Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
A kind of as shown in Fig. 1 ~ 3, which has, subtracts the elevator of fall device, including square carriage 1, elevator 2, traction electric machine 3,
Steel wire rope 4, for the vertical carriage 1 in the vertical elevator 2, the traction electric machine 3 is fixed on the elevator 2
On outer end face, the traction electric machine 3 draws the carriage 1 by the steel wire rope 4 and moves up and down.
The elevator, which further includes, subtracts fall device, and the fall device that subtracts is arranged in pairs in steel wire rope 4 to be symmetrically axisymmetric
With 1 railway carriage or compartment of carriage door on two adjacent 1 lateral surfaces of carriage, the fall device that subtracts includes square column cylinder 5, barrier plate 6, friction
Plate 7, mobile bar 8, spring 9, drawstring 11, pulley 12, friction lever 13.
The square column cylinder 5 is vertically fixed on 1 lateral surface of carriage, and the mobile bar 8, spring 9 are located at the square column
In cylinder 5.
The vertical section of 8 lateral surface of mobile bar and the vertical section of 5 medial surface of square column cylinder match, and make mobile bar 8
Movement can be stablized in square column cylinder 5.
Described 9 one end of spring is fixed on 1 lateral surface of carriage, 11 one end of 9 other end of spring and the drawstring
It is fixed on one end of the mobile bar 8,8 other end of mobile bar stretches out the square column cylinder 5 and is vertically fixed on the stop
On 6 side of plate, 6 opposite side of barrier plate is fixed together with the friction plate 7, and the friction lever 13 is fixed on described vertically
In elevator 2, for the friction lever 13 positioned at the outside of friction plate 7, friction lever 13 described in 7 face of friction plate, makes movement
During the side movement outwardly of bar 8, friction plate 7 can encounter friction lever 13.The opposite face of the friction plate 7, friction lever 13 is rough surface,
With increasing friction force.
The vertical section area of the barrier plate 6 is more than the vertical section area of 5 medial surface of square column cylinder, thus makes stop
The mobile bar 8 that plate 6 can prevent continues to move towards 1 direction of carriage in square column cylinder 5.
The pulley 12 is fixed on the 1 lateral surface phase of the carriage that the 1 outer end face of carriage is fixed with the square column cylinder 5
At friendship, be conducive to pulley 12 and give full play to steering-effecting.
Open up a rope through hole 10 on the square column cylinder 5, the rope through hole 10 be located at the mobile bar 8 and the carriage 1 it
Between the square column cylinder 5 upper surface on, rope through hole 10 is always positioned at the inner side of mobile bar 8.The drawstring 11 it is another
Restrict through described outside through hole 10 to the square column cylinder 5 one end.
When elevator works normally, the drawstring 11 draws the mobile bar 8 barrier plate 6 is leaned against 5 end of square column cylinder
On face, the drawstring 11 is fixed on through the pulley 12 on the steel wire rope 4 of the top of pulley 12, and symmetrical subtracts pendant dress
The drawstring 11 put 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 11 from drawing partially
Steel wire rope 4 and influence elevator normal operation.Spring 9 is in compressive state at this time, and during so that steel wire rope 4 breaking, spring 9 can be friction
Plate 7 pushes friction lever 13 to.
Elevator works normally, distance and institute of bearing of the drawstring 11 on the steel wire rope 4 to the pulley 12
The difference for stating steel wire rope 4 to the distance of the pulley 12 is more than the friction plate 7 to the distance of the friction lever 13, so that described
When drawstring 11 does not draw the mobile bar 8, the spring 9 can be such that the friction plate 7 withstands on the friction lever 13, in order to keep rubbing
Wiping subtracts pendant, and spring 9 should be compressive state.When i.e. steel wire rope 4 breaks above bearing, spring 9 makes mobile bar 8 move laterally,
I.e. friction plate 7 is moved to 13 direction of friction lever, because the symmetrical drawstring 11 for subtracting fall device is fixed at one, when two drawstrings 11 pass through
When two pulleys 12 are drawn as being located at same straight line, between two pulleys 12 11 length of drawstring be exactly when steel wire rope 4 is not disconnected pulley 12 to
Twice of 4 distance of steel wire rope, at this time, the distance that friction plate 7 is moved to friction lever 13 are above-mentioned difference, so only guaranteed difference
To the distance of friction lever 13, friction plate 7, friction lever 13 could rub carriage 1 to be subtracted friction plate 7 when value is more than elevator normal work
Pendant.
During elevator normal operation, barrier plate 6 is leaned against on 5 end face of square column cylinder, and friction plate 7 will not touch friction lever 13, i.e., not
Friction can be produced and subtract pendant effect；When steel wire rope 4 above the junction of drawstring 11 and steel wire rope 4 is broken, spring 9 makes friction plate
As soon as 7 pairs of friction levers 13 apply a big pressure, such friction lever 13 is applied with a big upward friction to friction plate 7
Power, makes 1 lapse rate of carriage substantially slow down so as to generate and subtract pendant effect；Below the junction of drawstring 11 and steel wire rope 4
When steel wire rope 4 is broken, at this time, steel wire rope 4, drawstring 11, mobile bar 8 still make barrier plate 6 lean against on 5 end face of square column cylinder, so
The tenesmus of carriage 1 is just prevented, so as to prevent unexpected generation well.
In described having subtracts the elevator of fall device, in two carriage 1 lateral surfaces adjacent with 1 railway carriage or compartment of carriage door
On be preferably provided with more than two pairs and subtract fall device.So when each pair, to subtract bearing of the fall device on steel wire rope 4 different, then only most
Steel wire rope 4 above the bearing of top is disconnected, and carriage 1 can just drop, and all friction plates 7, the friction of friction lever 13 at this time subtracts pendant；
Steel wire rope 4 between adjacent bearing is disconnected, then have at the same time friction plate 7, the friction of friction lever 13 subtract pendant and steel wire rope 4, drawstring 11,
Mobile bar 8, barrier plate 6, which coordinate, subtracts pendant；Steel wire rope 4 below the bearing of bottom is disconnected, then all steel wire ropes 4, drawstring
11st, mobile bar 8, barrier plate 6, which coordinate, subtracts pendant.Certainly also can whole drawstrings 11 fix at one, with the friction plate 7 that is multiplied, friction
The friction of bar 13 subtracts pendant or steel wire rope 4, drawstring 11, mobile bar 8, barrier plate 6 coordinate the effect for subtracting pendant.
In the present embodiment, preferably described friction plate 7 is made of the plastics of great friction coefficient, preferably described friction lever 13 by
Fiberglass is made, and preferably described drawstring 11 is made of high strength steel wire material, preferably described square column cylinder 5, barrier plate 6, mobile bar
8th, pulley 12 is made by high-strength stainless steel, and preferably described spring 9 is made of high-carbon alloy steel, and so subtracting fall device can be more preferable
Ground, which is realized, 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.
