Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0025] The fuel tank grab handle of this application is described below with reference to the accompanying drawings.

[0026] like Figures 1 to 7As shown, this application provides a fuel tank handrail, which includes a handrail tube 10 and a mounting support assembly 20. The handrail tube 10 includes a handrail crossbar segment 11 and a first vertical bar segment 12 that extends downward from the end of the handrail crossbar segment 11. The mounting support assembly 20 includes an outer sleeve 21, a mounting base plate 22, and a support rod 23. The outer sleeve 21 is sleeved on the outside of the first vertical bar segment 12 and welded to the first vertical bar segment 12. The lower ends of the outer sleeve 21 and the support rod 23 are welded to the mounting base plate 22 at intervals, and the upper end of the support rod 23 is welded to the outer sleeve 21. The mounting base plate 22 is used for detachable connection with the fuel tank 40.

[0027] The handrail tube 10 includes a horizontal handrail section 11 and a first vertical handrail section 12. The horizontal handrail section 11 extends horizontally, and the first vertical handrail section 12 bends downward from the end of the horizontal handrail section 11. An outer sleeve 21 is fitted over the outside of the first vertical handrail section 12 and is welded to the first vertical handrail section 12 to ensure a stable and reliable connection. The lower ends of the outer sleeve 21 and the support rod 23 are welded to the mounting base plate 22 at intervals to ensure a stable and reliable connection between the outer sleeve 21 and the mounting base plate 22, and to allow the support rod 23 to be stably erected on the mounting base plate 22. Furthermore, the lower ends of both the outer sleeve 21 and the support rod 23 are welded to the mounting base plate 22. By using the mounting base plate 22, the installation and fixation of the outer sleeve 21 and the support rod 23 can be achieved simultaneously. Compared to installing the outer sleeve 21 and the support rod 23 separately, this improves the flatness and accuracy of the installation. The upper end of the support rod 23 is welded to the outer sleeve 21, and the support rod 23 can support the outer sleeve 21. The welding method improves the connection stability and reliability between the support rod 23 and the outer sleeve 21. The mounting base plate 22 is used for disassembly and connection with the fuel tank 40 to facilitate replacement of the fuel tank handrail after wear, thereby improving the flexibility of the fuel tank handrail.

[0028] This application improves the structural strength of the fuel tank handrail by installing an outer sleeve 21 over the first vertical rod section 12 and welding the first vertical rod section 12 to the outer sleeve 21, and welding the upper end of the support rod 23 to the outer sleeve 21, thereby improving the stability and reliability of the fuel tank handrail.

[0029] In the embodiments of this application, please refer to Figure 1 and Figure 2 The handrail tube 10 also includes a second vertical rod section 13. The first vertical rod section 12 and the second vertical rod section 13 are respectively bent downward from both ends of the handrail horizontal rod section 11. There are two mounting support components 20. The two mounting support components 20 are respectively corresponding to the first vertical rod section 12 and the second vertical rod section 13. The oil tank handrail also includes a connecting horizontal rod 30. The connecting horizontal rod 30 connects the outer sleeve 21 of the two mounting support components 20.

[0030] The first vertical segment 12 and the second vertical segment 13 are respectively bent downwards from the left and right ends of the handrail horizontal segment 11. The handrail horizontal segment 11, the first vertical segment 12, and the second vertical segment 13 are bent as a single unit, saving assembly steps, reducing assembly errors, and improving the structural strength of the handrail tube 10. Two mounting support components 20 are respectively set to correspond one-to-one with the first vertical segment 12 and the second vertical segment 13. By setting the first vertical segment 12, the second vertical segment 13, and the two mounting support components 20, the force on the left and right ends of the handrail horizontal segment 11 is more even, improving the structural strength of the fuel tank handrail.

[0031] Furthermore, the fuel tank handrail also includes a connecting crossbar 30 extending in the horizontal direction. The connecting crossbar 30 connects the outer sleeves 21 of the left and right mounting support components 20. By setting the connecting crossbar 30 for support, the structural stability of the fuel tank handrail is further improved.

[0032] Please refer to the embodiments in this application. Figure 1 and Figure 2 The support rod 23 and the connecting crossbar 30 are respectively located on the adjacent sides of the outer sleeve 21, and the connecting crossbar 30 is located on the upper side of the support rod 23. The lower side of the connecting crossbar 30 and the outer sleeve 21 are connected by a first reinforcing plate 31.

