[0014] The present invention also provides a method for using the cargo transfer device, which specifically comprises the following steps: S1: Move the device to the location of the goods to be transferred by a transfer vehicle, so that the first support limiting mechanism and the second support limiting mechanism are respectively located on both sides of the goods to be transferred; S2: starting the driving mechanism to drive the first support and limit mechanism and the second support and limit mechanism to move in a direction close to the goods to be transferred, until the first roller and the second roller are initially pressed against the goods to be transferred; S3: Then the driving mechanism continues to drive the first support limiting mechanism and the second support limiting mechanism to move, and the first roller pushes the upper left corner of the goods to be transferred, so that the goods to be transferred flips to the right, and its lower left corner is tilted.

When the driving mechanism is started, the first supporting and limiting mechanism and the second supporting and limiting mechanism first preliminarily fix the goods to be transferred, and then the first supporting and limiting mechanism pushes the goods to be transferred to flip over and supports the bottom of the flipped side. Then the second supporting and limiting mechanism pushes the goods to be transferred to return to the center. During the return process, the bottom of the goods to be transferred is suspended in the air, and the second supporting and limiting mechanism supports the bottom of the goods to be transferred, so that the goods to be transferred can be easily moved from the plane to the transfer vehicle, and after being transferred to the designated position, the materials can be unloaded and unloaded from the transfer vehicle.

DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 11 As shown, a cargo transfer device provided by an embodiment of the present invention comprises two side plates 1, which are respectively arranged on both sides of the cargo 6 to be transferred, one side of the two side plates 1 is fixedly connected with a driving mechanism 4, and the driving mechanism 4 is installed on the transfer vehicle, the two side plates 1 are respectively provided with a first supporting and limiting mechanism 2 and a second supporting and limiting mechanism 3, the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 are both provided with a linkage mechanism 5, the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 respectively comprise a first movable plate 21, a first supporting bottom plate 22, a first pushing block 23 and a second movable plate 31, a second supporting bottom plate 32 and a second pushing block 33, the first movable plate 21 and the second movable plate 31 are respectively connected to one side of the driving mechanism 4, the first supporting bottom plate 22 and the second supporting bottom plate 32 are respectively slidably connected to the lower ends of the first movable plate 21 and the second movable plate 31, and the first pushing block 23 and the second pushing block 33 respectively abut against both sides of the upper ends of the cargo 6 to be transferred.

[0022] Furthermore, the first movable plate 21 and the second movable plate 31 are respectively slidably connected to the bottom walls of the two side plates 1, and the first support roller 24 and the second support roller 34 are rotatably installed inside the ends of the first supporting bottom plate 22 and the second supporting bottom plate 32 that are close to each other, and the first roller 231 and the second roller 331 are respectively rotatably connected inside the first push block 23 and the second push block 33, and a plurality of first guide rods 232 and a second guide rod 332 are respectively fixedly connected on one side of the first push block 23 and the second push block 33, and the first spring 233 and the second spring 333 are respectively sleeved on the first guide rod 232 and the second guide rod 332 located in the middle of the first push block 23 and the second push block 33, and the first guide rod 232 and the second guide rod 332 slide through the upper ends of the first movable plate 21 and the second movable plate 31 respectively, and the first rack 25 and the second rack 35 are respectively fixedly connected on one side of the lower ends of the first push block 23 and the second push block 33.

[0023] Specifically, the main structures of the first support and limit mechanism 2 and the second support and limit mechanism 3 are the same, the first movable plate 21 and the second movable plate 31, the first support bottom plate 22 and the second support bottom plate 32 are symmetrical about the vertical center line of the goods to be transferred 6, and the difference is that the first push block 23 and the second push block 33 are set at different positions, the length of the first guide rod 232 and the first spring 233 is smaller than the length of the second guide rod 332 and the second spring 333, and in the initial state, the first roller 231 and the second roller 331 are located on both sides of the goods to be transferred 6 and do not touch the goods to be transferred 6 When contacting and transferring the goods to be transferred 6, the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 are driven to move synchronously by starting the driving mechanism 4, so that the first roller 231 and the second roller 331 gradually approach the goods to be transferred 6. When the first roller 231 and the second roller 331 initially press the goods to be transferred 6, the distance from the first movable plate 21 to the goods to be transferred 6 is smaller than the distance from the second movable plate 31 to the goods to be transferred 6. In this state, the distance that the first movable plate 21 can continue to move toward the goods to be transferred 6 is smaller than the distance that the second movable plate 31 can continue to move.

