C1 is co-axially inserted fixing bolt and bottom plate the second circular hole A2 and the second mounting hole C2 are co-axially inserted fixing bolt, passes through above-mentioned fixation
Bolt pin, which is fixed, to be fixed on the luffing by detection components 4 and saves substantially at 2 rotation position of articulating point, then by adjusting institute
The relative rotation position close to switch 5 and the detection components 4 is stated, the close switch 5 is made just to detect detection block 43；This
When, it is b (referring also to Fig. 4, Fig. 5) that the luffing of measurement saves angle between 2 and ground substantially；Meanwhile it fixing described approach and opening
Closing 5 makes its position not change, and then removes the detection components 4 respectively and is fixed on corresponding aperture position the first circular hole of bottom plate A1
With the first mounting hole C1, the fixing bolt on bottom plate the second circular hole A2 and the second holes mounting hole C2 position；
Along the luffing save substantially 2 amplitude-variables to maximum allowable angle c negative directions carry out spinning movement (referring also to Fig. 6,
Fig. 7) so that the bottom plate third circular hole B1 is corresponding with the first holes mounting hole C1, and the 4th circular hole B2 of the bottom plate and second is fixed
The hole holes C2 are corresponding and clevis bolt is fixed respectively；
Next time detection when, after approaching switch 5 and detecting detection block 43 execute send out detect signal operation (referring also to scheme
8, Fig. 9)：Due to angle angle a+ angle b=angle c, so when link 1 and luffing save 2 substantially and rotate freely, if luffing
2 luffings of basic section to maximum allowable angle c, the close switch described at this time 5 just detects the detection block 43 of detection components 4
Signal limits the urgent spinning movement that the luffing saves 2 substantially by signal control.
Operation principle：
It is rotated to up to angle b on ground as shown in figure 4, saving 2 substantially in luffing first, detection components 4 is utilized into correspondence
Hole position bottom plate the first circular hole A1 and the first mounting hole C1, bottom plate the second circular hole A2 and the second mounting hole C2 are coaxially fixed on luffing base
At the rotation hinge of this section 2；By adjusting the relative position of switch 5 and detection components 4 is approached, makes to approach switch 5 and just detect
To detection block 43；Fixing close to switch 5 makes its position not change, and then removes detection components 4 and is fixed on corresponding aperture
Position is bottom plate the first circular hole A1/ the first mounting hole C1, the fixing bolt of bottom plate the second circular hole the second mounting holes of A2/ C2, along luffing
Basic section 2 amplitude-variables to maximum allowable angle c negative directions rotate so that bottom plate third circular hole B1/ the first mounting hole C1, bottom plate
4th the second mounting holes of circular hole B2/ C2 is that corresponding and bolt is fixed；Due to angle a+b=c, so when saving 2 changes substantially along luffing
Width is the signal for approaching the detection block 43 that switch 5 just detects detection components 4 to maximum allowable angle c, passes through signal
Program limitation luffing saves 2 urgent need rotation substantially.
