Abstract
The utility model provides a kind of mechanical coal mine roadway bore direction measuring instrument, and problem to be solved in the utility model is a kind of bore direction measuring instrument accurately carrying out azimuth determination under the premise of ensureing explosion-proof demand of design；It is characterized in that being fixed with rectangular patch litter on ring-band shape scale pallet buckles, rectangular patch litter, which is buckled, is fixed with lantern ring, and litter is inserted into lantern ring, and litter is provided at both ends with adjusting lift hook；Rectangular patch litter is provided with bearing below buckleing, and pointer is fixed on the bearing holder (housing, cover) of bearing, and one end of the pointer is provided with pendant line.The utility model has the advantages that purely mechanic instrument, without power supply and has explosion-proof performance；Operate access threshold it is low, ordinary labourer can skilled operation, it is easy for installation；Instrument is light, and it is high to give bearing accuracy.
Description
Technical field：
It is specifically a kind of mechanical the utility model is related to coal mine underground construction azimuth determination technical field of tools
Coal mine roadway bore direction measuring instrument.
Background technology：
Coal mine down-hole drilling can handle the major safety risks such as gas, fire, floods and accident, and azimuth is drilling construction
Indispensable basic parameter, the given accuracy in azimuth, ease for use are most important.Drilling construction is azimuthal given, can
The methods of point, electronic product are painted by technical staff's measuring and calculating to carry out.Technical staff a little gives azimuthal method to calculate to paint, and is boring
Easily there is the phenomenon that giving heavy workload, accuracy error in the intensive mine in hole；Electronic product gives azimuthal method, there is price
Costliness is not durable, must have the characteristics of explosion-proof performance.Therefore cheap machine that is durable, practical and convenient, need not having explosion-proof performance is developed
The azimuth that tool measuring instrument gives coal mine down-hole drilling construction is very necessary, very real.
Problem to be solved in the utility model is：Design one kind accurately carrying out orientation under the premise of ensureing explosion-proof demand
The bore direction measuring instrument of angular measurement.
Invention content
The purpose of this utility model is to provide a kind of mechanical coal mine roadway bore direction measuring instrument.
What the purpose of this utility model was realized in：It includes：Ring-band shape scale pallet, pointer, pendant line, is adjusted litter
Save suspension hook；Rectangular patch litter is fixed on ring-band shape scale pallet to buckle, rectangular patch litter, which is buckled, is fixed with lantern ring, in lantern ring
It is inserted into litter, litter is provided at both ends with adjusting lift hook；Rectangular patch litter is provided with bearing, the bearing holder (housing, cover) of bearing below buckleing
On be fixed with pointer, one end of the pointer is provided with pendant line.
The adjusting lift hook is cable, and the end set of cable has hook.
The litter is hollow cylinder structure.
The utility model has the advantages that being purely mechanic instrument, without power supply and has explosion-proof performance；It is low to operate access threshold,
Ordinary labourer can skilled operation, it is easy for installation；Instrument is light, and it is high to give bearing accuracy.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Embodiment 1
Referring to Fig. 1, it is fixed with rectangular patch litter on ring-band shape scale pallet 1 and buckles 2, rectangular patch litter, which is buckled, to be fixed with
Lantern ring 3, lantern ring is interior to be inserted into litter 4, and litter is provided at both ends with adjusting lift hook 5；Rectangular patch litter is provided with axis below buckleing
5 are held, pointer 7 is fixed on the bearing holder (housing, cover) 6 of bearing, one end of the pointer is provided with pendant line 8.
The adjusting lift hook is cable, and the end set of cable has hook.
The litter is hollow cylinder structure.
The application method of the utility model is as follows：Mechanical coal mine roadway bore direction measuring instrument, by adjustable suspension hook, cunning
Pole, scale pallet, pointer, pendant five kinds of components of line assemble.Top plate first in the chamber of drilling construction or tunnel, which gives, to be set
Azimuth device, is then hung on along datum line level on chamber or the top plate in tunnel by the indicated datum line of meter.By scale pallet
It is moved to by litter right over the drilling rod of drilling equipment, adjustment pointer angle is to reach the construction orientation of drilling design requirement
Angle, ajusting fuselage keeps the drilling rod of drilling equipment parallel with pendant line or overlaps, and can fix drilling equipment, manually give drilling construction
Azimuth terminate.
