Description
Technical field
It the utility model is related to a kind of Novel non-excavation rock reamer.
Background technology
With the fast development of social economy, the continuous improvement of technical merit, trenchless technology is using more and more extensive.
It is also more and more common using trenchless technology progress pipeline laying construction in lithostratigraphy.Rock reamer is essential applies
Work instrument.Industry practitioner devises various forms of lithosphere reamers.Using being more widely that one kind is referred from stone
The cone reamer that three gear wheel Technology designs of oily drilling applications go out.This reamer lacks of both existing in use
Fall into, first, the sliding bearing position of gear wheel is in the position of reamer and hole wall friction, and protect deficiency, it is easy to which abrasion causes axle
Damage is held, service life is short；Second, this cone reamer all uses single fulcrum support mode, once this fulcrum stress is excessive
Or abrasion may result in cone shedding, and great risk is brought to construction.Problem of both the above is badly in need of solving.
Utility model content
The purpose of this utility model is to provide a kind of Novel non-excavation rock reamer, with solve the above problems at least one
Individual aspect.
According to one side of the present utility model, there is provided a kind of Novel non-excavation rock reamer, including reamer central shaft,
Wear-resisting gusset, front and rear fixed plate and bicone cone structure, the wear-resisting gusset and reamer center axis connection, front and rear fixed plate
It is arranged on wear-resisting gusset, bicone cone structure is symmetrically located in front and rear fixed plate；The bicone cone structure includes
Resistance to roll flute, cone body, bearing, resistance to roll flute are embedded in cone body, fractured rock during use, before cone body is fixed on by bearing
On rear fixed plate；In use, bicone cone reamer can two-way reaming.
Preferably, the resistance to roll flute is hard-metal insert, and hard-metal insert is embedded in cone body by the way of impregnated.
Preferably, cone body is made of antifriction alloy, to carry hard-metal insert and bearing.
Preferably, the bearing is rolling and pushing tow double acting bearing, to cone body rotation and prevents from moving before and after gear wheel
It is dynamic.Bearing is under the protection of front and rear fixed plate and cone body, avoids rubbing with hole wall, whole gear wheel is in good
Operating condition, increase its service life.
Preferably, double fulcrum support modes are fixed in front and rear fixed plate before and after cone body uses, so that reamer makes
With the uniform force of process dens in dente wheel, and more strong point, when avoiding using to the full extent fracture, abrasion etc. cause to take off
Fall.
Preferably, front and rear fixed plate is fixed on reamer central shaft by the way of welding, and bicone cone structure is adopted
It is fixed on 2 points before and after the mode of welding in front and rear fixed plate, wear-resisting gusset connects central shaft and front and rear by the way of welding
Fixed plate.
Preferably, reamer central shaft is provided with hydrophthalmia, water flowing during for using.
The beneficial effects of the utility model are the bicone cone structure of the New Rock reamer and gear wheel support side
Formula avoids gear wheel abrasion in use, bearing damage, cone shedding etc., adds the service life of reamer, drop
Low construction risk.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of bicone cone structure.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Referring to Fig. 1, Fig. 2, in the present embodiment, resistance to roll flute 4, cone body 5, the three parts of bearing 6 composition bicone gear wheel in figure
Structure, resistance to roll flute 4 are hard-metal insert, are embedded in by the way of impregnated in cone body 5, fractured rock during using；Tooth
Wheel body 5 is made of antifriction alloy, to carry hard-metal insert and bearing 6；Bearing 6 is the bearing portions of gear wheel, to roll
With pushing tow double acting bearing, to cone body rotation and prevent gear wheel from moving forward and backward.
In use, bicone cone reamer can be with two-way reaming, can only a direction to solve existing cone reamer
The drawbacks of reaming.
The bearing portions of bicone gear wheel mechanism using be the protection in cone body 5 and front and rear fixed plate 3 all the time it
Under, bearing portions and rock contact are avoided and wear damage, so as to greatly prolong its service life.
The bicone cone structure being made up of resistance to roll flute 4, cone body 5, the three parts of bearing 6, is fixed by the way of welding
In front and rear fixed plate 3, i.e., double fulcrum support modes.This double fulcrum support modes are advantageous in that reamer uses process
In the stress of whole gear wheel be uniform, be different from single fulcrum support mode of existing cone reamer, avoid single fulcrum stress
The uneven situation for causing gear wheel damage to come off；And the more support tie point of double fulcrum supports, to prevent cone shedding from increasing
Add one layer of guarantee, reduce construction risk.
Front and rear fixed plate 3 is fixed on reamer central shaft 1 by the way of welding, by resistance to roll flute 4, cone body 5, bearing
The bicone cone structure of 6 three parts composition is fixed in front and rear fixed plate 3 for 2 points before and after by the way of welding, wear-resisting gusset
2 connect central shaft 1 and fixed plate 3 by the way of welding, and to strengthen fixed plate 3, reamer central shaft is provided with hydrophthalmia, use
Water flowing during using.
Above example simply elaborates general principle and characteristic of the present utility model, and the utility model is not by above-mentioned implementation
Example limitation, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change and change, these
Changes and modifications are both fallen within claimed the scope of the utility model.The utility model requires protection scope is by appended right
Claim and its equivalent thereof.
