Device for measuring angle of blast hole

The utility model discloses a device for measuring the angle of a blast hole, which relates to the technical field of blast hole angle measurement, and is characterized in that a main ruler is put into a blast hole to be fixed through an auxiliary jacking device, and after a pendulum bob naturally stops swinging stably, the scale of a pointer on a protractor is read to obtain the dip angle of the blast hole; and the azimuth angle on the compass is read to obtain the azimuth angle of the blast hole, so that the dip angle and the azimuth angle of the blast hole can be intuitively and accurately measured, the measurement cost is reduced, and the measurement efficiency is improved. 本实用新型公开了一种测量炮孔角度的装置，涉及炮孔角度测量技术领域，所提出的测量炮孔角度的装置，通过辅助顶紧装置将主尺放入炮孔中固定，等待摆锤自然停摆稳定，读取指针在量角器上的刻度，得到炮孔倾角，读取指南针上的方位角，得到炮孔方位角，从而可以直观、准确的测量出炮孔倾角及方位角，降低测量成本，提高测量效率。
