Abstract

The invention relates to a road well lid opening device. Aiming at the technical problems in the opening process of a traditional road well lid, the invention provides the road well lid opening device. The device comprises a prizing rod; and a handle is arranged at the tail end of the prizing rod. The device is characterized in that a well lid grabbing device is arranged on the prizing rod; the well lid grabbing device can control a reserved hole for accessing a well lid through a clutch device; after an user enters the reserved hole, a lever of the prizing rod is kept away to upwards open the well lid; and meanwhile, the grabbing device can be taken out from the reversed hole through the clutch device. The road well lid opening device has the beneficial effects of: simple structure, convenience in manufacturing, capability of quickly realizing the well lid opening operation and great improvement of the working efficiency.

Description

technical field [0001] The invention relates to an opening device for a road manhole cover. Background technique [0002] At present, a large number of various pipelines adopt the mode of underground routing, and a wellhead for routing and maintenance is provided on the pipeline culvert, and a well cover is placed on the wellhead. The current manhole covers are mostly made of metal or other composite materials, and opening holes are reserved on the manhole covers. When opening the manhole covers, the operators mostly use ordinary metal hooks to open them. During the construction process, the manhole cover is often bonded by road materials such as concrete and asphalt, and it needs to pay a lot of labor intensity to realize it during the opening process. At present, there is no corresponding special manhole cover opening device for operation. Contents of the invention [0003] Aiming at the technical problems existing in the opening process of the current road manhole cove...
