Problems solved by technology
These well covers are basically made of metal materials such as cast iron and ductile iron, which have the characteristics of high strength and large bearing capacity, but at the same time, due to the heavy weight of the well covers, it is difficult to open the well covers. When the manhole cover is large in size and mass, manual operation is time-consuming and labor-intensive, and manual lifting of the manhole cover is likely to cause injury to workers, posing safety hazards

The invention discloses a labor-saving device for opening a well lid. The device comprises a main rod, a movable sleeve, a supporting rod and a pull rod; a first hook part is arranged at one end of the main rod; a pressing part is arranged at the other end of the main rod; a first hinge part is arranged on the main rod; the movable sleeve is connected with the main rod in a sleeving mode; the twoends of the main rod extend out of the movable sleeve; the extending length of the first hook part is smaller than the extending length of the pressing part; a second hinge part is arranged on the movable sleeve; the supporting rod is hinged to the second hinge part; one end of the pull rod is hinged to the first hinge part; and a second hook part is arranged at the other end of the pull rod and matched with the first hook part to be meshed with the well lid. According to the labor-saving device for opening the well lid, the well lid can be easily opened, so that time and labor are saved, thelabor intensity of workers can be relieved, and the labor-saving device is safe and reliable.
Description
technical field [0001] The invention relates to the technical field of construction tools, in particular to a labor-saving device for opening well covers. Background technique [0002] In today's municipal construction or community water supply and drainage construction, when laying water supply and drainage pipes, it is necessary to set up a maintenance well, and a manhole cover needs to be installed above the maintenance well. During the maintenance process, the operator needs to open the manhole cover. These well covers are basically made of metal materials such as cast iron and ductile iron, which have the characteristics of high strength and large bearing capacity, but at the same time, due to the heavy weight of the well covers, it is difficult to open the well covers. When the manhole cover is large in size and mass, manual operation is time-consuming and labor-intensive, and manual lifting of the manhole cover is likely to cause injury to workers, posing a safety haz...
