The deviation correcting guide rail 21 is arranged on the operating platform 22 through a guide rail fixing seat 23.
A correction method for a coke dry quenching tank cover comprises the following steps:
1) After the dry quenching furnace red coke is filled, the lifting machine drives the coke tank and the coke tank cover 1 to transversely move to the lifting derrick, and the lifting machine lifts the coke tank cover 1 to start falling;
2) When the lifting beam 11 on the coke tank cover 1 approaches the deviation correcting guide rail 21, the lifter runs at a low speed; the guide carrier roller 12 on the lifting beam 11 moves downwards along the opening of the deviation correcting guide rail 21 to realize forced deviation correction;

The guide rod and the gravity balance beam form a gravity auxiliary balance device, and the dead weight of the gravity balance beam is between 0.5 ton and 2 ton. After the coke tank cover falls down and is subjected to preliminary center alignment adjustment through the forced deviation correcting device, the level of the coke tank cover is adjusted through the gravity balance beam, and the gravity of the gravity balance beam is transmitted to the coke tank cover through the guide rod to carry out gravity auxiliary deviation correction. The gravity balance beam is in sliding connection with the guide rod through the sliding sleeve, and a baffle is arranged at the top of the guide rod to control the travel of the gravity balance beam. The guide rod is connected with the coke tank cover in a hinged mode so as to relieve the stress state of the guide rod and the coke tank cover and avoid frequent damage of the coke tank cover and the guide rod due to impact.
