Description

Technical Field

[0001] This application relates to the field of geotechnical drilling equipment, and in particular to a geotechnical engineering exploration drilling device. Background Technology

[0002] In the field of geotechnical engineering construction, geotechnical engineering exploration drilling equipment can play a role in obtaining underground information, in-situ testing and monitoring, construction assistance and quality control, environmental assessment and remediation, etc., which has led to the widespread application of geotechnical engineering exploration drilling equipment in the work process of geotechnical engineering.

[0003] A related geotechnical engineering drilling device includes a frame, a cylinder fixedly mounted at the bottom of the frame, a lifting plate fixedly mounted at the lower end of the cylinder, the lifting plate being slidably connected to the frame, a motor fixedly mounted at the bottom of the lifting plate, the output end of the motor being fixedly connected to the drill rod, and multiple support legs spaced apart at the bottom of the frame. In use, the support legs are placed on the ground, the motor is started, causing the motor's output shaft to drive the drill rod to rotate, and then the cylinder is activated, causing the cylinder to push the lifting plate down, thereby allowing the drill rod to complete the drilling operation.

[0004] However, in actual construction, most frames cannot firmly stabilize the geotechnical engineering exploration drilling device on the ground. That is, when the drill rod is working, it will cause the exploration drilling device to rotate relative to the ground, which will cause the drilling work of the drill rod to deviate. Utility Model Content

[0005] To reduce the deviation of the drill rod during the exploration process, this application provides a drilling device for geotechnical engineering exploration.

[0006] This application provides a drilling device for geotechnical engineering exploration, which adopts the following technical solution:

[0007] A drilling device for geotechnical engineering exploration, comprising:

[0008] Mounting block, the mounting block is set on the ground, and the mounting block has a vertically arranged mounting cavity;

[0009] Mounting plate, which is horizontally fixed at the top of the mounting block;

[0010] Support columns, wherein multiple support columns are spaced apart along the axis of the mounting plate, and the support columns are fixedly installed at the bottom end of the mounting plate;

[0011] A support plate is provided, and each support plate is horizontally fixedly disposed at the lower end of the support column;

[0012] A lifting component is disposed on the mounting plate and slides within the mounting cavity;

[0013] A driving component, which is fixedly connected to the lifting component, is used to complete ground drilling;

[0014] The fastener is fixedly disposed within the support plate;

[0015] An anti-deviation component is disposed within the fixing component to reduce the deviation of the support column caused by drilling.

[0016] By adopting the above technical solution, the mounting block and mounting cavity are used to install the lifting component and the driving component. The mounting plate is used to install the support column and mounting block. The support column and support plate are used to increase the contact area between the exploration drilling device and the ground, thereby improving the stability of the exploration drilling device. The lifting component is used to drive the driving component to move up and down within the mounting cavity, thereby pushing the driving component to drill into the ground. The fixing component is used to install the anti-deviation component. Activating the lifting component allows it to slide within the mounting cavity. Since the driving component is fixedly connected to the lifting component, the lifting component drives the driving component to move vertically within the mounting cavity. Activating the driving component allows the ground drilling requirement to be met through its rotation.

[0017] Optionally, a sliding groove is vertically provided within the mounting cavity, and the lifting component includes:

[0018] A cylinder, the fixed end of which is vertically fixed to the mounting plate;

[0019] A sliding plate, the upper end of which is fixedly disposed at the telescopic end of the cylinder, and the sliding plate is slidably disposed within the sliding groove.

[0020] By adopting the above technical solution, the cylinder and sliding groove are used to control the sliding plate to slide within the mounting cavity. The sliding plate is used to install the driving component. When the cylinder is activated, as its extension end extends, the cylinder pushes the sliding plate to slide closer to the ground within the sliding groove. This causes the sliding plate to move the driving component closer to the ground, thereby enabling the driving component to complete the drilling operation. When the cylinder's extension end retracts, the cylinder pushes the sliding plate to slide further away from the ground within the sliding groove, causing the sliding plate to move the driving component further away from the ground.

[0021] Optionally, the driving element includes:

[0022] The motor is fixedly mounted on the bottom end of the sliding plate;

[0023] The drill rod is fixedly connected to the output shaft of the motor.

