Abstract
A container locking device for locking a container having a corner fitting to be transported on a loading surface of a vehicle, having a locking housing, a locking bolt and a drive. The locking bolt has a shaft and a locking head which, in the unlocked state, can be inserted through an opening of the corner fitting of the container and rotated 90° into the locked state in which it secures the container via protrusions which engage behind the opening of the corner fitting. The locking bolt is driven to be both axially displaceable and rotatable about its axis. The invention further relates to a container locking method that can be carried out using the above-mentioned device.
Claims5
A container locking device (5) on a vehicle, adjustable between a locked state for locking a container with a corner fitting (7) to be transported on a loading surface (8) of the vehicle and an unlocked state in which a container can be unloaded or loaded, having a locking housing (1), a locking bolt (2) and a drive (3), wherein
- the locking bolt (2) has a shaft (20) and a locking head (21), which in an unlocked state of the locking bolt (2) can be inserted via an opening in the corner fitting (7) of the container and in a locked state of the locking bolt (2) secures the container via projections engaging behind the opening in the corner fitting (7),
- the locking bolt (2) is mounted with the shaft (20) of the locking bolt (2) in the locking housing (1) so that the locking bolt (2) can be moved both axially and rotatably about an axis of the locking bolt (2),
- the locking bolt (2) is provided on the shaft (20) with a recess (23) that is inclined tangential to a circumference of the recess (23),
- a wedge slide (4) is mounted in the locking housing (1) laterally, i.e. perpendicular to the axis of the locking bolt (2), so that the wedge slide (4) can be moved back and forth and can be driven by the drive (3),
- the wedge slide (4) has an inclined support (41) which engages with the recess (23) of the locking bolt (2) during the lateral movement of the wedge slide (4) and gives the locking bolt (2) an axial movement,
- the locking bolt (2) has a contact edge (24) on the shaft (20), which cooperates with a pushing protrusion (42) of the wedge slide (4) to give the locking bolt (2) a 90° rotational movement during the lateral movement of the wedge slide (4),
- the locking device (5) is arranged on the locking housing (1), which has a spring-loaded lock (51) which is designed to intrude in the lateral movement path of the wedge slide (4),
- the drive (3) has a double-acting pneumatic cylinder (30) with a laterally movable piston rod (31), the piston rod (31) being operatively connected to the wedge slide (4) in such a way that during a first part of the stroke movement of the drive (3) an idle stroke takes place and in a second part of the stroke movement the lateral movement of the wedge slide (4) takes place, and
- the locking device (5) has a release mechanism for the lock (51), which releases the lock (51) during the idle stroke.
A method for locking a container with a corner fitting (7) to be transported on a loading surface (8) of the vehicle, the method comprising
- seating the container with the corner fitting (7) onto the loading surface (8) of the vehicle, and
- releasably locking the container to the vehicle using a container locking device (5) adjustable between a locked state for locking the container with the corner fitting (7) to be transported on a loading surface (8) of the vehicle and an unlocked state in which a container can be unloaded or loaded, the container locking device (5) comprising a locking housing (1), a locking bolt (2) and a drive (3),
- wherein
- the locking bolt (2) has a shaft (20) and a locking head (21), which in an unlocked state of the locking bolt (2) can be inserted via an opening in the corner fitting (7) of the container and, in a locked state of the locking bolt (2), secures the container via projections that engage behind the opening of the corner fitting (7),
- the locking bolt (2) with the shaft (20) is both axially displaced in the locking housing (1) and rotatable about an axis of the locking bolt (2),
- a wedge slide (4) in the locking housing (1) can be moved back and forth laterally by the drive (3), i.e. perpendicular to the axis of the locking bolt (2), and
- during the lateral movement of the wedge slide (4) by the drive (3) of the wedge slide (4), the locking bolt (2) first rotates axially by 90° when adjusting from the unlocked state to the locked state and then axially downwards to be lowered towards the loading surface (8),
- wherein when the locked state is reached, a spring-loaded lock (51) intrudes in the lateral movement path of the wedge slide (4) and prevents the wedge slide (4) from being reset, and wherein during a first part of the stroke movement of the drive (3) an idle stroke is carried out and during a second part of the stroke movement the wedge slide (4) is moved, whereby when unlocking a container from a locked state to an unlocked state of the container, the lock (51) is released during the first part of the stroke movement in the idle stroke and then during the second part of the stroke movement the wedge slide (4) is moved back whereby the locking bolt (2) is initially raised and then turned back to the unlocked state of the locking bolt (2).
