Description

Technical Field

[0001] This invention relates to the field of rock drilling devices, specifically to a sealing blasting rock drilling device capable of angle adjustment. Background Technology

[0002] In blasting projects such as mining and tunneling, it is often necessary to drill holes at specific angles and depths in the rock strata to place explosives.

[0003] CN117646597A discloses a blasting drilling device, including a support frame, which is U-shaped. The support frame is symmetrically equipped with a drilling angle adjustment transmission component, which is equipped with a drilling angle adjustment linkage component. The support frame and the drilling angle adjustment transmission component are equipped with a drilling angle adjustment support component, which is equipped with a drilling transmission component. The drilling transmission component is equipped with a blind-spot-free water spray reciprocating component, which is equipped with a jetting angle adjustment component.

[0004] The drilling equipment described above has certain shortcomings in use. When adjusting the angle, the distance between the bottom of the drill rod and the rock surface gradually increases as the rotation angle increases. The longer the drill rod, the greater this distance becomes. This leads to a significant reduction in the effective working length of the drill rod. When using drill rods that are several meters long, the effective working length can easily be shortened by tens of centimeters. This reduces the space for subsequent explosive filling, which may result in insufficient explosive filling and affect the blasting. At the same time, the increased distance between the initial position of the drill rod and the rock layer also reduces drilling efficiency. Summary of the Invention

Detailed Implementation

[0019] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0020] Example 1 This embodiment provides a technical solution: a sealing and blasting rock drilling device capable of angle adjustment, such as... Figures 1-8 As shown, it includes a self-propelled drilling assembly 1, a mounting plate 4, an angle adjustment assembly 5, and a drilling depth control frame 6.

[0021] In specific implementations, such as Figures 1-3As shown, the self-propelled drilling assembly 1 includes a drilling mechanism 2 and a drive mechanism 3. The drilling mechanism 2 includes a mounting plate 201, a drill rod 202, and a motor 203. The motor 203 is mounted on the mounting plate 201, and the drill rod 202 is mounted on the output end of the motor 203. The motor 203 can drive the drill rod 202 to rotate, enabling drilling when the drill rod 202 contacts the rock strata. The drive mechanism 3 includes a mounting housing 301, a lead screw 302, and a servo motor 303. The servo motor 303 is mounted on the top of the mounting housing 301, and the lead screw 302 is rotatably mounted inside the mounting housing 301 and mounted on the servo motor 303. At the output end of the servo motor 303, the mounting plate 201 and the lead screw 302 are connected by a connector 7. The connector 7 includes a threaded sleeve 701 and a connecting rod 702. The mounting shell 301 has a track groove 12. The threaded sleeve 701 is engaged on the lead screw 302. The connecting rod 702 is installed between the threaded sleeve 701 and the mounting plate 201 and is locked in the track groove 12. The servo motor 303 can drive the lead screw 302 to rotate, thus driving the threaded sleeve 701 and the connecting rod 702 to move along the lead screw 302, thereby driving the drilling mechanism 2 to move, and then driving the drill rod 202 to gradually drill into the rock strata.

[0022] Furthermore, the rear side of the mounting housing 301 is a removable cover, which facilitates the inspection and maintenance of internal components in the future.

[0023] In specific implementations, such as Figure 1 and Figure 2 As shown, the mounting plate 4 is used to install the self-propelled drilling assembly 1 on the engineering vehicle. The mounting plate 4 has a mounting clamp 8 for connecting with the engineering vehicle on its rear side. The mounting plate 4 has a connecting frame 9 on its front side. The mounting shell 301 has a connecting block 10 on its rear side. The connecting block 10 is mounted on the end of the connecting frame 9 through a rotating shaft 11. The connecting block 10 is rotatably connected to the connecting frame 9, so that the angle can be easily adjusted by rotation.

[0024] In specific implementations, such as Figure 1 , Figure 2 and Figure 4As shown, the angle adjustment component 5 is used to adjust the operating angle of the self-propelled drilling component 1. The angle adjustment component 5 is located at the bottom of the connecting frame 9. The angle adjustment component 5 includes a fixed plate 501, a hydraulic cylinder 502, a control rod 503, a steel ball 504, and a slider 505. The fixed plate 501 is fixedly installed at the bottom of the connecting frame 9. The hydraulic cylinder 502 is fixedly installed on one side of the fixed plate 501. The control rod 503 is installed at the output end of the hydraulic cylinder 502. The steel ball 504 is installed at the end of the control rod 503. The slider 505 is installed on the rear side of the mounting shell 301. A limit groove 13 is formed on the surface of the slider 505. A spherical track groove 14 is provided on the inner wall. The control rod 503 and the steel ball 504 are respectively locked in the limiting groove 13 and the spherical track groove 14. When adjusting the angle, the hydraulic cylinder 502 is extended. The hydraulic cylinder 502 can push the control rod 503 and the steel ball 504 outward. Therefore, the steel ball 504 can move adaptively along the spherical track groove 14. At the same time, it can push the mounting shell 301 to rotate around the rotating shaft 11 at the connection of the connecting block 10 and the connecting frame 9. Thus, the operating angle of the self-propelled drilling assembly 1 can be adjusted. The rotation angle of the self-propelled drilling assembly 1 can be adjusted by controlling the extension length of the hydraulic cylinder 502. After adjusting to the required angle, the hydraulic cylinder 502 is closed.

