Description

The invention relates to a water lance blower with a water lance, which is arranged with its mouth on or in a hatch, with a drive system that has at least two drive units for controlling the Has water lance, and with a holding device for attaching the Water lance blower on a wall. Such water lance blowers are used in particular for cleaning heating systems, the Water lance a water jet through the operating and with Flames and / or flue gases flow through the heating system Luke can blow out of accessible wall areas.

Water lance blowers of this type are, for example, in WO 96/38701, the WO 96/38702, WO 96/38703 and WO 96/38704. The Water lance blowers give a bundled stream of water through the Firebox on the opposite wall. As a result of the kinetic Water jet energy and the sudden evaporation of in pores Deposits of water that have entered will cause the contaminants to flake off caused by soot, slag and ash.

The impact area of the water jet generated by the water lance blower follows generally a certain predeterminable way on the to be cleaned Surface, also called a blow figure, this path generally meandering runs and possibly obstacles, openings or other sensitive Excludes zones.

In addition to controlling the drive system using a template, which is mandatory A very specific blow figure was created, especially two-axis controls used with control axes arranged at right angles to one another, in particular a horizontal and a vertical axis, around meandering blow figures easy to generate. As a result, drive systems are more well known Water lance blowers one horizontally aligned and one vertically aligned Drive unit on. At least one of the two drive units is included appropriate devices attached directly to the heating system. The second Drive unit of known drive systems has devices on the basis of which this second drive unit can be fastened on the first drive unit by one To implement two-axis control. The second drive unit is usually like this arranged that they, for example, in addition to the heating system or parts of the Drive system is guided. Such a drive system is for example in the WO 93/12398.

Due to the different requirements according to the desired Fastening or guidance, the drive units are individual, known Drive systems always designed differently. A drive unit is mostly attached to part of a framework. This drive unit moves both the other drive unit and one during operation Water lance and is particularly robust for reasons of stability and rigidity executed. In contrast, the second drive unit is which is articulated in particular to the water lance, to the constructive design of the adapted first drive unit. Specially designed holding and Fasteners are therefore required.

The individual components (such as the drive system, the Water supply line, the control cabinet) known water lance blowers are still so arranged around a centrally positioned water lance that this in Areas outside the swivel range of the water lance are arranged to not to limit the swivel range. In addition, the water lance with a Water supply line connected, which follow the movements of the water lance must and must not restrict them at the same time. Such a water supply Known water lance blowers is therefore immediately after leaving the Water lance led out of the swivel area. For these reasons known water lance blowers require a significantly larger space than the actual one Movement of the water lance required. This is particularly problematic if the location of a water lance blower is of a variety of structural Heating system requirements, such as pipelines, supports, Fittings etc. is limited. It is therefore conceivable that the positioning Known water lance blower at a desired location in the heating system therefore cannot take place because there is insufficient space for the whole Water lance blower is in place, though the required swivel range is Water lance would be guaranteed.

The different versions of the water lance blowers set in high level of logistical effort in the production, sales and distribution Service ahead. A production includes a variety of Manufacturing processes, which differ from the embodiment Drive units are dependent. For this purpose, the most varied Machines and tools as well as specially trained personnel are required.

The object of the present invention is to provide a water lance blower to point out the type mentioned, the space required essentially the Area under the maximum swivel range of the water lance corresponds to that is easy to assemble and maintain and is the same as the logistic above Requirements for a company are reduced, taking the water lance along predeterminable blow figures can be controlled at different speeds.

The object is achieved by a water lance blower according to claim 1. Further advantageous configurations are in the dependent claims described.

The water lance blower according to the invention has a water lance that on the one hand with its mouth on or in a hatch is pivotally arranged and on the other hand is connected to a water supply system. The Water lance can create a water jet through the operating and using Flames and / or flue gases flow through the heating system Blow reachable wall areas. The water lance is replaced by a Drive system controlled by two drive units and thus allows the Generation of any blow figures by the water lance. Furthermore, the Wasserlanzenbläser a holding device that is used to attach the Water lance blower is used on a wall of the heating system. This Holding device is characterized in that parts of it Water supply system are integrated.

