Definitions

  • the invention relates to a pipe cleaning device, in particular for clogged pipes and drains, with which a pressurized gas, in particular air, is discharged into the pipe to be cleaned.
  • a flexible shaft into the clogged tube for this purpose.
  • a handle is mounted, with the help of which the shaft can be rotated.
  • a suitable device is attached to drill into the blockage. When turning the shaft, the blockage is loosened. In case of success then the particles which caused the blockage can be washed away.
  • a typical representative of such a device is in the DE 82 32 917.6 U1 described.
  • pipe cleaner which are operated with compressed air.
  • the compressed air can come from a print cartridge.
  • inflatable pressure vessels are also known again and again.
  • Such a representative of a pipe cleaning device is in the DE 40 25 196 A1 described.
  • a pipe cleaning device with a pressure vessel for storing air is further in the DE 299 02 897 U1 described.
  • the air can be pumped by means of an air pump or with a compressor in the pressure vessel or the pressure ball described there and then stored there.
  • the air stored in the pressure vessel is then directed into the clogged tube to remove the clog.
  • a device equipped with a compressed air tank which can be filled with air by means of a suitable pump is also commercially available under the name "Pango".
  • the stored in the printing device pressurized air is released suddenly. If this pressurized air is channeled into the clogged pipe, then the "pipe is almost released".
  • a disadvantage of the pipe cleaning devices of the type described last is the fact that they must be inflated until the air pressure in the interior of the pressure vessel has a sufficient value. This makes it necessary to provide safety devices, such as a safety valve, for pressure equalization.
  • Another disadvantage of this known device is that when triggered the pressure at the beginning is highest and then more or less drops, as the stored in the pressure vessel, compressed air expands.
  • a device provided with an exhaust nozzle for the discharge of air for the removal of dust is to provide a cleaning device that is simple and can be reliably removed with the blockages in piping, etc. This object is achieved by a pipe cleaning device according to the teaching of the claims.
  • the pipe cleaning device has a cylinder tube which has an outlet at a first end. To the the other end of the cylinder tube, a piston rod is led out of this cylinder tube, which is connected to a piston located in the cylinder tube. The piston can be moved back and forth in the cylinder tube and is sealed gas-tight. In other words, the movable piston provides a seal between its periphery and the inner circumferential surface of the cylinder tube.
  • the pipe cleaning device according to the invention is further provided with a spring which is arranged such that it exerts a force on the piston in the direction of the outlet in the tensioned state.
  • a spring which is arranged such that it exerts a force on the piston in the direction of the outlet in the tensioned state.
  • the pipe cleaning device according to the invention is equipped with a locking and triggering device which immobilizes the spring in the tensioned state (preferably automatically) or blocked and releases the tensioned spring abruptly when actuated.
  • the spring exerts a force on the piston, this can be done directly or indirectly.
  • the spring acts directly on the piston and is supported for example.
  • the power transmission for example, take place in that the spring acts on the piston rod, which in turn transmits the force to the piston.
  • the cocked spring pushes the piston abruptly in the direction of the outlet.
  • the air present in the cylinder tube is thereby suddenly compressed and expelled from the outlet to the outside.
  • the pressure is built up abruptly by the piston in cooperation with the spring, in such a way that the pressure is increased more and more to the apex.
  • the maximum pressure thus prevails not at the time of actuation of the triggering device but at a later time.
  • the spring is a helically wound coil spring, which is preferably arranged between the piston and the second end of the cylinder tube and is compressed for clamping.
  • a cap through which the piston rod is led out and on which the spring is supported. The other end of the spring is then supported on the piston.
  • the piston is moved in the direction of the second end of the cylinder tube, whereby the spring is compressed.
  • the coil spring preferably runs around the piston rod.
  • the piston rod is guided substantially in the center of the coil spring.
  • the piston is preferably made of an elastic material on its periphery in order to improve the sealing effect between the peripheral surface of the piston and the opposite inner circumferential surface of the cylinder tube, so that the best possible sealing and thus the highest possible pressure build-up occurs when operating the pipe cleaning device according to the invention.
  • an attachment On the outlet of the pipe cleaning device according to the invention an attachment is preferably placed.
  • Such attachments are known and designed such that they are fittingly placed on commercial drains, so that the pressurized air from the pipe cleaning device according to the invention is passed as possible without pressure loss in the pipe to be cleaned.
  • the pipe cleaning device according to the invention is preferably designed in about gun-like.
  • the cylinder tube then represents the gun barrel.
  • the mouth of the gun barrel corresponds to the first end of the cylinder barrel, on which the outlet is placed, which preferably tapers in a funnel shape axially outward.
  • the second end of the cylinder tube is closed by a cap from which the piston rod protrudes outwardly and extends into a gun housing, which is equipped with a handle.
  • the housing is further preferably equipped with a trigger for actuating the triggering device and a clamping lever.
  • the device for tensioning the spring and the locking and triggering device can be realized in a variety of forms. It is only to require that said device is able to tension the spring. Furthermore, it is to be demanded that the locking and triggering device blocks the spring in the cocked position, in particular automatically, and releases abruptly upon confirmation, so that the piston abruptly compresses the air in the cylinder tube.
  • the locking and triggering device can act both indirectly, for example via the piston rod, or directly on the spring.
  • the pipe cleaning device 1 shown partially in longitudinal section in Figure 1 has a cylinder tube 2, which is made of a pressure-resistant material, such as plastic or metal.
  • a cylinder tube 2 which is made of a pressure-resistant material, such as plastic or metal.
