Description

Technical fields:

[0001] This application relates to the field of intelligent oil spraying and heating technology, and in particular to an intelligent oil spraying and heating system for a tire roller. Background technology:

[0002] A pneumatic tire roller is a machine that uses multiple inflatable rubber tires to compact road surfaces. It is suitable for compacting base layers, subbase layers, and asphalt surface layers of various materials. During highway construction, when using a pneumatic tire roller to compact asphalt surface layers, to prevent the tire treads from sticking to the laid asphalt and affecting the smoothness of the asphalt pavement, vegetable oil is usually sprayed onto the tire treads to prevent adhesion.

[0003] Chinese utility model patent application number 201620011886.4—an automatic oil spraying and heating control device for a tire roller—comprises a connected oil spraying switch and controller, and further includes a temperature sensor, a heating solenoid valve, an oil spraying pump, and an oil spraying solenoid valve, all connected to the controller. The temperature sensor is installed inside the oil spraying tank to monitor the temperature of the oil in the tank. The heating solenoid valve controls the heating of the oil in the tank, and the oil spraying pump and solenoid valve control whether oil is sprayed from the tank. This patented device can ensure the temperature of the sprayed oil, achieving a good oil spraying effect, while also ensuring the compaction performance of the compacted material by the tire roller.

[0004] Existing oil spraying and heating systems, including the aforementioned patents, have a single spraying method, where oil is continuously sprayed through an oil pump. This is not suitable for all road conditions. If the speed of the tire roller is too low, the spray volume will be fixed, resulting in oil waste, reducing the effective utilization rate of oil, and increasing construction costs. If the speed of the tire roller is too high, the predetermined spray volume will result in insufficient spray volume, which will still cause the tire to stick to the asphalt. Utility Model Content:

[0005] To address the aforementioned technical problems, this utility model provides an intelligent oil spraying and heating system for tire rollers. The technical problem it solves is that a single, continuous oil spraying method cannot meet all working conditions, and the low effective utilization rate of oil leads to waste and increased construction costs. The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A smart oil spraying and heating system for a tire roller includes:

[0007] tank;

[0008] The controller is used to acquire input signals and output control signals;

[0009] The oil pump is connected to the oil tank pipeline and is used to draw vegetable oil from the oil tank. The oil pump is electrically connected to the controller and is used to perform the oil spraying work.

[0010] An automatic / manual switch is electrically connected to the controller and is used to switch between automatic and manual modes of the fuel pump. In automatic mode, the fuel pump is always on. In manual mode, the following settings are also provided:

[0011] A speed sensor is used to monitor the vehicle's speed in real time. The speed sensor is electrically connected to the controller, and the controller controls the oil pump to spray the corresponding amount of oil based on the signal from the speed sensor.

[0012] The power supply provides stable electrical energy to drive the entire system to work normally.

[0013] Furthermore, the controller model is PDDJDJNST080HGVD-10.

[0014] The beneficial effects of this utility model are: by setting a speed sensor and an automatic / manual switching switch, different modes can be selected according to construction needs; in automatic mode, oil can be sprayed continuously, which is convenient to operate and suitable for some road conditions; in manual mode, by collecting vehicle speed signals, the amount of oil sprayed by the oil pump can be adjusted to improve the effective use of oil, avoid waste, and reduce construction costs.

[0015] By setting up a heating switch, heater, and temperature sensor, temperature changes can be monitored in real time and the oil can be heated to prevent vegetable oil from crystallizing in winter and clogging the oil pump.

[0016] By setting up a liquid level sensor and alarm indicator, the controller can obtain oil level information in a timely manner and give control signals to prevent the heater from continuing to work when the oil level is too low, which would cause the heating element to burn out, increase the service life of the oil tank and the heating element, and improve safety performance.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0023] An intelligent oil spraying and heating system for a tire roller includes an oil tank 1, a controller 2 for collecting input signals and outputting control signals, an oil pump 3 connected to the oil tank 1 by a pipeline for drawing vegetable oil from the oil tank 1, and an automatic / manual switching switch 4 connected to the controller 2 for switching between automatic and manual modes. In automatic mode, the oil pump is always on. In manual mode, a speed sensor 5 is provided to monitor the vehicle speed in real time. The controller 2 controls the oil pump 3 to spray the corresponding amount of oil based on the signal from the speed sensor 5. A power supply 6 provides stable electrical energy to drive the entire system to work normally. By setting the speed sensor 5 and the automatic / manual switching switch 4, different modes can be selected according to construction needs. In automatic mode, oil can be sprayed continuously, which is convenient to operate and suitable for some road conditions. In manual mode, the amount of oil sprayed by the oil pump 3 is adjusted by collecting the vehicle speed signal, which improves the effective utilization of oil, avoids waste, and reduces construction costs.

[0024] It should be noted that the controller 2 is model PDDJDJNST080HGVD-10; the controller 2 includes a display with display function; the display can display the current temperature value, current liquid level value and current heating status information of the oil in real time, so that the operator can clearly understand the working status of each component in the entire system.

[0025] It should be noted that the oil tank 1 is equipped with a heater 12, which is electrically connected to the heating switch 11 and the controller 2. The heater 12 is used to heat the oil in the oil tank 1.

