Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, in particular to an explosion-proof clamping AGV. Background Art
[0002] AGVs are widely used in the transportation process of warehousing and production line systems. A large number of laser forklift AGVs are required to carry out material flow between the warehousing system and the production station, between production processes, and after processing is completed and returned to the warehousing system. Laser forklift AGVs, also known as laser-guided forklift AGVs, utilize a laser system installed on the AGV to carefully locate the workpiece according to the planned path, independently completing the transportation of workpieces without human operation. They are characterized by a high degree of automation and high transportation efficiency. With the development of automation, various types of automated production lines have been widely used. Currently, various types of AGVs are emerging on the market. Sometimes, due to the type of goods, the variety of goods, the workshop space, or other factors that limit the transportation and retrieval of goods at each workstation, conventional AGVs have significant limitations when handling and retrieving goods, such as cumbersome retrieval operations and low retrieval efficiency.
[0003] Currently, the forklift-type AGVs on the market have, to a certain extent, improved the shortcomings of AGVs in picking up and transporting goods. AGVs are used in conjunction with forklifts, with goods being moved to the AGV by the forklift. When the goods are moved to a specific location, the forklift is used to unload the goods. However, the forklift forks on existing AGVs can only be raised and lowered synchronously to support picking up and transporting goods. The positions of the two forks are relatively fixed and cannot be well adapted to picking up goods of various lengths. The relative position of the goods on the forks cannot be adjusted, limiting the use scenarios. The forklift forks on the AGV need to be equipped with different sizes, resulting in poor compatibility, high costs, and low handling efficiency. Utility Model Content

[0027] The following is combined with Figure 1-5 , the embodiments of the utility model are further described in detail.
[0028] An explosion-proof clamping AGV1, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes a body structure 2, a lifting adjustment mechanism 3 provided on the body structure 2, a horizontal adjustment mechanism 4 fixedly connected to the lifting adjustment mechanism 3, and a fork connected to the horizontal adjustment mechanism 4. The fork includes a first fork 51 and a second fork 52. The horizontal adjustment mechanism 4 includes a first adjustment component 41 connected to the first fork 51 and a second adjustment component 42 connected to the second fork 52. The first adjustment component 41 and the second adjustment component 42 are horizontally staggered along the forking direction of the forks, and the distal ends of the first fork 51 and the second fork 52 are aligned. The first adjustment component 41 and the second adjustment component 42 are used to drive the first fork 51 and the second fork 52 to move away from or towards each other.
[0029] Among them, the first adjustment component 41 is connected to the first fork 51, and the second adjustment component 42 is connected to the second fork 52. Both can adjust the horizontal position of the corresponding fork. The distance between the first fork 51 and the second fork 52 can be adjusted to adapt to goods 7 of different sizes. It has strong compatibility, simple and fast adjustment, low cost, and can also improve the stability of the goods 7 during transportation. Moreover, the first adjustment component 41 and the second adjustment component 42 are horizontally staggered along the fork direction of the fork, and the far ends of the first fork 51 and the second fork 52 are flush. The adjustable range of the distance can be increased, the structure is more compact, and it is convenient to transport the goods 7.
[0030] In this embodiment, the first fork 51 and the second fork 52 are box-type fork structures, used for left and right clamping and carrying box-type cargo 7. The horizontal position of the first fork 51 is adjusted by the first adjustment assembly 41, and the horizontal position of the second fork 52 is adjusted by the second adjustment assembly 42. This allows the first fork 51 and the second fork 52 to accommodate box-type cargo 7 of various sizes, improving handling efficiency and effectively preventing uneven force on the box-type cargo 7 during handling, which could cause the box to split and damage the cargo 7.
[0031] In this embodiment, please refer to Figure 3 、 Figure 4 、 Figure 5 The first adjustment assembly 41 includes a first adjustment motor 411, a first support plate 412, a first fixed plate 413, a first gear 414 and a first rack 415. One side of the first support plate 412 is slidably connected to the vehicle body mechanism 2 in the height direction, and the output shaft of the first adjustment motor 411 passes through the first support plate 412 and is connected to the first gear 414. The length direction of the first rack 415 is arranged on the side of the first fixed plate 413 facing the first support plate 412 along the adjustment direction of the first fork 51. The first rack 415 is meshed and connected with the first gear 414, which makes the transmission more stable and the bearing strength higher. It can also be adjusted and stopped at will, playing the role of fixed limit. The first fixed plate 413 is slidably connected to the other side of the first support plate 412, and the proximal end of the first fork 51 is fixedly connected to the other side of the first fixed plate 413, which has high installation and disassembly efficiency.
