Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling object safety protection, in particular to a safety protection device for preventing falling objects at the edge of a gutter on a roof of a steel mill. Background Art

[0002] A gutter is the concave portion between the two sides of a building's roof. Roof drainage can be divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into a gutter, which is then discharged through a rainwater pipe. The ditch that collects rainwater is called a gutter.

[0003] Gutters play a vital role in a steel mill's roof drainage system. However, the operation of a steel mill inevitably generates various waste and debris. If not properly handled, these materials may fall from the roof, posing not only a pollution threat to the ground environment but also a potential safety risk to workers working under the gutter. To address this issue, it is often necessary to install a falling object safety device. However, when objects slide along the roof, they generate significant impact force. Conventional protection devices often lack structural designs that can effectively absorb this force. After experiencing multiple impacts, the device's lifespan may be significantly reduced or even damaged, making it unable to continue to provide the necessary safety protection.

[0029] like Figure 1-5 As shown, the buffer mechanism includes a sliding shaft 18 fixedly connected to the inside of the mounting cavity 21, and sliding sleeves 17 are slidingly provided at both ends of the sliding shaft 18. The sliding sleeve 17 is fixedly connected to the second mounting bracket 22 at one end facing the buffer plate 4, and the buffer plate 4 is fixedly connected to the first mounting bracket 14 at one end corresponding to each second fixing pin 23 close to the limit plate 5. A connecting rod 16 is arranged between the first mounting bracket 14 and the second mounting bracket 22, and a damping block 20 is fixedly connected to the middle of the sliding shaft 18. Springs 19 are provided at both ends of the damping block 20, and the movable end of the spring 19 is fixedly connected to the sliding sleeve 17 in its corresponding position. When the buffer plate 4 moves close to the limit plate 5, the angle of the connecting rod 16 will change, pushing the second fixing pin 23 to slide toward the damping block 20. When the damping block 20 slides, the impact force is buffered by the deformation of the spring 19, and the impact force is absorbed by the damping block 20, and the received tangential impact force is converted and transferred to the damping block 20 for absorption, thereby reducing the impact damage caused by falling objects to the device.

[0030] like Figure 1-5 As shown, a second fixing pin 23 is fixedly connected inside the second mounting frame 22, a first fixing pin 15 is fixedly connected inside the first mounting frame 14, and both ends of the connecting rod 16 are rotatably connected to the first fixing pin 15 and the second fixing pin 23 respectively, and the first fixing pin 15 and the second fixing pin 23 serve to limit the rotation of the connecting rod 16.

[0031] like Figure 1-5As shown, the supporting mechanism includes a mounting plate 7 fixedly connected to the outer end of the wall 2, the top of the mounting plate 7 is fixedly connected to a connecting plate 6, the bottom end of the limiting plate 5 is fixedly connected to the connecting plate 6, and the limiting plate is installed by fixing the top of the mounting plate 7 to the connecting plate 6.

[0032] like Figure 1-5 As shown, a rib plate 8 is fixedly connected obliquely between the mounting plate 7 and the connecting plate 6. The rib plate 8 can form a stable triangular structure between the mounting plate 7 and the connecting plate 6, thereby improving the stability of the structure.

[0033] like Figure 1-5 As shown, the connecting plate 6 is an L-shaped plate, and the vertical end thereof abuts against the outer wall of the limiting plate 5 , and the outer end of the limiting plate 6 is also abutted against each other, thereby improving the connection stability of the limiting plate 5 .

The guide posts 13 are arranged through the buffer plate 4 , and the guide posts 13 serve as limiting guides for the movement of the buffer plate 4 .

[0036] Working principle: When an object falls from the roof, the object hits the high mesh net 9 and drives the buffer plate 4 to move. When moving, the buffer plate 4 is guided by multiple guide columns 13 to move toward the limit plate 5. The guide columns 13 serve as a limit guide for the movement of the buffer plate 4. When the buffer plate 4 moves close to the limit plate 5, the connecting rod 16 will change its angle, pushing the second fixed pin 23 to slide toward the damping block 20. The damping block 20 buffers the impact force through the deformation of the spring 19 when sliding, and absorbs the impact force through the damping block 20, and converts the received tangential impact force into absorption by the damping block 20, thereby reducing the impact damage caused by the falling object to the device and improving the service life of the device. After the impact, the buffer plate 4 can also be reset by restoring the deformation through the spring 19. The high mesh net 9 is hung with multiple first hooks 10 and second hooks 12 through the rings 11 at both ends, which is convenient for users to remove and replace the high mesh net 9 when it is damaged.
