Problems solved by technology

[0002] In the installation project of the main drive motor of the large-tonnage rough rolling mill for hot continuous rolling, since the workshop where the main drive motor of the rough rolling mill is located is generally designed with only one 125 / 32t crane, and the total weight of the rough rolling motor rotor and stator is about 180 tons, there is a crane. Insufficient force, the original installation method needs to re-establish the hoisting equipment, the preparation workload is large, and the hoisting equipment is complicated to set up, relatively unsafe to use, relatively low in efficiency, and high in cost, thus increasing the difficulty of on-site construction

Embodiment Construction

[0026] A method for hoisting the main drive motor of a roughing mill. The method adopts the form of hoisting first and then assembling to install the rotor 6 and the stator 4 of the main drive motor of the roughing mill. The specific steps of the present invention are as follows, as Figure 1 to Figure 6 Shown:

[0027] 1) Build the stator base 3 and the rotor base 1 at the installation position of the motor, the stator base 3 and the rotor base 1 are made of square bricks, the rotor base 1 is set on both sides of the stator base 3, respectively The pad 2 is installed on the seat 3 and the rotor base 1, the pad 2 is made of I-shaped steel, and the pad 2 is fixed on the base by bolts;

[0028] 2) Before lifting the stator 4, clean the inside of the stator 4 and the surface of the rotor 6, and wrap up the shaft diameter part where the bearing is placed to prevent the stator 4 from being scratched and damaged during the installation process, and prevent pollutants from entering t...

Abstract

The invention relates to a main driving motor hoisting method of a roughing mill. In the method, a form of firstly hoisting and then assembling is adopted, and devices such as a crane, a jack, and the like are used for mounting a rotor and a stator of a main driving motor of the roughing mill, therefore, the problem of insufficient hoisting force of the crane is solved, the engineering construction efficiency is improved, and the requirement on the technical quality of construction is met. The method has the characteristics of safety, high efficiency, convenient operation, low cost, and the like and can be widely applied to assembling motors.

Description

technical field [0001] The invention relates to a construction method, in particular to a hoisting method of a rough rolling mill main drive motor. Background technique [0002] In the installation project of the main drive motor of the large-tonnage rough rolling mill for hot continuous rolling, since the workshop where the main drive motor of the rough rolling mill is located is generally designed with only one 125 / 32t crane, and the total weight of the rough rolling motor rotor and stator is about 180 tons, there is a crane. Due to the problem of insufficient force, the original installation method needs to re-establish hoisting equipment, which requires a large amount of preparation work, and the installation of hoisting equipment is complicated, relatively unsafe to use, relatively low in efficiency, and high in cost, thus increasing the difficulty of on-site construction. Contents of the invention [0003] The invention overcomes the deficiencies in the prior art and...
