Description

Technical Field

[0001] This utility model relates to the technical field of platform protection devices, and in particular to a mobile railway platform protection device. Background Technology

[0002] In modern railway transportation, railway platform safety protection devices are important facilities to ensure passenger safety and maintain platform order. These devices aim to prevent accidents and improve platform safety, and fixed guardrails are often used to achieve isolation and protection.

[0003] In the process of using platform safety devices, traditional platform safety devices mostly adopt fixed guardrails. The design of traditional guardrails is often bulky, which not only occupies a lot of space, but also does not contribute to the overall aesthetics and space utilization of the platform. When it is necessary to extend or store them, the operation process is complicated and time-consuming.

[0004] Therefore, to address the aforementioned inconvenience in conveniently extending and storing the guardrail, a mobile railway platform protection device can be designed. When the platform protection device is in use, the counterweight drives the bearing plate to fall to the upper end of the limiting plate, thereby achieving the purpose of conveniently extending the guardrail. At the same time, through a clever gear transmission and spring reset mechanism, the convenient extension and storage of the guardrail is realized, effectively improving the safety and convenience of railway platforms. Utility Model Content

[0005] In order to overcome the problem that traditional fixed guardrails are complicated and time-consuming to extend or retract during use, which greatly reduces the efficiency of the platform, especially during peak hours, the speed of extending and retracting the guardrails directly affects the smoothness of passengers getting on and off the train, there is an urgent need to improve the system and make it inconvenient to extend and retract the guardrails.

[0006] The technical solution of this utility model is as follows: A mobile railway platform protection device, comprising a mobile guardrail, a cavity, a winding shaft, a protective net, a mobile post, an inner cavity, a drive shaft, a rotating gear, a lifting gear plate, a drive gear, a driven gear, a transmission gear chain, a driven shaft, a rotating wheel, a return spring, a limiting plate, a bearing plate, and a counterweight. A cavity is formed on the right side wall of the mobile guardrail, and a winding shaft is rotatably mounted inside the cavity. A mobile post is located on the right side of the mobile guardrail, and a protective net is wound around the side wall of the winding shaft. An inner cavity is formed inside the mobile post. The unit is equipped with a rotating drive shaft, and a drive gear is fixedly mounted on the side wall of the drive shaft. A driven shaft is rotatably mounted on the bottom wall of the moving column, and a driven gear is fixedly mounted on the side wall of the driven shaft. A transmission gear chain is installed inside the inner cavity. Two sets of rotating wheels are fixedly mounted at both ends of the driven shaft. A lifting gear plate is fixedly mounted inside the inner cavity. A rotating gear is fixedly mounted on the side wall of the drive shaft. A bearing plate is fixedly mounted on the upper end of the guide gear plate. A counterweight is mounted above the bearing plate. Multiple sets of return springs are installed inside the inner cavity. A limit plate is fixedly mounted inside the inner cavity.

[0007] Preferably, during the use of the platform protection device, when the guardrail is extended, the counterweight is first unlocked. At this time, the bottom of the counterweight contacts and presses against the top of the bearing plate. Under the weight of the counterweight, the bearing plate and the lifting gear plate can be driven to descend. During this process, multiple sets of return springs are stretched and deformed, storing force for subsequent return motion. When the lifting gear plate continues to descend, because the lifting gear plate meshes with the rotating gear, the lifting gear plate can drive the rotating gear and the drive shaft to rotate. The drive shaft can then drive the drive gear to rotate. Since the drive gear and driven gear mesh with the upper and lower ends of the transmission gear chain respectively, the drive gear can drive the transmission gear chain to rotate. The transmission gear chain can then... By rotating the driven shaft through the driven gear, the two rotating wheels at both ends can be rotated, thus allowing the moving column to move smoothly to the right. During this process, the moving column can pull one end of the protective net to unfold. When the counterweight causes the bearing plate to fall to the upper end of the limit plate, the lifting tooth plate stops descending, thus fully unfolding the protective net and achieving the purpose of conveniently extending the guardrail. When storing the guardrail, the above operation is reversed to achieve the purpose of conveniently storing the guardrail. In summary, this mobile railway platform protection device, through ingenious gear transmission and spring reset mechanism, realizes the convenient extension and storage of the guardrail, effectively improving the safety and convenience of railway platforms.

