Description
Technical Field
[0001] This utility model relates to the field of road surface detection technology, and in particular to a road surface detection sampling device for highway reconstruction and expansion. Background Technology
[0002] With the development of society and economy, the amount of new construction and renovation of existing municipal roads and highway asphalt pavements in my country has increased. Highway structures can be roughly divided into base course and surface course. After the construction of both base course and surface course is completed, sampling and testing are required to check whether they are qualified. However, the testing of highway pavement requires mechanical drilling and core sampling. However, existing core sampling machines have problems with operation, such as the difficulty in demolding the test sample inside the core sampler. Therefore, this solution provides a pavement testing and sampling device for highway reconstruction and expansion. Utility Model Content
[0003] The purpose of this invention is to provide a road surface testing and sampling device for highway reconstruction and expansion that is simple to operate and easy to demold.
[0004] This utility model is achieved through the following measures: A road surface testing and sampling device for highway reconstruction and expansion is characterized in that it includes a support frame, on which a drilling mechanism is provided; The drilling mechanism includes a core tube with several gear-shaped drill bits arranged circumferentially on the lower end face of the core tube. The core tube rotates, causing the drill bits to rotate, thereby drilling through the road surface to extract the core. An inverted U-shaped frame 1 is provided at the upper end of the core tube. An electric telescopic rod is provided on the upper side of the U-shaped frame 1. An inverted U-shaped frame 2 is provided at the upper end of the electric telescopic rod. A matching push plate is slidably arranged inside the core tube. The push plate is fixedly arranged on the U-shaped frame 2. Under the action of the electric telescopic rod, the test sample inside the core tube is pushed down and demolded by the push plate.
[0005] The specific features of this utility model also include: A cutting mechanism is provided on the lower end face of the core tube. The cutting mechanism includes a ring that cooperates with the core tube. Specifically, the ring can be fixed to the core tube by welding. A plurality of drill bits are provided on the lower end face of the ring. An annular groove is coaxially provided on the upper end face of the ring. A rotating shaft is provided on both sides of the annular groove. A cutter that can be housed in the annular groove is provided around the rotating shaft. The cutters on both sides are symmetrically arranged. When rotating, they can cut most of the test sample in the core tube, so that the test sample can be easily removed from the road surface. This prevents the test sample from prematurely demolding during the lifting of the core tube, which would cause the problem of not being able to collect the sample. Since the cutter is short, it can be housed in the annular groove during drilling. After drilling is completed, the rotating shaft is rotated again so that the cutter cuts most of the test sample.
[0006] The core tube is provided with a pair of through holes that cooperate with the rotating shaft. The through holes pass through the upper and lower end faces of the core tube. After the rotating shaft passes through the through holes, a gear 1 is provided on its outer periphery. A motor 1 is provided on the inner side of the U-shaped frame 1. A gear 2 is provided on the output shaft of the motor 1, which meshes with both sides of the gear 1. The gear 2 is provided with a pair of through holes that cooperate with the U-shaped frame 2. The two sides of the U-shaped frame 2 pass through the through holes and are connected to the push plate. Since the angle of rotation of the cutter will not exceed a certain degree, there will be no interference between the gear 2 and the U-shaped frame 2. After drilling is completed, the motor drives the gear 2 to rotate, which in turn drives the gear 1 to rotate, which in turn drives the shaft to rotate, which in turn drives the cutter to rotate, thereby achieving the cutting of most of the bottom of the test sample.
[0007] The drilling mechanism also includes a driving mechanism, which includes a vertically arranged rectangular frame, a circular shaft rotatably arranged on the lower inner side of the rectangular frame, a gear three arranged around the circular shaft, a motor two arranged on the lower inner inner side of the rectangular frame, and a gear four meshing with the gear three arranged around the output shaft of the motor two. A pair of brackets are provided on the upper end face of the core tube, and an upper end plate is provided between the pair of brackets. The lower end of the round shaft passes through the rectangular frame and is placed on the upper end plate. The second motor drives the fourth gear to rotate, which in turn drives the third gear to rotate, which in turn drives the round shaft to rotate, which in turn drives the core tube to rotate, thereby realizing the drilling operation.
[0008] A handle is provided on the upper side of the rectangular frame.
[0009] The support frame includes a pair of parallel vertical plates. The two sides of the vertical plates near the lower end are connected into a whole by a connecting plate. The gap between the connecting plate and the vertical plates is sufficient to allow the core tube to pass through. The inner sides of the two vertical plates are provided with grooves. The sliding sliders are slidably arranged in the grooves. The rectangular frame is provided between the sliders.
[0010] Both sides of the vertical plates are equipped with handles at the top. The entire device can be moved to the sampling position by the handles. Then, the drilling mechanism can be lowered by the handles. It should also be noted that when not in use, the drilling mechanism can be temporarily fixed to the support frame with ropes.
[0011] During sampling, the entire device is first moved to the desired sampling position using the handle, so that the sampling point is located in the gap between the connecting plates on both sides and the vertical plates on both sides. Then, the drilling mechanism is lowered using the handle to perform sampling. At the same time, motor two is started, which drives gear four to rotate, thereby driving gear three to rotate, which in turn drives the circular shaft to rotate, and thus drives the core tube to rotate, realizing the drilling operation. After drilling is completed, motor one is started, which drives gear two to rotate, which in turn drives gear one to rotate, which in turn drives the rotating shaft to rotate, and thus drives the cutter to rotate, realizing the cutting of most of the bottom of the test sample, making it easier to extract the test sample in the core tube from the road surface. Then, a collection box is placed below the core tube, and then the electric telescopic rod is started. Under the action of the electric telescopic rod, the test sample in the core tube is pushed down and demolded by the push plate, finally completing the sampling.
