Definitions

  • the invention relates to a lowering machine, in particular for use in the Routes in underground mining, the bottom of which is due to convergence Lifts must be lowered back to normal level with a machine frame, a running gear and a cutting device that can be inserted into the track base the one about vertically arranged and horizontally movable and about a support arm held rollers and is assigned a conveyor via which the solved Pile is removed behind the machine frame.
  • Lowering machines are used in underground mining, which are due to of mining measures in neighboring seams or for other reasons swollen up Lower the track floor so far that it is used for subsidies, weather management and for the cross-section required for the journey is available again.
  • sinkers are used both in temporarily closed routes, as well as in such Companies in which the mining operation or conveyor operation continues.
  • the lower loaders therefore have to be very flexible. The dimensions are because of the cramped conditions to keep small, but sufficient forces in the area of the to be lowered Track sole must be brought in to safely loosen the rock.
  • DE-PS 501 703 discloses a extraction device which can be used as a sinking machine known, on the pivotable cantilever arm a two-part cutting device is rotatably mounted.
  • the cutting device consists of two super-heavy working and arranged on the same drive shaft, on its outer circumference Scraper or fangs are attached.
  • the scrapers or fangs loosen the pending Material, obviously lignite, take it with it when it is turned and hand it over it on a first conveyor, which it on, on the machine frame of the extraction device provided, intermediate funding passes.
  • a disadvantage is the relatively wide Design of the scraping wheels arranged on the boom as well as the low drive power, which can be transferred because the first conveyor and the scrapers over the same drive must be supplied. Rock, like it comes from lowering, can therefore not with such a device without further auxiliary units or separate solving work can be won.
  • the overall height is particularly disadvantageous of such a device.
  • a sinking machine that works in principle is similar to DE-OS 29 11 705 remove.
  • a cutting roller arranged at the head of a cutting arm works here. which is covered with fangs or the like, while being used for crushing and loosening of the rock, as well as for its removal in Towards the conveyor.
  • a similar sinking machine is also DE-PS 21 60 643, which works similarly to the aforementioned sinking machine and which has the same disadvantages in that the rotating around a horizontal axis Cutting roller can only be operated with a correspondingly complex extension arm, to absorb the forces that arise. To make matters worse, these known machines caterpillars are used, which only a limited Offer the possibility of safely transferring the forces to be absorbed.
  • the tunnel boring machine known from US Pat. No. 4,664,449 are two Cutting rollers at a fixed distance from each other the front beam of a support arm assigned, which runs at right angles to the support arm and has a cylinder, over which the cutting rollers are pushed back and forth horizontally.
  • the only arm that carries the two cutting rollers can be pivoted around a joint in the arch the height can be pivoted.
  • the disadvantage is that due to the fixed distance of the two cutting rollers only both cutting rollers together a slump can produce what only with high restoring forces and with enormous force and Energy expenditure is possible.
  • 3,472,555 also shows a machine on the other single support arm two leveling discs are attached, which have a central drive be driven evenly, but at a predetermined distance from each other are fixed. Even with such a smoothing disk device, only working with two leveling or smoothing discs at the same time and at the specified distance possible.
  • the invention is therefore based on the object of a sinking machine to develop that making the necessary break-in easier and at the same time the necessary restoring forces must always be safely applied.
  • rollers of the Cutting device as vertically arranged, swiveling and height adjustable Swivel rollers are formed, which (each) are held by support arms with which at the same time machine frame serving as abutment connected and on the side parts of the machine frame rotatable and a compact, a base plate of the machine frame assigned, carrying arm displacement are shifted.
  • the swivel rollers are height adjustable trained, they can differ when driving through troughs and saddles compensate easily, which in turn provides the certainty that the cutting forces, as well as the necessary restoring forces, the lowest possible loads to be endured or taken up.
  • Another advantage is that independent on the hardness of the lying layers due to the parallel working method necessary restoring forces are to be applied well. Training requirements of the abutment are also due to the opposite working method the swivel rollers and the resulting compensation of the restoring forces weakened.
  • the theory also gives you the option of using a single swivel roller to work, then only the advantage of compensation the restoring forces would be eliminated.
  • the entire sinking machine could do that build narrower, but it must be taken into account that through the use two swivel rollers already largely adapt to different track widths becomes possible.
  • the support arms of the Machine frames are assigned and height adjustable. According to further training it is envisaged that the support arm shift via hydraulic actuating cylinders are height adjustable, so that much simpler support arms can be used can come that have no joints themselves, but rather only the support arm displacement with their actuating cylinders need to move the swivel rollers in the To be able to adjust height.
  • the support arms are the swivel rollers Swivel from the route joint to the middle of the route. This is now done according to a development of the invention in that the support arms via integrated Have swivel cylinders that enable correspondingly easy swiveling, even when the necessary pressure is applied to the swivel rollers.
