UA8657U - Flat-car for rolls of metal sheets - Google Patents

Abstract

Flat-car for transportation of the rolls of metallic sheets contains frame mounted on two carriages equipped with the supports in the form of welded prisms of triangular form in the section, which have transverse arrangement on the railroad car. In this case, at least two supports are mobile along the frame of railroad car.

Description

Description of the invention

The useful model of the proposed wagon belongs to railway transport, namely, to specialized 2 freight wagons for the transportation of rolls of hot-rolled steel sheet. If the wagon is equipped with a cap to protect the cargo from atmospheric precipitation, it can be used to transport rolls of cold-rolled steel.

Transportation of rolled steel sheets in rolls is now carried out by universal and specialized wagons. The metallurgical industry in the world, including in Ukraine, is constantly expanding the range of standard sizes of 70 rolls, increasing their size and weight, which leads to greater specialization of railway transport and a decrease in the efficiency of the use of existing specialized wagons. From this point of view, it should be noted that the efficiency of the operation of specialized wagons for transporting rolls is significantly affected by the location of the rolls in the wagon, that is, the orientation of the axis of the rolls relative to the longitudinal axis of the wagon - along, across or vertically. In terms of carrying out loading and unloading operations and achieving the minimum 72 dynamic load of the main load-bearing units of the car during transportation, the transverse arrangement of rolls is the most appropriate.

For this, specialized wagons are made with recesses in the floor or are equipped with supports that form transversely located beds (chutes) for placing rolls.

The problem is that rolls of rolled steel differ significantly in size and weight, due to smoke, to ensure a stable position from rolling when they are transversely arranged, the bed frames on the wagons must be of the appropriate size. This leads to the fact that the carrier must have several modifications of wagons to ensure the transportation of the entire standard size range of rolls, which reduces the efficiency of operation of the rolling stock.

The purpose of the proposed design of the utility model is to expand the specialization of the wagon, i.e., due to the constructive execution of the supports that form the bedsteads, to ensure the possibility of transporting a larger number of standard sizes of rolled sheet steel rolls by wagon, thereby reducing operational costs for transportation.

The proposed wagon provides transportation of rolled steel rolls with a diameter from 800 to 2100 mm and a sheet width of 9UOOmm and more. -

Well-known specialized wagons for transporting steel in rolls: Yu

Wagon for transportation of cold-rolled steel with transverse arrangement of rolls model 12-9008 (1).

Such wagons provide transportation of rolls with a diameter from 1100 to 1600 mm; "Railroad ke, a platform for the transportation of metal rolls or metal scrap", Great Britain (2). p

The platform car belongs to the class of short-base car designs, it is a frame 1, Fig. 1, 2, 3, 325 installed on two trolleys 2, which contains a backbone, two side, pivot and transverse beams, has a typical coupling and braking equipment. On top of the frame, six transverse supports Z are installed in the form of welded prisms of triangular cross-section, the sides of which form bearings for rolls. Four supports are rigidly connected to the frame, and the other two 4.6 are movable, fixed on the frame with the help of pin stops b installed on the side tanks of the frame 1. Movable supports make it possible to create bed frames with larger widths, necessary for 50 placement in of rolls of the maximum diameter (1400-2100 mm) of Fig. 3, which cannot be placed in the s lodgements formed by supports immovably fixed on the frame. Movable supports 4.6 are moved on the frame and are set to the required size of the beds with the help of cranes, which are used at metallurgical enterprises to load rolls into wagons.

The number of fixed and movable supports is selected based on the most efficient placement of rolls of different sizes. The supports that form the beds are equipped with movable stops from the transverse movement of the rolls 7, Fig. 1, 2, 3

The location of medium-sized rolls in diameter on the wagon is shown by a dashed line. i-th In Fig. 2 - the same, top view. Rolled rolls are shaded with thin lines. "And 20 in Fig. 3 is the same as in Fig. 1. Movable supports 4,6 are installed closer to the consoles of the car, which ensures the placement of rolls of the maximum size in diameter.

The proposed design of the car corresponds to the conditions of production of car-building enterprises and the conditions of operation of specialized cars throughout the network of industrial and main railways with a gauge of 1520 mm.
