Abstract

The utility model relates to a double-arm ejector rod hoisting permanent magnet which mainly consists of a top plate, magnetic poles, a rotation arm, a pawl, a ratchet, a cam, a hoisting support, a guide sleeve and an ejector rod. The double-arm ejector rod hoisting permanent magnet is mainly characterized in that the rotation arm drives the ejector rod to force a steel plate to leave the suction surface thereof to realize unloading. The double-arm ejector rod hoisting permanent magnet provided by the utility model is simple in structure and convenient to use.

Description

Both arms push rod hoisting permanent magnet
Technical field
The utility model relates to a kind of hoisting permanent magnet, particularly a kind of both arms push rod hoisting permanent magnet.
Background technology
At present, the iron and steel haulage equipment that is widely used has lifting electromagnet, electric control permanent magnet, hoisting permanent magnet etc., lifting electromagnet is the most frequently used a kind of, it uses the electromagnetic conversion principle, have characteristics simple in structure, that magnetic force is large, but need the corollary equipments such as electromagnetic control cabinet, productive costs is high, and power consumption is large.Electric control permanent magnet needs power consumption equally, and technology is immature can not produce large tonnage product.Although hoisting permanent magnet not power consumption also can demagnetize, because the magnetic circuit of permanent magnet needs to change, complicated mechanism, working accuracy is high, causes productive costs high, and product charge is expensive, and it is large to promote difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of hoisting permanent magnet, particularly a kind of both arms push rod hoisting permanent magnet.
The technical solution of the utility model is: a kind of both arms push rod hoisting permanent magnet, comprise magnetic pole, non-magnetic baffle plate and top board, and all magnetic poles are welded on the baffle plate, are permanent magnets between magnetic pole and the magnetic pole, and top board covers permanent magnets and magnetic pole, consists of a sucker; It is characterized in that: be provided with the lifting bearing at the two ends of top board; Be provided with main shaft at the lifting bearing; Main shaft is provided with swivel arm, ratchet and cam; Swivel arm and ratchet are arranged on the middle part of main shaft, and cam is arranged on the two ends of main shaft; Below cam, be provided with push rod; Push rod is arranged in the orienting sleeve, and orienting sleeve is arranged on the baffle plate at top board two ends; Be provided with ratchet at swivel arm, be complementary with ratchet on the main shaft.
Lifting bearing described in the utility model, main shaft, swivel arm, ratchet, ratchet, cam, orienting sleeve, push rod are and are symmetrical arranged.
The utility model is provided with the push rod roller between cam and push rod.
Ratchet of the present utility model and cam all are connected with main shaft by key.
The utility model is simple in structure, easy to operate, when suspension hook by the cam on swivel arm and the pawl ratchet rotating spindle, when making the groove of cam and push rod roller contact, be the lifting state, when rotating cam again, the convex surface of cam forces the push rod down sliding, steel plate can be backed down, make it break away to inhale the magnetic scope and unload.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, swivel arm bearing pin; 2, top board; 3, swivel arm; 4, ratchet bearing pin; 5, ratchet; 6, ratchet; 7, cam; 8, push rod roller; 9, roller bearing pin; 10, lifting bearing; 11, orienting sleeve; 12, push rod; 13, magnetic pole; 14, main shaft; 15, baffle plate.
The specific embodiment
As shown in Figure 1, the utility model is comprised of swivel arm bearing pin 1, top board 2, swivel arm 3, ratchet bearing pin 4, ratchet 5, ratchet 6, cam 7, push rod roller 8, roller bearing pin 9, lifting bearing 10, orienting sleeve 11, push rod 12, magnetic pole 13, main shaft 14, baffle plate 15; The magnetic pole 13 that is made of permanent magnets is arranged in the top board 2.Lifting bearing 10 is fixedly installed on the middle part at the two ends of top board 2, on the lifting bearing 10 main shaft 14 is set, and the middle part of main shaft 14 arranges ratchet 6, and cam 7 is installed respectively at the two ends of main shaft 14.One end of swivel arm 3 is connected with main shaft; By ratchet bearing pin 4 ratchet 5 is installed at swivel arm 3, ratchet 5 is complementary with ratchet 6; The below corresponding with cam 7 is provided with push rod roller 8 and contacts with push rod 12 in the orienting sleeve 11.Orienting sleeve 11 is fixed on the baffle plate 15 of both ends of the surface of top board 2.The tail end of swivel arm 3 is provided with swivel arm bearing pin 1.
Mode of operation of the present utility model is: rotate arm axle two and connect two chains, two chains are connected with suspension ring.Travelling crane hook hangs in the suspension ring, when driving is upwards started, driving two swivel arms rotates, ratchet on the swivel arm drives the ratchet rotation, because ratchet and cam and main shaft all are key connecting, so by the rotation of ratchet band moving cam, the push rod upward sliding is to the groove of cam, be the suction magnetic state this moment, but the lifting steel plate.As will unload lower steel plate the time, swivel arm is put down fully, after putting down fully with swivel arm, withstands on ratchet on the swivel arm another tooth of ratchet, then risen by driving and drive upwards rotation of swivel arm, so cam rotates to an angle, push up the bar that bears down on one by cam by roller, make the push rod down sliding, push rod makes the suction surface of hoisting permanent magnet break away from steel plate and unload magnetic with regard to having backed down steel plate like this.So repeatedly can suction and discharging.
