Description
Technical field
A kind of concrete-pile process equipment is the utility model is related to, more specifically, it relates to which a kind of pile crown abolishes device.
Background technology
In order to ensure that pile crown quality will typically be higher by stake top absolute altitude when pile foundation construction.
0.5m ~ 1m or so is superfilled part at general stake top;Superfilled part is mainly scum silica frost, laitance, and aggregate
It is few, insufficient strength.The problem of this is due to using that will necessarily be produced during construction process of bored concrete pile, because in concrete perfusion,
The impurity precipitated in the sediment and filling process at stake bottom in mud can form certain thickness in concrete surface, and we are commonly referred to as floating
Slurry.
So all 0.5m or so can be had more than cushion cap bottom surface absolute altitude during general pile foundation construction.
Such as bored concrete pile:It is necessary to which superfilled part is cut after concrete setting, broken pile head operation, Ran Houzhuan are carried out
Cage bar more than top mark is high(Reinforcing bar)Expose;Then, the reinforcing bar of pile foundation is stretched into cushion cap.
Now retrieve the Chinese patent document that a notification number is CN203514317U, its entitled hydraulic pressure broken pile machine, profit
Pile protection is set with multiple hydraulic cylinders for surrounding annular, drill rod is installed, drill rod is set in guide flange on the piston rod of hydraulic cylinder
It is interior;Under hydraulic power, all drill rods leave guide flange and ejected to the circle centre position of stake, by extruding stake, realize broken pile.
Due to carrying dregs during a large amount of broken piles on drill rod, after broken pile terminates, dregs is brought into guiding when drill rod bounces back
In flange, this causes the piston rod of hydraulic cylinder stretches out to be rubbed into during guide flange with dregs, the piston rod pole of hydraulic cylinder
Damage is easily reported because of excessive friction.
Utility model content
The purpose of this utility model is to provide a kind of pile crown and abolishes device, reaches and pressure head is carried out clearly using the brush body of rotation
Reason, reduce pressure head and enter inside casing.
Above-mentioned technical purpose of the present utility model technical scheme is that:
A kind of pile crown abolishes device, including piston rod, piston cylinder, casing and pressure head, and the port of export of casing is provided with to contradict and pressed

Move the sliding block in arc guide barrel, sliding block is towards piston cylinder movement to drive the track of brush body arcuately guide groove to rotate.
By using above-mentioned technical proposal, piston retraction, pressure head moves towards casing, and slider-actuated rotating cylinder rotates, brush body
When touching pressure head, cleaning when being surrounded to pressure head, and the brush body rotated has larger kinetic energy more easy to clean pressure head
On concrete slag.
Brush body is placed in casing end, it is therefore intended that concrete is cleared up in casing entrance, concrete slag is reduced and enters
To inside casing.
Preferably, the arc guide barrel includes helicla flute.
By using above-mentioned technical proposal, helicla flute rotation is more coherent, is advantageous to the smooth sliding of sliding block, rotating cylinder rotation
It is dynamic more smooth.
Preferably, the helicla flute is communicated with straight-line groove, and the straight-line groove is adjacent to the port of export of casing, the helicla flute neighbour
The other end of nearly casing.
By using above-mentioned technical proposal, sliding block is slid when straight-line groove, and rotating cylinder does not rotate;Sliding block is moved to casing and gone out
Mouth position, briquetting is outside casing, and now brush body and plunger rod contacts, in order to reduce abrasion of the brush body to piston rod, are brushed
Body does not rotate more excellent.
And when sliding block is moved to casing and deviates from exit end, brush body contacts with briquetting, and sliding block slides in helicla flute can
To cause the concrete slag of brush body high-efficiency rotating cleaning briquetting.
Preferably, the helicla flute includes interconnected narrow pitch groove and widely-pitched groove, the neighbouring shield of the widely-pitched groove
The port of export of cylinder, the other end of the narrow pitch groove adjacent to casing.
By using above-mentioned technical proposal, sliding block is moved to casing outlet port, and briquetting outside casing, is now brushed
Body and plunger rod contacts, in order to reduce abrasion of the brush body to piston rod, the brush body speed of rotation is smaller to be excellent, so when use wide spiral shell
Away from groove.
And when sliding block is moved to casing and deviates from exit end, brush body contacts with briquetting, the brush body speed of rotation comparatively fast to be excellent,
So when use narrow pitch groove.
Widely-pitched groove is helicla flute with narrow pitch groove, and the pitch of widely-pitched groove is more than the pitch of narrow pitch groove.
Preferably, the both ends of the casing are provided with the screening assembly of limitation rotating cylinder axial slip.By using above-mentioned skill
Art scheme, screening assembly cause rotating cylinder to be difficult to freely be axially disengaging casing.
Preferably, the screening assembly includes being screwed together in the positive stop of the casing port of export and is installed on the casing other end
Backstop.
By using above-mentioned technical proposal, positive stop screws togather removable, removes the casing of positive stop, departs from casing for rotating cylinder
Path is provided, is easy to the replacing of rotating cylinder.
Preferably, brush body annular is around pressure head.
It is more preferably excellent to the cleaning effect of pressure head around the brush body set by using above-mentioned technical proposal.
Preferably, brush body is heat-fused in rotating cylinder.
By using above-mentioned technical proposal, the stability of hot melt is higher, reduces the possibility that brush body freely departs from rotating cylinder,
Therefore brush body is bonded in piston rod and the possibility reduction of cylinder body is caught in piston rod movement.
Preferably, the one side that the sliding block contacts at arc guide barrel is convex surface.
By using above-mentioned technical proposal, convex surface surface smoothing is without knuckle, both when sliding block in arc guide barrel with sliding
Collision reduce, sliding block sliding it is more preferably smooth.
Preferably, sliding block includes the foundation for being fixed on piston rod, and foundation offers spherical cavity, freedom is placed with spherical cavity
The ball of rolling, convex surface are the spherical that ball is placed in spherical cavity.
It is rolling friction between ball and arc guide barrel by using above-mentioned technical proposal, sliding block is relative with arc guide barrel
Resistance is smaller caused by movement.
In summary, the utility model has the advantages that:With specialized rotation brush body Removal Technology, improve
The ability of maintenance of broken pile machine so that the overall service life of broken pile machine is lifted.
