Ship deck crane steel wire rope installation process method

Abstract

The invention discloses a ship deck crane steel wire rope installation process method. The method comprises the following steps that a, a traction nylon rope is installed; b, mounting a first traction steel wire rope; c, mounting a second traction steel wire rope; d, hoisting and placing the main steel wire rope transportation winding drum on the second rope winding machine by using a sea crane until a shaft of the second rope winding machine is completely inserted into a central hole of the main steel wire rope transportation winding drum, clamping and locking, switching on a power supply, debugging the second rope winding machine, and checking whether the second rope winding machine is normal or not; e, the PW125 connector is welded to the end of the main steel wire rope, and NDT flaw detection is conducted after welding; f, mounting a main steel wire rope; g, a main steel wire rope entering point is found, the end of the main steel wire rope is placed in a winding drum rope pressing end hole of the rope storage winch, and a bolt is screwed for fixing; h, loosening the main steel wire rope clamp, and continuously winding the main steel wire rope until the main steel wire rope on the main steel wire rope conveying drum is completely separated; i, pouring rope joints; and j, mounting a main hook. The method successfully solves the problem that the crane steel wire rope is difficult to install.

Description

technical field [0001] The invention relates to a process method for installing a steel wire rope of a ship deck crane. Background technique [0002] "Maersk Installer" is currently the world's latest ultra-deep-water offshore work vessel. The deck is equipped with two internationally leading new folding-arm offshore cranes with wave compensation function, including the traction winch and rope storage winch of the 400-ton folding-arm crane Arranged inside the cabin, supply and install during the ship construction stage, the main steel wire rope is supplied separately by foreign manufacturers, the delivery time lags behind, and the main steel wire rope is heavy (about 264 tons), and the 200-ton gantry crane on the berth does not meet the lifting requirements. It is impossible to install the main wire rope during the construction of the berth. According to the delivery date of the equipment, after the ship is built and launched, the 400-ton folding arm crane is installed under...

[0002] "Maersk Installer" is currently the world's latest ultra-deepwater offshore work vessel. The deck is equipped with two internationally leading new folding-arm offshore cranes with wave compensation function, including the traction winch and rope storage winch of the 400-ton folding-arm crane Arranged inside the cabin, supply and install during the ship construction stage, the main steel wire rope is supplied separately by foreign manufacturers, the delivery time lags behind, and the main steel wire rope is heavy (about 264 tons), and the 200-ton gantry crane on the berth does not meet the lifting requirements. It is impossible to install the main wire rope during the berth construction stage. According to the delivery date of the equipment, after the ship is built and launched, the 400-ton folding arm crane is installed underwater and then the main wire rope is threaded and installed. Because the crane wire rope cannot be directly installed on the rope storage winch Therefore, a deck crane wire rope installation process solution is needed to solve this construction problem
