Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot galvanizing, in particular to an assembling device and method for efficiently assembling a galvanizing line roller set. BACKGROUND

[0002] Hot galvanizing, also known as hot dip zinc and hot dip galvanizing, is an effective metal corrosion protection method, mainly used for metal structure facilities in various industries. Hot galvanizing immerses a steel piece after rust removal into a molten zinc liquid at about 500°C, so that a zinc layer is attached to the surface of the steel member, thereby achieving the purpose of corrosion protection.

[0003] The hot galvanizing roller set in the zinc-aluminum pot of the galvanizing line is an important production equipment of the galvanizing line. The hot galvanizing roller set is composed of three parts: a submerged roller, a front stabilizing roller, and a rear stabilizing roller. The assembled roller set is hoisted into the zinc pot for work after preheating.

[0004] The existing assembly method is generally as follows: the roller set is assembled in the assembly room using the existing assembly frame; after assembly, the roller body is preheated using the existing preheater, and then the roller set is transported to the installation site using a roller set transport vehicle. The existing assembly method has the following disadvantages:

[0005] ①Roller body assembly leveling requires adding pads under the roller seat and measuring with a level after adding pads. Since the pads need to be added and removed multiple times using a crane for leveling, it is time-consuming and the precision is not high, and the deviation is usually about ±0.9mm;

[0006] ②When assembling and pre-adjusting the center line, a press is used to weld a block around the roller seat, which is time-consuming and has low precision, and the deviation is usually about ±0.9mm;
