DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] Embodiment 1

[0031] Reference Figure 1-Figure 5 As shown, the utility model is a multifunctional working platform for a vertical fuel tank, comprising:

[0032] The base 1 is a rectangular frame structure, and four supporting parts 11 are symmetrically arranged on the inner wall of the base 1 and are parallel to the base 1;

[0033] The vertical poles 2 are four in number, and the four vertical poles 2 are respectively vertically connected to the supporting parts 11;

[0034] A supporting ring 3, the supporting ring 3 is vertically connected to one end of each upright 2 away from the base 1, and the supporting ring 3 is coaxial with the base 1;

[0035] The inclined rod group 4 is provided with four groups, and the four groups of inclined rod groups 4 correspond to a frame edge of the base 1 respectively. Each inclined rod group 4 includes two inclined rods 41, one end of the two inclined rods 41 is respectively connected to the two ends of the corresponding frame edge, and the other ends are close to each other and connected to the supporting ring 3. The two inclined rods 41 and the frame edge connected thereto form an isosceles triangle structure;

[0036] The workbench 5 is a ring-shaped structure. The workbench 5 is provided with multiple layers. The multiple layers of the workbench 5 are arranged at intervals along the length direction of the vertical pole 2 and are coaxial with the base 1 . The workbench 5 is connected to each vertical pole 2 and the inclined pole 41 .

[0037] Specifically, the base 1 is horizontally arranged, and the base 1 is a square frame structure welded from box-shaped steel. A support portion 11 is parallelly connected to the inner wall of the frame structure at positions corresponding to its four corners, and a triangular structure is formed between the support portion 11 and the frame edge of the base 1; each support portion 11 is vertically connected to a vertical pole 2, and the vertical pole 2 is located on the diagonal line of the base 1, and the end of the vertical pole 2 away from the base is vertically connected to the supporting ring 3; and four groups of inclined rod groups 4 corresponding to one frame edge of the base 1 are arranged between the supporting ring 3 and the base 1, and each inclined rod group 4 includes two inclined rods 41, one end of the two inclined rods 41 is respectively connected to the two ends of the corresponding frame edge, and the other ends are close to each other and connected to the supporting ring 3, and a plurality of symmetrically distributed triangular structures are formed between the adjacent inclined rods 41 and the base 1 or the supporting ring 3; a plurality of workbenches 5 are stacked and embedded between the vertical poles 2 and the inclined rods 41, and finally form this multifunctional working platform.

[0038] The vertical pole 2 is used as the main load-bearing pole, and the diagonal pole 41 is used as the secondary load-bearing pole to assist the vertical pole 2 to ensure the stability and strength of the entire structure. The workbench 5 is not only used as a platform for carrying workers, but also serves to connect the vertical pole 2 and the diagonal pole 41, further improving the strength and bearing capacity of the entire work platform. The structure of the entire multifunctional work platform is simple, which simplifies the difficulty and process of platform installation and construction, can reduce the time of platform construction, and has sufficient bearing capacity and structural stability.

[0039] Reference Figure 2 As shown, further, the support portion 11 is a T-shaped structure, including a first section and a second section vertically connected to the middle position thereof, the two ends of the first section are respectively connected to the inner walls of the two adjacent frame edges, and the free end of the second section is connected to the connection position of the two adjacent frame edges. Specifically, a connection position for connecting the upright pole 2 is provided in the middle position of the first section, which can facilitate the installation and positioning of the upright pole 2 and ensure the symmetry of the entire structure, which is beneficial to the stability and strength of the platform structure.

[0040] Reference Figure 1 , Figure 3 and Figure 4As shown, further, the supporting ring 3 includes an annular main body 31, and the two ends of the annular main body 31 are respectively connected in parallel with a first annular support plate 32 and a second annular support plate 33 coaxial therewith, and the inner edges of the first annular support plate 32 and the second annular support plate 33 extend into the inner hole of the annular main body 31, the inner diameter of the first annular support plate 32 is smaller than the inner diameter of the second annular support plate 33, and a plurality of ribs 34 arranged in a circumferential annular array are vertically arranged on the inner wall of the annular main body 31, and the two ends of the ribs 34 are respectively vertically connected to the first annular support plate 32 and the second annular support plate 33, and at the same time, a side of the ribs 34 away from the annular main body 31 is an inclined surface. Specifically, during the inspection and spraying process, the tank body is vertically connected to the multifunctional working platform, the tank body passes through the supporting ring 3, and the connecting ring on the circumferential surface of the tank body is connected to the first annular support plate 32, and the inner diameter of the second annular support plate 33 is larger than the inner diameter of the first annular support plate 32, so that there is a larger space between the inner side of the supporting ring 3 and the tank body compared with the straight surface structure (the inner wall of the structure of the connecting ring of the existing support frame used to support the tank body is a straight surface, and the space between the inner wall and the tank body is narrow, making the spraying operation difficult. After one spraying, the tank body needs to be lifted for a second spraying of those positions that have not been fully sprayed), which is convenient for the operator to perform the spraying operation and can achieve one-time spraying, which can reduce the spraying cost and time while improving the safety of the entire spraying process.

[0041] Furthermore, the ends of the vertical rod 2 and the diagonal rod 41 away from the base 1 are connected to the second annular support plate 33. Specifically, the inclined surfaces of the plurality of ribs 34 make the inner side of the support ring 3 close to the conical surface (i.e., have a certain slope), and the end with a larger diameter of the conical surface is close to the second annular support plate 33, so that there is a larger working space between the inner side of the support ring 3 and the tank body.

[0042] Reference Figure 1 As shown, further, each upright pole 2 is provided with a plurality of footrests 21 spaced apart along the length direction thereof, and each workbench 5 is provided with a manhole 51 corresponding to the position of the footrests 21. It can be imagined that the staff sprays the tank body layer by layer through the workbench 5, and when the work on one layer of the workbench 5 is completed, the staff can enter another layer through the footrest 21 for spraying.

[0043] Furthermore, each workbench 5 is provided with a guardrail 52 extending along the outer edge thereof to prevent workers from falling from the workbench and ensure the safety of the operation process.

[0044] Furthermore, the workbench 5 is an annular plate structure with flanged edges.

[0045] Furthermore, each workbench 5 is provided with a connection hole corresponding to the position of each vertical rod 2 and the diagonal rod 41 , and the vertical rod 2 and the diagonal rod 41 pass through the corresponding connection holes and are connected to the workbench 5 at the connection holes.

[0046] Furthermore, the workbench 5 is a split structure. It is conceivable that, because the volume of the fuel tank and the entire work platform is large, the diameter and weight of the annular workbench 5 are also large; designing the annular workbench 5 as a multi-section arc structure that can be spliced ​​not only facilitates transportation, but also reduces the difficulty of installing the workbench 5, which is conducive to improving the efficiency and safety of the workbench 5 during installation.
