Description

The present invention describes a heated pressure washer the preamble of independent claim 1.

High-pressure cleaners are known from the prior art, the one Have base body on which a heat exchanger together with a High pressure pump is built. There is also a water connection the high pressure pump feeds. Furthermore, it is known to be corresponding To install control units for heating the heat exchanger. These worry ensure that by actuating a spray lance, for example, that the flowing water is heated by the heat exchanger and by the High pressure pump is compressed into a high pressure range. This heated up and pressurized water can then be sprayed onto a spray lance appropriate surface to clean it.

Such high-pressure cleaners are used, for example, in the construction industry or wherever dirt can be removed under high pressure or should. As is known, such a system can also be dirt-removing Means are added so that an improved cleaning effect is achieved can be.

One possible area of application is the construction industry Construction industry, it is known high pressure cleaner for example for floor and Facade cleaning or the like to use more work.

To do this, it is often necessary to use the pressure washer above certain To transport obstacles to the site. It can also be possible that the pressure washer from one level, such as the Ground of a courtyard, on another level, for example on a terrace or to be raised or lowered into an underground car park.

Especially on construction sites, there is often the possibility of existing ones on site Use lifting equipment for the transport of the high-pressure cleaner. It is often also the only way to get a high-pressure cleaner anywhere spend where it is needed, because on construction sites often still difficult Terrain forms are available. That means either there are no ways yet trained or the paths are not yet passable or there are only stairs in place, making the pressure washer either with an enormous effort must be transported over certain distances, or that it must be transported without Lifting device can not be brought to its place of use at all. In In such a case, it would be necessary to set up far away from the site and incredibly long distances for the high pressure line using individual Form hose pieces. This is neither desirable nor sensible.

In most cases, an on-site lifting device is used to bring the high pressure cleaner to the appropriate place of use. at the previously known embodiments of pressure washers existing lifting equipment more or less cheaply or unfavorably on the High pressure cleaner attached and this raised. However, there is always the risk that the high pressure cleaner either slips or, in worst case even slips out of the lifting mechanism and falling.

On the one hand, this leads to the high-pressure cleaner being endangered damage, and on the other hand to endanger the surrounding People.

Regarding the damage or destruction of the pressure washer at this point it should be noted that high pressure cleaners also in must be serviced at regular intervals so that this is their optimal Can guarantee function. It is necessary to do this at least once Year to maintain the coil of the heat exchanger. This requires the Take the heating coil out of the jacket of the heat exchanger and to wait accordingly.

The heating coil itself is now a structure made of a bent steel tube, which, according to its name, in a serpentine winding is wound up, the two ends of which are appropriate for the supply or discharge of the conducted water to be heated.

Because of this structure, the heating coil naturally also weighs accordingly heavy. For the maintenance of a pressure washer it is therefore necessary to have appropriate lifting equipment available, which is often only available in special equipped workshops. Otherwise the heating coil must be lifted out of the heat exchanger by several people. This is not a satisfactory solution. On the one hand, the injured persons involved, on the other hand, the high-pressure cleaning device take damage. Another disadvantage is that there are several People are required to get the heating coil out of the heat exchanger to be highlighted, or back into them after maintenance bring in.

In addition to the dangers set out above, this also represents the disadvantages maintenance becomes costly and time consuming.

The object of the present invention is so a high pressure cleaner to further educate that it is easier and safer to use with simple means and is waiting.

This task is solved by the technical teaching of the independent Claim 1.

The present invention now proposes to achieve the object, to design a high-pressure cleaner so that on a base body Central tube is attached, which is roughly in the focus of the Pressure washer is positioned. This central tube is intended for High-pressure cleaner with the components already mentioned in the introduction, and optionally other components, so to stabilize and reinforce that the pressure washer itself by means of this central tube can be loaded. For this purpose, it is provided that the central tube is designed in such a way that that this is approximately at a right angle from a base plate or the like, such as for example a frame. On that, the base plate opposite end of the central tube, a receptacle is now provided, in which, for example, a lifting anchor can be arranged and fixed. To the appropriate arrangement and fixation of the lifting anchor can High pressure cleaner using the lifting anchor through an existing one Lifting device raised and / or over any number of floors be lowered.

The lifting anchor is designed such that it has, for example, an eyelet that is suitable for hanging a crane hook. So it is very easy to use the entire high-pressure cleaner on any crane hook anywhere the device is to be used.

