Definitions

  • the invention relates to a device for fixing a container on the bed of a vehicle according to the features of the preamble of patent claim 1.
  • the device has a pin with a mushroom-like head, which is displaceable about its longitudinal axis.
  • the pin is also rotatable.
  • an ISO container has a container casting in the form of a corner fitting.
  • the container casting has an opening in the form of a slot. After insertion from below into the slot of the container casting and the subsequent rotation of the pin engages behind the edges of the slot with its mushroom-like head and so sets the container casting and thus the container to the loading area.
  • the pin is rotatable and liftable by means of a lifting drive along its longitudinal axis.
  • the pin is now secured in a securing position by means of a locking means against rotation and against axial displacement.
  • the pin has a through hole extending transversely to its longitudinal axis.
  • the through hole is formed with a ramp on its side facing away from the head.
  • a locking element or locking means is designed as a locking wedge, which can be inserted into the through hole.
  • the locking wedge is actuated by means of a hydraulic cylinder. It is provided as a rotary drive a rotary cylinder.
  • the pin is pressed by the force of a spring in its extended position. This spring serves as a lifting drive.
  • twist lock is known from US Pat. No. 5,927,916, wherein the twist lock is automated and thus operable remotely.
  • a piston-cylinder arrangement is arranged below the loading surface as the lifting drive, which moves the pin along its longitudinal axis, i. essentially vertically displaced.
  • a motor is provided to turn the pin. This serves as a rotary drive.
  • the invention has the object to improve the device for fixing the container.
  • the lifting drive is designed in such a way that a head of the pin is displaceable through the oblong hole into a first end position, wherein in the first end position the head of the pin is spaced with an axial clearance relative to the edge of the slot, the pin then being in a second end position is retractable, in which the head of the pin rests against the edge of the slot.
  • the method is characterized in that a head of the pin is displaced through the slot to a first end position, wherein in the first end position, the head of the pin with an axial clearance relative to the edge of the slot is spaced, the pin then into a second end position is retracted, in which the head of the pin rests against the edge of the slot.
  • the pin is thereby extended further in the longitudinal direction than it would be necessary in principle, namely so that between the upper edges of the slot and the bottom of the head of the pin axial play remains. This ensures that the pin can be safely rotated without abutting the inner wall of the slot. When turning or after the rotation of the pin is withdrawn and thus lies with his head on the edges of the slot.
  • This game i. the axial distance of the bottom of the head to the top of the bottom of the container locking is preferably more than 0.5 times the axial thickness of the head.
  • this axial play can substantially correspond to the axial thickness of the head.
  • the lifting drive has a cylinder and a piston, wherein the pin is displaceable by displacing the piston.
  • the lifting drive is preferably hydraulically actuated.
  • the lifting drive can be actuated pneumatically or by a motor, for example by means of a toothed rack or a worm drive.
  • the lifting drive is designed in particular as a pneumatically or hydraulically operable cylinder.
  • a corresponding piston is slidably disposed, wherein the piston interacts directly or indirectly with the pin.
  • the locking element is displaceable by a cylinder piston assembly.
  • the cylinder arrangement is preferably hydraulically actuated.
  • the locking element can be pneumatically or motor-driven, for example by means of a rack.
  • the locking element is inserted into a passage opening in the pin.
  • the passage opening may be formed as a bore and extends transversely, preferably perpendicular to the longitudinal axis of the shaft of the pin.
  • the pin preferably has a control cam on the circumference, wherein in the control cam engages a rotatable control cam, wherein the pin is rotatable about its longitudinal axis by rotation of the control cam.
  • the axis of rotation of the control cam is arranged in particular at right angles to the longitudinal axis of the pin.
  • the control cam can alternatively also by a rotary drive in particular a motor to be driven.
  • the motor can work hydraulically, pneumatically or electrically.
  • An incline of the control cam and / or the shape of the control cam may vary such that the rotational speed of the journal is not proportional to the rotational speed of the control cam. This has the advantage that the pin, for example, reaches a greater acceleration when it has reached the fully extended position and the rotation can be completed before the head abuts the top of the edges of the slot.
  • the rotary drive may be formed by a ring gear on the pin or on a non-rotatably connected to the pin member and a motor drive of the ring gear.
  • the device is remotely controllable from the cab of the vehicle. As a result, the operator does not have to leave the cabin to secure the container by means of the devices.
