Description

Technical Field

[0001] This utility model relates to the field of mining technology. More specifically, this utility model relates to a drilling direction guiding device for drilling rigs used in mining. Background Technology

[0002] In some mining operations, drilling is required. Traditional drilling rigs can only drill downwards in one direction, making it difficult to adjust the drilling direction according to the ore body structure or terrain requirements. This results in a limitation on the drilling direction. For example, a drilling rig drilling direction guiding device for mining, patent application number "202321684128.5", uses a hydraulic cylinder to drive a guide plate and support frame to move vertically downwards. The downward movement of the support frame drives the drive motor to move vertically downwards, and at the same time, the drive motor drives the drill rod to drill. Its drilling direction can only be downwards, and the direction of the drill rod cannot be adjusted, which cannot meet the multi-angle drilling requirements under complex geological conditions. Summary of the Invention

[0003] Another objective of this invention is to provide a drilling direction guiding device for mining rigs that allows for adjustment of the drilling direction of the drill rod to meet the needs of multi-angle drilling under complex geological conditions.

[0004] To achieve these objectives and other advantages according to the present invention, a drilling direction guiding device for a drilling rig in mining is provided, comprising:

[0005] A frame, on one side of its top, has a turntable mounted on it, and a drive assembly is also mounted on the frame, the turntable being rotatably mounted on the frame via the drive assembly;

[0006] A limiting plate is horizontally fixedly disposed in the middle of the side of the turntable away from the frame. A guide plate is fixedly connected to the bottom of the limiting plate, and a slide rail is provided along the length of the side of the guide plate away from the turntable.

[0007] The hydraulic cylinder has its fixed end fixedly mounted on the top of the limiting plate, and its free end passing through the bottom of the limiting plate and connected to the drilling rig. The guide plate is located between the hydraulic cylinder and the turntable. The drilling rig is equipped with a slider, which is slidably mounted on the slide rail.

[0008] Preferably, the drive assembly includes a mounting plate, which is horizontally fixed on the outer side wall of the frame away from the turntable. A drive motor is mounted on the mounting plate. One end of the drive shaft of the drive motor is coaxially connected to a pin. The other end of the pin passes horizontally through the frame and is fixedly connected to the middle of the turntable side wall. The pin is rotatably connected to the frame.

[0009] Preferably, an arc-shaped guide rail is installed on the lower part of the frame near the turntable, and a sliding column is provided at the bottom of the guide plate near the turntable, the sliding column being slidably mounted on the arc-shaped guide rail.

[0010] Preferably, a mounting block is provided at the bottom of the outer wall of the slide rail, and two arc-shaped clamps are symmetrically arranged on the side of the mounting block away from the slide rail. The drill rod of the drilling rig is located between the two arc-shaped clamps and contacts the inner wall of the arc-shaped clamps.

[0011] Preferably, the frame includes a vertically arranged support plate, the turntable and the drive assembly are mounted on the support plate, a bottom plate is horizontally welded to the bottom of the support plate, and diagonal braces are welded between the bottom plate and the support plate.

[0012] Preferably, the base plate has multiple grooves for placing counterweights; the base plate also has multiple bolt holes, and an anchor bolt is installed in any one of the bolt holes.

[0013] This utility model has at least the following beneficial effects: By setting a rotating turntable on the frame, the drilling rig is connected to the turntable through a limiting plate. Driving the turntable to rotate drives the drilling rig to rotate, thereby adjusting the drilling angle of the drilling rig, making mining more flexible. The drilling rig is slidably connected to the slide rail through a slider, and the drilling rig is driven to move by a hydraulic cylinder. After the drilling angle is adjusted, the drilling rig is driven to slide on the slide rail by the hydraulic cylinder, thereby achieving the purpose of drilling holes in the mine.

[0022] like Figure 1-3 As shown, this utility model provides a drilling direction guiding device for drilling rigs used in mining, comprising:

[0023] A frame 1 has a turntable 2 mounted on one side of its top. A drive assembly 3 is also mounted on the frame 1. The turntable 2 is rotatably mounted on the frame 1 via the drive assembly 3.

[0024] A limiting plate 4 is horizontally fixedly disposed in the middle of the side of the turntable 2 away from the frame 1. A guide plate 5 is fixedly connected to the bottom of the limiting plate 4. A slide rail 501 is provided along the length of the side of the guide plate 5 away from the turntable 2.

[0025] The hydraulic cylinder 6 has its fixed end fixedly mounted on the top of the limiting plate 4, and its free end passing through the bottom of the limiting plate 4 and connected to the drilling rig 7. The guide plate 5 is located between the hydraulic cylinder 6 and the turntable 2. The drilling rig 7 is equipped with a slider 702, which is slidably mounted on the slide rail 501.

[0026] In the above technical solutions, such as Figure 1As shown, the frame 1 is installed on the ground, serving as the skeleton of the drilling direction guide device for the drill rig 7, and is used to install other components. The turntable 2 is installed on the frame 1, and a limit plate 4 is fixedly connected to the turntable 2. A guide plate 5 and a hydraulic cylinder 6 are fixedly connected to the limit plate 4. The guide plate 5 is used to install the slide rail 501. The drill rig 7 is connected to the free end of the hydraulic cylinder 6, and the drill rig 7 is also slidably connected to the slide rail 501 via a slider 702. The hydraulic cylinder 6 is used to drive the drill rig 7 to slide on the slide rail 501, thereby achieving the purpose of drilling holes in the mine using the drill rig 7. The drill rig 7 consists of a motor and a drill rod 701, driven by the motor... The moving drill rod 701 rotates to drill holes. A support can be installed on the free end of the hydraulic cylinder 6, and the support is fixed to the motor housing. The slider 702 is installed on the motor housing. The turntable 2 is driven to rotate by the drive assembly 3. The drive assembly 3 drives the turntable 2 to rotate, which can drive the drill 7 connected to the turntable 2 through the limit plate 4 to rotate. This allows the drilling angle of the drill 7 to be adjusted, making mining more flexible. The limit plate 4 can be fixed on the turntable 2 by welding or bolting. The hydraulic cylinder 6, guide plate 5, and slider 702 can all be fixed to the corresponding components by welding or bolting.

