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 is mainly made up of dynamic head main spindle 1, floating pipe nipple 2, spline housing 3, ball-type water axle 4, wear ring the 5, the oneth O RunddichtringO the 6, the 2nd O RunddichtringO 7, gland 8, baffle plate 9, water seal 10 and liner 11.
As it is shown in figure 1, coupled by spline housing 3 between described dynamic head main spindle 1 and floating pipe nipple 2, owing to floating pipe nipple 2 can move axially as required in spline housing 3, therefore between floating pipe nipple 2 and spline housing 3, use matched in clearance；It is tightly connected by hollow ball-type water axle 4 between endoporus and the endoporus of floating pipe nipple 2 of dynamic head main spindle 1；Described ball-type water axle 4 first end is set to sphere, and the 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 is mainly made up of wear ring the 5, the oneth O RunddichtringO the 6, the 2nd O RunddichtringO 7 and gland 8, the connection end 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 anterior and spherical concave surface of described ball-type water axle 4 first end sphere contacts cooperation, 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 threadeded with dynamic head main spindle 1, and gland 8 compresses the rear portion of ball-type water axle 4 first end sphere, and the position that gland 8 contacts sphere is also set to spherical concave surface.
The first sealing connecting component in figure is static seal structure, owing to displacement and the scope of ball-type water axle 4 first end sphere are the least, uses static seal structure can meet requirement.Described wear ring 5 one aspect can position the position of ball-type water axle 4, on the other hand can improve the life-span of sphere.O RunddichtringO the 6, the 2nd O RunddichtringO 7 being arranged on the interior outside of wear ring 5 may insure that favorable sealing property.Described gland 8 is to be connected to threadably on dynamic head main spindle 1, and gland 8 has adjustability to the thrust of sphere.
As shown in Figure 1, in the embodiment of the present invention, described second sealing connecting component is mainly made up of baffle plate 9, water seal 10 and liner 11, the connection end 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 is fastenedly connected with floating pipe nipple 2, and baffle plate 9 compresses water seal 10.In the present embodiment, described water seal 10 preferably employs V-arrangement folder cloth circle.
The second sealing connecting component in Fig. 1 is movable sealing structure, and owing to there being relative movement regularly between the face of cylinder and the floating pipe nipple 2 of ball-type water axle 4 second end, and displacement and scope man are relatively big, so present invention employs movable sealing structure.
Operation principle and the course of work of the present invention are as follows:
When engineering construction, floating pipe nipple 2 docks with drilling rod, drilling rod can transmit bigger pulling force and moment of torsion in boring procedure, owing to there is gap between floating pipe nipple 2 and spline housing 3, therefore floating pipe nipple 2 can offset on a small quantity towards gap, and the face of cylinder of ball-type water axle 4 second end also can produce direction skew accordingly.Now the sphere of ball-type water axle 4 first end has just played effect, and once the face of cylinder of the second end produces skew, and the sphere of the first end just can the least scope rotate, and travel direction adjusts；Make ball-type water axle 4 can keep being reliably connected with dynamic head main spindle 1 all the time in floating pipe nipple 2 axial movement, can freely swing within the specific limits again；When floating pipe nipple 2 is formed certain angle by relatively large load with dynamic head main spindle 1, ball-type water axle 4 also will not rupture due to bigger shearing, and overall mechanical property is good, can well tackle the emergency case in construction process.Meanwhile, dynamic head main spindle 1 also will not be affected.
It addition, described ball-type water axle 4 is hollow-core construction, the mud so produced in engineering construction persistently can carry inside floating pipe nipple 2, ball-type water axle 4 and dynamic head main spindle 1, does not affect mud and passes through.
