In order to illustrate technical scheme and technique effect, below in conjunction with the accompanying drawings and the present invention is described further by specific embodiment.
In an embodiment as shown in Figures 1 to 8:
Hoisting permanent magnet includes housing 10 and the motor being arranged in housing, drive mechanism, magnetic rotating shaft 11 and is arranged on the permanent magnet in magnetic rotating shaft 11.Described motor drives left magnetic axis of rotation, and left magnetic rotating shaft drives right magnetic rotating shaft to rotate backward with identical angular velocity by a pair gear.Housing 10 bottom surface is the holding face holding steel billet 12.
The magnetic Shaft Torque balancer being arranged on this hoisting permanent magnet, including support 4, steel wire rope 7, spring part, some pulleys, locating piece and regulating wheel 6.
Described support 4 is arranged on hoisting permanent magnet housing 10, is positioned at the top of hoisting permanent magnet two magnetic rotating shaft.Support 4 includes left and right two carrier units, and two stands cellular construction is symmetrical, is equipped with dividing plate and pulley installing plate.Leaving certain distance between the dividing plate of two stands unit, pulley installing plate is arranged on the outside of dividing plate.
Steel wire rope 7 includes that left and right two sections of steel wire ropes, every section of steel wire rope are made up of two steel wire ropes, totally four fag ends.One of these two steel wire ropes is docked at length adjusting mechanism 1, and other end is used for connecting extension spring.
Described spring part includes the upper extension spring 2 between two stands cell separators and tension spring 3, and the two ends of upper extension spring 2 and tension spring 3 are connected with the steel wire rope through carrier unit dividing plate respectively, and upper extension spring 2 tension spring 3 is parallel.
Described pulley includes upper and lower two pulleys being separately positioned on two stands unit and the pulley 8 being installed at two magnetic roller end, and the center of rotation of the center of the pulley 8 being installed in magnetic rotating shaft and corresponding magnetic rotating shaft is point-blank.
In figure, the head end of left section of steel wire rope is connected with the left end of upper extension spring 2, after its rope body passes the dividing plate of left socle unit, from the outside of left socle unit top sheave, the outside of the left magnetic rotating shaft bottom and left socle unit lower sheave that install pulley additional walks around successively, after this rope body again passes through the dividing plate of left socle unit, rope body end is connected with the left end of tension spring 3；The head end of right section of steel wire rope is connected with the right-hand member of upper extension spring 2, after its rope body passes the dividing plate of right support unit, from the outside of right support unit top sheave, right magnetic rotating shaft install bottom and the lower sheave of right support unit of pulley additional, after this rope body again passes through the dividing plate of right support unit, rope body end is connected with the right-hand member of tension spring 3.Walk around magnetic rotating shaft to install additional and be sheeted in the middle part of the steel wire rope of pulley and screw 9 compresses locking, prevent steel wire rope from sliding in the race installing pulley additional.Magnetic rotating shaft is installed the steel wire rope body between pulley and unit rack pulley additional and is all walked around a regulating wheel 6.
It is separately installed with a positioning block 5 on steel wire rope body between upper extension spring 2, tension spring 3 to the dividing plate of right support unit, between this dividing plate to the upper and lower pulley of right support unit.
If setting extension spring to the locating piece between dividing plate is right energy storage locating piece as the locating piece between left energy storage locating piece, dividing plate to carrier unit pulley, then its operational process is:
One) inhale ferrum operation, see Fig. 1 to Fig. 4 and Figure 10.
A) ferrum position (see figure 1) is put completely.Hoisting permanent magnet bottom surface, without magnetic field, is in and puts ferrum state completely.Magnetic rotating shaft 11 is in the initial position of 0 °, at this moment goes up extension spring 2 and is in energy storage state, and tension spring 3 is in free state.Starting motor, drive left magnetic rotating shaft to turn clockwise, right magnetic rotating shaft produces the angular velocity (rotation direction be counterclockwise) identical with left magnetic rotating shaft under the power of a pair gear is transmitted, and upper extension spring 2 and energy storage locating piece above start to move right.
B) when magnetic rotating shaft 11 forwards 35 ° of positions to (see Fig. 2), left energy storage locating piece above moves on to carrier unit partition position, it is impossible to move right again, along with magnetic rotating shaft 11 is rotated further, upper extension spring 2 length starts to shorten, and discharges spring potential energy, helps motor to drive magnetic axis of rotation.
C) when magnetic rotating shaft 11 forwards 62 ° of positions to (see Fig. 3), upper extension spring 2 energy storage release terminates, and is in free state.Stopping at the partition position of following right energy storage locating piece traversing carriage unit, tension spring 3 starts energy storage.
D) when magnetic rotating shaft 11 forwards 90 ° of positions to (see Fig. 4), tension spring 3 energy storage terminates.Magnetic field, hoisting permanent magnet bottom surface reaches maximum, is in maximum suction ferrum state, is also the starting position putting ferrum operation.
Two) put ferrum operation, see Fig. 5 to Fig. 8 and Figure 10.
A) maximum suction ferrum position (see Fig. 5, be equal to Fig. 4).Motor drives left magnetic rotating shaft to rotate counterclockwise, and tension spring 3 and following energy storage locating piece move right, and upper extension spring 2 and energy storage locating piece above are moved to the left.
B) when magnetic rotating shaft forwards 59 ° of positions to (see Fig. 6), left energy storage locating piece below moves on to right support cell separators position, and the most motionless, tension spring 3 starts to release energy, and side group motor drives magnetic rotating shaft.
C) when magnetic rotating shaft forwards 35 ° of positions to (see Fig. 7), tension spring 3 releases energy, and terminates to energy storage release during 7 ° of positions；Upper extension spring 2 starts stretching, and right energy storage locating piece above moves to the left, moves on to the partition position of right support unit, it is impossible to be moved to the left during to 19 ° of positions again, and along with left magnetic rotating shaft continues to rotate counterclockwise, steel wire rope pulls extension spring 2 to carry out energy storage.
D) when magnetic rotating shaft forwards 0 ° of position to (see Fig. 8), upper extension spring 2 energy storage terminates, and inhales the starting point of ferrum next time.
By the contrast of load torque in Fig. 9 Yu Figure 10, it can be seen that the maximum load moment of torsion of former hoisting permanent magnet is 18.4KN, after installing the present embodiment device additional, maximum load moment of torsion is 12.6KN, and the power of motor used only has the 68% of original equipment.
Extension spring in above-described embodiment, adjusting pole unit, energy storage locating piece arrangement position after, it is possible to use stage clip substitute.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and claimed scope is defined by appending claims, description and equivalent thereof.