  • a stable lowering machine that moves according to the progress of mining can, but still has optimal standing properties, is the one at the machine frame from a front, which receives the support arm displacement, Base plate and a rear abutment, which can be braced against the track joints and via hydraulic screeching cylinders and skids that act as chassis are mutually movable.
  • Base plate and a rear abutment which can be braced against the track joints and via hydraulic screeching cylinders and skids that act as chassis are mutually movable.
  • the hydraulic screeching cylinders spherically displaced and bends between base plate and abutment are trained to be approving. This allows differences in height between the base plate and abutments can be easily accommodated without the hydraulic be charged.
  • the base plate can also be targeted raised or lowered to optimally lower the troughs and saddles to be able to.
  • the appropriate step and at the same time the application of the necessary Pressure on the swivel rollers can be achieved by the base plate and the abutment against claws and support cylinders independently of each other Route joints can be braced.
  • the claws and the support cylinders make that possible Applying the necessary forces without the risk that the route expansion, against which the claws are moved, including losing stability.
  • the claws ensure that the forces are applied to several butt segments of the extension simultaneously.
  • the support arm displacement is provided that the base plate from a Conveyor-receiving, middle part, two, the claw-receiving, side parts and adapter strips inserted between them.
  • the individual parts absorb loads and forces without the other part is influenced.
  • the possibility is given by interposed adapter strips the width and thus the design of the respective countersink to specify exactly according to the requirements.
  • the side parts are attached to the central part via the adapter strips, the adapter pieces or Adapter strips each have widths that meet the requirements.
  • the loading of loosened piles is carried out by a special execution of the Midsection or the base plate facilitated, it being provided that the base plate at the front edge with a shovel-shaped loading ramp with side loading aprons and loading bar is equipped. Because of this training it will be in Schrämgasse the remaining piles are pushed onto the front part of the base plate at the back, the blade-shaped design favors this. The pile in this way the conveyor is forced during the further reverse operations fed, so that slippage of piles from the work area is impossible. Loading aprons on the side also capture the pile lying near the joint and feed it to the conveyor via funnel-shaped mounting plates.
  • the work of level control is favored by the fact that the rear lower edge the base plate is chamfered. Via the corresponding control cylinder the base plate can thus be brought into a rising position without there is an obstruction between the base plate and the abutment.
  • the abutment like the base plate, is braced against the impacts.
  • the abutment can perform this function particularly well if it is in the middle section, Side parts and adapter strips divided and with a central support for the conveyor is equipped that the relative movements between conveyor and abutment is receiving.
  • the central support for the conveyor can Relative movements between abutment and conveyor during the back without problems record and also allows in curves, bends and similar positions.
  • the conveyor is constructed according to the invention so that it consists of a rigid Frame exists, which is placed on the support of the abutment and on the front part the base plate is horizontally rotatable. In this way he can Driving through troughs from the base plate or when driving through saddles lift the abutment without affecting its function.
  • the base plate and abutment are approximately at the level of the center of gravity of the countersinking machine additionally connected to the level control.
  • the level control is formed by level control cylinders that are rigid on rockers sit and, like this, rotatably attached to the base plate and via a universal joint with pushrods slidably mounted in the abutment in the longitudinal direction are connected.
  • the abutment-side stop takes place via two push rods, such as mentioned, which is displaceable in the route direction in the abutment and on the described Gimbally connected to the wings.
  • Level control can raise the front part of the base plate (for example, to go over a lying skid or with an increasing driving style), the lying pressure of the loading ramp reinforced (avoiding climbing, improving the clearing effect) or the Base plate in the - then undercut - lying down (submerged Mode). This increases the versatility of the new lowering machine.
  • the invention is particularly characterized in that a lowering machine is created that is versatile, small in terms of dimensions, because it skillfully absorbs the necessary restoring forces and the cutting forces has a simple and very practical construction.
  • the overall optimal Dimensioned countersink can practically in sections of any cross-section, d. H. Width, can be used because the possibility is given via the adapter strips is to quickly and easily adjust the width of the lowering machine to the width of the route, the two swivel rollers ensure that the optimal application of the necessary cutting forces are so skillfully brought into the mountains that the individual components can still be kept small.
  • the individual parts are coordinated and designed so that the necessary cutting performance with smallest possible units is provided, but also the necessary restoring forces either reduced so far or at least absorbed so well that they hinder operation and enable the most favorable design possible.
  • Advantageous is further that with high cutting performance, care is taken that the Hauftechnik is always safely discharged and that, due to the training, either with a stationary swivel roller or just worked with one swivel roller can be, if the route width or the equipment of the route requires it.
