Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering facilities technology, specifically relating to a noise-reducing and vibration-damping road manhole cover with an adjustable component. Background Technology

[0002] Manhole covers, as essential coverings for urban underground infrastructure, were initially made of cast iron to meet strength and durability requirements. Their development has evolved from simple cast iron covers to composite materials, and in the late 20th century, they were gradually standardized, incorporating anti-slip, anti-theft, and noise-reducing features. In recent years, they have further developed towards intelligent designs. Their core applications cover maintenance access for underground pipelines such as municipal drainage, power and communication lines, and gas and heating systems. Ensuring public safety while maintaining aesthetics in roads, squares, and residential areas, they have become an indispensable part of modern urban infrastructure.

[0003] Traditional cast iron manhole covers are prone to metal fatigue and breakage under repeated vehicle pressure, and the impact noise generated by rigid contact seriously affects the lives of nearby residents. Most manhole covers have simple locking mechanisms that are prone to loosening and displacement under frequent vibration, which not only produces abnormal noise but also poses safety hazards. Therefore, noise reduction and vibration damping road manhole covers with adjustment components have emerged. Utility Model Content

[0004] The purpose of this invention is to provide a noise-reducing and vibration-damping road manhole cover with an adjustment component, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0011] In a preferred embodiment of this utility model, the fixing layer is made of polyethylene material, the absorbent layer is made of foam material, the absorbent layer is made of rubber granules, and the connecting layer is made of silicone material.

[0012] As a preferred embodiment of this utility model, the movable component includes a connecting frame movably connected to the inner wall of the bottom shell, a cover plate fixedly connected to the surface of the connecting frame, and an anti-slip groove formed on the surface of the cover plate.

[0013] As a preferred embodiment of the present invention, the movable component further includes a connector hinged to the side wall of the connecting frame, a movable rod inserted into the side wall of the cover plate, and a locking block sleeved on the surface of the movable rod.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting up connecting components and moving components, it effectively solves the problems of traditional manhole covers such as easy loosening, high noise, and poor shock absorption performance. Among them, the combined use of polyethylene fixing layer, foam absorption layer, rubber particle dispersion layer and silicone connecting layer in the multi-layer buffer component reduces the vibration and noise when vehicles run over it.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides a noise-reducing and vibration-damping road manhole cover with an adjustment component, comprising:

[0026] The bottom shell 101, the connecting seat 102 fixedly connected to the side wall of the bottom shell 101, the fixing port 103 opened on the side wall of the connecting seat 102, the support plate 104 fixedly connected to the side wall of the connecting seat 102, the connecting component 105 disposed on the inner wall of the bottom shell 101, and the moving component 106 disposed on the surface of the connecting component 105.

[0027] The fixing port 103 facilitates the use of expansion bolts to fix the bottom shell 101 to the road surface, ensuring the stability of the bottom shell 101 when connected to the ground. The support plate 104 ensures the integrity of the bottom shell 101 when it is subjected to impact.

[0028] Specifically, the connecting component 105 includes a limiting seat 105a fixedly connected to the side wall of the bottom shell 101, and an insertion port 105b opened on the side wall of the limiting seat 105a. The connecting component 105 also includes a mounting plate 105c fixedly connected to the inner wall of the bottom shell 101, and a buffer component 105d disposed on the side wall of the mounting plate 105c. The buffer component 105d includes a fixing layer 105d-1 fixedly connected to the side wall of the mounting plate 105c, an absorbent layer 105d-2 fixedly connected to the surface of the fixing layer 105d-1, a dispersion layer 105d-3 laid on the surface of the absorbent layer 105d-2, and a connecting layer 105d-4 sleeved on the surface of the dispersion layer 105d-3.

[0029] Furthermore, the fixing layer 105d-1 is made of polyethylene material, the absorbing layer 105d-2 is made of foam material, the absorbing layer 105d-2 is made of rubber granules, and the connecting layer 105d-4 is made of silicone material.

[0030] Preferably, the movable component 106 includes a connecting frame 106a movably connected to the inner wall of the bottom shell 101, a cover plate 106b fixedly connected to the surface of the connecting frame 106a, and an anti-slip groove 106c formed on the surface of the cover plate 106b. The movable component 106 also includes a connector 106d hinged to the side wall of the connecting frame 106a, a movable rod 106e inserted into the side wall of the cover plate 106b, and a locking block 106f sleeved on the surface of the movable rod 106e.

[0031] It should be noted that the connector 106d is bolted to the socket 105b of the limit seat 105a, ensuring that the connecting frame 106a can drive the cover plate 106b to flip. One end of the movable rod 106e is rectangular and the other end is cylindrical. Moving the movable rod 106e can drive the locking block 106f to rotate. The locking block 106f is movably connected to the bottom of the bottom shell 101.

[0032] In use, the base shell 101 is fixed to the road surface using expansion screws and mounting holes. The connecting bracket 106a is moved to place the cover plate 106b over the base shell 101. The connector 106d ensures the flexibility of the cover plate 106b during movement. After the cover plate 106b is closed, the movable rod 106e is moved, causing the locking block 106f to rotate. This fixes the side wall of the locking block 106f to the bottom of the base shell 101, ensuring the stability of the cover plate 106b after closure. When a vehicle runs over a manhole cover, the outermost connecting layer 105d-4 of the buffer component 105d absorbs the pressure on the manhole cover and transmits the force to the surface of the dispersion layer 105d-3. The dispersion layer 105d-3, made of rubber granules, absorbs part of the force and transmits the force to the absorption layer 105d-2. The absorption layer 105d-2 is made of foam material to absorb the force. The fixing layer 105d-1 provides stable support when the buffer component 105d disperses and absorbs the force.

[0033] In summary, the connection component 105 and the moving component 106 achieve good stability and noise reduction / vibration damping effects. The rigid connection between the bottom shell 101 and the road surface and the support plate 104 structure enhances the overall impact resistance. The combined use of the polyethylene fixing layer 105d-1, foam absorption layer 105d-2, rubber particle dispersion layer 105d-3, and silicone connecting layer 105d-4 in the multi-layer composite buffer component 105d effectively decomposes and absorbs the dynamic load during vehicle rolling, reducing noise transmission. At the same time, the design of the hinged connecting frame 106a and the lockable movable rod 106e ensures the flexibility of opening and closing the cover plate 106b, and ensures the stability after closure through the locking block 106f mechanism. This avoids the loosening and abnormal noise problems common in traditional manhole covers, improves the durability and environmental friendliness of the manhole cover under frequent loads, and is especially suitable for application scenarios with high noise reduction requirements, such as urban main roads and residential areas.
