Description
Technical field
The utility model relates to revolving in building field and digs a rotary pile-digging machine tool expansion hole creating technology field, the end, is specifically related to one and can actuates formula boring drill.
Background technology
For improving the bearing capacity of ground, many grounds of building adopt pile foundation construction.Pile foundation is divided into preformed pile, castinplace pile according to construction method.Castinplace pile has hand excavated pile, drilled pile, impact holing stake according to one-tenth well format, revolves and dig stake etc.Revolve and dig stake with its construction safety, fast, the advantage such as precision is high, noise is little, be conducive to environmental protection, bearing capacity of single pile is high, easy construction is widely used in city construction engineering.Digging a bearing capacity of pile foundation to reach higher revolving, needing the area increasing stake end, domestic revolving and dig stake and all adopt mechanical spiral-digging pore at present, the drilling diameter of stake is unanimous between the higher and lower levels, can not change.How making to revolve and dig stake and reach the effect being similar to pitching pile by digging holes artificially, is revolve to dig the basic of a process modification.
Utility model content
In order to overcome, to revolve the drilling diameter digging stake unanimous between the higher and lower levels, unalterable deficiency, the utility model provides one can actuate formula boring drill, the bucket chassis that can actuate formula boring drill falls within and reaches at the bottom of the revolving and to dig of design elevation, utilize drilling rod, the deadweight that can actuate formula boring drill is aided with certain pressure, make both wings chain bar opened with certain angle, continuous rotary cutting soil layer or rock stratum, and after carrying brill by bucket chassis, the native slag cut or rock slag are cleared out outside hole, reach the object of revolving and digging enlarged opening on pile bottom, meet job requirements, guarantee construction safety.
In order to solve above-mentioned technical problem, the technical scheme that the utility model adopts is as follows:
One can actuate formula boring drill, comprises upper bracket, undersetting, bucket chassis, and upper bracket and fin are by bearing pinned connection, and undersetting and fagging are by bearing pinned connection, and fin and fagging, by bearing pinned connection, form both wings chain bar; Fin, fagging are distributed with and cut native gear piece, upper bracket is installed with drilling rod, drilling steel slip coordinates with in sliding sleeve, forms reaming bit; Sliding sleeve upper weld has gripper shoe, and lower weld has undersetting, and gripper shoe, undersetting are connected with reinforcement gusset respectively and between sliding sleeve outer wall.
Described undersetting comprises two pieces of junction plates be symmetrically welded in sliding sleeve, and junction plate is connected with fagging by bearing bearing pin.
Described sliding sleeve bottom is provided with end plate, and end plate edge has pin-and-hole.
The beneficial effects of the utility model are as follows:
The bucket chassis that the utility model can actuate formula boring drill falls within and reaches at the bottom of the revolving and to dig of design elevation, utilize drilling rod, the deadweight of formula boring drill can be actuated be aided with certain pressure, make both wings chain bar opened with certain angle, continuous rotary cutting soil layer or rock stratum, and after carrying brill by bucket chassis, the native slag cut or rock slag are cleared out outside hole, reach the object of revolving and digging enlarged opening on pile bottom, meet job requirements, guarantee construction safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, one can actuate formula boring drill, comprises upper bracket 1, undersetting 2, bucket chassis 16, upper bracket 1 is connected by bearing bearing pin 8 with fin 3, undersetting 2 is connected by bearing bearing pin 10 with fagging 4, and fin 3 is connected by bearing bearing pin 9 with fagging 4, forms both wings chain bar; Fin 3, fagging 4 are distributed with and cut native gear piece, upper bracket 1 is installed with drilling rod 7, drilling rod 7 is slidably matched with in sliding sleeve 11, forms reaming bit; Sliding sleeve 11 upper weld has gripper shoe 17, and lower weld has undersetting 2, and gripper shoe 17, undersetting 2 are respectively and be connected with between sliding sleeve 11 outer wall and strengthen gusset 12,13.
Undersetting 2 comprises two pieces of junction plates be symmetrically welded in sliding sleeve, and junction plate is connected with fagging by bearing bearing pin, and sliding sleeve 11 bottom is provided with end plate, and end plate edge has pin-and-hole 15.
When the utility model uses, first can actuate formula boring drill to complete according to the method described above, the bucket chassis that can actuate formula boring drill again falls within and reaches at the bottom of the revolving and to dig of design elevation, utilize drilling rod, the deadweight of formula boring drill can be actuated be aided with certain pressure, make both wings chain bar opened with certain angle, continuous rotary cutting soil layer or rock stratum, and after carrying brill by bucket chassis, the native slag cut or rock slag are cleared out outside hole, reach the object of revolving and digging enlarged opening on pile bottom, meet job requirements, guarantee construction safety.
