Voltage-controlled adaptive tall building escape self rescue device
Technical field
The present invention relates to a kind of slowly descending device for high building, and in particular to a kind of voltage-controlled adaptive tall building escape self rescue device.
Background technology
The fast-developing serious unbalance of China's fire-fighting emergent rescue outfit ability and skyscraper at present, first, the act of equipment
High and long shot lags behind the high development of skyscraper, and existing fire fighting truck water spray ability is usually 8 floors height, highest
Motor ladder reaches 15 layers or so, and often these rescue outfits can only " watchtower be heaved a sigh ";Second is that bulky, the mobility of equipment
Difference is easy to be influenced by road traffic, building surrounding enviroment;Third, the rescue ability of equipment is insufficient, existing motor ladder once lifts
2 to 3 people can only be succoured, once meeting fire in high buildings, live practical rescue needs cannot be met.
With China's industrialization, the continuous quickening of urbanization process, above-mentioned contradiction also becomes increasingly conspicuous, and data with existing is shown,
The situation that accelerates has been presented in some flourishing urban skyscraper fire incidents of China.In face of the above problem, people open in recent years
Many slowly descending device for high building are sent out.But current slowly descending device for high building relies primarily on friction mode and realizes slow drop, can not repeatedly weigh
It is multiple to use.For the more occasion of escape personnel, then there is being used for multiple times after, cause ramp-down device security and stability reduction,
Follow-up escape personnel can not safe escape.
For this purpose, we have invented voltage-controlled adaptive tall building escape self rescue device, energy is consumed in the way of hydraulic damping, and
According to escape loading capacity automatic adjustment oil buffer opening, decrease speed is made to be substantially constant at secure setting.
Invention content

With rotation;Guide ring 26 is nested on active bent axle 2, and dive key 30 is provided between active bent axle 2, to moving axis
Hold 28, transition rings 27 and type lever 13 slide axially;Bearing 28 is provided between guide ring 26 and transition rings 27, specifically
28 inner ring of bearing is connect with 26 outer ring of guide ring, and 28 outer ring of bearing is connect with 27 inner ring of transition rings;Baffle ring 29 is arranged in guide ring
On 26 outer rings, for preventing sliding axially for bearing 28;The song of the active between guide ring 26 and index dial 22 is arranged in spring 23
On axis 2, realize that the proportionate relationship of the rotating speed of active bent axle 2 and the aperture of hydraulic bjuffer 7 is adjusted.
As shown in figs. 1 and 4, dual redundant buffer gear includes the active song being connect with baffle 10, baffle 16 by bearing 18
Axis 2, copper sheathing 4, connecting rod 1, connecting rod cap 3, transition block 5, hydraulic bjuffer 7 and throttle valve adjuster 11.The both ends of active bent axle 2 point
Baffle 10, baffle 16 are not fixed on by bearing 18, further prevent active bent axle 2 from axially altering with the fixation of left and right end cap 17
It is dynamic;Connecting rod 1 forms a set of link mechanism with connecting rod cap 3, and two sets of link mechanisms are installed on active bent axle 2, in link mechanism
It is provided with the copper sheathing 4 being nested on active bent axle 2 between active bent axle 2 and plays lubricating action, connecting rod 1 is logical with hydraulic bjuffer 7
Cross the connection of transition block 5;Two hydraulic bjuffers 7 are fixed on by supporting block 9 on baffle 10, and two hydraulic bjuffers 7 are logical
It crosses two pairs of upper lower nuts 8 and is fixed on supporting block 9, throttle valve adjuster 11, throttle valve adjuster 11 and push-pull rod are installed in lower end
12 are connected, and throttle valve adjuster 11 can be made to rotate by push-pull rod 12, to realize that adjusting 7 throttle valve of hydraulic bjuffer opens
Degree.
