Description

Technical Field

[0001] The present application relates to the field of road detection technology, and in particular to an asphalt pavement sampler for ordinary road engineering. Background Art

[0002] Before sampling asphalt pavement, the sampling location and time must be determined. Typically, sampling should be done at the edge of the pavement or at locations with cracks, potholes, and other issues to ensure the sample is representative. Sampling should be done when the pavement temperature is stable, there is no rainfall, and there is no mechanical damage. When sampling asphalt pavement, a rotary sampler is typically used. The sampler is inserted into the pavement at the specified depth and angle, then rotated to remove the asphalt from the pavement and place it in a sample bag.

[0003] However, when the current sampler is rotating for sampling, it is easy to shake and centrifuge during the drilling process due to the influence of factors such as mechanical vibration, thereby affecting the sampling effect. Utility Model Content

[0034] The present application discloses an asphalt pavement sampler for common road engineering projects, comprising a support base, a first movable assembly, a drill barrel, a first motor, and a clamping assembly. Before sampling asphalt, the sampler is moved to a working position. The clamping assembly is controlled to move toward the drill barrel, clamping the drill barrel in place. Because the side of the clamping assembly facing the drill barrel rotates with the drill barrel, the drill barrel is not affected by its up and down movement or rotation. Specifically, during asphalt sampling, the drill barrel is driven vertically downward by the first movable assembly, while the first motor is activated, causing the first motor to rotate the drill barrel. When the drill barrel contacts the working pavement, sampling of the asphalt on the pavement begins. When the drill barrel is inserted into the pavement to a specified depth, the drill barrel is controlled to move downward away from the pavement, and the cut asphalt is removed. Therefore, during the drill barrel's rotational sampling process, the clamping and positioning function of the clamping assembly improves the stability of the drill barrel, making it less prone to shaking and centrifugal forces.

[0048] In order to improve the stability of the drill barrel during sampling, the embodiment of the present application proposes a new asphalt pavement sampler for ordinary road engineering.

[0049] Reference Figure 1 , an asphalt pavement sampler for general road engineering, comprising:

[0050] The support base 1 has an operation through hole 15 on its bottom surface;

[0051] A first moving assembly 5 is provided on the support base 1;

[0052] The drill barrel 3 is connected to the first movable assembly 5, and the first movable assembly 5 can drive the drill barrel 3 to move up and down in the vertical direction. The drill barrel 3 matches the operating through hole 15;

[0053] a first motor 4, the first motor 4 being connected to the first moving assembly 5, and the output shaft of the first motor 4 being connected to the drill pipe 3; and

[0054] The clamping assembly 2 includes at least two clamping assemblies 2 symmetrically arranged along the drill barrel 3. The clamping assembly 2 is slidably connected to the support seat 1, and the clamping assembly 2 can move toward and away from the drill barrel 3. The side of the clamping assembly 2 facing the drill barrel 3 rotates with the drill barrel 3.

[0055] In this embodiment, the operation through hole 15 is used for the drill barrel 3 to pass through the support seat 1; that is, the matching of the drill barrel 3 and the operation through hole 15 means that the positions of the drill barrel 3 and the operation through hole 15 correspond to each other.

[0056] Specifically, before asphalt sampling, the sampler is moved to the working position. The clamping assembly 2 is controlled to move toward the drill barrel 3, thereby clamping and positioning the drill barrel 3. Since the side of the clamping assembly 2 facing the drill barrel 3 rotates with the drill barrel 3, the drill barrel 3 is not affected by its up and down movement and rotation. That is, during asphalt sampling, the drill barrel 3 is driven downward in the vertical direction by the first moving assembly 5, while the first motor 4 is activated to rotate the drill barrel 3. When the drill barrel 3 contacts the working road surface, asphalt sampling begins. When the drill barrel 3 is inserted into the road surface to a specified depth, the drill barrel 3 is controlled to move downward away from the road surface, and the cut asphalt is then removed.

[0057] The common asphalt pavement sampler for road engineering of the above embodiment includes a support base 1, a first moving assembly 5, a drill barrel 3, a first motor 4, and a clamping assembly 2. During the rotational sampling process of the drill barrel 3, the clamping and positioning function of the clamping assembly 2 improves the stability of the drill barrel 3 and makes it less prone to shaking and centrifugal movement.

