Description

The invention relates to an assembly and repair device for vehicles, in particular for construction and commercial vehicles, such as trucks according to claim 1.

Assembly and repair facilities with corresponding lifting devices for lifting vehicles, especially trucks are known per se.

Such lifting devices are mounted in the prior art on a rim or floor of assembly or repair pits, which are usually formed as concrete tubs.

The associated installation effort is perceived as relatively high. In particular, such assembly and repair devices according to the prior art are perceived as relatively inflexible.

The DE 201 14 804 U1 discloses a mounting cassette for a hydraulically operated motor vehicle underfloor lift and a built-in such a mounting cassette underfloor lift. The steel cassette comprises an inner and an outer cassette, which may be formed as a steel cassette. There is a thermal barrier coating on the inside of the outer steel cassette. Between this thermal barrier coating and the inner steel cassette a concrete layer is present. The space between the two steel cassettes is filled by the thermal barrier coating and the concrete layer. The WO 2006/112857 A2 relates to a device for lifting motorized vehicles. A lifting device is positioned in a carriage. This carriage allows movement of the lifting device within a support structure.

The JP 2005 138698 A discloses a device for lifting vehicles with a mounting pit. The mounting pit can be covered by a variety of individual elements.

The DE 43 45 415 C2 discloses an assembly and repair pit with a usable in a bottom recess one or more parts cassette made of steel.

The invention is based on the object to show an assembly and repair device, which is associated with a low production cost and in particular can respond flexibly to different requirements or adjusted. This object is achieved by an assembly and repair device according to claim 1.

This object is achieved by an assembly and repair device for vehicles with all technical features, in combination, from claim 1.

This device comprises a usable in a bottom recess one-piece or multi-part receiving cassette made of steel or the like corrosion-resistant material with two longitudinal side walls, end side arranged end walls and a bottom, preferably the side walls each have an inner wall and a spaced apart therefrom outer wall defining a cavity into which a curable filler material can be introduced through an upper opening, and at least one lifting device for lifting vehicles, in particular lorries, which is integrated at least partially, in particular at the manufacturer side, into the receiving cassette.

An essential point of the invention is that the receiving cassette and the lifting device are matched to one another, in particular the manufacturer, that the lifting device is integrated into the receiving cassette. As a result, the assembly cost is significantly reduced, especially if receiving cassette and lifting device already prepared by the manufacturer accordingly.

Preferably, the bottom has an inner bottom and an outer bottom arranged at a distance therefrom, which delimit a cavity into which a hardenable filling material such as concrete or the like can be filled. The exterior floor can be just like the aforementioned Outer walls either as an integral part of the cassette or by optionally removable formwork boards od. Like. Be formed. By such a double bottom or a total of such double-walled receiving cassette, the fluid-tightness thereof is substantially increased. It is a primary and secondary security guaranteed. Preferably, the inner wall and / or the outer wall of the side walls and / or the inner bottom and / or the outer bottom is fluid-tight.

The assembly and repair device comprises at least one first lifting device, which is movable within the receiving cassette in the vehicle longitudinal direction. As a result, the assembly and repair device can be flexibly adapted to vehicles, in particular trucks with different wheelbases. The lifting device may then have a relatively small extent in the vehicle longitudinal direction. The lifting device can thus be made smaller overall, which saves material and manufacturing costs.

The term "vehicle longitudinal direction" (also X direction) should be understood in this context as the direction that is defined by the direction of travel of the vehicle when driving straight ahead. The "vehicle transverse direction" (also Y-direction) should be understood to be perpendicular to the "vehicle longitudinal direction". Transferred to the assembly and repair device and its elements, these terms "vehicle longitudinal direction" and "vehicle transverse direction" refer to the way in which the respective devices and their elements are approached by the vehicle.

