pneumatic slips

pneumatic slips are installed in the 275 and 375 rotary tables. The balance beam is connected to the four-page slip body through the connecting rod, and the cylinder and the guide rod are fixedly connected to the balance beam. When tripping the drill pipe, the slip body descends along the conical surface of the main body, pushing the drill pipe to close to the center and clamping the drill pipe tightly. When lifting the drill pipe, the slip body shall loosen the drill pipe upward along the conical surface of the main body to make the drill pipe and coupling pass through the space.
