"Vehicle, especially truck with a body that can be lifted, Transporting and lowering of reinforced concrete room cells, for example prefabricated garages "

The invention relates to a vehicle, in particular a truck, with a structure for lifting, transporting and lowering lowering of reinforced concrete room cells, for example prefabricated garages, of a guide frame and one in the longitudinal direction of the vehicle has backward movable supporting structure, wherein the guide structure has a bridge that extends at least to the front end of the vehicle and carries rails for rollers of a vehicle, with which an upper section of the shoring is supported on the bridge, while a parallel to the upper and having a lower supporting frame section with rollers connected to this via a central section The trolley is supported on the superstructure, which has a lifting device with several closures for the room cell wearing,

7343991 09/01/77

The vehicle according to the main patent is usually a commercially available, mostly only slightly, for example, in the springs reinforced truck ₅ which is subsequently provided with the structure. This structure enables the transport of spatial bodies which are provided with a one-piece base plate. This is of particular advantage in prefabricated garages because only such room cells can be sealed at the bottom in order to prevent oil and gasoline residues from penetrating the subsurface, which makes a significant contribution to environmental protection, in particular to the protection of bodies of water.

The vehicle according to the main patent sets for its proper Operation in particular also does not have any recesses in the floor of the room unit, because it is on a support of the supporting structure on the ground is completely dispensed with except for the vehicle itself. When used as prefabricated garages The rear end of the vehicle is provided with the space cells in front of the opening with the garage door is lockable. Then the supporting structure is moved so that the section carrying the lifting device gets into the room cell. After the lifting device is connected to the room cell, in particular to its floor is operated. The room cell is thereby raised. The support structure can therefore now be in his Bring the starting position, whereby the room cell passes over the loading area of the vehicle.

During transport, the space cell can be lowered onto the vehicle in order to relieve the lifting device. The unloading or setting up of the room cell requires the reverse sequence of the processes described.

7343991 010977

After, after lifting and before lowering the room module very large lifting forces on the shoring. For example, have room cells that are used as prefabricated garages are, a weight of the order of 10 t and require cantilevered lengths of the supporting structure, the are of the order of 6 m. The main patent provides for the supporting structure to be suspended from a car that rolls with his rollers on rails that are attached to the bridge or form the bridge. It is Although the main patent already provides for the supporting structure to be supported on the structure by means of an additional carriage, however, an optimal introduction of the lifting forces is not present in the construction disclosed in the main patent.

The main patent also has the fact that the construction of the Bridge is too heavy and not strong enough. This is, among other things, a consequence of the construction of the car at the top: Section of the shoring and its attachment. This car extends over the length of the section so that the guide frame must extend to the rear end of the structure. On the other hand is with the main patent provided to make the lower support of the supporting frame only via a pair of rollers, which makes considerable Surface pressures arise, which are compensated for by a correspondingly heavy construction of the structure have to.

Finally, the structure according to the main patent has some disadvantages for the lifting device. This is with the object of the main patent outside of the lower section of the supporting structure on this. That also requires Disadvantages of possible breakdowns, for example

if connections of the lifting device to the room unit are suddenly lost.

The invention is based on a further development of the subject matter of the main patent with the aim of achieving the aforementioned Eliminate disadvantages.

According to the invention "this object is achieved by that the upper and the lower section of the supporting structure each have a horizontal joint with the relevant V / agen are connected and that the upper carriage at the free end of the supporting frame section assigned to it and the other carriage at the end of the lower support framework section that is associated with the middle section of the supporting framework that connects the two sections is appropriate.

It is achieved by the invention that the lifting forces occurring when manipulating a reinforced concrete cell are each other according to the leverage on both cars and fell? represent there as pure compressive or tensile forces. This rests on the possibility of avoiding high surface loads on the guide rails of the guide frame and to avoid compound loads, especially shear loads. The result is a structure, its construction weight is significantly reduced. This is of great importance because of the gross vehicle weight limited, but its exposure is very high.

The simplification of the load conditions of the structure also allows it, according to an advantageous embodiment of the invention to design at least one of the sections of the supporting structure as a carrier of the same strength and the connection joint of the lower carriage in

the vertical projection of the central section to be attached to the supporting structure.

In detail, the invention can be used with appropriate embodiments depending on the type of vehicle to be used add to.

If it is a truck, it should be remembered that the f ~ Headroom is limited and that therefore the height of the ^v construction must be kept small. According to one embodiment of the invention, this is taken into account in that the bridge is supported with a 3y] on and the bridge section extending to one side of the pylon is designed as a lower flange and the bridge section extending to the other side is designed as an upper flange for the carriages of the supporting structure i3t. If you arrange the pylon behind the driver's cab and place the lower flange over the driver's cab, the upper flange lies over the loading area of the vehicle and the guide rails can be arranged lower there. Since these rails are in the room (: cell when the room is charged), the headroom is reduced accordingly when the room is charged.

The pylon should be placed as close as possible to the driver's cab so that the center of gravity of the load is as wide as possible got forward. According to another feature of the invention, the pylon is turned into a tilting device The driver's cab of the truck allowing the distance from this ■ arranged. For trucks with a cab that cannot be tilted the pylon can be moved right up to the rear wall of the driver's cab.

