Description

Technical Field

[0001] The present invention relates to the technical field of logistics containers, in particular to a high-buffered explosion-proof logistics ton barrel. Background Art

[0002] Ton barrels are essential tools for modern storage and transportation of liquid products, and are widely used in industries such as chemicals, pharmaceuticals, food, coatings, and oils. Ton barrels consist of a container and a metal frame. To ensure the support strength of the transfer base, existing technologies often use a steel support base fixed to the bottom of the metal frame to facilitate transfer and storage of the barrels in vertical warehouses. However, conventional ton barrels currently have the following problems: 1. When traditional ton barrels vibrate or fall during transportation, the inner container contacts the steel support base, and the energy is absorbed only by the elasticity of the material, which cannot effectively disperse the instantaneous impact force, causing stress cracks in the barrel body. 2. The existing metal frame and base are often fixed by welding or bolts or other detachable methods. The welded joints or bolted joints are prone to become the starting point of cracking under long-term cyclic loads, which can easily cause the ton barrel to fall off, posing a major safety hazard.

DETAILED DESCRIPTION

[0016] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0017] like Figure 1 、 Figure 2 and Figure 3 A high-buffered, explosion-proof logistics ton barrel includes a pallet base 100, an inner container 200 and an outer frame 300; a filling port 210 is provided on the top of the inner container 200, and a discharge port 220 is provided on the lower side of the inner container 200. A valve is provided on the discharge port to control whether the liquid is discharged.

[0018] The four corner edges of the upper surface of the pallet base 100 are provided with stoppers 110, and the middle part of the upper surface of the pallet base 100 is provided with a raised support seat 120. The support seat 120 is arranged concentrically with the pallet base 100. The thickness of the pallet base 100 is increased by the stepped pallet base 100 to ensure the supporting strength of the pallet base 100. The support seat 120 is provided with a strip channel 121 running through the left and right sides of the support seat, and the lower surface of the pallet base 100 is provided with a support foot 130; through the support foot 130, it is convenient to transfer by a forklift when stored in a vertical warehouse, which facilitates logistics transportation and optimizes logistics efficiency.

[0019] The side of the inner container 200 is provided with a plurality of vertical grooves 230, and the top of the inner container 200 is provided with a buffer protrusion 240; the vertical grooves 230 ensure the strength of the inner container 200 to avoid bursting, and ensure that the inner container 200 is subjected to force impact and can be released to the inside of the inner container 200 to buffer the force. This design can effectively absorb and disperse instantaneous loads, prevent the inner container from cracking or bursting, and extend the service life of the ton barrel.

[0020] The outer frame 300 is composed of a plurality of steel pipes staggered in a horizontal and vertical direction, which ensures that the outer frame 300 is stable and not easily deformed. When subjected to impact, the outer frame 300 protects the inner container 200 and reduces damage to the inner container 200.

[0021] The inner container 200 is placed on the support base 120, and the outer frame 300 is sleeved on the outside of the inner container 200. The bottom of the outer frame 300 is sleeved on the outside of the support base 120. The stoppers 110 contact the four corners of the bottom of the outer frame 300. The first steel tube 400 is inserted into the strip channel 121. The two ends of the first steel tube 400 are exposed from the strip channel 121. The two ends of the first steel tube 400 press against the bottom of the outer frame 300 to restrict and fix the outer frame 300. The use of the first steel tube 400 first ensures the support strength of the tray base 100, preventing the tray base from breaking when supported by force, causing the inner container to rupture and the solution to leak out. At the same time, the cooperation between the first steel tube 400, the support base 120, and the stoppers 110 also restricts the movement of the outer frame 300, fixing the outer frame 300 to the tray base, making it firmly fixed and more convenient to install, replacing traditional welding or bolting. This fixing method eliminates weak points such as welds or bolt holes, and is less likely to produce crack starting points under long-term cyclic loads, greatly improving structural stability, preventing the barrel from falling off, and enhancing safety.

[0022] Furthermore, the outer frame 300 includes a vertical rod 310, a first frame 320 and a second frame 330. The upper and lower ends of the vertical rod 310 are respectively connected to two parallel first frames 310. The second frame 320 is sleeved and fixed on the outside of the vertical rod 310. The second frame 330 is parallel to the first frame 320. The first frame 320 and the vertical rod 310 form the overall shape of the outer frame 300, which is further connected by the second frame 330 to ensure the stability of the overall structure of the outer frame 300, avoid breakage of the vertical rod, and avoid deformation. An upper rod 340 is also provided, the ends of which are respectively connected to the upper portions of two opposite vertical rods 310 on the left and right sides of the outer frame 300. The upper rod 340 is located above the inner container 200. A lifting lug is also provided above the inner container 200. The upper rod 340 passes through the lifting lug, confining the inner container 200 within the outer frame 300 and preventing it from rotating. The first steel tube 400 presses against the first frame 320 at the bottom of the outer frame 300. This ensures that the inner container 200 is located inside the outer frame 300 and prevents direct contact with foreign objects.

[0023] Furthermore, the number of the vertical rods 310 is the same as the number of the vertical grooves 230, and the vertical rods 310 are embedded in the vertical grooves 230. This limits the shaking and displacement of the inner container during transportation, reduces the collision and wear between the barrel body and the outer frame, and avoids the weakening of the wear area, resulting in reduced strength and cracks.

