Description

Technical Field

[0001] This utility model relates to the field of steel cylinder technology, and in particular to a high-strength welded steel cylinder. Background Technology

[0002] Gas cylinders are essential for storing liquefied gases and other chemical products. Currently, gas cylinders are manufactured using welded support rings at the bottom, resulting in relatively high production costs. The materials used for these support rings are also relatively expensive. The valves are operated manually, making intelligent operation inconvenient. Clamping the handle with tools can cause wear and tear, potentially leading to hand injuries. Existing cylinder handles are made by bending metal plates, resulting in relatively low load-bearing capacity. For heavier cylinders, the handle is prone to deformation and cannot be properly supported by a support frame. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength welded steel cylinder. By setting an integrated support structure at the bottom, it effectively saves on the material and production costs of the cylinder's bottom structure. The upper handle position uses a handle frame in conjunction with a reinforced support frame, which not only ensures safety when carrying the cylinder, but also allows the bottom of this position to be used with support plate components for overall placement of the cylinder, providing greater flexibility in overall placement. The top manual operation valve position is equipped with an intelligent matching structure, which can be connected to the intelligent control setting component as needed during use, effectively avoiding direct contact with the manual operation position and ensuring better safety of the manual operation position.

[0004] The technical solution of this utility model is as follows:

[0005] A high-strength welded steel cylinder includes a first cylinder main body structure and a second cylinder main body structure connected together by welding. The second cylinder main body structure has three circumferentially evenly distributed, downward-facing spherical support bosses integrally mounted on its lower end. The first cylinder main body structure has a cylinder interface assembly at its upper end. A reinforcing support plate with a T-shaped projection in the vertical direction is located at the connection point between the upper end of the first cylinder main body structure and the cylinder interface assembly. Handles inclined upwards and outwards are connected to the left and right sides of the reinforcing support plate by wrapping around it. The handle has a reinforced support frame welded to its lower ends on both the front and rear sides, which has a right-angled projection in the front-rear direction. The lower end of the reinforced support frame forms a stable support plane. The support boss is formed by mold pressing. An explosion-proof plate is provided on the upper rear side of the main body of the first cylinder. The cylinder interface assembly has a cylinder delivery port on its side. The upper end of the cylinder interface assembly has a manual operation valve seat. The upper end of the manual operation valve seat has an intelligent control connection column. The outer side of the intelligent control connection column has a fastening connection threaded groove.

[0006] Furthermore, the bottom of the supporting and fitting boss is provided with a stable fitting surface.

[0007] Furthermore, the width of the upper part of the handle frame is greater than the width of the lower part.

[0008] Furthermore, the distance between the left and right sides of the handle bracket is the same as the diameter of the main body structure of the first cylinder.

[0009] Furthermore, the intelligent control connecting column is detachably connected to the upper center position of the manual operation valve seat.

[0010] Furthermore, the cross-section of the carrying handle frame is circular.

[0011] The beneficial effects of this utility model are:

[0012] This invention effectively saves on material and production costs for the bottom structure of the gas cylinder by setting an integrated support structure at the bottom. The upper handle position uses a handle frame in conjunction with a reinforced support frame, which not only ensures safety when carrying the cylinder, but also allows the bottom of this position to be used with support plate components for overall placement of the gas cylinder, making the overall placement more flexible. The top manual operation valve position is equipped with an intelligent matching structure, which can be connected to the intelligent control setting component as needed during use, effectively avoiding direct contact with the manual operation position and ensuring better safety of the manual operation position.

[0021] like Figures 1 to 7As shown, a high-strength welded steel cylinder includes a first main cylinder structure 1 and a second main cylinder structure 2 connected together by welding. The lower end of the second main cylinder structure 2 is integrally equipped with three circumferentially distributed, downward-facing spherical support bosses 3, which serve as a support structure for the overall bottom during use. The upper end of the first main cylinder structure 1 is equipped with a cylinder interface assembly 4. At the connection point between the upper end of the first main cylinder structure 1 and the cylinder interface assembly 4, a reinforcing support plate 5 with a T-shaped projection in the vertical direction is provided, ensuring better structural stability at the top. The left and right sides of the reinforcing support plate 5 are respectively connected to a handle frame 10 inclined upwards and outwards by wrapping, allowing for hand-carrying operation. The lower ends of the front and rear sides of the handle frame 10 are respectively equipped with reinforcing support frames 11 with a right-angled projection in the front-rear direction, ensuring better structural strength. The lower end of the reinforced support frame 11 forms a stable support plane, which can be used with support rods or support plates as needed for support and placement, enabling the cylinder to be placed with top support and providing greater flexibility during placement. The support and placement boss 3 is processed by mold pressing, resulting in higher production efficiency and better structural stability. An explosion-proof plate 6 is provided on the upper rear side of the first cylinder main body structure 1, and a cylinder delivery port 7 is provided on the side of the cylinder interface assembly 4. The upper end of the cylinder interface assembly 4 is provided with a manual operation valve seat 8, which allows for manual opening and closing of the valve. The upper end of the manual operation valve seat 8 is provided with an intelligent control connection post 9. The external side of the intelligent control connection post 9 is provided with a fastening connection combination threaded groove, which can be used to connect with the intelligent opening and closing control component. This replaces the existing intelligent component that needs to be directly clamped to the hand position of the manual operation valve seat, avoiding wear on the hand position during clamping and ensuring better safety during hand operation. By incorporating an integrated support structure at the bottom, it effectively saves on material and production costs for the cylinder's bottom structure. The upper handle position uses a carrying handle frame in conjunction with a reinforced support frame, which not only ensures safety when carrying the cylinder but also allows for the overall placement of the cylinder with support plate components, providing greater flexibility in overall placement. The top manual operation valve position features an intelligent connection structure that allows it to connect with the intelligent control components as needed during use, effectively avoiding direct contact with the manual operation position and ensuring better safety for the manual operation position.

[0022] Preferably, the bottom of the support and placement boss 3 is provided with a stable placement surface, which makes the placement area larger and the placement stability better.

[0023] Preferably, the width of the upper part of the handle bracket 10 is greater than the width of the lower part, so that there is more space for carrying at the upper part and less space occupied at the lower side, which makes it more convenient to produce.

[0024] Preferably, the distance between the left and right sides of the handle bracket 10 is the same as the diameter of the first cylinder body structure 1, which makes the overall structure of the outer side more flat and further improves the safety during use.

[0025] Preferably, the intelligent control connecting column 9 is detachably connected to the upper center of the manual operation valve seat 8, which is more convenient during production and can be flexibly replaced as needed.

[0026] Preferably, the handle frame 10 has a circular cross-section, which provides better comfort when carrying it.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
