Description

Technical Field

[0001] This application relates to the field of manhole covers, and more particularly to a flexible manhole cover for municipal asphalt pavements. Background Technology

[0002] In municipal construction, manhole covers are an essential part, mainly used to cover the entrances of underground facilities, such as drainage systems and power systems.

[0003] Currently, manhole covers mainly include cast iron manhole covers, composite material manhole covers, and steel fiber reinforced concrete manhole covers. During the construction process, corresponding installation slots are cut into the asphalt pavement to hold the manhole cover.

[0004] When manhole covers are subjected to frequent vehicle traffic, the asphalt pavement has a poor ability to disperse the pressure on the manhole cover, which means that the elastic deformation capacity and fatigue resistance of the manhole cover are reduced. This increases the noise when vehicles pass over the manhole cover, thus reducing the service life of the manhole cover, and therefore needs to be improved. Utility Model Content

[0005] To address the aforementioned issues, this application provides a flexible manhole cover for municipal asphalt pavements.

[0006] This application provides a flexible manhole cover for municipal asphalt pavements, which adopts the following technical solution:

[0007] A flexible manhole cover for municipal asphalt pavement includes a base and a manhole cover body. The base is provided with a support plate, and the support plate is provided with a support pad. The manhole cover body is provided with a buffer plate on the side near the support, and the buffer plate abuts against the support pad. The support plate is provided with a dispersing component for dispersing the pressure on the manhole cover body, and the dispersing component abuts against the buffer plate.

[0008] By adopting the above technical solution, the support pad and buffer plate work together to absorb part of the impact force received by the manhole cover. The dispersion component further disperses the impact force received by the manhole cover, reducing the pressure on the manhole cover and improving its elastic deformation capacity and fatigue resistance, thereby extending the service life of the manhole cover.

[0009] Preferably, the dispersion assembly includes a dispersion plate and a plurality of dispersion rods. The dispersion plate abuts against a buffer plate, and each dispersion rod is disposed on the side of the dispersion plate away from the buffer plate. The end of each dispersion rod away from the dispersion plate is connected to a support plate.

[0010] By adopting the above technical solution, when the manhole cover body is impacted, the dispersion plate absorbs part of the impact force and transmits it to the support plate through the dispersion rod, making it less likely for the impact force to concentrate on the manhole cover body, reducing the possibility of damage to the manhole cover body, and thus extending the service life of the manhole cover body.

[0011] Preferably, the dispersing plate is provided with a plurality of connecting blocks, each connecting block corresponds to a dispersing rod, each dispersing rod is provided with a connecting groove, and the connecting block is disposed in the connecting groove at the corresponding position.

[0012] By adopting the above technical solution, the connecting block and the connecting groove cooperate to provide positioning for the dispersing rod, so that the worker can place the dispersing plate more stably on each dispersing rod.

[0013] Preferably, the buffer plate is embedded with wire mesh.

[0014] By adopting the above technical solution, the wire mesh improves the overall structural strength of the buffer plate, so that the buffer plate can more stably absorb the impact force on the manhole cover body.

[0015] Preferably, the buffer plate has a connecting ring on the side near the support pad, the support pad has a clearance groove on the side near the buffer plate, the connecting ring is disposed in the clearance groove, the bottom of the clearance groove has a snap-fit ​​groove, and the connecting ring has a snap-fit ​​ring on the side away from the buffer plate, the snap-fit ​​ring is disposed in the snap-fit ​​groove.

[0016] By adopting the above technical solution, the connecting ring is inserted into the clearance groove and the snap ring is inserted into the snap groove, which increases the contact area between the buffer plate and the support pad and improves the connection stability between the buffer plate and the support pad.

[0017] Preferably, the support pad has a fixing ring on the side near the support plate, and the support plate has a fixing groove, with the fixing ring threadedly connected to the inner wall of the fixing groove.

[0018] By adopting the above technical solution, when the support pad needs to be installed, the worker aligns the retaining ring with the retaining groove and rotates the support pad, causing the retaining ring to be threaded into the inner wall of the retaining groove. After the support pad comes into contact with the support plate, the installation of the support pad is completed.

[0019] Preferably, the manhole cover body is provided with several friction-enhancing protrusions.

[0020] By adopting the above technical solution, the friction-enhancing protrusions increase the friction of the manhole cover surface, reducing the possibility of vehicles or pedestrians slipping when passing over the manhole cover.

[0021] Preferably, the manhole cover body has several lifting holes.

[0022] By adopting the above technical solution, the lifting hole facilitates the movement of the manhole cover body.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up support pads, buffer plates and dispersion components, the support pads and buffer plates absorb part of the impact force on the manhole cover body, and the dispersion components further disperse part of the impact force on the manhole cover body, thereby improving the elastic deformation capacity and fatigue resistance of the manhole cover body and extending the service life of the manhole cover body.

[0025] 2. By setting several connecting blocks, the dispersing rods are provided with limiting and positioning functions. On the one hand, this makes it convenient for workers to connect the dispersing plate and each dispersing rod, and on the other hand, it makes it difficult for the dispersing plate and each dispersing rod to separate.

