Especially for sliding roofs and walls of freight wagons Utvikningsanordning särskilt för godsvagnar skjuttak och -vägg

The invention relates to a sliding roof and 5-wall prewinding device according to claim 1.

Sliding roofs and walls of freight wagons follow two basic principles. In most cases, a solution is used in which the sliding ceilings and walls are rotated during the pre-rotation to a circular path about the guide 10 axis.

A running rail mounted for longitudinal displacement of roofs and sidewalls is cut off from the swiveling area to receive the swiveling member. However, the tread openings must cross the trolley where the roof or side wall is open: 15 goes over the closed one. Several solutions are known here. In DE 4006 657, a guide rail is rotatably disposed over the opening and is moved by means of stops mounted on the steering shaft, is brought into contact with the running rail and can be spaced by a spacer from the pivotable pivoting member.

In DE 3524 721 the opening of the swiveling area of the running rail is crossed by a fixed guide rail. When the swiveled wall passes over the swinging area of the fixed roof in its closed position, its impeller groove leaves the impeller and: T: The cylindrical portion disposed on the impeller side rotates on the auxiliary rail and thereby provides support.

»* ·; A disadvantage of the solutions shown is that the horizontal and vertical distance that is reflected when rotated is decisively determined by the distance of the pivoting member to its pivot point.

An optimal solution of the structure of the pre-turning device is often not possible due to environmental conditions, longitudinal beams, position of the steering shaft, shape of the impeller bracket, free space of the roof single-sided sidewall and open side or wall loading and unloading ramp. A further disadvantage is the large number of components and their complex structure. A disadvantage of the solutions presented is the very precise installation required by the auxiliary rails.

From DDR 288 354 there is known a solution of a pre-rotation device in which a gripper is moved on 10 motion paths with straight and associated circular arcs. This makes it possible to place the roof or sidewall on a continuous running rail from above and move it without auxiliary rails. A disadvantage of this solution is that a roller chain is used as the pivoting mechanism, which in the transport position of the roof or sidewall is heavily loaded and starts to slip. In addition, the Shark-15 is the complex securing of the roof or side wall during turning and the unreliable construction of the gripper.

The object of the invention is to create such a slider for freight wagons. . a pivoting device for sidewalls and sidewalls, wherein the pivoting movement of the pivoting member between the closing and / '', 20 pivoting positions extends * · t depending on the kinematic dimensions of the articulated chain. ·. : the connection curve, roof or side parts are secured continuously and reliably * · •. ·: During the turn, the number of components decreases and the structure alone:: ': simplifies and also reduces economic costs.

The problem is solved essentially in accordance with the features of the claim, that is, by means of a '·: ·' articulated link between the running rail and the web of the longitudinal beam, moving the side-wall supporting pivot in a curved path:. · .; whereby four or three joints of the mechanism, two of which are formed by '· ·: curved joints, are connected by pivotal joints.

15 The link chain is driven by a torsion rigidly mounted palm 4 on the steering shaft 3. During the pivoting of the sidewall or ceiling, the pivoting member 7 is disposed on the coupling 6 and the coupling 6 is pivoted on the one hand on the crank 4 and on the lever arm 10 pivotally mounted on the underframe. '20 so that it surrounds the sheath surface of the pivoting member 7 and leaves open only a longitudinal opening 13 allowing the passage of the connecting member 14 between the pivoting member 7 and the lever arm 10. The ceiling or sidewall is thus reliably secured from its stationary position in the closed position and the fold-out hinge. The design of the kinematic dimensions of the individual articulation links 25 thus allows the impeller carrier 11 and the impeller 17 to be lifted onto the continuous running rail 1. According to another feature of the invention according to Fig. 4, the continuous running rail 1 has vertical pivots: in the longitudinal direction of the wagon.

; The feature of Figure 3 of the invention consists in that the running rail 1 is provided with an anti-climb rail 21 which engages the anti-climbing part 20 permanently mounted on the sliding 114205 4 wall transfer mechanism 23 and ensures that the roof or sidewall impeller 17 does not rise from the running rail. 1. The anti-slip rail 21 has openings in the pivoting area of the sliding wall transfer mechanism 23 which engage with the anti-slip portions 20 of the transfer mechanism 23 and allow for inward and outward rotation of the impeller carrier 11. Another feature of the anti-slip portions 20 is their placement in the sliding wall displacement mechanism 23. The dimensions a and b defining a roof or sliding wall anti-slip are 10 different from the dimensions a 'and b' of another roof or sidewall on the same longitudinal side.

The exemplary embodiment of Fig. 2 shows a three-link articulated chain having two articulations a pivotal joint and a curved joint. A crank 4 mounted permanently on the steering shaft 3 is connected by a joint 5 to a lever 24. The lever 24 is integrally associated with a pivoting member 7. A further wheel 25 is mounted on the lever 24 and extends coincidently with the oblique 29 of the impeller 17. Lever 24 curves for steering,. t at the bottom of track 26 is limited by locking stop 27.

:: · *! 2o • *. ·. : The invention is characterized in that a simply shaped structural ♦ <«• · • sin creates a pre-turning device which allows the roof or side wall to be placed continuously on top of the running rail 1 without the use of auxiliary rails to reliably secure the roof or side - 25 semiconductors in closed and pivoting position and during pivoting, and .. ii * that said device can be easily mounted and secured to a freight wagon 30.

Due to the fact that the sliding wall displacement mechanism 23 is adapted to kinematic dimensions: -: /: 30, a variable shape is also advantageous. In this way it is possible '...: to open the sliding wall or roof of the loaded freight wagon 30 without any problems even if 114205 5 loads have been wedged during transport. A further advantage may be the protected positioning of the folding device, mainly the steering shaft 3, under the car body.
