Abstract

The ground track for moving heavy loads, especially mechanized reinforcements, consists of a transport platform placed on the sliding surfaces of the connected troughs of the rake conveyor, between which it is centered by a lower guide in the shape of an annulus and locking pins. The transport platform is further provided with attachment holes and guide holes.

Description

The invention relates to an overhead track for moving heavy loads, in particular mechanized supports, in deep mines.

The known method of transporting heavy loads, in particular mechanized supports in deep mines, is twofold. The first method consists in shear transport directly along the front of the mine, the second method is shear transport along a track made of rails attached to wooden sleepers by means of connecting components, which is also located at the front of the mine. The transport of heavy loads, especially mechanized reinforcements, and the preparation of such a load, thus performed, represent considerable demands on material consumption at very low labor productivity and an increased risk of injury or damage to the excavated mine.

These drawbacks are minimized by the overhead conveyor track of the present invention, which is based on the transport platform being located on the sliding surfaces of the connected scraper conveyor troughs, centered between the lower ring-shaped guide and the locking pins. The conveyor platform is further provided with fastening and guiding openings. The advantage of the railroad for moving heavy loads according to the invention is the ease of laying the railroad, the possibility of reusing the scrap trays, reducing material costs, significantly increasing labor productivity during transport, reducing labor intensity and increase its safety. Last but not least, the preservation of the intact mine corridors during transport.

In the accompanying drawings, there is shown an exemplary embodiment of an elevated heavy rail conveyor according to the invention, wherein Fig. 1 is a partial cross-sectional view of the conveyor including the conveyed load, Fig. 2 is a plan view of an elevated archway and Fig. 3 , including a sectional elevation view.

An overhead conveyor for moving heavy loads is located at the front of a mine and consists of connected scraper conveyor troughs 1 of known design. The passages of the curves of the track and other changes of direction in the horizontal plane are solved by modified troughs Π1 »112. 113. On the sliding surfaces 11 of the connected troughs 2 of the ground track, a transport platform 2 is formed. The base plate 21 is provided with slots 23 for locking with locking pins 2 for straight travel and additional openings 24 for attaching the heavy loads to be transported 2 to the transport platform 2. In both directions of travel, guide openings 25 are provided on the transport platform 2 and locking units. To increase the 'stability, especially when passing the curved track is a land track provided with anchoring beams which are formed by beams "U ^M associated with the trays 2 by means of the handles 2» wherein the anchoring to invert the mine is provided with anchoring bolts 6 · transiting in In the curves of the track, the transport platform 2 is centered only by the lower guide 22.

Ground path for moving heavy loads žtMhů folds of the scraper conveyor of known design in a straight line ^{i <WlOtíky} tracks are formed from modified troughs 111, 112, 113 "formed on wfeto land track is loaded base plate 21 of the transport platform 2 which is against lateral deflection is provided by the lower guide 22 in the form of an annulus. For straight-ahead travel, the transport platform 2 is also secured against lateral deflection by locking pins 2 »inserted in the cut-outs 23« On the transport platform 2 a heavy load J is placed, in particular a section of mine mechanized reinforcement and secured against falling by a link chain , not drawn, threaded through the attachment holes 24 to the base plate 21.

A rope (not shown) of the pulling and securing unit (not shown) is fixed to the guide openings 25 during its operation. the conveying platform 2 with the heavy load 7 is skidded on the sliding surfaces 11 of the connected troughs. In order to provide greater stability when passing in curves, the track consisting of the connected trays 6 and the treated trays 6, 12, 14 will be anchored by the anchors 4 to the anchoring beams 6, and these are then anchored by bolts 6 to the beginning of the mine work. When passing in the curves of the track, the locking pins 6 are removed from the cutouts 23 of the base plate 21 of the transport platform 2.

In particular, the heavy-duty ground conveyor according to the invention can be advantageously used in underground mines, for transporting and equipping mining workplaces with heavy mechanized supports.
