Description

The utility model relates to the field of railway transport, in particular to the construction of doors of freight cars and is designed to lock the doors of covered freight cars, can be used to lock the doors of various objects.

A locking device for a sliding door of a covered freight car is known (RU 2415040, B61D 19/00, EV05/14, 03/27/2011), including a claw with a tooth located on the wall of the car with the possibility of rotation around an axis perpendicular to the plane of movement of the car door. The throwing tooth is configured to interact with an arm rigidly mounted on the door. The axis of rotation of the pendant is made in the form of a bolt mounted in a bracket with two flat ends, between which one end of the pendant is placed, in the through hole of which there is a sleeve with flanges placed in the grooves of the bracket. The bolt head is flush mounted in an annular groove made in the bracket, and the cylindrical and threaded parts of the bolt pass through the cylindrical coaxial holes of both flat ends of the bracket, sleeve and wall of the car. The end of the bolt protrudes into the carriage and is equipped with fixing means. The bracket is made of a metal flat tape, the thickness of which is not less than the thickness of the shroud. This roof cargo door sliding device is simple in design and provides reliable door locking with relatively small doorways. The disadvantage of this invention is the need to install a second such locking device for fixing the second door leaf of one doorway of the body of a covered wagon, the need to use a hand tool to fix the locking device.

Known locking device of the door of a freight car, described in PM RU 83791 U1, publ. 06/20/2009, including a tooth gusset mounted on the wagon door trim by means of a rotary axis, a bracket fixedly mounted on a sliding door, the bracket being configured to interact with the gear tooth. Thus, when using a locking device according to the item m. RU 83791 U1 in a body with two doors in one opening, it is also necessary to install a second such locking device for fixing the second door leaf, and there remains a need to use a hand tool to fix the locking device.

In the metro RU 83750 U1 describes a locking device for a door of a freight car, including a tooth lock mounted on the door casing by means of a pivot axis, a bracket fixedly mounted on an adjacent door part of the door, the bracket being adapted to interact with the cog tooth. At the same time: the cast is made in the form of two congruent plates connected by a jumper; on an adjacent element of the door narthex, an additional flat locking cap element is pivotally mounted in the gap between the plates of the flare element; the cap element is provided with a flat safety plate with a protective visor, and each plate of the cap element is equipped with an additional locking tooth located at its free end. When using a locking device, RU 83750 U1 in a body with two doors in one aperture, the installation of a second such locking device for fixing the second door leaf is also required, and there remains a need to use a hand tool to fix the locking device.

The objective of the utility model is to create a door locking mechanism that automatically locks the doors of one doorway between each other.

The technical result is to increase the reliability of fixing the doors of one doorway to each other.

The problem is solved, and the technical result is achieved due to the fact that in the claimed mechanism for locking the doors of a covered wagon, containing a cap with the possibility of rotation around an axis perpendicular to the plane of movement of the wagon door and a tooth configured to interact with an arm rigidly fixed to the door, in contrast from prototypes, the tooth moves along a vertical guide mounted on the door from the inside of the body and provides automatic closing due to the fact that in the open position the tooth is fixed and when the doors are aligned, it moves along the guide under the influence of rotation of the cog caused by the impact of the bracket, and engages with this bracket, while the tooth is additionally fixed from vertical movements by a retainer, the finger of which, when closing the doors, enters the hole of the protective plate welded to the tooth handle .

The technical result of the utility model is achieved by providing automatic locking of the doors when they are combined and increasing the reliability of fixation through the use of a latch.

Thus, labor costs for closing the door are reduced during loading and unloading operations.

The utility model is illustrated by drawings, where:

figure 1 - shows the proposed mechanism for locking doors;

figure 2 - locking mechanism;

figure 3 - tooth;

figure 4 - latch.

