摘要： 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.

摘要： Disclosed is a continuous conduit apparatus based on guiding and injecting integrated mechanism, which comprises a straightening apparatus and a pair of sprocket and chain clamping assemblies. The pair of sprocket and chain clamping assemblies are configured to clamp the conduit and pull the conduit to go downwards a well or upwards a lifting direction. Between the pair of sprocket and chain clamping assemblies, a conduit guide channel applied for the conduit to passing through is formed. An inlet and an outlet of the conduit guide channel are not situated in a straight line, and the straightening apparatus are configured to straighten the conduit. Each of the two sprocket and chain clamping assemblies comprises a sprocket set, a chain, a plurality of clamping blocks mounted on the chain, and a pushing plate configured to press the clamping blocks.

摘要： Disclosed is a continuous conduit operation apparatus, which comprises a folding frame and a guiding and injecting integrated mechanism configured to pull the conduit to go downwards a well or upwards a lifting direction. The folding frame comprises a base, a mounting frame connected to the base in a movable connection, and a telescopic mechanism configured to rotate the mounting frame in a vertical plane around a position of the movable connection. One end of the telescopic mechanism is movably connected to the base, another end of the telescopic mechanism is movably connected to the mounting frame. The guiding and injecting integrated mechanism is arranged on the mounting frame. The present disclosure integrates the guiding function and the injection function to reduce the height of the apparatus and is suitable for operation environment with limited space and height.
