Abstract
Provided is a multifunctional hydraulic expansion type rescue device. According to the multifunctional hydraulic expansion type rescue device, the hydraulic transmission principle and the plane four-bar linkage principle are used, output force of a hydraulic cylinder serves as power, an expansion device, namely, a supporting arm beam, is opened or contracts, a safe living space is provided for trapped people in earthquakes, other collapse accidents and traffic accidents in a supporting mode, trapped people are prevented from the secondary injury, provision can be supplemented for trapped people, the effective rescue time is prolonged, and more life chances are gained for trapped people, and then trapped people can be rescued through cooperation between the multifunctional hydraulic expansion type rescue device and other rescue devices. The multifunctional hydraulic expansion type rescue device mainly comprises the expansion device comprising a connecting disk and the supporting arm beam, the hydraulic cylinder, a control valve, a hydraulic pump and a hydraulic lock; please see the specification for the details of the multifunctional hydraulic expansion type rescue device.
Description
Technical field:
Patent of the present invention relates to a kind of multifunction hydraulic expanding rescuing device.
Background technology:
There is no this kind of multifunction hydraulic expanding rescuing device both at home and abroad.
Summary of the invention:
This kind of multifunction hydraulic expanding rescuing device, utilizes the principle of hydrostatic drive and four-bar linkage, relies on the flexible expander (hold-down arm beam) that makes of piston-type hydraulic cylinder to strut and pack up.
Patent of the present invention solves the technical scheme that its technical matters adopts: 1, the design of expander, 2, the selection of the Hydraulic Elements such as design 3 of hydraulic efficiency pressure system, Hydraulic Pump, hydraulic actuating cylinder, control cock, 4, the Installation and Debugging of whole equipment.The specific embodiment: rely on the flexible expander (hold-down arm beam) that makes of piston-type hydraulic cylinder to strut and pack up.
Patent beneficial effect of the present invention: this equipment has been filled up the blank of domestic and international this kind of rescuing device, it utilizes the principle of hydrostatic drive and four-bar linkage, relies on the flexible expander (hold-down arm beam) that makes of piston-type hydraulic cylinder to strut and pack up.For the captive in earthquake, traffic accident, various cave-in accident, prop up the space that a safety is survived, avoid being subject to secondary injury; And can replenish the provisions to it, extended effective rescue time, for captive has won more life, and then coordinate and rescue captive with other wrecking equipment.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, patent of invention is further illustrated.
Fig. 1 is structure and the fundamental diagram signal of patent of invention.Fig. 2 terminal pad schematic diagram
Fig. 3 is hold-down arm girder construction schematic diagram.
1. by pass valves in Fig. 1,2. hold-down arm beam, 3. pipe link, 4. terminal pad, 5. hydraulic actuating cylinder, 6. hydraulic control one-way valve, 7. change-over valve, 8. Hydraulic Pump.
On four hold-down arm distribution terminal pads of this multifunctional hydraulic expanding rescuing device, during the stretching out of hydraulic cylinder piston rod, expander (hold-down arm beam) is strutted, during retraction, expander (hold-down arm beam) is packed up.
the specific embodiment:
In Fig. 1, the highly pressurised liquid that first hydraulic hand-pump 8 produces is through having the right position of change-over valve, hydraulic control one-way valve 6 to arrive the right chamber of hydraulic actuating cylinder, and promotion piston is moved to the left expander (hold-down arm beam 3) is strutted.After rescue, change-over valve is got to left position highly pressurised liquid through having the left position of change-over valve, the left chamber of hydraulic control one-way valve hydraulic actuating cylinder feed liquor, and piston moves right and drives expander (hold-down arm beam 3) to shrink.
Claims (2)
