Definitions
- the invention relates to a drive device for pivoting adjustment Brush arm of a tunnel washing vehicle, with a hydraulically operated one Cylinder-piston unit.
- Such Unit enables rapid adjustment and, in particular, rapid shortening, when there is an obstacle to avoid.
- the disadvantage is that Sealing problems arise and that when avoiding an obstacle is that the pressure inside the cylinder has to be greatly reduced, whereby for the restoration of the full contact pressure of the boom, that is the target extended position, large amounts of compressed air are replenished have to.
- the possible extension length is advantageous to a large extent from the hydraulic actuated cylinder-piston unit determined, this unit in the Extend position is stable and does not tend to shrink longitudinally.
- the pneumatically actuated cylinder-piston unit practically also forms an air spring, which over the brush minor bumps or compensate for obstacles without changing the pressure can.
- each of the two Cylinder-piston units consist of cylinder, piston and piston rod, which two cylinders connected to each other and the supports on the vehicle or boom rods attacking the boom are guided out on opposite sides are.
- Simply built cylinder-piston units can be used here find that on the cylinders only via a simple coupling piece need to be connected.
- the operation of the drive device is simplified and the adjustment accuracy of the brush boom, if according to the invention for the pneumatic actuatable cylinder-piston unit one or more position sensors are provided, which act on the hydraulically actuated via a control device Regulate the cylinder-piston unit in the sense of a tracking control.
- the desired contact pressure of the brush boom brushes is determined here Regulation of the pressurization of the pneumatically operated cylinder-piston unit given. Because of the tracking control, the hydraulically operated follows Cylinder-piston unit automatically in its setting, so that on this Way & a. Changes in distance of the tunnel washing vehicle from the tunnel wall automatically by changing the length of the hydraulically operated cylinder-piston unit be balanced. The operator only has that Task to observe the correct position of the brush arm and in the event of obstacles in time by operating the control for the pneumatically operated Cylinder-piston unit to bring about the evasive movement. Here can be provided in the control device delay elements to prevent that in a short-term evasion then an unnecessary per se The hydraulically operated cylinder-piston unit is adjusted.
- a tunnel washing vehicle was essentially only the one on the chassis and the wheels 1 supported tank 2 for the washing liquid.
- two brush arms 3, 4 are attached.
- the rotatably drivable and at one end adjustable washing brushes 5 carries and with its other end to one not shown transverse axis can be pivoted up and down and about a vertical axis 6 is pivotable to the side.
- a drive device according to the invention engages on the boom 3 7, which serves the pivoting about the vertical axis 6, immediately on, whereas a drive device 7 for the second boom 4 over a lever 8 is connected to this boom 4.
- the drive device consists of a hydraulically operated cylinder-piston unit 9 and a pneumatic one actuatable cylinder-piston unit 10.
- the cylinders 11, 12 of the cylinder-piston units 9, 10 are connected via an adapter plate 13 and the piston rods 14, 15 of the two cylinder-piston units 9, 10 are opposite Pages led out and on a support 16 and 17 on the vehicle and on Boom 3 or articulated on the lever 8 of the boom 4.
- the pressurization lines 18, 19 for the cylinder 11 the hydraulically actuated cylinder-piston unit 9 lead to a piston spool 20 indicated hydraulic regulator, the two inputs for connection has a feed pump 21 and a return line 22 in the illustrated Middle position the line 18, 19 blocks and thus the hydraulically operated Cylinder-piston unit 9 fixed in the current extended position, as well as in the two working positions, the lines 18, 19 alternately with the pump 21 and Return 22 connects.
- Working magnets 23, 24 determine when they are switched on the two working positions. For the actuation of these working magnets 23, 24 a central control unit 25 is provided, which is connected to sensors 26, 27 is.
- the control unit 25 switches the working magnet 23 a so that this connects the pump 21 to the line 18 and the piston 14 of the cylinder-piston unit 9 is urged in the direction of extension. Reached the piston of the cylinder-piston unit 7 the sensor 27, then switches Control unit 25, the working magnet 24, so that the control slide 20 Pump 21 connects to line 19 and line 18 to the return 22 so that the piston 14 of the cylinder-piston unit 9 moves back into the cylinder 11.
- the duration of exposure to the hydraulic cylinder-piston unit 9 can be regulated by a timer. Another option is on the pneumatically actuated cylinder-piston unit 10 a z.
