Abstract

The invention relates to railway transport and relates to storage of equipment for opening and closing the covers of the discharge doors of a bunker car. The purpose of the invention is to increase reliability in operation. This is achieved by the fact that in the device the elastic element 15, which is connected with the upper arm of the stopper 12 with the one end, with the other end abuts against the stop 16 which is rigidly fixed to the car frame, while connecting the stopper 12 with the cylinder body 1, to eliminate the skew, it contains a hinge 18 attached to it. As a result, an elastic element is applied in the device, which develops sufficient forces for reliable operation of the stopper 12 after the car unloading mechanism is in the transport position. 1 il.

The invention relates to rail transport and concerns devices to open and close:) hatches of bunker cars.

The purpose of the invention is to increase the reliability in operation. : The drawing shows the device, a cross-section.

; The device consists of mounted under the car of the power cylinder 1, the DRIVE shaft 2 connected between the keyhole through the toothed sector | 3, and fixed on the shaft (pisteria 4. Sector 3 is mounted on the BS 5 fixed to the frame of the car by means of the bracket 6. Cylinder 1 | 1 by means of a loop 7, rigidly fixed on the cylinder body, and the axis 8 | is parallel to the brackets 8 of the frame of the car. The loop 7 of the cylinder body 1 has a longitudinal groove located along the longitudinal axis of qi {pindra. I

Stem 10 cylinder 1 pivotally

Axis axis 11 is connected to the cantilever | part of sector 3. On axis 5, a stop 2 in the form of two shoulders is installed, interacting with one arm with a tooth — a ratchet rigidly mounted on the shaft 2 13. To the other shoulder of the stop 12 are articulated by means of an axis 14. Elastic element 15, which is bent with its second end on the tynop 16, which is rigidly attached to the frame of the carriage, as well as ha 17, containing an earring | 18 arnirno attached to it. In this case, the ha ha 18 has the possibility of longitudinal movement in the material of its fastening to the body of the force-bearing cylinder.

The device works as follows.

When compressed air is fed into the upper cavity of cylinder I, the cylinder body, due to the presence of a longitudinal groove in the loop 7, moves upwards and moves the associated with it and the stopper 12 tons gu 17. At that,

with the power of the earring 18, the bias of the rod is eliminated, resulting from the deflection of the upper hinge of the stopper 12. The latter rotates and disengages from the ratchet tooth 3,

thereby unlocking the device for opening and closing manhole covers. When this occurs, the compression of the elastic element.

After the cylinder 1 occupies the uppermost position, its rod, by means of sector 3 and gear 4, rotates the shaft 2, connected by means of, for example, double-arm levers and t, with manhole covers.

After the upper cavity of the cylinder 1 communicates with the atmosphere and compressed air is supplied into the lower cavity of the cylinder 1, its body is lowered by; Well, the longitudinal groove of the hinge 7. In this case, the stopper 12 under the action of the elastic element 15 presses against the ratchet 13. Subsequently, during the movement of the piston of the cylinder 1, the hatch covers are locked, and the stor 12 at the same time under the action of the elastic element engages the ratchet 13,

Form la invention

A device for opening and closing the covers of the unloading hatches of the bunker car, comprising mounted. bathrooms under the car are kinematically connected with the drive hatches; shaft and power cylinder, connected to memsdu by means of an axial sector mounted on an axis, interacting with gear mounted on a shaft, and a shaft locking mechanism consisting of a stopper mounted on an axis sector, rotatable in a vertical plane, made in the form of a two-arm lever interacting with one of shoulders with a tooth rigidly fixed on the ratchet shaft, and connected to the cylinder body by another, and elastic element, characterized in that, in order to increase reliability in operation, the elastic element nt is connected at one end to one arm of the stopper, and the other end of the elastic member is mounted on the stop, which is rigidly fixed to the carriage frame, and said rod is coupled with the stopper scharnirno shackle attached thereto.
