and a stabilizing component. The adjusting frame 2 is rotatably connected to the upper right side of the vehicle body 1, and the first docking frame 3 is connected to the upper side of the adjusting frame 2. The moving frame 4 is slidably connected to the upper part of the vehicle body 1. The moving frame 4 and the adjusting frame 2 are rotatably connected by two first connecting rods 5. The upper front and rear sides of the vehicle body 1 are connected to cylinders 6, and the telescopic ends of the cylinders 6 are connected to the moving frame 4. The drilling component is provided on the first docking frame 3, the locking component is provided on the moving frame 4, and the stabilizing component is provided on the adjusting frame 2.

[0032] like Figure 1 and Figure 4 As shown, the drilling assembly includes a propulsion device 13, a second docking frame 14, a drilling rig 15, a drill rod 16, an auxiliary frame 17, and fixing screws 18. The second docking frame 14 is detachably connected to the upper side of the first docking frame 3 by four fixing screws 18. The propulsion device 13 is connected to the upper side of the second docking frame 14. The drilling rig 15 is mounted on the propulsion device 13. The drill rod 16 is mounted on the left side of the drilling rig 15. The auxiliary frame 17 is connected to the left side of the propulsion device 13. The drill rod 16 passes through the auxiliary frame 17.

[0033] like Figure 1 and Figure 2 As shown, the locking assembly includes a first locking frame 7, a torsion spring 8, a motor 9, a bidirectional lead screw 10, and a limiting frame 11. The first locking frame 7 is rotatably connected to both the front and rear sides of the movable frame 4. Two torsion springs 8 are connected between each first locking frame 7 and the movable frame 4. The motor 9 is connected to the front right side of the vehicle body 1. The bidirectional lead screw 10 is connected to the output shaft of the motor 9. The bidirectional lead screw 10 is rotatably connected to the vehicle body 1. The limiting frame 11 is threadedly connected to both the front and rear sides of the bidirectional lead screw 10. The limiting frame 11 is slidably connected to the vehicle body 1. The limiting frame 11 is engaged with the adjacent first locking frame 7.

[0034] like Figure 1 and Figure 6 As shown, the stabilizing assembly includes a friction plate 111, a second connecting rod 22, a nail plate 23, and a sliding frame 24. The middle of the limiting frame 11 is connected to the friction plate 111. Rubber is provided on the side of the friction plates 111 that are close to each other to facilitate the restriction of the nail plate 23. The lower side of the middle of the adjusting frame 2 is rotatably connected to two front and rear second connecting rods 22. The second connecting rods 22 are movably connected to the vehicle body 1. The lower part of the vehicle body 1 is slidably connected to the nail plate 23. The upper sides of the front and rear parts of the nail plate 23 are slidably connected to the sliding frame 24. The sliding frame 24 is rotatably connected to the adjacent second connecting rod 22.

[0035] When using this invention, firstly, the second docking frame 14 is installed on the first docking frame 3 using fixing screws 18. Then, the propulsion device 13 and the drilling rig 15 are installed on the first docking frame 3. After installation, the vehicle body 1 is moved to the pre-splitting hole drilling area. The processor starts the cylinder 6 through the control module, pushing the moving frame 4 to move to the left. The first connecting rod 5 pushes the adjusting frame 2 to rotate upward, thereby pushing the drilling rig 15 to rotate. According to the drilling requirements of the pre-splitting hole, the angle of the drilling rig 15 is adjusted. After adjustment, the propulsion device 13 pushes the drilling rig 15 to move to the left, so that the drill rod 16 drills into the construction area to create a pre-splitting hole. When the drill rod 16 drills, it passes through the auxiliary frame 17. The auxiliary frame 17 guides the drill rod 16 to prevent it from deviating. After drilling is completed, the drilling rig 15 and the drill rod 16 are reset. Then, the cylinder 6 is started in the opposite direction, so that the moving frame 4 moves to the right and resets, so that the first connecting rod 5 and the adjusting frame 2 rotate to a horizontal state, which facilitates subsequent transfer to other construction areas.

[0036] When the moving frame 4 moves, it drives the first locking frame 7 to move. When the moving frame 4 reaches the designated position, the processor starts the motor 9 through the control module, which drives the bidirectional lead screw 10 to rotate, causing the limiting frames 11 to move closer to each other. Under the force of the torsion spring 8, the first locking frame 7 and the limiting frame 11 are engaged, preventing the first locking frame 7 from moving to the right and locking the first locking frame 7 in one direction. This locks the moving frame 4, the first connecting rod 5, and the adjusting frame 2, thereby preventing damage to the cylinder 6 when the drilling machine 15 vibrates and avoiding affecting the drilling accuracy. After drilling is completed, the motor 9 is started in reverse, which drives the bidirectional lead screw 10 to rotate, causing the limiting frames 11 to move away from each other and disengage from the first locking frame 7, thus preventing the moving frame 4 from moving to the right and resetting.

[0037] When the adjusting frame 2 rotates upward, it pushes the sliding frame 24 to move through the second connecting rod 22, causing the nail plate 23 to move downward and insert into the ground, locking the position of the vehicle body 1. This prevents the vehicle body 1 from moving due to the vibration of the drilling rig 15, ensuring drilling accuracy. As the limiting frames 11 move closer to each other, they also drive the friction plates 111 to move closer to each other, so that the friction plates 111 contact the nail plate 23, restricting the nail plate 23 and further improving the stability of the vehicle body 1. After the adjusting frame 2 is reset, it drives the nail plate 23 to move upward and lift off the ground through the second connecting rod 22, making it easier for the vehicle body 1 to move.

[0038] like Figures 1-3 As shown, it also includes a warning component, which includes a pressure sensor 110 and a pressure alarm 12. Multiple pressure sensors 110 are connected to each limit frame 11, and pressure alarms 12 are connected to each side of the left side of the limit frame 11 that are far apart from each other. The vehicle body 1, cylinder 6, motor 9, pressure sensor 110, pressure alarm 12, propulsion device 13, drilling rig 15 and processor are electrically connected through a control module.

[0039] The first positioning frame 7 is in contact with the pressure sensor 110. When the drilling rig 15 vibrates, the vibration is transmitted to the first positioning frame 7, and the pressure applied by the first positioning frame 7 to the pressure sensor 110 increases. When the pressure exceeds the specified range, the pressure alarm 12 sounds an alarm to remind the staff to make timely adjustments.

[0040] like Figure 1 and Figure 5 As shown, it also includes a positioning assembly, which includes a second positioning frame 19, a spring 20 and a trigger plate 21. The second positioning frame 19 is slidably connected to both the front and rear sides of the first docking frame 3. The second positioning frame 19 is engaged with the adjacent fixing screw 18. Two springs 20 are connected between the second positioning frame 19 and the first docking frame 3. Initially, the springs 20 are in a compressed state. The trigger plates 21 are connected to the upper sides of both the front and rear parts of the vehicle body 1. The trigger plates 21 are pressed against the second positioning frame 19.

[0041] When the adjusting frame 2 rotates upward, it drives the second locking frame 19 to move upward, causing the second locking frame 19 to disengage from the trigger plate 21. Then, the spring 20 rebounds, causing the second locking frame 19 to move inward and engage with the fixing screw 18, locking the fixing screw 18 and preventing it from loosening due to vibration, thus ensuring the stability of the drilling rig 15 installation. After the adjusting frame 2 resets, the trigger plate 21 presses the second locking frame 19 outward to disengage from the fixing screw 18.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
