The equipment comprises a slurry pump station, a high-pressure rubber tube, a slurry injection connector, an ejecting-drilling rod, an inserted reamer, a pulling-drilling rod and a horizontal guide drilling machine, wherein the slurry pump station is arranged at one end of the horizontal directional crossing equipment; the high-pressure rubber tube is connected with the slurry pump station; the slurry injection connector is connected with the high-pressure rubber tube; the ejecting-drilling rod is connected with the slurry injection connector; the inserted reamer is connected with the ejecting-drilling rod; the pulling-drilling rod is connected with the inserted reamer; the horizontal guide drilling machine is arranged at the end part of the pulling-drilling rod; the inserted reamer comprises a reamer pipe column and an inserted blade gear hob in threaded connection with the reamer pipe column; a bearing core pack is arranged in the inserted blade gear hob; a tooth casing is sleeved with the outer part of the bearing core pack; the tooth casing and the bearing core pack are hermetically connected through a rubber ring soft seal and a hard seal of metal matched with a rubber ring. Through the adoption of the structure, the tooth casing and the bearing core pack are sealed well, so that slurry is prevented from entering the inner part of the bearing core pack, and the damage of the inserted blade gear hob is prevented.
Description
Technical field
The utility model relates to a kind of Horizontal directional through-passing equipment, relates in particular to a kind of Horizontal directional through-passing equipment of slurry injection.
Background technology
Horizontal directional through-passing technology has obvious superiority when the obstacles such as oil and gas pipes river crossing, lake, the main line of communication, railway terminal and important area.The general slurry injection technique that adopts in directional traversing construction at present, its technological principle is that rig is while driving drilling tool rotary to turn borehole enlargement by drawing back, slurry injection joint one end is connected rotation with drilling pipe, the other end is connected and does not rotate with high-pressure rubber pipe, now mud pumping plant by mud through high-pressure rubber pipe, to noting in joint and drilling pipe injection hole, to reach protection hole wall, clear hole and the object of rinsing drill bit, the work technological process that inserted reamer is executed: rig drives drilling rod to rotate back to and drags reamer reaming, one end is connected rotation with drilling rod, one end is connected with high-pressure rubber pipe, borehole enlargement by drawing back device, in drilling process, guide character is good, the flushing liquor horizonally projected jet of drilling tool, be conducive to protect hole wall, and return to drag in process and push, ward off flat hole wall, be conducive to pipe laying.Existing inserted reamer comprises reamer tubing string, the inserted tooth hob of screwed connection on reamer tubing string, described inserted tooth hob inside is provided with bearing core bag, the outside socket of described bearing core bag tooth shell, between described tooth shell and bearing core bag, by rubber ring soft seal, realize and being tightly connected, it is inner that mud easily enters bearing core bag, and inserted tooth hob is damaged.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of Horizontal directional through-passing equipment that prevents the slurry injection that inserted tooth hob damages is provided.
The utility model is to be achieved by the following technical programs:
A kind of Horizontal directional through-passing equipment of slurry injection, comprise the mud pumping plant that one end arranges, the high-pressure rubber pipe being connected with mud pumping plant, the slurry injection joint being connected with high-pressure rubber pipe, the push rod drilling rod being connected with slurry injection joint, the inserted reamer being connected with push rod drilling rod, the pull bar drilling rod being connected with inserted reamer and the horizontally-guided rig of being located at pull bar drill rod end, described inserted reamer comprises reamer tubing string, the inserted tooth hob of screwed connection on reamer tubing string, described inserted tooth hob inside is provided with bearing core bag, the outside socket of described bearing core bag tooth shell, between described tooth shell and bearing core bag, by rubber ring soft seal and the metal hard-sealing that coordinates with rubber ring, realize and being tightly connected.
The beneficial effects of the utility model are:
Owing to realizing and being tightly connected by rubber ring soft seal and the metal hard-sealing that coordinates with rubber ring between described tooth shell and bearing core bag, can be to carrying out good sealing between tooth shell and bearing core bag, prevent that mud from entering bearing core bag inner, prevent that inserted tooth hob from damaging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the main TV structure schematic diagram of the inserted reamer of the utility model.
Fig. 3 is the main TV structure schematic diagram of the utility model inserted tooth hob.
In figure: 1. mud pumping plant, 2. high-pressure rubber pipe, 3. slurry injection joint, 4. push rod drilling rod, 5. inserted reamer, 6. pull bar drilling rod, 7. horizontally-guided rig, 8. reamer tubing string, 9. bearing core bag, 10. tooth shell, 11. metal hard-sealings, 12. rubber ring soft seals.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises the mud pumping plant 1 that one end arranges, the high-pressure rubber pipe 2 being connected with mud pumping plant, the slurry injection joint 3 being connected with high-pressure rubber pipe, the push rod drilling rod 4 being connected with slurry injection joint, the inserted reamer 5 being connected with push rod drilling rod, the pull bar drilling rod 6 being connected with inserted reamer and the horizontally-guided rig 7 of being located at pull bar drill rod end, described inserted reamer comprises reamer tubing string 8, the inserted tooth hob of screwed connection on reamer tubing string, described inserted tooth hob inside is provided with bearing core bag 9, the outside socket of described bearing core bag tooth shell 10, between described tooth shell and bearing core bag, by rubber ring soft seal 12 and the metal hard-sealing 11 that coordinates with rubber ring, realize and being tightly connected.
Owing to realizing and being tightly connected by rubber ring soft seal and the metal hard-sealing that coordinates with rubber ring between described tooth shell and bearing core bag, can be to carrying out good sealing between tooth shell and bearing core bag, prevent that mud from entering bearing core bag inner, prevent that inserted tooth hob from damaging.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
