Abstract
The utility model discloses a high-precision directional drill, primarily comprising a revolution electrical machine, a drill rod, a drill point, a supporting and drawing oil cylinder, etc. The utility model is characterized in that a light source is fixed in the drill point by a dog screw, and a mark is stuck on the mirror face of the light source. The revolution electrical machine and a speed reducer are all fixedly connected with a beam via a bolt. The utility model has reasonable structure and skillful design, being applied to all kinds of pipes for straight line construction of non excavation. The utility model has the technical characteristics of exact directional control, reliable equipment operation, strong barrier eliminating ability, wide soil quality application, quick and convenient construction, small occupying field and long distance and degree supporting. The drill point of a guiding drill rod starts from a working well, drilling in a soil layer by a theodolite guiding direction. The utility model proceeds with checking yaw by means of the unbalanced soil pressure in the special structure of the leading edge of the drill point, the utility model makes the directional drill rod exactly arrive to the accepted well, and then hole expansion is done once in position according to the requirement of designed pipe diameter, accordingly the formation of the pipe is completed, and the utility model has generalization value.
Description
Technical field:
The utility model relates to the construction machinery that a kind of non-excavation lays guide's drilling rod, belongs to the construction machinery technical field.
Background technology:
At present, known directed boring is the position of determining drill bit by electromagnetic wave.But because electromagnetic generator and ground separation have one section soil layer, the uneven attitude on the uncertainty of soil layer medium and the face of land causes electromagnetic wave to be disturbed, and causes measure error bigger.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, and direction control is accurate high-precision fixed to brill.The technical scheme that its technical problem that solves the utility model adopts is, a kind of high-precision fixed to brill, mainly be by turning motor, drilling rod, drill bit, compositions such as oil cylinder are drawn on the top, its characteristics are: light source is fixed in the drill bit with the spline screw, mark is attached on the light source minute surface, drill bit and drilling rod are with being threaded, bearing is fixed on the support, drilling rod draws oil cylinder to be separately fixed at a crossbeam left side with crossbeam internally-powered axle with two tops that are threaded, right both sides, and piston rod is fixed on the back seat, strut also is fixed on the back seat, turning motor, reductor is all fixedlyed connected with crossbeam by bolt.Owing to adopt such scheme, be not difficult to draw and the utlity model has following beneficial effect, the utility model is rational in infrastructure, is skillfully constructed, be highly suitable for the non-excavation straight line construction of various pipes, have direction control accurately, equipment is reliable, and row's barrier ability is strong, it is wide to be suitable for soil property, it is quick and convenient to construct, and occupied ground is little, long technical characterictic apart from the degree jacking.The guide rod drill bit is from active well, creep at soil layer by the transit channeling direction, utilize the uneven soil pressure of drill bit tip special construction to rectify a deviation, directed drilling rod is accurately arrived accept well (maximum deviation 10MM), put in place by a reaming of design pipe diameter requirement then, thereby finish laying of pipeline, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is located at the schematic diagram of the mark on the light source minute surface for the utility model.
The specific embodiment:
Among the figure, these high-precision fixed light source 2 usefulness spline screws to brill are fixed in the drill bit 1, mark 8 is attached on light source 2 minute surfaces, drill bit 1 is threaded with drilling rod 7 usefulness, and bearing 12 usefulness screws are fixed on the support 11, and drilling rod 7 can move forward and backward in the through hole on the bearing 12, bearing 12 play the guiding role, drilling rod 7 and crossbeam 3 internally-powered axles are with being threaded transfer torque, and the power of line shaft be by turning motor 4 by big small belt pulley, belt passes to reductor 5.Two tops draw the shell of oil cylinder 6 to be separately fixed at crossbeam 3 and arranged on left and right sides.And piston rod is fixed on the back seat 10, owing to back seat 10 is connected with support 11 usefulness bolt, so piston rod and support 11 are fixed together.Strut 9 also is fixed by bolts on the back seat 10, promptly is to be fixed on the support 11.Turning motor 4, reductor 5 is all fixedlyed connected with crossbeam by bolt.Hydraulic oil enters Liang Ding and draws oil cylinder 6, drives crossbeam 3, drilling rod 7 and slides along the guide rail on the support 11 together, realizes moving forward and backward.
