Detailed Description
A drilling device for reinforcing an anchor rod on a shallow slope surface is characterized by comprising a fixing part 1, a hexagonal drill rod 2, a circular truncated cone windmill drill bit 3 and a hexagonal positioning drill bit 4; the fixing part 1 is arranged at the rear end of the hexagonal drill rod 2, and the circular truncated cone windmill drill bit 3 is arranged at the front end of the hexagonal drill rod 2; the front end of the circular truncated cone windmill drill bit 3 is provided with a hexagonal positioning drill bit 4;
The hexagonal drill rod 2 is arranged on the shaft centers of the fixing part 1 and the circular truncated cone windmill drill bit 3; the hexagonal positioning drill bit 4 is arranged on the shaft center of the circular truncated cone windmill drill bit 3;
The axes of the two ends of the fixing part 1 and the circular truncated cone windmill drill bit 3 are provided with internal threads; the two ends of the hexagonal drill rod 2 are provided with external threads at the rear end of the hexagonal positioning drill bit 4, and the internal threads and the external threads are matched with each other; the rear end of the fixing part 1 is connected with a driving device 8, and the front end of the fixing part is connected with the hexagonal drill rod 2; the rear end of the circular truncated cone windmill drill bit 3 is connected with the hexagonal drill rod 2, and the front end of the circular truncated cone windmill drill bit is connected with the hexagonal positioning drill bit 4; a slag discharge groove 5 is formed in the wall of the hexagonal positioning drill bit 4;
The front end of the circular truncated cone windmill drill bit 3 is provided with a drill tooth I6; the front end of the hexagonal positioning drill bit 4 is provided with drill teeth II 7.
in the present example, the cemented carbide insert type, shape and dimensions are as follows:
and combining and arranging the hard alloy blades.
(1) Combining: the advantages of the wood saw teeth and the wood planer tool are mutually complemented and combined according to the functions of the wood saw teeth and the wood planer tool respectively.
(2) Arranging:
arranging requirements on a vertical plane: the first type alloy is 1 to 1.5mm higher than the second type alloy.
Second, the requirement of arrangement on the plane: the alloys of different types are required to be arranged according to the staggered seam principle, and the most edge of one alloy of two types is deviated by about 2.5mm towards the outer edge.
As shown in fig. 2, 9 pieces of I-type alloy (YW 2C 116) are vertically arranged and staggered left and right; 6 II type alloys (YG 8T 3-97001) are arranged in a staggered manner from side to side; the I type alloy is 1-1.5 mm higher than the II type alloy. The outer diameter of the disc is 7.5 mm.
