At this time, the latch block will not contact the second slot wall, that is, there is a gap between the latch block and the first slot wall and the second slot wall. At this time, the AGV applies a driving force to the docking bracket through the push block, thereby pushing the section. When the AGV pulls the section, the latch block is in contact with the first slot wall. At this time, if the section moves up and down relative to the AGV, since the latch block is arranged on the AGV along the vertical sliding, the section and the docking bracket will follow the latch block to slide vertically relative to the AGV; when the AGV pushes the section, the push block is in contact with the docking bracket through the rolling assembly. At this time, if the section moves up and down relative to the AGV, the section and the docking bracket will roll vertically relative to the push block (i.e., AGV) through the rolling assembly. It can be seen that the present invention has an adaptive adjustment function. No matter when the AGV is pulling or pushing the section, even if the section moves up and down relative to the AGV, it will not generate an up and down drag force on the AGV. The AGV is always in contact with the ground and ensures the adhesion required for pulling and pushing under the action of its own weight. The AGV will never slip. In summary, the present invention can quickly dock the AGV and the section, and has a simple structure and easy operation.

[0037] like Figure 7-9 As shown in 13-16, the AGV docking traction lock of the present invention, wherein the lower end of the pin block 4 is provided with a first inclined surface 14, and the notch of the slot is provided with a second inclined surface 16 matching the first inclined surface 14. When the pin block 4 moves close to the slot, the pin block 4 can contact the second inclined surface 16 through the first inclined surface 14 and slide into the slot along the second inclined surface 16.

[0038] When the latch block 4 moves close to the slot, the latch block 4 can contact the second inclined surface 16 through the first inclined surface 14 and slide upward along the second inclined surface 16 until the latch block 4 comes to the slot just above the slot, and then under the action of its own weight, the latch block 4 moves downward and is inserted into the slot. In order to achieve the above purpose, when the latch block 4 moves close to the slot but has not yet been inserted into the slot, along the direction from the latch block 4 to the slot, the first inclined surface 14 and the second inclined surface 16 are gradually arranged to tilt upward, so that when the latch block 4 contacts the second inclined surface 16 through the first inclined surface 14 and continues to move close to the slot, the latch block 4 can slide upward along the second inclined surface 16 through the first inclined surface 14 until the latch comes to the slot just above the slot, and moves downward under the action of its own weight and is inserted into the slot.

[0039] like Figure 7 , 9 As shown in Figures 11, the AGV docking traction lock of the present invention, wherein the push blocks 51, 52 are provided with rolling components, and the rolling components include a plurality of rollers 15, the axis of each roller 15 is arranged in the horizontal direction, and the plurality of rollers 15 are arranged in sequence and spaced apart in the vertical direction on the push blocks 51, 52.

[0040] like Figure 1-7 As shown in , 9-10, 12-16, the present invention is a docking traction lock for AGV, wherein the latch blocks 4 are set to two, the two latch blocks 4 are arranged at intervals in the horizontal direction, the two latch blocks 4 are respectively fixed on two sliders 3, the two sliders 3 are respectively slidably connected on two slide rails 2 arranged vertically, the two slide rails 2 are used to be fixed on the AGV17, and the docking bracket 8 is provided with two slots corresponding to the two latch blocks 4 one by one, and the two latch blocks 4 are respectively inserted into their corresponding slots.

[0041] like Figure 12-16As shown, the docking traction lock for AGV of the present invention, wherein the two slots on the docking bracket 8 are respectively the first slot and the second slot, and the two latch blocks 4 are respectively inserted into the first slot and the second slot. The docking bracket 8 includes a support plate 13 arranged in the horizontal direction, and two first slot plates 9 and two second slot plates 11 arranged oppositely are fixedly provided on the support plate 13, and the first slot plates 9 and the second slot plates 11 are both arranged in the vertical direction, and the first slot plates 9 and the second slot plates 11 are both located on the same side of the support plate 13. First stoppers 10 are fixedly provided on opposite sides of the two first slot plates 9, respectively. The first stoppers 10 are located at one end of the first slot plate 9 away from the support plate 13. The space between the two first slot plates 9, the two first stoppers 10 and the support plate 13 constitutes a first slot. The sides of the two first stoppers 10 opposite to the support plate 13 are first slot walls 19 of the first slot. The sides of the support plate 13 opposite to the two first stoppers 10 are second slot walls 20 of the first slot. The upper end of the first stopper 10 is located at the notch of the first slot. The upper end of the first stopper 10 is provided with a second inclined surface 16. Second blocks 12 are fixedly provided on opposite sides of the two second slot plates 11, respectively. The second blocks 12 are located at one end of the second slot plate 11 away from the support plate 13. The space between the two second slot plates 11, the two second blocks 12 and the support plate 13 constitutes a second slot. The sides of the two second blocks 12 opposite to the support plate 13 are first slot walls 19 of the second slot. The sides of the support plate 13 opposite to the two second blocks 12 are second slot walls 20 of the second slot. The upper end of the second block 12 is located at the notch of the second slot, and the upper end of the second block 12 is provided with a second inclined surface 16.

