Description

Rotary lifting wire

Technical Field

The utility model relates to an oil reservoir field, concretely relates to silk is carried in rotation.

Background

The drilling industry is a high-risk industry, particularly in field operation, and multiple species are required to cooperate, so that the safety work is more important. One of the more used tools for drilling teams is the drilling tool hook. Conventionally, when a drill pipe and a drill collar are hoisted to a drill floor from a drilling site, a steel wire rope, a palm rope and the like are generally adopted, and a safety slip is still used when the drill collar is hoisted, so that the safety slip is consistently manufactured for decades and never changes. In the prior art, the wire lifting hanging drill rod is directly used, tools such as pipe tongs, hammers and crowbars are required to be buckled in the process of buckling, a plurality of people cooperate with each other to complete the confining work, a large amount of manpower and material resources are required to be invested, and the labor force of staff is increased. In the lifting process, the swinging of the facility collides with the well platform equipment or hurts people, so that serious accidents such as crushing, bruising and the like are easily caused.

There is therefore a need to develop a rotary lifting wire that makes it safer to lift or lower a drill tool.

The information disclosed in this background section of the invention is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rotatory silk of carrying, this rotation is carried the silk and is made to promote or transfer the drilling tool more safety.

In order to achieve the above object, according to the present invention, there is provided a rotary lifting wire, comprising a joint, a connecting shaft and a shackle;

the shackle comprises a connecting pin and a pull ring, wherein the connecting pin penetrates through the pull ring and one end of the connecting shaft to fix the shackle on the connecting shaft;

the other end of the connecting shaft is provided with a bulge, the joint is sleeved on the bulge, and the joint can rotate relative to the connecting shaft.

Preferably, one end of the joint is a drill rod joint thread, and the middle of the joint is provided with a through hole.

Preferably, the joint, the connecting shaft and the shackle are made of a cemented carbide material.

Preferably, the end face of the joint on the side far away from the connecting shaft is a plane.

Preferably, still include lubricating oil teaching mouth, lubricating oil teaching mouth is seted up on the joint, communicate in the joint with the gap between the connecting axle.

Preferably, a sealing plug is arranged at one end, far away from the connecting shaft, of the lubricating oil teaching port.

Preferably, the protrusion is disc-shaped, and the protrusion and the connecting shaft are integrally formed.

Has the advantages that: through establishing the adapter sleeve on the connecting axle, when articulate in the drilling tool, promote and transfer the drilling tool when, when the drilling tool is obstructed, the drilling tool can take place to rotate, alleviates the impact force and avoids the drilling tool swing, makes the drilling tool promote and transfer more safety.

Drawings

Fig. 1 is a schematic structural view of an embodiment of the rotary silk lifting device of the present invention.

Description of reference numerals:

1. a joint; 2. a connecting shaft; 3. shackle dismounting; 4. a connecting pin; 5. a pull ring; 6. and (4) protruding.

Detailed Description

The technical scheme of the utility model is described in detail with the accompanying drawings.

The utility model provides a silk is carried in rotation, this silk is carried in rotation includes: a joint, a connecting shaft and a shackle;

Specifically, through establishing the adapter sleeve on the connecting axle, when articulate in the drilling tool, promote and transfer the drilling tool when, when the drilling tool is obstructed, the drilling tool can take place to rotate, alleviates the impact force and avoids the drilling tool swing, makes the drilling tool promote and transfer safer.

Specifically, the shackle is detachably connected to the connecting shaft through the connecting pin, so that the steel wire rope coil is convenient to detach and install.

Furthermore, one end of the joint is provided with drill rod joint threads, and the middle of the joint is provided with a through hole.

Further, the joint, the connecting shaft and the shackle are made of hard alloy materials. Specifically, the hard alloy material has higher mechanical strength and longer service life.

Furthermore, the end face of one side of the joint, which is far away from the connecting shaft, is a plane.

Further, still include lubricating oil and instruct mouthful, lubricating oil instructs mouthful to set up and establishes in on the joint, communicate in the joint with gap between the connecting axle.

Furthermore, a sealing plug is arranged at one end, far away from the connecting shaft, of the lubricating oil teaching port.

Specifically, through the setting of lubricating oil teaching mouth, can think to connect and add lubricating oil in the gap between the connecting axle, be convenient for connect for the connecting axle rotates, make to connect rotational sensitivity higher, use safer.
