Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of friction drive hoist of the present invention slides failure mechanical alarm device, including friction winding
Machine reel 1, reel frictional layer 2 ring cylinder 4, lower axle 5, ring cylinder frictional layer 6, spring leaf, steel ball and convex block；Friction drive hoist reel 1
With 2 CONTACT WITH FRICTION of reel frictional layer, reel frictional layer 2 is with ringing 6 CONTACT WITH FRICTION of cylinder frictional layer；The sound cylinder frictional layer 6 is sleeved on sound
On cylinder 4, ring cylinder 4 and be mounted in lower axle 5；The rotating speed of friction drive hoist reel 1 is transmitted through reel frictional layer 2 and sound cylinder frictional layer 6
To sound cylinder 4；Steel wire rope frictional layer 10 and 18 CONTACT WITH FRICTION of steel wire rope, steel wire rope frictional layer 10 are mounted on lower axle 5 by idler wheel 11
On, it is rotated synchronously with lower axle 5, the diameter for ringing cylinder frictional layer 6 is equal with the diameter of steel wire rope frictional layer 10；Lower axle 5 is equipped with bullet
Reed 14,14 end of spring leaf connection steel ball 8, rings 4 inner wall of cylinder and is equipped with convex block 9；Steel wire rope 18 generates slip, friction drive hoist
Reel 1 is with steel wire rope 18 there are relative velocity, and lower axle 5 generates difference with ringing the angular speed of cylinder 4, and steel ball 8 generates relatively with convex block 9
Speed, steel ball 8 tap convex block 9.Here a kind of specific installation example of said program is provided, reel frictional layer 2 is mounted on upper axis 19
On.Upper axis 19 is welded in both sides left support frame 3 and right support frame 17, and 5 both sides of lower axle pass through left bearing 20, right bearing 12, peace
In left support frame 3, right support frame 17,17 times left support frame 3, right support frame welding pedestals 7.It rings cylinder 4 and passes through lower axle
Inner ring 21, lower bearing ball 22 and lower axle bearing outer-ring 23 are held in the lower axle 5, reel frictional layer 2 by upper bearing (metal) ball 24,
Upper bearing (metal) inner ring 25 and upper bearing (metal) outer ring 26 are mounted on upper axis 19.All bearings are interference fits with axis in the present invention, are made
Bearing inner race moves together with axis.
On the basis of the said structure, convex block 9 of the present invention uses asymmetrically shape, and one side is that plane opposite side is bent
Face, thus steel ball from plane tap when from from curved surface tap when tone color be it is different, in this way can according to the sound heard
Determine the type for sliding failure.In order to leave the enough deformation spaces of spring leaf for, the present invention is provided with slot 15 in lower axle 5, will
Spring leaf 14 is welded in slot 15.Steel wire rope frictional layer of the present invention is sleeved on outside idler wheel 11, and idler wheel 11 is connected with lower axle 5 using key 13

In slot.Steel wire rope frictional layer is fabricated to groove, convenient for preferably being contacted with steel wire rope.
Operation principle of the present invention：Under nominal situation, the rotating speed of friction drive hoist reel 1 is identical with the speed of steel wire rope 18,
The rotating speed of friction drive hoist reel 1 is transmitted to through reel frictional layer 2 and sound cylinder frictional layer 6 and rings cylinder 4, rings 4 rotating speed of cylinder at this time with carrying
It is directly proportional to rise machine 1 speed of reel.Meanwhile the speed of steel wire rope 18 is transmitted to lower axle 5 through steel wire rope frictional layer 10, axis 5 at this time
Rotating speed is directly proportional to the speed of steel wire rope 18.As long as the diameter for ringing cylinder frictional layer 6 is equal with the diameter of steel wire rope frictional layer 10, i.e.,
Lower axle 5 can be ensured with ringing the rotational angular velocity of cylinder 4 always, you can ensure spring leaf 14 and steel ball 8 in lower axle 5 and ring on cylinder 4
Convex block 9 keep opposing stationary.
If slip accident occurs when steel wire rope 18 moves down, show that friction drive hoist reel 1 exists with steel wire rope 18
Relative velocity, then lower axle 5 generates difference with ringing the angular speed of cylinder 4, and steel ball 8 will generate relative velocity with convex block 9, if steel ball
8 tap generation tone color A from 9 plane of convex block, then are shown to be advanced slip, if steel ball 8 is tapped from 9 curved surface of convex block and generated another
Kind tone color B is then shown to be lag and slides.If slip accident occurs when steel wire rope 18 up moves, steel ball 8 also will be with convex block
9 generate relative velocity, at this time if steel ball 8 is tapped from 9 plane of convex block generates tone color A, are shown to be lag and slide, if steel ball
8 tap from 9 curved surface of convex block and generate another tone color B, then are shown to be advanced slip.
Certainly, above-described embodiment is only the preferred embodiment of the present invention, is specifically not limited thereto, on this basis can basis
Actual needs is made with targetedly adjusting, so as to obtain different embodiments.Since mode in the cards is more, this
In just no longer illustrate one by one.
