Description

Technical Field

[0001] This utility model relates to the field of suspended conveying equipment technology, and in particular to a variable-distance suspended conveying device. Background Technology

[0002] The overhead conveyor system is a highly automated, integrated aerial storage and transportation system that saves ground space. Its wiring design can be tailored to different process requirements, allowing it to operate not only in ordinary environments but also traverse drying ovens, paint booths, and production areas with hazardous gases. It is an indispensable logistics device for modern enterprises. In sheet metal coating workshops, the overhead conveyor system can use multiple sections of suspended accumulation chains to hoist and transport multiple sheets of material, then convey them to the spraying equipment for coating, achieving efficient, assembly-line spraying.

[0003] Traditional overhead conveyor systems use a fixed pitch for the multi-section overhead accumulator chain, resulting in a fixed spacing between the sheets. This allows for the conveying of sheets of fixed widths in a fixed pattern. However, when the width of the sheets changes, the spacing between them cannot be effectively adjusted. If the sheets are too narrow, gaps will appear between adjacent sheets, causing them to wobble and collide during transport, resulting in poor conveying stability and affecting normal transport and subsequent coating processes. Conversely, if the sheets are too wide, adjacent sheets may be squeezed together, again affecting normal transport and subsequent coating processes, thus reducing workshop production efficiency. Utility Model Content

[0004] To address the technical problem in existing technologies where the spacing between plates during transport cannot be effectively adjusted according to the width of the plates, resulting in poor stability of the plates during transport and affecting the transport and coating processes, this utility model provides the following technical solution.

[0005] This utility model discloses a variable-pitch suspended conveyor device, comprising a hoisting track and a plurality of accumulation chains connected to the hoisting track. A plurality of lifting rods are connected to the lower part of each accumulation chain. A plurality of first slip rings and a plurality of second slip rings are slidably connected to the outer periphery of each lifting rod. The lower parts of the first and second slip rings are respectively connected to a first fixing block and a second fixing block with identical structures and arranged opposite to each other. An adjusting member connects the first and second fixing blocks. The lower parts of the first and second fixing blocks are respectively connected to lifting chains with identical structures and arranged opposite to each other for suspending plates. The adjusting member drives the lifting chains to move closer or further apart.

[0006] As a further technical solution, the adjusting component includes a first threaded rod fixedly connected to the first fixed block and a second threaded rod fixedly connected to the second fixed block, with the first threaded rod and the second threaded rod having opposite thread directions, and an adjusting sleeve connected to one end of the first threaded rod and the second threaded rod that are close to each other.

[0007] As a further technical solution, the upper part of the boom is provided with several adjustment holes, and the first slip ring is threadedly connected with a locking bolt that matches the adjustment holes.

[0008] As a further technical solution, the first fixing block and the first slip ring, as well as the second fixing block and the second slip ring, are detachably connected.

[0009] As a further technical solution, each of the booms is arranged close together so that the first slip ring and the second slip ring can be freely adjusted between two adjacent booms.

[0010] As a further technical solution, the first slip ring and the second slip ring are arranged in pairs.

[0011] The beneficial effects of this utility model are as follows: The lower part of the accumulating chain is connected to multiple lifting rods, and multiple first and second slip rings are slidably connected to the lifting rods. The first and second slip rings are arranged in groups and correspondingly suspend a sheet material. When the first and second slip rings slide freely on the outer circumference of the lifting rods, the distance between adjacent sheet materials can be adjusted. When conveying wider sheet materials, the distance between adjacent sheet materials can be increased by sliding the first and second slip rings on the lifting rods; when conveying narrower sheet materials, the distance between adjacent sheet materials can be decreased by sliding the first and second slip rings on the lifting rods. Thus, the spacing of the sheet materials can be adaptively adjusted according to the actual width of the sheet material. Therefore, the spacing of the sheet materials during conveying by the suspended conveyor device can be effectively adjusted according to the width of the sheet materials, improving the stability of the sheet materials during the conveying process, ensuring normal conveying of the sheet materials and the subsequent coating process, and ensuring the production efficiency of the workshop.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0017] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a variable-pitch suspended conveyor device, comprising a hoisting track 1 and several accumulation chains 2 connected to the hoisting track 1. Several lifting rods 3 are connected to the lower part of the accumulation chains 2, and the lifting rods 3 are used for hoisting and transporting sheet metal. In existing suspended conveyor devices, each lifting rod 3 only hoists one sheet metal. In this utility model, each lifting rod 3 can hoist more than one sheet metal; multiple lifting rods 3 cooperate with each other to adjust the spacing between adjacent sheet metal, ensuring the stability of the hoisted sheet metal while allowing for the hoisting of more sheet metal. The hoisting track 1 and accumulation chains 2 adopt existing structures, therefore their specific structures and operating methods will not be described in detail.

