Definitions

  • the invention relates to a device for optionally blocking traffic areas.
  • German utility model DE-U-9404293.4 remove Such an embodiment can be found in German utility model DE-U-9404293.4 remove.
  • This device comprises a hollow cylinder A shaft pipe sunk directly into the ground, which is located at the bottom Completed end over a base and flush at its top end by one is closed with the bottom closing plate.
  • a stake carries on its lower end a guide piston which is slidably mounted in the hollow cylinder is.
  • a bellows is arranged, which has a closed surface, from below presses against the guide piston.
  • the base has an inlet into the inner chamber of the bellows. Suitable facilities are provided that allow the inner chamber of the bellows with a fluid, e.g. B. to apply compressed air.
  • the bellows is dimensioned so that it is in the expanded state Pile drives a desired dimension out of the hollow cylinder.
  • the on closure plate located on the surface of the earth has a central bore, in who is leading the stake. In its lower starting position, the pile becomes complete withdrawn into the hollow cylinder; the top face of the pile then just ends with the sealing plate and the surface of the earth. Will the before by applying z. B. vented with compressed air bellows, so the bellows resets itself radially; then the pile sinks under his Weight back to its lower starting position and thus presses the bellows to its compressed lower position.
  • the invention has for its object the structure and operation of the above improve described device.
  • the embodiment according to the invention therefore dispenses with one Bellows.
  • the shaft pipe also encloses the Compressed air to fill the pressure chamber, so that the entire device its structure is kept simple and robust.
  • a compressed air reservoir is connected to the piston is connected to a compressed air line for its filling is.
  • a vent pipe is arranged eccentrically on which the piston rod flange is vertically displaceable, and that at its lower section projecting into the pressure chamber to a Compressed air supply can be connected and with its upper end in one directed against the piston rod in the seat of the cylinder cover provided discharge slot opens.
  • a quick installation or a problem-free replacement of the Shaft pipe internals is according to the invention by several vent pipes ensures that with its upper end in the cylinder cover are attached and together at their lower end Wear the mounting base on which the pneumatic cylinder is fixed is.
  • an im Pressure chamber of the shaft pipe arranged, a quick exhaust valve and a 5/2 way valve block provided, which is connected to an air line supplied from the outside is and via connecting lines with the two chambers of the pneumatic cylinder, with the compressed air reservoir and the ventilation pipes communicates.
  • the device shown is used to selectively shut off Traffic areas and consists of a perpendicular in the ground 1 retractable shaft pipe 2, which at its lower end via a Bottom 3 is closed and one at its upper end Shaft pipe flange 4 carries, together with a surrounding him Flange collar 5 a receptacle for a cylinder cover 6 forms. The latter lies on a cylinder cover gasket 7 and is screwed to the shaft pipe flange 4 using screws 8.
  • a double-acting pneumatic cylinder 9 arranged, which serves to move a piston.
  • the latter is designed as a piston rod flange 10 at the bottom End of a piston rod 11 is arranged by a bottom open tube formed and at its upper end via a piston rod cover 12 is closed.
  • the piston rod flange 10 is guided in the shaft pipe 2 and limits the Pressure chamber 13, which extends into the piston rod 11 up to its Piston rod cover 12 extends.
  • the piston rod 11 protrudes with its upper end through a passage opening 14 of the cylinder cover 6 through, the diameter of the passage opening 14 slightly larger than the outer diameter of the piston rod 11 is so that there is an annular ventilation slot 15.
  • the piston rod flange 10 is vertically displaceable on the ventilation pipes 18 guided and thereby secured against rotation.
  • the ventilation pipes 18 ensure a connection function fast assembly and disassembly of all components relevant components, resulting in quick interchangeability of the entire system.
  • a compressed air reservoir 22 connected to its filling can be connected to a compressed air line 23.
  • each vent tube 18 is a quick exhaust valve 24 provided, through which a rapid pressure reduction of the air pressure built up in the pressure chamber 13 is possible.
  • a valve block 25 is arranged, which is a quick exhaust valve as well as a 5/2 way valve, to one of externally supplied air line 26 is connected and via connecting lines 23, 28, 29, 30 with the compressed air reservoir 22, with the two chambers of the pneumatic cylinder 9 and with the ventilation pipes 18 communicates.
  • a second from the outside supplied air line 27 opens into the pressure chamber 13 and serves to fill it.
  • Each vent pipe 18 has in its upper end portion a bead 31, which serves as a sealing surface for a ball 32 and together with this forms a one-way valve, which is in the Piston at rest is closed and thereby one Penetration of water or other contaminants into the ventilation pipe 18 and prevented in the quick exhaust valve 24.
  • the piston is retracted, i.e. the pressure in the Pressure chamber 13 dismantled, then opens through the ventilation pipes 18 upward flowing compressed air, the one-way valve 31, 32 and flows through the blowout slot 19 directly against the outer jacket the piston rod 11, which is cleaned so that penetration of foreign bodies is prevented.
  • This cleaning effect is amplified when the piston is raised, that the in the shaft pipe space above the piston rod flange 10 located air from the piston rod flange 10 pressed against the piston rod 11 through the ventilation slot 15 becomes.
  • the function of the shut-off device is as follows:
  • the Pneumatic cylinder 9 is pressurized with compressed air in the "stroke" direction.
  • the pressure chamber 13 is via the air line 27 filled with compressed air.
  • the air reservoir 22 is also filled with compressed air.
  • the piston rod flange 10 sealing on the underside the cylinder cover seal 7, whereby the pressure chamber 13 seals becomes. In this case, 27 continues to be air via the air line blown into the pressure chamber 13.
  • the air lines 26, 27 vented. Due to this pressure drop, the Quick exhaust valves 24 opened in the ventilation pipes 18; the compressed air in the pressure chamber 13 is then vented via the vent pipes 18 and the air line 27.
  • the entry movement can only take place when the Pressure chamber 13 is relaxed to atmospheric pressure.
  • the Actual retraction of the piston is then in the Compressed air storage 22 initiated compressed air. Thereby it is ensured that the piston is also in the event of a power failure Can perform downward movement.
  • the volume of the Air accumulator 22 dimensioned so that it is sufficient to the piston to move to its lower end position and its piston rod cover 12 in the seat 16 of the cylinder cover 6 on the arranged there Pull O-ring 17. This is the interior of the shaft pipe protected from environmental influences.
  • the ventilation pipes are used to quickly reduce the pressure in the air pressure in the pressure chamber 13, they act as a tie rod between the cylinder cover 6 and assembly floor 20, they serve as a displacement guide for the piston and prevent its rotation, and they ensure - as already explained above - a quick interchangeability of the entire shaft pipe insert.
  • Figure 2 shows the right half of the cylinder cover in vertical section 6 with its conical seat 16 for receiving the piston rod cover 12, with an upper annular groove 33 for receiving of the O-ring 17 and with the annular blow-out slot 19, in which opens a threaded bore 34 into which the upper end of a Vent pipe 18 is screwed.
