By setting up the railway maintenance passage, staff can complete various inspection and maintenance tasks more quickly and efficiently, which not only helps to shorten the equipment downtime, reduce the operation cost, but also improves the efficiency and safety of railway transportation.

[0003] During the railway maintenance process, a passage for personnel connection is required for work platforms at different heights. The width of the maintenance platform in traditional railway maintenance operations is limited, and the installation process is relatively cumbersome. In addition, there is generally no equipment for protecting personnel during the railway maintenance process in traditional technologies, and there are certain safety hazards when staff fall from the climbing ladder during work. Summary of the Utility Model

[0004] Aiming at the defects that the width of the maintenance platform in the existing railway vehicle maintenance and repair operations is limited, the installation process is relatively cumbersome, and in addition, there is generally no equipment for protecting personnel during the railway maintenance process in traditional technologies, and there are certain safety hazards when staff fall from the climbing ladder during work, the utility model provides an assembled straight ladder for the maintenance between the supports of an aerial platform for railway vehicle maintenance and repair.

[0005] The utility model adopts the following technical solutions to solve the above technical problems:

[0006] An assembled straight ladder for the maintenance between the supports of an aerial platform for railway vehicle maintenance and repair includes a base, a platform, a plurality of platforms, a buffer assembly, a safety rope assembly and a plurality of ladder components. Each ladder component includes two cylindrical blocks. A positioning rod is fixedly connected to the bottom of the cylindrical block. A positioning groove for the positioning rod to slide into is formed on the upper surface of the cylindrical block. A step rod is fixedly connected between the two cylindrical blocks. A convex block is fixedly connected to the outside of the cylindrical block. Arc-shaped guard cage plates are detachably installed on the outside of the cylindrical blocks at both ends of the step rod through bolts. The outer diameter of the positioning rod is equal to the inner diameter of the positioning groove. When the positioning rod enters the inside of the positioning groove, the outer wall of the positioning rod is in close fit with the inner wall of the positioning groove. Slide the positioning rod in one ladder component into the positioning groove in another ladder component, and operate in sequence to complete the installation of multiple ladder components. The installation of the guard cage and the main climbing ladder can be realized through multiple ladder components and arc-shaped guard cage plates.

[0007] Preferably, the buffer assembly includes a transverse groove formed on the surface of the base. A sliding rod is fixedly connected inside the transverse groove. Two sliders are symmetrically and slidably connected to the outside of the sliding rod. The tops of the two sliders are each hinged with a transmission rod. One end of each of the two transmission rods away from the slider is hinged to the bottom of the platform. When a staff member falls onto the surface of the platform, the impact force will strike the platform, causing the damping rod to deform. Additionally, when the platform is struck, it will squeeze the transmission rod, causing the two sliders to slide on the outside of the sliding rod under the action of the transmission rod.

[0008] Preferably, damping rods are fixedly connected to the four corners of the inner wall at the bottom of the transverse groove. The tops of the four damping rods are fixedly connected to the bottom of the platform. When the platform is vibrated by an external force, the damping rods convert the vibration energy into other forms of energy through the damping material or structure inside them, thereby reducing the vibration amplitude and effectively protecting the safety of personnel.

[0009] Preferably, buffer springs are wound and arranged between each slider and the side wall of the transverse groove on the outside of the sliding rod. One end of each buffer spring is fixedly connected to the outer side wall of the slider, and the other end of the buffer spring is fixedly connected to the inner wall of the transverse groove. When the slider moves, it will squeeze the buffer spring. When the buffer spring deforms, it will buffer the impact, thereby effectively protecting the safety of personnel.

[0010] Preferably, two fixed tubes are fixedly connected to the bottom of the base. A fixing groove for the positioning rod to slide into is formed at the top of the fixed tube. The outer diameter of the positioning rod is equal to the inner diameter of the fixing groove. When the positioning rod slides into the inside of the fixing groove, the outer wall of the positioning rod is in close fit with the inner wall of the fixing groove, thereby increasing the stability of the positioning rod when it is inside the fixing groove, and thus realizing the installation of the bottommost escalator assembly.

[0011] Preferably, the safety rope assembly includes a fixing plate detachably connected to the topmost platform. A safety rope body is installed outside the fixing plate. The staff member ties the safety rope body to their body, thereby effectively ensuring the safety of the staff member during the maintenance of the railway.

[0012] Preferably, an anti-slip pad is installed outside the tread rod, thereby effectively preventing the staff member from slipping off the surface of the tread rod during the process of climbing the ladder.

[0013] Preferably, handrails are fixedly installed on both sides of the anti-slip pad outside the tread rod. The staff member can hold the handrails to facilitate gripping when climbing up and down the ladder.

