Abstract

The invention discloses a mobile portable well cover opening device of a power distribution work well. The mobile portable well cover opening device comprises a rising mechanism, at least three supporting rods and at least one well cover clamping mechanism, wherein the rising mechanism is a spiral column with a thread on the surface; a connection piece is connected outside the spiral column in a threaded sleeving manner; the upper end of each supporting rod is fixedly connected to the connection piece, and a roller is arranged at the lower end of each supporting rod; the well cover clamping mechanism comprises a middle piece and a clamping piece; and one end of the middle piece is fixedly connected to the bottom of the spiral column, and the other end of the middle piece is fixedly connected with the clamping piece. The mobile portable well cover opening device of the power distribution work well has an effect of opening a well cover, and also saves the labor, improves the well cover opening efficiency, reduces damage to the well cover due to manual well cover opening, prolongs the service life of the well cover and brings obvious economic benefit.

Description

technical field [0001] The invention relates to the field of distribution network accessories, in particular to a movable and portable distribution manhole cover opening device. Background technique [0002] In recent years, with the expansion of the distribution network scale and the increase of maintenance tasks, the number of openings for distribution wells is also increasing. Present well cover opening method mainly is that the construction personnel utilizes the iron hook to open, and every time opening all causes the damage of varying degrees to the well cover. Due to frequent opening, the protective structure of some well covers is damaged and needs to be replaced frequently, which brings a lot of trouble to the safety of construction personnel and equipment. Therefore develop a kind of well cover that can realize conveniently opening well cover, reduce the damage to well cover as far as possible simultaneously, to prolong the well cover opening device of the service...