[0008] Preferably, the right end of the protective net is fixedly connected to the left side wall of the movable column, the driving gear is set at the upper end of the transmission gear chain and meshes with the transmission gear chain, the driven gear is set at the lower end of the transmission gear chain and meshes with the transmission gear chain, the lifting gear plate meshes with the rotating gear, and the bottom of the counterweight block abuts against the top of the bearing plate.

[0009] Preferably, a lifting rod is fixedly installed on the upper side wall of the counterweight, a guide groove is opened on the inner wall of the inner cavity, a guide rod is fixedly installed inside the guide groove, two sets of guide seats are installed on the side wall of the guide rod, the guide seats are slidably connected to the guide rod, and the side walls of both guide seats are fixedly connected to the upper and lower side walls of the lifting tooth plate.

[0010] Preferably, the reset spring is disposed inside the guide groove, with the upper end of the reset spring fixedly connected to the inner wall of the guide groove and the lower end of the reset spring fixedly connected to the top of the upper guide seat.

[0011] Preferably, two sets of fixing rings are fixedly installed on the inner walls of the upper and lower ends of the cavity. The fixing rings are equipped with spiral springs. One end of the spiral spring is fixedly connected to the side wall of one end of the winding shaft, and the other end of the spiral spring is fixedly connected to the inner wall of the fixing ring.

[0012] Preferably, a locking rod is provided on the top right side of the movable column, the side wall of the locking rod is slidably connected to the inner wall of the movable column, and a locking hole is provided through the upper end of the counterweight, with one end of the locking rod engaging with the inside of the locking hole.

[0013] Preferably, a limit ring is fixedly provided on the side wall of the locking rod, and a limit spring is fixedly provided on the inner wall of the limit ring, with one end of the limit spring being fixedly connected to the inner wall of the inner cavity.

[0014] The beneficial effects of this utility model are:

[0015] When the platform safety device is in use, during the extension of the guardrail, the counterweight is first unlocked. At this point, the bottom of the counterweight contacts and presses against the top of the support plate. Under the weight of the counterweight, the support plate and the lifting gear plate descend. During this process, multiple return springs are stretched and deformed, storing energy for subsequent return movements. As the lifting gear plate continues to descend, it meshes with the rotating gear, causing the rotating gear and drive shaft to rotate. The drive shaft then drives the drive gear to rotate. Since the drive gear and driven gear mesh with the upper and lower ends of the transmission chain respectively, the drive gear drives the transmission chain to rotate, and the transmission chain can then... The driven shaft is rotated by the driven gear, which in turn drives the rotating wheels at both ends to rotate, thus enabling the moving column to move smoothly to the right. During this process, the moving column can pull one end of the protective net to unfold. When the counterweight causes the bearing plate to fall to the upper end of the limit plate, the lifting tooth plate stops descending, allowing the protective net to be fully unfolded. This achieves the purpose of conveniently extending the guardrail. When storing the guardrail, the above operation is reversed to achieve the purpose of conveniently storing the guardrail. In summary, this mobile railway platform protection device, through ingenious gear transmission and spring reset mechanism, realizes the convenient extension and storage of the guardrail, effectively improving the safety and convenience of railway platforms.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a mobile railway platform protection device, including a movable guardrail 1, a cavity 2, a winding shaft 3, a protective net 4, a movable column 5, an inner cavity 6, a drive shaft 7, a rotating gear 8, a lifting gear plate 9, a drive gear 10, a driven gear 11, a transmission gear chain 12, a driven shaft 13, a rotating wheel 14, a return spring 15, a limiting plate 17, a bearing plate 16, and a counterweight 19. A cavity 2 is formed on the right side wall of the movable guardrail 1, and a winding shaft 3 is rotatably mounted inside the cavity 2. A movable column 5 is located on the right side of the movable guardrail 1, and a protective net 4 is wound around the side wall of the winding shaft 3. An inner cavity 6 is formed inside the movable column 5. The inner cavity 6 is equipped with a drive shaft 7, and a drive gear 10 is fixedly mounted on the side wall of the drive shaft 7. The bottom wall of the moving column 5 is equipped with a driven shaft 13, and a driven gear 11 is fixedly mounted on the side wall of the driven shaft 13. The inner cavity 6 is equipped with a transmission gear chain 12. Two sets of rotating wheels 14 are fixedly mounted at both ends of the driven shaft 13. The inner cavity 6 is equipped with a lifting gear plate 9. The side wall of the drive shaft 7 is fixedly mounted with a rotating gear 8. The upper end of the guide gear plate is fixedly mounted with a bearing plate 16. A counterweight block 19 is mounted above the bearing plate 16. The inner cavity 6 is equipped with multiple sets of return springs 15. The inner cavity 6 is equipped with a limit plate 17.

