Abstract

The utility model relates to technological complexes for maintenance and repair of rolling stock and is intended to provide convenient access for maintenance personnel to the electric train during its maintenance and repair. An overpass for maintenance and repair of rolling stock includes a beam metal structure on which modular platforms of the lower and upper level of the flyover with end safety devices with side rails and lower lift ladder are provided to provide personnel access to the rolling stock, providing access from floor level to the lower level of the flyover, and the upper lift ladder, providing access from the lower to the upper level of the flyover. The lower ladder is mounted with the possibility of rotation in a vertical plane and fixation in the upper position. The upper level of the flyover contains retractable platforms for servicing equipment located on the roof of the rolling stock. The utility model allows to increase the safety and convenience of maintenance and current repair of rolling stock. 1 ill.

Description

The utility model relates to technological complexes for maintenance and repair of rolling stock (railway, tram, metro) and is intended to provide convenient access for maintenance personnel to rolling stock in the process of its maintenance and repair.

A known repair technological complex for high-speed railway vehicles (see patent RU 91699, B60S 5/00, published on 02.27.2010), including a repair room, a rail device for moving a car inside it, a portal frame movable along a rail track and repair platforms. At least three rail tracks are mounted in the room, between which and on the outer side of the extreme of them are technological compartments. These compartments provide the free movement of the portal frames and maintenance personnel. Both vertical racks of each of the frames are equipped with a drive hoist for moving work platforms. At least one of them has a drive hoist for moving the crane beam with a hoist.

The disadvantage of this technical solution is the low security and lack of convenience of repair work by maintenance personnel.

The objective of the utility model is to eliminate these drawbacks. The technical result is to increase the safety and ease of repair work.

The problem is solved, and the technical result is achieved by the fact that the overpass for maintenance and repair of rolling stock contains a beam metal structure on which modular platforms of the lower and upper level of the flyover with end safety devices and side rails are installed to provide personnel access to the rolling stock, as well as the lower lift ladder providing access from the floor to the lower level of the flyover, and the upper lift ladder, provide ayuschuyu access with the lower level to the upper trestle.

Flyover modules are mounted to metal supporting structures, vertical beams, which in turn are attached to the transverse supporting beams. The entire structure is mounted to the building structures of the building.

The platform does not have supports on the surface of the room, all the load is distributed on building structures and transverse load-bearing beams. To ensure rigidity of the whole structure of the flyover, there are transverse spacer beams and diagonal ties. The absence of supports allows the use of various technical means for the maintenance and repair of rolling stock.

Thus, the creation of a safe and easy-to-operate flyover for repair and maintenance of rolling stock is ensured.

The inventive flyover is illustrated by the drawing shown in figure 1.

An overpass (Fig. 1) consists of a girder metal structure 1 with modular segmented platforms of the upper 2 and lower 3 levels installed on it, a lower lift ladder 4 providing access from the floor to the lower level of the flyover, and an upper lift ladder 5 with access to the upper overpass level.

Modular platforms of the lower level are equipped on both sides with fixed end barriers 6 and 7. Along the platforms of the lower level along the entire length, side barriers 8 are installed, in which there are doors (wickets) 9 for personnel access to the first level of the rolling stock.

The upper level of the flyover contains retractable platforms for servicing equipment located on the roof of the rolling stock. Retractable platforms have side rails 10 that restrict personnel access until the rolling stock is disconnected from the power supply. In the side rails, access doors 11 with electric locks are integrated. Management of personnel access to the rolling stock roof is carried out by an automatic control system according to a specially developed program.

The construction of the flyover along the entire length is equipped with side rails, ensuring the safety of work from the side of the absence of sliding platforms.

The lower stairs, to ensure the passage of vehicles during the work of replacing the units, are equipped with lifting devices, such as a tal-balancer 12. The stairs are raised to the upper position and fixed to prevent spontaneous lowering. The staircase designs have side rails 13.

The length of the flyover depends on the length of the rolling stock and can be changed by dialing the required number of modules.

The use of the proposed flyover will ensure the safety and convenience of maintenance and current repair of rolling stock by maintenance personnel.

Claims (1)

An overpass for maintenance and current repair of rolling stock, containing a beam metal structure mounted on building structural elements of the building, on which modular platforms of the lower and upper level of the flyover, as well as the lower elevating ladder providing access from the floor level are installed to provide personnel access to the rolling stock to the lower level of the flyover, and the upper climbing ladder, providing access from the lower to the upper level of the flyover, while the upper level stakady contains a retractable platform for maintenance of the equipment located on the roof of the rolling stock.
