Abstract
The utility model relates to a frequency conversion control device of a remote control crane, which is characterized in that a three-phase power supply is connected with a frequency converter through a main circuit breaker; a control power supply is connected with the frequency converter through a controlling circuit breaker and a reversing contactor in sequence, and the frequency converter is connected with a motor; and the frequency converter is mounted in a frequency conversion control box and connected with the electric control panel of the crane. Compared with the prior art, the utility model has the benefits that the frequency conversion control device is suitable for the crane control system and can ensure the stable operation of the crane, so as to reduce the equipment damage and reduce the production accident rate.
Description
Technical field
The utility model relates to a kind of control setup, particularly relates to a kind of remote control crane frequency-converting control device.
Background technology
The remote control crane belongs to the suspension type single-beam lifting, electrical equipment control is simple forward and reverse without speed control, when the large load weight of handling, because the inertia when startup and parking, make cucurbit hang significantly long-drawn-out pendulum, pull energetically hanging the generation of tugboat and transmission device, damage to equipment is very large, thereby affected the service life of equipment, the fault that often occurs: motor burning, steel cable goes out groove, limit vibration, rope guide damages, steel stranded or fracture, the gib head damage, hanging thing falls etc., personal safety to operating personal threatens, and human casualty accident easily occurs, and has very large potential safety hazard.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, easy to operate remote control crane frequency-converting control device.
In order to address the above problem, the utility model by the following technical solutions:
A kind of remote control crane frequency-converting control device, three phase mains is connected with frequency converter by line circuit breaker, and the control power supply is connected with frequency converter with reversing contactor by the control circuit breaker successively, and frequency converter is connected with motor.
Described frequency converter is installed in the variable frequency control case and with the electrical control dish of crane and is connected.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is applicable to the overhead crane control system, can guarantee the smooth running of crane, thereby has alleviated equipment damage, has reduced the industrial accident rate.
Description of drawings
Fig. 1 is the utility model structured flowchart.
The specific embodiment
A kind of remote control crane frequency-converting control device, as shown in Figure 1, comprise three phase mains, control power supply, line circuit breaker, control circuit breaker, reversing contactor, remote controller, receiver of remote-control sytem, frequency converter and motor, three phase mains is connected with frequency converter by line circuit breaker, the control power supply is connected with frequency converter with reversing contactor by the control circuit breaker successively, the control circuit breaker is connected with receiver of remote-control sytem, and remote controller is connected with reversing contactor by receiver of remote-control sytem, and frequency converter is connected with motor.Power supply connects frequency converter by circuit breaker powers to motor, and remote controller control reversing contactor is selected motor drive direction, and frequency converter is controlled motor.Frequency converter is installed in the variable frequency control case and with the electrical control dish of crane and is connected, and converter parameter is regulated, and realizes starting and the parking of motor, realizes simultaneously the control of minimum and maximum speed.。
