The utility model discloses simple structure, the circuit repacking is convenient, realizes the converter of driving motor sharing that lifts by crane with the translation and control that operating repair is with low costs, effectively reduces the port machine and lifts by crane the system device cost, effectively save simultaneously the space and the heavy burden of lifting by crane the platform, reduced the working cost and the cost of maintenance of the port machine system of lifting by crane.
Description
Technical field
The utility model relates to machine tackling system control technology field, port, and particularly a kind of pair of HCT motor drives the converter circuit switched.
Background technology
In the machine tackling system of port, crane loading motor is different with translation motor power, usual lifting drive motors and pan drive motor are controlled by different frequency converters respectively, realize lifting, translation completes the whole course of work, use this system to have 2 weak points, one is lifting translation each corresponding Frequency Converter Control respectively, and cost increases; Two is that machine hoisting platform locus, port is limited, and the heavy burden also increasing platform placed by multiple stage frequency converter simultaneously.
Summary of the invention
The utility model is for current port machine tackling system lifting translation each corresponding Frequency Converter Control respectively, and cost is large, takies machine hoisting platform locus, port, increases the deficiencies such as the heavy burden of platform, provides a kind of pair of HCT motor to drive the converter circuit switched.The technical solution of the utility model is embodied as:
A kind of pair of HCT motor drives the converter circuit switched, comprise frequency conversion tank and bi-motor auxiliary tank, output contactor in frequency converter, motor change-over circuit and cabinet is provided with in described frequency conversion tank, auxiliary contactor is provided with in described bi-motor auxiliary tank, in described cabinet, output contactor and one end of auxiliary contactor are for being connected motor, in described cabinet, output contactor is connected described motor change-over circuit with the other end of auxiliary contactor, and described motor change-over circuit connects described frequency converter and can switch motor drive circuit.
As the preferred technical scheme of the utility model, described motor change-over circuit has two motor conversion output, and in described cabinet, output contactor is connected from different motor conversion output with auxiliary contactor.
Further, described motor change-over circuit comprises two HCT motor transition card.
Further, described motor change-over circuit comprises path indicator light, is used to indicate path information and the fault message of current connection, maintains easily maintenance.
Further, described motor change-over circuit comprises independent current source, and described motor change-over circuit is driven by described independent current source, avoids the impact of port machine tackling system fault.
Further, described independent current source is rechargable power supplies.
Advantage of the present utility model:
The two HCT motor of the utility model drives the converter circuit structure switched simple, circuit repacking is convenient, the drive motors that can realize lifting and translation shares a Frequency Converter Control, two HCT motor drives the Maintenance and Repair cost of the converter circuit switched low simultaneously, effectively reduces port machine tackling system equipment cost; Adopt a Frequency Converter Control, effectively save space and the heavy burden of hoisting platform, reduce job costs and the maintenance cost of port machine tackling system.

Fig. 2 is crane operating status schematic diagram.
Embodiment
Embodiment:
A kind of pair of HCT motor drives the converter circuit switched, comprise frequency conversion tank and bi-motor auxiliary tank, output contactor in frequency converter and cabinet is provided with in frequency conversion tank, in cabinet, output contactor connects lifting motor, motor change-over circuit is provided with between output contactor in frequency converter and cabinet, motor change-over circuit comprises two HCT motor transition card and has two motor conversion output, is provided with auxiliary contactor in bi-motor auxiliary tank, and auxiliary contactor connects translation motor; Output contactor and auxiliary contactor in two motor conversion output difference connecting cabinets of motor change-over circuit; Motor change-over circuit comprises path indicator light, and motor change-over circuit is driven by independent current source.
Because lifting motor and translation motor are not carry out work simultaneously, crane operating status figure as shown in Figure 2, comprises three operating states: (1) is crane work initial condition; (2) be crane work lifting state; (3) be crane work translation state.When crane frequency converter 3 starts initial, lifting motor off-duty, crane is in work initial condition; When frequency converter 3 starts, in cabinet, output contactor is closed connects, and system circuit lifting motor obtains electric operation, and crane is in work lifting state, and crane operation work is lifted by crane, and object is raised to work desired height; When object is raised to work desired height, make on inverter supply switch dual motor assist cabinet auxiliary contactor loop by the two HCT motor conversion of frequency converter motor internal change-over circuit, auxiliary contactor is closed to be connected, and translation motor startup optimization, by object translation to desired location.The alternation under the control of the converter circuit of two HCT motor driving switching of lifting motor and translation motor, realizes the frequency converter system of crane of Frequency Converter Control two electric motor loop.When two HCT motor drives the converter circuit switched to work, path indicator light indicates the path information of current connection, and when two HCT motor drives the converter circuit switched to break down, path indicator light indication fault information, maintains easily maintenance.