[0027] In another technical solution, the drive assembly 3 includes a mounting plate 301, which is horizontally fixed on the outer side wall of the frame 1 away from the turntable 2. A drive motor 302 is mounted on the mounting plate 301. The drive shaft of the drive motor 302 is coaxially connected to one end of a pin 303. The other end of the pin 303 passes horizontally through the frame 1 and is fixedly connected to the middle of the side wall of the turntable 2. The pin 303 is rotatably connected to the frame 1.

[0028] In this technical solution, a pin hole can be opened on the frame 1. The pin 303 is rotatably installed in the pin hole and its two ends protrude from the pin hole. One end of the pin 303 can be coaxially connected to the drive shaft of the drive motor 302 through a coupling, and the other end is welded to the middle of the turntable 2. The drive motor 302 drives the pin 303 to rotate, thereby driving the turntable 2 connected to the pin 303 to rotate. The drive motor 302 is installed on the frame 1 through the mounting plate 301.

[0029] In another technical solution, an arc-shaped guide rail 8 is installed on the lower part of the frame 1 near the turntable 2, and a sliding column 502 is provided on the bottom of the guide plate 5 near the turntable 2. The sliding column 502 is slidably mounted on the arc-shaped guide rail 8.

[0030] In this technical solution, such as Figure 2As shown, to improve the stability of the guide plate 5 and the drilling rig 7 during rotation, an arc-shaped guide rail 8 is installed on the frame 1, and a sliding column 502 is installed on the guide plate 5. During the process of driving the turntable 2 to rotate and causing the guide plate 5 and the drilling rig 7 to rotate, the bottom of the guide plate 5 follows the rotation on the arc-shaped guide rail 8 through the sliding column 502, thereby limiting the lower part of the guide plate 5 and improving the stability of the device during the adjustment of the drilling angle of the drilling rig 7. Limiting grooves can be opened on both outer sides of the arc-shaped guide rail 8. After the drilling angle of the drilling rig 7 is adjusted, the lower position of the guide plate 5 is fixed by U-shaped limiting blocks being locked in the limiting grooves to ensure the stability of the position of the drilling rig 7 after the drilling angle is adjusted.

[0031] In another technical solution, a mounting block 503 is provided at the bottom of the outer wall of the slide rail 501. Two arc-shaped clamping plates 504 are symmetrically arranged on the side of the mounting block 503 away from the slide rail 501. The drill rod 701 of the drilling rig 7 is located between the two arc-shaped clamping plates 504 and contacts the inner wall of the arc-shaped clamping plates 504.

[0032] In this technical solution, during the drilling process, due to geological conditions or mechanical vibration, the drill rod 701 is prone to deviation, affecting drilling accuracy. Therefore, if Figure 3 As shown, a mounting block 503 is provided at the bottom of the slide rail 501. Two arc-shaped clamping plates 504 are provided on the mounting block 503. The arc-shaped clamping plates 504 contact the outer wall of the drill rod 701 to limit the drill rod 701, prevent the drill rod 701 from deviating during drilling, and ensure drilling accuracy. The drill rod 701 only contacts the inner wall of the arc-shaped clamping plate 504, and the inner wall of the arc-shaped clamping plate 504 is a smooth arc surface, which will not affect the rotation of the drill rod 701. The mounting block 503 is located at the bottom of the slide rail 501 and can be used to prevent the drill rig 7 from sliding to the bottom of the slide rail 501 and derailing when the hydraulic cylinder 6 fails, thus ensuring the safety of the device.

[0033] In another technical solution, the frame 1 includes a vertically arranged support plate 101, the turntable 2 and the drive assembly 3 are mounted on the support plate 101, a bottom plate 102 is horizontally welded to the bottom of the support plate 101, and a diagonal brace 103 is welded between the bottom plate 102 and the support plate 101.

[0034] In this technical solution, the frame 1 is composed of a support plate 101, a base plate 102 and diagonal braces 103. The support plate 101, the base plate 102 and the diagonal braces 103 form a triangular cross-section structure, which has good support stability. Two sets of diagonal braces 103 are provided, which are spaced apart along the width direction of the base plate 102.

[0035] In another technical solution, the base plate 102 is provided with a plurality of grooves 104 for placing counterweights; the base plate 102 is also provided with a plurality of bolt holes 105, and an anchor bolt is installed in any bolt hole 105.

[0036] In this technical solution, the frame 1 is installed on the ground. If the ground to be installed is relatively flat, the counterweight can be placed in the groove 104 to ensure the stability of the frame 1 installation. If the ground to be installed has a slope, the frame 1 can be installed and fixed by inserting anchor bolts into the ground.

[0037] Working principle: When in use, the frame 1 is installed and fixed. According to the angle of the hole to be drilled, the drive motor 302 is started. The drive motor 302 drives the turntable 2 to rotate. The rotation of the turntable 2 drives the guide plate 5 and the drill 7 connected to it to rotate. At the same time, the bottom of the guide plate 5 slides on the arc-shaped guide rail 8 through the sliding column 502. When the drill 7 rotates to the angle of the hole to be drilled, the drive motor 302 is turned off. The hydraulic cylinder 6 is started at the same time to start the drill 7. The drill rod 701 is driven by the hydraulic cylinder 6 to move on the slide rail 501 toward the position of the hole to be drilled.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
