Description

The invention relates to a post-treatment machine according to the preamble of claim 1, as well as a method according to the preamble of claim 13.

Such construction machines are for example from the EP 1 841 637 A known, in the form of a brush spraying machine, with a newly created concrete pavement of a road surface using z. B. a brushing unit can be textured and then sprayed using a spray unit with a liquid post-treatment agent.

In the production of a concrete pavement, especially in the construction of concrete pavements, the concrete is usually installed by a Gleitschaltungs paver form and correct position and this with a smoothing device, eg. As a cross straightener, smoothed. In some cases, a longitudinal smoother is additionally used.

Before applying the aftertreatment agent through the aftertreatment machine, the blanket must still be given a final surface finish having a surface texture corresponding to the intended use. This is to increase the grip and ride comfort, and reduce the tire-road noise.

The concrete surface must be protected against drying out immediately after manufacture. The spraying of a post-treatment agent is customary.

With regard to the texturing of the concrete surfaces, the clients have different requirements with regard to the type of texture to be applied.

As a result, it may be necessary for the aftertreatment machines to be converted in a time-consuming manner in order to achieve a desired texturing as desired by the client. Another disadvantage is that the conversion kits must be kept separately.

The same applies to the spraying of the aftertreatment agent.

A further disadvantage is that after the conversion of the machines, the texturing devices are usually positioned in front of or behind the machine frame, whereby the pitching or tilting movements of the machine frame about a substantially ground-parallel axis transverse to the working direction due to the inertia and inertia during start-up and braking of the aftertreatment be strengthened the suspension of the machine frame via lifting columns. This is particularly disadvantageous because the texturing tools thereby change their engagement height relative to the concrete surface and therefore texturing takes place in the acceleration and deceleration phases at different heights.

The invention is therefore an object of the invention to provide a post-treatment machine and a method for subsequent processing of freshly made concrete layers that can perform different texturing and / or spraying tasks without time-consuming changeover times in a simple manner.

To solve this problem serve the features of claim 1 and 13, respectively.

The invention advantageously provides that the working devices for applying either texturing or aftertreatment means have both a workstation acting in the longitudinal direction in operation and a working device that can be moved back and forth over the width of the concrete layer, which are mutually reciprocally movable from a rest position into an operating position can be transferred, in which the working facilities do not collide with each other. In this way, it is possible to provide both in the longitudinal direction of the concrete layer acting as well as acting in the transverse direction of the concrete layer working equipment, each serving the same purpose, namely either for applying a texturing or for applying a post-treatment agent. They are alternatively convertible to a rest position so that they can not collide with the alternative work equipment for the same use and also not with the work equipment for another use.

Accordingly, depending on the service order, the aftertreatment machine can be retrofitted in a very short time, so that flexibly any combination can be carried out with respect to the application of a post-treatment agent in the longitudinal or transverse direction of the concrete layer and the application of texturing in transverse or longitudinal direction.

The working devices for applying either a texturing or a post-treatment agent can each be fixed to the machine frame in a stationary manner as well as transversely to the working direction.

Preferably, it is provided that the stationary during operation work device is pivotally mounted from an operating position to a rest position on the machine frame such that the movable working collision-free relative to the resting in the working position or under the working position in rest position collision freely reciprocated ,

A working device that can be moved to apply a texturing can be a cross texturing device, which can be moved to a rest position in which the cross texturing device is out of engagement with the concrete layer.

In particular, the invention advantageously provides that the working devices have both a longitudinal texturing device and a transverse texturing device that can be moved back and forth across the width of the concrete layer. Both texturing devices can be mutually transferred from a rest position to a working position, wherein in both cases the texturing devices do not collide with one another.

In this way, it is possible either to bring the longitudinal texturing device or the transverse texturing device into their respective rest position and to perform the texturing with the respective other texturing device, without requiring long changeover times.

It is preferably provided that the longitudinal texturing device is fastened from an operating position to a rest position pivotably on the machine frame such that the cross texturing device can be moved back and forth under the longitudinal texturing device located in the rest position. Here, the Längstexturiereinrichtung is pivoted upwards in a rest position, so that the Quertexturiereinrichtung can be moved without collision over the width of the road surface. The conversion of the aftertreatment machine to the other mode of operation can be done in no time.

The movable working device, in particular the cross texturing device, can be moved into a rest position in which the working device is out of engagement with the concrete layer. Thus, the cross-texturing device is located outside the width of the road surface, so that it can not collide with another working device, in particular a longitudinal texturing device in the downwardly pivoted position.

The cross-texturing device is preferably movable back and forth on a rail guide transversely to the working direction, which has a height offset on at least one lateral end beyond the width of the concrete layer, which the Quertexturiereinrichtung at this end in the rest position raises. In the raised position, it is ensured that the cross texturing device does not come into contact with either the concrete layer or the longitudinal texturing device.

