Abstract

The invention provides an automatic abut-joint hydraulic valve element, a hydraulic quick changing device and a rescue device. The automatic abut-joint hydraulic valve element, the hydraulic quick changing device and the rescue device are applied in the occasion that a hydraulic power oil path needs to be automatically in abut joint. Flush end face connection is adopted, in the valve element abutjoint process, a prepared abut-joint manner is adopted, a male joint end has a certain pre-abut-joint length, and the anti-pollution and anti-overflow aims in the abut-joint process can be achieved. The valve element can be used for the work accessory quick changing device in the emergency rescue device. The manual participation in rapid joint connection is solved, and high efficiency and safety of the rescue work can be ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic docking hydraulic valve core, a hydraulic quick change device and rescue equipment. 【Background technique】 [0002] Natural disasters occur frequently in our country. After a disaster accident occurs, the greatest role of emergency rescue equipment is to complete various complex rescue tasks in the shortest possible time and reduce the property losses of the affected people. Emergency rescue equipment must have the characteristics and functions of multi-function, high efficiency, and prevention of secondary personnel injury, so as to adapt to the operation requirements in complex environments and save people's lives and property. [0003] However, my country has not yet formed a complete and professional emergency rescue equipment system. When a disaster occurs, most of the rescue tasks are completed by construction machinery or rescue equipment equi...
