[0001] The invention belongs to the technical field of engineering construction, and in particular, relates to a civil engineering intelligent exploration and sampling device for roads. Background Art

[0002] In the field of civil engineering, especially in road exploration and sampling, traditional sampling devices often face multiple challenges. First, in hard geological conditions, traditional devices are often difficult to sample effectively, usually relying on a single rotation or impact force, which not only leads to low sampling efficiency, but also easily causes wear or damage to the drill bit.

[0003] Secondly, the existing equipment lacks an effective cooling and dust removal mechanism during the sampling process, which makes the drill bit prone to overheating when working in a high temperature and dusty environment, increases the complexity of equipment maintenance, and may affect the quality of sampling. The traditional method is to water the outside, with poor water penetration and general protection effect.

[0004] In addition, due to insufficient consideration of the center of gravity and vibration control of the device in the design, the device has poor stability during the sampling process and is prone to tilting or shaking, resulting in reduced sampling accuracy and even affecting subsequent sample analysis. In short, the existing sampling device cannot provide sufficient flexibility and stability when facing complex geological conditions and is easily damaged.

[0005] Therefore, an improved solution is needed that can provide higher sampling efficiency, better protect the drill bit and improve equipment stability under different geological conditions.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0042] like Figures 1 to 7 As shown, a civil engineering intelligent exploration and sampling device for roads includes a vehicle body 1;

[0043] Two vertical frames 2 are symmetrically fixedly connected to the upper surface of the vehicle body 1, and the opposite surfaces of the two vertical frames 2 are slidably provided with a support frame 3;

[0044] The protective shell 4 is fixedly connected to the bottom of the support frame 3, and a main shaft 8 is slidably penetrated through the inner wall of the protective shell 4, and a sampling drill bit 9 is fixedly connected to the bottom end of the main shaft 8;

[0045] The top end of the main shaft 8 is fixedly connected with a bearing seat 10, and the upper surface of the bearing seat 10 is provided with a spring 12 supported by a top pressure frame 13;

[0046] Impact assembly 6 The impact assembly 6 is fixedly connected to the inner wall of the protective shell 4 and the surface of the main shaft 8, and is used to form an impact force on the sampling drill bit 9 through the main shaft 8;

[0047] Driver 5 Driver 5 is fixedly connected to one side of the protective shell 4, and a part of the driver 5 penetrates and rotates on the inner wall of the shell, and is used to drive the impact assembly 6 and the main shaft 8 to rotate;

[0048] Two electric telescopic rods 19 are symmetrically fixed on the outside of the two support frames 3, and the top of the electric telescopic rod 19 is movably connected with a support pin 7, and the support pin 7 is fixed on one side of the support frame 3;

[0049] A water supply tank 17 is fixedly connected to the upper surface of the vehicle body 1 , and the water supply tank 17 supplies water to the sampling drill bit 9 through a hose 16 .

[0050] This solution achieves precise adjustment of sampling pressure and impact force through the intelligently controlled electric telescopic rod 19, so that the device has excellent sampling capabilities under hard geological conditions. The coordinated design of rotational force and impact force ensures that the sampling drill bit 9 generates a strong impact force when rotating, thereby improving the sampling efficiency and reducing the wear of the drill bit. The cooling and dust exhaust system effectively reduces the workload of the drill bit in high temperature and dusty environments through the design of the water supply tank 17 and the rotary joint, thereby extending the service life of the equipment. The elastic downforce design provides effective protection when encountering hard objects, prevents equipment damage, and improves the operational safety and reliability of the device. In addition, the reasonable counterweight design ensures the stability of the equipment during the sampling process, thereby ensuring high-precision sample collection and improving overall work efficiency.

[0051] Specifically, Figure 1 As shown: a handle 15 is fixedly connected to the upper surface of the stand 2, and a sliding hole 18 for sliding with a fixing pin is opened on the surface of the stand 2.

[0052] By providing the handle 15, the handle 15 can be conveniently held and can be deflected as a whole. By applying a force in the F direction through the handle 15, the sampling drill bit 9 can be tilted with less force, so as to facilitate taking out samples.

[0053] By providing the sliding hole 18, the sliding hole 18 can maintain the vertical movement trajectory of the fixing pin, and at the same time can maintain the horizontal limit when the fixing pin rotates.

[0054] Specifically, Figure 3As shown: the driver 5 includes a motor 51 fixedly connected to one side of the protective shell 4, the output shaft of the motor 51 is fixedly connected to a driving wheel 52, the surface of the driving wheel 52 is connected to a driven wheel 53 through a belt drive, a spline sleeve 54 is axially penetrated and fixed on the driven wheel 53, the spline sleeve 54 is rotated at the bottom of the protective shell 4 through a bearing, and the spline sleeve 54 is spline-fitted on the surface of the main shaft 8.

