Description
Technical Field
The utility model belongs to the field of ferrous metallurgy and production automation, and particularly relates to a mechanical limiting device for a capping robot telescopic arm of a metal mixer.
Background
The currently implemented low-carbon environment-friendly policy puts higher demands on all links of the iron and steel enterprises. In the process of transporting molten iron, the sidecar is transported in an open way, so that a large amount of smoke dust is generated. The smoke dust causes serious pollution to the environment, and further endangers the health of people. Open transportation also results in a reduction in the temperature of the hot metal, producing an immeasurable loss in energy. When the heat loss of the molten iron reaches 150-180 degrees, normal production operation can be seriously affected, the production efficiency is reduced, the economic cost is increased, and the manpower resource is wasted. In recent years, most of large-scale steelworks in China use a mixing car to transport molten iron. Because the hot metal is carried by the hot metal mixer car, the defect of slag bonding at the furnace mouth exists. In addition, potential safety hazards such as tipping and the like exist. Because of the large number of torches Kuang Shouxian, individual businesses have failed to perform capping attempts. So users have cautious and sighted situation for using the cover of the metal mixer and have low universal acceptance.
Aiming at the pain points of the users and the actual situation, the Baowu heavy industry Co., ltd actively carries out technical research and development, and successfully develops the capping robot of the metal mixer. The device can effectively reduce the discharge amount of dust and smoke in the tank body of the metal mixer, reduce the temperature loss of molten iron, reduce the steelmaking cost and realize the functions of automatic capping and uncapping. However, the electronic limit has high failure rate in high-temperature and low-temperature environments, so that the universality is not strong.

Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.
As shown in fig. 1, a mechanical limiting device 10 of a telescopic arm 12 of a capping robot of a torpedo car of the present application comprises: the motor 11 and the screw thread pass through the screw 14 inside the telescopic arm 12. The screw 14 is used to drive the telescopic arm 12 in motion. The output end of the motor 11 is connected with one end of the coupler 15 in a matching way. The other end of the coupler 15 is connected with the screw rod 14 in a matching way. The screw 14 is provided with a support seat 16 and a nut 27 seat 17. A driving gear 18 is connected to a part of the key between the coupling 15 and the support base 16. The first bearing block 19 is fixed to the fixed arm 13 outside the telescopic arm 12 by bolts. A rotation shaft 20 is installed to penetrate through the first bearing housing 19. Intermediate gears 21 are respectively sleeved at two ends of the rotating shaft 20. An intermediate gear 21 provided at one end of the rotation shaft 20 extending into the fixed arm 13 is engaged with the driving gear 18. The fixed arm 13 is provided with a second bearing seat 24 and a third bearing seat 25. The second bearing housing 24 and the third bearing housing 25 rotatably support the screw 23. The end of the screw 23 is keyed to the driven gear 22. An intermediate gear 21 provided at one end of the rotation shaft 20 extending from the fixed arm 13 is engaged with a driven gear 22. The portion of the screw 23 between the second bearing 24 and the third bearing seat 25 is provided with a mechanical limit combination switch 26 and a stopper for triggering the mechanical limit combination switch 26. The screw 23 is further threaded between the second bearing 24 and the third bearing seat 25 with a nut 27. The stopper is slidably connected to a slide rail 28 provided to the screw 23 and fixed to the nut 27.
As a further alternative, the support base 16 is fixed to the inner side of the fixed arm 13, and rotatably supports the screw 14. The nut 27 is fixed to the end of the telescopic arm 12, and is screwed around the screw 14 to support the screw 14. The telescopic arm 12 is slidably connected to the inside of the fixed arm 13. The telescopic arm 12 slides along the inside of the fixed arm 13.
As a further scheme, the nut 27 moves linearly on the screw 23, so as to drive the limiting block to move linearly between the mechanical limit combination switches 26, thereby triggering the mechanical limit combination switches 26.
Alternatively, the driving gear 18 is at the same rotational speed as the screw 14. The driving gear 18 drives the intermediate gear 21 in meshed connection with the driving gear to rotate, and the intermediate gear 21 drives the rotating shaft 20 to rotate, so that the intermediate gear 21 at the other end of the rotating shaft 20 is driven to rotate together. The intermediate gear 21 drives the driven gear 22 meshed with the intermediate gear to rotate, the driven gear 22 drives the screw 23 to rotate, and then the nut 27 on the screw 23 is driven to do linear motion, so that a limiting block on the nut 27 triggers the mechanical limiting combination switch 26.
As a further alternative, the driving gear 18 and the intermediate gear 21 provided at the end of the rotation shaft 20 extending into the fixed arm 13 are engaged by bevel gears. The driven gear 22 and the intermediate gear 21 provided at the end of the rotation shaft 20 extending from the fixed arm 13 are engaged with each other by a bevel gear. The bevel gear can change the driving direction of the screw 14.
As a further proposal, the thread ratio of the screw rod 14 to the screw rod 23 is 6:1. This increases the rotational speed of the screw 23 and thus the speed of movement of the nut 27.
As a further alternative, the modulus ratio of the driving gear 18 to the intermediate gear 21 is 2:1. The driving gear 18 rotates once to drive the intermediate gear 21 to rotate two weeks. The modulus ratio of the driven gear 22 to the intermediate gear 21 is 2:1. The intermediate gear 21 rotates two weeks to drive the driven gear 22 to rotate one circle. This allows the stopper to move in synchronization with the telescopic arm 12, and when the telescopic arm 12 moves to a designated position, the stopper can trigger the mechanical limit combination switch 26.
As a further scheme, the limiting block is fixedly connected with the nut 27 through bolts, and the nut 27 drives the limiting block to linearly move together.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by persons skilled in the art that the above embodiments are not intended to limit the utility model in any way, and that all technical solutions obtained by means of equivalent substitutions or equivalent transformations fall within the scope of the utility model.
