Description

Devices for moving cars by pushing or pushing them, including in themselves a frame next to the car or in front of it, periodically fixed to the rails, which pushes from the car itself or pulls the car through the gears and tension springs on it generally known (for example, Sov. Pat. No. 27709 from 1932, German. Pat. No. 19111 from 1882 and No. 105001 from 1899 and French. Pat. No. 486482 from 1918).

In the proposed device such as a working gear mechanism, an actuated reversible grip wheel is used, having approximately one half of the circumference teeth for coupling to a rack gear used to push the car, and the other half has a grooved rim for the cable to pull the car .

In FIG. 1 is a side view of the proposed fixture; FIG. 2 - view from above; FIG. 3 front view.

The fixture is mounted on frame 1, which is able to roll by means of rollers 2 on a rail or directly on the ground with the help of two

pairs of wheels 3.3 and 3, of which the latter is made rising. Approximately half of the height in frame 1, two pairs of sliding rods 4.4 and 4.4, connected by spring 5, with hinged forks 13 and 14 at the ends, are fixed in bushes. This spring system, which is attached by forks to the handles for the coupler, serves to periodically rearrange the frame on the rail during operation as the car advances and also to give it some stability at the same time.

At the bottom of the frame above the rail there is a reinforced cross member 6 with two levers 7, bearing on pads 8, adjacent on both sides to the rail head

in such a way that, when the fixture is operated by pushing or pushing, they prevent the frame from moving to the left (according to the drawing), while at the same time allowing it to move back to the right.

At the top of the frame in the supports, there is a shaft 9, on which two levers 10 with folding dogs are loosely attached and stops for these dogs are fastened and an impeller 11 with a grooved rim on one half of the circumference, and on the other half provided with teeth that engage with a rack 12, mounted on frame 1 with the possibility of longitudinal advancement. In the rim of the rim, there is a cable fixed at one end, and attached at the other end to the car to be moved.

The order of operation of the device by pushing the car will be as follows. The frame installed on the rail is brought to the car to be moved, so that the end of the rail 12 ups into the buffer plate of the car. The end plugs 14 of the rods 4 are connected to the handrails for the couplers. Then they start to act with levers 10, pressing them downwards, which is why the rail will press on the buffer of the car and push the latter back from the device (for example, to the right in the drawing). In this case, the pads 8 will, of course, prevent the frame from moving away to the left, and the springs 5 on the rods x 4.4 will compress. When the teeth of the wheel I are close to the end of the rail 12, the pressure of the levers 10 is stopped and, lifting them up, the rail 12 is returned to its former place, after which, thanks to the understanding of the compressed springs 5, the frame is pulled to the car itself until the rail 12 again rests into the buffer . A new push of the car starts, etc.

To move the car by pushing the frame, the frame is brought to it by the other end (for example, left in the drawing), and the levers 10 are thrown to another

(against the position shown in the drawing) side. The rods 4 are connected with forks 13 with handrails for the foremen, and the cable coming from the chute of the wheel I is secured with the free end to the channel (or even to the frame) of the wagon. From acting on the levers 10 thrown to the right, wheel 11 will rotate, and the cable will push the car to frame 1, which is fixed on the rail, and springs 5 will also be compressed, and on raising the levers, unclip, move the frame away from the rail. The levers 10 are lowered again, the tightening is repeated, and so on.

The subject matter of the invention.

Device D1 for carriage movement consisting of a bed movable on wheels with a gear mechanism fixed on it, a gear mechanism manually inducing a gear rack in a pushing movement, with a spring and gripping rails, with a bed stop at the time of car movement, legs that differ that, in order to use the device also for pushing the car, an incomplete gear was used as the driving wheel 11, the circumference part of which, devoid of teeth, is provided with a groove adapted for fastening in one of its ends of the cable, pushing to the frame of the car.
