Description

Devices for stopping carriages moving on rails at a certain place on a path, driven by carriages themselves, are generally known. In the proposed such device, the vehicle is stopped by having two rail-mounted and interconnected basmas moving from the rail to the side, at the approach of the vehicle, under the action of its special emphasis on the lever system of the device associated with the shoes, and held in this position by pressing on them the side face of the front wheel of the wagon until it passes the second shoe. Then this pressing is stopped, and both shoes, with the action of their springs, slide back onto the rail between the front and rear wheels of the cart and, thus, stop it at the place where the device is located.

This device is predominantly designated for use on in-plant rail tracks.

In FIG. 1 shows a top view of the device; FIG. 2 is a side view of the track, and FIG. 3-view it along the way.

The device is mounted on the plate 6, laid under the rails in the place of the required stop of the wagon. On the head of the rail 7 two directional spikes are placed in opposite sides of the shoe 3, 3, which are connected between each other by a plank 2. The distance between the spikes of the shoes must be less than rigs (304)

nor between the front and rear wheels of a wagon. The shoes have tails 4, 4 arranged perpendicularly to the rail, passed through guide bearings 5, 5 and fitted with springs 7 /. At the top of the uprights 6 fastened on the slab 6, 7, a rotary roller 76 is located parallel to the rails, having a curved lever 8 at one end, and in the middle between the posts a lateral process in the form of a paw 9 with a forked end. Below the roller 75 in racks 7, 7 lies another roller 77, the bent ends of which 18 are articulated with the shanks 4, 4 of the shoes; in the plane of the above-mentioned paw 9, the roller 77 is provided with a side lever W.

Before the passage of the carriage shoes 5, pushed to the side of the rail springs 11, lie on the rail head (Fig. 1-3). When approaching the wagon 12 (on the right in FIG. 1 - 2), its stop 75, before the front wheel of the wagon reaches the first shoe, acts on the lever 8 of the roller 16, turning its paw I which presses the lever below it 10 roller 77, why the curved ends 18 of the latter, acting on the shanks 4, 4 shoes and compress the spring 77, shifted, shoes from the rail head to the side. Thus, the passage on the rail for the front wheel of the wagon will be released, and as the wheel passes by the shoes and rail, it will be its side face

hold them in a shifted position. As the second wheel passes the second shoe, this lateral pressing on the plate Ina shoes stops, and the latter, under the action of their springs 77, begin again on the rail head M (each time the front and rear wheels and thus stop the wagon).

The release of the shoes from under the wheels of the wagon, in order to be able to continue, is done by turning the handle 16 mounted on the roller. “And acting in the same way as the lever 8.

The subject matter of the invention.

Claims (3)

1. Travel braking device activated by the carriage itself, 1different to the fact that it is done 8 view of two connected shoes, under the action of springs, in such a way that, by the action of the cart frame, the shoes are shifted to the side, keeping all the time in this position until the front wheel passes the track device, after which the spring action becomes in the space between the wheels . 2. The form of the device according to claim 1, characterized in that it uses a lever 8, which is affected by the frame of the cart for deflecting the shoes, having a paw 9, on which the lever 10 is connected, connected by means of the shanks 4 with the shoes. 3. The form for making the device according to claim 2, characterized in that the lever 8 is provided with a handle 73, which serves to free the shoes from under the wheels of the cart for its further movement. figs 6 17
