Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to a plate chain conveying equipment. Background Art

[0002] When a finished rolling mill is in use, in order to improve production efficiency and material handling capacity, automated conveying equipment is often used. Conventionally, roller table drive is used. The advantage of roller table conveying is low price. There is also plate chain conveying equipment, whose advantages are stable conveying, small impact force, and moderate price. When conveying rolled steel, the latter is usually more cost-effective. Existing chain plate conveying equipment generally realizes the horizontal transportation of goods through multiple uniformly distributed chain plates, thus facilitating the transportation and docking of goods.

[0003] For example, Chinese Patent with application number CN202122159574.1 discloses a chain plate pneumatic lifting and transferring conveying equipment, including a chassis, a lifting assembly, and a conveying assembly; the lifting assembly includes a cylinder and a lifting plate; the conveying assembly includes a support frame, chain plates, and a transmission assembly. By arranging four cylinders at the bottom of the support frame, the conveying assembly is driven to lift by the cylinders, and the conveying assembly realizes the horizontal transportation of goods through multiple uniformly distributed chain plates, thus facilitating the transportation and docking of goods. However, the finished steel products after bundling are tied with steel bars, and the joint positions are prone to height differences. When the bundled parts pass through the gaps between each chain plate, there is an impact each time. In addition, the existing technology with multiple uniformly distributed chain plates does not have a flipping function. The joints frequently impact the overall chain plate, which will cause uneven wear of the chain, and may cause the conveying chain to deviate from the predetermined track, affecting the service life of the equipment.
