Abstract
The invention relates to a gap detecting device, in particular to a gap detecting device with a concealed contracting brake. The invention mainly solves the technical problems that a clearance gauge has small detecting contact area, and is difficult to adjust. The technical scheme of the invention is that the gap detecting device with a concealed contracting brake comprises a toothed bar press valve, a toothed bar and gear driving mechanism and clamps, wherein the toothed bar and gear driving mechanism comprises a spring, a push bar, a toothed bar, a sleeve, a cover board and gears, wherein the spring is sleeved with the push bar in the sleeve, the upper end of the spring is supported on the bottom portion of the toothed bar press valve, the sleeve is fixed on the cover board, a pair of gears are fixed on the inner wall of the cover board, the toothed bar is clamped between the gears and engaged with the gears, the upper end of the toothed bar is leaned against and connected with the push bar, the left and the right arc clamps are respectively fixed on the axle of the two gears, fixed holes are arranged on the clamps, and inserted sheets with different sizes are fixed on the fixed holes. The invention is mainly used to detect the concealed contracting brake gap.
Description
Technical field:
The present invention relates to a kind of gap detection device, particularly a kind of concealed contracting brake clearance detector.
Background technology:
The iron-smelter blast furnace has raw material middle hopper gate reductor now; it is to be controlled motor rotation and stopped by the mode of braking of built-in band-type brake; when the band-type brake coil gets when electric; produce magnetic field in the coil; the adhesive brake lining; form action gap and make motor rotation; starting gate, in case magnetic field disappears during coil losing electricity, brake lining ejects by spring and resets; action gap disappears; the brake lining frictional electric machine is out of service, and reductor is through a level interval frequent starting, and the motor brake lining weares and teares; can cause motor band-type brake gap inequality, cause motor overload protection action.At ordinary times during the verification gap, adopt clearance gauge to carry out small size and detect and adjust, this method of adjustment time is long, add work under bad environment again, locational space is narrow and small, and particularly motor lower portion is difficult to adjust, often cause and adjust band-type brake gap inequality, can not reach the corresponding techniques parameter.
Summary of the invention:
The purpose of this invention is to provide a kind of concealed contracting brake clearance detector, mainly solve clearance gauge and detect the technical matters that contact area is little and be difficult to adjust.Technical scheme of the present invention is: a kind of concealed contracting brake clearance detector, comprise ratch pressure valve, ratch gear drive and clamp, described ratch gear drive comprises spring, push rod, ratch, sleeve, cover plate and gear, at sleeve inner spring socket push rod, the valve bottom is pressed against ratch in its upper end, sleeve is fixing on the cover board, a pair of gear is fixed on the cover plate inwall, ratch be stuck between gear and and gearing mesh, be abutted against with push rod the ratch upper end, about two arc clamps be separately fixed at two gear axis, on clamp, be provided with fixed orifice, thereon fixing different size inserted sheet.
The invention has the beneficial effects as follows: the transmission principle that utilizes ratch and gear, structure is flexible, tight, solid, be not easy to become flexible, reach accurate location, by the inserted sheet of different-thickness is installed on clamp, so just expanded detected band-type brake interstice coverage, the detection in the band-type brake gap that requires for various various criterions provides condition.When detecting, single also can sharp work, in mechanical industry, can both join usefulness on the similar devices.
Description of drawings:
Fig. 1 is a structural representation front view of the present invention
Fig. 2 is a structural representation left view of the present invention
Among the figure: 1. clamp 2. ratch 3. gears 4. cover plates 5. sleeves 6. push rods 7. springs 8. ratch are pressed valve 9. socket head cap screws 10. spring washers 11. nuts 12. inserted sheets.
Embodiment:
With reference to Fig. 1,2, a kind of concealed contracting brake clearance detector, comprise ratch pressure valve 8, ratch gear drive and clamp 1, described ratch gear drive comprises spring 7, push rod 6, ratch 2, sleeve 5, cover plate 4 and gear 3, at sleeve 5 inner springs 7 socket push rods 6, valve 8 bottoms are pressed against ratch in its upper end, sleeve is by socket head cap screw 9, spring washer 10 and nut 11 are fixed on the cover plate 4, a pair of gear 3 is fixed on cover plate 4 inwalls, ratch 2 is stuck between gear and with gear 3 and meshes, ratch 2 upper ends and push rod 6 are abutted against, about two arc clamps 1 be separately fixed at two gear 3 axle center, on clamp 1, be provided with fixed orifice, thereon fixing different size inserted sheet 12.When detecting, on clamp 1, pass through the inserted sheet 12 of screw retention respective thickness, clamp 1 was opened when the ratch of holding with a firm grip was pressed valve 8, insert in the band-type brake gap, unclamp ratch and press valve 8, but with regard to rapid adjustment band-type brake screw, make the gap reach the specified standard value, after this ratch of holding with a firm grip is pressed valve 8, and clamp 1 is opened automatically, and detecting device withdraws from.