[0024] The working principle of the present application is to initially press the upper end of the goods to be transferred 6 by the first roller 231 and the second roller 331, and then make the first roller 231 and the second roller 331 continue to move, and push the upper left corner of the goods to be transferred 6 by the first roller 231, so that the goods to be transferred 6 is turned to the right, and its right side is pressed against the second roller 331, and the second roller 331 plays a supporting and limiting role on the right side of the goods to be transferred 6 to prevent the goods to be transferred 6 from turning over or moving horizontally. When the goods to be transferred 6 is turned over, its lower left corner is tilted, and through the cooperation between the first support limiting mechanism 2 and the linkage mechanism 5, one end of the first support bottom plate 22 is moved to the bottom left side of the goods to be transferred 6, and then the first push block 23 and the first supporting base plate 22 are fixed in position, the second movable plate 31 and the second roller 331 continue to move, and by pressing against the upper right corner of the goods to be transferred 6, the lower right corner of the goods to be transferred 6 is vacated, and then through the cooperation with the linkage mechanism 5, the second supporting base plate 32 extends into the lower right corner of the goods to be transferred 6, and as the second roller 331 continues to push, the goods to be transferred 6 is straightened, and the bottom of the goods to be transferred 6 is stably placed on the first supporting roller 24 and the second supporting roller 34, and the second roller 331 and the first roller 231 press the goods to be transferred 6 from both sides to realize automatic loading and fixing, which not only improves the convenience of loading the goods to be transferred 6, but also ensures the stability of the goods to be transferred 6 during the transportation process.

[0025] In the present application, by providing a rotatable first roller 231, a second roller 331 and a first support roller 24, a second support roller 34, the friction between the goods to be transferred 6 and the goods to be transferred 6 can be reduced, the wear of the goods to be transferred 6 can be avoided, and the smoothness of the tilting and straightening process of the goods to be transferred 6 can be improved.

[0026] Furthermore, the linkage mechanism 5 includes a large gear 51, a third rack 53 and a pinion 55. The two large gears 51 and the pinion 55 are rotatably installed inside the upper and lower ends of the first movable plate 21 and the second movable plate 31 respectively. The two third racks 53 are fixedly installed inside the upper ends of the first support base plate 22 and the second support base plate 32 respectively. The mounting shafts of the large gears 51 and the pinion 55 on the same side are fixedly connected with a transmission wheel 54. The two transmission wheels 54 on the same side are sleeved with a transmission belt 52. The two large gears 51 are meshed with the first rack 25 and the second rack 35 respectively, and the two pinion gears 55 are meshed with the two third racks 53 respectively.

