Description

The utility model relates to railway transport, covered freight cars, including refrigerated cars.

A covered freight car and an end door of a covered freight car are known from the prior art, including upper doors and a lower door adjacent to them from the outside, hinged with the lower edge attached to the floor of the car and equipped with fastening units consisting of rollers located along the free horizontal edge of the door and rigidly fixed on the gripper rollers, mounted with the ability to interact with stops fixed on the upper leaves and door pillars, and handles are hinged on these rollers, while in order to increase reliability by preventing breakage of the lower leaf attachment points during the loading process of the car, each roller is equipped with a longitudinally mounted a spring-loaded rod, each handle is equipped with a cam rigidly attached to it to interact with the corresponding rod and installed eccentrically relative to the axis of the handle mounting hinge, and the lower flap is equipped with guides for the handle fixed to it, each of which contains a restrictive section, which is made along an arc of a circle in the plane , perpendicular to the axis of the specified roller, and a fixing section smoothly coupled with it, located parallel to the axis of the roller (copyright certificate for invention No. SU 1202942 “End door of a covered freight car”, IPC B61D 19/00, B61D 17/20, B60J 5/10, publ. 01/07/1986). This solution was adopted as a prototype.

The disadvantage of the prototype is the unreliability of fixing the handle on the end door from its inside, since the design of the latch does not allow fixing the handle along its entire diameter; the latch in the prototype limits the movement of the handle only in the horizontal direction. Therefore, during the movement of the car, the handle may, moving, for example, in the vertical direction, hit the end door and break. If the handle is not fixed, for example if it breaks, the roller will “fall out” of the holder, and then the end door will be open.

The technical problem is to prevent the handle from breaking and preventing the end door of a boxcar from opening spontaneously.

The technical result of the proposed utility model is the reliable fixation of the handle on the inside of the end door of a covered freight car, which makes it possible to limit the movement of the handle in all directions.

The technical result is achieved by the fact that a covered freight car contains a body with an upper trim and frame, a chassis, automatic coupling devices, braking equipment, an end door, on the inside of which a bolt with a handle is attached, latches, in the through holes of which a bolt is placed, a handle lock , containing an eyelet, in the through hole of which there is an axle with a limiter, a holder is fixed on the upper trim of the body, in the through hole of which a bolt is placed, while the axle is made with a head, the handle lock contains an additional eyelet, made with a through hole in which the axle is located, and on the eyelet located under the handle there is a plate attached.

In this case, chamfers can be made at the ends of the bolt.

In this case, chamfers can be made at the ends of the handle.

In this case, the handle can be installed between the clamps.

In this case, the limiter can be made in the form of a cotter pin.

The inventive covered freight car 1 contains: a body 2 with an upper frame 18 and a frame (position not shown), a chassis 3, automatic coupling devices 4, braking equipment 5, an end door 6, a bolt 7 and a handle 11 connected to the bolt 7. The inventive covered freight car 1 contains: freight car 1 may contain two end doors 6.

On the inside 16 of the end door 6 there are fasteners 9 and 17, in the through holes of which a bolt 7 is placed. The bolt 7 (its upper part) is placed when the end door 6 is closed in the through hole of the holder 8, fixed to the upper trim 18 of the body 2. On the inside On the side 16 of the end door 6 there is a handle lock, which contains an axis with a head 12, a limiter 13 and lugs 10 and 15, fixed to the end door 16 and made with through holes in which the axis with a head 12 is located, fixed in the lugs using a limiter 13 The limiter 13 is installed in the axis with the head 12, in Fig. 4, the limiter 13 is installed in the lower part 19 of the axis with the head 12.

Handle 11, when the end door 6 is closed and the bolt 7 is placed in the holder 8, is placed between the lugs 10 and 15, and is fixed using an axis with a head 12 and a limiter 13.

On the eyelet 15, located under the handle 11 when the end door 6 is closed, a plate 14 is attached, for example, as shown in Fig. 4, for reliable fixation of ear 15.

In order to fix the closed position of the end
door 6, maintenance personnel perform the following actions. They clasp the handle 11 with their hand and, using the handle 11, lift the bolt 7 so that the bolt 7 is placed in the through hole of the holder 8. The bolt 7 and the handle 11 are connected to each other, respectively, by driving the handle 11, they set the bolt 7 in motion. How shown in Fig. 4 and fig. 6 bolt 7 moves in the vertical direction. Next, the handle 11 is placed between the lugs 10 and 15 so that the handle 11 can be fixed using the axis with the head 12 and the stopper 13. The axis with the head 12 is placed in the through holes of the lugs 10 and 15, after which the stopper is inserted into the axis with the head 12 13 so that the axis with the head 12 cannot move, for example in the vertical direction, as shown in FIG. 4. Thus, reliable fixation of the handle 11 is ensured, the movement of which in all directions is limited when the covered freight car 1 is moving.

In order to open the end door 6, all the above steps are carried out in reverse order. The limiter 13 is removed from the axis with the head 12. Then the axis with the head 12 is removed from the through holes of the ears 10 and 15. Next, using the handle 11, the bolt 7 is moved so that it is removed from the through hole
holder 8.

One of the most technologically advanced designs of the refrigerated car 1 is the implementation of chamfers 20 and 22 at the ends of the bolt 7, as shown in FIG. 4. By making chamfers 20 and 22 on the ends of the bolt 7, remove sharp edges that can injure maintenance personnel or damage the holder 8 at the point of contact between the through hole of the holder 8 and the bolt 7. To obtain chamfers 20 and 22, the ends of the bolt 7 are turned on a lathe.

One of the most technologically advanced designs of the refrigerator car 1, which is confirmed experimentally, is the implementation of chamfers 21 and 23 at the ends of the handle 11, as shown in Fig. 4. By making chamfers 21 and 23 at the ends of the handle 11, remove the sharp edge, which can injure operating personnel. To obtain chamfers 21 and 23, the ends of the handle 11 are turned on a lathe. In addition, the presence of a chamfer 21 on the handle 11, namely at the junction of the handle 11 and the bolt 7, makes it possible to achieve ease of welding in this place when connecting the handle 11 and the bolt 7.

One of the most technologically advanced designs of the refrigerated car 1, which is confirmed experimentally, is the installation of the handle 11 between the clamps 9 and 17. In this arrangement of the handle 11, it is convenient for the operating personnel to move it in the vertical direction.

One of the most technologically advanced designs of the refrigerated car 1, which is confirmed experimentally, is the implementation of the limiter 13 in the form of a cotter pin. You can also use a lock washer as a limiter 13.

Based on the above, we can conclude that the set of essential features of the claimed utility model has a cause-and-effect relationship with the achieved technical result, which made it possible to solve the technical problem.

A pilot batch of a utility model was produced, which underwent experimental work and confirmed its advantages.
