Description

Technical Field

[0001] The utility model relates to the technical field of road detection, in particular to a road flatness detector. Background Art

[0002] The road flatness is related to the flatness of each structural layer of the road surface, that is, the flatness effect of each layer will be cumulatively reflected on the road surface. Flatness detection is a prescribed standard gauge that intermittently or continuously measures the unevenness of the road surface, that is, the indicator of unevenness, and is an important part of road surface acceptance and maintenance.

[0003] The detection of road surface flatness is usually carried out using a special measuring vehicle, which is equipped with multiple sets of side-by-side detection wheels. When the detection wheels encounter potholes, the detection wheels move upward to squeeze the pressure sensor, thereby observing the pressure change value of the pressure sensor to determine whether the road surface is flat.

[0004] For example, a highway pavement flatness detection device disclosed in authorization announcement No. CN 112501997 B includes a moving mechanism, in which the detection mechanism is slidably connected inside the moving mechanism, and the moving mechanism includes a base plate, a first roller is fixedly installed on the lower surface of the base plate, a strip groove is provided inside the base plate, and limiting slide grooves are provided on the relative inner walls of the strip groove, a data analysis processor, a buzzer and a positioning component are fixedly installed on the upper surface of the base plate, a handrail is also fixedly installed on the upper surface of the base plate, a placement groove is provided on the lower surface of the base plate, a cross plate is fixedly installed inside the handrail, and a first electric telescopic rod is fixedly installed on the lower surface of the cross plate, the telescopic end of the first electric telescopic rod passes through the upper surface of the base plate and extends to the bottom of the base plate, and a brake plate is fixedly installed on the bottom end of the first electric telescopic rod.

[0005] The above disclosed device for detecting the flatness of a highway road surface can obtain the ground flatness information by squeezing a pressure sensor through the up and down fluctuation of a detection wheel and processing the data detected by the pressure sensor into a waveform diagram. However, there are usually gravels on the road surface. When the detection wheel presses over the gravel, abnormal fluctuations will also occur, resulting in an error angle in the detection result. In the prior art, although a small number of devices are equipped with cleaning mechanisms, most of the cleaning mechanisms are directly connected to the detection vehicle, resulting in the vibration generated by the cleaning mechanism when it is working, which affects the detection vehicle and the detection accuracy. In addition, the device cannot automatically mark abnormal road surfaces. When the device detects abnormal data, it will issue a buzzer alarm to notify the user to mark manually. The marking efficiency is low, and some areas are difficult to detect with the naked eye. Utility Model Content

[0006] The purpose of the utility model is to provide a road flatness detector with the advantages of high detection accuracy and high efficiency, which solves the problems in the prior art that the road flatness detection is affected by ground stones or the vibration of the cleaning equipment affects the detection accuracy, and abnormal road surfaces need to be manually marked, affecting the detection efficiency.

[0007] To achieve the above object, the utility model provides the following technical solutions: a road flatness detector, comprising a frame, a detection wheel and a data analysis processor, a cleaning mechanism is arranged at the front end of the frame, and a traction mechanism is arranged at the upper end of the cleaning mechanism;

[0008] The cleaning mechanism is composed of a cleaning frame, a cleaning roller and a motor, the motor and the cleaning roller are connected by a coupling, the traction mechanism is composed of a traction frame, a first shock absorber and a second shock absorber, the traction frame and the cleaning mechanism are elastically connected by the first shock absorber, and the traction frame and the frame are connected by the second shock absorber.

[0009] As a preferred road flatness detector of the utility model, the detection wheel is composed of a universal wheel, a sliding rod, a spring and a pressure sensor, the universal wheel is installed on the lower end surface of the sliding rod, the sliding rod and the pressure sensor are elastically connected by a spring, and the sliding rod is slidably connected to the frame.

[0010] As a preferred road smoothness detector of the utility model, an electric spray gun is provided at the lower end of the frame, the electric spray gun is located at the front end of the universal wheel, and the number of the electric spray guns is equal to the number of the detection wheels.

[0011] As a preferred road flatness detector of the utility model, the first shock absorber is installed between the lower end surface of the traction frame and the upper end surface of the cleaning mechanism, and the second shock absorber is installed between the lower end surface of the traction and the upper end surface of the frame.

[0012] As a preferred road smoothness detector of the utility model, the cleaning roller includes bristles and a rotating shaft, and the bristles are spirally arranged on the surface of the rotating shaft from the center to both sides.

[0013] As a preferred embodiment of the road smoothness detector of the utility model, a roller group is arranged at the bottom of the cleaning frame.

[0014] As a preferred road roughness detector of the utility model, a charging power supply is provided in the data analysis processor, and the charging power supply is electrically connected to the motor and the pressure sensor.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model sets a cleaning mechanism at the front end of the frame, and drives the cleaning roller to rotate through a motor, so that the bristles sweep the road stones to both sides of the road surface to prevent the stones from affecting the detection accuracy. The utility model cooperates with the traction mechanism, and performs shock absorption through the first shock absorber and the second shock absorber. The split design and the double shock absorption structure greatly reduce the influence of the cleaning mechanism on the frame, thereby ensuring the accuracy of the data transmitted by the detection cycle.

