The fixed length detection device for a steel rolling mill provided in this embodiment comprises: a 9m fixed length baffle assembly 1 and a 12m fixed length baffle assembly 2 arranged between the cooling bed 6, the bottom of the 9m fixed length baffle assembly 1 and the 12m fixed length baffle assembly 2 are both provided with a lifting mechanism for lifting the 9m fixed length baffle assembly 1 and the 12m fixed length baffle assembly 2; according to the length specification of the produced steel bars, the 9m fixed length baffle assembly 1 or the 12m fixed length baffle assembly 2 is selected through the lifting mechanism; a second base 7 fixedly installed on the ground on one side of the cooling bed 6, a vertical plate 8 fixedly installed on the second base 7, and a pushing mechanism for pushing the steel on the cooling bed 6 to make one end of multiple steels aligned is provided on the vertical plate 8.

[0026] The lifting mechanism includes a first base 3, multiple lifting cylinders 4 and multiple vertical sliding rods 5. The first base 3 is arranged directly below the 9m fixed-size baffle assembly 1 and / or the 12m fixed-size baffle assembly 2. The multiple lifting cylinders 4 are fixedly installed on the top of the first base 3. The top ends of the output rods of the multiple lifting cylinders 4 are fixedly connected to the bottoms of the 9m fixed-size baffle assembly 1 and / or the 12m fixed-size baffle assembly 2.

Through the lifting mechanism, the 9m fixed-size baffle assembly 1 or the 12m fixed-size baffle assembly 2 can be selected according to the steel bar production specifications.

[0027] The pushing mechanism includes two threaded sleeves 9, two threaded rods 10, a mounting plate 11, two limit slides 12, a motor 13, two main sprockets 14, two transmission sprockets 15 and two chains 16. The two threaded sleeves 9 are rotatably mounted on the vertical plate 8. The two threaded rods 10 respectively penetrate the two threaded sleeves 9 and are respectively threadedly connected with the two threaded sleeves 9. The mounting plate 11 is fixedly mounted on one end of the two threaded rods 10. The two limit slides 12 are slidably mounted on the vertical plate 8, and one end of the two limit slides 12 is fixedly connected to one side of the mounting plate 11. The motor 13 is fixedly mounted on the top of the second base 7. The two main sprockets 14 are fixedly sleeved on the output shaft of the motor 13.

The two chains 16 are respectively meshed with the two main sprockets 14 and the two transmission sprockets 15. The pushing mechanism provides power to the movement of the steel bars to move the steel bars.

[0028] A plurality of mounting rods 23 are also slidably mounted on the mounting plate 11, and a same push plate 25 is fixedly mounted on one end of the plurality of mounting rods 23. The push plate 25 and the bottom of the mounting plate 11 are both in a sawtooth shape adapted to the top of the cooling bed 6. A limiting block is fixedly mounted on one end of the plurality of mounting rods 23, and a compression spring 24 is slidably sleeved on the plurality of mounting rods 23, so that the push plate 25 pushes the steel bar under the elastic force of the compression spring 24 to move the steel bar.

[0029] A retaining ring block 17 is fixedly mounted on each of the two limit slide bars 12, and two trigger switches 18 are fixedly mounted on one side of the vertical plate 8 close to the retaining ring block 17. The positions of the two trigger switches 18 correspond one-to-one to the two retaining ring blocks 17, and when the retaining ring block 17 resists the trigger switch 18, the equipment can shut down the operation of the motor 13.

[0030] The 9m fixed-length baffle assembly 1 and the 12m fixed-length baffle assembly 2 are both composed of a baffle body 26, a plurality of pressure sensors 27 and a force plate 28. The bottom of the baffle body 26 is fixedly connected to the top of the output rod of the lifting cylinder 4, and the baffle body 26 is slidably connected to the vertical slide rod 5. The plurality of pressure sensors 27 are embedded on one side of the baffle body 26, and the force plate 28 is fixedly installed on the force-bearing surfaces of the plurality of pressure sensors 27. The pressure sensor 27 is provided to monitor the pressure value generated by the steel bar against the force plate 28, thereby determining whether the length of the steel bar is abnormal.

[0031] The vertical plate 8 is also provided with a pulling mechanism for providing an upward pulling force to the mounting plate 11, and the pulling mechanism includes a track seat 19, a double-wheeled moving wheel 20, a connecting block 21 and two steel wire ropes 22. The track seat 19 is fixedly mounted on the top of the vertical plate 8, and the double-wheeled moving wheel 20 is rollingly mounted in two track grooves opened on the track seat 19.

