Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective devices, in particular to a safety protective device used in a steel rolling mill area. Background Art
[0002] At steel rolling mills, equipment failures and other unexpected circumstances can cause interruptions in the rolling process during high-speed operation. Broken steel can then randomly escape from the mill, potentially injuring workers. Alternatively, workers can enter the mill area without permission, potentially causing personal injury. Therefore, to ensure personnel safety, safety nets are often installed near the mill to prevent or mitigate accidents.
[0003] Existing safety nets generally consist of columns, a protection frame, and a safety net. Connecting ears are fixedly connected to the side walls of the columns and the protection frame. Bolting the connecting ears together secures the safety net. While this installation method is simple, it also has the problem of being inflexible. Specifically, due to the fixed connection between the connecting ears and the columns, the safety net can only be installed and used in a straight line. This is unsatisfactory when the safety net needs to be angled to enclose the rolling mill area, making it inconvenient to use.
[0004] Therefore, there is an urgent need to redesign a new safety protection device for the steel rolling mill area to solve the above problems. Utility Model Content

[0031] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0032] See also Figures 1 to 7 The utility model discloses a safety protection device for a steel rolling mill area, comprising a plurality of interconnected protection net mechanisms 1 and support mechanisms 2.
[0033] The protective net mechanism 1 includes a protective plate 101, to which a protective frame 102 is fixedly connected, and a protective net 103 is connected to the protective frame 102. The protective net mechanism 1 and the protective net 103 form a protective structure. If rolling is interrupted in the rolling mill, the broken workpiece will strike the protective net 103 or the lower protective plate 101 instead of flying out directly, thus reducing the risk of injury to on-site workers.
[0034] Preferably, the protective plate 101 and the protective net 103 are both made of steel to ensure the strength of the protective plate 101 and the protective net 103, so that the protective net mechanism 1 can better protect the broken rolled piece and make it difficult for the broken rolled piece to fly out. The thickness of the protective plate 101 is 30 mm.
[0035] In addition, the protective net 103 is woven from a number of ￠12mm steel bars, and the mesh holes formed by the steel bars are 30*30mm, which ensures the safety protection effect of the protective net 103 on the broken rolled pieces and prevents the pieces from flying out.
[0036] Specifically, the protection frame 102 is connected to the protection plate 101 by welding, and the first connection ear 104 is connected to the protection frame 102 by welding, so as to ensure the connection strength of the protection plate 101, the protection frame 102 and the first connection ear 104.
[0037] In addition, a pair of side walls of the protective plate 101 and the protective frame 102 are connected with a first connecting ear 104, and the protective net mechanism 1 can be connected to the support mechanism 2 through the first connecting ear 104, so that the protective net mechanism 1 can be installed and used.
[0038] Furthermore, a warning strip 105 is attached to the surface of the protective net mechanism 1, and the warning strip 105 can serve as a warning.
[0039] See also Figures 1 to 7 The support mechanism 2 is used to install the protective net mechanism 1 so that the protective net mechanism 1 can be used to safely protect the broken rolled piece and ensure the safety of on-site workers.
[0040] The support mechanism 2 includes a base plate 201, which is connected to the ground via expansion screws to ensure the secure installation of the support mechanism 2. A column 202 is fixedly connected to the base plate 201, and the column 202 is used to connect the protective net mechanism 1.
[0041] A pair of connecting parts are provided on the column 202, and a rotatable connecting mechanism is installed in the connecting part, and the rotatable connecting mechanism is connected to the first connecting ear 104. By setting the rotatable connecting mechanism, a certain angle can be formed between the adjacent pair of protective net mechanisms 1, such as Figure 1 The state shown can increase the flexibility of the use of the protective net mechanism 1, so that the protective net mechanism 1 can better adapt to the rolling mill site area environment and facilitate the use of the protective net mechanism 1.
[0042] See also Figures 1 to 7 The rotatable connecting mechanism includes a fixing rod 203, which is fixedly connected to the connecting portion and is used to install the second connecting ear 205 and the fixing sleeve 204.
[0043] A pair of fixing sleeves 204 are fixedly connected to the fixing rod 203, and a second connecting ear 205 is fixedly connected between the pair of fixing sleeves 204. The second connecting ear 205 can be connected to the first connecting ear 104, thereby fixing the protective net mechanism 1 to the support mechanism 2. That is, the protective net mechanism 1 connected to the second connecting ear 205 cannot rotate.
