As shown in Figure 1, a kind of elevator door clearance meter comprises: the first noumenon 1, fixation measuring angle 2, the first scale 3, the second scale 4, chute 5, the second body 6, activity measured angular 7, spring 8, pulling force rope 9, the first pointer 10, axle 11, reel 12, winding handles 13, identification disc 14, the 3rd scale 15, knob 16, head rod 17, the second connecting link 18, the 3rd connecting link 19, support 20.
Particularly:
One end of the first noumenon 1 is provided with fixation measuring angle 2, and be provided with successively the first mm of scale 3(unit of measuring distance along the length direction of the first noumenon 1) and do not measure the second N of scale 4(unit of pulling force), described the first noumenon 1 is located at the starting point of the first scale 3.On the first noumenon 1, be provided with along its length chute 5, in chute 5, be provided with the second body 6, the second bodies 6 and slide along chute 5 under the pulling force of pulling force rope 9.The inside that chute 5 can be positioned at the first noumenon 1 also can be stuck on the first noumenon 1 side.The second body 6 is provided with activity measured angular 7, and activity measured angular 7 is stretched out the first noumenon 1, and the starting point of activity measured angular 7 corresponding described first scale 3 under original state, and the second body 6 while sliding described in corresponding described the first scale 3 of activity measured angular 7.Activity measured angular 7 is corresponding with fixation measuring angle 2, and locates at grade, is convenient to measure extend in object gap and under pulling force, object is strutted to certain distance (this distance can be zero).
Spring 8 is located in chute 5, and its pulling force is corresponding with described the second scale 4.Tensile elements comprises pulling force rope 9, one end linking springs 8 of pulling force rope 9.Pulling force rope 9 is provided with the starting point of the first pointer 10, the first pointers 10 corresponding second scale 4 under original state, and tensile elements while moving described in corresponding described the second scale 4 of indication piece.Between spring 8 and the second body 6, be provided with calibrating installation, calibrating installation comprises knob 16, and one end of knob 16 has is with externally threaded axle, and the second body 6 is provided with tapped hole, in this axle precession hole.The surface of knob 16 is positioned at the first noumenon 1 outside, stirs this surface and makes its rotation, makes axle rotation, and the position, left and right of adjusting knob 16, thereby the position of regulating spring 8 make the starting point of the first pointer 10 corresponding second scale 4 under original state of tensile elements.
According to the present embodiment preferred exemplary, it also comprises collecting device, described collecting device comprises and can, along the reel 12 of a fixing axle center rotation, be wound on one end of described pulling force rope 9 on reel 12, also comprises and control the winding handles 13 that described reel 12 rotates.Particularly, reel 12 is rotatably installed on an axle 11, reel 12 connects winding handles 13, this axle 11 can be not rotatably directly or indirectly and the first noumenon 1 be fixed together, directly connect the two ends that extend to axle 11 such as the first noumenon, axle 11 is fixed on the first noumenon, indirectly connects such as the two ends of axle 11 connect the first noumenon by support.The axle at Ji Zhiqi center, described fixing axle center is that relative the first noumenon 1 is fixed.Can find out, rotate reel 12 by winding handles 13, can either impose well pulling force to pulling force rope 9, and in the time that the first pointer 10 is indicated to set scale, be easy to again fixing wound handle 13, make the first instruction be fixed on indicated position, thereby be convenient to the reading of the first scale 3.Advantageously, be provided with the identification disc 14 not rotating with reel 12 in a side of reel 12, identification disc 14 is fixed on axle 11.Identification disc 14 can be circular, can be also other shape.Identification disc 14 is provided with the 3rd scale 15, the three scales 15 and is positioned at the outside of described reel 12, and reel 12 is provided with the second pointer, corresponding described the 3rd scale 15 of the second pointer in the time that reel 12 rotates.The 3rd scale 15 can form circle, fan-shaped or other shape.Advantageously, the 3rd scale 15 and the concentric setting of reel 12.Hence one can see that, although the first pointer 10 can be indicated value of thrust, but while repeatedly measurement, the first pointer 10 is difficult to accurately point to same position, again due to due to human eye error, make each pulling force all the same, especially, when testee gap is during in qualified and defective critical limit, the slight variation of the first pointer 10 indicating positions may cause diverse result.And because the 3rd scale 15 is positioned at reel 12 outsides, the slight variation of the first pointer 10 indicating positions just can make the second pointed the 3rd scale 15, and great changes will take place.Therefore this structure has the following advantages: (1) repeatedly when duplicate measurements, makes the indicating positions of the second pointer be positioned at identical graduation after each coiling, and the pulling force that applied is identical, has greatly reduced error; (2) after first calibration, remember the scale that the second pointer is indicated, each only measurement need be rotated the second pointer to this scale later.
In addition, the first noumenon 1 is connected with head rod 17 and the second connecting link 18, head rod 17 and the second connecting link 18 are all bolted on support 20, and the two ends of described axle 11 connect the 3rd connecting link 19, the three connecting links 19 and are also bolted on support 20.
The invention solves in elevator door gap detection process and apply the problem that power can not quantize, reduced labour intensity, improved the precision of detected value, accuracy value: 1mm, can ensure the quality that elevator is checked.
During according to the measurement device of measurement clearance of the present invention, fixation measuring angle 2 and activity measured angular 7 are extend in object gap (as elevator door gap), pull tensile elements by spring 8, the second body 6 to be moved right, in the time that indication piece the second scale 4 is indicated to default pulling force (as 150N), read the scale that activity measured angular 7 is indicated on the first scale 3, be object gap.To sum up, the present invention have rational in infrastructure, easy and simple to handle, measure the advantages such as accurate.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present invention and aim, can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present invention is limited by claim and equivalent thereof.
