The utility model discloses a rackwork warp shock attenuation walking portion, including frame, epicyclic train subassembly, angle modulation device and walking assembly, the epicyclic train subassembly is two, is symmetrical arrangement, including sun gear, rocking arm, planetary gear and damping component, the damping component of epicyclic train subassembly links to each other with frame and rocking arm respectively, and the double rack of angle modulation device is in and meshes with it between two sun gears, and double rack follows the planet wheel rotation that the frame moved and drove the sun gear and meshes with it under the drive of screw rod and screw rod driving piece to drive and two planet wheel two continuous walking assembly do the antiport, thereby have realized the deformation of walking portion, when two walking assembly received external shock, because of damping component's existence, the rocking arm can be swung in certain limit elasticity for walking portion has damping performance. The utility model discloses still provide a fire control moving platform, can be used to design fire -fighting robot, warp shock attenuation walking portion including foretell rackwork.
