Description

Special movable baffle device for catwalk of ocean module drilling machine

Technical Field

The utility model belongs to the technical field of oil drilling, concretely relates to dedicated adjustable fender device of ocean module rig catwalk.

Background

Ocean platform modular drilling rigs are increasingly used in the oil drilling industry. As a high-risk industry, the reliability and safety of field operation are the central importance of all production operations. The ocean module drilling machine catwalk is a walkway device for connecting a drilling platform surface and a drill rod storage yard. The pneumatic winch and the platform crane move pipes such as drill rods, sleeves and the like placed in a drill rod storage yard to a drilling platform surface through a catwalk of the marine module drilling machine; throwing the drill by a winch on the drilling platform surface, erecting the pipe and entering the rat hole; carrying out drill rod receiving operation; and then, storing the connected drill rods in a stand box near a top drive to supply the requirements of drilling operation at any time. In the process of moving and transporting a series of pipes, collision often occurs, so that damage to the drill rod, the catwalk, peripheral equipment and the like is caused, and a baffle needs to be arranged on the catwalk to block the movement inertia of the drill rod in the rod throwing process, so that the damage to the drill rod, the catwalk and the peripheral equipment is reduced.

Traditional ocean module rig catwalk has only set up fixed stop at the tip of keeping away from the rig floor. Because the baffle is fixed on the catwalk, the length and the size of the drill rod walkway cannot be changed. Because the length of the walkway is not matched with the drill rod, the drill rods with different lengths can shake in the catwalk of the ocean module drilling machine; therefore, the drill rod, the catwalk and peripheral equipment are impacted by the movement inertia of the drill rod, and damage is caused. In daily production, the damage of catwalk railings and peripheral deck equipment does also happen frequently. The catwalk component is the steel construction, appears damaging the back, and it is big to change the degree of difficulty, therefore catwalk life receives very big influence. And, under the unchangeable condition of original structure, in order to increase catwalk life-span, adopt thick steel sheet usually, caused catwalk weight to increase, be unfavorable for on-the-spot handling operation, aggravated the wearing and tearing of relevant node.

Therefore, there is a need to develop a removable, position adjustable flapper assembly on a catwalk of a marine modular drilling rig as a protective facility; the weight of the marine module drilling machine catwalk can be reduced when the marine module drilling machine catwalk is hoisted, the marine module drilling machine catwalk can adapt to the throwing rod operation of drill rods with different lengths, and the field drilling operation function is met. The movable baffle plate device has the advantages of simple structure, convenience in use and high repeated utilization rate, and can reduce the operation safety risk.

Detailed Description

The technical scheme of the utility model is described in detail below with reference to the attached drawings 1 ~ 8:

the utility model belongs to the technical field of oil drilling, concretely relates to dedicated adjustable fender device of ocean module rig catwalk. The catwalk of the marine module drilling rig comprises two parallel catwalk main beams 12; the catwalk deck 11 is fixedly welded on the inner sides of the upper planes of the two catwalk main beams 12; catwalk side walls 10 arranged at intervals are welded on the outer sides of the upper planes of the catwalk main beams 12 correspondingly; a plurality of movable railing installation pieces 8 are welded on the side wall 10 of the catwalk and the part of the swinging rod walkway; the movable railing 9 is arranged on the movable railing installation part 8. A plurality of interval intervals are formed between every two same-side catwalk side walls 10 which are arranged at intervals; at the interval position, baffle slot holes 13 are downwards formed in the catwalk main beams 12, and the baffle slot holes 13 in the catwalk main beams 12 on the two sides are processed and manufactured in pairs. The position of each pair of baffle slot holes 13 is the position where the movable baffle device can be vertically inserted. The movable baffle device is vertically inserted in the paired baffle slot holes 13 at different positions to form catwalks with different working lengths so as to adapt to the working conditions of drill rods with different lengths.

The special movable baffle plate device for the catwalk of the ocean module drilling machine comprises a rectangular anti-corrosion hard wood plate 5; which is vertically embedded in a hardwood fixed frame 6 to form a flapper main body. The hardwood fixing frame 6 is a U-shaped frame structure with an open upper part, is a welding part formed by 3 channel steel, specifically is formed by welding 1 vertical channel steel on two ends of 1 channel steel arranged on the bottom surface; the anti-corrosion hardwood board 5 is embedded and buckled in the hardwood fixing frame 6 to form a movable baffle main body together. Wherein, on 3 corresponding sides that anticorrosive hardwood board 5 and hardwood fixed frame 6 were embedded and detained, seted up with the structure that the channel steel was embedded and detained mutually makes among the stable hardwood fixed frame 6 that imbeds of anticorrosive hardwood board 5, and the biggest entity size that just encloses with hardwood fixed frame 6 of whole size is the same. Meanwhile, the embedded buckles of the anticorrosive hardwood plate 5 and the hardwood fixing frame 6 are in over-fit, and the anticorrosive hardwood plate 5 is a replaceable part; when the anticorrosive hardwood board 5 is damaged by impact, a new anticorrosive hardwood board 5 can be replaced into the hardwood fixing frame 6.

A reinforcing steel plate 3 is fixedly arranged on one side vertical surface of the movable baffle plate main body; the reinforced steel plate 3 is welded on one side vertical face of the hardwood fixing frame 6 and is attached to the anticorrosive hardwood plate 5; the reinforced steel plate 3 has the same area with the side vertical surface of the movable baffle plate main body. A plurality of reinforcing rib plates 4 arranged at intervals are welded at the lower part of the other side surface of the reinforcing steel plate 3; the bottom surface of each reinforcing rib plate 4 is flush with the bottom surface of the movable baffle main body.

Two side edges of the movable baffle plate main body are respectively fixedly welded with a supporting upright post 2; the supporting upright posts 2 are attached to the side edges of the movable baffle main body and extend downwards to form supporting legs; the positions and the sizes of the two corresponding supporting upright posts 2 correspond to baffle slotted holes 13 formed in the catwalk main beam 12; when the support column 2 is made of square steel or similar section bars, the upper end surface is welded with a sealing plate 7, and the sealing plate and the support column 2 are integrated. The sealing plate 7 is added, mainly for improving the strength of the support upright post 2. Finally, the upper end surface of the support upright post 2 is horizontal to the upper end surface of the movable baffle main body, and the lower part of the support upright post extends into the baffle slot hole 13 and does not interfere with the main girder 12 of the catwalk; at this time, the bottom surface of the main body of the movable baffle plate together with the bottom surface of the reinforcing rib plate 4 is just flatly placed on the catwalk deck 11.

And a lifting lug 1 with an ear hole is correspondingly welded at the upper part of the outer side of each supporting upright post 2. The pair of ear holes are used for hoisting the movable baffle device, so that the movable baffle device is separated from or installed into the catwalk of the ocean module drilling machine. The ear hole of the lifting lug 1 exceeds the upper end surface of the baffle main body, so that the lifting operation is facilitated.

The reinforcing steel plate 3 is positioned in the direction of the far end of the drill rod impact direction, the support legs of the two support columns 2 on the movable baffle plate device are clamped into the baffle plate slot holes 13, so that the movable baffle plate device is vertically arranged on the cross section of a catwalk deck 11 of a catwalk of an ocean module drilling machine to form a baffle plate and block drill rod impact.
