An impactor gas distribution device and a matching impactor

Abstract

A gas distribution device for an impactor and a matching impactor, including a gas distribution rod, the gas distribution rod is provided with a gas distribution rod core to connect the air inlet channel of the impactor to the air chamber passage at the rear of the impactor, and the gas distribution rod The core is provided with air intake passages of different cross sections and rotatable adjustment positions, and the air distribution rod has air holes of different flow areas, angles and positions. A rotary locking round key is provided between the gas distribution rod and the gas distribution rod core. According to different construction hole depths and rock hardness conditions, the relative position of the air distribution rod core and the air distribution rod can be rotated to connect different air intake channels, so as to change the air consumption, change the piston stroke, and thus change the impact energy of the piston and the frequency of the impactor. Purpose. The structure of the device is simple, and the impactor can be adjusted according to changes in the external environment such as hole depth and rock hardness, and the performance parameters of the impactor can be changed to meet the needs of different hole depths and different use environments.

Description

Technical field [0001] The present invention relates to an impactor gas supply device and a supporting impactor. Background technique [0002] The drilling operation of the sub-hole drill system is currently the high-efficiency high-quality complex operation technology used in the open-air drilling blasting, well, geothermal and deep well drilling industry. Deep, covering layer thickness, rock hardness different work environments, while different operating environments have different performance parameters, and thus when using an impactor, when the holes are not deep or the amount of rock is not hard. The impact of the impact has a lot of money; when the hole is deep, the amount of gas is inadequate when the rock is hard, and the impact work is not enough. The current implementation is that the reserve of different air consumables, the impact of different impact works should respond, although this program will meet the requirements of the work, but the cost of the reserve impact ...

Problems solved by technology

[0002] The drilling operation of the down-the-hole drilling system is an efficient and high-quality hole-forming operation technology commonly used in the surface drilling and blasting, water well, geothermal and deep well drilling industries. However, the conventional drilling tools used in the down-the-hole drilling system often have to face The depth, cover layer thickness, and rock hardness are different in the working environment, and the performance parameters required by different working environments are different. Therefore, when using an impactor to deal with it, when the hole is not deep or the rock is not hard The waste of impact energy is large; when the hole is deep and the rock is hard, the gas volume is insufficient and the impact energy is not enough

The currently implemented measures are to store impactors with different air consumption and different impact energy to deal with this situation. Although this solution can rarely meet the requirements of the construction method, the cost of the required reserve impactors is too high, especially in the face of different construction site, and it is more obvious when the distance is far