[0024] Furthermore, the first frame 320 and the second frame 330 are closed rectangular frames with rounded corners. The corresponding inwardly facing corners of the stopper 110 ensure that the inner side of the stopper 110 mates with the corners of the first frame 320 at the bottom, preventing displacement of the first frame 320. The rounded corner design avoids stress concentration at right angles, ensuring the strength of the first frame 320 and the second frame 330. At the same time, the corners of the inner container 200 are all rounded, and the rounded corners of the outer frame 300 mate with the inner container, resulting in an aesthetically pleasing structure and extending the life of the outer frame 300 against cyclic loads, ensuring the long-term use of the device.

[0025] Furthermore, the buffer protrusion 240 is formed by the outward protrusion of the side wall of the inner container, which ensures the volume of the inner container 200, ensures the volume requirement of the inner container 200, and also ensures the strength of the side wall of the inner container 200. The buffer protrusion 240 includes a square platform protrusion 241 and a strip protrusion 242. The strip protrusion 242 is arranged in the middle of the inner container 200. The strip protrusion 242 is arranged in the left and right directions to ensure the lateral strength of the upper surface of the inner container 200, avoid deformation of the inner container 200, enhance the top rigidity, and resist the upward impact force generated by the shaking of the internal liquid. There are four square platform protrusions 241, and the four square platform protrusions 241 are respectively close to the four corners of the upper surface of the inner container 200. An impact dispersion grid is formed to ensure that when the inner container 200 is impacted, the impact can be released inward, ensuring the strength and buffering force of the inner container 200, extending the service life of the inner container 200, and avoiding the inner container from bursting.

[0026] Furthermore, a nameplate 500 is fixed to the outer frame 300. The nameplate design facilitates information management and is used to identify the solution information in the barrel, etc., to facilitate product information traceability and management, facilitate logistics management, and achieve efficient logistics turnover.

[0027] Furthermore, the pallet base 100 is made of an integrated plastic material to ensure that the pallet base 100 has no seams and the strength of the pallet base 100 is ensured. The plastic pallet base 100 is lightweight and can provide a certain cushioning force, reducing the impact of the bottom pallet on the inner container 200 and preventing the inner container 200 from bursting. The inner container 200 is blow-molded in one piece to ensure that the inner container has no seams and high sealing performance, eliminating stress cracking points, and ensuring the sealing safety of the inner container 200 under high-pressure liquid storage to prevent leakage of contents. The pallet base 100 and the inner container 200 can be made of HDPE material, which has stable chemical properties and strong corrosion resistance. It remains flexible at -40°C to avoid brittle cracking in cold environments. It is also suitable for cold chain logistics, has high impact resistance, and reduces the risk of bursting.

[0028] Furthermore, the first steel tube 400 is a square or I-shaped steel tube, with screw holes 122 located near the edge of the support base 120. The screw holes 122 extend through the upper and lower sides of the strip channel 121. The screw holes 122 are countersunk, allowing the tops of the bolts to be retracted within the screw holes 122, preventing the tops of the bolts from contacting the inner container 200 and causing wear. Through holes 410 are located on the upper and lower sides of the first steel tube 400, near both ends of the first steel tube 400. The distance between the two through holes 410 at each end of the first steel tube 400 is equal to the distance between the two screw holes 122 on the left and right sides of the support base 120. The length of the first steel tube 400 is shorter than the horizontal length of the tray base 100. Bolting secures the first steel tube 400 to the tray base 100, preventing the first steel tube 400 from sliding within the strip channel 121 and causing the outer frame 300 to fall off. At the same time, the length of the first steel pipe 400 is smaller than the length of the pallet base 100, so as to prevent the first steel pipe 400 from being exposed on the left and right sides of the pallet base 100, causing interference and affecting the appearance of the ton barrel.

[0029] Furthermore, the upper and lower surfaces of the first steel tube 400 are provided with reinforcing ribs 420, which are arranged along the length of the first steel tube 400. The cross-section of the reinforcing ribs 420 is semicircular, and there are two reinforcing ribs 420 on each side, respectively arranged at the two side edges of the first steel tube 400. The reinforcing ribs 420 are integrally connected to the first steel tube 400. This significantly improves the deformation resistance of the first steel tube 400. During use, the upper and lower surfaces with reinforcing ribs 420 are arranged in an up-down direction. When the first steel tube 400 is subjected to vertical force, the reinforcing ribs 420 increase the moment of inertia of the section and evenly transfer the load along the length, avoiding local buckling deformation, ensuring the strength of the reinforcing ribs 420, and preventing the reinforcing ribs 420 from breaking. The reinforcing ribs 420 have strong load-bearing capacity. The integrated reinforcing ribs 420 eliminate welding or splicing weaknesses, making fatigue cracks less likely to occur under long-term vibration loads, thereby extending the service life. The semicircular cross-section design enables the reinforcing rib 420 to produce controllable elastic deformation when under pressure, absorbing part of the impact energy, having high shock resistance, dispersing the impact energy of falling, reducing the impact amplitude transmitted to the inner container 200, and preventing the inner container 200 from cracking due to the impact.

[0030] Furthermore, the upper surface of the support base 120 is overmolded with a cushioning layer 123 made of TPE (5-10mm thick). The high surface friction of the cushioning layer 123 prevents the inner container 200 from moving on it, preventing the inner container 200 from swaying and shifting during transportation. This reduces wear and tear between the outer surface of the inner container 200 and the outer frame 300, minimizing the occurrence of weak points of wear and tear, and ensuring stable cushioning performance for the long-term use of the ton-barrel inner container 200. This ensures soft contact between the inner container 200 and the pallet base 100, providing elastic cushioning and increasing the impact absorption rate by over 30%, preventing the inner container 200 from bursting due to transient impacts caused by transportation vibration or drops.

[0031] The present invention has been described with reference to the above embodiments. However, the above embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements that do not depart from the spirit and scope of the present invention are intended to be protected by the present invention.
