[0002] Nowadays, the increasing population in cities has led to the gradual increase in road congestion and parking space shortage in cities. This situation has a negative impact on traffic flow and the quality of urban life. Traditional ground parking lots can no longer meet the growing number of vehicles. In the field of urban traffic management and parking equipment, parking problems are becoming increasingly prominent, and urban parking space shortages, congestion and environmental pollution have attracted widespread attention. Although traditional parking equipment, such as underground parking lots and flat parking lots, have certain efficiency, they have problems such as large space occupation, low operating efficiency, large environmental impact and insufficient safety. These problems urgently need innovative solutions. The development of liftable car loading platforms has become a potential way to solve urban parking problems, because they can effectively utilize limited land space and increase the capacity and efficiency of parking spaces. For this reason, liftable parking spaces are also popular in the market.

[0027] The limiting mechanism includes a fixed box 6, which is fixedly connected to the vehicle loading plate 5. A movable groove is provided in the fixed box 6. A limiting plate 10 is provided in the upper part of the movable groove so as to be movable left and right. A load-bearing plate 11 is provided at the lower end of the limiting plate 10, and the left end of the load-bearing plate 11 is rotatably connected to the fixed box 6.

[0028] When the load-bearing plate 11 rotates to the horizontal, the upper surface is in contact with the lower surface of the limit plate 10, and the upper surface of the limit plate 10 is in contact with the upper surface of the moving groove in the fixed box 6. A limit bar 16 is fixedly arranged on the upper surface of the load-bearing plate 11, and a limit bar 16 groove is provided on the lower surface of the limit plate 10. When the load-bearing plate 11 is horizontal, the limit bar 16 is located in the limit bar 16 groove. The front and rear sides of the limit plate 10 are provided with moving grooves, and the front and rear sides of the moving groove in the fixed box 6 are respectively fixed with guide bars 13, and the guide bars 13 are located in the moving grooves so as to be movable left and right.

[0029] A return spring 12 is respectively arranged in the moving grooves on the front and rear sides, and the left and right ends of the return spring 12 are respectively fixedly connected to the left end of the moving groove and the left end of the guide bar 13. The lower end of the chain is fixedly connected with a connecting rod 7, a strip groove 1 8 is opened on the upper part of the fixed box 6, and a strip groove 2 is opened in the middle of the limit plate 10. The connecting rod 7 passes through the strip groove 1 8 and the strip groove 2 on the upper part of the fixed box 6, and the lower end of the connecting rod 7 is connected to the load-bearing plate 11. A rotating block 18 is fixedly arranged at the lower end of the connecting rod 7, and the lower end of the rotating block 18 is rotatably connected to the middle of the load-bearing plate 11.

[0030] The middle part of the connecting rod 7 is provided with an extrusion block 9 which can move up and down. The upper surface of the extrusion block 9 is an arc-shaped surface structure. The extrusion block 9 is located in the fixed box 6. An extrusion spring 15 is provided between the extrusion block 9 and the rotating block 18. A row of card slots 14 are evenly provided on the side of the support column 2 from top to bottom. The limit bar 16 on the limit plate 10 can be moved up and down and connected in the card slot 14.

[0031] When the utility model is in use, the vehicle loading plate 5 can be moved up and down by the drive of the chain. A limit mechanism is arranged between the chain and the vehicle loading plate 5 to prevent the vehicle loading plate 5 from suddenly falling sharply when the chain suddenly loses power, causing a safety hazard. When the chain loses power (the chain suddenly breaks or the rear end of the chain suddenly loses the force to pull the vehicle loading plate 5), the extrusion block 9 moves upward under the elastic force of the extrusion spring 15, so that the load-bearing plate 11 rotates downward. During the rotation of the load-bearing plate 11, the limit bar 16 disengages from the limit bar 16 groove, thereby releasing the restriction on the left and right movement of the limit plate 10, and the limit plate 10 is pulled along the guide plate 11 by the pulling force of the reset spring 12. The guide bar 13 moves to the right, and the limit plate 10 extends out of the right side of the fixed box 6. During the falling process of the vehicle loading plate 5, the right end of the limit plate 10 enters the slot 14 on the support column 2. The bottom of the slot 14 is provided with a slot that cooperates with the limit bar 16 slot on the limit plate 10. Therefore, after the chain suddenly breaks or loses power, the limit mechanism on the vehicle loading plate 5 will automatically lower the limit plate 10 to pop out and engage it with the slot 14 on the support column 2, preventing the vehicle loading plate 5 from continuing to move downward, thereby avoiding safety accidents. This application is set for the technical solution in the background technology that drives the entire vehicle loading plate to move up and down by a chain or wire rope.