The central tube is now so stable that it can be used together with the Base body or the base plate a solid base for the pressure washer formed. In addition, the high-pressure cleaner can now also be used with the appropriate mobile substructure. That means that he can use appropriate wheels and have associated axes so that it can be moved or rolled can. For this purpose, the body can optionally have two, three or even four wheels have, by means of which the pressure washer is good on an approximately flat surface can be moved. Of course, this is also steerable.

However, the features essential to the invention relate to the central tube, which is suitable for the entire high pressure cleaner, if necessary with all possible additional components to lift or to be able to lower.

Another feature essential to the invention with regard to the high-pressure cleaner is that the central tube is designed to be a lifting device record, which is suitable for the heating coil of the heat exchanger Lifting repair or maintenance purposes out of the heat exchanger, to move them away from the heat exchanger and then drain them again can.

The device can be used, for example, as an attachable lifting device be trained. It is designed as an independent aid, which is designed, for example, as a tube on which a thickening is provided is so big that it cannot slide into the central tube, so that only part of the tube forming in the base body of the lifting device in the inside of the central tube can slide in. The pipe that slipped in which represents the main body of the lifting device, can then around its Longitudinal axis are rotated, the thickening on the top of the Central tube slides along. To facilitate such a swivel movement can, for example, a plain bearing between the central tube and the Support surface of the lifting device may be provided.

The lifting device itself can now be in the form of an angled or bent tube be formed, such as the shape of a Has light pole. On the outside line for the curvature of the tube Now, for example, a winch can be arranged, which may be over additional pulleys leads a rope, so that a attached Load suspension device, for example in the form of a hook, on one Can attack mounting bracket, which is connected to the heating coil or is fixed to it. By pressing the Cable winch can now heave the heating coil out of the heat exchanger become. If the heating coil is free of the heat exchanger, can the entire device can be pivoted so that the heating coil is not hovers more over the heat exchanger, but somewhere to the side of these, so that it can be lowered onto the floor unhindered.

This will make life much easier for maintenance purposes Pressure washers achieved according to the invention both in terms of Security as well as enormous advantages in terms of time and financial aspects offers.

For reinserting the serviced heating coil or one if necessary new heating coil must be carried out in the opposite way.

The lifting device can be used again after maintenance or repair be removed from the central tube and, for example, as a maintenance tool a service car. Thus, with a single Any type of high pressure washer can be serviced on which a corresponding receptacle in the form of a central tube is trained.

As a further advantage of the present invention, that the central tube also serves to further important components of the To keep the pressure washer fixative. For example, the Heat exchanger itself can be fixed by means of a fastening to the central tube.

Further components or means can also be arranged on the central tube so that even high pressure cleaners with several different Components can be fixed and stabilized by the central tube, or even so that a corresponding structure can be realized.

The present invention will now be described below with reference to those in the appendix attached drawings described in more detail.

FIG. 1 shows a schematic structure of a high-pressure cleaner 1 in oblique top view. For this purpose, on a base body 2 approximately in the middle, that is in Area of focus of the pressure washer 1, a central tube 3 with the Base body 2 connected. On the central tube 3 by means of a fastening 4 Heat exchanger 7 additionally attached or fixed. Another is shown High-pressure pump 11, which has a high-pressure line 10 with the heat exchanger 7 combines. Mobile means are shown on the underside of the base body 2, which in the present case from the impeller 12 with the corresponding axis and Support wheel 13 exist with a corresponding recording. This Devices are part of the prior art and are only the here Completeness given.

However, the structure of the high-pressure cleaner 1 is essential to the invention by means of the base body 2 and the central tube 3 firmly connected thereto Central tube 3 now serves to build up the high-pressure cleaner 1 so stably that he lifted it at a single point using a lifting device can be. This lifting also makes it possible to use the high-pressure cleaner lower to a desired location or raise to higher floors. Important in the present invention is that the central tube 3, its name accordingly, it is arranged in a central location essentially in the area the focus of the pressure washer. This ensures that that when the pressure washer is lifted, it neither slips nor can pivot. This means that the high-pressure cleaner is safely loaded by means of a suitable lifting device.

In Figure 1 it is further shown that a cover 8 around the jacket of the Heat exchanger 7 is placed around. In this cover 8 there is a Exhaust 9 arranged from which the exhaust gases of the heat exchanger flow.

The illustration in FIG. 1 is, of course, not a conclusive one Representation of a fully functional pressure washer thought, special merely as a schematic representation to explain the present invention and their main features.

