Description
Technical field
The utility model relates to a kind of measuring instrument, relates in particular to a kind of mining horizontal oblique angle measuring device, belongs to the surveying instrument technical field.
Background technology
In the underground coal mine recovery process, bolt support technology is used widely, and the anchor bolt construction relationship between quality is to the intensity of roadway support and the production safety of whole mine, and the measurement at anchor pole inclination angle is the important component part that detects the anchor bolt construction quality; The top, the base angle anchor pole all has certain angle with level in design discipline, and exposing only has the anchor pole head (100mm～300mm), the base angle anchor pole can be subjected to the influence of base plate when measuring; The wall out-of-flatness of drift angle anchor pole place, the anchor pole One's name is legion is when carrying out the anchor bolt construction quality testing, owing to not convenient causing of measuring position can't measure fast.
Present applicable anchor pole drift indicator has two classes: a class is made up of sensor, hang plate, readout instrument three parts, and complex structure involves great expense, the operation specialty, and can not be in underground work before not authenticating by gas safety; Another kind ofly form, need ruler to pave anchor pole place wall, because top, the wall out-of-flatness of anchor pole place, base angle and can't measure by semicircular protractor, ruler, index dial etc.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of mining anchor pole drift indicator, and is simple to operate, can measure the anchor pole inclination angle of measuring all places in the tunnel easily.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mining horizontal oblique angle measuring device comprises weight, fine rule, reading dial, magnetic tentacle, support bar, connecting rod, hollow cylinder and point of fixity; Reading dial is marked with angle numerical value, and the straight flange of reading dial is made of both sides 85 degree connecting lines; The magnetic tentacle is parallel with connecting rod, support bar is vertically welded between magnetic tentacle and the connecting rod, be fixed with the hollow cylinder that is set on the connecting rod on the straight flange of reading dial, the xsect of connecting rod is that circle and end are provided with point of fixity, and fixed point is in the home position of reading dial; One end of fine rule is connected with weight, and the other end is connected on the point of fixity; Reading dial is marked to 85 degree near a side angle number of degrees value of connecting rod, and opposite side angle numerical value mark is to 90 degree; The magnetic tentacle is that the angle bar magnetization forms.
The beneficial effects of the utility model are: simple in structure, volume is little, be easy to carry, cost is low; Adopt mechanical structure, safe and reliable when use the down-hole; Be applicable to the anchor pole measurement of dip angle and the convenient reading of all places.
