Abstract
A large scale hydraulic cylinder assembly, disassembly and maintenance system to hoist a hydraulic cylinder in the air, secure one end of the hydraulic cylinder to a tooling piece secured to a movable hydraulically operated torque head and secure a second end of the hydraulic cylinder to a tooling piece secured to a movable tail stock, and thread or unthread nuts to or from both ends of the hydraulic cylinder under high speed low torque and low speed high torque.
Claims8
A hydraulic cylinder assembly, disassembly and maintenance system, comprising:
- an elongated cylindrical pipe having first and second ends and including:
- a pair of guide rails extending in parallel along a top portion thereof, and
- at least one ball screw extending between the pair of guide rails, the at least one ball screw including a sprocket attached to a first end thereof and disposed at the first end of the cylindrical pipe;
- a torque head assembly including:
- a pair of rail guides fixed to a bottom thereof to slide along a corresponding one of the pair of guide rails;
- a ball screw push bar disposed between the pair of rail guides, the ball screw push bar including at least one ball screw nut configured to threadedly receive the at least one corresponding ball screw therethrough to move the torque head assembly along the guide rails when the at least one ball screw is rotated;
- a rotating reel having notches around a circumferential surface thereof and a torque head tooling connector plate connected thereto which rotates together with the rotating reel, the torque head tooling connector plate being configured to receive any one of a first set of interchangeable tooling pieces thereon that each securely engage with a first end of a hydraulic cylinder to rotate the first end of the hydraulic cylinder;
- a rotation motor configured to rotate the rotating reel at a high speed and low torque;
- and
- a high torque cylinder configured to extend and retract to engage with the notches of the rotating reel to rotate the rotating reel at a lower speed and higher torque than the rotation motor;
- and
- a tail stock assembly including:
- a tail stock tooling connector plate having a pair of slide plates to slide along a corresponding one of the guide rails, the tail stock assembly configured to receive any one of a second set of interchangeable tooling pieces thereon to fixedly engage with a second end of the hydraulic cylinder.
