Definitions

  • the invention relates to a device for mining rock material, ores, coal or the like.
  • rotating tools which are rotatably mounted on a liftable and lowerable cantilever arm, in particular a surface mining device with rotation axes arranged transversely to the longitudinal axis of the cantilever arm for tools equipped with chisels Rollers or heads, the rotating tools being mounted on a support, the support being slidably mounted on the extension arm transversely to the longitudinal axis of the extension arm, the free end of the extension arm having an enlarged head on which a guide for the support is fixed.
  • Known surface mining devices mostly have their own undercarriage, in particular caterpillar undercarriage, and can be moved by their own drive.
  • a loading device can be connected to the undercarriage in the direction of the material to be dismantled which detects the dismantled material and forwards it to conveyors.
  • the cantilever arm can only be pivoted about an approximately horizontal axis and thus only in the vertical direction.
  • the working width at a given location of the machine is limited to the width of the loosening tools, and in order to be able to coat a larger width, the surface mining device must be moved and moved to a new position.
  • the support was shifted laterally in one direction during the downward cutting, it was possible to work continuously without separate devices for breaking the ribs, provided the side slope angle was set sufficiently flat.
  • a mining machine for underground operation in which a support that is displaceable transversely to the longitudinal axis of the boom arm is arranged on a cantilever arm that can be pivoted in the vertical direction, on which superimposed cutting heads are rotatably mounted about vertical axes of rotation.
  • a relatively wide head of the cantilever arm must be selected for adequate guidance of the support in order to ensure a sufficient displacement path transverse to the longitudinal axis of the cantilever arm.
  • tubular slide bearings connected to it are carried by claws of the support, so that a large guide length and thus a large width of the head are also required for adequate support.
  • a cylinder-piston unit is used to shift the support relative to the extension arm.
  • the invention is now based on a device of the type mentioned and aims to increase the detectable width of rock to be mined without the device itself and without having to increase the drive power for the rotating tools at the same time.
  • the invention further aims to be able to adjust the side slope angle in any way and to be able to cut vertical side slopes without the aid of additional measures.
  • the invention consists essentially in the fact that the guide for the support is formed by bars arranged transversely to the longitudinal axis of the cantilever arm, which are at least partially encompassed by part of the support, that the guides on the cantilever arm at least three points of their axial Length supported on the head, that the guides are connected to an intermediate carrier, that the intermediate carrier has additional guides for the support, that the intermediate carrier is displaceable relative to the head and the support relative to the intermediate carrier via a drive connected to both parts, that the Intermediate carrier, the guides of the head and the support encompassing bearings, that the bearing distances of the guides on the head, on the support and on the intermediate carrier are approximately the same and that the guides on the head and the support of pairs in each case in an Eb penetrated by the longitudinal axis of the cantilever arm arranged rods or tubes are formed.
  • the rotating tools are mounted on a support that can be moved transversely to the longitudinal axis of the cantilever arm via an intermediate carrier on the cantilever arm, a larger width can be coated with the same position of the chassis of the device by moving the support and the intermediate carrier, the drive power for the rotating tools not elevated must become. Even large reaction forces are safely absorbed by the head for managing the support.
  • the guide for the support is formed by bars arranged transversely to the longitudinal axis of the cantilever arm, which are at least partially encompassed by part of the support. In this way, a particularly simple guidance for the transverse displacement of the support is created and, at the same time, reliable support of the reaction forces is possible.
  • the design is such that the guides on the cantilever arm are supported on the head at at least three points along their axial length.
  • the guides are at least partially encompassed.
  • the possible displacement path of the support is defined transversely to the longitudinal axis of the cantilever arm by adjacent support points on the head.
  • the design according to the invention is such that the guides are connected to an intermediate carrier, that the intermediate carrier has additional guides for the support and that the intermediate carrier relative to Head and the support is displaceable relative to the intermediate carrier via a drive connected to both parts.
  • Such an intermediate carrier forms a kind of telescope together with the support, and the possible displacement width can be almost doubled in comparison with the distance between the supports of the guide rods.
