Abstract
The utility model discloses an antimagnetic and explosion-proof clearance gauge comprising a plurality of strip pieces with different thickness and made of brass, two casings matched with the shape of the strip piece and made of stainless steel, fixed bolts and screw nuts; the two ends of the plurality of strip pieces and the two casings are round angles; the plurality of strip pieces and the two casings are arranged in an overlapping way; the two casings are respectively positioned at the outside of the plurality of overlapped strip pieces; one ends of the plurality of strip pieces and the two casings are provided with through holes; the fixed bolts are positioned in the through holes; and the screw nuts are screwed on the bolts and lead the plurality of strip pieces and the two casings to be capable of rotating with the bolts as the axial center. In order to be convenient for the strip pieces to be stuffed into the clearance during measuring the clearance, the round angles of the free ends of the strip pieces are smaller than that of the fixed ends thereof. During overhaul operation, the clearance gauge can be used for conveniently measuring the clearances between stators and rotators of magnetoelectric machines or of various combustion turbines in flammable and explosive fields, thus improving the overhaul efficiency; and the operation is safe and convenient, thus ensuring the safety of the overhaul operation.
Description
Technical field
The utility model relates to the clearance measurement instrument, relates in particular to a kind of diamagnetic explosion-proof feeler gauge.
Background technology
The clearance measurement instrument is widely used in fields such as motor, gas turbine maintenance, is used to measure gap between the rotor of all kinds of motors.The clearance measurement instrument mainly contains feeler gauge, and it mainly is made up of the feeler leaf of some different-thickness made from iron plate; But at all kinds of magnetoes, when overhauling as the generator pilot exciter, because this exciter is a permanent magnet, when adopting common feeler gauge to measure, feeler leaf is held by magnet, can't measure the rotor gap, has had a strong impact on overhaul efficiency; And in some gas turbine,, belong to damp operation occasion owing to use blast furnace gas as combustion medium, and when high gas concentration operation, use common feeler gauge measurement clearance not meet security regulations, cause all kinds of security incidents easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of diamagnetic explosion-proof feeler gauge, utilize this feeler gauge when upkeep operation, to overcome above-mentioned defective, can be convenient for measuring all kinds of magnetoes or the gap between all kinds of gas turbine rotors in inflammable and explosive place, improved overhaul efficiency, and handling safety, convenience have been guaranteed the safety of upkeep operation.
For solving the problems of the technologies described above, the diamagnetic explosion-proof feeler gauge of the utility model comprises the strip sheet of some different-thickness of being made by brass, article two, with shell and the set bolt and the nut made by stainless steel of described strip sheet form fit, the two ends of described some strip sheets and two shells are fillet, described some strip sheets and two overlapping settings of shell, described two shells lay respectively at the outside of overlapping described some strip sheets, described some strip sheets and two shell one ends have through hole, described set bolt is positioned at described through hole, and described nut is twisted on described bolt and made described some strip sheets and two shells can bolt be the axle center rotation.
Strip sheet is filled in the gap during for ease of clearance measurement, and the free-ended fillet of above-mentioned some strip sheets is less than the fillet of stiff end.
Because the diamagnetic explosion-proof feeler gauge of the utility model has adopted technique scheme, promptly adopt brass to make the strip sheet of some different-thickness as clearance gauge, some strip sheets outside is the shell of being made by stainless steel, the two ends of some strip sheets and shell are that a fillet and an end pass through bolt, and making some strip sheets can bolt be the axle center rotation; Use this feeler gauge when upkeep operation, can be convenient for measuring all kinds of magnetoes or in inflammable and explosive place the gap between all kinds of gas turbine rotors, improved overhaul efficiency, and handling safety, convenience, guaranteed the safety of upkeep operation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the diamagnetic explosion-proof feeler gauge of the utility model when deployed condition.
Embodiment
As shown in Figure 1, the diamagnetic explosion-proof feeler gauge of the utility model comprises the strip sheet 1 of some different-thickness of being made by brass, article two, with shell 2 and the set bolt 3 and the nut made by stainless steel of described strip sheet 1 form fit, the two ends of described some strip sheets 1 and two shells 2 are fillet, described some strip sheets 1 and two shell 2 overlapping settings, described two shells 2 lay respectively at the outside of overlapping described some strip sheets 1, described some strip sheets 1 and two shell 2 one ends have through hole, described set bolt 3 is positioned at described through hole, and described nut is twisted on described bolt 3 and made described some strip sheets 1 and two shells 2 can bolt 3 be the axle center rotation.
The diamagnetic explosion-proof feeler gauge of the utility model adopts brass to make the strip sheet of some different-thickness as clearance gauge, some strip sheets outside is the shell of being made by stainless steel, the two ends of some strip sheets and shell are that a fillet and an end pass through bolt, and making some strip sheets can bolt be the axle center rotation; Use this feeler gauge when upkeep operation, can not produce spark with other metal frictions, and be not subjected to magnetic interference, can be convenient for measuring all kinds of magnetoes or the gap between all kinds of gas turbine rotors in inflammable and explosive place, improved overhaul efficiency, and handling safety, convenience have been guaranteed the safety of upkeep operation.
When using this feeler gauge measurement clearance, before measurement, at first estimate the measured gap size, select the strip sheet of different-thickness for use, insert measured gap,, note strip sheet thickness, be the measured gap size according to tightness increase and decrease strip sheet thickness.If measured gap is bigger, the strip sheet of different-thickness can be superimposed, insert measured gap and measure.When noting using, should wipe clear strip sheet and tested surface.Situations such as strip sheet wearing and tearing, crimping taking place, should in time change, prevents the impurity effect measurement result.
Claims (2)
1, a kind of diamagnetic explosion-proof feeler gauge, it is characterized in that: this feeler gauge comprises the strip sheet of some different-thickness of being made by brass, article two, with shell and the set bolt and the nut made by stainless steel of described strip sheet form fit, the two ends of described some strip sheets and two shells are fillet, described some strip sheets and two overlapping settings of shell, described two shells lay respectively at the outside of overlapping described some strip sheets, described some strip sheets and two shell one ends have through hole, described set bolt is positioned at described through hole, and described nut is twisted on described bolt and made described some strip sheets and two shells can bolt be the axle center rotation.
