Description

Technical Field

[0001] The present invention relates to a road maintenance technology, and in particular to an intelligent paving device for road anti-cracking stickers. Background Art

[0002] Currently, vehicle loads are gradually increasing, and due to the long service life of earlier-constructed concrete pavements, most concrete pavements are experiencing serious damage before reaching their design lifespan, especially cement concrete pavements in highway service areas. Therefore, most cement concrete pavements urgently need to be overlaid with an asphalt layer. To prevent reflective cracks in the overlay, one of the most effective solutions is to apply road crack prevention tape between the asphalt overlay and the existing concrete pavement.

[0003] Whether it's self-adhesive or hot-applied road anti-cracking tape, the traditional construction process involves spreading tack coat oil on the milled concrete pavement. Construction workers then draw lines and measure on-site to determine the direction and placement of the tape. They then align the tape's end with the starting point and begin laying it sequentially. A roller then slowly rolls over the applied tape. This method is inefficient, difficult to control, and requires close proximity between construction workers and the paver, posing safety risks. Summary of the Invention

[0004] The main purpose of the present invention is to provide an intelligent paving device for road anti-cracking tape, which realizes high-precision, fully automatic and unmanned construction of road anti-cracking tape, ensures that the paving direction and position are consistent with the construction plan, and reduces the input of construction personnel and energy consumption.

[0005] The technical solution adopted by the present invention is: an intelligent paving device for road anti-cracking tape, wherein the lower end of the intelligent paving device is provided with two solid rolling wheels, and the two rolling wheels are connected by a mechanical sensor arm and rotate in the same direction and simultaneously during operation; A circular roller is provided on the upper pole of the intelligent laying device for placing the anti-cracking patch material to be laid. A conductor sag detection system is provided inside the intelligent laying device, and the conductor sag detection system is electrically connected to the computer terminal. A timer switch is provided on the outside of the intelligent laying device, which can be controlled manually or by remote control to set the working time of the intelligent laying device. The intelligent paving device is equipped with a GPS navigation system, which is electrically connected to the computer terminal to achieve remote operation and real-time tracking of the construction path; The intelligent paving device is provided with a signal receiving antenna; A solar panel is provided on the top of the intelligent paving device to provide working power for the intelligent paving device; A power control system is provided at the bottom of the intelligent paving device.

[0006] Furthermore, a transmission chain is provided between the two rolling wheels to connect them, and the timing switch is electrically connected to the power control system at the bottom of the intelligent paving device and is electrically connected to the control motor of the transmission chain.

[0007] Furthermore, the solar panel on the top of the intelligent paving device is electrically connected to the power control system, and the power control system also includes a blower, exhaust holes, and an energy conversion system inside the device. The energy conversion system is used to convert solar energy into electrical energy.

[0008] Furthermore, the GPS navigation system and signal receiving antenna of the intelligent paving device are both detachably installed. When working, the GPS navigation system assists in completing positioning through the server, computer, Beidou positioning module, control module, and wake-up module.

[0009] Furthermore, the power source of the conductor sag online monitoring system is the energy conversion system of the intelligent laying device, and the conductor sag online monitoring system includes conductors, utility poles and an automatic alarm system.

[0010] Furthermore, the circular roller on the upper part of the intelligent paving device is a non-fixed device, which can rotate clockwise or counterclockwise and is used to wrap the anti-cracking tape material around the pole in sequence along the shape of the roller, with the asphalt bonding layer of the anti-cracking tape facing the outer layer.

[0011] Furthermore, the length of the upper pole of the intelligent paving device and the two rolling wheels are the same.