The two steel wire ropes 22 are fixedly connected to the bottom of the connecting block 21, and the bottom ends of the two steel wire ropes 22 are fixedly connected to the top of the mounting plate 11.

[0032] Since the cooling bed 6 used in the steel rolling mill is relatively wide, the mounting plate 11 and the push plate 25 used in the present device are relatively long, resulting in a heavier mass. During the movement of the mounting plate 11, the double-wheeled moving wheel 20 can roll in the track groove on the track seat 19 through the steel wire rope 22 and the connecting block 21, so that the mounting plate 11 is always pulled to ensure the stability and safety of the moving process of the mounting plate 11.

[0033] It is worth noting that the circuits, electronic components and modules involved in the present utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present utility model does not involve improvements to software and methods.

[0034] The working principle of the fixed length detection device for steel rolling mills provided in this embodiment is as follows:

[0035] The present solution also has a controller, which is arranged on the device. When in use, each electrical device can be started to operate by the controller. The power connection method of each electrical device is an existing mature technology, which is a well-known technology for those skilled in the art and will not be described in detail here.

[0036] The device is also provided with an alarm, which is used to sound an alarm when abnormal steel bar specifications are detected;

[0037] When in use, when producing 9m-sized steel bars, the 9m-sized baffle assembly 1 is raised to the cooling bed 6 by starting multiple lifting cylinders 4 at the bottom of the 9m-sized baffle assembly 1;

[0038] After the batch of steel bars are translated onto the cooling bed 6, the motor 13 is started to make the two threaded sleeves 9 move synchronously, so that the two threaded rods 10 drive the mounting plate 11 to move, and the mounting plate 11 drives the push plate 25 through the mounting rod 23 and the compression spring 24 to push the steel bars on the cooling bed 6. During the pushing process, the end of the steel bar that contacts the push plate 25 is aligned. When the retaining ring block 17 on the limit slide bar 12 abuts against the trigger switch 18, the trigger controller stops the operation of the motor 13 and stops pushing the steel bars. If the steel bar just abuts against the force plate 28 and does not cause the pressure value monitored by the pressure sensor 27 to change within the set range, it means that the steel bars of this batch are just 9m (within the allowable error range);

[0039] If the value monitored by the pressure sensor 27 is almost zero, it means that the length of the steel bar is abnormal (the length of the steel bar is too short), which may be a malfunction of the length-fixing machine. In this case, the controller will shut down the operation of the steel moving machine and the shearing machine, and at the same time, the alarm will sound to remind the scrap rejector to inspect and repair the length-fixing machine.

[0040] If the pressure value monitored by the pressure sensor 27 is too large and exceeds the set range, it means that the length of the steel bar is abnormal (the length of the steel bar is too long), then the controller will shut down the operation of the steel moving machine and the shearing machine, and at the same time, the alarm will sound to remind the scrap picker to handle it;

[0041] In this way, the scrap workers can react in a short time, reducing the amount of scrapped steel bars and minimizing losses;

[0042] When producing 12m steel bars, the 12m fixed-length baffle assembly 2 is raised, and the 9m fixed-length baffle assembly 1 is in the initial state, and the above steps can be followed;

[0043] It should be noted that, in the process of pushing the steel bar by the push plate 25 , the shortening distance of the compression spring 24 is within 0.5 cm, and the stiffness coefficient of each compression spring 24 is above 200 N / cm.

[0044] In summary, the fixed length detection device provided by the utility model has the following beneficial effects:

[0045] The utility model provides a cut-to-length detection device. By arranging a 9m cut-to-length baffle assembly 1 and a 12m cut-to-length baffle assembly 2 and a lifting mechanism, the devices can be selected and used according to the specifications of the produced steel bars. By arranging a pushing mechanism on a vertical plate 8 and arranging a mounting rod 23, a compression spring 24 and a push plate 25 on a mounting plate 11, the steel bars on a cooling bed 6 can be pushed to make one end of a plurality of steel bars aligned. In combination with the 9m cut-to-length baffle assembly 1 and the 12m cut-to-length baffle assembly 2, when a cut-to-length machine fails and causes an abnormal cut-to-length length of the steel bars, a shearing machine and a steel moving machine can be shut down in time, and an alarm can be sounded for the scrapping worker to remind him to handle the problem in time, thereby ensuring that the cut-to-length length is controlled, thereby reducing the number of scrapped steel bars and reducing losses.

[0046] It should be noted that the equipment structure and drawings of the utility model mainly describe the principle of the utility model. In terms of the technology of the design principle, the settings of the power mechanism, power supply system and control system of the device are not fully described. However, on the premise that technical personnel in this field understand the principle of the above-mentioned utility model, they can clearly know the details of its power mechanism, power supply system and control system.
