Special lifting appliance for ship gun turret

Abstract

The invention discloses a special lifting appliance for a ship gun turret, which comprises a sling, a transition beam for opening the sling to prevent the turret from being damaged by pulling, and a supporting seat arranged below the turret and used for supporting the turret for lifting, and the slings comprise at least three groups of first slings for uniformly connecting the transition beam with a hoisting device and at least three groups of second slings for uniformly connecting the transition beam with the supporting seat. The second sling further comprises a length adjusting device, and the length of the corresponding second sling can be adjusted through the length adjusting device according to the levelness of the turret, so that the hoisting stability of the turret is effectively guaranteed. The special lifting appliance for the ship gun turret is simple in structure and convenient to install and operate, and the problem that the ship gun turret is difficult to lift is solved with low cost; the levelness of the ship gun during hoisting can be adjusted specifically according to the gravity center of the ship gun, and the hoisting stability is good; and in addition, the lifting device is also suitable for lifting spherical or cylindrical parts and is high in universality.

Description

technical field

[0001] The invention belongs to the technical field of naval gun repair and maintenance, and particularly relates to a special spreader for a naval gun turret. Background technique

[0002] A certain naval gun is a kind of multi-purpose dual-mounted naval gun. As one of the key equipments of my country's active navy, it has completed dozens of maintenance and fault repair projects since the naval gun was listed for more than ten years. Among them, due to the long-term impact of the recoil kinetic energy on the launching system located in the naval gun turret, some wearing parts, stress parts and wear parts are deformed and worn to varying degrees, which all affect the performance of the naval gun. Therefore, for each major overhaul and debugging, the naval gun needs to be split into two parts: the turret and the adapter tube assembly for lifting and transportation, and then returned to the factory for maintenance; but because the turret part of the naval gun ...
