Abstract

The present invention discloses a novel nuclear power plant steel containment spreader, including a dispenser, a wire rope sling and an angle adapter device. The upper part of the dispenser is provided with a main hanging board in cross structure; the lower part of the dispenser is provided with branch boatswain chair distributors along a circumferential direction; the whole structure is centrally symmetric, and reasonable in bearing; under the hanging article is in a similar weight, the centrally symmetric structure can significantly reduce the weight of the dispenser. The angle adapter device contains an angle adapter and a double level balance beam; the angle adapter adjust the axes of the pin apertures on the directions of 0 DEG, 90 DEG, 180 DEG and 270 DEG on the main hanging board of the dispenser to a same direction in parallel to each other, so that the angle adapter is conveniently connected to the double level balance beam.

Description

technical field [0001] The invention relates to a sling, in particular to a novel nuclear power plant steel containment sling. Background technique [0002] Steel containment is an important structure of AP1000 nuclear power plant, with a diameter of about The total height is about 70m, and the wall thickness is about 45mm. It can be divided into modules such as bottom head 5, cylinder ring sections (2, 3, 4), and top head 1 (such as figure 1 shown), the weight of each steel containment module ranges from 600t to 800t. The steel containment module has the characteristics of large volume, heavy weight and easy deformation. [0003] The steel containment spreader adopts such as figure 2 The hoisting system shown includes distributor 6, wire rope rigging 7 and so on. The wire rope sling 7 is provided with an adjustable pull rod; the other end of the wire rope sling is connected with the lifting lug on the bottom head 5 of the suspended steel containment vessel. [0004] ...