[0024] By employing the above technical solution, the motor is used to control the rotation of the drill rod, thereby achieving the drilling requirement on the ground. Since the motor is fixedly mounted at the bottom of the sliding plate, when the sliding plate slides towards the ground, it drives the motor to move towards the ground, which in turn pushes the drill rod towards the ground. Starting the motor causes its output shaft to rotate. Because the drill rod is fixedly connected to the motor's output shaft, the output shaft drives the drill rod to rotate, which in turn causes the sliding plate to push the motor and drill rod to complete the drilling operation on the ground.

[0025] Optionally, the fastener includes:

[0026] A fixing block, which is inserted into the support plate, and a fixing cavity is vertically provided inside the fixing block;

[0027] A fixing plate is fixedly disposed at the bottom end of the fixing cavity.

[0028] By adopting the above technical solution, the fixing block, fixing cavity and fixing plate are set up to realize the installation of the fixing plate and the anti-deviation component.

[0029] Optionally, the anti-deviation component includes:

[0030] The mating plates are arranged at intervals along the axis of the fixed plate. One end of each mating plate is fixedly connected to the upper end of the fixed plate, and the other end of each mating plate is provided with a first guide slope.

[0031] An adjusting block is threadedly connected to the fixed cavity, and a second guide slope is provided at the bottom end of the adjusting block;

[0032] A steel nail is inserted into the adjusting block and slidably connected to the adjusting block. The periphery of the steel nail abuts against the mating plate.

[0033] By adopting the above technical solution, the mating plate and the first guide slope are used to clamp the steel nail, thereby achieving a stable connection between the support plate and the ground, and further achieving a stable connection between the exploration drilling device and the ground. The adjusting block and the second guide slope are used to control the movement of the first guide slope, thereby controlling the mating plate to contact the steel nail. The steel nail, which passes through the adjusting block, is driven into the ground. Then, the adjusting block is rotated, causing the adjusting block to drive the first guide slope to rotate towards the ground, thereby causing the first guide slope to push the second guide slope towards the steel nail. This causes the second guide slope to drive the upper end of the mating plate to contact the steel nail, thereby achieving the purpose of fixing the support plate to the ground and reducing the deviation of the drill rod during the exploration process.

[0034] Optionally, multiple fasteners are provided, and each fastener corresponds to one of the support plates. The anti-deviation component corresponds to one of the fasteners.

[0035] By adopting the above technical solution, multiple fixing components and multiple anti-deviation components are set to improve the stability of the connection between the support plate and the ground, thereby improving the stability of the mounting block and reducing the deviation of the drill rod during the exploration process.

[0036] Optionally, each of the support plates is provided with a rotating opening, and a movable component is rotatably disposed within each rotating opening, the movable component comprising:

[0037] A rotating plate, which is rotatably disposed within the rotating opening;

[0038] The casters are fixedly mounted on one side of the rotating plate.

[0039] By adopting the above technical solution, the rotating plate is used to install the casters, and the rotating port is designed to allow the rotating plate and casters to rotate. Moving the rotating plate brings the casters closer to the ground, and then pushing the exploration drilling device allows it to move to the target position via the casters.

[0040] Optionally, each of the support plates is rotatably provided with buckles on both sides, with one side of each buckle abutting against the upper and lower ends of the rotating plate, respectively.

[0041] By adopting the above technical solution, the two latches are designed to reduce the rotation amplitude of the rotating plate, thereby reducing the swaying of the rotating plate during movement. Moving the rotating plate brings the caster close to the ground, and rotating the latches causes one end of the latch to contact both the rotating plate and the support plate.

[0042] Optionally, an anti-slip pad is fixedly provided on the inner side of the mating plate.

[0043] By adopting the above technical solution, the anti-slip pad is used to increase the friction between the mating plate and the steel nail, thereby improving the clamping effect of the mating plate on the steel nail.

