Description

Technical Field

[0001] The utility model relates to the field of stereo garages, in particular to a guide device for steadily lifting a vehicle loading plate in a stereo garage. Background Art

[0002] With the development of vehicle parking garages, in order to facilitate the transportation of vehicles to different levels for storage and retrieval, special lifting equipment for vehicles is often needed. This equipment can not only replace the ramps for vehicles to enter and exit the garage, but also greatly save space and improve the utilization rate of the garage. Difficulty in parking and traffic congestion are also one of the concerns affecting the development of the automobile industry. The construction of a small-footprint, highly intelligent three-dimensional garage is also an effective way to alleviate this problem. However, the upper and lower parts of the circulating guide rails of the guide device for the existing vertical circulation garage are both double-rail structures. The vehicle loading plate has four guide wheels, and the upper and lower guide wheels on the same side are located on the same vertical line. The upper double guide rails of the circulating guide rails have an intersection. When the lower guide wheel of the vehicle loading plate passes through the intersection, the vehicle loading plate is prone to shaking, and even the lower guide wheel of the vehicle loading plate may go on the wrong track, resulting in serious accidents such as the vehicle loading plate overturning and the deformation and damage of the circulating guide rails.

[0003] The prior art CN202222301605.7 discloses a guide rail device for a vertical circulation type stereo garage, which includes a garage bracket, a car loading plate arranged in the garage bracket; the car loading plate is assembled on the vertical circulation guide assembly through an assembly plate, and is driven by the vertical circulation guide assembly to realize the vertical circulation of the car loading plate; the garage bracket is provided with a guide rail on the outer side of the corresponding car loading plate, and the guide rail includes a main rail and an auxiliary rail; the assembly plate is provided with a main wheel matching the main rail, an upper auxiliary guide wheel matching the upper auxiliary guide rail, and a lower auxiliary guide wheel matching the lower auxiliary guide rail; the upper auxiliary guide wheel is clamped into the upper auxiliary guide rail when the car loading plate enters the upper arc transition position; the lower auxiliary guide wheel is clamped into the lower auxiliary guide rail when the car loading plate enters the lower arc transition position; although this guide device can effectively improve the stability of the car loading plate in the vertical circulation type stereo garage in the bad weather of strong wind, it still has the following problems:

[0004] 1. The guide rails of the existing guide devices are all set around the frame, which to a certain extent limits the space utilization efficiency of the garage. Especially when the number of parking spaces needs to be increased or the parking space layout needs to be adjusted, the disassembly and assembly of the original guide rails greatly affects work efficiency. In addition, the carrier plate is subjected to large lateral forces during vertical circulation motion. Especially when the carrier plate moves up and down, if it encounters uneven loads or the center of gravity of the vehicle shifts, it is easy to cause the carrier plate to tilt, increasing the risk of system instability.

[0005] 2. In actual use, existing guide devices can experience increased wear between the guide rails and guide wheels due to the weight of the carrier plate and the dynamic loads generated by vehicles entering and exiting the vehicle, which in turn affects the service life and performance of the guide device. In particular, when the carrier plate's lower guide wheel passes through the guide rail intersection, it is subject to additional impact, which can cause wear or failure. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a guide device for the smooth lifting of the vehicle loading plate in a three-dimensional parking garage. By adopting the combination of curved guide rails and limit mechanisms to replace the existing circular guide rail design, not only the lateral force on the vehicle loading platform during vertical cyclic motion is reduced, but also curved guide rails are only provided at the upper and lower ends of the garage frame, which can greatly improve the space utilization efficiency and facilitate the adjustment of the parking space layout.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] Provided is a guide device for the smooth lifting of a car loading plate in a stereo garage, comprising: an arc-shaped guide rail, a guide column and a limit mechanism.