[0044] In addition, a movable sleeve 206 is rotatably connected to the outer side of the fixed rod 203. The movable sleeve 206 is arranged between a pair of fixed sleeves 204. A third connecting ear 207 is fixedly connected to the movable sleeve 206. Through the mutual cooperation between the first connecting ear 104 and the third connecting ear 207, the support mechanism 2 can be connected to another protective net mechanism 1. At the same time, because the movable sleeve 206 can rotate around the fixed rod 203, the protective net mechanism 1 connected to the third connecting ear 207 can form a certain installation angle with the adjacent protective net mechanism 1, that is, Figure 1 The state shown can increase the flexibility of the use of the protective net mechanism 1, so that the protective net mechanism 1 can better adapt to the rolling mill site area environment and facilitate the use of the protective net mechanism 1.
[0045] Preferably, the first connecting lug 104 is connected to the second connecting lug 205 and the third connecting lug 207 respectively by bolts.
[0046] Specifically, a locking bolt 208 is threadedly connected to the movable sleeve 206, and the locking bolt 208 contacts the fixing rod 203. The locking bolt 208 is used to lock the rotation angle of the third connecting ear 207 to fix the protective net mechanism 1 and ensure the stability of the installation of the protective net mechanism 1.
[0047] See also Figures 1 to 7 A pair of limiting columns 209 are connected to the top wall of the connecting portion. The pair of limiting columns 209 are symmetrical about the fixing rod 203. Figure 5 The limiting post 209 is used to limit the rotation distance of the third connecting ear 207 , that is, the third connecting ear 207 can only rotate within a range of 180 degrees, so that the third connecting ear 207 is not likely to collide with the second connecting ear 205 .
[0048] The third connecting lug 207 is connected to an indicator pin 210, and a graduated groove 211 is provided on the bottom wall of the connecting portion, with the indicator pin 210 corresponding to the graduated groove 211. The interaction between the indicator pin 210 and the graduated groove 211 facilitates the operator to determine the rotation angle of the third connecting lug 207, so that the pair of third connecting lugs 207 can be rotated to the same angle, thereby improving the connection efficiency between the first connecting lug 104 and the third connecting lug 207, and also ensuring the connection between the protective net mechanism 1 and the support mechanism 2.
[0049] Preferably, when the third connecting ear 207 is parallel to the second connecting ear 205 , the third connecting ear 207 is in a 0° state.
[0050] In addition, a limiting ring 212 is fixedly connected to the outer side of the fixed rod 203, and a snap-fitting groove matching the limiting ring 212 is provided in the movable sleeve 206. By snapping the limiting ring 212 into the snap-fitting groove, the movable sleeve 206 can be firmly fixed to the fixed rod 203, thereby ensuring the secure installation of the protective net mechanism 1.
[0051] During specific use, when installing the protective net mechanism 1 in the rolling mill area, first use the expansion screws to fix the support mechanism 2 to the ground, and then flexibly install the protective net mechanism 1 according to the on-site environment: directly connect one of the protective net mechanisms 1 to a pair of second connecting ears 205 with bolts. If another protective net mechanism 1 needs to be installed in a straight line with the adjacent protective net mechanism 1, loosen the locking bolt 208, rotate the third connecting ear 207, and make the third connecting ear 207 parallel to the second connecting ear 205, that is, the third connecting ear 207 is in the 0° state on the scale groove 211. Tighten the locking bolt 208, and use the bolts to install the other protective net mechanism 1 on a pair of third connecting ears 207, that is Figure 3 The status shown.
[0052] If another protective net mechanism 1 needs to be installed tilted with the adjacent protective net mechanism 1, it is necessary to loosen the locking bolt 208 and rotate the pair of third connecting ears 207. The third connecting ears 207 can be rotated to the same angle by the cooperation of the indicator needle 210 and the scale groove 211. After the third connecting ears 207 are rotated, they are locked and fixed with the locking bolt 208, and then the other protective net mechanism 1 is installed on the third connecting ears 207 with the bolts. Figure 1 The status shown.
[0053] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
