Loading platform of mining elevator

Provided is a loading platform of a mining elevator and loading method thereof. The loading platform of the mining elevator comprises a power system and a loading device in a four- connection-rod structure. A rotation rod connected with the power system is arranged on the loading device. The power system comprises an explosion-proof electric machine, an upper limit switch, a lower limit switch and a head pulley. The explosion-proof electric machine is connected with the head pulley through a main steel rope, and a baffle plate is arranged on the main steel rope. A double-rope groove is arranged on the head pulley, and the head pulley is connected with a secondary pulley through a secondary steel rope. A sliding plate is arranged on the secondary steel rope, and a sliding rod is arranged on the sliding plate. The explosion-proof electric machine drives the main steel rope so as to drive the head pulley to rotate and then drive the secondary pulley to rotate. By moving up and down, the sliding plate enables the sliding rod to move in a bar-shaped notch sliding groove of a rotation rod so as to drive the rotation rod and the loading plate to do circumference motion. A connection rod drives a swing rod to rotate around a support frame. Reliable loading of a lap-joint platform in multiple planes is achieved. The loading platform is simple in structure, accurate in control, convenient to mount and maintain, and stable and reliable in operation, and has a self-locking function.
