Description
Technical field
The utility model relates to the extension of non-coal mine tunnelling and route type mining construction midline, stringcourse, is stringcourse extension meter in a kind of portable laser specifically.
Background technology
At present, the method and the instrument of center line, stringcourse demarcation and extension are a lot of in mine working driving and the route type mining construction, current sophisticated equipment surveying instrument such as transit, spirit-leveling instrument, director etc. all are with laser and are equipped with corresponding tripod, and its volume is big, quality is heavy, carry inconvenience, cost an arm and a leg, complicated operation.It is very inconvenient to extend center line, stringcourse in construction, and center line, stringcourse are often destroyed, need demarcate once more.Utilize sophisticated equipment in the market to extend, demarcate, remove and cost an arm and a leg, carry inconvenience, also need many people to cooperate, can't demarcate at any time, influence the ordinary production tissue, can not guarantee construction quality and safety.
The utility model content
Technical problem to be solved in the utility model be at center line, the stringcourse that use in mine in the market extend the costing an arm and a leg of instrument, all be with tripod, carry inconvenience, complicated operation, can not be immediately following situations such as construction operations, provide a kind of easy to carry, simple to operate, can be immediately following stringcourse extension meter in the portable laser of the scope of operation.
The utility model adopts following technical proposals to solve its technical matters:
The stringcourse extension meter comprises housing in a kind of portable laser, and its inside is divided into dominant control case, power supply box two parts with dividing plate, and power supply box is provided with the case lid that can slip off;
Laser instrument is made up of steel body skeleton, laser pen two parts, adopts red semiconductor laser, is mounted in the dominant control case;
Horizontal controller is made up of steel body skeleton, leveling bubble two parts;
The stringcourse datum strip is embedded in housing one side, is in same level with laser instrument laser nib;
Gauge tap is loaded in the dominant control case, and an end is connected with power supply by lead, and an end is connected with laser instrument by lead;
Electrical source of power is communicated with laser instrument, gauge tap by lead.
Described gauge tap adopts the mini button switch.
Described electrical source of power adopts No. 5 batteries, is installed in the battery case.
Described leveling bubble adopts the accurate leveling bubble of tubulose.
The utility model far firing range, precision height, easy to carry have been broken the situation that middle stringcourse extension meter must have supporting tripod " binding " work, need not to carry heavy tripod operation, can finish middle stringcourse extension and demarcate; Volume is little, light weight, easy to carry, and size is 140 * 25 * 45mm only, and is cheap, simple to operate, and continuous working need not charging in 48 hours, can be loaded on the working cloth pocket, take conveniently, and the precision height, can satisfy the production needs of down-hole fully; Simple to operate, broken to have only and measured the situation that the professional just can, could demarcate center line, extend stringcourse, non-measuring technique personnel such as mining specialty are slightly through measuring professional's guidance or carefully, conscientiously reading instructions and can operate, realize that the middle stringcourse in the mining process extends and demarcation, has enlarged operative technique troop; It is short to take the production operation time during operation, and front and back were less than three minutes, and are very little to the organization of production influence, help improving the pure production operation time, improve labor productivity; Can closely follow the digging operation face, be convenient to instruct in-situ production management, can check tunneling direction at any time, demarcate the digging center line, check the construction base plate at any time, extend stringcourse; Avoid and reduced that tunnel, route train off and the bad economic loss that causes of base plate control, control tunnelling, drift stoping quality have been brought into play very big effect, can satisfy the safety in production actual needs, realized optimal economic benefitization.

Embodiment
Stringcourse extension meter in a kind of portable laser comprises: laser instrument 1, horizontal controller 2, stringcourse datum strip 3, gauge tap 4, electrical source of power 5 and housing 6.Laser instrument 1 is the laser beam emitting device that middle stringcourse extends, and is made up of steel body skeleton 7, laser pen 8 two parts, adopts red semiconductor laser, is mounted in the dominant control case 9.Horizontal controller 2 is the horizontal direction control instrument of middle stringcourse extension meter, form by steel body skeleton 7, leveling bubble 10 2 parts, adopt the accurate leveling bubble of tubulose, when bubble occupy the centre position, whole laser beams is in horizontality, the horizontal stringcourse of available laser calibration this moment position.Stringcourse datum strip 3 is the stringcourse aligning parts of middle stringcourse extension meter, adopts plastic strip, is embedded in steel body 6 one sides, is positioned at same level with laser instrument laser pen 8 nibs.Gauge tap 4 is the power control switch of laser instrument, adopts the mini button switch, is mounted in the dominant control case 9, and an end is connected with power supply 5 by lead 11, and an end is connected with laser instrument 1 by lead 11.Electrical source of power 5 is the propulsion system of middle stringcourse extension meter, continues power supply power for Laser emission provides, and adopts No. 5 battery, is installed in the battery case 12, with spring 13 chuckings, is communicated with laser instrument 1, gauge tap 4 by lead 11.Housing 6 is the steel shell of middle stringcourse extension meter, size 140 * 25X45mm, be used to install and fix laser instrument 1, horizontal controller 2, stringcourse datum strip 3, gauge tap 4, electrical source of power 5, adopt the plastic-steel material, form by dominant control case 9, power supply box 12 2 parts; Separate with plastic-steel dividing plate 14 between dominant control case 9, power supply box 12 2 parts, Φ 10 wire guides 15 are reserved at plastic-steel dividing plate 14 middle parts; Power supply case lid 16 can slip off.
