Summary of the invention

Regarding the issue above, the present invention provides a kind of stake machine chain broaching of cutting teeth rational deployment.

In order to achieve the above objectives, present invention employs following technical proposals：A kind of stake chain formula of cutting teeth rational deployment Drill bit, including chain rack, the chain rack are equipped at least one chain type carrier, and the chain type carrier is equipped with several cut Cut tooth, the outer end of the cutting teeth protrudes from chain type carrier and towards the outside of chain type carrier, the chain type carrier and chain Between rack be equipped with chain-drive mechanism with drive chain type carrier in chain rack circumferentially revolution or reciprocally swinging；

At least one column are set on the chain type carrier along the cutting teeth of chain type carrier lengths directional spreding, it is adjacent each There are casting gaps between the cutting teeth of column.

The present invention cutting teeth will be directly arranged onto chain type carrier one by one, the position of small size and independent cutting teeth Randomness becomes strong, can be arranged in more reasonablely on chain type carrier.It, can be in chain since the size of cutting teeth is smaller An at least column cutting teeth is set on formula carrier, greatly improves chain type carrier and fineness is stirred to the cutting and grinding of ground.Adjacent each column Cutter should not be excessively close, impacted to avoid to casting.But it should not also dredge excessively, in order to avoid influence to excavate efficiency or influence horizontal To size.

In above-mentioned stake machine chain broaching, each cutting teeth face in adjacent each column cutting teeth is arranged or shifts to install.

In above-mentioned stake machine chain broaching, the extension direction of the cutting teeth is parallel with the traffic direction of cutting teeth, The equivalent cutting width of the cutting teeth is greater than the thickness of cutting teeth.

In above-mentioned stake machine chain broaching, the extension direction of the cutting teeth and the traffic direction of cutting teeth are in sharp Angle setting, the equivalent cutting width of the cutting teeth are greater than the thickness of cutting teeth.

Cutting teeth outer end is greater than the thickness of cutting teeth along the equivalent operation width in chain type carrier lengths direction, therefore can Effectively increase the excavation size of single cutting teeth, to improve excavation efficiency；Size becomes smaller, cutting teeth outer end is in prolate type, cuts It cuts tooth and arranges that more reasonable, excavation is high-efficient, these can largely improve cutting teeth and imitate to the crushing of ground Rate.Equivalent operation width refers to that cutting teeth is excavated the summation of the practical excavation width at position in cutting.If cutting teeth is formed Excavated position be it is continuous, then equivalent operation width is the width for being excavated position；If cutting teeth formed by excavation portion Position be it is discrete, then equivalent operation width be by excavate position the sum of the width of each section.

It is apparent that equivalent operation width of the cutting teeth outer end along chain type carrier lengths direction does not exceed cutting teeth outer end The size of length direction.And when equivalent operation width is equal to the size of cutting teeth outer end length direction, cutting teeth is laterally Setting, it is higher to the requirement of mechanical strength of cutting teeth at this time.

It realizes that equivalent operation width of the cutting teeth outer end along chain type carrier lengths direction is greater than the present invention provides two kinds to cut The method for cutting transverse tooth thickness degree：First, the cutting teeth outer end is made of flaky material in the present invention, the cutting teeth outer end Length direction is parallel to the setting of chain type carrier lengths direction, and the cutting teeth outer end is laterally curved to chain type carrier lengths direction Folding and/or torsion.On the one hand, cutting teeth outer end made of flaky material can more rapidly, be more successfully cut into soil layer, To the good crushing effect of ground；On the other hand, the equivalent operation width that bending and/or torsion realize cutting teeth outer end is greater than Cutting teeth thickness improves excavation efficiency, effectively reduces energy consumption；Finally, bending and/or torsion can also be formed on cutting teeth Casting face not only contributes to casting, refines convenient for the soil body；It also helps and subsequent stirring operation is carried out to the soil body dug down.Bending And only there are difference, bending part and cutting teeths for the connecting portion between bending part and torsional part and cutting teeth outer end for torsion There are apparent angles for connecting portion between outer end, and the connecting portion between torsional part and cutting teeth outer end is then more round It is sliding, there is a round slip surface transition, reduce stress and concentrate, there are advantages in structural strength.

Second, the cutting teeth outer end is made of flaky material in the present invention, the cutting teeth outer end length side To with the setting at an acute angle of chain type carrier lengths direction.Cutting teeth outer end is obliquely installed relative to chain type carrier lengths direction, The equivalent operation width for being able to achieve cutting teeth outer end is greater than cutting teeth thickness, can equally improve the excavation efficiency of cutting teeth.This Outside, cutting teeth outer end length direction and chain type carrier lengths direction setting at an acute angle substantially also forms casting face, not only has Conducive to casting, refined convenient for the soil body；It also helps and subsequent stirring operation is carried out to the soil body dug down.

