Safe and intelligent hydraulic manhole cover for comprehensive pipe rack

Abstract

The invention relates to a safe and intelligent hydraulic manhole cover for a comprehensive pipe rack. The safe and intelligent hydraulic manhole cover comprises a manhole cover body, a shaft lining,double-shaft lugs I, a T-shaped thread groove, a wide shaft lug, a handle, a heat detector, a double-guide sleeve fixing plate, a fixed support, a pressure switch, a guide sleeve, guide locating rods,a fixed plate, a double-lug seat, a hydraulic cylinder, a double-shaft lug II, a fixing sleeve, a proximity switch, a bidirectional hydraulic lock, an external manually opened oil pipe, an external manually closed oil pipe, a hydraulic cylinder rodless oil supply and return pipe, a hydraulic cylinder sucker rod oil supply and return pipe, an arc-shaped light curtain, a support rib plate, a sealing ring, a mounting part, a locating plate and a shaft lug support plate. The safe and intelligent hydraulic manhole cover is simple in structure, convenient to install and smooth in opening and closing, and can realize intelligent opening and closing control in multiple modes; the safe and intelligent hydraulic manhole cover is provided with multiple stages of safety control devices, so that the safe opening and closing the manhole cover is guaranteed; the safe and intelligent hydraulic manhole cover is larger in well mouth space under the condition of the same outline dimension.

Description

Technical field: [0001] The invention belongs to the technical field of intelligent manhole covers, and in particular relates to a safe and intelligent hydraulic manhole cover for a comprehensive pipe gallery. Background technique: [0002] The comprehensive pipe gallery is a modern facility that integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage. The hydraulic manhole cover of the pipe gallery is an inspection facility for the comprehensive pipe gallery and is an important part of the comprehensive pipe gallery. It has the functions of maintenance access, emergency exit, fire prevention, waterproof, and anti-theft. With the vigorous development of domestic comprehensive pipe gallery, that is, the comprehensive corridor of underground urban pipelines, the number of hydraulic manhole covers used in comprehensive pipe gallery has increased sharply, but the hydraulic manhole covers currently used in urban compreh...

AI Technical Summary

Problems solved by technology

With the vigorous development of domestic comprehensive pipe gallery, that is, the comprehensive corridor of underground urban pipelines, the number of hydraulic manhole covers used in comprehensive pipe gallery has increased sharply, but the hydraulic manhole covers currently used in urban comprehensive There are more or less deficiencies in the above, such as unsteady opening and closing of the manhole cover, personal injury caused by no protection control, inflexible opening and closing of the manhole cover, insufficient opening and closing of the manhole cover, small wellhead space, etc.
