Abstract

The invention relates to a two-way reamer, belonging to the technical field of special tools for horizontal directional drilling crossing engineering. The two-way reamer consists of a hollow transmission shaft, a roller bit and a centralizer, wherein one end of the hollow transmission shaft is a joint, and the other end of the hollow transmission shaft is provided with connecting threads; a baffle is welded in a central hole of the hollow transmission shaft; an installation base is welded on an outer pipe wall of the hollow transmission shaft corresponding to the baffle; a positive roller and a negative roller are welded on the installation base; and a through hole communicated with water holes of the positive roller and the negative roller and the central hole of the hollow transmission shaft is arranged on the installation seat. Due to the positive roller and the negative roller, the two-way reamer is controlled by a primary drilling machine and a secondary drilling machine respectively; when the hole cannot be extended in a positive direction, the hole can be extended in a negative direction by a secondary roller group; the hole can be extended for several times in a section in which the hole is difficult to form, therefore, the problem that the drilling machine is clamped during the negative hole extension is avoided, the construction difficulty is reduced, and the working efficiency is improved.

Description

Two-way reamer
Technical field
The present invention relates to a kind of two-way reamer, belong to horizontal directional drill and pass through the special tool technical field that engineering is used.
Technical background
In horizontal directional drill engineering reaming construction stage lithosphere reaming process and since traverse distance long with rock strength big, the slush pump discharge capacity is limited, the part rock cut can't carry portal outside.The one, cutter teeth the wearing and tearing of the high strength of rock down operating efficiency descend, often reamer difficulty has been accomplished the reaming task of whole hole, will the rock reamer be withdrawed from replacing rock reamer when the ream operation drilling depth is slow.The 2nd, hole Nei Yan cuts accumulation, is prone to cause the reamer lock of tool drilling.When lock of tool drilling appearred in the tradition reamer, reamer did not have the ability of cutting in the other direction, and the rock reamer of will oppositely pulling back this moment, the reamer of pulling back are difficult problems in the rock reaming construction, the construction risk that simultaneous is bigger.
Application number a kind of bi-directional hydraulic structure that is used for reamer that has been 201010219825.4 disclosure of the Invention is provided with the tapping hole that is communicated with water hole, reamer body center in reamer body; At some radially water pipes of reamer body arranged outside and inclination water pipe; Radially water pipe and inclination water pipe are communicated with this application respectively and can improve the reamer drilling effect with tapping hole; Improve drilling efficiency, but can only carry out unidirectional creeping into yet, reamer does not have the ability of cutting in the other direction; If meet lock of tool drilling, will cause the situation of reamer " in a dilemma ".
Summary of the invention
The objective of the invention is does not have the ability of cutting in the other direction for the reamer that overcomes above-mentioned prior art existence; Be prone to cause the defective of reamer lock of tool drilling; Provide a kind of in the time can not carrying out the forward reaming, can use reverse gear wheel group to carry out the two-way reamer of reverse reaming.
Technical scheme provided by the invention is:
The present invention is made up of Hollow Transmission Shafts, rock bit, centralizer; Hollow Transmission Shafts one end is a joint; The other end is provided with connecting thread, in the centre bore of Hollow Transmission Shafts, is welded with baffle plate, and is welded with mount pad on the corresponding Hollow Transmission Shafts outer tube wall of baffle plate; On mount pad, be welded with forward gear wheel and reverse gear wheel, also have on the mount pad and forward gear wheel and the hydrophthalmia of reverse gear wheel and the through hole that the Hollow Transmission Shafts centre bore is communicated with.
Described centralizer comprises that two righting boards and the plate muscle between two righting boards constitute, and are provided with groove on the edge of righting board.
The present invention is designed with forward gear wheel and reverse gear wheel; Respectively by the control of two rigs of major-minor, when can not forward carrying out reaming, use secondary gear wheel group to carry out reverse reaming; Can carry out repeatedly reaming back and forth of front and back at the section that is difficult for pore-forming, thereby avoid the problem of reverse reaming bit freezing.In addition, adopt two bench drill machines to drive two-way reamer, can carry out repeatedly reaming back and forth of front and back, under the prerequisite of the quality that guarantees the one-level reaming, for the next stage reaming is laid a good foundation at the section that is difficult for pore-forming.Not only reduced difficulty of construction, reduced the risk of reamer bit freezing, and can shorten the engineering time.
Description of drawings
Fig. 1 is a schematic cross-section of the present invention.
Fig. 2 is a three-dimensional view of the present invention.
The specific embodiment
As shown in the figure; The present invention is made up of Hollow Transmission Shafts 1, rock bit, centralizer, and Hollow Transmission Shafts 1 one ends are joint 6, and the other end is provided with connecting thread 6; In the centre bore of Hollow Transmission Shafts 1, be welded with baffle plate 7, and be welded with mount pad 3 on baffle plate 7 corresponding Hollow Transmission Shafts 1 outer tube walls; On mount pad 3, be welded with forward gear wheel 2 and reverse gear wheel 4, also have on the mount pad 3 and forward gear wheel 2 and the hydrophthalmia 8 of reverse gear wheel 4 and the through hole 11 that Hollow Transmission Shafts 1 centre bore is communicated with.
Described centralizer comprises that two righting boards 5 and the plate muscle between two righting boards 59 constitute, and are provided with groove on the edge of righting board 5.
When carrying out reaming and creep into, the present invention is connected with two rigs of major-minor respectively with screw thread 10 through the joint 6 on the Hollow Transmission Shafts 1, forward gear wheel 2 is controlled by two rigs of major-minor with reverse gear wheel 4; Can do the axis circular motion around rolling element; Simultaneously, mud is through the centre bore of Hollow Transmission Shafts 1, the through hole 11 on the mount pad 3, by hydrophthalmia 8 ejections of forward gear wheel 2 and reverse gear wheel 4; Landwaste in the boring is carried in suspension, thereby realizes the purpose of two-way reaming.
