SK6689Y1 - Mechanism supported wagon roof which opens the path curves - Google Patents

Abstract

Mechanism supports are roofs consist of torsion bars (1) connected to the tensioning mechanisms (2) fixed to the ends of the roof, and associated with the arm (3) with a support pulley (4). During the opening / closing of the roof is a support pulley (4) by means of arms (3) biased by torsion bars (1) of pushed track(14) formed on the side wall of the wagon and thereby pushing away from the roof side panel, which it supports.

Technical field

The mechanism relates to covered wagons for the transport of bulk materials, for example for the transport of grain, with a tilting roof not moving in a circle but along a curve.

BACKGROUND OF THE INVENTION

A known solution is to support the folding roofs of covered rail freight wagons moving towards the side of the wagon along a circle. For example, support rollers mounted on the roof are commonly used. When opening the roof, the rollers roll along a guide formed on the side of the wagon, thereby supporting the wagon roof and preventing it from bending. For this purpose, one support roller in the center of the roof or several support rollers is evenly distributed in the roof.

The second type of solution is to support the tilt roof moving along the curve, not the circle. This mechanism supports the roof which is first raised or lowered. folds down and then swings along the sidewall. The mechanism supports the roof over the entire roof travel path. This mechanism works automatically when supporting the roof.

The essence of the technical solution

The essence of the technical solution according to the present utility model is represented by the mechanism of supporting the wagon roof opening along the curve path. This mechanism is located on the roof of the wagon and contains two torsion bars, which are supported at their ends on the edge of the roof by tensioning mechanisms, and in the middle there is at least one torsion bar connected by arm, torsion bars are equipped with outer square at their ends. a square with a fork that rests on the swivel plate, the swivel plate is clamped on the eye bolt and is pressed by the nut, in the eye of the bolt is the pin fixed in the body of the tensioning mechanism; the arm connects the torsion bar through the ends of the shoulder straps are connected by an axle to a support roller moving along the curve path, the torsion bar being supported along its length by beds fixed to the roof structure. Tipping resp. the opening and closing of the roof is carried out by means of the control means through the mechanism and the arm, the movement to the other side of the wagon being transmitted by a transmission.

During the roof opening, the boom support roller rolls along the track formed on the side of the wagon. The roof is thus supported during the entire roof lift.

The advantage of this support is to reduce the sag of the roof and to damp the roof oscillation during opening / closing. The advantages of this roof support are particularly apparent with extremely long roofs. The automatic operation of the mechanism is also an advantage.

EXAMPLES

Mechanism for supporting the wagon roof opening along the curve path. This mechanism is located on the roof of the wagon and comprises at least one torsion bar 1, which is supported at its end at the roof edge by a tensioning mechanism 2 and in the middle part the torsion bar 1 is connected by an arm 3; the tensioning mechanism 2 comprises an internal square 13 with a fork 6 which is supported by the rotating plate 7, the rotating plate 7 being fitted onto the eye bolt 8 and pressed by the nut 10, in the eye of the bolt 8 the pin 11 is fixed , to the arm 3 the torsion bar 1 is connected by means of outer squares 12, which are anchored in the inner squares 13 connected to the straps T of the arm 3, the ends of the straps T of arm 3 are connected by an axle it is supported along its length by beds 5 fixed to the roof structure.

Mechanism for supporting the wagon roof opening along the curve path. This mechanism is located on the roof of the wagon and comprises two torsion bars 1 which are supported at their ends at the edge of the roof.

In the middle part, the two torsion bars 1 are connected by an arm 3, the torsion bars 1 are provided at their ends with an outer square 12, the tensioning mechanism 2 comprises an inner square 13 with a fork 6, which rests on the rotary plate 7, wherein the turntable 7 is clamped onto the eye bolt 8 and is pressed by the nut 10, in the eye of the bolt 8 the pin 11 is fastened in the body of the tensioning mechanism 2, the arm 3 connects the two torsion bars 1 via the outer squares 12 13 connected to the strips 3 / arms 3, the ends of the strips 3 [arms 3 are connected by an axle to a support roller 4 moving along the curve path 14, the torsion bars 1 being supported along their length by beds 5 fixed to the roof structure.

Tipping resp. the opening and closing of the roof is carried out by means of the control means O through the mechanism M and the arm R, the movement to the other side of the wagon being transmitted by the transmission P.

During opening of the roof, the support roller 4 of the arm 3 rolls along a track 14 formed on the side of the wagon. The roof is thus supported during the entire roof lift.

Tightening / loosening the nut 10 increases / decreases the prestressing of the torsion bars 1 and thus the strength of the roof support. During the opening / closing of the roof, the support roller 4 is pushed by the arm 3 with prestressed torsion bars 1 onto the track 14 formed on the sidewall of the wagon, thereby pushing the roof away from the sidewall, thereby supporting it.

The support can be provided with at least one arm 3 with a support roller 4.

Industrial usability

The roof support mechanism is suitable for roofs of wagons of special types of freight railway wagons for transporting loose materials with a roof moving along a curve, the roof being extremely long.
