Description

[0002] In road construction, asphalt paving is an important construction link. Currently, the existing asphalt paving equipment has the problem of easy deviation during paving, which can lead to inaccurate paving width, irregular edges, and other situations.

[0024] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0025] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of an asphalt paving equipment provided by an embodiment of the present application, and the asphalt paving equipment 000 can include: a device body 100, a steering structure 200, and an intelligent control assembly 300. The device body 100 serves as the basic framework of the entire device, and carries and supports other components. The steering structure 200 and the intelligent control assembly 300 cooperate with each other to realize precise steering and intelligent control of the device, so as to improve the quality and efficiency of asphalt paving.

[0026] In the present application, as shown in Figure 1 , the steering structure 200 includes a steering controller 201, a steering wheel 202, and a sensor group 203. The steering controller 201 includes a steering control assembly 201a and a steering rod 201b; the steering rod 201b is fixedly connected with the steering wheel 202, and the steering control assembly 201a is used to control the rotation of the steering rod 201b. In this way, flexible steering of the asphalt paving equipment 000 can be realized through the steering control assembly 201a. Here, the cooperation of the steering controller 201 and the steering wheel 202 has multiple possible implementation manners.

[0027] In a possible implementation, the steering controller 201 can be a hydraulic steering controller. The steering control assembly 201a can further include a steering cylinder, a connecting oil pipe, a steering pump, and a steering controller. The steering rod 201b can be fixedly connected with the steering wheel 202, so that when the steering rod 201b rotates, the steering wheel 202 can be directly driven to steer.

[0028] For example, the steering cylinder can be connected with the steering pump through the connecting oil pipe. When the steering pump works, hydraulic oil is delivered to the steering cylinder through the connecting oil pipe to provide power for steering. The steering controller is movably connected with the steering pump, and functions to control the flow direction and flow rate of the hydraulic oil. The steering controller can control the rotation of the steering rod 201b, thereby realizing the steering operation of the steering wheel 202.

[0029] In another possible implementation, the steering controller 201 can be an electric motor engine. In this case, the output shaft of the electric motor engine is fixedly connected with the steering rod 201b, so as to control the rotation of the steering rod 201b.

[0030] In the present application, as shown in Figure 1 The sensor group 203 can include an angle sensor 203a, a laser ranging sensor 203b, and a gyroscope sensor 203c. The angle sensor 203a is located on both sides of the steering wheel 202, and is used to monitor the rotation angle of the steering wheel 202 in real time, and provide the angle information of the steering wheel 202 for the intelligent control assembly 300. The laser ranging sensor 203b is in a plurality, and is uniformly distributed along the edge of the equipment body 100. In this way, the laser ranging sensor 203b can measure the distance between the equipment and the surrounding objects (such as the edge of the road surface, obstacles, etc.), and provide data support for the steering and travel path planning of the equipment. The gyroscope sensor 203c is arranged at the bottom of the equipment body 100, and can measure the steering angle and angular velocity of the equipment, and help the intelligent control assembly 300 more accurately master the steering state of the equipment.

[0031] Through the design of such a steering structure 200, combined with the cooperative work of multiple sensors, the equipment can realize more accurate steering control. The angle sensor 203a feeds back the angle of the steering wheel 202 in real time, the laser ranging sensor 203b monitors the surrounding environment, and the gyroscope sensor 203c accurately measures the steering angle and angular velocity. These information all provide accurate basis for the steering controller 201d to control the rotation of the steering rod 201e, so that the equipment can accurately steer in a complex construction environment, improve the accuracy of asphalt paving, reduce the deviation of asphalt paving caused by inaccurate steering, and ensure the quality of road construction.

[0032] In the present application, please refer to Figure 1The intelligent control assembly 300 includes a control element 301 and a driving motor 302. The control element 301 is electrically connected with the sensor group 203, and the sensor group 203 emits electric signals to the control element 301 during work. After the control element 301 obtains the electric signals, the control element 301 controls the driving motor 302 to drive the steering control assembly 201 to operate according to a preset program and algorithm. For example, when the steering controller 201 is a hydraulic steering controller, the control driving motor 302 can provide driving force to the steering controller. The driving motor 302 adjusts the size and direction of the output power under the control of the control element 301, thereby driving the steering controller to act, and realizing accurate control of the steering structure 200.

[0033] In summary, the present application provides an asphalt paving device including a device body, a steering structure, and an intelligent control assembly. The device body serves as a basic framework, provides stable bearing and support for other components, guarantees the stability of the overall structure of the device, and is the cornerstone of normal operation of the device. The close cooperation of the steering structure and the intelligent control assembly realizes accurate steering and intelligent control of the device, greatly improving the quality and efficiency of asphalt paving. In the steering structure, multiple sensors work cooperatively, the angle sensor monitors the rotation angle of the steering wheel in real time, the laser ranging sensor measures the distance between the device and the surrounding objects, and the gyroscope sensor measures the steering angle and angular velocity of the device, providing comprehensive and accurate data support for steering control. These information enables the steering controller to accurately control the rotation of the steering lever, and then accurately steer the steering wheel, so that the device can accurately operate according to the predetermined route in complex construction environment, greatly improving the accuracy of asphalt paving, effectively reducing the paving deviation caused by inaccurate steering, and guaranteeing the quality of road construction. The control element in the intelligent control assembly accurately controls the driving motor to provide driving force to the steering controller according to the electric signals emitted by the sensor group and the preset program and algorithm. The driving motor can flexibly adjust the size and direction of the output power, realize accurate control of the steering structure, further enhance the accuracy and stability of steering, make the device operation more intelligent and accurate, improve the overall performance of the device, and ensure efficient and high-quality completion of asphalt paving work

[0034] In the embodiments of the present application, please refer to Figure 2 , Figure 2is a schematic diagram of a matching relationship of an intelligent control assembly provided by an embodiment of the present application. The intelligent control assembly 300 can further include a data processing assembly 303, which is electrically connected with the control element 301. The control element 301 can pre-process the electrical signal transmitted by the sensor group 203, remove noise and interference signals, generate a pre-processed signal, and then transmit the pre-processed signal to the data processing assembly 303. The data processing assembly 303 analyzes the pre-processed signal. For example, the data processing assembly 303 can perform fusion processing on sensor data, calculate the driving trajectory and steering trend of the device, and transmit the analysis result back to the control element 301. Based on the analysis result, the control element 301 can more accurately control the driving motor 302, and thus more accurately control the steering controller 201d, to achieve more intelligent and accurate steering control.

