Description

Technical Field

[0001] The utility model relates to the technical field of over-temperature alarm instruments, and particularly relates to a molten steel sample over-temperature alarm instrument convenient for maintenance. Background Art

[0002] In the process of automatic detection of molten steel, the whole process from sample receiving → transfer → cooling → preparation → detection → component uploading → sample filing, etc., is unmanned operation. Among them, the detection link has very high requirements for the sample temperature. If the sample temperature is too high, it will lead to inaccurate detection results.

[0003] In the prior art, a non-contact over-temperature alarm instrument is often used to detect the temperature of molten steel samples. Most of the over-temperature alarm instruments in the prior art are fixed to the device by bolts. When it is necessary to maintain the over-temperature alarm instrument, usually multiple bolts need to be loosened to maintain the over-temperature alarm instrument, and the maintenance process is relatively cumbersome and the efficiency is average.

[0025] Please refer to Figures 1-5, A molten steel sample over-temperature alarm device that is convenient for maintenance, including a device housing 1 and a mounting plate 5. A fixing block 10 is arranged on the mounting plate 5. A rotating block 11 is rotatably installed on the fixing block 10. A first T-shaped groove 16 is formed on the rotating block 11. A second T-shaped groove 17 adapted to the first T-shaped groove 16 is formed on the fixing block 10. A limiting block 8 adapted to the first T-shaped groove 16 and the second T-shaped groove 17 is arranged on the back of the device housing 1. Two symmetrically arranged fixing sleeves 9 are arranged on the back of the device housing 1. A limiting insertion rod 19 is slidably installed in the fixing sleeve 9. A return spring 18 is arranged in the fixing sleeve 9. One end of the return spring 18 is installed in the fixing sleeve 9, and the other end of the return spring 18 is installed on the limiting insertion rod 19. Two symmetrically arranged limiting insertion holes 15 are formed on the mounting plate 5. A display screen 2, a buzzer alarm 3, and a warning light 4 are arranged on the device housing 1.

[0026] Through the mutual cooperation of structures such as the rotating block 11, the limiting block 8, and the fixing block 10, when docking the device with the mounting plate 5, the first T-shaped groove 16 on the rotating block 11 can be aligned with the second T-shaped groove 17 on the fixing block 10 first. Then, the limiting block 8 is inserted into the first T-shaped groove 16 along the second T-shaped groove 17, and the device is rotated 90° so that the openings of the first T-shaped groove 16 and the second T-shaped groove 17 are staggered. At the same time, the limiting insertion rod 19 is aligned with the limiting insertion hole 15, and the return spring 18's elastic potential energy is used to push the limiting insertion rod 19 into the limiting insertion hole 15. When maintenance is required, since one end of the limiting insertion rod 19 is spherical, the device is rotated forcefully in the reverse direction, causing the spherical top of the limiting insertion rod 19 to disengage from the limiting insertion hole 15. At the same time, the openings of the first T-shaped groove 16 and the second T-shaped groove 17 are on the same axis, so that the limiting block 8 on the device can be slid out along the first T-shaped groove 16 and the second T-shaped groove 17, completing the disassembly of the device housing 1, and thus achieving the purpose of facilitating its maintenance.

[0027] Specifically, in this embodiment, four symmetrically arranged rectangular grooves 6 are formed on the mounting plate 5. Fixing bolts 7 are slidably arranged in the rectangular grooves 6.

[0028] Through the arrangement of the rectangular grooves 6 and the fixing bolts 7, it is convenient to adapt to different installation hole spacings, thus facilitating the installation of the mounting plate 5.

[0029] Specifically, in this embodiment, a rotating groove 12 is formed on the fixing block 10. The rotating block 11 is rotatably installed in the rotating groove 12. An annular groove 14 is formed on the inner wall of the rotating groove 12. A limiting ring 13 adapted to the annular groove 14 is arranged on the outer wall of the rotating block 11.

[0030] By providing structures such as the rotation groove 12 and the annular groove 14, the rotation block 11 can be rotated along the rotation groove 12, and the rotation of the rotation block 11 is restricted by the rotation of the limiting ring 13 within the annular groove 14, preventing the limiting ring 13 from disengaging from the rotation groove 12.

[0031] Specifically, in this embodiment, the cross-section of the limiting block 8 is T-shaped.

[0032] Specifically, in this embodiment, the opening end of the second T-shaped groove 17 is smaller than the diameter of the rotation block 11.

[0033] Specifically, in this embodiment, the end of the limiting insertion rod 19 away from the fixed sleeve 9 is spherical.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
