DESCRIPTION:
BRIEF SUMMARY
The invention relates to a jet lance device. A jet lance device is generally used in industry for cleaning dirtied objects. A use is described in the earlier Netherlands patent application 91.01412 of applicant relating to a cleaning lance device for cleaning heat exchanger pipe bundles. This cleaning lance device is known for internal cleaning of the pipes of pipe bundles. The exterior of the pipes of pipe bundles must also be cleaned regularly and a high pressure jet lance device is likewise used for this purpose.
When operations take place with a jet lance handled by an operative no very high pressure can be used. The resulting forces would become too great to be manageable by the operative. In the case of objects that are complicated to clean, such as U-pipe bundles, the cleaning jet must however be held at so many different angles and in so many different positions to achieve a good result that manual operation is unavoidable.
The invention now has for its object to provide a jet lance device with which very complicated objects can also be properly cleaned at a very high pressure and thereby at great speed.
This object is achieved with a jet lance device as described subsequently. The hydraulic crane with the jet member pivotally supported by a rotator forms an industrial robot which can move the jet lance to all desired heights and in all desired directions. Objects for cleaning can be worked on from all sides and in all directions with the high pressure jet, thus enabling good cleaning. Work can take place with a very high pressure so that a very rapid action is obtained. An additional advantage is that the whole device can be remotely operated in the usual manner so that no operative has to be present in the vicinity of the high pressure jet. The risk of industrial accident is hereby markedly reduced.
The invention will be further elucidated in the following description of an embodiment as shown in the figures. Further features of the invention and the advantages obtained therewith will be found in this description.
FIG. 1 shows a partly schematic perspective view of a hydraulic robot jet lance according to an embodiment of the invention.
FIG. 2 shows on a larger scale a part of the device according to arrow II in FIG. 1.
FIG. 3 shows a side view according to arrow III in FIG. 2.
FIG. 4 shows a front view of a part of the device according to arrow IV in FIG. 2.
The device 1 as shown in FIG. 1 comprises a hydraulic robot jet lance according to the invention mounted on a vehicle 2. This robot jet lance comprises a per se known hydraulic crane 3. The hydraulic crane 3 consists in this embodiment of a vertical column 4 rotatable on a vertical axis relative to vehicle 2. A first arm part or first jib 5 is connected to the column 4 at its top end by means of a hinge 7. The deflection of the first arm part or jib 5 relative to column 4 can be adjusted with a hydraulic jack 8. A second arm part or second jib 6 is arranged on the end of the first arm part or jib 5 by means of hinge 9. The angle of deflection of the second arm part or jib 6 relative to the first arm part or jib 5 is adjustable using a hydraulic jack 10.
The second arm part or jib 6 is provided with a telescopic slide member 11 which can be extended and retracted using the jack 12. Mounted on the end of slide member 11 is a head piece 14 which will be described with reference to FIG. 2-4. This head piece 14 bears on its bottom end the actual jet lance 13 which can generate liquid fed via a high pressure hose 16 under high pressure in a jet 15.
The hydraulic crane 3 with two arm parts or jibs 5, 6 shown in FIG. 1 is only one of many possible embodiments. Any suitable per se known hydraulic crane can be applied in the invention. It is only necessary that the position of the end of the arm can be placed in any desired position, of course within reach of the crane, by suitable control and drive means. Also, it can be said that the combination of first arm part or jib 5 and second arm part or jib 6 form what is well known as an articulated jib.
