Description

Technical Field

[0001] This utility model relates to the field of steel drums, specifically a steel drum structure with a reinforced bottom. Background Technology

[0002] High wear-resistant steel drums are metal containers specifically designed to withstand extreme friction and impact conditions. They are reinforced with special materials and structures to extend their service life. Structurally, they often employ a seamless, one-piece molding process to prevent wear and cracking at joints. These steel drums are particularly suitable for applications such as ore transportation in mines, fly ash transport in thermal power plants, and aggregate turnover in construction.

[0003] For example, patent announcement number CN214877013U discloses a high wear-resistant steel drum, including an upper drum plate, an outer drum body, a friction plate, a base, and an inner drum body. The upper drum plate has a discharge port connected to its upper surface, and a drum cover is provided above the discharge port. The outer side of the drum cover has anti-slip textures. The inner drum body is located inside the outer drum body, and the upper drum plate is fixedly connected to its upper surface. One end of an elastic rubber block is fixedly connected to the outer side of the outer drum body, and the other end of the elastic rubber block is fixedly connected to an anti-collision plate. This high wear-resistant steel drum, equipped with the elastic rubber block and anti-collision plate, ensures that during use, if the drum is impacted by another object, it first impacts the anti-collision plate, and the impact force is reduced by the elastic rubber block before finally acting on the outer drum body. This prevents the external force from directly colliding with the inner drum body, thus avoiding the drum tipping over or deforming, or even causing deformation or spillage of the internal materials inside the drum.

[0004] Existing steel drums mostly have flat or simple curved bottoms, which are prone to deformation when subjected to internal high pressure or external stacking. At the same time, the bottom is not equipped with a protective structure, making it easy to be damaged when the bottom is impacted. Therefore, the market urgently needs to develop a steel drum structure with a reinforced bottom to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a steel barrel structure with a reinforced bottom, in order to solve the problems mentioned in the background art that the bottom of existing steel barrels is mostly flat or simple arc-shaped, which is easy to deform when subjected to internal high pressure or external stacking, and at the same time, the bottom does not have a protective structure, which makes the bottom of the barrel easily damaged when impacted.

[0010] Preferably, a connecting plate is fixedly connected to the upper end of the damping telescopic rod, and the connecting plate is fixedly connected to the circular support plate by a plurality of second bolts.

[0011] Preferably, the lower end of the telescopic end of the damping telescopic rod is fixedly connected to a bonding plate, and the lower end surface of the bonding plate is bonded to the upper end surface of the protective base plate.

[0014] (2) In this utility model, the buffer system composed of a protective bottom plate, a damping telescopic rod and a buffer spring can effectively absorb external impact force, reduce direct damage to the bottom structure of the barrel, and extend the service life of the steel barrel.

[0015] (3) In this utility model, a rigid connection design of annular support base plate and support column is adopted to ensure the stability of steel drums during stacking and transportation, while facilitating disassembly and maintenance, thus improving the practicality and applicability of steel drums.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a steel drum structure with a reinforced bottom, comprising a steel drum 1. A spherical bottom plate 101 is fixedly connected to the lower end of the interior of the steel drum 1. A circular support plate 102 is fixedly connected to the middle of the lower end of the spherical bottom plate 101. A support ring 103 is fixedly connected to the inner wall of the steel drum 1 at the lower edge of the spherical bottom plate 101. Multiple arc-shaped support rods 104 are fixedly connected in a ring array between the outer end face of the circular support plate 102 and the upper end face of the support ring 103. The upper end face of each arc-shaped support rod 104 is in contact with the lower end face of the spherical bottom plate 101. When the material inside the steel drum 1 generates pressure, the arched structure of the spherical bottom plate 101 can effectively disperse the pressure. At the same time, the pressure is transmitted to the support ring 103 and the side wall of the steel drum 1 through the multiple arc-shaped support rods 104, forming a multi-point support system, which significantly improves the pressure resistance of the bottom of the drum.

