SU18541A1 - Barrier for lifts - Google Patents

Description

To automatically open and close the access to the elevator shaft, a horizontal barrier is installed in front of the shaft opening in each floor, suspended on ropes wound on wheels, driven by a gear transmission when the rack rail touches the staple mounted on the elevator stand.

In FIG. 1 is a schematic side view of the device; FIG. 2 - the same in the top view.

Horizontal bar-barrier 9 is suspended on cables 8 across the hole in the shaft of the lift. Cables 8 are wound on drums 7, mounted on an axle common to them, carrying a gear rigidly attached to it and a cogwheel b located between the drums, designed to be assembled in a stage, moving with the rack 4, moving in its guides 5 and carrying end facing. in the direction of the shaft, roller 3, and at the opposite end, an emphasis 10, limiting the horizontal movement of rail A. On the outer c: stand cage L is reinforced skiba 2, which has an inclined upper and lower parts a b b and is designed to come PEACE 3 fixed on the end of the rail 41

In the absence of a cage in front of the hole of the shaft, the bar 9 is lowered by the force of its own weight and through the gear wheel moves the rail with roller 3 towards the shaft. When the stand approaches, the clamp 2 by the inclined part a gradually depresses the rail by contact with roller 3, the drums 7 rotate and lift the barrier 9, and along the stand upward the barrier dny is given its own weight due to the gradual rolling of the roller 3 along the inclined part 6 of the bracket 2.

The subject of the patent.

A barrier for lifts, characterized in that for automatic lifting of the barrier bar 9 suspended by flexible couplings 8 to the drums 7, in order to free the passage to the cage, a rack 4 is used, which engages with gear gear 6 fixed on the common axis the drum 7, and provided with a stop 10, limiting the stroke of the rail, and a roller 3, for shifting which and the rail 4, for the purpose of the indicated raising of the bar 9, the bracket 2 attached to the stand 1 of the conventional device.
