Description
Technical Field
The invention relates to the field of sanitation equipment, in particular to a method and a system for controlling the pressure stabilization of a pneumatic clutch of a sanitation vehicle.
Background
The existing sanitation road sanitation vehicles such as sweeping machines, washing and sweeping vehicles, dust suction vehicles, cleaning vehicles and other special operation vehicles are generally provided with fan or high-pressure water pump operation devices, and some or even two operation devices coexist. The fan and the water pump device are controlled by a pneumatic clutch in the operating state.
Generally, the power of the fan is relatively high and is controlled by a friction plate type pneumatic clutch, and the power of the water pump is relatively low and is controlled by a tooth type pneumatic clutch. No matter which clutch is adopted, the friction component is pushed by air pressure to transmit power, and the clutch is released by a return spring.
The pneumatic clutches have the optimal working air pressure value, the normal air pressure of the clutch used on the sanitation road sanitation vehicle operation device is between 0.4 and 0.6MPa, an air source is often from a running chassis, and the air pressure of the chassis is unstable (the air pressure of the chassis air source is low in a starting stage and fluctuates due to long-time parking and the like).
If the air pressure is too large: the tooth clutch has the defects that the axial force of the middle transition shaft sleeve is too large, the middle structure is easily damaged, and the service life of a sealing ring can be influenced. The friction plate type clutch has the advantages that the middle transition separates the bearing from the overlarge axial force, the bearing pressure ratio is large, the bearing structure is easy to damage, the service life of a sealing ring can be influenced, and the spring of the friction plate is easy to overload or lose efficacy due to the fact that the spring of the friction plate is under the high-pressure axial force for a long time.
If the air pressure is too small: the gear-type clutch has gear-beating phenomenon, which seriously damages the clutch structure. The friction plate type clutch is not combined in place, so that the friction slip phenomenon occurs and the friction plate is damaged. Thus, the later maintenance cost is increased, and certain potential safety hazards exist.

Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 3, the sanitation vehicle pneumatic clutch pressure stabilizing system of the present embodiment includes an air source, an air valve, a pneumatic clutch and a pressure stabilizing device, wherein the sanitation vehicle air source, the air valve and the pneumatic clutch are sequentially connected by a pipeline, and the sanitation vehicle pressure stabilizing device is used for determining that the air source pressure is within a predetermined range. And when the pressure stabilizing device judges that the pressure of the air source is within the preset range, the air valve is opened, otherwise, the air valve is closed, and stable air pressure suitable for the working of the pneumatic clutch is output to the pneumatic clutch so that the pneumatic clutch works stably. The pneumatic clutch has the advantages that the pneumatic clutch is prevented from transmitting air pressure to the pneumatic clutch when the air source pressure is too low or too high, so that the damage to parts of the pneumatic clutch caused by too low or too high air source pressure is avoided, the later maintenance cost is effectively reduced, and the safety is improved. Further, the pressure stabilizing device is a sensor, the sensor is installed on the air source, the sensor is used for detecting the pressure of the air source, whether the pressure of the air source is within a preset range or not is judged according to the pressure value detected by the sensor, and if the pressure of the air source is within the preset range, the air valve is opened, and if the pressure of the air source is not within the preset range, the air valve is not closed. Further, the pressure stabilizing device further comprises a controller, the controller is in communication connection with the sensor, and the controller is electrically connected with the air valve, so that automatic opening and closing control of the air valve is realized, and the automation level is improved. Furthermore, the pneumatic clutch further comprises a pressure reducing valve, wherein the pressure reducing valve is connected between the air valve and the pneumatic clutch to further stabilize the output pressure and ensure that the working pressure of the pneumatic clutch is stable.
