Preferably, the elevator falling-proof safety device, wherein the quality of the card-stopping bar is greater than the quality of lance.
Card-stopping bar and lance mass ratio, length ratio and limit spring, maximum speed limit value of the installation site to elevator for limiting brick
All have an impact, needs by precision allotment and repeatedly test, therefore, the debugging of the device should be carried out by professional.
Preferably, the elevator falling-proof safety device, wherein the locking bar material is unimach.
Preferably, the elevator falling-proof safety device, wherein the stop block includes the first stop block and the second card
Stops, the first stop block are weldingly fixed on above the second stop block.
Preferably, the elevator falling-proof safety device, wherein second stop block is foamed aluminium material；Foam
Aluminium has good high-damping shock stability and impact energy absorptivity, and theoretically, the foamed aluminium that porosity is 84% occurs
When 50% modification, it can absorb 2.5MJ/cm3Above energy, when the instantaneous impact when lift car is locked is larger, the
Deformation occurs for two stop blocks, absorbs a large amount of kinetic energy, reduces the instant impact to carriage, reduces the injury to passenger and carriage.
Preferably, the elevator falling-proof safety device, wherein the percussion hammer is externally provided with abrasive rubber layer.Percussion hammer by
It in being frequently in contact with impact head, can be prolonged the service life using abrasive rubber layer, substantially reduce the noise generated when contact,
In addition, in order to reduce frictional dissipation, it should also be in the regular coating lubricating oil in the inclined-plane of percussion hammer and impact head.
The utility model has the advantages that
The elevator falling-proof safety device of the utility model is not necessarily to electric control, gets rid of the dependence to various sensors, when
Elevator runs more than and engages carriage when limiting speed, and structure is simple, easy to maintain, and there is buffering effect in when locking, to passenger and
Damage caused by carriage is small.