[0035] The design of the intelligent control assembly 300 enables the steering control of the device to be automated and intelligent. The control element 301 controls the driving motor 302 according to the electrical signal of the sensor group 203, and the driving motor 302 accurately drives the steering controller, thereby improving the response speed and control accuracy of steering. The addition of the data processing assembly 303 further improves the processing capability of the intelligent control assembly 300 for sensor data, and can analyze and optimize complex sensor data to provide more accurate decision basis for steering control, thereby better adapting to various construction environments and working conditions and improving the overall performance and construction efficiency of the device.

[0036] It should be noted that, as Figure 3 indicated, Figure 3 is another structural schematic diagram of an asphalt paving device provided by an embodiment of the present application. The asphalt paving device 000 can further include an environment monitoring assembly 400, which can include a temperature and humidity sensor 401 and a wind speed sensor 402. The temperature and humidity sensor 401 is located at the top of the device body 100, which can more accurately measure the air temperature and humidity of the construction site, avoiding the influence of the heat and humidity generated by the device itself on the measurement result. The wind speed sensor 402 is located at the highest point of the top of the device, which can minimize the interference of surrounding objects on wind speed measurement and obtain more accurate wind speed data.

[0037] The environmental monitoring assembly 400 can monitor the temperature, humidity and wind speed information of the construction environment in real time. The temperature and humidity data help the construction personnel understand the influence of the environment on the performance of asphalt, for example, when the humidity is high, the heating temperature and paving speed of the asphalt can be adjusted appropriately to ensure that the asphalt can be well bonded on the road surface. The wind speed data can be used to adjust the relevant parameters of the paving operation, such as in windy weather, the discharge speed and paving width of the paver can be reasonably adjusted to avoid the asphalt being blown away, and the uniformity and quality of the asphalt paving are ensured. Through the monitoring of environmental parameters and corresponding adjustment, the quality of asphalt paving is improved, and the adverse effects of environmental factors on construction are reduced.

[0038] As shown in Figure 3 , the asphalt paving equipment 000 can include a paving device 500, which can be fixedly connected with the equipment body 100. In this way, the paving device 500 can stably cooperate with the equipment body 100 to realize the paving of asphalt. The paving device has a paving plate 501. Positioning assemblies 502 are distributed on both sides of the paving plate 501, and each positioning assembly 502 includes two position sensors that are electrically connected with the intelligent control assembly 300.

[0039] In this way, the positioning assembly 502 can monitor the position information of the paving plate 501 in real time and transmit the information to the intelligent control assembly 300. The intelligent control assembly 300 adjusts the driving direction of the equipment and the working state of the paving device according to the data of the position sensor, ensures that the paving plate 501 always maintains at the predetermined paving position, improves the straightness and width accuracy of asphalt paving, avoids the deviation and deviation in the paving process, and guarantees the flatness and quality of road paving.

[0040] In the embodiments of the present application, please refer to Figure 3 , the asphalt paving equipment 000 further includes a thickness detection assembly 600, which is composed of an ultrasonic sensor 601 for measuring the road surface basis flatness and height before paving and a laser displacement sensor 602 for detecting the thickness of the paved asphalt during paving. The ultrasonic sensor 601 is located on the side of the equipment body 100 close to the paving plate, so that it can measure the road surface basis flatness and height of the area to be paved in advance before paving when the equipment is moving forward. The laser displacement sensor 602 is located on the side of the paving plate close to the ground, and can measure the thickness of the paved asphalt in real time.

[0041] The thickness detection assembly 600 is arranged to realize accurate control of the asphalt paving thickness. Before paving, the ultrasonic sensor 601 measures the road surface foundation data to provide a basis for adjusting the initial height of the paving plate 501; during paving, the laser displacement sensor 602 monitors the thickness of the paved asphalt in real time, and the intelligent control assembly 300 adjusts the height of the paving plate 501 in a timely manner according to the data, thereby ensuring the uniformity of the asphalt paving thickness and improving the bearing capacity and service life of the road.

[0042] It should be noted that the inside of the device body 100 is fixedly installed with a telescopic connecting rod, and the lower end of the telescopic connecting rod is fixedly installed with a dust sweeper. The arrangement of the dust sweeper can sweep the road surface before paving the asphalt, remove dust and sundries on the road surface, ensure the cleanliness of the road surface, make the asphalt better adhere to the road surface, improve the bonding effect of the asphalt and the road surface, and further improve the quality of road paving.

[0043] In the embodiment of the present application, please refer to Figure 4 , Figure 4 is a schematic view of a steering rod and a steering wheel provided by the embodiment of the present application. The central axis of the steering rod 201e in the steering structure 200 passes through the center of the steering wheel 202.

[0044] This layout makes the steering rod 201e more uniform and stable when turning to drive the steering wheel 202 to turn, reduces the eccentric force in the steering process, improves the steering accuracy and stability of the steering wheel 202, further ensures the stability of the device during driving and steering, and is conducive to improving the accuracy and quality of asphalt paving.
