The one-time use process of the present invention is described below with reference to the accompanying drawings:
When the height position of the whole vertical fin dock needs to be adjusted, the locking between the vertical fin dock and the movable hanging bracket needs to be temporarily released, and at the moment, only the electric push rod 2 needs to be started to enable the electric push rod 2 to retract downwards, further, the pull rod 3 moves downwards through pulling down the safety rope 6, the thrust spring 4 is gradually compressed, the transmission rod 13 is synchronously driven to move downwards along with the downward movement of the pull rod 3, the first slide block chuck 7 is driven to obliquely move downwards along the first guide rail base 9 along with the movement of the transmission rod 13, meanwhile, the second sliding block chuck 8 is driven to move downwards along the two guide rail bases 10 in an inclined mode, the distance between the clamping surfaces of the first sliding block chuck 7 and the second sliding block chuck 8 is gradually increased till the clamping surfaces of the first sliding block chuck 7 and the second sliding block chuck 8 are separated from the surface of the movable hanging bracket, and then the height position of the whole vertical fin dock can be adjusted.
after the height position of the vertical fin dock is adjusted, the electric push rod 2 is started reversely, the electric push rod 2 extends upwards, the pull rod 3 moves upwards under the action of the spring force of the thrust spring 4, the transmission rod 13 is driven to move upwards synchronously, the first sliding block chuck 7 is driven to move upwards along the first guide rail base 9 in an inclined mode, the second sliding block chuck 8 is driven to move upwards along the second guide rail base 10 in an inclined mode, the distance between the clamping surfaces of the first sliding block chuck 7 and the second sliding block chuck 8 is reduced again at the moment until the clamping surfaces of the first sliding block chuck 7 and the second sliding block chuck 8 abut against the surface of the movable hanging bracket again, and the locking state between the vertical fin dock and the movable hanging bracket is restored.
Once the docking station falls, the rack 1 falls synchronously with the docking station, the electric push rod 2, the safety rope 6, the pull rod 3 and the steel wire rope 11 are driven to move downwards synchronously, but the coiler can rapidly lock the steel wire rope 11 when detecting that the steel wire rope 11 suddenly accelerates to release the rope, the steel wire rope 11 and the pull rod 3 cannot move downwards continuously at the moment, the safety rope 6 can be rapidly snapped with the continuous downward movement of the electric push rod 2, after the safety rope 6 is snapped, the rack 1 is still in a falling trend, the pull rod 3 is in an upward movement trend relative to the rack 1, at the moment, the distance between the clamping surfaces of the first slider chuck 7 and the second slider chuck 8 is further reduced, the friction force between the first slider chuck 7 and the second slider chuck 8 and the mobile hanger is rapidly increased, at the moment, the docking station realizes friction deceleration until the mobile hanger is completely clamped between the first slider chuck 7 and the second slider chuck 8, finally, the purpose of preventing the drop of the vertical fin dock is achieved.
Under extreme condition, if the coiler does not lock wire rope 11 at the very first time, must start by manual mode this moment and prevent weighing down the mechanism, specifically through the free end of pressing down emergency locking handle 20 fast, make emergency locking handle 20's the other end lift up fast with the help of lever principle, and then pull-up pull rod 3 fast to the realization first slider chuck 7 further reduces with the clamping face interval of second slider chuck 8, until removing the gallows and tightly pressing the lock completely and dying between first slider chuck 7 and second slider chuck 8, finally realize preventing the purpose that the vertical fin dock that under the emergency state falls.
The embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications without departing from the scope of the present invention are intended to be included in the scope of the present invention.
