The invention discloses a method for folding wearable lower limb assisting robots. The method is characterized by comprising detaching leg following support elastic components from assisting mechanical legs, and sequentially outwardly turning hinge centers of the upper end edges of hip joint rotation limiting discs and the lower portions of bosses by 90-degree angles by the aid of thigh folding components and shank folding components; outwardly and oppositely folding the assisting mechanical legs at the shank folding components; inwardly and oppositely folding the assisting mechanical legs at the thigh folding components; obtaining portable bodies of the wearable lower limb assisting robots. The wearable lower limb assisting robots are in initial states when central connecting lines of thigh connecting rods and shank connecting rods are at mutual coincidence positions. The method has the advantages that the wearable lower limb assisting robots can be turned into the portable bodies with compact structures and can be used with loading and transporting trolley cases, so that users can conveniently carry and store the wearable lower limb assisting robots in various modes, and daily activity and nursing requirements such as walking and stair ascending and descending of the users can be effectively met.

The present invention relates to a land-water-air three-purpose rotor aircraft, which comprises a body, a cabin cover, buoys, wheels, support rods, screw propellers and a motor, wherein the cabin cover is arranged on the body, a cabinet is formed between the cabin cover and the body, the buoys are arranged on both sides of the body, the wheels are arranged below the buoys and can be shrunk into the buoys, four groups of the screw propellers are arranged and are respectively arranged on the front ends and the rear ends of both sides of the body through the four support rods, the motor separately drives the four groups of the screw propellers to rotate, the support rod is a foldable rod, and the screw propellers are positioned at different positions when the support rods are folded. Compared to the aircraft in the prior art, the aircraft of the present invention achieves the applications in the three fields of land, water and air, has the multi-function, has advantages of simple structure arrangement and easy control, and further has advantages of substantially reduced cost, high running stability and high safety compared to other aircrafts.

A hydraulic fast forging unit adopting superposed oil supply of hydraulic pumps and high-pressure accumulators comprises a forging and pressing hammer, a main hydraulic cylinder, single-rod return stroke hydraulic cylinders, the main hydraulic pumps, the high-pressure accumulators, a medium-pressure accumulator, an oil tank and a valve control system. During the return stroke of the forging and pressing hammer, hydraulic oil in the single-rod return stroke hydraulic cylinders is supplied by the main hydraulic pumps, and stored oil in the main hydraulic cylinder is drained into the medium-pressure accumulator; during the idle-stroke fast dropping of the forging and pressing hammer, hydraulic oil in the main hydraulic cylinder is supplied by the medium-pressure accumulator independently, stored oil in the single-rod return stroke hydraulic cylinders is drained into the oil tank, and the main hydraulic pumps supply oil to the high-pressure accumulators; during rolling of the forging and pressing hammer, hydraulic oil in the main hydraulic cylinder is supplied by the main hydraulic pumps and the high-pressure accumulators in a superposed supply manner; during execution of the fast forging manner, hydraulic oil in the main hydraulic cylinder is supplied by the main hydraulic pumps and part of the high-pressure accumulators in a superposed supply manner, and during the fast return stroke, hydraulic oil of the single-rod hydraulic cylinder is supplied by the other part of the high-pressure accumulators; and control hydraulic oil of the valve control system is supplied by the high-pressure accumulators. The hydraulic fast forging unit has the beneficial effects of being simple in structure, small in equipment investment, high in energy utilization rate and the like.
