Anti-blocking intelligent hydraulic hoist with quantitative control function

Abstract

The invention relates to an anti-blocking intelligent hydraulic hoist with a quantitative control function. The anti-blockage intelligent hydraulic hoist comprises an oil tank, an oil injection pipe,an oil pumping pipe, a hydraulic pump, a hydraulic cylinder, a piston, a supporting block and a controller; the side, away from the supporting block, of the oil injection pipe is provided with a cleaning mechanism, and the side, away from the supporting block, of the oil pumping pipe is provided with a cleaning mechanism; a quantitative mechanism is arranged in the oil tank, wherein the quantitative mechanism comprises a floating block, a connecting assembly, a sliding rod, a balancing block, a sealing assembly and four fixing rods; and each cleaning mechanism comprises a cleaning pipe, a driving chamber, a supporting frame and a sealing assembly, and each cleaning pipe is provided with a frame and a sponge block. According to the anti-blocking intelligent hydraulic hoist with the quantitative control function, dust impurities adsorbed on a filter screen can be adsorbed in time through the cleaning mechanisms, so that net holes of the filter screen are prevented from being blocked, andthe smooth circulation of hydraulic oil is guaranteed; and moreover, in the oil tank, the quantitative mechanism can automatically realize sealing of the oil injection pipe according to the oil level, the quantitative hydraulic oil is conveniently added into the oil tank, and the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of hydraulic hoist, in particular to an anti-clogging intelligent hydraulic hoist with quantitative control function. 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] In order to ensure the normal operation of the hydraulic hoist, the hydraulic oil in the oil tank needs to be replaced regularly after the hydraulic hoist has been in operation for a period of time. During the process of replacing and adding hydraulic oil, although the hoist is equipped with an oil filter to filter Dust and impurities in the hydraulic ...

Problems solved by technology

[0003] In order to ensure the normal operation of the hydraulic hoist, the hydraulic oil in the oil tank needs to be replaced regularly after the hydraulic hoist has been in operation for a period of time. During the process of replacing and adding hydraulic oil, although the hoist is equipped with an oil filter to filter Dust and impurities in the hydraulic oil, but as the dust on the surface of the oil filter increases, it is easy to cause poor flow of hydraulic oil and blockage, which will affect the operation of the equipment. The amount of oil added is not accurate, and it is easy to have too much or too little oil. When the amount of oil is too much, it will cause waste of resources. When the amount of oil is too small, the pressure will be low, and the hydraulic cylinder will be weak or unstable. , thereby reducing the practicability of the existing hydraulic hoist
