RU213313U1RU 213313 U1RU213313 U1RU 213313U1RU-213313-U1

Abstract

The utility model relates to the field of railway transport, in particular to car building and transportation of goods. The technical result achieved by the utility model is the acceleration and simplification of loading and unloading operations due to the possibility of opening the roof to any side for the entire width of the car, ensuring that the stages of its lifting and turning in a single technological cycle are combined. The car contains a sliding roof (1) and a mechanism for its movement. In this case, the roof (1) is provided with radial supports (2) on each transverse side, and the specified movement mechanism contains a hinge assembly having the first sleeve (3) with a roller bearing (4) attached to one of the faces of the nut (5) under the screw ( 6) on the shaft of the motor-reducer (7), which is fixed on the lower transverse beam (8) of the car body. The radial supports (2) have a jumper (9) in the middle part with a hole for the second bushing (10) and are fixed with the possibility of rotation on the power plate (11) installed with the possibility of limited displacement along the vertical guides (12), to the lower part of which and the lower transverse beam (8) of the car body is attached to two versatile power S-shaped guides (13). The first bushing (3) is installed in a hole made in the lower part of the radial bearings (2) with the possibility of movement of the roller bearing (4) along one of the indicated power guides (13) depending on the direction of movement of the roof (1) selected by the movable arrow (14) . 2 ill.

Description

Technical field The utility model relates to the field of railway transport, in particular to car building and transportation of goods. State of the art A similar car is known that uses a design with a sliding roof (B.C. Dormidontov "Design of a hopper car for transporting grain with a sliding roof", the magazine "Transport of the Russian Federation" No. 3 (58) 2015). In the analogue device, the roof has a fixed part and a movable part, which is pivotally attached to the car body with the help of swivel racks and is driven by a mechanism for moving it. In this design, a gap is formed between the movable and fixed parts of the roof, which reduces the tightness. In this case, the loading and unloading of goods is limited by the width of the drop-down opening, that is, part of the width of the wagon. These shortcomings are eliminated in the decision on the patent RU No. 208649 dated 10/22/2021, which is selected as a prototype. In the prototype device, the entire roof is shifted and its opening is provided for the entire width of the car. At the same time, the stages of lifting the roof and turning it open to the full width of the car are carried out in a single technological cycle. However, in the prototype, the roof moves only in one direction and the disclosure occurs only in one direction, which is a limitation for loading and unloading operations. The problem solved by the utility model is the development of a structure that provides displacement of the roof to any side with the possibility of versatile opening to the full width. The technical result achieved by the utility model is the acceleration and simplification of loading and unloading operations due to the possibility of opening the roof to any side for the entire width of the car, ensuring that the stages of its lifting and turning in a single technological cycle are combined. The subject of the utility model is a car containing a roof and a mechanism for moving the roof from each end side of the car body, the roof from each transverse side is provided with radial supports, and the mechanism for moving the roof contains a hinge assembly having a first sleeve with a roller bearing attached to a screw nut on the shaft of the motor-reducer, which is fixed on the lower transverse beam of the car body, the radial bearings have in the middle part a jumper with a hole for the second bearing sleeve with the possibility of rotation and are fixed on the power plate, mounted with the possibility of displacement along the vertical guides, to the lower part of which and the lower transverse two versatile power S-shaped guides are attached to the beam of the car body, while the first bushing is installed in a hole made in the lower part of the radial bearings with the possibility of movement of the roller bearing along one of the indicated power guides, depending on the direction of movement chosen by the moving arrow roof. This combination of features ensures the achievement of the claimed technical result. Implementation of the utility model The essence of the utility model is illustrated by drawings (Fig. 1 - the closed state of the roof, Fig. 2 - the roof is fully open). The drawings show the sliding roof 1 of the car and the mechanism for its movement from each end side. At the same time, the roof 1 is provided with radial supports 2 on each transverse side, and the specified movement mechanism contains a hinge assembly having the first sleeve 3 with a double roller bearing 4 attached to one of the faces of the nut 5 under the screw 6 on the shaft of the motor-reducer 7, which is fixed on the lower transverse beam 8 of the car body. The radial bearings 2 have in the middle part a jumper 9 with a hole for the second bushing 10 and are fixed (through the bushing 10) with the possibility of rotation on the power plate 11, installed with the possibility of limited displacement along the vertical guides 12, to the lower part of which and the lower transverse beam 8 of the body two versatile power S-shaped guides 13 are attached to the car. The first sleeve 3 is installed in a hole made in the lower part of the radial supports 2 with the possibility of moving the roller bearing 4 along one of the indicated power guides 13, depending on the selected movable arrow 14 (Fig. 2) direction of roof movement 1. Description of the utility model In the initial state, the roof 1 is closed. The operator by the position of the movable arrow (bridge) 14 selects, for example, to the left, the direction of displacement of the roof and starts the electric motor-reducer 7, which is fixed on the lower transverse beam 8 of the car body. The gear motor 7 rotates the screw 6. The nut 5 moves along the screw 6 in the direction from the gear motor 7. Since the nut 5 is connected to the sleeve 3, on which the roller bearing 4 is fixed on the other side, simultaneously with the movement of the nut 5, the roller bearing starts to move 4, first upwards, providing displacement of the suppo
