[0002] Container conveying devices, specifically container straddle carriers, are characterized by flexibility, high efficiency, and good stability. They are increasingly used in the loading and unloading of containers and large materials. As the transportation industry places higher and higher demands on environmental protection and safety, many large and bulk materials are required to be loaded into containers for transportation.

[0003] Traditional container straddle carriers are mainly used to transfer containers at ports, logistics centers, etc. They are usually equipped with a powerful power system, lifting mechanism and walking mechanism, which can easily lift, transport and stack containers;

[0004] Traditional container straddle carriers are used to transfer containers, and the containers are loaded with goods that do not need to be unloaded and stacked, such as goods loaded in cartons. Due to the internal space of the container, the manpower required to enter the container to load and unload the goods is limited, and a large amount of goods cannot be handled at the same time, resulting in low overall operation efficiency. For this reason, we propose a container conveying device with self-unloading function. Summary of the invention

[0032] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a container conveying device with a self-unloading function includes a container conveying frame 11, on which a container clamping member 12 and a container clamping member 2 13 are arranged, which are used to clamp the container and move it to a preset position with the conveying frame, and an auxiliary container unloading mechanism 2 is arranged on the side of the container clamping member 12 close to the container loading and unloading port;

[0034] The auxiliary unloading mechanism 2 includes a telescopic arm 27 and an insertion head 28. The telescopic arm 27 is assembled from a plurality of telescopic inner and outer columns. The top end of the smallest arm is fixedly connected to the insertion head 28. The insertion head 28 is provided with a power assist mechanism 3 inside.

[0035] The boost mechanism 3 includes a box-pushing arm 31, which is rotatably disposed in the insertion head 28, and a slot insertion arm 33 is fixedly disposed at the top end of the box-pushing arm 31;

[0036] After the container conveying rack 11 moves to the specified position, the container is adjusted by the box clamping part 12 and the box clamping part 2 13 so that one end of the loading and unloading port is lower than the other end to form an inclination. Subsequently, the telescopic arm 27 drives the insertion head 28 to be inserted along the groove at the top of the inner wall of the container. When the insertion head 28 and the power-assisting mechanism 3 it carries enter the interior of the container and reach the gap between the two cartons, the box pushing arm 31 rotates to insert the gap arm 33 into the gap between the cartons, and applies a thrust to the topmost carton in the container by rotating counterclockwise, causing it to slide out along the inclined surface of the container.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the box clamping part 12 is fixedly connected to the container conveying frame 11, and a lifting hydraulic machine 17 is fixedly arranged on the box clamping part 12. The telescopic shaft of the lifting hydraulic machine 17 passes through one end of the box clamping part 12 and a box clamping frame 14 is fixedly arranged. The box clamping part 2 13 is the same as the box clamping part 12. The box clamping part 2 13 and the box clamping part 12 are respectively fixed at the two ends of the container conveying frame 11, and the box clamping frame 14 is telescopically connected to the box clamping part 12 through the lifting hydraulic machine 17.

[0038] A box clamping hydraulic press 15 is fixedly installed on the outer wall of the box clamping frame 14. The telescopic axis of the box clamping hydraulic press 15 passes through one end of the box clamping frame 14 and a box clamping plate 16 is fixedly installed. A box clamping pad 18 is provided on the inner wall of the box clamping plate 16. The box clamping plate 16 is telescopic with the box clamping frame 14 through the box clamping hydraulic press 15.

[0039] After the container conveying rack 11 moves onto the container, the lifting hydraulic machine 17 pushes the clamping rack 14 down, so that the side arm of the clamping rack 14 drops to the middle and upper part of the container side wall, and then the clamping plate 16 is driven by the clamping hydraulic machine 15 to clamp the container side wall, and the outer surface of the container is protected by the clamping pad 18. After the clamping plates 16 on both sides of the container clamp the container, the lifting hydraulic machine 17 drives the clamping rack 14 and the container to move upward and off the ground;

[0040] The work of the second box clamping part 13 is exactly the same as that of the first box clamping part 12. The box clamping plate 16 on the second box clamping part 13 is a rotating connection method and completes the work at the same time, so that the container is completely off the ground, and then moved to the predetermined position where unloading is required through the container conveying rack 11. At this time, the box clamping hydraulic press 15 on the box clamping rack 14 gradually reduces the clamping force on the container, while the clamping force of the second box clamping part 13 remains unchanged. Under the gravity of the container, the end close to the box clamping part 12 naturally droops, causing the container to tilt. After the container door is opened, the goods can be dumped out by themselves.

[0041] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the auxiliary container unloading mechanism 2 also includes a connecting frame 21, one end of which is provided with a locking groove 204, an inner part of which is movably provided with a locking head 205, a container following plate 22 is fixedly provided below the locking head 205, the size of the locking head 205 matches the size of the locking groove 204, the connecting frame 21 and the container following plate 22 are perpendicular to each other, and the container following plate 22 is parallel to the container loading and unloading port.

[0042] A force box 24 is fixedly provided on the upper wall of the connecting frame 21, and a plurality of winding drums 201 are provided inside the force box 24. A pull-back belt 202 is fixedly provided on the winding drum 201, and the end of the pull-back belt 202 away from the winding drum 201 is fixedly connected to the positioning head 205. A coil spring 203 is provided inside the winding drum 201, and a support column 29 fixedly connected to the force box 24 is passed through the interior of the coil spring 203.

