Description

Technical Field

[0001] This utility model relates to the technical field of railway locomotive supporting facilities, specifically to a railway locomotive safety escalator. Background Technology

[0002] Railway locomotive escalators are an important component of railway locomotives, mainly used by drivers, manufacturing personnel, and visitors to get on and off railway locomotives.

[0003] A safety escalator for the side of a railway locomotive, with announcement number CN211166880U, is described. The upper end of the right upright is fixedly connected to a hinge, and the lower end of the right upright has a telescopic groove. A connecting rod is slidably connected within the telescopic groove. The right side of the connecting rod has evenly spaced adjustment holes, each threadedly connected to a screw. A short rod is rotatably sleeved at the lower end of the connecting rod, and support plates are fixedly connected to both ends of the short rod. A pad is fixedly connected to the lower end of the support plates. A handrail is hinged to the surface of the right upright, and an upper shaft seat is fixedly connected to the surface of the handrail. The handrail has a folding and retractable function, which not only increases the safety of the escalator but also reduces its space occupation and facilitates its folding. Furthermore, the telescopic pad not only increases the stability of the escalator but also allows users to adjust its tilt angle as needed.

[0004] Regarding the aforementioned related technologies, the inventors believe that existing railway locomotive escalators often use welding to fix the steps to the ladder frame. However, as the steps are used over time, they may break, affecting safety and requiring replacement. Welding makes disassembly and assembly of the steps cumbersome, severely impacting replacement efficiency. Therefore, we propose a railway locomotive safety escalator. Utility Model Content

An installation groove 4 is provided on the inner wall of the slot 3, and a limiting hole 6 is provided on the outer wall of the insert 5. The first limiting mechanism 7 includes a limiting block 13, a connecting rod 14, and a first spring 16. The limiting block 13 is fitted into the installation groove 4, and the size and structure of the limiting block 13 match those of the limiting hole 6. One end of the connecting rod 14 is fixedly connected to the outer wall of the limiting block 13, and the other end of the connecting rod 14 extends to the outside of the fixed rod 1. The first spring 16 is nested on the connecting rod 14 and is pressed between the outer wall of the limiting block 13 and the inner wall of the installation groove 4.

[0029] This utility model discloses a safety escalator for railway locomotives. A limiting block 13 has an insertion hole 17. Two arc-shaped grooves 19 are symmetrically formed on the inner wall of the insertion hole 17. Two guide grooves 18 are symmetrically formed on the limiting block 13. The two guide grooves 18 are connected to the insertion hole 17 and the arc-shaped grooves 19. A groove 20 is formed on the inner wall of each of the two arc-shaped grooves 19. A second limiting mechanism 8 includes a fixed base 21. A strip-shaped groove is formed on the fixed base 21, and the strip-shaped groove is connected to the insertion hole 17. A fixing plate 22 is provided on the inner wall of the groove, and an insertion rod 23 is inserted through the fixing plate 22. Two limiting rods 24 are symmetrically arranged on the side wall of the insertion rod 23 inside the strip groove. The end of the insertion rod 23 away from the limiting rod 24 extends through to the outside of the fixing seat 21 and is fixedly connected to a rotating head. The position and size of the limiting rod 24 match the guide groove 18, which can provide a fixing effect for the limiting block 13 and prevent the limiting block 13 from losing contact with the limiting hole 6 during use, thus affecting the overall stability.

[0030] The present invention relates to a railway locomotive safety escalator, wherein a pull ring 15 is fixedly connected to one end of a connecting rod 14 that extends through to the outside of a fixed rod 1. The pull ring 15 and the connecting rod 14 are integrated into one structure, which facilitates the movement of the limiting block 13 and improves the ease of operation.

[0031] This utility model discloses a railway locomotive safety escalator, in which handrails 9 are provided on the outer walls of two fixed rods 1, and anti-slip sleeves are nested on the handrails 9. The anti-slip sleeves are made of rubber, which can facilitate the staff to hold on and improve the safety when going up and down the escalator.

[0032] The present invention relates to a railway locomotive safety escalator, wherein both the limiting block 13 and the insert block 5 are provided with inclined surfaces, and the inclined surfaces of the two inclined surfaces are consistent, so that the insert block 5 can be directly inserted into the slot 3.

[0033] This utility model discloses a railway locomotive safety escalator. The outer wall of the fixing rod 1 is provided with a first fixing block 10 and a second fixing block 11. Both the first fixing block 10 and the second fixing block 11 are provided with mounting plates 12. Mounting holes are opened on the mounting plates 12. The length of the second fixing block 11 is greater than that of the first fixing block 10, which makes it easy to install it in a designated position. At the same time, it can make the escalator tilt at a certain angle, which makes it easier for workers to use the escalator.

[0034] This utility model discloses a railway locomotive safety escalator, in which a storage groove 27 is provided on the inner wall of the strip groove. The storage groove 27 corresponds to the guide groove 18 and the limiting rod 24 in position and size, and can provide a limiting and guiding function for the limiting rod 24. It can facilitate the direct insertion of the limiting rod 24 into the interior of the guide groove 18, avoiding the need to rotate back and forth to find the position.

[0035] This utility model discloses a railway locomotive safety escalator, in which a limiting plate 25 is embedded and connected in a strip groove, and an insert rod 23 is set through the limiting plate 25. A rotating plate is fixedly connected to the insert rod 23, and the rotating plate is rotatably connected to the limiting plate 25. A second spring 26 is nested on the insert rod 23. The second spring 26 is pressed between the outer wall of the limiting plate 25 and the outer wall of the fixing plate 22. Through the elastic force of the second spring 26, the limiting rod 24 can always maintain an engaged and locked relationship with the groove 20.

[0036] When using pedal 2, first press the rotating head, then rotate the insert rod 23 to make the limiting rod 24 rotate to the position of the guide groove 18. Then release the rotating head. At this time, the limiting rod 24 will automatically separate from the guide groove 18 under the elastic action of the second spring 26. At this time, the limiting block 13 loses its limiting effect. The operator can pull the pull ring 15 to separate the limiting block 13 from the limiting hole 6. At this time, pedal 2 loses its limiting effect and can be removed. When replacing pedal 2, simply align the insert block 5 on pedal 2 with the slot 3 and insert it. During the insertion process, the insert block 5 will push the limiting block 13 to move, causing it to retract into the mounting groove 4. After the insert block 5 is fully inserted, the limiting block 13 will retract into the mounting groove 4. The positioning hole 6 will move to the position of the limiting block 13. At this time, the limiting block 13 loses the external force and will enter the interior of the limiting hole 6 under the elastic action of the first spring 16 to limit the insertion block 5. Thus, the initial installation of the pedal 2 is completed. Next, the operator presses the rotating head to make the limiting rod 24 enter the interior of the guide groove 18. After the limiting rod 24 is in place, the rotating head is rotated to move the limiting rod 24 to the groove 20. Then the rotating head is released. The rotating head loses the external force and will engage with the groove 20 under the elastic action of the second spring 26, thereby providing a limiting effect for the limiting block 13. Through the double limiting effect, a stable installation effect can be provided for the pedal 2, and the overall operation is simple and convenient.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
