Description
Technical field
This utility model belongs to cohesive soil and coastal area soft soil layer cast-in-situ bored pile diving drill machine drilling construction technology
A kind of field, and in particular to control device for improving diving drill machine perpendicularity.
Background technology
It is diving drill machine simple structure, high working efficiency, low cost, practical, have under the conditions of saturated soft ground
Unique advantage.But just because of its simple structure, degree control is undesirable, especially for the longer place of empty stake（Empty stake is long
Degree is more than 8m）, the technique is typically all used with caution, it is relatively costly according to rotary drilling rig, govern the type selecting of pore-forming technique.
The content of the invention
During this utility model place drilling construction longer in order to solve empty stake, using vertical during diving drill machine pore-forming
The undesirable problem of degree control, and then there is provided a kind of control device for improving diving drill machine perpendicularity.
This utility model is adopted the following technical scheme that：
A kind of control device for improving diving drill machine perpendicularity, including it is some for being set with consolidating for diving drill machine motor
Determine ring, retainer ring be arranged in parallel and the center of circle is coaxial, by some vertically arranged gag lever post connections between retainer ring, gag lever post connects
It is connected to the outside of retainer ring.
The retainer ring includes inner ring and outer ring, and gag lever post is connected to outer ring outside, by some between inner ring and outer ring
Connecting plate connects, and inner ring diameter is equal with motor diameter, and for clamping diving drill machine, race diameter is straight with the pore-forming of diving drill machine
Footpath is equal, and when inclining occurs in drill bit, gag lever post is contacted with hole wall, suppresses the inclination of drilling power set, realizes hanging down drilling
The control of straight degree.
The retainer ring is spliced by bolt by two shapes, equal sized semicircular ring, is easy to job site
Fabrication and installation.
The upper and lower ends of the gag lever post prevent gag lever post in drilling process from turning up obstruction to the center of circle side indent of retainer ring
Drilling construction, the top of gag lever post is higher by the mounting flange of motor and drilling rod, realizes the abundant parcel to creeping into power set
Control, the bottom of gag lever post prevents gag lever post and bit contact higher than the drill bit top surface of diving drill machine, affects the work of drill bit.
This utility model has the advantages that：
1st, position-limiting action can be formed to diving drill machine drill bit and power set, crept into using this utility model control device
Cheng Zhong, the gag lever post of the device contacts to form constraint with hole wall, effectively inhibits the deflection of power set, obtains borehole perpendicularity
To control；
2nd, the device can be made by leftover pieces such as the channel-section steel of job site, steel plates, low cost, and manufacturing process is easy；
3rd, the size of retainer ring can be designed and produced according to motor model and drilling diameter, can operate with different diving drill machines
Or similar underground construction device, and the device by two parts splicing constitute, it is easy for installation, be adapted to promote the use of.

Fig. 2 is A-A sectional views；
In figure：1- retainer rings, 2- gag lever posts, 3- drilling rods, 4- ring flanges, 5- motors, 6- decelerators, 7- drill bits, 8- connections
Plate.
Specific embodiment
With reference to accompanying drawing, specific embodiment of the present utility model is described further：
The control device for improving diving drill machine perpendicularity as shown in Figure 1, 2, including it is some for suit diving brill
The retainer ring 1 of electromechanical machine 5, retainer ring 1 be arranged in parallel and the center of circle is coaxial, by some vertically arranged spacing between retainer ring 1
Bar 2 connects, and gag lever post 2 is connected to the outside of retainer ring 1.
Principle of the present utility model is：The ring-type perpendicularity equal with aperture is assembled into by installing gag lever post and retainer ring additional
Control device, is fixedly secured with submersible motor, when in uneven soil layer drilling, when inclining occurs in drill bit, gag lever post connects with hole wall
Touch, by the effect of contraction of hole wall soil layer, effectively suppress the deflection of power set, controlled borehole perpendicularity.
The gag lever post can adopt 10# channel-section steels, retainer ring and connecting plate to be 8mm steel plates, fix for ease of installing, and hang down
Straight degree control device point two parts are fabricated separately, and diving drill machine outside is fixed on by bolt assembly when using.Specifically made
Journey is as follows：
The first step：4 gag lever posts of equal length are intercepted on 10# channel-section steels, 1500 ~ 2000mm of length, upper and lower ends portion omits
Bend up, prevent obstruction drill bit drilling of turning up in drilling process；
Second step：Inner ring stationary half is rolled with 8mm steel plates, diameter is with submersible motor external diameter, two ends and reserved splicing
Ear；
3rd step：Outer ring stationary half, the same boring aperture of diameter are made, and is welded with inner ring stationary half；
4th step：It is welded with fixed connecting plate；
5th step：Gag lever post and the welding of outer ring stationary half；
6th step：The vertical control device bolt assembly of the two parts made is fixed on into diving drill machine outside.