[0012] Furthermore, the control circuit of the GPS navigation system and the signal receiving antenna includes: Signal receiving and processing part, including: GPS antenna: used to receive radio frequency signals transmitted by satellites; Frequency synthesizer: used to generate a stable local oscillation signal, mix it with the received signal, and achieve frequency synchronization; Frequency converter: used to convert the high-frequency signal received by the antenna into an intermediate frequency or baseband signal for subsequent processing; Module converter: an analog-to-digital converter used to convert analog signals into digital signals for analysis by the microprocessor; Control and data processing part, including: Microprocessor: used for core control unit, processing digital signals, demodulating GPS data, and coordinating the work of various modules; Satellite parameter display: used to display the analyzed satellite information, which is an LCD or LED module; Power management section, including: Power supply / battery: used to provide system power; Power protector: used to integrate overvoltage and overcurrent protection components to ensure circuit safety; Capacitor C1: Located at the power input end, used for filtering and stabilizing voltage and suppressing high-frequency noise; Resistors R2 and R3 are used for impedance matching in the signal path or as voltage divider / current limiting resistors in the power path.

[0013] Advantages of the present invention: In the present invention, the anti-cracking patch material to be spread is coiled flat on the circular roller of the upper frame of the machine body. When the anti-cracking patch material is pulled downward, the material moves downward along the roller until the end of the material is in contact with the ground to be spread. Then, the switch button is turned on to start the anti-cracking patch spreading. During the paving process, the sag online monitoring system in the middle of the machine body can detect whether the anti-cracking patch material compacted by the first front and rear rollers has abnormalities such as curling or wrinkles through a precise displacement measurement system with the ground. If abnormal sag occurs, the online monitoring system will automatically alarm, and the computer terminal connected to it will also display an error prompt. If there is no abnormality, the roller on the rear side of the machine body will re-compact the anti-cracking patch to ensure close adhesion to the original road surface.

[0014] The circular roller of the paver can generate downward force on the anti-cracking tape on the roller through the bonding force between the asphalt bonding layer of the anti-cracking tape and the road surface, thereby realizing automatic material transportation and automatic paving. Compared with manual paving by construction workers in front of the paving device, it not only reduces manpower input, but also avoids safety accidents that may occur when construction workers and the paver work in the same direction.

[0015] The power source for the construction process of the intelligent paving method for road anti-cracking tape of the present invention is solar energy, which greatly reduces environmental pollution and saves natural resources.

[0016] The present invention is combined with a GPS navigation system to achieve remote construction monitoring, high precision, high efficiency, and laying of road anti-cracking stickers in a specified direction.

[0024] The solar panel on top of the intelligent paving device is electrically connected to the power control system, which also includes a blower, exhaust holes, and an energy conversion system inside the device. The energy conversion system is used to convert solar energy into electrical energy.

[0025] The GPS navigation system and signal receiving antenna of the intelligent paving device are both detachably installed. When working, the GPS navigation system assists in completing positioning through the server, computer, Beidou positioning module, control module, and wake-up module.

[0026] The power source of the conductor sag online monitoring system is the energy conversion system of the intelligent laying device. The conductor sag online monitoring system includes conductors, utility poles and an automatic alarm system.

[0027] The circular roller on the upper part of the intelligent paving device is a non-fixed device and can rotate clockwise or counterclockwise. It is used to wrap the anti-cracking patch material on the rack in sequence along the shape of the roller, with the asphalt bonding layer of the anti-cracking patch facing the outer layer.

[0028] The length of the upper pole of the intelligent paving device is the same as that of the two rolling wheels.

[0029] Wherein, 1 is a solar panel 1, which is used to absorb light energy when the paving device is working or on standby.

[0030] Conductor sag online monitoring system (outside) 2, through the vertical distance between the arc conductor and the ground, is used to detect the flatness of the anti-cracking tape after compaction by the front roller when laying anti-cracking tape materials.

[0031] The cylindrical roller 3 is used to place the anti-cracking film coil to be laid.

[0036] The blower 9 inside the device draws air into the device through centrifugal force and quickly discharges it, thereby regulating the temperature of the device and preventing the paver from malfunctioning and becoming dangerous due to excessive temperature when the device is working.

[0037] The conductor sag online monitoring system (inside) 10 is installed in the middle of the front and rear rolling wheels.

