Embodiment 1

[0030] Embodiment 1 Suspended CV cylinder hoisting rope assembly and disassembly auxiliary device

[0031] combine figure 1 and figure 2 As shown, the CV cylinder hoisting rope assembly and disassembly auxiliary device of this embodiment includes a support platform 1 , a plurality of mounting frames 2 and a plurality of connecting frames 3 using a suspension frame structure. Wherein, the support platform 1 is a ring-shaped platform structure, and its outer diameter is slightly smaller than the inner diameter of the CV cylinder, so that it can be freely hoisted into and out of the cylinder in the vertical direction. A plurality of installation frames 2 are arranged along the circumferential direction of the support platform 1, and the lower end of each installation frame 2 is fixedly connected with the support platform 1 as a connection end, and the upper end is used as a suspension end to extend upwards in the vertical direction. The top of the upper end is provided with a ...

Embodiment 2

[0053] Embodiment 2 Auxiliary device for installation and disassembly of support type CV cylinder hoisting rope

[0054] to combine Figure 10 As shown, the CV cylinder hoisting rope assembly and disassembly auxiliary device of the present invention can also adopt a supporting structure. Compared with the structure of the CV cylinder hoisting rope assembly and disassembly auxiliary device in the first embodiment, the only difference is that the mounting frame 2' in the second embodiment adopts a support frame structure arranged in a horizontal direction. At this time, the support frame as the installation frame 2' adopts a hollow frame structure, one end is connected to the support platform 1, and the other end protrudes in the horizontal direction and is supported and fixed on the inner lug of the CV cylinder. In this way, the crossbeam at the front end of the support frame can be used to build and connect with the lifting lug inside the CV cylinder, and at the same time, th...

Abstract

The invention belongs to the technical field of CV cylinder hoisting and discloses an auxiliary device for assembly and disassembly of a CV cylinder hoisting rope in order to solve the problem that the construction efficiency is low when a rope and lifting lugs are disassembled and assembled in the CV cylinder hoisting process. The auxiliary device comprises a supporting platform, mounting framesand connecting frames. The supporting platform is of a circular-ring-shaped structure, and the outer diameter size of the supporting platform is slightly smaller than the inner diameter size of a to-be-hoisted cylinder; the mounting frames are arranged in the circumferential direction, one ends of the mounting frames serve as connecting ends to be connected with the supporting platform, and the other ends of the mounting frames are detachably connected with the CV cylinder; the lower ends of the connecting frames are connected with the supporting platform, and the lifting lugs are arranged atthe upper ends of the connecting frames; the number of the connecting frames is the same as the number of the lifting lugs inside the to-be-hoisted cylinder, and the positions of the connecting frameson the supporting platform correspond to the positions of the lifting lugs inside the to-be-hoisted cylinder. By adopting the auxiliary device, the efficiency and safe reliability of assembly and disassembly construction of a CV cylinder hoisting rope tool can be improved.

Description

technical field [0001] The invention belongs to the technical field of CV cylinder hoisting, and in particular relates to an auxiliary device for assembling and disassembling a CV cylinder hoisting sling. Background technique [0002] At present, with the continuous development of AP1000 and CAP1400 nuclear power technology, the technology has gradually matured, and nuclear power construction has been carried out on a global scale. Among them, in the construction projects of AP1000 and CAP1400 nuclear power plants, the hoisting operation for the CV cylinder is an extremely important link. [0003] Before the hoisting of the cylinder, it is necessary to carry out the pin connection between the sling and the lifting lug inside the cylinder. Since the lifting lug is located at a high height inside the cylinder, it is usually necessary to set up a temporary working platform in advance near the lifting lug. And under the auxiliary effect of the hoisting equipment to the rigging,...