[0019] In a preferred embodiment, a plurality of first slip rings 4 and a plurality of second slip rings 5 ​​are slidably connected to the outer periphery of the boom 3. The first slip rings 4 and the second slip rings 5 ​​are arranged in pairs, and the first slip rings 4 and the second slip rings 5 ​​can slide freely on the outer periphery of the boom 3. The distance between the first slip rings 4 and the second slip rings 5 ​​in each group is adjustable, and the distance between adjacent second slip rings 5 ​​and first slip rings 4 in two adjacent groups is also adjustable. Thus, the spacing between two adjacent boards can be adjusted according to the width of the actual board product, thereby improving the stability of the board during the conveying process.

[0020] In a preferred embodiment, the lower parts of each set of first slip rings 4 and second slip rings 5 ​​are respectively connected to a first fixing block 7 and a second fixing block 8 with identical structures and arranged opposite to each other. An adjusting member 6 is connected between the first fixing block 7 and the second fixing block 8. The adjusting member 6 can adjust the distance between the first fixing block 7 and the second fixing block 8, thereby adjusting the distance between the first slip ring 4 and the second slip ring 5. When the first slip ring 4 moves, the second slip ring 5 can move accordingly, ensuring the stability of the set of first slip rings 4 and second slip rings 5 ​​during the movement process. The lower parts of the first fixing block 7 and the second fixing block 8 are respectively connected to a lifting chain 10 with identical structures and arranged opposite to each other for suspending the board. The two lifting chains 10 are used to suspend one board. The adjusting member 6 adjusts the distance between the first fixing block 7 and the second fixing block 8. Therefore, the adjusting member 6 can drive the two lifting chains 10 to move closer or farther apart, so as to adapt to boards of different widths.

[0021] In a preferred embodiment, the adjusting member 6 includes a first threaded rod 602 and a second threaded rod 603 with opposite thread directions. The first threaded rod 602 is fixedly connected to the first fixed block 7, and the second threaded rod 603 is fixedly connected to the second fixed block 8. An adjusting sleeve 601 is connected to one end of the first threaded rod 602 and the second threaded rod 603. The two sides of the adjusting sleeve 601 are respectively matched with the first threaded rod 602 and the second threaded rod 603. Tightening the adjusting sleeve 601 can make the first threaded rod 602 and the second threaded rod 603 move closer or further apart, which can pull the first fixed block 7 and the second fixed block 8 closer or further apart. As a result, the distance between the first slip ring 4 and the second slip ring 5 is adjusted, and the distance between the two lifting chains 10 is also adjusted, which can accommodate plates of different widths.

[0022] In a preferred embodiment, the upper part of the boom 3 is provided with a plurality of adjustment holes 301, which are evenly distributed along the length of the boom 3. The first slip ring 4 is threadedly connected with a locking bolt 9 that matches the adjustment hole 301. Of course, both the first slip ring 4 and the second slip ring 5 can also be connected with locking bolts 9; this invention does not impose any particular limitation on this. After the distance between the first slip ring 4 and the second slip ring 5 in each group has been adjusted, the first slip ring 4 of one group is pulled to adjust the distance between it and the second slip ring 5 of the adjacent group. After adjustment, the locking bolt 9 is used to lock the first slip ring 4 to the boom 3. This allows the spacing between two adjacent plates to be adjusted according to the width of the plate, improving the stability of the plates during the conveying process.

[0023] In a preferred embodiment, the first fixing block 7 and the first slip ring 4, as well as the second fixing block 8 and the second slip ring 5, are detachably connected, for example, by existing threaded connections or pin connections. When the first slip ring 4 or the second slip ring 5 on the hanger 3 is inconvenient to move, the first fixing block 7 or the second fixing block 8 can be disassembled and connected to an adjacent first slip ring 4 or second slip ring 5. Simultaneously, each adjacent hanger 3 is arranged close together to allow the first slip ring 4 and the second slip ring 5 to be freely adjusted between adjacent hanger 3s, adapting to a wider range of sheet metal widths, and enabling more effective adjustment of the spacing between the sheet metals.

[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
