Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the non-excavation pipe-laying drilling rig unit head floating installation in embodiment forms primarily of dynamic head main spindle 1, float pipe nipple 2, spline housing 3, ball-type water axle 4, wear ring 5, an O RunddichtringO 6, the 2nd O RunddichtringO 7, gland 8, baffle plate 9, water seal 10 and liner 11.
As shown in Figure 1, connected by spline housing 3 between described dynamic head main spindle 1 with floating pipe nipple 2, because floating pipe nipple 2 can move axially as required in spline housing 3, therefore float and adopt matched in clearance between pipe nipple 2 and spline housing 3; Be tightly connected by hollow ball-type water axle 4 between the endoporus of dynamic head main spindle 1 and the endoporus of floating pipe nipple 2; Described ball-type water axle 4 first end is set to sphere, and first end is connected with dynamic head main spindle 1 by the first sealing connecting component; Described ball-type water axle 4 second end is set to the face of cylinder, and the second end is connected with floating pipe nipple 2 by the second sealing connecting component.
As shown in Figure 1, in the embodiment of the present invention, described first sealing connecting component forms primarily of wear ring 5, an O RunddichtringO 6, the 2nd O RunddichtringO 7 and gland 8, the link of described dynamic head main spindle 1 endoporus is provided with the first installation cavity 1a, described wear ring 5 is contained in the bottom of the first installation cavity 1a, arranges an O RunddichtringO 6 between wear ring 5 periphery wall and the first installation cavity 1a inner hole wall; The front portion of described wear ring 5 endoporus is set to spherical concave surface, and the front portion of described ball-type water axle 4 first end sphere contacts with spherical concave surface and coordinates, and arranges the 2nd O RunddichtringO 7 between sphere and spherical concave surface; Described gland 8 is sleeved on ball-type water axle 4 first end, and gland 8 is threaded with dynamic head main spindle 1, and gland 8 compresses the rear portion of ball-type water axle 4 first end sphere, and position gland 8 contacting sphere is also set to spherical concave surface.
The first sealing connecting component in figure is static seal structure, due to the displacement of ball-type water axle 4 first end sphere and scope very little, adopt static seal structure to meet the demands.The position of ball-type water axle 4 can be located in described wear ring 5 one aspect, can improve the life-span of sphere on the other hand.The O RunddichtringO 6, the 2nd O RunddichtringO 7 that are arranged on outside in wear ring 5 can guarantee favorable sealing property.Described gland 8 is that the mode be threaded is connected on dynamic head main spindle 1, and the thrust of gland 8 pairs of spheres has adjustability.
As shown in Figure 1, in the embodiment of the present invention, described second sealing connecting component forms primarily of baffle plate 9, water seal 10 and liner 11, the link of described floating pipe nipple 2 endoporus is provided with the second installation cavity 2a, described liner 11 is contained in the bottom of the second installation cavity 2a, described water seal 10 is arranged on outside liner 11, and ball-type water axle 4 second end face of cylinder sealing shroud is contained in water seal 10; Described baffle plate 9 is sleeved on ball-type water axle 4 second end, and baffle plate 9 screw and floating pipe nipple 2 are fastenedly connected, and baffle plate 9 compresses water seal 10.In the present embodiment, described water seal 10 preferably adopts V-arrangement folder cloth circle.
The second sealing connecting component in Fig. 1 is movable sealing structure, and owing to having relative movement regularly between the face of cylinder of ball-type water axle 4 second end and floating pipe nipple 2, and displacement and scope man are comparatively large, so present invention employs movable sealing structure.
Operating principle of the present invention and the course of work as follows:
When engineering construction, the pipe nipple 2 that floats docks with drilling rod, drilling rod can transmit larger pulling force and moment of torsion in boring procedure, owing to there is gap between floating pipe nipple 2 and spline housing 3, therefore the pipe nipple 2 that floats can offset on a small quantity towards gap, and the face of cylinder of ball-type water axle 4 second end also can the skew of corresponding generation direction.Now the sphere of ball-type water axle 4 first end has just played effect, once the face of cylinder of the second end produces skew, the sphere of first end just can rotate in time among a small circle, and travel direction adjusts; Make ball-type water axle 4 can keep reliable with dynamic head main spindle 1 all the time in floating pipe nipple 2 axial movement to be connected, can freely swing within the specific limits again; Floating pipe nipple 2 be subject to comparatively heavy load and form certain angle with dynamic head main spindle 1 time, ball-type water axle 4 also can not rupture due to larger shearing, and overall mechanical property is good, well can tackle the emergency case in construction process.Meanwhile, dynamic head main spindle 1 also can not be affected.
In addition, described ball-type water axle 4 is hollow-core construction, and the mud produced in engineering construction like this can continue conveying in floating pipe nipple 2, ball-type water axle 4 and dynamic head main spindle 1 inside, does not affect mud and passes through.
