[0002] AGV carts usually refer to transport vehicles equipped with automatic guidance devices such as electromagnetic or optical devices, which can travel along a specified guidance path and have safety protection and various transfer functions. They are transport vehicles that do not require a driver in industrial applications and use rechargeable batteries as their power source. Their routes and behaviors can generally be controlled by computers, or their routes can be established using electromagnetic tracks that are attached to the floor. The unmanned transport vehicle relies on the information brought by the electromagnetic tracks to move and act.

A front and rear telescopic mechanism for telescoping the clamping seat forward and backward and a left and right telescopic mechanism for telescoping the clamping seat left and right are arranged on the vehicle body. The clamping seats arranged on both sides of the placing table cooperate with the front and rear telescopic mechanism for telescoping the clamping seat forward and backward and the left and right telescopic mechanism for telescoping the clamping seat left and right to effectively realize the restraint of the plate placing rack, thereby ensuring its stability during movement.

At this time, the electromagnet module 415 is magnetically fitted with the magnetic ring 436, and the third transmission gear 434 is disengaged from the third meshing tooth 334. When the electric control module 25 controls the electric control switch to be turned off, the electromagnet is in a power-off state.

At this time, the third transmission gear 434 is transmission-connected with the third meshing tooth 334.

[0065] Working principle: When the automatic guided vehicle 1 automatically moves to the position of the material 8, the first driving module 21 controls the rotation of the 360-degree steering mechanism 2 through the first transmission gear 27, which is used to adjust the horizontal positions of the first adjustment mechanism 4 and the second adjustment mechanism 5 according to the position of the material 8.

[0066] Reference Figure 1When the material 8 is a curved pipe or a curved rod located on the material rack, the first telescopic member 314 is first used to control the second driving module 311, the driving rod 312 and the driving gear 313 to move until the first meshing tooth 321 is connected to the driving gear 313 by transmission, and then the electromagnet module 415 is controlled to be energized. After the electromagnet module 415 is energized, it is magnetically attached to the magnetic ring 436. Since the first key strip 316 is separated from the first key slot 332 at this time, when the second driving module 311 controls the ring through the driving rod 312, the driving gear 313 and the first meshing tooth 321, When the annular shell 32 rotates, the rotating annular shell 32 controls the first adjusting mechanism 4 and the second adjusting mechanism 5 to rotate in the direction of approaching or moving away from each other with the fixed shaft 23 as the axis through the second meshing teeth 322 and the second transmission gear 414. Since the third transmission gear 434 is disengaged from the third meshing teeth 334 at this time, the third transmission gear 434 will not rotate on its own, so that the angle between the first anti-slipping mechanism 6 and the second anti-slipping mechanism 7 can be adjusted according to the curvature of the bent pipe or the bent rod, and then the second telescopic member 421 is used to control the telescopic plate 423 to move along the straight line. The guide rail 411 makes a linear motion to adjust the positions of the first anti-slip mechanism 6 and the second anti-slip mechanism 7 according to the curvature of the curved tube or the curved rod, until the curved tube or the curved rod is located between the two first anti-slip plates 611 and stops. Then, the first telescopic member 314 is used to control the driving gear 313 to disengage from the first meshing tooth 321, and the electromagnet module 415 is powered off. Since the first key bar 316 is located in the first key slot 332 at this time, when the second driving module 311 controls the hollow worm 331 through the driving rod 312, the first key bar 316 and the first key slot 332, During rotation, the rotating hollow worm 331 controls the rotation of the worm wheel 333. When the elastic force of the return spring 416 drives the third transmission gear 434 to fit with the limiting pad 435, the third transmission gear 434 is connected with the third meshing tooth 334. Therefore, the rotating worm wheel 333 controls the two first anti-slip plates 611 to rotate towards each other with the rotating shaft 614 as the axis through the third meshing tooth 334 and the third transmission gear 434. The two first anti-slip plates 611 can prevent the bent pipes or bent rods from falling off, thereby realizing the function of transporting bent pipes or bent rods with different curvatures.

[0067] Reference Fig.23When the material 8 is a columnar member, take a columnar member placed vertically on the ground as an example. First, use the above operation method to control the first adjustment mechanism 4 and the second adjustment mechanism 5 to adjust to a horizontal state with the fixed axis 23 as the axis. When the columnar member presents a certain inclination angle with the ground, adjust the angles of the first adjustment mechanism 4 and the second adjustment mechanism 5 according to the inclination angle, and then use the second telescopic member 421 to control the first anti-slip mechanism 6 and the second anti-slip mechanism 7 to move horizontally until the columnar member is located between the two first anti-slip plates 611 and stops.
