Background
Some equipment in the gypsum board manufacturing process sometimes needs to be moved at very low speeds and sometimes very high speeds. The existing walking device realizes speed change through frequency conversion, and the applicable frequency conversion range of the motor is limited, so that two walking speeds with extremely large difference cannot be met.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a double-speed walking device.
A double-speed walking device is characterized in that a frame is connected with a first normally-open electromagnetic clutch, a second normally-open electromagnetic clutch and a double-output-shaft speed reduction motor, the double-output-shaft speed reduction motor is connected with a gearbox, output shafts at two ends of the gearbox are respectively connected with a first coupler and a second coupler, the other end of the first coupler is connected with the first normally-open electromagnetic clutch, an output shaft of the first normally-open electromagnetic clutch is connected with a belt wheel for the electromagnetic clutch, the belt wheel for the electromagnetic clutch is connected with a first large belt wheel through a triangular belt, the other end of the second coupler is connected with the second normally-open electromagnetic clutch, an output shaft of the second normally-open electromagnetic clutch is connected with a second large belt wheel, the second large belt wheel is connected with a small belt wheel through a triangular belt, a transmission shaft is connected with a bearing and a bearing support, two ends of the transmission shaft are respectively connected with the first large belt wheel and the small belt wheel, ends of the transmission shaft are respectively connected with a gear, the support shaft is connected with the bearing and the bearing support, the bearing support is connected with the bearing support, the bearing is connected with the frame, a support is fixed on gypsum board production equipment frame, and the gear is meshed with a rack.
The V-belt is a synchronous belt, a chain, a toothed chain or a gear transmission structure, and the electromagnetic clutch is a clutch controlled pneumatically or hydraulically.
The invention has the advantages that the vehicle can run at two different speeds without frequency change by the two clutches and two sets of transmission systems with different transmission ratios and the clutching of the clutches. The speed regulation in a larger range can be realized by matching the up-converter. The motor can have two moving speeds without frequency conversion equipment. The problem that the walking speed cannot be realized due to the fact that the walking speed exceeds the frequency conversion range of the motor is solved.
