A conveyor apparatus (2), so-called injector head, to enable feeding of e.g. continuous tubing (7) or coiled tubing through the conveyor apparatus (2), to and from a wellhead and a well below and related to use of well tools. The apparatus has an apparatus frame (21), a pair of oppositely located, co-operatively movable, segmented continuous belts (28; 29) installed in the frame (21), each belt comprising a plurality of interconnected gripper shoe carriers (30) carried and movable by means of a pair of continuous belt drive chains (31; 32). A gripper shoe (52) to engage and convey the tubing (7) comprises: a gripper shoe base (53) having at a front thereof longitudinal first and second edge regions (53′; 53″), a first leg (54) and a second leg (55) extending at one end (54′; 55′) thereof from said first and second edge regions (53′; 53″), respectively, said legs being inclined towards each other, and first and second device (7; CED) gripper members (56; 57) being located at the other end (54″; 55″) of said first and second legs (54; 55) and extending in parallel in the direction of the belt (28; 29). |

1. A conveyor apparatus to enable feeding of continuous elongate device down through the conveyor apparatus, to enable insertion of tools through a wellhead and a well below or up through the conveyor apparatus by pulling action enabling retrieval of a tool from the wellhead and the well below, the conveyor apparatus comprising:
an apparatus frame, a pair of oppositely located, co-operatively movable, segmented continuous belts installed in the apparatus frame, each belt comprising a plurality of interconnected device gripper shoe carriers carried and movable via a pair of continuous belt drive chains running over respective pairs of chain drive sprockets, wherein each carrier has a front side and a rear side, wherein a device gripper shoe is located at the front side of each carrier, and wherein the device gripper shoe comprises:
a gripper shoe base having at a front thereof longitudinal first and second edge regions,a first leg and a second leg arranged on the base, said legs extending at one end thereof from said first and second edge regions, respectively, said legs being inclined towards each other, andfirst and second device (7; CED) gripper members being located at the other end of said first and second legs and extending in parallel in the direction of the belt, said gripper members being separated from the base by a space. |
