Description

Technical Field

[0001] This utility model relates to the technical field of cargo transportation equipment requiring fire and explosion protection, and in particular to a new type of pneumatic loading and unloading palletizing vehicle. Background Technology

[0002] With societal progress and business development, there is an increasing number of material handling operations requiring fire and explosion protection. Explosion protection methods generally include electric and pneumatic systems. The existing pneumatic transfer method utilizes pneumatic loading and unloading palletizing vehicles. These vehicles typically possess multiple functions such as handling, lifting, and palletizing, enabling them to complete the grabbing, handling, and stacking of goods in a single operation, reducing intermediate steps and improving overall loading and unloading efficiency.

[0003] However, the existing pneumatic palletizer lifting mechanism relies on an external connecting air hose to connect to the air compressor. The length of the air hose directly determines the range of motion of the palletizer. An excessively long air hose is prone to tangling and knotting, affecting the flexible movement and operation of the palletizer. On the other hand, an excessively short air hose limits the palletizer to working only in a certain area near the air compressor, which cannot meet the needs of a large-scale work site and reduces the flexibility of the equipment. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A novel pneumatic loading and unloading palletizing vehicle includes a palletizing vehicle body, which includes a gantry lifting frame. An installation assembly is fixedly installed on the bottom wall of the gantry lifting frame. The installation assembly includes a semi-circular fixing plate, a semi-circular ring fixing plate, an arc-shaped plate, a foam support pad, and a limiting cover assembly. The semi-circular fixing plate and the semi-circular ring fixing plate are both fixedly installed on the bottom wall surface of the gantry lifting frame. The arc-shaped plate is welded between the semi-circular fixing plate and the semi-circular ring fixing plate. The semi-circular fixing plate, the semi-circular ring fixing plate, and the arc-shaped plate, together with the gantry lifting frame, form a cavity with an opening on one side. The foam support pad is adhesively installed on the arc-shaped plate and the inner wall surface of the gantry lifting frame. A compressed air cylinder is movably installed between the foam support pads.

[0005] As an improvement to the above technical solution, a hinge seat is fixedly installed on one side of the upper surface of the semi-circular ring fixing plate, and the hinge seat is rotatably installed with the limiting cover assembly.

[0006] As an improvement to the above technical solution, the limiting cover assembly includes an arc-shaped cover plate and a U-shaped rotating seat. The U-shaped rotating seat is welded and installed on one side of the arc-shaped cover plate, and the U-shaped rotating seat is rotatably installed on both sides of the outer wall of the hinge seat. The arc-shaped cover plate is fitted and installed on the outside of the semi-circular ring fixing plate.

[0007] As an improvement to the above technical solution, the center of the arc-shaped cover plate is a hollow circle, and an annular clamping seat is welded and installed on the center surface of the arc-shaped cover plate. The annular side of the annular clamping seat is welded and installed to the U-shaped rotating seat, and the square side of the annular clamping seat is detachable.

[0008] As an improvement to the above technical solution, the side wall of the gantry lifting frame is provided with a fixing hole, and a fastening bolt is movably installed between the square side of the annular clamping seat and the fixing hole of the side wall of the gantry lifting frame. A fixing bolt is detachably installed between the square side of the annular clamping seat and the fixing hole of the side wall of the gantry lifting frame.

