Liftable conveying roller way device

Abstract

The invention discloses a liftable conveying roller way device. The liftable conveying roller way device is designed mainly for solving the problem that a height difference exists when devices in a forming area and a welding area on a pipe welding production line are connected. The liftable conveying roller way device comprises a lifting frame, a guiding mechanism and a driving mechanism, wherein the lifting frame is arranged behind a bending machine in the forming area and provided with conveying roller ways, the guiding mechanism is used for controlling the lifting direction of the lifting frame, and the driving mechanism is used for driving the lifting frame to rise and fall. According to the liftable conveying roller way device, on the basis of the traditional steel pipe welding production line, a certain section of fixed conveying roller way is changed into the liftable conveying roller way device on the premise that great adjustment of a workshop, cranes in the workshop and the like is not needed so that the height difference can be adjusted freely within a certain range, and accordingly the problem that the center lines of steel pipes on certain devices in front of and behind the production line are not located on the same elevation is solved.

Description

technical field [0001] The invention relates to the field of conveying equipment for a steel pipe production line, in particular to a liftable conveying roller table device applied to a welded steel pipe conveying production line. Background technique [0002] In the JCOE longitudinal welded pipe production line, the forming process of edge milling, pre-bending, bending, etc., the welding process of pre-welding, internal welding, external welding, etc., and the finishing process of diameter expansion, full circle, straightening, etc. are generally adopted. . [0003] In this type of welded pipe production line, the height of the bending machine used for forming is very high, which directly affects the height of the workshop and the driving, while the height of the equipment in the welding area and the finishing area is relatively low. Setting will cause a relatively large waste of resources, and at the same time, it will also cause inconvenience to the lifting of equipment ...

AI Technical Summary

Problems solved by technology

[0003] In this type of welded pipe production line, the height of the bending machine used for forming is very high, which directly affects the height of the workshop and the driving, while the height of the equipment in the welding area and the finishing area is relatively low. Setting will cause a relatively large waste of resources, and at the same time, it will also cause inconvenience to the lifting of equipment in the welding area and finishing area

[0004] In order to avoid the above-mentioned problems, due to the existence of site restrictions and other problems, in some production lines, the overall forming area is sunk, but this method correspondingly causes a problem of height difference between the front and back of the equipment, that is, the forming area and welding The center line of the area is not on the same level, which makes it difficult to connect equipment
