Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As Fig. 1, shown in Fig. 2, the present invention includes a bearing 1, one speed reducer 2 is fixedly connected with in the side at bearing 1 top, the opposite side at bearing 1 top is fixedly connected with a sedimentator mount pad 3, decelerator 2 input is connected with that a damping fan is slow falls system 4, decelerator 2 output connects the 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, main shaft 5 between 8 is fixedly connected with a wiring roller 9, 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 one by the housing 11 of 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, axle sleeve 13 external diameter is provided with some centrifugal-blocks 14, between each centrifugal-block 14 and housing 11, be provided with a circle driven member 15, between driven member 15 internal diameter and each centrifugal-block 14 external diameter, leave trickle gap.
In above-described embodiment, when electric fault electromagnetism brake holding out of hand system 5 works, centrifugal speed limiting clutch 10 can be utilized to be landed by the mode speed limit of mechanical friction, speed can be limited in risk range.
In above-described embodiment, as shown in Figure 2, the slow wiring roller 9 falling system of the present invention is as driving link, when being wrapped in lifting rope carrying weight on wiring roller 9, weight pulls lifting rope in gravitational effect acceleration, the torsion of lifting rope makes wiring roller 9 accelerate to rotate, the main shaft 6 that rotarily drives of wiring roller 9 together accelerates to rotate, the acceleration of main shaft 6 rotates and makes the centrifugal-block 14 of obvolvent on axle sleeve 13 in centrifugal speed limiting clutch 10 together accelerate 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 with adjacent driven member 15 under the influence of centrifugal force and rubs, and frictional force can form quadratic power increase doubly along with the continuous increase of speed, when the size of frictional force equals the weight of decline object, speed just can not continue to rise again, now weight will move with uniform velocity.To realize the effect controlling reduction of speed.
The using method of apparatus of the present invention is as follows:
Under normal condition, the slow wiring roller 9 fallen on equipment is wound with the lifting rope of hanging weight, when weight declines, under the effect of acceleration of gravity, wiring roller 9 is driven to accelerate to rotate, drive the main shaft 6 through wiring roller 9 to rotate, the rotation of main shaft 6 is ordered about and is connected to that damping fan on main shaft 6 is slow falls system 4 or electromagnetism brake holding system 5 works simultaneously.Damping fan delays the reaction force that the system of falling 4 work produces, along with the increase of weight decrease speed also constantly increases, until identical with the gravity of weight, weight is made to be in basic uniform descent state, generally, whole system normally can work along said process.If decrease speed exceeds setting value, the electromagnetism brake holding system 5 so receiving overspeed signal will be put immediately and stop, and to stop the further rising of speed, speed is still controlled in safe range.If when electromagnetism brake holding system 5 also cannot normally work, the speed of main shaft 6 will rise further, at this moment the centrifugal speed limiting clutch 10 be 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 large to the reaction force impelling centrifugal-block 14 to overcome its own system, start to produce frictional resistance with adjacent driven member 15, frictional force forms quadratic power increase doubly along with the continuous increase of speed.Until identical with the gravity of weight, weight is made to be at the uniform velocity state.
