As an embodiment of the present invention, referring to fig. 2, 7 and 8, a connecting structure capable of being connected with a speed reduction motor 16 is fixedly installed at each end of two transmission shafts 12, the connecting structure includes a first chuck 25 fixedly installed at each end of the two transmission shafts 12, two square grooves 24 are respectively installed on the first chuck 25, springs 22 are respectively fixedly installed in the four square grooves 24, a clamping strip 21 is respectively fixedly connected at each end of the four springs 22, a second chuck 14 is fixedly installed on the speed reduction motor 16, the positions of the second chuck 14 and the first chuck 25 correspond to each other, two circular grooves 20 are respectively installed on the second chuck 14, the four circular grooves 20 are respectively matched with the four clamping strips 21, and a clamping device capable of clamping the oven door 1 is fixed on the fixing block 2.
When the oven door 1 moves up and down, the hanging chain 13 mainly bears the gravity of the oven door 1, the transmission shaft 12 drives the hanging chain 13 to realize the up-and-down movement of the oven door 1, the hanging chain 13 is transmitted under the long-time load, the abrasion is only more serious, if the sudden situation occurs, when the hanging chain 13 on one side is suddenly broken, the load bearing of the hanging chain 13 on the other side is suddenly increased, the load transmitted by the transmission shaft 12 is also suddenly increased, the load force borne by a chuck I25 connected with the transmission shaft 12 is also correspondingly increased, when the load is overweight, the increased gravity is pressed on the transmission shaft 12, the rotating speed of the transmission shaft 12 and a corresponding speed reducing motor 16 has a certain rotating difference, the rotating difference can cause the matching failure between the chuck I25 and the chuck II 14, a clamping strip 21 connected with a spring 22 is forcibly disconnected from a round groove 20, so that the transmission shaft 12 is disconnected with the speed reducing motor 16, the transmission shaft 12 stops rotating to prevent the other end of the well-finished sling chain 13 from continuing to work, so that the situation that the furnace door 1 shakes is avoided, and a relatively balanced state is achieved.
Referring to fig. 7, as an embodiment of the present invention, the locking device includes a mounting block 9 fixedly mounted on the fixed block 2, an electric push rod 18 fixedly mounted at one end inside the mounting block 9, a locking block 19 fixedly mounted at a pushing end of the electric push rod 18, and the electric push rod 18 and the proximity switch 15 are electrically connected.
Once the chuck I25 and the chuck II 14 are disconnected, the situation that the hanging chain 13 for bearing the furnace door 1 is broken and overloaded is meant, if the furnace door 1 falls off under the situation that high-temperature objects are discharged, the discharged objects can be smashed, splashes possibly exist on the smashed high-temperature objects, if people are nearby, the high-temperature splashes possibly injure the high-temperature objects, in order to avoid the situation, a clamping device is arranged on the fixed block 2 and needs to be manually started, after the high-temperature objects are started, the electric push rod 18 immediately pushes the clamping block 19 out at the moment of receiving a signal, the clamping block passes through the pulley 3 and stretches into the bent slide rail 4 to be clamped, and the clamping block 19 is clamped among the fixed block 2, the pulley 3 and the bent slide rail 4 to temporarily clamp the furnace door 1 to prevent the furnace door from sliding down, so that the safety performance is greatly improved.
Referring to fig. 2 and 6, as an embodiment of the present invention, a proximity switch 15 is fixedly mounted on one side of the chuck one 25, and the proximity switch 15 is electrically connected to the electric push rod 18.
At the moment of overload, the card strip 21 connected with the spring 22 is forcibly torn off from the circular groove 20, at the moment of tearing off, the card strip 21 retracts under the tension of the spring 22, the card strip 21 belongs to a moving object with displacement change, the proximity switch 15 fixed on the first chuck 25 is triggered to start at the moment of sensing the displacement change of the card strip 21, and outputs a signal to the electric push rod 18, the electric push rod 18 starts to work after receiving the signal, the manual starting is avoided, and the time-saving and labor-saving effects are achieved.
Referring to fig. 7, as an embodiment of the present invention, an induction alarm 17 is fixedly installed at the other side of the first chuck 25.
When overload occurs, due to overload torque, the clamping strip 21 is forcibly disconnected from the second chuck 14, the displacement is changed in the process, the induction alarm 17 arranged at one end of the first chuck 25 is triggered and sounds an alarm when the displacement change of the clamping strip 21 is induced, after the alarm is sounded, the overload condition is already generated, if the distance between field personnel is far away, the situation of the furnace can be known after the alarm sound is heard, and the situation can be timely fed back to be processed.
Referring to fig. 6, the cartridge 19 is made of 45# steel material as an embodiment of the present invention.
The latch 19 is a thing which can abut against the oven door 1, the load to be born by the latch 19 is large, and a certain impact force is also born, so that the material of the latch 19 has great hardness and strength to bear the load, and the 45# steel is high-quality carbon structural steel, has sufficient strength and toughness, is economical and practical, and is very suitable for being used as the material of the latch 19.
The working principle is as follows: when the furnace is about to start to work, firstly, steel is conveyed into the furnace, the temperature in the furnace is at normal temperature, after the steel is conveyed into the furnace, a speed reducing motor 16 is started, a hanging chain 13 for controlling the movement of the furnace door 1 starts to operate, a pulley 3 on the furnace door 1 is matched with a curved slide rail 4, the furnace door 1 can slide downwards more smoothly by virtue of the weight of the furnace door 1, when the furnace door 1 is about to slide to the lower part of the curved slide rail 4, the furnace door 1 can slide to an opening along a curved path of the curved slide rail 4 until the furnace door 1 is covered with the opening, when the furnace door 1 slides to the covered part, the pulley 3 also slides to the bottom of the curved slide rail 4, a limit switch 8 positioned at the bottom of the curved slide rail 4 is triggered when the pulley 3 slides to the bottom, after the limit switch 8 is triggered, a hydraulic cylinder 5 matched with the limit switch starts to work, an extending end of the hydraulic cylinder 5 starts to push a long block 6 to move, the push rod 7 on the long block 6 gradually approaches to the groove 23 on the bracket 11 until the push rod 7 is matched with the groove 23, because the furnace door 1 is in a frustum pyramid shape, the frustum pyramid-shaped furnace door 1 is more easily extruded and attached to the opening in the matching process of the push rod 7 and the groove 23, when the furnace finishes working, the electric button 10 is pressed, the hydraulic cylinder 5 on the furnace door 1 drives the push rod 7 to retract, the hanging chain 13 drives the furnace door 1 to slide upwards, the furnace door 1 stops when sliding to the top end of the curved sliding rail 4, in consideration of emergency situations, when the hanging chain 13 breaks, the load is increased, the matching of the first chuck 25 and the second chuck 14 is broken, so that the transmission between the transmission shaft 12 and the speed reducing motor 16 is blocked, the first chuck 25 and the second chuck 14 are separated, the induction alarm 17 is triggered to sound an alarm, and meanwhile, the proximity switch 15 is also triggered, the electric push rod 18 matched with the proximity switch 15 is started, the electric push rod 18 immediately pushes the clamping block 19 out to clamp the furnace door 1, so that the furnace door is prevented from sliding and waits for the treatment of workers.
