Abstract

A caging device for sliding side panels and covers of wagons for arrestment and unlocking sliding side panels or covers in longitudinal direction of the wagon in the end positions, which consist of the interlock and finger. On the running gear (8) of the sliding wall (4) is prepared a locking pin (9) oriented in the wagon's transverse direction and a run-on lever (10) with a guide nose (12) is attached by a pivot (16') to a locking pawl (11) which is provided with a recess (14). The locking pawl together with the run-on lever is attached by a further pivot (16) to the body of the wagon, and the pivoting ranges of the lever and pawl are limited by stops (13, 13').

Description

Technical field

The invention relates to a locking device for sliding walls or hatch roofs of freight wagons.

BACKGROUND OF THE INVENTION

The sliding wall latches of the freight wagons fix the sliding walls or hatches in certain positions in the longitudinal direction of the wagon. When opening the sliding wall, the sliding wall is located after the planting process on a rail that guides the walls and can be moved in the longitudinal direction of the wagon approximately to the center of the wagon to release the loading opening. Under certain circumstances, the sliding wall may start to move spontaneously when the vehicle is on an inclined track or is unbalanced. When closing, the sliding wall in the longitudinal direction of the wagon moves up to the front wall and is caught there in the end position. Upon engagement, it may happen that the sliding wall has to be retracted from the end position and retracted again in order to complete the closing. The unintentional movement of the sliding wall is to be prevented by locking devices. In the ORE report B12 / RP48, page A.2 / 11, a locking device is provided which automatically secures the sliding wall in the end position at the front wall and in the fully extended position against longitudinal displacement. The locking device consists of a movable pawl and a thumb, the pawl being located on the lower carrier of the sliding wall and the thumb on the underside of the carriage in both end positions. In this embodiment, the expensive and expensive arrangement of the movable pawl in the lower strip of the sliding wall is disadvantageous, since it must be opened and then closed again in order to use the actuating rod. The cross-sectional profile of the lower wall support often does not allow such weakening. Furthermore, the arrangement on the lower wall support is disadvantageous in that greater clearances arise due to manufacturing errors on many individual parts, by the elastic behavior of the components starting from the rail level up to the latch. Continuous functional safety is not guaranteed. The sliding wall lock can only be unlocked by using a latch and simultaneously sliding the wall. This means for the operator that he has to move the wall with one hand and pull out the latch with the other hand, or move the wall with both hands and pull out the latch with his feet. This lengthy movement of the movements is physically strenuous for the operator, and the aforementioned disadvantages have led to the locking device not being able to be pushed on wagons with sliding walls.

SUMMARY OF THE INVENTION The object of the present invention is to provide a locking device which securely fixes the sliding wall to the underside of the car, does not weaken the supporting parts of the sliding wall, consists of a small number of individual parts, avoids greater clearances, guarantees long-term functional safety and guarantees an advantageous movement for the operator.

SUMMARY OF THE INVENTION The present invention relates to a latching device for sliding walls and hatch roofs of freight wagons for arresting and releasing sliding walls or hatches in the longitudinal direction of the vehicle at end positions consisting of a latch and thumb, the thumb and latch corresponding to each other in the end position; a sliding wall mechanism is attached to the carriage, and the diac-inch drive lever is pivoted via a swivel joint to a locking pawl provided with a recess, the locking pawl together with a starting lever which is movably arranged on the locking pawl the pivoting joint pivoted to the wagon body and the deflection regions of the drive lever and the locking pawl are limited by stops.

The start lever can be rigidly attached to the locking pawl and the locking pawl is held in the locked position by the energy storage elements.

The arresting pin can be rigidly attached to the underside of the car and the start lever and the locking pawl are pivotably attached to the sliding wall movement mechanism via the pivot joint.

According to a preferred embodiment, the locking pin can be mounted on the lever via a pivot joint pivotally arranged on the underside of the carriage and a locking pawl provided with a guide thumb and a recess is arranged on the movement mechanism of the sliding wall via the pivot joint.

According to another embodiment, the arresting pin may be mounted on the lever, pivotally mounted on the sliding wall movement mechanism via a pivot joint, and the locking pawl provided with a guide thumb and recess is pivotally mounted on the underside of the car through the pivoting joint.

In the following, an exemplary embodiment of the invention will be explained by means of the figures.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the main subassemblies 1, the front wall 2, the central portal 3, the sliding wall 4 are shown from the wagon with sliding walls. At least one of the sliding walls 4 is opened for loading and unloading the wagon. For this purpose, the ejection device 5 according to FIG. 2, 3 and 4, the sliding wall 4 swings outwards and is mounted on the rail 6. Thereafter, the sliding wall 4 may slide in the longitudinal direction of the wagon until about half of the longitudinal side of the wagon is released. When closing the longitudinal side of the wagon, the sliding wall 4 slides in the direction of the end wall 2 until it reaches the end position according to FIG. 2 and 5 does not strike the bumper 7. The locking device 4 prevents an unintended movement of the sliding wall 4. For this purpose, a locking pin 9 is rigidly attached to the movement mechanism 8 of the sliding wall 4. This locking pin 9 lifts the start lever 10 by means of a guide thumb 12 when the sliding wall 4 enters the end position. A locking latch 11 is simultaneously raised by a stop 13 'disposed on the drive lever 10 in such a way that the stop 13' can abut the upper side of the locking latch and thereby limit the lowest position of the drive lever 10 on the locking latch 11. positioned pivotably via a pivot joint 16 at the bottom 1 of the wagon. After further movement on the sliding wall 4 to the end position, the locking pawl 11 falls under its own weight, as shown in the figure, or sprung in a known manner with a semicircular shape recess 14 on the locking pin 9. In this state the sliding wall 4 is secured in the longitudinal direction of the carriage. For complete closing, the sliding wall 4 is swung in and down by the ejection device 5. According to FIG. 3, the locking pin 9 leaves the recess 14 of the locking pawl 11a and the locking pawl 11 falls down to the stop 13. When opening, the sliding wall 4 is pushed outwards and upwards by the ejection device 5. Since the locking pawl 11 abuts the stop 13, the locking pin 9 extends along the upper edge of the locking pawl 11. In the displacement process of FIG. 4, in the initial phase, presses the guide thumb 12 of the drive lever 10 downward with the locking pin 9 and the sliding wall can pass freely. When the locking pin 9 has passed along the guide thumb 12, the drive lever 10 falls under its own weight or springed up to the stop 13 'back to the locking pawl 11a and the readiness for locking is again restored. It is within the scope of the present invention that the lead-in lever 10 is rigidly attached to the locking pawl 11 and the locking pawl 11 is held in the locking position by known energy-storing elements 15, for example springs. Further embodiments of the arrangement of the locking pin 9 and the start lever 10 and the locking pawl 11 are provided. Here, the locking pin 9 is fixed rigidly to the underside of the car and the starting lever 10 and the pawl 11 are pivotable on the movement mechanism 8 via the pivot 17. a pin 9, which is mounted on a lever 19, pivotally mounted via a swivel joint 18 to the underside of the wagon and a locking pawl 11, equipped with a guide thumb 12 and a recess 14, pivotally mounted via a swivel joint 17 to a movement mechanism 8. the sliding wall 4 is preferably securely locked in the CLOSED position. When the sliding wall 4 is opened, this locking device is released automatically and uncomplicated, so that no additional operator effort is required.
