[0029] The positioning pin 5 is at least provided with two, the positioning pin 5 successively includes mounting portion 51, pin joint portion 52 and positioning portion 53 from bottom to top, the positioning portion 53 is circular platform type, the mounting portion 51 and pin joint portion 52 are cylindrical, the diameter of mounting portion 51 is less than pin joint portion 52, and pin joint portion 52 provides limit when mounting portion 51 is inserted and connected in AGV 1;The positioning portion 53 is coaxial with pin joint portion 52 and is provided with same diameter, guarantees the stable insertion between positioning pin 5 and guide sleeve 4, ensures the relative position relationship between dolly chassis 2 and AGV 1 is accurate and faultless, to guarantee the whole mechanism can normally carry and stably run.

[0030] Further, the chassis 2 includes frame 21 and mounting plate 22, specifically, frame 21 adopts square frame 21, which is spliced by bar members, the mounting plate 22 is installed and arranged at the middle part of frame 21, and the guide sleeve 4 is installed on the mounting plate 22.

[0031] Further, the mounting plate 22 is square, the guide sleeve 4 is arranged on the mounting plate 22 along the diagonal line of the mounting plate 22, and the positioning pin 5 is arranged on the AGV 1 along the diagonal line of the AGV 1, to ensure that the connection between the AGV 1 and the dolly chassis 2 is more stable, and to reduce shaking and deviation during operation.

[0032] Further, the mounting plate 22 is provided with mounting holes, and the guide sleeve 4 is connected through the mounting holes and bolts. The guide sleeve 4 comprises a guide cylinder 41 and a mounting ring 42. The guide cylinder 41 is inserted into the mounting hole, and the mounting ring 42 is provided with a main screw hole 421. The outer side of the mounting hole is provided with a secondary screw hole, and the bolt is coaxially screwed into the main screw hole 421 and the secondary screw hole. The mounting is simple and fast, and the fastening effect of the bolt ensures the firm connection between the guide sleeve 4 and the mounting plate 22.

[0033] Further, four main screw holes 421 are circumferentially and equally spaced on each mounting ring 42, and four secondary screw holes are circumferentially and equally spaced on the outer periphery of each mounting hole.

[0034] Further, the connecting part between the pin joint 52 and the positioning part 53 is chamfered, which reduces stress concentration, improves the service life of the positioning pin 5, and also makes the cooperation between the positioning pin 5 and the guide sleeve 4 more smooth.

[0037] Further, the cooperating AGV 1 is provided with a lifting device, and the upper platform 11 is installed on the upper side of the lifting device. The positioning pin 5 is installed on the upper platform 11, which ensures that the AGV 1 can dive to the bottom side of the chassis 2.

[0038] Working principle: when in use, the trolley stops at a specified position, the AGV 1 automatically runs to the bottom of the trolley through the set route, when the AGV 1 runs to the specified position, the lifting device inside the AGV 1 starts to work, drives the upper platform 11 of the AGV 1 to rise, and then drives the positioning pin 5 to rise. The positioning pin 5 cooperates with the guide sleeve 4, continues to lift the upper platform 11 of the AGV 1 and the mounting plate 22 provided on the chassis 2 to contact, and then drives the frame 21 to rise. At this time, the shock-absorbing caster starts to release the spring compression amount, and when it reaches the preset height of the lifting inside the AGV 1, the shock-absorbing caster is still in contact with the ground, which ensures the support of the trolley and prevents the trolley from tipping over. At this time, the AGV 1 drives the trolley to run, and due to inertia, the trolley has a tendency to tip over. The larger and higher the trolley is, the greater the risk of tipping over. The cooperation between the positioning pin 5 and the guide sleeve 4 eliminates the tendency to tip over, and the shock-absorbing caster is also in contact with the ground to ensure that the trolley will not tip over, ensuring normal operation.
