The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises cylinder 5, and cylinder 5 surface uniforms are provided with a plurality of voussoirs 4, and each voussoir 4 is along cylinder 5 circle distribution.Described voussoir 4 surfaces are along cylinder 5 axis directions inclined-plane from high to low.The angle on the inclined-plane of described voussoir 4 and cylinder 5 surfaces is 10 ~ 20 °.
The utility model also comprises and voussoir 4 a plurality of Slave Blocks 2 one to one, and Slave Block 2 lower surfaces coordinate and contact with voussoir 4 upper surfaces.As shown in Figure 4, described Slave Block 2 lower surfaces are along cylinder 4 axis directions inclined-plane from low to high.
Each Slave Block 2 comprises at least two equal and opposite in directions, the follower plate 14 evenly arranging, and between follower plate 14, abutting end is provided with adjusting play 16.When follower plate 14 outwards struts, by adjusting play 16, make follower plate 14 when outwards strutting, do not collide with each other.In embodiment as shown in Figure 3, the follower plate 14 that each Slave Block 2 comprises is three.
The follower plate 14 of each same position of a plurality of Slave Blocks 2 links into an integrated entity by least one pull bar 1, and the two ends of each pull bar 1 are common respectively connects an end plate 6, and by the nut check connecting on pull bar 1.
On described follower plate 14 and pull bar 1 junction is provided with oblong adjustment hole 13, and adjustment hole 13 is convenient to follower plate 14 and is outwards strutted.
On described pull bar 1, between every two Slave Blocks 2, be provided with a distance sink tube 3, by distance sink tube 3, separate Slave Block 2 and position, prevent Slave Block 2 deviation positions.
The interior center of cylinder 5 is provided with core pipe 11, between cylinder 5 and core pipe 11, by a plurality of gussets 12, connects.Described a plurality of gusset 12 is uniformly distributed.
