Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, specifically a drilling method for drill rods on a three-arm rock drilling rig for geological exploration. Background Technology

[0002] A three-arm rock drilling rig is a type of rock drilling equipment used in tunnel and underground engineering projects employing the drill-and-blast method. It can move and support multiple rock drills simultaneously for drilling operations. It mainly consists of a rock drill, drill arms, a steel frame, a traveling mechanism, and other necessary auxiliary equipment, as well as additional equipment added according to project requirements.

[0003] A Chinese patent with publication number CN209637764U discloses a stabilizing frame for a three-arm rock drilling rig, including a frame body and fixing devices mounted on the frame body for stabilizing both sides of the three-arm rock drilling rig. A traveling mechanism is provided below the frame body. The frame body is U-shaped and includes two columns and a connecting frame for connecting the two columns. The two columns are symmetrically arranged with respect to the centerline of the tunnel cross-section. Using this device, the three-arm rock drilling rig can be stabilized during construction, improving construction quality. At the same time, this device is easy to obtain and inexpensive, and can move with the rig, improving construction efficiency.

[0004] When drilling in geological exploration, some rocks may break off from the surrounding rock during the drilling process. Some of these rocks have a large impact force and may affect the workers, resulting in low safety.

[0005] Therefore, the present invention provides a method for drilling the drill rod of a three-arm rock drilling rig for geological exploration. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is: a drilling method for drill rods of a three-arm rock drilling rig for geological exploration, comprising the following steps:

[0008] S1. The external drive drives the booms at different locations on the surface of the rock drilling rig to rotate to the appropriate position, and the external drive controls the drill rod on its surface to drill the surrounding rock.

[0009] S2, and the external drive simultaneously drives the threaded column to rotate, which in turn drives the threaded sleeve that meshes with it to move upward, and the threaded sleeve drives the rotating rods on the left and right sides to rotate.

[0010] S3. Rotate the rotating rod to drive the stop at the other end to rotate. Then the stops on both sides open and are placed on both sides of the drill rod in a 'V' shape.

[0011] Preferably, an arm is rotatably connected to the outer surface of the rock drilling rig body, a support base is fixedly connected to the outer surface of the arm, a threaded column is rotatably connected inside the support base, a threaded sleeve is engaged with the outer surface of the threaded column, rotating rods are rotatably connected to both sides of the threaded sleeve, and stop seats are rotatably connected to both sides of the support base. One end of each rotating rod is connected to the side surface of the stop seat, and the other end is connected to the outer surface of the threaded sleeve. In this embodiment, one end of the threaded column is connected to an external motor, and the connection method is existing technology and will not be described in detail. During operation, when this three-arm rock drilling rig is not in use, the stop seats and rotating rods are in a retracted state, which can save space. The three-arm rock drill utilizes space effectively. When the drill rod drills into the geology, the external drive simultaneously rotates the threaded column, which in turn moves the threaded sleeve that meshes with it upwards. The threaded sleeve then rotates the rotating rods on both sides, causing the rotating rods to rotate the stop seats on the other end. The stop seats then open and are positioned in a 'V' shape on both sides of the drill rod, effectively shielding the drill rod from flying debris during drilling and preventing it from affecting the workers. This design allows for efficient use of space and enhances safety. Since this three-arm rock drill has three arms that drill into different areas of the surrounding rock, these stop seats improve the safety of the drill rod during drilling.

[0012] Preferably, a pressure plate is rotatably connected to the surface of each stop seat, and there are two pressure plates inside each stop seat, arranged symmetrically from left to right. A pressure-resistant inclined rod is rotatably connected to the lower surface of the pressure plate inside the stop seat. The bottom of the pressure-resistant inclined rod is rotatably connected to the inside of the stop seat via a rotating shaft. A compression spring is fixedly connected inside the pressure-resistant inclined rod. During operation, when debris is ejected during drilling, some of the debris will impact the pressure plate on the surface of the stop seat. When the impact force of the debris is greater than the elastic force of the compression spring, and because the surface of the pressure plate is rotatably connected to the surface of the stop seat, the impact force of the debris will cause the pressure plate to drive the pressure-resistant inclined rod and the compression spring to rotate, thereby buffering the impact force of the debris and reducing the possibility of some debris entering the connection between the drill arm support and the frame.