[0043] A plurality of arm retracting boxes 23 are fixedly provided on one side of the box plate 22, and an air inlet end of the arm retracting box 23 is connected to a ventilation pipe 25. The plurality of arm retracting boxes 23 are interconnected through the ventilation pipe 25, and a high-pressure air pump 26 is installed at one end of the ventilation pipe 25 away from the arm retracting box 23. The telescopic arm 27 is slidably provided inside the arm retracting box 23, and a first air supply pipe 32 is provided in the ventilation pipe 25.

[0044] A limit plate 271 is fixedly provided at one end of the telescopic arm 27 away from the insertion head 28, and a tension belt 272 is fixedly provided on the side of the limit plate 271 away from the telescopic arm 27, and one end of the tension belt 272 away from the limit plate 271 is fixedly connected to the inner wall of the arm retracting box 23, and the gas in the ventilation pipe 25 flows out in two parts, one part enters the arm retracting box 23, and the other part flows into the first gas supply pipe 32.

[0045] When the container is clamped by the clamping member 12, the door frame of the container is just stuck between the connecting frame 21 and the container plate 22, and the door frame of the container is blocked to a certain extent by a plurality of insertion heads 28. If this step is not completed, the staff can manually adjust it so that the insertion head 28 can be just inserted into the groove of the inner wall of the container;

[0046] When the container is tilted, the box plate 22 moves with the container, and then the high-pressure air pump 26 is used to ventilate the vent pipe 25, so that the air pressure in the arm retracting box 23 gradually increases. As the air pressure in the arm retracting box 23 gradually increases, the telescopic arm 27 is pushed to extend, so that the insertion head 28 is gradually extended along the groove of the inner wall of the container. At the same time, when the insertion head 28 and the power-assisting mechanism 3 carried by it enter the interior of the container and reach the gap between the two cartons, the box-pushing arm 31 rotates, so that the slot-inserting arm 33 is inserted into the gap of the cartons, and a thrust is applied to the top carton in the container by counterclockwise rotation, so that it slides out along the inclined surface of the container;

[0047] Finally, when the unloading is completed, the high-pressure air pump 26 stops supplying air. At this time, the elastic force of the tension belt 272 causes the extended telescopic arm 27 to gradually retract and pull back the insertion head 28. The staff separates the arm box 23 and the container tightly, and drives the reel 201 to rotate through the elasticity of the coil spring 203, and rewinds the pull-back belt 202, thereby pulling the box plate 22 to reset, so that the positioning head 205 is re-stuck in the positioning slot 204, so as to facilitate the next work.

[0048] like Figure 6 , Figure 8 and Fig. 9 As shown, the power assist mechanism 3 also includes a rotating drum 34, and two groups of pushing box arms 31 are distributed on the outer wall of the rotating drum 34. The two groups of pushing box arms 31 are parallel to each other. A plurality of air receiving scoops 36 are fixedly arranged on the rotating drum 34 between the two groups of pushing box arms 31. A fixing column 35 is passed through the interior of the rotating drum 34, and the fixing column 35 is fixedly connected to the insertion head 28, and the fixing column 35 is rotatably connected to the rotating drum 34.

[0049] A fixing plate 38 is fixedly provided on the fixing column 35 , and a jet port 37 is fixedly provided at the center position of one end of the fixing plate 38 . The jet port 37 is aligned with the air receiving spoon 36 , and the jet port 37 is connected to the first air pipe 32 , and the first air pipe 32 is connected to the second air pipe 42 .

[0050] While the telescopic arm 27 pushes the insertion head 28 toward the interior of the container, a portion of the gas in the ventilation pipe 25 is ejected from the jet port 37 at high pressure through the first air supply pipe 32. The ejected gas from the jet port 37 impacts the air receiving scoop 36, which drives the rotating drum 34 to rotate, thereby driving the two sets of box pushing arms 31 to rotate through the rotating drum 34. The rotation of the two sets of box pushing arms 31 can apply a certain thrust to the cartons in contact with them, thereby increasing the power for the cartons to naturally slide out of the container. When the slotting arm 33 contacts the slot of the carton, it is inserted into the slot of the carton and applies thrust to the top carton in the container by rotating counterclockwise, causing it to slide out along the inclined surface of the container.

[0051] like Fig.10As shown, an air box 43 is provided at one end of the second air supply pipe 42 away from the air jet 37, and the air box 43 is fixedly connected to the fixed plate 38, the air outlet end of the air box 43 is fixedly connected to the air vent 41, a resistance plate 45 is fixedly provided inside the air vent 41, an air-blocking film 46 is fixedly provided on the lower wall of the resistance plate 45, a spring 47 is fixedly provided inside the air-blocking film 46, an air-blocking pull wire 48 is fixedly provided at the center position of the air-blocking film 46, a force-bearing plate 44 is fixedly provided at one end of the air-blocking pull wire 48 away from the air-blocking film 46, and the force-bearing plate 44 is rotatably connected to the air vent 41.

[0052] When the slotting arm 33 withdraws the carton, the carton does not slide out, and the box-pushing arm 31 stops rotating. At this time, the box-pushing arm 31 cannot push the force-bearing plate 44. The air box 43 is always inflated through the second air delivery pipe 42, and the air box 43 is sealed through the air-blocking film 46. As the air pressure gradually increases, when the air pressure exceeds a predetermined value, the air-blocking film 46 instantly rotates clockwise to release air. The instantaneous release of high pressure will produce an explosion sound, thereby simulating the explosion impact under the action of high-pressure gas, which instantly acts on the carton and promotes the carton to slide out;

[0053] If the box-pushing arm 31 rotates smoothly, the box-pushing arm 31 will contact the force-bearing plate 44, and pull the air-blocking film 46 to swing through the force-bearing plate 44, and continue to deflate. After each simulated explosion impact, the air-blocking film 46 is reset by pulling the deflation pull line 48.

[0054] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
