The invention discloses an opening device applicable to multiple types of well lids. The opening device applicable to the multiple types of the well lids comprises a bearing cross beam frame, wherein the bottom of the bearing cross beam frame is provided with a roller, and the rear end of the bearing cross beam frame is provided with a handrail; a notch is formed in the front end of the bearing cross beam frame, and a fixed pulley ratchet mechanism is arranged on the bearing cross beam frame close to the back of the notch; the fixed pulley ratchet mechanism comprises a left fixing support and a right fixing support, a rotating shaft is arranged between the left fixing support and the right fixing support, the rotating shaft on the inner side of the left fixing support is sleeved with a fixed pulley, the rotating shaft on the outer side of the left fixing support is sleeved with a hand rocker, the rotating shaft on the inner side of the right fixing support is sleeved with a ratchet wheel, and a pawl is hinged to the upper portion of the ratchet wheel on the inner side of the right fixing support; the fixed pulley is connected with a plurality of steel wire ropes which penetrate through the notch in the front end of the bearing cross beam frame to naturally fall, and lifting hooks are arranged at falling tails of the steel wire ropes correspondingly. The opening device applicable to the multiple types of the well lids is simple in structure, flexible and changeable, and the problems that the well lids opening wastes time and labor and is low in efficiency can be effectively solved.
