(54) УСТРОЙСТВО ДЛЯ РЕЛЮНТА МОРСКИХ НЕФТЕПРОМЫСЛОВЫХ ЭСТАКАД(54) DEVICE FOR RELYUNT OF SEA OIL AND FIELD EXTENSIONS

Изобретение относитс к области осмотра и ремонта гидротехнических сооружений типа эстакад морских нефтепромыслов .The invention relates to the field of inspection and repair of hydraulic structures such as offshore oil platforms.

Известно устройство дл осмотра пролетных строений мостов, содержащее по- . воротные приспособлени , противовесы и телескопические вышки tl.A device is known for inspecting bridge span structures, containing a. gate devices, counterweights and telescopic towers tl.

Такое устройство громоздко и при переводе из одного пролета в другой рабочую площадку необходимо разъедин ть.Such a device is cumbersome and, when being transferred from one span to another, the working platform must be disconnected.

Известно также устройство дл ремонта морских нефтепромысловых эста-, кад, включающее раму с5 направл ющими и монтированную на ней рабочую площадку с роликами f2.It is also known a device for repairing offshore oilfield racks, cad comprising a frame with 5 guides and a working platform mounted on it with rollers f2.

Недостатком известной конструкции вл етс то, что площадка расположена на тросах ниже пролетного строени эстакады и поэтому подвержена действию ветра и волн. Кроме того при переходе с одного пролета эстакады на другой площадку необходимо поднимать, переносить и снова спускать на тросах.A disadvantage of the known construction is that the platform is located on the cables below the span of the overpass and is therefore subject to wind and waves. In addition, when moving from one span of the overpass to another platform, it is necessary to lift, carry and lower again on cables.

Цель изобретени - обеспечение перемещени площадки по всей длине эстакады без ее подъема и спуска и повышение производительности труда.The purpose of the invention is to ensure the movement of the platform along the entire length of the overpass without its lifting and lowering and increasing labor productivity.

Это достигаетс тем, что устройство дл ремонта морских нефтепромысловых эстакад, включающее раму с направл ющими и монтированную на ней рабочую площадку с роликами, снабжено панелью с захватами и направл ющими, а рабоча площадка на стороне, обращенной к эстакаде имеет захваты, при этом ролики площадки установлены в направл ющих панели.This is achieved by the fact that the device for repairing offshore oilfield racks, which includes a frame with guides and a working platform mounted on it with rollers, is provided with a panel with grippers and guides, and the working platform has grippers on the side facing the ramp installed in panel guides.

Claims

The device for repairing offshore oilfield racks contains a site, a puffer 1 with flooring 2 and frames 3. The lower part of the frames has holders 4 with grippers 5 and 6. The platform is supported on tubular uprights 7 ® of the span 9. The axles 10 are fixed to the upper part of the frames with rollers 11 located in the guides 12 of the panel 13. The panel has grips 14, 15 and 16 consisting of cheeks 17 and 18 ending in a loop 19 on the axis 20 and having a cutout 21 and a round hole (not shown), for the passage of a finger 22 with a bolt 23. A wedge washer 24 is installed on the neck, and a wedge washer 25 and handle 26 on the finger. The device is used as follows. From the overpass, a panel 13 is installed on the pipe supports of the flying structure 9 and the grippers are clamped; 14-16. The grippers are clamped by inserting the valve 23 into the cutout 21 and turning the handle 26. Then, from the end of the panel 13, rolls II of the platform I are guided into the guides 12 and clamp grips 5 and 6. The ends of the guides are closed (not shown). Decking plates and the necessary tools and materials are placed on the flooring 2. The panels are installed on the lower horizontal tubular connections of the span 9 and are being repaired. At the end of the repair, the grippers 5, 6 are released and the platform 1 rolls along the guide 12 to the end of the panel. 13. Clamp the grippers 6, 5, give the grippers 14-16 and move the panel 13 along the rollers 11 to the new section. The end grips 14, 16 of the panel can be clamped and removed remotely by means of a cable drive. Repair of the supports is carried out with the help of gazebos lowered from site 1. The advantage of the device is uninterrupted repair of racks along the entire length, elimination of tripping and lifting operations, reducing labor intensity. Apparatus of the Invention A device for repairing offshore oilfield racks, including a frame with guides and a working platform mounted on it with rollers, which is characterized by the fact that, in order to move the platform along the entire length of the ramp, without raising and lowering it and increasing productivity, it is equipped with a panel with grippers and guides, and the working area has a gripper side facing the ramp, while the platform rollers are installed in the guides of the n-aneli.
