DETAILED DESCRIPTION

[0020] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. The embodiments of the present invention and the technical features in the embodiments may be combined with each other unless there is a conflict.

For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0022] Example 1 This embodiment introduces a noise optimization control system for an actuator of a sanitation vehicle, which includes: a hydraulic control circuit, a pneumatic control circuit and a controller; The hydraulic control circuit comprises: a hydraulic oil tank 1, a main reversing valve 2, an actuating oil cylinder 3 and an oil pump 4; the first working port A and the second working port B of the main reversing valve 2 are respectively connected with the rodless chamber oil port and the rod chamber oil port of the actuating oil cylinder 3, the oil inlet P of the main reversing valve 2 is connected with the oil outlet of the oil pump 4; the oil return port T of the main reversing valve 2 is connected with the hydraulic oil tank 1; The pneumatic control circuit includes: an air source 5, a first reversing valve 6, a second reversing valve 7, a reversing cylinder 8 and a first buffer assembly; the air source 5 is connected to the rodless cavity air port and the rod cavity air port of the reversing cylinder 8 through the first air path 9 and the second air path 10 respectively; the first reversing valve 6 and the second reversing valve 7 are respectively arranged on the first air path 9 and the second air path 10; the controller is electrically connected to the control ends of the first reversing valve 6 and the second reversing valve 7 respectively; In the working state, the reversing cylinder 8 controls the main reversing valve 2 to switch the working port by extending or retracting the reversing cylinder 8, thereby controlling the extension or retraction of the acting cylinder 8; wherein, the first buffer assembly is arranged on the reversing cylinder 8, and is used to reduce the speed at which the reversing cylinder 8 pushes the valve stem in the main reversing valve 2 to switch the working port.

[0023] It is worth noting that the above-mentioned reversing cylinder 8 and the main reversing valve 2 are integrally arranged, that is, the piston rod of the reversing cylinder 8 is connected to the valve stem in the main reversing valve 2, so that the reversing cylinder 8 can push the inner valve stem in the main reversing valve 2 to switch the working port.

[0024] In the actual application of this embodiment, when the actuator (i.e., the action cylinder 3) needs to be extended, the controller receives an extension control instruction from a human-machine interaction unit (such as a button, a touch screen, etc.). Then, the controller controls the first reversing valve 6 to switch to the working position according to the instruction, so that the compressed air enters the rodless chamber of the reversing cylinder 8 from the air source 5 through the first air path 9 (after the damping adjustment of the first air path damping), and at the same time, the air in the rod chamber of the reversing cylinder 8 is discharged to the atmosphere through the second air path 10 (after the damping adjustment of the second air path damping). Then, the reversing cylinder 8 extends due to the increase in the air pressure in the rodless chamber, and its extended end pushes the inner valve stem of the main reversing valve 2 to move, so that the working port of the main reversing valve 2 is switched to the first working port A. Finally, the hydraulic oil provided by the oil pump 4 enters the rodless chamber of the action cylinder 3 through the oil inlet P of the main reversing valve 2, pushing the cylinder to extend.

[0025] When the actuator needs to be retracted, the controller receives the retraction control instruction from the human-machine interaction unit. Then, the controller controls the second reversing valve 7 to switch to the working position according to the corresponding instruction, so that the compressed air enters the rod chamber of the reversing cylinder 8 from the air source 5 through the second air path 10 (after the second air path damping adjustment of the first buffer component), and at the same time, the air in the rodless chamber of the reversing cylinder 8 is discharged to the atmosphere through the first air path 9 (after the damping adjustment of the first air path damping). Then, the reversing cylinder 8 is retracted due to the increase in the air pressure in the rod chamber, which pushes the inner valve stem of the main reversing valve 2 to move, so that the working port of the main reversing valve 2 is switched to the second working port B. Finally, the hydraulic oil provided by the oil pump 4 enters the rod chamber of the actuating cylinder 3 through the oil inlet P of the main reversing valve 2, pushing the cylinder to retract. At the same time, the hydraulic oil in the rodless chamber of the actuating cylinder 3 flows back to the hydraulic oil tank 1 through the oil return port T of the main reversing valve 2.

[0026] Example 2 refer to Figure 1 Based on Example 1, this example also has the following design.

[0027] The noise optimization control system for the sanitation vehicle actuator includes a first buffer component and a second buffer component.

[0028] The first buffer assembly includes a first air path damper 11 and a second air path damper 12. The first air path damper 11 is installed at the rodless cavity air port of the reversing cylinder 8, and the second air path damper 12 is installed at the rod cavity air port of the reversing cylinder 8.

[0029] Specifically, when the reversing cylinder 8 needs to be extended (i.e., the rodless chamber is inflated), the first air path damper 11 will limit the rapid flow of the airflow, making the extension of the reversing cylinder 8 smoother and slower. At the same time, the second air path damper 12 will also limit the airflow in the rod chamber of the reversing cylinder 8 to be slowly discharged to the atmosphere. When the reversing cylinder 8 needs to be retracted (i.e., the rod chamber is inflated), the second air path damper 12 will also limit the rapid flow of the airflow, ensuring that the retraction action is also smooth and slow. At the same time, the first air path damper 11 will also limit the airflow in the rodless chamber of the reversing cylinder 8 to be slowly discharged to the atmosphere.

