On facilitate the position of operation.
The course of work of one embodiment of 1~5 pair of sweeping machine of the present invention is illustrated with reference to the accompanying drawing:
1, the problem of movements such as when the first control system breaks down, tumble can not being executed:
The dynamical system of sweeping machine provides power by assistant engine or the direct-connected hydraulic pump 2 of chassis power taking 17, when the first control
When breaking down or install the control cabinet internal wiring of the first controller 14 inside device 14 and breaking down, it is likely to result in rubbish
Case 12 can not tumble, and maintenance difficulty greatly increases maintenance personal in this case and safety not can guarantee yet.
To solve the above-mentioned problems, it increases the second control system and carries out Redundant Control, pass through the control with chassis power taking 17
Route electrical connection processed, providing control power supply for the second control system, (power supply with the first controller 14 is not same electricity
Source), by the emergency button 15 being mounted on secondary operating case, the coil for controlling relay obtains electric, makes the control of the second control system
Line conduction, while using the one-way conduction characteristic of diode, the movement of first switch valve is controlled, hydraulic system is moved
Power, while change-over switch is connected to power taking interface, so that control dustbin 12 is tumbled, return and back door 9 are opened the door or shutdown acts
Operation button be electrically connected with corresponding solenoid valve, without the first controller 14, improvement in this manner, it can be ensured that
The key operations such as enabling, the shutdown of the tumbling of dustbin 12, return and back door 9 remain to perform effectively, and solve the first control system
System breaks down and causes cabinet that can not tumble, and the problems such as maintenance difficult.
2, the problem of disengagement speed being influenced for clutch air pressure deficiency and causing clutch damage:
In this embodiment, sweeping machine is equipped with blower and assistant engine, and clutch 18 starts for connecting blower with pair
Machine, gas bag provide power for the movement of clutch, are mounted on second controller inside control cabinet and are mounted on clutch 18
The pressure-detecting device 20 of air valve inlet end is electrically connected, and pressure-detecting device 20 is used to detect the atmospheric pressure value of gas bag side inlet end,
Second controller can receive the signal of pressure-detecting device 20 in control gas circuit, and second controller detects that the air pressure signal is greater than
Just allow to start when certain value (such as 0.6MPa), control air valve obtains electric, shoots out clutch cylinder, holdback clutch
18, and do not start when air pressure signal is less than the definite value, clutch cylinder is failure to actuate, and is solved clutch 18 and is taken off because of air pressure deficiency
The phenomenon that it is excessively slow to open speed, is in half-clutch state for a long time, causes clutch damage, improves the reliability of sweeping machine.
3, the problem of restarting influences electrical machinery life is occurred for assistant engine:
In this embodiment, assistant engine starts switch on the master control box being arranged in inside 1 driver's cabin 16 of chassis, when
After assistant engine starting operation, third controller is communicated by CAN bus and is electrically connected with the ECU controller on assistant engine, real
When data transmit, receive the tach signal of speed detector, revolving speed be higher than certain value (such as 500rpm) when, third control
The phenomenon that device, which can be realized, to be forbidden being again started up, and effectively avoids being fixed on the starting motor restarting on assistant engine, raising is opened
The service life of dynamic motor.
4, refuse cleaner is easy the problem of colliding with ground and barrier when for reversing:
In this embodiment, refuse cleaner includes sweeping disk 4 and sucker 5, in cleaning work, sweeps disk 4 and sucker 5 is tight
Ground is pasted, to reach optimal cleaning effect, when driver moves backward, the 4th controller and is fixed on 1 tail portion of chassis
The connection line of taillight 7 is electrically connected, and receives astern signal, and after astern signal triggering, disk oil cylinder 3 is swept in the automatic control of the 4th controller
It is driven respectively with sucker oil cylinder 6 and sweeps disk 4 and the rising of sucker 5, increased the road clearance, avoid colliding, after astern signal disconnects
Automatic to execute current action, intelligence significantly improves with reliability.
5, the problem of be easy to causeing water pump to be emptied when too low for cistern water level:
Water tank 11 is fixed by flange, is electrically connected with liquid level detection device 10 and the 5th controller, is in low in water tank 11
When position (such as at the 50mm of ground), the 5th controller disconnects the water pump 19 to work immediately, can effectively avoid water pump 19
It is emptied and damages for a long time, while the 5th controller is communicated by CAN bus, low level signal is sent to voice and is played
Device 13 informs operator (such as: filtered water tank water level is low, not can be carried out washing and cleaning operation) by speech form, improves reliability.
Pass through the explanation of multiple embodiments to sweeping machine of the present invention, it can be seen that sweeping machine embodiment of the present invention at least has
There is one or more of advantage:
1, by the second control system of setting, tumbling etc. for dustbin can be made dynamic when the first control system breaks down
It remains to perform effectively, solves the problems, such as to cause sweeping machine that can not work on because of maintenance difficult；
2, by setting pressure-detecting device and second controller, it is possible to prevente effectively from when starting assistant engine because of clutch
Device air pressure is insufficient and disengages the phenomenon that speed causes clutch damage slowly excessively, improves reliability；
