Description

The present invention relates to railway transport, in particular to freight cars with a movable frame (inside the body) for the transport of special products.

A freight wagon is known, comprising running trolleys, brake equipment and a body with a double-leaf end door, in which a movable frame for the product is mounted, resting on rails mounted on the floor of the wagon with its support rollers, and moving with a winch mounted outside the wagon, the frame equipped with hinged supports, which, when rolling the frame out of the car, descending, rely on the rails of the railway track and are fixed with locking mechanisms (Malikov V.G. et al. Ground equipment of rockets. - Moscow: Military Publishing , 1971. - S. 110-112).

The disadvantage of this technical solution is that the product with the help of lodgement trolleys is rolled (rolled out) onto the rails of the mobile frame using a winch mounted on an earth transport trolley, or immersed (unloaded) by a crane.

The closest technical solution to the proposed invention is a freight car, in which a movable frame is installed, consisting, in particular, of two longitudinal beams of the I-section, interconnected by a number of transverse beams, while the longitudinal beams of the frame are fitted with lining guides for moving the product and rollers are placed below the frame beams, which the frame rests on the rails mounted on the floor of the car, and with the help of the drive mechanism located in the car is rolled out to incomplete lengths y, resting one pair of supports on the rails of the railway track.

Loading and unloading of the product is carried out by the drive of a transport-reloading machine (TPM), including a winch, a system of blocks and cables, while the product, moving, is supported by its supporting side bearings on the guides of the mobile frame. (Operation manual. 15 Т 267 РЭ. Approved. 09/27/1993 / Developed by the Central Design Bureau of Transport Engineering (TsKB ТМ). -Tver., 1993. - 137с .: L. 3, 23, 24, 25, 26, 27, 28, 29. Fig. 1.1. - Assembly Sat 00 (l.6) Fig 1.2 (l. 7), Fig.2.1. - Mobile frame Sat 41 (l. 8), Fig 2.2. - (l.9 )

The disadvantage of this technical solution is that a cable drive is used in the TPM, which, due to the uneven tension of the cable branches and slippage in the blocks, moves the product (into the car — from the car) irregularly, jerkily, thereby reducing the accuracy of installation and fastening of the product on a mobile frame , and hence the increase in time for loading and unloading. In addition, in each positional area (the place of loading and unloading), it is necessary to have a TPM with a mechanism for reloading the product.

The proposed invention solves the problem of expanding the technical capabilities of a freight wagon with a movable frame, which will allow serving one wagon several positional areas (places of loading and unloading products) without using additional loading and unloading means during the work, as well as improve the accuracy of installation and securing of the product in a given position due to the use of a chain drive instead of a cable, providing a uniform speed of movement of the product. To achieve the technical result, a mechanism 10 for moving the product is installed on the mobile frame 5 of the car, containing an electric motor 11, a gearbox 12 and two traction chains 13 that are located along the longitudinal beams 14 of the mobile frame 5 and are connected by links 15 to the carriage 16, the transverse beam 20 which is connected using the rod 21 with the product 6 to move it. To eliminate the lateral displacement of the carriage 16 from the lateral force resulting from possible distortions and lateral displacements of the product 6 due to the inaccuracy of the installation of the guides 19 on the frame 5 along which the product 6 moves, rollers 18 are mounted on the sides 17 of the carriage 16, which are supported by rolling their shoulders on the ends of the horizontal shelves of the guides 19 U-shaped section; in addition, the rollers 18 absorb the vertical load arising from the eccentricity of the transmission of traction from the beam 20 of the carriage 16 through the rod 21 to the product 6, resting on the inner or upper pair of rollers 18 on the inner surface of the upper or lower horizontal shelves of the U-shaped guides 19 depending from the direction of movement of the carriage 16.

The proposed freight car is illustrated by the drawings presented in figures 1, 2, 3, 4:

figure 1 shows the car, a General view;

figure 2 - node I of figure 1;

figure 3 is a section aa in figure 2;

figure 4 is a view B of figure 1.

A freight car contains running trolleys 1, brake equipment 2, a body 3 with a double-leaf end door 4, in which a movable frame 5 for a product 6 is installed, which moves along rails 8 mounted on the floor 7 using the drive mechanism 9. The mobile frame 5 has a movement mechanism 10 products containing an electric motor 11, a gearbox 12 and two traction chains 13, which are located along the longitudinal beams 14 of the mobile frame 5 and are connected by links 15 to the carriage 16, consisting of two sidewalls 17, each of which has a pair of rollers 18, interacting ones with guides 19, the U-shaped cross section, mounted on the inner side of the longitudinal beams 14 of movable frame beams 5 and 20, which connects the sidewall 17 of the carriage 16 and connected to each other via rod 21 with the workpiece 6 to move it.

Loading the product into the car and unloading the product from the car are as follows. The wagon is installed on a section of the railway track (or on a special transshipment platform), where they will carry out loading and unloading operations, brake, supply power from the escort car (or from an external source), open the double door 4, roll out the mobile frame 5 using the drive mechanism 9 , make its docking with TPM, connect the product 6 using the rod 21 with the carriage 16, turn on the mechanism 10 for moving the product on the mobile frame 5 and immerse (unload) the product 6. At the end of the overload transfer zhnuyu frame 5 is detached from the vehicle roll in the wagon and fastened. Close the double door 4. The car is released and fed to the place of formation of the train.

The application of the invention will allow one wagon to serve several positional areas (loading and unloading places) without the use of additional loading and unloading means, as well as improve the accuracy of installation and securing of the product in a given position through the use of a chain drive instead of a cable drive that ensures uniform speed of movement of the product.
