Description

PisBecTHW devices for pneumatic remote control of hoppers of the Zuluvagon type hopper, equipped with a pneumatic splitter, the piston of which is connected to the shaft that carries the lever rocker arms for the manholes. Such devices use a golden air distributor, a control valve and a mechanism for automatically locking the lever system when the hatches are closed: And releasing this system to open the hatches.

A significant disadvantage of such devices is the unreliability of their operation and the relatively large complexity of constructive design.

The predictable device is free from the indicated disadvantages. The essence of the invention consists in the fact that the spool air distributor, operating at two pressures, is made in the form of a cylinder with zoletikol; and a spring, and the locking mechanism is in the form of a slider rigidly connected (With a curtain and supplied when the hatches are closed, the lower arm of the lever system. The device uses a rotary-type pneumatic motor with a reciprocating-circular piston; movements. .

FIG. J is a perspective view of a general view of the device; in fig. 2 is a diagram of the pneumatic part of the device on the gondola; in fig. 3-the same on the locomotive.

The device is mounted inside the splitter in the middle of the gondola. On the longitudinal beams / frames by means of short crossbars 2, a pneumatic motor 3 of a rotary type is mounted, the piston 4 of which performs reciprocating circular motions. The shaft 5 of the engine is connected to the shaft 6 carrying the rocker arms 7, connected to the lever system 8 for the hatches. On the longitudinal beams of the gondola frame coaxially with the pneumatic engine shaft is mounted a spool valve 9 that operates at two pressures, for example, 4.5 and 6 atm. O / N 117747-2 -

The air distributor's sprue barrel is loaded with a spring 10 and is rigidly connected to a slider 11, designed to stop the lever control system of the hatches in the closed position of the latter. The air line 12 is connected via pipe 14 via valve 14 to the air distributor cylinder 9, and the latter two air lines / 5 and 16 are connected to the working cavities of the air motor cylinder 3. A four-way valve 17 is installed on the locomotive (steam locomotive, locomotive or electric locomotive); an air reservoir, such as an electric locomotive receiver, through a shut-off valve 18, air is supplied by two pipelines 19 and 20. Valves 21 and 22 of different maximum pressure are installed on these pipelines, for example, valve 21 at 4.5 atm, and on the other, valve 22 at 6 atm. Depending on the position of the four-way valve, air pressure of 4.5 or 6 atm enters the air line of the device. By the same valve, the main line can be disconnected from the air source or the common air with the atmosphere.

The device operates as follows. To open the hatches, the four-way valve J7 is set to the opening and air position through the open shut-off valve 18, the passage of the maximum pressure valve 21 and the four-way valve enters the line 12. From the line through the valve 14, air enters the air distributor piston 9. Overcoming the force of the spring 10 air distributor and stirred and the valve, the air enters one of the cavities of the air motor to open the hatches.

The air distributor spool, connected by rods 23 with the slider 11, during its movement leads the slider out from under the lever 8.

After opening the hatches, the locomotive driver clears the lever of the hatcher control systems, sets the valve 17 to the position of air release to the atmosphere from the air distributor engine and the main line.

The air diffuser under the action of the spring returns the slider to its original position.

To close the hatches, the four-way valve 17 is set to the "closing" position. Air through valve 22 of maximum pressure (6 atm), valve 17 and line 12 falls under the piston of the air distributor, moves the valve of the latter to a position that fills the same cavity of the engine as in the "opening" position, after which the valve is mixed to the position in which the other cavity of the engine is filled. The air from the first cavity of the engine through the holes in the spool enters the atmosphere.

The engine shaft, turning in the opposite direction, closes the hatches. After the hatches are closed, the four-way valve 17 is set to release air to the atmosphere. Under the action of the spring, the distributor valve returns the slider to its original position and locks the lever control system of the hatches.

The device serves to simultaneously open or close all cars of the train, which are connected to each other and to the locomotive by intercarriage sleeves. Selective remote control of the hatches of individual cars is also permitted by disconnecting from the highway non-unloading gondolas.

The proposed device provides for the mechanization of unloading hopper gondola cars, without requiring rework.