[0025] In specific implementations, such as Figures 5-8 As shown, the drilling depth control frame 6 is used to stabilize the self-propelled drilling assembly 1 and the mounting plate 4 and to maximize the effective working length of the drill rod 202. The drilling depth control frame 6 includes a positioning base plate 601, a side plate 602, a vertical movement component 603, and two guide plates 604. The positioning base plate 601 has a working opening corresponding to the drill rod 202. The positioning base plate 601 is attached to the rock surface to ensure the stability of the device. The side plate 602 is fixedly installed on the top side of the positioning base plate 601 and is located at the bottom of the mounting plate 4. The vertical movement component 603 is disposed between the side plate 602 and the mounting plate 4. The vertical movement component 603 is used to adaptively adjust the drill rod 202 during angle adjustment. The distance between the drill rod 202 and the bottom of the positioning is determined by two guide plates 604 installed on both sides of the side plate 602. The guide plates 604 are provided with guide grooves 15. The mounting shell 301 is equipped with a positioning rod 22 by means of a mounting block. Both ends of the positioning rod 22 are locked in the guide grooves 15. The limiting effect of the vertical moving component 603 and the guide plate 604 can make the self-propelled drilling component 1 rotate and move downward synchronously when the angle is adjusted. Therefore, it can be ensured that the bottom of the drill rod 202 is always at the same distance from the rock surface, so that the effective working length of the drill rod 202 is always at its maximum, thereby ensuring sufficient drilling depth and explosive storage space.

[0026] Furthermore, the vertical moving component 603 includes an extension plate 6031, a limiting base plate 6032, a baffle 6033, and multiple limiting springs 6034. The mounting plate 4 is hollow with an open bottom. The limiting base plate 6032 is installed at the bottom of the mounting plate 4 and has a through groove 16. The extension plate 6031 is installed on the top of the side plate 602, and the top of the extension plate 6031 passes through the through groove 16 and is disposed within the mounting plate 4. The baffle 6033 is installed on the top of the extension plate 6031 and blocks... Plate 6033 is fitted inside mounting plate 4, and multiple limiting springs 6034 are installed between baffle 6033 and the inner wall of mounting plate 4. With the above structure, when the angle is adjusted, the positioning rod 22 on the rear side of mounting shell 301 can move along guide groove 15. Therefore, the drilling mechanism 2 and mounting plate 4 move downward as a whole. Thus, extension plate 6031 can squeeze the limiting springs 6034 through baffle 6033 and shorten the distance between mounting plate 4 and side plate 602, thereby helping mounting plate 4 and self-propelled drilling assembly 1 to move vertically.

[0027] Furthermore, a reinforcing component 17 for fixing the mounting plate 4 is provided on one side of the limiting base plate 6032. The reinforcing component 17 includes an electric telescopic rod 1701 and a pressure plate 1702. The electric telescopic rod 1701 is installed on one side of the limiting base plate 6032. An expansion groove 18 is opened on one side of the inner wall of the through groove 16. The pressure plate 1702 is locked in the expansion groove 18 and is installed at the output end of the electric telescopic rod 1701. After the angle is adjusted, the electric telescopic rod 1701 is activated. The electric telescopic rod 1701 can push the pressure plate 1702 outward, thereby squeezing and fixing the extension plate 6031, thus ensuring the stability of the mounting plate 4 and the self-propelled drilling assembly 1.

