Embodiment Construction

[0016] Such as figure 1 Shown is a 1000MW reactor coolant pump hook conversion device, the device is a vertical structure, the connecting sleeve 6 penetrates into the hole in the lower part of the conversion seat 1, and is welded with the conversion seat 1 as a whole; the left pin 8 and the right Side pin 17 passes in the double hole of conversion seat 1 top, as figure 2 The shown first boom 2 and the second boom 16 are installed on the left latch 8, as Figure 4 The third boom 14 and the fourth boom 15 shown are installed on the right bolt 17, and the second hex head screw 9 passes through the threaded hole on the lock plate 3 to connect with the left bolt 8 and the right bolt 17 respectively. Fixedly connected, the third hexagonal head screw 11 cooperates with the hexagonal head nut 10 to pass through the threaded hole on the lock plate 3 to connect with the first boom 2, the second boom 16, the third boom 14, and the fourth boom respectively. Arm 15 is fixedly connected...

Abstract

The invention relates to a 1000 MW reactor coolant pump lifting hook conversion device. The device is characterized in that plug pins penetrate into holes in the upper portion of a conversion seat, cargo booms are arranged on the plug pins, hexagonal head screws are matched with stop washers to penetrate through threaded holes in lock plates to be fixed with the plug pins, the hexagonal head screws are matched with hexagonal head nuts to penetrate through the threaded holes in the lock plates to be fixed with the cargo booms, guide sleeves are connected with the cargo booms through the hexagonhead screws and the lock washers, small shafts penetrate into the guide sleeves, and moving rods are arranged in threaded holes of the small shafts. By applying the device, the rapid conversion use of a 1000 MW reactor coolant pump lifting hook can be achieved, the controllability is high, the required manpower is less, the operation is simple, and mounting and dismounting are convenient; and thedevice is convenient to manufacture and is beneficial to saving the cost.

Description

Technical field: [0001] The invention relates to a 1000MW reactor coolant pump hook conversion device. Background technique: [0002] The coolant pump unit for a million-dollar reactor weighs up to 100 tons. It needs to be hoisted and coordinated by a crane from the assembly in the nuclear power plant radioactive machine repair and decontamination workshop to the assembly in the containment. At present, the crane hooks inside the containment of nuclear power plants in China use single-headed hooks due to space considerations, so the lifting tool interfaces of 1000MW reactor coolant pumps are designed according to single-headed hooks; In the decontamination workshop, the crane hooks mostly use double-headed T-hooks. This situation has caused the lifting of the 1000MW reactor coolant pump to be limited by the form of the hook. The operation process of changing the hook of the crane is cumbersome and complicated, and the workload is heavy, which affects the work efficiency. ...
