A post-earthquake rescue self-balancing stretcher mechanism

Abstract

The invention discloses a post-earthquake rescue self-balanced stretcher mechanism. The post-earthquake rescue self-balanced stretcher mechanism is composed of hydraulic driven wheel walking mechanisms, a balance rectangular frame, a balance regulating frame and an all-direction self-balanced adjusting mechanism and a stretcher body structure, wherein a plurality of the hydraulic driven wheel walking mechanism are distributed at the bottom of the balance rectangular frame; the stretcher body structure is mounted above the balance regulating frame through a buffering device; the all-direction self-balanced adjusting mechanism is composed of a plurality of hydraulic cylinders and an internal circulating ball screw mechanism driven by a balance motor, the lower end of every hydraulic cylinderis hinged to the balance rectangular frame, the upper end of the hydraulic cylinder is fixed to the balance regulating frame, and the internal circulating ball screw mechanism is hinged between the balance rectangular frame and the balance regulating frame. The post-earthquake rescue self-balanced stretcher mechanism can measure the deflection angle of the center of gravity in the vertical direction on the basis of a gyroscope sensor, perform balance regulation on a support through ball screws to maintain high balance; the hydraulic driven wheel walking mechanisms achieves switching between afoot walking manner and a wheeling manner of the post-earthquake rescue self-balanced stretcher mechanism to enhance the environment adaptability of the post-earthquake rescue self-balanced stretchermechanism.

Description

technical field [0001] The invention relates to the technical field of post-earthquake rescue, in particular to a self-balancing stretcher mechanism with good stability mainly used for rescue work on complex road surfaces in earthquake areas. Background technique [0002] Earthquake disasters continue to occur frequently around the world, which brings great challenges to the current on-site rescue technology. Especially after a destructive earthquake, as a professional earthquake rescue worker, how to use scientific rescue methods and advanced technical equipment to rescue survivors and minimize losses is our top priority. However, the extremely harsh on-site rescue environment, such as frequent aftershocks, narrow gaps, dangerous building ruins, and even toxic and radiation environments, will greatly affect the efficiency and effectiveness of rescue, and often even threaten the lives of rescue workers. . Especially when rescuers find the injured, how to quickly and safely...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly aims at the problem that the terrain in the earthquake area is complex after the earthquake, and the rescue and transportation of the wounded are difficult, and provides a post-earthquake rescue self-balancing stretcher mechanism. The ball screw adjusts the balance of the bracket so that the stretcher bed body maintains a good balance. At the same time, the hydraulically driven wheel-foot walking mechanism enables the stretcher mechanism to realize the conversion of the foot and wheel walking modes and improve the environmental adaptability of the stretcher mechanism.
