When the inserted rod 5 is inserted into the limiting hole, the spring is in a free state. The upper end and the lower end of the electromagnet 6 are fixedly connected with one end of a right-angled connecting claw, and the other end of the connecting claw is fixedly connected on the pipe body 3. When the electromagnet 6 is electrified, electromagnetic attraction is generated, and the electromagnetic attraction is larger than the elastic force of the spring, so that the electromagnet 6 can pull the inserted rod 5 out of the limiting hole; when the central lines of the limiting hole and the through hole are not collinear, the electromagnet 6 is not electrified, the inserted rod 5 is propped against the rod body 4 at the moment, and the spring is in a compressed state.
When cantilever 2 is lifted to needs, telescopic machanism extends, and when spacing hole slided to the position with through-hole center collineation, under the effect of spring elasticity, inserted bar 5 can insert spacing downthehole in the twinkling of an eye, realizes the spacing to body of pipe 3 and the body of rod 4, makes telescopic machanism neither can extend, also can not contract to the realization is to cantilever 2's supporting role. When the cantilever 2 needs to fall down, the power supply of the electromagnet 6 is switched on, the electromagnet 6 attracts the inserted bar 5, so that the inserted bar 5 is pulled out from the limiting hole, and then the cantilever 2 can fall down.
The boss structure is an annular bulge and is fixedly connected to one side of the inner wall of the through hole, which is far away from the limiting hole, and the inner diameter of the boss structure is smaller than that of the through hole and larger than the outer diameter of the polished rod of the inserted link 5, so that the polished rod can penetrate through the middle part of the boss structure; the internal diameter of lug boss structure is less than the external diameter of 5 annular platforms of inserted bar, therefore the annular platform can't pass the lug boss structure, consequently can play limiting displacement to the lug boss structure, prevents that inserted bar 5 from deviating from in the through-hole. The spring is sleeved on the polished rod, and two ends of the spring respectively abut against the boss structure and the annular table, so that the spring can be installed between the inserted rod 5 and the through hole, and the spring can play an elastic role in the inserted rod 5. The separation blade is located the outside of body 3, and the separation blade also can inject the position of inserted bar 5, prevents that inserted bar 5 from inserting completely in the through-hole, and the separation blade is magnetic material, can be by 6 magnetic attraction of electro-magnet, also can increase the magnetism area of contact of electro-magnet 6 and inserted bar 5 through the separation blade, and is more firm when electro-magnet 6 and inserted bar 5 magnetism are connected.
The contact is established ties in elevating gear is in the circuit of hoist engine 9, and the circuit of hoist engine 9 includes zero line and live wire, and the two direction switch of control hoist engine 9 is established ties on the live wire of circuit, and the contact also establishes ties among the live wire circuit, and the contact is located before the two direction switch, when the inserted bar 5 inserts spacing downthehole, the contact disconnection, the circuit is in the outage state this moment, when the inserted bar 5 does not insert spacing downthehole, no matter 6 switches on of electro-magnet are not switched on, the contact all contacts, the circuit is in the on-state this moment.
When the steel ladle drawing device is used, as shown in fig. 4, at the moment, the cover 8 covers the opening of the steel ladle 7, the reversing switch of the winch 9 is in a stop station, the telescopic mechanism is in a contraction state, the inserted rod 5 is not inserted into the limiting hole, the spring is in a compression state, the contact is in a connection state, and the circuit of the winch 9 is in a communication state.
The reversing switch of the winch 9 is rotated to a lifting station, the winch 9 winds the rope, so that the rope pulls the extending section of the cantilever 2 to turn downwards by taking the hinge point as a center, and the connecting section of the cantilever 2 drives the tank cover 8 to turn upwards by taking the hinge point as a center; cantilever 1 and cantilever 2's contained angle grow this moment, because cantilever 1 and cantilever 2's length is unchangeable, consequently, the contained angle grow, telescopic machanism extends, consequently, body of rod 4 can be followed body of pipe 3 and upwards slided, consequently spacing hole can slide to with the collinear position in through-hole center, this moment under the effect of spring elasticity, inserted bar 5 can insert spacing downthehole in the twinkling of an eye, realize spacing to body of rod 3 and body of rod 4, make telescopic machanism can not extend, also can not shrink, thereby realize support and limiting displacement to cantilever 2. Meanwhile, the contact is disconnected instantly, so that the circuit of the winch 9 is powered off, the winch 9 stops working, and the rope of the winch 9 is prevented from pulling the cantilever 2 and the tank cover 8 to exceed a limited turning angle. At this moment, the working state of the utility model is as shown in fig. 5.
When the tank cover 8 needs to be put down, the reversing switch of the winch 9 is rotated to a descending station, then the electromagnet 6 is started, the magnetic attraction of the electromagnet 6 to the baffle of the inserted rod 5 overcomes the elastic force of the spring, the spring is compressed, the inserted rod 5 can be pulled out from the limiting hole, and the inserted rod 5 is enabled to release the position limitation of the pipe body 3 and the rod body 4. Meanwhile, the contacts are connected to communicate the circuit of the winch 9, so that the winch 9 can release the rope, the tank cover 8 presses the connecting section of the cantilever 2 downwards under the action of the gravity of the tank cover 8, the connecting section is turned downwards by taking the hinge point as the center, and the extending section of the cantilever 2 is turned upwards by taking the hinge point as the center. Thus, the can lid 8 can cover the opening of the ladle 7. And after the tank cover 8 covers the ladle 7, rotating the reversing switch to a stop station, thereby finishing the lifting work of the tank cover 8.
