By means of designs of reasonable magnetic circuits and the mechanical transmission device, the permanent-magnet lifting jack can be in iron attracting and iron releasing states automatically, and the problems of complexity in operation and low safety in existing plate lifting can be solved. The automatic permanent-magnet lifting jack is safe and reliable in performance and convenient to use, and labor is relieved as no more manual operation is needed.
Description
One, technical field
The utility model relates to a kind of permanent magnetic lifter that is applicable to industry sheet material carryings such as steel mill, shipbuilding yard, machine up factory.
Two, background technology
Adopted instruments such as steel rope, hoisting tongs during handling sheet material in the past; At first need the workman to tie steel plate or use hoisting tongs to block steel plate with steel rope; And then pass through driving and arrive the destination to the sheet material handling, also need the workman to untie steel rope or open hoisting tongs after falling, this mode of operation is extremely loaded down with trivial details; Greatly reduce work efficiency, and the workman exists potential safety hazard near sheet material.Appearing at of electromagnet solved inefficient problem to a certain extent, yet electromagnet needs the power supply power supply, and be very inconvenient at some special occasions.
Along with magnetic material in recent years fast development, the rare earth permanent-magnetic material nd-fe-b is used widely, permanent magnetic lifter occur thereupon and obtain constantly progressive and perfect, yet also there is following shortcoming in permanent magnetic lifter at present:
1, can only handling smaller piece sheet material can not whole steel plate of handling;
2, magnetic is that the two poles of the earth conversion is inaccurate, causes suction to reduce, and sheet material very easily comes off;
3, when maloperation occurring, very easily damage Jack, the Jack performance is reduced greatly.
Three, summary of the invention
The purpose of the utility model provides a kind of power supply that do not need and supplies power, but the larger-size monoblock steel plate of handling, and performance is safe and reliable, automatic permanent magnetism hoisting jack easy to use.
The technical scheme that the utility model adopts is: automatic permanent magnetism hoisting jack comprises suspension ring, suspension rod, mechanical drive and magnetic system; It is characterized in that: magnetic system is made up of some minutes magnetic systems; Every component magnetic is all is to be made up of magnetizer axle sleeve, permanent-magnet material and rotating shaft; Upper and lower at the magnetizer axle sleeve is fixed with permanent magnet respectively, and upper and lower permanent magnet opposite pole is relative, in the rotating shaft of centre, also is fixed with and the corresponding permanent magnet of upper and lower permanent magnet.
The utility model is fit to many All-China Federation of Taiwan Compatriots and uses; When the handling material, many permanent magnetic lifters are placed on the sheet material material in proper order, and hoisting crane is through the suspension ring on the hanging beam pulling Jack; Suspension ring spur left and right sides suspension rod above the Jack again and make the axle on the horizontal direction rotate corresponding angle then; And then making driving gear also rotate 45 °, driving gear is that shaft rotates 180 ° through mechanical drive drive branch magnetic then, makes that the permanent-magnet material magnetic pole in the rotating shaft just in time also rotates 180 °.Suppose that permanent magnetic lifter is in the iron state that unloads when rotating shaft is not rotated;, ratchet makes that magnetic is after spindle nose rotates 180 ° after driving ratchet and then drive mechanical drive gear; Jack just in time is in the iron state of inhaling; Hoisting crane is moved the destination to steel plate through Jack, and the suspension rod of Jack moves down and then drives ratchet and drives 45 ° of ratchet rotations under the effect of gravity when steel plate touches the destination, makes that through the mechanical rotation gear magnetic is that spindle nose rotates 180 ° once more again; Magnetic is that axial region polarity changes once more and makes the inner C/LOOP Jack that forms of magnetic system be in and unload the iron state, and steel plate is removed.
The utility model makes permanent magnetic lifter be in suction iron automatically through rational magnetic circuit and mechanical drive (click, driving gear, driven gear etc.) design and unloads the iron state.Complicated operation when the utility model has solved sheet material handling in the past, the problem that safety performance is low.Properties of product are safe and reliable, and are easy to use, do not need more manual operation, alleviated labor content.

Five, the specific embodiment
The permanent-magnet material that the utility model is selected for use is a nd-fe-b.Mechanical drive is made up of ratchet 4, ratchet 5, driving gear 6, bayonet lock 7 and spring 8, and driving gear 6 is coaxial with ratchet 5.Driving gear 6 drives the rotating shaft 9 that each component magnetic is through driven gear, and its transmitting ratio is 1: 4.
The initial condition of supposing many All-China Federation of Taiwan Compatriots use automatic permanent magnetism hoisting jack is for unloading the iron state; When the handling steel plate, at first the suspension hook of suspension ring 1 below the hoisting crane hanging beam of many Jacks linked to each other; Be placed on Jack near the sheet material center of gravity on the position then, the rising suspension ring 1 that drive hanging beam along with hoisting crane will drive suspension rod 2,3 and rise, and then drive ratchet 4 and promote ratchets 5 rotating certain angle; Ratchet 5 is coaxial with driving gear 6; Rotate so drive driving gear 6, when ratchet 5 turns to 45 °, at this moment (rotate in the opposite direction making it under the effect of spring 8 and be stuck on the ratchet 5 even have unexpected situation to make suspension rod 2,3 move down also to be unlikely to drive ratchet 5 at the positioning contact 7 at the positioning base place in ratchet 5 outsides; Guaranteed the reliability of system); Spindle nose 9 in the magnetic system has rotated 180 ° under the drive of driving gear 6 at this moment, makes the polarity of permanent-magnet material exchange, and the permanent magnet 14 of the interior permanent magnet 13 of the permanent magnet 12 on magnetizer axle sleeve 10 tops and axle, bottom and the interior permanent magnet 13 of axle are same polarity and (are all the N utmost point and perhaps are all the S utmost point) relatively; Sheet material just becomes the part of magnetic circuit like this, makes Jack be in and inhales the iron state.
After sheet material is transported to the destination; Suspension ring 1 begin to descend under the effect of hoisting crane; Suspension rod 2,3 returns to state of nature under the effect of self gravitation; Contact 7 blocks so can not drive ratchet 5 rotates in the opposite direction because ratchet 5 is positioned at this moment, and Jack still is in the iron state of inhaling.When Jack continues next block plate of carrying; At first the effect lower lift ring 1 at hoisting crane rises and then 2,3 risings of drive suspension rod; Ratchet 4 promotes ratchet 5 rotations, and (positioning contact at positioning base place can block ratchet once more when ratchet 5 rotates greater than 45 °; Making Jack remain on to unload and guarantee that Jack unloads iron smoothly by the iron state) driving gear 6 drives 180 ° of the rotations of driven gear in the magnetic system once more, and at this moment magnetic is that internal upper part, bottom magnetic patch are still but opposite with axial region polarity for homopolarity; Magnetic induction line is at the inner C/LOOP that forms of magnetic system, and Jack is in the iron state that unloads.The utility model utilizes the deadweight of Jack itself to pass through mechanical drive again as propulsion source, and (gear of use all is a straight gear; Guaranteed the precision of conversion) transmission make the inner magnetic circuit of Jack make magnetic circuit closed according to different routes, and then make Jack be in to inhale the iron state or unload the iron state.