The locking mechanism of the doors of the covered wagon includes a locking mechanism 1 (Fig. 1, 2) and a protective casing 2 (Fig. 1) mounted on the door 3 (Fig. 1); fixed to the door 4 bracket 5 (figure 1); mounted on the door 4, the retainer 6 (figure 1) with brackets 7 and 8 (figure 1); a protective plate 9 and a guide bar 10 (figure 1).

The locking mechanism (figure 2) consists of a tooth 11, moving along the guide 12, and the claw 13, rotating around a fixed axis 14, installed in the hole of the guide 12. The guide 12 is bolted by 15 bolts and nuts 16 to two brackets 17. The brackets 17 are welded to door trim 4 and thus lock the locking mechanism on the door trim 4 from the inside of the body.

The tooth 11 (figure 3) is a welded structure and consists of a hook 18, a square sleeve 19, a shank 20, a handle 21, a guide angle 22 and a centering plate 23. An axis 24 is inserted in the coaxial holes of the plate 23 and the corner 22 (figure 2 ) having a thrust head. The axis 24 is located in the slot of the cap 13 (figure 2) and this limits the movement of the cap 13 when it rotates around a fixed axis 14 in two extreme positions - upper and lower. The axis 24 of the thrust head abuts against the centering plate 23, and from the side of the guide angle 22 is fixed by a washer 25 welded to it (Fig. 2).

The cap 13 is fixed from displacement with the fixed axis 14 by the washer 26 welded to the axis 14 and centered on the axis 14 by the washers 27 (Fig. 2).

The handle 21 of the tooth 11 is perpendicular to the plane of the door 4 and through a slot in the skin of the door 4 goes outside the body.

Outside the body, a protective plate 9 is welded to the handle 21 (Fig. 1), made in the form of a corner. When moving the handle 21, the protective plate 9 moves along the guide bar 10 (figure 1).

In the closed position, the handle 21 is fixed from vertical movement by the latch 6 (figure 1). The latch 6 (figure 4) is a spring valve, welded to the bracket 28 with ribs 29. The bracket 28 is welded to the door trim 4. The spring valve consists of a housing formed by welded together pipe 30 and washers 31; finger 32; the washers 33 welded to the finger 32; springs 34 and handles 35 (figure 4). Brackets 7 and 8 (figure 1) mounted on the door 4 are designed to fix the handle 35 of the spring bolt 28 in the extreme positions. In the closed position, the finger 32 under the action of the spring force 34 enters the coaxial hole of the protective plate 9 and holds it from vertical movements, which prevents the handle 21 of the tooth 11 of the locking mechanism 1 from moving.

The mechanism of locking the doors of a covered wagon is as follows. To open the door, the handle 35 of the spring bolt 28 is pulled out of the opening of the protective plate 9 over the edge of the shelf bracket 7, and fixed in a compressed position, leading to the shelf bracket 8.

Then the handle 21 of the tooth 11 is lifted up, the tooth 11 rises to its highest position, while the cap 13 under the action of the axis 24, rotates around the fixed axis 14, rises to its highest position and is fixed in it by moving the center of gravity towards the hook 18.

In this position, the hook 18 of the tooth 11 disengages from the shelf of the bracket 5, freeing the doors to open.

The doors are closed in the following sequence. When combining the doors, the bracket 5 pushes the claw 13, which holds the tooth 11 in its highest position. Under the action of the bracket 5, the hinge 13, rotating around a fixed axis 14, acts on the axis 24 with the upper edge of the slot, thus moving the tooth 11 down. The kinematics of the mechanism is designed so that by the moment the door trim 3 and 4 are in contact, the hook 18 of the tooth 11 moving downward is engaged with the shelf of the bracket 5. The center of gravity of the furrow 13 is shifted toward the shank 20, fixing the furrow 13 in its lowest position.

Then, the handle 35 of the spring bolt 28 is diverted beyond the edge of the shelf of the bracket 8 and rested on the shelf of the bracket 7, while under the action of the spring force 34, the finger 32 through the hole of the protective plate 9 further holds the tooth 11 from vertical movements.
