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.
