A magnetic line drop anti-corrosion device

Abstract

The invention relates to the technical field of building detection, and discloses a magnetic force line pendant anticorrosion device. A rotating shaft is movably installed on the middle and upper ends of the box body, and a wire rope is fixedly connected to the outer surface of the rotating shaft, and an expansion piece is slidably connected to the outer surface of the wire rope. The expansion piece A fixed block is fixedly installed at one end away from the wire rope, and a clamping block is fixedly installed on the lower surface of the fixed block. The outer surface of the wire rope is slidably connected with a water removal sheet, and the lower surface of the water removal sheet is fixedly installed with a liquid storage tank. Through the combined use of water removal sheet, liquid storage tank, compression spring, card cone and dust removal block, the lime and dust attached to the surface of the wire rope can be effectively removed first, and then detailed lime removal can be carried out through the liquid storage tank. The advantage of the lime powder contaminated by the wire rope itself during the measurement process ensures that the magnetic force line pendant will not be easily corroded and broken during use, which protects the personal safety of the staff and reduces the safety of the staff during use. Security risks.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a magnetic force line drop anticorrosion device. Background technique [0002] The magnetic force line pendant is suitable for verticality detection in other fields such as building inspection and installation engineering, and is also suitable for verticality detection of steel pipe columns or steel column installation projects with a height of 3 to 5m. Now take the vertical pipeline installation project as an example to describe The verticality detection method is to first pull the line pendant out of the magnetic box for a certain length, then attach the magnetic box to a height that the operator can reach, and then use a steel tape measure to measure the height of 1m. When the line pendant is stable Finally, use a steel ruler to measure the verticality deviation value at the upper end of the wire drop.

AI Technical Summary

Problems solved by technology

[0003] In construction sites, magnetic force line pendants are still used more often. However, in order to save costs and effectively mark at the same time, current construction sites often use white lime powder to coat the ground or walls. As we all know, Lime powder is calcium carbonate, which is an alkaline corrosive substance. When the magnetic force line pendant is used to measure the object, it is likely to be contaminated with some lime powder. The moisture in the air reacts. As time goes by, the wire rope may be slowly corroded, eventually causing the wire rope to break. If the wire rope breaks during the measurement process, the wire drop itself is heavy, and the acceleration of gravity If it falls on a person, it is likely to injure the staff, and there is a great potential safety hazard
