Description

Technical Field

[0001] This invention belongs to the field of cutting machine technology, and in particular relates to an automatic balancing system for a road cutting machine. Background Technology

[0002] Road cutting machines are tools used in road maintenance and construction. Their main function is to cut grooves in the road surface, creating a thin line with a depth ranging from 100mm to 400mm. They are commonly used on cement and asphalt roads. During operation, due to uneven road surfaces, the machine body will tilt with the road surface. However, the saw blade is already tens of centimeters below the road surface before the machine body tilts. Therefore, when the machine body tilts, the saw blade cannot tilt with the machine body due to resistance, which can cause the saw blade to jam. This affects the normal progress of road cutting operations and may even damage the saw blade, increasing maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic balancing system for road cutting machines to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An automatic balancing system for a road cutting machine includes: a control panel and sensors and solenoid valves electrically connected to a controller inside the control panel, wherein the solenoid valves are connected in parallel with two hydraulic cylinders;

[0006] The sensor is installed on the steering box of the cutting machine. The solenoid valve is installed on one side of the upper part of the support frame of the cutting machine and connected in series with the oil tank of the cutting machine through an oil pump. The two rear sides of the support frame are rotatably connected to the chassis at its bottom. The two sides of the middle part are connected to the chassis through two hydraulic cylinders and the two hydraulic cylinders are symmetrically arranged.

[0007] The sensor is used to detect the tilt angle of the steering box and transmit the detected signal to the controller; the controller issues a command to the solenoid valve based on the signal detected by the sensor or the signal received by the control panel, thereby controlling the extension and retraction of the hydraulic cylinder to keep the steering box and the saw blade on the cutting shaft horizontally balanced.

[0008] As a further improvement of the present invention, the control panel is provided with a power button, an automatic calibration button, a sensitivity increase button, a sensitivity decrease button, an automatic button, a left increase / right decrease button, a left decrease / right increase button, and a display screen.

[0009] As a further improvement of the present invention, the sensor is a horizontal sensor.

[0010] As a further improvement of the present invention, a motor with an output shaft that moves forward is mounted on the upper rear side of the support frame via a motor mount, and a transition shaft that extends horizontally in the left and right direction is provided on the upper front side. The transition shaft is connected to the output shaft of the motor via the steering box.

[0011] The two ends of the transition shaft are connected to the two ends of the cutting shaft of the cutting machine via a transmission belt.

[0012] As a further improvement of the present invention, two symmetrical connecting rings are coaxially provided on the transition shaft, the ends of the connecting rings are connected to the cutting shaft through a fixing frame, and the front end of the fixing frame is connected to the saw blade baffle.

[0013] As a further improvement of the present invention, the chassis is also provided with a control box. The upper part of the control box is provided with a display screen for displaying the cutting rate and a voltmeter for displaying the voltage value; the middle part is provided with a power indicator light and a rate regulator; and the lower part is provided with an emergency stop button, a remote control trigger, a front and rear regulator, a left and right regulator, an up and down regulator, and a split regulator.

[0014] As a further improvement of the present invention, the chassis of the cutting machine is a tracked chassis.

[0015] As a further improvement of the present invention, the chassis of the cutting machine is a tracked chassis.

[0016] The beneficial effects of adopting the above technical solution are as follows:

[0017] This invention includes a control panel, sensors, solenoid valves, and hydraulic cylinders. Sensors are mounted on the steering box to detect its tilt angle. Solenoid valves, installed on one side of the upper part of the support frame and connected in series with an oil tank, supply oil to the hydraulic cylinders. The rear ends of the support frame are rotatably connected to the chassis at its bottom, and the middle two sides are connected to the chassis via two hydraulic cylinders. Based on the signal value detected on the steering box, the extension and retraction of the hydraulic cylinders can be manually or automatically controlled. This causes the support frame to rotate upwards or downwards around its rear end according to the extension and retraction of the hydraulic cylinders, thereby raising or lowering the support frame, the steering box on the support frame, and the saw blade connected to the steering box until the sensor detects that the steering box is in a horizontal state, completing the automatic leveling of the saw blade.

[0018] The automatic balancing system provided by this invention can keep the saw blade horizontal and balanced no matter how the machine body is tilted, effectively solving the problem of saw blade jamming caused by machine body tilting, improving the efficiency of road cutting, and reducing the maintenance and replacement costs of saw blade damage due to jamming.

[0023] To better understand the purpose, structure, and function of this invention, a clear and complete description of the invention is provided below in conjunction with the accompanying drawings.