[0013] Preferably, a turntable is fixedly connected to the outer surface of the stop, and a deflection rod is rotatably connected to the outer surface of the turntable via a rotating shaft. A top rod is rotatably connected to the side of the deflection rod closest to the pressure plate, and the bottom end of the top rod is connected to the upper surface of the pressure plate. A piston rod is fixedly connected to the side of the deflection rod away from the top rod, and one end of the piston rod penetrates the interior of the slurry storage tank. A slurry outlet pipe is fixedly connected to the outer surface of the slurry storage tank. During operation, when the pressure plate presses down on the inclined rod to rotate, the pressure plate simultaneously pulls the top rod on its surface, causing the top rod to pull the deflection rod at its upper end. This causes the deflection rod to rotate at a certain angle inside the turntable, and then the deflection rod presses against the piston rod on one side, causing the piston rod to squeeze the slurry inside the slurry storage tank and spray it from the slurry outlet pipe onto one side of the drill rod. This allows the slurry to not only remove slag but also clean the borehole, reducing the wear rate of the drill rod.

[0014] Preferably, a compression spring is fitted onto the outer surface of the piston rod; and the elastic potential energy of the compression spring is less than that of the compression spring. During operation, when the pressure plate is not subjected to the impact force of the crushed stone, the compression spring will cause the pressure plate to reset under its own force. In turn, the pressure plate will cause the push rod and the deflection rod to reset, causing the deflection rod to drive the piston rod to reset. Since the elastic potential energy of the compression spring is less than that of the compression spring, the deflection rod will pull the piston rod and the compression spring into a stretched state when resetting. Afterwards, when the compression spring returns from the stretched state to the initial state, it will drive the piston rod again to push the slurry inside the slurry tank, further causing the slurry to be sprayed onto the surface of the drill rod.

[0015] Preferably, a first contact point is fixedly connected to the outer surface of the deflection rod, and a second contact point is fixedly connected to the inside of the turntable. During operation, when the impact force of the crushed rock on the pressure plate is large, the rotation angle of the pressure plate driving the anti-pressure inclined rod and the compression spring will increase, causing the pressure plate to move the top rod a greater distance. This results in a larger rotation angle of the deflection rod, causing the first contact point on the surface of the deflection rod to contact the second contact point inside the turntable. At this time, the external circuit is connected, allowing the controller to record the location of the surrounding rock. Since this three-arm rock drill has three arms, and the three arms drill different parts of the surrounding rock, the impact force of the crushed rock generated during drilling at different locations varies, which will affect whether the first and second contact points of different arms are in contact. This allows for timely judgment of different levels of surrounding rock quality, and the controller can determine the level of the surrounding rock, bringing convenience to geological exploration.

[0016] Preferably, an inclined column is rotatably connected to the front of the boom, and a pressure rod is fixedly connected to the upper surface of the inclined column. The top end of the pressure rod is connected to the upper surface of the pressure plate. During operation, when the pressure plate rotates, the pressure plate will simultaneously press the pressure rod, causing the pressure rod to drive the inclined column to rotate, thereby causing some of the gravel falling onto the side surface of the pressure rod to fall off, thus avoiding the phenomenon of excessive gravel accumulation affecting the use of the drill rod itself.

[0017] Preferably, the outer surface of the inclined column is provided with a groove, and a counterweight is slidably connected to the outer surface of the inclined column and inside the groove. There are two counterweights, and the outer surface of the counterweight is provided with a groove. During operation, since the counterweight is slidably connected to the outer surface of the inclined column, when the inclined column rotates, the counterweight will slide in the direction of the inclined column, which can easily push away the gravel on the surface of the inclined column, making it more convenient to use.

