Multiple processing stations can be set up on the outside of the conveyor to assemble, test, repair, package, and unload the transported materials. The repair station on the conveyor belongs to the branch line and is often used to load and unload materials. Defective materials will be transferred to the roller trolley and then taken for maintenance. After the maintenance is completed, the materials will be pulled to the repair station again and moved to the main line through the repair station.

[0003] If the width of the conveyor transfer part is greater than the width of the roller trolley, there is a risk that the material will be stuck at the docking end of the roller trolley when the material is transferred from the conveyor to the roller trolley; if the width of the conveyor transfer part is less than the width of the roller trolley, there is a risk that the material will be stuck at the docking end of the conveyor when the material is transferred from the roller trolley to the conveyor; if the width of the conveyor transfer part is the same as the width of the docking end of the roller trolley, the staff will need to accurately dock the ends of the two during the material transfer process, and this docking method is difficult to achieve accurate docking manually;

[0034] It also includes: a docking unit, which is used for docking the ends of the branch conveyor line frame 1 and the conveyor trolley frame 3, and the docking units are distributed at both ends of the branch conveyor line frame 1;

[0035] The driving unit is used to trigger the docking unit to connect the ends of the branch conveyor line frame 1 and the conveying cart frame 3. The driving unit is located at the bottom of the branch conveyor line frame 1.

[0036] The position of the branch conveyor line frame 1 is fixed, and two first docking blocks 7 and two second docking blocks 8 are fixedly arranged on one end surface of the main conveyor line frame 5 close to the branch conveyor line frame 1, and one end surface of the conveying trolley frame 3 close to the branch conveyor line frame 1, respectively. The first docking block 7 and the second docking block 8 are fixedly assembled with the main conveyor line frame 5 and the conveying trolley frame 3, respectively, and the width of the branch conveyor line frame 1 is consistent with the width of the conveying trolley frame 3;

[0037] The docking unit includes closed and unfolded states:

[0038] In the closed state, the docking unit clamps and restricts the first docking block 7 and the second docking block 8 at the same time;

[0039] In the unfolded state, the docking unit does not restrict the first docking block 7 and the second docking block 8. The branch conveyor line frame 1 is used to carry the equipment or materials to be transferred, while the conveyor trolley frame 3 and the second roller 4 are used to transfer the equipment or materials. The bottom of the conveyor trolley frame 3 is equipped with universal wheels.

[0040] The docking unit includes a connecting plate 17 fixedly mounted on both ends of the branch conveyor line frame 1, and two symmetrically distributed limit plates 18 are fixedly arranged on one end face of the connecting plate 17 away from the branch conveyor line frame 1, and the upper end faces of the connecting plate 17 and the limit plate 18 are covered with a stopper 21, and the stopper 21 and the branch conveyor line frame 1 are fixedly assembled, and one end face of each limit plate 18 away from the stopper 21 is elastically hingedly assembled with a movable plate 19, and the two movable plates 19 assembled on the outside of the same connecting plate 17 are elastically deflected in opposite directions, the limit plate 18 and the movable plate 19 are elastically hingedly assembled by a latch and a torsion spring, and the two movable plates 19 are in an unfolded state when not under force.

[0041] The limiting plate 18 is of the same thickness as the movable plate 19, and an assembly cavity is formed between the two limiting plates 18 on the same connecting plate 17. The thickness of the second docking block 8 is also the same as that of the first docking block 7, and both the first docking block 7 and the second docking block 8 are slidably assembled with the assembly cavity. When the two movable plates 19 are closed, the first docking block 7 and the second docking block 8 can be clamped and limited.

