[0002] Industrial guardrails refer to protective facilities used in the industrial field to ensure personnel safety, isolate dangerous areas, and protect equipment safety. Corrugated guardrails are a type of protective plate made of high-quality steel plates through a specific process. This type of plate is usually processed into a continuous corrugated shape to increase its rigidity and reduce its weight.

[0003] When the length of the corrugated guard plate is not enough during use, it needs to be extended by welding.

[0039] In the embodiment, the pushing mechanism 10 comprises two groups of first fixed blocks 101 which are symmetrical to each other, the lower end of the first fixed block 101 is fixedly connected with the bottom plate 1, the opposite side of the two groups of first fixed blocks 101 is rotatably connected with the first rotating block 102 through the rotating shaft, the upper end of the first rotating block 102 is fixedly connected with the single-stage cylinder 103, the output end of the single-stage cylinder 103 is fixedly connected with the second rotating block 104, the rear end of the second rotating block 104 is rotatably connected with the third rotating block 105 through the rotating shaft, and the upper end of the third rotating block 105 is fixedly connected with the first connecting rod 106.

[0040] Specifically, the single-stage cylinder 103 is started, the output end of the single-stage cylinder 103 pushes the second rotating block 104 to move upward, then under the connection of the third rotating block 105, the first connecting rod 106 is pushed to move, at the same time under the connection of the second fixed block 107, the first connecting rod 106 lifts the supporting plate one 4 and rotates the first connecting rod 106 to the inside of the first fixed cylinder 108 through the first rotating column 109, so as to limit one end of the first connecting rod 106, and make the first connecting rod 106 rotate and overturn with the supporting plate one 4 as the center of the first fixed cylinder 108 under the pushing force of the single-stage cylinder 103.

[0041] In the embodiment, the front end of the first connecting rod 106 is rotatably connected with the second fixed block 107 through the rotating shaft, one side of the second fixed block 107 is fixedly connected with the supporting plate one 4, the front end of the first connecting rod 106 is fixedly connected with the first rotating column 109, the outer side of the first rotating column 109 is rotatably connected with the first fixed cylinder 108, the front end of the first fixed cylinder 108 is fixedly connected with the fixed plate 9, the upper end of the first connecting rod 106 is fixedly connected with the fourth rotating block 110, the front end of the fourth rotating block 110 is rotatably connected with the second connecting rod 111 through the rotating shaft, and the rear end of the second connecting rod 111 is rotatably connected with the fifth rotating block 112 through the rotating shaft.

[0042] Specifically, in the process of overturning of the first connecting rod 106 and the supporting plate one 4, the third connecting rod 113 is connected with the first connecting rod 106 through the second connecting rod 111, and is rotatably connected with the outer side of the second rotating column 117 through the second fixed cylinder 118, and is rotatably connected with the second connecting rod 111 through the fourth connecting rod 116, so as to pull the second connecting rod 111 without hindering its rotation, so as to stably overturn the supporting plate one 4 under the pushing of the single-stage cylinder 103.

[0043] In this embodiment, the upper end of the fifth rotating block 112 is fixedly connected to the third connecting rod 113, the front end of the third connecting rod 113 is rotatably connected to the third fixed block 114 through a rotating shaft, one side of the third fixed block 114 is fixedly connected to the support plate 4, the upper end of the second connecting rod 111 is fixedly connected to the sixth rotating block 115, the front end of the sixth rotating block 115 is rotatably connected to the fourth connecting rod 116 through a rotating shaft, the front end of the fourth connecting rod 116 is fixedly connected to the second rotating column 117, the outer side of the second rotating column 117 is rotatably connected to the second fixed cylinder 118, and the front end of the second fixed cylinder 118 is fixedly connected to the fixed plate 9.

[0044] Specifically, the support plate 4 is driven by the pushing mechanism 10 to move and flip, so as to facilitate the loading and unloading of the corrugated plates that need to be welded. When the support plate 4 is driven by the pushing mechanism 10 with the first corrugated plate 2 and the second corrugated plate 3 perpendicular to the bottom plate 1, the second corrugated plate 3 is in a vertical state and freely falls on the upper end of the first corrugated plate 2 by its own gravity. Under the support of the second corrugated plate 3's own gravity, the welding joint between the first corrugated plate 2 and the second corrugated plate 3 will be more stable and firm.

