Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model provides a kind of non-rotating drilling rod protection device, including：It is enclosed on outside drilling rod 10
Drilling rod protective case 3；Upper limit clip 6 above drilling rod protective case 3；Lower limit clip positioned at the lower section of drilling rod protective case 3
1.Wherein, the external diameter of drilling rod 10 is less than the internal diameter of drilling rod protective case 3, in order to which drilling rod rotates relative to drilling rod protective case 3；The upper limit
Position clip 6 and lower limit clip 1 are fixedly set in outside drilling rod 10, it is impossible to are rotated relative to drilling rod 10.
It is arranged on specifically, the drilling rod protective case 3 of the present embodiment is removable outside drilling rod 10.As shown in Fig. 1 and 2, drilling rod
Protective case 3 includes：The protective case main body 31 made using high-abrasive material；The spring skeleton 32 being arranged in protective case main body.This
The drilling rod protective case 3 of embodiment is provided with hole, it is necessary to first with the special assembly and disassembly work shown in Fig. 3 when installing drilling rod protective case 3
Tool 8 opens drilling rod protective case 3, then drilling rod protective case 3 is enclosed on outside drilling rod 10, unclamps special mounting or dismounting tools 8, drilling rod protection
The self-return in the presence of spring skeleton 32 of set 3, hole closure.During implementation, drilling rod protective case 3 is used to form hole
Two folding ends set pin-and-hole respectively, when hole closes, the center centering of the pin-and-hole at two folding ends, by alloy steel pin 4
Pin-and-hole (plunger is upward) is inserted, so as to which drilling rod protective case 3 be locked.
The method that special mounting or dismounting tools 8 dismount drilling rod protective case 3 is as follows：Handle is clutched, opens special mounting or dismounting tools 8
And it is enclosed on outside drilling rod protective case 3；Handle is unclamped, two bills inwardly scratched of special mounting or dismounting tools 8 catch on drilling rod protective case 3
Two folding ends；Handle is clutched again, and drilling rod protective case 3 opens in the presence of special mounting or dismounting tools 8, by the drilling rod of opening
Protective case 3 is pulled down or is enclosed on drilling rod from drilling rod.
The present embodiment protective case main body 31 is made using the polyurethane of rational proportion, and rebound performance is good, in own resilience
And resilience is enclosed on outside drilling rod 10 in the presence of spring skeleton 32, even if alloy steel pin 4 damages, drilling rod protective case 3 also will not be light
Easily open and come off, the effect worn between drilling rod and sleeve pipe is reduced so as to serve well.Certainly, the protective case of the present embodiment
Main body 31 can also use the high-abrasive material for other prior arts that can reach the constructed effect of the present embodiment to make.
During implementation, because borehole depth is deepened, drilling rod 10 is formed by connecting by more piece unit drilling rod by tool joint 9, is led to
The external diameter of normal tool joint 9 is more than the external diameter of unit drilling rod, because drill pipe angle deviates sleeve pipe when being opened a window in order to avoid sidetracked hole
With pit shaft and tool joint 9 and sleeve pipe is directly contacted, the present embodiment close to tool joint 9 position set drilling rod protective case
3 (shown in Fig. 1), and the external diameter of drilling rod protective case 3 is more than the external diameter of tool joint 9.The present embodiment outside drilling rod 10 due to being set with
Drilling rod protective case 3, on the one hand make the hard grind of the steel between drilling rod 10 and sleeve pipe and steel damage be changed into drilling rod and drilling rod protective case 3 it
Between buffing damage, it is therefore prevented that the direct abrasion between drilling rod and sleeve pipe, reduce casing wear；On the other hand, due to polyurethane material
The coefficient of friction of material is far below steel and has good wearability (anti-wear performance of polyurethane is 400-500 times of cast iron) again,
Therefore transmission moment of torsion can be greatly reduced using drilling rod protective case 3, reduces drillling tool twisting off accident.
The quantity of the present embodiment installation drilling rod protective case 3 can be calculated according to well track concrete condition.
In addition, as shown in figure 1, the present embodiment be fixed on above and below drilling rod protective case 3 it is upper on drilling rod 10
Spacing clip 6 and lower limit clip 1, play a part of and support spacing to drilling rod protective case 3, be easy to drilling rod to be protected relative to drilling rod
Sheath 3 rotates.During installation, upper limit clip 6 and lower limit clip 1 reserve 1mm gap between drilling rod protective case 3 respectively.
The upper limit clip 6 and lower limit clip 1 of the present embodiment are made using aluminium alloy, in light weight, intensity is big.
The upper limit clip 6 and lower limit clip 1 of the present embodiment are sleeved on outside drilling rod also by removable mode.
As shown in figure 1, upper limit clip 6 and lower limit clip 1 are locked by the folding of hinge 2 by fastening bolt 5.Close
Page 2 and fastening bolt 5 are oppositely arranged.
Although above-mentioned elaborate to the utility model, the utility model not limited to this, the skill of the art
Art personnel can modify according to principle of the present utility model, therefore, all according to the various of principle of the present utility model progress
Modification all should be understood to fall into the scope of protection of the utility model.
