Ejector

Abstract

The invention discloses An ejector including a deck, the upper surface of the deck is provided with a rectangular sliding hole along the left-right direction, A U-shape sliding plate is fix on that lower surface of the deck corresponding to the rectangular sliding hole, the left and right ends of the U-shaped sliding plate are sealed, and a sliding groove is arranged between the U-shaped sliding plate and the deck, A slide groove and a traction block are slidably connected, A first fixed pulley is mounted on the right end of the lower surface of the deck through a mounting bracket, A hydrauliccylinder block is fixed on the lower surface of the U-shaped sliding plate, the inner wall of the hydraulic cylinder block is slidably connected with the piston side of the hydraulic cylinder, The high-pressure steam pushes the piston of the hydraulic cylinder to move rightward, and the piston of the hydraulic cylinder pushes the pulley to move rightward through the hydraulic cylinder lever, andthe pulley causes the moving speed of the traction block to be twice of the moving speed of the piston of the hydraulic cylinder, thus ensuring the sealing property between the piston of the hydrauliccylinder and the inner wall of the hydraulic cylinder block, and improving the ejection efficiency of the ejector.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a catapult. Background technique [0002] At present, for steam ejection, the length of the ejection cylinder should be the same as the required ejection distance, and the cylinder body is assembled and processed in sections. When the piston moves forward, the opening of the cylinder body behind the ejection should be sealed with a sealing tape to ensure the steam pressure; The faster the moving speed of the piston, the worse the sealing between the piston and the cylinder will affect the ejection effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a catapult. The high-pressure steam pushes the piston of the hydraulic cylinder to move to the right, and the piston of the hydraulic cylinder pushes the movable pulley to move to the right through the lever of the hydraulic cyli...
