Wear-resistant hydraulic hoist for controlling stable output of gate

Abstract

The invention relates to a wear-resistant hydraulic hoist for controlling stable output of a gate. The wear-resistant hydraulic hoist comprises a fuel tank, a hydraulic pump, a hydraulic cylinder, a cleaning mechanism, a water supply mechanism, a heat conducting ring and a drain pipe, wherein the cleaning mechanism comprises a cleaning disc, a rotating ring, a plurality of rotating assemblies anda plurality of cleaning assemblies; the water supply mechanism comprises a water storage tank, a filter screen, a first water pump, a water suction pipe, a water injection pipe, a second water pump, awater conduit and a water guide tube. The wear-resistant hydraulic hoist for controlling stable output of the gate absorbs heat of the heat conducting ring conveniently by continuously inputting a water flow into the drain pipe through the water supply mechanism, so that the temperature of the hydraulic cylinder is reduced, hydraulic oil is prevented from being heated to expand to generate air bubbles, and stable output of the equipment is achieved. Furthermore, oil dirt on the inner wall of the hydraulic cylinder is absorbed through the cleaning mechanism and the condition that dust enters the hydraulic oil to lead to wear of equipment parts as the hydraulic cylinder is infected with dust is avoided, the equipment operates safely and reliably, and the practicality of the equipment is improved.

Description

technical field [0001] The invention relates to the field of hydraulic hoists, in particular to a hydraulic hoist for controlling gates with stable output and wear resistance. Background technique [0002] The hydraulic hoist is also called the gate hydraulic hoist. It refers to a hoist that uses the pressure of the liquid to transmit energy to control the opening or closing of the gate. It includes a hydraulic transmission system and an electro-hydraulic control system. It is composed of five parts: hydraulic pump, hydraulic valve, hydraulic cylinder, oil tank and accessories, electrical cabinet and operation table. [0003] During the operation of the hydraulic hoist, due to the reciprocating movement of the piston, the hydraulic oil in the hydraulic cylinder absorbs the kinetic energy of the piston, resulting in an increase in oil temperature. Since the hydraulic oil in the hydraulic cylinder is in a closed environment, the heating of the hydraulic oil will not only cause...

Problems solved by technology

[0003] During the operation of the hydraulic hoist, due to the reciprocating movement of the piston, the hydraulic oil in the hydraulic cylinder absorbs the kinetic energy of the piston, resulting in an increase in oil temperature. Since the hydraulic oil in the hydraulic cylinder is in a closed environment, the heating of the hydraulic oil will not only cause Expansion, but also produce air bubbles, affect the movement of the piston, resulting in unstable output of the hoist, not only that, when the hydraulic oil fills the inside of the hydraulic cylinder, the inner wall of the hydraulic cylinder is easy to absorb oil dirt, and the oil dirt is easy to adhere to various types Dust and impurities, when the piston moves to the oily position, it is easy to suck these dust and impurities into the hydraulic oil. With the increase of dust and impurities, these impurities are easy to wear the valves and other components inside the hoist, resulting in shortened service life of the equipment , thereby reducing the practicality of the existing hydraulic hoist
