Description

Technology area

The utility model relates to the field of railway transport, in particular, equipment for the maintenance and repair of railway cars, such as locomotives, railway cars, metro cars, as well as tram cars, namely, devices that provide safe and convenient access for maintenance personnel to the roof rolling stock for service and repair work.

State of the art

It is known a Device for the maintenance of vehicles (patent document SU 1763266 A1), containing support platforms equipped with stops and pivotally connected to the racks, and ramps, while the support platforms and ramps are made in the form of a trough with a curved base, and the racks are installed obliquely crosswise along in relation to one another and are equipped with stops-locks, while each post is installed with the possibility of interaction with the stop-lock of another post, and the ramps and posts are equipped with supporting heels. The disadvantages of this solution are its stationary location and limited scope (car repair).

Known Mobile stand for the repair of freight cars (patent document SU 765059 A1), containing a portal movable along the rail track, on which a transverse beam movable along the vertical posts of the portal, grips for fixing the car and movable leveling jacks are mounted, with each mentioned grip hinged on vertical post of the portal and is equipped with a drive for moving in the horizontal plane, and the movable transverse beam is equipped with guides in which the said jacks are installed, the working platforms for the service personnel are lifting. The disadvantage of this solution is its lack of mobility (the use of a single portal frame makes the device too cumbersome to move) and the complexity of the design.

Known Complex for straightening and repairing gondola car bodies (patent document No. RU 87974 U1), including a portal frame installed with the ability to move along the path, which contains two drive supports on which the movement mechanisms are mounted, and two idle supports, and is equipped with anti-theft grips for the rail ... Movable platforms are located at the ends of the portal frame and are equipped with a lifting mechanism, on the sides of the portal frame two work platforms are permanently fixed, two side service platforms, on the upper transverse beams of the portal frame there are mechanisms for straightening the end and side walls from the inner side of the gondola car body, on movable end platforms installed mobile hydraulic cylinders for straightening the ends of the gondola car body. Mechanisms for straightening the side panels of the gondola car are installed on the columns of the portal frame with drive supports, in addition, four lifts for lifting the gondola car body and a monorail with a telpher are installed on the portal frame, while the complex additionally includes a straightening platform located on the way, on which two support pedestals are installed with hydraulic grips for fixing the gondola car body, and there is a laser scanning measuring system with four scanning modules. The disadvantage of this technical solution is the complexity of the design.

There is a known railway maintenance platform (patent document CN 109017876), which contains a ladder frame module, a chassis frame; the chassis are connected to form a movable platform, which has its own drive and can be moved along the rails; the ladder module is secured to a mobile platform and the work platform is located at the top of the ladder module; the chassis is connected by a shaft with a quick-release pin, a support is placed on the chassis, and the lower part of the ladder module is fixed to the support using a latching device. The disadvantage of this solution is its limited functionality.

The prototype of the claimed solution is the Stand for the repair of wagons (patent document SU 455 027 A1), containing a portal frame moving along the track, carrying repair platforms for maintenance personnel and equipment, while the platforms are fixed to the portal frame by means of an articulated parallelogram and are equipped with shelves suspended from them also by means of an articulated parallelogram and held in the working position by a locking device. The disadvantage of this solution is its insufficient mobility (the use of a single portal frame makes the device too bulky to move) and safety (repair sites are separated from the frame, attached to it separately, which is more dangerous than a solid structure; in addition, the sites do not provide a sufficient safety system with fences ).

The task of the claimed utility model is to eliminate the identified shortcomings.

Disclosure of the essence of the utility model

The technical result consists in creating a mobile device that provides safe, convenient access for maintenance personnel to the roof of the car for maintenance and repair.

The declared platform for the exit to the roof of the train mobile is an aluminum two-level frame metal structure. At the lower level, for moving the platform, there are four swivel rollers 7 with brake levers. For vertical stability of the platform, extendable screw supports 10 are installed on the lower level. The upper level is a working platform. The ascent to the working platform is carried out using a ladder 8, which has a fence 6. For access to the working platform, a hatch with hinged covers 4 with fixation in the open position is provided 15. To prevent slipping, the floor 12 of the working platform and steps 9 are made of a corrugated steel profile, and - from a corrugated aluminum profile. For safe work on the opposite side of the car, on three sides, railings 2, 3 of the working area are provided.

When performing work on the roof of the car on the site, folding fences 14 are provided and on the side of the car a folding bridge 13 with a pad of porous rubber (shock absorber), which lies on the roof of the car. On the folding rails, a bridge retainer 5 is provided, which protects the bridge from spontaneous opening. With the latch 1, the folding guards are fixed in the open and closed position. To connect two platforms on the folding fences, a locking structure with a tension latch 18 is provided. The folding fences are joined by means of a bar 16, onto which a nut 17 with a hook is screwed, which are designed to tie two folding fences. The connection (locking) of the left and right fences is made when the latch bracket 18 engages with the engagement of the nut 17. After that, it is necessary to pull the fences by pulling the latch handle. On the side of the car, there are rubber shock absorbers 11 on the racks.
