Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
A kind of compression vehicle push pedal and rear tail anticollision device, collision-prevention device, including side brush connecting rod 1, side brush folding and unfolding oil cylinder 2, side brush connecting rod 1
One end is hinged with the rocker arm shaft 3 being fixed on vehicle body, and its other end is provided with side brush assembly 4, as it is shown in figure 1, described
One end of side brush folding and unfolding oil cylinder 2 is hinged on vehicle body, and one end of the piston rod stretching out cylinder body on its other end is hinged on side
The position of deflection side brush assembly 4 one end, middle part of brush connecting rod 1, the pressure chamber of side brush folding and unfolding oil cylinder 2 connects pressure switch YK,
This pressure switch YK is connected with control circuit (as shown in Figure 4), and this control circuit is connected with a solenoid directional control valve 5, electromagnetic switch
The input of valve 5 is connected with the output of fuel feeding hydraulic pump 6 by oil pipe, and two tunnel outputs of solenoid directional control valve 5 are by oil pipe respectively
Oil-feed, oil back chamber with side brush folding and unfolding oil cylinder 2 are connected, and concrete hydraulic circuit can refer to Fig. 3 and realized；At side brush assembly 4
On crashproof guard ring that is rigidly connected with side brush connecting rod 1 and that protrude from side brush assembly 4 or block 7 are installed, such as Fig. 2, if side brush is total
The intensity become is enough, and this crashproof guard ring or block 7 also can save.
Dodge motion to realize being combined, the side brush folding and unfolding oil cylinder 2 pin joint with vehicle body when being embodied as, should be made higher than side
Brush connecting rod 1 and the pin joint of rocker arm shaft 3.
The side brush organization hydraulic pressure CAS working procedure of the present invention:
Compression vehicle cleaning work, side brush folding and unfolding oil cylinder 2 stretches out and puts down side brush, and side brush contact road surface, compression vehicle is along before road
Entering and clean road surface, when side brush is encountered barrier or runs into bigger resistance, circuit connected by pressure switch, and side brush folding and unfolding oil cylinder 2 is received
Returning avoiding obstacles, when hydraulic cylinder piston moves to stroke end of a period, pressure switch disconnecting circuit, side brush folding and unfolding oil cylinder 2 is stretched
Go out and put down side brush, continue cleaning work.
System design parameters:
Maximum puts down pressure P1:20Bar；
Maximum news send out pressure P2:25Bar；
Speed reference/m.s-1: put down speed V1:0.1, withdrawal speed: 0.15.
The hydraulic pressure of the present invention and electrical system operation principle:
Fig. 3 show compression vehicle side brush anticollision mechanism hydraulic system principle figure, and Fig. 4 is side brush anticollision mechanism circuit theory
Figure.Fuel feeding hydraulic pump 6 is driven by electromotor and is used for feed system hydraulic oil, and its pressure is set up by electromagnetic relief valve 12.
Semi-self-resetting bit switch SW1 connects, the coil D1 energising of solenoid directional control valve 5, electromagnetic relief valve coil D3 energising simultaneously
Overflow, the rodless cavity of fluid input side brush folding and unfolding oil cylinder 2, piston rod stretches out, and puts down side brush, and compression vehicle advances.Side brush puts down speed
Degree is set up by one-way throttle valve 11, puts down pressure P1 and is set up by air relief valve 8, and sender pressure P2 is set up by pressure switch YK, P2
Slightly larger than P1.If side brush is encountered barrier or runs into bigger resistance, the rodless cavity pressure of side brush folding and unfolding oil cylinder 2 then rapidly rises to
Pressure switch YK sender pressure P2, now relay J Z1 connects the coil D2 of solenoid directional control valve 5, fluid input side brush folding and unfolding oil
The rod chamber of cylinder 2, piston rod retraction, side brush is packed up.Side brush is packed up speed and is set up by one-way throttle valve 10, owing to using oil return to adjust
Speed, the back pressure in oil back chamber is more than pressure switch YK sender pressure P2, and piston is in continuous kinestate.When piston is to moving to
When stroke is ended, the rodless cavity rapid pressure drop of side brush folding and unfolding oil cylinder 2 is less than pressure switch YK sender pressure P2, pressure relay
Device disconnecting circuit makes relay J Z1 connect electromagnetic switch valve coil D1, the rodless cavity of fluid input side brush folding and unfolding oil cylinder 2, piston
Bar stretches out, and puts down side brush.When side brush quits work, connect semi-self-resetting bit switch SW2, the coil D2 energising of solenoid directional control valve 5,
The rod chamber of fluid input side brush oil cylinder 9, piston rod retraction, side brush is packed up, and unclamps semi-self-resetting bit switch disconnecting circuit, and electromagnetism changes
Being in middle position, electromagnetic relief valve 12 power-off drain charge to valve 5, hydraulic control one-way valve 9 controls the rod chamber of side brush folding and unfolding oil cylinder 2, has made
Bar chamber liquid bears side brush gravity load, it is to avoid side brush declines.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, and this technology is led
Change that the technical staff in territory is made in the essential scope of the present invention, retrofit, add or replace, also should belong to the present invention's
Protection domain.
