Detailed description of the invention
Shown in Fig. 5, wind turbines rotor automatic locking apparatus of the present utility model, including control system a, motor-driven turning mechanism b, shift sensing mechanism c, hydraulic pressure wind wheel locking mechanism d。Described control system a may be mounted on the speed-changing gear box 4 of wind turbines rotor main shaft 3 one end, is used for controlling motor-driven turning mechanism b and carries out speed end electric barring。Described shift sensing mechanism c is for judging the position of lockhole, and after position, hole aligns, described control system a controls hydraulic pressure wind wheel locking mechanism d and carries out last locking work。
Described control system a, including PLC composite module, uses PLC composite module to process with regard to lock wind wheel order and displacement transducer signal, and controls motor-driven turning mechanism start and stop and the speed of service, be simultaneously connected with Hydraulic Station and control the action of hydraulic pressure wind wheel locking mechanism。
Described motor-driven turning mechanism b includes turning motor b1, high speed brake disc b2, high-speed brake b3。Described high speed brake disc b2 is arranged on the high-speed output end of speed-changing gear box 4, its outer ring is toothed around b4, these gear teeth b4 engages with the low-speed gear b5 being arranged on turning motor b1 output shaft, and the caliper b6 of described high-speed brake b3 is directed at described high speed brake disc b2。By situation, the upper and lower sides of described high speed brake disc b2 is respectively mounted high-speed brake b3。Described high-speed brake is prior art, does not repeat at this。
Described displacement transducer mechanism c includes proximity switch c1 and the position dish c2 being arranged on wind wheel lock price fixing 1, and lockhole 2 position of described position dish c2 correspondence wind wheel lock price fixing 1 arranges labelling point c3, described position dish c2 can integrative-structure with wind wheel lock price fixing 1。Motor-driven turning mechanism quick rotation, makes wind wheel start to rotate。When lockhole 2 first time of wind wheel lock price fixing 1 just to the lock pin d1 of hydraulic pressure wind wheel locking mechanism d time (proximity switch c1 alignment mark point c3), described proximity switch c1 sends signal to controlling system a, the described control system a signal according to proximity switch c1, the turning motor b1 ordering described motor-driven turning mechanism b reduces rotating speed, carries out last accurate lock work。
In such scheme, described labelling point c3 is specially the perforate being arranged on circumferentially particular arrangement on the dish c2 of position, " 0 " signal is sent during described proximity switch c1 alignment apertures, otherwise sending " 1 " signal, described position dish is provided with specific identification serial number (the particular arrangement identification according to perforate) in each lockhole position。When the lockhole 2 of wind wheel lock price fixing 1 is just to lock pin d1, described proximity switch c1 sends signal specific to controlling system a, the turning motor b1 of the described described motor-driven turning mechanism b of control system a order reduces rotating speed, turning motor is rotated by low-speed gear and drives high speed brake disc, by gear-box speedup function thus realizing rotating wind wheel function。
Optimizing such scheme further, described proximity switch c1 is preferably 4 and is arranged side by side, it is possible to identify wind wheel positive-negative rotation state, improves accuracy of identification, it is prevented that erroneous judgement。The lock pin d1 of described hydraulic pressure wind wheel locking mechanism d is provided with position sensor d2。To controlling system feedback lock pin whether lock into place or reset puts in place, unit safety grade can be improved。
When staff clicks locking wind wheel functional keys, when wind wheel rotates lockhole just to lock pin, it is assumed that 4 proximity switches send the signal specific that sequence number is 1011, (proximity switch is sequencing number from left to right, and only have the 2nd proximity switch alignment apertures, when wind wheel rotates lockhole not to lock pin, 4 proximity switches send non-1011 signals, and signal specific can be arranged as required to into other sequence number, such as 1010 etc.)。After control system first time obtains 1011 orders (first lockhole coarse positioning), order turning motor is reduced rotating speed, thus realizing being accurately positioned of second lockhole。The while that behind location, high speed brake disc being checked by order high-speed brake by control system, turning motor power-off stops operating, it is prevented that wind wheel is rotated further by。It is possible to prevent erroneous judgement, it is achieved being accurately positioned of displacement transducer mechanism by above-mentioned 4 signal specific。Signal specific figure place can be arranged as required to。
After location, control system start-up Hydraulic Station to hydraulic jack 5 for pressure-driven operator link 6, thus realizing lock pin to enter into lockhole。After lock pin is completely into lockhole, position sensor will feed back to control system, and high-speed brake will unclamp。Now locking wind wheel functional keys red light lights, and unit will be in wind wheel maintenance state, and any order all can not start blower fan。After maintenance, staff clicks locking wind wheel functional keys (cancelling locking wind wheel function) again。Control system controls high-speed brake and checks high speed brake disc, in order to avoid strong wind rotates wind wheel, causes that lock pin resets and is obstructed。Then starting Hydraulic Station drives operator link to reset to hydraulic jack voltage supply power, resets thus realizing lock pin。After lock pin resets completely, position sensor will feed back to control system。Controlling system command high-speed brake to unclamp, wind wheel can normal rotation。Now locking wind wheel functional keys red light goes out, and releases wind wheel maintenance state, and blower fan can normally start。
Described in upper, not utility model is done any pro forma restriction, although utility model discloses as above with preferably case study on implementation, but it is not limited to utility model, any those skilled in the art, without departing within the scope of technical solutions of the utility model, when structure and the technology contents of available the disclosure above make a little equivalent case study on implementation changing or being modified to equivalent variations, but every content without departing from technical solutions of the utility model, according to any simple modification that above case study on implementation is made by technical spirit of the present utility model, equivalent variations and modification, all still in true new technique aspects。
