Abstract
The utility model provides a kind of well workover single armed bearing hoisting ring mechanism, comprise loading arm, wherein, the two ends of described loading arm are respectively arranged with 2 suspension ring, described 2 suspension ring separate at an angle, are provided with olive-shaped connector between described suspension ring and loading arm, and the end of described connector is provided with stepped chuck, described loading arm is distributed with multiple groove, the connector of described loading arm lower end is also provided with two curved channels.The advantage that the utility model has and good effect are: increase suspension ring and to sling the quantity of hook, make lifting operation ability double, olive-shaped connector can increase substantially the lifting capacity of lifting ring mechanism, the moving direction of exterior mechanical arm suspension ring easy to control, be specially adapted to rig floor lifting drilling tool and well workover time load bearing applications.
Description
Technical field
The utility model belongs to oil drilling equipment technical field, especially relates to a kind of well workover single armed bearing hoisting ring mechanism.
Background technology
In oilfield, workover treatment, when connecting hook block and elevator when lower tubular column, single-arm hoisting ring is a kind of for connecting the special tool with load-bearing, the hook load-bearing that single-arm hoisting ring mainly connects is larger, but the end small volume of hook, a single-arm hoisting ring hook of only slinging often makes the ability to work of plant equipment not give full play to, therefore, prior art existing defects, requires further improvement and perfect.
Summary of the invention
Problem to be solved in the utility model is the hook quantity of slinging increasing common suspension ring, is particularly suitable for oilrig for lifting various drill bit and drilling tool.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of well workover single armed bearing hoisting ring mechanism, comprise loading arm, wherein, the two ends of described loading arm are respectively arranged with 2 suspension ring, and described 2 suspension ring separate at an angle, olive-shaped connector is provided with between described suspension ring and loading arm, the end of described connector is provided with stepped chuck, and described loading arm is distributed with multiple groove, the connector of described loading arm lower end is also provided with two curved channels.
Further, the angle of described 2 suspension ring is 10-20 degree.
Further, described groove helically fills and is uniformly distributed.
The advantage that the utility model has and good effect are: increase suspension ring and to sling the quantity of hook, make lifting operation ability double, olive-shaped connector can increase substantially the lifting capacity of lifting ring mechanism, the moving direction of exterior mechanical arm suspension ring easy to control, be specially adapted to rig floor lifting drilling tool and well workover time load bearing applications.
