Description

Technical Field

[0001] This utility model relates to the technical field of continuous casting machines, and in particular to an anti-derailment chain wheel device for continuous casting machines. Background Technology

[0002] In actual continuous casting machine production, frequent roller rotation can cause the sprocket retaining ring fixing bolts to loosen or fall off, and even cause the sprocket to detach from the roller shaft. After the sprocket shifts or falls off, the chain falls off, causing the entire roller transmission system to malfunction, the billet to stop moving, and accidents to occur. If the above problems occur, it is necessary to contact the production scheduler to coordinate the flow blockage and stop the machine, and reinstall the sprocket, which seriously restricts production organization. Currently, the sprocket retaining ring is usually fixed by a single bolt, which is very easy to loosen during the rotation of the roller shaft, affecting work efficiency. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Please see Figures 1 to 6 The present invention discloses an anti-derailment chain wheel device for a continuous casting machine, comprising a rotating roller shaft 100, a retaining ring 110, a bolt fixing assembly 200, an anti-loosening assembly 300, and a warning assembly 400. The retaining ring 110 is disposed on the side of the rotating roller shaft 100, the bolt fixing assembly 200 connects the retaining ring 110 and the rotating roller shaft 100, the anti-loosening assembly 300 is disposed on the side of the retaining ring 110, and the warning assembly 400 is disposed on the anti-loosening assembly 300.

[0027] Among them, the bolt fixing component 200 serves to fix the retaining ring 110, the anti-loosening component 300 reduces the possibility of the bolt fixing component 200 loosening, and the warning component 400 serves to alarm and remind.

[0028] Furthermore, when a user uses the anti-derailment chain wheel device on a continuous casting machine according to this utility model, the user first sets the retaining ring 110 on the side of the rotating roller shaft 100, then sets the anti-loosening component 300 on the retaining ring 110, and then the user tightens the bolt fixing component 200 to fix the retaining ring 110 on the rotating roller shaft 100. After the rotating roller shaft 100 rotates for a period of time, if the bolt fixing component 200 becomes loose, the warning component 400 will work to issue an alarm indication. The user can retighten the bolt fixing component 200 according to the alarm indication issued by the warning component 400.

[0029] In this embodiment, the bolt fixing assembly 200 includes: a first fastening bolt 210 and a second fastening bolt 220. The first fastening bolt 210 and the second fastening bolt 220 connect the retaining ring 110 and the rotating roller shaft 100. The first fastening bolt 210 is located on the left side of the retaining ring 110, and the second fastening bolt 220 is located on the right side of the retaining ring 110. A first contact guide post 211 is provided at the bottom of the first fastening bolt 210, and a second contact guide post 221 is provided at the bottom of the second fastening bolt 220. The anti-loosening assembly 300 includes: an anti-loosening plate 310, a connecting block 320, a fastening block 330, a first fastening groove 340, and a spring 350. The anti-loosening plate 310 is located on the side of the retaining ring 110, and the connecting block 320 is located below the anti-loosening plate 310. The side of the rotating roller 100 is provided with a first fastening groove 340. The spring 350 and the fastening block 330 are disposed in the first fastening groove 340. One end of the spring 350 is connected to the inner wall of the first fastening groove 340, and the other end of the spring 350 is connected to the fastening block 330. The side of the rotating roller 100 is provided with a first threaded hole 101 and a second threaded hole 102. A first contact detector 103 is provided at the bottom of the first threaded hole 101, and a second contact detector 104 is provided at the bottom of the second threaded hole 102. The first contact detector 103 is electrically connected to the first detection receiver 410, and the second contact detector 104 is electrically connected to the second detection receiver 420. The retaining ring 110 is provided with a mounting groove 111, and the inner walls of the mounting groove 111 are provided with second fastening grooves 112 on both sides.

[0030] When the user needs to fasten the retaining ring 110 to the side of the rotating roller shaft 100, firstly, the fastening block 330 is pressed into the first fastening groove 340. Then, the connecting block 320 is placed into the mounting groove 111. Moving the connecting block 320, when the fastening block 330 moves to the position of the second fastening groove 112, the spring 350 changes from a compressed state to an extended state, causing the fastening block 330 to spring into the second fastening groove 112. At this time, the anti-loosening plate 310 moves to the position contacting the surface of the retaining ring 110. Then, the user screws the first fastening bolt 210 into the first threaded hole 101 and the second fastening bolt 220 into the second threaded hole 102. The retaining ring 110 is fixed to the side of the rotating roller shaft 100 by the first fastening bolt 210 and the second fastening bolt 220. At this time, the first contact guide post 211 on the first fastening bolt 210 contacts the first contact detector 103 at the bottom of the first threaded hole 101, and the second contact guide post 221 on the second fastening bolt 220 contacts the second contact detector 104 at the bottom of the second threaded hole 102. When the first fastening bolt 210 and the second fastening bolt 220 are tightened, the anti-loosening plate 310 is flattened and generates longitudinal elastic force, which compresses the screw threads, increases the friction, and reduces the possibility of the first fastening bolt 210 and the second fastening bolt 220 loosening. By setting the connecting block 320, fastening block 330, first fastening groove 340 and spring 350 at the bottom of the anti-loosening plate 310, it is convenient to fix the anti-loosening plate 310 to the side of the retaining ring 110, making it convenient for the user to tighten the bolt fixing assembly 200.

[0031] In this embodiment, the warning component 400 includes: a first detection receiver 410, a second detection receiver 420, a first warning light 411, and a second warning light 421. The first detection receiver 410, the second detection receiver 420, the first warning light 411, and the second warning light 421 are all disposed on the anti-loosening plate 310. The first detection receiver 410 and the first warning light 411 are electrically connected, and the second detection receiver 420 and the second warning light 421 are electrically connected.

[0032] If the first fastening bolt 210 becomes loose, the first contact guide post 211 will lose contact with the first contact detector 103, the first detection receiver 410 will not receive a contact signal, the first detection receiver 410 will issue a disconnection signal, and the first warning light 411 will flash to remind the user that the first fastening bolt 210 is loose, facilitating subsequent maintenance work and preventing accidents. Similarly, if the second fastening bolt 220 becomes loose, the second contact guide post 221 will lose contact with the second contact detector 104, the second detection receiver 420 will not receive a contact signal, the second detection receiver 420 will issue a disconnection signal, and the second warning light 421 will flash to remind the user that the second fastening bolt 220 is loose, facilitating subsequent maintenance work and preventing accidents.

[0033] This anti-detachment sprocket device for a continuous casting machine includes a rotating roller shaft 100, a retaining ring 110, a bolt fixing assembly 200, an anti-loosening assembly 300, and a warning assembly 400. The retaining ring 110 is disposed on the side of the rotating roller shaft 100. The bolt fixing assembly 200 connects the retaining ring 110 and the rotating roller shaft 100.
