Abstract

The invention discloses a device for the stable and quick hooking operation of a cable crane, and the device comprises a starting apparatus, a PLC controller, a relay apparatus, and an indication apparatus. A central control system provides a speed reference given signal and a weight signal of a lifted object as the reference variables of a specific speed curve. The device outputs a speed output signal to a drive mechanism according to an algorithm and a time sequence, which are preset according to the specific speed curve. The device can automatically judge the start process, can automatic increase and decrease the speed based on the given speed and correlated parameters, can enable the cable crane to be started quickly and stably, and inhibits the jump of a carrier cable.

Description

technical field [0001] The invention belongs to the field of electrical control of cable cranes, and in particular relates to a stable and fast hooking device for cable cranes. Background technique [0002] The medium and large hydropower stations that have been constructed in my country mainly use cable cranes for construction. The cable cranes are currently the world's largest and most efficient high-speed construction equipment. Cable cranes play a key role in the pouring construction of hydropower stations. The cable machine transmits the driving force through the cableway. Due to the flexibility of the cableway, any addition or subtraction of the driving force will have an impact on the cableway system, causing the bouncing and vibration of the carrying cable; frequent bouncing and bending will easily cause damage to the carrying cable. The service life of the load-carrying cable has a certain impact, which will have an extremely adverse impact on equipment maintenance ...
