Slippery fellow 142, slippery fellow 142 are slidably connected at the inside of annular groove 18.Rotary disk 14 is in turning course, and slippery fellow 142 is along annular groove 18
Circular arc trend is rotated, and 14 fixed-axis rotation of rotary disk is kept, and the arc surface of revolution 141 and idler wheel 15 is prevented to be detached from.
In the present embodiment, 4 upper surface of guide sleeve is fixedly installed the spacing collar 11 for limit, and inside spacing collar 11
It is connected to inside guide sleeve 4, spacing collar 11 is internally provided with bayonet lock 13, sets between bayonet lock 13 and the inside top surface of spacing collar 11
It is equipped with spring 12, limits and is provided with pin hole 17 corresponding with bayonet lock 13 in stull 16, pin hole 17 is located at idler wheel 15 and spacing collar
Between 11, maximum distance of the pin hole 17 apart from spacing collar 11 is greater than the horizontal spacing between guide sleeve 4 and anti-fall piece 9.Spring 12
Bayonet lock 13 is released and is cooperated with the pin hole 17 limited in stull 16, will the limit formation stable state of stull 16, and realize self-locking, mention
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 for wearing the through slot 143 for connecing drawstring 6.Through slot 143 is wrapped in inside the second double spiral groove 702 convenient for drawstring 6.
In the present embodiment, anti-fall piece 9 is provided with multiple groups, and arranged at equal intervals are installed from top to bottom along elevator inner wall,
Spacing described in the two adjacent groups of upper and lower position between anti-fall piece 9 is not more than the one third of the height of carriage 8, and guide sleeve 4 is open
Spacing between end face is less than the spacing between two anti-fall piece 9 of sustained height.Anti-fall piece 9 intensive layout, can effectively drop
The potential energy that low carriage 8 generates when falling, reduces energy impact bring consequence and loss to the greatest extent, guide sleeve 4 and anti-
It falls between block 9 there are gap, guarantees that elevator does not generate interference between guide sleeve 4 and anti-fall piece 9 when operating normally, ensure elevator
It operates normally.
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 when tension, right angle contact is avoided, the abrasion of hanger rope 10 is reduced, improves service life.
The working principle of the invention and advantage: in actual use, when wirerope 1 works normally, tensing hanger rope 10,
So that hanger rope 10 is in exceptionally straight state, to limit by cantilever 9 to screw rod 7, the stretch section 601 of drawstring 6 is kept to be in
Tensional state causes carriage 8 to fall once wirerope 1 is broken, and the pulling force being applied on hanger rope 10 at this time 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, so that 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 limit horizontal
Guide sleeve 4 is stretched out in support 16, and when the pin hole 17 in limit 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 carriage, limit stull 16 encounters electricity
When anti-fall piece 9 on stair shaft, the carriages 8 of anti-fall piece of 9 pairs of whereabouts are stopped, while controlling carriage 8 entirely through limit stull
16 are supported and fixed on anti-fall piece 9, avoid continuing to move down causing more serious accident.
The basic principles, main features and advantages of the present invention have 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
Preference of the invention, is not intended to limit the 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.