[0014] Preferably, a diagonal brace rod is fixedly installed on the outer side wall of the fixed tube. The diagonal brace rod can increase the stability of the fixed tube when it supports the fixed tube, thereby increasing the stability of the entire prefabricated straight ladder for maintenance between the high-altitude platforms for railway vehicle maintenance.

[0015] Preferably, the bottom of the slider is closely attached to the inner wall of the bottom of the horizontal groove, avoiding the deviation of the slider during the movement of the sliding rod, thereby increasing the stability of the slider during movement.

[0016] The utility model adopts the above technical solution, and compared with the prior art, it has the following technical effects:

[0017] (1) Slide the positioning rod of the bottommost escalator component into the inside of the fixing groove, thereby realizing the installation of the bottommost escalator component. Then, slide the positioning rod in one escalator component into the positioning groove inside another escalator component, and operate in sequence to complete the installation of multiple escalator components. Through multiple escalator components and the arc-shaped cage plate, the installation of the cage and the main climbing ladder can be realized. The assembled straight ladder for the maintenance between the high-altitude platforms of railway vehicle maintenance proposed in this application increases the width of the maintenance platform and is convenient for installation, greatly improving the operation efficiency and reducing the operation cost.

[0018] (2) The staff ties the safety rope body to the body, thereby effectively ensuring the safety of the staff during the railway maintenance process. When the staff accidentally falls onto the surface of the platform, the impact force will impact the platform, causing the damping rod to deform. The damping rod converts the vibration energy into other forms of energy through the damping material or structure inside it, thereby reducing the vibration amplitude and effectively protecting the safety of the personnel. In addition, when the platform is impacted, it will squeeze the transmission rod, causing the two sliders to slide outside the sliding rod under the action of the transmission rod. When the slider moves, it will squeeze the buffer spring, and the deformation of the buffer spring will buffer the impact, further protecting the safety of the personnel. Description of the Drawings

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] An assembled straight ladder for maintenance between supports of an aerial platform for railway vehicle maintenance, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , includes a base 1, a platform 2, several platforms 3, a buffer assembly, a safety rope assembly and several ladder components. The ladder component includes two cylindrical blocks 4. The bottom of the cylindrical block 4 is fixedly connected with a positioning rod 5. The upper surface of the cylindrical block 4 is provided with a positioning groove 6 for the positioning rod 5 to slide into. A step rod 7 is fixedly connected between the two cylindrical blocks 4. The outside of the cylindrical block 4 is fixedly connected with a convex block 8. Arc-shaped guard cage plates 9 are detachably installed on the outside of the cylindrical blocks 4 at both ends of the step rod 7 through bolts. The outer diameter of the positioning rod 5 is equal to the inner diameter of the positioning groove 6. When the positioning rod 5 enters the inside of the positioning groove 6, the outer wall of the positioning rod 5 is in close fit with the inner wall of the positioning groove 6. Slide the positioning rod 5 in one ladder component into the positioning groove 6 inside another ladder component, and operate in sequence to complete the installation of multiple ladder components. Through multiple ladder components and arc-shaped guard cage plates 9, the installation of the guard cage and the main climbing ladder can be realized.

[0030] Reference Figure 4 and Figure 6 Figure 6 , the buffer assembly includes a transverse groove 10 formed on the surface of the base 1. A slide bar 11 is fixedly connected inside the transverse groove 10. Two sliders 12 are symmetrically and slidably connected to the outside of the slide bar 11. The tops of the two sliders 12 are each hinged with a transmission rod 13. One end of each of the two transmission rods 13 away from the slider 12 is hinged to the bottom of the platform 2. When a staff member falls onto the surface of the platform 2, the impact force will strike the platform 2, causing the damping rod 14 to deform. In addition, when the platform 2 is struck, it will squeeze the transmission rod 13, causing the two sliders 12 to slide on the outside of the slide bar 11 under the action of the transmission rod 13.

[0031] Reference Figure 6 Figure 6 , damping rods 14 are fixedly connected to the four corners of the inner wall of the bottom of the transverse groove 10. The tops of the four damping rods 14 are fixedly connected to the bottom of the platform 2. When the platform 2 is vibrated by an external force, the damping rod 14 converts the vibration energy into other forms of energy through the damping material or structure inside it, thereby reducing the vibration amplitude and effectively protecting the safety of personnel.