[0028] In this embodiment, the equipment can be fixed to the engineering vehicle by the mounting clamp 8 for convenient transportation. When drilling is required in rock strata with an inclined angle, the hydraulic cylinder 502 is activated and extended. The extended output end of the hydraulic cylinder 502 pushes the control rod 503 and the steel ball 504 outward. Therefore, the steel ball 504 can move adaptively along the spherical track 14, and at the same time, it can push the mounting shell 301 to rotate around the rotating shaft 11 at the connection between the connecting block 10 and the connecting frame 9, thereby adjusting the operating angle of the self-propelled drilling assembly 1. The rotation angle of the self-propelled drilling assembly 1 can be adjusted by controlling the extension length of the hydraulic cylinder 502. After adjusting to the required angle, the hydraulic cylinder 502 is closed. While the self-propelled drilling assembly 1 is rotating, the positioning rod 22 can move along the guide groove 15. Therefore, the self-propelled drilling assembly 1 and the mounting plate 4 are in a downward moving state. Therefore, the extension plate 6031 can squeeze the limiting spring 6034 through the baffle 6033 and make the mounting plate 4 and the side plate 602... After the distance is shortened and the angle is adjusted, the electric telescopic rod 1701 is activated. The electric telescopic rod 1701 can push the pressure plate 1702 outward, thereby squeezing and fixing the extension plate 6031, thus ensuring the stability of the mounting plate 4 and the self-propelled drilling assembly 1. At the same time, it can ensure that the effective working length of the drill rod 202 is always at its maximum, thereby ensuring sufficient drilling depth and explosive storage space to achieve the expected blasting effect. Then, the drilling rod 202 is aligned with the drilling site by the engineering vehicle and the positioning base plate 601 is attached to the rock surface. The motor 203 and the servo motor 303 are activated. The motor 203 can drive the drill rod 202 to rotate, and the servo motor 303 can drive the lead screw 302 to rotate. Therefore, the threaded sleeve 701 and the connecting rod 702 can move along the lead screw 302, thereby driving the drilling mechanism 2 to move. When the rotating drill rod 202 contacts the rock layer during movement, it can drill the rock layer. As the drill rod 202 is fed, the drilling operation is gradually completed.

[0029] Example 2 This embodiment provides a technical solution: a sealing and blasting rock drilling device capable of angle adjustment, such as... Figures 1-9 As shown, it includes a self-propelled drilling assembly 1, a mounting plate 4, an angle adjustment assembly 5, a drilling depth control frame 6, and two sets of automatic water spraying assemblies 19.

[0030] In specific implementations, such as Figures 1-3As shown, the self-propelled drilling assembly 1 includes a drilling mechanism 2 and a drive mechanism 3. The drilling mechanism 2 includes a mounting plate 201, a drill rod 202, and a motor 203. The motor 203 is mounted on the mounting plate 201, and the drill rod 202 is mounted on the output end of the motor 203. The motor 203 can drive the drill rod 202 to rotate, enabling drilling when the drill rod 202 contacts the rock strata. The drive mechanism 3 includes a mounting housing 301, a lead screw 302, and a servo motor 303. The servo motor 303 is mounted on the top of the mounting housing 301, and the lead screw 302 is rotatably mounted inside the mounting housing 301 and mounted on the servo motor 303. At the output end of the servo motor 303, the mounting plate 201 and the lead screw 302 are connected by a connector 7. The connector 7 includes a threaded sleeve 701 and a connecting rod 702. The mounting shell 301 has a track groove 12. The threaded sleeve 701 is engaged on the lead screw 302. The connecting rod 702 is installed between the threaded sleeve 701 and the mounting plate 201 and is locked in the track groove 12. The servo motor 303 can drive the lead screw 302 to rotate, thus driving the threaded sleeve 701 and the connecting rod 702 to move along the lead screw 302, thereby driving the drilling mechanism 2 to move, and then driving the drill rod 202 to gradually drill into the rock strata.

[0031] Furthermore, the rear side of the mounting housing 301 is a removable cover, which facilitates the inspection and maintenance of internal components in the future.

[0032] In specific implementations, such as Figure 1 and Figure 2 As shown, the mounting plate 4 is used to install the self-propelled drilling assembly 1 on the engineering vehicle. The mounting plate 4 has a mounting clamp 8 for connecting with the engineering vehicle on its rear side. The mounting plate 4 has a connecting frame 9 on its front side. The mounting shell 301 has a connecting block 10 on its rear side. The connecting block 10 is mounted on the end of the connecting frame 9 through a rotating shaft 11. The connecting block 10 is rotatably connected to the connecting frame 9, so that the angle can be easily adjusted by rotation.

