SU63699A1 - Attachments for attaching and shooting coupled girders of locomotives - Google Patents

Description

Lifting devices are known which consist of a tubular stand with two pivotally connected levers. The second ends of these levers are connected with earrings with a ring moved by a screw mechanism.

The present invention aims to utilize these known devices for attaching and capturing the coupling heads of locomotives. This is achieved by the fact that the levers are equipped with two legs with movable inserts: With these legs, the device covers the drawbar of the locomotive when hanging and shooting.

The drawing depicts the proposed adaptation in FIG. 1 in a front view, in FIG. 2 in a side view, in FIG. 3 shows a section along the line A-A of FIG. 1, in FIG. 4 shows a screw mechanism for moving the levers; FIG. 5 is a section through and FIG. 6 shows a section along CC of FIG. 4, in FIG. 7 - the node K of FIG. 1 and in FIG. 8 is a N — N section of FIG. 7

The device consists mainly of a tubular rack 1, two levers 3 and a lifting mechanism with a flywheel. In the slot of the lower end of the post 1, the base 2 is welded to which on both sides are fastened with a bolt and nut 25 and 26 of the eyelet 4 of the levers 3.

A paw 5 is welded to the second end of each lever (Fig. 7), on which the liner 6 is resting. With the help of a cotter pin 7 and a slot in the paw 5, the paw is attached to the liner.

Earrings 8 pivotally fastened to the paws 5, their upper ends are also pivotally hinged to the ring 9 with a loop. The latter is suspended to the screw 10 by means of eyelet 12 and a bolt with a nut 23 and 24. Spacer 11 prevents the screw 10 from deviating to the tension side earl 8.

The cut part of the screw is mated to the conical bristle 13 by means of straight cutting.

The conical gear 13 is fixed in a stopper, made in the form of two halves of the support ring 15, the latter are fastened to the rack 1 by means of bolts 16.

The bevel gear 14, which meshes with the bevel gear 13, sits on the shaft 17, which can rotate in the bearing 18.; M. The flywheel consisting of the hub 19, the spokes 20 and the rim 21 s

handles 22, mounted on the shaft 17 with a nut.

When attaching the drawbar under the drawbar, laid on the floor near the slopes of the steam locomotive, both legs 5 with inserts 6 are brought in, and the heads of the two adjacent breathers are located between the inserts. After the liner 6 seizes the lower part of the drawbar, it begins to lift.

The handwheel must be rotated clockwise to raise it. Together with the flywheel, the shaft 17 and the bevel gear 14 rotate, which meshes with the bevel gear 13. 6

After this, the process of mounting the borehole is performed.

This requires the required alignment of the axle of the hub of the drawbar with the axis of the pin of the coupling axle.

Deviation of the device

having a fulcrum on the floor at the base 2, “from oneself, the approach of the breather to the fingers is reached. The further deviation of the device from itself, which is necessary for putting the breathing device on the fingers, is combined with simultaneous fitting by turning the flywheel in one direction or another.

Simultaneous execution of the two operations (deviation

and eyeliner) makes it possible: 1), quickly install the axle of the bushings along the same axis with the fingers, and 2) send a quick hanging of the latter.

The same operations are performed for lifting the breather, but in reverse order. First, the vehicle inserts 6 are inserted under the drawbar rods hanging on the fingers of the coupling axles. Then, with the simultaneous insertion of the device, the breather is removed from the fingers so that the latter remain laid on the inserts of the device. By turning the handwheel counterclockwise, the lowering of the breather is achieved until their heads rest on the floor. By further lowering the ends of the levers 3, the inserts 6 can be pulled out from under the rods.

Subject invention

A device for hanging and filming coupling drawbars, consisting of a tubular stand with two pivotally connected levers, the second ends of which are connected to the ring by a screw mechanism, which is located on the levers, with two arms covering the tongue with movable inserts.
