Bit distributing device for cylindrical drill

Abstract

The invention provides a bit distributing device for a cylindrical drill. The bit distributing device is used for determining positions of bits on the cylindrical drill and comprises a clamp and a regulating component. The clamp comprises a first clamp and a second clamp, wherein the first clamp is used for fixing the regulating component on the cylindrical drill, and the second clamp is used for fixing the bits on the regulating component. The regulating component comprises tip height regulating parts used for regulating the height of tips of the bits relative to an end face of the cylindrical drill, the tip height regulating parts include a regulating bar arranged vertically and a cross arm arranged horizontally, the first clamp is connected to the lower portion of the regulating bar, the cross arm is connected to the regulating bar in a manner of moving along the regulating bar up and down, and the second clamp is arranged on the cross arm. By the bit distributing device for the cylindrical drill, rotation diameter, tip height, tunneling angle and drift angle of the bits can be regulated, and the bits can be positioned accurately. In addition, the bit distributing device for the cylindrical drill brings convenience for workers to operate, and accordingly, labor intensity of the workers is lowered.

Description

technical field [0001] The invention relates to the field of mechanical fixtures, in particular to a tooth distributing device for a barrel drill. Background technique [0002] The tooth placement quality of the barrel drill of the rotary drilling rig directly affects the construction efficiency of the rotary drilling rig and the life of the pick, which in turn affects the construction cost. Therefore, it is very important to improve the tooth placement quality of the barrel drill. At present, the arrangement of teeth on the barrel drill involves multiple position parameters, including the rotation diameter of the pick, the height of the tooth tip, the angle of entry and deflection, and for the outer, middle and inner teeth, these parameters are also no the same. In actual production, improving the tooth placement quality of the barrel drill means improving the accuracy of these four position parameters during tooth placement. [0003] However, at present, during the weldi...

AI Technical Summary

Problems solved by technology

[0004] 1. With the help of visual inspection and a simple tape measure, it is difficult to achieve precise positioning of the picks by manual tooth placement, and sometimes there will be large errors

[0005] 2. The quality of teeth placement of workers with different experience is different, and the quality of teeth placement of the same worker at different working hours is also different. These factors directly lead to uneven quality and poor consistency of barrel drills

[0006] 3. Since the tooth placement process involves many positioning parameters, it is difficult to coordinate all parameters before, so the work efficiency of manual tooth placement is relatively low, which increases the production cost