[0009] The arc guide rail includes an upper guide rail and a lower guide rail symmetrically arranged along the center line of the garage frame in the width direction, and the upper guide rail and the lower guide rail are respectively arranged at the upper and lower ends of the garage frame. The guide column is arranged on the cross beam above one end of the vehicle loading platform, and can cooperate with the upper guide rail and the lower guide rail to guide the vehicle loading platform so that the vehicle loading platform can move along the circulation path; the limiting mechanism includes a limiting push rod and a card embedding groove, and the limiting push rod and the card embedding groove are respectively arranged on the upper and lower sides of the vehicle loading platform and are located on the same vertical center line, and the limiting push rod can be embedded in the card embedding groove when the vehicle loading platform is located on the same vertical center line.

[0010] It should be noted that the upper guide rail and the lower guide rail are respectively arranged at the upper and lower ends of the garage frame, and are respectively arranged at the corners on both sides of the garage frame, which can guide the turning parts on the circulation path of the vehicle loading platform, and the limiting mechanism can limit the vehicle loading platform during the vertical lifting of the vehicle loading platform. Specifically: when the vehicle loading platform is vertically lifted, the limiting top rods of adjacent vehicle loading platforms will be embedded in the embedding grooves of adjacent vehicle loading platforms, so that the adjacent vehicle loading platforms can be locked with each other, so that even without vertical guide rails, the stability and safety of the system can be maintained; this solution reduces the load The car platform is subjected to lateral forces during vertical cyclic motion, and the curved guide rails can better adapt to the movement trajectory of the car platform, especially during the up and down movement of the car platform, which can effectively disperse the lateral forces and reduce the risk of tilting due to uneven load or vehicle center of gravity offset. The guide rails of traditional guide devices are usually arranged around the entire frame, which not only takes up more space, but also requires rearranging the guide rails when the parking layout needs to be adjusted or parking spaces need to be added, which is very inconvenient. The design of the utility model greatly improves the space utilization efficiency by only arranging curved guide rails at the upper and lower ends of the garage frame, and also facilitates the adjustment of the parking layout.

[0017] Preferably, guiding slopes are provided at the entrances of the guide groove and the arc-shaped groove.

[0018] It should be noted that the design of the guide bevel enables the guide column and the limit column to transition smoothly when entering the guide groove and the arc groove, reducing the resistance and impact force during entry, extending the service life of the guide column, the limit column and the guide rail, and reducing deviation and shaking.

[0019] Preferably, the garage frame includes a door-type underframe and a lifting frame, the lifting frame is coaxially arranged on the door-type underframe, and a positioning beam is provided on the door-type underframe along the width direction of the garage frame. The lower end of the lower guide rail is fixed on the positioning beam, and the upper end is fixed on the upper end cross beam of the door-type underframe and is located on both sides of the lifting frame.

[0020] It should be noted that the positioning beams set along the width direction of the garage frame on the door-type chassis ensure the precise installation position of the lower guide rail.

[0021] Preferably, the upper guide rail is arranged on the upper end of the garage frame through a guide rail frame, and the upper inner arc plate and the upper outer arc plate are respectively fixedly arranged on the guide rail frame.

[0022] It should be noted that the setting of the guide rail frame ensures the stable installation of the upper guide rail and enhances the overall structural strength of the upper guide rail; the guide rail frame, as an intermediate supporting structure, can effectively transfer and disperse the load, ensuring that the upper guide rail is not easily deformed or damaged during long-term use, and the setting of the guide rail frame can enable the upper guide rail to be pre-installed, reducing installation time and cost, and also facilitating subsequent inspection and maintenance.

[0023] Preferably, the guide rail frame includes a support frame and a positioning frame.

The support frames are symmetrically arranged at both ends of the positioning frame and are located on both sides of the garage frame, ensuring the precise alignment of the upper guide rail; and enables the upper guide rail to remain horizontal during installation, ensuring that the center line of the guide groove is completely consistent with the motion trajectory of the vehicle loading platform, thereby improving the accuracy and reliability of the guide. Through the combination of the positioning frame and the support frame, the upper guide rail can be quickly fixed to the upper end of the garage frame, reducing installation time and cost, and also facilitating subsequent inspection and maintenance.
