1. The device comprises a box body structure, 2 parts of a lifting device, 3 parts of an inclined supporting rod, 41 parts of bolts, 42 parts of eye plates, 5 parts of fixing piles, 6 parts of lifting lugs and 7 parts of an auxiliary vertical ladder.

Detailed Description

As shown in FIGS. 1-4, a novel multipurpose CTP-BOX structure comprises a lower BOX body structure 1, wherein the length, X, width, X and height are 14450mmX5970mmX6045 mm. Can meet the operation requirements of various height positions. The upper split lifting device 2 is arranged in a pipe frame type structure on the width of both sides of the box body structure 1. The frame on the top surface of the box body structure 1 is welded with the frame on the lower section of the lifting device 2; the structure length of the lower section of the separated lifting device 2 is 3150mm, and the lower section of the separated lifting device is welded and fixed with the upper part of the box body frame. The length of the upper section of the lifting device 2 is 3250mm, and the lifting device 2 is connected with the lower section of the lifting device 2 in an eye plate 42-bolt 41 mode.

The lower section and the upper section of the lifting device 2 are connected in a bolt manner.

Box structure 1 is the open cuboid structure in upper portion, adopts square tube frame construction, and the wall seals for the buckled plate around four, and the bottom is equipped with the CTU base platform that can supply BOP lateral sliding in the frame, as the fixed and horizontal carrier that slides of BOP. The CTU base platform transversely moves through hydraulic pushing.

The lifting device 2 is in a square tube frame connection combination form, and corrugated plates are also adopted in the frame.

The length of the diagonal support bar 3 is 6100mm, one end of the diagonal support bar 3 is fixed with the eye plate 42 arranged on the square tube frame of the lifting device 2 through the bolt 41, and the other end is fixed with the eye plate 42 arranged on the lifting device 2 through the bolt 41. Thereby forming a pair of closed, relatively stable mechanisms. The bolt-eye plate type connection is used, so that later use, disassembly and maintenance are facilitated; after the work is finished, the upper section of the lifting device 2 can be placed in a groove-shaped area formed by the lower section of the lifting device 2 and the fixed pile 5 after being disassembled; the design of the assembly lifting lug 6 is convenient for loading, unloading, transferring and transporting of each part.

A groove shape is formed between the lower section of the lifting device 2 and the fixed pile 5; the lower section of the lifting device 2, the fixing pile 5 and the box body structure 1 are fixed through wood wedges or binding bands, and the gap shaking is prevented. When the operation is finished, the upper section of the lifting device 2 can be stored in the groove shape after being disassembled.

Establish fixed lug 6 on 2 top member bars of hoisting device, utilize original BOP hanging beam, use when making things convenient for the device to disassemble hoist and mount.

Auxiliary vertical ladders 7 are arranged at two ends of the box body structure 1. When the whole device is assembled, the detachable vertical ladder can be installed firstly, and then all parts are assembled and fixed through bolts. When disassembling, the detachable straight ladder can be used for disassembling all the parts. In the CTP use process, the detachable vertical ladder can be used as an access CTP channel.

When the BOP operation height only needs the height of the box body 1, a fixing bolt is inserted into a bolt hole on the box body structure 1 and is fixed at a moon pool; when the height needs to be increased by 2700mm, the bolt is inserted into the bolt hole at the lower section of the lifting device 2 and fixed at the moon pool; when the height needs to be increased by 6000mm, at this time, as long as the bolt is inserted into the bolt hole at the upper section of the lifting device 2 and fixed at the moon pool, the inclined support rod 3 is assembled to be connected to the eye plate at the top of the lifting device 2 and the fixed eye plate on the box body 1, and the lifting device 2 is integrally reinforced. The hoisting operation of each part and the installation of the bolt can be completed by assembling the lifting lug 6 and the detachable vertical ladder 7.

As shown in fig. 5, after the operation is completed, the assembling lifting lug 6 can be used to assist the vertical ladder 7 in the disassembling operation of each part. The upper section of the lifting device 2 can be stored in the groove-shaped area formed by the lower section of the lifting device 2 and the fixing pile 5 after being disassembled.

The novel CTP-BOX device extends the use function of the original CTP-BOX device, and is convenient to disassemble, recover and maintain.
