EP3135343B1 - Vehicle with hose winding device - Google Patents

Description

The invention relates to a vehicle with hose winding device according to the preamble of claim 1.

With the publication EP 2 756 870 A1 a Schlauchwickelvorrichtung is shown, which consists essentially of a cylindrical drive roller. The drive roller is driven by a motor and has a frictional resistance, whereby a hose can be pulled out of a container of a vehicle provided for this purpose.

Hose winding devices are also known from the prior art, which are arranged on or on a roll-off container. Roll-off containers or roll-off containers are preferably used by the fire department as a swap body. Hereby, a removable loader vehicle can pick up the roll-off containers, transport them to the point of use and, if necessary, set down there. A roll-off container is always equipped for a specific application and can be used, for example, for the extraction of firefighting water or for leaching at high tide.

The Wechseladerfahrzeug is preferably designed as a truck with a total weight of more than 20 tons. Due to the heavy weight of the removable vehicle (WLF), it was only possible to drive on paved roads or solidified roads to the place of use or water supply point.

In the roll-off container, the pump unit is housed as a separate module. Up to now, it has only been possible to transport the pump unit in rough terrain to the water intake point, which required at least two emergency services. In addition, the hydraulic hose for driving the pump as well as the pressure hose (eg F-pressure hose) had to be carried to the water supply point.

With coupled pressure hose, the pump is inserted floating into the water. In some cases, a hydraulically driven cable winch is used as protection when the pump is being pumped in and when the pump is returned to the container. For this purpose, however, the roll-off container always had to be placed within reach of the maximum cable winch length, which has often been difficult due to non-fixed paths.

After discontinuation of the pump unit, the Wechselladerfahrzeug continue driving to the point of fire, while a line of pressure hoses from the roll-off container will move.

When the mission is completed, the shuttle vehicle travels from the scene of the fire to the water intake point. During the return journey, the laid hose lines are resumed with the help of a hydraulically driven hose receiving device in the roll-off container. For this purpose, at least four emergency services are required, which operate the hose receiving device and lay the hoses clean inside the container.

A disadvantage of the embodiment according to the prior art is that the container is very large and therefore always has to be carried by a separate, relatively heavy truck. The truck can only drive on paved roads and park the container only on a solid surface. As a result, the locations are very limited or lost during use important minutes by the settling of the container and wearing the pump unit.

Furthermore, the hose winding device forms a unit with the container, whereby the container can only be transported together with the hose winding device.

With the US 2008/0271901 A1 discloses a vehicle with a hose winding device for the loading and unloading of at least one hose line in or from a vehicle-side container, wherein the vehicle has a lifting unit to which the hose winding device is arranged. The vehicle is in this case designed as a forklift truck with tires, wherein a person is always while driving on the vehicle and this controls.

Object of the present invention is now to develop a hose winding device such that it can be easily and flexibly brought to any location.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is now that a lifting unit is arranged on an off-road vehicle, which has a hose winding device.

With the embodiment according to the invention, it is thus possible for the first time to easily transport the hose winding device even on non-fixed paths, whereby important minutes can be saved during use of the fire department.

The all-terrain vehicle has a lifting unit, which preferably consists of a lifting mast and a fork carriage. The fork carriage carries two horizontally spaced, adjustable tines, which are vertically movable by means of a hydraulic. Instead of the mast as a lifting unit and Teleskophubarme possible, whereby lifting heights of more than 3 m can be achieved.

Furthermore, instead of the fork carriage on the lifting unit, for example, loading and mixing blades, blades with hydraulic hold-down, heavy duty crane hooks, hydraulic winches, a lattice mast with and without winch, a work basket or an aerial work platform can be arranged.

The combination of an off-road vehicle with a lifting unit achieves an all-terrain forklift truck, which is preferably designed as a counterbalance truck, wherein the engine in the rear region of the vehicle represents a counterweight for the load to be absorbed in the front region of the truck.

The all-terrain vehicle has, for example, a length of 2,330 mm and a width of 1,350 mm. Its own weight is about 2.2 tons, so that the vehicle can easily be recharged onto a trailer or easily lifted by a crane.

