Description

The utility model relates to the field of railway transport, and in particular to machines for heating rail lashes in order to enter them into the optimum temperature regime and subsequent fixing.

A known machine for heating rail lashes (see, for example, US patent No. 5.299.504 in class E01B 29/00), equipped with inductors lowered onto rail lashes for heating them. The machine allows you to enter rail lashes in the optimal temperature regime.

The disadvantages of the known machine can be attributed to the fact that it allows heating only loose lashes lying on the sleepers. For free extension of rail lashes, they must be mounted on supports with a low coefficient of friction, otherwise, lashes, after their fastening, may form sections with an uneven distribution of stresses.

The aim of the development is to create such a machine for heating rail lashes, the design of which would allow it to produce rail lashes in a suspended state. This would make it possible for new lashes to extend freely during heating over a sufficiently long section and, accordingly, would reduce the likelihood of formation in the lashes, after they are fixed, of sections with an uneven distribution of stresses.

For this, the machine for heating rail lashes is equipped with a mechanism for gripping and moving rail lashes 1. The mechanism for gripping and moving rail lashes 1 can be made comprising front and rear pairs of bogies 2 with roller grippers 3, where

each pair of trolleys is connected by a transverse beam 4, and each trolley 2, with two roller grips 3 and guide rollers 5 mounted on it, is pivotally suspended from the transverse beam 4, which, in turn, is pivotally suspended on the lifting cylinders 6 and connected to the frame of the machine through the central telescopic guide 7, which transfers to the transverse beam 4 the forces of the hydraulic cylinders of lateral displacement 8. The induction installation can be performed with two inductor units 9, each of which is I have a construction in the form of a suspension suspended from the gripping and moving mechanism of rail lashes, a supporting frame with sections of inductors installed on it, each of which consists of two leaf semi-inductors mounted on a supporting frame with the possibility of rotation around axes parallel to the longitudinal axis of the rail and equipped with tracking rollers. Tracking rollers mounted on the semi-inductors make it possible to maintain a constant gap between the half-inductor and the surface of the rail lash in the working position. Machine designs are also possible when the front and rear bogies of the gripping and moving mechanism of one rail are connected to each other through an inductor block suspended from them, and also when it is equipped with a crane unit 10 and is equipped with a platform 11 for transporting the stacker carriage and the track parser 12, as well as the carts of the parser path 13 and the portal crane 14.

on Fig is a diagram of a complex for laying lashes (with welding on the composition and heating the lashes inside the rut).

The operation of the machine for heating rail lashes as part of a braiding complex containing, for example, a composition for transporting lashes, as well as a track rail welding machine for welding lashes up to a block length in the composition, can be carried out as follows.

Upon arrival of the complex to the work site, the initial joints are undocked and the loose ends of the replaced lashes or inventory rails are shifted into the gauge by 540 mm between the longitudinal axes of the rails (symmetrical to the track axis). Next, the first two lashes to be unloaded from the locking devices of the whip-laying complex are released and shoes are placed on their ends. With the help of a pull-up device, the liberated lashes along the grooves of the guide device, through the anti-edge device, along the support rollers of the rail welding machine and the end platform, are laid inside the track.

Moving behind the train, from which the lashes are unloaded inside the gauge, the machine for heating rail lashes drives up to the place where the lashes start and occupies a position above them so that the lashes can be gripped and lifted using the lifting centering mechanism 1. It should be noted that reliable capture of rail lashes by the lifting and centering mechanism of the machine for heating rail lashes, the initial sections of the lashes, when unloaded inside the gauge, can be stacked on bars 15 installed between the sleepers, level in rhnego bases are located above the upper base sleeper middle section and the distance between which is longer than the inductor unit. Further, from the platform 11, the machines for heating rail lashes with a crane 10 are removed and installed in the following sequence: a trolley 13, a portal crane 14, a stacking trolley 12, as well as other additional equipment (cable, rod, etc.). The parser truck 13 and the portal crane 14 are moved beyond the initial junction of the inventory rails. Then the trolley with the bar

connects to a rail lash heating machine. The lifting-centering mechanism 1 captures and lifts the end sections of the rail lashes laid inside the track. The inductors 9 covering the lashes are turned on and the rail lash heating machine starts to follow the train, while the ends of the new heated lashes are sent to the vertical rollers of the stacker 12 and then to the pads to the original joint, where after removing the shoes they are joined with the rails lying in the path leveling span. The gantry crane 14 and the trolley 13 are moved to the newly laid lashes. The portal faucet 14 stops above the ends of the inventory rails shifted inwardly of the track, and with its help, their ends are hung out and tucked into a pick-up trolley 13, which is then connected by a cable to the stacking trolley 12. Then, the portal faucet 14 is removed to the platform of the machine for heating rail lashes .

When the machine moves to heat rail lashes after the train, the old lashes or inventory rails are shifted into the track and new lashes are laid on the lining. Traffic monitors track and guide the lashes onto the lining and at the same time fix the inventory rails in the middle of the track with crutches.

Thus, the machine for heating rail lashes provides continuous heating in the suspended state of two welded lashes up to a block length or more, laid inside the gauge, which allows to achieve the optimum temperature for fixing the lashes and allows the lashes to extend much more freely during heating than in the case of them heating in transit. Simultaneously with the heating of the lashes lying inside the rut, the machine allows laying heated lashes from the rut on lining with the replacement of replaceable lashes.
