DETAILED DESCRIPTION

[0025] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0027] This embodiment provides Figures 1 to 4 A hazardous chemical production safety transfer device shown includes a transfer forklift 1 for transferring hazardous chemicals in a production workshop. The transfer forklift 1 serves as a mobile platform for the entire device and is responsible for transferring chemical barrels 7 from one location to another. It provides the necessary power and control to ensure the safe transportation of goods. The chemical barrels 7 are the objects to be processed by this device and are used to store hazardous chemicals, such as gasoline. A transfer pallet 4 is placed on the floor of the production workshop, and chemical barrels 7 for carrying gasoline are stacked on the top surface of the transfer pallet 4. The front side of the transfer forklift 1 has two transfer fork rods 3 that can be raised and lowered and forked to the transfer pallet 4. The front side of the transfer forklift 1 has an inverted U-shaped transfer frame 5. Two hinged ear plates 11 are symmetrically welded to the outer walls of both sides of the U-shaped transfer frame 5. A foldable and retractable clamping and stabilizing mechanism 8 is hinged between the two adjacent hinged ear plates 11. When needed, it can be unfolded and tightened to hold the chemical barrel 7 to prevent it from shaking or tipping over during transportation. The foldable, retractable clamping and stabilizing mechanism 8 comprises an L-shaped side guard 9 hinged between two hinged lugs 11 via a pin, a servo motor 12 fixed to the outer wall of one of the hinged lugs 11, and a clamping inner plate 13 telescopically mounted on the inner wall of the L-shaped side guard 9. The output shaft of the servo motor 12 drives the L-shaped side guard 9 to flip, fold, and unfold vertically. The L-shaped side guard 9 forms part of the clamping structure and, working together with the clamping inner plate 13, forms a stable frame to surround and protect the chemical drum 7. The inner walls of both clamping inner plates 13 are equipped with elastic buffer fasteners. These elastic buffer fasteners resiliently clamp to the outer wall of the chemical drum 7 and fill the outer gap between adjacent chemical drums 7, providing a cushioning effect. The transfer forklift 1 has wheels 2 at its base, and the outer wall of the U-shaped transfer frame 5 is equipped with lifting guide rails 6 for the transfer fork 3 to raise and lower. The servo motor 12 drives the flipping of the L-shaped side guard 9, enabling the automated deployment and retraction of the clamping structure.

[0028] In this embodiment, a cylinder 16 is mounted in the middle of the inner wall of each L-shaped side guard plate 9. The free end of the piston rod of each cylinder 16 is bolted to the back of the adjacent clamping inner plate 13. Cylinder 16 controls the expansion and contraction of the clamping inner plate 13, allowing it to accommodate chemical drums 7 of varying sizes.

[0029] In this embodiment, two positioning rods 17 are symmetrically welded on either side of the cylinder 16 and on the back side of the clamping inner plate 13. The positioning rods 17 extend to the outside of the L-side guard plate 9 to facilitate the telescopic movement and positioning of the clamping inner plate 13. The positioning rods 17 keep the clamping inner plate 13 in the correct position for sliding, ensuring smooth operation.

[0030] In this embodiment, the elastic buffer fasteners include a silicone cushion 14 bonded to the inner wall of each clamping inner plate 13 and a first silicone filler cone 15 integrally connected to the center of the inner wall of the silicone cushion 14. The clamping inner plates 13 directly contact and secure the chemical drum 7. The silicone cushion 14 and first silicone filler cone 15 provide additional impact protection. The silicone cushion 14 provides a soft contact surface, reducing hard contact between the clamping inner plates 13 and the chemical drum 7, preventing damage to the drum.

[0031] In this embodiment, when the silicone cushion 14 is clamped against the outer wall of the chemical barrel 7, the first filling silicone cone 15 is inserted into the outer gap between two adjacent chemical barrels 7. The first filling silicone cone 15 is designed to adapt to the gap between the chemical barrels 7, increasing friction and providing a tighter fit, thereby improving overall stability.

