It sets.
Another purpose of the utility model is to provide a kind of cargo lift anti-falling safe for building for having buffering effect
Device.
In order to solve the above-mentioned technical problem, the utility model discloses a kind of cargo lift anti-falling safes for building to fill
It sets, the guide rail including carriage two sides and the locking wheel being fixed on carriage two sides, the locking wheel is herringbone bear or spur gear,
Unusual fluctuation from horizontal direction can be eliminated using herringbone bear, keep elevator operation more steady, and locking wheel can be effectively prevent to exist
It is detached from when being locked with main guide rail.The guide rail includes the main guide rail that is oppositely arranged and locking rail, the main guide rail be equipped with
The gear teeth that locking wheel matches, the locking rail are equipped with locking surface, and locking surface is equipped with several cards to match with locking wheel
Limited step；Ground is fixed in the top axis connection of the main guide rail and locking rail, main guide rail bottom, and the bottom for engaging rail, which is equipped with, to push
Device；
When elevator works normally, the distance between main guide rail and locking rail working face are greater than the diameter of locking wheel, locking
Wheel moves up and down along main guide rail；When elevator occurs abnormal, pushing meanss are triggered, push locking rail close to main guide rail, by card
Only wheel is locked；
The main guide rail is equipped with velocity sensor, and the rotation axis of the locking wheel is equipped with speed probe；The card
It only takes turns and the fixed link axis connection in carriage；When abnormal conditions occur, pushing meanss start immediately, need to will only engage rail to master
Guide rail direction pushes the distance of very little, contacts locking rail with locking wheel, locking wheel can be made to no longer rotate, to play locking
The effect of carriage.
Preferably, the cargo lift falling-proof safety device for building, wherein the locking wheel is that carriage two sides are each
One or vertical arrangement it is multiple.Locking wheel is more, and the load of single locking wheel is smaller, can simultaneously participate in the locking of locking effect
Piece is also more, and locking effect is more secure.
Preferably, the cargo lift falling-proof safety device for building, wherein each locking plate shape and card
Only wheel matches, and hooking sheet and locking wheel is made to have reasonable contact area.
Preferably, the cargo lift falling-proof safety device for building, wherein when velocity sensor detects elevator
When speed is higher than setting value, propulsion device is triggered.
Preferably, the cargo lift falling-proof safety device for building, wherein when speed probe detects locking
When wheel speed is higher than setting value, propulsion device is triggered.
Preferably, the cargo lift falling-proof safety device for building, wherein the hooking sheet is foamed aluminum materials
Material.Foamed aluminium has good high-damping shock stability and impact energy absorptivity, theoretically, the foamed aluminium that porosity is 84%
When 50% modification occurs, it can absorb 2.5MJ/cm3Above energy, the instantaneous impact when lift car is locked are larger
When, deformation occurs or even fractures for hooking sheet, causes locking wheel to continue to move according to inertia along main guide rail, then encounters next locking
Piece, during deformation occurs or even fractures for hooking sheet, hooking sheet absorbs a large amount of kinetic energy, is encountering next hooking sheet
When, kinetic energy continues to decay, and so on, until lift car stop motion.
Preferably, the cargo lift falling-proof safety device for building, wherein the hooking sheet is detachable and interchangeable,
It when hooking sheet is damaged or is corroded, should replace in time, guarantee its effect.
Preferably, the cargo lift falling-proof safety device for building, wherein the main guide rail is slot type rail, can
It effectively prevent locking wheel to be detached from when being locked with main guide rail.
Preferably, the cargo lift falling-proof safety device for building, wherein the gear teeth are located at the slot of main guide rail
Bottom.
The utility model has the advantages that
The cargo lift falling-proof safety device for building of the utility model realizes electricity by the way of locking locking wheel
The anti-fall effect of ladder, has the characteristics that big load, anti-temporary impact, buffering energy-absorbing can be born, and it is biggish to be suitable for physical burden
Cargo lift for building.
