[0032] This application provides a trolley, such as Figure 1 As shown, the trolley 100 includes a vehicle body 110 , on which abutment blocks 140 and latch holes 150 are provided.
[0033] The present application provides a trailer mechanism 700 for transporting a trolley, such as Figures 1 to 3 As shown, the trailer mechanism 700 includes a trailer body 710 and a trailer slide rail 720. The trailer slide rail 720 is arranged on the trailer body 710 and is used to slide with the trolley 100. The trailer body 710 can drive the trailer slide rail 720 to move to a preset position so that the trailer slide rail 720 and the guide rail to be spliced can be spliced. The trolley 100 is configured to slide and switch between the trailer slide rail 720 and the guide rail to be spliced after the trailer slide rail 720 and the guide rail to be spliced are spliced.
[0034] The trailer mechanism 700 is provided with a trailer rail 720 on the trailer body 710 of the trailer mechanism 700. When the trailer body 710 can drive the trailer rail 720 to move to a preset position, the trailer rail 720 can be spliced with the guide rail to be spliced. The trailer rail 720 is used to slide with the trolley 100, that is, the trolley 100 can slide on the trailer rail 720. After the trailer rail 720 and the guide rail to be spliced are spliced, the trolley 100 slides and switches between the trailer rail 720 and the guide rail to be spliced. When the trolley needs to be taken offline, the trolley 100 can slide into the trailer rail 720 through the guide rail to be spliced, and then the trolley 100 is driven to move by the trailer body 710, thereby completing the offline process of the trolley 100. When the trolley 100 needs to go online, the trolley 100 is first set on the trailer slide 7207, and the trailer body 710 drives the trolley 100 to move, and when the trailer body 710 moves to the preset position, the trailer slide 720 and the guide rail to be spliced are spliced. At this time, the trolley 100 can also slide into the guide rail to be spliced through the trailer slide 720, thereby completing the online process of the trolley 100. The trailer mechanism 700 provided in this application, when the trailer body 710 moves to the preset position, the trailer slide 720 can be spliced with the guide rail to be spliced, and the trolley 100 can slide and switch between the trailer slide 720 and the guide rail to be spliced, thereby completing the online or offline process, and no additional work is required to realize the online and offline of the trolley 100, thereby improving the online and offline efficiency of the trolley 100.
[0035] It should be noted that the alignment of the trailer slide rail 720 with the guide rail to be spliced means that the end of the trailer slide rail 720 is spliced with the end of the guide rail to be spliced.
[0036] It should be noted that when the trolley 100 slides and switches between the trailer rail 720 and the guide rail to be spliced, a power source is necessarily required. In some embodiments, the trolley 100 can be directly pushed by workers to achieve the sliding switching of the trolley 100 between the trailer rail 720 and the guide rail to be spliced; in some embodiments, the movement of the trolley 100 can also be achieved by setting a power structure, such as a screw structure or a linear motor; in some embodiments, the movement of the trolley 100 can also be achieved by magnetic field force, for example, a magnet is installed on the trolley 100, and a motor that cooperates with the magnet is installed on the trailer rail 720 and the guide rail to be spliced. The motor cooperates with the magnet to generate a magnetic field force, thereby driving the trolley 100 to move. It can be understood that the power source of the trolley 100 is not limited here, as long as the movement of the trolley 100 can be achieved.
[0037] Specifically, if Figure 1 and Figure 2As shown, the trailer mechanism 700 further includes a trailer limiting member 730 provided on the trailer body 710. The trailer limiting member 730 can abut against the trolley 100 to limit the relative position of the trailer body 710 and the trolley 100. By providing the trailer limiting member 730 on the trailer body 710 and providing the abutment block 140 on the body 110 of the trolley 100, when the trolley 100 is placed on the trailer slide rail 720, the trailer limiting member 730 abuts against the abutment block 140 of the trolley 100, thereby limiting the relative position of the trailer body 710 and the body 110 of the trolley 100.
[0038] Specifically, if Figure 1 and Figure 2 As shown, the trailer mechanism 700 includes a limiting latch 740 provided on the trailer body 710. The limiting latch 740 can be inserted into the trolley 100 to limit the relative position of the trailer body 710 and the trolley 100. By providing the limiting latch 740 on the trailer body 710 and providing the latch hole 150 on the body 110 of the trolley 100, when the trolley 100 is placed on the trailer rail 720, the limiting latch 740 is inserted into the latch hole 150, thereby limiting the relative position of the trailer body 710 and the body 110 of the trolley 100.