[0032] In this embodiment, both sides of the outer wall of the first filling silica gel cone 15 are in an arc-shaped structure and are consistent with the peripheral outer wall of the chemical container 7 .

[0033] In this embodiment, removable end plates 10 are detachably mounted on the free ends of the two L-shaped side guard plates 9, away from the U-shaped transfer frame 5. A snap connector 18 is welded to the free end of each L-shaped side guard plate 9, and both ends of the removable end plates 10 are provided with snap-in holes 21 for receiving the snap connectors 18. The removable end plates 10 are located at one end of the L-shaped side guard plates 9 and serve to seal the opening of the clamping structure, further enhancing the safety and stability of the chemical container 7.

[0034] In this embodiment, locking holes 22 are provided on the outer walls on both sides of the detachable end plate 10, and the locking holes 22 pass through the adjacent snap-in holes 21. When the snap-in joint 18 is inserted into the snap-in hole 21, the snap-in joint 18 is locked in the snap-in hole 21 by the locking pin shaft 19 on both sides of the detachable end plate 10 through the locking hole 22.

[0035] In this embodiment, a second silicone filler cone 20 is bonded to the inner wall of the removable end plate 10. This second silicone filler cone 20 is inserted into and fills the gap between two adjacent chemical barrels 7 on the side away from the transfer forklift 1. The removable end plate 10 is in close contact with the outer walls of the two chemical barrels 7. Located on the inner side of the removable end plate 10, the second silicone filler cone 20 functions similarly to the first silicone filler cone 15, filling the gap between the chemical barrels 7 near the end plate to enhance safety.

[0036] Working principle:

[0037] Before starting the operation of this hazardous chemical production and transfer device, ensure that the transfer forklift 1 is in good working condition and all components such as the wheels 2, transfer fork rod 3, U-shaped transfer frame 5, and foldable and retractable clamping and stabilizing mechanism 8 are intact. Place the chemical barrel 7 on the transfer pallet 4. The transfer pallet 4 is designed to stably carry the chemical barrel 7 and avoid direct contact with the ground. Use the transfer fork rod 3 to insert it under the transfer pallet 4. The servo motor 12 drives the L-side guard plate 9 from the folded state to the vertical position, preparing to clamp the chemical barrel 7. The cylinder component 16 controls the clamping inner plate 13 to extend toward the chemical barrel 7. The silicone cushion pad 14 and the first filling silicone cone 15 inside the clamping inner plate 13 will contact the outer wall of the chemical barrel 7, providing a soft and tight clamping force, while filling the gap between adjacent barrels and reducing shaking. The positioning rod 17 ensures that the clamping inner plate 13 moves on the correct track and maintains its stability in the desired position. At this point, the chemical barrels 7 are securely fixed to the transfer pallet 4. The snap-fit ​​holes 21 of the detachable end plate 10 are plugged into the snap-fit ​​joints 18 of the transfer fork 3. The locking pin 19 passes through the locking hole 22 to lock the snap-fit ​​joints 18 in the snap-fit ​​holes 21. The second filling silicone cone 20 is inserted into and fills the gap between the two adjacent chemical barrels 7 on the side away from the transfer forklift 1. The detachable end plate 10 is used to close the opening of the clamping structure, further enhancing the safety and stability of the chemical barrels 7.

[0038] The entire load is then smoothly raised to the appropriate height via lifting rails 6. The transfer forklift 1 is activated, and the chemical barrel 7 is safely transported to the designated location using wheels 2. During this process, the chemical barrel 7 remains stable thanks to the clamping and stabilizing mechanism, reducing risks during transportation.

[0039] Upon arrival at the destination, the transfer fork 3 is lowered via the lifting guide rail 6, allowing the transfer pallet 4 to rest smoothly on the ground. The removable end plate 10 is then removed by removing the locking pin 19, disengaging the engaging hole 21 from the engaging joint 18. The hydraulic cylinder 16 controls the inner clamping plate 13 to retract away from the chemical drum 7, freeing it from the drum.

[0040] Finally, the L side guard plate 9 is driven by the servo motor 12 to return to the folded state to save space and facilitate next use.