[0020] Please see Figure 2 and Figure 3The lower end of the steel drum 1 is connected to an annular support base plate 2. Multiple support columns 105 are fixedly connected to the lower end face of the support ring 103 in an annular array. Multiple limiting tubes 201 are fixedly connected to the upper end face of the annular support base plate 2 in an annular array. The lower ends of the multiple support columns 105 are respectively inserted into the multiple limiting tubes 201. The support columns 105 and the limiting tubes 201 are fixedly connected by the first bolts 202. Under the condition of stacking and transportation, the annular support base plate 2 and the spherical crown-shaped base plate 101 of the upper steel drum form a nested pressure-bearing structure. The rigid connection between the support columns 105 and the limiting tubes 201 ensures that the pressure is transmitted in the vertical direction, avoiding lateral deformation of the bottom structure of the drum. At the same time, by disassembling the multiple first bolts 202, the annular support base plate 2 can be separated from the steel drum 1 for easy maintenance and replacement.

[0021] Please see Figure 3 and Figure 4 A protective base plate 3 is installed between the lower end of the steel drum 1 and the upper end of the annular support base plate 2. A damping telescopic rod 4 is installed between the middle of the upper end of the protective base plate 3 and the lower end of the circular support plate 102. Multiple guide holes 301 are arranged in annular array on the protective base plate 3. The middle parts of multiple support columns 105 pass through the multiple guide holes 301 on the protective base plate 3, so that the protective base plate 3 can rise and fall between the upper end of the annular support base plate 2 and the lower end of the spherical base plate 101. A connecting plate 401 is fixedly connected to the upper end of the damping telescopic rod 4. The connecting plate 401 is fixedly connected to the circular support plate 102 by multiple second bolts 402. A bonding plate 403 is fixedly connected to the lower end of the telescopic end of the damping telescopic rod 4. The lower end surface of the bonding plate 403 is bonded to the upper end surface of the protective base plate 3. A buffer spring 404 is provided on the damping telescopic rod 4 and between the lower end of the connecting plate 401 and the upper end of the bonding plate 403. The damping telescopic rod 4 and the buffer spring 404 push the bonding plate 403 down to press down the protective bottom plate 3. When the steel barrel 1 is subjected to external impact, the protective bottom plate 3 first bears the impact force and moves upward along the support column 105 through the guide hole 301. At this time, the damping telescopic rod 4 and the buffer spring 404 are compressed synchronously. The impact energy is absorbed by the elastic deformation of the buffer spring 404. The gradual buffering is achieved in conjunction with the hydraulic damping effect of the damping telescopic rod 4. Finally, the residual force after attenuation is transmitted to the reinforced spherical bottom plate 101 structure through the circular support plate 102, which effectively prevents the spherical bottom plate 101 from deforming due to external impact.

[0022] Working principle: During use, when the material inside the steel drum 1 generates pressure, the arched structure of the spherical bottom plate 101 effectively disperses the pressure. Simultaneously, multiple arc-shaped support rods 104 transmit the pressure to the support ring 103 and the side wall of the steel drum 1, forming a multi-point support system that significantly improves the pressure resistance of the drum bottom. When the steel drum 1 is subjected to external impact, the protective bottom plate 3 first bears the impact force and displaces upward along the support column 105 through the guide hole 301. At this time, the damping telescopic rod 4 and the buffer spring 404 compress synchronously. The elastic deformation of the buffer spring 404 absorbs the impact energy, and the hydraulic damping effect of the damping telescopic rod 4 achieves gradual buffering. Finally, the attenuated residual force is transmitted to the reinforced spherical bottom plate 101 structure through the circular support plate 102. In stacked transportation conditions, the annular support base plate 2 and the spherical base plate 101 of the upper steel drum form a nested pressure-bearing structure. The rigid connection between the support column 105 and the limiting tube 201 ensures that the pressure is transmitted in the vertical direction, avoiding lateral deformation of the drum bottom structure.
