Endless means component, i.e. O-ring sealing ring, the retaining ring local motion.
Further, the pressure oil is in shape to be stressed by the oil connection connected pipes, the pressure oil
State, oil pipe connection external hydraulic device, the final stress of pressure oil.
Further, the leading truck installation is oriented to the side of plugging mechanism, shows triangle, the effect of this shape
It is preferably to enter in pipeline.
Further, the directive wheel is installed on two vertex positions of the leading truck, and the directive wheel revolves for activity
The rubber or rigid plastics wheel turned, the effect of directive wheel are to avoid the guiding plugging mechanism from touching to produce when block-up position
Direct friction.
Further, the edge of a knife is the sharp sawtooth of metal being welded on below fixed mechanism, and the effect of the edge of a knife is lower stifled
When cutting pipes.
Specific implementation step is：During closure, internal-expansion type block head is placed in pipeline, is such as run into inner-walls of duct and is got rusty
Uneven, plugging leather cup can not be bonded inner-walls of duct completely, therefore can produce the situation of gas leakage；Pass through the utility model at this time
Oil pipe give pressure oil pressure, pressure oil transmits pressure and gives retaining ring, and retaining ring up moves, and forces plugging leather cup to encircle
Rise, such as run into that inner-walls of duct is uneven, and plugging leather cup shirt rim is swollen outward, so that plugging leather cup shirt rim is firmly fitted in pipe
On road inner wall, sealing operation is completed.
The beneficial effects of the utility model are that the utility model effectively overcomes tradition using Inner expanding plug block heads
Plug block head because closure helix tube and the rough smooth pressure pipeline of inner wall and caused by leak, improve the safety of operation
Property, convenience and the feature of environmental protection.
Brief description of the drawings
Fig. 1 is a kind of internal-expansion type plugging head structure schematic diagram of the utility model embodiment.
Embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Referring to Fig. 1, showing internal-expansion type block head 100, containing fixed mechanism 30, bracket institution 20, oil pipe 10 and envelope is oriented to
Stifled mechanism 40, fixed mechanism 30 contain connecting bracket 2 and connector containing fixed frame 1, the edge of a knife 8 and top fixing bolt 9, bracket institution 20
12；Plugging mechanism 40 is oriented to containing plugging leather cup 3, retaining ring 4, pressure oil 5, leading truck, oil connection 7 and directive wheel 11a and is led
To wheel 11b.Bracket institution 20 connects the fixed mechanism 30 by connector 12, is oriented to plugging mechanism 40 and is installed on bracket institution
20 one end, the connection of oil pipe 10 are oriented to the oil connection 7 on plugging mechanism 40；1 lower end of fixed frame is welded with the edge of a knife 8, fixed frame 1
Bottom righthand side is connected with top fixing bolt 9；The installation of plugging leather cup 3 is oriented to the round edge of plugging mechanism 40, and retaining ring 4 is placed in the closure
Among the inner side of leather cup 4, pressure oil 5 is installed on 4 lower end of retaining ring, and oil connection 7 connects the pressure oil 5, and directive wheel 11a, lead
Two vertex positions of the leading truck 6 are separately mounted to wheel 11b, the installation of leading truck 6 is oriented to the side of plugging mechanism 40.
Bracket institution 20 is rotated centered on connector 12, and rotating range is down toward the position of the top fixing bolt 9, inverse time
Clock is rotated to the position parallel with 30 vertical edge of fixed mechanism of plugging mechanism 40 is oriented to, its effect is in internal-expansion type block head 100
When down moving, the position of bracket institution 20 is close to 100 position of top fixing bolt of fixed mechanism 30.When internal-expansion type block head
After 100 enter pipeline, the rotation of 20 inverse clock of bracket institution, makes guiding plugging mechanism 40 block pipeline.
Further, top fixing bolt 9 is placed on the side of fixed mechanism 30, the reference azimuth of fixing bracket mechanism 20,
When needing the overall reference azimuth of vernier supporting structure 20, top fixing bolt 9 need to be only screwed.
Further, plugging leather cup 3, which is installed on, is oriented on the round edge of plugging mechanism 40, uses abrasive rubber material, closure
Leather cup 3, which touch, treats blocking pipe inner wall, it is sealed.
Further, 4 seal pressure oil 5 of retaining ring, retaining ring 4 for one activity endless means component, when retaining ring 4 by
During the pressure given to pressure oil 5, retaining ring 4 arches upward, and plugging leather cup 3 is bonded blocking pipe inner wall more firm.
Further, pressure oil 5 is in state to be stressed, oil pipe 10 by 7 connected pipes 10 of oil connection, pressure oil
Connect external hydraulic device（It is not shown）, 5 final stress of pressure oil.
Further, the installation of leading truck 6 is oriented to the side of plugging mechanism 40, shows triangle, the effect of this shape is more
Enter in pipeline well.
Further, directive wheel 11a and directive wheel 11b be installed on leading truck 6 two vertex positions, directive wheel 11a and
Directive wheel 11b is the rubber or rigid plastics wheel of moving rotary, and the effect of directive wheel is to avoid guiding plugging mechanism 40 from touching
Treat the generation direct friction of block-up position.
Further, the edge of a knife 8 is the sharp sawtooth of metal for being welded on the lower section of fixed mechanism 30, when the effect of the edge of a knife is lower stifled
Cutting pipes.
Specific implementation step is：Internal-expansion type plug block head 100 is entered in pipeline in an initial condition, bracket institution 20
Close to 9 side of top fixing bolt of fixed mechanism 30, rotating support mechanism 20, make it rotate counterclockwise at this time, because being oriented to closure
Mechanism 40 is installed on 20 one end of bracket institution, is oriented to plugging mechanism 40 and follows bracket institution 20 to rotate, during rotating, such as
When directive wheel 11a and directive wheel 11b touch external component, because directive wheel rolls, therefore can be to avoid guiding plugging mechanism 40
Other external components of scratch, reach when in blocking pipe, plugging leather cup 3 is bonded inner-walls of duct, such as when being oriented to plugging mechanism 40
Run into inner-walls of duct and get rusty uneven, plugging leather cup 3 can not be bonded inner-walls of duct completely, therefore can produce the situation of gas leakage.
External hydraulic device at this time（It is not shown）Give pressure oil 5 pressure by oil pipe 10, pressure oil 5 transmits pressure and gives retaining ring 4,
Retaining ring 4 up moves, and forces plugging leather cup 3 to arch upward, and such as runs into that inner-walls of duct is uneven, and 3 shirt rim of plugging leather cup is swollen outward,
So that plugging leather cup shirt rim is firmly fitted on inner-walls of duct, sealing operation is completed.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
New interest field, therefore the equivalent variations made according to the utility model claims, still belong to what the utility model was covered
Scope.