[0058] As an implementable approach, refer to Figures 1 to 4 , the clamping assembly 2 includes:

[0059] A second movable assembly 6, the second movable assembly 6 is connected to the bottom surface of the support base 1;

[0060] The clamping part includes a connecting part 7, a clamping part 14 and a ball 8. The connecting part 7 is connected to the second movable component 6, and the second movable component 6 can drive the connecting part 7 to move toward and away from the drill barrel 3; the clamping part 14 is connected to the connecting part 7, and the side of the clamping part 14 facing the drill barrel 3 matches the drill barrel 3; the ball 8 is embedded and rollingly arranged in the clamping part 14, and the ball 8 protrudes from the side of the clamping part 14 facing the drill barrel 3.

[0061] In this embodiment, when clamping the drill barrel 3, the second movable assembly 6 drives the connecting portion 7 toward the drill barrel 3, at which point the connecting portion 7 simultaneously drives the clamping portion 14 to move. When the balls 8 on each clamping portion 14 contact the drill barrel 3, the drill barrel 3 is positioned, ensuring that the drill barrel 3 does not wobble during rotation. When the drill barrel 3 needs to be released, the second movable assembly 6 drives the connecting portion 7 away from the drill barrel 3, at which point the connecting portion 7 simultaneously drives the clamping portion 14 until the clamping portion 14 is away from the drill barrel 3.

[0062] It should be noted that the balls 8 are embedded and rollably disposed within the clamping portion 14, protruding from the side of the clamping portion 14 facing the drill tube 3. Specifically, the clamping portion 14 defines a cavity 17 within which the balls 8 rotate, and the outer wall of the clamping portion 14 defines a retaining hole 18 for retaining the balls 8. The diameter of the retaining hole 18 is smaller than the maximum diameter of the balls 8. As the drill tube 3 rotates and moves up and down, the balls 8 rotate within their respective cavities 17 in coordination with the drill tube 3.

[0063] As an implementable approach, refer to Figure 2 and Figure 3 , the second moving component 6 includes:

[0064] The fixing seat 13 is connected to the bottom surface of the supporting seat 1 and has a movable groove 12;

[0065] The second threaded rod 11 is disposed in the movable groove 12 , and both ends of the second threaded rod 11 are rotatably connected to the fixed seat 13 ;

[0066] Turning the knob 9, the knob 9 is connected to the end of the fixing base 13 away from the drill tube 3, and the knob 9 is connected to one end of the second threaded rod 11; and,

[0067] The second moving block 16 is threadedly sleeved on the second threaded rod 11 . Both sides of the second moving block 16 are slidably connected to the fixing seat 13 , and the top surface of the second moving block 16 is connected to the connecting portion 7 .

[0068] In this embodiment, when the drill barrel 3 needs to be clamped, the rotating knob 9 is held and rotated. The rotating knob 9 drives the second threaded rod 11 to rotate. Since the two sides of the second movable block 16 are restricted by the fixed seat 13, when the second threaded rod 11 rotates, the second movable block 16 moves along the long axis direction of the second threaded rod 11, that is, the second movable block 16 moves toward the direction close to the drill barrel 3. When the second movable block 16 moves, it simultaneously drives the connecting part 7 to move, so that the clamping part 14 clamps and positions the drill barrel 3. The operation is simple, and the position of the clamping part 14 can be quickly adjusted.

[0069] As an implementable approach, refer to Figure 2 and Figure 3 , an anti-slip portion 10 is provided on the rotating knob 9.

[0070] In this embodiment, the anti-slip portion 10 can play an anti-slip role when the rotating knob 9 is rotated, making it easier to rotate the rotating knob 9.

[0071] In some embodiments, the anti-slip portion 10 can be formed by a protrusion arranged along the circumferential direction of the rotating knob 9, or by a groove opened on the rotating knob 9, or by an anti-slip sleeve mounted on the rotating knob 9.

[0072] As an implementable approach, refer to Figure 5 The number of balls 8 is several, and the balls 8 are evenly distributed on the clamping portion 14 in an array.

