Description
Technical field:
The utility model relates to a kind of boring guncreting mechanical agitation bottom expanding drill.
Background technology:
What the building pile foundation engineering was used at present is that drilled pressure filling pile stirs bottom expanding drill, and the shortcoming of this drill bit is:
1, because machinery expands end power set is installed on the drill bit, it is big to cause drill bit to cut native area, and it is big to creep into resistance, creeps into very difficulty, with there not being low one times of the end of expansion device drill bit phase specific efficiency.
2, adopt hydraulic jack to drive owing to expand end Mechanical Driven power, when hydraulic jack stretches out stirring,, produce leakage of oil, reduced the life-span of hydraulic jack with coagulation soil phase friction wear.
3, hydraulic oil pipe is arranged in the drilling rod outside and is led to drill bit, very easily wearing and tearing.
4, the hydraulic gyration head is poorly sealed, leakage of oil easily.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, fault is few, rate of penetration is fast, the boring guncreting mechanical agitation bottom expanding drill made easily.
Above-mentioned purpose realizes by following technical scheme:
Boring guncreting mechanical agitation bottom expanding drill, its composition comprises: unit head, described unit head connects hydraulic jack, fixing saddle, described hydraulic jack connects the pivoting support cover, described pivoting support cover connects excessive joint, wire rope respectively, described wire rope connects brill and expands dual-purpose drill bit plate, and described brill expands dual-purpose drill bit plate and connects hollow drill, and described brill expands dual-purpose drill bit plate and is installed in the anti-button clamping plate by hinge.
Described boring guncreting mechanical agitation bottom expanding drill, described pivoting support cover comprises the supporting ectosome, described supporting ectosome and described hydraulic jack lower end are hinged, and described supporting ectosome is connected by steel ball with the revolution endosome, welds sliding sleeve on the described revolution endosome.
The beneficial effects of the utility model:
1. the utility model can utilize original long screw auger tool, increases mechanical agitation and expands end device, and is simple in structure, makes easily, and cost is low, and is easy to use, fault-free.
2. creep into, mechanical agitation expands end pile and once finishes, when drilling to completion, start machinery and expand end device, can make two drill bit plates whiles of drill bit carry out the mechanical agitation expansion end, reach the purpose that increases a stake end area, raising supporting capacity, reduction construction costs to the both sides extension.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is the partial structurtes enlarged drawings at A place shown in the accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Boring guncreting mechanical agitation bottom expanding drill, its composition comprises: unit head 1, described unit head connects hydraulic jack 2, fixing saddle 5, described hydraulic jack connects pivoting support cover 3, described pivoting support cover connects excessive joint 4, wire rope 6 respectively, described wire rope connects brill and expands dual-purpose drill bit plate 8, and described brill expands dual-purpose drill bit plate and connects hollow drill 7, and described brill expands dual-purpose drill bit plate and is installed in the anti-button clamping plate 10 by hinge 9.
Described boring guncreting mechanical agitation bottom expanding drill, described pivoting support cover comprises supporting ectosome 11, described supporting ectosome and described hydraulic jack lower end are hinged, and described supporting ectosome is connected by steel ball 13 with revolution endosome 12, welding sliding sleeve 14 on the described revolution endosome.Sliding sleeve is connected on being welded on and forming one and wire rope on the revolution endosome, fixedly the supporting ectosome of saddle lower end control pivoting support cover, revolution endosome, steel ball, slide on the excessive joint and slide up and down, bore and expand dual-purpose drill bit plate and be installed in the anti-button clamping plate by hinge and overturn to both sides.Raceway is filled steel ball between described supporting ectosome and the revolution endosome, plays the effect of bearing.
Described pivoting support cover can substitute or about cover the friction type substitutes with bearing, and the wire rope that expands dual-purpose drill bit plate is bored in pulling can be installed in that hollow drill core pipe is inboard to be got out and be attached thereto or adopt shaped steel to substitute wire rope to boring the dual-purpose drill bit plate of expansion place; Can cancel the wire rope of a side, using a side wire rope to spur a sidetracking head plate still has the expansion of boring effect, and anti-button clamping plate should satisfy brill and expand the anti-torsional strength requirement when overturn in both sides of dual-purpose drill bit plate.
The utility model implementation process is: the supporting ectosome by the fixedly saddle that is fixed on the unit head lower end, pivoting support cover does not change, raceway is filled steel ball rolling connection between supporting ectosome and the revolution endosome, revolution endosome and sliding sleeve are welded as a whole with the hollow drill rotation, regain pulling pivoting support cover when being hung in unit head, lower end hydraulic jack.Upwards slide on transit joint, the pulling wire rope drives to bore and expands dual-purpose drill bit plate, with the hinge be the center of circle in anti-button clamping plate to outer extension, be rotated mechanical agitation and expand after the end finishes, regain hydraulic jack, loosen wire rope fall bore to expand dual-purpose drill bit plate after, drilling tool is proposed.
