[0002] With the rapid development of my country's national economy, the number of small passenger cars and family sedans has entered a period of rapid growth. The shortage of parking spaces in large and medium-sized cities is becoming increasingly prominent, especially in bustling urban areas, office buildings, hotels, skyscrapers, shopping malls, residential communities, and tourist attractions, all of which are experiencing overcrowding. To adapt to the rapid development of the market economy and meet the urgent need for parking spaces, intelligent parking systems can fully utilize space, providing as many parking spaces as possible while occupying the same land area. This is of great significance to improving urban parking conditions. For the current parking spaces, most of the vertical lifting type of three-dimensional parking garage transfer platform is used to move the vehicle in a horizontal direction, or the vehicle loading plate is moved horizontally to store and retrieve the parked vehicle. This type of three-dimensional parking garage has a high level of automation and adopts a fully enclosed building structure. The parking safety is very high. It is usually necessary to turn the vehicle around on the transfer trolley, and the U-turn is usually achieved by rotation. The rotating disk must be constrained during the rotation process, otherwise the turntable may rotate relative to the vehicle when the transfer platform moves.

One end of the support shaft 100b is fixed to the center of the sliding roller 100a, and the other end of the support shaft 100b is fixedly connected to the support block 101. The support block 101 is rolled and arranged in the channel steel 100 through a plurality of parallel support shafts 100b, so that the locking rotation device can be fixed to the channel steel 100 through the support block 101 sliding connection. The support block 101 and the channel steel 100 can also be fixed by setting an electric lock. When the locking housing 8 moves forward to fasten the locking bolt fixing device or open it, due to the unevenness of the ground, the two rollers 4 slide up and down along the fixed guide rail seat 1, driving the locking rotating seat 2 and the rotating seat body 5 to slide up and down. The upper and lower rollers 4 can move up and down by cooperating with the fixed guide rail seat 1, and the locking housing 8 will also rotate along the rotating seat body 5, thereby also driving the supporting block 101 to slide in the channel steel 100 through the sliding roller 100a, thereby eliminating the influence of the uneven ground.
