Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering technology, and in particular to a magnetic adsorption level. Background Technology

[0002] In the installation and adjustment of metallurgical equipment, especially cold rolling mill roll systems, high-precision levels are crucial tools for measuring and calibrating the equipment's levelness. However, the installation environment for such equipment often involves working at heights, as the adjustment positions for alignment roller systems (such as iron rollers) are frequently located at high elevations. Under these conditions, operators need to adjust both horizontal and vertical alignment simultaneously. When operators hold or place the level for measurement, there is a risk of the instrument accidentally falling (e.g., accidentally bumping the level, or forgetting to remove the level before rotating the roller system for vertical adjustment). The consequences of this risk are extremely serious: at best, it can damage the precision level itself, increasing equipment maintenance costs; at worst, it could cause physical damage to expensive metallurgical equipment below, potentially leading to injuries to personnel, posing significant safety and economic risks. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a magnetic adsorption level to solve the problem that the instrument is prone to accidental drop when the operator holds or places it for measurement in the prior art.

[0007] In some embodiments, the level body has a built-in main bubble tube and a secondary bubble tube, and the main bubble tube and the secondary bubble tube are perpendicular to each other.

[0008] In some embodiments, each of the magnetically conductive structures includes a magnetic conductor and an electrical soft iron disposed within an opening in the magnetic conductor.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] like Figures 1-4 As shown, this embodiment discloses a magnetic adsorption level. Specifically, the magnetic adsorption level has an overall elongated structure and includes: a level body 1 and a magnetic adsorption device 2 fixedly disposed at the bottom of the level body 1.

[0023] The aforementioned level body 1 has a built-in main bubble tube 11 and a secondary bubble tube 12. The main bubble tube 11 and the secondary bubble tube 12 are arranged perpendicularly to each other and are used to measure the levelness in two orthogonal directions respectively. The level body 1 is also equipped with an adjusting screw 13 for calibrating the main bubble tube 11, and the accuracy of the level body 1 can reach up to 0.02 mm / m.

[0024] The aforementioned magnetic adsorption device 2 is fixedly connected to the bottom of the level body 1. This magnetic adsorption device 2 includes a permanent magnet 22, two magnetic isolation bodies 25, and two symmetrically arranged magnetic conductive structures. Each of the two magnetic conductive structures has an arc-shaped opening on its opposite side. The two magnetic isolation bodies 25 are respectively embedded in the mating points of the two magnetic conductive structures to separate them. The function of the magnetic isolation bodies 25 is to effectively magnetically isolate the two magnetic conductive structures. The two magnetic isolation bodies 25 and the two magnetic conductive structures together form a circular cavity. The permanent magnet is rotatably disposed in the circular cavity, and a magnetic switch 21 is fixedly connected to the permanent magnet (e.g., via a connecting rod or directly fixed to the surface of the permanent magnet). Specifically, by rotating the magnetic switch 21, the permanent magnet 22 can be rotated within the circular cavity, thereby changing the position of its magnetic pole direction (SN pole) relative to the magnetic conductive structures. Figure 3 As shown, when the magnetic switch 21 is rotated so that the SN poles of the permanent magnet 22 are perpendicular to the line connecting the two magnetic shielding bodies 25 (at this time, neither the SN poles of the permanent magnet 22 are in contact with the magnetic shielding body 25), the magnetic conductive structure has strong magnetism and can thus firmly adhere to the iron equipment below; as Figure 4 As shown, when the rotating magnetic switch 21 causes the SN poles of the permanent magnet 22 to align with the two magnetic shields 25 respectively (at this time, the SN poles of the permanent magnet 22 are in contact with the upper and lower magnetic shields 25), the magnetic guiding structure demagnetizes and separates from the iron equipment below.

[0025] Each of the above magnetic conductive structures includes a magnetic conductor 24 made of cast iron with an arc-shaped opening, and a C-shaped electrical soft iron 23 disposed inside the arc-shaped opening of the magnetic conductor 24.

[0026] In an embodiment of this invention, the two magnetic adsorption devices 2 further include a magnetic shielding layer 26. This magnetic shielding layer 26 is disposed between the two magnetically conductive structures and the level body 1. Its function is to prevent the strong magnetic field generated by the magnetic adsorption devices from interfering with the accuracy of the bubble tube inside the level body 1. The aforementioned magnetic shielding body 25 and magnetic shielding layer 26 can be made of brass or aluminum. Specifically, the magnetic shielding layer and the upper magnetic shielding body 25 can be an integral structure, meaning they are made from the same piece of brass or aluminum material, forming an integrated magnetic isolation barrier.