[0009] The beneficial effects of this utility model are: 1. This utility model installs an assembly on the gantry lifting frame of the palletizing cart. This assembly, through the synergistic action of a semi-circular fixing plate, a semi-circular ring fixing plate, and an arc-shaped plate, forms a stable structure for mounting compressed air cylinders. Combined with the cushioning of foam support pads and the limiting cover assembly, this effectively reduces the shaking and collision of the compressed air cylinders during the palletizing cart's operation, improving the overall structural stability of the equipment and lowering the failure rate. Using compressed air cylinders as a power source eliminates the limitation of traditional pneumatic palletizing carts relying on external connecting air pipes to air compressors. It eliminates the need for long air pipes, avoiding problems such as pipe tangling and knotting, allowing the palletizing cart to operate over a wider area. The free movement and operation enhance the equipment's flexibility and operational efficiency. The foam support pads effectively absorb vibration and impact, protecting the compressed gas cylinders from damage, extending their service life, and reducing operating costs. The stable installation structure also minimizes the impact of compressed gas cylinder movement on other components of the palletizing cart, further improving the overall reliability and durability of the equipment. The side-opening cavity design makes the installation and replacement of compressed gas cylinders more convenient and quick. Operators can complete the installation and maintenance of compressed gas cylinders without complicated tools and procedures, saving time and labor costs and improving the maintainability of the equipment.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Please see Figure 1-5 This utility model provides a technical solution: A novel pneumatic loading and unloading palletizing vehicle includes a palletizing vehicle body 1, which includes a gantry lifting frame 11. An installation assembly 2 is fixedly installed on the bottom wall of the gantry lifting frame 11. The installation assembly 2 includes a semi-circular fixing plate 21, a semi-circular ring fixing plate 22, an arc-shaped plate 23, a foam support pad 24, and a limiting cover assembly 25. The semi-circular fixing plate 21 and the semi-circular ring fixing plate 22 are both fixedly installed on the bottom wall surface of the gantry lifting frame 11. The arc-shaped plate 23 is welded between the semi-circular fixing plate 21 and the semi-circular ring fixing plate 22. The semi-circular fixing plate 21, the semi-circular ring fixing plate 22, and the arc-shaped plate 23 are installed with the gantry lifting frame 11 to form a cavity with an opening on one side. The foam support pad 24 is glued to the arc-shaped plate 23 and the inner wall surface of the gantry lifting frame 11. A compressed air cylinder 3 is movably installed between the foam support pads 24.

[0014] In this implementation scheme, the palletizing cart body 1 is the main frame of the entire equipment, providing the installation foundation and support structure for other components. Powered by compressed gas cylinders, it carries various functions such as handling, lifting, and palletizing of goods, serving as the core carrier for loading and unloading operations. The gantry lifting frame 11, as a key component of the palletizing cart body 1, provides a fixed position for the installation assembly 2. It possesses high strength and stability, capable of bearing the weight of the installation assembly 2 and the compressed gas cylinder 3, and provides necessary support and guidance during the lifting and lowering of goods, ensuring smooth and accurate lifting and lowering. The semi-circular fixing plate 21 of the installation assembly 2 is fixedly installed on the bottom wall surface of the gantry lifting frame 11, providing a stable fixing foundation for the entire installation assembly 2. Together with the semi-circular ring fixing plate 22 and the arc-shaped plate 23, it forms a specific structure for installing and fixing the compressed gas cylinder 3. The semi-circular ring fixing plate 22 is also fixedly installed on the bottom wall surface of the gantry lifting frame 11, working in conjunction with the semi-circular fixing plate 21. Through welding connection with the arc-shaped plate 23, they jointly construct a spatial structure to accommodate the compressed gas cylinder 3, enhancing the fixing effect of the compressed gas cylinder 3. The profile plate 23 is welded and installed between the semi-circular fixing plate 21 and the semi-circular ring fixing plate 22. Its arc-shaped structure is adapted to the shape of the compressed gas cylinder 3, which can better fit the compressed gas cylinder 3 and provide more stable support and fixation. It forms a cavity with one side opening when installed with the semi-circular fixing plate 21, the semi-circular ring fixing plate 22 and the gantry lifting frame 11, which facilitates the installation and removal of the compressed gas cylinder 3. The foam support pad 24 is glued to the inner wall surface of the arc-shaped plate 23 and the gantry lifting frame 11, which plays a role in buffering and shock absorption. It can effectively reduce the impact during the movement or operation of the palletizing vehicle. The compressed gas cylinder 3 is less prone to vibration and collision with the arc plate 23 and the gantry lifting frame 11, protecting the compressed gas cylinder 3 from damage and extending its service life. The limiting cover group 25 further limits and fixes the compressed gas cylinder 3 to prevent it from shaking or shifting in the cavity, ensuring the stability and safety of the compressed gas cylinder 3 installation. The compressed gas cylinder 3 is one of the power sources of the new loading and unloading palletizing vehicle, providing gas power for the lifting, handling and other operations of the palletizing vehicle. By releasing compressed gas, it drives the relevant pneumatic components to work, realizing the functions of grabbing, handling and stacking goods.

