Abstract
Winch is compensated the utility model discloses a kind of oil-well rig twin-roll, it includes actuating unit, roller, is interference fitted the roller axle assembly being connected by key with roller, the two ends of roller axle assembly are connected by drum gear coupling with decelerator, decelerator is connected by shaft coupling with actuating unit, the two ends of roller are provided with wheel hub and hydraulic disc brake mechanism, baffle plate is welded with the middle part of the roller, roller is divided into twin-roll by baffle plate, and the both sides of twin-roll are equipped with the steel wire rope being connected with hoisting system of rig.The utility model is compared with traditional winch, and roller volume diminishes, compact conformation, twin-roll synchronous axial system, coordinates rig double quick rope lifting system to carry out drillng operation and improves operating efficiency, saves drilling cost.
Description
Technical field
The utility model is related to offshore petroleum rig equipment technical field, and specifically a kind of oil-well rig twin-roll is mended
Repay winch, it is adaptable to oil-well rig double quick rope lifting system.
Background technology
The side of the typical well winch of conventional petroleum hoisting system of rig operation is coordinated to lift end, other side for fast line
For dead line fixing end, winch drum volume is larger, it is necessary to which powerful actuating unit provides power for winch, and is using
Raising efficiency is relatively low in journey.Conventional marine oil-well rig is equipped with crown-block heave compensator in lifting system or tourist bus heave is mended
Device is repaid, its is complicated, manufacture and maintenance are difficult.
Utility model content
The purpose of this utility model is to provide a kind of oil-well rig twin-roll compensation winch, and heave compensation function is combined in into strand
Car, big to solve traditional winch drum volume, operating efficiency is not high, and compensation device takes the problem of platform space is big.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of oil-well rig twin-roll compensates winch, and it includes roller, and roller is connected to rolling by interference fit and key
Cylinder axle assembly, the two ends of roller axle assembly are connected by drum gear coupling with decelerator, and decelerator is by shaft coupling with moving
Force mechanisms are connected, and the two ends of roller, which are provided with the middle part of wheel hub and hydraulic disc brake mechanism, the roller, is welded with baffle plate,
Roller is divided into twin-roll by baffle plate, and the both sides of twin-roll are equipped with the steel wire rope being connected with hoisting system of rig, roller two
Steel wire cord-fixing structure is respectively equipped with the web at end.
It is preferred that, every group of actuating unit is according to two to four motors of power configuration.
Drum gear coupling is connected with roller axle assembly by bearing.
Twin-roll of the present utility model being capable of synchronization action, cooperation rig double quick rope lifting system progress drillng operation.
The utility model is compared with traditional winch, and roller volume diminishes, compact conformation, and twin-roll synchronous axial system is carried
High operating efficiency, saves drilling cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, actuating unit, 2, shaft coupling, 3, decelerator, 4, drum gear coupling, 5, bearing, 6, steel wire rope, 7, rolling
Cylinder axle assembly, 8, roller, 9, baffle plate, 10, hydraulic disc brake mechanism.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of oil-well rig twin-roll compensates winch, and it includes roller 8, and roller 8 is connected to by interference fit and key
Roller axle assembly 7, the two ends of roller axle assembly 7 are connected by drum gear coupling 4 with decelerator 3, and decelerator 3 passes through shaft coupling
Device 2 is connected with the actuating unit 1 being made up of four motors, and the two ends of roller 8 are provided with wheel hub and hydraulic disc brake mechanism
10, the middle part of roller 8 is welded with baffle plate 9, and roller 8 is divided into twin-roll by baffle plate 9, and the both sides of twin-roll are equipped with to be carried with rig
Steel wire cord-fixing structure is respectively equipped with the steel wire rope 6 that the system of liter is connected, the web at the two ends of roller 8.
Power is acted on winch axle assembly 7 by two ends actuating unit 1 simultaneously by shaft coupling 2, decelerator 3, so as to drive
The synchronous axial system of twin-roll 8, the steel wire rope of winding on the cylinder 8 synchronously starts to rotate, and is lifted by rig double quick rope lifting system
Respective hook is carried, and realizes drillng operation.
