1. the transformer erecting device that a fail safe is high, for closure around and hold transformer (208), comprise main housing case (2) and cover the pivoted door device (209) of opening of described main housing case (2) removedly, the first side of described pivoted door device (209) is hinged on described main housing case (2), second side engages with described main housing case (2) opening or closing, wherein, described pivoted door device (209) can slide up and down to be provided with coalescing lock pin device (20) at described second side place, described coalescing lock pin device is provided integrally with locking coupler body (60) and realizes described pivoted door device (209) to be locked on described main housing case (2) in order to interior also the joint with the inside undercut portion of described shrinkage pool (200) by hook end (601) of shrinkage pool (200) stretched in the wall portion of described main housing case (2) towards described main housing case (2), the inner side of described pivoted door device (209) is also provided with and drives recess (309) in order to engage with drive block (30) thus to be driven also along vertical direction and horizontal direction by described drive block (30) and then make described locking coupler body (60) unlock, the inner side place of described drive block (30) is provided with and drives profile portion (303) in order to coordinate with the coupling recess (402) by screw rod (50) in the internal thread slide block (40) of screw drive, described internal thread slide block (40) can be slided in the cavity (500) in the described wall portion of described main housing case (2), be wall portion blocking part (250) between described cavity (500) and described shrinkage pool (200), described driving profile portion (303) is slidably matched with the recess inclined-plane (4021) of described coupling recess (402) by protruding inclined-plane (3031), contraction spring (431) is connected with between described drive block (30) and described internal thread slide block (40), upper end and the described drive block (30) of described contraction spring (431) are hinged by upper jointed shaft (301), lower end and described internal thread slide block (40) hinged by lower jointed shaft (401), when described driving profile portion (303) is matched with in described coupling recess (402), the bearing of trend of described contraction spring (431) is parallel with the bearing of trend of described protrusion inclined-plane (3031) and recess inclined-plane (4021), when described screw rod (50) promotes described internal thread slide block (40) towards described wall portion blocking part (250) slip under the driving of drive motors (501), by the effect between described protrusion inclined-plane (3031) and recess inclined-plane (4021), described drive block (30) drives described coalescing lock pin device (20) slide thus described hook end (601) is disengaged with the inside undercut portion of described wall portion, now the vertical sliding motion junction surface (302) of the end of the close described wall portion blocking part (250) of described drive block (30) is against described wall portion blocking part (250) side, when described internal thread slide block (40) continues motion, the described protrusion inclined-plane (3031) of described drive block (30) is outwards slided relative to described recess inclined-plane (4021), thus described pivoted door device (209) by top from described main housing case (2) wall portion thus formed with the lateral surface of described wall portion between gap (600), described drive motors (501) outer surface is coated with radiating fin (5011), the heat absorption produced when described radiating fin (5011) is in order to run described drive motors (501) also dissipates, when preventing described drive motors (501) long-play, temperature is too high and burn, the described main housing case (2) of described cavity (500) top and described cavity (500) bottom is equipped with limit sensors (5012), described limit sensors (5012) is touch sensor, after described internal thread slide block (40) touches described limit sensors (5012), send signal and control described drive motors (501) and stop operating, described limit sensors (5012) is in order to prevent the slip excess of stroke in the cavity (500) of described internal thread slide block (40) in the described wall portion of described main housing case (2).
