The utility model adopts the technical scheme as follows: a fan-shaped section overhauling cushion block is connected between a fan-shaped section guide post and an inner arc frame; the maintenance device comprises two arc-shaped maintenance blocks, and the two maintenance blocks form a cylinder shape after being fixedly connected relatively.
The two maintenance blocks are positioned between the inner arc frame 6 and the guide post 5 in a split manner and then fixedly connected together.
The height of the maintenance block is 5-10 mm lower than the stroke of the oil cylinder, and the diameters of the inner circle and the outer circle are consistent with those of the guide column.
The seam crossing of the maintenance blocks is respectively provided with a connecting block 2, and the two maintenance blocks 1 are fixed by the connecting blocks 2 and bolts.
And a gasket is arranged at the fixing position of the connecting block and the bolt.
Each segment of the sector section consists of 4 pull rods, and the guide post is sleeved outside the pull rods, and the lower part of the guide post is fixed with the outer arc frame; the inner arc frame moves up and down along the pull rod under the driving of the hydraulic cylinder.
The beneficial effects of the utility model are that, a fan-shaped section overhauls cushion has following advantage: the utility model discloses overhaul the cushion, fumble for and position, the continuous improvement of size through a large amount of practice operations, overhaul each cushion and install between guide post and inner arc frame, then the inner arc frame falls under the drive of pneumatic cylinder, this easy operation is high-efficient, if need overhaul the pneumatic cylinder, can close hydraulic control system this moment, disassemble the intermediate line, carry out the maintenance work of pneumatic cylinder can, need 4 people before work that can the operation, only need earlier two people can accomplish the online maintenance.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
The technical solution of the present invention will be described in further detail by the following embodiments.
The utility model provides a sector repair cushion block, as shown in figure 1-2, which is connected between a sector guide post 5 and an inner arc frame 6; the device comprises two arc-shaped maintenance blocks 1, wherein the two maintenance blocks 1 are oppositely and fixedly connected to form a cylinder shape; the maintenance cushion block is contacted with the guide post 5 and the inner arc frame 6 to play a bearing role.
The two maintenance blocks 1 are positioned between the inner arc frame 6 and the guide post 5 in a split manner and then fixedly connected together.
The height of the maintenance block 1 is 5-10 mm lower than the stroke of the oil cylinder, and the diameters of the inner circle and the outer circle are consistent with those of the guide column.
The seam crossing of the maintenance blocks 1 is respectively provided with a connecting block 2, and the two maintenance blocks 1 are fixed by the connecting blocks 2 and bolts 3.
The fixing position of the connecting block 2 and the bolt 3 is also provided with a gasket.
Each segment of the fan-shaped section consists of 4 pull rods 8, and the guide column 5 is sleeved outside the pull rods 8, and the lower part of the guide column is fixed with the outer arc frame; the inner arc frame 6 moves up and down along the pull rod 8 under the drive of the hydraulic cylinder 7.
