Definitions

  • the invention relates to an expansion aid for setting expansion segments and for securing the working face in sections and tunnels.
  • a known method for securing sections or tunnels, in particular in mines is, for example, the introduction of the extension by means of so-called front rails.
  • the individual extension elements must be set or assembled manually. Naturally, this process is particularly labor-intensive and time-consuming. It is particularly disadvantageous that work has to be carried out at least temporarily under the unsecured slope. An effective securing of the face is almost impossible.
  • the aim of the present invention is to significantly simplify and accelerate the route and tunnel construction and in particular to avoid any work in the unsecured space.
  • This object is achieved in that a supporting part is held at two support points and an adjoining support part protrudes freely into a route or a tunnel that the removal aid in route or tunnel is movable in the longitudinal direction and that a face safety device is attached to the support part of the removal aid.
  • the removal aid according to the invention makes it possible to prepare, mat and spread the ridge segments of the route or gallery extension in the rear, secured area of the route or gallery and then to set them fully automatically by ancestors of the removal aid on site. This also makes it much easier to insert and set the side parts of the extension.
  • the face protection attached to the support part can be folded out by means of a suitable actuating device, for example a compressed air-operated cable or chain hoist, a pull rod or a compressed air cylinder, and displaceable relative to the support part, so that it can be advanced beyond the end of the support part to the face.
  • the face safety device is extended and pressed against the face face as soon as the pile has been cleared away sufficiently. In order for a entering the ungeDivtenrfreige- le g th space is not required.
  • the removal aid can be easily hung up with trolleys on a monorail overhead conveyor and moved with one or two shunting trolleys.
  • the ridge segments can be placed particularly easily on the removal aid if it is rotatably mounted about the rear support point and can be lowered from the front support point using a suitable lifting device, preferably a chain or cable hoist operated by compressed air.
  • brackets are provided on the support part, which are adjustable in height and rotatable about their vertical axis. This makes it very easy to precisely align the ridge segments when setting.
  • the brackets are slidably mounted on the support part so that the distance between the brackets can be adapted to the required expansion or the joint length of the monorail overhead conveyor.
  • the brackets can be folded around a horizontal axis, so that the removal aid can be raised again by the height difference of the brackets after the removal has been set.
  • a further advantageous embodiment of the invention is to bend the intermediate part of the support part projecting beyond the front support point upwards, the support part being arranged parallel or almost parallel to the support part again.
  • the angle and length of this intermediate part are coordinated so that the height difference between the installation position of the ridge segments and the position of the support part of the raised removal aid is bridged.
  • the removal aid 1 is suspended from a supporting part 2 at two bases 5, 6 by means of trolleys 14 on a monorail overhead conveyor 15. At the rear base 5, the removal aid 1 is rotatably mounted, while it can be lowered from the front base 6 with a chain hoist 12 operated by compressed air. A support part 3 of the construction aid 1 protrudes freely into the section or the tunnel 4. To place ridge segments 10 in holders 7 of the support part 3, the removal aid 1 is moved back and lowered into the rear, secured space (FIG. 1). A face protection device 8 attached to the support part 3 is folded in and retracted. After placing, spreading and matting the ridge segments 10, the removal aid 1 is raised and moved after the blasting work on site (FIG.
  • An intermediate part 13 of the support member 2 is angled relative to the support member 2 and the support member 3 so that the support member 3 is parallel or almost parallel to the support member 2 and offset in height, so that the ridge segments 10 can be automatically brought into their final position.
  • the brackets 7 for receiving the ridge segments 10 are adjustable in height and rotatable about their vertical axis.
  • the removal aid 1 can be rotated around its longitudinal axis by a certain amount.
  • a further cable or chain hoist 21 or 22 each on suspension points 23 or 24 directly behind the cable or chain hoist 12 on each side of the support part 2 a further cable or chain hoist 21 or 22 each on suspension points 23 or 24. This makes it possible to simply and precisely align the ridge segments 10 when setting. Then the side parts of the track or tunnel extension can be set very easily and quickly.
  • Required auxiliary devices are provided on removal aid 1.
  • the brackets 7 are mounted on the support member 3 so as to be longitudinally displaceable. The distance between the brackets 7 can, if necessary, be adapted to different setting distances between the individual segments of the expansion. After the removal has been introduced, the holders 7 are folded over a horizontal axis 3C and the removal aid 1 is raised again to increase the working space by the height difference of the holders 7.
  • the face protection 8 is mounted with its one end 9 on a support 28 rotatable about a horizontal axis.
  • the support 28 is attached to the support part 3 of the removal aid 1 so that it can be pushed out.
  • One end of a strut 11 engages the face 8 at a sufficient distance from the axis of rotation.
  • the other end of the strut 11 is connected to a sliding carriage 29 on the support 28.
  • the face safety device 8 is expanded with a chain hoist 25 operated by compressed air, which acts on the guide part 27 and moves it on the support 28, until its free end 26 lies on the face face 20. If the guide part 27 is moved further, the support 28 pushes out of the support part 3 against the working face 20 until the working face securing device is in full contact (FIG. 3).
  • removal aid 1 In addition to other auxiliary devices, supply connections for compressed air and electricity are provided on the removal aid 1.
  • the removal aid 1 with the face protection 8 remains on site during the entire workflow, such as shoring, drilling, loading the explosive holes and coupling the detonator wires.