The supporting block 9 is stepped, by integrally formed upper end rectangular block, intermediate rectangular block and bottom end rectangular block group
At wherein upper end rectangular block and intermediate rectangular block is provided with threaded hole;Upper end rectangular block, the intermediate rectangular block of supporting block 9 pass through gear
After straight slot in 10 phase of plate, bottom end rectangular block blocks baffle 10, and is threadedly coupled with baffle 10;Intermediate rectangular block and tune nearby
Section 7 phase of hydraulic bjuffer is fixed, and hydraulic bjuffer is stuck in intermediate rectangular block using lower nut in a pair 8;Upper end rectangle
Block is fixed with another adjusting 7 phase of hydraulic bjuffer, is similarly blocked upper end rectangular block using lower nut in a pair 8.
Supporting block 9 makes two pairs of nuts 8 of two fixed hydraulic buffers 7 in the presence of partly overlapping using a stepped design, to save
Space, and increase product strength.
As shown in figure 5, stepless regulating mechanism include by fixed plate 6 be fixed in supporting block 9 type lever 13 and
The type lever of connection and the push-pull rod 12 of throttle valve adjuster 11.The guide ring 26 of centrifugal feedback mechanism slides axially drive
Type lever 13 is swung, and to drive push-pull rod 12 to move horizontally, is finally realized and is adjusted 7 throttle valve opening of hydraulic bjuffer, under making
Reduction of speed degree maintains within the scope of secure setting, and step-less adjustment make decline during speed control it is finer and smoother, Bu Huicun
In pause and transition in rhythm or melody sense.
As shown in Figure 1, Fang Sheng mechanisms include steel wire rope 19 and noseplate 20, Fang Sheng mechanisms can accommodate two reversed steel wires
Rope 19, and separated by noseplate 20, avoid two strand steel wire ropes from mutually winding.Specifically:Steel wire rope 19 drives 2 turns of active bent axle
Dynamic, active bent axle drives centrifugal feedback mechanism rotation, and centrifugal feedback mechanism is then driven to be unfolded, final to realize speed tune
Section.
The aperture that 7 bottom end of the hydraulic bjuffer is provided with is for adjusting throttle valve initial opening and centrifugal feedback machine
Structure is adjusted in real time during declining, and two ways is combined realizes reaction type step-less adjustment decrease speed jointly.
Linear motion is converted to the reciprocating motion of the pistons of hydraulic bjuffer 7 by bent axle-connecting rod by the present invention, generates resistance
Torque breaks through Friction dissipation energy and is reused to realize to realize retarding braking.It is right in baffle 10 and baffle 16
Title is provided with half slot 15, and a people can the easy manipulation present apparatus.
Working principle of the present invention is as follows:
The weight of survivor acts on steel wire rope 19, and active bent axle 2 is driven to rotate, and is fixed on active bent axle 2 to drive
On index dial 22 rotate, while centrifugal globe 25 due to centrifugal force open, drive centrifugation bar 24 by guide ring 26 along guide flat
Key 30 slides axially, and guide ring 26 moves the type lever 13 that is transmitted to, and the type lever 13 for drives is swung, 13 lower end of type lever company
Push-pull rod 12 is connect, to drive push-pull rod 12 to move along a straight line, push-pull rod 12 drives 11 turns of the throttle valve adjuster of hydraulic bjuffer 7
It is dynamic, to realize the throttle valve opening aperture for adjusting hydraulic bjuffer 11;Meanwhile active bent axle 2 will be rotated and be converted by connecting rod 1
It is transferred to hydraulic bjuffer 7 at round-trip piston motion, hydraulic bjuffer generates flowed friction square, connecting rod 1 reacted on, to limit
The rotation of active bent axle 2 processed, is finally reached the effect braked in real time.
When 2 rotating speed of active bent axle is more than setting value, then by the above-mentioned course of work, final throttle valve adjuster 11 closes in real time
Small throttle valve opening increases the real-time moment of resistance, the velocity of rotation of limitation active bent axle 2;With should 2 rotating speed of active bent axle it is too low,
Then throttle valve adjuster can automatically real-time hold big throttle valve opening, reduce the real-time moment of resistance, and active bent axle 2 is made to be constantly in peace
In full range of set value.
