Definitions

  • the invention relates to a removal assembly platform for lines of underground operations according to the preamble of claim l.
  • the working platform of such platforms can generally be moved on a track laid in the top of the line with the help of trolleys. In addition, the platform can be raised and lowered opposite the track.
  • the designated connection consoles of the work platform are used to connect the trolleys and / or the hoists with which these functions are carried out.
  • the floor plan of the work platform is usually longer in its longitudinal dimension than transverse to it, the trolleys are usually attached so that the front part of the stage with a predetermined length in the undeveloped in the track location Section part can be moved.
  • a manipulator usually interacts with this front part of the stage, mainly for parts of the track extension, preferably for several ridge segments combined to form a canopy.
  • the removal assembly platform can also have other devices, for example movable platform parts, which, in their effective position, make it possible to drill the track location, possibly also during the final assembly of the track extension.
  • such extension platforms are used in the track location and at a remote location connected to it by the track.
  • the removal components mentioned are preferably pre-assembled on this on the removal manipulator in the lowered position of the work platform. Then you lift the work platform with the help of the lifting equipment so that you can spend it in its on-site position across the various facilities of the route. There the stage is locked, so that the work platform forms a reliable abutment for the removal manipulator and other mechanical equipment of the stage, as well as a safe standing area for the workers involved in the assembly of the removal and possibly for the drilling equipment.
  • such an extension assembly platform can also be provided with an extension which can be braced with the face, which prevents the stone and coal from falling there.
  • Removal assembly platforms are known for the purposes described at the outset, which remove the reaction forces emanating from the connection brackets via two parallel I-section supports, on which the actual work platform is suspended in a height-adjustable manner (DE-PS 23 60 726). Such removal assembly platforms have a relatively complicated structure and a considerable overall weight.
  • the invention is therefore based on another of the known removal assembly platforms (DE-PS 28 11 580), in which the stage supports and the surface of the work platform lie in one plane.
  • that part of the work platform which is not formed by the upper side of the stage girders designed as hollow girders is composed of pontoon-like elements which are screwed partly to one another and partly to the hollow girders.
  • the connection brackets are attached to the top of the supports, which relieve the elements of the reaction forces.
  • the disadvantage of this stage construction is that the beams have to be connected to practically all elements in order to ensure sufficient strength of the work platform. This then results in relatively long beams in the longitudinal direction, the high weights of which can be reduced by the hollow beam formation and their poor transportability one tries to compensate by pluggable carrier sections.
  • the invention is based on the object of reducing the necessary beam lengths and accordingly increasing the load-bearing capacity of the platform parts consisting of the elements fastened to one another.
  • the edges of one another in at least one surface dimension of the work platform of adjacent elements are allowed to jump in the direction of this dimension, a joint offset is created which ensures a sufficient bending tensile strength of the element composite. Therefore, one can get by with short carrier lengths that only absorb the reaction forces of one or more connection brackets simultaneously and transmit and distribute them from below to the elements or plates or several elements.
  • connection brackets After one assumes an essentially predetermined transverse spacing of the connection brackets, which should be as large as possible for reasons of stability and, on the other hand, wants to keep the transverse dimensions of the working platform as small as possible, among other things in order to be able to move the working platform as high as possible above the track base, the distance becomes Connection brackets from the longitudinal edges of the work platform increasingly less.
  • the shortening of the carrier or their arrangement achievable according to the invention then allows the characteristics of the To realize claim 2 and thereby to dispense with a foldability of the elements that enlarge the work platform.
  • the stability of the removal assembly platform usually requires four trolleys, which are arranged at the corners of a square or rectangle enclosed by the longitudinal and transverse edges of the platform and can be moved on two hanging rails of the track.
  • the hoists carry the working platform on the connection brackets and enable the adjustment of the respective working height of the platform.
  • the removal assembly platform is usually equipped with a removal manipulator, it can also be used to assemble a corresponding number of structures on site when the removal manipulator is set up to accommodate several ridge segments of the track extension at the same time. In the latter case, a cap screen is preassembled in a section of the route lying behind the route location with the work platform lowered, which is brought into the route location by the removal assembly platform in the raised state and there under the exposed roof is raised. Then the removal assembly platform is determined so that the canopy can first be used as a preliminary extension for securing and then for the final assembly of the relevant track construction.
  • the extension platform is particularly heavily loaded and must therefore be secured against breakage of the traction devices of the hoists.
  • the hoists must be adapted by their structure to the relative simplicity of the lifting operations with sufficient height adjustability of the working platform, but on the other hand, the structure of the hoists must also ensure a simple and safe design of the stage suspension, which is effective when the hoists are switched off.
  • DBP 23 60 726 It is known (DBP 23 60 726) to use the lifting trolleys developed for underground transportation on monorail overhead conveyors as hoists and to connect their traction devices to a stage frame consisting of several supports, to which the work platform is attached in a height-adjustable manner with the aid of several hydraulic push piston gears.
  • the stage frame In order to be able to reach a sufficient height of the work platform, the stage frame must be be lifted up to just below the roof. This forces a relatively complicated stage suspension. It consists of several support hooks that can be swiveled into the stage frame and a support roller arranged at the rear end, which rolls on a hanging rail. If one takes into account the large number of hoists, the overall structure is too complex.
  • the invention is based on another of the previously known assembly platforms (DBP 28 11 580).
  • the beams that form the stage frame are integrated into the work platform, and hollow beams that can be plugged together are also used, with which edges of sheet metal elements that can be screwed together are screwed in order to ensure the required bending tensile strength of the platform.
  • the connection brackets are attached to the hollow girders and not only serve to connect the flexible traction means of the known lifting trolleys, with which the stage can be moved on the monorail rails forming the track and is adjustable in height relative to these.
  • the connection brackets also take up the stage suspension.
  • This consists of a telescopic tube arrangement assigned to each connection console, which is attached at one end to the trolley and can be connected to the relevant connection console by means of plug-in bolts when the work platform is raised.
  • a telescopic tube arrangement assigned to each connection console, which is attached at one end to the trolley and can be connected to the relevant connection console by means of plug-in bolts when the work platform is raised.
  • plug-in bolts When the work platform is raised.
  • the telescopic tubes attached to the rear end prevent the work platform from tipping over because of their mutual positive locking and the positive locking with the trolleys and connection brackets.
  • the invention aims to simplify the hoists in such a way that the lifting trolleys previously required can be dispensed with and the drives of the traction means must be arranged in such a way that the connection brackets for the connection of the known stage suspension or a similarly practical suspension also remain usable.
  • the drives can be realized with single or double-acting, single or multiple thrust piston drives on the one hand and both ends of the just set the articulated traction device to the relevant connection console, which means that simple trolleys are used and connection consoles are kept to which the stage suspension can be connected.
  • the length of the elements in which the thrust piston gears are accommodated generally does not depend on the extended length of the thrust piston gears, but on various other aspects.
  • the implementation of the invention with the features of claim 12 is expedient, because then the accommodation of the traction drive is possible with a stroke that exceeds the available length within the elements.
  • FIG. 3 to 5 consists of a work platform elements 1 made of sheet metal 2, which is a strength part 3 of the surface in detail from the F. l and 2 recognizable work platform.
  • the sheet has double-folded longitudinal edges 4 and 5; 6 and 7. This results in the C-shaped cross section shown in FIG. 5, the downward-pointing legs 12 and 14 of which, as shown in FIG. 3, are provided with cutouts 15 and 16, respectively.
  • the longer axis 17 of these congruent recesses 15 and 16 runs in the direction of the longitudinal edges 4 and 5; 6 or 7, while the shorter axis 18 is perpendicular thereto.
  • the edges of the sheet carry 2 angle profiles legs 8, 9 and 10, 11, which are perpendicular to each other 16 corresponds and therefore allows the screwing of the element on the narrow sides with other elements.
  • the sheet 2 is stiffened because of its relatively large extension in the longitudinal direction of angle profile sections 24, 25, which are at a distance from the transverse edges 19, 20 and at a mutual distance from cross each other and are attached so that one leg 27 perpendicular to the sheet 2 and the other leg 28 parallel to the folds 5, 7.
  • the element 30 shown in FIGS. 6 and 7 corresponds to one half of the element 1 divided in its longitudinal center and is therefore provided with corresponding reference numerals. Since it lacks bends or angular profiles on its longitudinal edge 31 corresponding to the dividing line, it can be oriented outwards with this longitudinal edge 31 and form an outer element of the work platform.