As shown in fig. 1, when the sanitation vehicle is in operation or the brakes are applied for a long time, the chassis air supply pressure may be unstable (the air pressure may fluctuate in the range of 0-9 MPA). The sensor detects the pressure of the air source, after the sensor detects the air pressure, the sensor transmits a pressure signal to the controller, the controller judges whether to open the air valve according to the pressure signal so as to judge whether the air source pressure can reach the working air pressure of the pneumatic clutch, when the air source pressure exceeds the set air pressure value of the controller (the set air pressure value of the controller is in the range of 0.5MAP-0.8MPA, the set air pressure value of the controller is greater than the working pressure of the pressure reducing valve, namely greater than the working pressure of the pneumatic clutch, in the embodiment, the set air pressure value is 0.6MPA), the controller opens the air valve, at the moment, the unstable air pressure which is higher than the working air pressure of the pneumatic clutch enters the pressure reducing valve and is reduced to 0.5MPA through the pressure reducing valve (the working pressure range of the pressure reducing valve is 0.4MPA-0.6MPA, the working pressure of the pressure reducing valve is 0., and the output pressure of the pressure reducing valve is kept to be 0.5MPA, the specific working pressure of the pressure reducing valve is not limited to the working pressure of the embodiment, the working pressure of the pressure reducing valve is selected according to the working pressure required by the pneumatic clutch, and the working pressure of the pressure reducing valve is greater than the working pressure of the air valve), so that the stable air pressure suitable for the pneumatic clutch to work is output to the pneumatic clutch, and the pneumatic clutch works stably. The pneumatic clutch has the advantages that the pneumatic clutch is prevented from transmitting air pressure to the pneumatic clutch when the air source pressure is too low or too high, so that the damage to parts of the pneumatic clutch caused by too low or too high air source pressure is avoided, the later maintenance cost is effectively reduced, and the safety of a vehicle is improved. Further, when the sensor detects that the air pressure of the air source is smaller than the working pressure of the pressure reducing valve, the controller controls the air valve to be closed, so that the air valve is opened when the air pressure of the air source is higher than the working pressure of the pressure reducing valve, and when the air pressure of the air source fluctuates within a range larger than the working pressure of the pressure reducing valve, stable pressure can still be output under the action of the pressure reducing valve, and the working stability of the pneumatic clutch is improved.
Furthermore, the sanitation vehicle pneumatic clutch pressure stabilizing system also comprises a working component, the working component is connected with the pneumatic clutch, and the working component can be a fan or a water pump.
When the working part adopts a fan, the fan is controlled by a friction plate type pneumatic clutch because the power of the fan is high. When the friction plate pneumatic clutch works in a pressure stabilizing mode, the phenomenon that the working air pressure of the friction plate pneumatic clutch is too large, the phenomenon that the axial force of a middle transition separation bearing of the friction plate pneumatic clutch is too large and the bearing pressure ratio of the bearing is large, so that the bearing structure is damaged is avoided, and the phenomenon that the spring of the friction plate is easily overloaded or easily fails due to the fact that the spring of the friction plate is under the high-pressure axial force for a long time is avoided. Meanwhile, the friction plate type pneumatic clutch can avoid the friction slipping phenomenon and damage to the friction plate due to the fact that the friction plate type pneumatic clutch is not combined in place when the working air pressure of the friction plate type pneumatic clutch is too small. The stable work of the fan is ensured.
When the working component adopts a water pump, the power of the water pump is relatively small, and the gear type pneumatic clutch is generally adopted for control. When the gear type pneumatic clutch works in a pressure stabilizing mode, the damage to the middle structure caused by overlarge working air pressure of the gear type pneumatic clutch and overlarge axial force of the middle transition shaft sleeve of the gear type pneumatic clutch can be effectively avoided. Meanwhile, the phenomenon that the gear-type clutch is damaged due to the fact that the working air pressure of the friction plate type pneumatic clutch is too small is avoided. Ensure the stable operation of the water pump.
Furthermore, the pressure switch can be selected as the sensor, the pressure switch is adopted to directly output the switching value, the conversion of the analog quantity is not needed, the controller can be simplified, the singlechip is adopted for control, and the cost is saved. The lower limit action pressure setting range of the pressure switch is between 0.5MPA and 0.8 MPA. As shown in fig. 2, in this embodiment, the lower limit operation pressure value is set to be 0.6MPA, and when the air source pressure is greater than 0.6MPA, the pressure switch is triggered, the pressure switch sends a switch signal to the controller, and the controller controls the air valve to open. Meanwhile, the upper limit action pressure can be set, when the air valve fails and the air source pressure is too high, the upper limit action pressure of the pressure switch is exceeded, the pressure switch is triggered, the pressure switch sends a switch signal to the controller, and the controller controls the air source air pump to stop supplying air to protect the air source.
In other embodiments, the sanitation vehicle pneumatic clutch pressure stabilizing system further comprises a display, the display is in communication with the controller, and the display is used for displaying the air source pressure and the working state of the air valve. The pressure regulating valve is convenient to monitor the air source pressure and the working state of the air valve in real time, can regulate the working pressure of the air valve according to the state of the air source pressure, and is favorable for keeping the working stability of the pressure reducing valve. Further, the pressure stabilizing system of the pneumatic clutch of the sanitation vehicle further comprises an alarm, and when the air source pressure is too low, the air source pressure is too high, or the air source pressure fluctuation is abnormal, the alarm gives an alarm to prompt the abnormality so as to be convenient for timely inspection and repair.
In other embodiments, the road sweeping sanitation vehicle comprises a chassis and the sanitation vehicle pneumatic clutch pressure stabilizing system, wherein the air source is an air source of the chassis of the sanitation vehicle, and the pneumatic clutch is mounted on the chassis.
