Description

Painting tool for monitoring nut loosening mark

Technical Field

The utility model relates to the technical field of machinery, especially, relate to a control nut not hard up instrument of painting of sign.

Background

The large and medium bridges in China exceed 8 thousands of seats and are ascending at the top of the world at present, wherein steel structure bridges are widely adopted due to high construction speed, high safety level and convenience in maintenance, steel structures are difficult to guarantee due to welding of local stress and easy corrosion, and are gradually replaced by high-strength bolts at present, but high-strength bolts and nuts are easy to loosen. For example, the steel structure part of the steel-concrete composite beam structure of the Qihe Huanghe bridge consists of side box beams, cross beams and small longitudinal beams which are all connected by high-strength bolts, nuts are loosened and fall off after the bridge is opened for a short time, the number of the high-strength bolts reaches 38700, the noon temperature in the steel box beam reaches more than 46 ℃ in summer, the internal temperature of the steel box beam is also more than 38 ℃ when the outdoor temperature is 30 ℃ at night, the manual inspection is tedious, time-consuming and labor-consuming, more than 6 hours are needed when an individual 840 m steel box beam 2 enters the box beam for inspection, ventilation and no light line exist in the steel box beam, and danger is caused by sunstroke very easily. Because the electrostatic shielding in the steel box girder does not have any signal, once danger occurs, the steel box girder cannot be contacted with the outside, and the transverse partition plate manhole is arranged in the steel box girder, so that the rescue is very difficult. The loosening of the nut is the starting point of water leakage and rust disease, and brings great hidden trouble to driving safety, so the high-strength bolt must be frequently checked.
