[0027] like Figure 1-6 As shown, this relates to a multi-functional escalator for railway tank cars that can be used for high-mounted safety belts. It includes a platform 1, with support frames 3 fixedly connected to both sides of the upper end of the platform 1. First fixed seats 4 are fixedly connected to both sides of the upper end of the support frames 3. A support plate 2 is fixedly connected to one end of the platform 1 inside the support frame 3. Mounting frames 5 are fixedly connected to both sides of the lower end of the support plate 2. First mounting plates 10 are rotatably connected to both ends of the inner side of the support frame 3. Second mounting plates 11 are rotatably connected to both ends of the inner side of the mounting frames 5. Several footboards 13 are rotatably connected between the first mounting plates 10 and the second mounting plates 11. Support rods 14 are fixedly connected to both sides of the pedal 13 at one end of the platform 1. A second fixed seat 15 is fixedly connected to the upper end of the support rod 14. A protective rod 16 is provided between the first fixed seat 4 and the second fixed seat 15. A third connecting block 17 and a fourth connecting block 18 are fixedly connected to both ends of the protective rod 16, respectively. A fixed rod 19 is provided at one end of the second fixed seat 15. An arc-shaped hanging bracket 20 is provided at the upper end of the fixed rod 19. An adjustment component for adjusting the included angle is provided between the fixed rod 19 and the arc-shaped hanging bracket 20. A transmission component 21 is provided on the side of the second fixed seat 15.

[0028] As shown in the figure, a first rotating shaft 6 is fixedly connected to the upper outer side of the support frame 3. A first connecting block 7 is rotatably connected to the first rotating shaft 6. A hydraulic telescopic rod 8 is fixedly connected to the first connecting block 7. A second connecting block 9 is fixedly connected to one end of the hydraulic telescopic rod 8. A second rotating shaft 12 is fixedly connected to one side of the lower end of the second mounting plate 11. The second connecting block 9 is rotatably connected to the corresponding second rotating shaft 12. The hydraulic telescopic rod 8 can play a role in buffering and shock absorption.

[0029] As shown in the figure, the transmission assembly 21 includes a third rotating shaft 22 and a fourth rotating shaft 24 rotatably connected to both sides of the second fixed base 15. A first bevel gear 23 and a second bevel gear 25 are respectively fixedly connected to one end of the third rotating shaft 22 and the fourth rotating shaft 24. A connecting plate 26 is fixedly connected to the side of the second fixed base 15. A fifth rotating shaft 27 is rotatably connected to the connecting plate 26. A third bevel gear 28 and a fourth bevel gear 29 are respectively fixedly connected to both ends of the fifth rotating shaft 27. The third bevel gear 28 meshes with the first bevel gear 23, and the fourth bevel gear 29 meshes with the second bevel gear 25. A third connecting block 17 is connected to the first fixed base 15. The fixed seat 4 is rotatably connected, the fourth connecting block 18 is fixedly connected to the corresponding third rotating shaft 22, and the bottom end of the fixed rod 19 is fixedly connected to the fourth rotating shaft 24. During the unfolding process, the two ends of the protective rod 16 rotate around the first fixed seat 4 through the third connecting block 17 and rotate through the third rotating shaft 22 through the fourth connecting block 18. The third rotating shaft 22 drives the first bevel gear 23 to rotate, and the first bevel gear 23 drives the fifth rotating shaft 27, which is fixed to the third bevel gear 28, to rotate. Through the transmission of the fourth bevel gear 29 and the second bevel gear 25, the fourth rotating shaft 24 can be driven to rotate, which in turn drives the fixed rod 19 to rotate to a vertical state.

[0030] As shown in the figure, the adjustment assembly includes a first connecting seat 30, a second connecting seat 32, a third connecting seat 33, and a hydraulic cylinder 31. The first connecting seat 30 is fixedly connected to the front side of the fixed rod 19, the second connecting seat 32 is fixedly connected to the upper end of the fixed rod 19, the two sides of the bottom end of the arc-shaped hanging frame 20 are rotatably connected to the corresponding second connecting seat 32, and the third connecting seat 33 is fixedly connected to the front side of the arc-shaped hanging frame 20. The two ends of the hydraulic cylinder 31 are rotatably connected to the corresponding first connecting seat 30 and third connecting seat 33, respectively. In the retracted state, because the arc-shaped hanging frame 20 is relatively high, the arc-shaped hanging frame 20 is perpendicular to the fixed rod 19 under the adjustment of the adjustment assembly. When in the extended state, the hydraulic cylinder 31 drives the arc-shaped hanging frame 20 to rotate around the second connecting seat 32, so that the arc-shaped hanging frame 20 and the fixed rod 19 are in a vertical state.

[0031] Working principle: When not in use, manually pull the escalator to turn it into a vertical position. Figure 2 As shown, it is easy to store and will not obstruct the operation of railway tank cars. It can be unfolded by pushing the escalator. When unfolded, as... Figure 1As shown, the hydraulic telescopic rod 8 can act as a buffer and shock absorber. At this time, the first mounting plate 10 and the second mounting plate 11 are both rotated from horizontal to horizontal. When the first mounting plate 10 and the second mounting plate 11 are in the horizontal state, the pedal 13 is connected end to end, which facilitates the movement of workers. The bottom end of the outermost pedal 13 contacts the upper end of the railway tank car. Through the transmission component 21, specifically, during the unfolding process, the two ends of the protective rod 16 rotate around the first fixed seat 4 through the third connecting block 17 and the fourth connecting block 18 rotate through the third rotating shaft 22. The third rotating shaft 22 drives the first bevel gear 23 to rotate, and the first bevel gear 23 drives the third bevel gear... The fixed fifth rotating shaft 27 rotates, and through the transmission of the fourth bevel gear 29 and the second bevel gear 25, it can drive the fourth rotating shaft 24 to rotate, which in turn can drive the fixed rod 19 to rotate to a vertical state. Then, through the set adjustment component, it can drive the arc-shaped hanging frame 20 to rotate to a vertical state. Specifically, in the retracted state, because the arc-shaped hanging frame 20 is high, the arc-shaped hanging frame 20 is in a vertical state with the fixed rod 19 under the adjustment of the adjustment component. When in the unfolded state, the hydraulic cylinder 31 drives the arc-shaped hanging frame 20 to rotate around the second connecting seat 32, so that the arc-shaped hanging frame 20 and the fixed rod 19 are in a vertical state. The set arc-shaped hanging frame 20 makes it convenient for workers to hang safety belts.

[0032] Example 2:

[0033] In daily operations, operators need to use pipes that move horizontally, but the horizontal arrangement of the arc-shaped hanger 20 may hinder the movement of the pipes, so further design is required:

[0034] like Figure 7 As shown, each of the two fixing rods 19 has a fixing seat 35 fixed to its top. One end of the arc-shaped hanging bracket 20 is rotatably connected to one of the fixing seats 35 via a torsion spring 34, and the other end is connected to the other fixing seat 35 via a quick-opening assembly. The quick-opening assembly includes a spring 36 disposed inside a groove at one end of the arc-shaped hanging bracket 20. One end of the spring 36 is fixed with a locking block 37, which engages with an opening on the surface of the fixing seat 35.

[0035] When the arc-shaped hanging bracket 20 is obstructed laterally, the operator can press the locking block 37 to disengage the locking block 37 from the opening. Then, under the action of the torsion spring 34 at the other end, the arc-shaped hanging bracket 20 is lifted up and rotated to be in the same vertical line as the fixed rod 19 to avoid obstruction.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