FIG. 2 again shows a base body 2, but in this case without it mobile lower parts. The central tube 3 is in turn on this base body 2 arranged. This time the view is shown from the other side. Essential in this illustration, the attachable lifting device 20, which in the Recording 6 of the central tube 3 is inserted. The support 24 can For example, as a disc connected to the lifting device his. You can also thicken the lifting device at this point represent. Basically, this support is not mandatory because the attachable lifting device can also be designed so long that it up to the bottom of the central tube is sufficient.

However, the lifting device advantageously has a support 24, below which may also have a bearing arranged to pivot it to facilitate the attachable lifting device 20. Of course this can however, also omitted, and only lubricated material by material or material walk on material with grease.

The lifting device 20 now has, as in the illustration in FIG. a vertical, tubular formation, which in, from the central tube 3rd opposite area is kinked at the end. This kink forms so-called "gallows". This gallows now advantageously extends into the Middle of the heat exchanger 7. On the line of the lifting device 20, which the A kink winch 21 is arranged. To this Cable winch 21, a rope 19 is wound up. This rope 19 is shown in FIG Figure 2 processed so far that it is guided over two pulleys 22 and on End of the gallows down, hanging towards the center of the heat exchanger. At the end of the rope 19 is a load suspension device 18, in the form of a hook educated. This hook now hangs partially from the heat exchanger 7 pulled out the heating coil 14. The heating coil 14 hangs on one Mounting bracket 17, which with the two connections 16 of the heating coil connected is.

The heating coil 14 can now in the mounting direction 15 from the heat exchanger be moved out or into it.

For this purpose, it is provided according to the invention that only a single person by operating the cable winch 21, the hitherto only under appropriate dangers maintenance work to be carried out on the heating coil 14. If the heating coil 14 by means of the lifting device 20 and its associated Aids 18, 19, 22 completely pulled out of the heat exchanger 7 , it can be swiveled in accordance with the swivel direction 23, that it is no longer above the heat exchanger 7, and thus on an empty space can be drained onto the floor.

The maintenance work, both on the heat exchanger 7 and on the heating coil 14 can thus be carried out. It is no longer necessary how so far that either in the hall in which the maintenance work is carried out is a locally available lifting device for lifting the Heating coil 14 is required from the heat exchanger 7, or that instead such a lifting device cumbersome and under several people the heating coil from the heat exchanger have to lift out.

Regarding the winch, it is also stated that this is also a backstop may have installed.

Furthermore, from the illustration in Figure 2, the attachment 4 for a additional fixation of the heat exchanger to the central tube 3 shown.

FIG. 3 again shows the representation of the base body 2 on which the Central tube 3 is arranged. This illustration shows that the Lifting anchor 26 is connected to the central tube 3. On the representation of the other components for the high-pressure cleaner 1 have been omitted here. at this representation is only about the explanation of the functional features regarding the lifting of the high-pressure cleaner by means of the inventive Central tube 3 in cooperation with the lifting anchor 26. The lifting anchor 26 has an eyelet 28, in which a crane hoe can be hung. The complete high-pressure cleaner 1 can then be moved in the lifting direction 27 be raised. Of course, in the opposite direction High pressure cleaners can also be drained off.

The securing bolt 25 serves to ensure that the lifting anchor 26 is firmly locked in place is secured. This ensures that the high-pressure cleaner 1 is reliable and safely to any location using an external lifting device can be raised or lowered.

Figure 4 shows the third essential feature of the present invention. she in turn represents the base body 2 on which the central tube 3 is fastened.

Here, the central tube 3 serves additional additional means on the central tube Fasten. For this purpose, a receptacle 29 is shown, on which another means is attached. This is a blower 30, which is used for this additionally supply air for the combustion process in the heat exchanger, so that better efficiency is achieved.

Of course, it is also possible to use electrical units such as a transformer, a control box, a control unit or the like to install. Basically, it is possible to use any additional for the operation of the Pressure washer 1 required units at least attached to it. However, many of these devices can also work completely alone on the central tube 3 be attached. The fixation is of course carried out according to sensible Aspects.

In summary, it can be stated that the Construction essential to the invention of the high-pressure cleaner 1 on a base body 2 with a central tube 3, a basic framework is provided, which Both the possibility offers the pressure washer 1 at a single point to record with a lifting device and this anywhere to spend, as well as to use the same point to add another, to install independent lifting device 20, for example to Perform maintenance work. In addition, the central tube 3, which is of course correspondingly stable, as well as a place for additional ones Means to operate the pressure washer.