[0042] For a pair of corresponding latch block 4 and slot, when the latch block 4 moves close to the slot, the first inclined surface 14 of the latch block 4 contacts the second inclined surface 16 at the upper ends of the two first stop blocks 10 / second stop blocks 12. As the latch block 4 continues to move close to the latch, the latch block 4 gradually slides upward along the second inclined surface 16 through the first inclined surface 14 until the latch block 4 comes to the top of the notch of the first slot / second slot, and then moves downward under the action of its own gravity and inserts into the first slot / second slot. By setting the first inclined surface 14 and the second inclined surface 16, the latch block 4 can be automatically inserted into the slot when the AGV 17 and the section 18 are docked, without manual operation.

[0043] like Figure 1-7As shown in , 9 and 10, the AGV docking traction lock of the present invention, wherein the push blocks 51 and 52 are provided in pairs, the two push blocks 51 and 52 are located between the two latch blocks 4, the two push blocks 51 and 52 are respectively the first push block 51 and the second push block 52, the first push block 51 is arranged corresponding to the first slot plate 9 close to the second slot, and the second push block 52 is arranged corresponding to the second slot plate 11 close to the first slot. Figure 3 As shown, when the two latch blocks 4 are in contact with the first slot walls 19 of their respective slots, there is a gap a between the first push block 51 and the corresponding first slot plate 9 and between the second push block 52 and the corresponding second slot plate 11. Figure 4 As shown, when the first push block 51 abuts against the corresponding first slot plate 9 through the rolling assembly thereon and the second push block 52 abuts against the corresponding second slot plate 11 through the rolling assembly thereon, there are gaps between the two latch blocks 4 and the first slot walls 19 and the second slot walls 20 of their respective corresponding slots, that is, there is a gap b between each latch block 4 and the first slot wall 19 of the corresponding slot, and there is a gap c between each latch block 4 and the second slot wall 20 of the corresponding slot.

[0044] When the first push block 51 abuts against the corresponding first slot plate 9, in order to increase the contact area between the two, the first stopper 51 and the side of the first slot plate 9 away from the support plate 13 can be set to be flush with each other, and together serve as the contact surface with the first push block 51, so as to facilitate the first push block 51 to push the docking bracket 8, that is, to facilitate the pushing section 18. Similarly, when the second push block 52 abuts against the corresponding second slot plate 11, in order to increase the contact area between the two, the second stopper 12 and the side of the second slot plate 11 away from the support plate 13 can be set to be flush with each other, and together serve as the contact surface with the second push block 52, so as to facilitate the second push block 52 to push the docking bracket 8, that is, to facilitate the pushing section 18.

[0045] like Figure 1 , 2 As shown in , 5, 6, 7, 9, and 10, the AGV docking traction lock of the present invention has an upper limit block 1 above each of the latch blocks 4, and the upper limit block 1 is used to be fixed on the AGV 17. Figure 1 , 6As shown in FIG. 10 , a lower limit block 7 is provided below each of the latch blocks 4, and the lower limit block 7 is used to be fixed on the AGV 17. The upper limit block 1 and the lower limit block 7 both limit the latch block 4. When the latch block 4 slides upward along the slide rail 2 to the upper end of the slide rail 2 through the slider 3, the latch block 4 abuts against the upper limit block 1. Conversely, when the latch block 4 slides downward along the slide rail 2 to the lower end of the slide rail 2 through the slider 3, the latch block 4 abuts against the lower limit block 7. In this way, under the limiting action of the upper limit block 1 and the lower limit block 7, the latch block 4 will not slip off the slide rail 2.

[0046] like Figure 1 , 5 As shown in 6-10, the docking traction lock for AGV of the present invention, wherein a handle 6 is fixedly connected between the two latch blocks 4. The handle 6 includes a straight rod arranged in the horizontal direction and a U-shaped rod arranged in the vertical direction, and the two ends of the straight rod are respectively fixedly connected to the two latch blocks 4, and the U-shaped rod is located above the straight rod, and the two ends of the U-shaped rod are fixedly arranged on the straight rod. The purpose of setting the handle 6 is that the staff can use the handle 6 to simultaneously operate the two latch blocks 4 to slide up or down along the slide rail 2.

[0047] like Figure 17-20 As shown, when the docking and traction lock for AGV of the present invention is used, the latch block 4 is first pulled out from the slot, that is, the latch block 4 is separated from the docking bracket 8, and then the latch block 4 is vertically slid on the AGV 17 through the slider 3 and the slide rail 2, and the push blocks 51 and 52 are fixed on the AGV 17, and the docking bracket 8 is fixed on the section 18. The section 18 is a structure pulled or pushed by the AGV 17, such as a suspended air cushion, and the equipment to be transported is placed on the suspended air cushion, and then the docking bracket 8 is fixed on the suspended air cushion. After the latch block 4 is inserted into the slot, the AGV 17 can pull the suspended air cushion through the present invention to achieve the purpose of transporting the equipment.