According to the invention, the off-road vehicle has a chain drive. The focus is on all variants of the off-road capability, which is achieved by a high ground clearance, high traction and an extremely robust construction of the chassis and the mast, and a strong motorization.

The drive for the all-terrain vehicle is a combustion or electric motor. The internal combustion engines work with a propane / butane mixture (liquefied petroleum gas), diesel fuel or natural gas.

In a further preferred embodiment, a hose winding device is arranged on the lifting unit. The hose winding device is used primarily for removing and removing the hose from a moving container. The container is located on the forks.

The container may be formed, for example, as a hose box, large box or foldable container. Preferably, the container has the basic dimensions of a EURO pallet, which are 1200 * 800 mm and can be easily attacked by the fork tines due to the special design of the soil.

The hose winding device can be active or passive. The present invention means under an active hose winding device on the one hand the pure manipulation of the hose. This means that the hose is in direct contact with and pulled out of the device. However, it is also possible with the hose winding device to pull a (wire) rope. Thus, not only a hose can be manipulated with the hose winding device according to the invention, but also a rope to which different objects can be hung.

The active hose winding device is preferably designed as a winch, which is driven mechanically, electrically or hydraulically. Such winds are already known from the fishing industry, with which the nets are pulled on the deck of a ship.

In a passive embodiment, the present invention means manipulation with a non-powered device. This can be, for example, rotatably mounted rollers or winches, which allow easy guidance of the hose.

In a preferred embodiment, the all-terrain vehicle has a track drive and a mast. In the upper part of the mast an active hose winding device is arranged.

A significant advantage of the embodiment with a lifting mast is that not only a box can be unloaded from a vehicle, but the hose winding device can be driven due to the off-road capability of the vehicle to any point of use. For example, it is possible that the hose winding device serves as a winch for a wire rope, to which a submersible pump is attached. At the front end of the forks is preferably another role over which the wire is guided.

With the embodiment according to the invention, it is now possible to drive the all-terrain vehicle together with the submersible pump and the hose to a harbor basin edge, to lift the submersible pump over the harbor wall with the mast and then to leave with the winch in the water.

Preferably, the drive of the all-terrain vehicle is suitable to supply the submersible pump with the necessary energy. For example, the submersible pump can be operated with hydraulic or electric power.

Through the mast and the hose winding device arranged thereon, it is thus possible for the first time to lift a submersible pump over a railing or a wall and finally lower it. This was not possible until now, because the Submersible pump was either worn or was pulled only with the help of a remote winch on the ground.

Overcoming a wall attachment or a railing could not be guaranteed by the emergency services due to the high weight.
In a further preferred embodiment, the hose winding device is arranged on the forks. The power supply of the device then takes place with connection cables or hoses to the all-terrain vehicle.

Furthermore, the lift unit can pick up a fork tine extension with the forks. This has the significant advantage that the off-road vehicle can be parked at the harbor edge and now with the help of the fork tine extension the submersible pump can be deposited far into the harbor basin.

In a further preferred embodiment, the lifting unit can pick up a container with the forks. The container is designed to accommodate the tube, with different container sizes for different tube sizes or hose lengths are possible. It is crucial that the all-terrain vehicle with the lifting unit can lift the container from a truck and then transport on a dirt road.

The container may further comprise at least one tread and a safety railing for at least one deployment force. The tread is hinged and can either be firmly connected to the container or even temporarily be infected to the container.

It is crucial that the off-road vehicle after use when retrieving the hose moves backwards, so that the forks are located in the rear of the vehicle. This prevents a deployment force from being rolled over by the vehicle. Furthermore, the container must be lifted when driving only a maximum of 20 cm from the ground, so that also accidents by a possible fall of an emergency force can be avoided.

After a container with a hose is full, it can be lifted with the lifting unit in a truck. Furthermore, it is also possible that the parked only on the ground and is then lifted with a crane on a transport vehicle.