[0018] Preferably, an oil reservoir is fixedly connected to one side of the support base, and a pressure column is slidably connected inside the oil reservoir. The top of the pressure column is connected to the lower surface of the stop, and a piston plate is fixedly connected to the bottom of the pressure column inside the oil reservoir. An oil outlet pipe is fixedly connected to the lower surface of the oil reservoir. During operation, when the stop on the surface of the support base rotates, the stop will simultaneously drive the pressure column on its surface to move. Then, the pressure column moves inside the oil reservoir and applies pressure to the lubricating oil inside the oil reservoir. This causes the lubricating oil inside the oil reservoir to flow through the oil outlet pipe to one side of the threaded column and drill rod, lubricating the threaded column and drill rod and reducing the problem of excessive dust entering the threaded column and drill rod, which leads to high friction during rotation.

[0019] Preferably, an oil outlet film is installed on the outer surface of the oil outlet pipe, the length of the oil outlet film is greater than the length of the oil outlet pipe, and an oil outlet hole is opened on the surface of the oil outlet film; when the lubricating oil inside the oil storage tank is squeezed, the lubricating oil will simultaneously squeeze the oil outlet film at one end of the oil outlet pipe, making the diameter of the oil outlet hole on the surface of the oil outlet film larger, thereby controlling the oil output to a certain extent and making it more convenient to use.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The drilling method of a three-arm rock drilling rig for geological exploration described in this invention involves rotating the rotating rods on both sides via a threaded sleeve. This rotating rods then rotate the stop seats at the other end, causing the stop seats on both sides to open and be positioned in a 'V' shape on both sides of the drill rod. This effectively shields the drill rod from flying debris during drilling, preventing it from affecting the workers. It also allows for efficient use of space and enhances safety. Since this three-arm rock drilling rig has three arms that drill at different locations in the surrounding rock, these stop seats improve the safety of the drill rod during drilling.

[0022] 2. The drilling method of a three-arm drilling rig for geological exploration described in this invention involves a pressure plate pulling a top rod on its surface, which in turn pulls a deflection rod at its upper end. This causes the deflection rod to rotate at a certain angle inside the turntable, thereby pressing against a piston rod on one side. This causes the piston rod to squeeze the slurry inside the slurry storage tank and spray it from the slurry outlet pipe onto one side of the drill rod. This allows the slurry to not only remove slag but also clean the borehole, reducing the wear rate of the drill rod.

[0023] 3. The drilling method of the three-arm rock drilling rig for geological exploration described in this invention involves the first contact point on the surface of the deflection rod contacting the second contact point inside the turntable. At this time, the external circuit is connected, causing the controller to record the surrounding rock at this location. Since this three-arm rock drilling rig has three arms, and the three arms drill different parts of the surrounding rock, the impact force generated by the extruded rock fragments during the drilling process varies, which will cause the first and second contact points of different arms to contact. This allows for timely judgment of different levels of surrounding rock quality, and the controller determines the level of the surrounding rock, bringing convenience to geological exploration.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figure 8 As shown in the embodiment of the present invention, a drilling method for a drill rod of a three-arm rock drilling rig for geological exploration includes the following steps:

[0037] S1. The external drive drives the boom 2 at different locations on the surface of the rock drilling rig body 1 to rotate to a suitable position, and the external drive controls the drill rod on its surface to drill the surrounding rock.

[0038] S2. Simultaneously, the external drive causes the threaded column 4 to rotate, and the threaded column 4 will simultaneously drive the threaded sleeve 41 that meshes with it to move upward. The threaded sleeve 41 drives the rotating rods 42 on the left and right sides to rotate.

[0039] S3. The rotating rod 42 drives the stop 43 at the other end to rotate. Then the stop 43 on both sides opens and is placed on both sides of the drill rod in a 'V' shape.