[0042] The bottom of the branch conveyor frame 1 is fixedly provided with four slide bars 11 distributed in a matrix, the bottom of the slide bar 11 is fixedly sleeved with a clamping ring 13, the outer surface of the clamping ring 13 is slidably sleeved with a sleeve 12, and a spring 14 is fixedly provided between the end of the clamping ring 13 away from the slide bar 11 and the sleeve 12, the driving unit includes a lifting cylinder 9 located at the center of the four sleeves 12, the output end of the lifting cylinder 9 is facing upward, and the output end of the lifting cylinder 9 is fixedly sleeved with an assembly plate 10, each movable plate 19 is provided with a roller 16 on the side away from the assembly cavity, the interior of the roller 16 is sleeved with a right-angle curved rod 15, and the other end of the right-angle curved rod 15 It is fixedly installed in the assembly plate 10, and a supporting plate 20 is fixedly arranged on the outer side of the bottom of the movable plate 19, and the supporting plate 20 is distributed on the side of the movable plate 19 away from the assembly cavity. A fixing block 31 is also fixedly arranged on the side of the limiting plate 18 close to the roller 16. The fixing block 31 is located above the roller 16. The positions of the main conveyor frame 5, the sleeve 12, and the lifting cylinder 9 are relatively fixed. The conveying end of the lifting cylinder 9 supports the fixing block 31 through the assembly plate 10, the right-angle curved rod 15 and the roller 16, that is, it supports the branch conveyor frame 1, and the assembly of the slide bar 11 and the sleeve 12 is to limit the position of the branch conveyor frame 1.

[0043] The end face of the limiting plate 18 away from the assembly cavity is tangent to the outer surface of the roller 16. When the right-angle curved rod 15 moves the roller 16 downward, the roller 16 squeezes the movable plate 19, so that the movable plate 19 and the limiting plate 18 are in the same vertical plane.

[0044] When the spring 14 is not compressed, the heights of the branch conveyor line frame 1 and the main conveyor line frame 5 are consistent, and the height of the conveying cart frame 3 is lower than the height of the branch conveyor line frame 1, that is, the support of the fixed block 31 and the branch conveyor line frame 1 by the lifting cylinder 9, the right-angle curved rod 15 and the roller 16 can make the upper end surfaces of the branch conveyor line frame 1 and the main conveyor line frame 5 flush.

[0045] Working principle: When the staff pushes the conveyor trolley frame 3 to dock with the end of the branch conveyor line frame 1, since the movable plate 19 is in an unfolded state, when the second docking block 8 extends between the two movable plates 19, a larger error can be accepted, that is, there is no need to perform very precise docking, making the initial docking more convenient;

[0046] When the two second docking blocks 8 are both against the end surface of the connecting plate 17, the staff holds the handle of the conveyor trolley frame 3 and triggers the lifting cylinder 9 to move the lifting cylinder 9 downward with the right-angle curved rod 15 and the roller 16 through the assembly plate 10. Due to the weight of the branch conveyor frame 1 and the materials or equipment carried above it, the spring 14 can be compressed to make the branch conveyor frame 1 follow the assembly plate 10 to fall. When the elastic force generated by the compression of the spring 14 can bear the gravity of the branch conveyor frame 1 and the materials above it, the position of the branch conveyor frame 1 is not Changes occur again. At this time, the assembly plate 10 continues to move downward with the right-angle curved rod 15 and the roller 16, which can squeeze the movable plate 19, allowing the two movable plates 19 to slowly close, and clamp and adjust the position of the second docking block 8 located between the two movable plates 19, so that the second docking block 8 and the assembly cavity can be effectively matched. When the movable plate 19 completes the clamping of the second docking block 8, the end of the conveying trolley frame 3 and the end of the branch conveyor line frame 1 are accurately docked, and there is no protruding structure on the conveying path from the first roller 2 to the second roller 4 to block the material or equipment;

[0047] Moreover, when the movable plate 19 is completely closed, the right-angle curved rod 15 continues to move downward with the roller 16, and the roller 16 can lower the entire branch conveyor line frame 1 through the action of the supporting plate 20, so that the upper end surface of the branch conveyor line frame 1 is coplanar with the upper end surface of the conveyor trolley frame 3, thereby ensuring the stable transportation of materials or equipment between the branch conveyor line frame 1 and the conveyor trolley frame 3.