[0027] Specifically, in the initial state, the large gear 51 is not engaged with the first rack 25 and the second rack 35. When the first rack 25 follows the first push block 23 to move a certain distance, that is, when the first roller 231 and the second roller 331 are initially pressed against the goods 6 to be transferred, the large gear 51 is engaged with the first rack 25. At this time, the large gear 51 on the other side is not engaged with the second rack 35. When the first movable plate 21 and the second movable plate 31 continue to move with the driving mechanism 4, the large gear 51 rotates and drives the small gear through the transmission belt 52. The pinion 55 rotates synchronously, and the pinion 55 is meshed with the third rack 53, so that the third rack 53 moves toward the direction close to the goods to be transferred 6, so that one end of the first supporting bottom plate 22 extends below the lower left corner of the goods to be transferred 6. It should be noted that when the goods to be transferred 6 tilts, it squeezes the second roller 331 to the right, so that the second roller 331 moves a short distance to the right relative to the second movable plate 31. When the first supporting bottom plate 22 is in place at the lower left corner of the goods to be transferred 6, the second rack 35 is in contact with the lower left corner of the goods to be transferred. The second movable plate 31 is driven by the driving mechanism 4 to continue to move, driving the second roller 331 to move forward, and the second roller 331 pushes the upper right corner of the cargo 6 to be transferred. Since the lower left corner of the cargo 6 to be transferred is supported on the first supporting roller 24, when the right side is subjected to force, the lower right corner gradually hangs in the air, and the large gear 51 is driven to move by the second movable plate 31. The large gear 51 is engaged with the second rack 35, so that the large gear 51 rotates, thereby driving the small gear 55 on this side to rotate, and then the second support The bottom plate 32 extends into the lower right corner of the goods to be transferred 6. With the push of the second roller 331, the upper and lower ends of the left and right sides of the goods to be transferred 6 respectively drive the first roller 231, the second roller 331, the first support roller 24 and the second support roller 34 to rotate, so that the goods to be transferred 6 gradually return to the center and fall steadily on the first support bottom plate 22 and the second support bottom plate 32. The goods to be transferred 6 are supported by the first support bottom plate 22 and the second support bottom plate 32, and then the goods to be transferred 6 are transferred to the designated position by the transfer vehicle.

[0028] When putting down the goods to be transferred 6, the driving mechanism 4 drives the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 to move in opposite directions. Due to the different positions of the first pushing block 23 and the second pushing block 33, the first supporting bottom plate 22 is first withdrawn from the bottom of the goods to be transferred 6, and the goods to be transferred 6 is tilted toward the direction of the first supporting and limiting mechanism 2. The first roller 231 is initially pressed against the goods to be transferred 6, and then the second supporting bottom plate 32 is withdrawn from the bottom of the other side of the goods to be transferred 6, and the goods to be transferred 6 returns to the normal position. The second roller 331 is initially pressed against the goods to be transferred 6, and then, driven by the driving mechanism 4, it gradually breaks away from the contact with the goods to be transferred 6 to complete the material discharge.

[0029] Furthermore, the driving mechanism 4 includes a fixed box 41, a motor 42 and a bidirectional screw 43. The fixed box 41 is fixedly connected to one side of the two side plates 1. The motor 42 is fixedly installed at one end of the fixed box 41 for driving the bidirectional screw 43 to rotate. The bidirectional screw 43 is rotatably installed in the fixed box 41. Slide blocks 49 are threadedly sleeved on the rod bodies at both ends of the bidirectional screw 43. The two slide blocks 49 are respectively fixedly connected to one side of the first movable plate 21 and the second movable plate 31. A first connecting block 44 and a connecting rod 45 are fixedly connected in the bidirectional screw 43. The first connecting block 44 is fixedly connected to the connecting rod 45. A third spring 46 is sleeved on the connecting rod 45. One end of the third spring 46 is fixedly connected to the first connecting block 44, and the other end is fixedly connected to the second connecting block 47. The second connecting block 47 is rotatably installed on one side of a stop block 48. The stop block 48 is slidably connected in the fixed box 41, and the stop block 48 is movably sleeved on the connecting rod 45 and the bidirectional screw 43.

[0030] Specifically, the bidirectional screw rod 43 is divided into two sections, the first connecting block 44 and the connecting rod 45 are arranged between the two sections of the bidirectional screw rod 43, the first connecting block 44 is fixed to the end of one section of the bidirectional screw rod 43, and the connecting rod 45 is fixed to the end of the other section. The first connecting block 44 and the second connecting block 47 are connected by a third spring 46, the stop block 48 slides left and right along the inside of the fixed box 41, and the second connecting block 47 is rotatably connected to one side of the stop block 48. The stop block 48 is arranged on the side close to the first movable plate 21.