[0055] By providing the spline sleeve 54, the spline sleeve 54 can rotate with the main shaft 8, and when moving in the vertical direction, the spline sleeve 54 and the main shaft 8 do not interfere with each other. The spline sleeve 54 is driven by the driven wheel 53, and rotates with the rotating seat 61 and the main shaft 8 at the same time. The spline sleeve 54 rotates on the inner wall of the protective shell 4 to maintain stability.

[0056] Specifically, Figure 4 As shown: the top of the spring 12 is fixedly connected with a top pressure frame 13, the top pressure frame 13 is fixedly connected to the inner wall of the support frame 3, and two guide rods 14 slide through the surface of the top pressure frame 13, and the guide rods 14 are fixedly connected to the upper surface of the spring 12 seat 11.

[0057] By setting a top pressure frame 13, the top pressure frame 13 serves as the top support of the spring 12, moves with the movement of the support frame 3, and applies force to the spring 12 seat 11 through the spring 12. The lower surface of the spring 12 seat 11 is rotatably fixed to the top of the main shaft 8 through the bearing seat 10, and can provide a vertical force when the main shaft 8 rotates.

[0058] Specifically, Figure 5 As shown: the impact assembly 6 includes a rotating seat 61 fixedly connected to the top of the spline sleeve 54, the inner wall of the rotating seat 61 is meshed with a plurality of gears 62, the top of the gear 62 is fixed with a plurality of elastic rods 63, one end of the elastic rod 63 is provided with a ball head 64, the gear 62 is penetrated by a fixed ear 65 for rotation, and the fixed ear 65 is fixedly connected to the inner wall of the protective shell 4;

[0059] The impact assembly 6 further includes a rotary disk 66 fixedly connected to the surface of the main shaft 8 , and a plurality of buffer wheels 67 are rotatably mounted on the upper surface of the rotary disk 66 .

[0060] By setting a rotating seat 61, the rotating seat 61 rotates coaxially with the main shaft 8, so that the meshing gear 62 rotates, forming a reverse rotation mechanism, thereby achieving the mutual collision of the ball head 64 and the buffer wheel 67 during relative movement, wherein the horizontal friction force of the collision is largely unloaded by the rotation of the buffer wheel 67, and the vertical force is transmitted to the main shaft 8 through the turntable 66.

[0061] Specifically, Figure 1 As shown: a sampling port 22 for the sampling drill 9 to pass through is opened on the surface of the vehicle body 1, and universal wheels 21 are arranged at the four corners of the vehicle body 1.

[0062] The sampling port 22 can facilitate the downward movement of the sampling drill bit 9 for sampling drilling, and protect the area around the sampling drill bit 9 to prevent people from approaching, thereby improving the safety of use.

[0063] The universal wheel 21 can be easily pushed to move to the designated sampling position.

[0064] Specifically, Figure 2 As shown: a baffle 20 is fixedly connected to one side of the top of the stand 2, and the baffle 20 overlaps one side of the support frame 3.

[0065] The baffle 20 is fixed on one side of the stand 2 and can limit the top of the support frame 3 so that the support frame 3 cannot deflect and move in the direction of the baffle 20 .

[0066] Specifically, Figure 4 As shown, the main shaft 8 is hollow, and the bottom end of the main shaft 8 is connected to the top of the sampling drill bit 9, and the top end of the main shaft 8 is connected to one end of the hose 16 through a rotary joint.

[0067] The main shaft 8 is hollow so that it can maintain water flow transmission while rotating. When water flow is transmitted inside the main shaft 8, the temperature on the surface of the main shaft 8 can be dissipated.

[0068] Specifically, Figure 5 As shown, the fixed ear 65 supports the gear 62 in an inclined state, and the gear 62 and the elastic rod 63 are rotatably arranged in an inclined state, and the inner wall of the rotating seat 61 is meshed with the gear 62 in an inclined state.

[0069] The tilted elastic rod 63 can maintain a certain degree of bending after being hit hard, and then reset.

[0070] When the present solution is in use, a suitable downward force is provided by the intelligently controlled electric telescopic rod 19, so that the sampling drill bit 9 is lowered and fitted to the road surface, and then the driver 5 is started. The driver 5 starts to rotate with the spline sleeve 54 under the transmission action of the belt through the driving wheel 52 and the driven wheel 53. The spline sleeve 54 rotates with the main shaft 8 at high speed under the action of the spline cooperation. When the main shaft 8 rotates, it rotates with the sampling drill bit 9 and the rotating disk 66 on the surface. At the same time, the spline sleeve 54 rotates with the rotating seat 61, and the rotating seat 61 starts to rotate with the gear 62 on the inner wall. The rotation direction of the rotating seat 61 is consistent with that of the main shaft 8, and the rotation direction of the gear 62 meshing with the inner wall is opposite to that of the main shaft 8. When the gear 62 rotates with the elastic rod 63 and the ball head 64 of the top, the main shaft 8 rotates with the rotating disk 66 and the buffer wheel 67 in the opposite direction.