When the vehicle is in operation or the brake is used for a long time, the air pump of the chassis works continuously, so that the air pressure of the air source of the chassis is unstable. The controller opens the air valve when the air pressure exceeds a set air pressure value of the controller, the air valve is unstable and higher than the air pressure of the pneumatic clutch and enters the pressure reducing valve, the stable air pressure suitable for the working of the pneumatic clutch is output to the pneumatic clutch, and the fan and the water pump are driven to work stably. The pneumatic clutch has the advantages that the pneumatic clutch is prevented from transmitting air pressure to the pneumatic clutch when the air source pressure is too low or too high, so that the damage to parts of the pneumatic clutch caused by too low or too high air source pressure is avoided, the later maintenance cost is effectively reduced, and the safety of a vehicle is improved.
According to the above embodiments, the inventor provides a method for controlling the pressure stabilization of a pneumatic clutch of a sanitation vehicle, as shown in fig. 3, comprising the following steps; setting a first preset value of a chassis of the sanitation truck; detecting the pressure value of the chassis air pressure of the sanitation vehicle; comparing the first preset value with the pressure value of the chassis air pressure of the sanitation vehicle, and if the pressure value of the chassis air pressure of the sanitation vehicle is smaller than the first preset value, the controller does not open the air valve; if the pressure value of the chassis air pressure of the sanitation vehicle is larger than the first preset value, the controller opens the air valve. The method comprises the steps of detecting the pressure value of the chassis air pressure of the sanitation vehicle by setting a first preset value of the chassis of the sanitation vehicle, comparing the first preset value with the pressure value of the chassis air pressure of the sanitation vehicle, judging that the chassis air pressure of the sanitation vehicle is larger than the first preset value, indicating that the chassis air pressure of the sanitation vehicle is stable, opening an air valve by a controller, outputting stable air pressure suitable for the pneumatic clutch to work to the pneumatic clutch, enabling the pneumatic clutch to work stably, and closing the air valve by the controller if the pressure value of the chassis air pressure of the sanitation vehicle is smaller than the first preset value. The pneumatic clutch has the advantages that the pneumatic clutch is prevented from transmitting air pressure to the pneumatic clutch when the air source pressure is too low or too high, so that the damage to parts of the pneumatic clutch caused by too low or too high air source pressure is avoided, the later maintenance cost is effectively reduced, and the safety is improved.

Further stabilize output pressure, ensure that pneumatic clutch operating pressure is stable.

When the chassis air pressure for the sanitation vehicle does not reach the working pressure of the pneumatic clutch, an operator is prompted to wait, and misoperation is avoided. Furthermore, the first early warning value is larger than or equal to the second preset value, the controller does not close the air valve when the pressure value of the chassis air pressure of the sanitation vehicle is smaller than the first preset value, and the air valve is closed only when the pressure value of the chassis air pressure of the sanitation vehicle is smaller than the first early warning value. Namely, when the chassis air pressure of the sanitation vehicle is detected to be larger than a first preset value, the controller opens the air valve, and when the chassis air pressure of the sanitation vehicle is detected to be smaller than a first early warning value, the controller closes the air valve, so that when the chassis air pressure of the sanitation vehicle fluctuates within a range larger than a second preset value, stable pressure can still be output, and the working stability of the pneumatic clutch is improved.
Further, the method also comprises the following steps; setting a second early warning value of a chassis of the sanitation truck; and comparing the first early warning value with the pressure value of the chassis air pressure of the sanitation vehicle, when the pressure value of the chassis air pressure of the sanitation vehicle is greater than the second early warning value, prompting that the pressure value of the chassis air pressure of the sanitation vehicle is greater than the second early warning value, and closing the air valve by the controller to avoid the fault caused by overlarge pressure.

Namely, when the chassis air pressure of the sanitation vehicle is detected to be larger than a first preset value, the controller opens the air valve, and when the chassis air pressure of the sanitation vehicle is detected to be smaller than a first early warning value, the controller closes the air valve, so that when the chassis air pressure of the sanitation vehicle fluctuates within a range larger than a second preset value, stable pressure can still be output, and the working stability of the pneumatic clutch is improved.
Further, the method also comprises the following steps; setting a second early warning value of a chassis of the sanitation truck; and comparing the first early warning value with the pressure value of the chassis air pressure of the sanitation vehicle, when the pressure value of the chassis air pressure of the sanitation vehicle is greater than the second early warning value, prompting that the pressure value of the chassis air pressure of the sanitation vehicle is greater than the second early warning value, and closing the air valve by the controller to avoid the fault caused by overlarge pressure.
It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
