Abstract
An automatic hydraulic slow descent device comprises a rope, a handle, a shell, a rolling wheel, a gear, a hydraulic pump, a single-way valve, an overflow valve, a pressure adjusting valve, a hook, an oil cylinder and an oil path. A closed type system hydraulic source loop is adopted in the oil path, and after the rolling wheel is wound by the rope, the rope penetrates the two ends of the shell; when an object (human body) is hung on the device through the hook to descend, the rope drives the rolling wheel to rotate, and the rolling wheel is transmitted to the hydraulic pump through the gear to work; and when the object (human body) descends, the rolling wheel drives the hydraulic pump to work, and the slow descent device descends at the constant speed.
Description
Technical field
The present invention relates to a kind of high-altitude automatic escape, refer in particular to not by a kind of automatic hydraulic descending lifeline of External Force Acting energy automatic slowly uniform descent.
Background technology
The slow lowering means in current known high-altitude passes through External Force Acting, a kind of lowering means needing fire fighter or mountaineer to manipulate also had, this device is when human bady gravitational is greater than rope frictional force, the acceleration that gravity produces makes object (personnel) lapse rate more and more faster, and when object gravity is equal to or less than rope frictional force, object or person person can hover in midair again, so professional by often adjusting the frictional force with rope, must carry out the speed that controllers declines.Ordinary person is be difficult to operation without training.
And automatic hydraulic descending lifeline compensate for above-mentioned defect, this device can be used for ordinary person and makes escape device for high-rise buildings and use, and also can do fire-fighting, be use when climbing the mountain or speedily carry out rescue work.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of simple to operate, the automatic hydraulic descending lifeline that decrease speed is stable, the technical solution adopted for the present invention to solve the technical problems is: automatic hydraulic descending lifeline comprises: rope, hand handle, housing, roller, gear, hydraulic pump, check valve, overflow valve, pressure regulator valve, hook, oil cylinder, oil circuit, oil circuit closed system hydraulic pressure circuit, rope runs through housing two ends after being wound around roller, when object (human body) hangs over the decline of this device by hook, rope drives roller to rotate, roller by gear drive to hydraulic pump works, operation principle is, when object (human body) falling speed is too fast, roller rotates to be accelerated, hydraulic pump rotates to be accelerated, oil pressure strengthens, due to the restriction of oil-out oil pump capacity size, hydraulic pump does uniform rotation, descending lifeline uniform descent.Overflow valve is set to adjustable, and a regulator bolts (pressure regulator valve 9) is established in overflow valve outer end, manually can adjust overflow valve oil pump capacity size, and when pressure regulator valve leaves large, oil-out oil pump capacity increases, and hydraulic pump rotates and accelerates, and descending lifeline uniform descent accelerates.Pressure regulator valve leaves hour, and oil-out oil pump capacity reduces, and hydraulic pump rotates slack-off, and descending lifeline uniform descent is slack-off.During closing pressure-regulating valve, oil cylinder working-pressure surges, and hydraulic pump stops operating, and roller stops operating, and descending lifeline stops declining.
The invention has the beneficial effects as follows: the gravitional force utilizing object, drive hydraulic pump works object decrease speed is slowed down or is automatically adjusted to uniform descent state.
Accompanying drawing explanation
Fig. 1 is the fundamental diagram of automatic hydraulic descending lifeline
In figure 1, rope; 2, hand handle; 3, housing; 4, roller; 5, gear; 6, hydraulic pump; 7, check valve; 8, overflow valve; 9, pressure regulator valve; 10, hook; 11, oil cylinder; 12, oil circuit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment 1: install: each parts (hydraulic pump 6, roller 4, gear 5, oil cylinder 11, parts such as oil circuit 11 grade be combined with each other) load in housing 3, land from aerial suspension cord 19, rope 1 enters in housing 3 and is wound around roller 4, closing pressure-regulating valve 9, object (human body) hangs in hook 10.During decline, slowly open pressure regulator valve 9, roller 4 starts to rotate, and hydraulic pump 6 starts pump oil, and object starts uniform descent.During closing pressure-regulating valve 9, oil cylinder 11 pressure surges, and hydraulic pump 6 stops operating, and roller 4 stops operating, and descending lifeline stops declining.
The present invention can also be used for using when work high above the ground or mountain-climbing are speedily carried out rescue work, and is adjusted the oil pump capacity size of overflow valve 8 in decline process at any time by pressure regulator valve 9, adjusts the fast, slow of decrease speed or stops.
Embodiment 2: housing 3 is fixed on high-altitude or body of wall, object hangs on rope 1, drives roller 4 to rotate, just become a kind of fixed automatic hydraulic slow descending device when rope 1 declines.(operation principle is identical with embodiment 1).
