The specific working principle of the invention is as follows: when the internal parts of the automobile need to be maintained, the controller 11 is opened, the controller 11 starts the winch 22 to lower the rope 221, the supporting block 6 drives the connecting block 7 to synchronously move, the connecting block 7 moves downwards to drive the lifting hook 85 to synchronously move, and the lifting hook 85 lifts the parts, so that the subsequent maintenance is convenient.
The support block 6 can drive the slide post 55 and slide along the inner wall of slide tube 3 when moving down for slide tube 3 plays the linking effect with slide post 55 to support block 6, thereby reduce the shake range that produces when support block 6 removes, avoid the part to lead to the fact the threat to personnel's safety when lifting by crane, simultaneously slide post 55 slides down and can drive slide ring 5 and slide along the inner wall of slide tube 3, make controller 11 start band-type brake servo motor 4 this moment, band-type brake servo motor 4 can drive pivot 41 clockwise rotation, pivot 41 rotates and can drive slide ring 5 coaxial rotation, when slide ring 5 rotates to certain angle, slide ring 5 inside fixed mounting's first spring 52 can promote slider 53 and slide along the inner wall of spout 51, make slider 53 and hidden groove 32 block, this moment slide ring 5 is spacing unable to slide by slider 53 and hidden groove 32, and because slider 53 hidden groove 32 is the inclined plane setting, make slide ring 5 can not make slide along slide tube 3 this moment, band-type brake servo motor 4 can drive pivot 41 clockwise, pivot 41 rotates, slide ring 5 coaxial rotation can be driven by flexible connection, when rotating to certain angle, and then can make and can keep placing on the fixed part in order to be more convenient for the maintenance to keep the aerial part to be placed on the table surface 85.
When the power failure or the broken condition of rope 221 appears, because the action of gravity auto parts can make lifting hook 85 drive backup pad 6 quick whereabouts, backup pad 4 can drive the slide post 55 and slide along the inner wall of slide section of thick bamboo 3 fast, slide post 55 can drive slip ring 5 synchronous motion, slip ring 5 removes and can drive displacement sensor 54 and slide fast, displacement sensor 54 detects by oneself and produces by a wide margin and give controller 11 with the signal transmission this moment, controller 11 can start band-type brake servo motor 4 immediately for slider 53 and blind groove 32 block limit the slip of slip ring 5, thereby avoid auto parts to drop to directly produce the damage to ground, the security when improving auto parts maintenance.
When the part maintenance finishes and installs, often need finely tune its position, because inertial effect, hoist engine 22 can make backup pad 6 produce and rock by a wide margin, backup pad 6 can drive first clamp plate 61 extrusion first damping spring 62 when auto parts finely tunes to one side, reduce the effort of rocking that backup pad 6 produced connecting block 7 under the effect of first spring 62, when the effort of rocking is too big, first damping spring 62 is compressed completely, first clamp plate 61 can make second push post 721 drive second movable block 72 synchronous movement this moment, make second movable block 72 extrude second damping spring 64, make second damping spring 64 carry out the shock attenuation to first clamp plate 61, make can assist the shock attenuation through second damping spring 64 when the too big first damping spring 62 of rocking, reduce backup pad 6 and to connecting plate 7's effort, stability when improving the part and lifting by crane.
Because the shape of part is different, so need to adjust the angle of lifting hook 85 at the in-process that lifts by crane the part for lifting hook 85 can adapt to the lifting request of different types auto parts, when not having hung the part on lifting hook 85, make gear 81 and the inner wall laminating of erection column 8 under the effect of second spring 82, but lifting hook 85 free rotation this moment, when lifting hook 85 hangs the part, because the action of gravity, lifting hook 85 can drive gear 81 downwardly extrusion second spring 82, gear 81 can with the draw-in groove 84 block on the erection column 8 inner wall this moment, make gear 81 unable rotation, and then make lifting hook 85 unable rotation, but free rotation when not having hung the part for lifting hook 85, unable rotation when hanging the part, avoid the part to produce the rotation and cause the influence to personnel safety in the maintenance process.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
