A micro damage detection dust isolation device

Abstract

The invention discloses a micro-damage detection and dust isolation device, which relates to the field of concrete detection. The device includes a dust collection cover, one side of the dust collection cover is provided with an opening, and the other side is provided with a sliding hole, a sliding pipe is slidably connected in the sliding hole, and a pressing part is provided on the inner wall of the sliding pipe, and the pressing part is used for pressing Tighten the outer wall of the chuck of the electric hammer; the end of the sliding tube located inside the dust collection hood is provided with an inner retaining ring for resisting the inner wall of the dust collection hood, and the end located outside the dust collection hood is provided with an outer stop for resisting the outer wall of the dust collection hood lock up. The present invention has the following advantages and effects: by setting a dust collection cover that can be installed on the electric hammer, the dust falling on the wall is automatically collected, so that the effect of automatic dust collection is achieved, and at the same time, dust is prevented from polluting the ground or affecting construction operators of good health.

Description

technical field [0001] The invention relates to the field of concrete detection, in particular to a micro damage detection dust isolation device. Background technique [0002] Reinforced concrete is widely used in construction projects at this stage. However, the actual service life of some reinforced concrete structures is far less than the design period due to diseases. Among them, the diseases caused by deviations in the thickness of the protective layer are the most common. Therefore, it is necessary to detect the thickness of the concrete protective layer. [0003] The traditional method of detecting the thickness of the concrete cover can be combined with the general measurement (non-damage) and local excavation (micro-damage) of the steel detector. However, when excavating, an electric hammer is often used to slightly damage the wall. At this time, a large amount of dust will fall on the wall, which not only threatens the health of construction operators, but also po...

Problems solved by technology

However, when excavating, an electric hammer is often used to slightly damage the wall. At this time, a large amount of dust will fall on the wall, which not only poses a threat to the health of construction operators, but also pollutes the ground, which needs to be improved.