The assembly and repair device comprises at least one second lifting device which is fixedly installed with respect to the vehicle longitudinal direction. The second lifting device is disposed within the receiving cassette, but may, unclaimed, be located outside the receiving cassette. In conjunction with the at least one first lifting device, the assembly and repair device can be flexibly adapted to different wheelbases. For example, in the case of a two-axle vehicle, the front axle can then be placed over a lifting device fixedly installed with respect to the vehicle longitudinal direction, with the rear axle being placed on, for example, a first lifting device already correspondingly moved in advance (or vice versa). Alternatively, it is also conceivable to provide several or exclusively movable lifting devices and to dispense with respect to the vehicle longitudinal direction stationary lifting devices. It can be provided for an axle of the vehicle, a single lifting device or alternatively for an axle of the vehicle two lifting devices (ie per wheel one) or be provided more. The lifting device does not have to be designed to be attacking on wheels of the vehicle, but alternatively may be designed to engage other elements such as the chassis of the vehicle.

Preferably, at least one lifting device is movable in the transverse direction of the vehicle and / or changeable with respect to its extent to the vehicle transverse direction. As a result, the assembly and repair device can be particularly easily adapted to different gauges of vehicles to be measured. In particular, when the at least one first lifting device is movable in the transverse direction of the vehicle, it is virtually any (within the limits imposed by the design) in an X- / Y-plane (which is defined by the vehicle longitudinal direction X and the vehicle transverse direction Y) movable and thus special flexible. Alternatively, however, the at least one first and / or at least one second lifting device - in terms of a structurally particularly simple embodiment - be installed fixed in relation to the vehicle transverse direction.

Preferably, at least two lifting devices with respect to the vehicle longitudinal direction offset from each other, in particular arranged one behind the other / can be arranged. This is particularly advantageous for vehicles having more than two axes.

In a specific embodiment, the assembly and repair device has a drive unit, in particular arranged within the receiving cassette, which is designed for moving at least one lifting device in the vehicle longitudinal direction and / or vehicle transverse direction and / or in a stroke direction. This facilitates handling of the assembly and repair facility. In particular, it is possible to move several lifting devices in parallel and / or synchronously. Alternatively, it is conceivable to provide separate drive units for the process in the vehicle longitudinal direction and / or vehicle transverse direction and / or stroke direction for each or each of the lifting devices. Drive units can be provided which can move one or more lifting devices exclusively in one direction. Alternatively, drive units can be provided which can move the same or the same lifting devices in several directions, for example simultaneously in the vehicle longitudinal direction and in the vehicle transverse direction or the vehicle transverse direction and the stroke direction or the vehicle longitudinal direction and the stroke direction or in all three directions.

The assembly and repair device comprises at least one support strip, by which the receiving cassette on the upper side at least partially, in particular completely covered / is covered, wherein optionally a part of the cover is formed by a top of at least one lifting device. By way of example, the receiving cassette can be covered / covered by the supporting strip band and possibly an upper side of one or more lifting devices to 20%, preferably to 40%, more preferably to 60% and in particular to 70%. By the support band can be prevented that people fall into the receiving cassette and come to harm. In addition, the falling in of dirt in the receiving cassette is reduced or completely prevented. If the recording cassette is not completely covered, it is possible to relatively easily get into the recording cassette to perform, for example, maintenance or repair work on the assembly and repair facility or perform assembly and repair work on vehicles from the recording cassette. Instead of a support band, another covering means, for example a grate, which can be designed to be displaceable or foldable, can be used. If the receiving cassette is completely covered, corresponding opening devices, for example in or on the lifting device or within the receiving cassette, can be provided for any required maintenance or repair work on the assembly and repair device or the carrying beam strip can be provided with closable openings such as flaps or sliding devices.

Preferably, the same drive unit is provided for moving at least one lifting device and the support beam band. For example, the lifting device can be driven directly via the drive unit and the support bar strip indirectly via the lifting device. Alternatively, the support beam can be driven directly and the lifting device indirectly via the support beam. Further alternatively, it is also possible to drive the lifting device and the support beam band via separate coupling devices by the same drive unit. Characterized in that the drive unit is provided both to drive at least one lifting device and the support beam band, the space requirement of the surveying device is reduced in each case and facilitates a synchronous tuning of the movement of lifting device and Tragbalkenband.