[0048] When AGV17 is docking with section 18, section 18 remains stationary, and then AGV17 is moved to allow the latch block 4 on AGV17 to gradually approach the slot on the docking bracket 8 of section 18. When the latch block 4 reaches the slot, the latch block 4 is inserted into the slot under the action of the first inclined surface 14 and the second inclined surface 16 to complete the automatic docking. When AGV17 pulls section 18, the latch block 4 abuts against the first slot wall 19 of the slot. At this time, there is a gap between the push blocks 51, 52 and the docking bracket 8, that is, the push blocks 51, 52 will not apply force to the docking bracket 8. At this time, AGV17 applies a pulling force to the first slot wall 19 of the slot through the latch block 4, thereby pulling section 18. When AGV17 pushes section 18, the latch block 4 disengages from the first slot wall 19, and the push blocks 51 and 52 abut against the docking bracket 8 (that is, the first push block 51 abuts against the corresponding first slot plate 9 through the rolling assembly on itself, and the second push block 52 abuts against the corresponding second slot plate 11 through the rolling assembly on itself). At this time, the latch block 4 will not contact the second slot wall 20, that is, there is a gap between the latch block 4 and the first slot wall 19 and the second slot wall 20. At this time, AGV17 applies a driving force to the docking bracket 8 through the push blocks 51 and 52, thereby realizing the pushing of section 18. When AGV17 pulls section 18, the latch block 4 abuts against the first groove wall 19. At this time, if section 18 moves up and down relative to AGV17, since the latch block 4 is vertically slidably arranged on AGV17, the section 18 and the docking bracket 8 will follow the latch block 4 to slide vertically relative to AGV17; when AGV17 pushes section 18, the push blocks 51 and 52 abut against the docking bracket 8 through the rolling assembly. At this time, if section 18 moves up and down relative to AGV17, the section 18 and the docking bracket 8 will roll vertically relative to the push blocks 51 and 52 (i.e., AGV17) through the rolling assembly. It can be seen that the present invention has an adaptive adjustment function. No matter when AGV17 pulls or pushes segment 18, even if segment 18 moves up and down relative to AGV17, it will not generate up and down drag force on AGV17. AGV17 is always in contact with the ground and ensures the adhesion required for pulling and pushing under the action of its own weight. AGV17 will never slip. In summary, the present invention can quickly dock AGV17 and segment 18, and has a simple structure and easy operation.

[0049] like Fig.13 As shown, for each slot, the two opposite sides of the two first slot plates 9 / the second slot plates 11 are respectively the third slot wall 21 and the fourth slot wall 22 of the first slot / the second slot. Figure 3As shown, when AGV17 pulls section 18, latch block 4 abuts against first slot wall 19 of slot. When AGV17 pulls section 18 forward, latch block 4 will not apply pulling force to third slot wall 21 and fourth slot wall 22 of slot. However, when AGV17 pulls section 18 to turn, latch block 4 may abut against third slot wall 21 or fourth slot wall 22 and apply pulling force to it. At this time, if section 18 moves up and down relative to AGV17, section 18 and docking bracket 8 will still follow latch block 4 to slide vertically relative to AGV17. Figure 4 As shown, when AGV17 pushes section 18, push blocks 51, 52 abut against docking bracket 8, and latch block 4 does not contact first slot wall 19 and second slot wall 20 of the slot. However, when AGV17 pushes section 18 to turn, latch block 4 may abut against third slot wall 21 or fourth slot wall 22 of the slot and apply thrust thereto. At this time, if section 18 moves up and down relative to AGV17, section 18 and docking bracket 8 roll vertically relative to push blocks 51, 52 (i.e., AGV17) through rolling assembly, and section 18 and docking bracket 8 slide vertically relative to AGV17 following latch block 4. It can be seen from this that no matter whether AGV17 pulls / pushes segment 18 for forward motion or turning motion, even if segment 18 moves up and down relative to AGV17, it will not generate up and down drag force on AGV17, so that AGV17 is always in contact with the ground and ensures the adhesion required for pulling and pushing under the action of its own weight, and no slipping will occur.

[0050] When it is necessary to separate the latch block 4 from the slot of the docking bracket 8, move AGV17 so that AGV17 and section 18 are basically in a forward docking state, that is, the latch block 4 is not in contact with the third slot wall 21 and the fourth slot wall 22 of the slot, and then move AGV17 closer to the docking bracket 8 to allow the push blocks 51 and 52 to abut against the docking bracket 8. At this time, there is a gap between the latch block 4 and the first slot wall 19 and the second slot wall 20 of the slot. At this time, the latch block 4 will not contact any slot wall of the slot, that is, the slot will not hinder the latch block 4 from sliding along the slide rail 2. At this time, the staff pulls the latch block 4 upward through the handle 6, so that the latch block 4 slides upward along the slide rail 2 until the latch block 4 slides out of the slot, and then moves AGV17 away from the docking bracket 8 to complete the separation of the latch block 4 from the docking bracket 8. Finally, the staff releases the handle 6, and under the action of its own gravity, the latch block 4 abuts against the lower limit block 7.
