Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace measurement, and specifically refers to a blast furnace sounding rod device. Background Art

[0002] A blast furnace sounding rod is a device for monitoring the material level inside a blast furnace during the ironmaking production process. It is driven by a motor to move a heavy hammer along with the movement of the ore or coke surface inside the blast furnace to detect the height and distribution of the furnace charge, and feeds back the measured data information to the blast furnace operator.

[0003] The patent with the publication number CN210826228U discloses a blast furnace sounding rod with stable descent. By setting an annular plate, chain holes and elastic members, the position of the chain can be limited, avoiding too large a distance between the chain holes and the chain, resulting in too large a swing amplitude of the heavy hammer during descent. Narrowing the distance between the chain holes and the chain can effectively reduce the swing amplitude, ensure that the heavy hammer descends more smoothly, avoid the heavy hammer hitting the inner wall of the blast furnace, and extend the service life of the sounding rod.

[0004] However, when the above device is in use, since the arc-shaped plate is in direct contact with the outer wall of the chain, the chain rubs against the arc-shaped plate during the lifting and lowering movement, which easily accelerates the wear of the chain and reduces the service life of the chain. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that when the existing equipment limits the chain, it is easy to directly rub against the chain, accelerating the wear of the chain and reducing the service life of the equipment.

[0006] To achieve the above functions, the technical solution adopted by the utility model is as follows: a blast furnace sounding rod device, including a mounting plate, and further including a guiding and limiting mechanism and a driving and winding mechanism arranged on the mounting plate; the guiding and limiting mechanism includes a conduit and an annular plate, the conduit is arranged through the mounting plate, springs are arranged on the side wall of the conduit, multiple groups of springs are symmetrically arranged, the annular plate is arranged between the multiple groups of springs, and a limiting component is arranged on the annular plate.

[0007] Further, the limiting component includes a connecting rod and a limiting ring, the connecting rods are evenly distributed on the inner wall of the annular plate, the limiting ring is arranged on the multiple groups of connecting rods, and a rolling ring is rotatably arranged on the limiting ring.

[0008] Further, the driving and winding mechanism includes a motor and a reducer, the motor and the reducer are both arranged on the mounting plate, the output end of the motor is connected to the reducer, a transmission shaft is connected to the reducer, a winding roller is connected to the end of the transmission shaft, a chain is wound on the winding roller, and a heavy hammer is arranged at the end of the chain.

[0009] Furthermore, the winding roller is rotatably arranged in the conduit, and the chain passes through the limiting ring and is placed between multiple groups of the rolling rings.

[0010] Preferably, multiple groups of the rolling rings are densely arranged.

[0011] The beneficial effects of the present utility model adopting the above structure are as follows: A blast furnace sounding rod device provided by the present utility model restricts the movement of the chain by setting the limiting ring. At the same time, by using the rolling rings, direct friction between the chain and the limiting ring is avoided during the movement of the chain, reducing the frictional loss of the chain, thereby increasing the service life of the chain. At the same time, by using the spring and the annular plate, the chain can be buffered during the offset process, reducing the swaying amplitude of the chain, thereby maintaining the stable state of the chain and facilitating the stable lifting and lowering of the plumb bob.

Specific Embodiment

[0016] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following further describes the present utility model in detail with reference to the drawings.

[0018] As Figures 1-3 shown, a blast furnace sounding rod device proposed by the present utility model includes a mounting plate 1, and further includes a guiding and limiting mechanism 2 and a driving and winding mechanism 3 provided on the mounting plate 1; the guiding and limiting mechanism 2 includes a conduit 4 and an annular plate 5. The conduit 4 is penetrated and arranged on the mounting plate 1. Springs 6 are provided on the side wall of the conduit 4, and multiple groups of springs 6 are symmetrically arranged. The annular plate 5 is arranged between multiple groups of springs 6. A limiting component 7 is provided on the annular plate 5. After the driving and winding mechanism 3 is started, the annular plate 5 is forced to squeeze the springs 6, so that the springs 6 push the annular plate 5 to reset in the reverse direction, which can provide a certain buffering effect, avoid large-amplitude shaking, and improve the accuracy of detection.

[0019] As Figure 3 shown, the limiting component 7 includes a connecting rod 8 and a limiting ring 9. The connecting rods 8 are evenly distributed on the inner wall of the annular plate 5. The limiting ring 9 is arranged on multiple groups of connecting rods 8. A rolling ring 10 is rotatably arranged on the limiting ring 9. Multiple groups of rolling rings 10 are densely arranged. The rolling ring 10 rotates under force, which can provide protection for the limiting ring 9, reduce friction loss, and extend the service life of the equipment.

[0020] As Figure 2 shown, the driving and winding mechanism 3 includes a motor 11 and a reducer 12. The motor 11 and the reducer 12 are both arranged on the mounting plate 1. The output end of the motor 11 is connected to the reducer 12. A transmission shaft 13 is connected to the reducer 12. A winding roller 14 is connected to the end of the transmission shaft 13. The winding roller 14 is rotatably arranged in the conduit 4. A chain 15 is wound around the winding roller 14. The chain 15 penetrates through the limiting ring 9 and is placed between multiple groups of rolling rings 10. A weight 16 is provided at the end of the chain 15. The driving motor 11 adjusts the rotation speed through the reducer 12 to drive the winding roller 14 to wind and unwind, so as to drive the chain 15 to move. After the chain 15 passes through the limiting ring, it is restricted by the limiting ring 9. At the same time, in cooperation with the springs 6 and the annular plate 5, large-amplitude shaking is avoided. The chain 15 is in rolling contact with the rolling rings 10, avoiding direct contact and friction with the limiting ring 9, thereby reducing the friction loss between the chain 15 and the limiting ring 9 and extending the service life of the equipment.

[0021] The above description is about the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
