Description
Technical Field
[0001] The utility model relates to the technical field of instrument maintenance, in particular to a device for opening an instrument well cover. Background Art
[0002] In steel enterprises, instrument wells are used to install flow detection instruments. Instrument wells are covered with manhole covers to prevent pollution risks and safety hazards. When inspecting the inside of the instrument well and inspecting, repairing, and weekly testing the instrument equipment in the well, the manhole cover at the mouth of the instrument well needs to be removed. The traditional way to open the manhole cover is to first pry up the manhole cover from the edge with a pickaxe or a crowbar, then use a pry hook to drag a part of it to the ground, and 2-3 people lift the manhole cover to one side. Opening the manhole cover is labor-intensive, time-consuming, and labor-intensive. In particular, instrument wells are spread throughout the enterprise. Due to the influence of bad weather, a large amount of soil accumulates in the gaps of the manhole covers. Even worse, when they are in disrepair, the impact on the opening of the manhole cover is more serious.
[0003] A part of the existing manhole cover opening device still relies on manpower to open the manhole cover using the lever principle, while the other part can open the manhole cover without manpower through electrical control. However, such devices are generally large in size, which makes them inconvenient to carry, and are not suitable for the location of the manhole cover. Therefore, the current manhole cover opening device still has the problems of being inconvenient to use, time-consuming and labor-intensive. Utility Model Content