[0040] like Figures 1 to 6As shown, the outer surface of the rock drilling rig body 1 is rotatably connected to the boom 2, and the outer surface of the boom 2 is fixedly connected to the support base 3. A threaded column 4 is rotatably connected inside the support base 3, and a threaded sleeve 41 is meshed with the outer surface of the threaded column 4. Rotating rods 42 are rotatably connected to both sides of the threaded sleeve 41, and stop seats 43 are rotatably connected to both sides of the support base 3. One end of each rotating rod 42 is connected to the side surface of the stop seat 43, and the other end is connected to the outer surface of the threaded sleeve 41. In this embodiment, one end of the threaded column 4 is connected to an external motor, and the connection method is existing technology and will not be elaborated further. When using the drill arm for drilling in geological exploration, some rock fragments may break out from the surrounding rock during the drilling process, and some of these fragments have a large impact force. Some of the broken rock fragments may affect the workers, resulting in low safety. When the three-arm rock drill is not in use, the stop 43 and the rotating rod 42 are in a retracted state, saving space. When the three-arm rock drill drills the geology through the drill rod, the external drive simultaneously rotates the threaded column 4, which in turn drives the threaded sleeve 41 that meshes with it to move upward. The threaded sleeve 41 drives the rotating rods 42 on both sides to rotate, causing the rotating rods 42 to drive the stop 43 at the other end to rotate. Then the stop 43 on both sides opens and is placed on both sides of the drill rod in a 'V' shape, which can shield the debris splashed out by the drill rod during drilling, preventing the debris from affecting the workers. It can make reasonable use of the placement space and is safer to use. Since this three-arm rock drill has three arms 2, and the three arms 2 drill different parts of the surrounding rock, the stop 43 can improve the safety of the drill rod during the drilling process.

[0041] like Figures 2 to 3 As shown, a pressure plate 5 is rotatably connected to the surface of a single stop 43. There are two pressure plates 5 inside a single stop 43, arranged symmetrically from left to right. A pressure-resistant inclined rod 51 is rotatably connected to the lower surface of the pressure plate 5 inside the stop 43. The bottom of the pressure-resistant inclined rod 51 is rotatably connected to the inside of the stop 43 via a rotating shaft. A compression spring 52 is fixedly connected inside the pressure-resistant inclined rod 51. During operation, when debris is ejected during drilling, some of the debris will impact the pressure plate 5 on the surface of the stop 43. When the impact force of the debris is greater than the elastic force of the compression spring 52, and because the surface of the pressure plate 5 is rotatably connected to the surface of the stop 43, the impact force of the debris will cause the pressure plate 5 to drive the pressure-resistant inclined rod 51 and the compression spring 52 to rotate, thereby buffering the impact force of the debris and reducing the possibility of some debris entering the connection between the drill arm support and the frame.

[0042] like Figures 2 to 5As shown, a turntable 6 is fixedly connected to the outer surface of the baffle 43. A deflection rod 61 is rotatably connected to the outer surface of the turntable 6 via a rotating shaft. A top rod 62 is rotatably connected to the side of the deflection rod 61 near the pressure plate 5. The bottom end of the top rod 62 is connected to the upper surface of the pressure plate 5. A piston rod 63 is fixedly connected to the side of the deflection rod 61 away from the top rod 62. One end of the piston rod 63 penetrates the interior of the slurry storage tank 64. A slurry outlet pipe 65 is fixedly connected to the outer surface of the slurry storage tank 64. During operation, when the pressure plate 5 presses down on the inclined rod 51 and rotates, the pressure plate 5 will simultaneously pull the top rod 62 on its surface, causing the top rod 62 to pull the deflection rod 61 at its upper end. This causes the deflection rod 61 to rotate at a certain angle inside the turntable 6. Consequently, the deflection rod 61 will press against the piston rod 63 on one side, causing the piston rod 63 to squeeze the slurry inside the slurry storage tank 64 and spray it from the slurry outlet pipe 65 onto one side of the drill rod. This allows the slurry to not only remove slag but also clean the borehole, reducing the wear rate of the drill rod.

[0043] like Figures 2 to 5 As shown, a compression spring 631 is sleeved on the outer surface of the piston rod 63; and the elastic potential energy of the compression spring 631 is less than that of the compression spring 52. During operation, when the pressure plate 5 is not subjected to the impact force of the crushed stone, the pressure plate 5 will be reset under the return of the compression spring 52. Then, the pressure plate 5 will drive the top rod 62 and the deflection rod 61 to return, so that the deflection rod 61 drives the piston rod 63 to reset. Since the elastic potential energy of the compression spring 631 is less than that of the compression spring 52, the deflection rod 61 will pull the piston rod 63 and the compression spring 631 into a stretched state when resetting. Afterwards, when the compression spring 631 returns from the stretched state to the initial state, it will drive the piston rod 63 again to push the slurry inside the slurry tank 64, and further spray the slurry onto the surface of the drill rod.

