[0002] Usually, in a plane lifting and transverse moving type of three-dimensional parking garage, there is a lift car 3 that moves up and down in the lift shaft to deliver the stored (or retrieved) car to a certain parking space on each floor for storage (or to take the car from the parking space onto the lift car and deliver it to the car retrieval exit). The width of the lift car is the length of the car, and the length of the lift car is generally 3-4 times the width of the parking space. (For example, Figure 6 (As shown in the figure), the lift car 3 is provided with a track 6 along the length direction, and a movable rotating platform 4 is provided on the track 6. The movable rotating platform 4 is provided with a rotating track 2, and the AGV trolley 5 loaded with the car can move on the rotating track 2. When the rotating track 2 is aligned with the fixed track 1 on the parking space, the AGV trolley can drive from the rotating track 2 to the fixed track 1 to send the car to the designated location. In order for the movable rotating platform 4 to be able to rotate in the lift shaft, the diagonal dimension "F" of the movable rotating platform 4 must be smaller than the shaft width "A", that is, "A"> "B", and there is a gap of dimension "E" between the rotating track 2 and the fixed track 1. Since the width of the movable rotating platform 4 is about 1.4 meters, and the shaft width is also nearly 6 meters, then the dimension of "E" can reach about 180mm. The wheel diameter of the AGV is about 160mm, and it is impossible to drive from the rotating track 2 to the fixed track 1. Summary of the invention

[0003] The purpose of the present invention is to provide a rotating platform guide rail extension device for a stereo garage with a compact structure and good use effect.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the present invention is: a rotating platform guide rail extension device for a three-dimensional parking garage, which includes a rotating track and a support platform, and also includes a roller, a movable track and a toggle rocker, wherein a concave movable guide groove is provided at the end of the rotating track, a roller is provided in the rotating track at the bottom of the movable guide groove, the movable track is movably installed in the movable guide groove and supported by the roller, a limiting groove is provided on the rotating track on one side of the movable guide groove, a movable pin is movably installed in the limiting groove, one end of the movable pin is connected with the movable track, and the other end of the movable pin passes through the limiting groove and extends to form a power end, the support platform is located outside the power end, a rotating shaft is provided at the center of the bottom of the support platform, a toggle rocker is installed at the bottom of the rotating shaft through a flat washer and a toggle nut, the toggle rocker is used in conjunction with the power end of the movable pin, one end of the bottom of the support platform is connected with a first return spring, and the other end is connected with a second return spring, and the first return spring and the second return spring are both connected to the toggle rocker.

[0005] The toggle rocker is L-shaped, with a rotating sleeve fixed to the outer end of its horizontal arm. The bottom of the rotating shaft passes downward through the rotating sleeve and the flat washer and is connected to the toggle nut. The upper part of the vertical arm is used in conjunction with the power end of the moving pin. Spring connecting plates are fixed to both ends of the bottom of the support platform. One end of the first return spring and the second return spring is connected to the corresponding spring connecting plate, and the other end is connected to the inner end of the horizontal arm.

[0015] The present invention is further described below in conjunction with all the accompanying drawings. The rotating platform guide rail extension device for the three-dimensional parking garage described in this embodiment includes a rotating track 1, a support platform 10, a roller 2, a movable track 3, and a toggle rocker 4, wherein a concave movable guide groove is provided at the end of the rotating track 1, and a roller 2 is provided in the rotating track 1 at the bottom of the movable guide groove. The movable track 3 is movably installed in the movable guide groove and supported by the roller 2. A limiting groove is provided on the rotating track 1 on one side of the movable guide groove. There are two limiting grooves, which are respectively located on the rotating track 1 on both sides of the movable guide groove. Each limiting groove has a moving pin 12 connected to the movable track 3, wherein one moving pin 12 extends out of the movable track 3 to form a power end, and the other moving pin 12 is located in the limiting groove. The support platform 10 Located on the outside of the power end, a rotating shaft is provided at the center of the bottom of the support platform 10. A toggle rocker 4 is installed at the bottom of the rotating shaft through a flat washer 9 and a toggle nut 8. The toggle rocker 4 is L-shaped, and a rotating sleeve is fixed to the outer end of its cross arm. The bottom of the rotating shaft passes downward through the rotating sleeve and the flat washer 9 and is connected to the toggle nut 8. The function of the flat washer 9 is to separate the swinging toggle rod 4 so that there is a 1mm gap. The upper part of the vertical arm is used in conjunction with the moving pin 12. Spring connecting plates are fixed at both ends of the bottom of the support platform 10. The two spring connecting plates are in an "eight" shape when viewed from above, and the larger opening end thereof faces the rotating track 1. A spring adjusting rod 6 is connected to the spring connecting plate through an adjusting nut 5. One end of the first return spring 7 and the second return spring 11 are connected to the corresponding spring adjusting rod 6, and the other ends are connected to the inner end of the cross arm. The size and force parameters of the first return spring 7 are exactly the same as those of the second return spring 11. The swing lever 4 is tightened from two corresponding directions so that the preload force of the spring is greater than the thrust of the movable guide rail 3, that is, when the swing lever 4 pushes the movable guide rail 3, the spring will not be deformed.

