Abstract
The utility model provides a drilling tool lifting device and relates to a lifting device, in particular to a device used for lifting drilling tools. The drilling tool lifting device comprises a connecting part and a flying ring, a pair of lifting lugs is arranged on the upper portion of the connecting part, the lifting lugs are symmetrically arranged on the two sides of the connecting part, the tops of the two lifting lugs are fixedly connected through a connecting rod, and the flying ring is arranged in the connecting rod in a rotating mode. According to the drilling tool lifting device, the connecting part is connected with the drilling tools through threads, the drilling tools are hung up from the ground though steel wire ropes and placed in a designated position on a drill floor, in the lifting process, regardless of curling and deforming of the lifting ropes, the drilling tools are not affected due to the flying ring, the phenomenon of hard-stuck fracture is avoided, the drilling tool lifting device is simple in structure and strong in practicability.
Description
Technical field
The utility model relates to a kind of lifting appliance, particularly a kind of device for promoting drilling tool.
Background technology
Lifting screw protector is with kelly bar, the drilling tool that drilling rod and drill collar etc. are heavy, before going into the well, rise to the device of rig floor from ground, all be that lifting screw protector is screwed in the drilling tool internal thread at present, by boom hoisting drilling tool lifting to rig floor is finished, yet wire rope is through repeatedly using in the course of the work, often be twisted into twisted shape, so that drilling tool produces rotation when being lifted by crane, drilling tool is moving to from ground the rig floor process simultaneously, drags on ground first, then drags in the ramp of rig floor, be promoted to afterwards rig floor, drilling tool is in the rig floor moving process, and drop handle had not only born moment of torsion but also Bending load, and is very easily tired and rupture, in case fracture, not only damage lifting screw protector, drilling tool has directly damaged joint screw thread from dropping in the air, the more important thing is the personal safety of staff around having endangered.
Summary of the invention
The utility model is intended to propose to prevent that drilling tool from can effectively avoid the lifting appliance of drilling tool rotation in lifting process.
Connector and the suspension ring of comprising described in the utility model, connector top is provided with a pair of hanger, and hanger is arranged on the both sides of connector symmetrically, and the top of two hangers is fixedly connected with by connecting rod, and suspension ring rotate and are arranged in the connecting rod.
Drilling tool lifting device described in the utility model, connector and drilling tool thread are joined, by the wire rope drilling tool of slinging from ground, drilling tool is put into the rig floor assigned address, and in the lifting process, no matter how Texturized lifting rope is, drilling tool all can be all unaffected by suspension ring, avoided hard not Duan Lie phenomenon, the utility model is simple in structure, practicality is very strong.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Among the figure: the 1-suspension ring; The 2-hanger; The 3-connector.
The specific embodiment
Embodiment 1.
Drilling tool lifting device described in the utility model comprises connector 3 and suspension ring 1, and connector 3 tops are provided with a pair of hanger 2, and hanger 2 is arranged on the both sides of connector 3 symmetrically, and the top of two hangers 2 is fixedly connected with by connecting rod, and suspension ring 1 rotate and are arranged in the connecting rod.
Hang when getting drilling tool, drilling tool and connector 3 screw threads are joined, because suspension ring 1 are rotationally connected with hanger 2, therefore no matter how wire rope reverses, and all can not drive hanger 2 rotations, also can not drive the drilling tool rotation.