[0044] In summary, the present invention provides a drilling device for geotechnical engineering exploration, which has at least one of the following beneficial technical effects:

[0045] 1. The mounting block and mounting cavity are designed to accommodate the lifting and driving components. The mounting plate is used to mount the support column and mounting block. The support column and support plate increase the contact area between the exploration drilling device and the ground, thereby improving the stability of the exploration drilling device. The lifting component drives the driving component to move up and down within the mounting cavity, thus propelling the driving component to drill into the ground. The fixing component is used to install the anti-deviation component. Activating the lifting component allows it to slide within the mounting cavity. Because the driving component is fixedly connected to the lifting component, the lifting component drives the driving component to move vertically within the mounting cavity. Activating the driving component allows the ground drilling to be completed through its rotation.

[0046] 2. The mating plate and the first guide ramp are used to clamp the steel nail, thereby achieving a stable connection between the support plate and the ground, and further achieving a stable connection between the exploration drilling device and the ground. The adjusting block and the second guide ramp are used to control the movement of the first guide ramp, thereby controlling the mating plate to contact the steel nail. The steel nail, which passes through the adjusting block, is driven into the ground. Then, the adjusting block is rotated, causing the adjusting block to drive the first guide ramp to rotate towards the ground, thereby causing the first guide ramp to push the second guide ramp towards the steel nail. This causes the second guide ramp to drive the upper end of the mating plate to contact the steel nail, thus achieving the purpose of fixing the support plate to the ground, thereby reducing the deviation of the drill rod during the exploration process.

[0053] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0054] Combination Figure 1 and Figure 2 This application discloses a drilling device for geotechnical engineering exploration, including a mounting block 1, a mounting plate 2, support columns 3, support plates 4, a lifting component 5, a driving component 6, a fixing component 7, and an anti-deviation component 8. The mounting block 1 is set on the ground, and a mounting cavity 11 is vertically arranged inside the mounting block 1. The mounting plate 2 is horizontally fixedly set at the top of the mounting block 1. Multiple support columns 3 are arranged at intervals along the axis of the mounting plate 2 and are fixedly set at the bottom of the mounting plate 2. Multiple support plates 4 are arranged, and each support plate 4 is horizontally fixedly set at the lower end of the support column 3. The lifting component 5 is set on the mounting plate 2 and slides in the mounting cavity 11. The driving component 6 is fixedly connected to the lifting component 5 and is used to complete ground drilling. The fixing component 7 is fixedly set inside the support plate 4, and the anti-deviation component 8 is set inside the fixing component 7 to reduce the deviation of the support column 3 caused by drilling.

[0055] In this embodiment, the mounting block 1 is cylindrical, and the mounting cavity 11 is cylindrical. The mounting cavity 11 is configured to meet the installation requirements of the drive component 6 and the lifting component 5. This embodiment does not impose specific limitations. The mounting plate 2 and the support column 3 are rectangular, and the support plate 4 is convex. The length and width of the mounting plate 2 shall not be less than the diameter of the mounting block 1, and the height of the support column 3 shall not be less than the length of the axis of the mounting block 1. The support column 3 is configured to meet the support requirements of the mounting block 1 and the mounting plate 2. The support column 3 and the support plate 4 are configured in a one-to-one correspondence, that is, the number of support columns 3 corresponds to the number of support plates 4, and the position of the support column 3 corresponds to the position of the support plate 4. The size of the support plate 4 is configured to meet the installation requirements of the fixing component 7 and the anti-deviation component 8. This embodiment does not impose specific limitations. Start the lifting component 5, which slides within the mounting cavity 11. Since the driving component 6 is fixedly connected to the lifting component 5, the lifting component 5 drives the driving component 6 to move vertically within the mounting cavity 11. Start the driving component 6, and the rotation of the driving component 6 will fulfill the ground drilling requirements.

[0056] In practical use, the exploration drilling device is placed on the target ground, so that the lower end of the support plate 4 is in contact with the ground. The anti-deviation component 8 is adjusted to fix it to the ground. Since the anti-deviation component 8 is set inside the fixing component 7, and the fixing component 7 is fixed inside the support plate 4, a stable connection between the support plate 4 and the ground is achieved, thereby reducing the deviation of the drill rod 62 during the exploration process. Then, the lifting component 5 is activated, causing it to slide closer to the ground within the mounting cavity 11. Since the driving component 6 is fixedly connected to the lifting component 5, the lifting component 5 drives the driving component 6 to move vertically downward within the mounting cavity 11. After the driving component 6 moves to contact the ground, the driving component 6 is activated, and the rotation of the driving component 6 achieves the drilling requirement.

