Description

one

The invention relates to the mechanization of road work in the construction and repair of railways.

 A device for shifting and liquefying a rail-tie grid is known, comprising a support frame attached to the frame of the track machine, double-acting hydraulic cylinders and roller blocks mounted on the support frame l3.

It is also known a device for l) calibrating the rail grille in plan, comprising a support frame hinged on the frame of the track machine, a double acting hydraulic cylinder fixed on the support frame by means of a pin, and roller blocks, one of which is rigidly fixed on one of the rods of the said hydraulic cylinder pj.

The drawback of the devices is that they do not ensure the work of the track machines when hanging the rail and sleeper grid at a height of 400 mm and when operating in belts with increased longitudinal forces.

 The aim of the invention is to increase the hope: -; nosti operation of the device.

For dos;; And::.: - Well this goal it. additionally equipped with a support frame hinged on the frame of the track rail, a double-acting hydraulic cylinder fixed to the support frame by the pin, and roller 1 and blocks, one of which is rigidly fixed on one of the additional cylinder rods, and roller blocks on the second rods of the above hydraulic cylinders are fixed articulated

Each roller block includes two vertical rollers and a horizontal roller placed between them, and the supporting frames are fixed at an angle to the rail threads.

FIG. 1 shows a device for (Fixing a rail-sleeper grill, front view; on Fig. 2, the same, side view.

The device for fixing the rail of the dump grid comprises the frame 1 of the track machine, connected through hinges 2 to rigid transverse support frames 3. The lower parts of these frames are divided by the value L,

5 which may change during the operation of the machine. The pins 4 are mounted on the frame.h 3 at an angle | b.

In this case, the angle value is chosen such that the fasteners are parallel to the longitudinal axis of the machine frame at the moment of action of maximum longitudinal compressive forces in the rails. On the pins 4, the hydraulic cylinders 5 are double-fixed, the rotation of which is limited by stops at the distortions of the track or the discharge of electromagnets from one of the rail awv tvs. On one side of the hydraulic cylinders 5 on the rods 7, roller blocks are rigidly fixed, and the other is hinged. The roller block consists of vertical 8 and horizontal 9 rollers. The device works as follows. During machine operation, the fixing of the rail grating in the plate is not carried out by roller blocks. The synchronization of the movement of the rods 7 is achieved by connecting the corresponding cavities of the hydraulic cylinders 5. When the rail-and-sleeper grid is hung with electromagnets, the hydraulic cylinders 5 move apart from each other (they move apart with increasing distance L along the rails on the rollers 8. This feature of the device is important when the machine is operated in areas where longitudinal tensile forces, i.e., when, there is a temperature limit on the lower limit. When lowering or accidentally resetting the rail and fins of the hydrocyl Indra 5 come closer (distance U decreases). In this case, the device automatically fits in a vertical plane (rolled vertical rollers 8 along the path) under its own weight without losing contact with the rail and rail grid. This sAflieKT can also be strengthened by positioning the mountain sunshade rollers 9 at an angle to the longitudinal axis of the rails and an additional pressing of the device vertically with hydraulic cylinders, which simultaneously serve to bring the device into transport position. Thus, the device makes it possible to increase the length of the gripping of the rail-optical grid and the number of points of contact of the machine with it. The device for fixing the rail-sleeper grid in the plan, comprising a support frame, hinged to the frame of the track machine, a double-acting hydraulic cylinder mounted on the support frame by means of a pin, and roller blocks, one of which is rigidly fixed on one of the rods of the above-mentioned hydraulic cylinder, is distinguished by so that, in order to increase the reliability of work, it is equipped with an additional support frame, hinged on the frame of the track machine, a double acting hydraulic cylinder fixed on the support frame pivots, and roller blocks, one of which is rigidly fixed to one of the additional cylinder rods, and roller blocks on the second rods of the above-mentioned hydraulic cylinders are hinged, each roller block includes two vertical rollers and a horizontal roller placed between them, and supporting the frames are fixed at an angle to the rail yarns.
