Emergency operation device of battery driven mobile type hydraulic opening and closing machine and working method thereof

Abstract

The invention relates to an emergency operation device of a battery driven mobile type hydraulic opening and closing machine and a working method thereof. The device comprises a power supply driving assembly and a hydraulic control system. The power supply driving assembly comprises a battery pack and a direct current motor. A first quick connecting hose and a second quick connecting hose connected to rod cavities of two hydraulic cylinders of the hydraulic opening and closing machine separately, a fifth quick connecting hose and a sixth quick connecting hose connected to a hydraulic oil tankof the hydraulic opening and closing machine and a third quick connecting hose connected to control pipelines of the hydraulic cylinders of the hydraulic opening and closing machine are arranged on the hydraulic control system, the first and second quick connecting hoses are separately connected to oil dividing ports at two ends of a dividing and collecting valve through pipelines, a pressure sensor and a branch pipeline are arranged on an oil dividing port pipeline of the dividing and collecting valve, the outer end of the branch pipeline is connected to an oil unloading oil tank, and an electromagnetic switch valve is arranged on the branch pipeline. In an emergency operation, the emergency operation device can synchronously control the two hydraulic cylinders of the hydraulic opening and closing machine with high precision so as to start a gate stably and reliably.

Description

technical field [0001] The invention relates to the field of hydraulic hoist, in particular to a battery-driven mobile hydraulic hoist emergency operating device and a working method thereof. Background technique [0002] The hydraulic hoist is used to operate the opening and closing of large gates in water conservancy and hydropower projects, and has high reliability requirements. There is a time requirement for the opening and closing of the gate. If the gate cannot be opened or closed within a certain period of time, different degrees of losses will occur, and even serious consequences will occur. For example, if the gate of a hydropower project cannot be closed in time due to hoist power supply, electrical control system or motor failure, a large amount of power generation resources will be wasted, and if it cannot be opened within a certain period of time, it may affect the flood discharge of the reservoir and may have an impact on the safety of the dam. When the power...

AI Technical Summary

Problems solved by technology

There is a time requirement for the opening and closing of the gate. If the gate cannot be opened or closed within a certain period of time, it will cause losses to varying degrees, and even serious consequences.

For example, if the gates of hydropower projects cannot be closed in time due to hoist power supply, electrical control system or motor failure, a large amount of power generation resources will be wasted. If they cannot be opened within a certain period of time, it may affect the flood discharge of the reservoir and may have an impact on the safety of the dam.

When the power supply or electrical control system of the hydraulic hoist fails, or the motor of the hoist fails, the hoist will not work and cannot be closed or opened within a certain period of time, which will cause various degrees of damage. loss

[0003] The emergency operation device of the hydraulic hoist on the market has the following problems: When performing an emergency operation, the emergency operation device cannot synchronously control the two hydraulic cylinders of the hydraulic hoist with high precision, resulting in the opening and closing of the double lifting point gate. Misalignment, deformation, jamming, etc.
