Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance auxiliary tooling, and in particular relates to a maintenance auxiliary tooling for a wind turbine generator set. Background Art

[0002] Goldwind's 1.5MW unit uses a variety of sensors to provide reliable data signal support for the stable and safe operation of the wind turbine. The accuracy and sensitivity of the sensor measurement signal determine the timeliness and accuracy of the wind turbine control response. Incorrect sensor signals may cause the wind turbine to shut down, reduce the wind turbine's availability, and cause power generation losses. In serious cases, the wind turbine may use incorrect sensor signals to issue incorrect control commands, which will have a serious impact on the safe operation of the wind turbine.

[0003] During regular maintenance work, it is necessary to accurately measure and calibrate the trigger gap of the proximity switch sensor used in the unit. When the maintenance standards are relatively clear, the maintenance quality cannot be effectively controlled and guaranteed due to the lack of professional standardized maintenance tools or tooling. The execution of some measurement items has large deviations, especially the lack of sensor installation process measurement and verification links.

[0004] Generally speaking, the measuring tools used in the regular maintenance of units are numerous and complex, and it is inconvenient for maintenance personnel to switch between multiple tools. Utility Model Content

[0008] Through the above technical solution: when in use, the first tooling with a length of 380mm and a thickness of 2.5mm is connected to the first tooling with a locking screw. Because its thickness is exactly 2.5mm, which is consistent with the process requirements for the proximity switch installation trigger gap, the tooling can be directly used to measure and calibrate the proximity switch trigger gap used on the fan. The measurement efficiency is high, the measurement results are accurate, and rapid verification can be achieved. Therefore, it can be easy for the unit maintenance personnel to operate.

[0009] The utility model is further configured that one side of the first tooling is in an F-shaped structure, and a scale line is engraved on the F-shaped ruler head on one side of the first tooling.

[0010] Through the above technical solution: the setting of the scale line can quickly and directly measure the effective thickness of the yaw brake pad used on the wind turbine.

[0011] The utility model is further configured such that both sides of the bottom of the second tooling are fixedly connected with rubber-coated strong magnets.

[0012] Through the above technical solution: the setting of rubber-coated strong magnet can be directly adsorbed on the variable pitch bearing when in use.

[0013] The utility model is further configured such that a parallel light source is arranged on the top of the first tooling, a magnetic block is fixedly connected to the bottom of the parallel light source, and the magnetic block is magnetically connected to the first tooling.

[0014] Through the above technical solution: the setting of the magnetic suction block can be used to install the parallel light source.

[0015] The utility model is further configured such that a convex corner is provided at one end of the second tooling, and the convex corner is integrally formed with the second tooling.

[0016] Through the above technical solution: the convex angle can be set to be aligned with the 0 degree of the blade zero disc.

[0017] The utility model is further configured such that the second tooling has a length of 300 mm and a thickness of 3 mm.

[0018] Through the above technical solution: the effective sag height of the tower cable at the saddle bridge can be directly measured and calibrated.

[0019] The utility model is further configured as follows: the first tooling and the second tooling are placed on a box body; a box cover is hinged at one end of the top of the box body; and the box cover is fixed to the box body by a lock.

[0020] Through the above technical solution: the setting of the box body can store and place the first tooling and the second tooling.

[0021] The beneficial effects of the utility model are:

[0022] 1. When the auxiliary tooling for maintenance of wind turbines is used, the first tooling with a length of 380 mm and a thickness of 2.5 mm is connected to the first tooling with a locking screw. Because its thickness is exactly 2.5 mm, which is consistent with the process requirements for the installation trigger gap of the proximity switch, the tooling can be directly used to measure and calibrate the trigger gap of the proximity switch used on the wind turbine. The measurement efficiency is high, the measurement results are accurate, and rapid verification can be achieved. Therefore, it can achieve the effect of facilitating the operation of the unit maintenance personnel.
