Abstract

A sewer cleaning device has a rinsing hose, to which pressurized water is applied, which is stored on an assigned storage reel, and which passes through a transportation apparatus adjacent to the storage reel. A manner of operating, which protects the rinsing hose, is achieved by providing a reel arrangement, around which the rinsing hose is wrapped at least once, having two redirection reels arranged laterally adjacent to one another in the radial direction, which are offset in relation to one another in the axial direction by at least the thickness of the rinsing hose and of which at least one redirection reel is arranged tilted about an axis of symmetry, which perpendicularly intersects the axes of the two redirection reels, so that during each complete wrap around the reel arrangement forming the transportation apparatus by the rinsing hose, a pitch of the path assigned to the rinsing hose results.

Claims

1. A sewer cleaning device having a rinsing hose to which pressurized water can be applied, and which can be stored on an assigned storage reel avid which passes through a transportation apparatus adjacent to the storage reel wherein the transportation apparatus has a reel arrangement, around which the rinsing hose is wrapped at least once, having two redirection reels arranged laterally adjacent to one another in the radial direction, which are offset in relation to one another in the axial direction by at least the thickness of the rinsing hose and of which at least one redirection reel is arranged tilted about an axis of symmetry, which perpendicularly intersects the axes of the two redirection reels, so that during each complete wrap around the reel arrangement forming the transportation apparatus by the rinsing hose, a pitch of the path assigned to the rinsing hose which corresponds to the axial offset of the two redirection reels results.

2. The device according to claim 1, wherein both redirection reels are arranged tilted in opposite directions about die axis of symmetry which perpendicularly intersects the axes of the two redirection reels, wherein preferably a pitch corresponding to half of the axial offset of the two redirection reels is provided respectively in the region between running on and running off of the rinsing hose onto or from the respective redirection reel.

3. The device according to claim 1, wherein the reel arrangement forming the transportation apparatus is wrapped around by the rinsing hose multiple times, preferably two times, wherein the redirection reels each have multiple, preferably two circumferential grooves, which are arranged in parallel one behind another in the axial direction and are delimited by lateral flanges, for guiding the rinsing hose.

4. The device according to claim 3, wherein the flanges delimiting the circumferential grooves protrude radially beyond a drum, which forms the groove base of the circumferential grooves and which has a surface structure, which increases the force transmission to the rinsing hose and is preferably formed as teeth.

5. The device according to claim 1, wherein contact, pressure elements are assigned, which are assigned to the redirection reels, are preferably formed as contact pressure rollers, and press against the rinsing hose.

6. The device according to claim 1, wherein guiding elements, which are assigned to the rinsing hose and are preferably formed as guide rollers, are provided in the region of the extension of the rinsing hose between the two redirection reels.

7. The device according to claim 1, wherein the storage reel and the redirection reels are drivable by hydraulic motors, which are connected in parallel during the retraction of the rinsing hose from the sewer, wherein the hydraulic motor assigned to the storage drum has a smaller displacement volume than the hydraulic motors assigned to the redirection reels.

8. The device according to claim 7, wherein, during the unwinding of the rinsing hose from the storage reel, the redirection reels are drivable in the unwinding direction and the storage reel is braked by an assigned pressure reducing valve.

9. The device according to claim 1, wherein at least the redirection reels of the reel arrangement forming the transportation apparatus, and preferably also the storage reel, are each arranged with standing axis and recumbent turns.

10. The device according to claim 1, wherein at least the redirection reels of the reel arrangement forming the transportation apparatus are preferably attached laterally to a pivotable boom.

11. The device according to claim 1, wherein the storage reel assigned to the rinsing hose and also a suction hose reel, which is assigned to a suction hose guided via the boom, are each arranged in the region of the standing pivot axis of the boom with standing axis coaxial thereto and recumbent turns.

12. The device according to claim 11, wherein the suction hose reel rests on the boom, and that the storage reel assigned to the rinsing hose is placed on the suction hose reel.

13. The device according to claim 12, wherein the boom is provided with a step, which results in a niche for the reel packet formed by the suction hose reel and the storage reel.

14. The device according to claim 13, wherein the boom is rotatably mounted on a preferably barrel-shaped container, winch is flattened on at least a part of its length on top to form a niche assigned to the step of the boom.

15. The device according to claim 1, wherein the rinsing hose is equipped on its front end, which is insertable into the sewer, with a sewer nozzle provided with reverse jet nozzles, and can be retracted by the transportation apparatus against the recoil action of the reverse jet nozzles, and that the drive of the storage reel is relieved therefrom.
