Abstract

The invention relates to the technical field of hydraulic hoists, and discloses a hydraulic hoist for water conservancy. The hydraulic hoist comprises a hydraulic cylinder, a piston body is movably sleeved with the hydraulic cylinder, an oil inlet and outlet is fixedly connected to the top end of the hydraulic cylinder, bowl-shaped scraping rings are fixedly connected to two sides of the piston body correspondingly, and a fixed base is fixedly connected to one side of each bowl-shaped scraping ring. A fixed block is fixedly connected to one side of each fixed base, springs are evenly distributed on the outer portion of the fixed bases in the circumferential direction, and the other ends of the springs are fixedly connected with the interiors of the bowl-shaped scraping rings. The piston body drives the bowl-shaped scraping rings to scrape impurities attached to the inner wall of the hydraulic cylinder, the fixed blocks collect the impurities attached to the inner wall while removing the impurities on the inner wall through the magnetic action between elastic air bags and movable heads, due to the position arrangement of the bowl-shaped scraping rings, the condition that the impurities enters a piston and abrades the piston part is avoided, the service life of the piston part is prolonged, and the problem of inner leakage caused by abrasion is avoided.

Description

technical field [0001] The invention relates to the technical field of hydraulic hoists, in particular to a water utilization hydraulic hoist. Background technique [0002] The hydraulic hoist is an assembly composed of a hydraulic cylinder as the main body, an oil pump, a coarse motor, an oil tank, an oil filter, and a hydraulic control valve. To make the piston move in the hydraulic cylinder to drive the gate to open or close, and the hydraulic oil in the hydraulic cylinder needs to be replaced regularly, and the hydraulic cylinder and other components also need regular cleaning and maintenance. [0003] In the use of hydraulic cylinders, in order to ensure the passage speed of hydraulic oil, the filter will filter relatively large impurities. Impurities generated during work, colloids, asphaltene, carbon residues, etc. produced by the oil due to oxidation and deterioration, will flow with the hydraulic oil, and thus partially adhere to the inner wall of the hydraulic cyl...
