The most common construction elevator model in China now is the SC gear rack type, dual-purpose construction elevator for both people and goods, of which more than 90% are 12 ton class.
Generally, the contactor relay control method is used for elevators, which involves direct starting and mechanical brake force braking. The impact of starting and braking is large, causing significant damage to the mechanical structure and mechanism, and electrical components are also prone to damage. At the same time, it is easy to cause materials in the elevator to fall, which not only affects the construction speed but also the efficiency of the construction enterprise. Especially on dual-use construction elevators, there are great safety hazards.
With the continuous development of China's construction industry and the continuous improvement of construction mechanization level, the requirements for the manufacturing quality and overall skill level of construction elevators are also increasing. The use of variable frequency speed regulation technology can achieve stepless speed regulation of the acceleration, deceleration, and braking process of the construction elevator, reducing the impact of the motor on the mechanical system during start-up and shutdown, improving the smoothness and comfort of the construction elevator operation, extending the service life of the construction elevator, and greatly improving the working power. The application of frequency converters in construction elevators will become a development trend in the construction machinery industry.
The TS1000 series is a professional specialized aircraft developed by Sifang Electric for construction elevators. It integrates high-performance vector frequency converters, braking units, lifting weight limiters, construction elevator logic control boards, leveling expansion cards, and specialized operating table machine components, providing manufacturers with a complete one-stop processing solution.
The product focuses on addressing difficult issues such as the timing of the release brake and the leveling function of the construction elevator. Optimization planning has been carried out in new floor learning, acceleration control during start-up, leveling speed curve, interactive interface, and other aspects. Professional specific logic ensures timing control, improves system safety and comfort, and the leveling control algorithm achieves accurate and active leveling of the elevator.
(1) Modular planning, one-stop processing solution, integrated Chengdu High
The integrated planning of the driver and low-voltage electrical cabinet includes a dedicated frequency converter, braking unit, lifting weight limiter, construction elevator dedicated logic control board, leveling expansion card, and GPS/GPRS monitoring system; The components in the low-voltage electrical cabinet (main circuit breaker, main contactor, isolation transformer, release contactor, lighting circuit breaker) can be selected by customers themselves, making it easy for construction elevator integrators to integrate. The system device wiring is simple and easy to transport, saving costs such as device data and labor.
(2) Intelligent operation channel, simple and intuitive operation
The TS1000 dedicated console integrates a human-machine interface, floor calling, floor buttons, electric bells, sockets, operation buttons, and control handles, with floor calling function. Call information and all operating conditions and signals of the elevator are clearly displayed on the LCD screen. The human-machine interface is intuitive, reducing labor intensity and minimizing potential accidents.
(3) Built in braking unit and weight limiter, customers do not need to configure separately
The driver is equipped with a 1:1 power IGBT braking unit, which can be directly connected to the braking resistor to achieve rapid shutdown.
The human-machine interface displays the current load capacity of KG, and the weighing signal directly controls the driver to complete the weight limit protection function. It is easy to use, has high accuracy, and is reliable and durable.
(4) Built in GPS/GPRS communication port
Built in GPS/GPRS communication port, used for satellite positioning and long-distance monitoring, with long-distance locking and unlocking functions for easy management of installment payment customers (requires a dedicated GPS module).
(5) Crane specific brake timing, safe and reliable
The lifting specific brake timing control monitors the output frequency and torque of the frequency converter, and uses a dual logic brake signal to ensure that the motor output of the elevator meets the torque requirements when starting up or down, avoiding "hook slipping" and also avoiding vibration caused by motor impact on the mechanical system when starting up or down.
(6) Start stop comfort
Specialized S-curve acceleration and deceleration planning greatly improves the comfort of starting and stopping. When the machine is stopped, the frequency converter truly completes the braking under the "zero speed" condition, with smooth leveling, low impact, and reduced gear wear. The durability of the disc brake is greatly improved.
(7) Active leveling control
Active leveling control uses a section of speed leveling, which has a fast leveling speed and a leveling accuracy of ≤ 1cm. The floor learning management interface has a user code, and the learning height can be adjusted, making the operation simple and reliable.
(8) The device is sensitive
Embedded devices inside the cage save space inside the hanging cage.
(9) Sensitive wiring
Sensitive control circuit wiring, the control card uses plug-in terminal blocks, and the console can choose terminal wiring or aviation socket wiring methods.
(10) Waterproof planning IP54
Whole machine waterproof planning, passing rainproof test, IP54 waterproof rating.
(11) Easy installation, debugging, and protection
The dedicated logic control board for construction elevators integrates hardware protection logic for elevators, with LED status indicators and silk screen markings for input and output. The control terminals are selected as ribbon or plug-in terminals, and the system device wiring is convenient; The driver adopts modular planning, which reduces device working hours, improves production power, and reduces assembly failure rate; The system is equipped with a dedicated control program, and the frequency converter parameters can be set to operate from the factory. The system device is simple and easy to debug, and the protection and repair are concise and intuitive.
The Sifang TS1000 construction elevator drive integrated machine has complete safety protection functions, convenient installation, debugging, and protection. The elevator has soft start and stop, no impact, sliding, or shaking, and operates smoothly and comfortably, reducing the impact of mechanical equipment. The friendly interactive interface and active leveling function greatly reduce the workload of operators, improve work power, and receive high praise from customers. It has outstanding promotion and application value in construction elevators.
