Description

Technical Field

[0001] The utility model relates to the technical field of AGV transportation, and more specifically, to an AGV transportation vehicle. Background Art

[0002] AGVs, short for automated guided vehicles, are capable of moving materials autonomously along predetermined paths or through advanced navigation technology without direct human intervention. The construction of subway tunnels and stations requires the transport of large quantities of building materials such as rebar, concrete, and formwork. AGVs can autonomously transport these materials along predetermined tracks or paths. AGVs can also be used for equipment handling and waste removal within stations, improving construction site safety and cleanliness. AGVs in subway construction not only improve efficiency but also reduce labor costs and optimize logistics management.

[0003] However, the current AGV transport vehicles only place materials on the top and lack corresponding protective structures for materials of different sizes or quantities. During the movement and transportation of the AGV transport vehicle, especially when turning, stopping suddenly or bumping, it will cause the materials to shift or even fall, which can easily cause collision damage to the materials and poor transportation effect.

[0004] Therefore, it is necessary to provide an AGV transport vehicle to solve the above technical problems. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figure 1-8 , an AGV transport vehicle, comprising a transport vehicle body 1, and further comprising:

[0038] A load-bearing plate 2 is provided on the transport vehicle body 1, a front baffle 3 is provided on the load-bearing plate 2, and a guide rod 4 is provided on the front baffle 3;

[0039] The rear baffle 5 is detachably mounted on the carrier plate 2. A through-hole is provided on the rear baffle 5 for slidingly engaging with the guide rod 4. The rear baffle 5 is provided with a plurality of transmission groups, each comprising a transmission mechanism 6 and two movably mounted side baffles 7. The transmission mechanism 6 is used to drive the two side baffles 7 toward or away from each other.

[0040] The limiting mechanism 9 limits the position of the rear baffle 5 by cooperating with the guide rod 4 .

[0041] When using the transport vehicle body 1 to transport materials for subway construction, the rear baffle 5 can be removed from the load plate 2 before loading the materials onto the load plate 2 of the transport vehicle body 1. Removing the rear baffle 5 greatly facilitates loading the materials, so that one end of the materials is against the front baffle 3. After the materials are loaded, the rear baffle 5 is placed on the load plate 2, and the guide rod 4 is inserted through the perforation of the rear baffle 5, so that the rear baffle 5 slides along the guide rod 4, and finally the rear baffle 5 is close to the other side of the materials. Then, the limiting mechanism 9 is passed through the end of the guide rod 4. When the limiting mechanism 9 is moved to the end of the rear baffle 5 away from the materials, the position of the rear baffle 5 is finally limited by the limiting mechanism 9. At this time, the rear baffle 5 can block the other end of the materials. By cooperating with the front baffle 3, the front and rear sides of the materials are limited. The position of the rear baffle 5 can be adjusted according to the length of the materials. After that, the transmission mechanism 6 on the rear baffle 5 is operated to move the side baffles 7 on the left and right sides toward or away from each other, at which time the side baffles 7 on both sides are brought closer to each other, and finally the left and right sides of the material are restricted by the side baffles 7, and the distance between the side baffles 7 on both sides can be adjusted according to the different widths of the materials. In summary, it can be seen that the materials on the carrying plate 2 can be protected by the front baffle 3, the rear baffle 5 and the side baffles 7, and the positions of the rear baffle 5 and the side baffles 7 can be adjusted according to the different sizes or quantities of materials, which can meet the transportation protection needs of a variety of materials, make the materials more stable during transportation, greatly prevent the materials from being offset or even tipping over during transportation, effectively avoid the materials from being damaged by collisions, and significantly improve the transportation effect. It is highly practical and can be widely promoted and used.

[0042] In this embodiment, preferably, please refer to Figure 1 and Figure 3-5 , a plurality of limiting holes 8 are provided on the guide rod 4, and the limiting mechanism 9 includes:

[0043] The limiting sleeve 91 has a through hole 92 in the middle thereof which is adapted to the guide rod 4; the limiting block 93 is telescopically arranged in the through hole 92 and is adapted to the limiting hole 8, and a linkage assembly 94 is provided in the limiting sleeve 91 for driving the limiting block 93 to move.

[0044] First, the limit block 93 can be moved through the linkage assembly 94 to shrink it into the limit sleeve 91, and then the guide rod 4 can be passed through the through hole 92 of the limit sleeve 91, that is, the limit sleeve 91 can slide along the guide rod 4 at this time. After the limit sleeve 91 is moved to the appropriate position of the rear baffle 5, the linkage assembly 94 is no longer operated, and the limit block 93 will be moved out, so that the limit block 93 is at the position of the corresponding limit hole 8 on the guide rod 4. The limit block 93 will move into the limit hole 8, thereby limiting the limit sleeve 91 on the guide rod 4, that is, the limit sleeve 91 can limit the position of the rear baffle 5.

