Description

SUBSTANCE: invention relates to mine rail transport, in particular to mine rail track of cable underground roads in local workings.

The aim of the invention is to increase the reliability and efficiency of operation by distributing the loads on the swivel joints.

In FIG. 1 shows the proposed rail track with an underground cable car: in Fig. 2 - the same. plan view: in Fig. 3 - node I of FIG. 2 (modular track section): FIG. 4 - view A of Fig. 3: in FIG. 5 - node II of FIG. 3 (connection of the side lugs of the track sections): in FIG. 6 - section B-B of Fig. 4 (along the axis of fastening the pins on the sole of the rails).

In FIG. 1.2 shows an example of the installation of a cableway on the proposed rail track, which consists of a drive 1, a rail track 2, a towing cart 3, mine cars 4, a traction rope 5, an end block 6, a rack 7, outlet blocks 8, devices supporting rope 9, switch 10, cargo 11, traction arm 12, tensioner 13, anchors 14, load blocks 15, guide blocks 16.

The mine rail track 2 (Fig. 1-3) consists of modular sections L, containing segments of rails 17 of a symmetrical cross-section profile, each of which is made with a canteen a, a neck b AND a sole c (Fig. 6), with crossbars 18 in the form of sleepers.

Modular sections L (Fig. 4-6) are fastened together at the joints in the area of the sole along the axis of symmetry of the rail with lugs 19 and fingers 20, respectively, at the mating ends of the rails, as well as lugs 21 and 22 on the side surface along the sole and fingers 23 with lock washers 24 and cotter pins 25.

Modular sections L of the track 2 are transported to the shaft to the place of installation and installed end with lugs 19 in the direction of the tunneling face. Each subsequent modular section is put on top with fingers 20 into lugs 19, and lugs 21 and 22 of mating sections are locked with fingers 23, washers 24 and cotter pins 25, which prevents spontaneous removal 20 from lugs 19.

Longitudinal loads along the rail track, for example, braking forces from the composition of the road, are perceived by lugs 19 and pins 20, and vertical loads from mine cars at the junctions of rails by fingers 23 in lugs 21 and 22.

With the help of mounting holes on the crossbars of the sections, devices 9 are attached to support the rope 5 (Fig. 1.2).

The presence of gaps of the required tolerances in the lugs 19. 21 and 22 of fastening sections L provides the possibility of minor rotations of one section relative to the other in the vertical and horizontal plane.

Claims (1)

Claim Mine rail track, containing rails of a symmetrical profile, each of which is made with a head, neck and sole, mounted on sleepers and pivotally connected at the joints, distinguished by the fact that, in order to increase the reliability and efficiency of operation by distributing loads on the hinge joints , each pair of connected rails is connected by two hinges, vertical and horizontal, while the vertical one is made in the form of an eye fixed on the lower surface of the sole of one of the connected rails along the axis of its symmetry, and a vertical pin, which is installed in the hole of the eye, and the horizontal one is in in the form of eyes fixed on the sides of the soles of the joined rails, into the holes of which a finger is inserted and fixed.
