The four groups of base moving components are arranged on the lower end surface of the base 1. The fork assembly is arranged on the base 1. The fork forward pushing assembly is arranged on the base 1 and is connected to the fork assembly. The fork lifting assembly is arranged on the base 1 and is connected to the fork assembly. The fork assembly includes a fork frame 2 and two fork forward pushing seats 3. The two fork forward pushing seats 3 are respectively connected to both ends of the fork frame 2. The fork frame 2 is arranged on the base 1 and is connected to the fork forward pushing assembly. A fork lifting assembly is arranged on the fork frame 2, and a lifting fork 4 is arranged on each of the two fork forward pushing seats 3. The lifting fork 4 is connected to the fork lifting assembly.

[0026] Specifically, the fork forward pushing assembly includes a first main shaft 5. The first main shaft 5 is rotatably connected to the fork frame 2. A first sprocket 6 is connected to each end of the first main shaft 5, and a second sprocket 7 is connected to the middle. A first chain 8 is connected to each end of the upper end surface of the base 1. The first sprocket 6 meshes with the first chain 8. A second chain 9 is connected to the second sprocket 7. The other end of the second chain 9 is connected to a third sprocket 10. The third sprocket 10 is connected to the output end of a first motor 11. The first motor 11 is connected to the fork frame 2.

[0027] Specifically, the first motor 11 drives the third sprocket 10 to drive the second sprocket 7 to rotate through the second chain 9. The rotation of the second sprocket 7 drives the first main shaft 5 to rotate. The rotation of the first main shaft 5 drives the first sprockets 6 connected to both ends to rotate. The rotation of the first sprockets 6 and the action of the meshed first chain 8 can make the fork frame 2, the two fork forward pushing seats 3, and the lifting fork 4 move forward.

[0028] Specifically, the fork lifting assembly includes a second main shaft 12. The second main shaft 12 is rotatably connected to the fork frame 2. A fourth sprocket 13 is connected to each end of the second main shaft 12. A fifth sprocket 14 is rotatably connected to each of the two fork forward pushing seats 3. One end of a third chain 15 is connected to the fourth sprocket 13, and the other end is connected to the fifth sprocket 14. A fixing block 16 is connected to the third chain 15. The other end of the fixing block 16 is connected to the lifting fork 4. A sixth sprocket 17 is connected to the middle of the second main shaft 12. A fourth chain 18 is connected to the sixth sprocket 17. The other end of the fourth chain 18 is connected to a seventh sprocket 19. The seventh sprocket 19 is connected to the output end of a second motor 20. The second motor 20 is connected to the fork frame 2. A limiting slide rail 31 is connected to the fork frame 2. A slider 32 is slidably connected to the limiting slide rail 31. The slider 32 is connected to the lifting fork 4.

[0029] Specifically, the second motor 20 drives the seventh sprocket 19 to rotate. The rotation of the seventh sprocket 19 drives the sixth sprocket 17 to rotate through the fourth chain 18. The rotation of the sixth sprocket 17 drives the second main shaft 12 to rotate. The rotation of the second main shaft 12 drives the two fourth sprockets 13 to rotate. The rotation of the fourth sprockets 13 drives the connected third chain 15 to rotate. The rotation of the third chain 15 drives the connected fixed block 16 to move upward. The upward movement of the fixed block 16 drives the lifting fork 4 to move upward, thereby driving the goods carried by the lifting fork 4 to rise.

[0030] Specifically, the base moving assembly includes a moving wheel set 21, a reduction gear set 22, and a third motor 23. The output end of the third motor 23 is connected to the reduction gear set 22, and the other end of the reduction gear set 22 is connected to the moving wheel set 21. The third motor 23 drives the reduction gear set 22 to move, thereby driving the moving wheel set 21 to turn, enabling the base 1 to move in different directions.

[0031] Specifically, a first auxiliary wheel 24 is connected to the rear end of the fork front push seat 3, and a second auxiliary wheel 25 is connected to the front end. A lifting assembly is provided on the fork front push seat 3; the first auxiliary wheel 24 is in rolling connection with the bottom plate of the base 1. The lifting assembly includes a lifting seat 26. One end of the lifting seat 26 is connected to the second auxiliary wheel 25. The lifting seat 26 is rotatably connected to the front end of the fork front push seat 3. A spring 27 is connected to the rear end of the lifting seat 26, and the upper end of the spring 27 is connected to the fork front push seat 3. A cylinder 28 is connected to the fork front push seat 3. The output end of the cylinder 28 is connected to an extension rod 29, and the other end of the extension rod 29 is connected to an inclined block 30, which extends into the lifting seat 26.

[0032] Specifically, when the fork front push seat 3 extends out of the base 1, the second auxiliary wheel 25 needs to contact the ground. At this time, the output end of the cylinder 28 extends to push the inclined block 30 to move forward and press down the lifting seat 26, causing the front end of the lifting seat 26 to flip downward, so that the second auxiliary wheel 25 contacts the ground; when the base 1 needs to move horizontally, the output end of the cylinder 28 retracts to drive the inclined block 30 to move behind the lifting seat 26 and no longer press down the lifting seat 26. At this time, the spring 27 resets to push the rear end of the lifting seat 26, causing the front end of the lifting seat 26 to flip upward, so that the second auxiliary wheel 25 does not contact the ground.

[0033] When inserting and picking up goods in a narrow aisle, the base moving assembly drives the base 1 to move horizontally to the rear of the goods. The fork pushing assembly pushes the fork frame 2, two fork pushing seats 3 and the lifting fork 4 forward to insert the goods. When the fork pushing seat 3 moves forward out of the base 1, the output end of the cylinder 28 extends to push the inclined block 30 to move forward and press down the lifting seat 26, so that the front end of the lifting seat 26 turns downward, making the second auxiliary wheel 25 contact the ground; the fork lifting assembly drives the lifting fork 4 to move upward to lift the goods, and then the fork pushing assembly drives the fork frame 2, two fork pushing seats 3 and the lifting fork 4 to move backward, so that the goods move above the base 1. The fork lifting assembly descends to place the goods on the upper end face of the base 1. When the fork pushing seat 3 retracts, the output end of the cylinder 28 retracts to drive the inclined block 30 to move to the rear of the lifting seat 26 and no longer press down the lifting seat 26. At this time, the spring 27 resets to push the rear end of the lifting seat 26, so that the front end of the lifting seat 26 turns upward, making the second auxiliary wheel 25 not contact the ground; then the base moving assembly drives the base 1 to move horizontally to the position where the goods are placed. The fork lifting assembly drives the lifting fork 4 to move upward to lift the goods, and then the fork pushing assembly pushes the fork frame 2, two fork pushing seats 3 and the lifting fork 4 forward to place the goods in place. The fork lifting assembly descends to place the goods in place. After that, the fork frame 2, two fork pushing seats 3 and the lifting fork 4 retract. The above is to complete the handling of a piece of goods.

[0034] This narrow-aisle inserting and carrying forklift maximally compresses the width dimension by setting a base moving assembly, a fork assembly, a fork pushing assembly and a fork lifting assembly, and can realize passing through a narrow aisle; at the same time, the base moving assembly can be carried to realize moving in any direction with a small operation radius, thus ensuring the flexibility of insertion and picking.
