Abstract
The utility model discloses a tool for underwater flange connection. The tool is provided with two flange clamping components in same structure and a guide seat. Each flange clamping component mainly comprises a panel holder and a panel arranged on the panel holder; the panel holder is provided with a clamping groove, and the panel is provided with a hydraulic draw bar clamping groove. The guide seat is provided with a flange guide groove, and two flanges to be connected are arranged in the flange guide groove of the guide seat. Positioning pins for being inserted into flange mounting holes are arranged in the side wall, facing one flange surface, in the clamping groove of the panel holder. By the aid of the tool of the structure, flange connection is facilitated greatly, and convenience in operation is achieved. As the two flanges to be connected are arranged in the flange guide groove of the guide seat, the two flange clamping components in the same structure are assembled on the two flanges, and the two flanges are pulled to be closer by the hydraulic draw bar and then connected, underwater flange connection efficiency is improved and underwater flange connection load of divers is reduced.
Description
Technical field
The utility model relates to the special tooling of a kind of offshore oil or natural gas extraction equipment, specifically a kind of facility of connection under water of submerged pipeline flange.
Background technology
Oil or the natural gas of drilling and producing platform exploitation are transported in submerged pipeline by the platform standpipe, then are transported to the FPSO(floating production storage unit) or land terminal.Between each of platform section standpipe, between standpipe and seabed expansion bends and between expansion bends and the flat pipe in seabed, all by flange, be connected.The shallow water submarine pipeline of the depth of water 300 m left and right is manipulate directly or using the underwater sealing cabin as working space enforcement connection by the diver mostly.
When the diver carries out the flange connection under water, be to utilize manpower or adjust the flange position by chain block, the end face of flange that furthers, the center line of manual synchronizing abutted flange, then complete the flange connection after tightening some bolts.The method time and effort consuming, operating efficiency is very low.Due to the underwater operation personnel and the time diver underwater operation limited time, in the urgent need to a kind of method of attachment under water efficiently.
Through patent retrieval, do not find identical with the utility model or close or similarly connect facility under water.
Summary of the invention
In order to improve flange joint efficiency under water, alleviate diver's flange and connect working load under water, the invention provides a kind of facility that connect for underwater flange, can realize that by these facility flange efficiently connects under water.
The technical solution of the utility model is as follows: a kind of facility that connect for underwater flange, it is to clamp part and a guide holder forms by two identical flanges of structure, described flange clamps part and mainly consists of the panel bed with draw-in groove and the panel that is located on panel bed, described panel is provided with the hydraulic pressure draw-bar draw-in groove, described guide holder is provided with the flange gathering sill, and the flange of two needs connections is located in the flange gathering sill of guide holder.
In described panel bed draw-in groove with flange face over against sidewall be provided with to insert the alignment pin of flange mounting hole.
Described alignment pin is provided with two.
An on described guide holder and end that is positioned at gathering sill is provided with baffle plate, and the surface of described baffle plate is provided with to insert the pin of flange mounting hole.
Described pin is provided with two.
Described panel bed is provided with the panel stiffener vertical with panel.
Described panel stiffener is provided with two, and two panel stiffeners are parallel to each other.
The beneficial effects of the utility model: owing to adopting above-mentioned version, greatly facilitate the connection of flange, and easy and simple to handle, the flange that two needs are connected is located in the flange gathering sill of guide holder, again two identical flanges of structure are clamped to part and be installed on two flanges, utilize hydraulic pressure draw-bar that two flanges are furthered, and connected, improved flange joint efficiency under water, alleviated diver's flange and connected working load under water.
