[0029] See also Figure 1-Figure 5 As shown, a forklift gantry automatic shape correction device comprises:

[0030] A support frame 1, the support frame 1 comprises a double-layer support and two transverse steel beams, the two transverse steel beams are fixedly mounted on both sides of the top surface of the support, and a plurality of power rollers 5 are horizontally inserted on the inner walls of the opposite sides of the two transverse steel beams;

[0033] The laser detection fixture 6 is fixedly mounted on one side of the top surface of the bracket facing the shaping mechanism 3 .

[0034] As can be seen from the above, after the device is connected to the PLC controller, the staff controls the operation of the device through the PLC controller, places the forklift gantry at the starting end of the power roller 5, and then starts the driving mechanism 2 to drive the movement of the gantry. When the gantry moves to the position of the shaping mechanism 3, it is detected by the laser detection fixture 6 to check whether the gantry width deviation value is within the set allowable range, automatically determine the shaping amount and shaping direction, and then perform shaping through the shaping mechanism 3 to complete the shaping work of the forklift gantry, and then continue to drive the gantry to move and move the gantry out of the device.

[0035] Specifically, the driving mechanism 2 includes a conveying motor 201, a sprocket conveyor line body 202 and a servo module 203. The conveying motor 201 is fixedly installed on the bottom layer of the bracket near one side by bolts, and the servo module 203 is fixedly installed on the top layer of the bracket near the middle by bolts. One end of the sprocket conveyor line body 202 is connected to the conveying motor 201, and the other end of the sprocket conveyor line body 202 is connected to the power roller 5 located at one end. The servo module 203 is connected to one end of the conveying motor 201.

[0036] As can be seen from the above, the conveying motor 201 is started, and the power roller 5 is driven to rotate through the sprocket transmission line body 202, thereby driving the movement of the forklift gantry. After the servo module 203 acts on the conveying motor 201, it is convenient to adjust the movement direction and movement speed of the gantry.

After the servo module 203 acts on the conveying motor 201, it is convenient to adjust the movement direction and speed of the gantry.
