EP1591334B1 - Anti-theft device on freight vehicles, especially on vehicles with sliding side panels - Google Patents

Abstract

A toggle lever has a joint hook fastened to a central portal of a central support. A closing mechanism is inserted into a lock yoke and a pin is inserted into an upper bore or a lower bore to lock sliding panels together. The closing mechanism is removed from the lock yoke and the pin is removed from the bore to open the sliding panels.

Description

The invention relates to a device for securing sliding walls and / or hoods to freight wagons, in particular to sliding wall wagons, wherein the cars are composed of a base frame, the end walls, the sliding walls and a central portal and the sliding walls can be pushed over each other by means of a release mechanism.

Sliding wall wagons have been used for many years in rail freight transport. Here, a variety of locking devices for the sliding walls are known. When opening a sliding wall, the sliding wall is after the Ausstellprozess on the wall leading rail and can be moved in the car longitudinal direction to the center of the car to release the loading opening. If the vehicle is on a downgrade or is loaded asymmetrically, u. U. unroll the sliding wall automatically. During the closing process, the sliding panel is pushed in the longitudinal direction of the car to the front wall where it is buffered in the end position. Due to the buffering, it can happen that the sliding wall has to be removed again from the end position and has to be pushed back again in order to be able to end the closing process. These unwanted movements of the sliding wall are intended by locking devices as in the DE 198 50 805 A1 , of the DE 43 19 984 A1 and the DE 198 20 021 C2 be prevented.

Although all of the above locking devices secure the sliding walls against accidental movement by pawls, swiveling latches and rotatable pawls, but with them it is not possible to effectively provide the sliding walls against breaking and / or levering with a theft protection.

• Blockierung der Gestänge für die Betätigung der Schiebewände, die an den Stirnwänden des Güterwagens angebracht sind, mittels eines Schlosses. Eine Bedienung des Schlosses von der Laderampe aus ist nicht möglich. Dieses System ist nach neuesten Erkenntnissen jedoch dadurch manipulierbar, dass das Gestänge zu den Schwenkwellen hin gelöst und somit die Schiebewände geöffnet werden können.
• Blockierung gegen Ausschwenken der Schiebewände, in dem ein Schloss unterhalb der Schiebewand an der Laufschiene gelenkig angebracht und in einer Öse an der Mittelsäule festgelegt ist. Auch dieses System ist nicht von der Laderampe aus bedienbar. Weiterhin kann bei diesem System auch durch die U-förmige Ausführung des Schlosses die Öse, in welche das Schloss festgelegt ist, mit einem Schleifwerkzeug durchtrennt werden, so dass eine Blockierung durch das Schloss nicht mehr vorhanden ist.

As previously known fuses as theft protection, the following systems exist:

• Blocking of the linkage for the operation of the sliding walls, which are attached to the end walls of the freight car, by means of a lock. Operation of the lock from the loading ramp is not possible. However, this system can be manipulated according to the latest findings, that the linkage to the pivot shafts solved and thus the sliding walls can be opened.
• Blocking against swinging the sliding walls, in which a lock is hinged below the sliding wall on the running rail and fixed in an eyelet on the center column. Also this system is not operable from the loading ramp. Furthermore, in this system, by the U-shaped design of the castle, the eyelet into which the lock is set, are cut with a grinding tool, so that a blockage through the castle is no longer available.

The invention has for its object to provide sliding wall wagon with an effective theft protection, which simply and effectively prevents unauthorized opening of the sliding walls, the anti-theft device should be permanently attached to the wagon, so that degradation and / or loss is avoided by misplacing / losing and operation of the system can be done from the loading dock.

• im geschlossenen Zustand der beiden Schiebewände (14;15) der Schlossbügel (6) mit der Aussparung (20) eine eine Bohrung (18) aufweisende untere Öse (17) umgreift, durch die der Schließbolzen (9) geführt ist und
• zum Öffnen der beiden Schiebewände (14;15) der Schlossbügel (6) nach seiner Entriegelung durch den Schließmechanismus (12) und dem Ziehen des Schließbolzen (9) mittels Gelenkstück (5) über die Gelenköse (4) nach oben zu klappen ist und der Schlossbügel (6) mit der Aussparung (20) dann eine eine Bohrung (18) aufweisende obere Öse (19) umgreift, durch die wiederum der Schließbolzen (9) geführt ist.

