Description

The proposed utility model relates to the design of the drain devices for tank cars.

Known drain device (Wagons: textbook for universities of railway transport / L.A. Shadur, et al., M .: Transport, 1980. - 439 p.), Which includes a body surrounded by a heating jacket, the main shutter, consisting of a rod, the upper end of which is equipped with a folding knob, and the lower end is screwed into the rack, at the bottom, the rod is connected to a valve with upper and lower feathers, a rubber ring reinforced with a pressure ring and pins, an additional shutter, consisting of a cover with a rubber sealing ring, which is attached to the cover with a ring and bolts, while the cover is fixed to the body tip with a screw, and the screw support is made in the form of a hinged bracket suspended on rollers that are attached to the body tip, while the cover is equipped with a lock nut with a handle.

The disadvantage of the known technical solution is the inconvenience in operation, which is associated with the design of the swing gate. The knob has a T-shape, while the rod is rigidly connected to the handles, and the length of the handles is limited by the condition that in the transport position the knob must fit inside the filler neck of the manhole so that the filler neck closes. When using this wrench, the length of the handles is not enough to create the required torque, especially in the cold season, if the valve freezes to the seat, as a result of which the operator must use additional means to increase the lever arm, for example, using a pipe extension on the handle, which violates the technique security. Also, in the transport position, the knob is in a horizontal or inclined position in the neck of the manhole, while the knob at the bottom becomes dirty with the transported product, after which additional time is spent on cleaning it with further use.

Known drainage device railway tank, adopted as the closest analogue (patent RU 2182091), including a rod, which in the area of the filler neck is kinematically connected to the control handles due to the presence of a rotary sleeve connected to the handles. The inner surface of the neck has supporting elements for laying the control handles during the transportation of the tank. The presence of a rotary sleeve on the rod ensures the rotation of the latter in a vertically oriented position relative to the rod at the operating position of the locking device and rotation of the handles to their horizontally oriented position when placing the latter on the supporting elements of the filler neck.

The technical problem of the known technical solutions is the inconvenience of using the drain device.

The technical result is to improve the ease of use of the drain device of the tank car.

The claimed technical result is achieved by changing the design of the hinged gate of the main shutter of the drain device by introducing a hinged connection between the rod and the handles, which will allow the handles to be folded for ease of use and make their length in working condition in the range from 0.9D to 1.2D mm, where D - the inner diameter of the manhole, while in the inoperative position the swing gate is not contaminated with cargo when the tank is filled to the upper filling level.

When the length of the handles in the working position is less than 0.9D mm, it is not enough to create the required torque when turning the folding knob to open and close the drain device. When the length of the handles in the working position is more than 1.2D mm, it is impossible to transfer the folding wrench to the inoperative position.

Bringing the swing gate to the working and non-working position is carried out due to the articulated connection between the rod and the handles, while the swing gate rod is asymmetrically mounted in the mouth of the manhole and pivotally connected to the drain bar to be located inside the mouth of the manhole in the inoperative position. The articulated connection consists of a rod with a coupling fixed on it, axles are inserted into the ends of the coupling, on which the handles are fixed, the handles are fixed in working condition due to flat springs. In the working position, the folding knob is installed vertically, the handles are fixed against rotation in the articulated connection. When inoperative, the handles are folded, the folding knob is horizontally placed in the neck of the manhole.

The proposed utility model is illustrated by graphic material:

in fig. 1 shows a general view of the drain device;

in fig. 2 - folding knob in working position;

in fig. 3 - folding knob in non-working position.

The draining device shown in FIG. 1, includes a body 1 with a hatch-manhole neck, the main shutter, consisting of a rod 2, the upper end of which is equipped with a folding knob 3, and the lower end is screwed into the post 4, at the bottom the rod is connected to the valve 5, an additional shutter consisting of a cover with rubber sealing ring 6, while the rod 7 of the swing gate is asymmetrically mounted in the mouth of the manhole and pivotally connected to the rod 2 of the drain device to be located inside the throat of the manhole in the inoperative position.

FIG. 2, the folding knob is shown in the working position and includes a rod 7, with a coupling 8 fixed on it, axles 9 are inserted into the ends of the coupling 8, on which the handles 10 are fixed. Flat springs 11 are connected to the handles 10, fixed on the rod 7 with bolts 12. In the working position, the folding knob 3 is installed vertically, and the handles 10 are fixed by means of flat springs 11.

FIG. 3 shows a folding knob 3 in an inoperative position, while the handles 10 are folded and fixed by means of flat springs 11, the knob is horizontally placed in the throat of the manhole.
