Referring to fig. 3 to 7, the centrifugal brake device 3 includes a speed reducer gear set 311 engaged with the wire rope drum 2, and a brake mechanism 32 engaged with the speed reducer gear set 311, wherein the brake mechanism 32 includes a brake rotating shaft 321, a brake gear 322 disposed at the periphery of the brake rotating shaft 321 and engaged with the speed reducer gear set 311, a brake slide 323 disposed at the periphery of the brake rotating shaft 321 and disposed on an end surface of the brake gear 322, a brake ring 324 disposed at the periphery of the brake slide 323, at least one centrifugal brake component 325 connected to a side edge of the brake slide 323 and disposed at an inner side of the brake ring 324, and an outer cover plate 326 fixing the brake ring 324 on an inner wall of the case 1, wherein the centrifugal brake component 325 includes a brake centrifugal block 3251 having one end embedded in the brake slide 323, a brake pad 3252 disposed at an outer side edge of the brake block 3251, and a brake pad 3252 disposed at an outer side, And an elastic member 3253 connected between the brake eccentric block 3251 and the brake slide 323.

Specifically, as shown in fig. 7 and 8, the centrifugal brake block 3251 mainly comprises an insertion block 32511 and an arc block 32512 integrally formed at an end of the insertion block 32511, wherein the brake slide 323 is provided with a movable slot 3231 for inserting the insertion block 32511, and as shown in fig. 9, the arc block 32512 is located on an outer side of the brake slide 323.

Meanwhile, an opening 325111 is opened at the end of the insertion block 32511, a tension spring locking pin 325112 is disposed on the opening 325111, the elastic member 3253 is a tension spring 3253', one end of the tension spring 3253' is connected to the tension spring locking pin 325112, and the other end is connected to the brake slider 323 through a screw 3254.

In this embodiment, the descending latch 47' is inserted into the outer cover 326 and extends to the side of the brake gear 322. When the descending lock pin 47' is inserted into the second positioning hole and locks the brake gear 322, the brake gear 322 is locked and cannot rotate, and the pinion 312, the gearwheel 313 and the drum gear 23 cannot rotate, so that finally, the wire rope drum 2 cannot rotate, and the wire rope 6 on the wire rope drum 2 cannot extend; when the descending lock pin 47' is pulled out from the second positioning hole, the locking function of the brake gear 322 is released, the brake gear 322, the small gear 312, the large gear 313 and the drum gear 23 are restored to rotate under the gravity action of the escaper, the steel wire rope 6 is stretched, and the manned basket 5 can carry the escaper to automatically descend.

When the escaper uses the high-rise escape device to escape from a high place downwards, the steel wire rope 6 is pulled downwards by the gravity of a user to enable the steel wire rope drum 2 to rotate, and the escaper automatically descends along with the manned hanging basket 5 along with the downward extension of the steel wire rope 6; meanwhile, the rotation of the drum gear 23 of the wire rope drum 2 sequentially drives the small gear 312, the large gear 313 and the brake gear 322 of the speed reducer gear set 31 to rotate, the brake gear 322 rotates to drive the brake sliding seat 323 to rotate, and the centrifugal brake component 325 rotates along with the rotation of the brake sliding seat 323; during the high-speed rotation of the brake slide 323, under the action of centrifugal force, the brake centrifugal block 3251 of the centrifugal brake assembly 325 flies outward a certain distance until the brake pad 3252 contacts the inner side of the brake ring 324, as shown in fig. 11, and at the same time, the tension spring 3253 'is pulled, and the tension spring 3253' is deformed; when the brake block 3252 contacts the inner side of the brake ring 324, since the brake ring 324 is fixed relative to the chassis base plate 11, friction is generated between the brake block 3252 and the brake ring 324, so that the overall rotation speed of the centrifugal brake assembly 325 is reduced, and the rotation speed of the brake slide 323 is reduced; the rotation speed of the brake slide 323 is reduced, so that the rotation speeds of the brake gear 322, the pinion 312, the large gear 313 and the roller gear 23 are reduced, and finally the rotation speed of the wire rope roller 2 is reduced, so that the wire rope 6 is slowly elongated, and the escaper slowly descends when the escaper is in fast contact with a target position (ground), thereby ensuring the safety of the escape process.
