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 supports 2 together with the plate 11 along the vertical guides 12 and the corresponding preliminary lifting of the roof 1, and then in the direction selected by the arrow 14 along the right power guide 13. The displacement of the plate 11 with the corresponding lifting of the roof 1 is limited by means 15, and Continuing after the nut 5, the movement of the roller bearing 4 along the right guide 13 selected by the arrow 14 leads to the rotation of the radial bearings 2 to the left. The possibility of rotation is provided by the sleeve 10, which is fixed at one end on the power plate 11, and its other end is placed in the opening of the jumper 9, located in the middle part of the radial supports 2. The roof 1 moves smoothly along the arc counterclockwise. The nut 5 continues to move along the screw 6, moving away from the gear motor 7, the roller bearing 4 slides along the right power guide 13 and, accordingly, continues to move to the left along the arc of the radial supports 2. The roof 1 opens completely, occupying an extreme position close to parallel to the left side wall of the car body. The limit switch is activated (not shown in the drawing), de-energizing the gear motor 7. The loading and unloading opening is fully accessible for work on the right side of the car (Fig. 2). To carry out these works on the other (left) side of the car, the operator, before starting the electric drive of the motor-reducer 7, moves the arrow 14 to the right to slide the roller bearing 4 along the other (left) guide 13, and the full opening of the roof 1 to the right side occurs according to the above description.

Roof 1 is closed in reverse order. When the direction of rotation of the motor-reducer 7 is changed, the screw 6 starts to rotate in the opposite direction, the nut 5 moves along the screw 9, approaching the motor-reducer 7, and the radial supports 2 begin to move (provided by the sleeve 10) in an arc in the opposite direction - clockwise . The roof 1, following the radial supports 2, is also displaced along the arc in the opposite direction. The roller bearing 4 slides down along the corresponding curved part of the guide 13, the roof 1 takes an elevated position above the car and then, together with the power plate 11, falls along the vertical guides 12 until it is completely closed. The limit switch is activated, de-energizing the motor-reducer 7.

The nodes of the mechanism for moving the roof 1 are identical at both ends of the car and are mirrored.

Synchronization of the rotation of the shafts of the motor-reducers 7 can be provided by frequency converters, counting the revolutions of rotation of the corresponding electric motors.

Thus, the claimed set of features of the utility model ensures the opening of the roof to the full width to any side with the combination of the stages of lifting and turning the roof in a single technological cycle and, accordingly, ensures the achievement of the claimed technical result - simplification and acceleration of loading and unloading operations from the side opposite to that chosen for full roof opening.
