1. A support device for conveying heavy loads, comprising: a support body anda roller body which revolves around the support body,wherein the roller body comprises a series of support rollers and distancing rollers,wherein the distancing rollers have a smaller diameter than the support rollers, and the distancing rollers in each case space consecutive support rollers from one another,wherein the support device is provided for supporting a load which moves along a support region, and the roller body, at least in the support region, is covered over its whole width by a belt, and thus the support rollers roll on the support body and on the belt, in the support region, andwherein in each case two distancing rollers are arranged between two consecutive support rollers. 2. A support device according to claim 1, wherein pivots of the support rollers define a reference surface, in which they move, and pivots of an outer group of distancing rollers run outside the reference surface, and pivots of an inner group of distancing rollers run within the reference surface. 3. A support device according to claim 1, wherein in each case two distancing rollers are rotatably mounted on at least one co-moved bearing element. 4. A support device according to claim 3, wherein apart from the in each case two distancing rollers, a support roller is also movably fastened in each case on the at least one co-moved bearing element, and these rollers together form a roller unit. 5. A support device according to claim 1, in which in each case a holding belt wraps around two distancing rollers which are assigned to one another, or around pivots of these distancing rollers. 6. A support device according to claim 4, wherein, in the case that the support roller and a lower distancing roller of a roller unit both lie on a support surface, the rotation axis of an upper distancing roller lies above a plane which runs through the rotation axis of the support roller and parallel to the support surface. 7. A support device according to claim 6, wherein the distancing rollers slip or tilt against the support surface when two support rollers or roller units are pulled apart, and the distancing rollers are lifted up or set up again when the roller units collide. 8. A support device according to claim 4, wherein in a roller unit, the support roller comprises at least three coaxial sections, which are connected to one another via a roller pivot, a bearing element is rotatably arranged on the roller pivot, in each case between two of these sections, and the two distancing rollers are mounted between the two bearing elements. 9. A support device according to claim 1, wherein the support body comprises two peripheral guide grooves, and the support rollers are guided in the guide grooves by way of pivot stubs, and the distancing rollers are guided in the guide grooves or in further guide grooves by way of pivot stubs. 10. A support device according to claim 9, wherein the support rollers or the distancing rollers are mounted in the guide grooves by way of roller bearings or by way of sliding bearings. 11. A support device according to claim 1, wherein in each case exactly one distancing roller is arranged between two consecutive support rollers. 12. A support device according to claim 1, wherein a shoulder of a bearing element or of a bearing projects in the radial direction into an enveloping cylinder of the support roller and by way of this limits a movement of the support roller along the direction of its roller axis. 13. A conveying device with two or more support devices according to claim 1, wherein the support devices are arranged in series behind one another, and an intermediate element with at least one movable support element, in particular with an intermediate roller, is arranged between the support devices and wherein the support devices and the intermediate element can be strung together with a positive fit. 14. A conveyor device according to claim 13, wherein support devices and intermediate elements form a modular construction system, with which support devices and intermediate elements may be strung together in an infinite number, for forming the conveyor device. 15. A conveyor device according to claim 13, wherein the intermediate elements are integrated into the support devices, and the support devices with the integrated intermediate elements may be strung together, preferably with a positive fit. 16. A conveyor device according to claim 13, wherein several rows, in each case with several support devices and intermediate elements, are arranged parallel to one another, in the conveyor device. 17. A conveyor device according to claim 13, wherein the conveyor device is inclined at least in sections. 18. A support device for conveying heavy loads, comprising: a support body anda roller body which revolves around the support body,wherein the roller body comprises a series of support rollers and distancing rollers,wherein the distancing rollers have a smaller diameter than the support rollers, and the distancing rollers in each case space consecutive support rollers from one another,wherein the support device is provided for supporting a load which moves along a support region, and thus the support rollers roll on the support body, in the support region, andwherein in each case two distancing rollers are arranged between two consecutive support rollers. 19. A support device for conveying heavy loads, comprising: a support body anda roller body which revolves around the support body,wherein the roller body comprises a series of support rollers and distancing rollers,wherein the distancing rollers have a smaller diameter than the support rollers, and the distancing rollers in each case space consecutive support rollers from one another,wherein the support device is provided for supporting a load which moves along a support region, and the roller body, at least in the support region, is covered over its whole width by a belt, and thus the support rollers roll on the support body and on the belt, in the support region, andwherein the support devices are arranged in series behind one another, and an intermediate element with at least one movable support element, in particular with an intermediate roller, is arranged between the support devices and wherein the support devices and the intermediate element are strung together with a positive fit.
