Detailed implementation manners

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] The embodiments of the present application provide a material carrying device and an automatic guided vehicle, which are used to solve the technical problem that the position of the material carrying device in the related art is fixed, which is not convenient for staff to load and unload materials.

[0028] To make the invention purpose, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the following described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 7 , the embodiments of the present application provide a material carrying device, including: a carrying mechanism 20, a lifting mechanism 20, and a moving mechanism 30; the carrying mechanism 20 is provided with a loading table 11 for carrying materials; the lifting mechanism 20 is connected to the loading table 11, and the lifting mechanism 20 includes a driving component 21, a transmission component 22, and a lifting component 23; both the driving component 21 and the lifting component 23 are in transmission connection with the transmission component 22, and the driving component 21 is used to drive the transmission component 22 to rotate, driving the lifting component 23 to move up and down, so that the loading table 11 rises or falls; the moving mechanism 30 is connected to the lifting component 23.

[0030] For example, such asFigure 1 and Figure 2 As shown in Figure 2 , the driving assembly 21 and the transmission assembly 22 can be arranged on the loading platform 11, and the lifting assembly 23 can be arranged below the loading platform 11 to support the loading platform 11 and move up and down under the driving action of the driving assembly 21 and the transmission assembly 22, so that the loading platform 11 rises in the vertical direction.

[0031] In the embodiment of the present application, the driving assembly 21 can be driven by a motor, a hydraulic device, a gear structure, etc. The transmission assembly 22 can transmit power through friction and friction drive, or can transmit power or motion through meshing of the internal master-slave structure or by means of an intermediate structure.

[0032] The moving mechanism 30 can be connected to the lifting assembly 23. The moving mechanism 30 can include a sliding structure to facilitate the movement of the material carrying device on the ground. Specifically, when the material carrying device only needs to move a short distance, the staff can directly push the material carrying device, so that the material carrying device moves under the sliding action of the moving mechanism 30 and the ground, thus eliminating the need for the automatic guided vehicle to repeatedly perform the tasks of identification and handling in a short time.

[0033] The embodiment of the present application provides a material carrying device, including: a carrying mechanism 20, a lifting mechanism 20 and a moving mechanism 30; the carrying mechanism 20 is provided with a loading platform 11 for carrying materials; the lifting mechanism 20 is connected to the loading platform 11, and the lifting mechanism 20 includes a driving assembly 21, a transmission assembly 22 and a lifting assembly 23; both the driving assembly 21 and the lifting assembly 23 are in transmission connection with the transmission assembly 22, and the driving assembly 21 is used to drive the transmission assembly 22 to rotate, driving the lifting assembly 23 to move up and down, so that the loading platform 11 rises or falls; the moving mechanism 30 is connected to the lifting assembly 23. In the present application, the moving mechanism 30 can make it more convenient for the staff to move the loading platform 11. Therefore, when the distance that the material carrying device needs to move is short, there is no need to use the small vehicle of the automatic guided vehicle for handling; when the materials on the loading platform 11 are stacked relatively high, the driving assembly 21, the transmission assembly 22 and the lifting assembly 23 can drive the lifting assembly 23 to move downward through their transmission connection, so that the loading platform 11 descends; when the storage position of the materials is relatively high, the driving assembly 21, the transmission assembly 22 and the lifting assembly 23 can drive the lifting assembly 23 to move upward through their transmission connection, so that the loading platform 11 rises to a height similar to that of the stored materials, thus facilitating the staff to load and unload materials.

[0034] In one embodiment, the moving mechanism 30 includes: a moving member 31, a first fixing member 32, and a switching member 33; the switching member 33 is rotatably connected to the lifting assembly 23, and the switching member 33 is connected to the moving member 31 and the first fixing member 32 for switching between the moving member 31 and the first fixing member 32.

[0035] As Figure 3 shown, both the moving member 31 and the first fixing member 32 are connected to the switching member 33, and the switching member 33 is rotatably connected to the lifting assembly 23, so that the switching member 33 can rotate relative to the lifting assembly 23, and during the rotation relative to the lifting assembly 23, the moving member 31 and the first fixing member 32 are alternately switched. Specifically, when it is necessary to move the material carrying device over a short distance, the switching member 33 can be rotated relative to the lifting assembly 23 until the moving member 31 contacts the ground, so that when the staff pushes the material carrying device, the moving member 31 slides relative to the ground. When it is necessary to fix the material device, the switching member 33 can be rotated relative to the lifting assembly until the first fixing member 32 contacts the ground to fix and support the lifting assembly 23.

[0036] Exemplarily, the moving mechanism 30 in the embodiment of the present application can be provided with a self-locking structure to avoid sudden switching between the moving member 31 and the first fixing member 32, so as to improve the stability of the moving mechanism 30.

[0037] The moving member 31 in the embodiment of the present application can be a universal wheel, and the first fixing member 32 can be a base for fixing and supporting the lifting assembly 23.

