Multi-freedom-degree automatic centering device, hydraulic quick switching device and rescue device

Abstract

The invention provides a multi-freedom-degree automatic centering device, a hydraulic quick switching device and a rescue device. The automatic centering device comprises a driving butt joint connection valve set, springs and a dynamic regulation swing frame. One end of the dynamic regulation swing frame is fixed to a work accessory, and the other end of the dynamic regulation swing frame is connected with the driving butt joint connection valve set through the springs. The dynamic regulation swing frame comprises a frame, limiting clamping grooves and spring limiting cylinders. The frame is used for supporting and fixing the driving butt joint connection valve set. The limiting clamping grooves are used for limiting the limit movement position of the driving butt joint connection valve set. The spring limiting cylinders are used for restraining the springs. The automatic centering device is used for solving the technical problems that in the butt joint connection process, position errors exist and centers do not coincide. Technical support is provided for the hydraulic automatic butt joint connection technology, and the multi-freedom-degree automatic centering device, the hydraulic quick switching device and the rescue device are simple in structure and clear in principle; internal components are mostly sheet metal parts and welded parts and are low in cost, firm and durable;and the multi-freedom-degree automatic centering device, the hydraulic quick switching device and the rescue device are suitable for emergency rescue work and engineering machinery work.

Description

【Technical field】 [0001] The invention relates to the technical field of engineering machinery, in particular to a multi-degree-of-freedom automatic centering device, 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 equ...