[0024] like Figures 1-3 An automatic balancing system for a road cutting machine is shown, comprising: a control panel 1 and sensors 2 and solenoid valves 3 electrically connected to a controller inside the control panel 1. The solenoid valves 3 are connected in parallel with two hydraulic cylinders 4. The sensors 2 are mounted on the steering box 5 of the cutting machine. The solenoid valves 3 are mounted on one side of the upper part of the support frame 32 of the cutting machine and connected in series with the oil tank 33 of the cutting machine via an oil pump. A pressure gauge and a flow meter are installed on the pipes above the oil tank 33. The rear two sides of the support frame 32 are rotatably connected to the chassis 6 at its bottom, specifically via pins. The middle two sides are connected to the chassis 6 via two hydraulic cylinders 4, which are symmetrically arranged. The sensors 2 are used to detect the tilt angle of the steering box 5 and transmit the detected signal to the controller. In this embodiment, the sensors 2 are horizontal sensors. The controller issues commands to the solenoid valves 3 based on the signals detected by the sensors 2 or received from the control panel 1, controlling the extension and retraction of the hydraulic cylinders 4 to rotate the support frame 32, ensuring that the steering box 5 and the saw blade on the cutting shaft 7 of the cutting machine remain horizontally balanced.

[0025] The control panel 1 has a power button 8, an automatic calibration button 9, a sensitivity increase button 10, a sensitivity decrease button 11, an automatic button 12, a left increase and right decrease button 13, a left decrease and right increase button 14, and a display screen 15. Its operation includes automatic and manual modules. Before using the automatic module, adjust the two saw blades to be horizontal, press and hold the automatic calibration button 9 to perform calibration. Once the control panel 1 responds, calibration is complete. Then, press the automatic button 12 to enter the automatic module. In automatic mode, sensor 2 detects the tilt angle of the steering box 5 and transmits the signal to the controller. The controller sends a command to the solenoid valve 3 based on the received signal, automatically controlling the extension and retraction of the hydraulic cylinder 4. Since the rear end of the support frame 32 is rotatably connected to the chassis 6, and the middle part is connected to the chassis 6 via the hydraulic cylinder 4, the support frame 32 can rotate upwards or downwards around its rear end according to the extension and retraction of the hydraulic cylinder 4. This raises or lowers the support frame 32, the steering box 5 on the support frame 32, the transition shaft 17 connected to the steering box 5, the cutting shaft 7, and the two saw blades until sensor 2 detects that the steering box 5 is horizontal, completing the automatic leveling of the saw blades. In manual mode, the operator simply presses the left-raise / right-lower button 13 or the left-lower / right-raise button 14 according to the tilt of the saw blades to level the steering box 5 and the two saw blades.

[0026] In this embodiment, the cutting machine is a tracked cutting machine, and its chassis 6 is a tracked chassis 6. The upper part of the chassis 6 is rotatably connected to the support frame 32. The upper rear side of the support frame 32 is equipped with a motor 16 whose output shaft is forward-facing, and the upper front side is provided with a transition shaft 17 extending horizontally in the left-right direction. The transition shaft 17 is connected to the output shaft of the motor 16 through a steering box 5, specifically the steering box 5 is connected to the middle position of the transition shaft 17. The two ends of the transition shaft 17 are connected to the two ends of the cutting shaft 7 through a transmission belt 18. One end of the hydraulic cylinder 4 is connected to the chassis 6, and the other end is connected to the support frame 32 on both sides of the output shaft of the motor 16. Further, two symmetrical connecting rings 19 are coaxially provided on the transition shaft 17. The ends of the connecting rings 19 are connected to the cutting shaft 7 through a fixing frame 20, and the front end of the fixing frame 20 is connected to the saw blade baffle. After the motor 16 starts, its output shaft transmits rotation to the transition shaft 17 via the steering box 5, causing the transition shaft 17 to rotate. Simultaneously, the rotation is transmitted to the cutting shaft 7 via a belt, causing the saw blade (not shown in the figure) coaxially mounted on the cutting shaft 7 to rotate, cutting the road surface and completing the cutting operation. A hydraulic cylinder is also installed between the cutting shaft 7 and the chassis 6, which drives the saw blade to rise or fall synchronously during the cutting operation.

[0027] In addition, a control box 21 is also provided on the chassis 6. The upper part of the control box 21 is equipped with a display screen 22 for displaying the cutting rate and a voltmeter 23 for displaying voltage values; the middle part is equipped with a power indicator light 24 and a speed regulator 25; the lower part is equipped with an emergency stop button 26, a remote control trigger 27, a front-to-back adjuster 28, a left-to-right adjuster 29, an up-and-down adjuster 30, and a split-and-close adjuster 31. The buttons on the control box 21 are used to control the forward and backward movement, left and right turning, start and stop of operation, and up and down cutting.