[0048] Through the above-mentioned docking method, it is possible to achieve precise docking between the end of the conveying cart frame 3 and the end of the branch conveyor line frame 1 without the need for the staff to manually and tediously dock them. Only the lifting cylinder 9 needs to be triggered to achieve precise docking processing, and the docking efficiency is better, thereby improving the convenience of transportation, and enabling one staff member to complete the transportation of equipment or materials.

[0049] It is worth noting that the control button for controlling the operation of the lifting cylinder 9 is installed on the ground, allowing the staff to control it with their feet; or there is a vertical pole on the outside of the branch conveyor line frame 1, and the control button for controlling the lifting cylinder 9 is installed on the vertical pole, which is also convenient for the staff to adjust the lifting cylinder 9.

[0050] Example 2: Please refer to Figure 8 This embodiment is a further explanation of the first embodiment. A positioning pin 30 is fixedly provided at the bottom of each stopper 21, and a positioning slot 29 is opened at the top of each second docking block 8. The downwardly distributed positioning pins 30 are slidably assembled with the positioning slots 29, and the bottom of the positioning pins 30 is dome-shaped. When the second docking block 8 slides upward inside the assembly cavity, the second docking block 8 can be locked inside the assembly cavity through the cooperation of the positioning pins 30 and the positioning slots 29, thereby further ensuring the stability of the connection between the branch conveyor line frame 1 and the conveying cart frame 3.

[0051] In this embodiment: when the branch conveyor line frame 1 moves downward as a whole, the second docking block 8 slides toward the stop block 21 inside the assembly cavity, allowing the positioning pin 30 to be embedded in the positioning slot 29, so that the position of the branch conveyor line frame 1 and the conveyor trolley frame 3 can be defined. At this time, the staff does not need to hold the conveyor trolley frame 3, which makes it easier for the staff to transfer materials or equipment on the branch conveyor line frame 1 to the conveyor trolley frame 3.

[0052] Example 3: Please refer to Figure 6 and Figure 7 , this embodiment is a further explanation of the first embodiment, the second docking block 8 is hollow, the second docking block 8 is rotatably provided with a second rotating column 23 inside, and the outer surface of the second rotating column 23 is fixedly sleeved with a second gear 27, and the end of one of the second roller shafts 4 close to the second rotating column 23 is fixedly sleeved with a third gear 28, and the third gear 28 is movably meshed with the second gear 27, and the branch conveyor line frame 1 is rotatably provided with a first rotating column 22 at one end close to the conveying trolley frame 3, the outer surface of the first rotating column 22 and the outer surface of the end of one of the first roller shafts 2 close to the first rotating column 22 are fixedly sleeved with a synchronous gear 24, and a toothed belt 25 is installed between the two synchronous gears 24 on the same side, and the outer surface of the first rotating column 22 is also fixedly sleeved with a first gear 26 meshing with the second gear 27, that is, when the second docking block 8 is fully assembled with the assembly cavity, the second gear 27 can be meshed with the first gear 26.

[0053] An empty slot is opened inside the connecting plate 17, and the first gear 26 extends out of the empty slot. When the second docking block 8 slides from bottom to top inside the assembly cavity, it will not be hindered by the first gear 26. The second gear 27 extends out of the second docking block 8 near one end of the branch conveyor line frame 1, and the second gear 27 also extends into the interior of the empty slot.

[0054] In this embodiment: when the second docking block 8 is fully matched with the assembly cavity, the second gear 27 can mesh with the first gear 26. When the motor drives the first roller 2 to rotate, the first rotating column 22 and the first gear 26 can rotate synchronously in the same direction through the action of the synchronous gear 24 and the toothed belt 25. When the first gear 26 drives the third gear 28 to rotate through the second gear 27, the second roller 4 and the first roller 2 can also rotate in the same direction, so that the materials or equipment above the branch conveyor line frame 1 and the conveying cart frame 3 can be automatically transferred.