[0017] 2. The utility model sets an electric spray gun at the lower end of the frame, receives the pressure sensor data through the data analysis processor for real-time analysis, and when the pressure value is greater than or less than a preset threshold, starts the electric spray gun to spray the ground, thereby automatically marking abnormal road surfaces in real time, greatly improving the detection efficiency of the equipment.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 4 , a road roughness detector, comprising a frame 1, a detection wheel 2 and a data analysis processor 3, a cleaning mechanism 5 is arranged at the front end of the frame 1, and a traction mechanism 4 is arranged at the upper end of the cleaning mechanism 5;

[0024] The cleaning mechanism 5 is composed of a cleaning frame 510, a cleaning roller 520 and a motor 530. The motor 530 is connected to the cleaning roller 520 through a coupling. The traction mechanism 4 is composed of a traction frame 401, a first shock absorber 403 and a second shock absorber 402. The traction frame 401 and the cleaning mechanism 5 are elastically connected through the first shock absorber 403, and the traction frame 401 and the frame 1 are connected through the second shock absorber 402.

[0025] When the device is working, the traction frame 401 of the traction mechanism 4 is fixed to the traction vehicle in front, and the device is moved by the traction vehicle. During the movement, the motor 530 drives the rotating shaft 521 to rotate, thereby driving the bristles 522 on the surface of the rotating shaft 521 to rotate, so that the bristles 522 sweep the road stones to the roadside. When the detection wheel 2 passes through the potholes, the slide rod 202 slides downward, so that the spring 203 undergoes elastic deformation, and the lower end surface of the pressure sensor 204 is subjected to pressure changes. The pressure sensor 204 transmits the pressure data to the data analysis processor 3, so that the data analysis processor 3 performs real-time analysis. When the data is abnormal, the electric spray gun 101 is started to spray the point for later maintenance.

[0026] Furthermore, the detection wheel 2 is composed of a universal wheel 201, a sliding rod 202, a spring 203 and a pressure sensor 204. The universal wheel 201 is installed on the lower end surface of the sliding rod 202. The sliding rod 202 and the pressure sensor 204 are elastically connected through the spring 203. The sliding rod 202 is slidably connected to the frame 1.

[0027] The universal wheel 201 slides up and down through the slide rod 202 to squeeze the spring 203. When encountering a pothole section, the pressure of the spring 203 on the pressure sensor 204 changes. By observing the data of the pressure sensor 204, a road surface smoothness curve is drawn.

[0028] Furthermore, an electric spray gun 101 is provided at the lower end of the frame 1 , and the electric spray gun 101 is located at the front end of the universal wheel 201 . The number of the electric spray guns 101 is equal to the number of the detection wheels 2 .

[0029] After the data analysis processor 3 receives the pressure sensor 204 for analysis and processing, when the data of a certain pressure sensor 204 fluctuates too much, the data analysis processor 3 can start the electric spray gun 101 at the front end of the pressure sensor 204, so as to mark the point where the paint is sprayed, so as to facilitate rework later.

[0030] Furthermore, the first shock absorber 403 is installed between the lower end surface of the traction frame 401 and the upper end surface of the cleaning mechanism 5, and the second shock absorber 402 is installed between the lower end surface of the traction and the upper end surface of the frame 1. The first shock absorber 403 is a hydraulic damping elastic shock absorber, and the second shock absorber 402 is a rubber damping shock absorber.

[0031] The first shock absorber 403 and the second shock absorber 402 are both longitudinal shock absorbers, so that the influence of the cleaning mechanism 5 on the traction frame 401 is reduced by the first shock absorber 403, and the influence of the traction frame 401 on the frame 1 is reduced by the second shock absorber 402, thereby greatly reducing the influence of the vibration of the cleaning mechanism 5 when the frame 1 is working, and improving the stability of the detection.

[0032] Furthermore, the cleaning roller 520 includes bristles 522 and a rotating shaft 521 , the bristles 522 are continuously glued to the surface of the rotating shaft 521 , and the bristles 522 are mirror-shaped spirals from the center to both sides.

[0033] When the motor 530 drives the rotating shaft 521 to rotate, the surface is swept and brushed on the ground, and the spiral bristles 522 structure causes the stones to slide to both sides of the road under the thrust of the bristles 522, thereby preventing them from affecting the equipment detection.

[0034] Furthermore, a roller set 511 is disposed at the bottom of the cleaning frame 510 .

[0035] The cleaning frame 510 slides via the roller set 511 to ensure that the cleaning frame 510 fits the ground, thereby ensuring the cleaning ability of the equipment.

[0036] Furthermore, the data analysis processor 3 is a mobile workstation, and a charging power supply 301 is provided inside the data analysis processor 3 .

[0037] The data analysis processor 3 is electrically connected to the motor 530 , the pressure sensor 204 and the spray gun, and controls the start and stop of the cleaning mechanism 5 . It is also responsible for receiving the data returned by the pressure sensor 204 , processing and analyzing the data, and controlling the start and stop of the electric spray gun 101 .

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
