[0002] In a packaging production line, in order to improve the automation level during the packaging process, AGV transportation equipment is used to transport goods.

[0003] On the moving path of the AGV transportation equipment, there is a long inclined road surface. When the AGV transportation equipment tilts left and right during the forward movement (for a long time), since the goods placement area of the AGV transportation equipment is generally fixed, the transported goods will also tilt along with the AGV transportation equipment. When the stacking height of the transported goods is relatively high, the long-term inclined transportation is likely to cause the goods to move or even fall on the AGV transportation equipment, affecting the normal transportation of the goods.

[0008] Wherein, a pulling rope connected to the rotating mechanism is arranged on the moving plate. When the AGV forklift body is skewed and drives the installation box to tilt towards the end, the pushing member moves to press one side of the moving plate and makes it move, pulling the pulling rope to drive the rotating mechanism to rotate, so that the fork rotates to a horizontal position.

[0010] Among them, the mounting member is mounted on the moving member, the outer end of the mounting member is rotatably connected to the forklift fork, both sets of the mounting rings are rotatably sleeved on the mounting member, both sets of the mounting rings are respectively connected to two connecting members, one ends of two sets of the pulling ropes away from the moving plate are respectively cross-connected to the two connecting members, the two connecting members are symmetrically arranged and mutually attached, conductive members which are mutually attached are arranged on the two connecting members, a slotted groove is formed in the connecting member, a pulling block is slidably inserted into the slotted groove, a pushing mechanism is arranged in the slotted groove to push the pulling block to move and connect with the forklift fork, and the two conductive members are electrically connected to the pushing mechanism to connect the power supply of the pushing mechanism.

[0011] Preferably, a first mounting groove is formed in one side of the mounting member facing the forklift fork, a limiting member for inserting into the forklift fork is slidably inserted into the first mounting groove to limit the rotation of the forklift fork, an elastic element is arranged between the first mounting groove and the limiting member, an electromagnet is arranged in the first mounting groove, the limiting member is a magnetic member, and the electromagnet is electrically connected to the conductive member to control the power-off of the electromagnet.

[0016] Compared with the prior art, the beneficial effect of the present invention is that when the AGV forklift body is skewed left and right along the forward direction in this application, the mounting box will be tilted together, so that the pushing member moves inside the mounting box to press one moving plate and make it move, and the pulling rope drives the connecting member of the rotating mechanism to rotate, driving the forklift fork to rotate to the horizontal position, ensuring that the goods can still be in a relatively horizontal state when the AGV forklift body is tilted for a long time, and avoiding the movement and dropping of the transported goods.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figure 1 and Figure 2 , an AGV transportation device with an anti-falling mechanism, including: AGV forklift body 1, gantry 2, driving mechanism 3, fork 4 and moving part 5, etc.;

[0027] The gantry 2 is installed on the AGV forklift body 1. A moving part 5 is slidably arranged on the gantry 2 (the moving part 5 can move up and down at the gantry 2). The driving mechanism 3 is installed on the gantry 2. The driving mechanism 3 is connected to the moving part 5 and is used to drive the moving part 5 to move up and down at the gantry 2. The fork 4 is installed on the moving part 5;

[0028] It should be noted that during the process of transporting goods, the goods are stacked on the pallet, and the pallet is placed on the fork 4. The driving mechanism 3 drives the fork 4 to move up to lift the pallet and the goods; then the AGV forklift body 1 drives the goods to move;

[0029] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6, the rotating mechanism 7 on the moving part 5;

[0030] The rotating mechanism 7 includes a mounting part 71, a mounting ring 72 and a connecting part 73;

[0031] Among them, the mounting part 71 is mounted on the moving part 5, the outer end of the mounting part 71 is rotatably connected to the forklift fork 4, two groups of mounting rings 72 are rotatably sleeved on the mounting part 71 (the mounting ring 72 can rotate at the mounting part 71), two groups of mounting rings 72 are respectively connected to two groups of connecting parts 73, the two groups of connecting parts 73 are symmetrically arranged and fit together (distributed left and right), conductive parts 731 are provided on the sides of the two groups of connecting parts 73 close to each other, the two groups of conductive parts 731 fit together, a slot is opened on the connecting part 73, a pull block 74 is slidably inserted into the slot, and a pushing mechanism (such as an electric telescopic rod, a pneumatic or hydraulic telescopic rod and other telescopic devices) is provided in the slot for pushing the pull block 74 to move so that the pull block 74 is connected to the forklift fork 4 (a slot is opened on the side of the forklift fork 4 facing the connecting part 73, and when the pull block 74 moves outwards, it will be inserted into the slot, so that the movement of the connecting part 73 can drive the forklift fork 4 to move together), and the two groups of conductive parts 731 are electrically connected to the pushing mechanism through wires;

[0032] An installation box 6 is installed on the moving part 5. Two moving plates 9 are slidably provided on both sides of the inner cavity of the installation box 6 (the two moving plates 9 are located on the left and right sides of the installation box 6 and are horizontally arranged). The outer wall of the moving plate 9 and the inner wall of the installation box 6 are sealed. An elastic part 10 is provided between the moving plate 9 and the installation box 6 for supporting the moving plate 9, and a pushing part is provided in the installation box 6 between the two moving plates 9;