[0071] When the fixing pin is subjected to a downward pressure from the electric telescopic rod 19 on the support frame 3, the support frame 3 provides a downward pressure on the spline sleeve 54 through the protective shell 4, so that the spline sleeve 54 slides downward slightly on the surface of the main shaft 8, and the spring 12 is compressed synchronously (the main shaft 8 and the sampling drill bit 9 are subjected to the reverse support force of the ground). At this time, the applied pressure is converted into an elastic downward pressure from the spring 12, so that the sampling drill bit 9 always has an elastic downward pressure, and at the same time, the spline sleeve 54 moves downward to a certain extent on the surface of the spline shaft. At this time, the protective shell 4 moves downward synchronously, so that the fixing ear 65 moves downward slightly with the gear 62, the elastic rod 63 and the ball head 64 as the protective shell 4 moves downward. The main shaft 8 and the rotating disk 66 on the surface remain unchanged, so that the high-speed rotating ball head 64 contacts the reverse rotating rotating disk 66, and the buffer wheel 67 on the surface of the rotating disk 66 collides with the ball head 64, so that the horizontal friction force is greatly reduced by the rotation of the buffer wheel 67, and the vertical impact force is transmitted to the main shaft 8 and the sampling drill bit 9 through the rotating disk 66. The buffer wheel 67 maintains a high-speed rotation state during the continuous collision, and its own rotation and the collision between multiple ball heads 64 make the main shaft 8 transmit a relatively dense impact force to the sampling drill bit 9. The vertical impact force of the sampling drill bit 9 is transmitted to the ground, and the rest is affected by the spring 12, which will not cause excessive shaking to the vehicle body 1.

[0072] The drill bit is subjected to a dense downward impact force and continuously drills and taps while rotating to complete the sampling. When this solution is used normally, combined with Figure 7 As shown, the motor 51 is subjected to gravity G, so that it rotates in the direction R with the fixed pin as the rotation center, and the rotation directions of the two ends are L1 and L2 respectively, wherein the L1 force at the top is blocked by the baffle 20, so that the baffle 20 provides a Z-direction support force, at this time, the whole is supported and the sampling drill 9 is in a vertical downward state, and when the sampling is completed, the handle 15 is held and pulled to form an F-direction force, so that the force offsets the gravity G of the motor 51 (the whole only has the motor 51 on one side as a counterweight), so that L1 and L2 start to move in the opposite direction, and at this time the sampling drill 9 is in a tilted state, and the motor 51 is started, and the soil sample inside can be taken out under the action of the impact force;

[0073] In summary, this solution can change the downward distance of the ball head 64 and the distance of the rotary disk 66 according to the change of the downward pressure, so that the sampling drill bit 9 can form a downward pressure sampling, and the change of the downward pressure and the impact force will change in direct proportion at the same time. The greater the pressure, the greater the impact force, and the smaller the pressure, the lower the impact force. The electric telescopic rod 19 can realize intelligent control of the drilling pressure and impact force changes of the sampling.

[0074] At the same time, the present invention converts the downward pressure on the main shaft 8 and the sampling drill bit 9 into elastic downward pressure through the spring 12, so that the drill bit can rebound when encountering metal objects to avoid overall damage caused by rigid downward pressure. The overall counterweight design adopts a high-power motor 51, supported by the vehicle body 1 and the universal wheel 21, has higher sampling efficiency, and combines the weight of the high-power motor 51 to form an overall balancing mechanism, which can facilitate the maintenance of vertical stability and the quick operation of removing samples.

[0075] In the above scheme, further, during use, the rotary joint at the top of the main shaft 8 can maintain communication with one end of the hose 16 in a rotating state, so that the water pump built into the water supply tank 17 pumps out the water, and transmits it to the main shaft 8 through the hose 16, and transmits it to the inner wall of the sampling drill bit 9 through the main shaft 8. At this time, the inner wall of the sampling drill bit 9 is gradually filled with water, and the water can be discharged along the gap of the drill bit, which can meet the sampling needs of asphalt, cement and other roads, and can flush out the drilled powder in time, while reducing the temperature of the end friction, protecting the sampling drill bit 9 to reduce dust, and ensuring that the sampling surface is more beautiful.

[0076] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
