In some embodiments, the area of the vehicle loading plate 4 may be smaller than the area of the lifting platform 3 in consideration of practical circumstances. As shown in fig. 6 to 8, the size of the vehicle carrying board 4 in the horizontal direction is equal to the size of the lifting platform 3, so that the orthographic projection of the lifting platform 3 on the base 1 is overlapped with the orthographic projection of the vehicle carrying board 4 on the base 1, or as shown in fig. 9, the size of the vehicle carrying board 4 in the horizontal direction is smaller than the size of the lifting platform 3, so that the orthographic projection of the vehicle carrying board 4 on the base 1 is located in the orthographic projection of the lifting platform 3 on the base 1. In the above embodiment, the lifting platform 3 shields the car carrying board 4. In order to ensure that the height detector 5 can smoothly detect the detection area S, the lifting platform 3 is provided with a plurality of openings 31, the openings 31 penetrate through the lifting platform 3 in the lifting direction H, the plurality of openings 31 correspond to the plurality of detection areas S one to one, and the detection light rays emitted by the plurality of height detectors 5 reach the plurality of detection areas S through the plurality of openings 31.

For example, the tilt sensor 7 is a two-dimensional sensor and can detect the tilt angles of the horizontal plane of the elevating platform 3 in both the first horizontal direction X and the second horizontal direction Y. After the inclination sensor 7 measures the inclination of the lifting platform 3, an inclination detection signal is sent to the controller 6, and the controller 6 processes the inclination detection signal.

Regarding the number of the tilt sensors 7, those skilled in the art can set the tilt sensors according to actual requirements, and the number is not limited herein.
The height detector 5 and the tilt angle sensor 7 in the embodiment of the application are mutually independent, when the controller 6 judges that any one of the inclination detection is abnormal, an early warning signal can be sent out, the detection sensitivity is improved, and the safety accident is effectively prevented. In addition, in the process of ascending the lifting platform 3, the vehicle carrying plate 4 is arranged on the lifting platform 3, and the inclination degrees of the vehicle carrying plate and the lifting platform are the same. In case the controller 6 carries the gradient of sweep 4 and the gradient of lift platform 3 that judges through the slope detection signal that the high detection signal was judged when asynchronous, also can send early warning signal, remind the staff to inspect the elevating platform, consequently, the high detector 5 of this application embodiment and inclination sensor 7 can realize carrying the check-up of each other of sweep 4 and lift platform 3, avoid influencing whole transportation because of equipment problem itself, furthest has reduced the accident risk.