In a preferred embodiment, it is provided that the machine frame has parallel to the working direction extending longitudinal beams and transverse to the direction of the cross member, wherein the transversely extending to the direction of the cross member for variable adjustment of the track width of the drives and to adapt to the width of the concrete layer are telescopic.

It is preferably provided that the working devices have a longitudinal spraying device and / or a transverse spraying device which can be moved back and forth over the working width of the concrete carriageway.

The machine may therefore comprise a longitudinal sprayer or a cross sprayer, or both sprayers.

In particular, it can be provided that the spraying device has a longitudinal spraying device which is stationary during operation and / or a transverse spraying device which can be moved back and forth over the working width of the concrete layer, wherein the longitudinal spraying device is pivotably secured to the machine frame from an operating position into a rest position serving as a transporting position.

The pivoting of the longitudinal spray device, which extends across the width of the machine, on the one hand serves to keep the machine width narrow for the transport case, so that the machine can be transported on 90 ° rotated drives on a special transport vehicle on roads.

On the other hand, the pivoting of the longitudinal spraying device serves to enable the transverse spraying device to be moved over the width of the machine without collision.

It can be provided that the cross-spray device in the operating position in extension of the cross-texturing device preferably in the working direction lagging or arranged on one side or on both sides next to the Quertexturiereinrichtung and is movable together with the Quertexturiereinrichtung.

Preferably, it is provided that the transverse and longitudinal texturing means are arranged in the working direction at the height of laterally arranged on the machine frame drives or between front and rear drives.

The machine frame can be carried by two individual laterally arranged longer drives, or by a total of four drives, wherein two consecutive drives can be arranged on each side of the machine frame. The drives are connected via lifting columns with the machine frame over which a height adjustment of the machine frame can be made relative to the ground. It is essential that the transverse and Längstextureereinrichtungen are arranged substantially centrally of the individual drives arranged on both sides or between the respective front and rear drives. This has the advantage that the texturing tools experience only a small change in height when starting or braking the machine. The resulting pitching movements of the tools during start-up or braking are thereby minimized.

The transverse and / or longitudinal texturing means are preferably positioned in the machine frame such that their mass distribution in the working direction relative to the center of the lateral drives or the center between the front and rear drives is balanced such that only a small moment of inertia is applied to the acceleration during acceleration or deceleration Machine frame acts.

It is preferably provided that the transverse and Längstexturiereinrichtungen have tools that are attached to a quick-change system. In this way it is possible to replace the tools without long set-up times, or replace defective tools without significant loss of time.

The spraying devices preferably have spray nozzles that can be selected via a quick-change device, so that in a simple way the Spray behavior of the spraying changed, or a defective or clogged nozzle can be replaced by another.

Furthermore, it is possible, via a simple attachment of the spray nozzles, z. B. along a rail to adjust the mutual distance.

The invention advantageously provides, according to a method for the subsequent processing of freshly produced concrete layers, that a working device stationary in operation and a working device reciprocating across the width of the concrete layer can alternatively be used to apply either a texturing or a post-treatment agent by the Working devices are each mutually transferred when not in use from an operating position to rest positions in which they do not collide with each other.

In the following, embodiments of the invention will be explained in more detail with reference to the drawings.

Fig. 1 shows a post-treatment machine 1 in the form of a brush spraying machine as shown in the EP 1 841 637 A is known. The aftertreatment machine 1 may be a newly manufactured concrete layer 10, z. B. a road surface by means of a Quertexturiereinrichtung 3, z. B. a brushing unit, texturizing and spray with the aid of a spray unit 6 then with a liquid post-treatment agent.

The machine frame 2 has a suitable depth for transport on a transport vehicle, so that the machine can be transported on the transport vehicle on a road to the place of use. The machine frame has in comparison to the depth of a multiple of the width, for example, widening elements are used to adapt to a certain roadway width or the machine frame 2 is telescopic. It can be in the in Fig. 1 shown working position a roadway width of, for example, be bridged up to 18 m. The working direction is indicated in the respective drawings by an arrow 50.

The machine frame 2 has parallel to the working direction 50 extending side members 28 and transversely to the direction 50 extending cross member 18, wherein the transverse to the direction of the cross member 18 for variable adjustment of the track width of the drives and to adapt to the width of the concrete layer 10 are telescopic.

The aftertreatment machine 1 has a chassis with multiple wheels and / or crawler tracks 4, which carry the machine frame 2 via lifting columns 8 adjustable in height.

