Technical characteristics and working principle

And (3) locking under the cover:

firstly, sending an energizing instruction to the controller 9 through a remote controller, and starting the power supply 8 to supply power to the coil 12 after the central processing module 10 of the controller 9 receives the energizing instruction;

further, the coil 12 generates a magnetic field after being electrified, and the magnetic force sucks the ejector rod 14 back into the positioning hole on one side wall of the fixed sleeve 16;

at this time, the handle rod 4 is held by hand to insert the well cover 2 under the inner cover of the well ring 1;

further, the ejector rod 14 compresses the spring 13 during the suck-back process;

sending a power-off instruction to the controller 9 through a remote controller, wherein after receiving the power-off instruction, the central processing module 10 of the controller 9 cuts off the power supply of the power supply 8 to the coil 12, and the magnetic field of the coil 12 disappears;

further, the spring 13 pushes the ejector rod 14 from the inside of the positioning hole of the fixed sleeve 16 to the outer peripheral wall of the vertical rod of the handle rod 4;

further, the handle bar 4 is slowly rotated in the groove 3 on the top surface of the well cover 2 by hand, when the sound that the ejector rod 14 is elastically inserted into the insertion hole 18 of the vertical rod is heard, the handle bar 4 cannot be rotated any more, which indicates that the lock catch 17 just rotates to the bottom surface of the well ring 1 and is locked.

Unlocking and lifting processes:

firstly, sending an energizing instruction to the controller 9 through a remote controller, and starting the power supply 8 to supply power to the coil 12 after the central processing module 10 of the controller 9 receives the energizing instruction;

further, the coil 12 generates a magnetic field after being electrified, and the magnetic force sucks the ejector rod 14 back into the positioning hole on one side wall of the fixed sleeve 16;

at this time, the handle bar 4 is held by hand and horizontally rotated by more than 90 degrees, and the manhole cover 2 is lifted up by force.
