Description
Technical field
The utility model belongs to building implements technical field, relates to the inside and outside drilling rod reversing arrangement of a kind of bi-directional cement soil fourth type mixing pile machine.
Background technology
Soft Ground in building foundation engineering is the key link that guarantees workmanship, and occupies larger proportion in engineering total price.A large amount of engineering practices show, the method for mixing cement and soil into pile have construction simple, fast, vibrate the advantages such as little, can effectively improve the stability of soft foundation, reduce and control settling amount.Cement mixing method has now developed into a kind of conventional Treatment Methods of Soft Ground, is mainly applicable to reinforce saturated soft clay foundation.It specifically utilizes the materials such as cement (or lime) as curing compound, by special Mixing Machine, in ground depths, on the spot by weak soil and curing compound action of forced stirring, by producing a series of physical and chemical reaction between curing compound and weak soil, weak soil is hardened into the cement mixing method with globality, water stability and some strength, this cement mixing method forms composite foundation together with all soil of stake, thereby raising bearing capacity of foundation soil, reduces foundation settlement.At present, what a stake mechanomotive force speed reducer output shaft bearing adopted is deep groove ball bearing, it is main that deep groove ball bearing mainly bears radial load, bear a certain amount of axial load simultaneously, deep groove ball bearing is when bearing axial load, and steel ball and axial load are excessive, and Contact Ellipse will be clipped a part by lasso rib, thereby near the generation stress of contact position steel ball and ring washer limit is concentrated, causes bearing beginning of fatigue failure.
Utility model content
For addressing the above problem, the utility model provides a kind of bi-directional cement soil fourth type mixing pile machine inside and outside drilling rod reversing arrangement, and the technical scheme adopting is as follows:
The inside and outside drilling rod reversing arrangement of a kind of bi-directional cement soil fourth type mixing pile machine, comprise interior drilling rod, outer drilling rod, described interior drilling rod, outer drilling rod bottom outside are provided with blade, on interior drilling rod, connect interior drilling rod flange and output flange, interior drilling rod flange is provided with output flange outside the long-neck sleeve flange being connected with outer drilling rod, at long-neck sleeve flange top, is provided with bearing bag, in bearing bag, is provided with pedestal, pedestal and power transmission shaft are connected, and bearing bag inner bearing platform upper and lower end is provided with bearing group; The bearing portion of wrapping is provided with bearing cover, input flange successively.
At bearing cover top, be provided with bearing clearance and adjust bolt group, improve bearing rotation precision and supporting capacity, reduction driveline vibrations and noise.
Described bearing group middle (center) bearing circle of position taper roller bearing, taper roll bearing can bear larger axial load.
The beneficial effects of the utility model are: by bearing bag is set, in bearing bag, adopt two groups of taper roll bearings can bear larger axial load, solve deep groove ball bearing when bearing axial load, steel ball and axial load are excessive, Contact Ellipse will be clipped a part by lasso rib, thereby near the generation stress of contact position steel ball and ring washer limit is concentrated, cause the problem of bearing beginning of fatigue failure; On bearing cover, be provided with bearing clearance simultaneously and adjust bolt group, improve bearing rotation precision and supporting capacity, reduction driveline vibrations and noise, novel, rational in infrastructure, easy to assembly, be convenient to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, drilling rod reversing arrangement inside and outside a kind of bi-directional cement soil nail of the utility model type mixing pile machine is described in further detail.
As shown in Figure 1, the inside and outside drilling rod reversing arrangement of a kind of bi-directional cement soil fourth type mixing pile machine, comprise interior drilling rod 1, outer drilling rod 2, described interior drilling rod 1, outer drilling rod 2 bottom outside are provided with blade, on interior drilling rod 1, connect interior drilling rod flange 3 and output flange 4, interior drilling rod flange 3 is provided with output flange 4 outsides the long-neck sleeve flange 5 being connected with outer drilling rod 2, at long-neck sleeve flange 5 tops, be provided with bearing bag 6, in bearing bag 6, be provided with pedestal 7, pedestal 7 is connected with power transmission shaft, and bearing bag 6 inner bearing platform 7 upper and lower ends are provided with bearing group 8; Bearing bag 6 tops are provided with bearing cover 9, input flange 10 successively.
At bearing cover 9 tops, be provided with bearing clearance and adjust bolt group 11, improve bearing rotation precision and supporting capacity, reduction driveline vibrations and noise.
Described bearing group 8 middle (center) bearing circle of position taper roller bearings, taper roll bearing can bear larger axial load.
During work:
Input flange 10 is by power transmission to output flange 4, and output flange 4 drives interior drilling rod flange 3 and the 1 operation work of interior drilling rod; Input flange 10 goes out to be defeated by bearing bag 6 by power simultaneously, and bearing bag 6 drives long-neck sleeve flange 5 and the 2 operation work of outer drilling rod, and long-neck sleeve flange 5 tops are provided with bearing bag 6, be provided with pedestal 7 and bearing group 8, thereby can bear larger axial load in bearing bag 6; The bearing cover 9 at bearing bag 6 tops is provided with bearing clearance and adjusts bolt group 11, by regulating bearing clearance to adjust bolt group 11, improves bearing rotation precision and supporting capacity, reduction driveline vibrations and noise.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
