Shown in be nine hydraulic broken pile units.The hydraulic cylinder includes cylinder barrel 2, the piston rod being arranged in cylinder barrel 23, is arranged in cylinder
The end cap 7 of 2 front ends of cylinder, cylinder barrel 2 are equipped with inlet 1.The support shoe apparatus includes supporting boot bar 5, supporting boot 9, supporting boot
Bar 5 includes coaxially connected columned first bar portion 51 and columned second bar portion 52, and the diameter of the first bar portion 51 is greater than
The internal diameter of the diameter of second bar portion 52, the cylinder barrel 2 of the diameter cylinder of the first bar portion 51 is suitable.The middle part of the supporting boot bar 5
With axially extending bore that is axial through the first bar portion 51 and the second bar portion 52 and being passed through for the piston rod of hydraulic cylinder 3.The branch
The middle part for supportting boots 9 has through-hole, and supporting boot 9 is threadedly attached in the front end of the second bar portion 52 of supporting boot bar 5, supporting boot
9 are coaxially disposed with hydraulic cylinder.In the present embodiment, the front end of supporting boot 9 is circular shape, and the front end face of supporting boot 9 is platform
Stepped structure.First bar portion 51 of the supporting boot bar 5 is located in the cylinder barrel 2 of hydraulic cylinder and is sleeved on the piston rod 3 of hydraulic cylinder
On, piston rod spring 4, piston rod are provided between the lower end of the first bar portion 51 of the piston rod 3 and supporting boot bar 5 of hydraulic cylinder
Spring 4 is sleeved on piston rod 3.The hydraulic cylinder connecting bracket 8 be bolted to connection hydraulic cylinder end cap 7 it is outer
Side, the middle part of hydraulic cylinder connecting bracket 8 have the through-hole that the second bar portion 52 for supporting boot bar 5 passes through.Supporting boot bar 5 with
The supporting boot bar spring 6 being provided between hydraulic cylinder connecting bracket 8 in the second bar portion 52 for being sleeved on supporting boot bar 5.It is described broken
Stake bore bit 10 is detachably connected to the front end of the piston rod 3 of hydraulic cylinder.The spring force value of the supporting boot bar spring 6 is set as
Less than the spring force value of piston rod spring 4.Each hydraulic broken pile unit utilizes mounting pin 11 successively by its hydraulic cylinder connecting bracket 8
It is connected with each other and forms a circular configuration, the axis of all hydraulic cylinders is in the front end of approximately the same plane and each hydraulic cylinder
Circle center distance away from circular configuration is equal.To be each provided with connection at left and right sides of each hydraulic cylinder connecting bracket 8 convenient for connection
Pin hole is arranged on connecting plate in plate, and the connection between hydraulic broken pile unit is realized in the pin hole cooperation in mounting pin 11 and connecting plate.For
Guarantee each hydraulic cylinder synchronous movement, the oil circuit of the hydraulic cylinder of each hydraulic broken pile unit is using series connection.The oil circuit of hydraulic cylinder with
The hydraulic power unit of configuration connects.
When utility model works, hydraulic oil is injected the cylinder barrel 2 of hydraulic cylinder by hydraulic power unit by the oil inlet 1 of hydraulic cylinder
Interior, hydraulic oil pushes piston rod 3 to move, and the power being subject to is transmitted to piston rod spring 4 by piston rod 3, and piston rod spring 4 passes power
Supporting boot bar 5 is passed, supporting boot bar 5 transmits the force to supporting boot spring 6 again.Since the spring force value of supporting boot spring 6 is than living

The supporting boot 9 of 5 front end of supporting boot bar can be contacted with concrete-pile when boots bar 5 stretches out to a certain extent.With hydraulic oil injection rate
Increase, piston rod spring 4 starts to compress when supporting boot spring 6 compresses to a certain extent, and broken pile bore bit 10 stretches out supporting boot 9 at this time
Start to contact concrete-pile, carries out pile crown and abolish work.After pile crown abolishes completion, broken pile machine commutation valve events make hydraulic cylinder
The work of the connection of the fuel tank of oil inlet 1 and hydraulic power unit, piston rod 3 and supporting boot bar 5 in piston rod spring 4 and supporting boot spring 6
It forced back towards original position under, completes broken pile work.
In the broken pile machine course of work, with the movement of piston rod 3, supporting boot 9 can be more next to the extruding force of concrete-pile
It is bigger, if broken pile machine has a certain degree with pile body at this time, the interaction force of supporting boot 9 and concrete-pile can make broken pile machine with
Pile body is adjusted to plumbness, ensures that the broken pile bore bit 10 of each hydraulic cylinder of broken pile machine is on the same working face in this way, protects
The work quality of broken pile base work original state is demonstrate,proved.
Broken pile bore bit 10 stretch out supporting boot 9 start contact concrete-pile carry out pile crown abolish work when, broken pile machine passes through
The high terrace of supporting boot 9 is contacted and is tightened together with the part that concrete-pile does not need to abolish, and avoids broken pile pricker in this way
First 10 when carrying out broken pile work caused broken pile machine entirety jumping phenomena, ensure that face of entirely abolishing after the completion of broken pile machine broken pile
Flatness, improve broken pile work quality.
Other parts in the present embodiment are the prior art, and details are not described herein.
