Definitions
- EP 329 915 A also describes an eccentrically activated system only one eccentric and tool for slitting the hardest materials.
- the new device claimed below in the multiple eccentric with several Tool sleeves work, the entire unit runs much smoother, reduced the necessary pressures considerably and offers the possibility of any drilling respectively Machinable milling widths - only hitting or hitting milling.
- the invention Method works using the device according to the invention. Through this Technology according to the invention are also storage problems due to excessive weight and amplitude dependent centrifugal forces eliminated.
- a one-sided double eccentric shaft with two sleeves and milling tools comes with 3,000 RPM driven; the amplitude is 5 mm.
- About the reduction gear Tool sleeve 30: 1 driven at 100 rpm; Tool sleeve width and diameter: 250 mm x 2 500 mm drilling width with a required pressure of approx. 1 ton in hard rock and approx. 10 kw drive power.
- Conventional systems require several.
- FIG. 1 each with only one possible embodiment, one of the holders is shown in FIG. 1 (1), (2) one of the sleeves rotatably mounted on an eccentric. (3) is a reduction gear via one External and internal gear rim. Tools are indicated with (4). (5) are the for Balancing necessary counterweights. (6) drives the high-speed eccentric shaft, (7) a disc-type roller drilling tool. (8) are seals, and (9) is a version for Compacting soil and the like using the sleeve as a roller or using a plate (without Rotary drive for the tool sleeve). The actual tools are interchangeable. The sleeve and the tools are weighed / balanced on the counterweights (5).
- (10) is the gear drive via the held inner shaft (11) for the outer sleeve (12).
- the second inner sleeve (13), which is also rotatably mounted on the eccentric (14), is (15) driven slowly rotating.
- the double eccentric shaft is driven by (16) at high speed; the bracket for the unit is (18).
- the weights on which the respective sleeve and tools are balanced, are designated with (19) and attached to / on the eccentric shaft.
- a double eccentric with a central holder, (20) is one of the two tool sleeves with their drive (21). To remove any web that may have stopped, they are set back Picking or the like (22) provided. (23) is the second sleeve for tools and the Counterweight (24).
- the eccentric shaft with two staggered or at the same time beating eccentric is (25).
- an eccentric rotatable sleeve for varying the Amplitude, separate protection is claimed. It is preferably with a toothing on the Shaft (27) pushed and fixed on it.
- (28) is the central holder with e.g. a toothed belt (29) as a drive for the shaft (27).
- the center line drawn means that with this aggregate this axis rotated also pilot / full holes can be created.
- (30) are the sleeves and tools of the same length and weight, each of which has (31) driven slowly rotating and balanced / balanced against (32).
- This too The system can work as a striking roller drilling tool, without - but also with the drive Tool sleeve.
- additional holders and tools (33) are the two holders with the drive (34) via toothed belts in this version.
- two sleeves are preferably each in the Brackets mounted and driven (only hatched).
- a special design without counterweights according to (32) in Figure 4, (35) are the two outer, equally wide and heavy tool sleeves. (36) is opposite one of the outer ones Balancing sleeves required double wide and heavy tool sleeve. This works this system is optimally balanced without any separate counterweights. (37) are the 180 ° offset eccentric on which the sleeves (35) and (36) are rotatably mounted. You can / do not have to be driven via the gear pairs (38). The holders can too be arranged outside; for this purpose drivers are then provided between the tool sleeves.
