Background

If the building is not treated in time after cracks appear, a series of problems such as water leakage and inclination can appear, the building collapses, economic loss is caused, and the life safety is threatened, so the building needs to be repaired in time after the cracks appear, the cracks are generally required to be pretreated for more firm repair when the cracks are repaired, concrete structures are chiseled off, the contact surface and the adhesive force between the building structure and the repaired are increased, and the air pick is generally adopted for treatment at present.

The air pick is a hand-held construction machine tool which takes compressed air as power and utilizes the impact action to break hard objects, is a breaking device commonly used in construction engineering, and when the air pick is used, the compressed air is taken as the power, and the compressed air is alternately distributed at the two ends of a cylinder body through an air distribution assembly so as to lead a hammer body to reciprocate to impact a drill bit, thereby breaking the struck objects. The size of the impact force of the air pick is determined by the weight and the speed of the hammer body, but the traditional air pick is influenced by the prejudice that the impact force is larger as the self weight is heavier, some air pick products generally adopt the increased weight to improve the impact force, so that operators pay much useless work in the carrying and using processes, while the light air pick has insufficient impact due to the smaller hammer body, although the moving speed of the hammer body can be adjusted by controlling compressed air, the control is difficult and the effect is poor, so that a crack pretreatment device for waterproof construction of a building structure is required to be designed to solve the problems.
