Patent publication number CN110409345B discloses a self-propelled rail-mounted guardrail. This guardrail features a sloped top frame and a drainage hole at the bottom of the rail body, connected to the chute. The sloped top prevents dust and impurities from accumulating on the upper surface of the guardrail, while the drainage hole prevents liquid from accumulating inside the chute, potentially impacting its operation.

[0003] However, it still has some shortcomings, such as the lack of protective devices, which often cannot effectively buffer the impact of external forces and cause damage, and the lack of a cleaning mechanism, so the track is easily blocked by debris, which greatly affects the stability of use.

[0018] Beneficial effects:

[0019] 1. When the rail-type self-propelled guardrail is in use, when the guardrail body receives an impact force, the guardrail body tilts to one side, which will cause the spring to be compressed and deformed, thereby offsetting part of its force, and protecting the guardrail body from being easily damaged, thereby ensuring the safety of pedestrians and vehicles.

[0026] See also Figure 1-3 The utility model provides a new technical solution: a rail-type self-propelled guardrail, comprising a track fixing frame 1, on which two tracks 2 are fixedly connected by bolts, and on opposite sides of the two tracks 2, a slide groove 3 is provided, and a guardrail base 4 is provided on the track fixing frame 1, and a guardrail body 14 is fixedly connected by bolts to the guardrail base 4;

[0029] The guardrail buffer protection mechanism includes two dual-axis motors 5, which are respectively bolted to the two ends of the guardrail base 4, and the outer surfaces of the two output shafts of the two dual-axis motors 5 are fixedly sleeved with first conical wheels 6.

[0030] Furthermore, multiple first conical wheels 6 are all fitted with the upper surface of the corresponding track 2, and a connecting rod 11 is provided on the guardrail base 4. Fixed blocks 9 are welded and fixed at both ends of the connecting rod 11, and second conical wheels 10 are rotatably connected to both sides of the two fixed blocks 9.

[0032] Furthermore, the studs 8 extend out of the outer surface of the movable hole 7 , the upper ends of the two studs 8 are threadedly connected with locking nuts 12 , and the outer surfaces of the two studs 8 are sleeved with springs 13 .

[0033] Furthermore, the two springs 13 are respectively located between the corresponding locking nuts 12 and the guardrail base 4. The outer surface of the guardrail base 4 is fixedly connected with a protective shell 15 by bolts. The protective shell 15 is used to protect the internal mechanical structure from being affected by the outside world.

[0034] Furthermore, the track cleaning assembly includes a brush plate 16, which is bolted to one side of the guardrail base 4. The brush on the brush plate 16 fits the track fixing frame 1 and the track 2. A dust suction device 17 is bolted to the brush plate 16, and the suction end of the dust suction device 17 extends between the two tracks 2. There are two track cleaning assemblies, which are located at both ends of the guardrail base 4 respectively.

[0035] Furthermore, during use, when the guardrail body 14 receives an impact force, the guardrail body 14 tilts to one side, which will cause the spring 13 to be compressed and deformed, thereby offsetting part of its force, and protecting the guardrail body 14 from being easily damaged, thereby ensuring the safety of pedestrians and vehicles. At the same time, the stable operating state means that the guardrail body 14 can maintain its structural integrity and functional effectiveness when moving or fixed, further enhancing safety. Under normal circumstances, the set spring 13 will always apply an elastic force to the guardrail base 4, so that the locking nut 12 and the stud 8 can be driven by its reaction force to drive the second conical wheel 10 to fit tightly against the top wall slope of the slide groove 3, so that the guardrail body 14 can be stably located on the two rails 2, so that when the dual-axis motor 5 is started, the guardrail body 14 can be driven to move stably along the two rails 2.

The fact that the track is not easily blocked means that the guardrail will not malfunction or shut down due to track blockage during movement, which ensures that the guardrail can operate continuously and stably, reduces traffic interruptions and delays caused by faults, and improves the reliability and stability of the transportation system.

[0037] Working principle: During use, when the guardrail body 14 receives an impact force, the guardrail body 14 tilts to one side, causing the spring 13 to be compressed and deformed, thereby offsetting part of its force, and protecting the guardrail body 14 from being easily damaged, thereby ensuring the safety of pedestrians and vehicles. At the same time, the stable operating state means that the guardrail body 14 can maintain its structural integrity and functional effectiveness when moving or fixed, further enhancing safety. Under normal circumstances, the set spring 13 will always apply an elastic force to the guardrail base 4, so that the locking nut 12 and the stud 8 can be driven by their reaction force to drive the second conical wheel 10 to fit tightly against the top wall slope of the slide 3, so that the guardrail body 14 can be stably located on the two rails 2, so that when the dual-axis motor 5 is started, it can drive the guardrail body 14 to move stably along the two rails 2.

[0038] Furthermore, by operating the two track cleaning assemblies, when the guardrail body 14 moves, the two activated track cleaning assemblies can clean the impurities, dust and other debris in the area between the two tracks 2, so that the debris can be cleaned by the moving brush plate 16 and then collected by the activated dust suction device 17.