[0016] The rotating track 1 of this embodiment is a rectangular cross section with a length of ≤3E (see Figure 6 ). At the front end of the rotating track 1, a large rectangular groove (movable guide groove) is opened downward from its upper surface. Its side length is about 2x10mm smaller than the side length of the rotating track 1, with a length ≥2E, and the front is open. On both sides of the large rectangular groove, there are 14mm wide through grooves (limiting grooves) with a length ≥E. At the bottom of the large rectangular groove, two small rectangular grooves with a width of 8.5mm, a depth of 4.5mm, and a length ≥2E are opened downward. These two rectangular grooves are used to place rollers, and the rollers basically cover the bottom of the large rectangular groove. The size of the roller is Ø5x8, the material is bearing steel, and the number is enough to cover the two small rectangular grooves (the bearing rollers are standard parts purchased from outside). The rollers are used to support the movable track 3.

[0017] The cross-sectional dimensions of the movable rail 3 are the same as (or slightly smaller than) the above-mentioned large rectangular groove (movable guide groove), and clearance fit is selected, and the length is the same as the length of the above-mentioned large rectangular groove. On both sides close to the rear end of the movable rail and at the same position as the above-mentioned 14mm wide through groove, Ø14mm movable pins are respectively provided. The outer end of the movable pin length on one side is flush with the outer side surface of the fixed rail, and the movable pin 12 on the other side should be extended by about ≤20mm. The extended movable pin 12 is pushed by external force, so that the movable guide rail 3 rolls on the rolling body. Since the rolling friction coefficient is very small, a small external force can push the movable guide rail to extend and retract freely.

[0018] The movable pin 12 is symmetrically provided with two pieces, one side is flush with the fixed guide rail 1, and the other side protrudes about <20mm (power end). The movable pin 12 can slide in the 14mm wide through groove on both sides of the fixed guide rail 1, and the swing lever 4 can move the movable guide rail by swinging it.

[0019] The working process of the above device is:

[0020] Active Track 3 Extended:

[0021] Leave empty spaces at the four ends of the two rotating rails, and install four sets of fixed rail components symmetrically (they can be fixed with screws). When the positions of the rotating rail 2 and the fixed rail 1 are aligned, the AGV trolley starts to move, and the swing lever 4 fixed at the bottom of the AGV trolley also moves with it. When the swing lever 4 hits the moving pin 12, it will drive the movable rail 3 to move. When the front end face of the movable rail 3 hits the end face of the fixed rail 1, the AGV trolley is still moving forward, and the movable rail stops. At this time, the swing lever 4 will swing backward, the spring 1 will stretch, and the spring 2 will retract. When the end block of the swing lever 4 slides over the moving pin 12, the trolley will continue to move forward until the instruction is completed.

[0022] The movable guide rail 3 is retracted:

[0023] After completing the instruction, the AGV trolley returns. When the swing lever 4 hits the moving pin 12, it drives the movable guide rail 3 to move back. When the rear end face of the movable guide rail 3 hits the rear end of the rectangular groove of the fixed guide rail 1, the movable guide rail stops. Since the AGV trolley is still moving, the swing lever 4 starts to swing, the spring 2 will stretch and the spring 1 will retract. When the end block of the swing lever 4 slides over the moving pin 12, the trolley will continue to move backward until the instruction is completed.

[0024] In order to avoid interference between the front and rear guide rail extension devices, the extension lengths of the front and rear movable pins 12 are different. If the length difference is 15-20mm, no interference will occur.

[0025] This solution has a simple structure and flexible action, and can also be used in other similar projects.

[0026] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made according to the shape and principle of the present invention should be included in the protection scope of the present invention.
