Obstacle-crossing rescue robot based on parallel mechanisms

Abstract

The invention relates to an obstacle-crossing rescue robot based on parallel mechanisms. The obstacle-crossing rescue robot comprises a rescue stretcher, an ambulance chassis, six-DOF (degree of freedom) parallel mechanisms, four planet gears, a three-level damping clutch, four dampers and two illuminating lamps, wherein the rescue stretcher is located above the ambulance chassis; the six-DOF parallel mechanisms are located at the front end and the rear end of the ambulance chassis and connected with the rescue stretcher, limited assigned yielding motion and effective bearing of push rods relative to the ambulance chassis and the rescue stretcher can be realized, the support performance of the push rods can be effectively improved, and the reliability, the stability and the safety of the rescue stretcher are improved; the four planet gears are driving wheels at the ambulance chassis, the height of the ambulance chassis can be effectively increased, and an obstacle is crossed rapidly; the damping clutch is mounted at the rear end of the ambulance chassis; the four dampers are located below four corners of the rescue stretcher; the two illuminating lamps are located at the front end of the ambulance chassis and can be used for illumination at night, and the driving safety is improved.

Description

technical field [0001] The invention relates to a medical mechanical device, in particular to an obstacle-surpassing rescue robot based on a parallel mechanism. Background technique [0002] At present, in the world, there are often cases where ambulances delay the treatment of patients due to roadblocks. With the development of the city, various communities often set up roadblocks at the entrance of the community. When a patient needs emergency rescue, the existing ambulance cannot pass through due to the low chassis, which delays the patient's precious rescue time. The existing ambulance also has the problem of poor damping effect. At this point, a kind of structure is simple, easy to use, can cross the roadblock fast, and the ambulance that travels steadily becomes social needs. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides an obstacle-surpassing rescue robot based on a parallel mechanism, ...
