Further, described flexible coupling is provided with sealing member.
Further, connected by casing joint between casing main body.
Use and have the beneficial effects that produced by technique scheme:
The casing bit pulling out anchor cable described in the utility model, it is possible to according to the curve of actual anchor cable to be pulled out, pass through
For being rigidly connected or flexible connection carrys out matching existing anchor cable track between adjusting sleeve tube body, whole casing bit is by flexible connection
Realize self adaptation break-in, enable casing bit follow anchor cable to be pulled out move towards adjust the direction crept into so that it is the most suitable
Anchor cable direction to creep into, it is to avoid cut off anchor cable, get into anchoring section end always, after releasing anchor force, anchor cable entirety is extracted.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and specific embodiment
Utility model is carried out clear, complete description.
A kind of casing bit pulling out anchor cable as shown in Figure 1, it includes the unit head pin thread head for being connected with rig
1, interconnective some sections of casing main bodies 3 and drill bit 6, passes through between described casing main body 3 and described unit head pin thread head 1
Casing joint 2 is rigidly connected, and is threaded connection between unit head pin thread head 1, casing main body 3 and casing joint 2.
Between some sections of described casing main bodies 3, the curvature according to anchor cable 8 to be pulled out is set to flexible connection or is rigidly connected,
For flexible connection between described casing main body 3 and described drill bit 6.Concrete, see the track signal that Fig. 3 is anchor cable 8 to be pulled out
Figure, wherein X-axis represents anchor cable horizontal distance, and Y-axis represents anchor cable vertical dimension, and α is the actual angle of incidence of anchor cable.Anchor cable is at gravity
Effect under, track is similar to parabola, and front end curvature is relatively big, and for arching trajectory, rear end curvature is less, linearly, root
According to the Curvature varying of anchor cable to be pulled out in practice of construction, design for being rigidly connected or flexible connection between adjacent casing main body 3,
The length of casing main body 3 can be selected simultaneously according to practical situation, be used for enabling the preferably matching of whole casing bit to wait to pull out
The curve of anchor cable 8, whole casing bit realizes self adaptation break-in by flexible connection, enables casing bit to follow and waits to pull out
The moving towards of anchor cable 8 adjusts the direction crept into so that it is contains anchor cable always and creeps into, it is to avoid cuts off anchor cable.
Two casing main bodies 3 realize being rigidly connected by casing joint 2, and casing main body 3 is with casing joint 2 by screw thread even
Connect, realize flexible connection by flexible coupling.Described flexible coupling is provided with sealing member, in drilling process, needs at set
Pipe device injects mud, avoids revealing at flexible coupling mud by described sealing member.
For flexible connection between the casing main body 3 and described drill bit 6 of end.Concrete, see Fig. 2, described sleeve pipe
It is connected by flexible coupling between main body 3 with described drill bit 6, in described flexible coupling includes flexible coupling 4 and two flexibility
Joint 5, flexible nipple 5 described in two is symmetricly set in described flexible coupling 4 two ends, one of them flexible nipple 5 and institute
Stating casing main body 3 to be rigidly connected by screw thread, another flexible nipple 5 is rigidly connected by screw thread with described drill bit 6.Described
Flexible nipple 5 one end is arc-shaped outer surface, and flexible coupling 4 both sides are symmetrical and with described flexible nipple 5 arc
The arc-shaped inner surface that outer surface is suitable, described flexible coupling 4 arranges location with flexible nipple 5 left and right sides of side
Pin, makes the flexible nipple 5 of this side can swing up and down in flexible coupling 4, and described flexible coupling 4 is scratched with opposite side
Property nipple about 5 both sides arrange alignment pin, make the flexible nipple 5 of this side to swing.Scratch described in as in figure 2 it is shown,
Property coupling 4 on relevant position hole 7, location is set, on flexible nipple 5, correspondence position arranges blind hole, hole 7, described location He
Alignment pin is set between blind hole.
