[0023] As Figure 1 , 2 , 3: a guard mechanism based on a plate shearing machine, comprising a plate shearing machine body 101, the feeding port of the plate shearing machine body 101 is provided with a fixed assembly at both ends, two sets of fixed assemblies are used for supporting a plurality of guard plates 102 and a plurality of anti-collision plates, two sets of fixed assemblies are provided so that each part between the two sets of fixed assemblies can be fixed, a plurality of guard plates 102 are arranged between the two sets of fixed assemblies, a plurality of guard plates 102 are arranged so as to prevent the hands or other body parts of the operator from accidentally entering the shearing area, thereby protecting the operator, and the plurality of guard plates 102 are evenly arranged along the horizontal direction, thereby further improving the protection effect.

[0024] Each guard plate 102 is arranged as a vertical Z-shaped structure, which can not only effectively block foreign matter from entering the shearing area, but also can avoid foreign matter flying out during shearing, and can be blocked by the Z-shaped structure, one anti-collision block 103 is arranged between every two guard plates 102, the anti-collision block 103 is arranged so as to avoid the thick plate lifted by the crane from colliding with the plate shearing machine body 101 when placed, thereby avoiding damage to the plate shearing machine body 101, further improving the protection effect of the plate shearing machine body 101, the anti-collision block 103 is connected between every two guard plates 102, thereby protecting the plate shearing machine body 101 when the thick plate is lifted and placed on the plate shearing machine body 101, the cross section of each anti-collision block 103 is arranged as a trapezoidal structure, the trapezoidal inclined surface of the anti-collision block 103 is arranged downward and away from the discharge port of the plate shearing machine body 101, thereby effectively absorbing and dispersing the impact force received.

[0025] As Figure 3 , 4As shown: Each anti-collision block 103 and protective plate 102 is provided with mounting plates 104 on both sides. The mounting plates 104 allow the anti-collision block 103 and protective plate 102 to be connected, so that it is easy to disassemble and install when damage occurs during protection and replacement or maintenance is required. Partial replacement can be performed after disassembly and installation, thus effectively saving costs. Each anti-collision block 103 and each protective plate 102 are fixedly connected to the mounting plates 104 on both sides, so that the connection structure is more stable. Every two adjacent mounting plates 104 are connected by bolts and nuts, so that the anti-collision block 103 and protective plate 102 are easy to disassemble and install when replacement or maintenance is required.

[0026] like Figure 1 , 3 As shown: Each nut is provided with a locking washer between itself and the mounting plate 104 it contacts, which can prevent the bolts and nuts from loosening due to vibration of the shearing machine body 101 during operation, thereby further improving the stability of the protection. The locking washer is fitted on the bolt, making the connection structure more stable.

[0027] like Figure 2 , 4 As shown: Each set of fixing components includes a mounting column 105 set on the feed port side of the shearing machine body 101. The mounting column 105 is set so that the components on it can be stably supported on the shearing machine body 101. The mounting column 105 is bolted to the feed port of the shearing machine body 101, so that the mounting column 105 and the components on it can be stably supported. A fixing plate 106 is set on the vertical surface of the mounting column 105 away from the discharge port of the shearing machine body 101. The fixing plate 106 can not only support the components on it, but also adjust the position of multiple protective plates 102 and anti-collision blocks 103 through multiple adjustment slots 107. The fixing plate 106 is fixedly connected to the mounting column 105, so that the connection structure is more stable. Two protective plates 102 located at the edge are respectively connected to the fixing plate 106, so that multiple protective plates 102 and multiple anti-collision blocks 103 can be stably supported.

The mounting blocks 108 allow the protective plates 102 at the edges to be adjusted in position within multiple adjustment slots 107, thus allowing for adjustment according to the desired viewing angle. The mounting blocks 108 are fixedly connected to the two protective plates 102 at the edges, making the connection structure more stable. Multiple adjustment slots 107 are also provided on the vertical surfaces of the two fixed plates 106 facing the protective plates 102. The multiple adjustment slots 107 allow the protective plates 102 at the edges to be adjusted in position within multiple adjustment slots 107, thus allowing for adjustment according to the desired viewing angle. The two protective plates 102 at the edge can be adjusted within the multiple adjustment slots 107 opened on the two fixed plates 106, thereby facilitating the adjustment of their position according to the required viewing angle. The multiple adjustment slots 107 can be integrally formed with the fixed plates 106 by casting in a mold during manufacturing, thereby making their connection structure more stable. The two mounting blocks 108 are snapped into the corresponding adjustment slots 107, thereby providing support and facilitating disassembly and assembly. The two mounting blocks 108 can be adjusted in position within the multiple adjustment slots 107 as needed, thereby facilitating the change of position to optimize the viewing angle.

[0029] like Figure 2 , 3 As shown: Each protective plate 102 is provided with several observation slots 109. The presence of several observation slots 109 can further improve the observation effect, and the situation can be observed when the thick plate is being cut, so as to further avoid accidents. The observation slots 109 can be cast with each protective plate 102 through a mold during the manufacturing process, so that the connection structure is more stable.
