Embodiment Construction

[0028] Such as Figure 1 to Figure 4 As shown, the automatic pipe twister 10 of the vertical shaft drilling rig utilizing the punching mechanism of the present invention includes a screwing mechanism 1, a clamping mechanism 2, a punching mechanism 3 of the present invention, a base 4 and an upper cover 5. Wherein, the clamping mechanism 1 is used to clamp the bottom of the drill rod, and the unscrewing mechanism 2 is used to rotate the upper drill rod 20 to unload the upper drill rod 40 from the lower drill rod 20 or to screw the upper drill rod 20 into the lower drill rod 40. The punching mechanism 3 is used to give the unscrewing mechanism 1 an instantaneous impact force, so that the unscrewing mechanism 1 has enough power to unscrew the upper drill pipe 20 from the lower drill pipe 40 . The buckle mechanism 3 can also be used for locking after the upper drill pipe 20 is screwed into the lower drill pipe 40 by adjusting the direction of the pawl, so as to ensure the locking...

Abstract

The invention provides a punching mechanism of an automatic twisting machine of a spindle-type drilling machine. The automatic twisting machine comprises a dismounting mechanism, a clamping mechanism and a punching mechanism, wherein the dismounting mechanism comprises a gear wheel for driving an upper-section drill rod to rotate; the punching mechanism comprises a linear oil cylinder, a lever and at least one elastic pawl device; the lever comprises a connecting part and an annular rotating part which are integrally arranged; the connecting part is connected with a linear piston of the linear oil cylinder; the annular rotating part is adjacent to and coaxial with the gear wheel; the elastic pawl device is arranged between the annular rotating part and the gear wheel; and the elastic pawl device engages the annular rotating part and the gear wheel in one state, and disengages the annular rotating part and the gear wheel in another state. The punching mechanism has the advantages of simple and reasonable structure, large impact force, small occupation area and low energy consumption.

Description

【Technical field】 [0001] The invention relates to an automatic pipe twisting machine for a vertical shaft drilling rig, in particular to a punching mechanism for an automatic pipe twisting machine for a vertical shaft drilling machine. 【Background technique】 [0002] Vertical shaft drilling rig is a rotary drilling rig commonly used in geological drilling. The rotary mechanism of this kind of drilling rig has a long vertical shaft (about 1 meter), which is used to drive the drilling tool to rotate, realize feeding and guide the drilling tool, so it is called vertical shaft drilling rig. It can drill vertical holes and a certain range of inclined holes in rocks of various hardness. The guiding effect of the vertical shaft is particularly significant when drilling shallow and inclined holes. [0003] The pipe wrench is a kind of machine used to unscrew the drill pipe when the drilling tool is tripped in geological drilling. It can replace manpower to unscrew and unload the ...
