Hammering device for high strain detection
The invention provides a high-strain detection hammering device, which belongs to the field of hammering detection and comprises a fixing plate, a plurality of supporting piles, a side edge tensile structure, a buffer spring, a hollow cylinder with a bottom, gunpowder and a hammering plate, the fixing plate is in a flat plate shape. The side edge tensile structure comprises a plurality of tensile steel bars which are symmetrically distributed on the side edges of the periphery of the fixing plate. The upper portions of the tensile steel bars are fixed to the fixing plate, and the lower portions of the tensile steel bars are connected with the supporting piles. The buffer spring is fixedly connected below the center position of the fixed plate; the lower part of the buffer spring is connected with the inverted hollow cylinder with the bottom; and gunpowder and a hammering plate are sequentially arranged in the hollow cylinder with the bottom from top to bottom. Explosion vibration is carried out on the pile top so as to hammer the pile top and generate stress waves. Compared with a traditional drop hammer device, the drop hammer device has the advantages that the operation process is obviously simplified, and the use convenience is improved.
本申请提供的一种高应变检测锤击装置，属于锤击检测领域，包括：固定板、多个支撑桩、侧边抗拉结构、缓冲弹簧、空心带底圆柱体、火药和锤击板；所述固定板为平板形状；所述侧边抗拉结构包括多根抗拉钢筋，且对称分布在所述固定板的四周侧边；所述抗拉钢筋的上方与固定板固定，下方与所述支撑桩连接；所述固定板的正中心位置的下方固定连接所述缓冲弹簧，所述缓冲弹簧下部与倒置的所述空心带底圆柱体相连；所述空心带底圆柱体内部，从上到下依次装有火药和锤击板。本申请在桩顶进行爆振以锤击桩顶并产生应力波。相较于传统落锤装置，本发明装置显著简化了操作过程，提升了使用的便捷性。
