[0002] A multi-story parking garage is a mechanical or mechanical equipment system used to store and retrieve vehicles in large quantities. Common multi-story parking garages are divided into lifting and transverse movement types, plane movement types, aisle stacking types, vertical lifting types, etc. The driver drives the vehicle into the empty space on the bottom floor of the multi-story parking garage, and the garage control system then moves the vehicle to different parking spaces through reasonable transfer.

[0003] In practice, the synchronous lifting mechanisms used in existing multi-story parking garages can be roughly divided into two categories. One type is mechanical synchronous lifting mechanisms, which primarily utilize rack and pinion transmissions. These mechanisms are complex, bulky, require high control precision, and are expensive to manufacture. The other type is electrical synchronous lifting mechanisms, which have complex control procedures. In mainstream garage applications, these mechanisms are subject to numerous factors affecting their proper operation, resulting in poor operating precision and unreliable operation.

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, the four-point synchronous lifting chain combination structure used in the stereo garage includes a load-bearing frame 1, a chain structure 2, a driving device 3 and a lifting platform 4.

[0025] It should be noted that this structure features a built-in chain, offering dust and water resistance, adapting to a variety of outdoor working environments and offering low maintenance costs. This structure protects against wind, sun, rain, and other natural damage, minimizing maintenance and extending its service life. It also boasts a clean, aesthetically pleasing appearance.

[0026] In the figure, a drive device 3 is mounted on a load-bearing frame 1 and is used to drive a chain structure 2. These chain structures 2 are connected to the four corners of a lifting platform 4. Two sets of these chain structures 2 are arranged on either side of the lifting platform 4. This structure offers reliable transmission and simplicity. Only a single drive device is required to drive the chain structures on both sides, achieving synchronous lifting of the four lifting chains. Compared with existing mechanical synchronous lifting mechanisms, this simplifies the rack and pinion structure or electrical synchronization mechanism, significantly reducing manufacturing costs.

[0027] Specifically, the driving device 3 includes a driving motor 301, a driving shaft 302, a driving gear 303 and a driving chain 304, wherein: the rotating shaft of the driving motor 301 is connected to the driving shaft 302 through a coupling; the two ends of the driving shaft 302 are respectively provided with driving gears 303, and the driving gears 303 are respectively connected to the proximal follower gears 2011 on both sides through the driving chain 304.

[0028] Specifically, the chain structure 2 includes a proximal follower shaft 201, a distal follower shaft 202, a guide shaft 203, an annular chain 204, a proximal lifting chain 205 and a distal lifting chain 206; the proximal follower shaft 201 is sequentially provided with a proximal follower gear 2011, a proximal rotating gear 2012 and a proximal lifting guide gear 2013 from the outside to the inside, and the three gears rotate independently; the distal follower shaft 202 is sequentially provided with a distal rotating gear 2021 and a distal lifting guide gear 2022 from the outside to the inside, and the two gears rotate independently; the guide shaft 203 is arranged on the inner side adjacent to the distal follower shaft 202, and the distal follower shaft 202 is provided with a guide gear 2011 31; the annular chain 204 is sleeved on the proximal rotating gear 2012 and the distal rotating gear 2021; the upper end of the proximal lifting chain 205 is fixed at the upper inner position of the annular chain 204, the middle part of the proximal lifting chain 205 is wrapped around the proximal lifting guide tooth 2013, and the lower end of the proximal lifting chain 205 naturally droops and is connected to the lifting platform 4; the upper end of the distal lifting chain 206 is fixed at the lower inner position of the annular chain 204, the middle part of the distal lifting chain 206 first passes through the lower side of the guide gear 2031, and then is wrapped around the distal lifting guide tooth 2022, and the lower end of the distal lifting chain 206 naturally droops and is connected to the lifting platform 4.

[0029] In the figure, the lifting platform 4 is composed of cross beams 401 at the front and rear ends and a load-bearing plate 402 in the middle. Comb structures 403 are provided on the left and right sides of the load-bearing plate 402 and at the position of the parking wheels. The comb structure 403 is used to cooperate with the spline to move the vehicle. Guide wheels 404 are provided at both ends of the cross beam 401 of the lifting platform 4. The guide wheels 404 can move along the vertical slide groove of the central column 101 of the load-bearing frame 1.

[0030] In actual operation, the driving machine 301 can be an electric motor or a hydraulic motor. When the driving machine 301 drives the driving long shaft 302, the driving gear 303 and the driving chain 304 to rotate counterclockwise, the proximal follower gear 2011 on the proximal follower shaft 201 also rotates counterclockwise. Since the proximal follower gear 2011 and the distal rotating gear 2021 are covered with an annular chain 204, at this time, the annular chain 204 also rotates counterclockwise, and the top end of the proximal lifting chain 205 is fixed above the annular chain 204. The counterclockwise rotation of the chain 204 drives the proximal lifting chain 205 to rotate counterclockwise around the proximal lifting guide gear 2013, achieving an upward lifting effect; the top end of the distal lifting chain 206 is fixed below the ring chain 204. Since the counterclockwise rotation of the ring chain 204 drives the distal lifting chain 206 to rotate counterclockwise around the guide gear 2031 and clockwise around the distal lifting guide gear 2022, achieving an upward lifting effect, the synchronous rotation of the drive gear 303 will achieve a synchronous rise of the lifting chains at the four corners. When synchronous descent is required, the driver 301 only needs to drive the drive shaft 302, the drive gear 303 and the drive chain 304 to rotate clockwise.
