Description

The utility model relates to the field of railway technology, namely to isothermal cars.

From the patent for utility model No. 76057, a mechanism for opening and closing the door of a covered carriage is known, consisting of a locking device, including a locking lever with a threaded spindle and horizontal rods hinged to them on the sides of the door with adjusting screw ties and vertical pressure shafts, to which they are rigidly attached cams interacting with the brackets of the doorway and the diverter device, which includes two rotating shafts with folding levers and upper and lower cranks hinged to the shafts, which, in turn, are connected to the corresponding roller supports, kinematically connected to the guides of the doorway, characterized in that that at least one crank is equipped with a vertical lock with a hole that coincides with the hole in the guide when the door is closed (RU, No. 76057, IPC E05B 65/14, B61D 19/00, publ. 09/10/2008).

A known sliding door of an isothermal vehicle contains an opening and closing mechanism located in a recess of the car door, made on its outer surface, characterized in that a folding casing with eyes is hinged above the recess, equipped with holes for installing locking devices in the open and closed positions of the casing. (RU, No. 181434, IPC B61D 19/00, published 07/13/2018).

An isothermal car is known, containing a chassis and a body, the body has end and side walls, as well as a roof and floor, which limit the internal space of the body; an opening is provided in the side wall (2) of the body for access to the internal space of the body and is designed to close said opening the door (1) is of a rotary-sliding type, and the side wall (2) on the outer side is equipped with a guide system for the door (1), which includes upper and lower longitudinal guides (3, 4), in which the door (1) is installed with the possibility of longitudinal displacement through its upper and lower rollers (5, 6), characterized in that the upper guide (3) is made in the form of a support guide with a tubular profile (9), on the inner surfaces (12, 13) of which the upper rollers rest on top ( 5) door (1), so that the door (1) is suspended on the upper guide (3), and in the downward side of the tubular profile (9) there is a groove (10), through which the door rollers (5) are connected to the door itself ( 1), the lower guide (4) is a limiter for the lateral displacement of the door (1), which perceives only the lateral load from the lower rollers (6) of the door (1) (RU, No. 202157, IPC B61D 19/00, publ. 02/04/2021).

From the patent for utility model No. 182555, a mechanism for opening and closing the sliding door of an isothermal freight car is known, containing a diverter device, including two rotating shafts with folding levers and upper and lower diverter cranks hinged to the shafts with roller supports, kinematically connected to the doorway guides, characterized in that the roller supports on the lower outlet cranks are made with an additional horizontal axis of rotation perpendicular to the direction of movement of the roller (RU, No. 182555, IPC B61D 19/00, E05D 15/06, publ. 08/22/2018).

A common disadvantage of the known solutions is the lack of mention of a central locking device with a clamping device for the mechanism for opening and closing the car door. These devices are usually not protected from third-party influence (penetration), which does not exclude the possibility of the door depressurizing.

The technical solution for utility model patent No. 202157 was adopted as a prototype.

The technical problem solved by the proposed utility model is the insufficient reliability of the mechanism for opening and closing the car door.

The technical result consists in increasing the operational reliability of the isothermal car.

The glass can be made in the form of a pipe with a plug.

The glass can be made of metal.

The glass may have a thread.

The central axis may have a thread for movement in the glass.

The central axis is secured to the handle and body of the central locking device.

The door locking and opening mechanism is recessed into the door frame to a depth of h=49.5 mm.

The shaft with cams can be secured to the door frame with brackets.

The bracket may have a lifting loop and two ribs.

The inventive isothermal car contains a body 1 with a frame 2, a chassis 3, automatic coupling devices 4, braking equipment 5, a door 6. On the door 6 of the isothermal car there is an opening and closing mechanism (not designated by a position), which contains a central locking device (conventionally by the position not designated), which includes a housing 7, with a threaded central axis 8 with an oiler 9. A handle 10 is rigidly fixed to the axis 8. The 8 axis moves in a glass 11 in the form of a threaded pipe, with a plug 12 at one end.

On the outside, on the sides, the housing 7 has ribs (not conventionally designated in the figures) with holes for hinged fastening of rods 13, which are connected to the shaft 14, on which cams are attached, fixing the door 6 in the closed position. A pressure rib 15 is fixed on top of the body 7, interacting with the axis 16 of the clamping device 17. The clamping device 17 fixes the folding levers 18 in the “closed” position. For better closing, the folding levers 18 are oriented by the limiter 19 and the guide 20 of the folding lever 18. The folding levers 18 are fixed to diverting devices 21, at the ends of which there are upper 22 and lower 23 cranks, moving in operating condition on roller bearings 24 along guides 25 and 26. The axis 8 is located in the glass 11, which is rigidly connected to the ribs 27. The glass 11 with the ribs 27 is rigidly fixed inside the frame of the sliding door 6. The axis 8 is rigidly fixed to the handle 10, the rotation of which activates the central part of the door locking and opening mechanism. The axis 8 and the internal cavity of the cup 11 have a thread to interact with each other.

The mechanism for locking and opening the door is recessed into the door frame 6 to a depth of h = 49.5 mm, determined by the calculation method; in any case, the depth must correspond to the unhindered tilting of the levers 18.

The shafts 29 of the cranks 22 and 23 are additionally attached to the door frame 6 with brackets 30 in various parts of the door 6, the main thing is that the load is evenly distributed.

The shaft with cams 14 is secured to the frame of the door 6 by brackets 31, and at least one bracket 31 of each folding device has a rigging loop (not conventionally designated) for transporting the door 6 when assembling the insulated car. The brackets have two ribs (not conventionally designated by position), which are used to attach them to the diverter device.

The device works as follows.

During operation of the isothermal car, the handle 10 of the mechanism for opening and closing the door is in the “closed” position, while the pressure rib 15 is tightly pressed against the axis 16, fixing the folding levers 18.

To open the sliding door 6 by the mechanism, you should move the handle 10 to the “open” position by turning it clockwise until the shafts with cams 14 come out of the engagement of the brackets (position not shown) on the car body. In this case, the housing 7 with the rigidly fixed pressure rib 15 moves, releasing the axis 16 of the clamping device 17.

The folding levers 18 are pulled towards themselves, it becomes possible to move the door towards itself and to the side until it stops, after fixing the roller support 24 with a hook 28, the folding levers 18 are lowered and fixed in the brackets - which corresponds to the “open” position. The process of closing the door is exactly the opposite of the “open” position. At this time, handle 10 is turned counterclockwise.

When opening and closing the door 6, the axis 8 in the glass 11 moves along the thread. Due to the fact that, to securely fasten the mechanism, the axis 8 is closed with a plug 12 in a metal cup 11, which is rigidly connected to the ribs 27 in the door frame, which prevents sprayed thermal insulation from getting on the axis 8, the tightness allows heat or cold not to escape, i.e. . This way the temperature is regulated without sudden changes. The clamping device 17, fixing the folding levers 18, prevents the opening of the door 6, thereby ensuring the reliability of the mechanism for opening and closing the door. All this has a beneficial effect on increasing the reliability of the car as a whole, without breaking down before the warranty period. Consequently, the claimed utility model makes it possible to increase operational reliability.