[0033] Further, the pushing part is liquid filled between the two moving plates 9; the pushing part is a pressing part 11;

[0034] Further, magnetic blocks 12 are provided on the sides of the two moving plates 9 close to each other, the pressing part 11 is a magnetic block, and the magnetic poles of the sides of the magnetic block and the magnetic block 12 close to each other are opposite; when the installation box 6 is restored to the horizontal position, due to the repulsive force between the magnetic block and the magnetic block 12, the magnetic block and the pressing part 11 are not in contact;

[0035] A pulling rope 8 is provided on the moving plate 9. The ends of the two pulling ropes 8 far from the moving plate 9 are respectively cross-connected to the two groups of connecting parts 73 (that is, the left pulling rope 8 is connected to the right moving plate 9, and the right pulling rope 8 is connected to the left moving plate 9);

[0036] Further, a blocking plate is installed on the forklift fork 4, and the blocking plate is located in front of the goods (the front side in the transportation direction). When the AGV forklift body 1 tilts forward, the goods are blocked from falling;

[0037] In summary, during the process of transporting goods, when the AGV forklift body 1 is tilted due to the skew of the road surface (tilting left and right along the forward direction), it will tilt the mounting box 6 together, causing the pushing member to move inside the mounting box 6 and press one side of the moving plate 9, and move it in the tilting direction; pulling the pulling rope 8 to drive the connecting member 73 of the rotating mechanism 7 to rotate, the two conductive members 731 will be separated, causing the pushing mechanism to work, pushing the pulling block 74 outward from the slot and inserting it into the slot of the fork 4, connecting the connecting member 73 with the fork 4. When the connecting member 73 moves, it will drive the fork 4 to rotate to the horizontal position (when the AGV forklift body 1 tilts to the left, the mounting box 6 tilts to the left, causing the pushing member to move leftward, pressing the left moving plate 9, and the movement of the left moving plate 9 will pull the right pulling rope 8, causing the right connecting member 73 to move, driving the fork 4 to rotate to the right. Conversely, when the AGV forklift body 1 tilts to the right, the right moving plate 9 will pull the left pulling rope 8, causing the left connecting member 73 to move and drive the fork 4 to rotate to the left), avoiding the movement and dropping of the transported goods due to long-term tilting.

[0038] Embodiment 2

[0039] As a preferred solution, please refer to FIGS. 3 Figure 4 and Figure 6 , a first installation groove 75 is provided on the side of the mounting member 71 facing the fork 4, a limiting member 76 is slidably inserted in the first installation groove 75, a limiting groove is provided on the side of the fork 4 facing the mounting member 71, and the limiting member 76 is inserted into the limiting groove to limit the rotation of the fork 4. An elastic element is provided between the first installation groove 75 and the limiting member 76, an electromagnet is provided in the first installation groove 75, and the limiting member 76 is a magnetic member (the magnetic poles of the magnetic block and the electromagnet on the side close to each other are the same, generating a repulsive force); the electromagnet is electrically connected to the conductive member 731 through a wire.

[0040] Furthermore, a spring is provided at the connection part of the connecting member 73 and the conductive member 731 to push the conductive member 731; when the moving amplitude of the connecting member 73 is small, due to the thrust of the spring, the conductive member 731 will move, making the two conductive members 731 continue to fit, so that the fork 4 will not rotate easily.

[0041] It should be noted that the fork 4 is restricted by the limiting member 76 so that the fork 4 will not rotate easily. When the AGV forklift body 1 tilts slightly or for a short time, the fork 4 will not rotate, avoiding the pull-back swing of the fork 4 (due to short-term tilting) and preventing the movement of the goods caused thereby; when the two conductive members 731 are separated, the electromagnet will be powered off, the repulsive force received by the limiting member 76 will disappear, and through the action of the elastic element, the limiting member 76 will be removed from the fork 4, enabling the fork 4 to rotate.

[0042] Embodiment 3

[0043] As a preferred solution, please refer to Figure 3 and Figure 5 , a second installation groove 13 is formed at the edge of the moving plate 9. A rubber pad 14 that fits against the inner wall of the installation box 6 is provided in the second installation groove 13. Through holes 15 communicating with the second installation groove 13 are formed on one side of each of the two moving plates 9 away from each other. A liquid (water) is filled on one side of each of the two moving plates 9 away from each other, and the liquid is located at both ends of the installation box 6;

[0044] It should be noted that when the pushing member drives one of the moving plates 9 to move, the greater the inclination of the AGV forklift body 1, the greater the movement of the moving plate 9, which will reduce the distance between the moving plate 9 and the end of the installation box 6 here, and squeeze the liquid into the inner cavity of the second installation groove 13 through the through holes 15, increasing the pressure of the rubber pad 14 in contact with the inner wall of the installation box 6, thereby increasing the friction force between the two (and the friction force increases with the increase of the inclination amplitude); when the installation box 6 returns from a large inclination to the horizontal state, the moving speed of the moving plate 9 starts slowly to avoid the too fast reset speed of the fork 4 caused by the too fast moving speed of the moving plate 9 (when the installation box 6 returns from an area with a large inclination, the turning amplitude of the fork 4 will also be large. If the speed is too fast, the goods above the fork 4 are likely to move), preventing the transported goods from falling.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