[0015] Workflow: Compressed gas cylinder 3 installation: Insert the compressed gas cylinder 3 into the side opening formed by the mounting component 2, so that the compressed gas cylinder 3 fits against the arc plate 23. The foam support pad 24 provides initial cushioning support for the compressed gas cylinder 3. Then, install the limiting cover assembly 25 to limit and fix the compressed gas cylinder 3, ensuring that the compressed gas cylinder 3 is installed stably. Operate the palletizing trolley body 1 to move it to the location of the goods. By controlling the relevant pneumatic control system, the gas provided by the compressed gas cylinder 3 is used to drive the palletizing trolley to support the goods. After the goods reach the target position, the lifting mechanism of the gantry lifting frame 11 is controlled by the gantry lifting frame 11. The power of the compressed gas cylinder 3 is used to lower the gantry lifting frame 11, accurately stacking the goods in the designated position. Then, release the gripping device to complete one loading, unloading and palletizing operation of the goods.

[0016] Beneficial effects: By installing the mounting component 2 on the gantry lifting frame 11 of the palletizer body 1, the mounting component 2, through the synergistic action of the semi-circular fixing plate 21, the semi-circular ring fixing plate 22, and the arc-shaped plate 23, forms a stable structure to install the compressed air cylinder 3. Combined with the cushioning of the foam support pad 24 and the limiting cover assembly 25, the shaking and collision of the compressed air cylinder 3 during the palletizer's operation are effectively reduced, improving the overall structural stability of the equipment and reducing the equipment failure rate. Using the compressed air cylinder 3 as a power source eliminates the limitation of traditional pneumatic palletizers relying on external connecting air pipes to connect to the air compressor, eliminating the need for long air pipes and avoiding problems such as air pipe tangling and knotting. This allows the palletizer to operate more efficiently. The wider range of movement and operation improves the equipment's flexibility and operational efficiency. The foam support pad 24 effectively absorbs vibration and impact, protecting the compressed gas cylinder 3 from damage and extending its service life, thus reducing the equipment's operating costs. The stable installation structure also reduces the impact of the compressed gas cylinder 3's shaking on other parts of the palletizing vehicle, further improving the overall reliability and durability of the equipment. The cavity design with an opening on one side makes the installation and replacement of the compressed gas cylinder 3 more convenient and quick. Operators can complete the installation and maintenance of the compressed gas cylinder 3 without complicated tools and operating procedures, saving time and labor costs and improving the equipment's maintainability.

[0017] Specifically, a hinge seat 221 is fixedly installed on one side of the upper surface of the semi-circular ring fixing plate 22, and the hinge seat 221 is rotatably installed with the limiting cover assembly 25.

[0018] In this embodiment, the hinge seat 221 provides a pivot point for the limiting cover assembly 25, allowing the limiting cover assembly 25 to rotate flexibly around the hinge seat 221. This makes opening and closing the limiting cover assembly 25 easy and convenient, eliminating the need for complex disassembly and installation processes. For example, when installing or replacing the compressed gas cylinder 3, simply rotate the limiting cover assembly 25 upwards around the hinge seat 221 to open it, providing sufficient installation space for the compressed gas cylinder 3. After installation, rotate the limiting cover assembly 25 downwards to close it, thus completing the limiting and fixing of the compressed gas cylinder 3. The hinge seat 221 and the limiting cover assembly 25 are connected by a pivot pin to achieve rotatable installation. This connection method ensures the stability of the limiting cover. During rotation, the connection between assembly 25 and hinge seat 221 is stable and reliable, and there will be no loosening or falling off. Even under frequent vibration and movement of the palletizing vehicle, the limiting cover assembly 25 can always remain in the correct position and perform its limiting function normally. When the limiting cover assembly 25 rotates around the hinge seat 221 and closes, it can form a closed or semi-closed space together with the semi-circular fixing plate 22, semi-circular fixing plate 21 and arc plate 23, which firmly fixes the compressed gas cylinder 3 in it. This limiting and fixing method can prevent the compressed gas cylinder 3 from shifting or falling off due to shaking, vibration or inertial force during the operation of the palletizing vehicle, thereby ensuring the safe use of the compressed gas cylinder 3.

[0019] Specifically, the limiting cover assembly 25 includes an arc-shaped cover plate 251 and a U-shaped rotating seat 252. The U-shaped rotating seat 252 is welded and installed on one side of the arc-shaped cover plate 251. The U-shaped rotating seat 252 is rotatably installed on both sides of the outer wall of the hinge seat 221. The arc-shaped cover plate 251 is closed and installed on the outside of the semi-circular ring fixing plate 22.