[0038] In one embodiment, when the switching member 33 rotates relative to the lifting assembly 23 to form a first angle with the horizontal direction, the first fixing member 32 contacts the ground to fix the position of the loading platform 11 in the horizontal direction; when the switching member 33 rotates relative to the lifting assembly 23 to form a second angle with the horizontal direction, the moving member 31 slides relative to the ground to change the position of the loading platform 11 in the horizontal direction.

[0039] Specifically, when the switching member 33 rotates relative to the lifting assembly 23 to form a first angle with the horizontal direction, the moving member 31 does not contact the ground, and the first fixing member 32 contacts the ground to fix and support the lifting assembly 23, thereby fixing the position of the loading platform 11 in the horizontal direction and preventing the staff from accidentally pushing the material carrying device. When the switching member 33 rotates relative to the lifting assembly 23 to form a second angle with the horizontal direction, the first fixing member 32 does not contact the ground, and the moving member 31 contacts the ground and slides relative to the ground, thereby changing the position of the loading platform 11 in the horizontal direction to facilitate the staff to move the cabinet material carrying device over a short distance.

[0040] Exemplarily, the first angle in the embodiments of the present application may be greater than the second angle, and those skilled in the art can set the magnitudes of the first angle and the second angle according to actual situations.

[0041] In one embodiment, the driving assembly 21 includes: a first bevel gear 211, a rotating member 212, and a second fixing member 213. The first bevel gear 211 is in transmission connection with the transmission mechanism to drive the transmission mechanism to rotate; the rotating member 212 is disposed above the first bevel gear 211 and is rotatably connected to the first bevel gear 211; the second fixing member 213 is disposed between the rotating member 212 and the first bevel gear 211 and is used to fix the rotating member 212 when the loading table 11 rises to a preset height.

[0042] As Figure 4 shown, the rotating member 212 is disposed above the first bevel gear 211, and the first bevel gear 211 is in transmission connection with the transmission assembly 22. When the rotating member 212 rotates, the first bevel gear 211 rotates to drive the transmission assembly 22 to rotate, so that the lifting assembly 23 moves up and down.

[0043] Exemplarily, a second fixing member 213 may be disposed between the rotating member 212 and the first bevel gear 211, and the second fixing member 213 can provide a supporting force for the rotating member 212. Furthermore, the second fixing member 213 can also fix the rotating member 212 when the rotating member 212 rotates and the loading table 11 rises to a preset height, avoiding the reverse rotation of the rotating member 212.

[0044] In one embodiment, the transmission assembly 22 includes: a second bevel gear 221, a first transmission rod 222, and a second transmission rod 223; the first transmission rod 222 is disposed on the loading table 11, and at least one first transmission rod 222 is in transmission connection with the first bevel gear 211 through the second bevel gear 221, and the plurality of first transmission rods 222 are in transmission connection with each other through the second bevel gear 221; the second transmission rod 223 is disposed on the lifting assembly 23 and is in transmission connection with the first transmission rod 222 through the second bevel gear 221 to drive the lifting assembly 23 to move up and down.

[0045] For example, as Figure 5 and Figure 6As shown in the figure, the first transmission rod 222 is arranged on the material loading platform 11. Second bevel gears 221 are arranged at both ends of the first transmission rod 222. The second transmission rod 223 is arranged on the lifting assembly 23. A second bevel gear 221 is arranged at one end of the second transmission rod 223. At least one first transmission rod 222 can be in transmission connection with the first bevel gear 211 through the second bevel gear 221. Multiple first transmission rods 222 can be in transmission connection with each other through the second bevel gear 221. The second transmission rod 223 can be in transmission connection with the first transmission rod 222 through the second bevel gear 221. When the rotating part 212 is rotated, the first bevel gear 211 drives the first transmission rod 222 to rotate, and then drives the second transmission rod 223 to rotate, so that the lifting assembly 23 moves up and down, thereby causing the material loading platform 11 to rise or fall in the vertical direction. Through the transmission effect among the second bevel gear 221, the first transmission rod 222 and the second transmission rod 223, multiple lifting assemblies 23 can be controlled, which can not only improve the stability of the up and down movement of the lifting assembly 23, but also does not require a large amount of manpower.

[0046] In one embodiment, the lifting assembly 23 includes: a fixed column 231 and a sliding column 232. The fixed column 231 is threadedly connected to one end of the second transmission rod 223; the sliding column 232 is connected to the other end of the second transmission rod 223. The sliding column 232 can move up and down relative to the fixed column 231 under the rotation of the second transmission rod 223.

[0047] As Figure 6 shown in the figure, a moving mechanism 30 is connected below the fixed column 231, and the inner side of the fixed column 231 can be threadedly connected to one end of the second transmission rod 223. The sliding column 232 is connected to the other end of the second transmission rod 223. When the second transmission rod 223 rotates relative to the fixed column 231, the sliding column 232 can move up and down relative to the fixed column 231, thereby driving the material loading platform 11 to rise or fall. Through the threaded connection effect between the second transmission rod 223 and the fixed column 231, and the moving effect of the sliding column 232 relative to the fixed column 231, the rise or fall of the material loading platform 11 is realized, and the structure is simple.

