Description

(5) LIFT LIFT

one

The invention relates to a lifting and transport equipment, in particular to the lift engineering.

A lift elevator is known, comprising cabs mounted on guide pits, equipped with doors, and an actuator located in the upper part of the building and connected to the traction sheave i.

The disadvantages of the well-known elevator, as well as of all the periodic elevators, are the long waiting times of the called cab and the lack of safety.

The purpose of the invention is to improve the operating conditions.

The goal is achieved by the fact that the cabs are made of several sections, each of which is equipped with a frame, the number of sections included in each cabin is one less than the height of the building, and the sections themselves are installed with

offset relative to each other on one floor.

In addition, the lift is equipped with a device for balancing the cabs.

In this case, the device for balancing cabs can be made in the form of a traction sheave mounted in the upper part of the shaft. IQ In addition, the device for balancing the cabs can be made in the form of a two-arm lever hinged under the cabins on the wall of the shaft and connected J5 sharuirno by means of rods with the frame of the cab.

In addition, the mine can be equipped with partitions mounted between the cabins on the lower and upper floors.

Figure 1 shows a fragment of a building scheme with an elevator lift; figure 2 - section aa in fig.k

The elevator includes a rail 1 with guides 2 for two adjacent multi-storey cabins 3. Cab 3 includes a multi-bay frame supporting frame k in which floor-mounted compartments 5 are mounted, equipped with doors 6 for communication with platforms 7 of the building and doors 8 for transition into the adjacent cab 3.

The frames of the compartment 5 are suspended on a common rope 9, enveloping the traction driving pulley 10 of the drive, and supported through the hinge rods of 1 G on the lever 12. The stops 13 are installed at the bottom of charge 1 in fixation of the extreme positions of the shaft 1 between the cabins 3, blind partitions 14 are mounted. The supports of cabs 3 on the lever 12 increase the safety of the elevator installation and eliminate the need to install safety devices.

The elevator drive 15 may be located in the upper part of the building and be connected to the traction sheave 10,

The actuator 15 can also be installed in the lower part of the building and is connected to the lever 12. In this case, the suspension of the cab 3 is optional.

The maximum waiting time of the elevator is

where the travel time of the cab 3

on one floor;

t is the total time of exit and entry of passengers.

The proposed elevator installation can be used most efficiently in buildings of relatively low number of floors (3-6) with constant communications between floors (for example, commercial or administrative buildings).

Due to the small size of the shaft 1 in terms of, the proposed elevator installation can be constructed with escalator installations. In addition, it provides a reduction in waiting time, 5.

Claims (3)