[0031] When in use, the starting motor 42 drives the bidirectional screw rod 43 and the first connecting block 44 to rotate, and the first connecting block 44 drives the third spring 46 and the second connecting block 47 to rotate synchronously, and the sliders 49 on both sides move inward along the bidirectional screw rod 43. During the movement, the slider 49 close to the side of the first movable plate 21 abuts against the stop block 48 and drives the stop block 48 to move synchronously, so that the third spring 46 contracts, and then the slider 49 disengages from the bidirectional screw rod 43 and moves to the position where the connecting rod 45 is located. At this time, the bidirectional screw rod 43 continues to rotate, and the slider 49 on this side no longer moves, so that the first movable plate 21 no longer continues to move. At this time, the first support bottom plate 22 has moved into place at the lower left corner of the goods to be transferred 6, and the slider 49 on the other side continues to move. Correspondingly, the second roller 331 pushes the goods to be transferred 6 back to the center, and the second support bottom plate 32 gradually moves to the lower right corner of the goods to be transferred 6 until the second support bottom plate 32 moves into place.

[0032] When unloading, the motor 42 drives the bidirectional screw rod 43 to rotate in the opposite direction, and the stop block 48 presses against the slider 49 under the elastic force of the third spring 46. When the bidirectional screw rod 43 rotates in the opposite direction, the slider 49 is threadedly matched with the bidirectional screw rod 43 and moves outward synchronously with the slider 49 on the other side. Correspondingly, the first support and limit mechanism 2 and the second support and limit mechanism 3 on both sides move outward synchronously, and the bottom of the first support and limit mechanism 2 first detaches from the goods to be transferred 6, and then the bottom of the second support and limit mechanism 3 detaches from the goods to be transferred 6. After the goods to be transferred 6 returns to the normal state, the upper parts of the first support and limit mechanism 2 and the second support and limit mechanism 3 detach from the upper parts of the goods to be transferred 6 in turn, completing the unloading of the goods to be transferred 6.

[0033] like Figure 1-Figure 11 As shown, a method for using a cargo transfer device provided by an embodiment of the present invention includes the following steps: S1: Move the device to the location of the goods to be transferred 6 by a transfer vehicle, so that the first support and limit mechanism 2 and the second support and limit mechanism 3 are respectively located on both sides of the goods to be transferred 6; S2: starting the driving mechanism 4 to drive the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 to move toward the direction close to the goods to be transferred 6, until the first roller 231 and the second roller 331 initially press against the goods to be transferred 6; S3: Then the driving mechanism 4 continues to drive the first supporting and limiting mechanism 2 and the second supporting and limiting mechanism 3 to move, and the first roller 231 pushes the upper left corner of the goods to be transferred 6, so that the goods to be transferred 6 turns to the right, and its lower left corner is tilted, and through the cooperation between the first supporting and limiting mechanism 2 and the linkage mechanism 5, one end of the first supporting bottom plate 22 moves to the bottom left side of the goods to be transferred 6 to support the lower left corner of the goods to be transferred 6; S4: the driving mechanism 4 drives the second movable plate 31 to continue to move, pressing against the upper right corner of the goods to be transferred 6, and pushes the goods to be transferred 6 to the left, so that the lower right corner of the goods to be transferred 6 is suspended, and the second support limit mechanism 3 cooperates with the linkage mechanism 5 to make the second support bottom plate 32 extend into the lower right corner of the goods to be transferred 6 to support the lower right corner of the goods to be transferred 6, and then the goods to be transferred 6 gradually return to the right position, and the second roller 331 and the first roller 231 press against the goods to be transferred 6 from both sides to complete automatic feeding and fixing; S5: Move the goods to be transferred 6 to the designated position through the transfer vehicle, and drive the bidirectional screw rod 43 to rotate in the opposite direction through the motor 42. The stop block 48 presses against the slider 49 under the elastic force of the third spring 46. When the bidirectional screw rod 43 rotates in the opposite direction, the slider 49 is threadedly matched with the bidirectional screw rod 43 and moves outward synchronously with the slider 49 on the other side. Correspondingly, the first support and limit mechanism 2 and the second support and limit mechanism 3 on both sides move outward synchronously, and the bottom of the first support and limit mechanism 2 first detaches from the goods to be transferred 6, and then the bottom of the second support and limit mechanism 3 detaches from the goods to be transferred 6. After the goods to be transferred 6 returns to the normal position, the upper parts of the first support and limit mechanism 2 and the second support and limit mechanism 3 detach from the upper parts of the goods to be transferred 6 in turn, completing the unloading of the goods to be transferred 6.

