Specific embodiment
Fig. 1 is existing structure schematic diagram 1；Fig. 2 is schematic diagram of the three-dimensional structure；Fig. 3 is erection device structural representation
Figure；Fig. 4 is holder structure schematic diagram；
Front-rear direction is the axial direction of drilling rod in Fig. 1 and Fig. 2 in the present embodiment；
As shown in Figure 1, existing drilling machine includes rack 1, it can slide back and forth in rack and be provided with power assembly 2, power assembly
The transmission of driving front side is combined with chuck I 9, and the front side of chuck I is provided with chuck II 10, and chuck II is fixedly connected in rack,
It is connected with water pigtail 8 on rear side of power assembly, kelly 3 is provided in power assembly and rotation is driven by power assembly, it is main
Dynamic drilling rod is stuck in chuck I 9；
There are two types of upper drill method, rear stacks mode and intermediate stacks modes for structure tool, as shown in Figure 1, newly-increased
Drilling rod 13 bores on being located on rear side of power assembly, is rear stacks mode, newly-increased drilling rod be located at position 12 brill be in bore indirectly
Bar mode；
When using rear stacks mode, kelly is connect with drilling rod in hole, and newly-increased drilling rod is connected on rear side of kelly,
First water pigtail 8 is removed, man-hour manually hand-held increases drilling rod 13 newly for the female thread of pin thread alignment kelly, and drilling rod is hollow tubular structure,
Pin thread is to be connected to the external thread structure that drilling rod rear end is in cone, and female thread is in positioned at drilling rod front end interior spiral shell compatible with pin thread
