Abstract
The present invention discloses a wire rope descent control device, comprising a casing and a wire rope. A centrifugal friction decelerating device, a pulley decelerating device and a braking device are arranged in the casing. The centrifugal friction decelerating device comprises a friction sheave, a frisbee, a friction block and so on, the principle of which is using centrifugal force to make the friction block and the friction sheave joint together to produce friction to limit the rotary speed of the pulley. The pulley decelerating device slows down the speed through the friction between the pulley and the rope and the friction between the pulley and pulley. The braking device plays the locking role at the beginning of lowing, and plays the deceleration and braking role in the lowing process. The present invention is portable and smart. The two sets of decelerating devices make the descent control effect be better. The braking device makes safety coefficient be higher, so that the present invention is more reliable to use.

The invention has the beneficial effects as follows: light small and exquisite, two cover deceleration devices cooperate brake apparatus, make that the slow effect of falling is better, and safety coefficient is higher during use, and is more reliable.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of the centrifugal friction formula deceleration device among the present invention.
The specific embodiment
A kind of wire rope slow drop-down apparatus as shown in Figure 1 has a housing, and inside is provided with centrifugal friction formula deceleration device, pulley speed reducing device, brake apparatus.
Centrifugal friction formula deceleration device as shown in Figure 2 comprises frictional disk 5, flying disc 6, rotating shaft 7, brake pad 8, gear 9, travelling gear 10, gear ring 11, drive pulley 12, frictional disk 5 is a disc, be fixed on the outer surface of housing 1, be provided with the flying disc 6 of band rotating shaft 7 in the frictional disk 5, flying disc 6 is provided with the brake pad 8 that can radially slide, brake pad 8 can recline with the dead turn face of frictional disk 5, the radian on the friction limit of brake pad 8 is consistent with the radian of the dead turn face of frictional disk 5, make brake pad 8 like this when reclining the dead turn face, maximum friction area is arranged.The rotating shaft 7 of flying disc 6 is provided with gear 9, this gear 9 passes housing 1 with rotating shaft 7 from the outside, with travelling gear 10 engagements that are arranged on housing 1 medial surface, 12 of drive pulley are enclosed within the rotating shaft 7, drive pulley 12 is provided with a coaxial gear ring 11 on the one side of flying disc 6, this gear ring 11 and the engagement of travelling gear 10 inscribes.
As shown in Figure 1, the pulley speed reducing device comprises eccentric wheel 2, a pair of auxiliary pulley 3, a pair of leading block 4, eccentric wheel 2 is made up of interior wheel shaft 2-1 and outer pulley 2-2, interior wheel shaft 2-1 has the axis hole of an off-centre, and pass through this shaft hole sleeve on the fixed axis of housing 1, in outer pulley 2-2 is enclosed within on the wheel shaft 2-1, a pair of auxiliary pulley 3 is separately positioned on the both sides of eccentric wheel 2 by the fixed axis on the housing 1, and a pair of leading block 4 also is separately positioned on the both sides of eccentric wheel 2 by the fixed axis on the housing 1.
As shown in Figure 1, brake apparatus is made up of brake axle 13, braking spanner 14, and brake axle 13 is arranged on two housings 1 between the leading block 4, and passes housing 1 and fixedly connected with the braking spanner 14 that is arranged on housing 1 outside, has cornu on the brake axle 13.
As shown in Figure 1, the mode of connecting of steel wire rope 15 is: after an end of steel wire rope 15 enters from the opening position of housing 1, at first between the leading block 4 of a brake axle 13 and a side, pass, between this leading block 4 and eccentric wheel 2, pass again, take advantage of a situation then again and between the auxiliary pulley 3 of homonymy and eccentric wheel 2, to pass, then walk around drive pulley 12, between the auxiliary pulley 3 of opposite side and eccentric wheel 2, pass again, take advantage of a situation and between the leading block 4 of eccentric wheel 2 and this side, pass again, then between this leading block 4 and brake axle 13, pass, draw from the opening position of housing 1 at last.
When being affected under the gravity effect of steel wire rope the people, it drives drive pulley and rotates, gear ring on the drive pulley and then rotates, drive travelling gear, flying disc is given in transmission again, after the flying disc rotation, the brake pad that is arranged on the flying disc gets rid of cunning because of action of centrifugal force to avris, and the recline dead turn face of frictional disk of brake pad edge produces the rotating speed of force of sliding friction restriction flying disc, limited the rotating speed of drive pulley so conversely again, to reach the slow purpose of falling of slowing down, the flying disc rotating speed is high more, and the applying power of brake pad and dead turn face is big more, frictional force is just big more, and speed limit power is big more.
When steel wire rope is affected, eccentric wheel is subjected to the effect of the tensioning pressure of a side rope to be pressed towards opposite side, and the auxiliary pulley of the opposite side that reclines, the opposite side rope is sandwiched between the two pulley races, wheel shaft can not rotate around fixed axis again in this moment was eccentric, outer pulley then is rotated further around interior wheel shaft under the drive of rope, under the effect of the tensioning pressure of rope, eccentric outer pulley, auxiliary pulley, produce stronger frictional force between the rope three, add the effect of the frictional force between the outer pulley of eccentric wheel self and its interior wheel shaft, cause the pulley rotating speed to slow down, and rope formed serpentine between each pulley wear around, also strengthen the frictional force between rope and each pulley, and then also limited the rotating speed of whole assembly pulley, played the slow effect of falling of slowing down.
The rolling brake spanner, brake axle rotates thereupon, when forwarding certain angle to, the recline leading block of a side of the cornu on the brake axle, rope is clamped by both, relies on the effect of frictional force, makes rope not twitched, to reach the purpose of retarding braking again.
This wire rope slow drop-down apparatus use for the work high above the ground personnel or during high-rise dangerous situation escape use, wire rope slow drop-down apparatus hangs on the roll-over protective structure by its suspension ring, and the rope of drawing from cheese is connected with safety belt pass the internals of wire rope slow drop-down apparatus according to the above-mentioned mode of connecting after.At the braking spanner that can rotate wire rope slow drop-down apparatus at the beginning earlier that descends it is in the lock state, this moment, rope can not be twitched, and the personnel that can prevent like this, avoid meeting accident once hanging on the phenomenon that safety belt begins to glide firm.After ready, stir the braking spanner state that unlocks again, this moment, the people began to glide.In the decline process as when running into special circumstances and must stop falling, can realize the purpose of retarding braking by stirring the braking spanner again.
This wire rope slow drop-down apparatus is light small and exquisite, and the slow effect of falling is good, coefficient height safe in utilization.