[0027] Please see Figure 5 and Figure 6The right end of the protective net 4 is fixedly connected to the left side wall of the movable column 5. The driving gear 10 is located inside the upper end of the transmission gear chain 12 and meshes with the transmission gear chain 12. The driven gear 11 is located inside the lower end of the transmission gear chain 12 and meshes with the transmission gear chain 12. The lifting gear plate 9 meshes with the rotating gear 8. The bottom of the counterweight block 19 abuts against the top of the bearing plate 16. When the lifting gear plate 9 continues to descend, it can drive the rotating gear 8 and the driving shaft 7 to rotate. The driving shaft 7 can then drive the driving gear 10 to rotate, and the driving gear 10 can then drive the transmission gear chain. The transmission chain 12 rotates, and the driven shaft 13 can be driven to rotate by the driven gear 11, which in turn drives the rotating wheels 14 at both ends to rotate. A lifting rod 18 is fixedly installed on the upper side wall of the counterweight 19. A guide groove 20 is opened on the inner wall of the inner cavity 6. A guide rod 21 is fixedly installed inside the guide groove 20. Two sets of guide seats 22 are installed on the side wall of the guide rod 21. The guide seats 22 are slidably connected to the guide rod 21. The side walls of both guide seats 22 are fixedly connected to the upper and lower side walls of the lifting gear plate 9. The lifting gear plate 9 can drive the upper and lower guide seats 22 to move downward along the guide rod 21.

[0028] Please see Figure 3 and Figure 7 The return spring 15 is located inside the guide groove 20. The upper end of the return spring 15 is fixedly connected to the inner wall of the guide groove 20, and the lower end of the return spring 15 is fixedly connected to the top of the upper guide seat 22. Under the elastic action of multiple sets of return springs 15, the upper guide seat 22 can be driven to move upward along the guide rod 21. Two sets of fixing rings 23 are fixedly installed on the inner walls of the upper and lower ends of the cavity 2. The fixing rings 23 are equipped with spiral springs 24. One end of the spiral spring 24 is fixedly connected to the side wall of one end of the winding shaft 3, and the other end of the spiral spring 24 is fixedly connected to the inner wall of the fixing ring 23. Under the elastic action of the upper and lower sets of spiral springs 24, the winding shaft 3 can be driven to rotate in the opposite direction. The winding shaft 3 can then drive the protective net 4 to achieve the effect of winding and storing.

[0029] Please see Figure 4 and Figure 8A locking rod 25 is provided on the top right side of the moving column 5. The side wall of the locking rod 25 is slidably connected to the inner wall of the moving column 5. A locking hole 26 is provided through the upper end of the counterweight 19. One end of the locking rod 25 is engaged with the inside of the locking hole 26. Pulling the locking rod 25 outward causes one end to disengage from the inside of the locking hole 26, thereby unlocking the counterweight 19. A limit ring 27 is fixedly provided on the side wall of the locking rod 25. A limit spring 28 is fixedly provided on the inner wall of the limit ring 27. One end of the limit spring 28 is fixedly connected to the inner wall of the inner cavity 6. Releasing the locking rod 25, under the elastic action of the limit spring 28, can drive one end of the locking rod 25 to insert into the inside of the locking hole 26, thereby locking the counterweight 19.

[0030] When the platform safety device is in use, and the guardrail is extended, firstly, the locking rod 25 is pulled outward, causing one end to disengage from the locking hole 26, thus unlocking the counterweight 19. At this time, the bottom of the counterweight 19 contacts and presses against the top of the bearing plate 16. Under the weight of the counterweight 19, the bearing plate 16 and the lifting toothed plate 9 can be driven to descend. During this process, the lifting toothed plate 9 can drive the upper and lower guide seats 22 to descend along the guide rod 21. At this time, the multiple sets of return springs 15 are stretched and deformed, storing force for the subsequent return movement.

