Detailed description of the invention
As Figure 1-3, steel concrete pile crown shearing-crushing device, this device comprises pile crown scissors broken arm 1, shear arm fixed support large arm 2, support works disk 3, dynamicliquid pressure jack 4, mechanical fastener 5, dynamicliquid pressure jack fixed leg 6, shear arm top set bolt 7, shear arm fixed support bolt 8.
The broken arm 1 of pile crown scissors is stiffening member, its number four; The broken arm 1 of each pile crown scissors is provided with the through hole installing shear arm top set bolt 7, shear arm fixed support bolt 8; The through hole of described installation shear arm top set bolt 7 is arranged on the top of the broken arm 1 of pile crown scissors, and the through hole installing shear arm fixed support bolt 8 is arranged on the below of the through hole installing shear arm top set bolt 7.
The broken arm 1 of pile crown scissors is connected by shear arm fixed support large arm 2 with support works disk 3; Described shear arm fixed support large arm 2 is connected with support works disk 3 by welding; The broken arm 1 of pile crown scissors is fixed by shear arm fixed support bolt 8 with shear arm fixed support large arm 2.
Dynamicliquid pressure jack 4 one end is connected with dynamicliquid pressure jack fixed leg 6, and the other end is connected with the shear arm top set bolt 7 of the broken arm 1 of pile crown scissors; Dynamicliquid pressure jack fixed leg 6 is fixed on support works disk 3; Mechanical fastener 5 is arranged on the center of support works disk 3, and mechanical fastener 5 is connected with big arm of digger top.
Broken 1 point, the arm of described four pile crown scissors is located on support works disk 3, and is symmetrically evenly arranged.
The hydraulic system of described excavator is connected with dynamicliquid pressure jack 4, for it provides power.
The course of action of this device is as follows, this device mechanical fastener 5 is fixed on big arm of digger top, utilize the hydraulic power system on excavator, utilize dynamicliquid pressure jack fixed leg 6 to be fixed on dynamicliquid pressure jack 4 transmitting power on support works disk 3 by hydraulic oil pipe to one end, make dynamicliquid pressure jack 4 produce telescopic moving.By the dynamicliquid pressure jack set bolt 7 on broken arm 1 top of pile crown scissors, the broken arm 1 of pile crown scissors is driven to move.Because the broken arm 1 of pile crown scissors utilizes shear arm fixed support bolt 8, be fixed in shear arm fixed support large arm 2, shear arm fixed support large arm 2 is connected with support works disk 3 by welding, just defines a support system to the broken arm 1 of pile crown scissors like this by shear arm fixed support bolt 8, shear arm fixed support large arm 2 and support works disk 3.By lever principle, under the drive of dynamicliquid pressure jack 4, broken arm 1 bottom of pile crown scissors just creates shear effect, reaches the object that machine carries out steel concrete pile crown shearing-crushing.
Steel concrete pile crown shearing-crushing device is furnished with altogether four dynamicliquid pressure jack 4 and four broken arms 1 of pile crown scissors, so just on two orthogonal, produces shear effect.Shear and carry out from top to bottom, first be that dynamicliquid pressure jack 4 shrinks, the broken arm 1 of pile crown scissors is driven to open, then by big arm of digger, steel concrete pile crown shearing-crushing device is placed in reinforced concrete pile crown portion, now dynamicliquid pressure jack 4 stretches out, the broken arm 1 of pile crown scissors is driven to move to steel concrete pile crown center, until steel concrete pile crown is broken.Iterative cycles, completes whole steel concrete pile crown breaker and does, and reaches the machinery research and development effect of anticipation.
