Description

Technical Field

[0001] This invention relates to the field of excavator handle operating systems, and more specifically to a multi-functional handle operating system and control method for excavators. Background Technology

[0002] The conventional excavator operating system is distributed across various handles and foot pedals. The excavator's forward and backward movement, as well as the operation of the robotic arm, are controlled by the left and right handles on either side of the seat and the various handles and foot pedals on the operating platform. Specifically, the left and right handles control the hydraulic system via oil pipes to control the robotic arm, while the foot pedals control the excavator's forward and backward movement. The operating platform handles control functions such as breaking, quick-change, yaw quick-change, hydraulic shear opening and closing, and rotation. However, this setup results in an excessive number of handles on the operating platform, leading to interference between them, inconvenient operation, and requiring a significant amount of space.

[0003] Therefore, this design proposes a convenient and streamlined operating system and control method for excavators using a multi-functional handle. The pilot control of multiple attachment pipelines is integrated into two multi-functional handles on the left and right sides, thereby reducing the number of handles on the operating platform, improving efficiency and simplifying operation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-functional handle operating system for excavators that is easy to operate and has a simplified operating space. By using multiple enable keys on the left handle in conjunction with multiple function keys on the right handle, different electrical signals are input to the controller. After processing, the controller outputs different signals to different solenoid valves. Different solenoid valves control different main valve pilot oil circuits, thereby realizing the control operation of multiple attachment pipelines such as the opening and closing of quick-change device, excavator swaying, hydraulic shear opening and closing, and rotation.

[0005] To solve the above-mentioned technical problems, the present invention provides a multi-functional handle operating system for excavators, characterized by including a controller RC4-5-30, a left handle, and a right handle; the left handle is provided with multiple enable keys and a left dial, and the right handle is provided with multiple function keys and a right dial, wherein the multiple enable keys and the left dial on the left handle are electrically connected to the signal input terminal of the controller, and the multiple function keys and the right dial on the right handle are electrically connected to the signal input terminal of the controller, and the signal output terminal of the controller is connected to multiple attachment pipelines.

[0006] With the above structure, multiple enable buttons on the left handle, in conjunction with multiple function buttons on the right handle, input different electrical signals to the controller, thereby combining and outputting different signals to different attachment pipelines to control the excavator to complete various actions, effectively improving efficiency and simplifying operation.

[0007] The controller model is RC4-5-30, named Rexroth BODAS controller. The controller's signal input terminal receives electrical signals transmitted from the handle. After processing and combining the electrical signals, the controller outputs different signal commands to the solenoid valve or proportional valve from the output terminal.

[0008] Preferably, the signal output terminals of the controller are respectively connected to the quick-change device via a quick-change solenoid valve, to the rotary motor via a first proportional valve, to the breaker via a second proportional valve, to the hydraulic shear via a third proportional valve, and to the hydraulic shear via a fourth proportional valve.

[0009] Preferably, the multiple enable buttons on the left handle include a first enable button, a second enable button, and a third enable button, and the multiple function buttons on the right handle include a first function button, a second function button, and a third function button. Different enable buttons and function buttons can input different electrical signals to the controller.

[0010] Preferably, both the left and right handles have operating areas at their upper ends. The first enable button, the second enable button, and the left dial are all located in the operating area of ​​the left handle, while the third enable button is located above the operating area of ​​the left handle. The first function button, the second function button, and the right dial are all located in the operating area of ​​the right handle, while the third function button is located above the operating area of ​​the right handle. The positions of the enable and function buttons are designed for ease of operation by the operator.

[0011] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator right yaw: First press the first enable button on the left handle, then press the first function button on the right handle. The controller signal input terminal receives the signals from the first enable button and the first function button in sequence. After processing by the controller, the right yaw signal is transmitted from the signal output terminal to the first proportional valve. The first proportional valve controls the slewing motor to rotate forward through the slewing oil circuit, thereby causing the excavator to yaw to the right.

[0012] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator left yaw: First press the first enable button on the left handle, then press the second function button on the right handle. After the controller signal input terminal receives the signals transmitted from the first enable button and the second function button in sequence, the controller processes the signals and transmits the left yaw signal from the signal output terminal to the first solenoid valve. The first proportional solenoid valve controls the slewing motor to reverse through the slewing oil circuit, thereby causing the excavator to yaw to the left.

[0013] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator working component switching: First, press and hold the second enable button on the left handle, then press and hold the first function button on the right handle. The controller signal input terminal receives the signals from the second enable button and the first function button in sequence. After processing by the controller, the signal output terminal transmits the signal to open the quick-change device to the quick-change solenoid valve. The quick-change solenoid valve controls the quick-change device to open through the quick-change oil pipe. Hydraulic shears or breakers can be installed on the quick-change device. When the second enable button and the first function button are released, the quick-change device closes, thus completing the switching and installation of the working components.

[0014] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator crushing: Switch the working part to the breaker hammer, and then press and hold the second function key on the right handle. After the controller signal input terminal receives the signal transmitted from the second function key, it processes the signal and transmits the crushing signal from the signal output terminal to the second proportional valve. The second proportional valve controls the breaker hammer through the breaker hammer oil circuit, thereby enabling the breaker hammer to perform crushing work.

[0015] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator hydraulic shear opening and closing: When the working part is switched to hydraulic shear, when the right impeller is turned to the right, the controller signal input terminal receives the signal transmitted from the right impeller in sequence. After processing by the controller, the signal output terminal transmits the hydraulic shear opening signal to the third proportional solenoid valve. The third proportional solenoid valve controls the hydraulic shear to open through the hydraulic shear opening and closing oil circuit. When the right impeller is turned to the left, the controller signal input terminal receives the signal transmitted from the right impeller in sequence. After processing by the controller, the signal output terminal transmits the hydraulic shear closing signal to the third proportional solenoid valve. The third proportional solenoid valve controls the hydraulic shear to close through the hydraulic shear opening and closing oil circuit, and the opening and closing speed increases with the increase of the turning amplitude.

[0016] The control method based on the multi-functional joystick operating system for excavators is characterized by the following steps: Excavator Hydraulic Shear Rotation: When the working component is switched to hydraulic shear, turning the left impeller to the right sequentially receives signals from the left impeller. After processing, the controller outputs a clockwise rotation signal for the hydraulic shear to the fourth proportional solenoid valve. The fourth proportional solenoid valve controls the hydraulic shear to rotate clockwise via the hydraulic shear rotation oil circuit. Conversely, turning the left impeller to the left sequentially receives signals from the left impeller. After processing, the controller outputs a counter-clockwise rotation signal for the hydraulic shear to the fourth proportional solenoid valve. The fourth proportional solenoid valve controls the hydraulic shear to rotate counter-clockwise via the counter-clockwise rotation oil circuit, and the opening and closing speed increases with the amplitude of the movement.

[0017] In summary, the beneficial effects of this invention are as follows: by integrating the pilot control of multiple sets of attachment pipelines onto two multi-functional handles on the left and right sides, the operating space is simplified. Different electrical signals are input to the controller through the left and right handles, and the controller processes and combines these signals to output different attachment pipelines, thereby controlling the excavator to complete various actions, effectively improving efficiency and simplifying operation.
