Description
Technical field
The utility model is related to soil bore enlarging device more particularly to the soil bore enlarging devices of reducing.
Background technology
In the work progress of directional drilling crossing soil layer project, reamer is important drilling tool, but conventional reaming work at present
In skill, most of reamers are plank frame, and reamer size fixes, and each reamer can only expand wellbore to specific accordingly
Size, cannot be arbitrarily sized according to the variation on stratum or the combination of drilling tool, and constructs for heavy caliber crossing pipeline, needs
Reamer quantity it is more, cause construction transportation cost high.Based on the above reason, the soil bore enlarging device of this utility model reducing,
Save project cost, in solution project due to the use of multiple reamers generate it is of high cost, fragile, maintenance is not in place etc. asks
Topic.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of knot in view of the deficiency of the prior art
Structure is simple, replaces the soil bore enlarging device of reducing that is convenient, improving construction efficiency.
Technical solution used by the utility model is：A kind of soil bore enlarging device of reducing, it is characterised in that：Including master
Axis and retainer plate are distinguished intrinsic first connection ring and the second connection ring at the both ends of main shaft, are equipped in the lower end of the second connection ring
Adjuster, the adjuster are socketed on main shaft, and the circumferential direction between retainer plate and the first connection ring is hinged with multiple short side muscle
Plate, the circumferential direction between the second connection ring and retainer plate are hinged with multiple long side gussets, divide on short side gusset and long side gusset
Not She You cutter head, pass through replace different-diameter retainer plate and different length adjuster different-diameter reaming.
According to the above technical scheme, on main shaft location nut is configured with positioned at one end of adjuster.
According to the above technical scheme, multiple hinge holes are circumferentially in the first connection ring, for hinged with short side gusset.
According to the above technical scheme, multiple hinge holes are circumferentially provided in the second connection ring, for hinged with long side gusset.
According to the above technical scheme, it is circumferentially with multiple be respectively used to and short side gusset and long side gusset in the inner ring of adjuster
The hinge hole being hinged.
According to the above technical scheme, the adjuster is the cylindrical shape of both ends open.
Having the beneficial effect that acquired by the utility model：
1, the utility model is by replacing various sizes of retainer plate and adjuster, by changing long gusset and short rib
Opening angle and the diameter for adjusting retainer plate carry out whole reducing, can meet the reamer reducing of arbitrary dimension, reach general
Purpose, realize that single reamer replaces the reamer of all sizes in conventional construction, save project cost, it is strong to reduce labour
Degree；
2, simple in structure, easy to use, processing and fabricating requires low；
3, horizontal directional drill reaming service efficiency is improved, it is easy to utilize.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figs. 1-7, a kind of soil bore enlarging device of reducing, including main shaft 1 and retainer plate 4 are present embodiments provided,
Distinguish intrinsic first connection ring, 11 and second connection ring 9 at the both ends of main shaft 1, adjuster is equipped in the lower end of the second connection ring 9
6.The adjuster 6 is socketed on main shaft 1, and the circumferential direction between retainer plate 4 and the first connection ring 9 is hinged with multiple short side gussets
10, the circumferential direction between the second connection ring 9 and retainer plate 4 is hinged with multiple long side gussets 5, in short side gusset 10 and long side gusset
Cutter head 3 is respectively equipped on 5.It is equipped with screw thread 8 positioned at one end of adjuster on main shaft, location nut 7 is configured at screw thread 8,
Fixed reamer will not move.According to the opening angle of short side gusset 10 and long side gusset 5,4 He of other sizes retainer plate is replaced
Adjuster 6 achievees the purpose that reamer reducing.
In the present embodiment, multiple hinge holes are circumferentially in the first connection ring 11, for hinged with short side gusset 10.
Second connection ring 9 is circumferentially provided with multiple hinge holes, for hinged with long side gusset 5.It is circumferentially in the inner ring of adjuster 6
Multiple hinge holes for being respectively used to be hinged with short side gusset 10 and long side gusset 5.
The utility model can determine the size of retainer plate 4 and adjuster 6, scene system according to horizontal directional drill wellbore size
Facilitate, no precise part, the use of material is round steel and steel plate, easily draws materials, can be good at meeting adding under wild environment
Work demand.
During Directional Drilling for Pipeline Crossing, final counter bore diameter is 1.3~1.5 times of crossing pipeline diameter, according to
The Pipeline Crossing Program of 1016mm calculates, and needs 5~6 grades of reaming series, and 6 kinds of various sizes of reamers are at least used in construction, but
The soil bore enlarging device of the utility model adjustable dimension need to only use 1 reamer and auxiliary auxiliary facility (retainer plate 4 and tune
Section device 6) can complete all ranks reaming work, construction cost greatly reduces.After the reamer, hence it is evident that drop
Low working strength, improves work efficiency.
