Description

Description of the invention

The useful model refers to railway transport and can be used in passenger 2 carriage construction during the construction of carriage ceilings.

The ceiling of a passenger car is known from the author's certificate of the USSR Mo1253861, MKV 4 В6И017/08 "Carrying panel of the body of a passenger car", 1986. The specified analog contains a flat skin, reinforced with longitudinal and transverse elements, made as a single skin, has a cross section in the form of " and connected to the cladding by the top, and the transverse elements are made of a T-shaped section and the free edge of the wall is rigidly attached to the shelves of the longitudinal elements. However, this implementation is difficult, creates inconvenience during assembly and has insufficient operational reliability.

The ceiling of a passenger car is known from the patent of the Russian Federation "Connection of ceiling panels in a car", Mo2232091, IPC 7 V61017/18, 2004. This technical solution is taken as the closest analogue (prototype).

A copy of the prototype is attached. 19 The ceiling of the passenger car, according to the prototype, contains a support frame, gripping elements, a panel, fastening parts, while the panel is made in the form of a semi-cylindrical spacer element enclosed in a tape-directed element, and the gripping element has a mounting gap.

Features of the prototype coinciding with the essential features of the claimed utility model are: support frame, gripping elements, panel and fastening parts.

The disadvantage of the ceiling of the passenger car, according to the prototype, is the inconvenience of its assembly and low operational reliability. This is explained by the fact that in the prototype the panel is made solid, and the gripping elements require, during their assembly, the introduction of panel loops into raw brackets and their loose fixation at the same time in several places to welded metal strips. Such a provision does not exclude the negative impact of vibration during the movement of railway rolling stock on the connected nodes and affects the operational reliability of the entire ceiling. The prototype also does not provide 22 overlapping gaps at the joints of the support frame and the panel, as well as safety elements as safety devices. -at

The basis of the useful model is the task of improving the ceiling of the passenger car by improving its design due to the fact that the panel is made of components in the form of side and central parts fixed on a support frame with the possibility of rotation, and the gripping elements are connected by spring loops, and the gaps between the parts panels covered with visors. This allows to increase the convenience of assembly and operational reliability. Ge")

The task is solved by the fact that the ceiling of the passenger car, which contains a supporting frame, gripping elements, a panel and fastening parts, according to a useful model, the panel is made of components in the form of side and central parts, fixed on a supporting frame with the possibility of rotation, and gripping elements with connected by spring loops, and the gaps between the parts of the panels are covered with visors. 3. The cause-and-effect relationship between the set of essential features of the useful model and the achieved result is provided by the follower. Making the panel composite, in the form of side and central parts and fixing them on a support frame with the possibility of rotation, allows to increase the convenience of assembling the ceiling as a whole. "

The connection of the gripping elements with spring loops, as well as the overlapping of the gaps between the parts of the panels with visors, allows to increase operational reliability. The connection of the central part of the panel with the support frame 70 by a safety belt creates safety conditions during operation. c The ceiling of the passenger car is explained by the drawings, where Fig. 1 shows a general view from the side; in Fig.2

From" - view A in Fig. 1 with a plan showing the positions of the component parts of the panel and their fastenings on the support frame; in Fig. 3 - section B-B in Fig. 2 at the place of attachment of the gripping elements and the position of the central part of the panel on the support frame; in Fig. 4 - section B-B in Fig. 2 at the place of attachment of the safety belt of the central part of the panel with the support frame; in Fig. 5 - section GG in Fig. 2 with a view of the joints of the panels and their overlapping with visors. and The ceiling of the passenger car consists of a supporting frame 1 with stiffeners 2. On the latter with the help of 4! hinged hinges From the side parts of the panel 4 and the central part of the panel 5 are fixed. The parts of the panels have gripping elements 6 connected by spring loops 7 with gripping elements 8 located on the supporting frame. All gripping elements are fastened with fasteners 9 in the form of bolts and washers. Gaps between parts

Ge) 20 panels are covered with visors 10, fixed with fasteners 11. The central part of the panel is connected to the support frame by a safety belt 12 with the help of fasteners 13, and this part of the panel has an opening in the form of a hatch 14 for placing ceiling equipment.

The work on the assembly and installation of the ceiling is carried out as follows.

The elements of the support frame 1 and stiffeners 2 are prepared in advance and welded together. Then

So" make the side parts of the panel 4 and the central part of the panel 5, attach hinged hinges 3 to them, and connect the latter to the supporting frame. Gripper elements 8 are attached to the latter, and gripper elements b are attached to parts of the panels, spring loops 7 are installed on them and fixed with fasteners 9. After that, the gaps between the parts of the panels are covered with visors 10 and fixed with fasteners 11. Safety belts are installed on the central part of the panel 12 and strengthen them with fasteners 13, 60 while maintaining access to the hatch 14. If it is necessary to install the equipment in the area of the roof of the car, both types of panels can be turned away by turning them on hinged hinges.

The ceiling of the passenger car allows to increase the convenience of assembly and operational reliability. b5 i / "
