Further, the supporting sleeve includes support plate and fixed frame, and sliding slot, the pulley are provided on the fixed frame
Inside sliding slot.
Further, the support plate is arc-shaped.
Further, with strut by being welded to connect, the intermediate sleeve is welded to connect the fixed ring with strut.
Further, the strut is hollow structure.
Advantageous effect is：The utility model substitutes mechanical mechanism using hydraulic mechanism, and when use puts the utility model
It sets inside pipe, pipe can be strutted by then starting hydraulic pump, eliminate manual operation, simpler using process, work
It is more efficient.

Specific implementation mode
Such as Fig. 1, hydraulic tube expander comprising 3, eight groups of hydraulic connecting rod mechanisms 2 of strut and four supporting sleeves 1, described in four
Supporting sleeve 1 is uniformly distributed around 3 side of strut and is provided with intermediate sleeve, Mei Gesuo in the middle part of the axial setting of strut 3, the strut
It states 1 lower section Jun Youliangzu hydraulic connecting rods mechanism 2 of supporting sleeve and Liang Zu hydraulic connecting rods mechanism 2 is symmetrical on the basis of intermediate sleeve, strut 3
Both ends are both provided with fixed ring 4, and with strut 3 by being welded to connect, intermediate sleeve is welded to connect fixed ring 4 with strut 3, and strut 3 is
Hollow structure, hollow structure save material, reduce cost of manufacture, each fixed ring 4 be respectively connected with four groups of hydraulic connection mechanisms and
The position that hydraulic pressure link mechanism 2 is arranged in two fixed rings 4 corresponds, every group of position corresponding Liang Zu hydraulic connecting rods mechanism
There are one supporting sleeves 1 for set outside 2 two output ends.
To provide power, every group of hydraulic connecting rod mechanism 2 includes follower lever 22 and hydraulic stem 23 for hydraulic connecting rod mechanism 2,
Hydraulic stem 23 connects external hydraulic pump by pipeline, and hydraulic stem 23 includes cylinder barrel 232 and telescopic rod 231,232 bottom of cylinder barrel with it is solid
Determine the articulated connection of ring 4,231 top of telescopic rod is articulated and connected with 22 shaft of follower lever, and 22 one end of follower lever hingedly connects with intermediate sleeve
It connects, the other end is provided with pulley 21.
Supporting sleeve 1 includes support plate 11 and fixed frame 12 to support pipe, supporting sleeve 1, and cunning is provided on fixed frame 12
Slot 13, pulley 21 are located inside sliding slot 13, and hydraulic stem 23 moves during propping up in sliding slot 13, and support plate 11 is circular arc
Shape, arc-shaped to be easier fitting tube blank inner wall, support plate 11 can make pipe uniform force when being softened, it is easier to paste
Close tube wall.
Lower mask body introduces the course of work of the utility model：By the utility model weaving inside pipe, start
Hydraulic pump, hydraulic pump drive the hydraulic stem 23 in every group of hydraulic connecting rod mechanism 2 that follower lever 22 is pushed to move, and follower lever 22 pushes branch
Support set 1 props up pipe, and during propping up, with the elongation of hydraulic stem 23, the angle between follower lever 22 and strut 3 constantly becomes
Greatly, supporting sleeve 1 is raised up to tube blank inner wall by follower lever 22, and during lifting, the pulley 21 on follower lever 22 is sliding on sliding slot 13
