Problems solved by technology

[0003] The pressure of the existing hydraulic power station is 14MPa, the flow range is 30-40L / min, and the weight of the whole machine is more than 150kg. Due to the use of traditional materials, the integration of parts and components is low, the weight of the whole machine is large, it is inconvenient to carry, and it cannot be used for long-term heavy-duty work. In addition, the output flow of the existing models is too small, which cannot meet the needs of large input flow of some hydraulic tools, and the types of suitable hydraulic tools are limited.
[0004] At the same time, the existing hydraulic power station models cannot cool the high-temperature hydraulic oil for a long time, that is, it is not enough to reduce and maintain the oil temperature of the high-temperature hydraulic oil below the desired 80°C, and the oil temperature can exceed 120°C when working for a long time , when the oil temperature is above 100°C, the executive components connected to the hydraulic oil circuit, such as hydraulic shears, demolition tools, road excavation tools, hydraulic picks, wire hydraulic crimping pliers, hydraulic tree trimmers, etc., often Unable to work, and even cause safety accidents, because the higher the temperature of the hydraulic oil, the greater the pressure of the hydraulic oil, which may cause the pipeline to burst, or cause the executive components to collapse
If the hydraulic cooling capacity is increased on the basis of the original model, the engine power needs to be increased, which will inevitably lead to a substantial increase in the weight of the whole machine
[0005] At the same time, the output flow of the existing models is relatively small, which cannot meet the needs of large input flow of some hydraulic tools, and the types of suitable hydraulic tools are limited.

Abstract

The invention mainly belongs to the field of hydraulic driving power devices, and particularly relates to a movable hydraulic power station. Layout of parts is optimized, application is achieved by combining a light material and a new technology, and weight reduction of a whole machine is achieved comprehensively; in the aspect of a hydraulic system, a high-volumetric-efficiency main pump is selected, hydraulic element layout is optimized, an integral hydraulic integrated control valve is designed, an oil flow allocation function, a hand control valve, an overflow valve, an input connector and an output connector are integrally designed, the working efficiency of the hydraulic system is improved, and the effect that the output range of the flow is widened is achieved through the integrated control valve; in the aspect of a hydraulic heat dissipation system, aiming at the current situation that the continuous working time is long, and the load is large, the heat dissipation capacity of the hydraulic system is calculated and checked, a hydraulic oil radiator, a wind scooper, a fan and other models are newly designed, the structure is optimized, the heat dissipation capacity of the hydraulic system is effectively improved, meanwhile, the capacity and shape of a hydraulic oil tank are optimized, and finally, the effect that the weight of the whole machine is reduced efficiently, and the whole machine is light and portable is achieved.

Description

technical field [0001] The invention mainly belongs to the field of hydraulic drive power devices, and in particular relates to a mobile hydraulic power station. Background technique [0002] Hydraulic crushing drafts, hydraulic water pumps, hydraulic saws and various hydraulic hand-held tools for emergency rescue all need to use hydraulic power packs to provide driving force. [0003] The pressure of the existing hydraulic power station is 14MPa, the flow range is 30-40L / min, and the weight of the whole machine is more than 150kg. Due to the use of traditional materials, the integration of parts and components is low, the weight of the whole machine is large, it is inconvenient to carry, and it cannot be used for long-term heavy-duty work. In addition, the output flow of the existing models is too small, which cannot meet the needs of large input flow of some hydraulic tools, and the types of suitable hydraulic tools are limited. [0004] At the same time, the existing hyd...
