For screw and nut connection.
Further, hydraulically extensible oil is controlled flexible by hydraulic control system, drives two hydraulically extensible oil synchronization actions,
Generation makes the torque of casing short joint clockwise or counterclockwise.
Further, flange seat front and back is opened wide, and supporting rod passes through flange seat, when hydraulically extensible oil is stretched, folder
Bar is held not interfere with flange seat.
Further, wellhead assembly transfer when casing short joint rotates in order to prevent, center annular distribution is multiple on flange seat
Limit hole, limit bore dia is bigger than the screw rod of wellhead assembly lower part, nut, and screw rod, the nut of wellhead assembly lower part pass through limit
Hole, the rotation on the wellhead assembly top other than preventing decannulation from being shorted.
Use process is as follows:
When disassembly,
1. being placed on wellhead assembly on flange seat vertically with crane, flange seat, spiral shell are protruded into the one end for installing casing short joint
The limit hole of bar and nut insertion flange seat, the hanging ring of crane are not withdrawn, and are placed wellhead assembly stress and are toppled in unexpected situations；
2. casing short joint protrudes into casing slip center, casing slip is locked；
3. starting hydraulic control system, stretched or contracting hydraulically extensible oil, is unbuttoned according to the rotation direction of casing short joint；
4. loosening casing slip after casing short joint loosens, slinging wellhead assembly, unscrew casing with conventional tool such as spanner etc.
It is shorted.
When installation,
1. casing short joint pre-screwing is hung on flange seat, the limit hole of screw rod and nut insertion flange seat, crane
Hanging ring is not withdrawn, and is placed wellhead assembly stress and is toppled in unexpected situations；
2. casing short joint protrudes into casing slip center, casing slip is locked；
3. starting hydraulic control system, stretched or contracting hydraulically extensible oil, is tightened according to the rotation direction of casing short joint；
The utility model has the advantages that
1, it using hydraulic principle, can produce the torque of 20000 Ns of rice, detachably the more difficult casing short joint unscrewed, can also incite somebody to action
Casing short joint is tightened；
2, easy to operate, greatly reduce disassembly, artificial in installation process；
3, safety is higher.
Detailed description of the invention
Fig. 1 is the utility model structure and dismounting schematic diagram；
Fig. 2 is main structure top view when the utility model does not dismount.
In figure: 1 dismounting platform, 2 fixing seats, 3 flange seats, 4 casing short joints, 5 casing slips, 6 hydraulically extensible oils, 7 pins
Axis, 8 wellhead assemblies, 9 supporting rods, 10 hydraulic control systems.
