Description

Technical Field

[0001] This utility model relates to a protective device for a continuous casting sector encoder, belonging to the technical field of metallurgical equipment in the metallurgical industry. Background Technology

[0002] In the 1580ESP headless hot-rolled coil production line, the continuous casting sector section is equipped with two outer arc drive rollers. These drive rollers are equipped with encoders to ensure synchronous data transmission between the rolling speed of the hot-rolled coil production line and the billet casting speed of the continuous casting machine. The design uses a through-shaft rigid connection, therefore requiring the encoder installation accuracy and the through-shaft error between the encoder and the drive roller to not exceed 0.03 mm. Replacing the encoder-equipped sector section requires repeated adjustments using dial indicators to meet production demands. Furthermore, accidental collisions during production necessitate readjustment, which is not only time-consuming and labor-intensive but also severely impacts production output. Utility Model Content

[0003] The purpose of this invention is to provide a protective device for a continuous casting sector encoder, which can improve the installation accuracy of the encoder, shorten the maintenance time of the encoder, and solve the problems existing in the background art.

[0004] The technical solution of this utility model is:

[0005] A protective device for a continuously cast sector encoder includes an encoder protective box, an encoder, a compressed air positive pressure protection interface, a universal coupling, and a protective cover. The encoder protective box is installed on the outside of the encoder, and the encoder protective box is provided with a compressed air positive pressure protection interface. One end of the encoder inside the encoder protective box is driven and connected to the universal coupling, and the universal coupling is provided with a protective cover on its outside.

[0006] The protective cover has several vent holes on its surface.

[0007] The protective cover is fixedly connected to the encoder protective box.

[0008] The encoder protective box is fixedly connected to a galvanized square tube at its lower end, and the galvanized square tube is equipped with a pipe clamp.

[0009] The beneficial effects of this utility model are as follows: a protective cover is used to connect the universal coupling to the encoder protective box, and dry compressed air is introduced into the encoder protective box to form an internal positive pressure environment to isolate steam corrosion. In addition, pipe clamps are installed on the sector-shaped section of the lifting shaft, and galvanized square tubes are welded firmly to the bottom plate of the encoder protective box to fix the encoder and prevent it from rotating with the drive roller, which would reduce the accuracy of the data.

[0013] The present invention will be further described below with reference to the accompanying drawings and examples.

[0014] See attached document Figure 1-2 A protective device for a continuous casting sector encoder includes an encoder protective box 1, an encoder 2, a compressed air positive pressure protection interface 3, a universal coupling 6, and a protective cover 8. The encoder protective box 1 is installed on the outside of the encoder 2. The encoder protective box 1 is provided with a compressed air positive pressure protection interface 3. One end of the encoder 2 inside the encoder protective box 1 is connected to the universal coupling 6. The protective cover 8 is provided on the outside of the universal coupling 6.

[0015] In this example, refer to the appendix. Figure 1-2 A protective device for a continuously cast sector-shaped encoder includes an encoder protective box 1, an encoder 2, a compressed air positive pressure protection interface 3, a pipe clamp 4, a galvanized square tube 5, a universal coupling 6, an exhaust port 7, and a protective cover 8, wherein:

[0016] Pipe clamp 4 is a 160 aluminum-plastic pipe clamp, galvanized square tube 5 is 100*50*4 in size, universal coupling 6 is a WSP type universal coupling, and protective cover 8 is a PVC protective cover with several vent holes 7 on its surface.

[0017] An encoder protective box 1 is fixedly installed on the outside of the encoder 2. A compressed air positive pressure protection interface 3 is fixedly installed on one side of the encoder protective box 1. A WSP type universal coupling is driven at one end of the encoder 2. The WSP type universal coupling is connected to the sector segment drive roller 9. A PVC protective cover that matches the WSP type universal coupling is fixedly installed on one side of the encoder protective box 1. The lower end of the encoder protective box 1 is fixedly connected to an aluminum-plastic pipe clamp through a galvanized square tube 5.

[0018] The working principle is as follows:

[0019] See attached document Figure 1 , 2 During installation and use, the through shaft in the hard connection in the background technology is cut off, and a long shaft head of φ10*25 mm is machined. At the same time, a keyway with a depth of 2 mm, a width of 3 mm, and a length of 20 mm is milled to install the WSP type universal coupling, thereby changing the original hard connection method to the soft connection method of the universal coupling.

[0020] To protect the encoder 2 and universal coupling 6 from steam corrosion in the secondary cooling chamber, this invention uses a PVC protective cover to connect the universal coupling 6 to the encoder protective housing 1. Dry compressed air is introduced into the encoder protective housing 1 to create an internal positive pressure environment, thus isolating it from steam corrosion. Furthermore, a φ160 aluminum-plastic pipe clamp is installed on the fan-shaped section of the lifting shaft, and a 100*50*4 galvanized square tube 5 is welded securely to the base plate of the encoder protective housing 1 to fix the encoder and prevent it from rotating with the drive roller, which could reduce data accuracy. These improvements not only enhance equipment accuracy but also shorten maintenance time, thereby increasing production output.
