Description
Technical field
The present invention relates to the outer corner measurement technology in the machinery, relate in particular to a kind of corner measuring apparatus.
Background technology
In order to realize certain demand or requirement, the mechanism that some bands rotate needs to measure the angle of its rotation under some occasion.The tank car of embracing as metallurgical steel mill when projection electronic weighing calculates tank body load, need calculate working arm moment, therefore must measure the angle parameter of some tumblers, but these positions are often because compact conformation, and the outer corner measurement instrument can't directly be measured.Therefore need a kind of indirect outer corner measurement technology.
Summary of the invention
The purpose of this invention is to provide a kind of corner measuring apparatus, can't directly measure the technical matters of corner in order to solve some rotating mechanism.
The present invention has adopted following technical proposals:
A kind of corner measuring apparatus, comprise first pivoted arm, second pivoted arm and outer corner measurement instrument, first pivoted arm and second pivoted arm are hinged, in addition, also comprise first connecting rod and second connecting rod, wherein, one end of first connecting rod and an end of second connecting rod are hinged, the other end of first connecting rod and first pivoted arm are hinged, the other end of second connecting rod and second pivoted arm are hinged, first, second pivoted arm and first, second connecting rod is common to constitute a parallelogram, and four pin joints are four summits of parallelogram, and the outer corner measurement instrument is positioned on arbitrary pin joint except that first pivoted arm and the second pivoted arm pin joint.Preferably, the outer corner measurement instrument is positioned on the pin joint of arbitrary pivoted arm and connecting rod.
Principle of work of the present invention as shown in Figure 1, first pivoted arm 1 and second pivoted arm 2 are articulated in the C point, one end of first connecting rod 3 and an end of second connecting rod 4 are articulated in the F point, the other end of first connecting rod and first pivoted arm are articulated in the E point, the other end of second connecting rod and second pivoted arm are articulated in the G point, GC=EF, CE=GF, form parallelogram between pivoted arm and connecting rod, four pin joint E, F, G, C is four summits of parallelogram EFGC, equate according to the parallelogram diagonal angle, the principle of adjacent angle complementation, when inconvenience is directly measured corner between first pivoted arm and second pivoted arm, measure E, F, the angle of any one point all can convert and obtain corner between first pivoted arm and second pivoted arm among the G.
Another purpose of the present invention is to disclose a kind of armful of tank car corner measuring apparatus, comprise the big arm of work, the vehicle frame platform, work big arm one end and vehicle frame platform one end is hinged, in addition, also comprise first connecting rod, second connecting rod and outer corner measurement instrument, wherein, first connecting rod one end and second connecting rod one end are hinged, the first connecting rod other end is hinged with the big arm of work, the second connecting rod other end and vehicle frame platform are hinged, the big arm of working, vehicle frame platform and parallelogram of two common formations of connecting rod, four pin joints are four summits of parallelogram, the outer corner measurement instrument is on the pin joint between arbitrary pivoted arm and connecting rod or connecting rod and the connecting rod.Preferably, the outer corner measurement instrument is positioned on the pin joint of second connecting rod and vehicle frame platform, so that reading.
By corner measuring apparatus of the present invention is installed, can measure the corner that needs easily, be convenient to simultaneously install, convenient, reliable.Be applicable to the occasion of the direct installing angle measuring instrument of multiple inconvenience.

Embodiment
An embodiment of the invention:
Embrace tank car working machine composition as shown in Figure 2, form by telescopic oil cylinder 5, the big arm 6 of work, vehicle frame platform 7.Wherein telescopic oil cylinder cylinder body and vehicle frame platform are articulated in the A point, and the telescopic oil cylinder piston rod head is articulated in the B point with the big arm of work, and work big arm and vehicle frame platform are articulated in the C point.When telescopic oil cylinder was done stretching motion, the big arm of the working vehicle frame platform C point of can having mercy on moved in a circle.As shown in Figure 3, Figure 4, when telescopic oil cylinder shrank piston rod, the big arm of working moved in a circle, and slag ladle 8 is thus lifted on the vehicle frame platform 7 from ground.
When slag ladle 8 was raised, the moment sum that telescopic oil cylinder 5 and slag ladle 8 act on the working arm equated, therefore can try hard to recommend out slag ladle load by measuring oil cylinder, just needs the rotational angle theta of the big arm of work in computation process.
During with angular transducer big arm of (outer corner measurement instrument) surveying work and the horizontal angle theta of vehicle frame, because C position revolute is in the car body outermost, if direct installing angle measuring instrument, just must outside revolute, increase the extension support, the fixation measuring instrument, make measuring instrument be directly exposed to outermost, and make overall width increase, can be often by foreign object percussion (the C point be inboard owing to there is buttress brace also can't install).
Be big arm of surveying work and the horizontal angle theta of vehicle frame, adopt a corner measuring apparatus, as Fig. 5, shown in Figure 6, on the big arm 2 of work, be a pin joint E, below the big arm of work, determine 1 G installing angle measuring instrument on the vehicle frame, be the connecting rod EF (being first connecting rod) and the connecting rod GF (being second connecting rod) of two band swivel pins, the big arm 6 of working is articulated in the E point with connecting rod EF, and vehicle frame platform 7 is articulated in the G point with connecting rod GF, wherein, GC=EF, CE=GF so makes parallelogram CGFE, when the big arm of work rotates, the parallelogram linkage action, the corner of the bar GF that the outer corner measurement instrument is measured promptly is the rotational angle theta of the big arm of work.