The use of a total of four drives 4 at the lateral ends of the aftertreatment machine 1 has the advantage of greater stability, the arrangement of the working facilities, in particular the texturing means 3,5 in the direction of travel 50 centrally between the drives 4 has the advantage that the influence of inertia forces be minimized to the machine frame 2 when starting or deceleration of the aftertreatment machine 1. In addition, however, slight pitching movements taking place still have less of an effect on the position of the texturing device relative to the concrete surface.

The wheels or crawler tracks 4 can in particular in the case of four crawler tracks 4 of a in Fig. 1 shown working position are transferred to a transport position by means of a swivel gear. In the working position, as in Fig. 1 In the transport position, the chain drives 4 extend parallel to the longitudinal extent of the machine frame 2, that is, pivoted by 90 ° and transversely to the longitudinal members 28th

The crawler tracks 4 are hydraulically driven, steerable and height adjustable.

Fig. 2 shows a perspective view of the aftertreatment machine 1. On the left in the direction of travel 50 is the drive unit 22 with a control panel 24. Both are arranged on a platform 20 of the machine frame 2, which is walkable and on your the drive unit 22 opposite side of a spray tank 26th having.

As in the prior art, the transverse spraying device 6 is fastened to a transversal drive transversely across the concrete layer 10 or the carriageway width. Furthermore, at the transverse drive the Quertexturiereinrichtung 3, z. B. from a brushing unit attached. The cross texturing device 3 is, as on best Fig. 3a can be seen, with a rail-guided provided with a transverse drive carriage 12 over the width of the concrete layer 10.

The Quersprühererichtung 6, as shown in the Fig. 2 is shown, is detachably attached to the transverse drive. It can therefore be solved by switching to a Längssprühererichtung 7 of the transverse drive.

Alternatively, the transverse spraying device 6 may also be fastened to the transverse texturizing device 3, it also being possible for two spraying devices 6 to be arranged transversely to the concrete layer 10 or roadway in front of and behind the transverse texturing device 3 in the direction of movement of the transverse texturing device 3.

Fig. 3a shows the cross texturing device 3 in the activated state in the working position while the longitudinal texturing device 5 is in a rest position in which it does not collide with the cross texturing device 3 or its slide 12.

The transverse and Längstexturiereinrichtungen 3, 5 have a quick-change device for tools, so that in a short time different brushes or tools, eg. As steel tines or plastic brushes can be used.

In the embodiment of the Fig. 3a the Quertexturiereinrichtung is combined in working position with a Längssprühererichtung 7 in working position. The Längssprüheinrichtung 7 can also be pivoted by means of a piston-cylinder unit 9 in a rest position, in Fig. 2 it can be seen in which the longitudinal spray device 7 can not collide with the transverse spray 6. At the same time, the rest position of the longitudinal spraying device 7 can also be used for transport, since in this position the total depth of the machine still makes it possible to transport it on a low loader.

In Fig. 3a the side part of the windscreen 11 is removed to release the view of the nozzle assembly 14 and its holder 16.

The longitudinal spraying device 7 is height-adjustable, for example, by an amount of approximately ± 150 mm. Spray nozzles 14 are located at the lower end of a holder 16. Preferably, a turret for different spray nozzles is arranged at each spray nozzle position, so that the Längssprüheinrichtung (as in the case of a cross spray 6) are quickly adjusted to a different nozzle type or a defective or clogged nozzle another can be replaced.

Fig. 3b shows the combination of the cross texturing device 3 with a cross spray 6, wherein the Längstextureerrichtungen 5 and the longitudinal spray 7 are in rest position.

Fig. 4 shows a perspective view of the machine with activated Längssprüheinrichtung 7 in working position, which is surrounded by a windbreak 11.

Fig. 5 shows a side view of the aftertreatment machine 1 according to the embodiment of Fig. 4 , In this combination, the longitudinal texturing device 5 and the longitudinal spraying device 7 are in the working position, while the transverse texturing device 3 is not visible in a raised rest position at one of the lateral ends of the aftertreatment machine 1.

The rail guide of the carriage 12 is raised for this purpose in an area laterally adjacent to the concrete layer 10 by a predetermined amount, so that the Quertexturiereinrichtung 3 can be transferred to a raised state next to the concrete layer 10 or roadway in a rest position. In this rest position of the cross texturing device 3, the longitudinal texturing device 5 can be pivoted in its working position without it colliding with the transverse texturing device 3.

The longitudinal texturing device 5 can by means of piston-cylinder units 13 from the working position in the example in Fig. 3a and 3b shown resting position and vice versa.

It is understood that any combination of working in the longitudinal or in the transverse direction working devices 3, 5, 6, 7 is possible.

The FIGS. 6a to 6c show a rail guide 48, which makes it possible to raise the Quertexturi 3 by means of a roller guide 52 outside the concrete layer 10 in a rest position, preferably only the Quertexturiereinrichtung 3 is raised.
