A bearing plate (13) is fixed on four upright posts of the outer stander.

Description

The vertical horizontal directional drilling machine of tape guide wheel

Technical field

The utility model relates to a kind of directed drilling equipment, relates in particular to a kind of vertical horizontal directional drilling machine of tape guide wheel.

Background technology

Along with the increasing of country to environmental improvement and urban infrastructure dynamics of investment, China's urban duct, cable laying work amount sharply increase in recent years.Traditional method of laying the line of past mainly adopts is from the ground excavation, the loss that the destruction of urban environment is caused usually be the channelling cost 3-5 doubly, become the bottleneck of restriction urban infrastructure.Develop a kind of non-excavation recently and laid the underground utilities technology, it mainly is the steerable drilling trenchless technology, but, horizontal directional drilling machine is the key equipment of non-excavating construction in this technology, present horizontal directional drilling machine is bigger for laying diameter, and the rigid conduit that the degree of depth is darker is owing to be subjected to the restriction of radius of curvature, pipe ends needs very long changeover portion, and can not possess this condition usually in municipal construction.As active well being dug to such an extent that too greatly also will directly have influence on excavate costs, and general this non-digging type directional drilling machine cost all reaches four, 500,000, both invested excessively, and use cost is also high.And exist the not so good location of some geological conditions, and front drill bit, drilling rod one mistake, just there is earth the back, and stone or cobble fall down, and the pipeline that influence need be laid returns and technical problem such as drags.

The utility model content

The purpose of this utility model is to provide a kind of cost low for overcoming the deficiencies in the prior art; use cost is low; the active well area can be effectively reduced and drilling channel can be effectively protected; help the vertical horizontal directional drilling machine that pipeline returns the tape guide wheel that drags; concrete technical scheme is: the vertical horizontal directional drilling machine of tape guide wheel is by motor; the gearbox of band gear lever; drilling rod; drill bit; the water seal cucurbit; compositions such as horizontal propeller; pass through connecting hole in the outer frame; thread connector is connected with an interior framework; interior framework can be by on thread connector and the connecting hole; under adjust the position; motor; gearbox is fixed on the interior framework; motor by gearbox with the drive bevel gear of transmission of power to the transmission case; drive bevel gear drives driven wheel of differential and rotates; driven wheel of differential drive center is that the drive socket of square hole rotates; send power to the pushing ram of band endoporus; the drilling rod and the drill bit of pushing ram one end connecting band dismounting mouth, the other end is connected with the water seal cucurbit.The other end of water seal cucurbit links to each other with a horizontal propeller, is socketed with a directive wheel on the drilling rod, the affixed water tank in outer frame upper end, and the delivery port of water tank links to each other by water pipe with the drilling rod water inlet pipe, is fixed with bearing plate on four columns of outer frame.

Said directive wheel be one with drilling rod dismounting mouthful corresponding two ribs of size and outer cylinder composition, there is mouth at the rib center, is stuck in the dismounting mouth, the upper and lower thread connection hole that is provided with of rib, by thread connector it is fixed in drilling rod, outer cylinder is affixed by thread connector and rib.

Said directive wheel also can be the U type fixture block that a band is placed in drilling rod dismounting mouth, forms with outer cylinder, is embedded with a voussoir in the breach of fixture block and outer cylinder.

For ease of can easily the pipe that lays being towed back to after drilling through, can set up one time and drag device.

Dragging device for said time is the pipe of a center band through hole, and the middle part of pipe is provided with reverse drill lip, and its big end is provided with a circular Supporting ring, and microcephaly's direction of pipe is provided with external sealing plug, and the other end connects a drag hook by plug.

Said horizontal propeller is fluid pressure type or electric screw formula.

For ease of changing drilling rod, can on the frame that is positioned at pushing ram one side, set up an operation panel.

When using the vertical horizontal directional drilling machine of the utility model, at first at selected street or the building both sides excacation well that needs boring, four bearing plates of vertical horizontal directional drilling machine are set level, filled up, and the size of adjusting inside and outside frame is started rig to the degree of depth that needs to bore, add drilling rod and directive wheel after being drilled into certain-length, until get into till the active well of opposite, take off drill bit then, set up back and drag device, and connect the pipeline that need lay, slowly pipeline is towed back to then and got final product.

From the technical solution of the utility model as can be seen,, and adopted vertical layout and set up directive wheel, because directive wheel rotates with drilling rod, both played orientation, the effect that can cause the rotation extruding to stablize hole wall again because the utility model is simple in structure.Both can reduce excavation area effectively, and also can effectively protect the pipeline after drilling through, cost is low, and operating cost is low, and handled easily has reached goal of the invention of the present utility model fully.
