Description
Elevator Driving Mechanism with Multiple Motor
TECHNICAL FIELD
The invention relates to a driving mechanism which enables to increase the capacity of carrying load in elevators used to carry load or people by multiple driving members, without changing the size of the elevator. STATE OF THE ART
Elevators enable to carry people or loads from one place to another in a vertical direction. By means of elevators, people can reach the desired upper floors in skyscrapers and tall buildings, which they cannot reach by spending physical energy normally. Elevators in the present day are electrical or hydraulic. Buildings with five or less floors, where elevators are rather slow, prefer hydraulic type, while the buildings with more than five floors generally use electrical elevators. Without doubt, elevators have a big contribution in the construction of tall buildings and structures. Materials and goods with high weight can be carried vertically by means of load elevators. As the weight of the goods to be carried increases, the sizes of elevators increase too. This situation causes unnecessary space occupation and increases elevator costs. At this point, the driving mechanism of elevators is very important and many researches are carried out in this subject when the importance of elevators in human life and their development with technology are considered.
In the driving mechanisms used in elevators in the state of the art, an increase is seen in the KW value of the driving member as a result of the increase in the load coming to the elevator motor pulley. The increase in the driving member value affects the costs exponentially after a certain value.
Moreover, as the statement load increases, the pulley pressure rises and it becomes necessary to increase surface. For the same reason, it is necessary to increase the pulley diameters to enable holding capability in large statement loads. In order to get above a certain load, it is necessary to get to DC motor practices and this is a choice which increases costs. Moreover, hydraulic systems are used in the state of the art. Hydraulic systems enable very limited solutions as for speed and navigation distance. Also, usage of oil in large amounts is another problem due to the diameters of pistons used.
Another patent research of the state of the art is disclosed in the patent application no 2014/1 1385. In the abstract of this application; this invention relates to an elevator driving motor which enables to drive the elevators, having direct drive, asynchronized motor, flat stripe and steel cord without gear.
Another patent research for the state of the art is disclosed in patent application no. 2016/17513. In the abstract of this application, the invention relates to an elevator system including a drive, cabin and an opposite weight, wherein characterized in that the driving module and/or diverting module are equipped with hangers for fixing a carrier vehicle connection, wherein the drive is equipped with a drive disk and a diversion module and at least one motor to operate this driving disk, the motor and driving disk are mounted by being assembled in as a driving module.
Another patent research for the state of the art is disclosed in patent application no. 1998/00529. In the abstract of this application, the whole driving system, which comprises an electrical motor, a hydraulic pump, an oil tank, valves and a command part is fitted in a cabin, at a hydraulic elevator installation without an motor room. This cabin can be mounted at a desired place where there is a direct connection with the elevator shaft, for example near the elevator shaft door or a place with easy access, preferably close to
the traffic ways, to working areas and even corridors. By means of double sound isolation, which is the isolation of the cabin and the oil tank including the electrical motor and hydraulic pump, the noise of the driving system is suppressed at a degree to make placing the cabin at any place without disturbing the environment.
As a result, there are improvements in driving mechanisms, therefore there is a need for new structures which will remove the abovementioned disadvantages and bring solution to the existing systems.
OBJECTIVE OF THE INVENTION
The present invention relates to a driving mechanism which meets the abovementioned requirements, removes all the disadvantages and brings along some additional advantages.
The main objective of the invention is to provide an ergonomic product requiring little labor and maintenance, by using multiple driving member in carrying high statement loads.
An objective of the invention is to increase the driving capability of the elevator and provide a safer navigation by using multiple driving member.
Another objective of the invention is to carry high statement loads to higher floors in a short time.
A further objective of the invention is to increase the rope life and prevent accidents and problems stemming from ropes, by decreasing the pressures on the pulleys.
Still another objective of the invention is to improve the sensitivity and driving while moving by enabling the multiple driving members operate synchronically by means of electronic systems and software. Structural characteristics and all the advantages of the invention will be understood more clearly by the figures and the detailed description which is written by reference to these figures given below. Therefore, assessment should be made in consideration of these figures and the detailed description.

