Description
Technical Field
The present invention relates to a double-car elevator system in which two elevator systems are installed in one elevator shaft.
Background
At present, elevators are most practical as a system for transporting people in a vertical direction in high-rise buildings. In a common elevator, only one elevator car is arranged in one elevator shaft, along with the development of the society, a plurality of high-rise buildings are provided, the land is limited, the building area is limited, and the elevator shafts can not be built too much, so that the elevator phenomena of the existing high-rise buildings and the like are normal.
Disclosure of Invention
The invention aims to solve the technical problem of providing a double-car elevator system which is convenient to install and control, and the method is suitable for installing newly-built elevators and modifying old elevators, and is simple and easy to implement.
The invention comprises the following contents: the elevator comprises (1) a car A, (2) a car B, (3) a counterweight A, (4) a counterweight B, (5) a traction machine A, (6) a traction machine B, (7) a guide wheel A, (8) a guide wheel B and (9) a mounting surface.
The invention adopts the following technical scheme: two cars and two counterweights are installed in one elevator shaft, the two cars run on the same car track, the two counterweights run on the same counterweight track, two tractors are reasonably installed in a control room or other positions, each car and the corresponding counterweight, the tractor, a guide wheel and other accessories form a group of independent elevator running systems, and each elevator system runs in a set floor interval. The car and the counterweight of the two elevator systems are installed in a staggered mode, the car A (1) is arranged above the car B (2), the counterweight B (4) is arranged above the counterweight A (3), and the traction ratio is 2: 1,1: 1 the speed of the car and the counterweight in the elevator system is equal, and the moving distance at the same time is also equal, so the position of the car is controlled, the position of the counterweight is controlled, the car runs in a set floor interval, and the counterweight also runs in a set interval, so the elevator system is not disordered and does not collide.
When the center distance between the car A (1) and the car B (2) is H in a state 1, the center distance between the counterweight A (3) and the counterweight B (4) is H1, the center distance difference is H-H1-H1, when the car A (1) does not move the car B (2) to move upwards for a distance X in a state 2, the downward running distance of the counterweight B (4) is X, the center distance between the cage A (1) and the cage B (2) is H-X, the center distance between the counterweight A (3) and the counterweight B (4) is H1-X, the center distance difference is H-X- (H1-X) ═ H-H1 ═ H1, in the state 3, when the cage A (1) does not move the cage B (2) for the downward moving distance X, the center distance difference is H + X- (H1 + X) ═ H-H1 ═ H1, therefore, the difference between the center distance of two adjacent counterweights and the center distance of two adjacent cars is a fixed value h1 in any state, and the value h1 is determined in actual installation. The independent operation systems of each elevator system are not interfered with each other, transfer layers are arranged on adjacent floors of the operation of the two cars, the operation of the two elevator systems on the transfer layers is interlocked and controlled, and the transfer layers are one or more.
The invention has the following beneficial effects: the number of elevator shafts is reduced in a building, three-dimensional space resources are fully utilized, the construction cost is saved, the available area of the building is increased, and the land area is saved; the carrying efficiency is increased, and the waiting time of passengers is reduced.

Detailed Description
The technical solutions of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure in the specification; the invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. The present invention will be described in further detail with reference to the accompanying drawings.
As in fig. 1, traction machine sheave linear velocity: linear speed of the car: the counterweight linear velocity is 2: 1: 1, a traction machine pulley is a fixed pulley, a pulley corresponding to a car and a counterweight is a movable pulley, one end of a cable of an elevator A is fixed at a proper position of an installation surface (9), bypasses a pulley at the upper part of the car A (1), bypasses a traction machine A (5), bypasses a guide pulley A (7), and is fixed at a proper position of two groups of pulleys bypassing the counterweight A (3) and the installation surface (9); one end of a cable of the elevator B is fixed at a proper position of the installation surface (9), bypasses a pulley at the upper part of the counterweight B (4), bypasses a traction machine B (6), bypasses a guide pulley B (8), bypasses two groups of pulleys of the cage (2), and the other end of the cable is fixed at a proper position of the installation surface (9); because the number of cables is large, a group of steel structures are arranged below the mounting surface (9), and the guide wheels or rolling wheels are arranged on the steel structures to guide the cables to the correct positions. In actual installation, because the area of the machine room is smaller, two traction machines can not be arranged, one traction machine can be arranged in the machine room, and the other traction machine can be arranged in a hoistway (without the machine room) or other methods.
The AB two-elevator system is a full-floor operation system or an interval operation system, then partial floor operation functions of the AB elevator are respectively closed, an AB elevator operation interval is set, the elevator A operates on the upper layer, the elevator B operates on the lower layer, the elevator A normally operates when the elevator B fails, and the elevator B normally operates when the elevator A fails.
If in a certain hospital in a certain city, have many elevators wherein one to two elevators supply the low floor to use, increase the low floor guest and circulate, and the upper space of this well is idle this moment, if install two elevator systems, just provide an interior elevator for the floor above and use, like this also greatly increased floor guest's turnover above. If the outpatient service center and the sickrooms are in the same building with 20 floors, the elevator A is used for the sickrooms on the 10-20 floors, the elevator B is used in the outpatient service center on the 1-10 floors, and the two elevators are linked at the 11 th floor to transfer passenger flow.
The foregoing embodiments are provided merely to illustrate the principles of the invention and their advantages, rather than to limit the invention, and it will be apparent to those skilled in the art that modifications and variations can be made therein without departing from the spirit and scope of the invention.
