Description

Technical field

The technical solution relates to a mechanism for tilting the roof with one-sided vertical closing, especially on the roof of the wagon.

Background Art

With current solutions for tilting the roof over a circular path, the roof is not vertically placed on the neck of the chute and thus the roof is not closed over its entire length at the neck of the chute. This affects the tightness and stress of the roof.

In the case of roofs which, when closed, lie on the full length of the filler neck, several gearboxes are used for the roof tilting function on a non-circular path. In one particular embodiment, the roof tilt mechanism includes a steering wheel that is a timing shaft coupled to a gearbox, the gearbox input shaft is coupled to a crank, wherein the crank is coupled via a pivot pin to a connecting rod that is connected to the arm where the arm has two stops to support the connecting rod, then the opposite end of the arm is provided with a drawbar, the type of end of the drawbar being a rotatable mounting on the anchoring bracket of the seat of the whole mechanism, a bar attached to the tilting roof is attached to the upper end of the arm.

The essence of the technical solution

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

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

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 shows a diagram of the mechanism and Fig. 2 shows a gradual opening of the roof with a trajectory of movement.

Examples of technical solutions

The roof tilting mechanism 11 comprises an arm 1 of the roof 11, a lifting rod 2, an extraction rod 3, a rotary arm 4, a bearing 5, a control rod 6, a crank 7, a gear shaft 8, a gear 9, a hand wheel 10 and a roof Π.

Turning the handwheel 10 causes the crankshaft 7 to synchronously rotate at both ends of the wagon by means of the transmission 9 and the timing shaft 8. The rotary movement of the crank 7 is transmitted 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 slightly vertical lifting of the side of the roof 11 in the first opening phase, which passes over the neck of the chute when opened (Fig. 2b) ). Gradually, the rotational movement of the pivot arm 4 begins to be transmitted via the suction rod 3 to the roof arm 1. By rotating the roof arm 1, the roof 11 is then moved away with the trajectory on a circle outside the hopper opening (Fig. 2c, d). By closing the roof 11 in the final phase of the movement, a vertical closing of the roof 11 on the neck of the chute is ensured by a main prerequisite for sealing the roof 11 of the wagon.

In the first opening phase, the mechanism provides a sufficient vertical lift of the side of the roof 11 which, when opened, passes over the neck of the chute. In the second phase, the mechanism performs a smooth displacement of the roof 11 outside the trajectory through the circle. The entire roof opening and closing process is controlled by the handwheel 10. The timing shaft 8, which also serves as the synchronizing shaft, is located at the bottom of the wagon.

The mechanism for tilting the roof 11 with one-sided vertical closing comprises a handwheel 10 which is connected to the timing shaft 8 via a gear 9, at both ends of the timing shaft 8 there are cranks 7 connected to a control rod 6 which is connected to the lifting rod 2 at raising the roof 11 when opening at one edge of the neck of the chute, the opposite end of the lifting rod 2 is attached to the roof 11, the control rod 6 is also connected to the pivot arm 4, the pivot arm 4 is pivotally fixed in the first housing 5 and connected to the extraction rod 3 , the other end of which is connected to the arm 1, where the arm 1 is also connected to the second bearing 5a and the roof 11, all joints being articulated.