In above-mentioned stake machine chain broaching, the cutting teeth outer end is laterally bent relative to cutting teeth traffic direction And/or torsional mode extends, to form casting face on cutting teeth.In the present invention, it is lateral inclined that cutting teeth is equipped at least one From in the casting face of cutting teeth direction of travel, and at least one casting is facing towards the side rear of cutting teeth direction of travel.It should say Bright, the generation type in casting face includes but is not limited to the " bending and/or torsion of cutting teeth outer end mentioned above herein The form of rotatable extension ", as long as the scheme that can guide the ground cut down to the side rear of cutting teeth direction of travel is equal It can.

It, can be along the casting face by the ground under cutting teeth cutting after above-mentioned casting face is set on cutting teeth It is tossed to the side rear of cutting teeth, had both avoided and be cut rear ground and because being deposited at cutting teeth influence cutting process, make It is again hardened blocking at power loss, soil, it is refined convenient for the soil body, ground crush efficiency is improved.Meanwhile to digging down The soil body carry out in subsequent stirring operation process, the setting in casting face so that the soil body, cement slurry etc. along the casting face quilt It throws to the side rear of work department, is conducive to improve mixed effect.

In above-mentioned stake machine chain broaching, the angle phase of the bending of the cutting teeth outer end and/or torsional mode extension It is at an acute angle for cutting teeth traffic direction.This structure is conducive to improve casting efficiency, and cutting teeth stress is more reasonable.Make To be preferred, the angle of the bending of the cutting teeth outer end and/or torsional mode extension is in 30 ° relative to cutting teeth traffic direction ~60 ° of angle.

In above-mentioned stake machine chain broaching, each cutting teeth outer end in adjacent each column cutting teeth is in the same direction and/or incorgruous curved Folding and/or torsion.

In above-mentioned stake machine chain broaching, the cutting teeth is spaced at least two directions in chain rack to be divided Cloth.

In above-mentioned stake machine chain broaching, the quantity of the chain type carrier is no less than two, wherein at least two chain The traffic direction of formula carrier on the contrary, and the torque that generates of the revolution of each chain type carrier or reciprocally swinging repeal by implication or at least partly Payment.

Compared with prior art, it is the advantages of this chain broaching：

(1) cutting teeth is converted to small size by large scale, effectively reduces stress, reduces energy consumption, and stir using chain type It can be reduced the effective area that drill bit enters the soil body, it is possible to reduce the replacement rate of original soil body effectively reduces brought by displacement mud Pollution.And the Randomness of position of small size and independent cutting teeth becomes strong, can be arranged into drill bit of pile machine chain more reasonablely On knife, and the chain broaching cutting teeth of more stake machines can be installed on identical chain type carrier, so not only The excavation efficiency of chain broaching cutting teeth is improved, and ground crush efficiency also further increases, so as to improve cement The structural strength of mixing pile avoids the occurrence of floating stake and significantly reduces the extruding to periphery ground.

(2) present invention cutting teeth will be directly arranged onto chain type carrier one by one, the position of small size and independent cutting teeth It sets randomness and becomes strong, can be arranged in more reasonablely on chain type carrier.It, can be since the size of cutting teeth is smaller An at least column cutting teeth is set on chain type carrier, greatly improves chain type carrier and fineness is stirred to the cutting and grinding of ground.

As shown in FIG. 1 to FIG. 3, Figure 17~Figure 23, the stake machine chain broaching of the present embodiment is that type is sufficiently stirred in a kind of soil body Chain broaching comprising chain rack 1a, chain rack 1a is connected with drilling rod 100, positioned at 100 lower part of drilling rod, drilling rod 100 therein It can be single-unit or Multi-section retractable structure；Chain rack 1a is equipped at least one chain type carrier, and chain type carrier is equipped with several use In the bulge-structure of cutting soil, concretely cutting teeth 3, the outer end of cutting teeth 3 protrude from chain type carrier；Chain rack 1a It is equipped with power device 205, wherein power device 205 is connected with chain-drive mechanism 204, and chain-drive mechanism 204 is for driving Chain type carrier circumferentially turns round on chain rack 1a or reciprocally swinging.

The drill bit of the present embodiment is located at 100 lower part of drilling rod, and (power device is set up directly on using underlying power drive On drill bit), the underlying power that thoroughly solves of power is arranged in the brought security risk in the sub- top end part of stake rack, especially drill bit Requirement of the torsion to shelf intensity and drilling rod bending strength；The diameter for reducing drilling rod, can drill out the stake of small-bore in this way；It adopts Torque can be more effectively transmitted with the underlying drill bit of power, reduces power loss；The power to power device 205 is postponed under power It is required that becoming smaller, even if only existing dynamic 1/50th also can easily drive；The cutting of power underlying cooperation chain type can be with Effectively the soil body is shredded, enables cement and the soil body to be more fully blended in one, improves the performance of mixing pile；Using dynamic Power is underlying can be used cooperatively telescopic drill rod, can not have to stacks in this way, greatly improve drilling efficiency.

