Abstract

The invention relates to railway transport, in particular, to devices for closing hatch covers of gondola cars on the go. The purpose of the invention is to increase productivity by reducing the idler's idling speed. The device has two installations located on both sides of the railway track. Each unit contains a stand 1, a turntable 2 pivotally connected to the stand, a hydraulic cylinder 3 connected to a turntable on which the drive 4 is placed. The ram 5 includes a rotor with levers equipped with roller clamps 9, the distance between the axes of which is 0, 8 - 1.2 the distance between the axles of the hatch covers of the gondola cars. With the passage of the empty composition and rotation of the elevator 5, each roller grip 9 rolls over the corresponding hatch cover and closes it. During one revolution of the hopper lifter, the number of hatches is closed, which is equal to the number of levers with roller grippers 9. 2 Cpt f-crystals, 5 Il.

This invention relates to rail transport, in particular to devices for closing hatch covers of gondola cars on the go.

The purpose of the invention is to increase productivity by reducing the idle speed of the lyukopodemnik.

FIG. 1 shows a device for closing hatch wagon covers, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view of B in FIG. 3; in fig. 5 is a graph of the trajectory of dai e grabs relative to the gondola.

The device for closing the hatch covers of gondola cars contains two installations located on both sides of the railway track. Each unit contains a stand 1, a turntable 2 pivotally connected to the stand, a hydraulic cylinder 3 which is mounted on the stand and a rod connected to the turntable on which the drive 4 is placed. The lifter 5 includes a rotor 6 connected to the drive levers 7 installed radially with respect to the center of the rotor and attached to it by means of elastic elements, for example flat springs 8, with the possibility of swinging in planes passing through the axis of rotation of the lyuko-lifter, which is perpendicular to the lateral surface m of gondola cars. The levers 7 are equipped with roller grippers 9, which are kinematically connected with the levers through elastic elements 10 and comprise bodies 11 with guide shanks 12, rollers 13 with axes 14. The distance between the axes of roller grippers 9, which interact with the manhole covers, is selected equal to 0.8-1.2 the distance between the axles of the hatch covers of the gondola cars.

The drives of the left and right lyukopodyem are not connected by a cardan telescopic gear 15.

The device works as follows.

In the initial position, the hoist lifter 5 occupies the lowest position, ensuring the passage of rolling stock to unloading. When the empty train passes back, for example, by a wheel flange, a contact of the automatic lifter's control device (not proven) is turned on, the lyapograiser 5 is moved to the upper operating position by the action of hydraulic cylinders 3 on the turntable 2. At the same time, the drive 4 is turned on with the required speed and phase of rotation. Lever 7 meets the roller grab 9

the hatch cover and starts its rise, deflecting simultaneously in the plane passing through the axis of rotation of the ram, due to the elastic connection with the rotor. Elastic

element 8 makes it possible to compensate for the difference in size from the axis of rotation of the sky-lifter to the surface of the manhole covers in the closed position, and also provides for limiting the force on the cover not exceeding allowable. The number of manhole covers that are closed for one revolution of the lyopodiechnik is equal to the number of levers 7. mounted on the rotor 6. The number of levers in the lyopodjemnik 5 of the device intended for operation

5 on an elevated path, you should choose from a number of 5-7. For example, with equal performance, the performance of the five-link hopper is 20% higher, and the requirements for operating accuracy of the control system are lower than those of the seven-link hoist. In the absence of an elevated path, it is preferable to design a hopper with three levers. In the above options for the construction of the elevator, the trajectories of the relative movement of the gripper 9 extend as far as possible from the protruding parts and assemblies of the gondola car, ensuring trouble-free operation of the device.

Claims (3)

1. A device for closing the hatch covers of gondola cars, which contains a frame installed parallel to the railway track, on which a hatch lift is mounted with a drive in a vertical plane, including a roller lever for interacting with the hatch cover, from the h e with the fact that, in order to increase 0 performance by reducing the idler's no-load, the latter is formed by a rotor whose axis is perpendicular to the side surface of the gondola, on which the specified lever and additional levers with roller grips are mounted radially to the center of the rotor. 2. The device according to claim 1, that is, so that the levers are connected to the rotor 0 elastic elements with the possibility of swinging in a plane passing through the axis of rotation of the rotor. 3. A device according to claim 1, characterized in that the arc distance between the wheels is 0.8-1.2 the distance between the axes of adjacent hatches, the number of levers being equal to the number of hatches that are closed during the rotation of the rotor.
