Description

one

The invention relates to means of rail transport and can be used in underground mining with electric locomotive haulage.

The purpose of the invention is to reduce the energy consumption per ton and braking by adjusting the axial load.

FIG. 1 shows a mine rail transport system, a general view; in fig. 2 - control circuit.

The mine rail transport system consists of a running gear 1, body 2, traverse 3 with rollers, which are jointly connected to the body with a hydraulic cylinder 4 lifting the traverse, which guides 5, reinforced under the roof of the mountain. The piston cavity of the hydraulic cylinder 4 is connected to the cavities of the hydraulic cylinder 6 of the coupling device 7 by means of a pipeline, and to the hydraulic accumulator 8 and the pump 9

by means of spools 10 and m. t

The system of mine rail transport works as follows.

When the locomotive moves in the pull-out mode along a section of the rail track with an overestimated profile, the force arising in the coupling device 7 moves the piston of the hydraulic cylinder 6 to the right and the fluid from the rod end of this hydraulic cylinder passes through the pipeline through a non-return valve to the piston

cavity g: idrocylinder 4 lifting traverse 3.

Traverse 3 is raised and pressed by rollers to guide 5.

5 The occurrence of a reaction between the rollers and the guide leads to an increase in the normal force between the wheels and the rails, and consequently, the force of drag (braking).

0 Since the force on the coupling device is variable due to movement along the variable profile of the track, the force of the traverse 3 is automatically monitored, and therefore

5 and the power of gi.

When operating in the braking mode, when the locomotive is in the tail of the train, the system works in a similar way to the traction mode.

0 When braking, when the locomotive is: in the head of the composition, the force on the coupling device M 7 moves the piston of the hydraulic cylinder 6 to the left, while the fluid from the piston cavity

5 of the hydraulic cylinder acts on the spool 10, which connects the cavity of the hydraulic actuator 8 to the piston cavity of the hydraulic cylinder 6 lifting the crosshead 3.

0 The invention allows, by adjusting the force of pressing the traverse, to optimize the resistance to the movement of the locomotive and to reduce the energy costs of traction and braking.
