Description
Technical field
It the utility model is related to a kind of drill bit of rotary drilling rig, more particularly to a kind of rotary drilling rig for interlocking pile operation
Drill bit.
Background technology
Hole-drilling interlocking pile refers to the armored concrete " piling wall " that adjacent studs are mutually twisted and formed between the campshed of horizontal layout
Deep foundation pit supporting structure for structures.Hole-drilling interlocking pile " piling wall " is different from " piling wall " that circular stake is combined with shaped pile,
After the concrete final set of interlocking pile appears in the occlusion of stake, turn into seamless continuous " piling wall "；It is arranged with common drilling supporting
Stake is compared, and the shearing strength and security of supporting construction is greatly improved；It has the good performance that intercepts water, and is not required to commonly bore
The auxiliary of hole campshed intercept water and stake between earth-retaining measure.
Hole-drilling interlocking pile is the stake that both sides are first completed with ordinary skill, and the then stake to centre carries out operation, prior art
In stake to centre when carrying out operation, the reserved space of middle stake is bigger than normal, and drilling tool need to creep into simultaneously cutting cement and
Soil layer, enters that tooth speed is slow, and bit force is uneven, and the left-right deviation that causes to drill is larger, and the interlocking pile stability formed is poor.
So that single stake is diameter 800mm stake as an example, traditional technology is first to complete the stake on both sides, reserves 1200mm's between two stakes
Distance, then when the stake to centre carries out operation, drilling tool easily has influence on the quality of interlocking pile because of discontinuity.
Utility model content
The purpose of this utility model is to provide a kind of drill bit of the rotary drilling rig for interlocking pile operation solve occlusion
The problem of entering slow tooth speed and rig discontinuity in stake operation.
In order to solve the above problems, the utility model provides a kind of drill bit of the rotary drilling rig for interlocking pile operation,
It is flexibly connected including reaming cylinder brill, the cylinder of its first end connection reaming cylinder brill, the second end located at cylinder and with cylinder
Bottom plate, both ends connect respectively reaming cylinder bore and cylinder and for control bottom plate opening and closing unlocking mechanism and connection reaming cylinder
The tooth plate that enters with cylinder is bored, folding hole is formed on the bottom plate and an opening-closing plate is connected at folding hole, the reaming cylinder bores, bottom
Plate and enter on tooth plate to be equipped with brill tooth, close to entering to form charging aperture at tooth plate on the cylinder.
Further, the unlocking mechanism and including the elastic component on reaming cylinder brill and through elastic component be flexibly connected
The motion bar of one buckle, the buckle be movably connected on the inner side of the cylinder and with bottom plate clamping.
Further, the end face that the reaming cylinder bores is provided with rig connecting seat.
Further, the buckle l-shaped.
Further, the guide of connection motion bar is provided with the inside of the cylinder.
Compared with prior art, there is following technique effect in the utility model：
The utility model provides a kind of drill bit of rotary drilling rig for interlocking pile operation, using single stake as diameter 800mm
Stake exemplified by, first complete both sides stake after, between two stakes reserve 800mm distance, the cylinder is also 800mm,
When the stake to centre carries out operation, cylinder is responsible for carrying out mud layer operation, and reaming cylinder bores and entered concrete stake of the tooth plate to both sides
Operation is carried out, the design avoids a series of problems for boring tooth discontinuity and triggering, so as to improve into tooth speed；Making
During industry, cylinder both sides close to both sides stake, therefore run it is more stable.

Embodiment
Below in conjunction with accompanying drawing, lift a specific embodiment and described in detail.
As shown in figure 1, a kind of drill bit of rotary drilling rig for interlocking pile operation, including reaming cylinder bore 1, cylinder 2, bottom plate
3rd, tooth plate 5, opening-closing plate 4, spring 61, motion bar 62, guide 7, buckle 63 are entered.Wherein, reaming cylinder bores 1 one end open, opens
The periphery at mouth end is evenly equipped with brill tooth, and for creeping into concrete stake, the other end is provided with into radiation reinforcement, and is set at center
Connect the rig connecting seat 11 of rotary drilling rig.The first end of cylinder 2 is welded on reaming cylinder and bored on 1 reinforcement, and the of cylinder 2
Two ends are hinged bottom plate 3, and bottom plate 3 is centrally formed folding hole, and opening-closing plate 4 is hinged at the folding hole of bottom plate 3, and is located at cylinder
The inner side of body 2, the size of opening-closing plate 4 is more than the size of hole 31, therefore can only be rotated to the side of cylinder 2.The edge of bottom plate 3
On be provided with brill tooth, for creeping into mud layer, the inner side of bottom plate 3 is additionally provided with a clamping ring 32, for connection buckle 63.Cylinder 2
It is provided between reaming cylinder brill 1 into tooth plate 5, for creeping into concrete stake.Cylinder 2 close to enter tooth plate 5 at be provided with charging aperture 21,
The cement for being easy to drill out into tooth plate 5 enters in cylinder 2.Guide 7 is arranged on the inner side of cylinder 2, for being carried out to motion bar 62
It is oriented to.One end of spring 61 is fixed in reaming cylinder and bored on 1 reinforcement, and motion bar 62 runs through spring 61 and guide 7, motion bar
62 one end is provided with locking cap and is bonded with spring 61, the first movable end that the other end passes through bearing pin connection buckle 63.Buckle 63
L-shaped, be hinged in cylinder 2, the second movable end of buckle 63 formed projection and with the clamping of clamping ring 32 on bottom plate 3.It is above-mentioned
Spring 61, motion bar 62 and buckle 63 form unlocking mechanism.
By taking a diameter of 800mm of single pile as an example, in operation, first the pile on both sides is carried out with conventional art, two
The distance between axis of post is 1600mm, i.e. 800mm distance is reserved between two piles.Cylinder 2 from external diameter 800mm,
The drill bit that the external diameter that reaming cylinder bores 1 is 1200mm carries out operation.Under the driving of rotary drilling rig, pile of the cylinder 2 close to both sides
Mud layer is crept into, soil bores 1 and enter tooth plate 5 to both sides by entering cylinder 2, reaming cylinder at the hole 31 on bottom plate 3
Pile crept into, the cement fragment under boring enters cylinder 2 by charging aperture 21 on cylinder 2.After cylinder 2 is filled, lead to
Cross the drill bit that the application is related to by rotary drilling rig and be promoted to ground.The top of motion bar 62 is pressed, driving buckle 63 rotates, so as to