What is important in the invention is that the vehicle is an all-terrain vehicle capable of both driving to remote pumping stations and hoses to unpaved areas, e.g. Swamp or a moist surface can transport.

This was not known from the prior art, since in each case a truck with a large roll-off container was necessary, which is very heavy and can only drive on paved roads.

In a further preferred embodiment, a booster pump can be arranged on the off-road vehicle, which in particular amplifies the pressure of the submersible pump and thus just higher pressures at the end point of the hose can be achieved.

In a further preferred embodiment, in the case of the off-highway vehicle, a fan can be arranged in the region of the lifting fork or in the area of the lifting mast, which is moved upward over the vehicle during use, so that it is supplied with sufficient air.

In a further preferred embodiment, the off-road vehicle in addition to the fan still have additional water nozzles in the flow direction, whereby the air flow water is added. This creates a spray that is particularly effective in firefighting. Furthermore, foam can be added instead of the water, so that the foam is distributed over a large area due to the flow volume of the fan.

The fan can in this case have its flow direction either in the direction of the forks or in the direction of the drive. In an arrangement in the direction of the drive, the water mist would also cool the drive unit of the all-terrain vehicle from the fire heat.

Furthermore, the off-road vehicle can be equipped with a water cannon, wherein preferably the booster pump in the area of the vehicle serves to supply the fire extinguisher with the additional water pressure.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

With the FIG. 1 schematized the off-road vehicle 1 in the embodiment is shown as a self-propelled vehicle. The chassis 4 is designed as a chain drive (= crawler track) 18 and attached to a body which consists essentially of a support tube frame 17.

The vehicle 1 is through the crawler 18 an ideal device for extreme operations away from paved roads. The preferred drive for the vehicle 1 is a diesel engine.

The vehicle 1 has no driver's cab or driver's cab, but is remotely controlled. The remote controllability of the vehicle 1 has the significant advantage that the vehicle 1 can be made substantially smaller, since no guide post is necessary for a person traveling. In addition, can the vehicle 1 have a much higher off-road capability, since the total weight and the center of gravity are significantly reduced.

At the front end of the support tube frame 17 of the vehicle 1, a lifting unit 2 is arranged, which allows lifting and lowering the forks 3 relative to the support tube frame 2. The lifting unit 2 can either mechanically, electrically or hydraulically move the forks 3 vertically up and down.

The forks 3 are preferably foldable and can be folded up during the empty travel of the vehicle 1 or in the loaded state of the vehicle 1 on a loading area of a truck or trailer.

According to the FIG. 1 is located in the upper region of the lifting unit 2, the hose winding device 5, which is preferably designed as a winch. With the winch is not only an operation ie targeted guidance of a hose 6 possible, but also the guiding of a rope 25, which may be formed as a wire rope. Guiding means the present invention that the hose 6 or the cable 25 is not only pulled, but also can be discharged specifically.

The arrangement of the hose winding device 5 on the lifting unit 2 with forks 3 has the significant advantage that a separate hose container 7 can be accommodated and the hose 6 located therein moved from the container 7 to the ground and be merged again from the bottom into the container 7 can.

The all-terrain vehicle 1 also makes it possible for the hose lines 6 to be laid quickly and effectively away from paved paths and to be collected again after the end of use.

With the FIG. 2 the vehicle 1 is shown with folded forks 3. The forks 3 is spaced from each other on a lifting unit 2, which is designed as a telescopic mast.

The support frame 17 of the vehicle 1 has crane hook receptacles 13 at a plurality of locations, to which the vehicle 1 can be attached and thus to e.g. can be loaded on the back of a trailer.

The FIG. 3 shows the off-road vehicle 1 with a lifting unit 2, on which a container 7 is arranged for receiving a hose 6. The hose 6 is pulled for laying using the hose winding device 5 from the container 7 and transported in the direction of the rear of the vehicle. In the region of the rear of the vehicle, the vehicle 1 has at least one further guide roller 12 for selectively guiding the hose line 6.

