Abstract

The invention relates to a device for shifting the rail-sleep grid, mainly a rail-sleep grid, on which belt conveyors are installed, operating under conditions of open-cast mining. The purpose of the invention is to increase the reliability of the advancement device by reducing the loads acting in the transverse J 2 direction during deformation of the rail-sleeper grid. The mobile unit comprises a tractor 1, a portal frame 2 mounted on it laterally, consisting of columns 3 supported on the running wheels 5, in the upper parts of which longitudinal beams are fixed, and transverse beams 4 connected to the longitudinal beams. On the beams 4, with the aid of rollers 7, trolleys 6 are installed, to which the lift cylinders 8 are hinged, carrying rails 11. On the extreme beams 4 are installed clamps 12 trucks. Trolleys with grippers and latches form a lattice bending mechanism.

Description

The invention relates to a device for shifting the rail-sleep grid, mainly a rail-sleep grid, on which belt conveyors are installed operating in conditions of open-cast mining.

The purpose of the invention is to increase the reliability of the progressing device by reducing the loads acting in the transverse direction during deformation of the rail-sleeper grid.

FIG. 1 shows the slide rail slide bar, top view; in fig. 2 - the same, front view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a view B in FIG. 3

The slider of the rail grid pattern contains a tractor 1, a portal frame 2 mounted on it laterally, consisting of racks 3 and four transverse beams 4, the ends of which are connected by longitudinal beams of the Rack 3 by means of supporting wheels 5 resting on a ground blade. On beams 4, trolleys 6 are mounted, moving along beams 4 by means of rollers 7. Cylinders 8 for raising the rail-sleeper grid 9 are pivotally suspended from trolleys 6. Rails clamps 11 are mounted on rods 10 of cylinders 8. Cylinders 8 are included in the hydraulic system deployed on tractor 1 and connected to its power supply system. On the extreme beams 4, the fixers of 12 carriages 6 are installed. The last ones installed on the extreme beams 4 are offset from each other. Trolleys 6 with grippers 11 and clamps

12form the bending mechanism of the rail-sleeper grid. Between the last and the last but one beams 4, in the direction of travel of tractor 1, an additional lattice bending mechanism is installed on its frame, which consists of a crank mechanism

13 and guides 14 rigidly mounted on frame 2. In the guides 14, rollers 15 of a trolley 16 are mounted, on which a lever 18 carrying a gripper 19 for a rail is fixed by means of a hinge 17.

When moving the rail-sleeper grid 9, it is necessary to consider the installation period of the portal frame 2 and the period of direct shifting. Before installing the portal frame 2, the drive station must be moved to the shifting step. After that, the portal frame 2 is mounted on the wheels 5, the grippers II and 19 are fixed on the rail and sleeper grid 9, and are lifted by the lifting cylinders 8 to a predetermined height. The end carriages 6 are fixed by latches 12, the middle carriages 6 occupy the position of a deformed rail and sleep grid 9. When the tractor 1 moves along the track, the crank-connecting rod mechanism 13 is turned on and the reciprocating movement of the rail 16, which carries the rail gripper 19, deforms the rail grid 9 when movement of the mechanism 13 forward. Moreover, the time of movement of the trolley 16 by the amount of travel of the curvature-connecting rod mechanism 13 is not less than two times less than the time of movement of the tractor 1 for the same

stroke size. The forward movement of the mechanism is performed at a speed greater than backward. The retraction speed of the mechanism 13 is equal to the speed of the tractor I, which makes it possible to create, as it were, a fixed rail holding point by gripping 19 in the desired position.

In the proposed advancer, by shifting the rail-sleeper grid in a raised position, the maximum bending forces of the rail-sleeper grid are reduced,

the stable linear movement of the advancer is ensured by reducing the dynamic lateral loads due to the large inertia of its mass, as well as an increase in the lateral stability due to the use of a portal frame supported by

on driving wheels.
