In embodiment, the outer diameter of the bearing disc 11 is consistent with the internal diameter of outer barrel 1, can the movement of axial dynamic sealing be set to outer barrel
In 1, for example, being equipped with multiple convex blocks on the outer wall of bearing disc 11, there are multiple axial grooves, those are convex on the inner wall of outer barrel 1
Block is embedded in those axial grooves and can slide in axial groove, and certainly, the utility model is not limited to this structure, as long as can guarantee
Bearing disc 11 can be relative to 1 axial seal of outer barrel mobile.
Balance weight 12 is made of metal material, and can be disc, can also be to be cube shaped, and outer diameter is less than bearing disc
11 outer diameter.The balance weight 12 can be resiliently connected to the lower end of bearing disc 11, in the present embodiment, in balance weight 12 and pressure-bearing
Compressed spring 17 is connected between disk 11.The compressed spring 17 is metal material, is respectively fixedly connected under bearing disc 11
The center position of end face and the upper surface of balance weight 12, when the compression of bearing disc 11 moves down, compressed spring 17 is compressed
It then moves down, after the discharge degree born on bearing disc 11, the compressed spring 17 is extensive under the action of elastic potential energy
It restores shape and prolongs the axis of outer barrel 1 and move up.
Further, in the present invention, as shown in Figures 2 and 3, opened at the lower end surface centre of balance weight 12
Equipped with radial slot 121, top pin shaft 122 is connected at the middle part of radial slot 121.
It is connected with being able to rotate between the first vertical bar 21 and first level bar 22 of first connecting rod mechanism 2 by pin shaft 23,
The first level bar 22 can be rotated around the pin shaft 23 between the first vertical bar 21 to be arranged；The upper end of first vertical bar 21 passes through
Top pin shaft 122 is movably connected in the radial slot 121 of 12 lower end surface of balance weight, which can be around top pin shaft
The 122 radially extending direction rotations of slot 121 in radial slot 121, are rotatably connected on balance weight 12 to be able to achieve
Purpose；The end of the first level bar 22 is rotatably connected on the first ring block 13 by pin shaft 24.
In the present embodiment, please refer to shown in Fig. 4, horizontal middle spindle is equipped at the middle part of the first vertical bar 21
25, the both ends of the horizontal middle spindle 25 are respectively fixedly connected on the barrel of outer barrel 1, and the horizontal middle spindle 25 and first is vertically
Bar 21 is vertically arranged.It is fixed on outer barrel 1 at the shaft core position of first vertical bar 21 by horizontal middle spindle 25, this first
Vertical bar 21 can be rotated around horizontal middle spindle 25, which is circular metal rod piece.
It is connected with being able to rotate between the second vertical bar 31 and the second horizon bar 32 of second connecting rod mechanism 3 by pin shaft 33,
Second horizon bar 32 can be rotated around the pin shaft 33 between the second vertical bar 31 to be arranged；The upper end of second vertical bar 31 passes through
Top pin shaft 122 is movably connected in the radial slot 121 of 12 lower end surface of balance weight, which can be around top pin shaft
The 122 radially extending direction rotations of slot 121 in radial slot 121, are rotatably connected on balance weight 12 to be able to achieve
Purpose；The end of second horizon bar 32 is rotatably connected on the second ring block 14 by pin shaft 34.
In the present invention, from the point of view of at the top of the interior starting tool, the first connecting rod mechanism 2 and second connecting rod mechanism
3 are overlapped with the radial slot 121 on balance weight 12.
The course of work of the interior starting tool of the conduit bearing capacity stiffening device is as follows:
When constantly injecting seawater or other fluids in outer barrel 1, the work of bearing disc 11 in outer barrel 1 in head of liquid
With downlink and compressed spring 17 is compressed, until compressed spring 17 is with the downlink together of balance weight 12, the first vertical bar 21 at this time
It is rotated clockwise around horizontal middle spindle 25, the upper end of the upper end of the first vertical bar 21 and the second vertical bar 31 is with balance weight 12 1
Same downlink, first level bar 22 and the first ring block 13 are mobile to the side of outer barrel 1 together with the lower end of the first vertical bar 21
Until the first ring block 13 stretches out outer barrel 1 and is connected in the keyway 101 reserved on the annulus 10 of conduit bearing capacity stiffening device,
As shown in figure 5, the second horizon bar 32 and the second ring block 14 are as the lower end of the second vertical bar 31 is together to the other side of outer barrel 1
Movement is until the second ring block 14 stretches out outer barrel 1 and is connected to the keyway reserved on the annulus 10 of conduit bearing capacity stiffening device
In 101.After the second ring block 14 and the first ring block 13 are clamped in place, about 30 degree of the interior starting tool is rotated, conduit is held at this time