[0033] The support rod 23 is located on the front side of the outer sleeve 21. Specifically, the support rod 23 is positioned towards the inside of the fuel tank 40 to avoid reducing the passageway if the support rod 23 is positioned towards the outside of the fuel tank 40. The connecting crossbar 30 extends in the left-right direction. The support rod 23 and the connecting crossbar 30 are located on adjacent sides of the outer sleeve 21. Compared to a design where the support rod 23 and the connecting crossbar 30 are located on opposite sides of the outer sleeve 21, this design reduces the left-right dimensions of the fuel tank handrail and provides better support.

[0034] The connecting crossbar 30 is located on the upper side of the support rod 23. The lower side of the connecting crossbar 30 is connected to the outer sleeve 21 by a first reinforcing plate 31. By setting the first reinforcing plate 31, the connection stability between the connecting crossbar 30 and the outer sleeve 21 is strengthened, thereby further improving the structural stability of the fuel tank handrail.

[0035] In the embodiments of this application, please refer to Figures 3 to 5 The upper end of the outer sleeve 21 is provided with a first annular weld between the upper end and the first vertical rod segment 12, the lower end of the outer sleeve 21 extends out of the lower end of the first vertical rod segment 12, and the lower end of the outer sleeve 21 is provided with a second annular weld between the lower end of the outer sleeve 21 and the first vertical rod segment 12.

[0036] An outer sleeve 21 is fitted over the first vertical rod segment 12. A first weld is provided between the upper end of the outer sleeve 21 and the first vertical rod segment 12. The first weld is annular, ensuring a stable and reliable connection between the upper end of the outer sleeve 21 and the first vertical rod segment 12. Furthermore, a second weld is provided between the lower end of the outer sleeve 21 and the first vertical rod segment 12. The second weld is annular, ensuring a stable and reliable connection between the lower end of the outer sleeve 21 and the first vertical rod segment 12.

[0037] Specifically, the lower end of the outer sleeve 21 extends beyond the lower end of the first vertical rod section 12, so that a second annular weld can be provided between the lower end of the outer sleeve 21 and the first vertical rod section 12.

[0038] Based on this, the upper end face of the outer sleeve 21 is inclined.

[0039] The upper end face of the outer sleeve 21 is inclined so that the length of the first weld is longer, further improving the connection stability and reliability between the upper end of the outer sleeve 21 and the first vertical rod segment 12.

[0040] In the embodiments of this application, please refer to Figure 2 and Figure 5 The mounting base plate 22 has a first mounting hole 221. The outer sleeve 21 is inserted into the first mounting hole 221, and the lower end of the mounting base plate 22 extends out of the lower end of the outer sleeve 21. A third weld seam is provided between the lower end of the outer sleeve 21 and the wall of the first mounting hole 221, and a fourth weld seam is provided between the outer side of the outer sleeve 21 and the upper end of the mounting base plate 22.

[0041] The first mounting hole 221 penetrates the mounting base plate 22, and the outer sleeve 21 is inserted into the first mounting hole 221. The lower end of the mounting base plate 22 extends beyond the lower end of the outer sleeve 21, so that a third weld, which is annular, is formed between the lower end of the outer sleeve 21 and the wall of the first mounting hole 221. Furthermore, a fourth weld, also annular, is formed between the outer side of the outer sleeve 21 and the upper end of the mounting base plate 22. By providing the annular third and fourth welds, the outer sleeve 21 can be stably and reliably connected to the mounting base plate 22.

[0042] In the embodiments of this application, please refer to Figure 2 and Figure 5 The mounting base plate 22 has a second mounting hole 222. The support rod 23 is inserted into the second mounting hole 222, and the lower end of the mounting base plate 22 extends out of the lower end of the support rod 23. A fifth weld seam is provided between the lower end of the support rod 23 and the wall of the second mounting hole 222, and a sixth weld seam is provided between the outer side of the support rod 23 and the upper end of the mounting base plate 22.

[0043] The second mounting hole 222 penetrates the mounting base plate 22, and is spaced apart from the first mounting hole 221. The support rod 23 is inserted into the second mounting hole 222, and the lower end of the mounting base plate 22 extends beyond the lower end of the support rod 23, so that a fifth weld, which is annular, is formed between the lower end of the support rod 23 and the wall of the second mounting hole 222. Furthermore, a sixth weld, also annular, is formed between the outer side of the support rod 23 and the upper end of the mounting base plate 22. By providing the annular fifth and sixth welds, the support rod 23 can be stably and reliably connected to the mounting base plate 22.

