The leveling block 522 is provided with a sliding groove 5221 towards one side of the ball groove 5211, the sliding block 525 is slidably arranged in the sliding groove 5221, the bottom wall of the sliding groove 5221 is provided with a guide block 526, and the adjusting ball 524 abuts against the sliding block 525. The bottom wall of the sliding groove 5221 is provided with a guide block 526, one end of the guide block 526, which is away from the bottom wall of the sliding groove 5221, is provided with a guide inclined surface 5261, a ball 527 is arranged between the guide inclined surface 5261 and the sliding block 525, and the ball 527 is simultaneously abutted against the guide inclined surface 5261 and the sliding block 525. An adjusting screw 528 is screwed on the side wall of the adjusting block, and one end of the adjusting screw 528 extends into the sliding groove 5221 and abuts against the ball 527.

Referring to fig. 2 and 4, in the process of detaching the hanging cover 8, the piston rod of the jack 2 approaches the leveling plate 51 and abuts against the leveling plate 51 to push the leveling plate 51 to approach the support beam 11. At this time, the leveling plate 51 stretches the first tension spring 53, and the first tension spring 53 generates a reverse acting force on the leveling plate 51, so that the leveling plate 51 is pulled to abut against the end surface of the piston rod of the jack 2, and the leveling plate 51 is made to abut against the end surface of the piston rod. Until the leveling plate 51 abuts against the leveling block 522, the operator rotates the adjustment screw 528, so that the adjustment screw 528 pushes the balls 527 to roll on the guide slopes 5261. Meanwhile, the ball 527 pushes the sliding block 525 to slide in the sliding groove 5221, the gap between the adjusting block and the fixing block 521 is adjusted through the adjusting ball 524, the end face of the leveling block 522 departing from the fixing block 521 completely butts against the wall surface of the leveling plate 51, so that the jack 2 can better apply the thrust to the supporting beam 11, the supporting beam 11 can be more stably thrust, the supporting beam 11 is uniformly stressed, and the lifting smoothness of the jack 2 is improved.

The implementation principle of the flange splitting device utilizing the bolt holes to generate large thrust is as follows: in the process of dismounting the hanging cover 8, an operator firstly inserts the base plate 16 into the gap between the hanging cover 8 and the top flange 9, so that the base plate 16 shields one of the bolt holes on the top flange 9. The operator then passes the support pole 12 through the bolt hole in the cap 8 and against the backing plate 16 so that the backing plate 16 supports the support pole 12. Meanwhile, the operator inserts the support cylinder 61 into the bolt hole to fix the support rod 12, so as to increase the stability of the support rod 12. The operator then places the jack 2 on the positioning plate 71 and rotates the abutting block 74, so that the abutting block 74 pushes the pressing plate 72, and the pressing plate 72 pushes the abutting plate 73 to abut on the jack 2, so as to achieve the effect of fixing the jack 2.

The operator inserts one of the tie rods 13 into the bolt hole of the drop cap 8 adjacent to the support rod 12 and inserts the other tie rod 13 into the other bolt hole adjacent to the support rod 12 so that the tie rod 13 pushes the stopper 14 into the bolt hole of the top flange 9. The operator then inserts the pin plate 15 into the gap between the top flange 9 and the flap 8, so that the tie rod 13 engages in the recess 151. Then the operator starts the jack 2, so that the piston rod of the jack 2 pushes the leveling plate 51 to abut against the leveling block 522, and at the moment, the operator rotates the adjusting bolt, so that the leveling block 522 is tightly attached to the leveling plate 51. Finally, an operator sets four splitting supports 1 and jacks 2 along the circumferential direction of the hanging cover 8 and simultaneously starts the four jacks 2, so that the jacks 2 push the supporting beam 11 to move towards one side far away from the hanging cover 8, the supporting beam 11 drives the pull rod 13 to move, the pull rod 13 drives the pin plate 15 through the stop block 14 to abut against the hanging cover 8, and the pin plate 15 generates strong thrust to the hanging cover 8 so as to achieve the effect of removing the hanging cover 8 from the top flange 9.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