[0031] As the lifting gear plate 9 continues to descend, it meshes with the rotating gear 8, causing the rotating gear 8 and the drive shaft 7 to rotate. The drive shaft 7 then drives the drive gear 10 to rotate. Since the drive gear 10 and the driven gear 11 mesh internally with the upper and lower ends of the transmission gear chain 12, the drive gear 10 drives the transmission gear chain 12 to rotate. The transmission gear chain 12, in turn, drives the driven shaft 13 to rotate via the driven gear 11, which in turn drives the rotating wheels 14 at both ends to rotate. This allows the moving column 5 to move smoothly to the right.

[0032] During this process, the movable column 5 can pull one end of the protective net 4 to unfold it. At this time, the other end of the protective net 4 can drive the winding shaft 3 to rotate. Furthermore, the upper and lower sets of spiral springs 24 are stretched and deformed, storing energy for the subsequent reset movement. When the counterweight 19 drives the bearing plate 16 to fall to the upper end of the limiting plate 17, the lifting toothed plate 9 stops descending, thereby enabling the protective net 4 to be fully unfolded, thus achieving the purpose of conveniently extending the guardrail.

[0033] When storing the guardrail, firstly, pull the locking rod 25 outwards. At this time, the limiting spring 28 is compressed and deformed. Then, pull the lifting rod 18 upwards to move the counterweight 19 to the top position of the moving column 5. Immediately afterward, release the locking rod 25. Under the elastic action of the limiting spring 28, one end of the locking rod 25 can be inserted into the locking hole 26, causing the counterweight 19 to be locked. When the counterweight 19 is disengaged from the upper end of the bearing plate 16, under the elastic action of multiple sets of return springs 15, the upper guide seat 22 can be driven to move upwards along the guide rod 21. The guide seat 22 can then drive the lifting gear plate 9 to move upwards. The lifting gear plate 9 can drive the drive shaft 7 and drive gear 10 to rotate in the opposite direction through the rotating gear 8. The drive gear 10 can then drive the driven gear 11 and driven shaft 13 to rotate in the opposite direction through the transmission gear chain 12. This can drive the two sets of rotating wheels 14 to rotate in the opposite direction, thereby driving the moving column 5 to move smoothly to the left.

[0034] Meanwhile, under the elastic action of the upper and lower sets of spiral springs 24, the winding shaft 3 can be driven to rotate in the opposite direction. The winding shaft 3 can then drive the protective net 4 to achieve the effect of winding and storing, thereby achieving the purpose of convenient storage of the guardrail. In summary, this mobile railway platform protection device, through ingenious gear transmission and spring reset mechanism, realizes the convenient extension and storage of the guardrail, effectively improving the safety and convenience of railway platforms.

[0035] Through the above steps, when the platform protection device is in use and the guardrail is extended, firstly, the counterweight 19 is unlocked. At this time, the bottom of the counterweight 19 abuts against the top of the bearing plate 16. Under the gravity of the counterweight 19, the bearing plate 16 and the lifting toothed plate 9 can be driven to descend. During this process, multiple sets of return springs 15 are stretched and deformed, storing force for subsequent return motion. When the lifting toothed plate 9 continues to descend, since the lifting toothed plate 9 meshes with the rotating gear 8, the lifting toothed plate 9 can drive the rotating gear 8 and the drive shaft 7 to rotate. The drive shaft 7 can drive the drive gear 10 to rotate. Since the drive gear 10 and the driven gear 11 are respectively meshed with the upper and lower ends of the transmission gear chain 12, the drive gear 10 can drive the transmission gear chain 12 to rotate. The transmission chain 12 can drive the driven shaft 13 to rotate via the driven gear 11, which in turn drives the rotating wheels 14 at both ends to rotate, thus enabling the moving column 5 to move smoothly to the right. During this process, the moving column 5 can pull one end of the protective net 4 to unfold. When the counterweight 19 drives the bearing plate 16 to fall to the upper end of the limit plate 17, the lifting gear 9 stops descending, thus fully unfolding the protective net 4 and achieving the purpose of conveniently extending the guardrail. When storing the guardrail, the above operation is reversed to achieve the purpose of conveniently storing the guardrail. In summary, this mobile railway platform protection device, through ingenious gear transmission and spring reset mechanism, realizes the convenient extension and storage of the guardrail, effectively improving the safety and convenience of the railway platform.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