This is inventively achieved in that
on the web plate (1) of the central portal (2) of the sliding wall wagon (3) a hinge eye (4) is fixed, in which a hinge piece (5) engages with a lock bracket (6), wherein the lock bracket (6) with a preferably elongated recess ( 20) and a bore (8) passing therethrough, through which a locking bolt (9) is guided, which has a recess (11) on its shaft (10) into which the sliding walls (14, 15) engage in the closed state in the lock bracket (6) built-in locking mechanism (12) engages, wherein

• in the closed state of the two sliding walls (14; 15) of the lock bracket (6) with the recess (20) surrounds a lower eyelet (17) having a bore (18) through which the locking pin (9) is guided and
• to open the two sliding walls (14; 15) of the lock bracket (6) after its unlocking by the locking mechanism (12) and the pulling of the locking pin (9) by means of hinge piece (5) via the hinge eye (4) to fold up and the Lock bracket (6) with the recess (20) then a hole (18) having upper eyelet (19) engages, through which in turn the locking pin (9) is guided.

The closing mechanism (12) in this case has a lock cylinder (13), which engages in the closed state in the recess (11) of the shank (10) of the locking bolt (9).

In a preferred embodiment of the invention, it is also possible on the lock bracket (6) to attach a recess (7) in which the locking mechanism (12) is arranged.

Furthermore, it is possible that the lock bracket (6) in the upper eyelet (19) may remain when the freight car is transported unloaded or must be supplied to a plant for maintenance.

Advantages of the invention:

• the sliding wall can only be opened when the hinged closure device is necessarily fixed to the upper eyelet (18)
• due to the hinged design, the closure device can not be removed, misplaced or otherwise lost
• the closure device ensures effectiveness even when manipulated on the linkage of the actuator for the sliding walls
• The locking devices can also be easily and easily opened from a ramp without restrictions
• in a determination of the closure device on the upper eyelet (18) this can be used without lock fuse for normal transport
• A maximum of two locking devices per wagon are necessary

• FIG. 3 - The device in the closed state
• FIG. 4 - The device in the folded state
• FIG. 5 - The device in the open state
• FIG. 6 - The device with closed-shaped eyelet

The FIG. 1 shows a sliding wall cart 3 in longitudinal view.
The sliding wall cart 3 has on the web plate 1 of the central portal 2 a hinge eye 4. A lock bracket 6 is attached to this articulation lug 4 via a joint piece 5 ( FIG. 2 ). At the lower end of the lock bracket 6, a bore 8 is mounted on one or both sides, by the closed walls of the sliding walls 14; 15 a locking pin 9 is guided. This locking pin 9 has on its shaft 10 a recess 11, in the closed state of the sliding walls 14; 15 of the lock cylinder 13 engages ( FIG. 6 ). The recess 20 having a lock bracket 6 surrounds in this case a mounted in the lower region of the center column 1 lower eyelet 17 with bore 16. Through the bore 16 of the lower eyelet 17 of the shaft 10 of the locking pin 9 is guided and the locking mechanism 12 is actuated. By the engagement of the lock cylinder 13 in the recess 11, the locking pin 9 is then secured against unauthorized removal, so that the sliding walls 14, 15 can not be opened.
If the sliding walls 14, 15 are to be opened, first the locking mechanism 12 must be unlocked, so that the locking cylinder 13 releases the shaft 10 of the locking bolt 9 (FIG. FIGS. 3, 4 and 5 ). Thereafter, the locking pin 9 is pulled and the lock bracket 6 are folded by means of hinge piece 5 upwards until the recess 20 which also attached to the center column 1 upper eyelet 19 includes. Then the locking pin 9 is again guided through the bore 18 of the upper eyelet 19. Only now can one of the two sliding walls 14; 15 are opened.
