DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 2 、 Figure 8 A stand-alone lifting platform system for a flat mobile stereo garage comprises a main frame 1, a lifting platform 2, a driving device 3 and a counterweight; the lifting platform 2 is provided with a leveling positioning system 4, and two sets of guide devices 5 are symmetrically arranged on the upper and lower sides of the lifting platform 2.

[0024] See also Figures 1 to 3 The main frame 1 comprises a main column 7 and a secondary column 8, with the drive device 3 mounted on top of the main column 7. The main column 7 is composed of a left column body, a right column body, and a bolted crossbeam. The main column 7 and the secondary column 8 are bolted together, with guide rails bolted to the sides of the left and right columns. The main frame 1 can be independently mounted on the ground foundation, eliminating the need for additional vertical attachment points and the structural requirements of other building walls, reducing architectural design complexity.

[0025] See also Figures 1 to 3 、 Figures 8 and 9 Each guide device 5 includes two guide wheel groups, which respectively cooperate with the guide rails on the left and right columns and can run on the two treads of the guide rails. One guide wheel group can achieve positioning in two directions, so the two guide wheel groups can achieve positioning in both left and right and front and back directions. The lifting platform 2 is connected to the drive device 3, and the lifting platform 2 is connected to the counterweight via a chain spanning the sprockets on both sides of the drive device 3. The counterweight can reasonably balance the weight of the lifting platform 2. Figures 1 to 2 The top of the left column and the top of the right column are both provided with mechanical safety stops to prevent the lifting platform 2 from falling off the guide rail.

[0026] See also Figures 1 to 2 、 Figures 4 to 6 The leveling positioning system 4 includes a hydraulic system 10 and four positioning devices 9 arranged at the four corners of the lifting platform 2. The hydraulic system 10 includes an independent hydraulic unit and an oil circuit, and the positioning device 9 includes a positioning cylinder 19, a guide pin 11 and a guide support 20; one end of the guide pin 11 is connected to the positioning cylinder 19 through the guide support 20, and the other end of the guide pin 11 is installed with a guide wheel 21, and the guide support plays the role of positioning the guide pin 11. The independent hydraulic unit is connected to the positioning cylinder 19 through the oil circuit, and the guide pins 11 at the four corners respectively correspond to the leveling positioning seats 22 arranged at the ends of the trolley running rails of each parking floor. The guide wheels 21 can enable the guide pins 11 to be accurately inserted into the positioning holes of the leveling positioning seats 22. The positioning cylinder 19 can drive the guide pins 11 to be simultaneously inserted into the positioning holes of the leveling positioning seats 22 of each parking floor under the drive of the independent hydraulic unit, thereby realizing the positioning and alignment of the trolley running rails. When the guide pins 11 of the four positioning devices 9 at the four corners of the lifting platform are all inserted into the positioning holes of the corresponding leveling positioning seats 22 of each parking floor, the trolley can be guaranteed to run back and forth safely on the running rails of the lifting platform 2 and the parking frame alley, thereby ensuring the smooth and safe movement of the trolley from the alley to the lifting platform 2.

[0027] See also Figures 1 to 2 、 Figure 7 The independent lifting platform system also includes a trolley positioning system 6, which is installed in the middle and rear position of the lifting platform 2 to realize the positioning of the upper stage device. The trolley positioning system 6 includes a positioning part, a turntable 13 and a drive structure 18 that are symmetrically arranged on the left and right sides of the lifting platform 2. The positioning part includes a guide seat 14, a positioning pin 12 and a connecting rod 16 arranged in sequence from the outside to the inside. The guide seat 14 is composed of a base and a guide sleeve. One end of the positioning pin 12 is inserted into the guide sleeve of the guide seat 14. The end of the positioning pin 12 can slide in the sleeve hole of the guide seat 14. The other end of the positioning pin 12 is connected to the turntable 13 through the connecting rod 16; the turntable 13 is connected to the drive structure 18, and the drive structure 18 is installed on the lifting platform 2. The trolley positioning seats 15 corresponding to the guide seats 14 on the left and right sides are symmetrically arranged on the transverse trolley, and the positioning pin 12 can be inserted into the positioning hole of the corresponding trolley positioning seat 15. The driving structure 18 drives the turntable 13 to rotate, thereby driving the positioning pin 12 to move and insert into the positioning hole of the trolley positioning seat 15.

[0028] See also Figure 1 A hydraulic buffer 17 is provided in the bottom foundation pit of the lifting platform 2 to ensure the safety of the equipment operation.

[0029] See also Figures 1 to 9 When working, the lifting platform 2 can move up and down along the track of the main frame 1, thereby realizing the function of transporting cars between layers. Travel tracks for transport trolleys can be set on both sides of the lifting platform 2. The transport trolleys can be directly transported from the tracks in the alley to the tracks of the upper lifting platform 2, so that the lifting platform 2 can be arranged at the end of the alley without the need for other structural support. The driving structure 18 drives the turntable 13 to rotate, driving the positioning pin 12 to move and insert it into the positioning hole of the trolley positioning seat 15. This combines the transverse trolley and the lifting platform 2 into a relatively static whole. The transverse trolley will not slip along the walking direction, ensuring the safety of the car and the transverse trolley when they are lifted and lowered together with the lifting platform 2; it solves the poor adaptability and possible safety hazards of the existing flat mobile stereo garage lifting platform. It can be seen from this that this lifting platform system can be independently set up on the ground foundation or installed on the wall of a building, and it has strong adaptability; it can be flexibly arranged at the end of the aisle or the side of the parking space in the stereo garage; the transverse trolley or handling device can be safely and reliably lifted and lowered with the lifting platform 2 to reach the designated floor, and can be accurately and stably positioned, which can well solve the problem of exchange between car layers in the stereo garage.