[0032] In some embodiments, two first guide rails 417 are arranged at intervals along the height direction on the other side of the first support plate 412, and a first slider is correspondingly provided on the first fixed plate 413. The first fixed plate 413 and the first support plate 412 are slidably connected through the first guide rail 417 and the first slider. The first rack 415 and the first gear 414 are both located between the two first guide rails 417, which has a compact structure and a better driving effect.
[0033] In some embodiments, the structure of the second adjustment assembly 42 is identical to that of the first adjustment assembly 41, saving costs. The second adjustment assembly 42 includes a second adjustment motor 421, a second support plate 422, a second fixed plate 423, a second gear 424, and a second rack 425. One side of the second support plate 422 is slidably connected to the vehicle body 2 in the height direction. The output shaft of the second adjustment motor 421 passes through the second support plate 422 and is connected to the second gear 424. The length direction of the second rack 425 is arranged on the side of the second fixed plate 423 facing the second support plate 422 along the adjustment direction of the second fork 52. The second rack 425 is meshed with the second gear 424, providing more stable transmission and higher load-bearing strength. It can also be adjusted and stopped, serving as a fixed limit. The second fixed plate 423 is slidably connected to the other side of the second support plate 422, and the proximal end of the second fork 52 is fixedly connected to the other side of the second fixed plate 423.
[0034] The output shaft of the first regulating motor 411 is arranged horizontally, while the output shaft of the second regulating motor 421 is arranged vertically. This avoidance arrangement results in a more compact structure and reduces space usage. Specifically, the output shaft of the first regulating motor 411 is in transmission connection with the first reducer 416, which passes through the first support plate 412 and is connected to the first gear 414. The output shaft of the second regulating motor 421 is in transmission connection with the second-stage second reducer 426, which passes through the second support plate 422 and is connected to the second gear 424.
[0035] In some embodiments, a gap is provided between the first support plate 412 and the second support plate 422, and an overlapping area exists along the conveying direction. The width of the gap is greater than the distance between the first support plate 412 and the first fixing plate 413. This facilitates movement of the first fixing plate 413 to the overlapping area, minimizes the distance between the first fork 51 and the second fork 52, and improves the compatibility of the equipment.
[0036] In some embodiments, the horizontal adjustment mechanism 4 further includes two limit plates 43, one each provided at the upper and lower ends of the first support plate 412 and the second support plate 422 in the overlapping region. The limit plates 43 are spaced apart with a first limit slot and a second limit slot. The end of the first support plate 412 is secured within the corresponding first limit slot, and the end of the second support plate 422 is secured within the corresponding second limit slot. This ensures the connection strength and relative positional stability between the first support plate 412 and the second support plate 422, thereby improving adjustment efficiency and accuracy and ensuring the stability of the relative positional relationship between the first fork 51 and the second fork 52.
[0037] In some embodiments, a photographing component 6 is provided between the first fork 51 and the second fork 52. The photographing component 6 is used to take a QR code to determine the current position, ensure that the movement reaches the set route position, and improve the control accuracy and the efficiency of conveying materials.
[0038] During operation, the conveying route for transporting the goods 7 is introduced into the control system of the vehicle body mechanism 2 in advance, and the camera 6 can capture the QR code on the ground to confirm the accuracy of the operation route. The control system adjusts the distance between the first fork 51 and the second fork 52 according to the size of the goods 7 to be transported. The position of the first fork 51 or the second fork 52 can be adjusted separately, or the positions of the first fork 51 and the second fork 52 can be adjusted simultaneously to improve the efficiency of adjustment. The forward and reverse rotation of the first adjustment motor 411 and the second adjustment motor 421 can realize the first rack 415 and the second rack 425 to move toward or in the opposite direction through the first gear 414 and the second gear 424, so as to realize the first fixed plate 413 and the first fork 51 thereon, and the second fixed plate 423 and the second fork 52 thereon to move closer to or farther away from each other.
[0039] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
