Abstract
Disclosed is a guiding and injecting integrated mechanism for continuous conduit, belonging to underground exploration technical field. The mechanism comprises a pair of chain wheel and chain clamping assemblies used for clamping conduit and pulling conduit to go down or out of well. A conduit guiding channel for conduit to pass through is formed between the pair of chain wheel and chain clamping assemblies, and an inlet and an outlet of the conduit guiding channel are not situated in line. The conduit guiding channel is arc-shaped and each of the two chain wheel and chain clamping assemblies comprises a chain wheel set, chains, clamping blocks mounted on the chain, and a pushing plate for pressing the clamping blocks. Further, clamping surfaces of the clamping blocks have a certain curvature with respect to guiding direction.
