Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
A kind of elevator with anti-fall device 20 as shown in Fig. 1 ~ 3, including square carriage 1, elevator 2, traction electric machine
3rd, steel wire rope 4, in the vertical elevator 2, the traction electric machine 3 pushes up the carriage 1 installed in the elevator 2
End, the traction electric machine 3 draw the carriage 1 by the steel wire rope 4 and move up and down vertically.
It is symmetrical axisymmetric anti-fall device 20 that a pair is further included in the elevator 2 with the steel wire rope 4, described anti-fall
Device 20 includes locking board 5, locking spring 7, anti-fall plate 8, locking line 10, fixed block 11, bar knife 12, movable plate 13, flat spring
14th, barrier plate 15, supporting rod 16, drawstring 18.
The anti-fall plate 8 is located at outside the carriage 1 and is fixed on vertically on the bottom face of the elevator 2, described anti-fall
Plate 8 is parallel to the carriage 1 lateral surface adjacent with 1 railway carriage or compartment of carriage door.
A plurality of acclivitous horizontal locking groove 9 is offered on 8 medial surface of anti-fall plate.
The locking board 5 is hinged on and on anti-fall corresponding 1 lateral surface of carriage of plate 8, the locking board 5 pushes up
It is fixed with end face and the corresponding locking pin 6 tilted down of the locking groove 9.
The locking spring 7 is fixed on and the anti-fall plate 8 positioned at the lower section of locking board 5,7 one end of the locking spring
On corresponding 1 lateral surface of the carriage, locking 7 other end of spring is fixed on the lower face of the locking board 5.
10 one end of the locking line is fixed on the upper surface of the locking board 5, and locking 10 other end of line is fixed on
On the fixed block 11, the fixed block 11 is fixed on the outer end face of the carriage 1.
The bar knife 12 is fixed on positioned at the surface of the locking line 10 and the vertical locking line 10, the bar knife 12
On the lower face of the movable plate 13.
The movable plate 13 is fixed on the outer end face of the carriage 1 by being fixed on the flat spring 14 of its lower face
On.
For the barrier plate 15 directly over the movable plate 13, the supporting rod 16 is fixed on the carriage 1 vertically
On outer end face, it is described that 16 other end of supporting rod passes through the vertical rod through-hole 17 opened up on the movable plate 13 to be fixed on
On the lower face of barrier plate 15.
Described 18 one end of drawstring is fixed on the upper surface of the movable plate 13, and 18 other end of drawstring passes through the resistance
The rope through hole 19 opened up on baffle 15 is fixed on the steel wire rope 4 of the top of barrier plate 15, the anti-fall device 20
The drawstring 18 is each attached to the same place of the steel wire rope 4, and the reason for being fixed on same place is to prevent drawstring 18 from drawing inclined steel wire
Rope 4 and influence elevator normal operation.
During elevator normal operation, the distance of bearing of the drawstring 18 on the steel wire rope 4 to the rope through hole 19
With the steel wire rope 4 to it is described rope through hole 19 distance difference be more than 12 edge of a knife of bar knife to it is described locking line 10 away from
From.When i.e. steel wire rope 4 breaks above bearing, bar knife 12 is made in itself and the common of 14 pulling force of 13 gravity of movable plate and flat spring
Under, quickly fall to locking line 10, because the drawstring 18 of symmetrical anti-fall device 20 is each attached at one, when two drawstrings 18 are two
When being drawn as being located at same straight line between rope through hole 19, two drawstrings, 18 length between two rope through holes 19 is exactly steel when steel wire rope 4 is not disconnected
For cord 4 to the rope twice of 19 distance of through hole, 12 edge of a knife of bar knife is exactly above-mentioned difference to locking 10 drop of line, this
Only guaranteed difference is more than 12 edge of a knife of bar knife to the distance for the line 10 that locks to sample, and bar knife 12 can just chop disconnected locking line 10, final locking
Pin 6 can be just caught in locking groove 9, subtract pendant to carriage 1 of falling to realize.
In the present embodiment, locking line 10 is made to guarantee to overcome to lock the pulling force of spring 7 of plastic material and pulls open lock
Solid plate 5 simultaneously maintains to pull open state, is also beneficial to bar knife 12 and easily chops disconnected locking line 10.Drawstring 18 is by high strength steel wire material system
Into bar knife 12, movable plate 13, barrier plate 15, supporting rod 16 are made by high-strength stainless steel.The locking spring 7, flat spring
14 are made of high-carbon alloy steel, to keep high resiliency and high intensity.
During elevator normal operation, locking board 5 makes locking pin 6 away from anti-fall plate 8 by 10 pull-up of locking line, while the bullet that locks
Spring 7 is in extended state, and drawstring 18 overcomes 14 pulling force pull-up of flat spring movable plate 13, drawstring 18 and is fixed on barrier plate 15
On the steel wire rope 4 of side, while flat spring 14 is in extended state.Steel wire rope 4 above the bearing of drawstring 18 and steel wire rope 4
Fracture, when making the tenesmus of carriage 1, bar knife 12 is under itself and the collective effect of 14 pulling force of 13 gravity of movable plate and flat spring, quickly
Cut-out locking line 10, then, locking board 5 rotates down under 7 pulling force effect of spring that locks along hinged place, is caught in locking pin 6
In locking groove 9, so as to prevent the tenesmus of carriage 1；Steel wire rope 4 below bearing of the drawstring 18 with steel wire rope 4 is broken, and is made
When carriage 1 drops, steel wire rope 4, drawstring 18 haul mobile bar and are moved up along supporting rod 16 together, are hindered until being blocked plate 15
Gear, that is to say, that barrier plate 15, support plate, movable plate 13, drawstring 18, steel wire rope 4 prevent the tenesmus of carriage 1 jointly.So
Anti-fall device 20 slow down falling for carriage 1 well.
In a kind of elevator with anti-fall device 20, preferably described anti-fall device 20 is equipped with more than two pairs.So
When each pair anti-fall device 20 is different in the bearing on steel wire rope 4, then when the steel wire rope 4 above the bearing of the top breaks,
All locking pins 6, which are caught in locking groove 9, at this time subtracts pendant；Steel wire rope 4 between adjacent bearing is disconnected, then has locking to sell at the same time
6 are caught in locking groove 9 and subtract pendant and barrier plate 15, support plate, movable plate 13, drawstring 18, steel wire rope 4 subtract pendant jointly；In bottom
Bearing below steel wire rope 4 it is disconnected, then all barrier plates 15, support plate, movable plate 13, drawstring 18, steel wire rope 4 subtract jointly
Pendant.
In a kind of elevator with anti-fall device 20, the preferably drawing of more than two pairs of the anti-fall device 20
Rope 18 is each attached to the same place of the steel wire rope 4.Can so be multiplied anti-fall device 20 subtracts pendant effect.
The foregoing is merely the preferable embodiment of the utility model, is not to limit the utility model, it is all
Within the spirit and principles of the utility model, any modification, equivalent replacement, improvement and so on, it is new to should be included in this practicality
Within the protection domain of type.
