TECHNICAL FIELD
[0001] The present application relates to the field of side loading devices, in particular to a marine oil platform offshore equipment side loading device. BACKGROUND
[0002] The marine oil platform is built on land in a manner similar to building with blocks. Generally, mechanical equipment is hoisted to a coordinate position for installation before the upper deck piece is installed. However, due to delayed delivery of mechanical equipment and a tight platform construction period, there are cases where the equipment installation time is later than the upper deck piece installation time. Due to the obstruction of the upper deck piece, the equipment cannot be directly hoisted into place. Therefore, the construction team usually builds a side loading platform on the ground next to the platform on the outside of the platform. The equipment is hoisted onto the side loading platform and pulled and slid to the coordinate position for installation using auxiliary tools such as a chain and a slide rail. The above process is defined as "side loading", and the side loading platform is a key device in the side loading process. The side loading platform is usually composed of a platform welded by H-shaped steel of a certain specification, and a round steel pipe as a leg standing on the ground. In addition to the equipment side loading during the land construction of the marine oil platform, there are also cases of offshore side loading of some equipment. Unlike the construction of the side loading platform during the land construction process, the construction of the offshore side loading platform often uses a diagonal brace welded to the oil platform as a leg, and the side loading platform is welded to the oil platform next to it. This process not only has high difficulty and risk, but also requires the construction of a large number of scaffolds for assistance. After the offshore side loading is completed, the side loading platform, the diagonal brace, and the damaged paint surface need to be cut and removed, and a large number of scaffolds also need to be removed, all of which have high operation risk and large workload.
[0003] During side loading, there is a problem that the side loading platform is not convenient to quickly disassemble and assemble. In view of this, a marine oil platform offshore equipment side loading device is provided. SUMMARY
