Automatic opening-closing hydraulic pipe gallery well lid

Abstract

The invention provides an automatic opening-closing hydraulic pipe gallery well lid. The well lid comprises a well lid base, a plug pin, a well lid body, a rotation wheel, a hydraulic rod, a hydraulic power device and a draw cord; the edge of the well lid body is hinged to the well lid base, the plug pin is movably arranged on the inner side of the well lid body and can be locked on the well lid base in an inserted mode, and the rotation wheel is hinged to the inner side of the well lid body; the hydraulic rod is hinged to the rotation wheel, the draw cord connects the plug pin and the rotation wheel, the hydraulic rod is fixedly connected to the hydraulic power device, and the rotation wheel rotates to pull the draw cord, so that the plug pin is pulled out from the well lid base. The pipe gallery well lid achieves the function of automatic opening and closing of the well lid, is locked more firmly and more reliably, is opened conveniently and smoothly and promotes the construction and development of an intelligent city; meanwhile, the well lid is small in occupied space and suitable for remotely monitoring a well lid hydraulic pump, achieves intelligent operation and greatly saves labor cost.

Description

technical field [0001] The invention belongs to the field of municipal pipe gallery infrastructure, and in particular relates to an automatically opened and closed electro-hydraulic push rod type pipe gallery manhole cover. Background technique [0002] The manhole cover of the pipe gallery is the closure on the top of the entrance and exit to the underground facilities. Inspection wells need to be installed in places where tap water, cable TV, drainage, telecommunications, mobile, China Unicom, electricity, gas, heat, fire protection, sanitation and other public facilities are installed. You need a pipe gallery manhole cover. Especially in recent years, the state has increased investment in infrastructure and the development of urbanization. The state has invested heavily in public facilities. Urban renovation and new wires, cables, and optical cables have been changed from open air to underground. Therefore, there is a demand for pipe gallery manhole covers The volume inc...
