Description

Technical Field

[0001] The utility model relates to the technical field of rolling mill protection, and particularly relates to a safety protection device for a rolling mill which is convenient to adjust. Background Technique

[0002] A rolling mill is a device for realizing the metal rolling process, generally referring to the equipment for completing the whole process of rolled product production. Rolling mills can be divided into two-high, four-high, six-high, eight-high, twelve-high, eighteen-high, etc. according to the number of rolls.

[0003] At present, an existing safety protection device for a four-high reversing rolling mill (such as patent number: CN220195938U) discloses a safety protection device for a four-high reversing rolling mill, which improves the problems that the rolling mill is prone to cause injuries and the feeding and discharging are inaccurate. When the distance between the rolls of the present application is adjusted, the adjusting plate can be driven to slide on the inner wall of the through groove, so that the guiding port can always be opposite to the processing port between the rolls, which is convenient for processing materials with different thicknesses. Moreover, the protection plate can protect the inside of the rolling mill to avoid causing injuries and improve the safety of material processing. The material can be fed and discharged through the material guiding plate, guiding roller and supporting roller, so that the material can accurately enter between the rolls for processing, improving the accuracy of material feeding and discharging and increasing the practicability of the device.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following problems: both ends of the rotating shafts of two of the rolls are fixedly connected with connecting shafts. The connecting shafts are structures for connecting power equipment. In order to protect the safety of the equipment and personnel, a protective fence will be placed beside the connection position. When the rolling mill moves, the protective fence needs to be disassembled before moving. At the same time, in order to ensure that the protective fence will not move randomly and collide with the rolling mill during the moving process, damaging the rolling mill or causing damage to personnel, the protective fence needs to be fixed or transported separately by the staff, increasing the workload of the staff.

The general idea is as follows:

[0027] In view of the problems existing in the prior art, the present utility model provides a safety protection device for a rolling mill that is easy to adjust. The safety protection device for a rolling mill that is easy to adjust includes a frame 1. Protective mechanisms are arranged on both sides of the frame 1. Each protective mechanism includes a rotating shaft 2, a protective plate 3, a receiving groove 4, a connecting plate 5, a limiting hole 6, and a limiting screw 7. The rotating shaft 2 is rotatably connected to the outside of the frame 1. The protective plate 3 is fixedly connected to the outside of the rotating shaft 2. The receiving groove 4 is opened on the side of the protective plate 3 away from the rotating shaft 2. The connecting plate 5 is slidably connected to the inside of the receiving groove 4. The limiting hole 6 is opened on the outside of the protective plate 3. The limiting hole 6 is a threaded hole and is communicated with the receiving groove 4. The limiting screw 7 is threadedly connected to the inside of the limiting hole 6, and the limiting screw 7 is in contact with the outside of the connecting plate 5. By providing the protective plate 3 and cooperating with the connecting plate 5, when using the rolling mill, after the connecting shaft is connected to the power device, at this time, rotate the protective plate 3 so that the protective plate 3 shields the connection between the connecting shaft and the power device. If the length of the protective plate 3 is not enough, at this time, rotate the limiting screw 7 so that the limiting screw 7 no longer contacts the connecting plate 5. At this time, pull the connecting plate 5 so that the length formed by the protective plate 3 and the connecting plate 5 meets the working requirements. After adjustment, rotate the limiting screw 7 so that the limiting screw 7 contacts the connecting plate 5. At this time, the connecting plate 5 is fixed. At this time, the protective plate 3 and the connecting plate 5 shield the connection position to prevent the staff from approaching the connection. When the protective plate 3 is not used, put the connecting plate 5 into the inside of the receiving groove 4. At this time, rotate the protective plate 3, and the protective plate 3 can shield the rolling rolls of the rolling mill, providing protection for the protective plate 3, facilitating the adjustment of the length formed by the protective plate 3 and the connecting plate 5 and the position of the protective plate 3 according to the actual situation. During the movement of the rolling mill, the protective mechanism moves together with the rolling mill, and there is no need to fix and transport the protective mechanism separately, reducing the workload of the staff and improving the practicability of the protective mechanism.

[0028] An internal groove 8 is opened in the inside of each receiving groove 4. An internal plate 9 is slidably connected to each internal groove 8. The internal plate 9 is fixedly installed on the outside of the protective plate 3 to prevent the connection between the protective plate 3 and the receiving groove 4 from being released.

[0029] On both sides of the frame 1, two sliding grooves 10 are provided. Inside each sliding groove 10, a slider 11 is slidably connected. On the outside of each rotating shaft 2, a connecting groove 12 is provided. The slider 11 is slidably connected inside the connecting groove 12, which is convenient for restricting the rotation of the rotating shaft 2. On both sides of the frame 1, two mounting holes 13 are provided. The mounting holes 13 communicate with the sliding grooves 10. The mounting holes 13 are threaded holes. Inside each mounting hole 13, a fixing screw 14 is threadedly connected. The fixing screw 14 is in contact with the outside of the slider 11, which is convenient for fixing the slider 11. By setting the slider 11 and cooperating with the fixing screw 14, at this time, the slider 11 enters the inside of the connecting groove 12. Then rotate the fixing screw 14 so that the fixing screw 14 is in contact with the outside of the slider 11. At this time, the position of the slider 11 is fixed, and at this time, the rotating shaft 2 cannot rotate, preventing the protective plate 3 and the connecting plate 5 from rotating during use and causing the protective mechanism to lose its protective effect.

[0030] On one side of each connecting plate 5 away from the protective plate 3, a pull rod 15 is provided. The pull rod 15 is composed of a concave body and two cuboids, which is convenient for pulling the connecting plate 5. Two through holes 16 are provided on the outside of the connecting plate 5.

[0031] Working principle:

[0032] First step, when using the rolling mill, after the connecting shaft is connected to the power equipment, at this time, rotate the protective plate 3 so that the protective plate 3 covers the connection between the connecting shaft and the power equipment. If the length of the protective plate 3 is not enough, at this time, rotate the limit screw 7 so that the limit screw 7 is no longer in contact with the connecting plate 5. Then pull the connecting plate 5 so that the length formed by the protective plate 3 and the connecting plate 5 meets the working requirements. After adjustment, rotate the limit screw 7 so that the limit screw 7 is in contact with the connecting plate 5. At this time, the connecting plate 5 is fixed. At this time, the protective plate 3 and the connecting plate 5 cover the connection position, preventing the staff from approaching the connection, and at the same time, it is convenient to adjust the length formed by the protective plate 3 and the connecting plate 5 and the position of the protective plate 3 according to the actual situation;

[0033] Second step, at this time, insert the slider 11 into the inside of the connecting groove 12. Then rotate the fixing screw 14 so that the fixing screw 14 is in contact with the outside of the slider 11. At this time, the position of the slider 11 is fixed, and at this time, the rotating shaft 2 cannot rotate, preventing the protective plate 3 and the connecting plate 5 from rotating during use and causing the protective mechanism to lose its protective effect.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
