Description

Technical Field

[0001] The utility model relates to the technical field of roadbed detection tools, in particular to a drilling device for detecting the compactness of a roadbed. Background Art

[0002] The roadbed is the foundation of the pavement structure, and its compaction directly affects the stability, durability and service life of the road surface. Good roadbed compaction can effectively reduce road settlement, cracks and deformation, and improve the bearing capacity and service life of the road surface. Therefore, after the shoulder is compacted, it is necessary to drill holes to take samples and then test them. When sampling, the sampling depth and location are usually determined according to engineering requirements and design specifications. For example, if the density of the entire roadbed needs to be evaluated, sampling may be carried out at different depths (such as 0-30 cm, 30-60 cm, 60-90 cm, etc.), and the samples at each depth may be subjected to laboratory analysis.

[0003] The current drilling sampling equipment is relatively simple, using a drilling machine to drill holes to extract the soil. However, when drilling holes for sampling, the depth cannot be controlled, and the sampled soil depth may be too deep or too shallow, resulting in errors in the analysis and detection data. In order to solve this problem, we proposed a drilling device for roadbed compaction detection. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figures 1 to 6, which is the first embodiment of the utility model, and provides a drilling device for detecting the compaction degree of roadbed, which can achieve the effect of limiting the drilling depth of the drill bit, and includes a frame main body mechanism 100, which includes a footrest base plate 101, and also includes a support frame 102 arranged on the footrest base plate 101, and a drilling assembly 103 slidably mounted on the support frame 102, the support frame 102 includes a limit slide bar 102a arranged at the top of the footrest base plate 101 near the center position, and also includes a tooth groove opened on the limit slide bar 102a 102a-1, and a scale mark 102a-2 arranged on one side of the limiting slide bar 102a, a positioning mechanism 200, which includes a positioning sleeve 201 slidably installed on the limiting slide bar 102a, and also includes a first accommodating cavity 201a opened on one side of the inner cavity of the positioning sleeve 201, and a first clamping member 202 arranged in the first accommodating cavity 201a, the positioning sleeve 201 slides on the limiting slide bar 102a to adjust the blocking position of the drilling depth, and the positioning sleeve 201 blocks the drilling assembly 103 from moving down to drill.

[0029] The drilling assembly 103 includes a limiting sleeve 103a slidably mounted on the limiting slide bar 102a, and a second accommodating cavity 103a-1 is opened on the limiting sleeve 103a, and a second clamping member 103b is movably installed in the second accommodating cavity 103a-1, and the second clamping member 103b matches the second accommodating cavity 103a-1. After the second clamping member 103b is retracted into the second accommodating cavity 103a-1, the limiting sleeve 103a and the limiting slide bar 102a can slide unimpeded.

[0030] The drilling assembly 103 further includes a driving motor 103f disposed on one side of the limiting sleeve 103a, and a drill bit 103g disposed on one end of the output shaft of the driving motor 103f. A handheld handle 103h is fixedly mounted on one side of the driving motor 103f via a bracket.

[0031] In this embodiment, after selecting the drilling location, the equipment is moved to the drilling location, and the drilling component 103 is slidably installed on the limiting slide bar 102a. Under the action of gravity, the drilling component 103 slides along the limiting slide bar 102a and is located on the ground to be drilled. At this time, the bottom end of the limiting sleeve block 103a slidably installed on the limiting slide bar 102a in the drilling component 103 is flush with the zero point position of the scale mark 102a-2. Then, according to the drilling depth required by the project, the positioning sleeve block 201 is moved up and down to align the top of the positioning sleeve block 201 with the scale mark 102a-2 on the project. The required drilling depth is the same as the required drilling depth, and then the first clamping piece 202 is clamped with the tooth groove 102a-1 on the limiting slide bar 102a to fix the positioning sleeve 201, and the driving motor 103f is started to drive the drill bit 103g to rotate. The staff holds the handheld handle 103h tightly and presses down. The downward pressure makes the drilling assembly 103 press down to drill a hole. When the bottom end of the limiting sleeve 103a contacts the positioning sleeve 201, the drill bit 103g can no longer move downward to drill a hole, which means that the drilling is completed, so that the size and depth of the hole drilled are more standard.

[0032] Example 2, reference Figures 1 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, a first oil chamber 201b is connected to and opened on one side of the inner wall of the first accommodating chamber 201a on the positioning sleeve 201, and an oil hole 201c is provided on the top of the first oil chamber 201b. A first piston 203 is arranged in the first oil chamber 201b, and a first push rod 204 and a pull rod 205 are respectively welded at both ends of the first piston 203. One end of the first push rod 204 passes through one side of the first oil chamber 201b and extends to the first accommodating chamber 201a and is fixedly connected with the first clamping member 202. One end of the pull rod 205 passes through the other side of the first oil chamber 201b and extends to the outside of the positioning sleeve 201. A stopper 206 is welded on one end of the pull rod 205 that passes through the other side of the first oil chamber 201b and extends to the outside of the positioning sleeve 201.

[0033] A first extrusion spring 207 is disposed in the first oil chamber 201b and is sleeved on the outside of the circumferential side wall of the pull rod 205. Two ends of the first extrusion spring 207 respectively contact one side of the first piston 203 and the inner wall of the first oil chamber 201b.

[0034] A driving rod 300 is rotatably installed on the lower end of one side of the positioning sleeve 201, and a U-shaped clamp 301 is arranged on the driving rod 300. The groove of the U-shaped clamp 301 and the pull rod 205 are movably matched, and the side wall of the U-shaped clamp 301 and the stop block 206 are in contact and matched. An auxiliary grip rod 302 is obliquely arranged on one side of the bottom end of the positioning sleeve 201, and the auxiliary grip rod 302 and the driving rod 300 are matched correspondingly. The auxiliary grip rod 302 is inclined to stay away from the limiting slide rod 102a, so that the auxiliary grip rod 302 and the driving rod 300 are easy to operate when they are held and driven.

