Abstract

The invention relates to the field of safety protection devices, in particular to a motor zero-speed monitoring and protective door interlocking control device. According to main points of the technical scheme, the motor zero-speed monitoring and protective door interlocking control device comprises a zero-speed monitoring module and a protective door opening-closing device; the zero-speed monitoring module is connected with a motor and used for detecting residual voltage of motor winding and outputting a logic signal; and the protective door opening-closing device is used for receiving and responding the logic signal from the zero-speed monitoring module. The motor zero-speed monitoring and protective door interlocking control device has the characteristics that the zero-speed monitoringmodule is arranged so that a protective door can be locked when the motor rotates in accordance with inertia, the protective door is allowed to be opened when the motor is stopped, and the risk of personal injury is avoided.

Description

technical field [0001] The invention relates to the field of safety protection devices, in particular to a motor zero-speed monitoring and protection door interlock control device. Background technique [0002] During the crushing process of high-speed rotation, although the power supply of the motor has been cut off, the motor will still rotate for a period of time due to the rotational inertia of the motor. If the door of the crushing studio is opened for operation at this time, not only will there be hidden dangers to personal safety, but also dust pollution. Therefore, when designing the control circuit, the concepts of zero-speed monitoring and interlocking control of the protective door are introduced. [0003] In view of the above problems, our country has the following patents: [0004] Patent authorization announcement number: CN106227145A, which discloses a dual power supply damper control system, which involves the field of safety production technology. The syste...
