Problems solved by technology

During the use of the existing cable trolley system, the cable trolley often jams. After the cable trolley is jammed, if the cage continues to run upwards, the accompanying cable will be broken. If the cage continues to go down Running will hit the cable trolley and cause the safety hazard of damage to the cable trolley

Abstract

The invention belongs to the technical field of building machine equipment, and particularly relates to a cable pulley system with a construction lifter with fault detecting and automatic protection functions. The cable pulley system comprises a fixing device, a cable pulley, a fault detecting and protecting device, a traveling cable and a traction steel wire rope; the fixing device is fixedly connected to the high position of a guide rail support, the fault detecting and protecting device is fixed to a hoisting cage, one side of the cable pulley is provided with a cable sliding wheel and a steel wire rope sliding wheel, one end of the traveling cable and one end of the traction steel wire rope are both fixed to a fixing frame, the other end of the traveling cable is loose to be wound around the cable sliding wheel to be fixed into the hoisting cage, and the other end of the traction steel wire rope is wound around the steel wire rope sliding wheel to be connected with a loading pull rod of the fault detecting and protecting device. The cable pulley system is simple in structure, novel in design, complete in function and high in using reliability, and the using safety and reliability of the construction lifter can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and equipment, in particular to a cable pulley system with fault detection and automatic protection for a construction hoist. Background technique [0002] The construction hoist is a kind of hoisting machine for vertically transporting personnel and materials in building construction. It is mainly composed of hoist rail frame, cage and drive system, safety device, power supply and cable guide device, etc. Considering the self-weight and voltage drop of the cable, when the guide rail frame of the construction hoist exceeds a certain height, it is generally required to be equipped with a cable pulley type cable guide system. Among them, the existing cable trolley system is mainly composed of accompanying cables, cable trolleys, fixing devices, and cable protection devices. Finally, it is fixed on the cage; when the construction elevator cage runs up and down, the cable block can mov...
