It can be convenient replacement pull rod 3.For example, for the ring flange and blind flange of different model, the diameter of screw hole is not also identical.It is above-mentioned
Setting can be convenient by replacing pull rod 3, to correspond to the connecting hole 31 of different-diameter.
Specifically, pull rod 3 can be sheathed on the outside of crossbeam 2, and pull rod 3 is connect with crossbeam 2 by connector 6.Connection
Part 6 can be fastening screw.The fixation hole 221 for wearing connector 6 is provided on cross bar 22.Pull rod 3 is far from connecting hole 31
End be provided with the through-hole for wearing connector 6.
Since the ring flange of different model and the sum of the thickness of blind flange is not identical, so between two pull rods 3
Required distance is not identical.Therefore, the connection relationship between pull rod 3 and crossbeam 2 can be set are as follows: along the extending direction of crossbeam 2,
The both ends of crossbeam 2 are respectively arranged with multiple fixation holes 221；Connector 6 is set as connecting rod, and connecting rod correspondence is arranged in fixation hole
In 221, to adjust the distance between two pull rods 3, as shown in Figure 5.Above-mentioned setting, not only can be by adjusting two pull rods 3
The distance between, so that the flange and ring flange of different model can be placed between two pull rods 3.Meanwhile ring flange and flange
When the thickness of lid is not identical, when carrying out blind flange dismounting, in addition to adjustable two pull rods 3 arrive blind flange and flange respectively
The distance between outside can also pass through so that apical grafting head 121 is aligned with the joint face of ring flange and blind flange and adjust two
Pull rod 3 arrive the distance between movable mandril 12 respectively with correspond to different-thickness ring flange, blind flange is, it can be achieved that different-thickness
Blind flange removes work.
The cross section of above-mentioned crossbeam 2 can be rectangle, so that the connection between crossbeam 2 and pull rod 3 fastens.Pull rod 3 and crossbeam 2
Connecting pin cross section can be greater than pull rod 3 far from the cross section at crossbeam 2 so that pull rod 3 is connected firmly at crossbeam 2.
The thickness range of above-mentioned connection ring 21 can be with are as follows: 12-18mm.For example, connection ring 21 with a thickness of 15mm, it is above-mentioned
Setting fastens connection ring 21 more.
Further, blind flange extracting tool provided by the utility model can also include screw rod and multiple nuts；Screw rod
For being arranged in the screw hole of connecting hole 31 and ring flange and blind flange.
When using blind flange extracting tool provided by the utility model, crossbeam 2 is mounted on 11 outside of oil cylinder ontology, it will be horizontal
Beam 2 is up screwed in from 1 body bottom portion of hydraulic cylinder, and screw-in depth is adjustable with certain nargin.Secondly, 2 liang of crossbeam of installation
The pull rod 3 of side, while the blind flange extracting tool for using utility model to provide being mounted on to a circle in 12 directions of ring flange
Long screw rod is sequentially passed through one of 3 bottom connecting hole 31 of pull rod, passes through 12 directions on ring flange and blind flange by Kong Shang
A screw hole (fastening screw of ring flange has been removed before this), pass through another 3 bottom connecting hole 31 of lateral bracing strut after, pass through spiral shell
Mother's fastening.1 drive activity mandril 12 of hydraulic cylinder steadily moves downward, and flat apical grafting head 121 is from ring flange and blind flange
Middle position is horizontally inserted into, and the sealing surface of ring flange and blind flange is constantly squeezed under the action of hydraulic cylinder 1, finally enables flange
Lid is detached from the fixation of sealed silicone, easily removes blind flange.Compared with existing GIS blind flange dismantles mode, the utility model is mentioned
The blind flange extracting tool structure of confession is simple, easy to use, reliable operation.Pass through the behaviour of 1 push activity mandril 12 of hydraulic cylinder
Make mode and the design of 121 flat structure of apical grafting head, the guaranteed ring flange disassembly process stress of energy is steadily balanced, it avoids hitting,