[0032] Reference Figure 6 Figure 6 , buffer springs 15 are wound and arranged between each slider 12 and the side wall of the transverse groove 10 on the outside of the slide bar 11. One end of the buffer spring 15 is fixedly connected to the outer side wall of the slider 12, and the other end of the buffer spring 15 is fixedly connected to the inner wall of the transverse groove 10. When the slider 12 moves, it will squeeze the buffer spring 15. When the buffer spring 15 deforms, it will buffer the impact, thereby effectively protecting the safety of personnel.

[0033] Reference Figure 5 and Figure 7 Figure 7 , two fixing pipes 16 are fixedly connected to the bottom of the base 1. A fixing groove 17 for the positioning rod 5 to slide into is formed at the top of the fixing pipe 16. The outer diameter of the positioning rod 5 is equal to the inner diameter of the fixing groove 17. When the positioning rod 5 slides into the inside of the fixing groove 17, the outer wall of the positioning rod 5 is in close fit with the inner wall of the fixing groove 17, thereby increasing the stability of the positioning rod 5 when it is inside the fixing groove 17, and thus realizing the installation of the bottommost escalator assembly.

[0034] Reference Figure 5 Figure 5 , the safety rope assembly includes a fixing plate 18 detachably connected to the topmost platform 3. A safety rope body 19 is installed outside the fixing plate 18. The staff member ties the safety rope body 19 to the body, thereby effectively ensuring the safety of the staff member during the railway maintenance process.

[0035] Reference Figure 5 Figure 5 , an anti-slip pad 20 is installed outside the tread rod 7, thereby effectively preventing the staff member from slipping off the surface of the tread rod 7 during the process of climbing the ladder.

[0036] Referring to Figure 5 and Figure 7 , on the outside of the step rod 7 and on both sides of the anti-slip mat 20, handrails 21 are fixedly installed. When the staff grabs the handrails 21, it can facilitate the provision of a gripping point when people climb up and down the ladder.

[0037] Referring to Figure 5 , on the outer side wall of the fixed pipe 16, a diagonal brace 22 is fixedly installed. Through the diagonal brace 22, the stability of the fixed pipe 16 when supporting the fixed pipe 16 can be increased, thereby increasing the stability of the entire assembled straight ladder for the maintenance between the high-altitude platforms for railway vehicle maintenance.

[0038] Referring to Figure 6 , the bottom of the slider 12 is in close contact with the inner wall of the bottom of the transverse groove 10, avoiding the deviation of the slider 12 during the movement of the slide rod 11, thereby increasing the stability of the slider 12 during the movement.

[0039] The implementation principle of an assembled straight ladder for the maintenance between supports of an aerial platform for railway vehicle maintenance in an embodiment of the present utility model is as follows: Slide the positioning rod 5 of the bottommost ladder component into the interior of the fixing groove 17. When the positioning rod 5 slides into the interior of the fixing groove 17, the outer wall of the positioning rod 5 is in close fit with the inner wall of the fixing groove 17, thereby increasing the stability of the positioning rod 5 when it is inside the fixing groove 17, and thus realizing the installation of the bottommost ladder component. The diagonal brace 22 can increase the stability when the fixing pipe 16 supports the positioning rod 5, thereby increasing the stability of the entire assembled straight ladder for the maintenance between supports of the aerial platform for railway vehicle maintenance. The outer diameter of the positioning rod 5 is equal to the inner diameter of the positioning groove 6. When the positioning rod 5 enters the interior of the positioning groove 6, the outer wall of the positioning rod 5 is in close fit with the inner wall of the positioning groove 6. Slide the positioning rod 5 in one ladder component into the positioning groove 6 inside another ladder component, and operate in sequence to complete the installation of multiple ladder components. The installation of the guard cage and the main climbing ladder can be realized through multiple ladder components and the arc guard plate 9. The staff ties the safety rope body 19 to their body, thereby effectively ensuring the safety of the staff during the railway maintenance process. An anti-slip pad 20 is installed on the outside of the tread rod 7, thereby effectively preventing the staff from slipping off the surface of the tread rod 7 during the process of climbing the ladder. The staff can hold the handrail 21 to facilitate the staff to hold when climbing up and down the ladder. When the staff accidentally falls onto the surface of the platform 2, the impact force will impact the platform 2, and thus the damping rod 14 will deform. The damping rod 14 converts the vibration energy into other forms of energy through the damping material or structure inside it, thereby reducing the vibration amplitude and effectively protecting the safety of the personnel. In addition, when the platform 2 is impacted, it will squeeze the transmission rod 13, and thus the two sliders 12 will also slide on the outside of the slide rod 11 under the action of the transmission rod 13. When the slider 12 moves, it will squeeze the buffer spring 15, and the deformation of the buffer spring 15 will buffer the impact, thereby effectively protecting the safety of the personnel.
