Problems solved by technology

However, due to the limitation of the use occasion itself, it is not convenient to arrange the safety door on the side of the landing, so when designing a double elevator, it is necessary to configure a side wall escape door
[0005] Since the double elevator has special requirements for civil engineering, if two traditional single elevators are used as the rescue ladder for the two cars of the double elevator, the layout will be inconvenient

Embodiment 1

[0037] Double-connected elevator system, each group of double-connected elevators includes two cars that are connected to each other and move simultaneously and in opposite directions; N groups of double-connected elevators are installed in the hoistway, and N is an integer greater than 1;

[0038] like figure 1 As shown, when the two cars 10 of the same group of double elevators are set up:

[0039] like figure 2 As shown, the N groups of double elevators are successively arranged adjacently in the hoistway 1;

[0040] Car doors 11 are established on the front side walls of the two cars 10 of the frontmost group of double elevators, and escape doors 12 are established on the rear side walls;

[0041] Car doors 11 are established on the rear side walls of the two cars 10 of the last group of double elevators, and escape doors 12 are established on the front side walls;

[0042] A car door 11 is established on the left side wall of the left car 10 of each group of double el...

Embodiment 2

[0056] Based on the double elevator system of embodiment one, such as Figure 5 As shown, at least one group of double elevators is arranged as a double elevator with a suspension ratio of 1:1, the suspension rope 3 bypasses the top of the guide pulley 5, and the two ends of the suspension rope 3 are respectively connected to the tops of the two cars 10 of the group of double elevators. .

[0057] A double elevator with a suspension ratio of 1:1, including two cars 10 installed in the hoistway running simultaneously and in opposite directions. The upper part is pulled and operated by the elevator host 4 through the suspension rope 3, and the guide pulley 5 is used to adjust the distance in the horizontal direction between the two cars 10.

Embodiment 3

[0059] Based on the double elevator system of embodiment one, such as Figure 6 As shown, at least one group of double elevators is arranged as a double elevator with a suspension ratio of 2:1. The tops of the two cars 10 of this group of double elevators are respectively fixed with a return sheave 6, and two ropes are arranged on the top of the machine room or the hoistway. The head termination device 7, the suspension rope 3 walks around the top of the guide pulley 5 and the bottom ends of the two return rope wheels 6, and the two ends of the suspension rope 3 are respectively connected to the two rope head termination devices 7.

[0060] For a double elevator with a suspension ratio of 2:1, compared with a double elevator with a suspension ratio of 1:1, the car is equipped with return rope pulleys 6 at 10 places, and a rope end terminal device 7 needs to be installed on the top of the machine room or shaft for The end of suspension rope 3 is installed.

Abstract

The invention discloses a double-linkage-car elevator system. A plurality of groups of double-linkage-car elevators are sequentially arranged in a hoistway, escaping doors are arranged on specific side walls of cars of the groups of double-linkage-car elevators, the cars of the adjacent groups of double-linkage-car elevators can be connected in a butt-joint mode through the escaping doors, the elevators are rescue elevators for one another, butt-joint rescue between corresponding cars of the adjacent groups of double-linkage-car elevators can be achieved, civil engineering arrangement is simple, and system maintenance is convenient. Since four cars on the two sides of the adjacent groups of double-linkage-car elevators are connected in a butt-joint mode at the same time, the rescue efficiency is greatly improved. The invention further discloses a failure rescue method for the double-linkage-car elevator system.

Description

technical field [0001] The invention relates to elevator technology, in particular to a double elevator system and a fault rescue method thereof. Background technique [0002] A double elevator refers to an elevator system consisting of two cars connected to each other by a traction rope, etc., moving simultaneously and in opposite directions. [0003] At present, the patents on double elevators mainly focus on car leveling adjustment and elevator layout. Due to the difference in the elongation of the suspension rope due to the different loads of the cars, it needs to be adjusted to achieve accurate leveling of the two linked cars. In the "elevator device" with the Chinese patent announcement number CN1628066A, various adjustment methods are proposed, such as the length adjustment of the suspension rope on the upper part of the car, the relative position adjustment of the car and the car frame, etc. Precise leveling of compartments. The two cars of the double elevator are...
