Height, when selected measurement of angle potentiometer 8 can reach the required precision of measurement apparatus, can be according to left in figure
The scheme of side is installed.When certainty of measurement requires higher, and selected measurement of angle potentiometer 8 does not reaches measurement
During the required precision of device, then install according to right side scheme in figure.In this scheme, by gear train to pendulum
Dynamic angle is amplified, and can increase the precision of measurement.
Automatic vertical detent mechanism 13 is by roll bearing swing revolving body 17 and measurement of angle potentiometer (body)
8 are connected, and make roll bearing swing revolving body and measurement of angle potentiometer 8 main body keep vertical direction.When fork 3 produces
During raw horizontal pivot angle, roll bearing swing revolving body can relatively rotate the angle equal with pivot angle with rotary body axle, partially
Angular measurement potentiometer 8 measures, by measuring this corner, the angle that fork 3 is swung indirectly.Due to plane
Automatically rotate locating mechanism 1 and can automatically determine detection direction, so steel wire rope any direction can be surveyed
Pivot angle.
The present invention applies on crawler crane, and steel wire rope deflection guiding mechanism is connected to by rope
At the hinge ear of arm head assembly pulley both sides, fork 3 is hinged with arm head installing mechanism, when steel wire rope is inclined by upper end hole
During pendulum, plane automatically rotates locating mechanism 1 and responds, and automatic vertical detent mechanism 13 makes bearing put
Kinetoplast and potentiometer 8 main body keep vertical direction, measure this corner by measurement of angle potentiometer 8 indirect
Measure the angle that fork is swung, last potentiometer or encoder 5 and measure the direction of pivot angle, so far complete
