Description
Technical field
The invention belongs to elevator safety facility technology field, and in particular to a kind of parachute-type of elevator slows down fill safely
Put.
Background technology
Above mentioned elevator refers mainly to oblique elevator.Parachute-type deceleration dress safely is set on upper and lower vertical row elevator
The technical information put can be seen in disclosed Chinese patent literature, typical as patent of invention publication No. CN105752803A is pushed away
" a kind of elevator with parachute " recommended and patent of invention publication No. CN105621207A provide " a kind of security formula cell is special
With lift car ".The former technical scheme in this two patents is：Parachute box is provided with car top, in parachute box
Parachute is inside provided with, the width of hoistway is more than the diameter of parachute, and the bottom of parachute is fixed on the outer roof of car, parachute
Switch be located in car.Technique effect is as described in the 0007th section of its specification：Parachute can be beaten in Lift out of order
Open, slow down the speed of falling of car, reduce the accident extent of damage, be particularly suitable for skyscraper.
But make a general survey of the specification of aforementioned CN105752803A in full, do not read the tool for seeing parachute-type safety speed reducer
How body structure, such as release a parachute in time in elevator faults, and for example how by parachute in the stand-by state reliably
Control is in parachute case（Patent claims parachute box）It is interior, how to give safety to signal in the moment that elevator drops by electric life controller
Deceleration device, how to ensure that parachute is able to parachute case, etc. of quickly scurrying out.Additionally, CN105752803A will open landing
The switch of umbrella case be arranged at it is seemingly worthless in car, once because occupant is not intended to touch will there is improper enabling
Situation, not only causes false alarm to occupant, and makes troubles to elevator management side.Further, lose in car in dangerous generation
During control tenesmus, switching manipulation is at least had the following disadvantages using manual mode：Because car tenesmus is sent out with generally having no sign
It is born in a flash, has perhaps fallen not yet when occupant reacts, and because even occupant has reacted, due to touching out manually
Close existence time poor, thus can not prove effective within the very first time, also as generally during elevator tenesmus, occupant often locates
In the nervous and panic states of height, the action of Push switch can't be immediately made.
Further, since aforementioned CN105752803A and CN105621207A are both for for vertically row elevator
, there is no enlightening significance thus for oblique elevator, and CN1056210207A equally exists the aforementioned of CN105728203A
Various symptims and signs of deficiency.
As is known in the industry, aforesaid oblique elevator is main but not assigns with being definitely limited to and is enclosed within visit scenic spot especially layer
The domatic elevator in the mountain region of mountains in a range rows of mountains, this elevator equally can be seen in disclosed Chinese patent literature, such as
CN201494989U（A kind of oblique elevator）、CN102756967A（A kind of counterweight without guide rail oblique elevator）、
CN203306882U（A kind of car automatically adjusts horizontal device）And CN203976173U（The double car oblique elevators of counterweightless）Deng
Deng.
In sum, it is showed no in China and foreign countries' patent disclosed so far and non-patent literature and all is suitable for oblique elevator
Parachute-type safety speed reducer technical information, technical scheme described below is to produce under this background
's.

Push pedal 41 is fixed and limited by the nut 44211 that limits on the group fixation plate bolt 4421 is screwed.
Applicant combines the course of work that Fig. 1 to Fig. 3 describes the present invention, when car body 1 as shown in Figure 1 is in normal
During the state of operation, because the speed of fifth wheel 82 of the structural system of velocity measurement mechanisms 8 is in normal velocity interval, one group of centrifugation
Hammer 84 be enough to draw 842 to hold by centrifugal hammer, and velocity measurement mechanisms 8 will not act on securing rod controlling organization 6, that is to say, that one group of centrifugation
Hammer 84 will not go the centrifugal hammer strike pulley 68 of the structural system for hitting securing rod controlling organization 6, dead bolt 621 to fasten with a bolt or latch into securing rod
In 44 lock tongue cavity 441, in compressing and the state of energy storage, parachute 7 is pushed away one group of spring 5 by control with rounding state in slip
Between plate 41 and chamber door 32.
When the situation for occurring that the unexpected such as pull rope 9 for for example occurring having already mentioned above ruptures or traction machine is out of control etc
When, car body 1 downward disease will be slipped on a pair of diagonal guide rails 21（Disease is slided）, now because of the speed abruptly increase of fifth wheel 82, one
The centrifugal force of group centrifugal hammer 84 is significantly increased, and is run off under the pulling force for overcoming centrifugal hammer extension spring 842（Also can claim " throwing away "）
The wheel rim of fifth wheel 82, while centrifugal hammer strike pulley 68 is clashed into strike, is driven on push rod 67 by centrifugal hammer strike pulley 68
OK, drive push rod adjustment connector 66 up by push rod 67, lever is driven by it while push rod adjustment connector 67 is up
65 towards push rod 67 one end（Left end shown in Fig. 3）It is up, and one end that lever 65 is hinged with pitman coupling 64（Fig. 3
Shown right-hand member）Dip down pendulum, drives pitman coupling 64 descending, drives pull bar 62 descending by pitman coupling 64, pull bar 62
Upper end dead bolt 621 just exit chamber door opener 4 structural system securing rod 44 lock tongue cavity 441, now previously
The restoring force effect of one group of spring 5 in compression and energy storage state is lower to promote slip push pedal 41 to follow aforesaid front tank wall simultaneously
Upper and lower sliding groove 33a, 33b and rear box wall upper and lower sliding groove 34a, 34b are moved towards the direction of chamber door 32, so as to by a pair
Upper connecting rod 43 and a pair of lower links 44 promote the first chamber door 321 and the second chamber door 322, make first, second chamber door 321,322
Open, just speed is opened to be previously in the parachute 7 of rounding state, plays the speed of service for significantly slowing car body 1, it is to avoid
Accident occurs.
In sum, the technical scheme that the present invention is provided compensate for the shortcoming in prior art, favorably accomplish invention
Task, has faithfully cashed the technique effect referred in the superincumbent technique effect hurdle of applicant.
