Problems solved by technology

[0002] The underground comprehensive pipe gallery requires special anti-theft manhole covers to be installed at the manholes on the top plates of nodes such as feeding ports and air vents. However, the existing urban underground pipe gallery manhole covers are relatively heavy, and people can only open them manually, which is very laborious. It is convenient for personnel to enter and exit and escape, and the existing manhole covers are relatively traditional, without intelligent control systems, remote control, and remote control, which are relatively rigid

Abstract

The invention discloses a hydraulic lifting well lid. The well lid comprises a well lid frame, a well lid cover plate, a hydraulic cylinder push rod mechanism, an electric hydraulic pump module, a manual hydraulic pump module and a control box, the well lid cover plate is hinged to the well lid frame up and down, the hydraulic cylinder push rod mechanism comprises a hydraulic cylinder and a telescopic rod, the hydraulic cylinder is fixed on the well lid frame, one end of the telescopic rod is installed in the hydraulic cylinder, the other end of the telescopic rod is connected to the well lidcover plate, the electric hydraulic pump module and the manual hydraulic pump module are connected to the hydraulic cylinder in parallel through pipelines, a travel sensor is arranged on the hydrauliccylinder, and the electric hydraulic pump module and the travel sensor are both in communication connection with the control box. The hydraulic lifting well lid has the integrated functions of beingautomatically opened and closed through remote operation, being opened and closed through remote control, being opened and closed through local operation, being opened, closed and cut off the power source through an external connection with a hydraulic pump, achieving the manual opening of a well lid for escape, being anti-theft and being waterproof.

Description

technical field [0001] The invention relates to the technical field of urban underground comprehensive pipe gallery, in particular to a hydraulic lifting manhole cover. Background technique [0002] The underground comprehensive pipe gallery requires special anti-theft manhole covers to be installed at the manholes on the top plates of nodes such as feeding ports and air vents. However, the existing urban underground pipe gallery manhole covers are relatively heavy, and people can only open them manually, which is very laborious. It is beneficial for personnel to enter and exit and escape, and the existing manhole covers are relatively traditional, do not have an intelligent control system, cannot be remotely controlled, and cannot be remotely controlled, so they are relatively rigid. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a hydraulic lift manhole cover, which can be opened and...