[0048] Exemplarily, a plurality of second through holes 233 are opened in both the fixed column 231 and the sliding column 232, and the second through holes 233 of the fixed column 231 and the second through holes 233 of the sliding column 232 correspond to each other one by one. The plurality of second through holes 233 are arranged at intervals in the vertical direction.

[0049] For example, the rotating member 212 can be provided with multiple gears. When the rotating member 212 rotates one gear, the sliding column 232 can move a preset distance relative to the fixed column 231, and the preset distance can be the distance between two second through holes 233. At the same time, a long bar matching the aperture distance can be inserted into the corresponding second through holes 233 of the fixed column 231 and the sliding column 232 to prevent the sliding column 232 from sliding down due to the large weight of the material on the loading platform 11. Through the dual fixing effects of the long bar and the second fixing member 213, the stability of the loading platform 11 can be further improved.

[0050] In one embodiment, the carrying mechanism 20 further includes: a protection component 12; the protection component 12 is disposed around the loading platform 11 and sleeved on the first transmission rod 222 and the second bevel gear 221.

[0051] As Figure 1 shown, for example, the shape of the loading platform 11 can be rectangular, and the protection component 12 can be disposed on at least two sides of the loading platform 11, and the protection component 12 can be sleeved on the first transmission rod 222 and the second bevel gear 221, which can not only protect the first transmission rod 222 and the second bevel gear 221, but also prevent the material on the loading platform 11 from falling. In addition, the protection component 12 of the embodiment of the present application can be disposed on three sides of the loading platform 11, and the other side can facilitate the staff to load and unload materials.

[0052] In one embodiment, the carrying mechanism 20 further includes: a limiting frame 13 and a fastener 14; the limiting frame 13 is disposed on the side of the loading platform 11; the fastener 14 is disposed below the loading platform 11.

[0053] As Figure 1 and Figure 7 shown, the carrying mechanism 20 in the embodiment of the present application can further include a limiting frame 13 and a fastener 14. The limiting frame 13 is disposed on the side of the loading platform 11 to facilitate the staff to move the loading platform 11 by pushing the limiting frame 13.

[0054] The fastener 14 can be a hook, and the number of hooks can be set according to actual situations, and no specific limitation is made here. The fastener 14 can be disposed below the loading platform 11. When there is a large amount of material stacked on the loading platform 11, the material on the loading platform 11 can be wound up by a rope and the fastener 14 to fix the material.

[0055] In one embodiment, the material carrying device further includes: a first cover plate 40 and a second cover plate 50. The first cover plate 40 is disposed below the loading platform 11, and the first cover plate 40 is provided with a notch 41 for placing an identification code; the second cover plate 50 abuts against the first cover plate 40, and the second cover plate 50 is provided with at least two mounting portions 51, and a first through hole 52 is formed between the two mounting portions 51, and the first through hole 52 corresponds to the notch 41.

[0056] As shown Figure 7 in the figure, the first cover plate 40 is arranged below the loading platform 11, and the first cover plate 40 is provided with a notch 41 for pasting the identification code. The shape of the notch 41 can match the shape of the identification code. The notch 41 in the embodiment of the present application can be a square notch.

[0057] The second cover plate 50 abuts against the first cover plate 40. The second cover plate 50 can be provided with at least two mounting parts 51. A through hole corresponding to the notch 41 can be formed between the two mounting parts 51. When the vehicle body of the automatic guided vehicle moves to the lower part of the loading platform 11, the identification code pasted in the notch 41 can be recognized through the through hole on the second cover plate 50. After successful recognition, the material carrying device can be engaged with the vehicle body of the automatic guided vehicle through at least two mounting parts 51 to increase the friction between the material carrying device and the vehicle body of the automatic guided vehicle, thereby improving the stability during the handling process.

[0058] As shown Figures 1 to 7 in the figure, the present application further provides an automatic guided vehicle, including a vehicle body (not shown in the figure) and the above-mentioned material carrying device. The material carrying device is installed above the vehicle body through the mounting part 51.

[0059] It can be understood that the automatic guided vehicle has all the technical effects of the material carrying device as described above, that is, through the moving mechanism 30, it is more convenient for the staff to move the material carrying device. Therefore, when the distance that the material carrying device needs to move is short, there is no need to repeatedly use the vehicle body of the automatic guided vehicle for handling; when the materials on the loading platform 11 are stacked relatively high, the driving component 21, the transmission component 22 and the lifting component 23 can drive the lifting component 23 to move downward through their transmission connection, so that the loading platform 11 descends; when the storage position of the materials is relatively high, the driving component 21, the transmission component 22 and the lifting component 23 can drive the lifting component 23 to move upward through their transmission connection, so that the loading platform 11 rises to be about the same height as the storage position of the materials, thus facilitating the staff to load and unload materials.
