Enough accommodate the pipeline.When need to polish pipeline when, open the open-close type outline border 32, pipeline passed through into the space with by institute
Polishing nose is stated to be arranged on the pipeline.Polishing nose is fixed to before pipeline, will be opened and is opened with formula outline border, by polishing nose
After being installed on pipeline, closing open with formula outline border, realize polishing nose and the mechanical obvolvent for being polished pipeline at this time.Due to portion
It is in charge of line, such as the end of open flow straight pipe-line is provided with flange.The outer diameter of flange is larger, and closed type workpiece polishing mechanism is difficult to across putting
The flange position of straight pipe-line is sprayed, therefore, the polishing nose of open-close type is arranged in the present invention, and readily polishing nose can be arranged
On pipeline.
The inside of the open-close type outline border 32 is arranged in the oblique roller set 33, as shown in Figure 3.The oblique roller set
33 include multiple oblique rollers.The radial diameter of plane and the pipeline where the oblique roller is a certain included angle.I.e.
The oblique roller and pipeline out of plumb.The oblique roller being arranged can rely on pipeline and polishing nose in pipeline rotation process
Between frictional force drives polishing nose along pipeline axial advancement.
In the present embodiment, the open-close type outline border can be set to the concave outline border of one piece of entirety.Open-close type outline border
Side and the side of headstock connect, and the other side of the other side and headstock, which opens and closes, to be arranged.The open-close type outline border can also be set
It is set to the first outline border 32a and the second outline border 32b by mutual mirror settings, as shown in Figure 3.
In the present embodiment, the arrangement of the connection type and oblique roller of the open-close type outline border and headstock is such as
Shown in Fig. 5 a.Hinge 51 can be set in the bottom of the open-close type outline border 50 (enlarged drawing of hinge is as shown in Figure 5 b).Pass through
The open-close type outline border 50 is connect by hinge 51 with headstock.Hinge 51 is fixed by bolt.The open-close type outline border 50
Inside mounting plate 52 can be set.The both ends of the mounting plate 52 are provided with threaded hole 52a, as shown in Figure 5 c.Pass through institute
State the inside that the mounting plate 52 can be fixed at the open-close type outline border 50 by threaded hole 52a.The mounting plate 52 is also
It is provided with the through-hole 52b that multiple groups are obliquely installed, every group of through-hole 52b is for installing the oblique roller 53.The oblique roller 53
Enlarged drawing as fig 5d.The oblique roller 53 is provided with the peace that can be fixed at oblique roller on mounting plate 52
Dress portion.The surface of the mounting portion is provided with the mounting hole being equipped with every group of through-hole.It can be bolted.For
Increase the power that polishing nose advances, can arrange multiple oblique rollers.For example, can be set under each polishing mounting rack
3 or more oblique rollers.For example, as shown in figure 5,5 oblique rollers of setting.
In the present embodiment, as shown in figure 4, the first grinding wheel mounting rack 40a and the second grinding wheel mounting rack 41a can
To be connect by elastic hinge 42 with headstock hinge.Elastic hinge 42 can provide upward power to grinding wheel.In view of quilt
Polishing pipeline surface has its outer diameter after the impurity such as cement and soil that can change, and fixed grinding wheel is difficult to meet the requirements,
Therefore the present invention substitutes fixed grinding wheel using floating type grinding wheel, by the effect of elastic hinge 42, enables grinding wheel
Bus real-time contact that is enough and being polished pipeline, avoids the generation of polishing blind area.
In the present embodiment, the first grinding wheel mounting rack and the second grinding wheel mounting rack can be U-shaped structure.Such as figure
Shown in 6.The two sides of grinding wheel 61 are arranged in the both ends of the grinding wheel mounting rack 60 of the U-shaped structure.The side of grinding wheel 61 is set
It is equipped with driver 62, the other end is provided with the mandrel of fixed grinding wheel.Centre bore is provided in the middle part of the grinding wheel 61.The drive
The axis of dynamic device can pass through one end of the grinding wheel mounting rack and grinding wheel 61 is used to that grinding wheel to be driven to rotate.
In the present embodiment, since the oilfield environment of open flow straight pipe-line work has requirement of explosion proof, existing hand sand dress
It sets and easily causes spark, therefore, first sanding component can also include the first drive enclosure, outside first driver
Shell places first driver for sealing, and second sanding component can also include the second drive enclosure, and described the
Two drive enclosures place second driver for sealing.The driving electrodes can be fire-proof motor.By driving device
Be sealed in actuator housing, will not because of motor spark and cause fire, improve scene safety；In the present embodiment
In, if the grinding wheel that setting is single, the track that pipeline is polished are as shown in Figure 7.It rotates in place, polishes when being polished pipeline 70
Head straight ahead, grinding wheel are contacted with one section of bus of pipeline 70, and grinding wheel is spiral shell relative to the motion profile of pipeline at this time
Track is revolved, the area of covering is one section of coil region, as shown in fig. 7, there is one section of blind area between neighboring spiral.The present invention adopts
Realize that all standing is polished with the mode of two grinding wheel complementations, two grinding wheels are respectively in circumferential Difference angles, i.e., and two
The end face of a grinding wheel is not in the same plane.The track of second grinding wheel covers the blind area of first grinding wheel track, both
Grinding efficiency is improved, while realizing the automation polishing of non-blind area.
In the present embodiment, as shown in figure 8, while in order to guarantee structural strength, mitigate the weight of entire polishing nose,
The headstock can use rectangular square tube 80 and is welded to form.As shown in figure 8, the headstock can be tetrahedron knot
One opposite sides of structure, the headstock can be set to dies.Another opposite sides of the headstock
It can be set to " mouth " font structure.The lower end of " mouth " font structure is arranged two inclined rectangular square tubes and is used to support machine
Head frame.
In the present embodiment, the pipeline can be any pipeline for needing to polish.It is particularly suitable for oil-gas mining process
In blooie pipe pipeline.
In the present embodiment, since existing grinding device can generate a large amount of dust, environment is polluted.Therefore, the polishing
Capsul can also be arranged in device, and the capsul can be sealed the polishing nose in bruting process.The present invention is filled
The collection for being easily achieved dust after sealing is set, pollution of the dust to environment is avoided, it can be to avoid harsh environments to behaviour
Body harm caused by workmanship
