Definitions
- the invention relates to a supporting device for a jacking or mining machine with supporting punches and at least one ridge cap.
- An articulated support device with integrated anchor drilling and setting device can be found in AT 392116 B.
- a support frame is connected to the frame of the tunneling machine via arms extending in the machine longitudinal direction.
- the invention now aims to provide a supporting device for a propulsion and mining machine, which is characterized by a particularly efficient temporary support of the roof, without this being the work of anchor drilling and setting facilities is excessively limited. At the same time with such an enlarged temporary support, the stability of the tunneling machine should also be ensured for large burglary forces and an improved protection for the respective operators ensured.
- the supporting device consists essentially in that the ridge cap (s) on its side facing away from the support stamps have a plurality of support cylinders with support stops, which are separately braced against the ridges. Due to the fact that the ridge caps have a plurality of support cylinders with support stops on their side facing the roofs or facing the support posts, which can be braced separately against the roofs, it can be ensured that a permanent contact of all contact elements of the support device to the roof is provided. In this way, the safety regulations for underground work can be met while the respective support force distributed over a plurality of contact points over a larger area in a correspondingly gentle manner be introduced into the mountains. An excessive contact pressure in partial areas can be safely avoided in this way.
- the training is in this case made such that a ridge cap cooperates transversely to the machine longitudinal direction of the propulsion or mining machine with at least two off-center supporting dies, preferably the ridge cap is U-shaped in plan and in the region of the free ends of the U- Leg and at the top in the plan view of the defined by the points of attack of the support stamp on the ridge cap pivot axis of the ridge cap opposite side of the ridge cap each support cylinder are arranged.
- the particularly advantageous embodiment of the ridge cap as in the plan U-shaped plate, in which in the region of the free ends of the U-legs support punches are arranged, allows about this arranged at the free ends of the U-legs support punch correspondingly reduced support forces in the ridges bring in, whereas the lying on the other side of the previously defined pivot axis, arranged on a shorter lever arm support stamp in the machine itself can transmit much larger forces.
- the U-shaped floor plan makes it possible to ensure a free space between the free legs, over which anchor drilling and setting devices can be used in the desired manner without hindrance.
- the training is in this case made such that the distance of the machine front end facing support cylinder from the pivot axis defined by the support shaft 2 to 7 times, preferably 3 to 5 times the distance between the support cylinder to the other side of the pivot axis of the pivot axis , In principle, the support cylinders only serve to maintain constant contact with the ridge.
- the design is therefore advantageously made such that the maximum hydraulic pressure of the support cylinders is selected below 35%, preferably approximately 20%, of the hydraulic pressure of the support punches. In this way, it can be ensured that in a partial outbreak of the hanging wall under one of the four support cylinder, only this is hydraulically adjusted so far until a mountain contact is restored. The pressure that builds up in this trailing support cylinder can then be adjusted so that there is no change in position of the support plate. The support force is thus distributed in the mountains over the remaining, distributed in the specific case three support cylinders.
- the support plate can be connected in a conventional manner articulated with push rod elements with the rear frame of the tunneling machine.
- the control required for the readjustment of the pressure can be designed such that the support cylinders are connected to a hydraulic control maintaining a defined contact pressure, but, as already mentioned, after a partial outbreak under one of the support cylinders, this is merely adjusted hydraulically is and is not traced to a previously defined contact pressure.
- the supporting device In a particularly simple manner can be ensured by the supporting device according to the invention, a separation of the introduction of forces on the support device and the Ankerbohr- and setting devices, which is advantageously made the training so that the support stamp on the machine frame and that Ankerbohr- and -Setz annoyingen a frame of the charging device are supported.
- the geometrical design of the ridge cap is advantageously made such that the anchor drilling and setting devices in the Top view are arranged within the plane defined by the support cylinder surface.
- An improved protection of the operator can be achieved by per se known laterally adjustable shields and / or from the ridge cap laterally extendable roof elements.
- FIG. 2 shows a detailed view of the ridge cap
- FIG. 3 shows a schematic side view in which the mounting of the ridge cap and the positioning of the support punches can be seen
- FIG. 4 shows a plan view the propulsion or extraction machine according to the invention.
- FIG. 1 shows a tunneling and mining machine 1 equipped with the supporting device 2 according to the invention, "consisting of a U-shaped ridge cap 4 mounted pivotably on the supporting punches 3 at supporting points 10, which is equipped with hydraulic supporting cylinders 5.
- the ridge cap 4 is Anchor drilling and setting device is indicated by 7.
- the cutting roller 14 with the cutting heads 15 mounted thereon, as well as the discharge device 16 are also shown.
- Supporting punch (not pictured) moveable attack, with 10 are designated. With 11 the bearing eye is designated for the attack of push rods.
- FIGS. 1 and 2 show the U-shaped ridge cap 4 according to the invention in a side view.
- the reference numerals chosen in FIGS. 1 and 2 again designate the same components here.
- the pivot axis of the ridge cap 4 formed by the support rams 3 is located at a distance from the support cylinders 5, which defines the two lever arms a and b.
- the support cylinders 5 located on the shorter arm a can thus exert more pressure than the support cylinders 5 arranged on the long lever arm b.
- the push rod 6 is in turn connected via the bearing eye 11 to the support device and via a joint 12 to the frame of the tunneling machine 1 , To further derive ridge forces on the push rods 6 in the ground, a hydraulic punch 13 is provided.
- FIG. 4 shows the tunneling machine 1 in plan view, wherein the anchor drilling and setting device 7 can be inserted within the area spanned by the supporting cylinders 5 without collision with the supporting device 2.
- Other safety features here are ' the side shields 8 and the extendable from the ridge cap roof elements 9.
- the braced on the joints 11 and 12 between the ridge cap and the back of the machine push rods are denoted by 6.
- Also referred to are the bases 10 of the ridge cap 4 as well as the rear hydraulic ram 13, which give the tunneling machine 1 additional stability even when Schrämen.
