The utility model belongs to pile foundation engineering boring bar tool, is related to a kind of boring drill bit of reducing.The device is transformed and optimized on the basis of conventional drill, the device includes drilling rod, movable blade row mounting seat, movable blade row, oil cylinder, cylinder installation seat, pin, augers, movable blade row are arranged in movable blade row mounting seat, tensed via oil cylinder, reducing effect can be reached by the size that control cylinder extension and contraction control activity blade row blade is opened.Compared with prior art, this drill bit has the reaming in drilling, is effectively reduced collapse hole probability, and can reduce drilling resistance, and drilling efficiency is high, reduces bit freezing risk, the advantages that ensureing drilling safe.

Description

A kind of boring drill bit device of reducing
Technical field
The utility model is related to a kind of boring drill bit device of reducing and construction method, be mainly used in municipal basis, Industry and the foundation stabilization in civil engineering construction, improve and prevent the fields such as cubic metre of earth displacement.
Background technology
Cast-in-situ bored pile is that stake holes is formed in foundation soil by means such as machine drilling, steel pipe soil compaction or manpower excavations, And steel reinforcement cage, concrete perfusion and the stake made are placed in it.
Coastal, soil property is softer area general at present all increases the bearing capacity of ground, resistance soil using cast-in-situ bored pile Square lateral pressure and prevent a cubic metre of earth displacement.Hole-drilling pile-filling machine is all to carry out bore operation using fixed drill bit at present, runs into needs During ream operation, the method that can only take more bit change, so not only complex operation, and time-consuming, effort, drilling efficiency are low; Furthermore it is big that resistance is crept into when being bored under fixed drill bit, easily causes collapse hole and pipe sticking.
Utility model content
The purpose of this utility model is exactly:Compared with prior art, this drill bit has the reaming in drilling, is effectively reduced Collapse hole probability, and can reduce drilling resistance, drilling efficiency is high, reduces bit freezing risk, the advantages that ensureing drilling safe.
The purpose of this utility model can be achieved through the following technical solutions:
Described drill bit device includes drilling rod, movable blade row mounting seat, movable blade row, oil cylinder, cylinder installation seat, pin, Augers, described drilling rod are fixed on the drilling rod of all-hydraulic pile-driving machine, and movable blade row mounting seat is welded on drilling rod, living Moving knife arranges one end in movable blade row mounting seat, and is fixed with pin, and cylinder installation seat is welded on drilling rod, oil cylinder one end Fixed on cylinder installation seat, and with pin, movable the blade row other end and the oil cylinder other end are installed together, and use pin It is fixed.
Described movable blade row, it can be become by the size that control cylinder extension and contraction control activity blade row blade is opened so as to reach Footpath effect.
Described oil cylinder carries stroke induction installation, can be with the signal of the size of Real-time Feedback bore diameter.
Described drill bit device is connected by bolt with all-hydraulic pile-driving machine, and oil cylinder oil pipe is connected to all-hydraulic drilled pile The hydraulic control system of machine, through the controller output order in driver's cabin can the blade row of control activity at any time opening diameter, should Drill bit device uses the oil cylinder with stroke induction installation, and the opening diameter for accurately controlling blade row is straight so as to ensure to drill Footpath.
The utility model has advantages below:
1) the utility model increase activity blade row and oil cylinder, allow bit diameter arbitrarily to change, so as to realize side The boring method of side reaming is crept into, drilling resistance can be reduced, drilling efficiency is high, reduces bit freezing risk;
2) the stroke induction installation in the utility model oil cylinder and main frame, hydraulic controller are connected to form one and controlled back Road, the size of bit diameter can be monitored in real time, so as in boring procedure with require change drilling size, this process without It need to can be achieved with bit change, save the engineering time, improve drilling efficiency;
Brief description of the drawings
Accompanying drawing 1:Structural representation of the present utility model
Accompanying drawing 2:Diameter changeable drill bit installation diagram
Embodiment
As shown in Fig. 2 described diameter changeable drill bit device is fixed by bolts to the drilling rod of all-hydraulic diving pile-driving machine, can Expansion bit device oil cylinder oil pipe is continuously connected to through the connection of drilling rod center on the hydraulic controller of all-hydraulic diving pile-driving machine, Hydraulic controller couples with the main frame in driver's cabin, thus constitutes a controllable loop.When operator was manipulated with quarter When the handle of degree is to specified location, controller, which receives, to be instructed and controls hydraulic system to make oil cylinder to oil cylinder output (or reduction) pressure The open angle of piston elongation (or shortening) control activity blade row, then adjusted by the feedback signal of oil cylinder up stroke induction installation Whole oil cylinder exports a steady pressure so as to reach predetermined diameter.
Using the construction method of above-mentioned diameter changeable drill bit device, can one-step pore-creating, expanded diameter is 700~1000mm.Tool Body includes following steps:
1) smooth construction site, full pattern is released according to construction drawing;
2) open channels are required according to construction drawing;
3) device resets, and the full liquid diving pressure pile-driving machine is moved into position to be onstructed, bit diameter is adjusted to just Beginning position;
4) open main frame to be monitored, pull the handle of disk with a scale to the size positions of drawing requirement, main frame is to hydraulic pressure Controller sends signal, and the elongation for the signal control cylinder that hydraulic controller is exported by main frame makes bit diameter become big, simultaneously Stroke induction installation on oil cylinder, which is sent, feeds back signal to the pressure that hydraulic controller stablizes its output, allows bit diameter always Keep the drilling size needed for drawing;
5) Power Component is started, Power Component driving drilling rod rotation, drilling rod drives and bored under drill bit, and sinks to drill bit and set Count stake bottom absolute altitude;
6) start the water pump on main frame drilling rod and inject water into drill bit bottom, so as to which mud is cleared up into mud pit;
7) Power Component lifting drilling rod, drilling rod is promoted to design stake top absolute altitude, one-step pore-creating;
8) second group is moved to continue to construct.
