Furthermore, the first pointer is kept vertical all the time under the action of the gravity of the pendant, and the first pointer is in transmission connection with the angle sensor through the damping rotating shaft.

Furthermore, the second pointer and the position far away from one end of the angle sensor are fixedly connected with the dial through a pin.

Furthermore, the straight line of the second pointer is parallel to the central axis of the probe tube.

Furthermore, the probe tube is of a telescopic structure.

Furthermore, the material of probe and instrument is the stainless steel, inlay explosion-proof glass cover on the observation face on the instrument.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses in, for making the contained angle between two pointers just equal to the angle of inclination of drilling, the event makes the straight line at second pointer place and the axis of exploring tube parallel, thereby reduce the conversion once more of contained angle, and first pointer remains throughout vertical under the action of gravity of pendant, when using the instrument to measure, first pointer keeps vertical under the effect of hanging the weight of falling, treat that it can form a definite contained angle between stable back and the second pointer, and first pointer passes through the damping pivot and is connected with the angle sensor transmission, event angle sensor passes through the electronic sensing technique, read the contained angle scale of two pointers on the calibrated scale, thereby measure the horizontal inclination of non-perpendicular or unevenness domatic stock, and then obtain the angle of drilling.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

measure tunnel stock angle instrument, including probe 1 and instrument 2, probe 1 is hollow structure, and be as an organic whole with the combination of instrument 2, instrument 2's inboard is equipped with calibrated scale 21, calibrated scale 21's left side is equipped with first pointer 22, calibrated scale 21's right side from the bottom up is equipped with second pointer 23 in proper order, angle sensor 24 and electron LCD screen 25, first pointer 22 rotates with angle sensor 24 to be connected, and first pointer 22 is close to the tip department of scale and is equipped with pendant 26, zero scale and holding position on the directional calibrated scale 21 of second pointer 23 are fixed, angle sensor 24's signal output part and the signal reception end electric connection who inlays the electron LCD screen 25 of locating on calibrated scale 21.

In order to enable the included angle between the two pointers to be equal to the inclined angle of the drilled hole, the straight line of the second pointer 23 is parallel to the central axis of the probe 1, so that the included angle is reduced to be converted again, the first pointer 22 is always kept vertical under the action of the gravity of the pendant 26, when an instrument is used for measurement, the first pointer 22 is kept vertical under the action of the gravity of the pendant 26, a determined included angle is formed between the first pointer 22 and the second pointer 23 after the first pointer is stabilized, the first pointer 22 is in transmission connection with the angle sensor 24 through the damping rotating shaft 27, so that the angle sensor 24 reads the included angle scales of the two pointers on the dial 21 through an electronic sensing technology, the horizontal inclined angle of the anchor rod on the non-vertical or uneven slope is measured, and the angle of the drilled hole is obtained.