[0044] like Figures 5 to 6 As shown, the outer surface of the deflection rod 61 is fixedly connected to a first contact point 611, and the inside of the turntable 6 is fixedly connected to a second contact point 612. During operation, when the impact force of the crushed stone on the pressure plate 5 is large, the rotation angle of the pressure plate 5 driving the pressure rod 51 and the compression spring 52 will increase, causing the pressure plate 5 to drive the top rod 62 to move a greater distance, thus increasing the rotation angle of the deflection rod 61. This causes the first contact point 611 on the surface of the deflection rod 61 to contact the second contact point 612 inside the turntable 6. At this time, the external circuit is connected, allowing the controller to record the surrounding rock at this location. Since this three-arm rock drill has three arms 2, and the three arms 2 drill at different locations of surrounding rock, the impact force of the crushed stone generated during drilling at different locations will vary, thus affecting whether the first contact point 611 and the second contact point 612 of different arms 2 are in contact. This allows for timely judgment of different levels of surrounding rock quality, and the controller determines the level of surrounding rock, bringing convenience to geological exploration.

[0045] like Figures 3 to 4 As shown, an inclined column 7 is rotatably connected to the front of the boom 2. A pressure rod 71 is fixedly connected to the upper surface of the inclined column 7. The top end of the pressure rod 71 is connected to the upper surface of the pressure plate 5. During operation, when the pressure plate 5 rotates, it will simultaneously press the pressure rod 71, causing the pressure rod 71 to drive the inclined column 7 to rotate. This causes some of the gravel falling onto the side surface of the pressure rod 71 to fall off, preventing the accumulation of gravel from affecting the use of the drill rod itself.

[0046] like Figures 3 to 4 As shown, the outer surface of the inclined column 7 is provided with a groove, and a counterweight 72 is slidably connected to the outer surface of the inclined column 7 and inside the groove. There are two counterweights 72, and the outer surface of the counterweights 72 is provided with a groove. During operation, since the counterweights 72 are slidably connected to the outer surface of the inclined column 7, when the inclined column 7 rotates, the counterweights 72 will slide in the direction of inclination of the inclined column 7, which can conveniently push away the gravel on the surface of the inclined column 7, making it convenient to use.

[0047] Example 2

[0048] like Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: an oil reservoir 8 is fixedly connected to one side of the support base 3, a pressure column 81 is slidably connected inside the oil reservoir 8, the top end of the pressure column 81 is connected to the lower surface of the stop 43, a piston plate is fixedly connected to the bottom of the pressure column 81 inside the oil reservoir 8, and an oil outlet pipe 82 is fixedly connected to the lower surface of the oil reservoir 8; during operation, when the stop 43 on the surface of the support base 3 rotates, the stop 43 will simultaneously drive the pressure column 81 on its surface to move, and then the pressure column 81 moves inside the oil reservoir 8, and applies pressure to the lubricating oil inside the oil reservoir 8, so that the lubricating oil inside the oil reservoir 8 flows through the oil outlet pipe 82 to one side of the threaded column 4 and the drill rod, lubricating the threaded column 4 and the drill rod, reducing the problem of excessive dust entering the threaded column 4 and the drill rod, which leads to greater friction when they rotate.

[0049] like Figure 7 As shown, an oil outlet film 83 is installed on the outer surface of the oil outlet pipe 82. The length of the oil outlet film 83 is greater than the length of the oil outlet pipe 82, and an oil outlet hole is opened on the surface of the oil outlet film 83. When the lubricating oil inside the oil storage tank 8 is squeezed, the lubricating oil will simultaneously squeeze the oil outlet film 83 at one end of the oil outlet pipe 82, making the diameter of the oil outlet hole on the surface of the oil outlet film 83 larger, thereby controlling the oil output to a certain extent and making it more convenient to use.

