LAYOUT OF MECHANICAL CLEANING DEVICES FOR TRACKS, ESPECIALLY V / UNDERGROUND MINES

The subject of the invention is a system of devices for mechanical cleaning of tracks, especially in underground mines, in order to remove heaps of track contamination and between tracks of traction transport with filling material and transported debris.

Until now, the removal of dirt piles of tracks and traction railroad tracks in the underground of underground mines has been done manually by moving the hardened dirt mounds with pickaxes and manually loading these pollutants into the traction vehicles. The above method of removing contamination of tracks in the underground of mines was inefficient and very labor-intensive, as a result of which most of these tracks remained constantly contaminated, making it difficult to carry out the operation and proper maintenance of underground traction tracks.

The conducted tests of mechanical removal of the piles of contamination from the underground traction tracks did not give satisfactory results due to the inability to obtain adequate strength and proper interaction of the tested design solutions in difficult operating conditions.

. It is known to design devices for cleaning the track, especially mine underground railway, consisting of a strut lifting an arm upwards in the form of two broken electrically insulated beams terminated with a scooping bucket. These beams are connected to each other by the strut axis and the hitch axis with a flat hitch mounted on it, which connects the devices with the locomotive. The strut is mounted on the axis that connects the beam in rotation and consists of at least one pair of lugs with side seats overlapping the rails and branches, which, by driving into the ground between the rails, initiates the uplift of the frame. The rotation of the strut is limited by the bolt detachably attached to the frame. About the legs of the struts The bumper is attached to the limits 150 552

The moaning ride of the wagon for loading the excavated material Dipper bucket It is pivotally connected to the frame beams by means of pins 1 It is equipped with limiting stops Its rotation, guides guide between the rails 1 ratchet mechanism that blocks its rotation

The above device for cleaning the underground mine track is alternately pushed or clawed by the locomotive, and the spoil from the track taken from the bucket is lifted up by means of a strut 1 poured into the wagon, which is maneuvered by the second locomotive.

The applied method of mechanical cleaning of the track and loading into the wagons did not give the possibility of obtaining the desired efficiency and was not used in practice. An additional inconvenience of the above solution I et the possibility of initiating the risk of electric shock by striking the suspended track with a bare electric traction wire while manipulating the arm of the device with I scoop the spoon

The aim of the invention is to avoid the inconvenience of the existing methods of cleaning the traction tracks in the underground of mines and devices for the use of these methods and to develop a simple, reliable set of devices that would enable a highly efficient, safe mechanical movement and loading of debris from the tracks and underground traction intertracks.

This goal was achieved by the invention of a system of devices for mechanical cleaning of tracks, especially in underground mines, to remove heaps of contamination with the underfloor material and transported excavated material, and between tracks of the traction transport, including a track locomotive pulled along the track, a device that moves the pollution and the track load-bearing device with the load The track moving device is seated on the platform of the four-wheeled chassis and includes an adjustable plate with vertically positioned arms ending at the bottom with tear-off knives, while the track loading device is positioned on the four-wheel chassis platform. 1 includes a scraper conveyor suspended on an articulated support structure. platform, ended with a turning supported on an additional wheelset. A scraper loader is attached to the turning face, equipped with a gable table with the proper part inclined at an angle of 20 ° in relation to the longitudinal line of the rail head and an attacking part located at an angle of 25 ° to this line. In the attacking part of the scraper loader table, two trapezoid-shaped cuts are made to freely pass the rails of the track and the splint bolts and rail washers protruding above the sleepers with the bolts or a clamp. The head of the piston rod of the pneumatic actuator, mounted on the platform of the four-wheeled chassis, is rotatably connected to the chute of the scraper conveyor.

The use of the system of devices according to the invention made it possible to significantly increase the efficiency and safety of work with a fully mechanized method of starting and loading the heaps of pollutants from the tracks and underground traction tracks.

The purposeful construction of independent coupled track devices for sprinkling pollutants and for loading pollutants allows to obtain a reliable system of devices for failure-free mechanical cleaning of tracks under difficult operating conditions in underground mines.

The subject matter of the invention is illustrated in an exemplary embodiment in the drawing, in which Fig. 1 shows a dirt-moving track device in a system of mechanical cleaning devices for underground tracks in a side view, Fig. 2 shows a cross-section AA of the above actuator in a front view, Fig. 3 shows the track loading device in a side view, while fig. 4 shows the head part of the above loading device in a top view

The system of devices according to the invention is 1 track starting device connected to the locomotive 2 pollution and track loading device 3 pollution

150 552 with a coupled wagon 4, which is also adapted to independent operation, cited and powered by another locomotive on rails 5 track tracks A screw drive 9 is attached from the top centrally for adjustment by means of a screw 10, movable in the yield of the plate 11 with arms 12 vertically positioned in two rows, ending at the bottom with catches 13 with replaceable ripping knives 14 The platform 6 is equipped with a counterweight 15 A track device The loading pollutant is mounted on the platform 16 of the four-wheel chassis 17 and is a scraper conveyor 16 suspended on the articulation 19 by its drive 20 on the supporting structure 21 of the platform 16 The scraper conveyor 18 ends with a turning 22 supported on an additional wheel set 23 A loader is attached to the turning face 22 scraper 24, equip fitted with a gable table 25 with a proper part 25a inclined at an angle of 20 ° to the longitudinal line of the rail head 5 and an attacking part 25b inclined at an angle of 25 ° to this line. In the attacking part 25b of the gable table 25, two cutouts 26a are made and 26b, trapezoidal shape to freely bypass the track 5 of the track and projecting bolts and rail washers above the sleepers with screws or splints articulated on the platform 16 of the four-wheel undercarriage 17 · The sides of the gable table 25 are provided with protective boards 32 to prevent the debris from falling outside of the scraper 24.

For controlling the drive 20 of the scraper conveyor 18 and the pneumatic actuator 31 and 1 of auxiliary installations, the control board 33 is installed on the platform of the 16-track loading device 3 pollutants, supplied with compressed air from the locomotive 1 or from the mine network.
