Abstract: A tong positioning system includes a positioning device configured to move a tong assembly. The positioning device includes a first actuator, a second actuator, and a control attachment attachable to the positioning device. The control attachment includes a shutoff valve fluidly coupled to a hydraulic supply, a control valve block, and a control device. The control valve block includes a hydraulic input fluidly coupled to the shutoff valve, a hydraulic output fluidly coupled to a hydraulic return, a first valve fluidly coupled to the first actuator, the first valve configured to actuate the first actuator, and a second valve fluidly coupled to the second actuator, the second valve configured to actuate the second actuator. The control device is configured to control the first valve and to control the second valve to actuate the first and second actuators to move the tong assembly.

Abstract: A coupling mechanism for coupling a first downhole tool to a second downhole tool includes a first portion, a second portion, and a locking device for locking the first portion to the second portion. The first portion includes a frame; a plug body movable relative to the frame; a guiding element coupled to the plug body; at least one of a hydraulic plug and an electric plug; and an actuator for moving the plug body relative to the frame. The second portion includes a receptacle body; a guide receptacle for receiving the guiding element; a respective receptacle for receiving at least one of the hydraulic plug; and the electric plug.
