Description

Technical Field

[0001] This utility model relates to the technical field of traffic engineering, and in particular to a traffic engineering quality testing device. Background Technology

[0002] With the rapid development of my country's road transportation industry and the significant improvement in the modernization level of highway transportation, the requirements for highway engineering quality have also increased, especially the increasingly stringent standards for the smoothness of roadbeds and pavements. In the current highway traffic environment, the quality of roadbeds and pavements directly affects many aspects such as driving safety, fuel consumption, driving speed, mechanical wear, and driving comfort. Therefore, sampling and testing of roadbeds and pavements has become a crucial link in ensuring pavement quality.

[0003] Some sampling and testing equipment uses a core drill to drill holes in the road for sampling. During the drilling and sampling process, the sampling depth is determined manually. However, the thickness of the road varies in different road environments. This can lead to situations where the sampling tube fails to completely separate the sampling part from the road, making it impossible to extract the sample. Alternatively, the sampling tube may continue to penetrate the soil in the roadbed layer after penetrating the road, resulting in invalid sampling at the bottom. Summary of the Invention

[0004] In view of the problems in the existing road sampling process, such as the bottom of the sample being difficult to separate from the road, making it inconvenient to remove the sample, and the sampling equipment being inconvenient to quickly replace the sampling tube, which reduces the efficiency of continuous road sampling, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a traffic engineering quality testing device, the purpose of which is to: quickly separate the sample from the road using road sampling equipment, and quickly separate and install the sampling tube from the sampling equipment.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a traffic engineering quality testing device, including a testing frame, a rotating mechanism fixedly installed on the top of the testing frame, a pressure sampling mechanism fixedly installed on the inner wall of the testing frame, and a sample removal mechanism provided on the top of the testing frame away from the rotating mechanism.

[0008] In a preferred embodiment of the traffic engineering quality testing device of this utility model, the rotating mechanism further includes a slot, which is formed on the outer surface of the connecting rod. A locking block is rotatably mounted on the outer surface of the connecting rod. The inner surface of the locking block is engaged with the connecting block through a locking rod. The opposite sides of the two connecting blocks are fixedly connected to the outer surface of the connecting rod.

[0009] In a preferred embodiment of the traffic engineering quality testing device of this utility model, the pressure sampling mechanism includes a limiting block, the top of which is fixedly connected to the inner wall of the testing frame, and a hydraulic cylinder is rotatably mounted on the inner surface of the limiting block via a movable block. A hydraulic rod is fixedly mounted on the piston of the hydraulic cylinder, and a clamp is fixedly mounted on the bottom end of the hydraulic rod.

[0010] In a preferred embodiment of the traffic engineering quality testing device of this utility model, the pressure sampling mechanism further includes a sampling drill barrel, the outer surface of which is engaged with the inner surface of the clamp, and the top end of which is threadedly connected to the inner surface of the connecting rod.

[0011] As a preferred embodiment of the traffic engineering quality testing device of this utility model, the pressure sampling mechanism further includes a vibration component, the vibration component includes a vibration box, the top of the vibration box is fixedly connected to the bottom of the card holder, a second motor is fixedly installed in the inner cavity of the vibration box through a connecting frame, a second rotating shaft is fixedly installed at the output end of the second motor through a reducer, and an eccentric block is fixedly installed on the outer surface of the second rotating shaft.

[0012] In a preferred embodiment of the traffic engineering quality testing device of this utility model, the sample removal mechanism includes an air pump, the bottom of which is fixedly connected to the top of the testing frame, and the top of which is connected to an air pipe.

The inner surface of the connecting air box is rotatably connected to the outer surface of the first rotating shaft. The outer surface of the connecting air box is connected to the right end of the air pipe. The communicating hole is formed through the outer surface of the first rotating shaft.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. By adding an automatic sample extraction design to the testing equipment, the present invention achieves rapid extraction of foundation samples and rapid separation of the sample in the sampling drill barrel from the foundation by using a No. 1 motor and a No. 1 rotating shaft in conjunction with a slide bar and a connecting rod, a connecting rod and a clamping block in conjunction with a sampling drill barrel and a clamping frame, a hydraulic cylinder and a hydraulic rod in conjunction with a clamping frame and a limiting block, an air pump and an air pipe in conjunction with a connecting air box and a connecting hole, a connecting hole in conjunction with a No. 1 rotating shaft, a clamping frame and a vibration box in conjunction with a No. 2 motor and a No. 2 rotating shaft, and a No. 2 rotating shaft in conjunction with an eccentric block.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0023] Reference Figures 1-5 The first embodiment of this utility model provides a traffic engineering quality testing device, which includes a testing frame 1, a rotating mechanism 2 fixedly installed on the top of the testing frame 1, a pressure sampling mechanism 3 fixedly installed on the inner wall of the testing frame 1, and a sample removal mechanism 4 provided on the top of the testing frame 1 away from the rotating mechanism 2.

[0024] The rotating mechanism 2 includes a fixed frame 21. The bottom of the fixed frame 21 is fixedly connected to the top of the detection frame 1. A motor 22 is movably mounted on the inner surface of the fixed frame 21 via a hinge. A rotating shaft 23 is fixedly mounted on the output end of the motor 22 via a reducer. A connecting rod 25 is slidably mounted on the outer surface of the rotating shaft 23 via a slide bar 24.

