Description

1 TARIFF RECTANGULAR CROSS-SECTION BALANCE CHAIN ​​FOR ELEVATORS Technical Area This invention reduces the load created by the carrier ropes in elevator systems by 5 to reduce its effect on the drive machine during starts and stops It relates to a balancing system. Specifically, it balances the rope loads of the motor. a balance chain aimed at minimizing strain and energy consumption It is related to its structure. State of the Art Balance chains are a commonly used system in elevator applications. From the weight of load-bearing elements such as suspension ropes and flexible cables The resulting imbalances are undesirable, especially on the drive roller. This causes imbalances. To reduce such imbalances, balance 15 Chains are used; thus, the engine and the cab are independent of the cab position. The load distribution on the pulley is fixed. Stabilization systems become standard at travel distances exceeding 30 meters. 20 compliant with standards such as ASME 17.1 and EN 81-1 at rated speeds above 3.5 m / s. Steel wire ropes are preferred. These ropes are fixed to the bottom of the cabin and the well... It is passed through the pulley at the base and connected to the counterweight frame. In these systems... Lower pulleys must be equipped with an anti-rebound device and the necessary safety features. The systems must be put into operation. For speeds below 3.5 m / s, chain-type leveling systems may be preferred. Chain systems are less expensive and do not require a tensioning device. It offers a more practical solution. In addition, the balancing systems are plastic coated. chains, such as chains containing plastic aggregates and cable-integrated chains, are different types. It can be of different types. 30 2 Basic Elements of an Elevator System Drive pulley Balance weight elevator cabin Balancing chain 5 Suspension / Load ropes Flexible cables Safety systems These components are balanced and securely positioned within the elevator shaft. 10 should be positioned accordingly. The rope weight should be equalized with the corresponding balance chain weight. The traction balance of the system is maintained. Flexible cables connect the cabinet and the control panel. It enables data transmission between them. The Function of the Balancing System 15 The dynamic load of the ropes as the cabin moves up or down is a part of the system. is transferred to the side. The balance chain balances this load on the drive machine. It prevents imbalance in pulling force. The weight and length of the rope and chain must match. They must be equivalent. For system safety, at least four suspension ropes are required. It is recommended to use it. 20 In systems without lower pulleys, chains hang freely in the air. It can be exposed to external influences such as current and vibration. Especially bare chains. Problems such as friction-related noise and wear are observed in these systems. Plastic Packed chain systems largely prevent these kinds of problems. 25 Advantages of Plastic-Filled Counterbalance Chains Balanced weight distribution Reducing the risk of wear and noise. Protection of the reel surface. Preventing failures such as cracking and chain skidding 30 3 These types of chains typically consist of a PVC outer sheath, an inner steel cable, and plastic padding. It is structured cylindrically to contain the material. Conventional Balance Chains and Measurement of Turns Coated chains are designed to work with tight turning radius. If 5 If the turning radius is made larger than necessary, the chain will oscillate inside the well. It can hit the equipment. Therefore, the natural turning radius of the chain must be taken into account during assembly. Alternative Balancing Methods 10 Installing static weights leads to a loss of performance. Adding a secondary balance chain – Provides greater stability but increases cost. Using a chain with a large turning radius – More central and balanced mounting. It allows it to be done. Although flexible cables have been used historically, their costly construction and frequent maintenance... It is not the ideal solution due to its requirements. Assembly Details One end of the balance chain is attached to the bottom of the cabin, and the other end to the guide line in the well. It is passed through the pulley and attached to the counterweight frame. Chain assembly 20 It is important to maintain the natural turning radius during installation. Incorrect assembly can damage the cabin. This can negatively affect the balance and system performance. If necessary, maintain a constant balance. The system must be rebalanced by adjusting the weights or using alternative mounting methods. Elevator comfort, safety, and quietness are important for user experience. 25 The noises caused by circular cross-section chains, in particular, can be unsettling for the user. This can create problems. Therefore, balance chain structures that reduce sound and vibration are preferred. This is a primary goal for elevator manufacturers. 4 THE PURPOSE OF THE INVENTION The aim of this invention is to investigate the deformation caused by circular cross-section balance chains. rectangular width to eliminate problems such as bending limitations and noise The aim is to present a sectional balance chain design. Thus, the deformation of the coating material such as plastic and rubber is delayed and 5 A wider bending angle is provided. This invention improves the up-and-down movement of the elevator. the load created by the carrier cable during the elevator's start and stop to minimize the overload it creates in the elevator drive machine It is a part that balances the rope load. Comfort, safety, and low energy consumption of motor power in elevators are 10 Ensuring safety is important. Those who use elevators often experience malfunctions and falls. They get into the elevator with apprehension, fearing an extra noise in the elevator. This makes users uneasy. Therefore, elevators should be very quiet and vibration-free. This research has always been a forward-looking goal for elevator manufacturers. This product, which provides silence and comfort, is the elevator balance chain. Balance 15 The chains help the machine to start without strain during the elevator's initial lift. Therefore, it provides comfort during the start-up process. Nowadays, elevators... The balance chains currently in use have a circular cross-section. Circular chains deform quickly due to their limited bending angles. And the sound is produced by the friction of the metal as it passes through the rollers. 20 The noise is causing anxiety among those using the elevator. The purpose of the invention is to modify the circular shape of the balance chain using plastic or rubber. delay in material deformation over time and bending angle The goal is to ensure its increase. 25 To achieve the invention's purpose, a balance chain with a rectangular cross-section for elevators was developed.
