DETAILED DESCRIPTION
[0023] The utility model provides a structure in which the cross beam is not easily deformed. Figure 1 , 6As shown, the telescopic loading conveyor line includes a fixed layer 1, a second movable layer 2, and a third movable layer 3 distributed up and down. The second movable layer 2 is movably connected to the fixed layer 1, and the third movable layer 3 is movably connected to the second movable layer 2. A ring-shaped conveyor line 4 is installed at the lower end of the third movable layer 3, and a carrier (not shown in the figure) is hung on the conveyor line 4. The carrier can be driven to move around the ring-shaped conveyor line 4. The specific structure of the conveyor line 4 can be referred to CN2017205995180. The fixed layer 1 is fixedly installed on the frame or under the roof through a suspension rod 5.
[0024] like Figure 1 , 2 As shown in Figure 3, the movable connection structure of the upper layer and the lower layer specifically includes an upper I-shaped member 6 and a lower I-shaped member 6. The I-shaped member 6 extends in the length direction, and the I-shaped member can be made of I-shaped steel. The lower flange plate 6.1 of the upper I-shaped member 6 is fixedly installed with a connecting plate, and a roller 8 is installed on the connecting plate. The roller 8 is located below the upper flange plate of the lower I-shaped member 6. The top of the roller 8 abuts against the upper flange plate, so that the upper I-shaped member and the roller cooperate to hang the lower I-shaped member, and at the same time, good telescopic performance can be achieved. The connecting plate shown in the figure is a "concave" plate 7 with an opening downward, and a roller 8 is installed on both sides of the "concave" plate 7. A roller 8 can be installed on the front or / and rear side of each roller 8 (along the length direction of the I-shaped member). There is a gap between the highest point of the roller 8 and the "concave" plate 7 to accommodate the upper flange plate 6.2 of the I-shaped member 6 of the lower layer. The top of the roller 8 abuts against the upper flange plate 6.2 of the lower I-shaped member 6, and the support wheel 9 abuts against the web plate 6.3 of the lower I-shaped member 6. In this embodiment, two support wheels are arranged on both sides of the concave plate 7, that is, a total of four support wheels, and one support wheel can also be arranged on each side, or even no support wheel is arranged.
[0025] Combine the following Figure 1 , 23. The specific arrangement of the three layers of I-shaped components in this embodiment is described in detail. The two sides of the fixed layer 1 are connected to the I-shaped components through the cross beam 10 along the length direction of the I-shaped components, and the upper edge wing plate of the I-shaped components of this layer is connected to the suspension rod 5. The two sides of the second movable layer 2 and the third movable layer 3 are connected to the I-shaped components of this layer through the cross beam along the length direction of the I-shaped components. The I-shaped components on both sides of the fixed layer 1, the second movable layer 1, and the third movable layer 3 are connected through the longitudinal beam 16, and the two ends of the longitudinal beam 16 are specifically connected to the cross beam 10. A concave plate 7 with an opening downward is arranged between the lower edge wing plate of the I-shaped component of the fixed layer 1 and the upper edge wing plate of the I-shaped component of the second movable layer 2. The concave plate 7 is installed on the lower edge wing plate of the I-shaped component of the fixed layer 1, and the roller 8 on the concave plate 7 abuts against the lower surface of the upper edge wing plate of the I-shaped component of the second movable layer 2, and the roller abuts against the web of the I-shaped component. Through this structure, the second movable layer is suspended on the fixed layer 1 via the roller 8 and the concave plate 7. When the second movable layer 2 is extended and retracted relative to the fixed layer 1 by external force, the I-shaped member of the second movable layer 2 is in roller contact with the roller 8, so that both movable connection and relative movement are achieved, and the friction of rolling contact is small. A concave plate 7 with a downward opening is arranged between the lower edge wing plate of the I-shaped member of the second movable layer 2 and the upper edge wing plate of the I-shaped member of the third movable layer 3. The concave plate 7 is installed on the lower edge wing plate of the I-shaped member of the second movable layer 2. The roller 8 on the concave plate 7 abuts against the lower surface of the upper edge wing plate of the I-shaped member of the third movable layer 3, and the roller abuts against the web of the I-shaped member. Through this structure, the third movable layer is suspended on the second movable layer 2 via the roller 8 and the concave plate 7. When the external force drives the third movable layer 3 to expand and contract relative to the second movable layer 2, the I-shaped component of the third movable layer 3 is in roller contact with the roller 8, thereby realizing both movable connection and relative movement, and the friction of rolling contact is small.
[0026] like Figure 3 As shown, the cross beam 10 is located below the roller 8 and is installed on both sides of the web 6.3. On the one hand, the cross beam 10 is used to achieve connection with the longitudinal beam 16 of the layer, and on the other hand, it plays a role in limiting the upper roller 8.
[0027] like Figure 1 As shown, the fixed layer 1 is provided with a first position detection device 11-1 and a second position detection device 11-2, which are respectively used to detect the extreme extension position and the retracted position of the second movable layer 2. When the second movable layer and the third movable layer are telescopically movable, when the first position detection device 11-1 detects the first sensing device on the second movable layer, the second movable layer is extended to the extreme extension position, and correspondingly the third movable layer is also extended to the extreme extension position. When the second position detection device 11-2 detects the second sensing device on the second movable layer, the second movable layer is retracted to the retracted position, and correspondingly the third movable layer is also retracted to the retracted position.
[0028] like Figure 4 , 5 As shown, the rear ends of the second movable layer 2 and the third movable layer 3 are provided with an anti-warping device, which is arranged at an end away from the extended end. It includes a second "concave" plate 12 installed at the end of the I-shaped member 6 of the lower layer, the second concave plate opens upward, and a second roller 13 is installed on both sides of the second "concave" plate 12, and the high point of the second roller 13 is against the lower surface of the lower edge wing plate 6.1 of the I-shaped member 6 of the upper layer. Specifically, a second concave plate with an upward opening is installed at the end of the I-shaped member of the third movable layer 3, and the second roller of the second concave plate is against the lower surface of the lower edge wing plate of the I-shaped member of the second movable layer 2. When the third movable layer 3 is extended, its rear end is against the I-shaped member of the second movable layer through the roller on the corresponding second concave plate to prevent the tail end from warping. The end of the I-shaped member of the second movable layer 2 is installed with a second concave plate with an opening facing upward. The second roller of the second concave plate abuts against the lower surface of the lower edge wing plate of the I-shaped member of the fixed layer 1. When the second movable layer 2 is extended, its rear end abuts against the I-shaped member of the fixed layer through the roller on the corresponding second concave plate to prevent the tail end from tilting up. After the second movable layer 2 and the third movable layer 3 are extended, the anti-warping device prevents the end away from the extended end from tilting upward due to the gravity of the extended end and the clothing hung on the conveyor line 4, thereby preventing the extended end from bending downward. It should be noted that the second connecting plate is not limited to a structure such as a second concave plate with an opening facing upward, as long as the second roller can be installed and the second roller is allowed to abut against the lower edge wing plate.
[0029] In order to further prevent the conveyor line 4 from bending downward, a supporting device for supporting the conveyor line 4 is also provided, including a supporting bracket 14 installed below the conveyor line 4, and a floor roller 15 is installed at the lower end of the supporting bracket 14. Thus, the conveyor line 4 is supported from the ground.
[0030] The telescopic driving mechanism of the active layer in this embodiment can adopt the structure disclosed in CN2019218045768, which will not be repeated here. The mechanism that can be used for driving the active layer in the prior art can also be applied in this embodiment.