  • the drive for shifting the intermediate support and support can be particularly special be formed in a simple manner by cylinder-piston units, and a reliable absorption of reaction forces is further ensured in that the intermediate carrier has bearings around the guides of the head and the support.
  • the guides of the head and the support are each formed by rods, which are fixed in sections of their length on the head or on the support, the encompassing bearings of the intermediate carrier of bearing eyes can be carried in a bearing plate of the guides of the head or of the support Intermediate carrier be formed.
  • the training is further made according to the invention so that the bearing distances of the guides on the head, on the support and on the intermediate carrier are approximately the same.
  • the guides on the head and on the support are furthermore formed in pairs by rods or tubes arranged in a plane penetrated by the longitudinal axis of the cantilever arm.
  • the bearings in the intermediate carrier can advantageously be designed so that the guides of the head and the support are held in mutually parallel planes.
  • the design is advantageously made such that the guides are supported at four points along their axial length.
  • the rotary drive for the rotating tools is advantageously fixed on the support.
  • the additional weight of such a rotary drive is easily absorbed by the special design of the mounting and guidance of the components to one another.
  • the aim is advantageously to keep the remaining rock rib between adjacent heads or rollers as small as possible.
  • a preferred device for carrying out the method characterized in that a plurality of separate drive motors are provided for the rotatable heads or rollers.
  • Such a plurality of motors each have to drive a smaller number of rollers or heads, so that the gears required for this purpose, which are arranged in the carrier arms between adjacent rollers or heads, can be made narrower.
  • the device is advantageously designed so that a drive motor is provided for every two adjacent rollers or heads.
  • the device according to the invention is advantageously further developed such that the sliding drive for the support is designed with double-acting hydraulic or pneumatic cylinder-piston units, the working spaces of which are connected to a valve arrangement which acts alternately on the working spaces with fluid and each opposite work room opens.
  • a valve arrangement with an adjustable switching frequency is advantageously selected in order to be able to better adapt the feed rate to the respective rock properties.
  • the device is advantageously developed so that limit switches, in particular adjustable limit switches for reversing the sliding movement of the support, are arranged in the displacement path of the support.
  • the limit switches can be set in a particularly simple manner to the respective construction-related width of the remaining rib between adjacent rotating rollers or heads.
  • the device according to the invention can be used with rotating tools, which are rotatably mounted on a boom arm that can be raised and lowered, in particular a surface mining device with a cross-section to the longitudinal axis of the Cantilever arms arranged rotation axes for rollers or heads equipped with chisels, in which the rotating tools are mounted on a support and the support is slidably mounted on the cantilever arm transversely to the longitudinal axis of the cantilever arm and are used for a method for removing material in which the sliding drive of the support is used is driven in a substantially vertical direction to reciprocating movement during the advancement of the carrier.
  • Such an oscillating movement of the carrier prevents the carrier arranged between adjacent rotating heads or rollers from sitting on a rock rib with the gear for the rollers or heads during downward cutting, since such rock ribs can be cut away in good time by the oscillating movement of the carrier.
  • the method is advantageously carried out in such a way that the stroke of the reciprocating movement between the reversal points thereof is selected to be at least equal to the distance of adjacent rolls or heads measured in the axial direction.
  • the method is advantageously carried out in such a way that the ratio of the speed of the feed movement in a substantially vertical direction to the stroke frequency of the support is chosen to be less than or equal to the height of the rib in a substantially horizontal direction.
  • the ratio of the speed of the feed movement in a substantially vertical direction to the stroke frequency of the support is chosen to be less than or equal to the height of the rib in a substantially horizontal direction.
  • the method according to the invention can in principle be carried out with any device described, the installation of a corresponding valve arrangement for the oscillation drive of the support being necessary in the case of special designs.
  • the large lateral adjustment paths as would be possible with a telescopically interlocking guide of the support, are not absolutely necessary for sharpening in a substantially vertical direction, since in this case only an oscillating movement corresponding to the remaining rock ribs between adjacent rollers or heads is required.
  • the stroke required for this is relatively small, so that a large adjustability is not necessary.
  • a large adjustability in the lateral direction together with the oscillating movement of the support enables the setting of any slope angle and a better adaptation to different rock properties with the lowest possible power requirement.
