Description of the invention (1) Technical scope The present invention relates to a lift system, and in particular, the lift system requires less installation and operation space than a traditional lift system by adopting a combined structure. Embedded _ drive system. BACKGROUND OF THE INVENTION Known elevator systems basically restrict all elevator components to the aisle or main engine room. The aisle is a long vertical column with a rectangular base conveyed by the elevator car. Inside the aisle, among other things, a carriage rail is placed, which is generally a pair of roughly parallel tracks, which is fixed on the opposite wall near the middle of each wall surface and is roughly the same length as the passage. A balance clock 'with a pair of guide rails is adjacent to the third wall surface. Additional components are built into the aisle, including terminal ground switches, rope and sheave configurations, and shock absorbers for balance bells and cars. What matters is the position and orientation of the elevator components, which should be accurate before and at the time. The inner wall of the aisle must be properly sized and aligned, and the physical interface between the aisle wall and the elevator components must be able to withstand different loads during use. Of particular importance is that the guide rails for carriage travel have been properly positioned and reliably maintained. For ride quality and safety, the guide rails need to be accurately vertical, equilateral, and spaced to avoid swaying, vibration, and collisions. The rail is basically a steel T-section with a length of 16 feet. The position of the guide rails in the aisle affects the position of the lifting host, the governor, and the overhead (host room) equipment. The main engine room is basically directly above the aisle. The main engine room contains a built-in main engine and a speed controller, a cabin controller, a positioning device, a motor power generating unit, and a maintenance power-off switch. -4- ^ 〆 This paper size applies Chinese National Standard (CNS) A4 specifications (210X297 mm) (please read 'Notes on the back side to fill in this page first') Pack.

The assembly of a standard traction elevator system will Consumption and complexity. One of the goals of the present invention is to provide an improved elevator system that optimizes the use of space by using one or more multi-functional components, which functions as a balance clock that drives the host and the system. And a support, which eliminates the need for a main room and other space-consuming components. Another goal is to provide an improved elevator system 'which achieves the best efficiency in construction and materials through various methods, including such as A counterweight device is provided that stores potential as an integral part of the lifting configuration, which reduces the torque required to move the elevator car. The present invention achieves the foregoing and other objectives by employing an innovative drive host and the configuration of components that move within the balance weight and move with it. In one example, a balance weight drive assembly includes a motor and a drive pulley , Its size can maintain a narrow shape, at the same time with a lift car suspension and movement. The balance weight drive assembly is connected to the lift car temple through one or more suspension ropes. It is best to have a toothed traction rope, It is suitable for contacting the driving pulley while being fixed vertically in the channel to form the path of the balance weight driving assembly. The traction rope does not have to be a toothed rope, and it can use a traditional rope or a flat rope or a strap. ,, flat ropes, and "flat ropes", ropes or ropes with an aspect ratio 値 greater than 1, where the aspect ratio is the ratio of the width or thickness of the rope or rope. When torque is applied to the drive pulley, Make the balance hammer drive assembly move up and down in the channel. In addition, the steering wheel, guide the rope rope around the drive pulley, and get enough surface contact area and Paper & size applies to Chinese National Standard (CNS) A4 specification (2 丨 0'〆297mm) Please read the back · Note page binding 479050 5. Invention description (3) Total traction. Due to the use of flat ropes, The small outer diameter can be enough for traction, thus saving life n bb between the two shoulder shoulder workshops. The optional use of a flat loop-shaped rope can further enhance the traction. 7 In another f example of the present invention, _4 is included Modular motor arrangement with driving motor fixed on a balance clock body. Each motor has a sheave with one of two fixed ropes attached to a channel top plate, and at the same time by a spring or tension weight The force is at the other end. The motor and the sheave are best placed on the balance clock body (four corners. The motor and the sheave are arranged in proportion to reduce the pure thickness, and at the same time, they are separated due to the need for fixing and operation. . The rope surrounds the upper sheave i path and provides an effective wrap of 36 ° based on high traction. Duplex drive sheaves (used to allow for a large total traction area with small outer rear sheaves and small motors, thus saving space. Another advantage of using the complex drive sheaves and corresponding motors is in the event of a motor failure, As long as other motors have sufficient power, the operation of the elevator system can be continued. Because the suspension rope is separated from a traction rope, they can individually optimize their specific functions without considering other performance characteristics. For example, tension In terms of failure, the suspension rope is the most perfect, because it does not need to provide a traction medium. In addition, for traction, the traction rope is the most perfect and requires only limited consideration of tension failure, because the maximum tension is easily caused by the carriage and The quality difference between the counterweights. In addition, the use of a traction rope can reduce the size of the motor, which can use a round-shaped motor instead of a planar motor.

