(57) Abstract:Usage: in the mine rail transport, in particular in devices for the production of trolleys on rails. The inventive Jack includes a cylinder 1, covering the fixed rack base 4. The cylinder is rigidly attached paw 5, equipped with a fifth 6. The base 4 is installed in the thrust bearing, and the side legs rigidly fixed l-shaped stop 10. 4 Il. The invention relates to a mine rail transport, in particular to a device setting cars on the rails.A device for lifting and setting the path down from the rails of a vehicle, comprising a support base and a lifting body in the form of two jacks with saddles 
The disadvantage of this device is its complexity.Famous Jack containing a rack associated with the base in contact with the thrust bearing, lifting and lowering from the actuator cylinder, on the outer surface of which is rigidly fixed to the load-carrying paw 
The drawback to this Jack inability to supply raised the trolley on the rails due to the inability to reorient derrick paw.The purpose of the invention Reshetko attached to the rack, made with a through hole and mounted in the thrust bearing can be rotated around a vertical axis. The thrust bearing is made with holes, evenly spaced around the circumference, with the possibility of pairing each with a hole in the base when the connection of the latter with the thrust bearing through the lock. Carrying paw made with the l-shaped support for the connection with the hand tool rotation stand with base and provided with a hinge installed on her fifth to the lifted object.In Fig. 1 schematically shows Jack, General view; Fig.2 section a-a in Fig.1; Fig.3 view B in Fig.1; Fig.4 view In Fig.2.The Jack includes a lifting portion made in the form of a lifting and lowering cylinder 1 is placed on the tank 2 for oil and pump (not shown) driven by the arm 3. The cylinder 1 is dressed on a stationary rack, which is provided with a base 4. The cylinder 1 is rigidly attached paw 5, equipped with a fifth 6. The base 4 is installed in the thrust bearing 7, on the surface of which is to reduce friction is applied lubricant. In the thrust bearing 7 is made blind holes 8, which introduces the latch 9, passing through the hole in the base 4. The side legs 5 is rigidly fixed G-obraznye this paw 5 rises trolley. When working on the lift trolley clamp 9 must be in one of the holes to prevent rotation of the Jack. After lifting trolley is not the height of the clamp 9 is withdrawn from the holes 8 and with the mount (short bar), operty blank 10, the rotatable Jack in the thrust bearing 7 (base 4 is rotated in the thrust bearing 7) up until the wheels are on the rails. For lowering the trolley otsenivaetsya screw (not shown) of the Jack. While the oil flows from the cylinder into the reservoir 2 through special channels (not shown). When turning heel Jack 6 allows the trolley to rotate relative to the legs 5 and prevents tilting of the Jack. If the wheels and trucks are far enough removed from the rails, on the formulation of the trolley on the rails produced by the Jack to the desired number of times, i.e., at each position of the Jack, shifting the trolley to the side as much as the flight legs and the angle of rotation of the Jack, limited by the conditions of normal operation of the Jack. JACK containing a rack associated with the base in contact with the thrust bearing, lifting and lowering from the actuator cylinder, on the outer surface of which is rigidly fixed by Gia and installed in the thrust bearing can be rotated around a vertical axis, this heel is made with holes, evenly spaced around the circumference, with the possibility of pairing each with a hole in the base when connecting the latter with the thrust bearing by means of a clamp, and carrying paw made with the l-shaped support for the connection with the hand tool rotation stand with base and provided with a hinge installed on her fifth to the lifted object.
FIELD: railway transport.
SUBSTANCE: invention is related to devices for return of railway cars that went off track, to methods of shoes packaging and to devices for their packaging. Knurling shoe for return of emergency train cars to track is characterised by the fact that on lower side of casing in its middle and back parts multiple cells are arranged that are open from bottom, and cells are created by flanging and partitions of casing. Depth of cells increases from casing back part to its front part. In front part of the latter transverse front and back walls are arranged, in which, accordingly, front and back grooves are arranged for rail head of track. Shoe casing is arranged as cast from metal alloy on the basis of titanium. According to method for packaging of knurling shoes, at first shoes are oriented with their flanges opposite to each other and are installed on cassette base on back parts at the distance from each other that exceeds sum of two heights of front parts of shoes so that center of gravity of every shoe in specified position of shoe is arranged internal circuit of base. Then back parts of shoes are fixed on cassette base, and shoes are inclined to central vertical axis of cassette to contact with horizontal sections of flange, which are located in single vertical plane. Afterwards front part of each shoe is connected to cassette stand. Device for method realisation represents cassette that includes base and stand fixed on base with load eye at its end. Along base perimetre there are at least longitudinal flanges, distance between which is selected as less than width of shoe back part. Height of stand is more than shoe length, thickness of stand is less than width of every aperture arranged in transverse walls of shoe for track rail. Stand has facilities for connection of shoe front parts to it.
EFFECT: as a result, shoe bearing capacity and convenience of its use are increased.

SUBSTANCE: invention relates to railway transport. Proposed device comprises support beam with jacks arranged across the track. Jack rods interact with gripper arranged at coupling head. Working jacks are mounted at moving slides mounted at support beam. To drive said slides at support beam end power hydraulic cylinder is mounted thereat to interact with slides. Slides are articulated by tie-rod Said gripper is composed of thrust beam arranged at coupling one head and bearing clevis arranged around coupling head, its ends coupled with thrust beam.
EFFECT: higher safety, expanded operating performances.

SUBSTANCE: invention relates to railway transport. Proposed device comprises roll-on shoes 1 and pulling device composed by winch 3. Locking device 5 is secured at rail 2. Winch 3 is coupled with locking device 5 by pull rope 6. The latter is passed through set of bypass pulleys 7, 8 to make block and tackle. One bypass pulley 7 is arranged in railway track and connected by rope length with locking device 5. Second bypass pulley 8 is mounted at vehicle 4. Locking device 5 is composed by rail grippers secured at rails 2 with stiffness crossbar 13 arranged there between.
EFFECT: no need in extra tractor.
SUBSTANCE: invention relates to device to lift railway vehicles. Device to lift railway vehicle (3) on rail (5) comprises bearing frame (7) resting at least partially on said rail and lifting element (9) mounted at said bearing frame to lift railway vehicle wheel (11) above rail (5).