  • the two flanges 51 and 52 of the brackets in turn carry holes 53, 54 for the connection of hoists, support chains, support hooks or the like. These devices are not shown.
  • the two hollow beams 49 and 55 can be connected in the manner shown in FIG. 10 with only one bracket 38, 39 but also with a plurality of brackets, preferably arranged next to one another in the transverse direction.
  • the element 36 with two brackets 38, 39 arranged on its transverse edges can also be provided with only one bracket of this type, which is then expediently located in the middle between the angle profile sections 24 and 25 in the embodiment shown in FIG 10 obvious manner is attached.
  • the element 56 according to FIGS. 12 to 14 can correspond to element 32, but also to element 1.

  • the reference numerals of FIG. 5 are entered accordingly in FIG. 12.
  • the angular profile of the transverse edge 20 with the legs 10 and 11 has been omitted, so that the outer edge 57 corresponding to the transverse edge is free.

  • This kit can be expanded by elements of a third type, which make up half of an element 1, which can be assembled from two elements 32 of a different type; this element can be provided with a free edge 31.
  • the kit can have elements of one and the other type 1, 32, which are provided with the drawer-shaped element 67.
  • FIG. 1 An embodiment of a work platform resulting from such a modular system is shown in FIG. 1.
  • the platform front side 70 is formed here by an element 1, which is provided on its two transverse edges 4 and 6 with a drawer-shaped element 67 and determines the transverse dimensions of the platform with its length. It is attached to the platform section 71 with one of its longitudinal edges 4.

  • the transverse edges of the elements connected to one another are offset. This increases the bending tensile strength of the platform, especially in the longitudinal direction of the route.
  • the carriers 49, 55 are also square tubes. If these tubes are arranged in the transverse direction of the elements, they can interact with a hole program for the bow bolts 43 and 44, which enables the brackets to be adjusted transversely.
