Problems solved by technology

[0005] Fault maintenance: Manual inspection and maintenance are performed only when the equipment is damaged or cannot work normally. This method takes a long time for equipment downtime, requires high on-site operators, and high maintenance costs;
[0006] Maintenance control: The daily maintenance and operation control of the equipment is carried out manually by referring to the manual, the steps are cumbersome, the requirements for the users are high, and mistakes are prone to occur
This method is easy to cause waste of maintenance, and even cause hidden dangers in the maintenance process.
Moreover, equipment maintenance adopts a fixed cycle method, which cannot be completely consistent with the actual use status, and the equipment may break down between two maintenances, causing huge losses

Embodiment 1

[0037] The present invention is as follows to the discovery processing step of oil pollution:

[0038] During operation, the oil resistance and oil transparency sensors feed back the data of oil conductivity and oil transmittance in real time. When the conductivity exceeds the set threshold and the light transmittance is lower than the set threshold, the central control system will give the oil Pollution alarm and reminder to check and replace the oil, and send the warning information to the upper monitoring machine and portable equipment, and send a short message to the set mobile phone number at the same time.

[0039] When only the conductivity exceeds the set threshold, the central control computer system will analyze the historical data log. If the recent conductivity data shows a continuous upward trend, the central control computer system will give an oil pollution alarm and prompt to check and replace the oil, and will warn The information is sent to the host monitorin...

Embodiment 2

[0042] The present invention controls the automatic deviation correction of the gate during installation, commissioning and maintenance as follows:

[0043] Select automatic gate deviation correction on the on-site portable control device, the system checks the cylinder stroke position data, and controls all cylinders to move synchronously to the half-extended state; the system checks the gate level sensor data, judges the deviation on both sides according to the sensor data, and slowly lifts the low side cylinder to The sensor gives the level data; it gives a prompt that the gate deviation is in place, wait for confirmation, and after confirmation, set the stroke positions of the cylinders on both sides to bind synchronously.

Abstract

The invention relates to an intelligent hydraulic hoist which comprises a hydraulic cylinder, a hydraulic station, a control cabinet, a centralized control machine, an upper monitor and mobile equipment. The intelligent hydraulic hoist achieves operation condition real-time remote monitoring, operation abnormal condition and fault remote diagnosis and operation instruction automatic control. Monitoring data and prompting and alarming information are transmitted to the upper monitor through the Internet or a special data line, and the monitoring data and the prompting and alarming information are transmitted to the upper monitor through a wireless data line or mobile short messages. The intelligent hydraulic hoist is wholly intelligent and digitized, automatic control over operation is guaranteed, full time domain monitoring of working conditions is achieved, intelligent remote diagnosis of faults and abnormal operation is achieved, and an intelligent guarantee is provided for normal operation.

Description

technical field [0001] The invention relates to the field of design and manufacture of a hydraulic hoist, which is used in water conservancy and hydropower projects, ship locks, water locks, ship lifts and other fields using hydraulic hoist systems. Background technique [0002] The hydraulic hoist is generally composed of a hydraulic station, a hydraulic cylinder, a hydraulic circuit and related electrical control systems. It is often used for the opening and closing operation of the gate, and its operation safety and reliability are of great significance. The mechanism of the hydraulic hoist is complex, involving multiple technical fields such as hydraulic pressure, machinery, electrical appliances, and structure, and its specificity is very strong. Its daily maintenance and fault inspection and maintenance have very high requirements for technicians, and it is often located in remote areas. Make it difficult for service technicians to respond quickly on site. [0003] At...