By integrating parts of the water supply into areas of the Water lance blower located close to the water lance is the Water lance blowers are particularly compact. The holding device provides also a kind of adapter between a mostly rigid one Water supply and a flexible, flexible transfer of water to Water lance out there. The forwarding is only in a relatively small Section moves, which requires less force to move the water lance and the space in which parts of the water lance blower move is clear is reduced. This reduction in the range of motion results in that when positioning the water lance blower according to the invention elaborate adaptation of the water supply system to the structural Conditions of the heating system is no longer required.

Accordingly, it is particularly advantageous if the holding device has at least one connection device for a separate water supply line. In particular, the use of standardized connection devices advantageous, whereby the water supply lines can be rigid to Example as line pipes. Furthermore, the holding device has at least one Connection element for a flexible line for passing water to Water lance. The design of the connection element is flexible and depends on the type of water transmission to the water lance, whereby the desired swivel range of the water lance is not restricted.

It, the holding device with at least one distributor is particularly advantageous perform, which divides a flowing water flow and the Connects water supply with at least two connection elements. A large Water inflow can thus be divided into several water flows, whereby an application-oriented design of the more flexible water supply Water lance is possible.

According to an advantageous embodiment of the water lance blower is in the Holding device integrated at least one valve. The valve serves the Regulation of the pressure generated in the nozzle of the water lance, whereby the Quality of the water jet generated in connection with a control unit Operator can be influenced in a simple manner.

According to a further embodiment, the flexible line is from Holding device to the water lance designed as a flexible hose system, the water flow being divided into two or more parallel hoses. The Distribution of the water flow can either be within the Holding device, such as with a distributor, or by the Hose system itself. Splitting the water flow into two or more hoses leads to significantly lower bending radii of the hose system and thus contributes to the compactness and flexibility of the water lance blower.

It is particularly advantageous to design the hose system with four hoses, which are arranged so that each tube with its cross-sectional center is arranged on the corners of an imaginary square. In this way preferred bending directions of the hose system are generated, which aligned according to the desired movements of the water lance can be. The hoses can be replaced by simple means, e.g. Cable ties can be fixed in this arrangement.

According to a further development, the hose system has three or more Hoses run with their cross-sectional centers on a straight line are arranged. The alignment of the hose system is so that Adjust the water lance's movements so that the friction on the Hose walls is as low as possible.

According to a further embodiment, the hose system has one Jacket hose that at least partially surrounds two or more hoses. This can be particularly the case, for example, due to bending or contamination sub-areas of the hose system. Particularly advantageous it is when the jacket hose is lubricated inside (e.g. talc) is provided, which is essentially between the jacket hose and the Hoses distributed. This will result in a bending stress Friction on the outside of the hose walls reduced.

It is particularly advantageous if the parts integrated in the holding device of the water supply system is concentrated in one corner of the drive system are arranged. This way the water lance's range of motion is not limits.

Particularly advantageous, regardless of the other design of the Holding device, it is when the water lance blower two drive system Has drive units, which are characterized in that they are modules are trained. This means that the drive units are functional in themselves Form units and as such are completely interchangeable. So trained identical drive units in a drive system are therefore also interchangeable. This has the advantage that, for example, during the drive unit is easily removed for repair and replaced with a new one Drive unit can be replaced. A modular embodiment of the Drive units also reduce the logistical expenses of a Company, which is now only a reduced number of variants Manufacture, store or logistically manage drive units. This significantly reduces the manufacturing and service costs of the Company.

Furthermore, such a structure of the drive system supports one compact and simple arrangement of the water lance blower. The attachment of the Holding device on a heating system can thus be in the desired position be made. Starting from this position, the Drive units can be arranged arbitrarily, so that if necessary with Regarding components of the heating system, the drive units like this be combined that a desired swivel range of the water lance is realized.

The first and second drive units are arranged perpendicular to one another and connected to each other, the first being connected to the holding device and the second drive unit is moved by the first. The second Drive unit drives the water lance so that its end area during the Operation can cover a maximum projection area. This results in an arrangement of the drive units in the marginal positions of the travel the first drive unit L-shaped and in a central position of the travel path Is T-shaped. The alignment of the L- or T-shaped arrangement is irrelevant. A frame is not required for such an arrangement. The arrangement of the integrated parts of the is advantageous and particularly preferred Water supply system in the area of a corner of the projection surface of the Water lance.