In the assembly and repair device, a first end of the support beam band is connectable / connected to a first end of the at least one first lifting device, wherein the support beam band is deflected via deflecting devices such that a Lifting device connectable / connected, wherein the support beam band is deflected over deflecting devices such that a second end of the support strip is connectable / connected to a second end of the at least one first lifting device, so that only by the at least one first lifting device and optionally by at least one connecting element in that, for example, an interrupting or otherwise circulating support bar strip is formed / can be formed by a tensioning device. This embodiment makes it possible in a particularly simple manner and independent of the position of the first lifting device that the receiving cassette is always closed on the upper side. Any kind of retraction or extension of the support strip in a receiving device is not required due to the return, so that appropriate recording devices are not required, which saves further space. It is also conceivable to insert and / or extend a carrier strip or several carrier bars into corresponding receiving devices.

Preferably, a maximum travel of the at least one first lifting device in the vehicle longitudinal direction is at least 4 meters, in particular 7 meters, preferably wise 9 meters and particularly preferably 11 meters. This further increases the flexibility of the assembly and repair facility.

The support band is preferably passable. In particular, the support beam band can be designed such that it carries a vehicle with a weight of 1, 5 tons, preferably 5 tons, more preferably 7 tons and in particular at least 15 tons.

In a concrete embodiment, at least one first lifting device and / or the supporting beam band are / is movably mounted / received on / in separate guiding devices. As a result, the strength or maximum load of the respective guide devices can be adequately adapted to the different loads of the support beam band or the lifting device. Alternatively, it is also conceivable that the lifting device and the support bar strip run in the same guide rail / guide rails.

In a development, the assembly and repair device comprises a reading device, via which vehicle characteristics can be read out. As a result, the effort for setting the assembly and repair device is reduced, especially when one considers that many vehicles, especially new vehicles, often have their characteristics including center distance and wheelbase stored on a corresponding characteristic card. In this context, the term "reading device" should be understood to mean that any device can be meant, can be read on the appropriate data or processed in some other form. By way of example, such a reading device can also be a PC which reads out the data via an archive preferably made available via the Internet or an intranet. In question come as a reader and usual scanner devices that can read, for example, data from magnetic and / or smart cards.

Preferably, at least one lifting device is mounted on the longitudinal side walls of the receiving cassette arranged guide rails. Thereby, the weight of the corresponding lifting device including the weight of a vehicle placed on the lifting device is discharged to the side walls of the receiving cassette, which relieves the bottom of the receiving cassette. Also, unevennesses in the floor area do not lead to a lack of function of the corresponding lifting device.

1. a) Auslesen von Fahrzeugkenndaten, insbesondere Auslesen des Radstandes und/oder der Spurweite,
2. b) Verfahren mindestens einer Hubvorrichtung einer Montage- und Reparatureinrichtung entsprechend den ausgelesenen Fahrzeugkenndaten,
3. c) Positionieren mindestens eines Elementes des Fahrzeuges auf einer entsprechenden Hubvorrichtung.

An adjustment, in particular presetting of the assembly and repair device may comprise the steps:

1. a) reading of vehicle characteristics, in particular readout of the wheelbase and / or the gauge,
2. b) the method of at least one lifting device of an assembly and repair device in accordance with the read vehicle characteristics,
3. c) positioning at least one element of the vehicle on a corresponding lifting device.

In step a) a scanner or PC can be used. The PC can then be connected to a network, for example, or read the corresponding vehicle characteristics via a corresponding USB port, a CD drive or the like. Accordingly, the vehicle identification data on memory cards such as magnetic or smart cards or USB sticks or other electronic storage means can be provided. Of course, the reading of the vehicle characteristics can also be done manually. In step b), the method of the lifting device according to the read-out vehicle characteristics preferably preferably automatically or alternatively manually.

In the following description, the same reference numerals are used for the same and like parts.

Fig. 1 shows an assembly and repair device in a view from above. The mounting and repair device comprises a receiving cassette 10 with two longitudinal side walls 11, two end side walls 12 and a bottom 13. The receiving cassette 10 is preferably made of stainless steel or the like corrosion resistant material and may be provided with anticorrosive and / or fluid-repellent coatings. In the receiving cassette 10, a support beam 14 and a first and a second lifting device 15, 16 is added. The first lifting device 15 and the support beam band 14 are movably received in the vehicle longitudinal direction X (see for directional information Fig. 1 ; the vehicle transverse direction is marked Y).

