Description

Technical Field

[0001] The present invention relates to the technical field of plate transportation, and in particular to a shuttle bus used for plate transportation. Background Art

[0002] The plate transport shuttle is an automated device that can autonomously travel along a specific path or track and is used to transport plates between production lines, warehouses or different work areas. It is efficient, flexible, and intelligent, and can significantly improve the efficiency and accuracy of plate transportation. Compared with traditional manual handling or forklift transportation, the plate transport shuttle can achieve continuous and rapid plate transportation, greatly improving production efficiency. At the same time, it can also be linked with other production equipment to form an automated production line to further improve overall efficiency.

[0003] After searching, the Chinese patent with announcement number CN214987927U discloses a plate ferry vehicle, including a ferry vehicle body, wherein the lower left end of the ferry vehicle body is symmetrically connected to two front wheels, the lower right end of the ferry vehicle body is symmetrically connected to two rear wheels, the upper left end of the ferry vehicle body is connected to a cab, a driver's seat and a steering wheel are arranged in the cab, and the steering wheel is located on the left side of the driver's seat, and a storage bin is connected to the upper right end of the ferry vehicle body, and an iron plate is arranged at the inner bottom end of the storage bin. The utility model arranges a plurality of rollers, rotating shafts and bearings, and utilizes the mutual cooperation between them, so that the plates can be easily pushed into the storage bin, which is convenient for storing the plates and saves effort. Secondly, by arranging protective iron mesh plates, bolt holes and lock hook chains, more plates can be stored, which speeds up the speed of ferrying the plates, improves work efficiency, and the plates are fixed more firmly during the transportation process. However, the above scheme still has the following shortcomings when it is actually used:

[0004] In warehousing operations, shuttle buses are often used for material transportation tasks. However, material handling in warehouses does not only rely on shuttle buses. Forklifts and other handling equipment also play an important role. The design feature of forklifts is that their cargo is loaded at the front end. When the cargo is piled too high, it will seriously obstruct the driver's line of sight, making it difficult for the driver to accurately judge the surrounding environment, increasing operational risks. Especially in warehouses with limited space and frequent cross-operation of equipment, forklift drivers with obstructed vision may accidentally hit the shuttle bus. This collision may not only damage the shuttle bus itself, but also the materials carried on the shuttle bus, thereby affecting the overall operational efficiency and material safety of the warehouse.

[0005] Therefore, it is necessary to design a ferry vehicle for plate transportation to solve the above problems. Summary of the invention

[0053] The present invention has the following beneficial effects:

[0054] 1. By setting up the anti-collision component and the warning component, when the anti-collision roller is hit by the outside, the first thing that contacts the buffer plate is the direct impact force of the impact object. The buffer plate initially absorbs part of the energy through the elasticity and toughness of its material. Then, the movement of the buffer plate further compresses the buffer spring behind it. The compression process of the spring converts more kinetic energy into elastic potential energy, thereby significantly reducing the impact force transmitted to the frame. When the buffer oil filled in the buffer airbag package is compressed, it not only further disperses and absorbs the impact energy through the flow and compression of the oil, but also provides additional buffer space due to its compressibility, so that the entire anti-collision system can cope with a wider range of impact forces, effectively protecting the frame and the transported goods from damage. At the same time, when the anti-collision roller is hit and rotated, through the transmission action of the connecting rod, the knocking rod and the knocking head will knock on several alarm bells on the bottom of the mounting frame in turn, so that the alarm bells can emit continuous and loud warning sounds, quickly attracting the attention of surrounding staff, thereby avoiding further expansion of the accident and increase in losses;

[0055] 2. By setting a pushing component, when the cushioning airbag package is subjected to sufficiently large pressure, the cushioning oil inside it quickly flows to the two connecting airbag packages through the connecting pipe, the conduit, the main pipe and the connecting pipe. In this process, the flow of oil not only realizes the energy transfer, but also makes the connecting airbag package expand rapidly, generating sufficient thrust to drive the transport plate to slide on the bracket, ensuring that at the moment of impact, the transport plate and the goods on it can quickly move away from the collision point, thereby avoiding damage caused by direct impact;

[0056] 3. By setting the transport plate and the locking assembly, when the transport plate slides during a collision, the cooperation between the one-way tooth plate and the one-way tooth groove constitutes a reliable locking mechanism, so that the transport plate can slide smoothly along the guide port and the guide block when pushed by an external force, but when there is no external force or the external force is in the opposite direction, it will be stuck by the one-way tooth groove and cannot slide in the opposite direction. This not only enhances the stability during transportation, but also prevents the transport plate from suddenly retreating or shaking due to unexpected situations, thereby ensuring the safe transportation of goods.

