Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace lining detection, in particular to a blast furnace lining erosion degree detection structure. Background Art

[0002] In blast furnace production, many large blast furnaces at home and abroad have experienced the phenomenon of rapid erosion of the hearth lining, which poses a serious threat to blast furnace production safety and causes huge losses and negative impacts on enterprises and society. If the thickness changes of the hearth lining in the blast furnace can be monitored in real time during the production process and the degree of erosion can be accurately grasped, the operation strategy can be adjusted in time or effective furnace protection measures can be taken to avoid further deterioration of the furnace condition and extend the life of the blast furnace.

[0003] At present, the existing blast furnace lining is mostly inspected by suspending the sonic wave detector. The suspended sonic wave detector emits sonic waves to the lining and measures the propagation speed and attenuation of the sonic waves in the lining to determine the thickness and loss of the lining. However, in actual use, the rope used for suspension is generally wrapped around the roller body. When it is recovered, human intervention is required to evenly wrap the rope around the outer wall of the roller body. Even after human intervention and adjustment, it is impossible to ensure that the rope is always evenly wrapped around the outer wall of the roller body. In actual use, due to the influence of various factors, such as the tightness of the rope, it is necessary to redesign the blast furnace lining erosion detection structure to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a blast furnace lining erosion detection structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A blast furnace lining erosion detection structure includes a frame, the outer wall of the frame is rotatably connected to a roller body, a rope is wound around the outer wall of the roller body, one end of the rope is fixedly connected to a sonic wave detector, the inner wall of the frame is rotatably connected to a reciprocating screw, a screw sleeve is threadedly connected to the threaded section of the reciprocating screw, a ring is inserted into the outer wall of the screw sleeve, the rope is inserted into the ring, and a limiting mechanism for limiting the screw sleeve is installed inside the frame.

[0007] Preferably, the limiting mechanism comprises a limiting rod fixedly connected to the inner wall of the frame, and the lead screw sleeve is slidably connected to the outer wall of the limiting rod.

[0008] Preferably, an inner wall of the frame is provided with an insertion hole, and the sleeve ring is inserted into the insertion hole.

[0009] Preferably, the outer wall of the frame body is rotatably connected with a transmission wheel 1 and a transmission wheel 2, and the transmission wheel 1 and the transmission wheel 2 are coaxially fixedly connected to the roller body and the reciprocating screw respectively.

[0010] Preferably, the transmission wheel 1 is connected to the transmission wheel 2 through a transmission belt, and the jack is located at the lower right side of the screw sleeve.

[0011] Preferably, a servo motor is fixedly connected to the outer wall of the frame, and the end of the output shaft of the servo motor is coaxially fixedly connected to the roller body.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model provides a reciprocating screw, a screw sleeve, a ring and other devices. The reciprocating screw drives the ring to slide horizontally, and the roller body rotates. During recycling, the rope can be evenly wound around the outer wall of the roller body, which reduces the situation of crossing or knotting of the rope during collection and storage, improves the efficiency of operation, and evenly winds the rope to reduce the risk of damage or wear of the rope. By maintaining uniform tension and layout, the service life of the rope can be extended.

[0014] 2. The utility model provides a ring and other devices, and by adjusting the position of the ring, it can ensure that the position of the acoustic wave detector slides in the vertical direction when it is at the bottom. This vertical sliding can improve the detection accuracy and precision of the acoustic wave detector for the target object, because when moving in the vertical direction, the distance and position information of the target object can be better detected to reduce errors. When recovering, the ring is inserted into the outer wall of the screw sleeve to ensure that the rope can be evenly wound, which can avoid the situation that the rope is crossed, knotted or unevenly wound during the recovery process, thereby improving the efficiency and stability of the operation.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 The blast furnace lining erosion detection structure includes a frame 1, the outer wall of the frame 1 is rotatably connected to a roller body 2, the outer wall of the roller body 2 is wound with a rope 3, one end of the rope 3 is fixedly connected to a sonic wave detector 4, the inner wall of the frame 1 is rotatably connected to a reciprocating screw 6, the threaded section of the reciprocating screw 6 is threadedly connected to a screw sleeve 13, the outer wall of the screw sleeve 13 is plugged with a ring 11, the rope 3 is inserted inside the ring 11, and a limiting mechanism for limiting the screw sleeve 13 is installed inside the frame 1, the limiting mechanism includes a limiting rod 7 fixedly connected to the inner wall of the frame 1, and the screw sleeve 13 is slidably connected to the outer wall of the limiting rod 7;

[0021] The reciprocating screw 6 drives the sleeve ring 11 to slide, so that the rope 3 can be evenly wound around the outer wall of the roller body 2.

[0022] Reference Figure 2 and Figure 3 The inner wall of the frame 1 is provided with a socket 12, and the ring 11 is inserted into the socket 12; when the rope 3 drives the acoustic wave detector 4 to slide downward, the set ring 11 is inserted into the socket 12, thereby ensuring that the acoustic wave detector 4 is in a horizontal vertical state when sliding down.

[0023] Reference Figure 2 and Figure 3 The outer wall of the frame body 1 is rotatably connected with a transmission wheel 1 8 and a transmission wheel 2 9. The transmission wheel 1 8 and the transmission wheel 2 9 are coaxially fixedly connected to the roller body 2 and the reciprocating screw 6 respectively. The transmission wheel 1 8 is connected to the transmission wheel 2 9 through a transmission belt 10. The socket 12 is located on the lower right side of the screw sleeve 13. The outer wall of the frame body 1 is fixedly connected with a servo motor 5. The end of the output shaft of the servo motor 5 is coaxially fixedly connected to the roller body 2. When the rope 3 is recovered, the set ring 11 is inserted into the inside of the screw sleeve 13 to ensure the uniformity of the rope 3 wrapped around the outer wall of the roller body 2.

[0024] In the utility model, the specific function of the device is as follows: when using the device, the device is placed above the furnace lining as a whole, and the roller body 2 is driven to rotate forward by means of the servo motor 5, so that the rope 3 on its outer wall drives the acoustic wave detector 4 to probe downward into the interior of the blast furnace. The acoustic wave detector 4 emits and receives acoustic waves, so that the erosion degree inside the furnace lining can be detected. When the acoustic wave detector 4 is recovered, the ring 11 sleeved on the outer wall of the rope 3 is inserted into the outer wall of the screw sleeve 13, and the roller body 2 is driven to reverse by the servo motor 5. The transmission wheel 1 8 and the transmission wheel 2 9 are arranged in coordination, and the reciprocating screw 6 can be synchronously driven to rotate, and then the screw sleeve 13 on its threaded section drives the ring 11 to slide back and forth along the outer wall of the limit rod 7. During the sliding, the rope 3 can be evenly wound around the outer wall of the roller body 2 in coordination with the reversal of the roller body 2, so that the rope 3 can be reduced from crossing or knotting during the collection and storage process, thereby improving the efficiency of the operation. At the same time, evenly winding the rope 3 can reduce the risk of damage or wear of the rope 3, and the service life of the rope 3 can be extended by maintaining uniform tension and layout.
