The invention relates to an opening device of a well cover with a pair of apertures, which comprises a main cross beam and a pair of hinge wheel seat bodies arranged on two sides of the main cross beam, and is characterized in that: the hinge wheel seat bodies and the two side parts of the main cross beam are fit in a sliding mode for lifting; the hinge wheel seat bodies are also provided with a jack capable of jacking the main cross beam; the main cross beam is fixedly connected with a pair of suspenders capable of passing through the apertures of the well cover downwards; and the lower ends of the suspenders are connected with a section of a crank capable of passing through the apertures of the well cover. The device has the advantages of large well cover opening pull force, simple operation,high operation safety, wide adaptability and convenient carrying and transport.
Description
technical field [0001] The invention relates to a manhole cover opening device with a pair of slit holes, which is suitable for opening the manhole cover. Background technique [0002] The application number is 200820039174.9, and the patent named Manhole Cover Opening Tool provides a manhole cover opening tool, which adjusts the position of the lead screw through the slider, lifts the manhole cover by manually pressing the pull rod, and relies on the roller at the lower part of the tool to transport, the patent In the middle, the tapered end of the front end of the lead screw is inserted into the hole of the manhole cover, and the movable piece is stretched outward, thereby hooking the manhole cover, and the manhole cover is lifted by manually pressing the tie rod. The structure is relatively complex and it is laborious to lift the manhole cover. Therefore, how to solve the above problems is the purpose of this research invention. SUMMARY OF THE INVENTION [0003] The pu...
