The transmission shaft 61 is fixedly installed on the connecting shaft of the straight rod gate 5 and the gate machine 4. Both the bottom plate detection plate 62 and the railing detection plate 64 are slidably arranged on the column 1. The first lead screw 63 and the second lead screw 65 are both rotatably arranged on the column 1. The bottom plate detection plate 62 is threadedly connected with the first lead screw 63, and the railing detection plate 64 is threadedly connected with the second lead screw 65. The driving worm 66 is rotatably arranged inside the column 1 and fixedly connected with the transmission shaft 61. Both the two transmission worm wheels 67 are rotatably arranged inside the column 1 and are both in threaded transmission connection with the driving worm 66. The spiral direction of the thread on the first lead screw 63 is opposite to the spiral direction of the thread on the railing detection plate 64, ensuring that the overall structure can achieve the effect of detecting the height of the vehicle bottom plate and the railing, improving the overall performance and meeting the actual use requirements.

[0025] A transmission component 7 is arranged inside the column 1. The transmission component 7 includes a driven worm 71, a linkage worm wheel 72, an auxiliary gear 73, a rectangular magnet 74, a magnetic part 75, an auxiliary spring 76, a connecting rod 77 and a slider 78. The driven worm 71 is fixedly installed on the transmission worm wheel 67. The linkage worm wheel 72 is rotatably arranged inside the column 1 and is in threaded transmission connection with the driven worm 71, and the linkage worm wheel 72 is of an annular structure. The auxiliary gear 73 is fixedly installed on the side wall of the inner cavity of the linkage worm wheel 72. The rectangular magnet 74 is embedded on the surface of the auxiliary gear 73. The magnetic part 75 is fixedly installed on the end face of the connecting rod 77.

The slider 78 is slidably arranged inside the first lead screw 63 or the second lead screw 65, and the slider 78 is fixedly connected with the connecting rod 77. The cross-sectional area of the slider 78 is larger than the cross-sectional area of the connecting rod 77. The connecting rod 77 is located in the inner cavity of the auxiliary spring 76 and the connecting rod 77 does not contact the auxiliary spring 76. There are two transmission components 7 in total. A single transmission worm wheel 67 is in transmission connection with the first lead screw 63 or the second lead screw 65 through a single transmission component 7, making the overall structure design more reasonable, ensuring that the established structure can operate stably and reasonably, and thus achieving the purpose of establishing such structures in advance.

[0026] Working principle: When detecting the height of the vehicle floor and the railing, drive the vehicle to the inside of the detection range on the side of the column 1, and start the gate machine 4 to close the straight rod gate 5. At this time, the transmission shaft 61 fixed on the straight rod gate 5 rotates with the rotation of the straight rod gate 5. The transmission shaft 61 is fixedly connected to the driving worm 66 rotatably arranged inside the column 1. Therefore, the driving worm 66 rotates forward accordingly. The two transmission worm wheels 67 threadedly connected to the driving worm 66 also rotate forward. The driven worm 71 is fixed on the transmission worm wheel 67. The driven worm 71 is in transmission connection with the linkage worm wheel 72. Furthermore, the linkage worm wheel 72 rotates forward synchronously. The rectangular magnet 74 magnetically connected to the magnetic part 75 is also embedded on the auxiliary tooth 73 fixed on the inner surface of the linkage worm wheel 72. The magnetic part 75 is fixed with the auxiliary spring 76. The auxiliary spring 76 is fixedly connected to the slider 78 sliding inside the first lead screw 63 or the second lead screw 65. Therefore, in the initial state, under the action of the magnetic connection between the magnetic part 75 and the rectangular magnet 74, both the first lead screw 63 and the second lead screw 65 rotate with the forward rotation of the linkage worm wheel 72. Among them, the railing detection plate 64 slidably connected to the column 1 is also threadedly connected to the second lead screw 65, and the floor detection plate 62 also slidably connected to the column 1 is also threadedly connected to the first lead screw 63. Therefore, at this time, the railing detection plate 64 slides downward, and the floor detection plate 62 slides upward. When the floor detection plate 62 contacts the vehicle floor or the railing detection plate 64 contacts the vehicle railing and the first lead screw 63 or the first lead screw 63 cannot rotate forward, the driving worm 66, the transmission worm wheel 67, the driven worm 71 and the linkage worm wheel 72 continue to rotate. The generated force will squeeze the magnetic part 75, causing the magnetic part 75 to slide towards the first lead screw 63 or the second lead screw 65 and disengage from the rectangular magnet 74 and the auxiliary tooth 73. At this time, the state where the linkage worm wheel 72 rotates and the first lead screw 63 or the second lead screw 65 does not rotate can be realized. When one of the floor detection plate 62 or the railing detection plate 64 reaches the limit position in contact with the vehicle, the other can still continue to slide and contact the vehicle to cooperate with the scale 2 on the column 1 to complete the height detection. After the detection is completed, then raise the straight rod gate 5 through the gate machine 4. At this time, the transmission shaft 61 drives the driving worm 66, the transmission worm wheel 67, the driven worm 71 and the linkage worm wheel 72 to rotate reversely. Under the action of the auxiliary spring 76, the magnetic part 75 contacts the auxiliary tooth 73 again and cooperates with the rectangular magnet 74 to drive the first lead screw 63 or the second lead screw 65 to rotate with the reverse rotation of the linkage worm wheel 72. Furthermore, the first lead screw 63 or the second lead screw 65 returns to the initial position to facilitate the vehicle to drive out of the detection area.
