Abstract

The invention discloses a special tool for opening a well cover and a method for opening a well cover using the tool, comprising a base, a lever, a prying part and a compression spring. The left end of the lever is hinged with the left end of the base, and the middle part is close to the left end. , connected by a compression spring, a certain angle is formed between the lever and the base; a universal wheel is provided at the bottom of the base close to the compression spring, and the prying part is arranged at the bottom of the lever through a connecting rod, It can be inserted into the special-shaped hole of the well cover; through the present invention, the well cover can be opened very labor-savingly, and the influence of harmful gas in the well on the health of workers can be reduced, and electric shock accidents can be avoided.

Description

technical field [0001] The invention belongs to the technical field of well cover construction, and in particular relates to a special tool for opening a well cover and a method for opening a well cover using the tool. Background technique [0002] Manhole covers are mainly used to cover deep wells in roads, construction and other projects, and to prevent people or objects from falling. They are also common in our daily life. Manhole covers can be used to cover various deep wells such as electric wells, gas wells, natural gas wells, tap water wells, gas station underground wells, etc., and are widely used. [0003] When overhauling or inspecting the well condition, the manhole cover needs to be opened first. At present, the main way to open the manhole cover is to open the manhole cover with bare hands or with a hook. The gaps between the wells are filled with dust and debris, which makes it difficult to open the traditional manhole covers. In particular, in order to fix th...
