Between 11, maximum distance of the pin hole 17 apart from spacing collar 11 is more than the horizontal spacing between guide sleeve 4 and anti-fall piece 9.Spring 12
Bayonet lock 13 is released and is coordinated with the pin hole 17 in limiting stull 16, limiting stull 16 is formed into stable state, and realize self-locking, is carried
High stability.
In the present embodiment, the position of second double spiral groove 702 corresponding with the outside junction of screw rod 7 is set on rotary disk 14
It is equipped with to wear the straight slot 143 for connecing drawstring 6.Straight slot 143 is wrapped in convenient for drawstring 6 inside the second double spiral groove 702.
In the present embodiment, anti-fall piece 9 be provided with it is multigroup, and along elevator inner wall from top to bottom arranged at equal intervals install,
No more than 1/3rd of the height of car 8, guide sleeve 4 is open the spacing between anti-fall piece 9 described in upper-lower position two adjacent groups
The spacing being smaller than between two groups anti-fall piece 9 of sustained height between end face.Anti-fall piece 9 intensive layout, can effectively drop
The potential energy that low car 8 generates when falling reduces consequence and loss that energy impact is brought to the greatest extent, and guide sleeve 4 is with preventing
There are gaps between pendant block 9, ensure that elevator not generate interference in normal operation between guide sleeve 4 and anti-fall piece 9, ensure elevator
Normal operation.
In the present embodiment, the side that 301 inside of threading hole is contacted with hanger rope 10 is provided with arcwall face 302.Hanger rope 10 works
It is big with 302 contact area of arcwall face during tension, right angle contact is avoided, reduces the abrasion of hanger rope 10, improves service life.
The operation principle and advantage of the present invention：In actual use, when steel wire rope 1 works normally, hanger rope 10 is tensed,
Hanger rope 10 is made to be in exceptionally straight state, so as to be limited by cantilever 9 to screw rod 7, the stretch section 601 of drawstring 6 is kept to be in
Tensional state once steel wire rope 1 is broken, causes car 8 to fall, and the pulling force being applied at this time on hanger rope 10 disappears,
Hanger rope 10 is in relaxed state, disappears to the limit function of screw rod 7, and the stretch section 602 of drawstring 6 bounces back at this time, drives
Screw rod 7 rotates, and so as to which rotary disk 14 be driven to rotate, phase occurs between the arc surface of revolution 141 and idler wheel 15 on rotary disk 14
To rolling, due to the continuous increase of the radius of turn of the arc surface of revolution 141, squeezing roller 15 moves outward, drives limiting horizontal
Guide sleeve 4 is stretched out in support 16, and when the pin hole 17 in limiting stull 16 is moved to 11 underface of spacing collar, spring 12 pushes bayonet lock 13
It moves down, bayonet lock 13 is plugged on inside pin hole 17, formation stable state, and in 8 drop event of car, limiting stull 16 encounters electricity
During anti-fall piece 9 on stair shaft, the cars 8 of anti-fall piece of 9 pairs of whereabouts stop, while control car 8 entirely through limiting stull
16 are supported and fixed on anti-fall piece 9, avoid continuing to move down causing more serious accident.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Staff person is described in the above embodiment and specification to be only it should be appreciated that the present invention is not limited to the above embodiments
The preference of the present invention, is not intended to limit the present invention, and without departing from the spirit and scope of the present invention, the present invention can also
There are various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.Claimed model
It encloses and is defined by the appending claims and its equivalent thereof.
