The invention discloses an integral hydraulic ascending and descending type complete set well lid which comprises an explosion-proof emptying valve, a one-way liquid inlet valve, an inside hollow round base, hydraulic oil, a sealing ring, a cavity, a ladder, an operation area, a vertical steel ring, a well lid and an upright post, wherein the upright post is welded inside the inside hollow round base; the inside hollow round base is respectively provided with the cavity and the operation area through the upright post; the explosion-proof emptying valve and the one-way liquid inlet valve whichpenetrate through the upright post are arranged on the upright post; the explosion-proof emptying valve and the one-way liquid inlet valve realize fluid communication with the cavity; the inside of the cavity is filled with the hydraulic oil; the vertical steel ring is welded on the well lid, and can be movably inserted and connected inside the cavity; and the cavity and the vertical steel ring realize the sealing through the sealing ring arranged on the vertical steel ring in a sleeved way. The effective height of inside compressed liquid is 40 cm; the well lid elevation can be effectively regulated; and the problem that most municipal well lids are higher than a pavement is solved.
Description
technical field [0001] The invention relates to the technical field of well covers, in particular to a complete set of integral hydraulic lifting type well covers. Background technique [0002] The current municipal road wells and manhole covers are mainly composed of masonry wells and cast iron manhole covers. For such wells and manhole covers, every time road maintenance and uneven settlement of the road will make the sewage wells and manhole covers above the ground, and the manhole covers are generally 5 to 5 above the ground. 10cm is very difficult to maintain and adjust. The most important thing is that the maintenance cost is high and the time is long, which seriously affects the traffic of road vehicles. During the maintenance process, being in the traffic flow for a long time will pose a huge threat to the personal safety of the operators. Contents of the invention [0003] The purpose of the present invention is to provide a whole set of hydraulic lifting type man...
