Abstract

The utility model relates to a safe self-controlled braking device for elevators. An active brake block, a fixed leaned plate and a force sending spring are arranged in a shell of the utility model. A guiding mechanism for an elevator track is arranged on the shell and the force sending spring supports the active brake block. The fixed leaned plate and the active brake block is matched with the fixed leaned plate in a slope mode and is fixed in the shell. When the cable of a lifting table is broken, the force sending spring pushes the active brake block upwards automatically to hold the elevator track, and the fixed leaned plate moves down with the lifting table, so the lifting table is braked. The device can stably brake a 1.5 tons lifting table within 50 centimeters from the position where the cable is broken. The utility model has the advantages of simple structure and low cost. The utility model is suitable for being used in transport elevators in construction and indoor elevators for transporting both passenger and goods.

Description

The safety auto-controlled brake apparatus of a kind of elevator

The utility model belongs to a kind of elevator safety brake apparatus.

Be used for the transportation elevator of building operation, the elevator of indoor passenger and freight transportation, because of disconnected Suo Zaocheng personal injury of bay-lift or cargo damage accident, And is not rarely seen.For avoiding this type of accident, adopted the service brake device, when breaking rope, the people adopts service brake at bay-lift, checks bay-lift by transmission device, and it is timely that this device is difficult to stop, poor reliability.

The purpose of this utility model provides a kind of stop timely, the safety auto-controlled brake apparatus of good reliability.

The utility model safety brake apparatus is achieved in that a housing has the activity piece of stopping in it, fixedly lean to plate, send power spring and rubber bowl, the rail-guided mechanism of one elevator is arranged on it, the power spring of sending places rubber bowl, be used for the support movable piece of stopping, the activity piece of stopping has a rough surface And who matches with the elevator trade shape to have an inclined-plane to do the inclined-plane cooperation by slideway with fixedly leaning to plate, stop piece and fixedly lean to the combination of plate of formation activity, fixedly lean to plate and be fixed in housing, housing is fixed on the bay-lift, in addition, also have the rail-guided mechanism of elevator that forms by pulley on the housing, make the elevator track under normal operation, not touch the stop rough surface of piece of activity.When falling when the disconnected rope of bay-lift, the activity piece of stopping reduces the pressure that send the power spring, and the power spring of sending is stopped piece to activity along pushing away on the slideway automatically, make it touch the bay-lift track, fixedly lean to plate and move down, and then make the activity piece of stopping block the bay-lift track, check bay-lift automatically with bay-lift.

What the utility model was stopped is timely, stable, reliability Da ， And and simple in structure.

Below in conjunction with accompanying drawing the utility model is described in further detail.