According to a further embodiment, the second drive unit of the Drive system executed with a connecting element, the side with one end protrudes from the second drive unit. With this end of The water lance is articulated to the connecting elements. The connecting element is to be carried out so that the freedom of movement of the water lance is not is restricted. The connecting element is arranged such that the protruding end to the side of the drive system of the water lance blower is aligned, that of the holding device, in particular with integrated parts of the water supply system.

This orientation of the connecting element has a very compact and space-saving water lance blowers, because in this way the Drive units and the holding device essentially on one of the rear end portion of the water lance swiveling surface are arranged. The connecting element is through the two drive units in one plane moves and thus enables the movement of the water lance. Due to the the articulation point of the water lance varies Connecting element. If the water lance inclines sharply (if, for example both drive units are close to an edge position), the articulation point moves in the outer area of the water lance to the flexible pipe. At a upright position the articulation point is closer to the mouth of the Water lance. Furthermore, certain devices must be at the outer end be provided for fastening the flexible line, which the Do not restrict the water lance's freedom of movement. For these reasons the water lance is not at its outer end with the connecting element is articulated, but extends further beyond the articulation point. This extreme end of the water lance sweeps during operation of the Water lance blower a maximum area on which to match aligned connecting element both the drive units and the Holding device arranged with integrated parts of the water pipe system are.

According to a further embodiment, the modular drive units have each have at least one motor, one spindle and one spindle nut. The The motor is connected to the spindle and thus rotates the during operation Spindle, which translates the spindle nut mounted on the spindle is moved. Such drive units are for precise path control particularly suitable. In addition, they are characterized by their simple structure.

According to a further development, the water lance blower has a guide system with slide shoes and rails. The spindle nut is with the Connected slippers. The sliding blocks are made by means of two parallel rails guided. The rails are attached directly to the drive unit and so aligned that these run parallel to the spindle. In this way the Bending and torsional rigidity of the drive unit increased.

It is particularly advantageous to use the motors of the drive units as EC motors (electronic communication). EC motors can do this accordingly be optimized for their intended use and thus enable a reliable Control of the spindle nut. These motors are also characterized by low heat generation, high speeds and the possibility of Detection of the speed to determine the distances covered by one Spindle connected spindle nut. It is particularly advantageous if, in addition to control the water lance by the motors of the drive units Water lance is designed with a motion sensor, which malfunctions in the Motion transmission reports.

According to a further development, the sliding shoes have a fastening unit connected. The fastening unit is either with the number of Connected sliding shoes, which are moved translationally on a rail, or it is connected to the total number of shoes. if the Fastening unit is connected to all slide shoes, this represents a kind Platform that covers an area between the rails and the Spindle nut fixed. A fastening unit designed in this way increases clearly the torsional rigidity of the drive unit.

According to a further embodiment, the fastening unit has Positioning aids for exact alignment of the fastening unit attachable structures. The fastening unit is a kind of interface to the structures that are moved by the drive unit. such Structures are, for example, another drive unit that Connection element for fixing the water lance or components which Represent part of a tour of the heating system. The exact path control of the Water lance along given blow figures at any speed requires an exact alignment of these structures on the drive unit. With Such positioning aids avoid assembly errors.

It is particularly advantageous to use the positioning aids as pins, grooves or bores perform. These positioning aids can also be attached to a mounting unit be mixed in any combination. The positioning aids enable appropriate design of the structures to be fastened a kind Form fit and thus support the fixation of the structures in one definable position.

According to a further development, a first is attached to the fastening unit Drive unit a second drive unit fixable. That means the second Drive unit is designed such that it is on the fastening unit can be fastened by, for example, a cooperation of positioning aid and the second drive unit is guaranteed. So two are modular executed drive units simply to a two-axis control for one Water lance blowers mountable.

According to a further embodiment, the drive unit has a cage-like Profile rail and a cover. The cage-like profile rail and the Cover at least partially enclose dirt-sensitive components the drive unit. For example, the Motor, the spindle, the spindle nut, as well as the parts of a translational Guide system with slide shoes and rails. Because of the mounting location the drive system for a water lance blower to a high degree exposed to a wide variety of environmental conditions. The high proportion of soot or ashes in the ambient air as well as any leakage or Splash water is in this way from the spindle and guide system kept away.