[0026] It should be noted that the display is equipped with a low-temperature alarm indicator 7, a low oil level alarm indicator 8, a heating indicator 9, and a temperature gauge 10, all electrically connected to the controller 2, to display the real-time operating status of relevant components within the system. The low-temperature alarm indicator 7 indicates whether the oil temperature in the oil tank 1 is below a set threshold. The low oil level alarm indicator 8 warns that the oil level in the oil tank 1 is below the alarm mark, and the flashing of the low-temperature alarm indicator 7 signals to the driver that the oil tank 1 should be heated. The heating indicator 9 indicates whether the heater 12 is in operation, and a flashing of the heating indicator 9 indicates to the driver that the vegetable oil is being heated. The temperature gauge 10 displays the current temperature of the vegetable oil in the oil tank 1 in real time, and the data provided by the temperature gauge 10 allows the driver to determine whether to proceed with the next step.

[0027] It should be noted that the temperature sensor 13, which is electrically connected to the controller 2, is used to monitor the temperature of the oil in real time. The temperature sensor 13 is mainly based on the principles of thermoelectric effect, resistance effect, thermistor effect, thermocouple effect, infrared absorption effect, etc., to convert the temperature signal into an electrical signal.

[0028] It should be noted that the liquid level sensor 14, which is electrically connected to the controller 2, monitors the oil level in the oil tank 1 in real time. The liquid level sensor 14 utilizes the change in capacitance between the sensor housing and the sensing electrode caused by the oil entering the container, and converts this change into a change in current, thereby detecting the position of the oil in the container.

[0029] like Figure 2 As shown in the oil spraying control flowchart, the automatic / manual switch 4 allows for switching between automatic and manual modes. In automatic mode, the switch contacts are not closed, and the low-potential signal cannot be transmitted to the controller 2. The controller 2 continuously outputs a preset control signal to the oil spraying pump 3, and the oil spraying pump 3 remains in operation, with a fixed spraying volume. In manual mode, the switch contacts are closed, and the low-potential signal is transmitted to the controller 2. The controller 2 then receives different frequency signals from the speed sensor 5 and outputs different control signals to the oil spraying pump 3 based on these frequency signals, thereby controlling the spraying volume of the oil spraying pump 3. The speed sensor 5 transmits the frequency signal to the controller 2 in real time based on the detected vehicle speed, enabling the adjustment of the oil spraying volume of the oil spraying pump 3 according to the vehicle speed, improving the effective utilization of vegetable oil and avoiding waste.

[0030] like Figure 3As shown, the controller (2) is model PDDJDJNST080HGVD-10. There is a linear relationship between the speed of the road roller and the amount of oil sprayed. The speed is represented by V and the amount of oil sprayed is represented by L. When V reaches 1km / h, L is 1.8ml; when V reaches 3km / h, L is 5.4ml; when V reaches 4.5km / h, L is 8.1ml. According to the linear relationship diagram of speed-oil spraying, the control logic of PDDJDJNST080HGVD-10 is: L=1.8V.

[0031] The working principle and process of this utility model are as follows:

[0032] The driver can select the oil spraying mode via the automatic / manual switch 4 according to the construction situation. When the automatic mode is selected, the switch contacts are not closed, the controller 2 does not receive a low potential signal, the frequency signal of the speed sensor 5 is not transmitted to the controller 2, and the controller 2 continuously transmits the same frequency signal to the oil pump 3 according to the internal value. The oil pump 3 will continuously spray oil onto the tires at a certain frequency, and the amount of oil sprayed is fixed within a certain period of time. When the manual mode is selected, the switch contacts are closed, the controller 2 begins to receive the frequency signal of the vehicle's running speed monitored in real time by the speed sensor 5, and the controller 2 then calculates the control signal for controlling the operation of the oil pump 3 through the internally set logic control program code based on the received frequency signal, and then transmits the control signal to the oil pump 3. The oil pump 3 adjusts the amount of oil sprayed according to the received control signal to match the amount of oil sprayed with the vehicle speed.

[0033] Turn on the power supply 6. The temperature sensor 13 monitors the temperature of the vegetable oil in the oil tank 1 in real time. The temperature sensor 13 transmits the detected temperature signal to the controller 2. The controller 2 sends a signal back to the temperature instrument 10, which displays the vegetable oil temperature in real time. If the oil temperature is lower than the preset value, the controller 2 sends a signal to the low-temperature alarm indicator 7, which then flashes. At this time, turn on the heating switch 11, connecting the heating circuit. The controller 2 outputs a signal to the heater 12, which starts working. Simultaneously, the temperature instrument 10 continuously displays the vegetable oil temperature, and the heating indicator 9 remains constantly lit. When the oil temperature exceeds the preset stop temperature value, the controller 2 sends a signal to the heater 12. A stop signal is sent to heater 12, causing it to stop working and the heating indicator light 9 to turn off. As the vehicle moves, controller 2 controls the fuel pump 3 to spray fuel, and the level sensor 14 starts working to monitor the fuel level in real time. When the fuel level is lower than the system's set alarm limit, the level sensor 14 transmits a level signal to controller 2. Upon receiving the signal, controller 2 outputs a control signal to the fuel level alarm indicator light, fuel pump 3, and heater 12. The low fuel level alarm indicator light 8 flashes, indicating to the driver that fuel tank 1 needs refueling, and fuel pump 3 stops working. If heater 12 is heating, it will also stop. Once fuel tank 1 is full, the low fuel level alarm indicator light 8 turns off.
