Abstract
The invention discloses a method and a special device for intelligently complementing expansion of a cage load steel wire rope. The method includes: (1) measuring the weight m1 of object to be conveyed through a weighter at a well mouth, and transmitting the weight m1 to a programmed logic controller (PLC); (2) loading the object to be conveyed on four supporting claws of a cage weighing supporting pot at a normal crawling speed, wherein the action force of the four supporting claws is acted on the weighter through a frame or a buffering device, and then outputting the parameter m to the PLC through the weighter; (3) stopping a lifting machine when the PLC judges the parameter m to be equal to the m1, and the overloaded amount for lifting the steel rope wire is equal to the elastic expansion change amount for lifting the steel rope wire due to changes of the lifting weight. On the condition of maintaining an original cage load device not to change, the weighter is arranged at a side for a pit car to enter or a side for the pit car to go out of a well mouth. The load weight is measured through the weighter, and the weight value is transmitted to the PLC. A weight sensing device at the shaft bottom is maintained not to change. The method greatly reduces mine infrastructure workload and equipment investment cost, and has good practicability.
