[0026] A relatively simple structure is formed by using a rail car 1, a lifting drive mechanism 2, a load-bearing column 3, a stacking platform 4, an overhead crane 5, a bottom rail 8 and a top rail 9, which is easy to maintain and can reduce costs; the rail car 1 is used to drive the load-bearing column 3, the overhead crane 5, the stacking platform 4 and the lifting drive mechanism to move, so that the stacking platform 4 can be moved to a specified horizontal position as needed, and the lifting drive mechanism is used to drive the stacking platform 4 to move vertically along the load-bearing column 3, so that the stacking platform 4 can be moved to a specified height position as needed, and the stacking platform 4 can store and retrieve goods in the storage warehouse, so that the stacker has a high degree of automation.

[0027] Furthermore, the overhead crane 5 includes a top moving seat 501, two top running wheels 502 and two top guide units; the top guide unit includes two top guide wheels 503; the two top running wheels 502 are respectively rotatably mounted on the left and right ends of the top moving seat 501, and both run on the top track 9; the top guide wheels 503 of the two top guide units are respectively rotatably mounted on the left and right sides of the upper side of the top moving seat 501; the two top guide wheels 503 of the same top guide unit clamp the top track 9; the upper end of the load-bearing column 3 is fixed on the top moving seat 501.

[0028] By utilizing the cooperation between the top rail 9, the top moving seat 501, the two top walking wheels 502 and the two top guide units, the guiding support for the top of the load-bearing column 3 is achieved. At the same time, the bottom rail 8 and the top rail 9 are parallel to each other, and their vertical positions correspond, so that the overhead crane 5 and the load-bearing column 3 can move following the rail car 1.

[0029] Furthermore, the rail vehicle 1 includes a bottom moving seat 101, a travel drive motor 105 and two bottom guide units; the bottom guide unit includes two bottom guide wheels 106; a driven travel wheel 102 and an active travel wheel 104 that travel on the bottom rail 8 are rotatably mounted on the left and right sides of the bottom moving seat 101; the travel drive motor 105 is used to drive the active travel wheel 104 to rotate; the bottom guide wheels 106 of the two bottom guide units are rotatably mounted on the left and right sides of the lower side of the bottom moving seat 101; the two bottom guide wheels of a bottom guide unit are synchronized. 106 clamps the bottom rail 8; a bottom mounting seat 103 is provided on the bottom moving seat 101; the lower end of the load-bearing column 3 is fixed on the bottom mounting seat 103; a busbar 10 is installed in parallel on one side of the bottom rail 8; a current collector matching the busbar 10 is installed on the bottom moving seat 101; bottom positioning QR codes are arranged at intervals on the bottom rail 8; a bottom scanner 107 for scanning the bottom positioning QR code is installed on the bottom moving seat 101; a lifting buffer 6 is installed on the upper side surface of the bottom moving seat 101 and the lower side surface of the top moving seat 501.

At the same time, the bottom guide wheel 106 of the bottom guide unit clamps the bottom track 8 to prevent the driven wheel 102 and the driving wheel 104 from derailing.

[0031] Furthermore, the stacking platform 4 includes a lifting frame 402 and a telescopic fork 404; the telescopic fork 404 is longitudinally installed on the lifting frame 402, and is used to lift the bottom of the goods and drive the goods to move longitudinally; guide frames 405 for guiding the goods are installed on the lifting frames 402 on the left and right sides of the telescopic fork 404; an adjusting bracket 403 is installed on the right edge of the lifting frame 402; a lifting track 401 is vertically installed on the load-bearing column 3; a sliding seat 408 that moves vertically along the lifting track 401 is installed on the adjusting bracket 403; a lifting positioning QR code is provided on the lifting track 401; a lifting code scanner 407 for scanning the lifting positioning QR code is installed on the adjusting bracket 403.

When the lifting code scanner 407 scans the corresponding QR code, the stacking platform 4 stops moving, and no manual operation is required, thereby improving the degree of automation;

[0033] The telescopic fork 404 is used to pick up and place the goods. After the stacking platform 4 has been moved, when the goods need to be taken out, the lifting drive mechanism 2 drives the lifting frame 402 to move down slightly, and the output end of the telescopic fork 404 extends under the goods. The lifting drive mechanism 2 drives the lifting frame 402 to move up and lift the goods, and the output end of the telescopic fork 404 retracts to complete the removal. When the goods need to be placed, the lifting drive mechanism 2 drives the lifting frame 402 to move up slightly, and the output end of the telescopic fork 404 extends. The lifting drive mechanism 2 drives the lifting frame 402 to move down, so that the edge of the goods is pressed on the shelf and disengaged from the telescopic fork 404, and the output end of the telescopic fork 404 retracts to complete the placement.

[0035] The traction machine 201 is used to retract and extend the traction steel rope 203 so that the traction steel rope 203 drives the stacking platform 4 to move vertically, thereby realizing vertical driving of the stacking platform 4.

[0036] Furthermore, track buffers 7 are installed on both ends of the bottom track 8. The track buffers 7 are used to reduce shock and buffer the rail vehicle 1.
