Abstract

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

Confined space roller parts levelness method for quick

Technical field

The present invention relates to the detection method of roller parts levelness is and in particular to a kind of confined space roller parts levelness Detection method.

Background technology

In the continuous annealing process of cold rolled strip steel production, strip steel will run in airtight heating furnace, and furnace roller surface is always Contact with the strip, in the presence of strip steel and high temperature (800 DEG C about), furnace roller surface can produce abrasion.In order to ensure strip steel fortune Do not occur sideslip to affect certainty of measurement during row, the levelness of furnace roller is needed regularly to be adjusted.During adjustment furnace roller Need first to open heating furnace cover (cool stove, ventilation), then with cage, people is hung in the level using level measurement furnace roller in heating furnace Degree, then adjusts the height at furnace roller two ends according to measurement result, completes the work of furnace roller Level-adjusting.Because the periodical repair time is subject to Restriction of production, in-furnace temperature is difficult to drop to room temperature.Testing staff, generally in measurement middle in closed environment, not only needs to carry oxygen Gas alarm, fuel gas alarm etc., and frequent operation under high altitude environment, the working time is longer.

Content of the invention

It is contemplated that overcoming the defect of prior art, provide a kind of confined space roller parts levelness quick detection side Method.The present invention can help testing staff quickly, safely and accurately to complete the detection of furnace roller levelness.

In order to achieve the above object, the present invention is achieved in that a kind of confined space roller parts levelness is quickly examined Survey method;It includes a level indicator;It comprises the following steps:

Step one, makes a frock, and described frock includes: the connecting plate of an annular, a placement level indicator Platform, it is horizontally disposed with, and one end is welded on connecting plate;Two bar shaped blisters, they are separately fixed at two table up and down of platform Face;

Step 2, removes bearing cover, and the frock that step one is made is fixedly mounted on shaft end by connecting plate;

Step 3, the platform of described frock is located at 0 ° of angle, level indicator is placed on platform, measuring roller angle beta1

Step 4, takes off level indicator, rotates roll, makes the platform of described frock overturn 180 °, level indicator is placed on platform On, measuring roller angle beta2

Step 5, sample calculating roll levelness α according to the following formula:

α=(β12)/2.

Described confined space roller parts levelness method for quick, described connecting plate external diameter is less than furnace roller bearing guard Diameter 2~5mm, diameter of bore is more than bearing guard end cap screw 2mm.

The present invention, using using the furnace roller bearing guard end face principle vertical with axis (roll surface), script is had to enter in stove The project of detection moves on to outside stove, not only saves the repair time it is ensured that the safety of testing staff, also reduces energy resource consumption, not Measure in the case of blowing out and adjust.

Brief description

Below, in conjunction with specific embodiment, the present invention is further illustrated

Fig. 1 is schematic diagram of the present invention;

Fig. 2 is the left view of described frock;

Fig. 3 is the top view of described frock.

Specific embodiment

As shown in Figure 1, Figure 2 and Figure 3, a kind of confined space roller parts levelness method for quick;It includes one Level indicator;It comprises the following steps:

Step one, makes a frock, and described frock includes: the connecting plate of an annular, a placement level indicator Platform, it is horizontally disposed with, and one end is welded on connecting plate;Two bar shaped blisters, they are separately fixed at two table up and down of platform Face;(referring to Fig. 2, Fig. 3)

Step 2, removes bearing cover, and the frock that step one is made is fixedly mounted on shaft end by connecting plate;

Step 3, the platform of described frock is located at 0 ° of angle, level indicator is placed on platform, measuring roller angle beta1

Step 4, takes off level indicator, rotates roll, makes the platform of described frock overturn 180 °, level indicator is placed on platform On, measuring roller angle beta2

Step 5, sample calculating roll levelness α according to the following formula:

α=(β12)/2.

Described confined space roller parts levelness method for quick, described connecting plate external diameter is less than furnace roller bearing guard Diameter 2~5mm, diameter of bore is more than bearing guard end cap screw 2mm.