In the present embodiment, chain type carrier can be chain, can also be replaced with crawler belt, the isostructural other chain type carriers of chain Generation；In addition to annular, chain type carrier can also be bar shaped.Wherein, when chain type carrier is annular or bar shaped chain, structure and function Can be：When for ring chain 1, around being supported on corresponding drive sprocket 1b and driven gear 1c, movement can be turned round, It drives cutting teeth 3 to act during revolution movement, realizes and excavate；When for bar shaped chain, both ends are fixed respectively and are wound on phase It answers and carries out folding and unfolding on drive sprocket 1b or driven sprocket 1c, or connection cam structure, it is possible thereby to reciprocating action, past Double action drives cutting teeth 3 to act during making, and realizes and excavates.

Cutting teeth 3 in the present embodiment can be the multiple tooth structure of saw blade-shaped, be also possible to the anodontia of blade-shaped or few tooth Structure (for ease of description, uses sometimes the latter " cutter " this nickname) in this application, the cutting of both structures Tooth 3 can bend or reverse to the side of chain type carrier traffic direction, thus increase the equivalent cutting width of cutting teeth 3.

Without loss of generality, in following contents, the present embodiment carries out stake machine chain broaching by taking ring chain 1 as an example It introduces.

The chain-drive mechanism 204 of the present embodiment includes the drive sprocket 1b and driven sprocket 1c on chain rack 1a, ring Shape chain 1 is set around on drive sprocket 1b and driven sprocket 1c.Herein, drive sprocket 1b and driven sprocket 1c is in chain rack 1a On installation site do not limit, such as：Drive sprocket 1b may be above driven sprocket 1c, also may be at driven sprocket 1c Lower section.It is needed when two drive sprocket 1b are arranged using differential further, it is also possible to which two drive sprocket 1b are arranged simultaneously Device, differential mechanism are arranged between two drive sprocket 1b.

In the present embodiment, chain rack 1a is played a role as the load bearing component of ring chain 1, therefore its form It can be multiplicity, specifically can be attachment base, flange, connection frame etc..For example, chain rack 1a can be such as Fig. 1 to Fig. 3 institute Show be wholely set, the rod chair mechanisms of multistage bending (for simplicity, are related to this chain rack 1a in following the description When form, the abbreviation of " drill headstock " is also used), drill headstock is advantageous in that convenient for the layout of a plurality of ring chain 1, avoids producing Raw interference；It can certainly be other structures form, be subject to and be suitble to arrangement ring chain 1.

Using when chain rack 1a structure, several ring chains 1 are equipped on chain rack 1a (preferably shown in Fig. 1~3 It is multiple), power device 205 can be arranged directly in the cabinet of chain rack 1a.Drive scheme i.e. underlying using power, At this time it is necessary to optimize to sealing, particular content can be with further reference to the description hereafter to power device sealing structure.

As shown in Figures 1 to 3, power device 205 includes multiple driving mechanisms 11 (can be hydraulic motor or motor etc.), Driving mechanism 11 is arranged in a one-to-one correspondence with the drive sprocket 1b of each ring chain 1 to be connected, and is respectively mounted in each driving mechanism 11 There is a drive sprocket 1b, for driving a ring chain 1；And driving mechanism 11 on chain rack 1a from top to bottom according to Secondary setting requires in this way convenient for meeting the space layout on chain rack 1a.Multiple driving machines are configured in this power device 205 Structure 11, traffic direction, speed convenient for each ring chain 1 of independent control.

It herein, it will be appreciated by those skilled in the art that should there are certain intervals between different driving mechanism 11.Specifically Ground, each driving mechanism 11 are from top to bottom set gradually on chain rack 1a, this allows for each driving mechanism 11 can be in longitudinal direction Layout, advantageously reduces the lateral dimension of entire drill bit.

Using when chain rack 1a structure, chain rack 1a includes at least two sections of rod cabinets (such as Fig. 2 institute shown in Fig. 1~3 The chain rack 1a shown includes four sections), each rod cabinet 1aa can be in Different Plane, two be disposed adjacent section rod It is connected between cabinet 1aa by bending part 1ab；The overbending direction of adjacent bend 1ab can be identical, can also part it is identical, Part is opposite (for example, in Fig. 1, first, second and third section is rolled over to the first lateral bending respectively, and the 4th section reversely bends to the other side), respectively Driving mechanism 11 is separately positioned in different sections of rod cabinet 1aa；Each bending part 1ab can with adjacent rod cabinet 1aa is arranged at obtuse angle, and each bending part 1ab all has towards the outer inclined-plane 1ac in drilling rod direction and extends towards chain rack The outer inclined-plane 1ad in direction, the outer inclined-plane 1ad of the top of each ring chain 1 respectively close to corresponding bending part 1ab.