[0045] When in use, the base plate 1 is placed on the horizontal ground, and the support plate 4 is vertically located at the upper end of the base plate 1. Then the single-stage cylinder 103 is started, and the output end of the single-stage cylinder 103 pushes the second rotating block 104 to move upward. Then, under the connection of the third rotating block 105, the first connecting rod 106 is pushed to move. At the same time, under the connection of the second fixed block 107, the first connecting rod 106 is lifted with the support plate 4, and is rotated and connected to the inner side of the first fixed cylinder 108 through the first rotating column 109. One end of the first connecting rod 106 is restricted, so that the first connecting rod 106 is rotated and flipped with the support plate 4 around the first fixed cylinder 108 as the center under the thrust of the single-stage cylinder 103. The process of flipping the first connecting rod 106 and the support plate 4 In the embodiment, the third connecting rod 113 is connected to the first connecting rod 106 through the second connecting rod 111, and is rotatably connected to the outer side of the second rotating column 117 through the second fixed cylinder 118. At the same time, the fourth connecting rod 116 is rotatably connected to the second connecting rod 111, which can pull the second connecting rod 111 without hindering its rotation. In this way, the support plate 4 can be stably flipped under the push of the single-stage cylinder 103, so that the support plate 4 is flipped from a vertical state to an inclined state, and then the first corrugated plate 2 and the second corrugated plate 3 that need to be welded and extended can be placed on the support plate 4. At this time, the frosted plate 85 is first located on the side away from the support plate 4. Specifically, the staff will first place the first corrugated plate 2 on the support plate 4 and between the two sets of arc plates 78. , and then, through the tilted state of the support plate 4 and under the restriction of the two sets of arc plates 78, the first corrugated plate 2 passes through the corrugated baffle 2 79 and the corrugated baffle 1 74 and slides to between the corrugated baffle 3 6 and the support plate 4, and then the second motor 82 is started to rotate the drum 83, so that the positions of the welding gun 813 and the frosting plate 85 are changed, and the frosting plate 85 is rotated to the top of the first corrugated plate 2, and then the second corrugated plate 3 is placed on the support plate 4. At this time, the second corrugated plate 3 will slide to the position between the corrugated baffle 2 79 and the support plate 4, and the lower end of the second corrugated plate 3 will rest on the frosting plate 85, and then the multi-stage cylinder 71 is started to shrink. During the shrinkage process of the multi-stage cylinder 71, the frosting plate 85 and At the same time, the second corrugated plate 3 moves downward until the lower end of the frosting plate 85 contacts the upper end of the first corrugated plate 2. At the same time, the corrugated baffle 1 74 will be attached to the surface of the first corrugated plate 2, and the corrugated baffle 2 79 will be attached to the surface of the second corrugated plate 3. Then the single-stage cylinder 103 is driven again to shrink the output end, so that the support plate 1 4 returns to its original vertical state, and the first corrugated plate 2 and the second corrugated plate 3 are flipped from tilt to a state perpendicular to the bottom plate 1. Then the first motor 713 can be started to rotate the threaded rod 710. Through the screw principle, the moving block 81 is moved backward and parallel, and the frosting plate 85 is driven to move between the first corrugated plate 2 and the second corrugated plate 3. After the frosting plate 85 is moved out from between the first corrugated plate 2 and the second corrugated plate 3,When the second corrugated plate 3 loses the support of the frosting plate 85, it will fall to the upper end of the first corrugated plate 2 by its own gravity, so that the welding point of the first corrugated plate 2 and the second corrugated plate 3 are connected. At this time, the second motor 82 is started again, so that the rotating drum 83 drives the frosting plate 85 and the welding gun 813 to change positions again, so that the welding gun 813 rotates to the position where the first corrugated plate 2 and the second corrugated plate 3 are ready for welding. At the same time, the moving rod 89 will contact the surface of the second corrugated plate 3 under the action of the spring 811, and then the first motor 713 is reversed. The welding gun 813 starts welding at the same time, so that the moving block 81 moves the welding gun 813 and the moving rod 89 forward smoothly, and the welding gun 813 then contacts the first corrugated plate 2 and the second corrugated plate 3. The first corrugated plate 2 and the second corrugated plate 3 are welded together. During the movement, the movable rod 89, connected by the spring 811, slides inside the first connecting groove 87 following the ups and downs of the corrugated plate. The welding gun 813 is connected by the third connecting block 810 to simultaneously follow the ups and downs of the corrugated plate to weld. After the welding is completed, it is only necessary to restart the single-stage cylinder 103 so that the output end of the single-stage cylinder 103 pushes the second rotating block 104 to move. Then, the above operation is repeated to make the support plate 4 with the welded first corrugated plate 2 and the second corrugated plate 3 flip from a vertical state to a horizontal state. The welded first corrugated plate 2 and the second corrugated plate 3 can then be removed by the staff.
