Description

The invention relates to the field of industrial transport, and in particular to means for supplying railway gondola cars to the tipper.

Known pusher for supplying railway gondola cars to the tipper on.with. USSR No. 328049 (publ. 02.11.1972). This pusher contains a running gear, which includes biaxial bogies with an individual wheel drive, carrying a portal with an arrow mounted on it and its lifting mechanism. The wheels of each biaxial trolley are interconnected by means of balancers connected with the legs of the portal using a fork with a traverse, and a shock absorber is installed between the balancer and the traverse.

When driving off loaded gondola cars and moving along rails with bumps and junctions with high-altitude drops, especially in places where gondola cars are pulled into and off the rails of the car, as well as when braking and pushing an empty gondola car, the pusher experiences significant dynamic loads from aftershocks.

In the well-known pusher for supplying railway gondola cars to the car dumper closest to the offer, shocks and blows are damped by the wheels of the trolley, but at the same time the winch rope branches connected with the boom and pulled by the load stretch freely lying on them oscillate, causing oscillatory movements of the load stretch itself. Under the influence of such an oscillating dynamic load transmitted from the ropes to the upper platform of the portal, the boom lifting mechanism, a machine room with electrical equipment and a driver's cab are found.

The present invention solves the problem of automatically disconnecting the boom lifting mechanism for the time the boom perceives dynamic loads from gondola cars when they are pushing (braking) and directing these loads directly from the boom to the pusher chassis through the portal end beams.

To achieve this technical result, in the pusher for supplying railway gondola cars to the dumper, containing the chassis, including biaxial bogies with an individual wheel drive, carrying a portal with an arrow mounted on it and its lifting mechanism, the arrow contains two longitudinal beams connected by a crossbar, and the boom lifting mechanism includes a winch located on the upper platform of the portal, a system of leveling and deflecting rope blocks, and is also equipped with pylons mounted above the boom booms, the lower ends of which are pivotally mounted on the portal, and the upper ends are connected to the longitudinal booms of the boom using flexible braces, while the upper ends of the pylons are interconnected by a transverse beam that can be rotated and bearing equalizing blocks of the winch rope.

Distinctive features of the proposed pusher for feeding railway gondola cars to the tipper from the above known, closest to it, is the presence in the boom of two longitudinal beams connected by a crossbar, and the lifting mechanism of the boom, which includes a winch located on the upper platform of the portal, a leveling and deflecting blocks of the rope, as well as the supply of the boom lifting mechanism with pylons mounted above the longitudinal boom beams, the lower ends of which are pivotally mounted on the port ala, and the upper ends are connected to the longitudinal beams of the boom using flexible stretch marks, while the upper ends of the pylons are interconnected by a transverse beam mounted for rotation and bearing the leveling blocks of the winch rope.

Due to the presence of these signs during the operation of the pusher for feeding railway gondola cars to the tipper in conditions when the boom is lowered by a winch and a system of leveling and deflecting rope blocks to the gondola car coupler, the fully lowered boom freely rests on this automatic coupler and the portal end beams, and flexible braces are in free condition, that is, sag. Thus, when the boom is fully lowered to the gondola car automatic coupling, the boom is automatically disconnected from its lifting mechanism and, accordingly, the dynamic loads that the boom perceives from the gondola cars when they are pushed (braking) are removed. As a result, this dynamic load is not transmitted along the ropes to the upper platform of the portal, where the machine room with electrical equipment and the driver's cab are located.

The proposed pusher for feeding railway gondola cars to the tipper is illustrated by the drawings shown in figures 1-3.

Figure 1 shows a side view of the pusher for supplying railway gondola cars to the tipper;

figure 2 is the same, a top view;

figure 3 is the same, left view.

The pusher for supplying railway gondola cars to the tipper includes a chassis 1 with biaxial trolleys 2 with an individual wheel drive 3. A portal 4 with a boom 5 and a boom lifting mechanism 6 is installed on the chassis. The boom consists of two longitudinal beams 7 connected by a crossbar 8. The lifting mechanism the boom includes a winch 9 located on the upper platform 10 of the portal, a system of leveling 11 and deflecting 12 blocks of the rope 13. The lifting mechanism of the boom is equipped with pylons 14 mounted above the longitudinal beams of the boom. The lower ends of the pylons by means of the axes 15 are installed on the portal, and the upper ends are connected using flexible braces 16 to the longitudinal beams of the boom. The upper ends of the pylons have coaxial cylindrical bores in which the transverse beam 17 supporting the equalization blocks of the winch rope is pivotally mounted.

The operation of the pusher for feeding railway gondola cars to the tipper is as follows. When individual drives 3 of the running gear 1 are turned on, the pusher with the raised boom 5 moves to the gondola carriage and stops above the second gondola car. The boom is lowered until its bolt 8 is mounted on the automatic coupler 18 of the first gondola, which is fixed by sagging of the flexible stretch marks 16, while the pylons 14 are tilted forward. Winch 9 is turned off. The arrow 5 is freely lying on three supports on an automatic coupler 18 and on two end beams 19 of the portal 4. The load from the flexible extensions 16 is removed, but the branches of the rope 13 of the winch 9 remain stretched under the action of the masses of the pylons 14 tilted forward and the transverse beam 17 with equalization blocks 11 .

When raising and lowering the boom 5, the angle of inclination of the pylons 14 relative to the branches of the rope 13 of the winch 9 changes and the transverse beam 17 rotates in the cylindrical bores of the pylons under the action of the tension of the rope, which eliminates the occurrence of distortions of the branches of the rope in the streams of the leveling blocks 11 of the transverse beam 17.

When the boom is fully lowered to the gondola car’s automatic coupler, fixed by the operator for sagging of flexible stretch marks, the boom is automatically disconnected from its lifting mechanism 6 and, accordingly, it is freed from the dynamic loads that the boom perceives from the gondola cars when they are pushed or braked.
