Definitions
- This invention relates to a device for operation in pipelines, especially sludge exhaustion of sewers, said device comprising a remote-controlled self-acting caterpillar vehicle, the drive and tension wheels supporting the drive belt of the caterpillar vehicle being vertically adjustable relative to the caterpillar vehicle and pivotably arranged in a vertical plane perpendicular to the direction of travel of the caterpillar vehicle.
- SE-lay-open print 443 522 teaches a self-acting device for disposal of viscous impurities accumulated in tanks for petroleum products, said device having certain basic similarities to the device according to the invention. However, there are also certain extraordinarily important constructive differences thanks to which the device of the invention has an improved function as compared with the known self-acting device.
- Fig. 1 is a schematic lateral view of a caterpillar vehicle according to the invention introduced into a pipeline
- Fig. 2 is a front view of the caterpillar vehicle according to Fig. 1
- Fig. 3 is a front view of the caterpillar vehicle when this is introduced into a pipeline with twice as large a diameter as the pipeline shown in Figs. 1 and 2
- Fig. 4 shows schematically the caterpillar vehicle in connection with sludge exhaustion of a pipeline.
- Figs. 1 and 2 show a caterpillar vehicle 1 when this is introduced into a sewer 2 or the like.
- the caterpillar vehicle 1 comprises an upper member 3 supported by a lower member in the form of two longitudinal frame members 4 via e.g. a lifting means 5 actuated by a pressure medium and arranged in each end of the respective frame member 4.
- the lifting means 5, for example in the form of hydraulic cylinders, are arranged to enable a stepless adjustment of the distance between the upper member 3 and the frame members 4.
- a number of for example hydraulic control and absorbing means 6, preferably two in each end of the respective frame member 4 in the region of the lifting means 5, are arranged between the upper member 3 and the frame member 4.
- the control and absorbing means 6 ensure a rectilinear motion of the frame member 4 relative to the upper member 3 without the risk of wobbling.
- Two drive wheels 7 independent of one another are arranged to enable motion of the vehicle 1 in a desired direction.
- Each drive wheel 7 is operated by for example a hydraulic motor 8 arranged in one end of the frame member 4 and transmits motion to a preferably flexible drive belt 9 running about the drive wheel 8 and a tension wheel 10 arranged at the other end of the frame member 4.
- the tension wheel 10 is preferably freely rotatably mounted in the frame member 4.
- the drive wheel 7 and the tension wheel 10 are pivotable relative to the frame member 4 in a vertical plane perpendicular to the longitudinal axis of the vehicle 1 for adaptation to different pipeline diameters.
- the angle of inclination of the drive and tension wheels 7 and 10 is steplessly adjustable by means of the hydraulic motor 8 in a suitable way not shown.
- a suction hose 12 inserted into the fastening means 11 is shown.
- the suction hose 12 can preferably be connected with the fastening means 11 by the aid of adjustable clamp means (not shown) extending around the suction hose 12. It is shown in Fig. 1 how the suction hose 12 extends along the whole caterpillar vehicle 1 and some distance in front of this and in such a way that the suction hose 12 wi l l be in contact with the bottom of the pipeline 2.
- the vehicle 1 can be provided with other types of tools or instruments than a suction hose.
- the vehicle 1 can be provided with for example root cutting tools, cement mortar isolating tools, welding equipment etc.
- the upper member 3 On its upper side the upper member 3 is provided with for example a hydraulically operated video camera 13 which is rotatable in the horizontal plane around the whole periphery and in the vertical plane about 200°.
- a hydraulically operated video camera 13 which is rotatable in the horizontal plane around the whole periphery and in the vertical plane about 200°.
- the upper member 3 comprises a lifting and towing eyelet 14 i.a. to enable lowering and receiving of the caterpillar vehicle in a pipeline.
- Fig. 3 shows how the vehicle 1 is introduced into a pipeline 2' of twice as large a diameter as the pipeline 2 shown in Figs. 1 and 2. As is apparent from Fig. 3 the distance between the upper and lower members 3 and 4 is greater while the angle of inclination of the wheels 7 and 10 is less than the adjusting position of the caterpillar vehicle shown in Figs. 1 and 2.
- the vehicle 1 is shown in connection with sludge exhaustion of a pipeline 2.
- the caterpillar vehicle 1 is lowered down into a pipeline 2 via a well 15 connecting to the pipeline 2.
- a hydraulic hose 16 comprising a plurality of separate hydraulic lines for driving and operating the vehicle 1
- the caterpillar vehicle 1 is connected with a hydraulic pressure source in the form of the hydraulic system 21 of a truck 17.
- the suction hose 12 is connected with a sludge and suction tank 22 contained in the truck 17. Sludge is brought up by the aid of a strongly dimensioned suction pump, for example a vacuum pump (not shown), arranged in connection with the sludge and suction tank 22.
- the hydraulic hose 16 and the suction hose 12 preferably extend alongside each other with the hydraulic hose 16 placed on top of the suction hose 12 and for this purpose they are combined by the aid of detachable fastening means 18 placed along the hoses at regular intervals.
- simple carriages can be attached at a suitable distance from one another along the underside of the suction hose 12, the frictional resistance being reduced and the propulsion of the caterpillar vehicle 1 facilitated (not shown).
- the vehicle 1 is remote controlled by an operator above ground level via an operating means 19 connected by way of hydraulic lines enclosed in the hydraulic hose 16 with a control unit of the vehicle 1 not shown.
- a control unit comprises the necessary control valves for controlling the hydraulic motors 8, the lifting means 5, the control and absorbing means 6 and the video camera 13 which, further, are connected via hydraulic lines with the hydraulic pressure source 21.
- the caterpillar vehicle 1 can be operated via the operating means 19 in a desired direction and at an optional speed.
- the angle of inclination of the drive and tension wheels 7 and 10 can also be adjusted via the operating means 19 for the current pipeline dimension.
- the position of the suction hose 12 can be adjusted via the operating means 19 by the aid of the lifting means 5 at the desired level above the bottom of the pipeline.
- the caterpillar vehicle is driven and controlled hydraulically.
- the drive and control of the caterpillar vehicle of course also can be carried out for example pneumatically and electrically, the choice of current components such as the motors 8, the adjusting means 5 and the control and absorbing means 6 of course being adapted to a desired drive source.
- the caterpillar vehicle 1 is provided with a radio unit 20 as is most apparent from Figs. 1 and 2.
- inventive caterpillar vehicle 1 is adaptable to work in pipelines of varying dimensions simultaneously as the inventive location of the fastening means 11 enables that the position of the tool 12 relative to the pipeline 2 can be steplessly adjusted so that the tool can always be brought into the desired position relative to the pipeline.
