[0006] Preferably, the support assembly includes a plurality of support rods connected to the periphery of the support plate, and the plurality of support rods are equidistantly distributed along the periphery of the support plate. Each support rod is slidably connected to a slide rod, and the end of each slide rod away from the support plate passes through the inner wall of the support rod and is connected to an abutment plate.

[0007] Preferably, the support assembly further includes a lead screw rotatably connected to the bottom of the support plate, a lead block is threadedly connected to the outer side of the lead screw, and traction rods are rotatably connected to all four sides of the lead block.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This utility model provides a municipal manhole cover anti-fall device, which includes: a support plate 1; a groove 11 is provided on the top of the support plate 1, and a rotating part 12 is rotatably connected in the groove 11; wherein, a support component is provided around the support plate 1, and the support plate 1 can be installed in the manhole through the support component; a buffer component is provided on the top of the support plate 1, and the buffer component can reduce the impact of falling objects.

[0021] It should be noted that: Support plate 1 is the basic load-bearing component of the entire fall arrestor. Groove 11 is located at the top center of support plate 1. The groove is circular in shape and of moderate depth to ensure that the rotating part 12 can be stably installed within it. Support components are evenly distributed around support plate 1, providing stable support. Their core function is to securely install support plate 1 within the wellhead, preventing displacement or shaking during use. Buffer components are installed on top of support plate 1, primarily used to reduce the impact of falling objects.

[0022] In an embodiment of this utility model, the support assembly includes a plurality of support rods 2 connected to the periphery of the support plate 1, and the plurality of support rods 2 are equidistantly distributed along the periphery of the support plate 1. Each support rod 2 is slidably connected to a slide rod 21. The end of each slide rod 21 away from the support plate 1 passes through the inner wall of the support rod 2 and is connected to an abutment plate 22. The support assembly also includes a lead screw 23 rotatably connected to the bottom of the support plate 1. A lead block 24 is threadedly connected to the outer side of the lead screw 23. A traction rod 25 is rotatably connected to the periphery of the lead block 24. The end of the traction rod 25 away from the lead block 24 is connected to the bottom of the slide rod 21 through a connecting block. A groove for the connecting block to slide is provided at the bottom of the support rod 2. The bottom of the rotating part 12 passes through the support plate 1 through a connecting shaft and is connected to the top of the lead screw 23. A limit block is connected to the bottom of the lead screw 23.

[0023] It should be noted that multiple support rods 2 are equidistantly distributed along the periphery of the support plate 1, connecting to the four sides of the support plate 1 to form a stable support frame. This equidistant distribution ensures that the supporting force is evenly applied to the support plate 1, effectively avoiding equipment tilting or instability caused by uneven support. The sliding rod 21 slidably connected within each support rod 2, and the abutment plate 22 connected to one end of the sliding rod 21, enable a tight fit between the equipment and the wellhead. When the equipment needs to be installed, the abutment plate 22 can directly contact the inner wall of the wellhead. By adjusting the sliding position of the sliding rod 21 within the support rod 2, it can adapt to wellheads of different sizes, ensuring that the equipment can be stably installed within the wellhead. The lead screw 23 in the support assembly is rotatably connected to the bottom of the support plate 1, and the threaded block 24 on its outer side is the core transmission component of the entire support adjustment system. When the lead screw 23 rotates, the threaded block 24 moves along the axial direction of the lead screw 23. The traction rod 25, which rotates around the wire block 24, and the connection between the traction rod 25 and the bottom of the slide rod 21 via the connecting block, form an efficient transmission link. When the wire block 24 moves up and down, the traction rod 25 drives the slide rod 21 to slide within the support rod 2, thereby adjusting the contact position between the abutment plate 22 and the inner wall of the wellhead. The sliding groove at the bottom of the support rod 2 provides guidance for the movement of the connecting block, ensuring the stability of the slide rod 21 during sliding and avoiding equipment jamming or instability caused by deviation of the connecting block's movement trajectory. The bottom of the rotating part 12 passes through the support plate 1 via a connecting shaft and connects to the top of the wire rod 23. When the rotating part 12 rotates within the groove 11, it drives the wire rod 23 to rotate synchronously. The rotation of the wire rod 23, in turn, causes the wire block 24 to move, thereby adjusting the position of the slide rod 21 and the abutment plate 22 via the traction rod 25.

[0024] In an embodiment of this utility model, the buffer assembly includes a guide rod 3 installed on the top of each support rod 2, and a guide block 31 is slidably connected to the outer side of each guide rod 3. A buffer rod 32 is connected to the top of each guide block 31, and a buffer plate 33 is connected to the top of each buffer rod 32. A through hole is opened on one side of the center of the buffer plate 33. A buffer spring 34 is sleeved on the outer side of each guide rod 3, and the buffer spring 34 is located on the side of the guide block 31 close to the support plate 1.

[0025] It should be noted that: the guide rod 3 is installed on top of each support rod 2, providing a stable guiding path for the entire buffer system. The guide block 31, which is slidably connected to the outside of the guide rod 3, can slide smoothly along the axial direction of the guide rod 3. The buffer rod 32 connected to the top of each guide block 31 together supports the buffer plate 33 above. As the component that directly receives falling objects, the buffer plate 33 has a through hole on one side of its center, allowing the user to drive the rotating part 12 through the through hole. The buffer spring 34 is sleeved on the outside of each guide rod 3 and is located on the side of the guide block 31 closer to the support plate 1. When an object falls and impacts the buffer plate 33, the buffer plate 33 will drive the guide block 31 to slide downward along the guide rod 3, compressing the buffer spring 34. The buffer spring 34, with its own elastic properties, converts the impact force generated by the falling object into elastic potential energy and stores it, thereby slowing down the falling speed of the object and reducing the damage of the impact force to the equipment and the facilities below. After the impact force disappears, the buffer spring 34 will gradually return to its original shape, pushing the buffer plate 33 to reset, preparing for the next possible falling object.

[0026] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