Under the action of the inclined surface at the end of the one-way tooth plate 113, it can slide downward along the guide frame 112, so that the one-way tooth plate 113 is separated from the one-way tooth groove 114, and the limit of the transport plate 4 is released. At this time, the transport plate 4 can be pushed to reset it so that the shuttle bus can continue to be put into use. After the transport plate 4 is reset, the pull button 12 can be released, and under the action of the reset spring 117, the wedge block 116 can slide in the opposite direction to lift the one-way tooth plate 113 so that it enters the one-way tooth groove 114.

[0072] The specific working principle of the present invention is as follows:

[0073] First, the frame 1 can travel on the ground rail to transport materials. When the frame 1 is aligned with the transport port, the driving guide roller 6 on the transport plate 4 can be opened to load and unload materials on the transport plate 4. During the whole process, the control box 10 can control the shuttle bus, and the warning light 13 can warn the surrounding area to remind the surrounding staff. If the shuttle bus is hit by the outside world during the movement, since one side of the shuttle bus is in a position connected to the transport port, the collision will occur on the other side. During the collision, the foreign object can first contact the buffer plate 77 on the anti-collision roller 74 and squeeze the buffer plate 77. When the buffer plate 77 moves, the buffer spring 76 can be compressed to relieve the impact force. In addition, the anti-collision roller 74 can rotate during the collision to guide the impact object to prevent it from directly hitting the frame 1. When the buffer plate 77 moves, the buffer airbag bag 75 on the anti-collision roller 74 can be compressed, and then the buffer oil in the buffer airbag bag 75 can be used for buffering again, thereby fully reducing the damage to the frame 1 and the goods.

[0074] When the buffer airbag package 75 is impacted and compressed, the buffer oil inside it can enter the conduit 92 through the connecting pipe 93, and enter the two connecting airbag packages 91 through the main pipe 95 and the connecting pipe 96, so that the two connecting airbag packages 91 are filled and expanded. When the connecting airbag package 91 expands, it can drive the transport board 4, so that the transport board 4 slides on the bracket 2 through the guide port 3 and the guide block 5, thereby making the transport board 4 and the cargo thereon stay away from the anti-collision frame 71, further protecting the cargo on the shuttle bus;

[0075] During the sliding of the transport plate 4, the reverse direction is the free state of the one-way tooth plate 113 and the one-way tooth groove 114, so the transport plate 4 can slide directly and cannot slide in the reverse direction. After the collision, the staff can pull the pull button 12 to drive the wedge block 116 to move through the pull rod 115. Under the action of the inclined surface at the end of the one-way tooth plate 113, it can slide downward along the guide frame 112, so that the one-way tooth plate 113 is separated from the one-way tooth groove 114, and the limit of the transport plate 4 is released. At this time, the transport plate 4 can be pushed to reset it so that the shuttle bus can continue to be put into use. After the transport plate 4 is reset, the pull button 12 can be released. Under the action of the reset spring 117, the wedge block 116 can slide in the reverse direction to lift the one-way tooth plate 113 to make it enter the one-way tooth groove 114;

[0076] When the anti-collision roller 74 is hit and rotates, it can drive the connecting rod 81 to rotate synchronously. When the connecting rod 81 rotates, the two knocking rods 82 and the knocking head 83 thereon can rotate, so that the multiple alarm bells 84 on the bottom surface of the mounting frame 73 can be knocked one by one, so that the alarm bells 84 can emit a warning sound to remind the staff, making it convenient for the staff to discover the situation and deal with it in time.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
