Definitions

  • the invention relates to a loading device for the extraction device of a tunneling or extraction machine, wherein the loading device is designed as a screw conveyor and interacts with at least one guide element for the material to be removed that is arranged outside the drive area of the extraction device, and the guide element of the loading device can be forcibly tracked.
  • the loading tools are designed as loading screws which can be swiveled arm-like on both sides of the conveying device with a supporting frame.
  • the loading screws are at least partially equipped with crushing tools on their screw web, the chutes serving as crushing abutments in this area.
  • the loading device thus simultaneously acts as an extraction organ.
  • the support frames can be swiveled independently of one another about their vertical axes in order to ensure that the entire machine can move around curves. Tunneling machines of the type mentioned are well suited for underground mining, where there are only low removal heights. In many cases, the actual extraction elements are connected upstream of the loading devices, so that the loading devices themselves only have to pick up the cut material falling to the ground and possibly have to shred them.
  • the invention is based on the generic part of the main patent claim, the task, the disadvantages of St.d.T. to eliminate and create a continuous flow of funding.
  • a variant of the invention shows that the components are approximately plate-shaped.
  • the plates are arranged to be longitudinally movable below the guide element and are preferably mounted to be longitudinally movable at least in their outer end regions by rollers or sliding guides.
  • the guide element is advanced. This device can also be used in underground construction, since it can only detect small removal heights.
  • the components forming the guide element as shell segments with a defined radius of curvature, which overlap one another in the circumferential direction and are at least partially movable in the circumferential direction.
  • an opening is provided through which the material is fed to a belt or plate conveyor for further removal.
  • the guide element has a rounded cross section and serves in the bottom receiving area of the Extraction element as a receiving element for the shell segments.
  • Such a device is universally suitable both for direct propulsion in the longitudinal direction and for cutting off by means of lifting and swiveling movements of the extraction member.
  • At least the shell segment facing the working area of the extraction element is rotatably supported at a defined radial distance about the horizontal axis of the extraction element or the loading device, connecting struts extending between the inner peripheral surface of the shell segments and the associated bearings.
  • the suspension or mounting of the components interacting with the guide element is preferably carried out in the area of the supporting structure of a chassis or the like.
  • the shell segments in their end regions (seen in the circumferential direction) with radial shoulders, which form stop surfaces for the retraction or extension of the shell segments.
  • the radial lugs engage in a claw-like manner and are at least partially arranged in corresponding guide grooves.
  • a telescopic extension or retraction in the circumferential direction can thus be ensured with a small space requirement. This arrangement ensures that irrespective of the removal height, the material obtained can always be conveyed away in the direction of the opening without significant material loss occurring in between.
  • the radial gap between the cup-shaped guide elements and the extraction member may be constant.
  • the material is usually broken during the loading process. It could be advantageous here to guide the shell segment initially located in the working area in such a way that an approximately funnel-shaped receiving area is formed.
  • the longitudinal or the rotary movement of the channel-shaped guide elements is preferably carried out by means of thrust elements, such as hydraulic cylinders, spindles, racks or the like.
  • the adjustment movement of the guide elements can be realized by contact switches or by optical switching devices. As a result, the stroke is set as a function of the dumping depth or the adaptation to the irregularly running work surface is achieved.
  • the control of the guide elements must be adapted to the application in each case.
  • the control can both inevitably, i.e. take place simultaneously with the height adjustment or also lead the height adjustment in order to ensure in any case that the material loss in the loading area is as small as possible.
  • FIG. 1 shows a mining element 1, which consists of a screw conveyor, not shown, which is provided with crushing elements in the outer peripheral region.
  • a loading process takes place at the same time along the slope direction of the auger.
  • at least one channel-shaped guide element is provided outside the working area of the extraction member 1.
  • this device which corresponds approximately to DE-PS 33 23 395, is only able to take up material cut off from a separate extraction organ in the bottom region 3 and, if necessary, to shred it.
  • the screw were designed as a lifting and lowering extraction device 1 at the same time, the material obtained would simply fall to the ground and would then have to be collected in subsequent steps. However, this reduces the overall efficiency.
  • the area the channel-shaped guide element 2 is modified so that it is able to follow the movements of the extraction member 1.
  • FIG. 1 this is done in such a way that at least one plate 4 which is longitudinally movable in the direction of advance is provided below the guide element 2.
  • the plate 4 or the plates are e.g. longitudinally guided by rollers 5,6.
  • Figure 1 shows the initial state.
  • the extraction member 1 is located on the floor 3 and the plate 4 or the plates are flush with the guide element 2 finally 7.
  • the longitudinal movement of the plates 4 takes place by means of hydraulic cylinders 8.
  • the longitudinal guides 5, 6 are fastened 9, 10 both in the lower region 11 of the guide element 2 and on the support structure 12 of a vehicle (not shown further).
  • the number 13 represents a through-opening through which the extracted and loaded material is fed onto a discharge conveyor 14.
  • FIG. 2 shows an alternative embodiment of the inventive concept.
  • the same components are provided with the same reference symbols.
  • the extraction member 1 and the guide element 2 are shown again, which serves here, among other things, as a receiving part of further shell segments 15, 16.
  • a through opening 13 is provided, which serves for the removal of the material obtained onto a take-off conveyor 14.
  • the guide element 2 is rigid, while the shell segments 15, 16 can be pivoted about the horizontal axis 17 of the extraction member 1.
  • Struts 20, 21 are arranged between bearings 18 and the inner circumferential surface 19 of the shell segments 15, 16, by means of which the rotary movement can be generated.
  • the attachment 22 of the bearing 18 is made directly on the support structure 23 of a chassis, not shown.
  • the rotary movement takes place via hydraulic cylinders 24 which engage the strut 21.
  • the curvature of the shell segments 15, 16 and of the guide element 2 corresponds approximately to the curvature of the extraction member 1.
  • the hydraulic cylinder 24 By actuating the hydraulic cylinder 24, the shell segments 15, 16 are retracted or extended.
  • the end regions of the shell segments 15, 16 are provided with cams 25, 26, 27, 28, at least the cams 26 engaging in corresponding guide grooves 29.
  • FIG. 3 corresponds to FIG. 1 with the difference that the plates 4 are extended in the direction of advance as soon as the extraction element 1 lifts off the ground and carries out a cut in the horizontal or vertical direction.
  • FIG. 4 can be seen, which corresponds to FIG. 2. It can also be seen here that the shell segments 15, 16 can be advanced in the circumferential direction depending on the working height of the extraction member 1.
  • the adjustment device is actuated by contact switches or the like.
  • the stroke H is set as a function of the depth of cut T or the adaptation to the irregularly running work surface is achieved.
