Method and cleaning device for cleaning the interior of pipes
A method for cleaning the interior of pipes using a cleaning device and a cleaning device. The cleaning device has a tube and an advancing unit for moving the tube along a main axis (H) of the advancing unit. The advancing unit has a drive which is frictionally connected to the tube and by which the tube is moved in an axial direction along the main axis (H). The advancing unit is set into a rotational movement about the main axis (H) during the axial movement of the tube, and the drive transmits the rotational movement to the tube.
1 . A cleaning device for cleaning the interior of pipes, comprising:
a tube,
a post and
an advancing unit for moving the tube along a main axis (H) of the advancing unit, wherein the advancing unit has a drive connected to the tube by a frictional connection in order to move the tube axially along the main axis (H),
wherein the advancing unit is rotatably supported about the main axis (H) in the post,
wherein the tube can be set into a pendulum movement by the frictional connection, and
wherein a pendulum drive is provided, by which the advancing unit can be rotated.
2 . The cleaning device according to claim 1 , wherein the drive comprises one or more rollers, which are frictionally connected to the tube.
3 . The cleaning device according to claim 2 , wherein the advancing unit has a pinion by which the advancing unit can be rotated about the main axis (H).
4 . The cleaning device according to claim 3 , wherein a controller is connected to the pendulum drive and the drive.
5 . The cleaning device according to claim 4 , wherein the pendulum drive has a rack-and-pinion transmission, wherein the rack-and-pinion transmission has the pinion and a rack that can be moved back and forth on the post, and wherein a linear movement of the rack is converted into a rotation of the pinion and thus of the advancing unit by the rack-and-pinion transmission.
6 . The cleaning device according to claim 5 , wherein the rack can be moved linearly using two single-acting lift cylinders or using a double-acting lift cylinder, wherein the lift cylinder(s) are supported on the post.
7 . The cleaning device according to claim 6 , wherein the pendulum drive has a pneumatic motor supported on the post or a servomotor, by which the pinion can be rotated.
8 . The cleaning device according to claim 7 , wherein the advancing unit comprises a tube guide, that is interrupted in the region of the drive.
9 . The cleaning device according to claim 1 , wherein the advancing unit has a pinion by which the advancing unit can be rotated about the main axis (H).
10 . The cleaning device according to claim 1 , wherein a controller is connected to the pendulum drive and the drive.
11 . The cleaning device according to claim 1 , wherein the pendulum drive has a rack-and-pinion transmission, wherein the rack-and-pinion transmission has the pinion and a rack that can be moved back and forth on the post, and wherein a linear movement of the rack is converted into a rotation of the pinion and thus of the advancing unit by the rack-and-pinion transmission.
12 . The cleaning device according to claim 11 , wherein the rack can be moved linearly using two single-acting lift cylinders or using a double-acting lift cylinder, wherein the lift cylinder(s) are supported on the post.
13 . The cleaning device according to claim 1 , wherein the pendulum drive has a pneumatic motor supported on the post or a servomotor, by which the pinion can be rotated.
14 . The cleaning device according to claim 1 , wherein the advancing unit comprises a tube guide, that is interrupted in the region of the drive.
