The alignment pin upper end is switched equipped with electric machine spacing.
The rotational positioning system is provided with 90 degree of limit switches and 180 degree limit switch, and real by particular electrical circuit system
Existing 0-360 degree Arbitrary Rotation.
The positioning fluted disc is provided with oval positioning hole.
Anti-wear sleeve is provided between the alignment pin and hook body.
The alignment pin end is provided with pin hole shackle hook support.
Beneficial effects of the present invention：In the use of the present invention, shackle hook group is switched on power, now electromagnet is in logical
Electricity condition, pulls link, while affecting alignment pin, alignment pin is extracted the oval positioning hole of positioning fluted disc, now
The upper end of alignment pin connects electric switch with motor and contacted, and motor is started working；Motor by moment of torsion by reductor, shaft coupling and
Little gear is delivered to positioning fluted disc, and now suspension hook, which is realized in rotation, electric cabinet, is provided with A.C. contactor, passes through particular electrical circuit system
System and 180 degree limit switch, 90 degree of limit switch collective effects, realize that suspension hook 0-360 spends the positive and negative rotation of any angle crawl
It is accurately positioned with 90 degree, 180 degree, 270 degree, when limit switch is opened, electromagnet power-off makes link affect calmly by deadweight
Position bearing pin is downwardly into the positioning hole of positioning fluted disc, is left while alignment pin upper end connects electric switch with motor, motor power-off
Stop operating, employ after above-mentioned technical proposal, the present invention can realize that suspension hook 0-360 spends the positive and negative rotation of any angle crawl
Turn；Realize suspension hook be rotated by 90 °, 180 degree, 270 degree be accurately positioned；Need rotation 180 degree positioning when, can skip 90 degree it is direct
Rotating to 180 degree makes suspension hook accurate positioning, safety, and the present invention realizes the accurate control of lifting weight, effectively reduces behaviour
Make the labor intensity of workman, more reduce the potential safety hazard during use.
