Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a triangular support manhole cover with high stability. Background Art

[0002] Manhole covers are generally used to cover roads to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Road manhole covers are generally required to have high compression, bending, impact resistance and toughness. After long-term use, the product will not cause the manhole cover to be crushed or damaged, which can completely prevent the occurrence of "urban black hole" accidents. It is easy to use and easy to transport, install and repair.

[0003] In order to reduce the noise generated by vehicles passing by, some existing municipal manhole covers usually use rubber gaskets to reduce the noise caused by the shaking between the manhole cover and the base. However, as the manhole cover ages, the rubber ring may age and crack due to being outdoors for a long time, resulting in a gap between the manhole cover and the base, and the manhole cover may also cause noise, vibration and other problems. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of some existing municipal manhole covers that usually use rubber gaskets to reduce the noise generated by the shaking between the manhole cover and the base in order to reduce the noise generated when vehicles pass by. However, as the manhole cover is used for a long time, the rubber ring may age and crack when it is outdoors for a long time, resulting in a gap between the manhole cover and the base. The manhole cover also has problems such as noise and vibration. A triangular support manhole cover with high stability is provided.

[0005] The purpose of the utility model is achieved through the following technical solutions: a triangular support manhole cover with high stability, comprising an upper manhole cover and a base, the upper manhole cover is installed on the upper part of the base, three groups of positioning grooves in a circular array are opened on the inner side of the base, and three groups of positioning plates in a circular array are installed on the outer side of the upper manhole cover, and the positioning plates are clamped with the positioning grooves. The upper manhole cover and the base can be clamped by setting three groups of positioning plates and three groups of positioning grooves. When a car passes over the upper manhole cover, the base can not only provide longitudinal supporting force to the upper manhole cover, but also the base can provide lateral clamping force to the upper manhole cover through the positioning grooves and the positioning plates, which can keep the upper manhole cover in a highly stable state in the base, so that it is not easy to generate a gap between the upper manhole cover and the base, avoiding the generation of vibration and noise.

[0006] A further technical solution is that a groove is opened on the base, and an ear plate is installed on the upper manhole cover. The ear plate is installed in the groove and is rotatably connected to the groove, and the upper manhole cover is rotatably connected to the base through the ear plate.

[0007] A further technical solution is that a fixing plate is installed on the bottom surface of the upper manhole cover, a plurality of groups of second reinforcing ribs in a circumferential array are installed between the outer circle of the fixing plate and the upper manhole cover, and a plurality of groups of first reinforcing ribs in a circumferential array are installed between the inner circle of the fixing plate and the upper manhole cover. By providing the first reinforcing ribs and the second reinforcing ribs between the upper manhole cover and the fixing plate, the bearing strength of the upper manhole cover can be effectively improved, making it difficult for the upper manhole cover to be deformed by force, thereby ensuring the durability of the upper manhole cover and avoiding the generation of noise caused by the gap between the upper manhole cover and the base due to the deformation caused by force.

[0008] A further technical solution is that a third reinforcing rib connected to the positioning plate is installed on the bottom surface of the upper manhole cover. By providing the third reinforcing rib, the strength of the positioning plate can be improved, thereby improving the strength between the positioning plate and the positioning groove, thereby ensuring the stability between the upper manhole cover and the base.

[0009] A further technical solution is that an opening groove is provided on the inner circle of the base, and the opening groove and the groove are symmetrical with respect to the base. The provision of the opening groove can facilitate the later opening of the upper manhole cover on the base for easy operation.

[0010] A further technical solution is that a shaft is installed on the bottom surface of the base, and a plurality of equidistant array mounting blocks are installed on the inner circle of the shaft. The installation blocks can facilitate the later installation of the anti-fall net and improve the safety of the base.

[0011] A further technical solution is that a fourth reinforcing rib connected to the wellbore is installed on the bottom surface of the base, and the fourth reinforcing rib is provided to activate the connection strength between the wellbore and the base, thereby improving the bearing capacity of the wellbore.

[0012] A further technical solution is that the upper surface of the upper manhole cover is provided with anti-skid patterns, and the anti-skid patterns are provided to improve the anti-skid performance of the surface of the upper manhole cover.

[0013] The utility model has the following advantages: the utility model can connect the upper manhole cover and the base by setting three groups of positioning plates and three groups of positioning grooves for locking each other. When the car passes over the upper manhole cover, the base can not only provide longitudinal supporting force to the upper manhole cover, but also provide lateral locking force to the upper manhole cover through the positioning grooves and the positioning plates, so that the upper manhole cover can maintain a highly stable state in the base, so that it is not easy to generate a gap between the upper manhole cover and the base, avoiding the generation of vibration and noise. By setting the first reinforcing rib and the second reinforcing rib between the upper manhole cover and the fixing plate, the bearing strength of the upper manhole cover can be effectively improved, so that the upper manhole cover is difficult to be deformed by force, thereby ensuring the durability of the upper manhole cover and avoiding the generation of noise caused by the gap between the upper manhole cover and the base due to force deformation.