7343991 09/01/77

On the other hand, there is of course also an interest in the Keep construction as narrow as possible. According to the invention it is provided that the pylon is designed as a frame, the stems of which are one of the width of the supporting structure have a corresponding spacing and are connected to the bridge sections, and that the bridge sections of two each from one side of the car and the There are arranged rollers associated with flanged supports, the supports at least of the rear Bridge section are braced with trusses.

It turns out that this also provides sufficient rigidity, in particular of the rear section of the guide frame is achieved, the load conditions after raised and behind the platform of the transport vehicle arranged position of the room unit are particularly extreme, because in this position of the room unit a relatively great moment is transmitted to the jTylon.

It is therefore also expedient to have at least the rear bridge section, which is braced, with one of the two Carrier connecting cover to be provided. According to a preferred embodiment of the invention, this cover consists of a perforated sheet metal.

The structural weight of the supporting structure can be further reduced if, according to another feature of the invention the sections of the supporting structure are designed as box girders. It is particularly favorable that in In this case, the lifting device can be accommodated in the lower section of the shoring. This becomes through it against damage that occurs in rough operation,

7343991 09/01/77

protected. Such lifting devices usually consist of hydraulic cylinders, which are particularly enpfindlidi against dirt, shock and impact loads are.

The box girder is provided according to a further feature of the invention in the area of its lower section with lateral telescopes, in which Um! ¹ , rollers for hoisting ropes are arranged, one of which is assigned to the telescope.

Here, too, the box shape of the carrier enables the sensitive parts of the lifting device to be accommodated in a protected manner. In addition, however, the arrangement of the telescopes has the advantage that they are more or less Extending the telescope far can compensate for the different elongation of the hoisting ropes. This achieves to compensate for inconsistencies in the room unit when it is lifted are.

In addition, the room cell can be moved sideways by the length of the telescope that is available, if you put the telescope on one side z.S. extends and retracts on the opposite side.

This option is a particular advantage because it makes it much easier to set up room cells. The transport vehicle only needs to be steered approximately exactly in front of the installation site because there is an additional possibility of correction due to the ability to move the suspended room cell to the side.

According to a preferred embodiment of the invention, there is

7343991 09/01/77

Lifting device from the least? one, preferably two, lifting cylinders laid in the lower section of the supporting structure; each cylinder carries at the end of its moving part - cylinder or piston rod - a two-armed lever which carries the rest of the ihni associated hoisting ropes at one end one or more hoisting cables and at the other HüTj.ä.s.

The lever has the advantage that it acts as a rope compensation. It cannot be ruled out with absolute certainty that one of the hoisting ropes breaks when the room cell is raised. If that happens, the other hoisting ropes take over the additional weight and the lever swivels to the extent that the load is on the rest of the hoisting ropes distributed. This is a considerable advantage because it avoids overloading the remaining hoisting ropes and serious industrial accidents can largely be ruled out.

Appropriately, the hub; ■■■> .ile is arranged, each of the one side of the support structure arranged telescopes are assigned to a lever of a cylinder, while the the lifting ropes assigned to the telescopes arranged on the other side of the supporting structure to the lever of the other Cylinder of the lifting device.

Expediently, the load on the supporting structure is relieved during the transport of the room cell. Therefore, the structure according to of the invention generally used together with a transport frame with which the structure on the chassis of the Vehicle is supported and the rail for the rollers of the carriage of the lower support frame section and laterally Has extendable supports for the space cell.

7343991 09/01/77

These supports are preferably designed as telescopes and are adjustable. This has the advantage that with different wide room cells support at the most structurally favorable point of the room cell - that is in the Rule Ή «? longitudinal edge lying under the side walls the room cell - can be used.

On the vehicle chassis 6 ″ is a structure whose The lower part is formed by a transport frame 8. The transport frame has two side members 9, the are connected to one another several times by cross members 10, 11 and 12. There are on each side of the vehicle two telescopes 13 and 14 each. The telescopes are among themselves the same, so that it is sufficient to describe one of the telescopes in more detail below:

The inserting part of the telescope is designated 15. and is firmly connected to the associated longitudinal member of the transport frame. The sliding part 16 of the Telescope can be compared to the inserting part 15 mechanically adjust and lock. At its free end it carries a widening 17, which is useful with provided with a support made of a rubber elastic material is because this part is used to set down the reinforced concrete space cell loaded onto the transport vehicle , which is designated by 18. The widening 17 has a bar 19 which extends to the outer edge of the room cell 18 as soon as it is canceled. The adjustability of the inserting and sliding part of the telescope 13 or 14 makes it possible to adapt the support to different dimensions of the room cell.

On the transport frame there are also brackets 22 for hydraulic cylinders 23 at the rear end of the vehicle, the piston rods of which are provided with plates 24. By extending the cylinder 23, the spring ends Turn off both rear axles with tires 4 and 5, whereby the level when loading and unloading the room cell 18 of the transport scaffolding is retained. At the far end