In Fig. 2, chain rack 1a is four sections of bendings, and wherein first three section is bent in the same direction, and the 4th section towards other direction Reversed bending, therefore it is drive sprocket 1b that driving mechanism 11 can be arranged on one~tetra- section of rod case respectively, and the 4th Shared driven sprocket 1c is set in section, not will form interference when being arranged so ring chain 1.Certainly, this multistage is bent The number of segment of chain rack 1a can be adjusted with chain number, be subject to and ring chain 1 is not caused to interfere.

In FIG. 1 to FIG. 3, driving mechanism 11 be it is multiple, drive sprocket 1b or driven sprocket 1c be also it is multiple, they point It is not correspondingly arranged with corresponding ring chain 1.It is understood that the driving mechanism 11 of each ring chain 1, drive sprocket 1b or driven sprocket 1c can also be shared, and need the drive sprocket 1b that will be shared or driven sprocket 1c to be coaxially disposed at this time, this side Formula can save equipment cost, but can only realize in the same direction, synchronized, the synchronous driving of each chain；In order to realize that torque offsets Or part is offseted, shared driving mechanism 11, drive sprocket 1b or driven sprocket 1c should have at least two sets.

In addition, chain rack 1a can also be and connect frame as shown in Figure 17 to Figure 27, a chain rack 1a is for installing one A ring chain 1 can be connected with each other between chain rack 1a corresponding to different ring chains 1；Using the chain machine of this form When frame 1a, driving mechanism 11 can be set the top in each ring chain 1 and by transmission component and ring chain 1 phase one by one Even；Driving mechanism 11 also can be set in the gap between adjacent annular chain 1.

Certainly, chain rack 1a, ring chain 1 can also be using other usual manners substitutions outside the present embodiment.In addition, The set-up mode of ring chain 1 and the connection of driving mechanism 11, the connection type of chain rack 1a and drilling rod, driving mechanism 11 Other usual manners outside the present embodiment can be used.

Similarly, it should be readily apparent to one skilled in the art that chain rack 1a is in the connection mount structure using Figure 17~Figure 27 When, driving mechanism 11, drive sprocket 1b or the driven sprocket 1c of each ring chain 1 equally can be shared or are separately provided, no It repeats again.

In the present embodiment, ring chain 1 should have at least one, be mounted to the cutting teeth 3 of array distribution above, by This constitutes a plurality of cutting body units.In this way, the soil body is cut in these cutting body unit realizations when ring chain 1 rotates It cuts, crush and stirs.

Chain type carrier is excavated pair in circumferentially revolution or during reciprocally swinging (i.e. in digging process) on drill headstock Chain type carrier is acted on as reaction torque can be generated, and this reaction force is transmitted on drill headstock by chain type carrier.If It takes no action to be balanced, this reaction force can be such that drill headstock moves against the direction of motion of chain type carrier.Therefore this implementation In example, ring chain 1 preferably has at least two, and the direction that at least two ring chains 1 circumferentially turn round on chain rack 1a On the contrary, and the torque that generates of the circumferential revolution of each ring chain 1 repeal by implication or at least partly offset.Adjacent two ring chains The distance between 1 can reduce as much as possible to guarantee to excavate efficiency, only it is noted that not allowing on adjacent two ring chains 1 Cutting teeth 3 is encountered.

When using previous bit seat as chain rack 1a, since driving mechanism 11 is that the difference in chain rack 1a is high It spends on position, it will be appreciated by those skilled in the art that height herein refers to the drill bit driving mechanism 11 in a state of use Center where relative position, therefore in the same side of chain rack 1a, the chain length of different ring chains 1 is different , in order to guarantee that torque payment is balanced, need the installation side by each driving mechanism 11 and drive sprocket 1b on chain rack 1a To well-designed according to the length of ring chain 1 with installation site.Four are provided in drill bit of pile machine as shown in FIG. 1 to 3 Longest ring chain 1 and shortest ring chain 1 are mounted on the same side of chain rack 1a by ring chain 1, the present embodiment And the direction circumferentially turned round on chain rack 1a is identical, long ring chain 1 is then mounted on the another of chain rack 1a in remaining two The side and direction circumferentially turned round on chain rack 1a is identical, but the ring chain 1 in chain rack 1a opposite sides is in chain machine The direction circumferentially turned round on frame 1a is balance opposite, that so certifiable chain rack 1a is subject to.
