Description

The existing input semaphores, the wings of which are driven by wire ropes by means of lever machines installed near the building where the station duty officer is located, and in other cases, depending on the operation of the station near the switch box of the first along the train of the switch post, they do not give a full guarantee to avoid taking a train going on a stage after another, on the path taken by the previous train, as the station duty officers sometimes forget to close the semaphore personally or give about that the disposal of the switchman, and verify that the last of the thrust stress. To remedy these shortcomings and serves the proposed device.

In FIG. 1 and 2 depict the device in two projections; FIG. 3 - adaptation scheme.

The proposed fixture consists of a rotary axle / 7 lever / with a tapered roller 2, two cranes 3 and 4, a cylinder 5 with a piston 6-8 for lifting the lever / tubes 9, 10, 73, 14 and 75.

The operation of this device is as follows. When the semaphore is closed, the pedal is in an idle position, i.e., a conical ro (3951

VIC 2 is on a level with a rail head, spring 7 of cylinder 5 is decompressed piston 8 is in the lower position; valve 3 is in the open position, and valve 4 is in the closed position. There is no pressure in semaphore and cylinder pipes 9-10.

When the semaphore station opens, the liquid will pass from station 75 through valve 4 to the semaphore along pipe P and branch pipe 10 to the pedal cylinder. By the pressure of the fluid in the cylinder, the piston will work and lift roller 2 of lever T with piston 8-6 by 30 mm. pull out the rail heads. The device is thus brought into operation. The semaphore is open. By pushing the strap of the moving unit of the train onto the tapered roller 2, both spools of cranes #, 3 are set in motion with the help of lever 7. Lever 7, turning clockwise on axis 77 clockwise, presses the handle 18 on the cylindrical roller 18 with its lower tail end the first spool 5 and pushes it to the right; Rotating counterclockwise, lever 7 is idling, i.e., when the train leaves the station.

By moving the handle 12 to the right, the axes of the spools of both taps are turned by means of the pull 76, which is achieved; a) the overlap in the right valve 3 of the pipe leading the liquid from the station to the semaphore, b) connecting the semaphore pipe through one valve to the second valve pipe 4, c) releasing the liquid from the semaphore at the station using a drain pipe / J.

With the release of fluid from the semaphore tube, which leads the semaphore wing to the normal (closed) position, the fluid from the cylinder enters the drain tube. The spring 7 of the cylinder 5 brings the piston to the lower position, resulting in the lowering of the piston -6 carrying the lever / and the taper roller 2.

Thus, the tapered roller is brought to its normal position and the semaphore is closed. The axes of both valve spools remain rotated, since the frictional force from the fluid pressure in the spool is greater than the force of spring 7. While the lever / and semaphore is actually closed, the semaphore control lever 3 of the station apparatus remains in the same position. To bring all the spools of valves 3 and 4 to the normal position, as well as the handles of the control apparatus (at the station), it is necessary to close the semaphore lever. After closing the lever, the device is again ready to work.

The subject matter of the invention.

A hydraulic device for controlling the travel signals by the train itself, consisting of a rotary pedal acting on an overflow valve serving as a guide for the pressurized fluid to the serviced route signal from the latter to the drain pipe, characterized in that the drain pipe is equipped with a crane 4 articulated J6 with the overflow valve J to prevent, in case of clogging of a part / 5 of the drain pipe, lift the valve 3 of the valve 3 by the pressure of the liquid and thereby the penetration of the liquid to luzhivaemomu track signals, despite the closed position of the valve 3 to the certificate of authorship LE Tatarova 39204 A2
