Description

The invention relates to railway transport, in particular to isothermal freight cars.

A known solution according to US patent 6,178,895 from 01/30/2001, B61D 17/10, which contains a body with a metal flooring and a set of nodes that support this flooring. However, the known design is time-consuming and does not provide the necessary thermal insulation.

The well-known body of an isothermal car (see Jagodin S.K., Sautenkov V.A. Isothermal rolling stock: Textbook for technical schools of railway transport. - M .: Transport, 1986, p. 37-47 and 148-150), including a frame, side and end walls, a roof and a floor of a multilayer structure mounted on a frame, the upper part of which contains wooden blocks, plywood, and covered with rubber. This design reduces its service life, requires a systematic repair of the top coating. In addition, with this design of the floor, which is installed on the frame, the useful height of the body is reduced, which reduces its volume.

For the prototype adopted isothermal vehicle body according to the patent for utility model UA No. 34299 U, B61D 17/00, 02/18/2008. It includes a frame, side and end walls, a roof and a floor of a multilayer structure containing a bottom, a through spinal beam with heat-insulating linings fixed on it, side beams, longitudinal beams, front, pivot and transverse beams with stiffeners welded to them, a top coating and insulating material in the gaps between the frame elements, the bottom and the top coating.

The disadvantages of this design are large heat losses at the junction of the side walls with the floor, the excessive metal consumption of the frame, which reduces the technical and economic performance of the car. In addition, the design is laborious to manufacture due to the presence of numerous profile holes in the upper flooring through which the upper floor is welded to the frame beams, as well as the need to use metal strips in the joints of the upper floor with the longitudinal beams of the frame.

The technical result of the invention is to improve the thermal performance of the body, reducing its metal consumption and the complexity of manufacturing.

This result is achieved by the fact that in the body of an isothermal vehicle, including a frame, side and end walls, a roof and a floor of a multilayer structure, containing a bottom, a through spinal beam with heat-insulating linings fixed on it, side, longitudinal, front, pivot and transverse beams, the top coating and insulating material in the gaps between the frame elements, the bottom and the top coating, the side beams of the frame are made of a corner profile, the horizontal shelf of which is connected to the bottom and the outer sheathing of the side wall, and the vertical shelf is placed in the insulating layer bounded by the inner and outer sheathing of the side wall, the intermediate longitudinal beams are rigidly connected to the upper floor covering, rely on heat-insulating linings mounted on the transverse beams of the frame, and connected to the transverse beams by means of ties welded to the intermediate longitudinal and transverse beams, and heat-insulating gaskets are installed between the bonds.

Heat-insulating linings installed between the intermediate longitudinal beams are located between the bonds fixed on the transverse beams.

Ties welded to the intermediate longitudinal beams are additionally connected to the top floor covering.

Comparison of the proposed technical solution with the prototype made it possible to establish the presence of distinctive features, therefore, this technical solution meets the criterion of "novelty."

The essence of the invention is illustrated by drawings, where:

figure 4 is a section bb in figure 3,

Fig.7 is a section EE in Fig.6.

The body 1 of an isothermal vehicle includes a frame 2, side 3 and end 4 walls, a roof 5 and floor 6. The frame contains a through spinal beam 7, side 8, longitudinal 9, pivot 10, front 11 and transverse 12 beams connected to a single metal structure. The floor is a multilayer structure containing a bottom 13, a top coating 14 in the form of a metal sheet. The bottom is welded to the spinal 7 and longitudinal 9 beams. In the spaces between the frame elements, the bottom and the top cover, thermal insulation is installed 15. The side beams 8 are made of a corner profile. Its horizontal shelf 16 is connected by walls 17 and 18, respectively, to the bottom 13 and the outer sheathing 19 of the side wall 3. The vertical shelf 20 of the corner is rigidly connected with the transverse beams 12 and is placed in the insulating layer bounded by the outer 19 and inner 21 skin of the side wall, which provides the necessary structural strength and reliable thermal insulation in the zone of connection of the floor with the side wall.

Between the spinal 7 and lateral 8 beams, intermediate longitudinal beams 22 of a channel welded by the shelves to the upper floor covering 14 are installed. At the intersection with the transverse 12 beams, the intermediate longitudinal beams are supported by heat-insulating linings 23 mounted on the transverse beams. In the gaps between the transverse beams, the intermediate longitudinal beams 22, as well as the side 8 and longitudinal 9 beams, are in the insulating layer. The pads 23 are placed between the ties 24 welded to the transverse beams 12. These ties are connected to the transverse ties 25 welded to the intermediate longitudinal beams 22. The connection is made through the heat-insulating spacers 26 installed between them, which eliminates heat loss in this zone. In addition, the presence of connections ensures reliable operation of the body when exposed to longitudinal loads on the car.

Between the spinal 7, longitudinal 9 beams and the top floor cover 14, respectively, heat-insulating linings 27 and 28 are installed.

The connection 25, welded to the intermediate longitudinal beams 22, is additionally connected by the uprights 29 with the upper floor covering 14, which increases its rigidity.

The proposed design allows to eliminate heat loss, increase the heat engineering performance of the car, as well as reduce its metal consumption and the complexity of manufacturing.

A prototype is being manufactured and will undergo comprehensive testing.
