Problems solved by technology
Due to the limited production time for scheduled repairs, it is difficult to lower the temperature in the furnace to normal temperature
Inspection personnel usually measure in a closed environment, not only need to carry oxygen alarms, gas alarms, etc., but also often work in high-altitude environments, and the working hours are longer

Embodiment Construction
[0017] Such as figure 1 , figure 2 and image 3 Shown, a kind of closed space roller type parts levelness rapid detection method; It comprises a spirit level; It comprises the following steps:
[0018] Step 1, making a tooling, the tooling includes: a circular connecting plate, a platform for placing a spirit level, which is set horizontally, and one end is welded on the connecting plate; two strip-shaped blisters are respectively fixed on the upper and lower sides of the platform Two surfaces; (see figure 2 , image 3 )
[0019] Step 2, remove the end cover of the bearing seat, and fix the tooling made in step 1 to the end of the shaft through the connecting plate;
[0020] Step 3, set the platform of the tooling at an angle of 0°, put the level on the platform, and measure the angle β of the roller 1 ;
[0021] Step 4, take off the spirit level, turn the roller, turn the platform of the tooling 180°, put the spirit level on the platform, and measure the angle β of t...

The invention relates to a method for quickly detecting the levelness of roller parts in an airtight space. A gradienter is used in the method. The method comprises the following steps: 1) manufacturing a working assembly; 2) dismounting an end cover of a bearing base and fixedly mounting the working assembly on a shaft end part through a connecting plate; 3) setting a platform of the working assembly at a zero angle, placing the gradienter on the platform and measuring a roller angle beta1; 4) taking down the gradienter, rotating the roller, turning the platform of the working assembly for 180 degrees, placing the gradienter on the platform and measuring a roller angle beta 2; and 5) calculating a roller levelness alpha according to the formula: alpha=(beta1+beta 2) / 2, wherein the working assembly comprises the circular connecting plate, the platform used for placing the gradienter and two bar-shaped bubbles; the platform is horizontally placed; one end of the platform is welded with the connecting plate; and the two bar-shaped bubbles are respectively and fixedly arranged on upper and lower two surfaces of the platform. According to the method provided by the invention, an inspector can quickly, safely and accurately finish the detection for the levelness of a furnace roller.
Description
technical field [0001] The invention relates to a method for detecting the levelness of roller parts, in particular to a method for detecting the levelness of roller parts in a closed space. Background technique [0002] In the continuous annealing process of cold-rolled strip production, the strip runs in a closed heating furnace, and the surface of the furnace roll is always in contact with the strip. Under the action of the strip and high temperature (about 800°C), the surface of the furnace roll will wear and tear. In order to ensure that the measurement accuracy is not affected by deviation during strip running, the levelness of the furnace rolls needs to be adjusted regularly. When adjusting the furnace roll, it is necessary to open the heating furnace cover (cooling furnace, ventilation), and then use a hanging cage to hoist people into the heating furnace and use a level to measure the level of the furnace roll, and then adjust the height of the two ends of the furn...
