Description
Technical field
The present invention relates to a kind of anchor winch, especially relate to a kind of frequency changing driving system of anchor winch.
Background technology
At present, the type of drive of anchor winch is that hydraulic-driven or three-speed motor drive, but along with people more and more pay attention to energy-conservation concept, existing hydraulic-driven mainly is comprised of main axis transmission system of hydraulic power unit, hydraulic motor, hydraulic control valve, electric cabinet, reduction box and anchor winch etc.Because the hydraulic system components and parts are many, unavoidably there is hydraulic fluid leak, environment there is certain pollution, shipyard need to be installed and clean fluid pressure line when the hydraulic anchor winch is installed, and needs a large amount of artificial and costs.
The anchor winch that three-speed motor drives only has third speed, cannot realize stepless speed regulation, requires to have in the situation of automatic tension requirement the shipowner, needs to increase other components and parts such as load axle and amplification board and could realize that cost increases large.
Summary of the invention
Purpose of the present invention is exactly a kind of simple in structure, stable performance is provided in order to overcome the defective that above-mentioned prior art exists, and can realizes the anchor winch frequency changing driving system of stepless speed regulation.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of frequency changing driving system of anchor winch, comprise remote operation master controller, electric cabinet, frequency converter, variable-frequency motor and anchor winch driving main shaft, described remote operation master controller connects electric cabinet, described electric cabinet connects frequency converter, this frequency converter is connected with variable-frequency motor, and the output shaft of this variable-frequency motor is connected with anchor winch driving main shaft;
The remote operation master controller sends speed controling signal to electric cabinet, after receiving this speed controling signal by electric cabinet, send frequency variation signal to frequency converter, frequency converter changes the incoming frequency of variable-frequency motor according to this frequency variation signal, thereby regulate the output speed of variable-frequency motor, anchor winch driving main shaft is carried out stepless speed regulation.
Described electric cabinet comprises the PLC system.
The output shaft of described variable-frequency motor is provided with the encoder for detection of output torque, and this encoder connects the PLC system of electric cabinet, and the PLC system carries out automatic tension according to the output torque that detects and regulates.
Automatic tension is regulated and is specially: the PLC system compares output torque and the predetermined torque that detects, if output torque, is then controlled the variable-frequency motor counter-rotating greater than predetermined torque, reduces tension force; If output torque less than predetermined torque, is then controlled the variable-frequency motor forward, increase tension force.
Compared with prior art, the present invention has adopted the mode of frequency conversion drive, and starting current is very little, therefore little to the impact of power supply, also very energy-conservation, loss electric energy in operation only, not loss when stopping, this and traditional type of drive are very different also more environmental protection.Do not need extra tensiometer test pulling force when using frequency conversion drive, on frequency converter, all can automatically show.And because wiring is few, installation connects more simple and convenient, and stepless speed regulation makes operation more steadily reliable.And by encoder detection output torque, carry out automatic tension and regulate the function that can prevent that moment of torsion is excessive or transship, can also reduce the wearing and tearing of hawser, finish high-quality work with cheap cost, can realize easily the automatic tension function in the situation that does not increase other components and parts, frequency conversion drive also provides Long-distance Control.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of frequency changing driving system of anchor winch comprises remote operation master controller 1, electric cabinet 2, frequency converter 3, variable-frequency motor 4 and anchor winch driving main shaft 5.Remote operation master controller 1 connects electric cabinet 2, is provided with PLC system 21 in the electric cabinet 2, and connects frequency converter 3, and this frequency converter 3 is connected with variable-frequency motor 4, and the output shaft of this variable-frequency motor 4 is connected with anchor winch driving main shaft 5.In order to realize the automatic tension adjusting, the output shaft of variable-frequency motor 4 also is provided with the encoder 41 for detection of output torque, and this encoder 41 connects the PLC system 21 of electric cabinets 2, and PLC system 21 carries out automatic tension according to the output torque that detects and regulates.
The specific works process that the present invention carries out stepless speed regulation is: the remote operation master controller sends speed controling signal to electric cabinet, after receiving this speed controling signal by the PLC system of electric cabinet, send frequency variation signal to frequency converter, frequency converter changes the incoming frequency of variable-frequency motor according to this frequency variation signal, thereby regulate the output speed of variable-frequency motor, anchor winch driving main shaft is carried out stepless speed regulation.
The detailed process that automatic tension is regulated is: the PLC system compares output torque and the predetermined torque that detects, if output torque, is then controlled the variable-frequency motor counter-rotating greater than predetermined torque, reduces tension force; If output torque less than predetermined torque, is then controlled the variable-frequency motor forward, increase tension force.
The present invention is owing to adopted the mode of frequency conversion drive, and starting current is very little, and is therefore little to the impact of power supply, also very energy-conservation, loss electric energy in operation only, and not loss when stopping, this and traditional type of drive are very different also more environmental protection.Do not need extra tensiometer test pulling force when using frequency conversion drive, on frequency converter, all can automatically show.And because wiring is few, installation connects more simple and convenient, and stepless speed regulation makes operation more steadily reliable.And by encoder detection output torque, carry out automatic tension and regulate the function that can prevent that moment of torsion is excessive or transship, can also reduce the wearing and tearing of hawser, finish high-quality work with cheap cost, in the situation that does not increase other components and parts, can realize easily the automatic tension function.And adopt the remote operation master controller to carry out Long-distance Control, handled easily.
