Abstract:The internal drag system of the auxiliary well cage and the cart system of each middle section of the dock door are improved to realize the operation of pushing and pulling the mine carts for the removal of the wellhead and underground carts to achieve the purpose of reducing staff and increasing efficiency. The technical scheme of interlocking the cart and pushing the claw into the tank is adopted in the cage, and adjustments are made to the rocking platform of each mid-section dock door and cage guide plate. Push claws are used to drive each chain link to connect the mine cart into the tank at each middle section of the underground mine. When the rocking platform is in place, the proximity switch control and signal system are used for interlocking to ensure the safe operation of the cage. From the perspective of the improved lifting operation, the dismantling of the cart does not affect the efficiency of the cage, and the scheme of using the linkage to block the cart and the cart into the tank fully meets the various technical indicators.
