Fig. 2 is another structural schematic diagram of deflection angle measurement device 100, and Fig. 2 is similar to Fig. 1, and different places is, pendulum
There are two connecting rod 142 and a connecting rod 141, the ends of a connecting rod 142 and the one of connecting rod 141 for the tool of angle measuring device 100
End is hinged, and the end of another connecting rod 142 is hingedly arranged on connecting rod 141, the other end and limiter 110 of connecting rod 141
Hingedly.At this moment limiter 110 is located at the same side of two connecting rods 142.The hinge joint of connecting rod 142 and connecting rod 141 can edge
The track swing of A-B in figure.The beneficial effect of such set-up mode is, limiter 110 is placed in two connecting rods 142
The same side, be conducive to the limit space 111 across limiter 110 rope 210 swung in the range of greater angle without
Influence the precision of deflection angle measurement, and measuring device is located at the side of rope 210, ensured deflection angle measurement device 100 it is succinct, can
It leans on.Further, as can be seen from the figure connection of the contact point of rope 210 and pulley 150 to rope 210 and limiter 110
The straight line of point is still parallel with connecting rod 142, allows for rope 210 in this way in the pivot angle θ and connecting rod 142 of vertical direction perpendicular
Histogram to pivot angle α it is identical, and then the angular transducer 120 by the way that connecting rod 142 and 130 hinged place of support is arranged in can be gently
It changes places and measures rope 210 in the pivot angle of vertical direction.
It should be noted that deflection angle measurement device 100 may include multiple supports 130, connector 140 includes connecting rod 141
With multiple connecting rods 142；The quantity of connecting rod 142 is identical as the quantity of support 130, one end of multiple connecting rods 142 respectively with
Its corresponding support 130 is hinged, and the other end of multiple connecting rods 142 is hinged with connecting rod 141；Limiter 110 and connecting rod 141 can
Rotationally connect.
It is the third structural schematic diagram of deflection angle measurement device 100 referring to Fig. 3, Fig. 3, shows deflection angle measurement device in figure
100 include a kind of situation of multiple supports 130 and multiple connecting rods 142.It can be seen from the figure that deflection angle measurement device 100 wraps
Include four supports, 130, four connecting rods 142 and connecting rod 141.It is cut with scissors respectively with four supports 130 one end of four connecting rods 142
It connects, the other end positioned at two connecting rods 142 of two sides is hinged with the both ends of connecting rod 141 respectively, other two connecting rod 142
The other end is hinged on the medium position of connecting rod 141；Four supports 130 are located at sustained height, and four connecting rods 142 are isometric and phase
Mutually parallel (and then connecting rod 141 is horizontal)；Limiter 110 is hinged on connecting rod 141 and is located between intermediate two connecting rods 142.
One end of rope 210 pass through limiter 110 limit space 111 connect with weight 160 or suspender, the other end of rope 210 and
Pulley 150 is slidably connected.The hinge joint of connecting rod 142 and connecting rod 141 can along figure A-B track swing.Further, it restricts
Rope 210 is still parallel with connecting rod 142 with the straight line of the tie point of limiter 110 to rope 210 with the contact point of pulley 150,
Such beneficial effect is that the pivot angle θ of rope 210 is identical as the angle [alpha] that connecting rod 142 is rotated around support 130, passes through angle
Sensor 120, which measures the angle that connecting rod 142 is swung, can be obtained by the swing angle of rope 210.
It should be noted that the structure of limiter 110 is not limited to mode described in figure.It is limit referring to Fig. 4, Fig. 4
Another structural schematic diagram of device 110.It can be seen from the figure that limiter 110 includes that support plate 114 and two can be rotatably set
Idler wheel 113 in support plate 114, the rotary shaft of two idler wheels 113 are parallel to each other；It is formed between two idler wheels 113 for supplying
The limit space 111 that rope 210 is slidably disposed through.In use, connector is arranged in being rotatably coupled in limiter 110
On 140, and the pivot center of limiter 110 is parallel with the pivot center of connector 140, rope 210 pass through two idler wheels 113 it
Between limit space 111.Shown here, the space between two idler wheels 113 just accommodates rope 210 and freely moves
Dynamic, in this way when rope 210 is swung, rope 210 drives limiter 110 mobile and then drives and is rotatably connected with limiter 110
Connecting rod 142 swing, connecting rod 142 and the angular transducer 120 of 130 hinged place of support are arranged in this way to be surveyed easily
The pivot angle of rope 210 out.Compared to the mode of sleeve 112 and rope 210 being slidably connected, such limiter 110 can
The movement between rope 210 and idler wheel 113 is set to be changed into sliding and/or rolling, so that rope 210 and the contact of limit are cleverer
It is quick, so that the pivot angle value measured is more accurate.
It should be noted that connector 140 can be other structures, four-bar linkage shown here (including hinge
The combination of chain four-bar mechanism) it is only an example, in other embodiments of the invention, connector 140 can also be other
Structure, if the angle that connector 140 can be swung rope 210 by limiter 110 pass to setting connecting rod 142 with
The angular transducer 120 of 130 hinged place of support.It is deflection angle measurement device referring to Fig. 5 as a kind of preferably embodiment
100 the 4th kind of structural schematic diagram.From figure 5 it can be seen that deflection angle measurement device 100 includes support 130, one connections
Part 140 and limiter 110.Here limiter 110 is sleeve 112.The limit that one end of rope 210 passes through limiter 110 is empty
Between 111 connect with weight 160 or suspender, the other end and the pulley 150 of rope 210 are slidably connected.Further, shown here
It is connector 140 is swing rod, one end of connector 140 and support 130 are hinged, and the other end and limiter 110 of connector 140 can
It rotationally connects, at this moment support 130, connector 140 and limiter 110 collectively form simple pendulum.Simple pendulum is relatively above-mentioned
Four-bar linkage have structure simpler, angle transmits sensitiveer feature.
The hinge joint of connector 140 and limiter 110 can along figure A-B track swing.Here it can also be seen that rope
Straight line where the contact point of rope 210 and pulley 150 to the straight line and rope 210 of rope 210 and the tie point of limiter 110 has
There is certain angle.It is swung accordingly in use, will drive limiter 110 when rope 210 is swung, limiter 110 can be corresponding
The swing of area follower link 140；The angular transducer 120 that connecting rod 142 and 130 hinged place of support is arranged in can the company of measuring
The angle [alpha] that fitting 140 is swung, this angle, which adds and/or subtract angle, can calculate the swing angle θ of rope 210.
Correspondingly, limiter 110 here is also possible to the structure in similar Fig. 4.Further, it is referring to Fig. 6, Fig. 6
Another structure type of limiter 110 in Fig. 5.It can be seen from the figure that limiter 110 can including support plate 114 and two
The idler wheel 113 being rotatably arranged in support plate 114, the rotary shaft of two idler wheels 113 are parallel to each other；Between two idler wheels 113
Form the limit space 111 for being slidably disposed through for rope 210.Different from Fig. 4, the support plate 114 of limiter 110
Plane on there is extension board 115, the co-planar of the extension board 115 and support plate 114 is provided with hinge on extension board 115
To be connect with connector 140.The connection type of such limiter 110 and rope 210 is to be slidably connected and/or roll connection,
It is more flexible, laborsaving compared to the mode of sleeve 112.
