Description of the Invention: [Technical Field] The present invention is a driving force of a small boom with a truck mounted on a truck, driving two reverse lever type manhole cover shutters, simultaneously lifting and lifting Manhole cover, providing a simple and safe reverse lever type manhole cover opening and closing device 7 [Prior Art] The manhole cover plate on the road for a long time, because the heavy truck has a high speed rolling occasional jump 10 off the cover seat The dangerous situation arises. Therefore, an annular wing plate is specially formed on the lower edge of the manhole cover, and an annular groove is also formed in the base of the manhole cover, and the annular wing plate and the annular groove are used. The geometry allows the manhole cover to rise only vertically to prevent jumps caused by truck crushing. At present, there are two methods for opening and closing the manhole cover plate: (丨) Manual lever shutters. · After hooking the hook plate of the manhole cover with his hook, manually press the handle of the tail end to make the manhole After the cover is lifted, remove it from the manhole cover, and then pull the manhole cover away from the manhole cover. Since the weight of the manhole cover has reached 15 〇A kg or more, the two tributaries are not stuck in the manhole cover, and the operation is still too strong. If there is any partial jamming on the manhole cover, it is completely powerless. . (Please refer to Figure 1) (2) Small hangers for trucks: Use the two hooks of the slings to lift the manhole cover, then hang the hook of the boom, and lift the manhole cover with the tension of the boom It does not have to be laborious to operate, but as long as the manhole cover is stuck, it is not only impossible to hoist, but if it is strongly opened with a large pulling force, the local components may be destroyed and the danger may occur. (Please refer to !283276 Figure 2) The reasons for the difficulty in opening the manhole cover are as follows (Please refer to Figure 3) (1) The contact interface between the manhole cover and the manhole cover is often subject to sand and gravel sludge seepage. , _ enter, and get stuck. - - . 丨 -~, (2) The contact surface between the manhole cover and the manhole cover is eroded by rain, causing rust and increasing friction. • (3) The annular groove with the manhole cover and the annular groove of the manhole cover. Although the manhole cover is not easy to jump due to the rolling of the truck, it must be raised vertically to open, as long as it is not balanced. Ascending is stuck, increasing the difficulty of operation. It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good designer, but needs to be improved. In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in completing the '· this reverse lever type manhole cover opening and closing device. [Object of the Invention] An object of the present invention is to provide a reverse lever type manhole cover opening and closing device, which is capable of driving two reverse lever type manhole cover shutters by using a small turning force of a truck. Lift and hoist the manhole cover to provide a simple and especially safe method for opening and closing the manhole cover. SUMMARY OF THE INVENTION The reverse lever type manhole cover opening and closing device which achieves the above object of the invention utilizes two special-shaped reverse lever type manhole cover shutters for lifting the 1283276 hook bolt at the intermediate force point. Fixed on the manhole inspection, the front fulcrums each of the modulating bearing seats can reduce the horizontal friction of the fulcrum. The force point is connected by a sling to the hook of the small boom of the truck. When the sling is pulled up, the end of the reverse lever type manhole cover switch is on the top - - 歼 simultaneous reverse lever type The front end of the manhole cover shutter is pressed down, and the manhole cover is lifted by the principle of the lever. ▲ When the rear end of the reverse lever type manhole cover switch rises to a 45 degree angle, the manhole cover is removed from the manhole cover, and the angle of the reverse lever type manhole cover switch is It will not be added any more. Because the front end point of the reverse lever type manhole cover shutter is fixed, the entire manhole plate is aligned on both sides of the south side to meet the vertical opening mechanism of the manhole cover. The factor of the geometric shape between the manhole cover and the manhole cover can be completely avoided; and the friction between the two can be greatly overcome, achieving the purpose of simplicity, efficiency and safety. [Embodiment] The invention is a comprehensive improvement to replace the traditional manual manhole cover shutter with the pulling force of the vehicle boom, so that it has a simple, reliable and safe manhole cover.