[0044] In the embodiments of this application, please refer to Figure 2 and Figure 5 The lower end of the first vertical rod segment 12 is provided with a first sealing plate 121, which is welded to the inner cavity of the first vertical rod segment 12.

[0045] The first sealing plate 121 is used to seal the lower end of the first vertical rod segment 12 to prevent rainwater from entering and causing rust. The first sealing plate 121 is welded to the inner cavity of the first vertical rod segment 12 so that the first sealing plate 121 can be stably and reliably installed in the inner cavity of the first vertical rod segment 12. Furthermore, the installation of the first sealing plate 121 can also improve the structural strength of the first vertical rod segment 12.

[0046] It is understandable that, in the case of a second vertical rod segment 13, a first sealing plate 121 may also be provided inside the lower end of the second vertical rod segment 13, and the first sealing plate 121 is welded to the inner cavity of the second vertical rod segment 13.

[0047] In the embodiments of this application, please refer to Figure 2 and Figure 5 The lower end of the support rod 23 is provided with a second sealing plate 231, which is welded to the inner cavity of the support rod 23.

[0048] The second sealing plate 231 is used to seal the lower end of the support rod 23 to prevent rainwater from entering the support rod 23 and causing rust. The second sealing plate 231 is welded to the inner cavity of the support rod 23 so that the second sealing plate 231 can be stably and reliably installed in the inner cavity of the support rod 23. Furthermore, the installation of the second sealing plate 231 also increases the structural strength of the support rod 23.

[0049] In the embodiments of this application, please refer to Figure 1 and Figure 2 The support rod 23 includes an integrally bent first support part 232 and a second support part 233. The first support part 232 is welded to the outer sleeve 21, and the second support part 233 extends in the same direction as the outer sleeve 21. The end of the second support part 233 away from the first support part 232 is welded to the mounting base plate 22.

[0050] The first support portion 232 and the second support portion 233 are integrally bent structures, saving assembly steps and reducing assembly errors. The first support portion 232 is welded to the outer sleeve 21. Specifically, the end profile of the first support portion 232 is set to an arc shape that matches the shape of the outer sleeve 21, so that the first support portion 232 can be stably connected to the outer sleeve 21. The second support portion 233 extends in the same direction as the outer sleeve 21, and extends vertically. The end of the second support portion 233 away from the first support portion 232 is welded to the mounting base plate 22, so that the support rod 23 is stably erected on the mounting base plate 22.

[0051] Based on this, please refer to Figure 4 and Figure 5 The mounting support assembly 20 also includes a second reinforcing plate 24. The two ends of the second reinforcing plate 24 are welded to the second support part 233 and the outer sleeve 21, respectively, and the middle part of the second reinforcing plate 24 is provided with an inwardly recessed arc-shaped stress relief part 241.

[0052] One end of the second reinforcing plate 24 is welded to the outer sleeve 21, and the other end of the second reinforcing plate 24 is welded to the first support portion 232. The second reinforcing plate 24 extends in the front-rear direction. By setting the second reinforcing plate 24, the connection stability and reliability between the support rod 23 and the outer sleeve 21 are improved. Furthermore, the middle part of the second reinforcing portion is provided with an inwardly recessed arc-shaped stress relief portion 241. By setting the arc-shaped stress relief portion 241, the overall fatigue strength and reliability of the structure are improved.

[0053] Specifically, the number of second reinforcing plates 24 can be at least two, and at least two second reinforcing plates 24 are spaced apart along the length direction of the outer sleeve 21. The structural stability is further improved by setting at least two second reinforcing plates 24.

[0054] In the embodiments of this application, please refer to Figure 6 The mounting support assembly 20 also includes a third reinforcing plate 27, which is connected between the outer sleeve 21 and the mounting base plate 22. By setting the third reinforcing plate 27, the connection stability and reliability between the outer sleeve 21 and the mounting base plate 22 are further improved, and the structural strength of the fuel tank handrail is further improved.

[0055] In the embodiments of this application, please refer to Figure 6 The height of the outer sleeve 21 is greater than half the height of the first vertical rod segment 12, so that the outer sleeve 21 provides better support and reinforcement for the first vertical rod segment 12, and the height of the support rod 23 can be higher.

[0056] In addition, this application also provides an excavator, which includes a fuel tank 40 and a fuel tank handle as described above.
