At the same time, the airbag of the device is too large, and the efficiency of rapid inflation through the sensor after being impacted by external force is low, and it cannot achieve a good buffering effect. Therefore, it is necessary to propose a railway crossing vehicle barrier protection device to provide a new technical solution to solve the technical problems mentioned in the above patent.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] As described in the background art, since the contact area between the roller and the slide rail of the protective device set in this patent is small and is located at the bottom of the protective device, when one side of the device is impacted by external force, the roller on the side of the force is easy to separate from the outside of the slide rail, causing the protective device as a whole to roll over. At the same time, the airbag volume of the device is too large, and the efficiency of rapid inflation through the sensor after being impacted by external force is low, and it cannot achieve a good buffering effect.

[0029] In order to solve this technical problem, the utility model provides a railway crossing vehicle barrier protection device. By directly supporting the buffer part, it can reduce the occurrence of roller derailment when subjected to external force impact, thereby improving the overall stability of the protection device. At the same time, when not in use, the protection part can be folded and stored, thereby reducing the footprint of the protection device and improving the convenience of the protection device.

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] When in use, the wheels 3 cooperate with the track 1 to drive the vehicle body 2 to move between railway crossings;

[0035] When the vehicle body 2 moves to the center of the crossing, the buffer support assembly 4 can block the railway crossing and improve the overall stability of the vehicle body 2 when it is hit by external impact.

Through the coordination of the buffer support assembly 4 and the structure in the above embodiment, the buffer part is directly supported, which can reduce the occurrence of roller derailment when impacted by external force, thereby improving the overall stability of the protective device. At the same time, when not in use, the protective part can be folded and stored, thereby reducing the floor space of the protective device and improving the convenience of the protective device.

[0039] The railway crossing vehicle isolation and protection device provided in Example 1 is further optimized. Specifically, Figure 3-Figure 6 As shown, the buffer support assembly 4 includes a first rotating seat 6, a flip plate 7, a buffer pad 8, a second rotating seat 9, a third rotating seat 10 and a first rotating rod 11.

The third rotating seat 10 is fixedly connected to the inner side of the third rotating seat 10 with the first rotating rod 11.

[0040] The buffer support assembly 4 also includes a first fixed rod 12, a first support vertical plate 13, a second fixed rod 14, a second rotating rod 15 and an insert plate 16. A first movable groove is provided on both sides of the top of the vehicle body 2 away from the end of the first rotating seat 6. The first fixed rod 12 is fixedly connected to the inner side of the first movable groove. The first support vertical plate 13 is clearance-fitted to the inner side of the first movable groove, and the inner side of the bottom of the first support vertical plate 13 is clearance-fitted with the first fixed rod 12. The second fixed rod 14 is fixedly connected to the top between the two first support vertical plates 13, and the outer sides of both sides of the second fixed rod 14 are rotatably connected to the second rotating rod 15. The end of the second rotating rod 15 away from the center of the vehicle body 2 is fixedly connected to the insert plate 16.

[0041] The buffer support assembly 4 also includes a double-headed motor 17 and a screw 18. A second movable groove is opened at the center position of the top of the vehicle body 2. The double-headed motor 17 is fixedly connected to the center position inside the second movable groove. The screws 18 are fixedly connected on both sides of the double-headed motor 17. The side of the screw 18 away from the double-headed motor 17 is rotatably connected to the inner side of the second movable groove, and the two screws 18 are symmetrically arranged.

[0042] The buffer support assembly 4 also includes a fourth rotating seat 19, a second supporting vertical plate 20, a fifth rotating seat 21 and a third fixed rod 22. The fourth rotating seat 19 is gap-fitted on both sides of the inner side of the second movable groove. The bottom of the fourth rotating seat 19 is threadedly connected to the screw 18. The outer side of the top of the fourth rotating seat 19 is rotatably connected to the second supporting vertical plate 20. The inner side of the top of the second supporting vertical plate 20 is rotatably connected to the fifth rotating seat 21.

[0043] Specifically: when the vehicle body 2 moves to a suitable position, the double-headed motor 17 can be turned on, and the double-headed motor 17 drives the two screws 18 to rotate inside the second movable groove, thereby driving the two fourth rotating seats 19 threadedly connected to the screws 18 to move synchronously and in opposite directions inside the second movable groove;

[0044] When the two fourth rotating seats 19 move toward the side away from the double-headed motor 17, they can drive the bottom of the second support vertical plate 20 to move synchronously, so that the second support vertical plate 20 can be flipped to a vertical state. At this time, the top of the second support vertical plate 20 can drive the fifth rotating seat 21 to move upward synchronously. At the same time, the movement of the two fifth rotating seats 21 can drive the third fixing rod 22 to move upward synchronously on the top of the vehicle body 2.

[0045] When the third fixed rod 22 moves upward, it can drive the first rotating rod 11 and the second rotating rod 15, which are rotatably connected to the third fixed rod 22, to move upward synchronously, and drive the first rotating rod 11 and the second rotating rod 15 to a horizontal state;

[0046] By setting the first rotating rod 11, when the first rotating rod 11 is in a horizontal state, the flip plate 7 can be pushed away from the end of the third fixed rod 22. At the same time, by the rotation connection setting of the second rotating base 9 and the first rotating base 6, the flip plate 7 can be flipped, so that the flip plate 7 can be located on one side of the vehicle body 2 and in a vertical state, thereby driving the buffer pad 8 to synchronously flip to a vertical state. The setting of the buffer pad 8 can buffer the external force impact.

[0047] By setting the second rotating rod 15, when the second rotating rod 15 is in a horizontal state, it can drive the plug plate 16 fixedly connected to the second rotating rod 15 to move downward, so that the bottom of the plug plate 16 can be inserted into the ground. At this time, the plug plate 16 can support the second rotating rod 15;

[0048] By setting the connection between the plug plate 16, the second rotating rod 15 and the first rotating rod 11, the flip plate 7 can be supported. When the buffer pad 8 is hit, the impact force can be buffered and supported, thereby preventing the wheel 3 from leaving the track 1, and thus improving the stability of the vehicle body 2.

[0049] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.

[0050] Example 3:

[0051] This embodiment 3 is used to further disclose the specific structure of the warning component 5 on the premise of the above embodiments. By coordinating the warning component 5 with the structures in the above embodiments, a warning part is provided on the top of the buffer part, so that pedestrians and vehicles can be warned in advance at a long distance, thereby further improving the practicality of the protective device.
