A unit of rolling stock can move on a tow truck, either resting its wheels on stops, or resting the axle of the wheel pair or an element of the vehicle bogie on a stand installed on a platform on the top of the beams. 1 salary f-ly, 4 ill.

Description

The utility model relates to rail vehicles, in particular to rollers and other means for moving and transporting railway rolling stock along the tracks.

A device for moving rail vehicles with a jammed wheel pair is known from the prior art (patent RU98382), which contains carriages with rollers and stops for the wheels of the wheel pair installed under each wheel of the jammed wheel pair, and a mechanism for mutual movement of the carriages. In this case, the mechanism for the mutual movement of the carriages and the carriages themselves are installed between a pair of load-bearing cheeks. The cheeks have guide grooves and locking holes for securing the carriages and the mechanism for mutual movement of the carriages. The carriages are equipped with stops and base pins. In this case, one of the carriages, with the grooves of its basing fingers, is movably installed in the guide grooves of the bearing cheeks. The second carriage with its base pins is mounted motionless in the locking holes of the bearing jaws. The mechanism for mutual movement of the carriages is made in the form of a lead screw, the drive end of which is located in the threaded hole of the support, fixedly fixed between the bearing cheeks. The end of the working end of the lead screw interacts with the movable carriage.

The disadvantages of the device are: the use of open lead screws in a dirty environment; the use of stops made without taking into account wear on the tread surface of the wheels of a jammed wheelset; limited technical capabilities; insufficient installation efficiency.

The closest to the claimed tow truck in terms of the problem to be solved and the result achieved is the emergency recovery trolley (patent RU214415), consisting of four wheel units and four support bushings, connected by means of coupling bolts in pairs along the axis of the wheel pair, axles and with longitudinal beams. The longitudinal beams of the bogie have holes for installing support bushings with the possibility of supporting wheels of different diameters on them.

The disadvantages of the cart are: the use of tie bolts and blind threaded holes in dirty environments; the support bushings are made without taking into account wear on the tread surface of the wheels of the wheelset; the use of small parts that can be lost during field installation.

The objective of the claimed utility model is to create a device for quickly moving a unit of rolling stock with a faulty wheel pair along a rail track, with the ability to pass curved sections of a small radius track and switch crossings. The device must be conveniently and quickly mounted under a faulty wheelset, as well as with additional devices - under the axis of the wheelset when the wheel rim is displaced, or under the bogie of the moving unit when the axis of the wheelset is broken. In this case, the device must be mounted under a wheel pair of a certain standard size, with wheels having different diameters and rolling surface profiles. The device should not have elements that can be lost, broken, or rendered inoperable in the field.

The task at hand, for quickly removing a faulty unit of rolling stock from a haul, is solved by the fact that the device is made in the form of a compact tow truck, which contains four wheel blocks and four stops, connected into a single structure directly under the suspended wheel pair using four longitudinal beams and two transverse axes. The stops, made in the form of axles, have a plate in the center with positions for supporting wheels of a certain standard size. A unit of rolling stock can move on a tow truck, either resting its wheels on stops, or resting the axle of the wheel pair or an element of the vehicle bogie on a stand installed on a platform on the top of the beams. The axle of the wheel blocks, made in the form of a bushing, has annular grooves at the protruding ends. The beams have two pairs of holes; stops are installed in one, and the beams are hung on the annular grooves of the wheel axles using the second. A rolling surface is formed on the wheels of the wheel blocks, which is limited on one side by a ridge and on the other by a flat protrusion, which serves for the smooth passage of turnouts. To reduce contact stresses when moving along a rail track, the rolling surface has a slope equal to the standard slope of the rails.

Technical result: installation time has been reduced and the ergonomics have been improved; technical capabilities have been expanded; The reliability of the quick removal of a unit of rolling stock from the stage with any damage to the wheel pair has been increased.

The figures show: a tow truck (1), a stand (2), a wheel pair with an offset wheel rim (3), a wheel block (4), a stop (5), a beam (6), a transverse axle (7), an annular groove (8), platform (9), axle (10), plate (11), position for car wheels (12), position for diesel locomotive wheels (13), position for electric locomotive wheels (14), rolling surface (15), ridge (16), flat protrusion (17).