[0030] The second buffer assembly includes a third gas path damper 13 and a fourth gas path damper 14. The third gas path damper 13 is installed at the first exhaust port corresponding to the first reversing valve 6, and the fourth gas path damper 14 is installed at the second exhaust port corresponding to the second reversing valve 7.

[0031] In actual application, the first buffer component and the second buffer component are used in combination to effectively reduce the impact noise of the sanitation vehicle actuator during operation, as described below: Actuator extension process: The controller controls the first reversing valve 6 to switch to the working position (i.e., the electromagnet YV1 of the first reversing valve 6 is energized) according to the actuator extension control instruction output by the human-machine interaction unit, so as to allow the compressed air to enter the rodless chamber of the reversing cylinder 8 through the first gas path damper 11 from the working position of the first reversing valve 6. At the same time, the air in the rod chamber of the reversing cylinder 8 is discharged to the atmosphere through the second gas path damper 12 and the fourth gas path damper 14. Then, the reversing cylinder 8, driven by the gas, moves the inner valve stem of the main reversing valve 2 until it switches to the first working port A, and the action cylinder 3 completes the extension, i.e., the corresponding actuator completes the extension action.

[0032] Actuator retraction process: The controller controls the second reversing valve 7 to switch to the working position (i.e., the electromagnet YV2 of the second reversing valve 7 is energized) according to the actuator retraction control instruction output by the human-machine interaction unit, so as to allow the compressed air to enter the rod chamber of the reversing cylinder 8 through the second gas path damper 12 from the working position of the second reversing valve 7. At the same time, the air in the rodless chamber of the reversing cylinder 8 is discharged to the atmosphere through the first gas path damper 11 and the third gas path damper 13. Then, the reversing cylinder 8 moves the inner valve stem of the main reversing valve 2 under the push of the gas until it switches to the second working port B, and the action cylinder 3 completes the retraction, i.e., the corresponding actuator completes the retraction action.

[0033] Among them, the first reversing valve 6 and the second reversing valve 7 in this embodiment are two-position two-way solenoid valves. The first reversing valve 6 and the second reversing valve 7 can be integrated into the electrical control multi-way valve, or they can exist independently. Secondly, the first reversing valve 6 and the second reversing valve 7 can be components, or they can exist independently according to the layout requirements.

[0034] This embodiment uses the combined action of the first buffer component and the second buffer component to significantly reduce the noise generated during the action switching and air pressure change process, while reducing the impact and wear on the system. This not only improves the stability and reliability of the system, but also makes the sanitation vehicle quieter and more environmentally friendly when performing tasks.

[0035] In addition, the apertures of the first gas path damper 11 , the second gas path damper 12 , the third gas path damper 13 and the fourth gas path damper 14 can be adaptively determined according to the control requirements of the actuating cylinder 3 .

[0036] It is worth noting that the noise optimization control system for the actuator of the sanitation vehicle in this embodiment also includes a first proximity switch 15 and a second proximity switch 16. The control ends of the first proximity switch 15 and the second proximity switch 16 are electrically connected to the controller respectively, and are used to detect the position of the actuating cylinder 3 and output the corresponding position detection data to the controller. Among them, the position detection data includes: the extended position data detected by the first proximity switch 15 and the retracted position data detected by the second proximity switch 16. In addition, the controller also controls the first reversing valve 6 or the second reversing valve 7 to switch from the working position to the normal position according to the position detection data.

[0037] In actual application, when the actuator needs to extend, the controller controls the electromagnet YV1 of the first reversing valve 6 to be energized, so that the compressed air enters the rodless chamber of the reversing cylinder 8, pushes the reversing cylinder to extend, and drives the main reversing valve 2 to switch the working port, thereby driving the action cylinder 3 to extend. When the action cylinder 3 is extended to the position, the first proximity switch detects the extension data and sends the data to the controller. Based on the received extension data, the controller controls the electromagnet YV1 of the first reversing valve 6 to lose power, so that the first reversing valve switches back to the normal position. At this time, the compressed air will be discharged to the atmosphere through the first gas path damper 11 (slowing down the exhaust speed and reducing noise) and the third gas path damper 13 (further controlling the exhaust flow).

[0038] Correspondingly, when the actuator needs to be retracted, the controller controls the electromagnet YV2 of the second reversing valve 7 to be energized, so that the compressed air enters the rod chamber of the reversing cylinder 8, pushes the reversing cylinder to retract and drives the main reversing valve 2 to switch the working port, and then drives the action cylinder 3 to retract. When the action cylinder 3 is retracted into place, the second proximity switch detects the retraction data and sends the data to the controller. Based on the received retraction data, the controller controls the electromagnet YV2 of the second reversing valve 7 to lose power, so that the second reversing valve switches back to the normal position. At this time, the compressed air is discharged to the atmosphere through the second gas path damper 12 (slowing down the exhaust speed and reducing noise) and the fourth gas path damper 14 (further controlling the exhaust flow).

[0039] In summary, in this embodiment, through the precise detection of the proximity switch, the controller can accurately know the position state of the actuating cylinder 3, thereby realizing precise control of the reversing valve. At the same time, the air path damping in the first buffer assembly and the second buffer assembly effectively slows down the flow speed of the compressed air, and reduces the noise generated by the system during the action switching and air pressure change process. In addition, the introduction of the proximity switch not only improves the control accuracy of the system, but also increases the safety of the system. For example, when the actuating cylinder 3 does not reach the specified position, the controller will not mistakenly switch the reversing valve, avoiding possible system damage or safety accidents.