[0057] Combination Figure 2 Specifically, a sliding groove 53 is vertically arranged inside the mounting cavity 11. The lifting component 5 includes a cylinder 51 and a sliding plate 52. The fixed end of the cylinder 51 is vertically fixed to the mounting plate 2, and the upper end of the sliding plate 52 is fixed to the telescopic end of the cylinder 51. The sliding plate 52 is slidably disposed within the sliding groove 53. The driving component 6 includes a motor 61 and a drill rod 62. The motor 61 is fixedly disposed at the bottom end of the sliding plate 52, and the drill rod 62 is fixedly connected to the output shaft of the motor 61.

[0058] In this embodiment, the sliding groove 53 is cylindrical, the sliding plate 52 is cylindrical, and the drill rod 62 includes a rod body and a drill bit. The rod body is cylindrical, and the drill bit is conical. One end of the rod body is fixedly connected to the bottom surface of the drill bit. The rod body and the drill bit can be integrally formed or fixed by welding or bolting, as long as the requirement of fixing one end of the rod body to the bottom surface of the drill bit is met. This embodiment does not impose specific limitations. When the cylinder 51 is activated, when the telescopic end of the cylinder 51 extends, the cylinder 51 pushes the sliding plate 52 to slide closer to the ground within the sliding groove 53. Since the motor 61 is fixedly installed at the bottom end of the sliding plate 52, the sliding plate 52 drives the motor 61 to move closer to the ground, thereby causing the motor 61 to push the drill rod 62 to move closer to the ground. Start the motor 61, causing the output shaft of the motor 61 to rotate. Since the drill rod 62 is fixedly connected to the output shaft of the motor 61, the output shaft of the motor 61 drives the drill rod 62 to rotate, which in turn causes the sliding plate 52 to push the motor 61 and the drill rod 62 to complete the drilling requirements on the ground.

[0059] In practical use, after the fixing part 7 and the anti-deviation part 8 are adjusted, that is, after the exploration drilling device is fixed on the ground, the cylinder 51 is started, and the extension end of the cylinder 51 is controlled to extend. The cylinder 51 will push the sliding plate 52 to slide in the sliding groove 53 towards the ground. Since the motor 61 is fixedly set at the bottom of the sliding plate 52, the sliding plate 52 drives the motor 61 to move towards the ground, thereby causing the motor 61 to push the drill rod 62 towards the ground. The motor 61 is started, causing the output shaft of the motor 61 to rotate. Since the drill rod 62 is fixedly connected to the output shaft of the motor 61, the output shaft of the motor 61 drives the drill rod 62 to rotate, thereby causing the sliding plate 52 to drive the motor 61 and the drill rod 62 to complete the drilling requirements of the ground. After drilling is completed, the motor 61 is turned off, and the telescopic end of the control cylinder 51 is shortened, so that the cylinder 51 pulls the sliding plate 52 to slide away from the ground in the sliding groove 53. Since the motor 61 is fixedly set at the bottom of the sliding plate 52, the sliding plate 52 drives the motor 61 to move away from the ground, thereby causing the motor 61 to pull the drill rod 62 to move away from the ground.

[0060] Combination Figure 2 , Figure 3 and Figure 4 Specifically, the fixing component 7 includes a fixing block 71 and a fixing plate 72. The fixing block 71 passes through the support plate 4, and a fixing cavity 711 is vertically arranged inside the fixing block 71. The fixing plate 72 is fixedly arranged at the bottom end of the fixing cavity 711. The anti-deviation component 8 includes a mating plate 81, an adjusting block 82, and a steel nail 83. Multiple mating plates 81 are arranged at intervals along the axis of the fixing plate 72. One end of each mating plate 81 is fixedly connected to the upper end of the fixing plate 72, and the other end of each mating plate 81 is provided with a first guide slope 811. The adjusting block 82 is threadedly connected to the fixing cavity 711, and a second guide slope 821 is provided at the bottom end of the adjusting block 82. The steel nail 83 passes through the adjusting block 82 and is slidably connected to the adjusting block 82. The periphery of the steel nail 83 abuts against the mating plate 81. Multiple fixing components 7 are provided, and each fixing component 7 corresponds to one of the support plates 4. The anti-deviation component 8 is also provided in a corresponding manner to each fixing component 7. An anti-slip pad is fixedly installed on the inner side of the mating plate 81.

