SU10229A1 - Adaptation to lifts with two parallel moving cabs, to achieve a smoother stopping of the cab in its upper final position and more rapid reporting to it of the appropriate speed when starting to descend - Google Patents

Description

The proposed adaptation to a two-cabin lift aims to soften the push, after reaching the top position of the cabs, and inform it of the initial acceleration at the first moment of descent / for which it uses a buffer spring and additional load in the form of lifting shields.

In the drawing, FIG. I is a vertical sectional view of a lift with a proposed fixture; FIG. 2 is a horizontal section along line A, B of FIG. 1. I

In the upper part of the shaft, cabins are fitted with shields 4, which are movable in guide slots, which can simultaneously replace the grill or railing on the open side of the shaft. The boards are raised with the help of protruding in the upper part of the cabin on both sides of the corners 2, resting in the corresponding corners 3 of the boards 4, and abrupt softening of the impact upon reaching the cabin

the upper position is achieved by using buffer springs b against which raised shields b.

Thus, a considerable part of the energy that the cabin possesses is expended on overcoming the weight of the shield and the spring elasticity, which makes the stopping smooth.

When lowering, in the case of application of the proposed device, it is possible to somewhat reduce the difference in weight between the two moving cabs, so that the initial acceleration will be obtained not by the difference abin in weight, but due to the impulse that is reported by the release springs and the weight of the sliding shields. .

The subject of the patent.