[0045] In this embodiment, preferably, please refer to Figure 5 The limiting sleeve 91 defines an inner groove 10 that is slidably connected to the limiting block 93. A first elastic member 11 is disposed between the inner end of the limiting block 93 and the inner wall of the inner groove 10. The first elastic member 11 in the present application can be a spring. By operating the linkage assembly 94, the limiting block 93 can be moved into the inner groove 10 and compress the first elastic member 11. When the linkage assembly 94 is no longer operated, the rebound force of the first elastic member 11 can drive the limiting block 93 to move out of the inner groove 10 and return to its initial state.

[0046] In this embodiment, preferably, please refer to Figure 3-5 The linkage assembly 94 includes a linkage groove 941 and a channel 942 provided in the limiting sleeve 91. The two ends of the channel 942 are respectively connected to the linkage groove 941 and the inner groove 10. A pressure block 943 is slidably connected in the linkage groove 941. A traction rope 944 is provided on the pressure block 943. The other end of the traction rope 944 is connected to the limiting block 93. When the pressure block 943 is pressed, the pressure block 943 moves toward the inside of the linkage groove 941. The pressure block 943 simultaneously pulls the traction rope 944, which drives the limiting block 93 toward the inside of the inner groove 10. When the pressure block 943 is released, the rebound force of the first elastic member 11 drives the limiting block 93 to move out of the inner groove 10, and the limiting block 93 pulls the traction rope 944. At this time, the traction rope 944 drives the other end of the pressure block 943 to move out of the linkage groove 941, and finally the pressure block 943 returns to its initial state.

[0047] In this embodiment, preferably, please refer to Figure 3-5 , further comprising a butt plate 12, a plurality of dampers 13 and a second elastic member 14 are provided between the butt plate 12 and the limiting sleeve 91, and the second elastic member 14 is sleeved on the outside of the damper 13. The second elastic member 14 in the present application can be a spring, and when the limiting sleeve 91 is moved to the appropriate position of the rear baffle 5, the butt plate 12 is made to stick to the rear baffle 5, and then the position of the limiting sleeve 91 and the limiting block 93 is adjusted left and right, so that the limiting block 93 can enter the limiting hole 8 at the corresponding position. At this time, the second elastic member 14 and the damper 1 are in a compressed state, so that they can stick closely to the rear baffle 5, ensuring the blocking and protection of the material. Moreover, when the rear baffle 5 is subjected to forces such as bumps, it will also play a certain buffering role through the damper 1 and the second elastic member 14, reducing damage to the material, and having strong practicality.

[0048] In this embodiment, preferably, please refer to Figure 1-2 and Figure 7 , a shift groove 15 is provided on the rear baffle 5, and the transmission mechanism 6 includes:

[0049] The transmission chamber 61 is opened in the rear baffle 5 and communicates with the shift groove 15. A screw rod 62 is rotatably provided on the inner wall of the transmission chamber 61, and the screw rod 62 is provided with two sections of threads with opposite rotation directions; there are two nut seats 63 and they are respectively threadedly connected to the two sides of the screw rod 62. A connecting rod 64 is provided on the nut seat 63, and the other end of the connecting rod 64 is connected to the side baffle 7. The inner wall of the transmission chamber 61 is provided with a sliding rod 65 that movably passes through the nut seat 63.

[0050] By rotating the screw rod 62, the nut seats 63 on both sides can be driven to move closer to or away from each other, and the nut seat 63 will drive the connecting rod 64 connected to it to move together, and the connecting rod 64 will drive the side baffle 7 to move; at the same time, the nut seat 63 will slide along the connecting rod 64, which can improve the movement stability of the nut seat 63 and limit the rotation of the nut seat 63 to keep it moving horizontally.

[0051] One end of the screw rod 62 extends to the outside of the rear baffle 5 and is connected to the rotating wheel 21. By rotating the rotating wheel 21, the screw rod 62 can be driven to rotate, which can make the screw rod 62 rotate more conveniently and quickly.

[0052] In this embodiment, preferably, please refer to Figure 1-3 and Figure 8 , further comprising a splicing plate 16, a splicing groove 17 is provided on the splicing plate 16 and the side baffle 7, and the splicing plate 16 is provided with an insert 18 adapted to the splicing groove 17. When the distance between the front baffle 3 and the rear baffle 5 is large, the splicing plate 16 can be taken out and its insert 18 can be inserted into the splicing groove 17 of the side baffle 7. At this time, the splicing plate 16 can be connected to the side baffle 7, increasing the blocking length of the side baffle 7. Subsequently, another splicing plate 16 can be connected to the adjacent splicing plate 16, so that the number of splicing plates 16 can be selected according to the distance between the front baffle 3 and the rear baffle 5, so as to better block and protect the side of the material, effectively preventing the material from moving and falling, with strong flexibility to meet the use requirements.

[0053] In this embodiment, preferably, please refer to Figure 3 and Figure 6 The carrier plate 2 is further provided with a slide rail 19, and the bottom of the rear baffle 5 is provided with a slide seat 20 that is slidably adapted to the slide rail 19. When the rear baffle 5 is moved along the guide rod 4, the bottom of the rear baffle 5 will also slide along the slide rail 19 through the slide seat 20, which not only provides support for the rear baffle 5 and reduces the bearing force of the guide rod 4, but also improves the smoothness of the movement of the rear baffle 5.
