Description

Technical Field

[0001] This utility model relates to the field of hot-rolled strip production technology, and in particular to a safety protection device for hot-rolled strip production. Background Technology

[0002] Hot-rolled plate and strip is a general term for hot-rolled steel plates and strips, commonly known as hot plates. It is also often written as "stripping" or "hot-rolled plate," but they all refer to the same type of hot-rolled plate, which is a steel plate with a width of 600mm or more and a thickness of 0.35-200mm, and a steel strip with a thickness of 1.2-25mm. During the production of hot-rolled plate and strip, in order to ensure production safety, safety protection devices are usually used to shield and protect them to prevent workers from getting too close and posing safety hazards.

[0003] Traditional installation and protection methods mostly involve directly using guardrails for safety shielding. However, guardrails take up a large area during use and are inconvenient to store after production, which affects the later transportation of products by workers. Therefore, they have the drawback of being inconvenient for safety protection and cannot meet the needs of customers. Utility Model Content

A support plate 19 is fixedly connected to the bottom of the right side of the concave plate 6. The connection between the support plate 19 and the protective plate 9 is tightly fitted. There are four mounting holes at the four corners of the top of the bottom plate 1.

[0024] This utility model, by setting up a base plate 1, a drive box 2, a screw 3, a rectangular plate 4, a toothed plate 5, a concave plate 6, a rotating shaft 7, a gear 8, a protective plate 9, a servo motor 12, a main helical gear 13, and a driven helical gear 14, can conveniently provide safety protection and obstruction for hot-rolled strip production sites. At the same time, it is convenient to rotate and store the strip. By setting up an extension frame 10 and a limiting component 11, the protective length of the protective plate 9 can be adjusted. With the above structure, it can be conveniently used for safety protection of production sites, thereby meeting the needs of customers.

[0025] Example 2

[0026] Reference Figure 1 , Figure 2 and Figure 4 The limiting component 11 includes a limiting bolt 111. The outer surface of the limiting bolt 111 is threadedly connected to the connection of the extended frame 10. The top and bottom of the protective plate 9 are evenly provided with pin holes 112 that cooperate with the limiting bolt 111. One end of the limiting bolt 111 extends into the inner cavity of the pin hole 112. There are twenty-four pin holes 112, which are equidistantly distributed on the upper and lower sides of the protective plate 9.

[0027] This utility model can limit the connection between the extended frame 10 and the protective plate 9 by setting the limiting bolt 111 and the pin hole 112.

[0028] The implementation principle of this utility model is as follows: When in use, the operator uses the mounting holes and screws to fix the device in the designated safe production area. Then, the device is electrically connected to the mains power. When it is necessary to provide safety protection for the production area, the operator starts the external controller of the servo motor 12, which drives the main helical gear 13 to rotate. The main helical gear 13 drives the driven helical gear 14 to rotate. The driven helical gear 14 drives the screw 3 to rotate on the inner surface of the rectangular plate 4, causing the rectangular plate 4 to move the toothed plate 5 upward. At the same time as the toothed plate 5 moves upward, the toothed plate 5 drives the gear 8 to rotate counterclockwise around the rotating shaft 7. This causes the gear 8 to drive the protective plate 9 and the extended frame 10 to rotate counterclockwise to a horizontal state. At the same time, the bottom of the protective plate 9 is tightly fitted to the connection of the support plate 19, thereby achieving safety protection for the production area.

[0029] When it is necessary to expand the safety protection shielding range of the production area, the workers rotate and move the limiting bolts 111 on both sides in sequence, so that the limiting bolts 111 rotate and move out of the inner cavity of the pin hole 112. Then, the workers pull the extension frame 10 laterally, so that the extension frame 10 slides on the outer surface of the protective plate 9. When the extension frame 10 moves laterally to the appropriate shielding length, the extension frame 10 drives the limiting bolts 111 on both sides to move to the position of the corresponding pin hole 112. Then, the workers rotate the limiting bolts 111 on both sides in reverse, so that the limiting bolts 111 rotate and move into the inner cavity of the pin hole 112, thereby limiting the connection between the extension frame 10 and the protective plate 9, and completing the expansion of the safety protection shielding range of the production area.

[0030] When production is completed and the product needs to be transferred and the protective shield removed, the staff can reverse the above operation to make the servo motor 12 rotate in the opposite direction. This causes the toothed plate 5 to drive the gear 8 to rotate clockwise around the shaft 7. The gear 8 then drives the protective plate 9 and the extension frame 10 to rotate clockwise and become perpendicular, thus achieving the rotation and storage of the protective plate 9 and avoiding interference with the transfer of the product. This device is simple to operate and easy to use for safety protection and adjustment of the production site, thereby meeting the needs of customers.

[0031] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
