Description

Process and Device for Supporting and Displacing a Semimobile Crusher Plant This application claims priority from German Application No. 10 2013 202 071.6 filed on 8 February 2013, the contents of which are to be taken as incorporated herein by this reference. The present invention pertains to a process for supporting and displacing a semimobile crusher plant as well as to a semimobile crusher plant. Crusher plants known from the state of the art are usually used in a stationary manner and are only mobile insofar as they can be passively displaced. Such a crusher unit of a portable crusher plant is known from DE 37 36 966 C2. The crusher unit here has a portal-like frame, which is supported via pontoons on a load-bearing natural ground or via support feet on concrete foundations. The crusher unit cannot be actively transported, but can be relocated by means of suitable apparatus, e.g., a transport caterpillar. Such a transport caterpillar is described in the printed publication DE 296 23 367 UI. For displacing a crusher plant, the caterpillar with its two-caterpillar-type chassis is driven under the portal and its elevating platform is connected to the portal. The crusher plant is elevated via a suitable hydraulic system arranged at the caterpillar and transported in this position. Because of the high weight of up to 2,000 t of usual crusher plants, these must always be kept in a horizontal position when traveling on a level surface but also on inclines in order to load the transport caterpillar centrally and to rule out a tipping over of the crusher plant with a high center of 1 gravity. If the new location is reached, the crusher plant is set down and the transport caterpillar is driven away. Because of the great weight of crusher plants caterpillars suitable for their transport are complicated and expensive. Therefore, they are preferably leased and supplied each time for displacing a crusher plant. In addition, the transport of the crusher makes it necessary to remove the dischargers arranged separately in the portal. For reasons of weight, other components are also frequently removed and transported separately. This manner of displacing is complicated and takes up several days, which results in a high loss of production during the crushing of excavated material. The obj ect of the present invention is to overcome the drawbacks of the state of the art and suggest a crusher plant, which can be relocated in a short time and nevertheless has a high operating safety during crushing. During displacing, the entire crusher plant shall be able to be transported safely without major disassemblies even over open pit mining ramps. This object is accomplished by a semimobile crusher plant according to the main claim as well as a process for supporting and displacing this crusher plant according to claim 7. Variants of the present invention are preferably the subjects of the related subclaims. According to the present invention, the object is accomplished by a crusher plant, to whose lower supporting structure both caterpillar-type chassis and support rockers are permanently fastened, 2) whereby the load of the crusher plant is completely borne by the caterpillar-type chassis when relocating. At the operating site, the load of the crusher plant, including a najor payload, is borne more or less equally by the caterpillars as well as the support rockers. The semimobile crusher plant according to the present invention has a supporting frame, in which are arranged a receiving bunker for material dumped by trucks, a crusher, an intermediate bunker for the crushed material as well as a discharge belt. A caterpillar-type chassis consisting of three double caterpillars is permanently arranged under the supporting frame. In a preferred embodiment of the present invention, the six-caterpillar-type chassis consists of two rear double caterpillars that are mounted at the supporting frame in a noncontrollable manner, as well as a front, controllable double caterpillar. The single caterpillars are connected to one another by pendulum axles and carrying cases, whereby the pendulum axles make possible a transverse pendular motion of the caterpillars to one another as well as to the lower supporting structure. The carrying cases are connected via longitudinal axles to the support rockers, which are fastened via major axles to the supporting frame of the crusher plant. In this case, the pendulum axles and the longitudinal axles in pairs form cross joints. The rockers, which are preferably mounted rotatably by means of axles, support the entire load of the crusher plant in a first position via the cross joints on the pairs of caterpillars. In this first position, the support rockers lie against a stop, as a result of which the rotatability is blocked. A movement of the support rockers with a weight displacement connected therewith is consequently eliminated.

