Embodiment
With reference to embodiment accompanying drawing, the invention will be further described.
This automatic lifting follows the structure of mechanical safety as shown in Fig. 1~Fig. 5：
The present apparatus includes fixed seat, sliding seat and power train three parts.Fixed seat by 1, four bearing column 2 of bearing soleplate, on
Fixed plate 3 forms；The bearing column 2 is hollow thick-walled pipe, and four bearing columns 2 are symmetrically welded on bearing soleplate 1；It is described
A through hole is provided among upper mounted plate 3, corner is provided with four symmetrical step through-holes, four through holes and four bearing columns
Hole is coaxial, equal in magnitude, and upper mounted plate 3 is welded and fixed with four bearing columns 2；Oil cylinder 11 is placed among bearing soleplate 1, is worn
Cross the interstitial hole of upper mounted plate 3, the upper surface of bearing soleplate 1 and the lower surface of upper mounted plate 3 and be respectively provided with four bolt lockings around oil cylinder
Seat 12, is centrosymmetrically arranged, and bolt locking bed 12 carries out centering to oil cylinder 11 equipped with bolt and fixed.
The sliding seat is made up of four screw mandrels 6 and connection top plate 4.Connection top plate 4 is provided with symmetrical four shoulder holes, leads to
Bolt 17 is crossed to be attached with screw mandrel 6；Connection top plate 4 center is provided with manhole, and two are arranged with manhole periphery
Tapped through hole, is mounted with proximity switch 19 and 20 in hole respectively, the upper surface of proximity switch sink to connection top plate 4 upper surface it
Under；Screw mandrel 6 is cylindrical to be provided with trapezoidal thread, is furnished with barrel nut 14 on screw thread, screw mandrel 6 is mounted in bearing column 2 by nut 14
Through hole in, the afterbody of screw mandrel 6 is equipped with guide sleeve 23, coordinates with the via clearance of bearing column 2 and is oriented to.
The power train is made up of barrel nut 14, turbine 16, worm screw 5, bevel gear 8, T-shaped reductor 9, motor 10,
Barrel nut 14 coordinates in the step through-hole of upper mounted plate 3 with screw mandrel 6, and the circular lid of through hole is provided with one piece of center
Plate 15 is covered on upper mounted plate 3, and barrel nut 14 is limited in the step through-hole of upper mounted plate 3 and rotated freely, and turbine 16 is logical
Cross the through hole of circular cover 15 to be screwed on barrel nut 14, worm screw 5 engages with turbine 16, and the both ends of worm screw 5 are equipped with axle
Bearing 7, bearing block 7 are fixed on upper mounted plate 3, and the right-hand member of worm screw 5 is equipped with bevel gear 8；T-shaped reductor 9 is fixed on upper mounted plate 3
On, provided with two symmetrical output shafts 13 and 21, nibbled on output shaft 13 and 21 equipped with bevel gear and the bevel gear 8 of the end of worm screw 5
Close；The T-shaped input of reductor 9 is equipped with motor 10.
In ascending fashion, original state, the proximity switch 19 of connection top plate 4（It is normally opened）For closure state, controlled motor
10 start, and driving reductor 9 works, and speed reducer output shaft delivers torque to circular spiral shell by bevel gear 8, worm screw 5, turbine 16
Mother 14, step through-hole internal rotation of the nut 14 on upper mounted plate 3, drive screw 6 rises, and screw mandrel drives connection top plate 4 to rise
Until proximity switch 19 and 24 distances of load reach setting value, proximity switch 19 disconnects, and controlled motor delay stops, and nut 14 stops
Rotation stop is moved, and connection top plate 4 stops rising.Oil cylinder 11 acts, and piston rod 22 stretches out, and jacking load rises, and load 24 rises to big
In the setpoint distance of proximity switch, the proximity switch 19 of connection top plate 4（It is normally opened）Closure, controlled motor 10 are started, and driving is slowed down
Machine 9 works, and speed reducer output shaft delivers torque to round nut 14 by bevel gear 8, worm screw 5, turbine 16, and nut 14 is upper
Step through-hole internal rotation in fixed plate 3, drive screw 6 rise, and screw mandrel drives connection top plate 4 to rise.Screw mandrel speed is set to omit
More than the oil cylinder rate of climb, when connect top plate 4 rise towards the setting of switch 19 apart from when, proximity switch 19 disconnects, control
Motor delay stops, and nut 14 stops operating, and connection top plate 4 stops rising, and connection top plate 4 is kept with load 24 in setpoint distance
It is interior.When oil cylinder continues jacking load 24, when load 24 rises above the setpoint distance of proximity switch, power train repeats above-mentioned again
Action, drive connection top plate 4 rise, and follow the movement of load 24 all the time, and be maintained within setpoint distance with load 24（Such as Fig. 6
It is shown）.
In drop mode, original state, the proximity switch 20 on top plate 4 is connected（It is normally closed）For closure state, control electricity
Machine 10, which starts, to be reversely rotated, and driving reductor 9 is worked, and speed reducer output shaft is passed moment of torsion by bevel gear 8, worm screw 5, turbine 16
Round nut 14, step through-hole internal rotation of the nut 14 on upper mounted plate 3 are passed, drive screw 6 declines, and screw mandrel drives connection
Top plate 4 declines, and when the proximity switch 20 on connection top plate 4, which leaves load 24, reaches setpoint distance, connects connecing on top plate 4
Nearly switch 20 disconnects, and controlled motor delay stops nut 14 and stopped operating, and connection top plate 4 stops declining；
When oil cylinder 11 acts, piston rod declines, and jacking load 24 declines, and load 24 drops to less than proximity switch 20（It is normally closed）'s
Setpoint distance, proximity switch 20 are closed, and controlled motor 10, which starts, to be reversely rotated, and driving reductor 9 works, and speed reducer output shaft leads to
Cross bevel gear 8, worm screw 5, turbine 16 and deliver torque to round nut 14, nut 14 is in the step through-hole on upper mounted plate 3
Rotation, drive screw 6 decline, and screw mandrel drives connection top plate 4 to decline.Because screw mandrel speed is slightly larger than oil cylinder decrease speed, work as connection
Top plate 4 drop to close to the setting of switch 20 apart from when, proximity switch 20 disconnects, and controlled motor delay stops, and nut 14 stops
Rotate, connection top plate 4 stops declining, and follows load to move all the time, and is maintained at load 24 within setpoint distance.
When finally needing the present apparatus to realize mechanical support with load contact, manual mode can be entered, controlled motor starts,
Drive screw rises, and drives connection top plate 4 to rise, contacts until with load support face, then stop.At this moment oil cylinder can fall
Unloading, load total weight are supported by this mechanical safety, helicitic texture self-locking, it is ensured that 24 support safeties of load and equipment peace
Entirely.
In summary, no matter rise or fall, the present apparatus can follow load to move all the time, and be maintained at and set with load
Within set a distance, it is ensured that the safety of load jacking process.
