Description

Technical Field

[0001] This invention relates to the field of container technology, specifically to a container unloading end door and a container having the same. Background Technology

[0002] As is well known, container unloading end doors are a special type of door specifically designed for the end of bulk material containers, adapted for mechanized and rapid unloading and capable of being opened to a large degree. Due to the structural characteristics of this special door, it requires a specially structured container for use.

[0003] A search revealed that Chinese patent application number CN201410500075.6 discloses a container unloading end door and a container having the same. The general description is as follows: The container unloading end door is detachably mounted inside the container end door. The unloading end door includes at least one crossbeam and an openable unloading device. At least one crossbeam is connected to the container. Above the unloading device, at least one detachable crossbar is provided, connected to a baffle. In use, this forms a container with an unloading end door, and when not in use, the unloading end door can be removed, turning the container into a regular container.

[0004] Although the aforementioned existing technical solutions propose corresponding container unloading end doors and containers with them, the overall technical solutions only add detachable container unloading end doors.

Each left shaft cylinder 3 and each right shaft cylinder 4 is slidably connected to two insertion shafts 23, which respectively match the multiple insertion holes 22. Multiple left end doors... Each of the 7 and multiple right-side doors 8 is connected to a sector-shaped cylinder 24, and each sector-shaped cylinder 24 has a dovetail groove. Each of the multiple left-side doors 7 and multiple right-side doors 8 is fixedly connected to a dovetail strip, which is slidably disposed within the dovetail groove. Each of the multiple sector-shaped cylinders 24 is slidably connected to an upper telescopic shaft 25 and a lower telescopic shaft 26. The multiple upper telescopic shafts 25 are respectively inserted into multiple left-side cylinders 3 and multiple right-side cylinders 4, and the multiple lower telescopic shafts 26 are respectively inserted into multiple left-side cylinders 3 and multiple right-side cylinders 4. An elastic spring 27 is provided between the corresponding upper telescopic shafts 25 and lower telescopic shafts 26, and a protective sleeve 28 is fixedly connected to the outside of the elastic spring 27. Multiple left-side plates 5 (excluding the last left-side plate 5) and multiple right-side plates 6 (excluding the last right-side plate 6) are also provided. The rear ends of each door are fixedly connected to limit plates 9. Through the design of the container unloading end door assembly, it can cooperate with the container to form multiple sections. On the one hand, it can separate and store the bulk materials stored in the container. On the other hand, it can classify and store various bulk materials. The left end door 7 and the right end door 8 at the front are both equipped with limit components. The two limit components match each other. The bottom end of the top mounting frame 1 is provided with two top limit ports 10 that match the two limit components respectively. The top end of the bottom mounting frame 2 is provided with two bottom limit ports 11 that match the two limit components respectively. Both limit components include vertical mounting cylinders 12. The two vertical mounting cylinders 12 are fixedly connected to the left end door 7 and the right end door 8 at the front, respectively. The top lifting mechanism is slidably connected inside the two vertical mounting cylinders 12. Pin 13 and bottom lifting pin 14, the two top lifting pins 13 and the two bottom lifting pins 14 are respectively provided with bidirectional transmission components. The two top lifting pins 13 are respectively matched with the two top limit ports 10, and the two bottom lifting pins 14 are respectively matched with the two bottom limit ports 11. The bidirectional transmission component includes a transmission frame 15, which is rotatably connected in the vertical mounting cylinder 12. The top lifting pins 13 and the bottom lifting pins 14 are respectively fixedly connected with transmission rods 16. The transmission frame 15 has an outer strip-shaped opening 17 and an inner strip-shaped opening 18. The two transmission rods 16 are respectively inserted into the inner strip-shaped opening 18 and the outer strip-shaped opening 17. Through the design of the limiting component, the left end door 7 and the right end door 8 at the front end can be closed, locked and limited, realizing the front end closure of the container, making the operation more convenient.

[0023] It should be further explained that the transmission frame 15 is fixedly connected to the forward extension shaft 19, and each of the two forward extension shafts 19 is fixedly connected to an auxiliary operating ring 20. Each of the two auxiliary operating rings 20 is provided with an alignment locking hole 21. By aligning the two alignment locking holes 21 left and right and inserting an external lock, the relative position between the two auxiliary operating rings 20 can be locked. The front end of the bottom mounting frame 2 has two front bevels 29, which are respectively connected to two bottom limit ports 11.

The limit locking sleeve 34 matches the fixed locking sleeve 33.

[0024] A container adapted to a container unloading end door includes a container body and a container unloading end door assembly. The container body includes an outer frame 35, a top mounting frame 1 and a bottom mounting frame 2, both fixedly connected within the outer frame 35. A support panel 36, a rear end plate 37 and a top panel 38 are fixedly connected within the outer frame 35. The top panel 38 has multiple material distribution openings, and a top cover plate 39 is rotatably installed at each of the multiple material distribution openings. A synchronizing rod 40 is provided on the top panel 38, and multiple hinge ears 41 are fixedly connected to the synchronizing rod 40. The multiple hinge ears 41 are respectively hinged to the multiple top cover plates 39. A locking frame 42 is provided on the outer frame 35, and a locking ring 43 matching the locking frame 42 is provided on the synchronizing rod 40. By equipping the container with the container unloading end door assembly, a complete storage container can be formed in conjunction with the container unloading end door assembly to facilitate the creation of storage space for bulk materials.