[0050] During operation, when the three-arm rock drill is drilling into the geology using the drill rod, the external drive simultaneously rotates the threaded column 4. The threaded column 4 then moves the threaded sleeve 41, which in turn moves the rotating rods 42 on both sides upwards. These rotating rods, in turn, rotate the stop seats 43 at the other end. The stop seats 43 then open and are positioned in a 'V' shape on both sides of the drill rod, effectively shielding the drill rod from flying debris during drilling and preventing it from affecting the workers. This design also allows for efficient use of space and enhances safety. Since this three-arm rock drill has three arms 2 that drill into different areas of surrounding rock, the stop seats 43 improve the safety of the drill rod during drilling. When debris is ejected during drilling, some of it impacts the pressure plate 5 on the surface of the stop seat 43. When the impact force is greater than the elastic force of the compression spring 52, and because the surface of the pressure plate 5 is rotatably connected to the surface of the stop 43, the impact force of the crushed stone will cause the pressure plate 5 to drive the anti-pressure inclined rod 51 and the compression spring 52 to rotate, thereby buffering the impact force of the crushed stone and reducing the possibility of some crushed stone entering the connection between the drill arm support and the frame; when the pressure plate 5 presses down on the anti-pressure inclined rod 51 to rotate, the pressure plate 5 will simultaneously pull the top rod 62 on its surface, causing the top rod 62 to pull the deflection rod 61 at its upper end, causing the deflection rod 61 to rotate at a certain angle inside the turntable 6, and then the deflection rod 61 will press against the piston rod 63 on one side, causing the piston rod 63 to squeeze the slurry inside the slurry storage tank 64 and spray it from the slurry outlet pipe 65 to one side of the drill rod, so that the slurry can not only play the role of slag removal, but also play the role of cleaning the borehole and reducing the wear rate of the drill rod.

[0051] Because the elastic potential energy of the compression spring 631 is less than that of the compression spring 52, the deflection rod 61 pulls the piston rod 63 and the compression spring 631 into a stretched state when it resets. Afterwards, when the compression spring 631 returns to its initial state, it again drives the piston rod 63 to push the slurry inside the slurry tank 64, further spraying the slurry onto the drill pipe surface. When the impact force of the crushed stone on the pressure plate 5 is large, the rotation angle of the pressure plate 5, the pressure rod 51, and the compression spring 52 will increase, causing the pressure plate 5 to move the push rod 62 a greater distance, thus increasing the rotation angle of the deflection rod 61. As the deflection angle increases, the first contact point 611 on the surface of the deflection rod 61 will contact the second contact point 612 inside the turntable 6. At this time, the external circuit is connected, causing the controller to record the surrounding rock at this location. Since this three-arm rock drill has three arms 2, and the three arms 2 drill different parts of the surrounding rock, the impact force generated by the broken rocks during the drilling process at different locations will affect whether the first contact point 611 and the second contact point 612 of different arms 2 are in contact. This allows for timely judgment of different levels of surrounding rock quality, and the controller determines the level of the surrounding rock, bringing convenience to geological exploration.

[0052] When the pressure plate 5 rotates, it simultaneously presses down on the pressure rod 71, causing the pressure rod 71 to rotate and thus causing some of the gravel falling onto the side surface of the pressure rod 71 to fall off, preventing excessive gravel accumulation from affecting the use of the drill rod itself. When the stop 43 on the surface of the support base 3 rotates, the stop 43 simultaneously moves the pressure column 81 on its surface. The pressure column 81 then moves inside the oil reservoir 8, providing pressure to the lubricating oil inside the oil reservoir 8. This causes the lubricating oil inside the oil reservoir 8 to flow through the oil outlet pipe 82 to one side of the threaded column 4 and the drill rod, lubricating the threaded column 4 and the drill rod and reducing the problem of excessive dust entering the threaded column 4 and the drill rod, which leads to high friction during rotation. The lubricating oil also squeezes the oil film 83 at one end of the oil outlet pipe 82, increasing the diameter of the oil outlet hole on the surface of the oil film 83, thereby controlling the oil output to a certain extent and making it more convenient to use.
