Abstract

The utility model belongs to the down-hole gradient and distance-measuring device technical field, is specifically related to a kind of underworkings stringcourse measuring instrument.The utility model mainly solves the existing measurement on underworkings and has that measuring accuracy is low, error is large, need many people compounding practice when measuring, occupied ground is large, Measuring Time is long and affect the technical matters of normal production work of team's group in tunnel.The technical solution adopted in the utility model is: a kind of underworkings stringcourse measuring instrument, comprises tape measure, level meter, tape measure cartridge, laser range finder, WidFin bolt and telescoping handle.The utility model has that measuring accuracy is high, error is little, simple to operate, not occupied ground, to measure efficiency low and do not affect the advantage of normal production work of team's group in tunnel.

Description

A kind of underworkings stringcourse measuring instrument
Technical field
The utility model belongs to the down-hole gradient and distance-measuring device technical field, is specifically related to a kind of underworkings stringcourse measuring instrument.
Background technology
China's modernization large-scale mine digging laneway mechanization degree is high, and driving speed is fast, and the therefore measurement such as laneway molding, slope control, checking and accepting amount increase thereupon.Current underground tunneling roadway is measured and is adopted instrument or the total powerstations such as tilt gauge, tape measure and horizontal tube more, when using the instruments such as tilt gauge, tape measure and horizontal tube to measure, there is the technical matters that measuring accuracy is low and error is large.Use during total station survey and then need many people cooperation, there is the technical matters of the normal production work that occupied ground is large, Measuring Time long and affect team's group in tunnel.
Summary of the invention
The purpose of this utility model be solve that the existing measurement on underworkings exists that measuring accuracy is low, error is large, need many people compounding practice when measuring, occupied ground is large, Measuring Time is long and affect the technical matters of normal production work of team's group in tunnel, provides a kind of underworkings stringcourse measuring instrument.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of underworkings stringcourse measuring instrument, comprise tape measure, level meter, tape measure cartridge, laser range finder, WidFin bolt and telescoping handle, the middle part of described laser range finder is provided with rectangular through holes, the rear side of laser range finder is provided with cartridge engaging lug and is positioned at the side of rectangular through holes, tape measure cartridge is located in the rectangular through holes of laser range finder, tape measure to be located in tape measure cartridge and to make the chi hook of tape measure and tape be positioned at after laser range finder, level meter is located at the middle part of laser range finder end face, telescoping handle is located at the middle part of laser range finder bottom surface, tape measure cartridge is contained in the rectangular through holes on laser range finder by the engaging lug of WidFin screw bolt passes cartridge engaging lug and tape measure cartridge.
Compared with background technology, the utility model has the following advantages:
1) laser range finder and level meter combine and ensure that the precision of instrument level and distance in the measurements, and other most parameters directly draws by these two underlying parameters;
2) can the laneway laser gradient be measured rapidly or mark gradeline;
3) underworkings stringcourse measuring instrument is effectively combined by laser range finder, steel tape, level meter, Level tune and pull bar, and the multiple individual operations before making can complete in single job.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of underworkings stringcourse measuring instrument in the present embodiment, comprise tape measure 1, level meter 2, tape measure cartridge 3, laser range finder 4, WidFin bolt 7 and telescoping handle 5, the middle part of described laser range finder 4 is provided with rectangular through holes 6, the rear side of laser range finder 4 is provided with cartridge engaging lug 8 and is positioned at the side of rectangular through holes 6, tape measure cartridge 3 is located in the rectangular through holes 6 of laser range finder 4, tape measure 1 to be located in tape measure cartridge 3 and to make the chi hook of tape measure 1 and tape be positioned at after laser range finder 4, level meter 2 is located at the middle part of laser range finder 4 end face, telescoping handle 5 is located at the middle part of laser range finder 4 bottom surface, tape measure cartridge 3 is contained in the rectangular through holes 6 on laser range finder 4 through the engaging lug of cartridge engaging lug 8 and tape measure cartridge 3 by WidFin bolt 7 successively.
If steel tape is arranged on laser range finder internal main and is easy to carry for volume is little by this instrument, also steel tape can be arranged on laser range finder top or detachable.
The course of work of the present utility model is:
1) by telescoping handle 5 or pull-out tape measure 1, underworkings stringcourse measuring instrument is hung over top on the net, and allow laneway laser impinge upon in the tape of tape measure 1;
2) laser range finder is adjusted to level, impinges upon the point of helping in lane at laser and make marks, and record steel ruler end and the distance value shining steel ruler position to laneway laser;
3) utilize flexible rotatable the instrument of steel tape, impinge upon another point of helping in lane at laser and make marks, 2 lines are level;
4) hang instrument to another mark, method is the same, and laneway laser is beaten on steel ruler, and level-off makes marks in laser Suo Zhao lane side, and records steel ruler distance value;
5) horizontal range value and No. 2 steel rulers are marked apart from value differences by lane institute of side, laneway laser actual grade is calculated by trigonometric function difference, also can according to the actual fixed any gradient stringcourse of produced on-site, check institute dig tunnel and whether meet design grade and laneway molding requirement.