DETAILED DESCRIPTION OF THE INVENTION
This detailed description discloses the preferred embodiments of the inventive driving mechanism (100) for a better understanding of the subject without any limiting effects.
The present invention is a driving mechanism (100) which increases the elevator (1000) load carrying capacity without changing the elevator (1000) sizes, having a main driving member (10) wherein the necessary power is generated in elevators (1000) enabling to carry people or loads by means of elevator cabin, a rope (12) which transforms the power taken to the vertical movement by being corresponded to the said main driving member (10), and a transmitting member (40) which transmits the force coming from the rope (12) to the elevator cabin for downward-upward movement; characterized by auxiliary driving member (1 1 ) which increases the load carrying capacity of the elevator (1000) by operating synchronically with the main driving member (10) and on which the rope (12) is fitted, a transponder member (20) which enables the said auxiliary driving member (1 1 ) and the main driving member (10) in harmony, synchronically and is located therebetween, control unit (50) which generates the necessary energy and enables to command the elevator (1000), signal generator (70) which determines the rotation speed and rotation numbers of the driving member (10) and the auxiliary driving member
(1 1 ) and convert this information into signal, and a power driver (60) which enables the main driving member (10) and the auxiliary driving member (1 1 ) to operate synchronically and have the same rotation number by the information it obtains from the signal generator (70).
In the present day, high statement loads are applied to load elevators (1000) in particular. For the elevator (1000) to balance, carry this force, it is necessary to increase the sizes of parts such as elevator cabin, rope (12) width, transponder member (20) together with the capacity of the main driving member (10). This causes both cost and unnecessary occupation of space. This can be overcome in a more efficient, low cost way by using the auxiliary driving member (1 1 ) which increases the load carrying capacity of the elevator (1000) by operating synchronically with the main driving member (10) in the inventive driving mechanism (100) and on the surface of which the rope (12) is fitted. Preferably at least one auxiliary driving member (1 1 ) is used in the driving mechanism (100). Thus, the elevator (1000) will be able to carry high statement loads. Figure 1 illustrates the general perspective view of the inventive driving mechanism (100). The member which enables the said auxiliary driving member (1 1 ) and the main driving member (10) harmonically and synchronically and is located therebetween is the transponder member (20). The transponder member (20) is made of a pulley preferably in a cylindrical shape. The transponder member (20) performs the act mentioned above by means of the rope (12). The rope (12) helps operating synchronically by fitting on the surface of the auxiliary driving member (1 1 ), the main driving member (10) and the transponder member (20). Depending on the elevator (1000) operation conditions and driving transmitting preferences, the rope (12) can be used in the system by double winding by removing the transponder member (20) (see Figure 3). Figure 5 shows the general perspective view of the inventive driving mechanism (100) when it is mounted to the elevator (1000). A control unit (50) is provided which generates the energy needed in the elevator (1000)
and enables to command the elevator (1000). It preferably has an electronic system. Effective operation of the driving mechanism (100) depends on the synchronic operation of the main driving member (10) and the auxiliary driving member (1 1 ). This dependency is directly connected with the rotation numbers. In order to even out the rotation numbers, it is necessary to determine and measure the rotation speeds. Signal generator (70) determines the rotation speeds, rotation numbers of the main driving member (10) and the auxiliary driving member (1 1 ) and converts this information into a signal. Signal generator (70) transmits this information to the power driver (60). There are at least two power drivers (60) in the driving mechanism (100), in such a way to be identified and connected to the main driving member (10) and the auxiliary driving member (1 1 ) separately. The power driver (60) evaluating the signals coming from the signal generator (70) enables the driving members (3-1 1 ) synchronically in the same rotation numbers. For the elevator (1000) to operate efficiently, safely and controllably, a control unit (50), a power driver (60) and signal generator (70) preferably having an electronic system is used. The abovementioned balancing member (30) is the opposite weight pulleys, and the transmitting member (40) is the cabin pulleys.
Moreover, for the elevator (1000) to operate controllably, there is a balancing member (30) that moves the balance weight opposite the elevator cabin weight upward and downward and on which the rope (12) is located.
