The invention discloses a device and a method for protecting a blasting vibration test instrument. The device comprises a hemispherical spherical shell made of a steel wire rope core conveying belt onthe ground surface, an arc-shaped steel bar is fixed to the outer side of the hemispherical spherical shell, a steel wire rope is arranged at the 1 / 4 position of the arc-shaped steel bar, a spring isarranged at the tail end of the steel wire rope, the tail end of the spring is connected with an anchor, and the lower end of the anchor is nailed into the ground surface; the inner layer of the device comprises a hemispherical rigid spherical shell. The device for protecting the blasting vibration testing instrument can well protect the blasting vibration testing instrument, prevent the blastingvibration testing instrument from being smashed by blasting flying stones and is low in manufacturing cost, the scrapped steel wire rope core conveying belt for mine ore transportation is adopted, waste is recycled, resources are saved, and the environment is protected. The method provided by the invention is simple and practical, can greatly reduce the installation frequency of the explosion vibration tester device, and saves the installation time.
Description
technical field [0001] The invention relates to a device and method for protecting a blasting vibration testing instrument, belonging to the technical field of blasting engineering. Background technique [0002] Flying stones will be generated in blasting engineering. Although there is a certain safety allowable distance for the protection of flying stones, some flying stones will still be thrown from poorly blocked blast holes and medium cracks (seams), exceeding the safety allowable distance. Since the blasting vibrometer is a high-precision instrument and expensive, in order to prevent the blasting flying stone from damaging the blasting vibrometer, it needs to be protected safely. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a device and method for protecting the blasting vibration tester, which can not only protect the blasting vibration tester well, but also reduce the installation...
