The invention discloses a loosening device for an underground well lid of a municipal road. The loosening device comprises a main body shell. According to the loosening device, a gear and worm principle is utilized, and the underground well lid can be cyclically and effectively loosened so that the underground well lid can be opened under the condition that the damage degree is low; moreover, thedevice is provided with a certain mechanical protection mechanism so that the well lid can be effectively protected in the working process on the premise of independence, and the phenomenon that the well lid is damaged due to excessive looseness is prevented; furthermore, the device is provided with an annular array spring compression abutting type rotation force control mechanism so that the maximum force during rotation can be controlled, and the phenomenon that a driving motor is damaged due to excessive rotation resistance is prevented; and in addition the device is provided with a reversethread structure rotary longitudinal height adjusting mechanism so that the tension degree between components can be adjusted, and then the device can effectively improve the working efficiency.

    本发明公开了一种市政道路地下井盖用松动装置,包括主体外壳。本发明利用齿轮握杆原理,能够将地下井盖进行循环且有效的松动,从而使得地下井盖能够在受损程度低的情况下,打开,并且,该装置具有一定的机械保护机构,能够在独立的前提下,对井盖在工作过程中进行有效的保护作用,防止出现,松动过度而导致的井盖受损现象的发生,而且,该装置具有环形阵列弹簧压缩抵触式旋转力度控制机构,能够控制旋转时的最大力度,防止旋转阻力过儿而导致的驱动电机损伤现象的发生,此外,该装置具有反向螺纹结构旋转式纵向高度调节机构,能够调节部件之间的紧张程度,从而使得该装置能够在有效程度上的工作效率。