[0038] The rolling wheel transmission chain 11 is used to connect the front and rear rolling wheels, the conductor sag online monitoring system, the internal blower, the power control system, etc.

[0039] The exhaust hole 12 is used to discharge the air sucked in by the above 9.

[0040] The energy conversion system 13 is used to convert the light energy of the solar panel into electrical energy for the operation of the device.

[0041] The working principles of the 7GPS navigation system and 8GPS signal receiving antenna in this embodiment are as follows: Figure 3 As shown, the GPS navigation system contains a vibration sensor and a Hall effect sensor. These two sensors are connected to four modules: the wake-up module, the control module, the GPRS module, and the server. The control module and the GPRS module are responsible for receiving information from the eight GPS signal receiving antennas, then passing the received signals to the GPS module for processing. Finally, the processed information is sent to the server, which is generally a computer. The power module controls the operation and suspension of all these modules.

[0042] In this embodiment, the conductor sag online monitoring system (inside) 10 has a specific working principle as follows: Figure 4 As shown, the system has two poles perpendicular to the ground on both sides, and an arc-shaped conductor is connected between the two poles, which is the sag. The minimum distance change between the sag and the paving surface is used to determine whether the laid anti-cracking material has wrinkles, curling, etc. If the thickness difference is greater than 3 mm, an alarm will be given at the conductor part, and you can choose to stop working.

[0043] The circuit control diagram of the GPS navigation system 7 and the GPS signal receiving antenna 8 in this embodiment is shown in FIG. Figure 5 As shown in the figure, the circuit diagram describes the composition and signal processing flow of the GPS antenna system. The functions and connection relationships of each component are as follows: The first part is the signal reception and processing part, including: GPS antenna: receives radio frequency signals transmitted by satellites; Frequency synthesizer: Generates a stable local oscillation signal for mixing with the received signal to achieve frequency synchronization; Frequency converter: down-converts the high-frequency signal received by the antenna to an intermediate frequency or baseband signal for subsequent processing; Modular converter: This may be an analog-to-digital converter (ADC), which converts analog signals into digital signals for analysis by the microprocessor.

[0044] The second part is the control and data processing part, including: Microprocessor: core control unit, processes digital signals, demodulates GPS data (such as time, longitude and latitude), and coordinates the work of various modules; Satellite parameter display: displays parsed satellite information (such as signal strength, number of satellites, and positioning status), which may be an LCD or LED module.

[0045] The third part is the power management part, including: Power supply / battery: provides system power supply; Power protector: integrated overvoltage and overcurrent protection components (such as TVS diodes and fuses) to ensure circuit safety; C1 (capacitor): Located at the power input, used for filtering and stabilizing voltage, and suppressing high-frequency noise; R2, R3 (resistors): May be used for impedance matching in the signal path, or as voltage divider / current limiting resistors in the power path.

[0046] In this embodiment, C1 and the power protector reduce the impact of power supply noise on high-frequency signals. The microprocessor may use sleep mode to save power. Each functional module (such as frequency conversion and display) is designed independently to facilitate debugging and maintenance.

[0047] In this embodiment, the specific working principle is: when light shines on the solar cell panel, the light energy is absorbed by the semiconductor material on the panel, and the energy conversion system causes electrons to migrate to form electrical energy.

[0048] The construction process of the intelligent paving device for road crack resistance of the present invention is as follows: Figure 6 The specific construction method is as follows: First, the anti-cracking tape material to be laid is rolled around three circular rollers (with the asphalt bonding layer of the anti-cracking tape facing outward). Then, the end of the material is pulled down to the paving starting point to align with the road surface to be paved. Then, the GPS system and the connected computer terminal at seven locations are turned on. After turning on the power button of the device at five locations, paving begins. If an alarm sounds at any of the ten locations during the paving process, return to the second step above, re-place the anti-cracking tape material, and re-pave. If there is no alarm, paving is complete.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
