It is connected by upper end trip bolt group (16) with upper spacer (14) in the middle part of upper shell (8) lower end, preferably so as to energy
Fixed upper end electromagnet (12)；In upper end, the positive lower end installation lower end electromagnet (19) of electromagnet (12), lower end electromagnet (19) exist
It is connect by lower end trip bolt group (20) with lifting round platform (27) on lower clapboard (21), lifts round platform (27) outer left side and company
Connect pushing block (29) threaded connection, the external right side of lifting round platform (27) and lower housing (18) clearance fit；Connect pushing block (29) lower end
Left side and lower taper roll bearing group (32) axial restraint, connection pushing block (29) lower end right side and lifting round platform (27) are axially solid
It is fixed, pushing block (29) top and bottom axial restraint nut (30) axial restraint is connected, from lower end electromagnet (19) to center push rod
(31), sleeve mechanism can slide up and down.After upper end electromagnet (12) and lower end electromagnet (19) are passed through heterodrome, upper end
Electromagnet (12) is motionless, and lower end electromagnet (19) moves up, and in moving up, buffer spring (17), which has, mitigates two electricity
The effect of impact force between magnet inhales dynamic small electromagnet (25) and is powered to armature (26) generation suction, drives push rod (24) and limit
Position sliding block (22), and compression reseting spring (23), position limiting slide block (22) move right；When upper end electromagnet (12) and lower end electromagnetism
After iron (19) is passed through same direction current, upper end electromagnet (12) is motionless, and lower end electromagnet (19) moves down, and drives connection pushing block
(29), (31) one pieces of lower taper roll bearing group (32) and center push rod move downward, maximum stroke movement 150mm；Work as fortune
Maximum travel position is moved, position-limit mechanism starts to limit lower end electromagnet (19)；It is protective bucket (15) on the outside of upper spacer (14),
The particles such as dust can be protected to enter inside electromagnet.Dynamic small electromagnet (25) power-off is inhaled, resetting spring (23) starts multiple to the left
Position drives position limiting slide block (22), push rod (24) and armature (26) to move downward, and playing restriction lower end electromagnet (19) cannot be upward
The effect of movement simultaneously switches off the electric current of upper end electromagnet (12) and lower end electromagnet (19), to prevent electromagnet from generating
More heats influence lifting and decentralization operation for slips.It is hollow-core construction to lift inside round platform (27), and inside is cased with storage bucket
(28), storage bucket (28) is threadedly coupled with axle end baffle plate (37), and there are gaps between storage bucket (28) and lifting round platform (27)；Branch
Fagging (35) is stuck in storage bucket (28) inner cavity, guides cable from osculum pass-out.
