The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
as Fig. 1, shown in Figure 2, the present invention includes a bearing 1, a side at bearing 1 top is fixedly connected with one speed reducer 2, the opposite side at bearing 1 top is fixedly connected with a sedimentator mount pad 3, decelerator 2 inputs are connected with a damping fan and delay the system 4 of falling, decelerator 2 outputs connect a side of electromagnetism brake holding system 5 endoporus, the opposite side of electromagnetism brake holding system 5 endoporus connects a main shaft 6, main shaft 6 two ends are respectively by a bearing block 7, 8 are rotatably connected on bearing 1, in diaxon bearing 7, be fixedly connected with a wiring roller 9 on main shaft 5 between 8, the other end of main shaft 5 is equipped with a centrifugal speed limiting clutch 10, centrifugal speed limiting clutch 10 is bolted to connection on centrifugal mount pad 3.
As shown in Figure 3, centrifugal speed limiting clutch 10 of the present invention comprises a housing 11 by bolt disassembly, housing 11 both sides are rotationally connected an axle sleeve 13 by bearing 12, axle sleeve 13 connects main shaft 6 by key, be provided with some centrifugal-blocks 14 at axle sleeve 13 external diameters, be provided with a circle driven member 15 between each centrifugal-block 14 and housing 11, leave trickle gap between driven member 15 internal diameters and each centrifugal-block 14 external diameters.
In above-described embodiment, when 5 work of electric fault electromagnetism brake holding out of hand system, can utilize centrifugal speed limiting clutch 10 to land by the mode speed limit of mechanical friction, can be with speed restriction in risk range.
in above-described embodiment, as shown in Figure 2, of the present invention delaying fallen the wiring roller 9 of system as driving link, when lifting rope carries weight on being wrapped in wiring roller 9, weight accelerates to pull lifting rope in gravitational effect, the torsion of lifting rope makes wiring roller 9 accelerate rotation, the main shaft 6 that rotarily drives of wiring roller 9 together accelerates rotation, the acceleration of main shaft 6 rotation makes that in centrifugal speed limiting clutch 10, the centrifugal-block 14 of obvolvent on axle sleeve 13 together accelerates to rotate, weight makes the rotary speed of wiring roller 9 also thereupon in continuous quickening under the impact of acceleration of gravity, and then make centrifugal-block 14 produce centrifugal force, centrifugal-block 14 produces friction with adjacent driven member 15 under the effect of centrifugal force, and frictional force can form along with the continuous increase of speed quadratic power increase doubly, when the size of frictional force equals to descend the weight of object, speed just can not continue to rise again, weight will move with uniform velocity this moment.To realize controlling the effect of reduction of speed.
The using method of apparatus of the present invention is as follows:
Under normal condition, be wound with the lifting rope of hanging weight on the slow wiring roller 9 that falls on equipment, when weight descends, under the effect of acceleration of gravity, driving wiring roller 9 accelerates to rotate, drive simultaneously the main shaft 6 pass wiring roller 9 and rotate, the rotation of main shaft 6 orders about that the damping fan that is connected on main shaft 6 is slow falls system 4 or 5 work of electromagnetism brake holding system.The slow reaction force that falls system's 4 work generations of damping fan, along with the also constantly increase of increase of weight decrease speed, until identical with the gravity of weight, make weight be in basic uniform descent state, generally, whole system can work along said process.If decrease speed exceeds setting value, the electromagnetism brake holding system 5 that receives so overspeed signal will put immediately and stop, and to stop the further rising of speed, speed still is controlled in safe range.When if electromagnetism brake holding system 5 also can't work, the speed of main shaft 6 will further rise, at this moment the centrifugal speed limiting clutch 10 that is connected with main shaft 6 is started working, centrifugal speed limiting clutch 10 each centrifugal-block 14 when High Rotation Speed produces centrifugal force, centrifugal force constantly increases along with the continuous increase of speed, until greatly to impelling centrifugal-block 14 to overcome the reaction force of self system, begin to produce frictional resistance with adjacent driven member 15, frictional force is along with the continuous increase of speed forms quadratic power increase doubly.Until identical with the gravity of weight, make weight be at the uniform velocity state.
