The end of the end of section 311 and the extended segment 321 of the second locking cylinder 32, playing prevents the first stop spiral shell disk 41 and the second stop
The effect that spiral shell disk 42 is deviate from.
Further, as shown in Figure 1 and Figure 2, it is connected on the outside of 41 edge of the first stop spiral shell disk for driving the first stop
The first rotation that spiral shell disk 41 rotates is 71；It is connected on the outside of 42 edge of the second stop spiral shell disk for driving the rotation of the second stop spiral shell disk 42
The second rotation turned is 72.71 and second are revolved in first rotation plays 72 convenient for the first stop spiral shell disk 41 of driving and the second stop spiral shell disk
42 effect.
Further, multiple as shown in Fig. 2, being uniformly arranged in the circumferential direction multiple positioning male members 8 at the edge of orientation device 1
It positions male member 8 radially to extend to the external of orientation device 1, be opened up on the part that each positioning male member 8 extends orientation device 1
There is location hole 81.Positioning male member 8 and location hole 81 play the role of orientation device 1 being fixed on open hole well side.
As shown in Figure 4, Figure 5, the utility model also proposed a kind of safe lance composite structure of open hole well sidetracking, including peace
Full lance 9 and the safe lance of open hole well sidetracking as described above determine guiding device, and safe lance 9 is plugged in by safe lance insert port 211
Extend orientation device 1 in safe lance installation through-hole 21 and through safe lance extending port 212, along safe lance 9 on the side wall of safe lance 9
Axial direction offer the locked groove 91 of indent, continuous jagged safe lance is equipped in locked groove 91 and locks tooth 92, safe lance locks tooth 92
It is adapted with the one-way lock tooth 213 in safe lance installation through-hole 21, and at least part of safe lance lock tooth 92 and safe lance are pacified
One-way lock tooth 213 in dress through-hole 21 is meshed, the one-way lock toothing of formation.Stretch out safe lance 9 to safe lance
Mouth 212 unidirectionally advances, and prevents safe lance 9 from retreating to safe 211 direction of lance insert port.In this way, by safe lance lock tooth 92 with
The equipped one-way lock toothing formed of one-way lock tooth 213 can only unidirectionally advance so that safe lance can not be extracted backward, realize peace
Locating effect of the full lance after insertion orients cylinder.The positioning and support to safe lance are realized by orientation device, is reached to naked
Eye well side carries out the effect of fixed guiding.In the assembly of safe lance 9, one-way lock tooth 213 can form small with safe lance lock tooth 92
Deformation, to guarantee that safe lance 9 can move down, so that one-way lock tooth 213 and the lock cooperation of tooth 92 of safe lance guarantee safe lance 9
Safe lance installation through-hole 21 can unidirectionally be entered and can not extracted.
Further, as shown in Figure 4, Figure 5, the upper end of safe lance 9 is equipped with positioning round table 93, along 93 peripheral part of positioning round table
It is uniformly provided with several fixed holes 94.Safe lance 9 is fixed convenient for pile driving equipment by fixed hole 94.
Further, as shown in Figure 4, Figure 5, the lower end of safe lance 9 is in cone-shaped, in order to which safe lance 9 is inserted into open hole well
The soil layer of side wall.In the present embodiment, it is cone-shaped that the lower end of safe lance 9 is high in a side, another side is low, but this is practical new
Type is also not necessarily limited to this, and the lower end of safe lance 9 can also be in low cone-shaped in intermediate protrusion two sides, as long as can be convenient for safe lance 9
The sharp end for being inserted into any shape of the soil layer of open hole well side wall is encompassed by within the protection scope of the utility model.
When in use, it rotates the first stop spiral shell disk 41 and the second stop spiral shell disk 42 is close with the two sidewalls of orientation device 1 respectively
Fitting.By the frictional force between the first stop spiral shell disk 41 and the second stop spiral shell disk 42 and the two sidewalls of orientation device 1, so that first
Locking cylinder 31 and the second locking cylinder 32 are unable to complete rotation, and the orientation of orientation cylinder 2 thus can be completed.
After the angle position of safe lance 9 is adjusted, safe lance 9 is fixed on by the fixed hole 94 of safe lance and is beaten
On stake device, start the work of open hole well sidetracking, after safe lance 9 gradually protrudes into soil layer, one-way lock tooth 213 and safe lance lock tooth 92
Cooperation guarantees that safe lance 9 can unidirectionally enter safe lance installation through-hole 21 and can not extract, and has further functioned as to safe lance 9
Fixed effect.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
The detailed description of step, it should be understood that the foregoing is merely specific embodiment of the utility model, be not used to limit this reality
With novel protection scope.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it
