It is reformed transform by current mine suspension compass and is characterized in that: the laser is additionally arranged on a lifting ring of the mine suspension compass, the direction of a light beam is parallel to the connecting line of 0-degree and 180-degree depiction centers of a compass face, the gradienter is additionally arranged in a compass cavity, the light beam can replace a lifting rope during use, the light beam is projected at a target position, an azimuth angle is read, and the compass face is erected to read a gradient numerical value.

Description

Laser compass

(1) technical field

The present invention is a kind of laser compass, relates to a kind of laser compass that uses in mine surveying specifically, belongs to the surveying instrument class.

(2) background technology

Present mine hangs box compass, by the hanging wire orientation, operates loaded down with trivial detailsly, all relies on total powerstation also unrealistic, is in the reality problem to be solved to be arranged.

(3) summary of the invention

Purpose of the present invention, be make easy and simple to handle reliable, to remedy the deficiencies in the prior art.

Technical scheme of the present invention is such: it hangs the box compass transformation of the way by existing mine and forms, feature is: hang on the suspension ring of box compass in the mine or pass through connecting link, be fixed with laser instrument, laser instrument can send a visible light beam, the line at the axial line of light beam and 0 degree and 180 degree portrayal centers is parallel to each other, the direction of light beam is pointed to working direction, adds gradient device in the compass chamber.

In the such scheme, the top of suspension ring claims suspension rod, laser instrument can be fixed on the suspension rod by connecting link, connecting link can only connect a suspension rod, the connecting link length of this moment, slightly equal the length of laser instrument, connecting link also can connect two suspension rods, fixes a laser instrument, or fixes two laser instruments dorsad, check the position angle to make things convenient for back, connecting link and suspension rod be integrally casting certainly, is to prevent that laser instrument from damaging the inconvenience that causes, can the arc place below suspension ring to set up a laser instrument more standby to do, this moment, the outer arc limit of suspension ring below can be changed into straight flange with convenient fixing, can certainly only adopt one of these three kinds of modes.

In the such scheme, the fixed form of laser instrument is fixed with screw but the groove shape is inserted, on the connecting link, suspension ring below give and leave the screw perforation that has screw, on the housing of laser instrument, give and leave the screw perforation.

In the such scheme, the material of laser instrument is selected non-ferrous metal for use, alloy or with macromolecular material, two suspension rods are than existing lengthening, the segmental arc of suspension ring below to the distance at compass center increases relatively, not influencing needle with laser instrument is as the criterion, the power supply of laser instrument adopts built-in button cell, described laser instrument is meant can launch the device that redness or visible light beam and light beam indiffusion can present hot spot, this light beam abbreviates laser beam down as, described laser instrument is its electronic component, switch, power supply, general name when housing etc. become one, the toy laser pen basically identical of its structure and market.

In the such scheme, 90 degree and 270 degree both sides add two arcs or semicircular pipe level in the box compass chamber, bubble, micro-mercury solution, liquid are arranged in the level tube chamber, but its liquid ether or alcohol etc., the size of the size of bubble, mercury solution liquid point, be advisable conveniently seeing clearly with reading, on level tube or card, set up the portrayal and the number of degrees accordingly, the gradient 0 portrayal is on the lines of card position angle 90 degree and 270 degree, till both sides were respectively spent to 90, the center number of degrees of minute bubbles and mercury solution liquid point were consistent with the horizontal angle of laser beam and the earth all the time; Read the number of degrees of mercury solution liquid point and the number of degrees of minute bubbles, relatively to reduce misreading of the gradient, certainly only establish a level tube arbitrarily mutually, this level is consistent with common pipe level structure, and its material is glass or transparent macromolecular material; On arc or semicircular pipe level, the level tube or portrayal of setting up on the card and number of degrees general name gradient device.

The present invention compared with prior art advantage is: easy and simple to handle.
