Fixing device used for engineering blasting and having damping function

Abstract

The invention discloses a fixing device used for engineering blasting and having a damping function. The fixing device comprises adjusting screw rods, limiting plates, an installing bottom plate and chucking clamps. A damping gasket is arranged at the bottom end of the installing bottom plate. Fixing plates are fixed to the two ends of the top of the installing bottom plate correspondingly. The adjusting screw rods are arranged on the fixing plates in a transverse penetrating manner correspondingly. A dynamite pack main body is arranged at the center position of the top of the installing bottom plate. Fixing blocks are fixed to the ends, close to the dynamite pack main body, of the adjusting screw rods correspondingly. The ends, close to the dynamite pack main body, of the limiting platesare connected with the dynamite pack main body. Irregular protrusions are uniformly arranged at the ends, close to the dynamite pack main body, of the limiting plates correspondingly. According to thefixing device used for engineering blasting and having the damping function, the installing bottom plate is installed, ground piles are fixed to the edges of the installing bottom plate and can be conveniently inserted into a wall body or a mountain body to be exploded for carrying out fixed connecting, barbs are uniformly arranged on the ground piles, and deep inserting is facilitated.

Description

technical field [0001] The invention relates to the technical field of fixing devices, in particular to a fixing device for engineering blasting with a shock absorbing function. Background technique [0002] China's decades of economic construction has produced many blasting projects. In large-scale projects such as railways, mines, and reservoirs, the role of blasting technology is very important. Although blasting technology was introduced from the Soviet Union, blasting engineering technology has evolved with social production practice. Developed, explosives are the energy source of blasting engineering. The explosives used in engineering blasting are called industrial explosives. During blasting, explosives need to be fixed. [0003] Most of the existing engineering explosive blasting devices have simple structures and single functions, and are not convenient for fixed connection with the mountain or wall to be blasted. The safety is not high, and the clamping fixture o...