[0033] In specific implementations, such as Figure 1 , Figure 2 and Figure 4As shown, the angle adjustment component 5 is used to adjust the operating angle of the self-propelled drilling component 1. The angle adjustment component 5 is located at the bottom of the connecting frame 9. The angle adjustment component 5 includes a fixed plate 501, a hydraulic cylinder 502, a control rod 503, a steel ball 504, and a slider 505. The fixed plate 501 is fixedly installed at the bottom of the connecting frame 9. The hydraulic cylinder 502 is fixedly installed on one side of the fixed plate 501. The control rod 503 is installed at the output end of the hydraulic cylinder 502. The steel ball 504 is installed at the end of the control rod 503. The slider 505 is installed on the rear side of the mounting shell 301. A limit groove 13 is formed on the surface of the slider 505. A spherical track groove 14 is provided on the inner wall. The control rod 503 and the steel ball 504 are respectively locked in the limiting groove 13 and the spherical track groove 14. When adjusting the angle, the hydraulic cylinder 502 is extended. The hydraulic cylinder 502 can push the control rod 503 and the steel ball 504 outward. Therefore, the steel ball 504 can move adaptively along the spherical track groove 14. At the same time, it can push the mounting shell 301 to rotate around the rotating shaft 11 at the connection of the connecting block 10 and the connecting frame 9. Thus, the operating angle of the self-propelled drilling assembly 1 can be adjusted. The rotation angle of the self-propelled drilling assembly 1 can be adjusted by controlling the extension length of the hydraulic cylinder 502. After adjusting to the required angle, the hydraulic cylinder 502 is closed.

[0034] In specific implementations, such as Figures 5-8 As shown, the drilling depth control frame 6 is used to stabilize the self-propelled drilling assembly 1 and the mounting plate 4 and to maximize the effective working length of the drill rod 202.

The side plate 602 is fixedly installed on the top side of the positioning base plate 601 and is located at the bottom of the mounting plate 4. The vertical movement component 603 is disposed between the side plate 602 and the mounting plate 4. The vertical movement component 603 is used to adaptively adjust the drill rod 202 during angle adjustment. The distance between the drill rod 202 and the bottom of the positioning is determined by two guide plates 604 installed on both sides of the side plate 602. The guide plates 604 are provided with guide grooves 15. The mounting shell 301 is equipped with a positioning rod 22 by means of a mounting block. Both ends of the positioning rod 22 are locked in the guide grooves 15. The limiting effect of the vertical moving component 603 and the guide plate 604 can make the self-propelled drilling component 1 rotate and move downward synchronously when the angle is adjusted. Therefore, it can be ensured that the bottom of the drill rod 202 is always at the same distance from the rock surface, so that the effective working length of the drill rod 202 is always at its maximum, thereby ensuring sufficient drilling depth and explosive storage space.

[0035] Furthermore, the vertical moving component 603 includes an extension plate 6031, a limiting base plate 6032, a baffle 6033, and multiple limiting springs 6034. The mounting plate 4 is hollow with an open bottom. The limiting base plate 6032 is installed at the bottom of the mounting plate 4 and has a through groove 16. The extension plate 6031 is installed on the top of the side plate 602, and the top of the extension plate 6031 passes through the through groove 16 and is disposed within the mounting plate 4. The baffle 6033 is installed on the top of the extension plate 6031 and blocks... Plate 6033 is fitted inside mounting plate 4, and multiple limiting springs 6034 are installed between baffle 6033 and the inner wall of mounting plate 4. With the above structure, when the angle is adjusted, the positioning rod 22 on the rear side of mounting shell 301 can move along guide groove 15. Therefore, the drilling mechanism 2 and mounting plate 4 move downward as a whole. Thus, extension plate 6031 can squeeze the limiting springs 6034 through baffle 6033 and shorten the distance between mounting plate 4 and side plate 602, thereby helping mounting plate 4 and self-propelled drilling assembly 1 to move vertically.

[0036] Furthermore, a reinforcing component 17 for fixing the mounting plate 4 is provided on one side of the limiting base plate 6032. The reinforcing component 17 includes an electric telescopic rod 1701 and a pressure plate 1702. The electric telescopic rod 1701 is installed on one side of the limiting base plate 6032. An expansion groove 18 is opened on one side of the inner wall of the through groove 16. The pressure plate 1702 is locked in the expansion groove 18 and is installed at the output end of the electric telescopic rod 1701. After the angle is adjusted, the electric telescopic rod 1701 is activated. The electric telescopic rod 1701 can push the pressure plate 1702 outward, thereby squeezing and fixing the extension plate 6031, thus ensuring the stability of the mounting plate 4 and the self-propelled drilling assembly 1.

[0037] In specific implementations, such as Figure 1 and Figure 9As shown, the positioning base plate 601 is equipped with two sets of automatic water spraying components 19 for spraying water at the drill hole. The two sets of automatic water spraying components 19 are located on both sides of the drill rod 202.
