Abstract

The invention discloses a boiler pipe drawing device and a pipe drawing technology by the device, and solves the problems that a traditional boiler pipe drawing technology is complex in process, difficult in drawing and large in workload, damage to boiler pipe plates and boiler pipes in the drawing process is large and the like. The device comprises a guide rail and a mold, the guide rail comprises a supporting pipe and a baffle plate, and the mold comprises a supporting plate, a supporting rod, a connecting lead screw, a connecting plate, a connecting short pipe, a sleeve and an adjusting nut. When a pipe is drawn, the guide rail is inserted into the boiler pipe, the mold is mounted on a boiler pipe plate, the pipe can be drawn by rotating the adjusting nut, the whole pipe drawing process is simple and convenient, damage to the boiler pipe plate and the boiler pipe is small, and the device has a great popularization value in terms of boiler disassembly.

Description

technical field [0001] The invention relates to the technical field of boiler maintenance, in particular to a boiler tube pulling device and a tube pulling process through the device. Background technique [0002] Taking a DZL4-1.25-WⅡ type coal-fired steam boiler as an example, the boiler drum part is mainly composed of a boiler tube plate, a cylinder body and a boiler tube. Since the assembly process of the boiler tube and the boiler tube plate is to first assemble the two ends of the boiler tube After expanding the tube, it is welded with the boiler tube plate. The exposed boiler tube plate at both ends of the boiler tube is only about 6mm. When the boiler tube needs to be pulled out for maintenance or faulty replacement, it is difficult to pull out because the focus range is too small. The traditional process of pulling out the boiler tube is to remove the weld between the boiler tube and the boiler tube plate through external force, so that the tube hole of the boiler t...
