Description

one

The invention relates to railway transport, mainly for the operation of stone-cutting machines in the mining and other industries.

A known mobile track, mainly for the operation of stone-cutting machines in open-pit mining, contains parallel rail lashes consisting of articulated links, a trolley supporting a central pair of these links and 1 j jacks.

The disadvantage is the great complexity and duration of the operation to move the paths when processing the ledges of the quarry.

The purpose of the invention is to increase maneuverability and improve installation conditions.

To achieve this, the trolley was sung as a self-propelled trolley and equipped with a platform rotating in the horizontal plane from the drive of the trolley;

the central pair, the links are fixed on this platform, by means of vertical axes.

The invention is according to drawings: in FIG. 1 shows a general view of a movable rail track; FIG. 2 node 1, in FIG. 3 — a jack, in FIG. 4.- kinematic diagram of a mobile track, in FIG. 5 - platform rotation unit.

The movable rail track comprises a carriage 1 with a platform 2 rotating in a horizontal plane from the drive, parallel rail strips 3 consisting of articulated links 4 connected at the end by a cross link 5.

The central pair is fixedly mounted on the platform, and the outgoing links rest on the jacks 6,

Articulated links are made in the form of loops 7 and have bolt holes 8 for connecting VID of I-slats. Do ("skrats 6 consist of a pin 9, a screw 10, a swivel nut 11c with a handle 12, a support leg 13 with chisels 14 in a guide 15c with notches 16. The logs have figured holes 17 for conveniently gripping the pole during transportation. Moving the trolley 1 is produced from the engine 18 (Fig. 4) through the gearbox. The rotation of the shaft of the engine through the gears 19 and 20 and the electromagnetism of the other couplings 21 is transmitted to the driving wheels 22, which have brakes 23, for example, electromagnetic brake shoes. the necessary rotation of the self-propelled trolley when it moves, the platform 2 rotates around the trolley's axis of the trolley also under the influence of the propulsion motor 18 through the gear teeth 24 (fig. 5), the clutch 25 and the bevel gear 26. The latter engages with fixedly attached to the platform 2 through the axis 27 and the disk 28 with the ring crown 29. The disk 28 with the crown 29 rotates along the rollers 30, the rotation of the turntable 2 relative to the carriage 1, is carried out by pins 31. To do this, the platform 2 is filled through ERSTU, and in frame of the trolley 1 corresponding to the slot (Fig 5) When equipped with one motor bogie (pos. 18) it is powered by a cable 32, and this motor, electro-clutches and electric brakes can be controlled remotely. In order to provide greater rigidity of the track (if required), the rail links are additionally connected by slats installed on the opposite side of each lash. The bolts of these slats extend into the holes 8 and are fastened with nuts through the washers, which leads to a tight connection of the slat with the rails. The operation of the proposed rail is carried out as follows; The self-propelled trolley 1 is fitted with rail links 4 on its platform, and with a stone-cutting machine installed on the central link (shown by the dotted line in Fig. 1), or using a puller to the development section. Then, the jacks 6 are placed on the site, the rail links 4 are pushed apart by turning them around the axes of the loops 7 and placed in the rails of the jacks 15 6. After connecting the condies of the rail lashes with cross-links 5 and aligning them in height, the link is secured with fastening brackets and bolts. After this, the rail track is ready for work and a stone-mining machine begins to move along it. In order to rotate the track by an angle relative to the longitudinal axis of the cart, the plugs 31 are released from the sockets, they are disconnected, the clutches 21 and the electromagnetic clutch 25 are turned on. Then the rotation from the shaft of the electric motor 18 is transmitted through the gears 19, 20 of the gearbox, the bevel gear 26 of the cart 1, toothed crown 29, disk 28 and axis 27 onto platform 2. Platform 2 will rotate until the engine is 18 coezfflHeH with a conical bristle 26. After the necessary rotation, the position of the platform is fixed again with the help of pins 31 platform 2 with jacks 6, the trolley 1 can be raised above the ground and rotated relative to the platform 2. When the cut is made by the stone-cutting mashin, it is necessary to remove the jacks 6, the cross link 5 and the strips 33, and then fold the rail links 4 onto the platform 2 and move the trolley to the desired distance. In this case, the rotation of the platform) we are performed as described above. The trolley can be controlled remotely by moving the rail track by alternately switching on the right or left electromagnetic clutch 21 and the corresponding brakes 23. This will turn the cart to the right or left relative to the direction of the received movement. Both clutches 21 are turned on for moving the truck forwards or backwards. Both brakes 23 are turned off. Formula of invention A mobile track, mainly for the operation of 56990 stone-cutting machines in open-pit mining, containing parallel rail lashes consisting of articulated links, a trolley supporting a central rod these links and jacks, characterized in that, in order to improve maneuvering and improve the installation conditions, the trolley is self-propelled and equipped with a platform x-,. 1. / Ly of V I 1mLZ 4 pivoting in a horizontal plane; from the drive of a trolley, with the central pair of links fixed on this platform by means of vertical axes.