  • FIG. 1 shows a schematic sectional view of a device for securing a container on a loading area of a vehicle with a container casting, wherein a pin is arranged in a lower position
  • FIG. 2 is a schematic, sectional view of the device of the container locking, wherein the pin is arranged in an upper, engaging in the container casting, first end position
  • Fig. 3 shows a schematic, sectioned view of the device and the container casting, wherein the pin is now arranged in a voltage applied to the bottom of Containercastings, second end position, but a locking element is not yet arranged in a blocking position
  • Fig. 4 is a schematic, sectional view of the device of the container locking, wherein the pin is arranged in the position of Fig. 3 and now the locking element is arranged in the blocking position.
  • FIGS. 1 to 4 a device 1 for fixing a container on the loading area of a vehicle, not shown, is clearly visible. These devices 1 are also referred to as a twist lock. From the container, only a corner fitting, namely a so-called container casting 2 is shown.
  • the container casting 2 is formed by a housing 3, wherein the housing 3 has a slot 5 at its bottom 4.
  • the device 1 now has a pin 6, wherein the pin 6 has a head 7.
  • the head 7 is not formed rotationally symmetrical, but, for example, rectangular.
  • the head 7 is oriented such that the head 7 can be pushed by the movement along the unspecified longitudinal axis of the pin 6 through the slot 5.
  • the head 7 can be brought to bear against the unspecified edges of the slot 5 (see Fig. 3 and 4), so that the container casting 2 on a base plate 8 of the device 1 are fixed to the plant can.
  • the base plate 8 may form part of the loading area of the vehicle.
  • the pin 6 After insertion from below into the slot 5 of the container keeper 2 and the subsequent rotation of the pin 6 engages with its mushroom-shaped head 7, the edges of the slot 5 and sets the container casting 2 and thus the container to the loading area.
  • the pin 6 has a through hole 9 in the region of its unspecified shaft.
  • the through hole 9 extends transversely to the longitudinal axis of the pin 6.
  • the through hole 9 extends substantially perpendicular to the longitudinal axis of the pin. 6
  • the pin 6 is displaceable by means of a linear actuator 10 along its longitudinal axis.
  • the lifting drive 10 has a cylinder 11 and a guided piston 11 in the cylinder 12.
  • the piston 12 is guided with unspecified sealing rings on the inner wall of the cylinder 11.
  • the piston 12 carries a plunger 13 which engages in a receptacle 14 in the bottom of the pin 6.
  • the pin 6 is rotatably arranged within a sleeve 15, wherein the sleeve 15 has at least one, in particular two access openings 16.
  • the passage opening 16 is located at the height of the through hole 9 of the pin 6, wherein in the second end position of the pin 6 shown in FIGS. 3 and 4, the passage opening 16 are arranged in alignment with the through hole 9.
  • the collar 15 has a collar 17, wherein below the collar 17, a spring 18 is arranged, said spring 18, the cylinder 11 surrounds.
  • the spring 18 is supported on the one hand on the collar 17 and on the other hand on a bottom portion 19.
  • the bottom region 19 has a connection 20, which opens into the interior of the cylinder 11. Via this connection 20, a corresponding hydraulic fluid can be conducted into the cylinder 11 or removed from the cylinder 11.
  • the through hole 9 and the passage opening 16 of the sleeve 15 can be penetrated in the second end position by means of a locking element 21, whereby the pin 6 is fixed to an axially and on the other hand a rotation of the pin 6 is prevented. As a result, a securing position or a blocking position is achieved.
  • the locking element 21 is displaceable by means of a cylinder piston arrangement 22.
  • the cylinder piston assembly 22 may be hydraulically or pneumatically actuated. Alternatively, the locking member 21 may be displaced by a motor with a rack or a worm drive.
  • the automated method for actuating the device 1 is as follows. From the initial position shown in Fig. 1, the pin 6 is initially moved in the axial direction up until his head 7 has passed the slot 5. In this case, the head 7 is displaced and rotated so far upwards into a first end position that a clearance remains between the head 7 and the upper side of the oblong hole 5, as shown in FIG.
  • This clearance ie, the axial distance of the bottom of the head 7 to the top of the bottom 4 is preferably more than 0.5 times the axial thickness of the head 7. In particular, this axial play can substantially correspond to the axial thickness of the head 7.
  • the pin 6 can be retracted to the second end position (see Fig. 3).