[0034] To sum up: this cargo transfer device, by arranging the first supporting and limiting mechanisms 2 and the second supporting and limiting mechanisms 3 with similar structures but different positions on both sides of the driving mechanism 4, can, when the driving mechanism 4 is started, the first supporting and limiting mechanisms 2 and the second supporting and limiting mechanisms 3 first preliminarily fix the cargo 6 to be transferred, and then the first supporting and limiting mechanisms 2 push the cargo 6 to be transferred to flip, and support the bottom of the flipped side, and then the second supporting and limiting mechanisms 3 push the cargo 6 to be transferred to return to the center, and during the return process, the bottom of the cargo 6 to be transferred is suspended in the air, and the second supporting and limiting mechanisms 3 support the bottom of the cargo 6 to be transferred, so that the cargo 6 to be transferred can be easily moved from the plane to the transfer vehicle, and after being transferred to the designated position, the materials can be unloaded and unloaded from the transfer vehicle.

10. A method for cargo transshipment, characterized in that: A cargo transfer device according to any one of claims 1 to 9, comprising the following steps: S1: using a transfer vehicle to move the device to the location of the goods to be transferred (6), so that the first support and limit mechanism (2) and the second support and limit mechanism (3) are respectively located on both sides of the goods to be transferred (6); S2: starting the driving mechanism (4) to drive the first supporting and limiting mechanism (2) and the second supporting and limiting mechanism (3) to move in a direction close to the goods to be transferred (6) until the first roller (231) and the second roller (331) initially press against the goods to be transferred (6); S3: Subsequently, the driving mechanism (4) continues to drive the first support and limit mechanism (2) and the second support and limit mechanism (3) to move, and the first roller (231) pushes the upper left corner of the goods to be transferred (6), so that the goods to be transferred (6) flips to the right, and its lower left corner is tilted. Through the cooperation between the first support and limit mechanism (2) and the linkage mechanism (5), one end of the first support bottom plate (22) moves to the bottom left side of the goods to be transferred (6), so as to support the lower left corner of the goods to be transferred (6); S4: the driving mechanism (4) drives the second movable plate (31) to continue to move, pressing against the upper right corner of the goods to be transferred (6), and pushing the goods to be transferred (6) to the left, so that the lower right corner of the goods to be transferred (6) is suspended in the air, and the second support limit mechanism (3) cooperates with the linkage mechanism (5) to make the second support bottom plate (32) extend into the lower right corner of the goods to be transferred (6) to support the lower right corner of the goods to be transferred (6), and then the goods to be transferred (6) gradually return to the normal position, and the second roller (331) and the first roller (231) press against the goods to be transferred (6) from both sides, completing automatic loading and fixing; S5: The goods to be transferred (6) are moved to the designated position by the transfer vehicle, and the motor (42) drives the bidirectional screw rod (43) to rotate in the opposite direction. The stop block (48) presses against the slider (49) under the elastic force of the third spring (46). When the bidirectional screw rod (43) rotates in the opposite direction, the slider (49) is threadedly engaged with the bidirectional screw rod (43) and moves outward synchronously with the slider (49) on the other side. Correspondingly, the first support and limit mechanism (2) and the second support and limit mechanism (3) on both sides move outward synchronously. The bottom of the first support and limit mechanism (2) first separates from the goods to be transferred (6), and then the bottom of the second support and limit mechanism (3) separates from the goods to be transferred (6). After the goods to be transferred (6) are returned to the normal position, the upper parts of the first support and limit mechanism (2) and the second support and limit mechanism (3) are separated from the upper parts of the goods to be transferred (6) in turn, thereby completing the unloading of the goods to be transferred (6).
