Background technology
Industries such as big machinery, shipbuilding and metallurgy are to lifting or main lifting electromagnet, hoisting permanent magnet, permanent magnet sucking hoisting apparatus, permanent magnetic lifter, steel rope and the steel plate pincers of using of carrying of iron and steel now.The lifting electromagnet corollary equipment is many, the productive costs height, power is big, and the energy consumption height runs into unexpected power failure, absorbate can drop, even be furnished with the precious magnetic of power failure, also can only keep very short time (about 15 minutes), this time does not send a telegram here or will do not inhaled steel puts down if surpass, the steel case accident equally also can appear being inhaled, and very dangerous; Though hoisting permanent magnet will be got well much than electromagnet in energy consumption and safety, because of the limitation of its constructional feature, can not inhale in the air blowing, can not Long-distance Control, the magnetic force size can not regulate, thereby its range of use is restricted; In a single day permanent magnet sucking hoisting apparatus is made, and its magnetic circuit is immutable, it can only lifting greater than the plate iron of pole surface, range of use is littler, and suction has only several tons; Though permanent magnetic lifter uses flexibly, need M/C to inhale discharging, exist some potential safety hazards to making the littler with scope of it like this, only be used in small-sized machine up; And steel rope and steel plate pincers are the most original and the way of old soil, its inefficiency, and labour intensity is big, and potential safety hazard is bigger.
Summary of the invention
The object of the present invention is to provide a kind of hoisting permanent magnet, particularly automatically controlled hoisting permanent magnet.
The object of the present invention is achieved like this.
1) utilize rare-earth permanent magnet as magnetic source, the permeability magnetic material of two semi arches becomes axle with two non-magnetic conduction spindle nose welding processing, be empty between the permeability magnetic material of two semi arches, the rare-earth permanent magnet of the box-shaped of the some of can packing into has just been formed magnetic axis behind the rare-earth permanent magnet of the some of packing into; Two very the circular-arc pole shoe of magnetic conduction become magnetic pole with the non-magnet material welding processing; Magnetic axis is packed in the magnetic pole, and magnetic axis can rotate in magnetic pole, and the magnetic axis of packing in the magnetic pole has just formed an independent magnetic cell.When magnetic axis rotated, the magnetic circuit in the magnetic cell can carry out varying cyclically with closed circuit at open circuit, and when the magnetic circuit of magnetic cell the inside during for open circuit, magnetic cell is apparent magnetic externally, ferromagnetic materials can be held; When the magnetic circuit in the magnetic cell when being closed circuit, magnetic cell does not externally show magnetic, and this moment, magnetic cell was not inhaled ferromagnetic materials.
2) a plurality of magnetic cells are combined into magnetic suction disc according to certain rules, all magnetic axises in the magnetic suction disc are rotated synchronously or stop by external force, externally show magnetic synchronously or do not show magnetic to realize a plurality of magnetic cells, inhale ferromagnetic materials or discharging thereby externally form.
3) magnetic axis with a plurality of magnetic cells links to each other by sprocket wheel, arrive reducing motor through two pairs of reducing gear then, when reducing motor rotated like this, magnetic axis just can rotate, magnetic cell realizes externally showing magnetic or does not show magnetic by the rotation of reducing motor, unloads ferromagnetic materials thereby realize inhaling.
4) turning effort of a plurality of magnetic cell magnetic axises is from reducing motor, reducing motor is controlled by button or remote controller, cooperate magnetic force high-order spacing near switch with the low level metal, realize the rotation of magnetic cell magnetic axis or stop, make each magnetic cell under automatically controlled situation, externally show magnetic or apparent magnetic simultaneously, realized as lifting electromagnet or hoisting permanent magnet suction or discharging from face.
The concrete technical scheme of the present invention is: a kind of automatically controlled hoisting permanent magnet, have reducing motor, and driving gear pair, chain wheel driving mechanism, support, top board, electric cabinet, spacing near switch, remote controller, rare-earth permanent magnet, magnetic axis, magnetic pole; It is characterized in that: reducing motor is arranged on the support; Support is arranged on the top board; Also be provided with electric cabinet on the support; Be provided with electric control panel in the electric cabinet; The imput shaft of described driving gear pair driving gear is arranged on the support, and the worm gear center of passing reducing motor is attached thereto; The transmission shaft of ring gear and imput shaft are set in parallel on the support; Transmission shaft is provided with the location sensitive sheet, spacingly is arranged on transmission shaft one side near switch, and is corresponding with the location sensitive sheet; It is coaxial with ring gear that the axle head of transmission shaft is provided with sprocket wheel; Form magnetic cell by rare-earth permanent magnet, magnetic axis and magnetic pole, magnetic cell is a plurality of, and described magnetic cell is arranged parallel to each other to be assembled on the interior side plate of top board and forms magnetic suction disc; The rare-earth permanent magnet of each magnetic cell is contained in the magnetic axis, is driven by driving gear pair and chain wheel driving mechanism by reducing motor and rotates in magnetic pole; The start and stop of reducing motor are controlled by the electric control panel in the electric cabinet by remote controller.
Rare-earth permanent magnet in each magnetic cell of the present invention is square, and two blocks of permeability magnetic materials with respect to indent semicircle arcuation are isolated welding processing with two non-magnet materials and become magnetic pole; Two blocks of magnetic inductive block materials with respect to the evagination semi arch become axle with two non-magnetic conduction spindle nose welding processing, it is the empty rare-earth permanent magnet that can adorn box-shaped between the permeability magnetic material of two evagination semi arches, pack into and just formed magnetic axis behind the rare-earth permanent magnet, two dress bearing of magnetic axis, one also is equipped with the duplex chain wheel.
The present invention only uses a support, a reducing motor (band RV drop-gear box), and reducing motor is for exchanging the motor of RV reducing motor or direct current RV reducing motor or belt brake.Imput shaft is passed from motor reduction gearbox, a driving gear is installed at two ends (also can an end), the ring gear that driving gear drives the below rotates, and on ring gear is coaxial sprocket wheel is housed, and the duplex chain wheel on the magnetic axis of magnetic cell at two passed to power respectively by coaxial sprocket wheel by ring gear.Each independent magnetic cell is connected with reducing motor by sprocket wheel, chain, gear, drives synchronized operation by a reducing motor.
In order magnetic cell accurately to be turned to externally manifest maximum magnetic force or not show magnetic force, a location sensitive sheet is housed on the transmission shaft, also be equipped with at the top board of rotating shaft one side spacing near switch, with the accurate off-position of control motor.