[0073] In this embodiment, a plurality of balls 8 evenly distributed in an array are provided, which can better cooperate with the rotation and up and down movement of the drill tube 3 when clamping the drill tube 3, thereby preventing the drill tube 3 from getting stuck during rotation and up and down movement.

[0074] As an implementable approach, refer to Figure 2 and Figure 3 The number of the clamping assemblies 2 is four, and the four clamping assemblies 2 are evenly distributed along the circumferential direction of the drill tube 3 .

[0075] In this embodiment, when there are only two clamping assemblies 2, to better clamp the drill barrel 3 and better match the outer contour of the drill barrel 3, the width of the two clamping assemblies 2 is relatively wide, and the contours of the clamping portions 14 of the two clamping assemblies 2 are similar to the outer contour of the drill barrel 3 of this specification. That is, when a larger asphalt sample is required, the larger drill barrel 3 is replaced. In this case, the contours of the two clamping assemblies 2 and the larger drill barrel 3 differ significantly. When clamping the drill barrel 3, the contact area between the clamping assemblies 2 and the drill barrel 3 is significantly reduced, which means that the stability of the drill barrel 3 during rotation is reduced. When there are four clamping assemblies 2, the four clamping assemblies 2 can clamp the drill barrel 3 from four angles. When the specifications of the drill barrel 3 change, whether it increases or decreases, the four clamping assemblies 2 can still clamp the drill barrel 3, effectively ensuring the stability of the drill barrel 3 during rotation.

[0076] As an implementable approach, refer to Figure 1 and Figure 6 , the first moving component 5 includes:

[0077] A first threaded rod 22, one end of the threaded rod being rotatably connected to the top surface of the support base 1, and the other end of the first threaded rod 22 being rotatably connected to the bottom surface of the support base 1;

[0078] A second motor, the second motor is connected to the top surface of the support base 1, and the output shaft of the second motor is connected to one end of the first threaded rod 22;

[0079] A first moving block, the first moving block is threadedly sleeved on the first threaded rod 22, and the first moving block is slidably connected to the support base 1;

[0080] The movable plate 23 has one side connected to the first movable block, a bottom surface of the movable plate 23 is connected to the drill pipe 3 , and the first motor 4 is connected to the movable plate 23 .

[0081] In this embodiment, when the height of the drill barrel 3 needs to be adjusted, that is, the drill barrel 3 needs to move up and down, the second motor is turned on, and the second motor drives the first threaded rod 22 to rotate. Since the first moving block is slidingly connected to the support seat 1, when the first threaded rod 22 rotates, the first moving block moves upward or downward along the long axis direction of the first threaded rod 22 (that is, the vertical direction). When the first moving block moves upward or downward, it will synchronously drive the moving plate 23 and the drill barrel 3 to move upward or downward.

[0082] As an implementable approach, refer to Figure 5 The first moving assembly 5 also includes a limit block, and the support seat 1 is provided with a slide groove along the vertical direction, and the limit block is slidably connected to the slide groove.

[0083] In this embodiment, the limit block is slidably connected to the slide groove, which can limit the first moving block and ensure that the first moving block does not rotate and always moves upward or downward along the first threaded rod 22.

[0084] As an implementable approach, refer to Figure 5 The sampler further includes a pushing assembly 26, which is connected to the support base 1 in a detachable manner.

[0085] In this embodiment, the push assembly 26 is used to move the entire sampler. When the sampler's position needs to be adjusted remotely, the push assembly 26 is connected to the support base 1 and then pushed, causing the entire sampler to move synchronously. During asphalt sampling, the push assembly 26 can be removed to prevent vibrations from the push assembly 26 during the sampling process, causing the entire sampler to move and affect the asphalt sampling process.

[0086] As an implementable approach, refer to Figure 5 , the pushing component 26 includes:

[0087] Connecting frame 25, connecting frame 25 is connected to support base 1;

[0088] Universal wheels 27, the number of which is four, and the four universal wheels 27 are evenly distributed on the bottom surface of the connecting frame 25; and,

[0089] The handle 24 is connected to the connecting frame 25 .

[0090] In this embodiment, when the entire sampler needs to be moved, the handle 24 is held and the connecting frame 25 is pushed under the action of the universal wheel 27, so that the entire sampler moves synchronously.

[0091] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