[0026] 3. By installing wire mesh, the overall structural strength of the buffer plate is improved, so that the buffer plate can more stably absorb the impact force on the manhole cover. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a flexible manhole cover for municipal asphalt pavements. (See also...) Figure 1 and Figure 2 A flexible manhole cover for municipal asphalt pavement includes a base 1 and a cover body 2. A support plate 11 is fixed on the base 1, and a support pad 3 is detachably connected to the support plate 11. A buffer plate 4 is provided on the side of the cover body 2 near the support, and the buffer plate 4 abuts against the support pad 3. A dispersion component 5 is provided on the support plate 11 to disperse the pressure on the cover body 2, and the dispersion component 5 abuts against the buffer plate 4. The buffer plate 4 and the support pad 3 absorb part of the impact force on the cover body 2, and the dispersion component 5 further disperses part of the impact force on the cover body 2, improving the elastic deformation capacity and fatigue resistance of the cover body 2, thereby extending the service life of the cover body 2.

[0032] Reference Figure 2The buffer plate 4 is embedded with a wire mesh 41, which provides support for the buffer plate 4 and improves the overall structural strength of the buffer plate 4 so that the buffer plate 4 can absorb the impact force on the manhole cover body 2 more stably.

[0033] Both the buffer plate 4 and the support pad 3 are made of rubber. The rubber is soft so that the buffer plate 4 and the support pad 3 can absorb the impact force on the manhole cover body 2.

[0034] Reference Figure 2 To facilitate the installation of the support pad 3, a retaining ring 31 is glued to the side of the support pad 3 near the support plate 11. The support plate 11 has a retaining groove 111, and the retaining ring 31 is threaded into the inner wall of the retaining groove 111. When the support pad 3 needs to be installed, the worker aligns the retaining ring 31 with the retaining groove 111, and then rotates the support pad 3 so that the retaining ring 31 is threaded into the inner wall of the retaining groove 111, thus completing the installation of the support pad 3.

[0035] Reference Figure 2 In order to improve the fit between the support pad 3 and the buffer plate 4, a connecting ring 42 is provided on the side of the buffer plate 4 near the support pad 3, and a relief groove 32 is provided on the side of the support pad 3 near the buffer plate 4, and the connecting ring 42 is placed in the relief groove 32.

[0036] Furthermore, the bottom of the clearance groove 32 is provided with a snap-fit ​​groove 33, and the connecting ring 42 is provided with a snap-fit ​​ring 43 on the side away from the buffer plate 4. The snap-fit ​​ring 43 is disposed in the snap-fit ​​groove 33, and the cross-section of the snap-fit ​​ring 43 is circular. Both the connecting ring 42 and the snap-fit ​​ring 43 are made of rubber.

[0037] The cooperation between the connecting ring 42 and the relief groove 32, as well as the cooperation between the snap ring 43 and the snap groove 33, increases the contact area between the buffer plate 4 and the support pad 3. At the same time, the limiting effect of the snap ring 43 makes it difficult for the buffer plate 4 to separate from the support pad 3, which facilitates the subsequent absorption of the impact force on the manhole cover body 2 by the buffer plate 4 and the support pad 3.

[0038] Reference Figure 2 The dispersion component 5 includes a dispersion plate 51 and a plurality of dispersion rods 52. The dispersion plate 51 abuts against the buffer plate 4, and each dispersion rod 52 is evenly arranged along the circumference of the dispersion plate 51 on the side of the dispersion plate 51 away from the buffer plate 4.

[0039] Furthermore, a number of connecting blocks 511 are fixed on the dispersing plate 51, each connecting block 511 corresponding to a dispersing rod 52, and each dispersing rod 52 is provided with a connecting groove 521, with the connecting block 511 positioned in the corresponding connecting groove 521. The connecting block 511 provides a limiting position for the dispersing plate 51, making it difficult for the dispersing plate 51 to separate from the dispersing rods 52.

[0040] When the manhole cover body 2 is impacted, the dispersion plate 51 transmits the impact force from each dispersion rod 52 to the support plate 11, making it difficult for the impact force to concentrate in the manhole cover body 2, thus realizing the function of dispersing the impact force.

[0041] Reference Figure 1 The manhole cover body 2 is provided with several friction-enhancing protrusions 21, which improves the friction of the manhole cover body 2 and reduces the phenomenon of vehicles or pedestrians slipping when passing over the manhole cover body 2. In addition, in order to facilitate the movement of the manhole cover body 2, several lifting holes 22 are provided on the manhole cover body 2.

[0042] The implementation principle of a flexible manhole cover for municipal asphalt pavement in this application embodiment is as follows: When the manhole cover body 2 is subjected to external impact force, the buffer plate 4 and the support pad 3 absorb part of the impact force. The dispersion component 5 simultaneously disperses the impact force received by the manhole cover body 2, reducing the concentration of impact force at the manhole cover body 2, improving the elastic deformation capacity and fatigue resistance of the manhole cover body 2, making the manhole cover body 2 less prone to damage, thereby improving the overall service life of the manhole cover.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
