Abstract

The invention relates to equipment for repairing rolling stock of railways. The purpose of the invention is to expand the functionality. The device contains a lifting-turning mechanism, made in the form of a screw pair, the cargo screw 5 of which is hollow, and the nut 6 consists of two parts: threaded and non-threaded, connected by a bearing 7. On the threaded part of the nut 6 are pivotally mounted levers 9, 10 having the ability to rotate horizontally and freely slide along the limiters 12 of the movement of the levers installed in the walls of the rod, while the nut is made with the stops 11 arranged at an angle to the axis of the screw equal to the angle of deflection of the lever at the maximum th removal of the free end of the screw axis. 3 il.

The invention relates to equipment for repairing rolling stock of railways.

The purpose of the invention is to expand the functionality. I FIG. 1 shows the device, I general view; in fig. 2 is a view A of FIG. 1 in FIG. 3 - node I in FIG. 1 (horizontal, horizontal limiter, section). I The device B contains at least two intersecting tracks 1 and 2, a floor pushing conveyor 3, with a mock, located at the intersection of tracks 1 and 2, and there is a lifting-turning mechanism in the form of a screw pair, cargo screw

5 of which is hollow, and the nut 6 is in two parts, threaded and non-threaded, connected by a bearing 7. On the i-threaded part of the nut 6, levers 9 and 10 and I are fixed to the hinges of jpax 8 .11. Moreover, the stops 11 are mounted to the axis of the screw 5 at an angle equal to the angle of deflection of the lever at the maximum removal of its free end from the same axis.

:. In the walls of the prong k, in its upper part, there are horizontal stoppers 12 for moving the levers, made with -shaped cuts, having oval surfaces A, on which the arms 9 and 10 freely slide along the vertical direction, having

Slot slots 13. A cargo screw 5, mounted in support AND, is driven by a 15-lift drive. Drive 5 passes through screw cavity 5

The levers 9, together with the trolley, are lowered and the trolley becomes on track 2. The drive 15 is disconnected, then the special mechanism of the truck shaft 16, having the drive 17, is turned 40 to the repair position. After

that In the upper part of the drive shaft l6j, for example, at its end, a rocker 18 is installed.

The device works as follows.

In the initial position, the nut b of the screw pair with the levers 9 and 10 is in the lower position (in Fig. 1 it is depicted with a dotted line). The carriage of the car conveyed by conveyor 3 along the rail route 1 to the intersection with the rail track 2. The lift drive T5, which rotates, the load screw 5 is turned on. The nut b then lifts along the load screw, as the levers 9 and 10 by the arms 12 limiters prevent its rotation. The levers 9 are then freely slid over the oval surface A of the stops 12

This includes reversing the actuator 17, turning the levers 9 to the initial position, turning off the actuator 17 and engaging the reversing actuator 15 to lower the levers 9, which fold down along the movement limiters 12 of the levers. Next, the process is repeated in a similar way.

The shape of the invention The device for lifting and turning the vehicle components, in particular carriages, the secondary base and the lifting drive installed on it in the form of a screw pair and the turning drive, which is different in that it is equipped with a drive shaft , short

moving levers. When the angle between the lever 9 and the axis of the screw is equal to the angle of deflection of the stops 11 with respect to the same axis, then the levers 9 stop sliding along the limiters 12 of the movement of the levers, rest on the stops 11 and the levers 9 engage with the rocker 18 (the rocker 18 enters slit 13 levers).

In this position, the levers 9 are ready (the distance between the free ends of the levers is equal to the center distance of the carriages) for receiving the carts. With further rotation of the cargo screw 5, the levers are brought to the axles of the carriages and lift the cart to the height of the exit from the engagement of the flange of the wheels with the rail head and create a guaranteed clearance for turning. After that, turn off the drive 15 and turn on the drive 17 of rotation, which turns the drive shaft. The beam 18, located on the drive shaft 1b, is rotated together with this shaft. Since the rocker 18 is engaged with the levers 9, it rotates these levers, which are located on the threaded part of the nut b, together with the trolley, at the required angle, onto the rail track 2.

Then turn on the drive 17 reversibly - the drive 15 of the rotation of the cargo wine5.

The levers 9, together with the trolley, are lowered and the trolley is placed on the rail track 2. The drive 15 is disconnected, then the trolley is transferred to the repair position using special mechanisms. After

This includes reversing the actuator 17, turning the levers 9 to the initial position, turning off the actuator 17 and engaging the reversing actuator 15 to lower the levers 9, which fold down along the movement limiters 12 of the levers. Next, the process is repeated in a similar way.

The shape of the invention The device for lifting and turning the vehicle components, in particular carriages, the secondary base and the lifting drive installed on it in the form of a screw pair and the turning drive, which is different in that it is equipped with a drive shaft , fixedly mounted on the upper end of the drive shaft, levers pivotally mounted on the screw pair nut can be rotated in the horizontal plane when the nut is in the upper position at the end of the weights mounted on the base of the limiter movement of the levers installed with the possibility