[0039] Furthermore, if Figure 2 As shown, the trailer mechanism 700 further includes a guide unit 750, which is used to guide the sliding direction of the trailer body 710. By providing the guide unit 750 to guide the moving direction of the trailer body 710, the trailer body 710 can be moved to a preset position along a preset path.
[0040] Specifically, if Figure 2 As shown, the guide unit 750 includes a plurality of guide wheels spaced apart in the same direction, and the guide wheels are rotationally engaged with the side walls of the trailer body 710. By providing the guide wheels, the guide wheels and the side walls of the trailer body 710 are rotationally engaged, and contact between the guide wheels and the trailer body 710 does not hinder the movement of the trailer body 710. Moreover, by providing the plurality of guide wheels spaced apart in the same direction, the plurality of guide wheels all slide in engagement with the trailer body 710, thereby defining the movement path of the trailer body 710.
[0041] Specifically, if Figure 2As shown, there are two sets of guide units 750, one on each side of the trailer body 710 along its width direction. When the trailer body 710 moves, the multiple guide wheels of at least one set of guide units 750 can abut against the trailer body 710 and rotate relative to the trailer body 710. Guide units 750 are arranged on the ground on both sides of the trailer body 710 along its width direction, and at least the multiple guide wheels of the guide units 750 can abut against the trailer body 710. In other words, at least one set of guide units 750 can play a guiding role, thereby guiding the movement direction of the trailer body 710.
[0042] In some embodiments, only one set of guide wheels of the guide unit 750 abuts against the trailer body 710 and rotates relative to the trailer body 710 .
[0043] In some embodiments, the multiple guide wheels of the two sets of guide units 750 are both in contact with the trailer body 710 and rotate relative to the trailer body 710 .
[0044] Furthermore, if Figure 2 and Figure 3 As shown, the trailer mechanism 700 further includes a clamping unit 760, which is used to clamp the trailer body 710 after the trailer rail 720 is spliced with the guide rail to be spliced. By providing the clamping unit 760, when the trailer rail 720 is aligned with the guide rail to be spliced, the trailer body 710 is clamped to prevent the trailer body 710 from shaking or shifting.
[0045] Specifically, if Figure 2 and Figure 3 As shown, the clamping unit 760 includes a limit block 761, a mounting seat 762, a swing arm 763, and a stopper 764. The limit block 761 is connected to the trailer body 710, and the swing arm 763 and the stopper 764 are both connected to the mounting seat 762. When the trailer slide rail 720 is spliced with the guide rail to be spliced, the stopper 764 abuts one side of the limit block 761, and the swing arm 763 can swing relative to the mounting seat 762 to abut the other side of the limit block 761 to clamp the limit block 761. By connecting the limit block 761 to the trailer body 710, the stopper 764 and the swing arm 763 cooperate to clamp the limit block 761, thereby clamping the trailer body 710.
[0046] It should be noted that after the trailer slide rail 720 is spliced with the guide rail to be spliced, the mounting seat 762 is fixed to the bottom surface or the mounting platform.
[0047] Specifically, if Figure 2 and Figure 3As shown, the clamping unit 760 further includes a cylinder 765 and a clamping block 766. The clamping block 766 is connected to the swing arm 763. The output end of the cylinder 765 is connected to the swing arm 763. The cylinder 765 can drive the swing arm 763 to swing so that the clamping block 766 abuts against the other side of the limit block 761. By connecting the clamping block 766 to the swing arm 763, the swing arm 763 abuts against the limit block 761 through the clamping block 766.
[0048] The present application also provides a multi-directional conveying system, including a guide rail to be spliced and a trailer mechanism 700 of any one of the above items, wherein the trailer body 710 can drive the trailer slide 720 to move to a preset position so that the trailer slide 720 and the guide rail to be spliced can be spliced. By setting the trailer mechanism 700, when the trailer body 710 moves to the preset position, the trailer slide 720 can be spliced with the guide rail to be spliced, and the trolley 100 can slide and switch between the trailer slide 720 and the guide rail to be spliced, thereby completing the on-line or off-line process, and no additional work is required to realize the on-line and off-line of the trolley 100, thereby improving the on-line and off-line efficiency of the trolley 100.
[0049] The technical features of the above-mentioned embodiments can be combined arbitrarily.