[0012] The beneficial effects of this utility model are as follows: the device has a simple structure and is easy to operate. The push plate makes it easy for the sample to be demolded from the core extractor after sampling. In addition, the cutter also makes sampling easier, thus improving sampling efficiency and quality.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0021] See Figures 1-3 A road surface testing and sampling device for highway reconstruction and expansion includes a support frame and a drilling mechanism installed on the support frame. The drilling mechanism includes a core tube 3. Several gear-shaped drill bits 1 are arranged around the lower end of the core tube 3. When the core tube 3 rotates, it drives the drill bits 1 to rotate, thereby drilling through the road surface to extract the core. An inverted U-shaped frame 14 is arranged at the upper end of the core tube 3. An electric telescopic rod 16 is arranged on the upper side of the U-shaped frame 14. An inverted U-shaped frame 2 17 is arranged at the upper end of the electric telescopic rod 16. A matching push plate 18 is slidably arranged inside the core tube 3. The push plate 18 is fixedly arranged on the U-shaped frame 2 17. Under the action of the electric telescopic rod 16, the test sample inside the core tube 3 is pushed down and demolded by the push plate 18.
[0022] A cutting mechanism is provided on the lower end face of the core tube 3. The cutting mechanism includes a ring 2 that cooperates with the core tube 3. Specifically, the ring 2 can be fixed to the core tube 3 by welding. Several drill bits 1 are provided on the lower end face of the ring 2. An annular groove 23 is coaxially provided on the upper end face of the ring 2. A rotating shaft 21 is provided on both sides of the annular groove 23. A cutter 22 that can be stored in the annular groove 23 is provided around the rotating shaft 21. The cutters 22 on both sides are symmetrically arranged. When rotating, they can cut most of the test sample in the core tube 3, so that the test sample can be easily removed from the road surface. This prevents the test sample from being demolded prematurely during the lifting of the core tube 3, which would cause the problem of not being able to collect the sample. Since the cutter 22 is short, it can be stored in the annular groove 23 during the drilling process. After the drilling is completed, the rotating shaft 21 is rotated again so that the cutter 22 cuts most of the test sample.
[0023] The core tube 3 is provided with a pair of through holes that cooperate with the rotating shaft 21. The through holes pass through the upper and lower end faces of the core tube 3. After the rotating shaft 21 passes through the through holes, a gear 20 is provided on its outer periphery. A motor 15 is provided on the inner side of the U-shaped frame 14. A gear 19 is provided on the output shaft of the motor 15 that meshes with both gears 20. A pair of through holes are provided on the gear 19 that cooperate with the U-shaped frame 17. The two sides of the U-shaped frame 17 pass through the through holes and are connected to the push plate 18. Since the angle of rotation of the cutter 22 will not exceed 180 degrees, there will be no interference between the gear 19 and the U-shaped frame 17. After drilling is completed, motor 15 drives gear 29 to rotate, which in turn drives gear 20 to rotate, which in turn drives shaft 21 to rotate, which in turn drives cutter 22 to rotate, thus achieving the cutting of most of the bottom of the test sample.
[0024] The drilling mechanism also includes a drive mechanism, which includes a vertically arranged rectangular frame 8, a circular shaft 6 rotatably arranged on the lower inner side of the rectangular frame 8, a gear 9 arranged around the circular shaft 6, a motor 12 arranged on the lower inner side of the rectangular frame 8, and a gear 11 meshing with the gear 9 arranged around the output shaft of the motor 12. A pair of brackets are provided on the upper end face of the core tube 3, and an upper end plate 5 is provided between the pair of brackets. The lower end of the round shaft 6 passes through the rectangular frame 8 and is placed on the upper end plate 5. The motor 2 12 drives the gear 4 11 to rotate, which in turn drives the gear 3 9 to rotate, which in turn drives the round shaft 6 to rotate, which in turn drives the core tube 3 to rotate, thus realizing the drilling operation.
[0025] A handle 10 is provided on the upper side of the rectangular frame 8.
[0026] The support frame includes a pair of parallel vertical plates 4. The two sides of the vertical plates 4 near the lower end are connected into a whole by a connecting plate 13. The gap between the two connecting plates 13 and the two vertical plates 4 is sufficient to allow the core tube 3 to pass through. The inner sides of the two vertical plates 4 are provided with grooves, and the two grooves are provided with matching sliders. A rectangular frame 8 is provided between the two sliders.
[0027] Handles 7 are provided at the top of both vertical plates 4. The entire device can be moved to the sampling position by means of handles 7. Then, the drilling mechanism can be lowered by means of handle 10. It should also be noted that when not in use, the drilling mechanism can be temporarily fixed to the support frame with ropes.
[0028] During sampling, the entire device is first moved to the sampling position using handle 7, so that the sampling point is located in the gap between the two connecting plates 13 and the two vertical plates 4. Then, the drilling mechanism is lowered using handle 10 to perform sampling. At the same time, motor 2 12 is started, which drives gear 4 11 to rotate, which in turn drives gear 3 9 to rotate, which in turn drives the round shaft 6 to rotate, which in turn drives the core tube 3 to rotate, thus realizing the drilling operation. After drilling is completed, motor 1 15 is started, which drives gear 2 19 to rotate, which in turn drives gear 1 20 to rotate, which in turn drives the rotating shaft 21 to rotate, which in turn drives the cutter 22 to rotate, thus realizing the cutting of most of the bottom of the test sample, making it easier to extract the test sample in the core tube 3 from the road surface. Then, a collection box is placed below the core tube 3, and then the electric telescopic rod 16 is started. Under the action of the electric telescopic rod 16, the test sample in the core tube 3 is pushed down and demolded by the push plate 18, thus completing the sampling.
[0029] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
