A hydraulic manhole cover for comprehensive pipe gallery

Abstract

The invention discloses a hydraulic well lid for a comprehensive pipe rack, and belongs to the technical field of municipal administration path infrastructures. The hydraulic well lid comprises a well lid body, a rotation shaft connected with the well lid body, guiding mechanisms connected with the rotation shaft, a hydraulic system connected with the guiding mechanisms and a control system connected with the hydraulic system. Each guiding mechanism comprises a guiding platform, a fixed platform, a stroke control rod, a hydraulic rod and a chain with one end fixed to the well lid body, wherein the stroke control rod is parallel to the hydraulic rod, one end of the stroke control rod is fixed to the guiding platform, and the other end of the stroke control rod is movably connected to the fixed platform. The control system is provided with a travel switch. The stroke control rods are matched with the travel switch to control the opening state of the well lid body. The well lid body is provided with penetrating communication holes. The communication holes communicate with the hydraulic system through hydraulic pipes. The hydraulic well lid has multiple opening modes, opening is convenient, and the hydraulic well lid has the beneficial effects of being safe, capable of preventing burglary and damage and convenient to manage and is suitable for the urban comprehensive pipe rack.

Description

technical field [0001] The invention relates to a hydraulic well cover for a comprehensive utility gallery, belonging to the technical field of municipal road infrastructure. Background technique [0002] The comprehensive pipe corridor, also known as the common ditch, is a comprehensive corridor of underground urban pipelines. It is an important infrastructure that integrates various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage, etc. to ensure urban operation. It can not only greatly facilitate the maintenance and repair of municipal facilities such as electricity, communication, gas and water supply and drainage. In addition, the system also has a certain effect of earthquake prevention and disaster reduction. The manhole cover is an important part of the comprehensive pipe gallery. Since various pipelines are traditionally buried independently in my country, the construction of the comprehensive pipe gallery is relati...