[0020] In this embodiment, the arc-shaped cover plate 251's arc design can closely fit the outer contour of the compressed gas cylinder 3. When the arc-shaped cover plate 251 is closed on the outside of the semi-circular ring fixing plate 22, it, together with the semi-circular fixing plate 21, arc-shaped plate 23, and other components, forms a semi-enclosed limiting space, firmly fixing the compressed gas cylinder 3 within it. This precise limiting can prevent the compressed gas cylinder 3 from shifting or falling off due to shaking, vibration, or inertial force during equipment operation, ensuring that the compressed gas cylinder 3 is always in a stable position and guaranteeing the safe operation of the equipment. The arc-shaped cover plate 251 is made of a material with a certain degree of elasticity or has a surface design. A buffer layer, such as a rubber pad, can further enhance the buffering effect and extend the service life of the compressed gas cylinder 3. The U-shaped rotating seat 252 is rotatably installed on both sides of the outer wall of the hinge seat 221, so that the arc-shaped cover plate 251 can rotate flexibly around the hinge seat 221. When it is necessary to install or replace the compressed gas cylinder 3, simply push the arc-shaped cover plate 251 gently to rotate it upward around the hinge seat 221 to open it, which can provide sufficient installation space for the compressed gas cylinder 3. After installation, the arc-shaped cover plate 251 is rotated downward to close it. The operation is simple and convenient, without complicated disassembly and installation processes, which greatly improves work efficiency.

[0021] Specifically, the center of the arc-shaped cover plate 251 is a hollow circle, and an annular clamping seat 253 is welded and installed on the central surface of the arc-shaped cover plate 251. The annular side of the annular clamping seat 253 is welded and installed to the U-shaped rotating seat 252, and the square side of the annular clamping seat 253 can be detached and installed.

[0022] In this embodiment, the circular cutout in the center of the arc-shaped cover 251 serves to provide operators with a direct observation window. During equipment operation, relevant parameters of the compressed gas cylinder 3, such as pressure gauge readings and liquid level indications, can be directly observed through this window without opening the arc-shaped cover 251. This is convenient and quick, allowing for timely monitoring of the working status of the compressed gas cylinder 3 and ensuring safe equipment operation. If the compressed gas cylinder 3 requires certain operations through its center, such as connecting pipes or sensors, the circular cutout provides the necessary space and passage for these operations, making the equipment layout more rational and its functions more complete. Welding one side of the annular clamping seat 253 to the U-shaped rotating seat 252 ensures that the two form a whole, withstanding greater external forces without separation or loosening. During equipment operation, the arc-shaped cover... 251 is subject to various forces, such as vibration of compressed gas cylinder 3 and external impact. This welding connection method can ensure the structural stability of the limiting cover assembly 25 and improve the safety and reliability of the equipment. The hollow circular part in the middle of the arc-shaped cover plate 251, the welding of the annular clamping seat 253 and the U-shaped rotating seat 252, and the detachable installation of the square side of the annular clamping seat 253, these structures work together to form a fully functional and reliable limiting cover assembly 25. The hollow circular part provides space for observation and operation, the welding of the annular clamping seat 253 and the U-shaped rotating seat 252 ensures the strength and stability of the structure, and the detachable installation method increases the flexibility and maintainability of the equipment. The overall synergistic effect enables the limiting cover assembly 25 to better meet the limiting, protection and operation requirements of compressed gas cylinder 3, and improve the safety and efficiency of the entire equipment.

[0023] Specifically, the side wall of the gantry lifting frame 11 has a fixing hole 111, and a fastening bolt 254 is movably installed between the square side of the annular clamping seat 253 and the fixing hole 111 on the side wall of the gantry lifting frame 11. A fixing bolt 255 is detachably installed between the square side of the annular clamping seat 253 and the fixing hole 111 on the side wall of the gantry lifting frame 11.

[0024] In this embodiment, the fixing hole 111 provides a precise positioning point for the connection between the annular clamping seat 253 and the gantry lifting frame 11. By pre-opening the fixing hole 111 on the side wall of the gantry lifting frame 11, it can be ensured that the annular clamping seat 253 can be accurately installed in the designated position, ensuring the relative position accuracy between the entire limiting cover assembly 25 and the gantry lifting frame 11, thereby making the limiting cover assembly 25's limiting and protection function for the compressed gas cylinder 3 more reliable.
