Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] A large-scale flotation machine rotor offline assembly method, the assembly method steps are:

[0017] ⑴. Make a special support device: including four columns, two bottom beams 5, and four main diagonal braces. The four columns are arranged at the four corners of the rectangle. The main diagonal braces 9 and 10 are set between the two uprights, and each upright is composed of a bottom upright 1 and an extended upright 2, the bottom upright and the upright are fixed by connecting bolts 8, and the bottom upright and the bottom beam are installed There are bottom reinforced diagonal braces 6, lengthened diagonal braces 7 are installed between the extended column and the bottom beam, a rotor support surface 3 is arranged on the upper end...

Abstract

The invention relates to an off-line assembling method of a large flotation machine rotor. The assembling method includes the steps that (1) a special supporting device is manufactured; (2) the large flotation machine rotor is assembled; (3) a flotation machine barrel is installed on an equipment installing site in a factory building; (4) the assembled rotor and the support are stored and transported integrally, after arriving at the equipment installing site in the factory building, linkage bolts of the rotor and the support are loosened, and the rotor is hoisted to the flotation machine barrel through a lug to finish assembly of the large flotation machine rotor. The rotor assembled in an off-line mode in advance is installed in an on-line mode on the equipment installing site in the factory building. Because off-line assembly and on-line installation are not on the same working face, the occupied area of operation face of the installation site is small, so that construction equipment, manpower and other resources are used sufficiently, construction efficiency of on-line installation of the rotor is improved, the overall installation construction period of flotation equipment is shortened, meanwhile, intersection, high-altitude and limited space operation is reduced, and safety risks of construction are reduced.

Description

technical field [0001] The invention belongs to the field of flotation equipment installation, in particular to an off-line assembly method for a rotor of a large flotation machine. Background technique [0002] The flotation machine is one of the main equipment of the mineral processing plant. Due to the large number of flotation machines in the large mineral processing plant and the same structure, it has the characteristics of many spare parts, heavy on-site installation workload and long installation period. How to improve the installation efficiency of the flotation machine and ensure the project quality and construction progress is the key link and key process for the installation of the flotation machine in the mineral processing plant, especially the installation of the rotor of the large flotation machine. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an off-line assembly method...
