US 2012/0222855 A1 · Multi-Faceted Gripper Block for Coiled Tubing Injector

Abstract

An improved multi-faceted gripper block to improve the interchangeability of gripper blocks when the need arises to change the size of the diameter material (e.g. tubing, cable, plastic, wire, hoses, or pipe) or to improve the interchangeability of gripper blocks when the need arises to change one or more gripper blocks due to unservicability. The gripper block assembly comprises a carrier body being connectable to a gripper chain in an injector apparatus, a removable and rotatable gripper block insert having one or more longitudinal sides created with one of many types of known gripping channels or surfaces for engaging tubing or other or other such elongated items. The gripper block insert can be secured into the carrier and can be removed and then replaced or rotated without removing a serviceable carrier.

Dependent claims

A multi-faceted gripper block for use in connection with a device having at least one gripper chain and at least one carrier body for moving a rod, pipe, coiled tubing, cable, or like elongated object, the multi-faceted gripper block comprising:

a gripper block insert having a longitudinal axis and at least two longitudinal sides oriented to fit into the carrier body;
a laterally oriented means of attaching the gripper block insert to the carrier body;
wherein the gripper block insert comprises at least two longitudinal sides that contain a gripping region for engaging the elongated object and transmitting injection and extraction forces upon the elongated object, wherein only one longitudinal side containing a gripping region is capable of contact with the elongated object at a time;
wherein the gripper block insert can be unattached from the carrier body and reattached to the carrier body and have a different longitudinal side containing a gripping region in contact with the elongated object.