The support strip 14 is deflected via a first and second deflection device 17, 18. The first deflection device 17 is located in the vicinity of a foot-side end 19, wherein the second lifting device 16 is located between the first deflection device 17 and the foot-side end 19 and the side wall 12 assigned to the foot-side end 19. The second deflecting device 18 is located at a head end 20 of the receiving cassette 10th

The first and second deflection device 17, 18 are covered by deflecting covers 21. The Umlenkabdeckungen 21 are provided on the upper side with an anti-slip coating 22.

Within the receiving cassette 10 in the region of the first deflection device 17, a drive unit 23 is mounted (see in particular Fig. 4 ). The drive unit 23 comprises an electric motor 24 whose drive power is transmitted to the first lifting device 15 via gearwheels 25 (only one of which can be seen in the figures), which are arranged on the edge side, on the carrier bar band 14 and via the carrier bar band 14.

The support strip 11 comprises a plurality of support beams 26 (see Fig. 4 ) and is in an associated support band guide rail 27 (see Fig. 5 to 6 ) held displaceable.

At both end faces of each support beam 26 are rectangular recesses 28 (see Fig. 5 ), so that the respective support beam band 26 has a T-shaped structure.

By the juxtaposition of the individual rectangular recesses 28 in juxtaposed support beam 26 11 longitudinally extending grooves are defined in the side regions of the support beam. In these grooves extend two, in the longitudinal direction of the receiving cassette 10 extending bush conveyor chains 29 (in FIGS. 5 and 6 only hinted at). Each support beam 26 is associated with a respective chain link of the Buchsenförderketten 29. Between each two subsequent chain links of the Buchsenförderkette a joint is provided, which is associated with a respective gap between the support beam 26.

The individual chain links of the bush conveyor chain 29 are by means of bolts 30 (see Fig. 6 ) connected with each other. On this bolt 30 guide rollers 31 are mounted, which roll on the respective support beam guide rails 27.

The Buchsenförderkette 29 are at the foot-side end 19 and at the head end 20 each two gears 25 (of which only one is visible in the figures) assigned. On the bolts 30 of the chain links come successively corresponding recesses of the gears 25 and are moved upon confirmation of the gears 25. In this way, the support strip 11 and thus also the first lifting device 15 are moved depending on the operation in a desired direction.

The support beams 26 have at least on the underside a trapezoidal cross-section, so that a hinge connection between adjacent support beams in the region between the top and bottom of the support beam 26 is possible.

The individual support beams 26 have grooves 32 and springs 33 (see Fig. 4 in the range of the gear 25), which make it difficult or impossible to prevent the ingress of dirt or foreign bodies.

The first lifting device 15 is movably received in separate Hubvorricltungsführungsschienen 34 via corresponding guide rollers 35 (see Fig. 4 ). In the present case, the term "rail" should not necessarily be understood as an elevation, but generally as a bearing surface or receiving element for corresponding sliding and / or rolling elements. If necessary, the "rails" can also be surveys.

Interrupting within the support beam 14 or this one or more tensioning devices, for example in the form of turnbuckles may be provided (not shown in the figures).

The longitudinal side walls 11, the end walls 12 and the bottom 13 are each double-walled with a cavity arranged therebetween for receiving hardenable filling material, such as lightweight concrete or the like, each formed at a longitudinal distance from each other arranged hole walls 36 (see Fig. 5 ) are inserted stabilizing between each inner and outer wall.

The guide rollers 35 of the first lifting device 15 may be detachably mounted, with fine adjustment in conjunction with the corresponding lifting device guide rails 34 in the millimeter range may be possible.

The Umlenkabdeckungen 21 may consist of sheet steel and be firmly mounted with associated side supports.

The support beams 26 and the support beam band 14 may be equipped with an anti-slip coating (in particular on the upper side). The support beams 26 are preferably designed as multi-chamber light metal hollow sections.

Preferably, the first lifting device 15 is carried by an associated support beam 14, but may run completely autonomously in its own guide rail (such as the lift device guide rail 34).

The lifting devices 15, 16 can be moved in such a way in a stroke direction that they are movable under the support beam 14 and thus by the support beam 14 are completely covered (see for stroke direction Z. Fig. 3 ).

It should be noted at this point that all of the parts described above are considered to be essential to the invention and in every combination, in particular the details shown in the drawings, as essential to the invention. Variations thereof are familiar to the person skilled in the art.
