SU22097A1 - Arrow switch device for direct transfer of track arrows from a steam locomotive - Google Patents

Description

The present invention relates to a switch device for directly transferring track arrows from a steam locomotive using ropes connecting the arrow strings to a translation mechanism located on the track and interacting with a lever mounted on the steam locomotive, and aims to increase the motion intensity of the steam locomotives. The switch-set switch is mounted on the sleeper between the rails and is connected to the arrows via cable transfer levers. When the engine moves against the arrows, the driver turns the handle to the desired branch; when moving in the opposite direction, the arrows are automatically shifted. The transfer device communicates with the control handle through the crutches that descend to it from the locomotive.

In FIG. 1 shows a front view of a switch device with a partial section; FIG. 2nd plan.

In frame 1, axle 2 and cam 3 of the lock boxes are reinforced: the bottom one is 4 and the top one is 5. The axle 2 is fitted with: sleeve 6 with rollers 7 and 8, sleeve 9 with rollers 10 and 11, and washer separating sleeve 12. 12 -14 roller and

the latch 15 with the roller 16, stroke t, respectively, in the grooves of the lower box 4 and the upper 5. The springs 17 and IS rest against the latches 13 and 15, the purpose of which is to place the latches in their original position when their rollers come off the cam 3. On the fingers 21 and 22 are worn, respectively, levers 19 and 20, as well as traction earrings 23 and 24.

When the roller of the movable crutch 25 is lowered and moves in the direction of the arrow, it hooks the lever 20, the inner arm of which rests on the roller 7 of the bush 6, the other roller 8 of which rests on the latch 15. The boxes turn around and 2 and the earring 23 tons there is no rope attached to it until roller IS 16 of the latch climbs cam 3 and releases bushing b. When the locomotive reverses, the crutches engage the levers 19 and 20, but do not rotate the boxes. The dotted line of the lever 20 shows its position when the crutch 25 is moving in the opposite direction. The dotted line O of the lever 19 shows its initial position, and the dotted a-position when the movement is reverse is the crutch 26. The levers 19 and 20 are set in the primary position by springs located

on both sides of each lever. The springs are put on the studs 27 fixed in the levers and the other ends on the studs 28 inserted into the boxes 4 and 5. The hole in the lower lock box through which the cam passes is covered by the flap 29. The doors - the flaps 30 cover the holes through which the exit t the inner shoulders of the levers 19 and 20 when they are retracted to the extreme position.

The subject matter of the invention.

An arrow switch device for directly transferring track arrows from a locomotive using ropes connecting the arrow strap to a translation mechanism located in the path and communicating with a lever mounted on the locomotive, characterized by the use of a release device consisting of latches 13 and 15 freely inserted the grooves of the boxes 4 and 5 of the mechanism, supported by the springs 17 and 18 and designed in one of its positions, abut against the rollers of the sleeves 6 which are freely mounted on the fixed axis 2 and 6 9 and thereby linking the levers 19 and 20 with the said boxes 4 and 5, and at a different position corresponding to the rotation of these boxes at a certain angle under the action of the levers 19 and 20, move away from the sleeves 9 and 6 and fall into the cutouts of the cam 3, to disengage the inner ends of the levers 19 and 20 from engaging with the boxes, in order to allow the vehicle to move freely in the opposite direction.
