under the head j) e,: ibca. The cylinder of the i-hydraulic press is installed in the lower part of the device on the thread for the preliminary clamping of the rail in this part.

FIG. 1 shows a side view of the upper part of the device with a partial incision; in fig. 2 - view of the upper part from the end (partly in section); in fig. 3 is a plan view of the lower part with a section through a hydraulic press; in fig. 4 is a section along AA in FIG. 3; in fig. 5 lever the jack in the cut.

The device consists of two main parts: the lower (Fig. 3) and the upper (Fig. 1 and 2). The lower part is made in the form of a flat triangular welded frame. On the sides of the I, 2 frames at the side 3 forming the base of the triangle, there are two unors for the bottom of the rail. In the middle part of the base of the triangular frame there is a nut 5, which includes a screw 6 carrying the cutter holder 7. On the latter, two spring-loaded rotary cutters 8 are installed to form a notch on the upper and lower surfaces of the rail foot.

Rubber rollers 9 with a handwheel 10 can be used as a spring element for the cutters. At the top of the triangular frame there is a hydraulic press for clamping the rail and forcing the rail horizontally. Cylindrical housing / The press is welded to the sides of the frame. In the housing, a hydraulic cylinder 12 is mounted on the thread with two steps for the piston 13, which receives the pressure of the liquid medium and the pressure plunger 14. The piston and plunger are ground to the cylinder. At the end of the hydraulic cylinder 12, one half of the 15-cam clutch is fitted; The second half of this coupling 16 is movably mounted on the hexagonal rod 17 of the injection plunger. The plunger has a thread on the outer surface that is screwed into the thread on the wall of the pressure stage of the cylinder.

The piston 13, which receives the pressure of the liquid medium, has a slot on the end protruding from the cylinder end for the rail bottom. This piston is provided with a slider / V to prevent it from rotating in the cylinder. Inside the piston a channel is bored outward with a safety valve installed in it (it is shown on the drawing).

The case of the lower part of the device is equipped with a handle 19 for reloading. The body part of the device is made in the form of a welded frame 20, at the ends of which there are two supports 21 with twin grippers, and in a similar part a hydraulic press 22 for creating a vertical load on the rail head. The supports of the upper part of the device are U-shaped and in the working section, they cover the rail from above. In the body of the supports, inclined grooves are formed in which the positioned slides 23, set under the rail head. Sliders for moving them have rings 24.

Porschen 25 hydraulic press is equipped with a pointed punch and installed in the cylinder with the possibility of only axial movement. The press cylinder is mounted in the frame of the upper part of the device on the screw 26, in order to rearrange the cylinder in height. The screw has a handle 27 for pre-mounting the cylinder. Cylinder 28 is pressurized to the press cylinder; A safety valve 29 is screwed into the press cylinder body.

The plunger 30 of the blower is mounted on its thread in its cylinder and is moved therein by screwing in or unscrewing as the shank 31 of the plunger 31 protrudes outwardly.

As a working medium for hydraulic presses, a thick graphite paste-like lubricant is used.

To lift the rails, reposition the press cylinders and move the plungers, a lever jack is designed, made in the form of a pipe 32, at one end of which a rack jack 33 is located. The other end of the pipe is designed inside

the shape of a wrench 34. H; K-MI1 1Y wrench with a ratchet head; the key handle to create a large force is inserted into the snarring tube of the jack jack.

The lifting paw 36 of the jack is welded to the end of the pipe, and inside the latter there is a tubular segment 37 with a base plate 38 at the outwardly projecting end; the other end of the tubular segment is connected to the toothed rack 39. On the pipe is mounted a doggie 40 and a gear gear 41 interacting with the teeth of the slats.

The trimming or fracture of the rails is performed by two people who perform this work in the following order.

The first number brings Lan to the jack lever under the rail and, acting with a wrench, rotates the gear, while raising the rail or section of the path. In elevated condition, the load is held by the dog. The second number places the lower part of the trimming device under the rail, after which the first number jerks the jack away to the top, the outer pipe and the rail fall onto the BOTTOM part of the trimming device.

After the rail is under the base on the bottom of the trimmer, the first number, acting with a wrench, rotates the shank of the lower pressure piston.

In this case, the cam half coupling must be preliminarily pushed forward along the hexagonal rod of the delivery shaft, before engaging with the half coupling of the hydraulic cylinder, which causes the cylinder to rotate in the nut of the press body and advance the cylinder forward until the rail foot enters the slot of the press.

Further rotation of the cylinder will cause movement of the rail and the introduction of the opposite side of the sole under the stops on the frame of the lower part of the device. After that, the cam clutch is separated and the pumping piston shaft continues to rotate. Screwing into the cylinder, the piston increases the pressure of the liquid in the press cylinder and displaces its piston, which will strongly clamp the rail at the bottom of the trimmer.

The second number at this time sets the top of the rail head. In this case, the sliders, under the influence of the weight of the upper part, are moved apart to the sides, and then they are manually moved forward to the front and down.

After lowering the sliders, the second died rotates the vertical screw by the handle until the sliders grab the rail head from underneath. Then the first number tightens the same screw. In this case, the hydraulic press piston and sliders are pressed tightly against the rail head, respectively, from above and below.

The second number at this time handwheel rotates the screw, which moves the tool holder with cutters to cut the rail foot, forward cutters up to the stop against the edge of the base rail. Then, by means of acting on the screw of the wrench inserted into the pipe of the lever of the wrench, an incision is made at the foot of the rail. When advancing the cutters forward, they cut the metal from the top and bottom of the foot in the direction of the future crack development, i.e. in the direction perpendicular to the rail axis. As the rail ram moves forward and is inserted into the metal, the cutters having a specially selected shape gradually open up and down and, when the pads reach the bottom of the rail and press into it, the cutters stop. At this point, they manage to open up so much that their front cutting ends come out of the thickened base.

After the notch has been formed, the first number puts a wrench on the faceted end of the pressure plunger protruding from the cylinder and creates the necessary pressure in the press cylinder, and consequently, the maximum vertical load on the rail head. Then moving the pressure

The plunger on the bottom of the trimming device increases the pressure.

in the press of this part to the value that provides the rail break.
