The specific embodiment
Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.
The utlity model has the bidirectional guniting drilling bit of reversible rotation stirring function and the difference of drill bit in the past and be mainly reflected in the centre of drill bit, distribute one and can realize the cyclic train mechanism of blade counter-rotating, thereby drill bit forms the multilayer blade, and both forward and reverse directions stirs simultaneously, and pile quality is better.
See also shown in Figure 1ly, it is the bidirectional guniting drilling bit general structure schematic diagram that the utlity model has reversible rotation stirring function; It comprises: flare nut 1, and it is in order to being connected with drilling rod, and described flare nut is a hollow; Drill body, it is the utility model agent structure, it is disposed with drill bit tube 221, cyclic train mechanism 23 and following drill bit tube 222 from top to bottom, described drill bit tube 221 and described flare nut 1 Joint gone up; Drill bit 24, itself and described down drill bit tube 222 Joints; Describedly affixedly can adopt welding manner or one-body molded; Described going up on drill bit tube 221 and the following drill bit tube 222 is respectively arranged with positive rotating vane sheet 211,212, and described cyclic train mechanism 23 outer setting have the blade 232 of counter-rotating.
After passing to the bidirectional guniting drilling bit that the utlity model has reversible rotation stirring function when power, the described positive rotating vane sheet 211,212 that is provided with on drill bit tube 221 and the following drill bit tube 222 of going up begins just to change, described counter-rotating blade 232 begins counter-rotating, thereby realizes creeping into the purpose with two-way stirring.
See also shown in Figure 2ly, it is to the utlity model has cyclic train organization gear mesh schematic representation in the bidirectional guniting drilling bit of reversible rotation stirring function; For the utility model, described cyclic train mechanism 23 is exactly a core texture, but need to prove the application that described cyclic train mechanism 23 comes down to epicyclic train, and epicyclic train is the known a kind of structure of mechanical transmission fields to those skilled in the art, therefore how this specific embodiment only realizes that at it the present utility model purpose sets forth, it comprises: the planet carrier (not shown), its two ends weld together with following drill bit tube with the described drill bit tube of going up respectively, and are arranged in the described gear ring blade cover 2311; Sun gear 2312, it is positioned in the middle of the described planet carrier, and fixedlys connected with the slip casting core pipe of described drilling rod inside; Planetary gear set, it is meshed with described sun gear, and it comprises planetary gear 1 and planetary gear 2 2314 at least; Described gear ring blade cover 2311 is set in described planetary gear set outside and is meshed with it; Described counter-rotating blade 232 is welded on the described gear ring blade cover 2311.Described sun gear 2312 is crushed on two flanges of water tap inactive, and being connected by spline of sun gear 2312 and slip casting core pipe, sealing is by o type circle; Drilling rod and planetary wheel carrier fuse.
Its course of work is that power source comes autorotation disk to drive the drilling rod rotation, when described positive rotating vane sheet is just changeing, planetary gear 1 and motionless sun gear 2312 engagements, make planetary gear 2 2314 counter-rotatings after planetary gear 1 that is just changeing and planetary gear 2 2314 engagements, described gear ring blade cover 2311 counter-rotatings in described planetary gear 2 2314 and gear ring blade cover 2311 engagement backs, the also counter-rotating thereupon of counter-rotating blade 232 on the described gear ring blade cover 2311, whole cyclic train mechanism design is small and exquisite, and installation and removal are convenient.
The bidirectional guniting drilling bit that the utlity model has reversible rotation stirring function is not changing under original agitation pile stake machine structure and the method for operating condition, and realization stake machine drill head forward and backward is two-way to be crept into and stir; Pile-forming speed and pile quality have been improved, can guarantee the infiltration capacity of pile body cement paste, the slurry phenomenon can not occur emitting, can extensively apply in the consolidation process on soft foundation bases such as railway bed, highway, port construction, municipal engineering, industry and civilian construction.Can reach ground stabilization or improvement, improve bearing capacity of foundation soil, reduce settlement of foundation, and carry out slope reinforcement, purposes such as diaphragm wall and underground engineering support.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from above claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
