Abstract

The invention relates to a well cover opening auxiliary device, and belongs to the technical field of well cover opening. According to the technical scheme, the well cover opening auxiliary device comprises a support frame, a movable rod vertically arranged on the support frame, a lifting member with one end capable of extending into a well cover through hole to abut against the inner side of thewell cover and the other end rotationally connected to the end of the movable rod and rotating around the axis of the movable rod, and a lifting assembly installed on the support frame and used for driving the movable rod to ascend and descend and driving the lifting member to lift the well cover. When the auxiliary device is used, well cover opening can be facilitated, time and labor can be saved, and unnecessary troubles are reduced.

Description

technical field [0001] The invention relates to the technical field of manhole cover opening, in particular to an auxiliary device for opening a manhole cover. Background technique [0002] In daily life, you can often see all kinds of manhole covers on the road, and most of them are circular manhole covers. At present, the common circular manhole covers usually have two or more oval through holes on the manhole cover. When it is necessary to overhaul the sewer or the cable under the manhole cover, it is usually necessary to open the manhole cover. [0003] In the actual work process, opening the manhole cover is generally carried out manually. Generally, it is necessary to hold an iron bar or an iron hook, and insert the hooked end of the iron hook or iron bar into the oval through hole of the manhole cover, and then manually remove the manhole cover. Lift or tilt the manhole cover to open the bulky manhole cover. [0004] However, the current method of opening the manhol...
