Description

Technical Field

[0001] The utility model relates to the technical field of road surface compaction detection, in particular to a device for quickly detecting the compaction of a roadbed or road surface. Background Art

[0002] When testing the compaction of highway subgrade and pavement, it is often necessary to use a drilling sampling device to perform core sampling.

[0003] The existing drilling sampling device consists of a drill rig that can move up and down and a detachable drill barrel. There is a crushing drill at the bottom of the drill barrel, which can crush the road surface and penetrate into the road surface. The drill barrel is a hollow structure and can penetrate into the road surface to obtain a sample core. The sample core is then taken out and analyzed and tested to obtain the compaction degree of the highway road surface.

[0004] However, when testing the compaction of a section of roadbed and pavement, it is necessary to take samples at multiple points on the road surface, and sampling needs to be performed at each point. It takes a certain amount of time to obtain each core sample. Therefore, in the detection of large-area roads, its work efficiency is relatively low, and the speed of obtaining the compaction results of the road surface is slow, which requires a certain amount of time. Therefore, a new roadbed and pavement compaction rapid detection device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0006] Therefore, one purpose of the utility model is to provide a device for quickly detecting the compaction degree of roadbed and pavement, so as to solve the problems mentioned in the background technology and overcome the shortcomings existing in the prior art.

[0007] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a roadbed and pavement compaction rapid detection device, comprising a mobile platform, a handle, a fixed sleeve, and a display, wherein mobile wheels are installed at the four corners of the bottom surface of the mobile platform, and a handle is fixedly connected to the edge of the top surface of the mobile platform;

[0008] A fixing sleeve is fastened on the handle, and a display screen is fixedly connected to one side of the fixing sleeve;

[0009] A battery is installed on the top surface of the mobile platform, a joint is fixedly connected to the front edge of the top surface of the mobile platform, a frame is fixedly connected to the front of the joint, a positive and negative screw rod is movably connected to the inner side of the frame, a slider is threadedly connected to the positive and negative sections of the positive and negative screw rods, and a carrier plate is fixedly connected to the bottom of the slider;

[0010] The bottom of the carrier plate is fixedly connected with a radar, and the distance between the radars is adjustable;

[0011] The output end of the radar is connected to the display screen line, the inner side of the frame is fixedly connected to a guide rail, and the slider is movably connected to the guide rail;

[0012] The ends of the forward and reverse screw rods are fixedly connected with a hand wheel, a locking pin is threadedly connected to the hand wheel, and the end of the locking pin abuts against the end surface of the frame.

[0013] Preferably, any of the above schemes is that the moving wheels on the bottom surface of the moving platform are divided into two universal front wheels and two linear rear wheels, and the fixing sleeve is fastened to the outer surface of the handle by screws.

[0014] Adopting the above technical solution: this device is specially used for roadbed and pavement compaction detection, and the specific detection mechanism is radar. When this device is working, the staff only needs to push it along the road surface, and the operation is simple.

[0015] Its working principle is as follows. The radar equipment will emit high-frequency electromagnetic wave signals to the roadbed. When these signals encounter the interface of different media (such as soil, gravel, asphalt, etc.), part of the signals will be reflected back. The receiver in the radar will capture these reflected signals, which contain information about the structure, density and compaction of the roadbed material. The received reflected signal will go through a series of signal processing steps, including filtering, amplification, digitization, etc., to extract useful information. This process is completed in the radar machine. By analyzing the intensity, frequency, phase and other parameters of the reflected signal, the medium characteristics, layered structure and compaction of the roadbed can be inferred. The processed data will be transmitted to the display screen installed at the handle. The display screen displays information such as the compaction, thickness, material distribution and other information of the roadbed in the form of graphics, numbers or tables. The operator can intuitively observe and analyze these data to judge the compaction quality of the roadbed.

[0016] Preferably, any of the above schemes is that the display screen is electrically connected to the battery, and the bending angle of the connector is ninety degrees.

[0017] Adopting the above technical solution: One of the characteristics of this device is the rapid detection of roadbed and pavement compaction. Compared with the traditional core drilling sampling method for detecting the compaction of roadbed and pavement, this device can quickly scan the entire road surface area during movement, without the need for point-by-point sampling like the core drilling method. Therefore, it can significantly improve work efficiency and save a lot of time when detecting large areas of road surface. Its main characteristics are fast and efficient.

[0018] Preferably, any of the above solutions is that the joint is riveted or connected to the top surface of the mobile platform by screws, and the joint is riveted or connected to the frame by screws.

[0019] Adopting the above technical solution: the core structure of this device is: joint, frame, forward and reverse screw rods, slider, carrier plate, radar, guide rail, hand wheel, locking pin. The core advantages of this device are: adopting the dual radar design, during the movement of the device, the compaction of the roadbed and pavement is detected at the same time, when the hand wheel is rotated forward and reverse, the forward and reverse screw rods can be reversed, thereby driving the two sliders to move in the opposite direction on the forward and reverse screw rods, so that the distance between the two radars can be adjusted, and when detecting the compaction of the pavement, it can adapt to the detection requirements of different pavement materials and compaction. According to the different pavement materials and structures, the distance between radars can be adjusted to obtain more accurate compaction data. This flexibility gives the device a wider range of applications;

[0020] By adjusting the radar spacing, the propagation path of radar waves in the road surface structure can be optimized, signal interference and attenuation can be reduced, thereby improving detection accuracy. In addition, the dual radar configuration can also achieve cross-validation to further ensure the accuracy of the detection results.

[0021] Preferably, according to any of the above solutions, the cross-sectional shape of the frame is U-shaped, and the frame is located at the front end of the mobile platform.

[0022] Preferably, from any of the above schemes, the forward and reverse screw rods are located on one side of the guide rail, and the model of the radar is RQT800.

[0023] Preferably, any of the above solutions has an end portion of the locking pin fixedly connected to a knob, and the locking pin can lock the angle of the hand wheel.

[0024] By adopting the above technical solution: after the locking pin is tightened, the angle of the hand wheel can be locked and the position of the radar on the guide rail can be locked.

[0025] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0026] The device for rapid detection of compaction of roadbed and pavement adopts a dual-radar design through the coordinated arrangement of joints, frames, forward and reverse screw rods, sliders, carrier plates, radars, guide rails, hand wheels, and locking pins. During the movement of the device, the compaction of the roadbed and pavement is detected simultaneously. When the hand wheel is rotated forward and reverse, the forward and reverse screw rods can be reversed, thereby driving the two sliders to move in opposite directions on the forward and reverse screw rods, so that the distance between the two radars can be adjusted. When detecting the compaction of the pavement, it can adapt to the detection requirements of different pavement materials and compaction. According to different pavement materials and structures, the distance between radars can be adjusted to obtain more accurate compaction data. This flexibility gives the device a wider range of applications;

[0027] By adjusting the radar spacing, the propagation path of radar waves in the road surface structure can be optimized, signal interference and attenuation can be reduced, thereby improving detection accuracy.
