Problems solved by technology
[0002] At present, the electrical control system of the single-girder crane that controls the motor of the traditional single-girder crane in the process of lifting, forward and backward, and translation uses a contact AC contactor. It is easy to produce arc light, the mechanical mechanism is easy to be mechanically stuck and worn out, the disadvantages are large and heavy, and there is no current protection function, which is easy to cause major accidents

The invention relates to a noncontact control system of a single beam crane. The noncontact control system comprises a control system shell; a power supply main switch is arranged in the control system shell; the power supply main switch is connected with an external power supply; a lift motor is connected with the power supply main switch, a controlled silicon Q1, a controlled silicon Q2, a controlled silicon Q3 and a controlled silicon Q4; a cart translation motor is connected with the power supply main switch, a controlled silicon Q5, a controlled silicon Q6, controlled silicon Q7 and a controlled silicon Q8; and a trolley translation motor is connected with the power supply main switch, a controlled silicon Q9, a controlled silicon Q10, a controlled silicon Q11 and a controlled silicon Q12. The noncontact control system has the advantages of reducing the electric cost of the crane, reducing the space occupied by the electric part of the crane, improving the installation speed and improving the intellectualization of the electric part of the single beam crane.
Description
technical field [0001] The invention relates to a non-contact control system for a single-girder crane that controls the motor of the single-girder crane during the lifting, front-back, translation, and process of the single-girder crane. Background technique [0002] At present, the electrical control system of the single-girder crane that controls the motor of the traditional single-girder crane during the lifting, forward and backward, and translation processes uses a contact AC contactor. It is easy to produce arc light, the mechanical mechanism is easy to be mechanically stuck, worn out, large in size and heavy, and there is no current protection function, which is easy to cause major accidents. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies in the prior art and provide a single-girder crane that can reduce the electrical failure rate, compress the lifting electrical cost, reduce the space occupied by the lifting electr...
