Problems solved by technology

[0003] At present, the fire-fighting robots used for environmental detection and sampling work in fire and hazardous chemical explosion sites have not been designed with a deformable walking part with a shock-absorbing function. Therefore, a deformable robot walking part with a shock-absorbing function and It is very meaningful to use the mobile platform designed by this walking part, especially the fire-fighting mobile platform

Abstract

The invention discloses a screw driving deformation shock-absorption walking part. The screw driving deformation shock-absorption walking part comprises a rack, epicyclic gear train assemblies, an angle modulation device and walking assemblies. The two epicyclic gear train assemblies are arranged symmetrically and comprise sun gears, rotary arms, planet gears and shock-absorption elements. The shock-absorption elements are connected with the rack and the rotary arms correspondingly. A nut block of the angle modulation device is connected with one sun gear. A shaft seat block is connected with the other sun gear, the distance between the nut block and the shaft seat block can be changed under the action of a screw, the two sun gears, the planet gears meshing with the sun gears and the walking assemblies connected with the planet gears are driven to rotate reversely, and thus deformation of the walking part is achieved. When the two walking assemblies are subjected to outer impact, due to existing of the shock-absorption elements, the rotary arms can swing elastically within a certain range, and thus the walking part has shock-absorption performance. In addition, the invention further provides a firefighting movable platform which comprises the screw driving deformation shock-absorption walking part and can be used for design of a firefighting robot.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a shock-absorbing walking part driven and deformed by a lead screw and a fire-fighting mobile platform with the same, which can be used to design a fire-fighting robot. Background technique [0002] Mobile robots used in fields such as fire rescue, detection and investigation need to face complex terrain environments, so robots are required to have good terrain adaptability, passability and motion stability. Taking fire-fighting robots as an example, some fire-fighting robots need to complete the environmental detection and sampling work of fire and hazardous chemical explosion sites. In this way, fire-fighting robots need to enter explosion and fire sites with complex terrain, which requires fire-fighting robots to have good terrain passability. Some terrains require the robot to have a high clearance height to prevent obstacles from jamming the robot chassis; some terrains requi...
