Detailed Description
Reference is made to the accompanying drawings. The drill rod of the utility model comprises a plurality of sections of common section drill rods and a section of first section drill rod.
The common section drill rod consists of a middle section 2, an external thread section 1 and an internal thread section 3 which are positioned at two ends of the middle section, wherein the middle section 2 is provided with a pin hole 4; wherein the common section drill rods of adjacent sections are detachably connected by an external threaded section 1 of one common section drill rod and an internal threaded section 3 of another common section drill rod.
The first section of drill rod comprises an external thread section 5, a transition section 6, a ball 7 and a head conical body 8, wherein the external thread section 5, the transition section 6 and the head conical body 8 share the same central line, and the central line passes through the center of the ball 7; the external thread section 5 is arranged at the tail part of the transition section 6 and can be a thread section at the tail part of the same rod, the front end of the transition section 6 is welded with one side of the round ball 7, and the other side of the round ball 7 is welded with the conical body 8; the external thread section of the first section of drill rod can be connected with the internal thread of the common section. The outer diameter of the ball is larger than that of the common section of drill rod.
The implementation mode is as follows:
1 when the power system is connected to the squeezing and expanding device through a plurality of sections of common section drill rods, one section of common section drill rod is firstly inserted into the power system, a pin bolt is inserted into a pin hole 4 to connect the two sections of common section drill rods, one exposed end of each drill rod is connected with the other section of common section drill rod, the common section drill rods are sequentially connected to the squeezing and expanding device, and then the pin bolt is inserted into the pin hole 4 of the section of drill rod to connect. This connection can be used to pull the companding device.
