Embodiment 1

[0014] A lifting or support device used for earthquake rescue. The lifting or support device is composed of a sphere 5 and four telescopic hydraulic cylinders 1; the telescopic hydraulic cylinders are combined together inside the sphere by pipe joints 2 and are in contact with the surface of the sphere. The four points form the four vertices of the front body inscribed by the ball; the supporting palm 3 on the top of the telescopic hydraulic cylinder is connected with the telescopic hydraulic cylinder through the ball pair 4. There is a supporting palm on the top of each telescopic hydraulic cylinder, and a force sensor 6 is arranged on it. When lifting or supporting, the force sensor is used to sense the force in each direction and give a feedback signal to control each expansion The amount of expansion and contraction of the hydraulic cylinder. The entire lifting or support device is connected to the accumulator 9 through the connecting pipeline 7 and the reversing valve 8. T...

Abstract

The invention provides a lifting or supporting machine for earthquake rescue and relates to the field of rescue, engineering application and the like, in particular to a special lifting or supporting machine needed in natural disasters such as earthquakes and the like. The lifting or supporting machine consists of a spherical body and four telescopic type hydraulic cylinders, wherein the telescopic type hydraulic cylinders are mutually connected in the spherical body by pipe joints, and four points where the four telescopic type hydraulic cylinders are contacted with the surface of the spherical body form four apex points of a regular hexahedron inscribed to the spherical body; the supporting palms on the top parts of the telescopic type hydraulic cylinders are connected with the telescopic type hydraulic cylinders by sphere pairs; and the top part of each telescopic type hydraulic cylinder is provided with a supporting palm provided with a force sensor. Under a condition of lower load, the lifting or supporting machine is used as a lifting machine to rescue people buried beneath collapsed buildings, and under a condition of bigger load, the lifting or supporting machine is used as a supporting machine to protect trapped persons from the secondary extrusion when the large-scale machinery is used for moving buried objects; and the lifting or supporting machine also has the advantages of simple structure, convenient operation, easy maintenance, big lifting or supporting force and strong environmental adaptability.

Description

【Technical Field】 [0001] The invention relates to the fields of rescue, engineering application and the like, and particularly relates to a special lifting or support device that is needed under natural disasters such as earthquakes. 【Background technique】 [0002] In response to severe natural disasters such as earthquakes that threaten people's lives and properties, governments and relevant scientific research institutions around the world are committed to the research and development of relevant rescue equipment. In the earthquake rescue, more achievements have been made in searching for trapped persons. A number of related equipment has been developed and widely used in countries around the world: (1) Life detectors, which mainly sense the ultra-low frequency emitted by the human body The electric field (produced by the heart) generated by the radio waves finds out the location of the trapped survivor. The ultra-low frequency electric field emitted by the human body can pene...
