Abstract
The gravity switched permanent-magnet attraction disc as lifting apparatus is composed of attraction disc and executing mechanism. Said attraction disc is a combined magnetic system consisting of primary and control magnetic systems. Under the drive of pivot the control magnetic system revolves around the central axle of primary one by appropriate angle to close or open the internal loop of attraction disc. Said executing mechanism is composed of bevel gear, ratchet wheel, detent and five-connecting-rod mechanism. When lifting, the attraction disc is automaticall opened or closed under action of gravity.
Description
The present invention is with the technical field of permanent magnet as the magnetic Jack of magnetic source.
From the seventies so far, people are just constantly developing various types of permanent magnetic lifters, mainly contain reversible magnetic body, the permanent magnetic lifter of hybrid and parallel-moving type of permanent-magnetism electromagnetic or rotary magnetic system, auxiliary (ac/dc) power supply of its action need or manually realize picking up/taking off putting weight, operation is very heavy, and there is the leakage field phenomenon, the magnetic energy utilization rate is low, and equipment volume is doted on greatly, costs an arm and a leg.
The objective of the invention is by gravity, sucker only needs the lifting of weight-lifting equipment can pick up/take off and puts weight.
For this reason, technical scheme of the present invention is such: the present invention is made up of sucker and actuating unit.Sucker is the combination magnetic system that is made of main magnetic system and control magnetic system.Actuating unit is by the transmission of bevel gear quadrature, and five of unidirectional transmission of click and symmetry connects mechanism and form, and rotatablely moves the On/Off sucker with what the lifter motion of weight-lifting equipment was converted into control magnetic system.
Like this, by gravity, when weight-lifting equipment promoted, making control magnetic through actuating unit was the rotation respective angles, and control magnetic system is to constitute home loop with main magnetic, and pole-face is nonpolarity, and sucker takes off puts weight; When weight-lifting equipment promoted once more, through actuating unit, making control magnetic once more was the rotation respective angles, and control magnetic system is to constitute open magnetic circuit completely with main magnetic, and sucker picks up weight.
The present invention compares with existing permanent magnetic lifter has following useful effect: the lifter motion that operation only needs weight-lifting equipment is put in picking up/taking off of sucker, and on-the-spot hoisting operation is very easy; Since adopt the screen-wall technology, the magnetic leakage free phenomenon, and the suction anharmonic ratio of unit magnetic material is very high; The magnetic source distributing position is lower, compact overall structure; The logical size of the magnetic potential/gesture of pole-face changes along with the anglec of rotation (aperture of switch) of control magnetic system.

Gravity switch type permanent-magnet attractive disk is made up of sucker 1 and actuating unit 2.Connect (Fig. 1) with connecting flange 3 between them.
Sucker 1 comprise main magnetic be 4 and control magnetic be 5 (Fig. 3).Main magnetic is 4 to be to be made of cartridge 6, screen-wall member 7 and magnetic sheet 8, and cartridge 6 is the mirror symmetric arrangement, and magnetic sheet 8 is clipped between cartridge 6 and the cartridge 6, between cartridge 6 and the screen-wall member 7, make the polarity of adjacent cartridge 6 different.Control magnetic is 5 to be to be rotating disk 4 above at main magnetic, and to be driven around main magnetic by pivot 12 be that 4 center shafts rotate.Rotating disk is to be made by non-magnetic disk 9 and the magnetic sheet 10 inlayed in it, and the position of magnetic sheet 10 and polarity and main magnetic are 4 cartridge 6 corresponding (see figure 6)s.
Actuating unit 2 comprises the five-bar mechanism 15 (Fig. 2) of bevel gear quadrature transmission 13, the unidirectional transmission 14 of click and symmetry.
The transmission 13 of bevel gear quadrature constitutes (Fig. 3) by casing 16, bevel gear 17 and gudgeon 18.Connecting flange 3 respectively with screen-wall member 7 and casing 16 bolt togethers, gudgeon 18 passes the wheel hub 19 of casing 16.Through bevel gear 17 rotatablely moving of pivot 12 is converted into rotatablely moving of both sides gudgeon 18.
The five-bar mechanism 15 of symmetry is formed (Fig. 2) by connecting rod 20,21,22,23.Connecting rod 20,21 is enclosed within respectively on the gudgeon 18 of both sides, and connecting rod 23 is connected with connecting rod 20,21 usefulness connecting rods 22.Suspension ring 28 usefulness bearing pins are connected with connecting rod 23.The outside of the otic placode 30 above link stopper 29 static housings 16.When promoting suspension ring 28, connecting rod 20,21 rotates to link stopper 29 around gudgeon 18 respectively.
The unidirectional transmission 14 of click is made up of ratchet 24 and ratchet 25 and torsion spring 26.Ratchet 24 is enclosed within on the gudgeon 18, connects with the open circles taper pin.Ratchet 25 is enclosed within on the bearing pin 27 of connecting rod 21, and torsion spring 26 is enclosed within on the shaft shoulder of bearing pin 27, and its two ends are pressed in respectively on connecting rod 21 and the ratchet 25.When promoting suspension ring 28 at every turn, a circular pitch of gudgeon 18 rotary pawls 24, the i.e. number of teeth of 360 degree/ratchets 24
The present invention is work like this: when weight-lifting equipment promoted, by gravity, the control magnetic that actuating unit 2 drives sucker 1 were 5 rotation respective angles, and making itself and main magnetic is 4 formations open circuits fully, and sucker 1 picks up weight.When weight-lifting equipment promoted once more, control magnetic was 5 to rotate respective angles once more, and sucker 1 constitutes home loop, and pole-face is nonmagnetic, takes off to put weight.
