Abstract
The invention discloses a mine draw shaft safety protection structure. The mine draw shaft safety protection structure comprises a fixed support arranged above the outer side of a draw shaft opening. An oil cylinder support is arranged on the draw shaft opening below the fixed support. The fixed support is hinged to the head end of a main beam. An upper oil cylinder is hinged between the front section of the main beam and the oil cylinder support. The rear section of the main beam abuts against the top edge of the draw shaft opening and stretches into the draw shaft opening. The tail end of the main beam is hinged to the head end of an auxiliary beam. The tail end of the auxiliary beam abuts against the bottom surface of the draw shaft opening. A lower oil cylinder is hinged between the auxiliary beam and the rear section of the main beam. An upper cover plate is arranged above the rear section of the main beam. A rear cover plate is arranged on the inner side of the auxiliary beam. The mine draw shaft safety protection structure can be installed on the draw shaft opening, workers do not need to enter a draw shaft to conduct operation, potential safety hazards are avoided, and safety protection is provided for maintenance of a draw shaft ore drawing device; multi-point fixation is adopted, and therefore stability and stability of the whole structure are improved; the mine draw shaft safety protection structure is convenient and quick to use, a great amount of maintenance time can be saved, and labor intensity is relieved.
