Device for distributing shotcrete and the like

The invention relates to a device for distributing shotcrete and the like with a chassis and a platform that can be raised and lowered and supported on parallelogram links, which carries a turntable for a console, on which a pivotable about a horizontal axis, possibly telescopically extendable Boom is mounted, which carries at its free end a pendulum-movable spray nozzle about the axis of the boom.

Such devices are used, among other things, in underground mining or also used in tunnel construction, for example when shotcrete is distributed over an area, for example an extension target.

In a known device, the platform is parallel over two Handlebar supported on the chassis of a truck. The pivot axes of the parallel links are on the platform as well arranged on the chassis in horizontal planes. The platform has a relatively great length and one at the top Rail arrangement for the turntable with console, so that the console and thus the boom can be moved along the platform. The boom connected to the console can be swiveled through almost 360 degrees together with the console, but it remains with the Raising the platform and always tied to the longitudinal axis of the chassis when moving along the platform.

The object of the invention is, in a device of the type described at the outset, the mobility of the spray nozzle with different

to improve reduced construction effort.

This object is achieved in that the pivot axes of the parallel links are on the one hand in vertical planes one above the other are arranged on the platform and on the other hand on a pivot bearing with a vertical pivot axis of the chassis.

In the device according to the invention, the platform only needs to have a length that is sufficient to accommodate the turntable. Therefore, the device can also be mounted on relatively short running gears, for example on crawler tracks, as they are used in underground mining and tunneling. Such undercarriages are actually more agile than a Trucks, however, in the device according to the invention, the mobility of the spray nozzle is improved in that the platform is not only raised via the parallel links but also swiveled out of the longitudinal axis of the chassis with the parallel links can be. The design effort for pivot bearings is generally less than the design effort for a longer platform equipped with a rail arrangement.

In particular, the pivot bearing can be a vertical one on the chassis Axle have pivotably mounted bearing bolts with connection device for the parallelogram link. The bearing pin is expediently stored on both sides, for which purpose it has pins at both ends that engage in associated bearing bores on the chassis. Such bearing bores or associated consoles can also be used with crawler tracks and the like without difficulty accommodate.

With regard to the stability of the chassis, one is recommended

Arrangement in which the bearing pin can pivot about its axis to a limited extent is. In particular, the pivot angle of the bearing pin should be 30 degrees with respect to the longitudinal axis of the chassis.

In order to allow easy adjustment of the pivoting angle of the bearing pin and thus of the platform relative to the longitudinal axis of the vehicle, kaan the bearing pin have a swivel drive. In a preferred embodiment of the invention, the Swivel drive on at least one lifting cylinder on the one hand on the chassis and on the other hand on a cantilever arm of the bearing pin is supported.

The mobility of the spray nozzle can also be improved if the spray nozzle is also about the axis of the boom is pivotable about a substantially horizontal axis which is orthogonal to the axis of the boom. The spray nozzle can be attached to a Be mounted console that is pivotable about the horizontal axis at the end of the boom and with a lifting cylinder on the boom is supported. Then namely the spray nozzle can also reach surfaces or surface sections that are seen from the spray nozzle are in the direction of the landing gear.

In general, it is sufficient if the console can be pivoted to a limited extent about the horizontal axis, in particular by an angle from approx. - 90 degrees

In the following an embodiment of the invention shown in the drawing will be explained; it shows the only figure in schematic representation of a side view of a device for distributing shotcrete.

The device shown initially includes a chassis 1,

which is a crawler track in the embodiment. This landing gear 1 has drives, not shown, which are partly in a box 2 connected to the chassis and partly in further Superstructures 3 are housed. The box 2 sits at one end of the chassis 1 on the side facing the center of the chassis 1 of the box 1, a U-shaped profile 4 is attached, the U-legs, of which only one U-leg 5 is visible, bearing ■ bores for pins 6 which are arranged on both sides at the ends of a bearing pin 7. The bearing pin 7 has a Connection device 8 for parallel links 9, OK, their pivot axes 11, 12 in a vertical plane one above the other on the bearing pin 7 or the connection device 8 are arranged. The piston rod 12 engages the connecting device 8 in an articulated manner on at least one side a lifting cylinder 13 which is held on the outside of the box 2 in a pivot bearing 14.

The upper parallel link 9 is on the chassis via a lifting cylinder 15 of the chassis 1 supported. The other two ends of the parallel links 9, 10 are connected to a connection device 16 of a platform 17 connected. On this side, too, the pivot axes 18, 19 of the parallel links 9, 10 are one above the other in a vertical plane arranged.

The platform 17 carries a turntable 20, the rotatable part of which is connected to a bracket 21, which in the illustrated embodiment is designed as a cabin 22. On the front side of the console 21 or the cabin 22 is pivotable about a horizontal axis 23 a boom 24 is mounted, which is supported on the bracket 21 via a lifting cylinder 25. The boom 24 consists of two telescopic parts which can be moved apart, the extendable part 26 moving in and out with the aid of a lifting cylinder 27 attached to the boom 24 is extendable.

The part 26 carries at its free end a pivot bearing 28 with an axis of rotation parallel to the boom axis. To the rotatable part 29 of the Pivot bearing 28 is connected to a pivotable bracket 30, the pivot axis 31 of which in the puncture position shown in FIG runs essentially horizontally. In addition, the pivot axis 31 extends orthogonally to the axis of rotation of the rotating part 29 and thus to the Cantilever axis. The console 30, which is supported by a lifting cylinder (not shown) on the rotating part 29, carries on its front End of a spray nozzle 32 which is connected via a hose 33 to a concrete pump, not shown. The axis of the spray nozzle 32 extends in the illustrated embodiment orthogonally to the axis of the rotating part 29 and thus to the boom axis.

It goes without saying that the various drives from the car 22 are controllable from. Corresponding control devices and hydraulic hoses or the like are not shown.

The drawing shows the device in the rest position, in which the two parallel links are arranged essentially horizontally one above the other and the platform 17 has reached its lowest position. The boom 24 is retracted. During operation, the following options exist to bring the spray nozzle 32 into position. First, the spray nozzle can be brought into the position shown on the right in the figure or into an intermediate position by actuating the lifting cylinder 27 and telescopically extending the part 26. The spray nozzle 32 may further by means of the drive of console 30 by an angle of about - 90 degrees i ⁿ the vertical are pivoted. By rotating the rotatable part 29 in the pivot bearing 28, the spray nozzle can also oscillate in a range of about -90 degrees around the out-of-the-way drive.
