An online motor braking torque detector and its detection method

Abstract

The invention relates to an online detector and a detection method for motor braking torque. A wind motor which operates on line is used as a selection machine. A force transmission component and a mounting window are used for being connected with a force measuring device and are additionally arranged. When detection is performed, the force measuring device and a force transmission unit of the force measuring device are in butt joint with the mounting window, so that a force transmission gear and a transmission gear are meshed in a linkage mode and fixed; finally, the force transmission shaft end of the force measuring device is sleeved with a torque wrench, and the purpose of online detection is achieved by manually pulling the torque wrench. According to the online detector and the detection method for the motor braking torque, the problems that in an existing wind power generation device which operates on line, real-time detection cannot be performed on safety braking torque, the technical conditions of the wind power generation device and the technical conditions of a pitch motor cannot be determined and guaranteed, and whether the wind power generation device is in safe operation or not cannot be determined and guaranteed are solved; the online detector and the detection method are suitable for being used for detection of various existing motors which operate on line and especially suitable for detecting the safety braking torque of the wind power generation device.

Description

technical field [0001] The invention relates to an online detector for braking torque of a motor and a detection method thereof. Background technique [0002] In the existing wind power generation equipment running on-line in coastal and offshore areas, the safety braking torque of the pitch motor during operation does not have the ability to detect in real time. In case of extreme weather, there is a lack of control over the safe operation of wind power generation equipment capacity, and cannot confirm and guarantee the technical status of wind power generation equipment and pitch motors and whether wind power generation equipment is in safe operation. [0003] If the above-mentioned pitch motor structure used online can be connected with the torque detection equipment, only the main shaft extension and the tail shaft can be coaxially connected with external devices, but the main shaft extension has been connected to the reducer during work and cannot be used; The tail sha...

Problems solved by technology

[0002] In the existing wind power generation equipment running on-line in coastal and offshore areas, the safety braking torque of the pitch motor during operation does not have the ability to detect in real time. In case of extreme weather, there is a lack of control over the safe operation of wind power generation equipment capacity, unable to confirm and guarantee the technical status of wind power generation equipment and pitch motors and whether the wind power generation equipment is in safe operation

[0003] If the above-mentioned pitch motor structure used online can be connected with the torque detection equipment, only the main shaft extension and the tail shaft can be coaxially connected with external devices, but the main shaft extension has been connected to the reducer during work and cannot be used; The tail shaft of the motor is connected to the encoder when it is working, and the shaft length is only 10mm, which requires high precision and poor force resistance, so it is not suitable for detecting braking torque here.

Therefore, when this type of pitch motor structure is working, there is no suitable position and mechanism to detect the safe braking torque of the motor
