Description

Locomotive moving devices made in the form of a hand-held trackless trolley mounted perpendicular to the track and having a lifting lever that communicates at the one end with the locomotive wheel, and the other with the pneumatic cylinder located on it, are known. The disadvantage of such devices is that they are unstable in the process of moving the trolley simultaneously with the locomotive.

The device according to the invention is free from this disadvantage.

The essence of the invention lies in the fact that in order to guarantee reliable operation of the device while automatically following it with the locomotive being moved, the stability of the device is provided by a telescopic strut mounted on one side of the trolley and on the other side of the locomotive.

Automatic switching of the piston (pneumatic cylinder to the working stroke is carried out by compressed air using a three-way valve, which is rotated at one extreme position by the lift lever and at the other edge of the piston.

FIG. 1 shows a side view of the device; in fig. 2 - its top view.

The frame / carriage of the device bears the plate 2 on which the pneumatic cylinder 3, which is open at the top, is mounted. In the slot 4 of the piston 5 of the pneumatic cylinder, there is a roller 6 interacting with one (rear) end of the lifting lever 7, the second (front) end of which is supported support 8 on the trolley frame. The lifting lever 7 is provided with a profile insert 9, by means of which it informs the rotation of the locomotive wheel. The liner surface is grooved. The end of the lift lever supported on the roller is arcuate.

A spool box W with a gold line is welded to the pneumatic cylinder. The Zolotnikov box is connected by air ducts 11 and 12 to the air line and the working cavity of the pneumatic cylinder. On the spool box there is a three-way valve 13, the stopper of which carries the lever 14, which, when the piston approaches to the lowest position, acts on the end of the lift lever, and when the pori approaches the extreme position - the edge of the latter. The slide valve is permuted by compressed air through a three-way valve 13 to which the air pipe is connected //.

A tensioning device 15 is mounted on the frame of the cart; it is made in the form of sarirno connected levers and flexible tie, for example, chains. The free end of the device is provided with a gripper 16, with which it is connected to the locomotive. In order to eliminate the reactive node of the rear part of the cart, the device is equipped with a telescopic stand 17, one end of which is fastened with pin 18 on the frame of the cart, the other rests on the bracket of the ash box of the firebox or the locomotive.

A two-wheeled cart with a crankshaft / I, by turning it with the help of the lever 20, the wheels are lifted. To move the device to the work site on the trolley, there are handles 21.

The movement of a locomotive using the proposed device is as follows.

The device rolls under the back of any wheel of a locomotive and the frame / is laid on the rail. When the valve is opened on the supply air duct, compressed air from the line approaches the valve and through “it through the air duct 12 enters the piston, moving the latter to the upper position. The roller 6 presses the lever 7, and the insert 9, having the profile of the ridge of the brace, will act “the comb,” moves the locomotive to one side or the other.

When the piston 5 approaches the upper position, its edge acts on the lever 14, which, by turning the three-way valve 13, allows air to flow from under the piston to

spool box 10 and move the spool to the upper initial position, after which the cylinder will be in communication with the atmosphere.

Under the action of its own weight and lift lever, the sprout is lowered to the bottom position. When the piston approaches its lower position, the lift lever presses the lever of the three-way valve, through which air enters the slide valve box and moves the slide down, opening air access under the pore-shen. In the following, the cycle repeats.

Subject invention

A locomotive moving device, embodied in the form of a hand-held wheelless trolley mounted perpendicular to the track, with a lift arm interacting with one front end with the rear of any wheel to be moved by the locomotive and the other rear arc-shaped end resting freely on the roller, seated The piston of the pneumatic cylinder, which drives the device, and moves behind the locomotive by means of an attachment device, which is attached to its part, By the fact that, in order to ensure reliable operation of the device and to eliminate the reactive lifting of its rear part, the device is made with a telescopic stand fixed on its frame to rest in the locomotive being moved, and the front end of the lifting lever is made with an insert bearing the profile of the wheel band.