[0061] Combination Figure 3 and Figure 4 More specifically, each support plate 4 is provided with a rotating opening 93, and a movable component 9 is rotatably disposed within each rotating opening 93. The movable component 9 includes a rotating plate 91 and a universal wheel 92. The rotating plate 91 is rotatably disposed within the rotating opening 93, and the universal wheel 92 is fixedly disposed on one side of the rotating plate 91. Each support plate 4 is rotatably disposed on both sides with a latch 94, one side of each latch 94 abutting against the upper and lower ends of the rotating plate 91, respectively.

[0062] In this embodiment, the fixing block 71 is cylindrical, the fixing plate 72 is annular, and the fixing cavity 711 is cylindrical. The fixing cavity 711 is designed to meet the installation requirements of the fixing plate 72. The mating plate 81 is rectangular and made of an elastic material. The material of the mating plate 81 is designed to meet the clamping requirements of the steel. The mating plate 81 and the fixing plate 72 can be integrally formed or fixed by welding or bolting, as long as one end of the mating plate 81 is fixedly connected to the upper end of the fixing plate 72. The adjusting block 82 is cylindrical, with external threads on its outer periphery and internal threads on its inner periphery. The external and internal threads enable a threaded connection between the adjusting block 82 and the fixing block 71. The first guide slope 811 and the second guide slope 821 are arranged in a one-to-one correspondence, that is, the number of the first guide slope 811 and the number of the second guide slope 821 are arranged in a one-to-one correspondence, and the position of the first guide slope 811 and the position of the second guide slope 821 are arranged in a one-to-one correspondence. The arrangement of the first guide slope 811 and the second guide slope 821 is sufficient to meet the requirement of the adjusting block 82 pushing the mating plate 81. The steel nail 83 is arranged in a cylindrical shape, and one end of the steel nail 83 is provided with a conical protrusion. The arrangement of the steel nail 83 is sufficient to meet the fixed connection between the anti-deviation component 8 and the fixing component 7 and the ground. This application embodiment does not make specific limitations. The fixing component 7 and the support plate 4 are arranged in a one-to-one correspondence, that is, the number of fixing components 7 and the number of the support plates 4 are arranged in a one-to-one correspondence, and the position of the fixing component 7 and the position of the fixing component 8 are arranged in a one-to-one correspondence. A steel nail 83, which is inserted into the adjusting block 82, is driven into the ground. Then, the adjusting block 82 is rotated, causing the second guide inclined surface 821 to rotate towards the ground. This causes the second guide inclined surface 821 to push the first guide inclined surface 811 towards the steel nail 83, thereby causing the upper end of the mating plate 81 to come into contact with the steel nail 83. This achieves the purpose of fixing the support plate 4 to the ground, thereby reducing the deviation of the drill rod 62 during the exploration process.

[0063] The rotating opening 93 is rectangular, and the rotating plate 91 is also rectangular. The rotating plate 91 is designed to accommodate the installation of the caster wheel 92, and the rotating opening 93 is designed to accommodate the rotation of both the rotating plate 91 and the caster wheel 92. This embodiment does not impose specific limitations on these aspects. The latch 94 is also rectangular, and its design is sufficient to restrict the rotation of the rotating plate 91. By moving the rotating plate 91, the caster wheel 92 is brought closer to the ground. Then, the latch 94 is rotated so that one end of the latch 94 contacts both the rotating plate 91 and the support plate 4, thereby reducing the rotation amplitude of the rotating plate 91.