On the other hand, during a crusher operation, the support rockers are mounted rotatably about the axles. Consequently, half of the load is set down onto the caterpillars and half of the load is set down on specially shaped foundation blocks [sic, obvious typo for "Fundamentblocke" - this occurs repeatedly -Tr.Ed.I. The support feet of the support rockers here have sloping surfaces directed downwards and provided with flanges. These bring about a rotary movement of the support rockers about the major axles from the first into the second position during the sliding on sloping surfaces, directed upwards, of the foundations arranged at the respective operating sites. Furthermore, the subject of the present invention is a process for displacing and supporting a semimobile crusher plant. Here, the crusher plant is borne completely by the caterpillar-type chassis during the displacing. The support rockers of the crusher plant lie against the underside of the supporting frame during the displacing and support the entire load of the crusher plant via cross joints on the caterpillar-type chassis. Foundations, which correspond in their arrangement and size with the double caterpillars as well as support rockers located at the supporting frame of the crusher plant, are provided at the operating positions of the crusher plant. The foundations have, in the direction of approach of the crusher plant, surfaces that are rising diagonally and are provided with flanges. During the descending of the crusher plant, the sloping support surfaces of the support feet arranged at the support rockers slide onto the sloping foundation blocks [sic - Tr.Ed.]. Due to a slight rotation of the support rockers brought about thereby, up to 50% of the load of the crusher 4 plant is supported on concrete foundations. If the support rockers have reached their end position, the crusher plant is preferably connected to the flanges of the foundations via the flanges arranged at the support feet and thus further increases the operating safety. The object according to the present invention is thus accomplished by the crusher plant being displaced via three double caterpillars, and the additional support at the operating site taking place via rockers, whose one side places the load in each case onto the set of caterpillars and whose other side places the load in each case via support feet onto the concrete foundation. The crusher plant is supported only on the caterpillar-type chassis during the displacing and partly on the caterpillar-type chassis and partly on support feet during the crusher operation. To avoid large and complicated hydraulic cylinders, the rockers are designed, such that they guide the entire load onto the sets of caterpillars during the displacing of the crusher plant and slide, during the descending into the operating position, only by the traveling motion, on the side opposite the caterpillars onto the sloping surfaces of trestles, which are embedded in concrete foundations. Exemplary Embodiment Further details and advantages of the present invention are explained below based on an exemplary embodiment as well as the attached drawings. In the drawings, Figure I shows a schematically shown six-caterpillar-type chassis of a semimobile crusher plant, 5 including the support walls for two truck ramps in a top view, and Figure 2 shows the caterpillar-type chassis of the semimobile crusher plant according to Figure 1 with the lower supporting structure in a side view. For the feeding of material to be crushed by means of trucks the semimobile crusher plant in Figure 1 is in operating position in a notch, whose walls are predetermined by the receiving bunker and the two truck ramps 1, 2. Since it is advantageous for the stability of the approx. 20 m high walls that the truck ramps 1, 2 form an angle of 60' against each other, a trapezoidal notch forms, into which a six-caterpillar-type chassis with a three-point support is optimally inserted. This chassis has a great support distance and does not require any leveling even during traveling. It leaves the center under the crusher free for the discharge belt 21 with receiving hopper and has a high load capacity, such that no components have to be removed during the displacing of the crusher plant. The six-caterpillar-type chassis consists of two rear, noncontrollable double caterpillars 4, 5 and a front double caterpillar 3 controllable via a pair of cylinders, not shown in the drawing. The double caterpillars 3, 4 and 5 are also designated below as pairs of caterpillars 3, 4 and 5. Because of the caterpillar control, the chain mechanisms and driving powers are small, such that standard gears, known for the drives of construction machines, can be used. Each single caterpillar of the pairs of caterpillars 3, 4 and 5 has two four-wheel bogies and four two-wheel bogies, which uniformly distribute the load on eight bogie wheels. The single 6 caterpillars shown in Figure 2 are each connected to each other by means of pendulum axles 6, 7 and 8 as well as carrying cases 9, 10 and 11. Here, the pendulum axles 6, 7 and 8 make possible an independent transverse pendular movement of the single caterpillars against one another and opposite the lower supporting structure 28. The carrying cases 9, 10 and 11 are in turn connected to the support rockers 15, 16 and 17 via longitudinal axles 12, 13 and 14. This brings about an equal load distribution onto both caterpillars of a pair of caterpillars 3, 4 and 5. The pendulum axles 6, 7 and 8 and longitudinal axles 12, 13 and 14 form cross joints in pairs and make possible an independent transverse pendular movement against one another and opposite the lower supporting structure 28. The support rockers 15, 16 and 17 are connected via major axles 18, 19 and 20 to the front pivoting frame 29 or the lower supporting structure 28. During the crusher operation, up to approx. 50% of the support loads are distributed onto the double caterpillars 3, 4 and 5 on one side as well as up to approx. 50% onto the support feet 22, 23 and 24 on the other side. The support of the support feet 22, 23 and 24 takes place via sloping surfaces with flanges, which rest on the foundation blocks [sic - Tr.Ed.] 25, 26 and 27, which are also provided with flanges, and are bolted to same. The support surfaces 30, 31 and 32 on the foundation blocks [sic - Tr.Ed.] 25, 26 and 27 are shown in Figure 1 as a top view. The bolted connections are detached for displacing the mobile crusher plant. The crusher plant then backs up slowly, whereby the support feet 22, 23 and 24 are lowered and the support rockers 15, 16 and 17 are rotated. After a small rotation, the support 7 rockers 15, 16 and 1 7 come to a stop on opposite sides. The entire load is now borne by the pairs of caterpillars 3, 4 and 5. When traveling into the new position, the sloping support surfaces 30, 31 and 32 opposite the double caterpillars of the pairs of caterpillars 3, 4 and 5 slide onto the sloping foundation blocks [sic - Tr.Ed.] 25, 26 and 27. The stops of the support rockers 15, 16 and 1 7 are raised and again up to approx. 50% of the load lies on the foundation blocks 25, 26 and 27. The flanges are bolted to one another for the duration of the crusher operation. 8 List of Reference Numbers I Truck ramp 2 Truck ramp 3 Pair of caterpillars 4 Pair of caterpillars 5 Pair of caterpillars 6 Pendulum axle 7 Pendulum axle 8 Pendulum axle 9 Carrying case 10 Carrying case 11 Carrying case 12 Longitudinal axle 13 Longitudinal axle 14 Longitudinal axle 15 Support rocker 16 Support rocker 17 Support rocker 18 Major axle 20 Major axle 21 Major axle 9 21 Discharge belt 22 Support foot 23 Support foot 24 Support foot 25 Foundation block 26 Foundation block 27 Foundation block 28 Lower supporting structure 29 Pivoting frame 30 Support surface 31 Support surface 32 Support surface 10
