Description
Technical field
The invention belongs to the Work machine technical field, a kind of specifically object elimination acceleration of gravity of landing that can make is stabilized in the biplane damping centrifuge speed limit implementation method of setting range with its reduction of speed, and utilizes the biplane damping centrifuge limiter of speed and the steady reducing device of the method design.
Background technology
Limiter of speed is an operation technique field device commonly used, and the typical products that limiter of speed uses is the high-rise life saving steady reducing device.Growing along with urbanization, incity, city high building is more and more, has caused series of new problems thus.Such as, the self-help escape problem when running into crisis situation (as fire, earthquake).Although leave emergency staircase when the high building architectural design, because number is many in the high building, and fire or earthquake may damage emergency staircase, and it can not normally be played a role.Therefore, a large amount of high-rise life saving products has appearred on the market.Simultaneously, also there are many technical schemes open in the document, such as hanging type rope ladder, climbing formula rope, lift staircase etc., a wherein common class is to adopt centrifugal friction formula structure, its structure mainly is by the steel wire rope that descends and on the wheel shaft that gear graduation drives a plurality of centrifugal of having friction material to be installed, and centrifugal is rubbed with shell inner periphery curved surface and to limit decrease speed when wheel shaft rotates at a high speed.The speed-limiting device of this structure and steady stopping device are the purpose that reaches safe reduction of speed, must increase frictional force, and technological means commonly used is nothing but the coefficient of friction that increases centrifugal weight or increase friction material.Because the existence of centrifugal gravity, a plurality of centrifugal can not provide equal centrifugal force simultaneously, influence the speed stabilizing effect when rotary work.Centrifugal weight is big more, and this influence is also big more.
Although the centrifugal governor patent (patent No.: 200420041461.5) on centrifugal, increased a cam of the applicant's application, this cam outside top brake-shoe when centrifugal is rotated, make its generation be several times as much as the pressure of centrifugal force, need not centrifugal reliability that can guarantee work of greater weight, but this does not change the speciality that its rubbing surface is a curved surface, in actual fabrication, this centrifugal curved surface friction structure is very high for the concentricity requirement of parts, difficulty of processing is bigger, performance is stable inadequately, easily produces concussion.
Another typical speed limit technology is ZL01238423.2, ZL02275011.8 and ZL01255973.3 patent, and all being increases frictional force by the mode that friction plate all is set at the rope sheave two ends, but its decrease speed of this structure can't be regulated automatically.
