Specific embodiment
Further to illustrate the present invention to reach technical approach and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawings and embodiments to specific embodiment, structure, feature and its effect of the present invention, are described in detail as after.
As shown in Figure 1, the rotary drilling rig rod failure monitoring method of one embodiment of the invention is used to monitor whether rotary drilling rig is sent out
Green tape bar, rotary drilling rig include power head, the drilling rod on power head and the drill bit set on drilling rod end, the rotary drilling rig band
Bar monitoring method includes：
S100, judges whether the master winch of rotary drilling rig rises, if yes then enter step S300；Specifically, pass through master
Whether elevator upward leader pressure sensor detection master winch is rising.
S300 obtains the drill bit collapsing length S of rotary drilling rig and power head stress F；
S500, judges whether drill bit collapsing length S and power head stress F meet：
Li+1+Li+2+...+Ln<S≤Li+Li+1+Li+2+...Ln, and F<G+Ki+1+Ki+2...+Kn, if it is satisfied, then determining
Rod failure occurs for rotary drilling rig, wherein, drilling rod includes the pole that n roots are socketed successively, L1、L2、…、Li、…、LnIt is followed successively by first
The length of pole, second pole ..., i-th pole ..., n-th pole, weight of the G for power head assembly, K1、K2…Ki…Kn
The weight of n-th pole that first pole, second pole ... i-th is followed successively by with pole ..., first pole are most inner side section
Bar, n-th with pole be outermost pole.
By this rotary drilling rig rod failure monitoring method, can accurate measurements rotary drilling rig whether rod failure occurs, simultaneously as being
Determine whether rod failure by judging whether power head stress F meets correlated condition, sentence with detection master winch steel wire rope pulling force
It is disconnected that whether the method for rod failure is compared to relatively reliable, can exclude drill bit bottom be emptied, the improper feelings such as collapse hole or drill bit card hole