The traditional version of the description of the invention (5). A strap tensioning device (48) is shown in the outline, and may also be a conventional type such as a spring (not shown). The motor (3 2) can be an electric motor, which can supply power and control signals through electric power and a control cable (50) as shown in the figure, so that the cable can be moved with the balance weight driving assembly (2 6). . 1 A rope, rope group or suspension rope (5 2), as shown in the figure, simultaneously suspend the elevator car (12) and the counterweight drive assembly (26). The first end point (5 4) of the suspension rope (5 2) is fixed to an overhead static object, such as a beam (56) on the ceiling of the aisle. The first idler (58) fixed to the counterweight drive assembly (26) contacts the suspension rope (52). The second idler pulley (60) fixed on the overhead beam (56) contacts the suspension rope (52). The third and fourth idler wheels (6 2, 6 4) are fixed to the bottom of the elevator car (12), and they also contact the rope (52). The third and fourth idler wheels (62, 64) need not be placed on the bottom of the elevator car (12), and may be replaced by, for example, one or more idler wheels placed above the car. The second end (64) of the suspension rope (52) is fixed on the channel (not shown), and its height will be sufficient to allow the elevator car (丨 2) and the counterweight drive assembly (26) as described below. Expected vertical movement. In the printing operation of the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, when the motor (26) is excited, the torque is transferred to the toothed belt (42) via the toothed drive pulley (32), so that the balance hammer drive assembly (26) Will move along and relative to the toothed belt (42). The counterweight drive assembly (26) will selectively move up and down based on the direction of rotation of the toothed drive pulley (36). When the counterweight drive assembly (26) moves downward along the toothed rope belt (42), the first idler wheel (58) moves downwards accordingly, so the length of the rope belt between the first and second idler wheels is lengthened. . Result: The length of the available rope (52) of the mth (6G) is extended, and the paper size is applied to the Chinese national standard (----- 479050 A7 B7. V. Description of the invention (6 is proportionally shortened, which promotes the elevator car (1 2) Lift up on the third and fourth idler wheels (62, 64). Similarly, the elevator car (12) descends when the counterweight drive assembly (26) is driven upward. From the foregoing description of the first example It can be seen that the present invention does not require a main engine room, requires less total material, and allows the use of smaller outer diameter driving wheels (36) and idler wheels (58, 60, 62, 64), because traction is only associated with toothed The arrangement of the pulleys is related. When the host or drive assembly (26) is used for calibration, it can be entered from the bottom of the passage or through the window or port of the elevator car (12). The design of the present invention eliminates the need to move from the motor (32) to the car (12) The vibration and voice caused by the body of the building. The toothed belt (42) and suspension rope (5 2) can naturally reduce the vibration. The balance hammer drive assembly (2 6) can be pre-assembled and pre-tested To save installation time and increase reliability. Toothed belt (42) and drive pulley (36) can be used Eliminates slippage and provides precise positioning. Since traction has nothing to do with weight, a light weight car (12) can be used, thus allowing the use of a smaller and more efficient motor (32). Referring now to Figures 5-6, the present invention The second example illustrates a self-lifting balance clock drive assembly (100). The balance weight drive assembly (100) can be equipped with a rope (52) and an idler (58, 60, 62) according to Figures 1-4. , 64) arranged for use, or connect the assembly (100) with a lift car (丨 2) in a similar manner. In the case of the first example, the movement of the lift car (12) will be driven by the balance weight It is related to the movement of (100). The balance weight drive assembly (100) in the second example includes a set of four electric motors (104, 106, 108, 11) 〇) of the body (102). Each motor (104-110) is equipped with a corresponding drive sheave (112, 9- This paper size applies to China National Standard (CNS) eight 4 ^ grid (210 × 297 mm), please Note for the back M Binding Printed by the Central Consumer Bureau of the Ministry of Economic Affairs Consumer Cooperatives 479050 A7 B7 Economy Printed by the Consumers' Cooperative of the Ministry of Standards of the People's Republic of China (5) Invention Description (7, 114, 116, 118). A pair of fixed ropes (120, 122) are attached to the overhead structure (not shown) in the aisle (not shown) ), Which is fixed or stretched at the bottom by a conventional device (not shown). As shown in the special display of the second rope (122) in FIG. 6, each rope (120, 122) extends downward to contact and wrap A lower driving sheave (118) bottom, extends upward to contact and wrap an upper driving sheave (114), and then extends downward again to be stressed or fixed. The traction between the ropes (120, 122) and the sheaves-118) is controlled by adjusting the tension of each individual rope (120, 122). It is preferable that the ropes (12, 122) are flat ropes' because they can wrap around the smaller outer diameter sheaves but still provide sufficient traction. Then, it can reduce the outer thickness of the assembly (100). In the case of the first example, traction has nothing to do with weight, so a light lift car (12) can be used. In the second example, each drive sheave (112-118) is contacted by one of the ropes (120, 122) at about 180 degrees, so the total effective wrapping angle of each side is about 360 degrees. The total wrapping angle is decisive for the total traction. It is conceivable to change the second example by only driving two of the four motors, or by providing a motor equipped with a transmission element to drive all four sheaves. It is also conceivable to provide only one rope instead of two. It can be understood from the foregoing second example that the stationary motor on a counterweight drive assembly will remove vibration from the carriage (12). The setting of the drive sheave (112-118) can facilitate the installation and maintenance of the sheave. Using smaller motors (104-110) provides cost savings. Although preferred examples have been described herein, it should be recognized that changes to these examples can be made without departing from the scope of the patent application.
