An assembled fall buffer type stainless steel manhole cover and its assembly method

Abstract

The invention discloses an assembled fall-buffering stainless steel manhole cover and an assembly method thereof, belonging to the technical field of stainless steel manhole covers, comprising a well base laid at the wellhead of a sewer, a well sleeve fixed on the edge of the well base, and a well cover embedded in the well sleeve Assemblies, a buffer assembly is installed on the well cover assembly, and the buffer assembly is used for buffering and assembling the well cover assembly. The invention proposes an assembled fall buffer type stainless steel manhole cover and its assembly method. The buffer rod rotates around the rotation axis until the locking rod is inserted into the locking hole, the semicircular upper plate and the semicircular lower plate are assembled, and the upper cylinder, the lower cylinder and the first When the spring is set, when the upper cylinder and the lower cylinder are rotating, the first spring is compressed to the shortest position when the lower cylinder is rotated to the vertical state of the upper cylinder due to the action of the bottom wall of the slot hole of the semicircular lower plate , continue to move toward one side, the first spring will slowly stretch, so as to achieve the purpose of stretching or shortening, and the cushioning degree is improved by using the first spring and the second spring.

Description

technical field [0001] The invention relates to the technical field of stainless steel well covers, in particular to an assembled fall-buffering stainless steel well cover and an assembly method thereof. Background technique [0002] Under the status quo of rapid development, in order to meet the needs of people traveling, new road construction is essential, and it will bring underground water pipelines. In this process, it is necessary to build the connection area of ​​the pipeline on the road. Circular manholes are built on the road, and there are potential safety hazards in the circular manholes on the road; When the fit of the manhole is not tight and loose, the passing vehicles will vibrate the manhole cover and generate noise, which will affect people's quality of life. When this happens frequently, the manhole cover is easily damaged, posing a safety hazard. [0003] Existing manhole covers are generally not anti-seismic, and manhole covers are made of integral casti...

[0002] Under the status quo of rapid development, in order to meet the needs of people traveling, new road construction is essential, and it will bring underground water pipelines. In this process, it is necessary to build the connection area of ​​the pipeline on the road. Circular manholes are built on the road, and there are potential safety hazards in the circular manholes on the road; When the fit of the manhole is not tight or loose, the passing vehicles will vibrate the manhole cover and generate noise, which will affect people's quality of life. When this happens frequently, the manhole cover is easily damaged, posing a safety hazard

[0003] The existing manhole covers are generally not anti-seismic, and the manhole covers are made of integral casting, and when the integral casting falls, the manhole covers crack, which shortens the service life of the manhole covers
