The utility model discloses an automatic placing device for workover operation. The automatic placing device comprises a load-bearing bracket and chain driving mechanisms, wherein the chain driving mechanisms are arranged on the left side and the right side at the upper part of the load-bearing bracket; the chain driving mechanisms drive an oil pipe or an oil rod to automatically place on a load-bearing device by moving forwards and backwards themselves; each chain driving mechanism comprises a servomotor, a main chain wheel, a driven chain wheel and chains; the main chain wheel and the driven chain wheel are arranged at the front end and the rear end of the load-bearing device respectively, and are enwound by the closed chains; the servomotor is connected with the main chain wheel, and drives the main chain wheel to rotate; a hydraulic lifting mechanism is arranged at the bottoms of the chain driving mechanisms; locking devices are arranged on the chains; a vertical baffle is arranged at the end part of the load-bearing bracket. The automatic placing device is matched with an on-site automatic operation system, and can integrally improve the automatic level of the whole operation system, greatly reduce the labor intensity of workers, improve the production operational efficiency, and greatly reduce the probability of safety accidents simultaneously.
