Problems solved by technology

[0002] Rotary kiln is a relatively common cement building material equipment. It has important application value in metallurgy, cement, chemical industry and other fields. Due to the large diameter and heavy weight of the rotary kiln body, although it can be assembled by using a crawler crane, the two-section cylinder The distance between kiln bodies is difficult to control precisely, and due to the weight of the kiln body and collisions during transportation, the roundness of the kiln body is deviated

Abstract

The invention discloses a rotary kiln body pair-combining splicing-assembly alignment device and a construction method and belongs to the technical field of rotary kiln installation. The rotary kiln body pair-combining splicing-assembly alignment device comprises a barrel body, the barrel body is composed of seven barrel sections, the inner surface of each barrel section is provided with a lengthways adjusting device and a radial adjusting device correspondingly, each lengthways adjusting device is composed of a fixed support seat, an inner side nut, a fixed screw rod and an outer side nut, and each radial adjusting device is composed of an L-shaped fixed block, a radial adjusting nut and a radial adjusting bolt. By means of the rotary kiln body pair-combining splicing-assembly alignment device and the construction method, the barrel body is divided into parts and performed ground splicing-assembly, lifting in the air is performed after the barrel body is formed into segments by splicing-assembly, the work efficiency is effectively improved, the construction cost is lowered, when the welding line separation distance of the adjacent barrel sections is larger or smaller, adjustment can both be performed through the lengthways adjusting devices, sunken positions can further be jacked up utilizing the radial adjusting bolts, and the fact that the barrel body has integrity and no appearance defects after construction is finished is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rotary kiln installation, and more specifically, relates to a rotary kiln kiln body assembly alignment device and construction method. Background technique [0002] Rotary kiln is a relatively common cement building material equipment. It has important application value in metallurgy, cement, chemical industry and other fields. Due to the large diameter and heavy weight of the rotary kiln body, although it can be assembled by using a crawler crane, the two-section cylinder The distance between kiln bodies is difficult to control accurately, and due to the weight of the kiln body and collisions during transportation, the roundness of the kiln body is deviated. However, since the rotary kiln is the core equipment of the project, the overall straightness and assembly welding requirements of the rotary kiln are extremely high. Therefore, it is necessary to accurately adjust the distance of the entire contact ...
