In order to further improve the space utilization, the rail coil transport car is deployed in the underground transportation, which can significantly save the ground space. However, this measure also brings new challenges, that is, the help of the elevator is needed to realize the transfer of the coil transport car between the ground and the underground passage. When the elevator undertakes the transportation task of the coil transport car and the steel coil, safety protection is very important. In order to prevent the position of the coil transport car from deviating due to sudden conditions during lifting, and then causing serious operation accidents such as center of gravity imbalance and even falling from the lifting trolley, a reliable wheel locking device must be equipped to lock the H type rail wheel of the coil transport car on the lifting trolley of the elevator.
