[0025] Specifically, initially, the shielding plate 220 and the shielding plate 1 210 are laid flat on the top of the fence 120, thereby shielding the top of the press body 100. When the top of the press body 100 is inspected, the escalator 300 is pulled down and stepped on, so that the escalator 300 moves down, and the escalator 300 drives the shielding plate 1 210 to deflect through the rocker arm 230, so that the other side of the shielding plate 1 210 deflects upward, and the shielding plate 1 210 drives the shielding plate 2 20 to deflect, so that the shielding plate 1 The plate 1 210 and the shielding plate 2 220 are in an inverted V shape, so that the two shielding plates 220 can be opened to both sides, making it convenient for personnel to enter the fence 120. When the inspection is completed and the escalator 300 is moved down, the escalator 300 is pushed upward, and the shielding plate 220 is reset under the action of gravity, so that the shielding plate 1 210 and the shielding plate 2 220 cover the top of the fence 120 again, thereby protecting the components at the top of the press body 100, facilitating the opening and closing of the ceiling assembly 200, and facilitating operation.

[0026] Embodiment 1

[0027] like Figures 1 to 6As shown, in this embodiment, the outer wall of the other end of the fence 120 is fixedly connected to a sliding rail 240, the other end of the other side wall of the shielding plate 220 is rotatably connected to a sliding wheel 221, the sliding wheel 221 is slidably connected to the inner wall of the sliding rail 240, and fixed rails 260 are fixedly connected to both sides of the outer wall of one end of the fence 120, a long groove 261 is opened on one side wall of the fixed rail 260, a long groove 1 231 is opened on one side wall of the rocker arm 230, a connecting rod 250 is arranged between the rocker arm 230 and the adjacent fixed rail 260, one end of the connecting rod 250 is fixedly connected to a shaft rod 252, the shaft rod 252 is slidably connected to the inner wall of the long groove 1 231, and the other end of the connecting rod 250 is fixedly sleeved with a shaft rod 25 1, one end of the shaft rod 1 251 is slidably connected to the inner wall of the long groove 261, the other end of the outer wall of the fence 120 is located above the fixed rail 260 and is rotatably connected to the guide wheel 1 270, one side wall of the guide wheel 1 270 is fixedly connected to the guide wheel 271, the inner side wall of the guide wheel 1 270 is fixedly connected to the pull rope 1 272, one end of the pull rope 1 272 is wound and fixed to the outer wall of the shaft rod 1 251 on the adjacent side, the outer wall of one end of the fence 120 is located on one side of the guide wheel 1 270 and is fixedly connected to the fixing rod 280, the outer wall of the fixing rod 280 is rotatably sleeved with the guide wheel 3 281, the inner side wall of the guide wheel 271 is fixedly connected to the pull rope 282, and the pull rope 282 is fixedly connected to the top of the escalator 300 after passing the guide wheel 3 281.

[0028] In a specific implementation, when the escalator 300 is pulled downward, the escalator 300 pulls the guide wheel 271 to rotate through the pull rope 282, and the guide wheel 271 drives the guide wheel 1 270 to rotate, so that the guide wheel 1 270 reels the pull rope 1 272, thereby pulling the shaft rod 1 251 through the pull rope 1 272, so that the other end of the connecting rod 250 slides along the long groove 261, and one end of the connecting rod 250 pulls the rocker arm 230 to deflect through the shaft rod 252, thereby driving the shielding plate 1 210 to deflect upward, and driving the two shielding plates 220 to open to both sides, wherein the outer diameter of the guide wheel 1 270 is greater than The outer diameter of the guide wheel 271 pushes the escalator 300 upward, and the baffle plate 220 slides back to its original position under the action of gravity. During the process of the baffle plate 210 returning to a horizontal state, the rocker arm 230 pulls the guide wheel 270 through the pull rope 272, and the guide wheel 270 pulls the escalator 300 upward through the pull rope 282. When the baffle plate 210 is in a horizontal state, the horizontal distance between the center of gravity of the baffle plate 210 and the rotating shaft on one side of the baffle plate 210 increases, so that the sum of the pulling forces of the two pull ropes 282 is greater than the gravity of the escalator 300, thereby lifting the escalator 300.

[0029] Embodiment 2

[0030] like Figures 1 to 6As shown, in the present embodiment, the width of the second shielding plate 220 is greater than the width of the first shielding plate 210, and both the first shielding plate 210 and the second shielding plate 220 are mesh-shaped, and sliding rods 310 are fixedly arranged on both sides of the top of the escalator 300, and the sliding rods 310 are slidably connected to the fixed grooves 130 on the adjacent side, and a cross frame 110 is arranged on the outer side of the two fixed grooves 130, and the cross frame 110 is fixedly connected to the side wall at the top of the press body 100, and the top of the outer wall of one fixed groove 130 is fixedly connected to a limiting module 140, and the limiting module 140 includes a fixing card 141, and the fixing card 141 is fixedly connected to the fixing groove 130 on the adjacent side, and the inner wall of the fixing card 141 is slidably sleeved with an insert rod 142, and a guardrail 400 is fixedly connected to the outer wall of one end of the escalator 300.

[0031] In specific implementation, when the shielding plate 1 210 is in a vertical state, the shielding plate 220 is in an inclined state, which is convenient for the shielding plate 220 to slide and reset under the action of gravity. Through the setting of the limit module 140, when the escalator 300 is pulled down, the top of the escalator 300 is blocked by the insertion rod 142 to prevent the escalator 300 from accidentally moving up and closing between the two shielding plates 220 after the personnel moves to the top of the press body 100. When the personnel move up and down on the escalator 300, the insertion rod 142 is pulled outward to prevent the insertion rod 142 from interfering with the escalator 300, so as to facilitate the subsequent upward movement of the escalator 300. The downward escalator 300 is supported and limited by the cross frame 110 to prevent the shielding plate 1 210 from excessive outward deflection.
