Abstract
A coiled tubing injector unit insert assembly includes a gripping insert configured to be coupled to a carrier block, the insert comprising a tongue with a first cutout configured to engage a shaft extending within a carrier block pocket, the shaft having a first diameter portion and a second larger diameter portion and a junction between the two shaft diameters that is located within the carrier block pocket to couple the gripping insert to the carrier block.
Claims18
A coiled tubing injector unit insert assembly comprising:
- a carrier block having a carrier block pocket;
- a shaft extending through the carrier block pocket, the shaft having a first diameter portion and a second larger diameter portion, and a junction between the two shaft diameters that is located within the carrier block pocket;
- and
- a gripping insert having a tongue, the tongue comprising at least a first cutout configured to engage the shaft extending through the carrier block pocket and couple the gripping insert to the carrier block, and a peripheral cutout having a width less than the diameter of the first cutout.
A coiled tubing conveying apparatus comprising:
- a pair of continuous parallel drive chains revolving in a common plane, said pair of continuous drive chains having opposed, elongated parallel runs spaced apart to form a path for engaging tubing passing there through;
- and
- a plurality of gripping insert assemblies carried on each of said pair of continuous drive chains, each comprising a gripping insert configured to be coupled to a carrier block, the insert comprising:
- a tongue with a first cutout configured to engage a shaft extending within a carrier block pocket,
- wherein the shaft is configured having a first diameter portion and a second larger diameter portion substantially the same size as the first cutout, and a junction between the two shaft diameters that is located within the carrier block pocket to couple the gripping insert to the carrier block.
A method of assembling a coiled tubing injector unit insert assembly comprising:
- providing a gripping insert configured to be coupled to a carrier block, the insert comprising a tongue with a first cutout configured to engage a shaft extending within a carrier block pocket, the shaft having a first diameter portion and a second larger diameter portion and a junction between the two shaft diameters that is located within the carrier block pocket to couple the gripping insert to the carrier block;
- inserting the gripping insert tongue into the carrier block pocket until the first cutout is substantially concentrically aligned with the larger shaft diameter portion;
- sliding the gripping insert in a first direction and causing the first cutout in the tongue to engage the larger shaft diameter portion, thereby coupling the gripping insert to the carrier block;
- and
- using a locking mechanism when the first cutout has engaged the larger shaft diameter portion, thereby restricting the gripping insert from sliding in a direction opposite the first direction.