[0025] The pressure sampling mechanism 3 includes a limiting block 31. The top of the limiting block 31 is fixedly connected to the inner wall of the detection frame 1. A hydraulic cylinder 32 is rotatably mounted on the inner surface of the limiting block 31 through a movable block. A hydraulic rod 33 is fixedly mounted on the piston of the hydraulic cylinder 32. A clamp 34 is fixedly mounted on the bottom end of the hydraulic rod 33.

[0026] The pressure sampling mechanism 3 also includes a sampling drill barrel 35, the outer surface of which is engaged with the inner surface of the bracket 34, and the top of the sampling drill barrel 35 is threadedly connected to the inner surface of the connecting rod 25.

[0027] The pressure sampling mechanism 3 also includes a vibration assembly 36, which includes a vibration box 361. The top of the vibration box 361 is fixedly connected to the bottom of the card holder 34. A second motor 362 is fixedly installed in the inner cavity of the vibration box 361 through a connecting frame. A second rotating shaft 363 is fixedly installed at the output end of the second motor 362 through a reducer. An eccentric block 364 is fixedly installed on the outer surface of the second rotating shaft 363.

[0028] The sample removal mechanism 4 includes an air pump 41, the bottom of which is fixedly connected to the top of the detection frame 1, and the top of the air pump 41 is connected to an air pipe 42.

[0029] The sample removal mechanism 4 also includes a connecting air box 43 and a connecting hole 44. The inner surface of the connecting air box 43 is rotatably connected to the outer surface of the first rotating shaft 23. The outer surface of the connecting air box 43 is connected to the right end of the air pipe 42. The connecting hole 44 is opened through the outer surface of the first rotating shaft 23.

[0030] During operation, the hydraulic cylinder 32 moves the clamp 34 via the hydraulic rod 33. The clamp 34 moves the sampling drill barrel 35 and the connecting rod 25 downwards together, inserting the sampling drill barrel 35 into the ground. Simultaneously, the first motor 22 drives the first rotating shaft 23 to rotate. The first rotating shaft 23 drives the connecting rod 25 to rotate via the slide bar 24. The connecting rod 25 drives the sampling drill barrel 35 to rotate, separating the material in the foundation from the foundation. When the foundation sample enters the sampling drill barrel 35, the air inside the sampling drill barrel 35 first enters the first rotating shaft 23 through the connecting rod 25, and then enters the air pipe through the connecting air box 43. In step 42, the air pump 41 connected to it discharges the sample. After the foundation sample is drilled, the second motor 362 drives the eccentric block 364 to rotate through the second rotating shaft 363, causing it to vibrate. The vibration is transmitted to the vibration box 361 through the second motor 362, and then to the sampling drill barrel 35 through the clamp 34. The sampling drill barrel 35 is shaken slightly, causing the sample in the sampling drill barrel 35 to break off from the foundation. Then the air pump 41 draws air through the air pipe 42, causing suction in the sampling drill barrel 35. The first motor 22 stops working, and the hydraulic cylinder 32 and hydraulic rod 33 operate in reverse, causing the sampling drill barrel 35 to be removed from the foundation. Example

[0031] Reference Figure 1 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rotating mechanism 2 further includes a slot 26. The slot 26 is opened on the outer surface of the connecting rod 25. A locking block 27 is rotatably installed on the outer surface of the connecting rod 25. The inner surface of the locking block 27 is engaged with the connecting block 29 through the locking rod 28. The opposite sides of the two connecting blocks 29 are fixedly connected to the outer surface of the connecting rod 25.

[0032] During use, pull out the locking rod 28 to disengage the locking block 27 from the connecting block 29, rotate the locking block 27 to expose the locking groove 26, and then the user rotates the sampling drill barrel 35 to remove the sampling drill barrel 35 from the connecting rod 25. The operation is reversed to quickly install the new sampling drill barrel 35.

[0033] The remaining structure is the same as that in Example 1.

[0034] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the user moves the testing frame 1 above the ground to be tested. Then, the hydraulic cylinder 32 drives the clamp 34 to move via the hydraulic rod 33. The clamp 34 drives the sampling drill barrel 35 and the connecting rod 25 downward together, so that the sampling drill barrel 35 is inserted into the ground. At the same time, the first motor 22 drives the first rotating shaft 23 to rotate. The first rotating shaft 23 drives the connecting rod 25 to rotate via the slide bar 24. The connecting rod 25 drives the sampling drill barrel 35 to rotate, separating the material in the foundation from the foundation. When the foundation sample enters the sampling drill barrel 35, the air in the sampling drill barrel 35 will first enter the first rotating shaft 23 through the connecting rod 25, and then enter the air pipe 42 through the connecting air box 43, and be discharged by the connected air pump 41. After the foundation sample is drilled, the second motor 22 drives the first rotating shaft 23 to rotate. Machine 362 drives the eccentric block 364 to rotate via the second rotating shaft 363, causing it to vibrate. The vibration is transmitted to the vibration box 361 via the second motor 362, and then to the sampling drill barrel 35 via the clamp 34. The sampling drill barrel 35 experiences a small air shake, causing the sample inside the sampling drill barrel 35 to break off from the foundation. Then, the air pump 41 draws air through the air pipe 42, creating suction inside the sampling drill barrel 35. The first motor 22 stops working, and the hydraulic cylinder 32 and hydraulic rod 33 operate in reverse, removing the sampling drill barrel 35 from the foundation. Then, the operator pulls out the clamp rod 28, disengaging the clamp block 27 from the connecting block 29, and rotates the clamp block 27 to expose the clamping groove 26. Then, the operator rotates the sampling drill barrel 35 to remove it from the connecting rod 25, and then reverses the operation to quickly install the new sampling drill barrel 35.
