SU237190A1 - CONTACT BOX FOR AUTOMATIC - Google Patents

Description

Contact boxes for automatic connection of air and electric highways of railway rolling stock are known, which contain a lever system for extending a contact box, mouthpieces of air ducts and electrical contacts located on the automatic coupling.

The described contact box differs from the known ones in that a dog is mounted on the axis of the front part of the box body, entering into the notch of the guide pin of the adjacent box and locking by the striker plate located on the rear movable part of the box. On the back of the box is a hinge-spaced dog, which interacts with its shoulders with the front part and the guide pin of the adjacent box. A spring is installed between the front and rear parts of the box, and the electrical contacts are located on the rear moving part of the contact box.

This difference makes it possible to lock the connecting contact boxes and eliminate the effect of the expansion force of the compressed air in the connected air lines on the coupled automatic couplers, which reduces the wear on the working surfaces of the automatic couplers.

FIG. 3 - two contact boxes in the connected position.

Device for automatic connection of air and electric lines

consists of a contact box / and a lever 2, with which the box is pulled out for connection with an adjacent box.

Contact box / consists of two moving parts relative to another.

The front part 5 of the contact box contains: it has two mouthpieces 4 and 5 of air ducts, interconnected 6, on which is located the guide pin 7 and the hole 8 for the corresponding pin adjacent

the boxes. Ears 9 are located on the back surface of the plate 6 and the Yu dog with the Y-axis is locked. Pin 7 in the upper part has a notch 12, into which the head part 13 of the locking dogs of the adjacent box falls.

The rear part 14 of the contact box contains a rod pivotally connected to the lever 2 located between the mouthpieces 4 and 5, the distance dog / 5 with the axis 16, the locking bar / 7 and the electrical contacts / S.

The dog-dog 15 includes a shoulder 19, abutting against the plate 6, the shoulder 20, interacting with the tongue of the adjacent box, is held in the forward space position

A spring 23 is located between the PLATE 6 and the anvil 22, which ensures the divergence of the front end of the contact box /. The stop 24, and the front part 3 of the box limits the movement of its rear part 14.

When the contact boxes 1 are connected, the guide pins 7 enter the holes 8 in the plates 6 of the adjacent boxes, act on the shoulders 20 of the dogs 15 and turn them on the wasps x 16, moving: 21 and bringing the shoulders 19 out of the stop into the plates 6. After This rear part 14 of each box is brought up to the stop in plate 6. The front end of the locking bar 17 1 stan0 | Wits between the pawl 10 and the stop 25 on the 6 p. . At the same time electrical: contacts 18 are connected to the contacts of the adjacent box. The expansion pressure from the compressed air pressure is only recallable by the pliers 7 and the dogs 10.

When uncoupling the automatic couplers and diluting the contact boxes, first from the rear part 14, WAYS WIPE 6. The striker plate / 7 unlocks the dog 10 and allows the pin 7 of the adjacent box to exit FROM hole 8 or 6 and spin the dog 10. The dog 15 returns to and the first position, setting the shoulders, about 19 iB, the distance between Itoh 6 and 3: adpay part 14 of the box /. In this case, the spring 23, which rests on the support 22, returns to the initial polishing condition.
