Anti-knock type mounting device used for manhole cover

Abstract

The invention discloses an anti-knock type mounting device used for a manhole cover. The device comprises a manhole opening (110) formed in the top end of a manhole (100) and a manhole cover (2) matched with the manhole opening (110) for connection. A bearing cross beam column (1) is transversely arranged at the position, located below the manhole opening (110), in the manhole (100), a bearing component (3) with a hollow containing cavity (30) inside is arranged in the bearing cross beam column (1), and two deformable fixing arms (21) which are distributed in a bilateral symmetry manner are integrally arranged at the bottom of the manhole cover (2) and are used for being inserted into the hollow containing cavity (30) of the bearing component (3) through elastic deformation.

Description

technical field [0001] The invention relates to the field of manhole cover connections, in particular to an anti-seismic installation device for manhole covers. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection shaft, and the inspection shaft mouth is usually flush with the ground, so a cover is needed to cover the inspection shaft cover of the inspection shaft. The existing inspection shaft covers are usually made of reinforced cement, metal, reinforced plastics and other materials. The inspection well mouth is matched, because the inspection well cover is made of metal material, and there is no fixed device to fix it, usually encounters the patronage of thieves, once the thief steals the insp...

[0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. It is called the inspection shaft, and the inspection shaft mouth is usually flush with the ground, so a cover is needed to cover the inspection shaft cover of the inspection shaft. The existing inspection shaft covers are usually made of reinforced cement, metal, reinforced plastics and other materials. The inspection well mouth is matched, because the inspection well cover is made of metal material, and there is no fixed device to fix it, usually encounters the patronage of thieves, once the thief steals the inspection well cover, it is easy to cause accidents, such as pedestrians falling into the inspection well Waiting for an accident