[0025] In summary, the working principle of the container unloading end door and the container with it is as follows: During use, the operator closes multiple left end doors 7 and multiple right end doors 8 one by one from back to front according to the loading requirements. Except for the two frontmost sector cylinders 24, the remaining sector cylinders 24 are all fixedly installed with limit panels that match the limit strips 9. After the front and rear adjacent limit strips 9 contact each other with the limit panels, the front left side plate 5 will form a rotation limit on the rear adjacent left end door 7, and the front right side plate 6 will also form a rotation limit on the rear adjacent right end door 8. After all the left end doors 7 and right end doors 8 are closed in sequence, the internal partitioning of the container can be completed. Rotating the auxiliary operating ring 20 can drive the forward rotating shaft 19 to rotate, thereby driving the transmission frame 15 to move, relying on the outer strip opening 17 and the inner strip opening 18. The linkage with the corresponding internal transmission rods 16 drives the top lifting pin 13 and the bottom lifting pin 14 to move synchronously towards each other, respectively engaging the top limit port 10 and the bottom limit port 11, thereby achieving synchronous locking of the left end door 7 and the right end door 8 at the front end. Aligning the locking holes 21 of the two auxiliary operating rings 20 and inserting external locks, the relative locking between the two auxiliary operating rings 20 can be completed. Then, by operating the top synchronous rod 40, all the top cover plates 39 are opened synchronously through the hinge ear 41, fully exposing the material feeding ports, so that materials can be fed into each independent zone to realize the loading operation. Since each material feeding port corresponds to an isolation zone, and the material feeding port occupies a large proportion of the plane above the zone, the empty space between the bulk material and the top panel 38 is smaller after loading, and the overall loading rate is effectively improved.

[0026] After loading is completed, pull the synchronizing rod 40 to reset it, close all top cover plates 39 to achieve synchronous sealing of multiple material feeding ports, and then lock all top cover plates 39 synchronously through the cooperation of locking ring 43 and locking frame 42 to prevent dust leakage during transportation. When unloading, first remove the lock in the aligning lock hole 21, rotate the auxiliary operating ring 20 in the opposite direction, and drive the top lifting pin 13 and bottom lifting pin 14 to retract synchronously through the transmission structure, releasing the locking state of the front left end door 7 and right end door 8. Then slightly open the front left end door 7 and right end door 8, and the material automatically slides down from the gap between the two end doors. Due to the notches on the right shaft cylinder 3 and the right shaft cylinder 4, the rotation range of the sector cylinder 24 is limited. Initially, when the left end door 7 and the right end door 8 open, the internal material is relatively abundant, which will obstruct the left side plate 5 and the right side plate 6. Therefore, the left side plate 5 and the right side plate 6 will remain in their original state. As the internal material decreases and the obstruction weakens, the relative opening range of the left end door 7 and the right end door 8 will be increased, causing the corresponding left side plate 5 and right side plate 6 to move synchronously. While the left side plate 5 and the right side plate 6 rotate and open relative to each other, they will assist in pushing the internal bulk material, accelerating the discharge speed of the bulk material and improving the unloading effect. By opening the left end doors 7 and right end doors 8 sequentially from front to back, materials in each isolation zone can be unloaded in batches. If different bulk materials are stored in the front and rear zones, before the left side plate 5 and right side plate 6 are rotated to open, the rear set of left end doors 7 and right end doors 8 can be locked and limited before further rotating to open the front set of left end doors 7 and right end doors 8 to prevent accidental opening of the rear set of left end doors 7 and right end doors 8 and resulting material mixing. After the material in the previous zone is completely unloaded, the lock can be released and the unloading of the next zone can continue. After all unloading is completed, the equipment can be reset and put back into transport use. During maintenance and repair, [the equipment should be kept in a safe position]. The elastic force of the spring 27 causes the upper telescopic shaft 25 and the lower telescopic shaft 26 to slide towards each other, allowing them to be pulled out from the left shaft cylinder 3 or the right shaft cylinder 4. After that, the supporting and limiting effect of the two insert shafts 23 inside the left shaft cylinder 3 or the right shaft cylinder 4 disappears, and the left shaft cylinder 3 and the right shaft cylinder 4 can be removed from between the top mounting frame 1 and the bottom mounting frame 2, which facilitates partial maintenance or parts replacement of the container unloading end door assembly. If it is necessary to cancel the internal isolation partition and use the container as a whole storage space, simply pull the dovetail strip out of the dovetail groove and reassemble the sector cylinder 24 relative to the left shaft cylinder 3 and the right shaft cylinder 4.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
