[0042] Embodiment one, refer to Figure 1 and Figure 4 The first embodiment of the present application is a kind of automatic door opening spreader for container.
[0043] In this embodiment, the door opening spreader includes a lock sleeve 3, a lock pin 4, a rack 5 and an unlocking rope 6; wherein the rack 5 is movable relative to the cabin carrying goods, the rack 5 is moved by means of the existing technology crane or crane, the lock sleeve 3 can be a separate component with locking hole, or according to the structure of the box 1, a part of the box 1 can be directly selected, and the locking hole is formed on the selected box 1.
[0044] When working, the container is hung on the rack 5, then the rack 5 is driven to move above the ship cabin, the rack 5 is kept stationary, then external force is applied to drive the container to rotate, so that the container rotates relative to the rack 5, at this time the door 2 on the box body 1 rotates towards the direction close to the ship cabin; with the rotation of the box body 1, the relative movement away between the locking pin 4 on the door 2 and the rack 5 occurs; in the process of the rotation of the box body 1, the locking pin 4 is pulled out of the locking sleeve 3 by the pulling of the unlocking rope 6, so that the locking and fixing between the door 2 and the box body 1 is released, at this time the door 2 on the box body 1 rotates under the gravity of the goods in the box body 1 and the gravity of the door 2 itself, the door 2 is opened, the goods fall from the door 2 and drop into the ship cabin for loading, the automatic unlocking of the locking pin 4 is completed by the unlocking rope 6, the door 2 is opened, and no personnel is involved in the process, so that the risk of personnel injury is avoided; at the same time, since the workers are not needed to open the door 2 on the spot, the workers are also avoided from being placed in the ship cabin with flying dust, so that the physical and mental health of the workers is protected.
[0045] Embodiment two, refer to Figures 1-2 and Figure 4 , the second embodiment of the utility model, on the basis of embodiment one, the structure of the door opening lifting device is further improved, the lifting shaft 7, the lifting rope 8, the tilting shaft 9 and the tilting rope 10 are added, the number of the lifting shaft 7, the lifting rope 8, the tilting shaft 9 and the tilting rope 10 is preferably two; the hinged seat 11 and the rope head lock 13 are also added; wherein the number of the hinged seat 11 and the rope head lock 13 is preferably four, two rope head locks 13 correspond to two tilting ropes 10, and the other two rope head locks 13 correspond to two lifting ropes 8.
[0046] When in use, the power provided by the external power driver is used to drive the lifting shaft 7 and the tilting shaft 9 to rotate; the external power driver is preferably an electric motor driven by electricity; when it is needed to adjust the height position of the box body 1, the lifting shaft 7 and the tilting shaft 9 are simultaneously driven to rotate, the lifting shaft 7 releases or winds the lifting rope 8 when rotating, and the tilting shaft 9 releases or winds the lifting rope 8 when rotating, the lifting rope 8 and the tilting rope 10 are simultaneously wound or released; then the height position of the box body 1 is adjusted; when it is needed to tilt the box body 1 to dump the goods, the power provided by the external power driver is used to realize one of the following three operations, the first one is to wind the lifting rope 8, the second one is to release the tilting rope 10, and the third one is to wind the lifting rope 8 and release the tilting rope 10 at the same time; as long as any one of the above three operation states is realized, at this time the side of the box body 1 close to the door 2 starts to rotate towards the direction close to the bottom of the ship cabin, the locking pin 4 is pulled out of the locking hole by the unlocking rope 6, the door 2 rotates on the box body 1, the door 2 is opened, the goods fall from the door 2 and drop into the ship cabin, and the loading operation of the goods is completed.
[0047] During the operation, the four articulated seats 11 are distributed as shown in Figure 1 The articulated seats 11 and the articulated rods 12 rotatably arranged on the articulated seats 11 ensure that the lifting ropes 8 and the tilting ropes 10 are in straight state during the lifting and tilting of the box body 1, and no dead bending or bending position occurs, thereby prolonging the service life of the lifting ropes 8 and the tilting ropes 10.
[0048] Embodiment three, referring to Figures 1-4 As the third embodiment of the utility model, on the basis of the first embodiment, the embodiment further increases the guide 14 and the limiting pin 16. During use, the unlocking rope 6 is passed through the rope passing hole of the guide 14, and the arc surface 15 on the rope passing hole is used to reduce the friction between the unlocking rope 6 and the rope passing hole. Meanwhile, the guide 14 can be used to limit the action range of the unlocking rope 6, so as to avoid the extrusion and abrasion between the unlocking rope 6 and the box door 2 or the box body 1.
[0049] In addition to the guide 14 shown in Figure 1 and Figure 3 , a pulley in the prior art can be rotatably arranged on the guide 14, and the pulley is used to replace the rope passing hole, thereby guiding the unlocking rope 6 and reducing the friction on the unlocking rope 6.
[0050] When the box body 1 does not need to work, the limiting pin 16 can be removed, and then the guide 14 on the side of the box door 2 is retracted to the top cover of the box body 1 by rotating the guide 14, thereby reducing the space occupied by the exposed guide 14. Meanwhile, the limiting pin 16 can be used to limit the position range of the guide 14, thereby ensuring the smooth operation of the door opening lifting device.
[0051] Embodiment four, referring to Figure 1 and Figure 4For the fourth embodiment of the utility model, on the basis of example one, the structure of the door opening hanger is further improved, the guide pin seat 17, the limiting ring 18 and the spring 19 are added, the box door 2 needs to be closed before loading the box body 1; at this time, external force is applied, the locking pin 4 is first slid upward along the guide pin hole, the locking pin 4 drives the limiting ring 18 to compress the spring 19, the box door 2 is rotated until the locking pin 4 is aligned with the locking hole on the lock sleeve 3, at this time, the force applied to the locking pin 4 is released, the spring 19 releases the accumulated elastic force, with the help of the force provided by the spring 19, the locking pin 4 slides downward along the guide pin hole until the locking pin 4 passes through the locking hole, when the limiting ring 18 is in extrusion contact with the lock sleeve 3, the sliding of the locking pin 4 is stopped, at this time, the spring 19 is located between the limiting ring 18 and the guide pin seat 17, the spring 19 is in a compressed state, with the help of the force provided by the spring 19, it is ensured that the locking pin 4 is firmly inserted into the locking hole, preventing the locking pin 4 from separating from the lock sleeve 3, and the problem of the box door 2 opening too early.
[0052] When the goods are inclined, external force is applied to drive the container to rotate, at this time, the position of the lock sleeve 3 moves away from the rack 5, the unlocking rope 6 drives the locking pin 4 to move away from the lock sleeve 3, until the locking pin 4 separates from the locking hole, the box door 2 is opened, at this time, the spring 19 is in a compressed state, with the continuous rotation of the box body 1, the unlocking rope 6 continues to slide with the locking pin 4, the limiting ring 18 gradually approaches the guide pin seat 17, the spring 19 continues to be compressed, with the help of the unlocking rope 6, the separation operation of the box door 2 and the box body 1 can be accelerated, with the help of the spring 19, the unlocking rope 6 can keep in a taut state, and the problem of the unlocking rope 6 breaking can also be avoided.
[0053] It should be noted that the above examples are only used to illustrate the technical solutions of the utility model and not to limit, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, which should be covered in the scope of the claims of the utility model.