[0064] In practical use, when it is necessary to move the exploration drilling device to the target position, the rotating plate 91 is turned so that the caster 92 is close to the ground. The buckle 94 is rotated so that one end of the buckle 94 is in contact with both the rotating plate 91 and the support plate 4, thereby reducing the rotation range of the rotating plate 91. The mounting plate 2 is pushed so that the exploration drilling device is moved to the target position via the caster 92. Then the buckle 94 is rotated so that one end of the buckle 94 is in contact with only the support plate 4. The rotating plate 91 is turned so that the caster 92 is away from the ground, thereby making the support plate 4 in contact with the ground. After the support plate 4 is in contact with the ground, the steel nail 83 inserted in the adjusting block 82 is driven into the ground. Then, the adjusting block 82 is rotated, causing the adjusting block 82 to drive the second guide inclined surface 821 to rotate closer to the ground. This causes the second guide inclined surface 821 to push the first guide inclined surface 811 to move closer to the steel nail 83. Consequently, the first guide inclined surface 811 causes the upper end of the mating plate 81 to contact the steel nail 83, thereby fixing the support plate 4 to the ground and reducing the deviation of the drill rod 62 during the exploration process.

[0065] After drilling is completed, rotate the adjusting block 82, causing it to rotate the second guide ramp 821 away from the ground. This moves the second guide ramp 821 away from the first guide ramp 811. Due to the restorative property of the mating plate 81, the upper end of the mating plate 81 moves away from the steel nail 83, thus pulling the steel nail 83 out of the ground. After all the steel nails 83 are pulled out of the ground, move the rotating plate 91 so that the caster wheel 92 is close to the ground. Rotate the latch 94 so that one end of the latch 94 abuts against both the rotating plate 91 and the support plate 4. Then push the mounting plate 2 so that the exploration drilling device moves to the storage position via the caster wheel 92.

[0066] The implementation principle of this application embodiment is as follows: the rotating plate 91 is moved so that the caster wheel 92 is close to the ground, the buckle 94 is rotated so that one end of the buckle 94 abuts against both the rotating plate 91 and the support plate 4, thereby reducing the rotation amplitude of the rotating plate 91, pushing the mounting plate 2, so that the exploration drilling device moves to the target position through the caster wheel 92, and then the buckle 94 is rotated so that one end of the buckle 94 abuts only against the support plate 4, the rotating plate 91 is moved so that the caster wheel 92 is away from the ground, thereby making the support plate 4 abut against the ground. After the support plate 4 is in contact with the ground, the steel nail 83 inserted in the adjusting block 82 is driven into the ground. Then, the adjusting block 82 is rotated, causing the adjusting block 82 to drive the second guide inclined surface 821 to rotate closer to the ground. This causes the second guide inclined surface 821 to push the first guide inclined surface 811 to move closer to the steel nail 83. Consequently, the first guide inclined surface 811 causes the upper end of the mating plate 81 to contact the steel nail 83, thereby fixing the support plate 4 to the ground and reducing the deviation of the drill rod 62 during the exploration process. The cylinder 51 is activated, and its extension end is extended. The cylinder 51 pushes the sliding plate 52 to slide closer to the ground within the sliding groove 53. Since the motor 61 is fixedly mounted at the bottom of the sliding plate 52, the sliding plate 52 drives the motor 61 to move closer to the ground, thereby causing the motor 61 to push the drill rod 62 to move closer to the ground. The motor 61 is activated, causing its output shaft to rotate. Since the drill rod 62 is fixedly connected to the output shaft of the motor 61, the output shaft of the motor 61 drives the drill rod 62 to rotate, thereby causing the sliding plate 52 to drive the motor 61 and the drill rod 62 to complete the drilling requirements on the ground.

[0067] After drilling is completed, motor 61 is turned off, and the telescopic end of cylinder 51 is shortened, causing cylinder 51 to pull sliding plate 52 to slide away from the ground within sliding groove 53. Since motor 61 is fixedly mounted at the bottom of sliding plate 52, sliding plate 52 drives motor 61 to move away from the ground, thereby causing motor 61 to pull drill rod 62 away from the ground. Then, adjusting block 82 is rotated, causing second guide inclined surface 821 to rotate away from the ground, thus moving second guide inclined surface 821 away from first guide inclined surface 811. Due to the restorative property of mating plate 81, the upper end of mating plate 81 moves away from steel nail 83, thereby pulling steel nail 83 out of the ground. After all the steel nails 83 have been pulled out of the ground, move the rotating plate 91 so that the caster wheel 92 is close to the ground, rotate the buckle 94 so that one end of the buckle 94 is in contact with both the rotating plate 91 and the support plate 4, and then push the mounting plate 2 so that the exploration drilling device can be moved to the storage position via the caster wheel 92.

[0068] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