The container 7 is used for the logistics of the hose 6. In the region of the end faces, the container 7 has special openings for optimum removal of the hose line 6 from the container 7. Preferably, the container 7 is designed so that it can be stowed in it hose material for a circa 500 m long hose line 6.

The container 7 has in the bottom area on lateral recesses, which allows the vehicle 1, with the forks 3 to undercut the container and then raise. At the upper, circumferential edge of the container 7 also has crane hook receptacles 13, which also allow easy lifting with a crane.

With the FIG. 4 a removal of the hose 6 is shown from an end opening of the container 7. In this removal process of the hose 6 no hose winding device 5 is necessary. The laying of the hose 6 is done exclusively the emergency services.

The hose winding device 5 then comes again when collecting the hose 6 into the container 7 is used.

FIG. 5 shows the container 7 for the hose logistics. The basic dimensions of the container 6 are preferably 1200 * 800 mm. On the side surfaces of the container 6 in the bottom region of treads 22. The treads 22 make it possible to join the forces during the drive of the vehicle 1. As an additional safeguard, the container 6 still has a securing railing 23.

With the FIG. 6 a further embodiment of the off-road vehicle 1 is shown. The vehicle 1 has an additional booster pump 9, which amplifies the supplied water pressure of a submersible pump 8 again. Both pumps 8, 9 are preferably powered by the drive unit of the vehicle 1 with energy.

With the FIG. 7 the all-terrain vehicle 1 is shown in the region of a wall projection 15 of a water tapping point. The wall projection 15 may be, for example, a harbor wall. Under a wall projection 15, the present invention includes all vertical elevations, such as a railing, a fence or the like.

The hose winding device 5, in this embodiment, a rope 25, which hangs the submersible pump 8. With the help of the hose winding device 5, the lifting unit 2 and the cable 25 a targeted lowering of a submersible pump 8 behind the wall projection 15 is possible.

The vehicle 1 is located in the vicinity of the wall projection 15 and has a fork tine extension 14 on its forks 3. The fork extension 14 is plugged onto the forks 3 or can be undercut and lifted like a pallet.

By lifting unit 2, the wall projection 15 can be overcome in vertical height. With the help of the fork tine extension 14, it is then possible to selectively lower a submersible pump 8 only after the wall projection 15 into the water.

In a preferred embodiment, the fork tine extension 14 has at least one guide roller 24 for the cable 25 at its front free end. The supply of the submersible pump 8 via a supply line 16, which is connected to the vehicle 1.

So far, it was hardly possible to lift a heavy submersible pump 8 over such a wall projection 15 and then selectively lowered into the water.

With the FIG. 8 the off-road vehicle 1 is shown with a lifting unit 2, which has a pressure aerator 10. The pressure aerator 10 (also high-pressure (fan) fan or overpressure aerator) is always used to smoke-free smoke-free rooms or houses or to keep non-smoke-filled building parts smoke-free.

The FIG. 8 shows the fan 10 in the lowered state, which corresponds to the general driving condition.

According to the FIG. 9 is the fan 10 raised by the lifting unit 2 on the floor plan of the vehicle 1 in the direction of arrow 11, so that a free flow of air is possible.

Of course, instead of the fan 10, other firefighting equipment can be arranged on the lifting unit 2. Thus, for example, a combination of the lifting unit 2 with special jet pipes, showerhead pipes, Löschlanzen, Wenderohre, monitors or high-pressure jet pipes is possible.

The FIG. 10 shows again the off-road vehicle 1 during use. Starting from the emergency vehicle 20, the off-road vehicle 1 is driven independently through an unpaved terrain 19 to a water outlet 21.

The water removal point 21 is secured by a vertically extending, raised projection, so that the vehicle 1 has lifted its lifting unit 2 to lower the submersible pump 8 in a horizontal distance to the wall projection 15 into the water by means of a fork tine extension 14.

The all-terrain vehicle 1 is thus a multifunctional device, which is not used for laying out and collecting hose lines 6 can be, but also a submersible 8 can settle in hard to reach places.

In addition, the off-road vehicle 1 always provides a power supply for the hose winding device, the fan, the submersible pump or the booster pump.
