SU30712A1 - Device for detecting closed inter-car valves of the main air line of the air brake - Google Patents

Description

The device proposed by the applicant provides for a mechanical connection between the open position of the end valves and the closed position of the heads of the connecting hoses of the main air duct, the breaking of which connection, when one or two adjacent cranes overlap, leads to the opening of the heads of the connecting sleeves, the optical signal in the space between the gates and sound signal inside the car.

In FIG. 1 is a side elevational view; FIG. 2-g detail.

Each car crane B (Fig. 1) mounted on the upward bend A of one of the ends of the car air line is supplied, as a handle, with a wheel / handle 2, "the side of the wheel opposite to the handle / connected to a rod 3 (Fig. 2), equipped with a hinge 4, enabling the rod to oscillate in a plane perpendicular to the plane of rotation of the wheel /; for the return of the rod. in the plane of rotation of the wheel / serve as springs 5 on both sides of the hinge 4. The rod 3 has a rectangular cross section and is provided at the end with a protrusion that delays it from sliding along its length

(181)

a hollow clutch b (Fig. 2), fitted on the sides, in a vertical plane, with two signaling half disks 7, painted, like the whole clutch, white. One end of the coupling 6 has a rectangular cavity corresponding to the cross section of the rod, to which the coupling 6 can slide as it moves down the rod 3. The rod 8 is provided at some distance from the free end with a load I and the other end rotatable to the connecting with head G of sleeve B, the end of which, adjoining head G, bears the fixed ring, which has a hook 10 on the side of the sleeve, on which rod 8 rests when it is lowered under load 9. The end valve B remains open Experienced with the lower vertical position of the rod 3 with clutch 6 and the disk 7, as well as with the upper vertical position of the rod 3, with the coupling 6 lowered along it and the disk 7, with the rod 3 fixed by a spring latch 7 /, in which electrical contacts are placed , including a current in circuit 72 to activate a bell J3 placed inside car B with switch 74 under the supervision of a train crew.

To control the crane B, the wheel / is mounted freely on the end 75 of the rotary valve protruding from the body of the crane, but between the wheel and the body of the crane on the same process 75 in a plane parallel to the wheel 7, a protrusion J8 rigidly mounted, moving together with the valve when pressing the right end of its finger 77 connected to the needle 76, the left end of the protrusion J8 is immersed in a bent spring tube 79. A crane and x are equipped with the same type: single head of an adjacent car, but on the reverse side of the sleeve. To overlap one of the cranes B, it is required to move the sleeve 6 away from the bar 8 and inevitably lower this bar downwards, then put the rod 5 in a vertical position in the latch 77, which by turning the wheel 7 will cause the valve plug 7 to close the ledge 78. With this during the course of life, the clutch 6 with the discs 7 will take a vertical position, visible both during the stationary station and during the movement of the train; at the same time, bell 75 will also be inoperative. If the rod 8 with a load 9 falls on hook 70, it will lift the end of it, connected to the head cover P, and turn this head relative to the adjacent head of the opposite arm B, which is accompanied by the opening of the gripper D of both heads. braking part of the train adjacent to the crane, the remaining is not blocked (Fig. 1 half right). Attracted by a call 73 and a signal 6-7, the conductor of the car in which the crane is shut off can push the rod 3 out of the latch 77 and thereby open the valve B, which will cause braking of its car and adjacent to it, in view of the state of opening the heads of sleeve B this carriage.

In the case of overlapping of both adjacent taps B, opening the heads of the sleeves will only open the sleeves B, but the effect of the acoustic and optical signals will remain in force.

In case of rupture of the composition of the rod 8 out of the couplings b, the rod 5 takes

the lower vertical position J, which leaves the cranes B open, while the rods 8 that have fallen on the hook 70 open the heads, causing the whole train to brake. In this case, the output of the rods 8 from the sleeves 6 occurs earlier than the full tension and rupture of the connecting sleeves D, which prevents spoilage of the sleeves and damage to the heads during train breaks.

When coupling and uncoupling the cars, the cockle taps B can be closed or opened by turning the handle 2 with the switch 74 closed.

The subject matter of the invention.

1. A device for detecting closed inter-car valves of the main air brake air duct, characterized in that the rotary stopper of the crane is held in the open position by a two-part rod 5 and connected by movable gear 6, of which part 3 is rigidly connected to the stopper of the crane, and part 8 is pivotally connected to the coupling head of the sleeve.

2. The form of implementation of the device described in claim 1, characterized in that part 3 of the rod is made rotatable in a plane perpendicular to the axis of the plug of the valve, in order to install the signal disk 7 in the corresponding position, with the valve closed, at which position part 3 the bar is held by the latch 77.

3. The form of implementation described in paragraphs. 1 and 2 devices, characterized in that the boom part 8 is provided at the free end with a weight .9 intended to rotate the corresponding half of the coupling head P to disengage the connection when the part 5 falls on the stop 70 when the train breaks.

4. Application when characterized in paragraphs. 1-3 of the adaptation of the electric signaling device 73, 14 and 72, controlling the position of the part of the rod 5, and with it the position of the tap of the crane.
