A kind of transportation technology of riprap leveling ship pile leg barge

Abstract

The invention relates to a spud leg barge transportation process of a riprapping leveling ship. The spud leg barge transportation process includes the steps of making a preparation, wherein four spud legs are transported to a to-be-loaded barge beside a wharf; parking a transportation barge on the wharf and cleaning the deck of the barge; arranging bed jigs, wherein the four spud leg transportation bed jigs are sequentially arranged on the barge in advance, a barge-passing steel plate is laid between the wharf and the barge, and it is ensured that the central line of the barge-passing steel plate is flush with the central line of the barge; loading the spud legs, wherein the spud legs are transported onto the barge in a linkage mode through a flat car, and the spud legs are tied firmly; unloading the spud legs, wherein after arriving at a target wharf, tying pieces are removed, it is ensured that the barge is flush with the wharf, the steel plate is laid, the spud legs are transported through the flat car, and the flat car keeps synchronously transporting the spud legs to a destination during transportation. The spud leg barge transportation process has the advantages that by means of the method of arranging the transportation beg jigs in a staggered mode and the method of cutting and reinforcing the transportation beg jigs, no large barge needs to be used, and the transportation reliability and convenience of the barge are ensured.

Description

technical field [0001] The invention relates to the technical field of a riprap leveling ship, in particular to a riprap leveling ship leg barge transportation process. Background technique [0002] The lifting mechanism of the riprap leveling vessel and the jack-up drilling platform is a heavy-duty open rack and pinion transmission structure. According to the pile leg requirements of the jack-up drilling platform, the number of pile insertion / extraction on the platform shall not exceed 5 times a year; while the lifting mechanism operates frequently, the rack and pinion are in low-speed, heavy-load, and impact conditions for a long time, and piles are frequently inserted and pulled under high load The wear of gear and rack is accelerated by operation; after testing, the wear value of local leg rack has exceeded the design allowable value. The amount reaches 15mm (maximum allowable 5mm). In view of the wear and tear of the pile legs, it is imperative to replace and repair th...

Problems solved by technology

According to the pile leg requirements of the jack-up drilling platform, the number of pile insertion / extraction on the platform shall not exceed 5 times a year; while the lifting mechanism operates frequently, the rack and pinion are in low-speed, heavy-load, and impact conditions for a long time, and piles are frequently inserted and pulled under high load The wear of gear and rack is accelerated by operation; after testing, the wear value of local leg rack has exceeded the design allowable value. The amount reaches 15mm (maximum allowable 5mm). In view of the wear and tear of the pile legs, it is imperative to replace and repair the pile legs. However, the length of the pile legs is long and the number is large, which has great requirements on the width of the transport barge. Transportation has become a problem
