Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings.
[0013] see figure 1 and figure 2 A mechatronic large-aperture drilling device shown includes a cylindrical shell 1 fixed on upper and lower fixing brackets 8, and its structural characteristics are:
[0014] A plurality of gear motors 2 are equidistantly arranged on the circumference of the inner wall of the cylindrical shell 1, a gear turntable 3 is provided on one end, and a cylindrical tube that is connected with a fixed runner 10 at the other end is arranged on the cylindrical shell 1. Inside; the gear of the gear turntable 3 on the cylindrical tube meshes with the gears of a plurality of gear motors 2, and the fixed runner 10 connected with the other end of the cylindrical tube cooperates with the inner wall of the cylindrical shell 1; the fixed runner The function is to support the gear turntable and rotate with the gear turntable.
[0015] The said gear turn...

The invention discloses an electromechanical integration large-aperture drilling device which comprises a cylinder shell which is fixed on upper and lower fixing brackets; the inner wall of the cylinder shell is provided with a plurality of gear motors; a gear rotary disc is arranged at one end part of each gear motor; the other end part of each gear motor and a cylinder pipe which is connected with a fixed rotary wheel in a matching way are arranged inside the cylinder shell; a gear which is arranged on the gear rotary disc of the cylinder pipe is engaged with gears of the plurality of gear motors; the fixed rotary wheel which is connected with the other end part of the cylinder pipe in the matching way is matched with the inner wall of the cylinder shell; the gear rotary disc is connected with a cutter mounting frame in a positioning way, wherein the diameter of the cutter mounting frame is the same as that of the gear rotary disc; the cutter mounting frame is connected with a plurality of electric rotary tool bits and a plurality of fixed tool bits in a positioning way; and a pressure sensor is arranged at the back part of each fixed tool bit. In the invention, the gear rotary disc is provided with the cutter mounting frame and the diameter of the cutter mounting frame is the same as that of the gear rotary disc, and the cutter mounting frame is connected with the pluralityof electric rotary tool bits and the plurality of fixed tool bits in a positioning way, so that holes with large apertures can be drilled, and rock holes with high hardness can be drilled.
Description
technical field [0001] The invention relates to a drilling machine, in particular to an electromechanical integrated large-aperture drilling device. technical background [0002] The drilling device generally adopts a drill bit, that is, the front part of the twisted metal rod is processed into a certain angle for drilling, and in order to improve the hardness, an alloy material with high hardness is installed on the front part. However, none of them can perform large-diameter operations, especially when drilling diameters above 1 meter, and there are no such large drilling rigs. Contents of the invention [0003] The object of the present invention is to provide an electromechanical integrated large-aperture drilling device, which can not only drill large-aperture holes, but also drill rock caves with high hardness. [0004] A mechatronic large-aperture drilling device according to the present invention includes cylindrical shells fixed on upper and lower fixing brackets...
