Description

Technical field

The technical solution relates to a mechanism for tilting the roof with a one-sided vertical closure, in particular to the roof of a wagon.

BACKGROUND OF THE INVENTION

With the present solutions allowing the roof to be tilted along a circular track, there is no vertical placement of the roof on the opening of the chute and thus the roof, when closed, does not lie on its entire opening in the opening of the chute. This adversely affects the tightness and stress of the roof.

For roofs which, in the closed state, lie along the entire length of the chute opening, several gearboxes are used for the function of tilting the roof along a non-circular track. In one particular embodiment, the roof tilting mechanism comprises a steering wheel that is coupled to a transmission by a timing shaft, the transmission input shaft is connected to a crank, the crank being connected to a connecting rod via a pivot, which is connected to an arm where the arm has two stops abutting the connecting rod, then the opposite end of the arm is provided with a drawbar, the other end of the drawbar being a rotatable bearing on the anchor bracket of the bearing of the whole mechanism, at the upper end of the arm is fixed rod connected to the folding roof.

The essence of the technical solution

The solution relates to a mechanism for opening the roofs of wagons for the transport of various substrates. The solution of the mechanism ensures, in the first opening phase, a sufficient vertical lifting of the side of the roof which, when opened, passes over the neck of the chute. In the second phase, the mechanism performs a smooth displacement of the roof outside the chute with a trajectory along the circle. The entire roof opening and closing process is controlled by a handwheel. The timing shaft, which also functions as a synchronizing shaft, is located at the bottom of the wagon.

This design allows only one gearbox to drive the entire mechanism.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows a schematic of the mechanism and Figure 2 shows a progressive roof opening with a trajectory of movement.

EXAMPLES

The roof lift mechanism 11 comprises a roof arm X, a lift rod 2, a suction rod 3, a pivot arm 4, a bearing 5, a control rod 6, a crank 7, a timing shaft 8, a gearbox 9, a handwheel 10 and a roof 11.

By rotating the handwheel 10, by means of the gearbox 9 and the camshaft 8, the cranks 7 are rotated synchronously at both ends of the car. The pivoting movement of the crank 7 is transferred via the control rod 6 to the pivot arm 4. The initial position of the pivot arm 4 together with the lifting rod 2 ensures a slight vertical elevation of the side of the roof XX which opens over the opening of the chute during opening (Figure 2b) . Gradually, the rotational movement of the pivot arm 4 begins to be transmitted via the suction rod 3 to the roof arm X of the roof XX. By rotating the roof arm X, the roof 11 is then moved with a trajectory along a circle outside the chute opening (Figure 2c, d). By closing the roof 11 in the final phase of the movement, the roof 11 is clamped vertically on the neck of the chute opening, the main prerequisite for sealing the roof 11 of the wagon.

In the first opening phase, the mechanism provides a sufficient vertical lifting of the side of the roof 11 which passes over the opening of the chute during opening. In the second phase, the mechanism performs a continuous displacement of the roof 11 outside the chute with a trajectory along the circle. The entire opening and closing process of the roof 11 is controlled by means of a handwheel 10. The timing shaft 8, which also serves as a synchronizing shaft, is located at the bottom of the car.

The roof lift-off mechanism 11 with a one-sided vertical closure comprises a handwheel 10 which is connected to the timing shaft 8 via a gearbox 9, at both ends of the timing shaft 8 there are cranks 7 connected to a control rod 6 which is articulated with a PRI 2

The roof end 11 is connected to the roof 11, the control rod 6 is also connected to the swivel arm 4, the swivel arm 4 is rotatably fixed in the first bearing 5 and connected to the roof. a suction rod 3, the other end of which is connected to the arm J, wherein the arm J is also connected to the second bearing 5a and the roof 11, all connections being jointed.
