Description
Technical field
The present invention relates to a kind of high-altitude automatic descending device, refer in particular to a kind of portable automatic descending device that does not at the uniform velocity descend by external force interaction energy automatic slowly.
Background technology
The slow lowering means in present known high-altitude is by external force effect such as hoist engine etc.A kind of lowering means that needs fire fighter or mountaineer just can control that also has.This device is when human body gravity during 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 the professional must be by the frictional force of frequent adjustment with rope, the speed of coming the control personnel to descend.The ordinary person is to be difficult to operation without training.
And portable automatic descending device has remedied above-mentioned defective, and this device can be used for the ordinary person and does the escape device for high-rise buildings use, also can do fire-fighting, be to use when climbing the mountain or speedily carrying out rescue work.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of simple to operate, the portable automatic descending device that decrease speed is stable.
The technical solution adopted for the present invention to solve the technical problems is: portable automatic descending device comprises: rope, housing, lacing hole, cabinet, screw hole, rolling wheel, spring, tighten compositions such as bolt, change-speed gearing, hydraulic oil pump, oil circuit, check valve, overflow valve, regulator bolts, oil cylinder, piston push rod, brake pad, hook, handgrip, handgrip push rod, buckle, hinge.Housing adopts aluminum, with the weight of alleviator.Oil circuit is used closed system hydraulic power source loop.Spring is settled in the rolling wheel rear end, and spring rear end is settled and tightened bolt, is used for adjusting the tension force of spring.Because the tension force effect of spring, rolling wheel compresses rope all the time, and when object (human body) hung over this device decline by hook, rolling wheel rotated by the friction rope, and rolling wheel to the hydraulic pump gear, makes hydraulic pump works by gear drive.Hydraulic system promotes piston push rod and moves forward, and push rod one end is installed brake pad, and brake pad compresses rope, to increase frictional force.(brake pad is made with material wear-resisting and that coefficient of friction is big).When object (human body) when falling speed is too fast, rolling wheel rotates also fast more, and the hydraulic pressure pump impeller rotates fast more, and oil pressure is big more, and it is also big more that push rod ejects pressure, makes the frictional force of push rod and rope generation big more, causes falling speed to be slowed down.Cross when slow when object (human body) falling speed, the rolling wheel rotating speed reduces, and the oil cylinder internal pressure lowers, and push rod top power reduces, and also reduces with rope frictional force, and causing to fall and break speeds up.The two is restrained mutually, makes object (human body) can be adjusted to the state that at the uniform velocity descends automatically.Overflow valve is set to and can adjusts, and a regulator bolts is established in the overflow valve outer end, by manual adjustment overflow valve oil-out size, also can control object (human body) decrease speed.Principle is: when object is heavier (when perhaps needing to slow down decrease speed), regulator bolts reduces the oil pump capacity of overflow valve to inward turning, and the oil cylinder internal pressure is increased, and frictional force is increased, and decrease speed slows down.When object is light (when maybe needing to accelerate decrease speed), regulator bolts increases the overflow valve opening to outward turning, and the oil cylinder internal pressure reduces, and frictional force reduces, and decrease speed accelerates.Regulator bolts appearance and housing appearance are established scale, and graduation mark is respectively object (or human body) weight and decrease speed.
Handgrip is except that doing the handle use, also play standby, auxiliary brake effect, handgrip is located at housing two sides, push rod and brake pad are installed in the middle of the handgrip, rotate by handgrip, make handgrip push rod two ends to the extruding of rope direction, increase the frictional force between push rod and the rope, make object (or human body) in the decline process, adjust decrease speed as required.Handgrip plays braking action when the beginning landing in addition.
By the screw hole on the housing, fixing portable automatic descending device with body of wall or other fixtures, with the rope pulling rolling wheel is rotated, just become a kind of fixed automatic descending device.
Since steel wire rope, nylon rope, coefficient of friction differences such as the rope made of hemp, oil cylinder working-pressure is also answered corresponding adjustment, and the apparent scale of regulator bolts appearance and housing also should corresponding adjustment.
The invention has the beneficial effects as follows: utilize the gravitional force of object, drive the hydraulic pump works power that creates friction, the object decrease speed is slowed down or be adjusted to the state that at the uniform velocity descends automatically.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment 1: install: in Fig. 4, hydraulic pump 8, rolling wheel 12, spring 11, change-speed gearing 9, oil cylinder 7, piston push rod 3 parts such as grade make up mutually, pack in housing 1 cabinet 24, land from aerial suspension cord 19, housing 1 merges with housing 18 usefulness buckles 20,21, rope 19 enters in the lacing hole 14, and rolling wheel 12 compresses rope 19, and spring 11 is compressed.Screw handgrip 16 then, make portable automatic descending device be in braking state (as Fig. 3).
Is example to hang 100 kilograms than weight body (human body), and in Fig. 3, regulator bolts 5 rotates on 100 kilograms the scale, and object (human body) hangs on the portable automatic descending device by hook 13.Slowly rotary handle 16 is unclamped parking brake, and object begins to descend, and rolling wheel 12 begins to rotate, hydraulic pump 8 beginning pump oil, because the oil pump capacity of 100 kilograms of scale overflow valves 4 is less, in-cylinder pressure is bigger, and frictional force is also bigger.When frictional force and weight weight were close, human body began slow decline.
With the tenesmus of 20 kilograms of human bodies is example, and in Fig. 3, regulator bolts 5 rotates on 20 kilograms the scale, and human body hangs on the portable automatic descending device by hook 13.The parking brake that comes up, human body begin to descend, and rolling wheel 12 begins to rotate, and hydraulic oil 8 pumps begin pump oil, and in-cylinder pressure increases, and frictional force also increases, and when frictional force and human body weight were close, human body began slow decline.
In Fig. 3, the escape personnel removes and uses automatic decline function, and the standby auxiliary brake of also available handgrip slows down the human body decrease speed.Right handle turns clockwise, and a left side makes handgrip push rod 15 to the extruding of rope 19 directions being rotated counterclockwise, and to increase frictional force, reaches braking effect.On the contrary, with rightabout rotary handle 16, frictional force reduces, and human body descends again automatically.
The present invention used in the time of can also being used for work high above the ground or mountain-climbing and speedily carrying out rescue work, and adjusted the oil-out size of overflow valves 4 in the decline process at any time by regulator bolts 5, adjusted the fast, slow of decrease speed or stopped.When regulator bolts 5 was threaded to the zero graduation position, overflow valve 4 was closed, oil cylinder 7 internal pressures surges, piston push rod 3 top power also increase, when frictional force greater than object (human body) gravity, portable automatic descending device stops gliding.(stop the back pump impeller and do not work, check valve 6 is closed, and oil pressure remains unchanged in the cylinder).
When stopping back back-out regulator bolts 5, overflow valve 4 is fuel-displaced, and oil cylinder 7 internal pressures reduce, and frictional force is reduced, and object is made the decline state again.