  • an outlet 4 which tapers in a funnel shape axially outwards is placed on the cylinder tube 2.
  • the outlet 4 goes to its free end in a hollow cylindrical extension 5, which has on its inner lateral surface a thread into which a thread is screwed, which is screwed onto the outer circumferential surface of a nozzle 6 which is connected to a cap 7.
  • a piston 8 which is movable in the longitudinal direction of the cylinder tube 2 and causes a seal against the inner circumferential surface of the cylinder tube 2.
  • This piston 8 is constructed of a disc (not shown) having on its periphery a circumferential seal 9 made of an elastic material, for example rubber.
  • the seal 9 has on its periphery the contour of an hourglass. The axially inner and outer edges of this seal 9 abut against the opposite inner circumferential surface of the cylinder tube 2. Towards the center of the seal, the diameter of this seal 9 is reduced somewhat so that the shape of an hourglass is produced approximately in side view.
  • a piston rod 10 extends beyond the second end 11 of the cylinder tube 2 addition.
  • This piston rod 10 has on the piston side an abutment disc 12 and is attached to a axially inwardly extending nozzle 21 of the piston 8.
  • the abutment disc 12 serves to support a helical spring 13 which rotates about the piston rod 10 and extends between this abutment disc 12 and a second end 11 of the cylinder tube 2 occlusive cap 23 and is supported on this cap 23.
  • Cap 23, outlet 4, extension 6 and abutment disc 12 are made of a plastic.
  • the cap 23 has axially extending bores (not shown) to allow unimpeded access of air into the cylinder tube 2 from the second end 11.
  • the piston rod 10 is pulled out by means of a device described in more detail below from the cylinder tube 2.
  • the piston 8 comes in the position shown by dotted lines. This position is not an end position but only a central position. The piston 8 can be moved so far to the second end 11 until the spring 13 can no longer be compressed. Under a tensioned state of the spring is understood in the rest of the present documents not only a compressed or compressed spring but also a drawn-in spring.
  • the pipe cleaning device 1 passes at the second end 11 in a kind of housing 14 which is attached to the cap 23.
  • the piston rod 10 extends through this housing 14 and exits at the end opposite the cap 23 from the housing 14 through an opening 15.
  • the piston rod 10 has a rectangular cross section in the embodiment shown in the figures and is movable in the axial direction back and forth.
  • a device for tensioning the coil spring 13 which has a clamping lever 18 which is mounted pivotably about an axis 20 in the housing 14. This axis 20 runs perpendicular to the plane of the paper of FIG.
  • the cocking lever 18 cooperates with a conveyor blade 24 which has approximately rectangular shape in plan view and has a bore 25 through which the piston rod 10 extends.
  • This bore 25 is approximately complementary in shape and size to the outer contour of the piston rod, but has a certain play, so that the conveyor blade 24 can be tilted a certain amount of angle.
  • the clamping lever 18 has approximately the shape of a U-profile, wherein the bottom of this profile to the cylinder tube 2 shows. In the upper region of the clamping lever 18, the bottom is missing, so that two parallel jaws 22 result, between which the conveyor blade 24 is located, with its lower end against the bottom of the U-profile on the side facing away from the cylinder tube side of this soil in Appendix comes.
  • the clamping lever 18 thus engages behind the cylinder tube side, the lower end of the conveyor blade 24.
  • the conveyor blade 24 is tilted and jammed. If the clamping lever 18 is further pivoted in the direction of the handle 17 and thus in the direction of the arrow 26 of FIG. 2, the piston rod 10 is moved in the direction of the arrow 27 of FIG. 2 and taken along.
  • a locking and releasing device is further attached, which holds the piston rod 10 in the respective position or blocks, which can be referred to as a "cocked position".
  • the locking and triggering device has a Arretierblatt 29, which is similar to the delivery sheet 24 and has a bore 30 through which the piston rod 10 extends.
  • the Arretierblatt 29 can be tilted by a certain angular amount until the edges of this bore 30 come into contact with the piston rod 10 and lock this piston rod 10 in the tilted state.
  • Arretierblatt 29 and conveyor blade 24 tilt in the other direction in the opposite direction.
  • the Arretierblatt 29 goes down into a trigger lever 19 and is also the trigger lever side of the piston rod 10 and acted on the clamping lever 18 facing side of the force of a spring 31, which causes the Arretierblatt 29 is pivoted and tilted with the piston rod 10 and thus holds this.
  • the pivot axis 32 for the Arretierblatt 29 lies on the opposite side of the trigger lever 19 and is formed by the Arretierblatt 29 is held by two guides 33.
  • the conveyor blade 24 is acted upon on the side facing away from the cylinder tube 2 by a spring 34 with a compressive force which moves the conveyor blade 24 in the direction of the arrow 28.
  • the other end of this spring 34 is supported on the axially outer guides 16 in the housing 14.
  • Conveyor blade 24, Arretierblatt 29, clamping lever 18, piston rod 10 and trigger 19 are made of a metal.
  • the Kobenstange 10 has an axially extending slot 36 into which a guide pin 37 engages.
  • Such a device for clamping and such a locking and triggering device are otherwise known type.
  • the clamping lever 18 is pivoted several times in the direction of the arrow 26 manually.
  • the piston rod 10 is displaced in the direction of the arrow 27 and held in the displaced position in each case by the locking and triggering device.
  • the catch is released.
  • the piston rod 10 is moved by the tensioned spring 13 abruptly into the cylinder tube 2.
  • the piston 8 compresses the air in the cylinder tube 2 and pushes it under acceleration through the outlet 4 into the clogged pipe or the like.
