Embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Referring to Fig. 1, show that opposite opened blocks expansion cylinder 200, by two symmetrical expansion mechanism 1a and expansion mechanism 1b
Composition, each expansion mechanism is containing expansion wedge 2, center bolt 3, positioning plate 4, connection on upper mounted plate 1, bottom plate 6, band outer cone
5 and half formula of wedge band inner cone expansion cylinder 7 is expanded under frame 8, band outer cone；Center bolt 3 is located at two symmetrical semicircle expansion mechanisms
Centre, connects the center bolt 3, upper mounted plate 1, which is arranged on band outer cone, expands 2 upper end of wedge, outside band with expansion wedge 2 on outer cone
The lower expansion wedge 5 of cone connects the center bolt 3, and bottom plate 6, which is arranged under band outer cone, to be expanded below wedge, positioning plate 4 positioned at pair
Open type blocks the centre of expansion cylinder, and positioning plate 4 is fixed on center bolt 3, expanded under band outer cone wedge 5 with expanding wedge on outer cone
2 using 4 center line of positioning plate as symmetrical axial symmetry, and half formula band inner cone expansion cylinder 8 is fixedly connected on frame 8, and link 8 is positioned at described
With wedge 2 and the side with expansion wedge 5 on outer cone is expanded under outer cone, bottom plate 6, upper mounted plate 1 connect the link.
Further, i.e., two semicircle expansion mechanism 1a as the structure of 1b, therefore in the present embodiment, only describe it
In an expansion mechanism structure.
Further, cylinder cambered surface of half formula with inner cone expansion cylinder 7 is semicircle, during implementing to block, blocks pipe
Road one is to two and half formulas block two of pipeline with inner cone expansion cylinder.
Further, the male cone (strobilus masculinus) and half formula band inner cone expansion cylinder with wedge 2 is expanded on outer cone and with being expanded under outer cone on wedge 5
The angle that body 7 is formed is 7 °, this angle is beneficial to expand expansion 5 transmitting thrust of wedge under wedge 2 and the band outer cone on outer cone and gives half formula
Band inner cone expansion cylinder 7.
Further, wedge 2 is expanded on band outer cone and is connected center bolt respectively with expansion wedge 5 under outer cone, center bolt 3 revolves
Turn to drive and wedge 2 is expanded on band outer cone with 5 movement symmetrical above and below of wedge is expanded under outer cone, i.e., movement close to each other or being located remotely from each other shifting
It is dynamic, when close to each other mobile, that is, half formula is given with the outside thrust of inner cone expansion cylinder 7, this is closure operation.
Further, positioning plate 4 is fixed on center bolt 3, and it is overall that positioning plate 4 fixes opposite opened closure expansion cylinder 200
The position of vertical direction, i.e. positioning plate 4 determine integral position.
Further, bottom plate 6 is fixed on lower expansion wedge 5 in the following, 6 both ends of bottom plate carry T-slot, with being connected
8 fiting constraint of frame, half formula band inner cone expansion cylinder 7.
Further, upper mounted plate 1 is fixed on expansion wedge 2 in the following, 1 both ends of bottom plate carry T-slot, with being connected
8 fiting constraint of frame, half formula band inner cone expansion cylinder 7.
Specifically implementation steps are：Opposite opened closure expansion cylinder 200, which is in, to be treated in blocking pipe, pivot spiral shell counterclockwise
Bar 3, moves down with expansion wedge 2 on outer cone, and expansion wedge 5 up moves under band outer cone, in moving process, 1 phase of fixed frame
It should move down, fixed frame 6 accordingly moves down half formula of constraint with inner cone expansion cylinder 7, is press-connected frame by the conical surface at this time
8, so force half formula band inner cone expansion cylinder 7 move right, complete twin conduit one to closure.
Expansion cylinder 200 is blocked by the identical and symmetrical semicircle expansion mechanism group of two structures accordingly, due to open type
Into, pipeline two is blocked respectively, therefore a sealing space can be formed among open type closure expansion cylinder 200, if this
Sealing space sealing without leakage, you can more easily judge that pipe plugging will not be revealed, and judge sealing space and do not reveal
Method need to only pressurize detection.
Fig. 2 is opposite opened closure 200 horizontal sectional view of expansion cylinder of the utility model embodiment, mainly lists opposite opened envelope
The shell portion of stifled expansion cylinder 100, containing half formula band inner cone expansion cylinder 7a, half formula band inner cone expansion cylinder 7b, 3 and of center bolt
Fixed frame 8, in implementing to block operation, under the driving of center bolt 3, half formula band inner cone expansion cylinder 7a and half formula band inner cone
Cylinder 7b is expanded to external expansion blocking pipe.
Fig. 3 be the utility model embodiment 2 be in pipeline in opposite opened closure expansion cylinder structure diagram, this implementation
Example 2 and Fig. 1 embodiments 1 are essentially identical, are a difference in that and place opposite opened closure expansion cylinder in the duct, split easy to show
Formula blocks the embodiment of expansion cylinder.Part 11b containing sealing pipeline, replacement pipeline 11a and the pipe plugging of difference are fixed
Frame 12a, open type closure expansion cylinder contain two expansion mechanisms, each expansion mechanism 1a containing upper mounted plate, bottom plate 6a, band outer cone
Wedge 5a and half formula band inner cone expansion cylinder are expanded under upper expansion wedge 2a, center bolt 3a, positioning plate 4a, link 8a, band outer cone
7b。
The closure step and embodiment in Fig. 11 of specific implementation are essentially identical, pivot screw rod 3a counterclockwise, band outer cone
Upper expansion wedge 2a moves down, and expansion wedge 5a is up moved under band outer cone, under the pressure of expansion wedge, forces half formula band inner cone swollen
Swollen cylinder 7b blocks sealing pipeline 11b toward moving right, and correspondingly, replaces pipeline 11a and is also blocked up by half formula band inner cone expansion cylinder
Firmly, because two is all blocked by sealing, sealing space is formed between two and half formulas band inner cone expansion cylinder, is sealed by detecting
Whether whether the tightness in space block close judging two or reveal.
The main efficacy results of opposite opened closure expansion cylinder are：1st, closure can be made tighter pressurization in cylinder in closure,
And easy to detect closure tightness with pressure gauge；Plugging effect is improved, greatly increases the security of construction operation;2nd, expansion cylinder cylinder
Body can achieve the purpose that not open that balance hole is diffused in replacement pipeline section one end perforate.
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.