[0035] The first piston 203 is pushed out of the first accommodating cavity 201a by the elastic force of the first extrusion spring 207 to move in the direction of the tooth groove 102a-1. The first piston 203 pushes the first clamping piece 202 out of the first accommodating cavity 201a through the first push rod 204 and matches and clamps the tooth groove 102a-1 on the limiting slide bar 102a, so that the positioning sleeve 201 is fixed on the limiting slide bar 102a without being affected by external forces. When the position of the positioning sleeve 201 needs to be adjusted, by holding the driving rod 300 and the auxiliary gripping rod 302 tightly, because the auxiliary gripping rod 302 is fixed, the driving rod 300 will rotate along the rotating shaft, thereby driving the U-shaped clip 301 to push the stopper 206, so that it drives the first clamping piece 202 to retract into the first accommodating cavity 201a through the pull rod 205, so that the positioning sleeve 201 can slide on the limiting slide bar 102a without obstacles, thereby realizing the unlocking of the positioning sleeve 201 on the limiting slide bar 102a.

[0036] A second oil chamber 103a-2 is connected to the limiting sleeve 103a on one side of the inner wall of the second accommodating chamber 103a-1, and the second oil chamber 103a-2 is U-shaped. Second pistons 103c are provided at both ends of the U-shape of the second oil chamber 103a-2, and a second push rod 103d is welded to one end of the second piston 103c. The second push rod 103d penetrates the second oil chamber 103a-2 and extends into the second accommodating chamber 103a-1 and is fixedly connected with the second clamping member 103b. A second extrusion spring 103e is sleeved on the second push rod 103d, and the two ends of the second extrusion spring 103e respectively conflict with one side of the second piston 103c and the inner wall of the second oil chamber 103a-2.

[0037] In this embodiment, the second oil chamber 103a-2 is designed in a U-shape so that there are two second push rods 103d on one side of the second clamping piece 103b, so that after the second clamping piece 103b is clamped with the tooth groove 102a-1, the limiting sleeve 103a is more stable and reliable. In the initial state, the second clamping piece 103b is pushed by the second extrusion spring 103e to shrink into the second accommodating chamber 103a-1, so that the limiting sleeve 103a and the limiting slide rod 102a are slidably installed.

[0038] The oil hole 201c on the positioning sleeve 201 is connected to an oil delivery conduit 400, and the other end of the oil delivery conduit 400 is in communication with the second oil chamber 103a-2.

[0039] In this embodiment, the auxiliary gripping rod 302 and the driving rod 300 are gripped, and the pull rod 205 is driven to move in a direction away from the limiting sliding rod 102a through the U-shaped clamp 301, so that the first clamping member 202 connected by the first push rod 204 is disengaged from the tooth groove 102a-1 to complete unlocking, so that the positioning sleeve 201 can slide up and down without obstacles. When the first clamping member 202 is unlocked, the first piston 203 moves along with the pull rod 205, squeezing the oil in the first oil chamber 201b, so that the squeezed oil enters the oil delivery conduit 400 through the oil hole 201c, and then enters the second oil chamber 103a-2. The squeezing force of the oil pushes the second piston 103c, and the second clamping member 103b is pushed out of the second accommodating chamber 103a-2 through the second push rod 103d. 3a-1 and matches and snaps with the tooth groove 102a-1 on the limiting slide bar 102a, so that the limiting sleeve 103a is fixed on the limiting slide bar 102a. When the positioning sleeve 201 is adjusted to a specific position, the auxiliary grip 302 and the driving rod 300 are released, and the elastic force of the first extrusion spring 207 pushes the first piston 203 to move in the direction of the first clamping piece 202, thereby pushing the first clamping piece 202 and the tooth groove 102a-1 to match and snap, so that the positioning sleeve 201 is fixed on the limiting slide bar 102a to limit the drilling depth. The second extrusion spring 103e pushes the second piston 103c to move in the direction away from the tooth groove 102a-1, so that the second clamping piece 103b is separated from the tooth groove 102a-1, so that the drilling assembly 103 can be manually pressed down to drive drilling.

[0040] The rest of the structure is the same as that of Example 1.

[0041] Example 3, reference Figures 1 to 6 , which is the third embodiment of the utility model. Different from the previous embodiment, the support frame 102 also includes a support rod 102b symmetrically arranged on one side of the top of the footrest base 101, and a triangular connecting frame 102c arranged on the top of the support rod 102b, and the symmetrical support rod 102b and the limiting slide rod 102a are fixedly connected by the triangular connecting frame 102c.

[0042] A pulley 104 is disposed on one side of the bottom end of the footrest 101 , and the angle between the footrest 101 and the support frame 102 is greater than 90 degrees.

[0043] In this embodiment, the footrest 101 is arranged at an angle through the setting of the pulley 104 when drilling. In order to ensure that the drilling component 103 is perpendicular to the ground, the angle between the footrest 101 and the support frame 102 is greater than 90 degrees. At the same time, through the setting of the pulley 104, when transporting and walking, the triangular connecting frame 102c between the symmetrical support rods 102b is held by hand to make the pulley 104 roll on the ground, and the end of the footrest 101 away from the pulley 104 is tilted to realize the walking of the equipment. In order to ensure stability during drilling, during construction, the staff should stand on the footrest 101.

[0044] The rest of the structure is the same as that of Example 1.
