Abstract
A direction-controllable pilot guide bit for a horizontal directional drilling pipe-laying drilling machine is a drilling tool for the horizontal directional drilling pipe-laying drilling machine, and comprises an outer casing, an inclined palm, an inclined palm seat and a rear drill pipe sub, wherein two ends of the outer casing are connected with the inclined palm seat and the rear drill pipe sub respectively; the inclined palm is fixed onto the inclined palm seat; and a magnetic signal emitting probe and a positioning key plug are arranged in the outer casing. The direction-controllable pilot guide bit is characterized in that spacing screw holes are formed on the outer casing; spacing grooves are formed on the cylindrical surface of the positioning key plug; a clamping block is arranged on one side surface of the positioning key plug; a clamping groove is formed on the magnetic signal emitting probe; and through the spacing grooves formed on the positioning key plug, the positioning key plug is fixed by a small jackscrew and a large jackscrew which are mounted on the spacing screw holes formed on the outer casing. As the positioning key plug is fixed by the small jackscrew and the large jackscrew through the spacing screw holes, the positioning key plug clamps the magnetic signal emitting probe to prevent the rotation of the magnetic signal emitting probe. Therefore, the position of the magnetic signal emitting probe is fixed, and deviation is avoided.
Description
Technical field
The utility model belongs to non-excavation and creeps into the pipe-laying machine field, is specifically related to a kind of horizontal orientation and creeps into pipe laying rig direction controllable type starter.
Background technology
Direction controllable type starter is that a kind of horizontal orientation creeps into pipe laying rig drilling tool, magnetic signal emission probe is housed in it, in drilling process, magnetic signal emission probe in the starter transmits, ground receiver receives signal, with the position and the track of definite bit body, thereby guide it on the track of expection, to creep into.Existing starter is directly launched magnetic signal probe and is placed in the starter body, utilize the stifled magnetic signal emission probe that blocks of positioning key, but, thereby cause the position instability of magnetic signal emission probe maybe deviation can occur not to the stifled issuable rotary stopper of positioning key.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of horizontal orientation to creep into the pipe laying rig with direction controllable type starter, makes its fast and accurate location of magnetic signal emission probe energy.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of horizontal orientation creeps into the pipe laying rig with direction controllable type starter, comprises shell body, the tiltedly palm, tiltedly palm seat and back tool joint.The two ends of shell body connect oblique palm seat and back tool joint respectively; Tiltedly the palm is fixed on the oblique palm seat, it is stifled to be provided with magnetic signal emission probe and positioning key in the shell body, it is characterized in that on described shell body, being provided with spacing screw, on the stifled face of cylinder of positioning key, be provided with stopper slot, the one side is provided with fixture block, magnetic signal emission probe is provided with draw-in groove, and stifled little jackscrew and the big jackscrew that is installed in the shell body upper limit screw by the stopper slot on it of positioning key fixed.
Compared with prior art, above-mentioned horizontal orientation creeps into pipe laying rig direction controllable type starter and utilizes little jackscrew and big jackscrew stationary positioned key to block up by spacing screw, prevent that by the stifled magnetic signal emission probe that blocks of positioning key it from rotating, guaranteed the stable of magnetic signal emission probe position and deviation do not occurred.
Description of drawings
Fig. 1 is the utility model sectional structure schematic diagram.
Fig. 2 is the decomposition sectional structure schematic diagram of Fig. 1.
Wherein: tool joint behind the 1-, 2-shell body, 3-tiltedly slap seat, 4-tiltedly slaps, the 5-positioning key is stifled, 6-plug, the little jackscrew of 7-, the big jackscrew of 8-, 9-spring, 10-spring plug screw, 11-sealing plug screw, 12-magnetic signal emission probe, 13-sealing ring, 14-inner chamber body, 15-stopper slot, 16-draw-in groove, 17-fixture block, the spacing screw of 18-
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See also accompanying drawing, horizontal orientation creeps into pipe laying rig direction controllable type starter, comprise shell body 2, tiltedly palm seat 3, tiltedly slap 4 and back tool joint 1, the two ends of shell body 2 connect oblique palm seat 3, reach back tool joint 1 with taper thread respectively, form the starter body, tiltedly slap 4 and be fixed on the oblique palm seat 3.Be processed with spacing screw 18 on the shell body 2, be provided with inner chamber body 14 in it, magnetic signal emission probe 12 is installed in the cavity body 14 of shell body 2, the front end of described magnetic signal emission probe 12 is provided with stifled 5, the plug 6 of positioning key, be processed with stopper slot 15 on the face of cylinder of positioning key stifled 5, the one side is provided with fixture block 17; The rear end of magnetic signal emission probe 12 is provided with spring plug screw 10; Be equipped with sealing ring 13 on plug 6 and the spring plug screw 10, play sealing and damping.The front end of magnetic signal emission probe 12 offers draw-in groove 16, fixture block 17 on the key that is positioned stifled 5 blocks rapid location, positioning key stifled 5 is fastening by little jackscrew 7 and big jackscrew 8 that the stopper slot on it 15 is installed in the spacing screw 18, plays the effect that prevents 12 rotations of magnetic signal emission probe.Described magnetic signal emission probe 12 rear ends are connected by spring 9 with an end of spring plug screw 10, and the other end of spring plug screw 10 is used seal with screwed joint with sealing plug screw 11.Magnetic signal emission probe 12 was axially fixed by shell body 2 and back tool joint 1, being connected of oblique palm seat 3.
The signal emission groove that the signal of magnetic signal emission probe 12 emissions passes on the shell body 2 is transmitted into ground receiver, and the control of realization level is to creeping into.
