Description

Technical Field

[0001] The utility model relates to a guide conveying device, in particular to a guide conveying device for cooling a steel pipe, belonging to the technical field of steel pipes. Background Art

[0002] When hot-rolled steel pipes are rolled at high temperatures, the rolling process, ambient temperature, cooling rate, etc. will affect the performance of the hot-rolled steel pipes. The organizational structures of materials in different regions of the same steel pipe are quite different, especially for materials with thicker walls and strong hardenability, as well as seamless hot-rolled steel pipes that are integrally formed and contain alloy elements.

[0003] The present publication number is CN215657085U, which is a spray cooling device for hot-rolled seamless steel pipe production. The device comprises a base, which is fixedly connected to one end of the hot rolling mill and is used to install a conveying mechanism. The adjusting mechanism is fixedly connected to one end of the base, and the conveying mechanism is rotatably connected to one end of the adjusting mechanism. The beneficial effects of the utility model are as follows: the bidirectional screw is driven to rotate by a driving member, and the side plates on both sides begin to slide, and the distance between the guide rollers is adjusted to a suitable distance. At this time, the telescopic tube contracts or stretches, and the steel pipe is placed on the guide roller. The movement of the steel pipe drives the guide roller to rotate continuously through the bearing and the rotating shaft, which can better carry out the conveying and can meet the spray cooling effect of steel pipes of various types and sizes.

[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: 1. After the water flows through the mounting ring, it is sprayed out through the nozzle to cool the steel pipe, thereby achieving the cooling purpose of the device. However, since the nozzle cannot rotate, it is impossible to evenly spray and cool the steel pipe; 2. Since there are multiple groups of guide rollers in groups of two, each group of guide rollers is adjusted by starting the driving member, and there are multiple driving members. If the driving member is a motor, it will not only increase the production cost of the device, but also increase the maintenance cost of the device. Utility Model Content
