In one aspect there is disclosed a pipe cleaner assembly (10) operatively adapted to be located within a pipe obstructed with plant material. The pipe cleaner assembly (10) includes a cutting head (12) longitudinally extending about a cutting head axis (16) between a driving end (18) and a cutting end (20). The cutting head (12) defines a driving element slot (22) operatively adapted to hold an elongate driving element. The pipe cleaner assembly (10) further includes a cutting formation (14) operatively secured to the cutting head (12). The cutting formation (14) outwardly extends from the cutting end (18) of the cutting head (12) so that in use torque applied to the cutting head (12) by the driving element causes the cutting head (12) and as a result the cutting formation (14) to rotate about the cutting head axis (16) to cut plant material within the pipe.

A system for maintaining conduits and pipes after their installation into a pipeline system used to transport material in a fluid or flowable form. The system includes a maintenance tool adopted for use inside the pipe, an umbilical attached to the maintenance tool for pulling the tool through the pipe; and a pluralities of bearings positioned around the umbilical in order to allow the tool to be pulled through the pipe around bends and turns in the pipe.

A drain cleaning device includes a drum, and a cable positioned within the drum. The cable is operable to be extended out of the drum and into a conduit. The drain cleaning device also includes a motor coupled to the drum to rotate the drum, a sensor operable to detect a characteristic of the cable, and a controller coupled to the sensor and the motor. The controller is configured to receive a signal from the sensor indicative of the characteristic of the cable and send an instruction to the motor to change an operating parameter of the motor based on the signal received from the sensor.

The present invention discloses a single-drive bidirectional-crawling pipe-cleaning robot, including a front body assembly, a transmission assembly, and a rear body assembly. The transmission assembly is driven by a single power source, and a transmission effect of a connecting rod mechanism, a gear mechanism, and an equal-dwell cam mechanism is used to implement alternate retraction and support of the front body assembly and the rear body assembly in a radial direction and a telescopic motion in an axial direction between the front body assembly and the rear body assembly and at the same time implement synchronous rotation of a dredging cutter head, so as to implement bidirectional crawling and pipe cleaning work of the robot along a pipe. The present invention is stable, reliable, compact, and practical, and implements single-drive bidirectional crawling and pipe cleaning in a pipe having a greatly changing pipe diameter, so that the obstacle negotiation performance and adaptability to pipe diameter changes of an in-pipe robot are effectively improved, the endurance of the in-pipe robot is improved, and practical engineering significance in cleaning of a horizontal pipe having a greatly changing pipe diameter is provided.

The group of inventions can be used for removing deposits B sewers and their simultaneous removal of various pipelines and cleaning process provides mechanization and sewage pipe work, eliminate the need for disassembly of the drain system and manual cleaning. With actuator mounted outside sewer pipe, is moved along the sewer c associated drive the movable member and fixed therein Ha cleaning tool arranged within the sewer pipe. In the initial position will cleaning tool located at the end of the sewer pipe portion is sewer piping connecting the drain pipe to the riser. Upon reaching the final cleaning tool in the positions of the junction of the sewer with the riser and c by the drive of the movable member is moved scraping tool to its original position.

A root cutter collar with quick changing skids preferably includes a base tube, a plurality of skid bosses, a plurality of skid retainers, a plurality of threaded fasteners and a plurality of skids. The plurality of skid bosses are attached to an outside perimeter of the base tube. A pair of tapped holes are formed through each skid boss.
