The invention relates to railway transport, in particular, to devices for closing hatch covers of gondola cars.

The aim of the invention is to increase reliability.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. 1.

The device for closing the manhole covers comprises a housing 1 within which a rod 2 and a spring 3 are located. There is a slot in the housing into which the spike 4 enters, horizontal guides 5 are rigidly fixed in the lower part of the rod, and roller 6 is movably fixed on the bent end of the lower part of the rod 2, inside the guides 5 sliders 7 move with pressure fingers 8, sliders 7 are connected a spring 9, which attracts them to the stop 10. At the ends of the guides 5, the rollers 11 are fitted with the flaps 12. The rollers 11 are connected to the movable roller 13, the closed flap 14 and the round cable 15, the ends of which are fixed on the sliders 7. On the main body 1 hinged up An additional housing 16 with a window through which spike 17 is pulled out, and a limit switch 18 is installed below the window. Inside the case 16 is an additional rod 19 spring loaded 20. A roller 13 is hinged at the lower end of the rod 19. The end switch 18 is connected to a conductor, feeding the motor of the lifting mechanism of the machine carrier (not shown).

The device works as follows.

The device case 1 is hung on the hook of the carrier vehicle, the limit switch 18 is connected to the machine electrooske. Then the device is guided to the car and the operator turns on the mechanism for lifting the load of the carrier vehicle (telpher on the monorail, gantry crane, bridge crane, jib crane, etc.). When the device is lifted, roller 6 seizes the hatch, lifts it and presses it against the car body. Upon further lifting of the crane, the housing 1 moves relative to the rod 2, compressing the spring 3. Together with

He begins to move up the body 16 and the tension of the cable 15 spreads the sliders 7, the fingers 8 of which, pressing on the hatch of the hatch devices, wind them up under the corners of the hatch. When the throws bump into the corners, the rod 19 stops moving and the hook of the carrier machine continues to lift, the housing 16 begins to move relative to the rod 19, compressing the spring 20, until the spike 7 contacts the limit switch 18 and the power supply circuit of the motor of the carrier machine opens.

When reversing the lifting mechanism of the carrier under the influence of springs 3, 9 and 20, the elements of the device occupy the initial position and it moves to the next hatch.

Claims (1)

Invention Formula A device for closing the hatch covers of railway gondola cars, comprising a housing associated with a lifting body, in which a vertically positioned spring-loaded relative to the last rod is installed, on the lower part of which a roller is attached to interact with the hatch cover, and in the middle part of the case a slot is made to the lower part The rods are fixed with horizontal guides with sliders that carry fingers to interact with the ejection, characterized in that, in order to increase reliability, it is equipped with a hinge Attached to the specified additional housing with a spring-loaded vertical additional rod, in the upper part of which a spike is fixed, mounted in a slot, which is made in the additional housing, 5 than the outer switch on the outside of the additional housing is fixed below the said stud to disconnect the drive of the lifting member, and the lower end of the additional rod and at the ends of the said guides are fixed blocks with a cable harnessed in them, the ends of which are fixed to the indicated zunah, the latter being biased one 5 relative to another. 0 five 0
