[0049] The present invention also provides a method for transferring a stacker crane to switch between multiple lanes, using the transport vehicle described above, and the steps of the transfer method are as follows:

[0050] S1: The transport vehicle movement instruction signal is transmitted to the vehicle-mounted wireless communication mobile unit 10 via the ground wireless communication fixed unit 16. The PLC in the vehicle-mounted control cabinet 11 receives the instruction and drives the travel drive motor 102 of the vehicle body travel mechanism 1 to work. The travel drive motor 102 of the vehicle body travel mechanism 1 drives the driving wheel of the vehicle body travel mechanism 1 to rotate, thereby driving the transport vehicle to move.

[0051] S2: Then, the vehicle-mounted laser ranging sensor unit 9 is used to perform addressing and drive the transport vehicle to stop at the position required by the instruction. Since the transport vehicle is driven by friction wheels, there will be an error in the position where the transport vehicle stops, and the front and rear error value is ±3mm, resulting in a misalignment between the lane track 19 and the vehicle-mounted stacker running track 7;

[0052] S3: When the transport vehicle stops, the travel drive motor 102 of the vehicle body travel mechanism 1 releases the brake to release the brake in the travel direction;

[0053] S4: Then the rail driving device 5 starts to work, the rail driving motor 501 of the rail driving device 5 drives the rotary push rod assembly 503 of the rail driving device 5, and the rotary push rod assembly 503 of the rail driving device 5 converts the rotary motion into a linear motion. The push rod in the rotary push rod assembly 503 of the rail driving device 5 extends forward, and the push rod of the rotary push rod assembly 503 of the rail driving device 5 drives the rail positioning rod 504 of the rail driving device 5 to extend forward. The rail positioning rod 504 of the rail driving device 5 is slowly inserted into the guide hole of the square hole positioning plate 173;

[0054] S5: Since the shape of the head of the rail-aligning positioning rod 504 of the rail-aligning driving device 5 is a square cone head, when the rail-aligning positioning rod 504 of the rail-aligning driving device 5 is extended, the ground rail-aligning positioning platform 17 will correct the position of the vehicle-mounted stacker running track 7, so as to drive the transport vehicle to perform micro-displacement alignment in the walking direction, so that the error value is reduced from ±3mm to ±0.5mm, and the alignment accuracy of the laneway track 19 and the vehicle-mounted stacker running track 7 is achieved within ±0.5mm, and then the stacker is driven from the vehicle-mounted stacker running track 7 into the laneway track 19 to work, thereby completing the switching of the stacker on different laneway tracks 19.

[0055] In summary, the present invention provides a transport vehicle for transferring stackers to switch between multiple lanes and a method for transferring the same. The vehicle body is assembled through a vehicle traveling mechanism 1, a vehicle body load-bearing frame 2, a vehicle body upper frame 3, a cargo guide rod 4, an on-board control cabinet 11, an on-board operating platform 12, etc. to form a set of electrically driven traveling vehicles. The ground vehicle takes power from the electric bus bar 14 to achieve horizontal movement in the front-to-back direction of the ground vehicle track 13. After loading into the stacker, the stacker can be transferred to different lanes to complete the work task. At the same time, in the process of the transport vehicle transferring the stacker to different lanes, the rail drive device 5 and the ground rail positioning platform 17 are mutually matched and operated, and the mechanism of the conical surface moving along the cross section is used to overcome the parking error, ensure the accuracy of the rail, and achieve the smooth round-trip movement of the stacker from the lane track 19 to the transport vehicle, the transport vehicle, and the lane track 19.
