Abstract

The embodiment of the invention discloses an opening device, wherein comprises a supporting frame, a lifting device and a hoisting device, wherein the supporting frame is used for supporting the lifting device connected with the supporting frame; the lifting device is fixedly arranged on the supporting frame and is used for lifting and supporting the hoisting device arranged on the lifting device to a high position; the hoisting device is arranged on the lifting device and is used for connecting a cover; the lifting device lifts the hoisting device; the hoisting device drives the cover connected with the hoisting device to move and open the cover. The cover is connected with the hoisting device, the hoisting device is supported to a high position by the lifting device, and meanwhile, the hoisting device drives the cover to move so as to open the cover. The opening device can be used for quickly opening a stuck, rusty or heavy cover, the working efficiency of opening the cover is effectively improved, and efficient and quick maintenance requirements of an underground pipeline can be conveniently met.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an opening device for an inspection well cover. Background technique [0002] In order to facilitate detection, exploration and maintenance of municipal underground pipelines, inspection wells (also known as cellar wells) are usually set on the road surface, and a cover is set on the inspection well, and the cover is closed on the inspection well. Remove from the surface and enter the manhole for municipal underground line maintenance. [0003] Usually, in order to achieve the effect that the cover is firm and anti-theft, the quality of the produced cover is heavy and the installation is tight (so that the cover is not easy to get out of the inspection well). During use, the gap between the inspection well and the cover is often filled with impurities or dust. If it accumulates for a long time, it may cause the cover to be stuck or rusted, making it difficult to open the cover...
