As shown in fig. 1 to 4, the elevator bucket slow-descending device comprises a falling prevention mechanism 1, a falling speed regulation mechanism 2 and a counterweight water tank 3, wherein the falling prevention mechanism 1 for clamping a falling prevention steel wire rope 10 when an elevator bucket 4 falls is arranged on an elevator bucket rack 5; after the hoisting bucket 4 is clamped and overhauled, a deceleration adjusting mechanism 2 for slowly descending the hoisting bucket 4 is arranged on a hoisting support frame 6 and is matched with an anti-falling steel wire rope 10; the counterweight water tank 3 is connected at the rear end of the anti-falling steel wire rope 10.
The anti-falling mechanism 1 comprises a first spring 7, a connecting rod 8, a brake block 9, an anti-falling steel wire rope 10, a limiting block 11 and a second spring 12. One end of a connecting rod 8 is connected with the elevator bucket rope wheel, the other end of the connecting rod is connected with the brake block 9, and the middle part of the connecting rod 8 is connected with the elevator bucket rack 5 through the first spring 7 and is hinged with a support on the elevator bucket rack 5. The stop block 11 is located below the brake block 9 and is connected to the bucket frame 5 by the second spring 12. The working principle of the anti-falling mechanism 1 is as follows: after the elevator bucket rope pulley loses the traction force of the lifting power device, when the elevator bucket 4 falls, the first spring 7 (which is in an original working state and extends) pulls the connecting rod 8 through contraction, so that the brake block 9 at the other end of the connecting rod 8 is driven to move inwards, and the brake block 9 and the fixed seat are reduced in distance and tightly hold the anti-falling steel wire rope 10; meanwhile, the limiting block 11 loses the pressing and holding effect of the brake block 9, the tightly-holding anti-falling steel wire rope 10 is ejected under the pushing of the second spring 12, the dual-safety function is achieved, and the rapid and safe hovering effect when the elevator bucket 4 falls is achieved.
