Internal-external holding type conduit tube rack levelling device

Abstract

The invention provides an internal-external clamping type jacket leveling device, comprising an upper clamping mechanism, a middle lifting mechanism, a lower clamping mechanism and a scale mechanism; the middle lifting mechanism is arranged between the upper and lower clamping mechanisms; the upper clamping mechanism comprises a clamping body, a plurality of lifting lugs used for lifting and a plurality of clamping jaws and clamping pressure cylinders used for clamping the pile body are arranged on the clamping body, and the clamping jaws are connected with piston rods of the clamping pressure cylinders; the middle lifting mechanism comprises a pressure cylinder and engaging lugs arranged at the two ends of the pressure cylinder, wherein, one end of one engaging lug is connected with the pressure cylinder and the other end of the engaging lug is connected with the upper clamping mechanism, and one end of the other engaging lug is connected with the pressure cylinder and the other end of the engaging lug is connected with the lower clamping mechanism; the lower clamping mechanism comprises a clamping body which is provided with a plurality of jaw bodies and clamping pressure cylinders, and the jaw bodies are connected with the piston rods of the clamping pressure cylinders; the two ends of the scale mechanism are respectively fixedly connected with the upper and lower clamping mechanisms; the leveling and clamping operations are finished at the same time, therefore, the work efficiency is improved and the cost is lowered.

Description

Internal and external clamping jacket leveling device technical field The utility model relates to offshore oil engineering construction equipment, in particular to an internal and external clamping jacket which is designed to combine a clamping pile structure and a leveling structure into one, and the equipment can realize the clamping and leveling actions of the jacket leveling device. Background technique Jacket levelers are almost always used when installing platforms offshore. At present, the internal and external clamping levelers of IHC in the Netherlands and the hook-type levelers of OilStates in the United States are generally used abroad. These two types of leveling The clamping function of the device is single and expensive. The Wenchang 13-1 / 2 jacket currently used in China is a shallow water jacket. Generally, a gripper is installed in the skirt pile casing, and the gripper is used to clamp one or several steel piles through the power station, and then The ...

AI Technical Summary

Problems solved by technology

Deeper water jackets use underwater skirt piles. Its leveling is different from shallow water jackets. Some special tools are required when installing deeper water jackets, such as jacket levelers, underwater pile clamps, and underwater cutting tools. Machines, internal and external pile hangers and conduit clamps, etc., need to use more equipment during construction, and the operation is complicated
