Abstract

Flatcar for sheet steel in rolls contains frame mounted on two running carts, equipped with supporting beds for positioning on them the cylinders along the railroad car. Two extreme beds, which are located along the side beams of frame, are fixed. Two middle beds are adjustable for size change between them and between the extreme beds, ensuring the arrangement of rolls into one, two or three rows along the frame.

Description

Description of the invention

The utility model belongs to railway transport, namely to specialized freight wagons for 2 transportation of rolled steel sheets in rolls with the arrangement of rolls along the wagon. Schemes for the location of rolls and the orientation of the roll axes relative to the longitudinal axis of the wagon are mostly determined by the customers of the wagons, depending on the technologies and equipment adopted at their enterprises for loading and unloading operations.

There are well-known specialized wagons for the transportation of rolled sheet rolls, for example, models 12-4011 (1), 70 (2), with longitudinal placement of rolls. In such wagons, the bearing supports have a tilting design and allow placing rolls along the body in no more than two rows.

The useful model offered provides transportation of rolls with a diameter from 800 to 1800 mm with their placement on the frame platform in one, two or three rows, which increases the technical and economic indicators of the car due to the possibility of transporting a larger standard size row of rolls and a greater useful load on linear meter of the length of the car.

The useful model of the claimed platform car belongs to the class of short-base structures of freight cars, is a frame 1, Fig. 1, 2, mounted on two running bogies of a typical design 2, which contains a spinal, two side, transverse, pivot, end and intermediate beams The upper plane of the frame is covered with a solid sheet, which is the floor of the cargo platform, on which two middle movable 3 are placed,

Fig. 1, 2 (each of the two parts are longitudinal) and the two extreme stationary bearing elements 4. The movable elements are made in cross-section in the form of non-equilateral triangular prisms. The slope of the sides of the prisms is selected depending on the design size of the diameters of the rolls, providing the most favorable conditions for resting the rolls on the supports. In order to limit the longitudinal and transverse movement of movable bed elements, stops 5, Fig. 3, 4, 6 of a prismatic shape are fixed on the floor of the frame, which also serve as guides for bed elements.

The installation of movable bearings on stops 5 in the required position for one or another standard size of rolls is carried out with the help of typical lifting mechanisms of metallurgical shops, which are used to load the rolls into the wagon.

The supporting planes of the sides of the bearings are lined with an elastic material to reduce the specific pressure on the rolls and avoid damage to the cold-rolled thin rolled sheet. with

To maintain the longitudinal movement of the rolls under the action of dynamic forces arising in the train during movement, the design of the useful model provides transverse beams 6, Fig. 1, 2, 5, which are fixed with pins on the longitudinal bearings. at

To protect the cargo from atmospheric precipitation, the wagon is equipped with a removable cap or a sliding sectional FU body.

З When the moving bodies are removed, the cargo platform of the wagon can be used for the transportation of rolled sheets in bundles.

The proposed useful model of the car corresponds to the conditions of production of car-building enterprises and the conditions of operation of specialized cars at metallurgical enterprises and on the entire network of railways with a gauge of 1520 mm. "

OJSC "Dniprovagonmash" developed design documentation for a new design of the car and produced its Z 70 prototype. Figure 1 shows a platform car for sheet steel in rolls, front view. Thin lines

With" lines show the rolls. Conventional lines show the protective cap.

Fig. 3 is the same as Fig. 1, 2, a cross section of the car. Thin lines show the roll.

The scheme of loading in one row is displayed. - In Fig. 4 - the same as in Fig. 3. Scheme of loading rolls in two rows. (se) Fig. 5 is the same as Fig. 3, 4. Scheme of loading rolls in three rows.

Fig. 6 is a cross-section of the longitudinal bed elements. A is a node shown in Fig. 3, when the movable bed elements are installed on fixed stops 5 to ensure the location of the rolls in one row. B - node shown in Fig.4. In this position, the lodgements ensure the placement of rolls in two and three rows. from Source of information 1. "Vagong", general course, edited by prof. V. V.

Claims (1)

The formula of the invention 6о 1. A platform car for sheet steel in rolls, containing a frame mounted on two running carriages, equipped with support beds for placing rolls on them along the car, which differs in that the two extreme beds, which are located along the side beams of the frame, are fixed fixed, and the two middle ones are movable to change the sizes between them and between the extreme bearings, ensuring the placement of rolls in one, two or three rows along the frame. bo 2. The platform car according to claim 1, which is characterized by the fact that the movable (replaceable) lozenges are oriented in the required position and are restrained from longitudinal transverse movement by means of prismatic stops attached to the floor of the frame. - s s IS) (o) h- - with . and? - se) 1 of 50 Ko) c 60 b5