The rails of the guide system are on the cage-like profile rail attached. The side walls of the profile rail at least partially enclose the Rails and the sliding shoes guided on them. The cover is above the Arranged and extends substantially between the Side walls of the profile rail. The arrangement of profile rail and Coverage is preferably such that the inner and dirt-sensitive components are almost completely enclosed.

It, the fastening unit outside the cage-like is particularly advantageous To arrange profile rail. A connection of the fastening unit with the Slide shoes inside the profile rail is designed so that inner areas of the profile rail sealed against contamination are. The spindle and the guide system are thus protected, and the Fastening unit also offers an external connection option.

The arrangement of profile rail and cover described has the Formation of at least one gap. This gap is necessary to the movement of the spindle nut on external structures, especially the Water lance of the water lance blower, to be transferred. According to another Embodiment, the drive system has at least one bellows is arranged so that this at least partially at least one gap between the profile rail and cover seals. It is particularly advantageous Bellows on the front side with the cage-like profile rail as well on the other hand to connect with the fastening unit. The bellows is there in particular additionally guided on the profile rail and thus covers the at least one gap between profile rail and cover.

According to another embodiment, the bellows is not with the movable attachment unit, but serves as protection during the downtimes of the water lance blower. That means the bellows too Start of a cleaning cycle of the water lance blower moved into one position in which it only extends over marginal areas of the gap and after End of the cleaning cycle is stretched again and thus the covers at least one gap up to the fastening unit. This Embodiment is particularly well suited in conjunction with additional ones Sealing devices on the gap, which during the operation of the Water lance blower prevents contaminants from entering the inner areas of the Prevent drive unit.

According to a further embodiment of the water lance blower, there is at least one Slide shoe each connected to a rail with a boat. The Fastening unit between the slide shoe and boat as well as on the the side of the boat facing away from the sliding shoes. If that at least one boat serves as an interface with other structures this is preferably equipped with positioning aids. Is under a boat to understand an elongated structure, which is at its narrow ends so tapered that a wedge shape is created. The boat is in a crack arranged between the mounting rail and cover and thus protrudes over the Cover out.

Areas between fixed parts of the drive units, such as the profile rail or the cover, as well as the movable parts (Fastening unit or boat) are according to a further development of the Drive system with sealing device. Because of the operation of the Accelerations and speeds occurring in the water lance blower. the sealing devices are robust. Furthermore, the Sealing devices adapted to the external environment, in this Connection especially the temperature insensitivity of the Sealing device is in the foreground, since the drive system is mostly direct is attached to the heating system.

According to another, the profile rail and the cover point Design type rubber lips, which extend over the column and on fit the boat. Preferably, the rubber lips are designed so that the rubber lips of the profile rail and the cover of a gap touch each other at least partially. With a translatory movement of the The spindle nut becomes the boat between the rubber lips of a gap moves, the wedge shape of the boat opens the rubber lips. Such executed rubber lips seal the gap between the cage-like Profile rail and the cover and thus protect internal areas.

Another particularly advantageous embodiment of the water lance blower has to seal the gap of the drive unit on two tapes. The tapes are connected to the profile rail and the cover and extend over the gap to be sealed. Between these bands, the moveable Structure led. It is particularly advantageous to use an outwardly directed band Metal using an inward facing rubber band. The tapes lie in areas remote from the movable structure and open up near the position of the moving structure. The metal tape, for example good protection against ash, etc., while the flexible and elastic Elastic band adapts particularly well to the movable structure.

According to yet another embodiment, air is in the profile rail Overpressure can be introduced. The air escapes essentially through the gaps between profile rail and cover. Because of the airflow inner areas of the profile rail to the outside is the penetration of Dirt and soot from the surroundings of the drive system are prevented.

According to a further development of the water lance blower, the Holding device by integrated control elements for at least one Drive unit or for training and monitoring a water jet. These control elements influence, for example, the speed of the engine or regulate the water flow blown out by the water lance.

It, the holding device with control displays and / or is particularly advantageous Equip controls with which the Control elements can be influenced. In this way, the Water lance blowers checked and controlled on site by an operator become. The integration of the control elements as well as the control displays and Control elements leads to a very compact embodiment of a Drive system for a water lance blower.

According to a further development, the holding device has connections for one Remote control and / or external diagnosis. That means, for example, that Control elements via a bus system with a remote diagnostic station is designed to be connectable and thus remote monitoring of the functioning of the water lance blower is possible.
